The coating device 3 also has an inclined coating outlet 31 at one end, with the feed inlet 30 communicating with the coating outlet 31. The peristaltic pump 16 is used to transfer the hydrogel from the hydrogel mixer 15 to the coating device 3. Specifically, one end of the peristaltic pump 16 is connected to the feed valve of the hydrogel mixer 15 via a pipeline, and the other end is connected to the feed inlet 30 of the coating device 3. The bottom of the coating outlet 31 of the coating device 3 is positioned close to the top surface of the pearlescent film on the coating conveyor belt 21, allowing the hydrogel to flow out evenly and be coated onto the pearlescent film. A hydrogel fine-tuning component 32 is provided on the top of the coating device 3. The hydrogel fine-tuning component 32 can adjust the flow of hydrogel between the feed port 30 and the coating outlet 31, thereby adjusting the coating thickness of the hydrogel coated on the pearlescent film.

[0040] The cooling device 4 comprises a cooling conveyor belt 22 mounted at one end of the coating conveyor belt 21 and several fan modules 40 mounted above the cooling conveyor belt 22. The coating conveyor belt 21, cooling conveyor belt 22, and pearlescent film conveyor belt 23 are integrally formed. When the hydrogel is applied to the pearlescent film surface by the coating device 3, the hydrogel is still in a hot melt state. The cooling device 4's several fan modules 40 rapidly cool the hydrogel to cool down and stabilize its cohesion.

[0041] The cutting and forming device 5 includes a pearl film conveyor belt 23 installed at one end of the cooling device 4, a rolling cutter mechanism 50 is installed at one end of the pearl film conveyor belt 23, and a facial mask conveyor belt 24 is installed at one end of the rolling cutter mechanism 50. Among them, the front end of the rolling cutter mechanism 50 is the pearlescent film conveyor belt 23, and the rear end thereof is the facial mask conveyor belt 24. The cutting and forming device 5 also includes a transition support plate 51 installed between the pearlescent film conveyor belt 23 and the rolling cutter mechanism 50.

[0042] The cutting and forming device 5 cuts the pearlescent film into facial masks according to the following working principle: the cooling device 4 conveys the pearlescent film to the pearlescent film conveyor belt 23, which conveys the pearlescent film to the blade roller 52 of the rolling cutter mechanism 50. The rotation of the blade roller 52 drives the rolling cutter roller 53 to rotate. As the rolling cutter roller 53 rotates, the blade 530 on its outer cylindrical surface rolls the pearlescent film, thereby rolling the pearlescent film into facial masks and facial mask waste. Then, the blade roller 52 continues to rotate, and one end of the facial mask is scraped by the scraper 54, separating the facial mask from the blade roller 52. The facial mask then enters the facial mask conveyor belt 24, and the facial mask waste is pulled up and conveyed to the facial mask waste collection device 6.

The limiting component 73 includes a first limiting steel wire 731 and a second limiting steel wire 732. One end of the first limiting steel wire 731 is installed at one end of the second mounting frame 12, and one end of the second limiting steel wire 732 is installed at the other end of the second mounting frame 12. The first clamping component 741 includes a first clamping steel wire 741 and a second clamping steel wire 742.

The press forming belt 750 is installed at one end between the first pressing steel wire 741 and the second pressing steel wire 742. The press forming belt 750 is installed above the folding conveyor belt 25.

[0045] The working principle of the above-mentioned mask folding device 7 for folding the mask is as follows: first, the mask conveyor belt 24 conveys the mask to the folding conveyor belt 25; then, when the mask enters the folding conveyor belt 25, the two downward pressing rollers 700 of the downward pressing roller assembly 70 respectively press down and pre-tighten the top surface of the mask, so that the friction between the mask and the folding conveyor belt 25 increases, and the mask effectively contacts the folding conveyor belt 25, so that the folding conveyor belt 25 can drive the mask to move forward; then, the width positioning assembly 72 contacts the top surface of the mask, and the folding assembly 71 contacts the bottom surface of the mask; then, the first folding steel wire 711 folds one end of the mask. When folding, the first width positioning steel wire 721 limits the folding width of one end of the mask, playing a role of width positioning. After the first folding steel wire 711 folds one end of the mask, the second folding steel wire 712 folds the other end of the mask. Similarly, when folding, the first folding steel wire 711 The second width positioning steel wire 722 limits the folding width of the other end of the mask, playing a role in width positioning; after the folding is completed, the first limiting steel wire 731 limits one end of the mask to prevent the folding size part of one end of the mask from recovering and deforming, and the second limiting steel wire 732 limits the other end of the mask to prevent the folding size part of the other end of the mask from recovering and deforming; then, the first pressing steel wire 741 pre-presses one end of the mask, and the second pressing steel wire 742 pre-presses the other end of the mask. The first pressing steel wire 741 and the second pressing steel wire 742 prevent the folded mask from recovering and expanding, thereby preventing the folded mask from being unable to enter the pressing and molding belt 750; then, the folded mask is pressed and molded by the pressing and molding belt 750, and the pressing and molding belt 750 and the folding conveyor belt 25 move forward synchronously to jointly transport the folded mask to the bagging conveyor belt 26. The downward pressing roller assembly 70, folding assembly 71, width positioning assembly 72, limiting assembly 73, first pressing assembly 74 and second pressing assembly 75 of the mask folding device 7 jointly complete the folding action of the mask, which can prevent errors in manual folding and contamination of the mask caused by its operation, and ensure that the mask folding is consistent and beautiful.

[0046] Among them, in this embodiment, two bagging devices 8 are provided, and the two bagging devices 8 alternately put the folded facial masks into bags so that the two are formed into finished facial masks.

[0047] A bagging conveyor belt 26 is installed at one end of the facial mask folding device 7, and the bagging device 8 includes at least one bag feeding mechanism 80 installed on one side of the bagging conveyor belt 26 and used to transport the bag to the bottom of the bagging conveyor belt 26, a folding and inserting bag mechanism 81 installed above the bagging conveyor belt 26 and used to fold the facial mask in half and insert it into the bag below the bagging conveyor belt 26, and a chute guide mechanism 82 installed below the folding and inserting bag mechanism 81 and used to transport the finished facial mask to the finished facial mask conveyor belt 27 after the facial mask is inserted into the bag to form a finished facial mask. The top of the chute guide mechanism 82 is equipped with a bag clamping cylinder assembly 820 for clamping the facial mask and the middle part of the bag when the folding and inserting bag mechanism 81 folds the facial mask in half and inserts it into the bag to prevent the facial mask from being pulled out when the folding and inserting bag mechanism 81 is reset. There are two bag feeding mechanisms 80, each mounted on either side of the bag loading conveyor belt 26. The two bag feeding mechanisms 80 alternately feed bags to the bottom of the bag loading conveyor belt 26. The bag feeding mechanisms 80 include a bag storage assembly 800, a bag taking assembly 801 mounted at one end of the bag storage assembly 800, a bag feeding and opening assembly 802 mounted at one end of the bag taking assembly 801, and a linear drive module 803 mounted at one end of the bag feeding and opening assembly 802 for driving the bag feeding and opening assembly 802 to reciprocate.

A push plate 8003 is mounted at the rear end of the bag storage box 8000 to push the bag out of the box. Stoppers 8004 are mounted on both sides of the front end of the bag storage box 8000 to hold the two ends of the bag. The push plate 8003 uses its own weight to push the bag toward the stops 8004 on both sides of the bag storage box 8000. The bag removal assembly 801 includes several retractable pneumatic suction cups 8010, which extend toward the front end of the bag storage assembly 800 to suck a bag out of the bag storage box 8000. The ends of the bag deform and can then be released from the two stops 8004. After the bag is released from the stops 8004, the ends of the bag return to their original shape. The bag delivery and opening assembly 802 includes a pneumatic suction cup clamp 8020. A linear drive module 803 reciprocates the pneumatic suction cup clamp 8020 of the bag delivery and opening assembly 802 from above the pneumatic suction cup 8010 of the bag retrieval assembly 801 to below the bag loading conveyor 26. The bag folding and inserting mechanism 81 includes a folding and inserting piece 810 and a lift drive motor mounted at one end of the folding and inserting piece 810 to control the raising and lowering of the folding and inserting piece 810.

The finished facial mask conveyor 27 is located at the bottom of the chute of the chute guide mechanism 82.

[0048] The working principle of the above-mentioned bagging device 8 for packing the facial mask into the bag so that the two are formed into the finished facial mask is as follows: first, the folding conveyor belt 25 transports the folded facial mask to the bagging conveyor belt 26, and the bagging conveyor belt 26 transports the facial mask to the bottom of the folding and inserting bag piece 810 of the folding and inserting bag mechanism 81; then, the pneumatic suction cup 8010 of the bag taking component 801 absorbs a bag from the bag storage box 8000 of the bag storage component 800 of the bag feeding mechanism 80, and the bag is taken out from the storage box 8000. The bag box 8000 is disengaged from the stopper 8004; then, the linear drive module 803 moves the bag feeding and bag opening component 802 to the bottom of the bag taking component 801, and the pneumatic suction cup clamps 8020 of the bag feeding and bag opening component 802 respectively adsorb the top two ends of the bag, and the pneumatic suction cup clamps 8020 open the bag; then, the linear drive module 803 moves the bag feeding and bag opening component 802 to the bottom of the folding and inserting bag piece 810; then, the folding and inserting bag machine The lifting drive motor of the mechanism 81 controls the folding and inserting bag piece 810 to move downward, and the folding and inserting bag piece 810 folds the folded mask in half and inserts it into the bag; then, the bag clamping cylinder assembly 820 of the chute guide mechanism 82 clamps the middle of the bag, and at this time, the clamping cylinder in the bag clamping cylinder assembly 820 is located in the inverted U-shaped opening groove 8100 of the folding and inserting bag piece 810 and clamps the bag and the folded mask together, so at this time, the clamping cylinder and the chute guide mechanism 82 The folding and inserting bag pieces 810 do not interfere with each other, and the clamping cylinder will not affect the resetting movement of the folding and inserting bag pieces 810; then, the lifting drive motor of the folding and inserting bag mechanism 81 controls the folding and inserting bag piece 810 to reset upward; then, the pneumatic suction cup clamp 8020 of the bag feeding and opening assembly 802 releases the bag, and the bag clamping cylinder assembly 820 of the chute guide mechanism 82 resets, causing the bag to fall into the chute in the chute guide mechanism 82 and slide onto the finished facial mask conveyor belt 27. There are two bagging devices 8, of which the bag feeding mechanisms 80 in the bagging device 8 are two, which greatly improves the efficiency of facial mask bagging and realizes fully automatic and continuous bagging. The bagging device 8 ensures that after the facial mask is folded in half and placed in the bag, part of the facial mask will not be extracted. At the same time, the bagging device 8 also has the advantages of ensuring the consistency of facial mask bagging quality, avoiding placement errors during manual bagging, and being suitable for different bag sizes.

[0049] The bagging device 8 also includes a bag-blocking mechanism 83 mounted at the bottom of the chute guide mechanism 82 to support the bottom of the finished facial mask; an exhaust mechanism 84 mounted to one side of the bag-blocking mechanism 83 to compress and exhaust the finished facial mask; and a sealing and welding mechanism 85 mounted to one side of the exhaust mechanism 84 to seal the finished facial mask. Together, the bag-blocking mechanism 83, exhaust mechanism 84, and sealing and welding mechanism 85 seal the finished facial mask. Therefore, the bagging device 8 can meet the needs of some customers for sealing finished facial masks.
