Following the above artical How N95 automatic mask machine work-1? We continue to talk about the N95 mask machine working .
Moving on to the other mechanisms for N95 automatic mask machine , the function of the guide mechanism is to prevent the nasal bridge line from running off, as can be seen from the picture,
the two left-most and right-most rollers are V-shaped, which restricts the nasal bridge line from running off to the sides.
The nose line exits the guiding mechanism, passes through the sensor mounting block, then through the middle of the counter roller roller and into the back feed
channel. It is the drive cam on top that drives the rollers, and every time the cam rotates, it touches the rollers once, and when it does, it drives the rollers to rotate.
Note: Some people may ask: why use two cams, one will not achieve the purpose (in fact, I thought so at first, hahaha), in fact, the purpose is to use two cams, you
can adjust the angle of contact roller at will, so that you can adjust the length of the nose line each feed.
3.Nose line loading mechanismFirst of all, the pushrod has fisheye joints on both ends, it's just that the model opens up with missing parts, so it doesn't show up, and
everyone will be fine knowing that.
The mechanism moves in the following sequence N95 automatic mask machine : the eccentric wheel rotates to drive the pushrod and plate forward, sending the nose line into the middle of the fabric.
As you can see, the power of the embossing mechanism also comes from the power shaft, and this power shaft is the same as the power shaft of the previous nose line
feeding & loading mechanism; and as for how the power is transferred between the gears, you can download the 3D model to see in detail. Moving on to the details of this
institution.
Let's look at it one by one for N95 automatic mask machine .
Embossing position: It is a roller with a lot of grain (not expressed on the model) that is used to press out the grain on the outside of the N95 mouthpiece. The reason for this
is the following ultrasonic welding head and vibrator, which has already been mentioned in the analysis of the disposable mask machine, so let's leave it at that.
The adjustment mechanism of this station for N95 automatic mask machine is clear: the top and bottom top screws hold the slider in place, and the middle spring is designed to automatically lift the embossed roller up when the top screw is loosened, without the need to screw the bottom top screw.
Cut out the breathing valve hole station: The drum has a protruding circle which is used to cut out the hole where the breathing valve is installed, and the cut out waste is discharged
through the hopper. However, this mask machine does not have a station with a breathing valve on the back, so this station is not used (in the video above, this station is not used).
Roller to roller mechanism: to provide driving force for the fabric forward; about the role and principle of the upper roller adjustment mechanism, it has been said before, there are
students who do not yet understand can turn forward.
Printing process & fusion welding process
These two processes are mentioned together because they are related to each other in the actual production process.
As can be seen, the left and right earbands are connected by screw between the welding mechanism and the pad printing mechanism, and at the same time they can move together
along the rails of the frame, the drive source is the servo motor + screw mechanism under the frame.
And as for why the above institutions are campaigning for N95 automatic mask machine ?
The reason is: the fabric is always in forward motion, while the pad printing mechanism and the welding earbands need to be in contact with the fabric when working, so it is necessary
to ensure that the fabric and the above two mechanisms when in contact, there is no relative motion. Therefore, the transfer mechanism and the fused earband mechanism need to
advance with the fabric when in contact with the fabric and return when separated from the fabric.
After explaining the connection between institutions, and the reasons why institutions want to move, the next step is to continue the analysis of institutions one by one.
I. Transfer printing process
We often see the N95 masks with this writing on both sides, made using this process.
Let's take a look at the structure of the pad printing process for N95 automatic mask machine
First of all, the principle of the left and right pad printing mechanism is the same; this printing process uses the pad printing process, and later on in the process of the pad printing can be said in passing.
1.the end of the seal and the movement of the oil printing box is through the synchronous belt + rail mechanism: motor drive synchronous belt wheel movement, and then the sliding mechanism and the synchronous belt fixed, you can do linear motion; this mechanism is relatively simple, but it is very common, so you can remember, used for later design other equipment.
2 the order of action (in fact, it is the process of transfer printing): 1) the oil printing box first on the transfer printing base plate coated with pigment.
2) The seal moves to the top of the pad-printing base plate, then the double-axis cylinder presses down, the seal is stained with pigment; 3) Finally the seal moves to the top of the position where the fabric passes, the double-axis cylinder presses down, you can print the pigment on the fabric.
II. Welding of earbands of N95 automatic mask machine
The left and right earbands have the same fusion mechanism and principle, but in different positions, so we can analyze one of them.
In order to give a more detailed account of the whole process, let's start with the approximate steps of the whole process.
→ The earbands come out of the feed mechanism and onto the earbands pull fusion mechanism; → then the earbands pull fusion mechanism, pull the earbands, and the earbands are cut off by the earbands cutter mechanism; → finally the earbands pull fusion mechanism, and the earbands are fused to the mouthpiece.
Well, that's roughly the order of work, and then we begin to analyze the institutions in order.
1.Ear band feeding mechanism of N95 automatic mask machine
This is the same mechanism that was originally used on the disposable mask machine, but I forgot to analyze it at the time, so I took it with me this time.
Path of the earbuds.
Earbud rolls - Drive wheels & compression wheels - Adjustment wire wheels - Overwire wheels - Overwire holes for N95 automatic mask machine
It can be seen that the compression wheel presses the earbands against the drive wheel, which continues downward as the drive wheel rotates; at the other end, the earbands are connected to the pull-out mechanism after passing through the overwire hole. But obviously, the discharge and pulling speed of the earbands won't match, so the adjusting wire wheels are there to adjust the tightness of the earbands.
When the drive wheel drives the earbands out, the earbands will be loosened, then the adjusting wire wheel due to gravity drop, until detected by the sensor, the drive motor stops working; at this time, the pulling mechanism will continue to pull the earbands, the adjusting wire wheel upwards, when the sensor cannot detect the adjusting wire wheel, the drive motor starts working again immediately, so that the earbands start to discharge. Just keep cycling this discharge.
1.Earthband pulling and welding mechanism of N95 automatic mask machine
The ultrasonic vibrator and weld head on the left, already explained, so no more nonsense.
Focusing on the right side, since the picture may not be very clear, so let's start with the connection relationship between the parts.
The down-pressure cylinder drives the retaining plate; the upper part of the fused tie rod is threaded and locked to the retaining plate by a locking nut.
The fused tie rod and the ear strap pull and handling mechanism are relatively sliding (see details on the end of the fused tie rod), but when the fused tie rod rises to the end to contact the ear strap pull mechanism, it holds the entire ear strap pull mechanism up.
The above is the special explanatory note to be made. Let's go back to the principle of vertical motion for N95 automatic mask machine .
→ The downward pressure cylinder drives the fixed plate downward; → The fixed plate drives the fused tie rod downward; → At this time, the earbud pulling mechanism, which was originally held up by the fused tie rod, starts to go downward because of gravity; → When the earbud pulling mechanism is finished, the downward pressure cylinder drives the fused tie rod further downward until the end is finished.
→ The lower pressure cylinder drives the fixing plate upwards; → The fixing plate drives the fused tie rod upwards until the end contacts the ear strap pulling mechanism and the two begin to move upwards together; → Until it rises to the cylinder limit.
1) Next, let's analyze the earband pulling and processing mechanism.
Above are two different angles of the ear strap pull & handle mechanism, and a detailed picture of the end claws.
Let's start by explaining the role of some parts.
(1) The sensor detects the motor's rotation induction block and controls the angle of rotation (180° per rotation); (2) The shrapnel in the end claw can be passed through the steel ball to keep the claw in place (it will not spring up after being pushed down by the block).
③ The paws become this way when they are pressed down by the paw block (the earbands can be tightened to prevent them from falling off).
Then the order of work of this body (the most important) for N95 automatic mask machine .
→ In the initial state, one end of the earbands passes through the wire wheel and is pressed under the claw-1.
→ At this point, the rotating motor rotates the end paw to the right by 180°, and the paw-1 presses the end of the earbands will automatically pull the earbands to the following state.
→ The paw cylinder drives the paw block down, pressing the paw down, pressing the earbands, and the earbelt clipping mechanism cuts the earbands and returns them with the paw block; (the principle of clipping will be described later)
→ Next, the entire mechanism begins to press down until the two wire blocks are pressed against the ends of the earbands.
→ After the earbands are fused to the mouthpiece by the line block, the line cylinder drives the line down, and while the line is pushing the earbands off the winding block, the line mounting plate will press down the paws-2 & paws-3 & paws-4 at the raised end, thus restoring the paws at these three places to their original state, while the paws can put down the cut earbands (note: the paws at paws-1 are not pressed, so they will not come loose).
Note: If you press the line to mount the plate, you will only press the paws at Paw-2 & Paw-3 in the subsequent movements, because the paws at Paw-4 will be followed by the restored paws (a bit of an argument, you'll understand after thinking about it).
→ The entire mechanism rises and the earbands are successfully fused to the mouthpiece. By repeating the above process, the earbands can be quickly pulled and fused.
1.Ear band cutting mechanism of N95 automatic mask machine
The purple part is used to adjust the angle and position of the ear strap cutter mechanism, I've already marked it, so I won't go into detail.
Just a special note: the pusher pin holes and the scissors rotation axis are manufactured with pins; the spring holes (one on each side) should also have springs, either because the original author didn't add them or because the model opened with an error and didn't show them.
Then there's the matter of knowing that there's no connection between the push block and the green part and the scissor limit block in the diagram, which can be slid, which may not be clearly expressed in the diagram, so I'll remind everyone.
The order of work of this body.
→ The cylinder pushes the front end of the mechanism to the earbands; → When the scissors limit block hits the above-mentioned jaw block (see the picture below), the cylinder continues to push, at which point the block pushes the scissors to form a closure, thus clipping the earbands.
→ When returning, the spring on the push block separates the push block from the scissors limit block and the scissors return to the open state again.
The above is how the earbud cutting mechanism works, well, finally analyzed a big part of the whole device ,Continued below.
Labeling process of N95 automatic mask machine
This labeling mechanism is the label on the inside of the mask, but my impression is that there is no label on the inside of the N95 mask, maybe I haven't seen it yet, but since this mechanism is here, let's analyze it together.
In fact, this is a standard labeling agency, friends who have done labeling machine should be very familiar with, specific to see the picture
When the fabric passes through from above, the labeling mechanism will stick the label on the fabric, then look at the specific details of the labeling mechanism (Note: the adjustment mechanism is the use of a screw, specific details, you can see the 3D model).
First, take a look at the working order of the label paper for N95 automatic mask machine
Label tray - passes underneath the three rollers - passes between the stripper and platen while the label on the backing paper is attached to the mask - the backing paper passes through the traction mechanism and ends up on the backing paper roller
The power to move the label forward depends on the pull of the traction mechanism, while the power to move the traction mechanism and the liner roller comes from the motor on the active wheel.
Let's look at the role of some of these institutions.
Tensioning roller: keeps the label paper taut, it works as follows.
The tensioning roller has a shrinking coiling spring at the rotation of the tensioning roller, and when the label paper is loose, the tensioning roller is supported by the stress of the coiling spring to keep the label paper taut.
Push the cylinder: To label, push the cylinder to push the stripper and pressure plate on the mask to label; after labeling, return.
Mask Cutting & Waste Disposal for N95 automatic mask machine
In this process, the overfeed mechanism, the role of the roll mechanism 1-4 are all to pull the mask forward, their driving force is from the power shaft (the power shaft and the front is the same), and the specific power transfer mode, you can download the three-dimensional model to study in detail; about these mechanisms of the regulating mechanism principle and role in the previous have said.
First, then the mask folding mechanism.
We all know that the N95 mask is folded up, and the mask in the front process is always spread, so the function of this process is to fold the original spread mask, and then into the roller roller-1.
II. Non-powered roller stations for N95 automatic mask machine
This station is relatively simple, but the way it is adjusted can be said.
By turning the corrugated handle, the drive shaft is rotated, and then the bevel tooth drive mechanism is used to drive the screw to adjust the position of the movable roller.
III. Mask-cutting stations
(a) The screw drive module drives the entire mechanism in a reciprocating motion, the purpose of which, as before, is to ensure that there is no relative displacement from the mask.
Folded masks are cut by cutting embossed molds and heated by ultrasound.
IV. Earbud stations for N95 automatic mask machine
The earbands are all facing down until they pass through the earbud position, and as we can see by watching the video above, the earbands are all facing up when the mouthpiece finally comes out, so what this position does is flip the mouthpiece earbands that pass through the middle to the top.
V. Mask output stations for N95 automatic mask machine
The discharge belt takes the mask out and the waste material that is cut off at the same time is discharged from the following path: Roller-1→Roller-2→Roller-3→Roller-4→Drive roller & press roller.
And the power of the scrap collection mechanism, the same power shaft, is transmitted through the bevel gear mechanism. Let's take a look at the power shaft with the most appearances and where it gets its power from.
As can be seen, the power source is two servo motors + reducers, whose power is then passed through a power shaft to the various processes.
The whole equipment is divided into several racks, so in order to separate the racks without removing the whole power shaft, the cross universal retractable coupling (standard part) is used where the rack is docked in the picture.
The above is the operation and mechanism analysis of the N95 automatic mask machine
Following the above artical How N95 automatic mask machine work-1? We continue to talk about the N95 mask machine working .
