Description

Technical Field

[0001] This invention relates to the technical field of facial mask production, specifically to a facial mask cutting device and its cutting method. Background Technology

[0002] As is well known, a mask cutting device is an auxiliary device used in mask production to cut and shape the raw materials for masks, and it is widely used in the field of mask production.

[0003] A search of Chinese Patent Publication No. CN208930446U reveals a mask cutting device and production line, which is roughly described as follows: it includes a cutting support, a first pair of pressure rollers, and a cutting drive mechanism; the first pair of pressure rollers includes a blade roller and a bottom roller arranged parallel to each other on the cutting support, and the blade roller is provided with a cutting blade, which includes a substrate for winding around the periphery of the blade roller and a cutting edge protruding from the surface of the substrate. The cutting edge and the bottom roller contact each other when rotating to cut out the mask substrate, which can solve the problem in the prior art that the cutting edge on the surface of the blade roller is integrated with the blade roller, which has a high processing cost and is not universal.

[0004] When using existing mask cutting equipment and production lines, it has been found that cutting the mask using a blade roller can result in the openings on the mask not being completely cut off, which affects the production and processing of the mask. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a mask cutting device and method that can improve the success rate of mask cutting, reduce post-cut adhesion, and ensure the production and processing of masks.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a mask cutting device, comprising a cutting roller, multiple cutting plates, two conveyor belts, and a cutting mold. The cutting roller is provided with multiple cutting grooves, each groove having a fixing plate installed inside it. Two rows of cutting springs are fixed to each fixing plate. The multiple cutting plates are located inside the multiple cutting grooves and are connected to the outer sides of the multiple cutting springs. Each cutting plate is provided with a cutting blade. Multiple connecting rods are rotatably connected to the front and rear roller shafts of the cutting roller, with each connecting rod corresponding to the previous one. Each of the multiple limiting plates is fixed in place, with the inner side of each limiting plate contacting the outer side of the cutting roller. Each of the multiple limiting plates has a guide plate on one side, and the outer sides of the multiple guide plates are inclined towards the outer side of the cutting roller. A limiting ring is fitted in the middle of the cutting roller, and a limiting notch is provided at the lower part of the limiting ring. The limiting ring passes through the middle of the inner side of the multiple limiting plates. The cutting mold is located below the cutting roller, and support legs are installed at the four corners of the bottom of the cutting mold. The cutting roller is mounted above the cutting mold via a frame. Two conveyor belts are installed on the front and rear sides of the top of the cutting mold. The cutting mold has cutting through holes, and the shape and arrangement of the cutting blades match the cutting through holes.

[0009] A first magnetic block is embedded in the side of the guide plate facing the cutting groove. The cutting blades of the cutting plate are all closed or partially closed. A second magnetic block is attached and fixed in the closed or semi-closed area formed by the cutting blades. The thickness of the second magnetic block is slightly less than the height of the cutting blade body. The sides of the first magnetic block and the second magnetic block that are close to each other have the same magnetic poles.

[0010] Preferably, pressure rollers are fitted at both ends of the cutting roller shaft, and the bottom of the pressure rollers contacts the top of the cutting mold.

[0011] Preferably, multiple pressure roller protrusions are evenly arranged around the outer perimeter of the pressure roller.

[0012] Preferably, the cutting mold is provided with multiple buffer pads, all of which are located on the outside of the cutting through hole.

[0013] Preferably, a discharge pipe is provided below the cutting mold, a discharge hopper is provided at the bottom end of the discharge pipe, a discharge fan is installed at the bottom end of the discharge hopper, a discharge pipe is installed at the bottom of the discharge fan, and a waste bin is installed on the bottom plate of the discharge pipe.

[0014] The cutting method of the above-mentioned mask cutting device includes the following steps:

[0015] Step 1: Use a conveyor belt to transfer the mask to be cut onto the cutting mold;

[0016] Step 2: Drive the cutting roller to rotate, drive multiple connecting rods to rotate synchronously, and make the connecting rods rotate faster than the cutting roller;

[0017] Step 3: When one of the multiple cutting plates rotates to the bottom, the limiting plate separates from the cutting groove, causing the cutting spring to quickly eject the cutting plate, so that the cutting blade presses against the cutting mold to complete the cutting of the face mask. During the contact between the cutting blade and the face mask material, the mutual attraction between the first and third magnetic blocks compacts the central enclosed area of ​​the face mask material, and the elasticity of the cutting blade quickly cuts into place, so that the face mask is quickly cut and separated.

[0018] Step 4: After cutting is completed, the cutting plate and cutting spring retract, and the cutting plate is pushed back into the cutting groove by the rotation of the rear limiting plate. The limiting ring is used to restrict the cutting plate in the cutting groove. During this process, the mutual repulsion between the guide plate 10 on the limiting plate 9 and the first magnetic block allows the cutting blade 7 to be guided smoothly back into the cutting groove.

[0019] Step 5: The conveyor belt continues to transport the face mask and repeats steps 3 and 4 to achieve cyclic cutting and processing of the face mask.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the present invention provides a mask cutting device and a cutting method thereof, which have the following beneficial effects:

[0022] This mask cutting device uses a limiting ring and a limiting plate to confine the cutting plate within the cutting groove. When the cutting plate rotates, the limiting plate rotates slightly faster than the cutting roller. When the cutting plate reaches the bottom of the cutting roller, the limiting plate separates from the cutting groove. Simultaneously, the notch in the cutting groove aligns with the notch in the limiting ring, causing the cutting spring to quickly eject the cutting plate, causing it to collide with the cutting mold and allowing the cutting blade to complete the cutting of the mask. After cutting, the rear limiting plate pushes the cutting plate into the cutting groove via a guide plate and continues to rotate, using the limiting ring to further confine the cutting plate. Meanwhile, the rear cutting plate continues to eject, continuously repeating the cutting process to improve the success rate of mask cutting, reduce post-cut adhesion, and ensure the smooth production and processing of the mask.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-4The present invention discloses a mask cutting device, comprising a cutting roller 1, multiple cutting plates 2, two conveyor belts 3, and a cutting mold 4. The cutting roller 1 has multiple cutting grooves, each containing a fixing plate 5. Two rows of cutting springs 6 are fixed to each fixing plate 5. The multiple cutting plates 2 are located inside the multiple cutting grooves and are connected to the outer sides of the multiple cutting springs 6. Each cutting plate 2 is equipped with a cutting blade 7. Multiple connecting rods 8 are rotatably connected to the front and rear roller shafts of the cutting roller 1. Each connecting rod 8 corresponds one-to-one with the multiple connecting rods 8 on the rear side. Limiting plates 9 are fixed between the multiple connecting rods 8 on the front side and the multiple connecting rods 8 on the rear side. The inner sides of the multiple limiting plates 9 are in contact with the outer sides of the cutting roller 1. A guide plate 10 is provided on one side of each of the multiple limiting plates 9. The outer sides of the multiple guide plates 10 are inclined towards the outer side of the cutting roller 1. A limiting ring 11 is fitted into the middle of the cutting roller 1. A limiting notch is provided at the lower part of the limiting ring 11. The limiting ring 11 passes through the inner center of the multiple limiting plates 9. The cutting mold 4 is located below the cutting roller 1. Support legs 12 are installed at the four corners of the bottom of the die 4. The cutting roller 1 is mounted above the cutting die 4 via a frame. Two conveyor belts 3 are installed on the front and rear sides of the top of the cutting die 4. The cutting die 4 is provided with cutting through holes 13. The shape and arrangement of the cutting blades 7 match the cutting through holes 13. The cutting plate 2 can be restricted within the cutting groove by the limiting ring 11 and the limiting plate 9. When the cutting plate 2 rotates, the limiting plate 9 rotates slightly faster than the cutting roller 1. When the cutting plate 2 rotates to the bottom of the cutting roller 1, the limiting plate 9 separates from the cutting groove. At the same time, the cutting... The notch of the groove aligns with the notch of the limiting ring 11, causing the cutting spring 6 to quickly eject the cutting plate 2, which then collides with the cutting mold 4, allowing the cutting blade 7 to complete the cutting of the face mask. After cutting, the limiting plate 9 on the rear side pushes the cutting plate 2 into the cutting groove through the guide plate 10, and continues to rotate while the limiting ring 11 restricts the cutting plate 2. At the same time, the cutting plate 2 on the rear side continues to eject, and by continuously repeating the cutting of the face mask, the success rate of face mask cutting is improved, the occurrence of adhesion after cutting is reduced, and the production and processing of face masks is guaranteed.

[0030] A first magnetic block is embedded in the side of the guide plate 10 facing the cutting groove. The cutting blades 7 of the cutting plate 2 are all closed or partially closed. A second magnetic block is attached and fixed in the closed or semi-closed area formed by the cutting blades of the cutting plate 2. The thickness of the second magnetic block is slightly less than the height of the cutting blade 7 body. The sides of the first magnetic block and the second magnetic block that are close to each other have the same magnetic poles.

[0031] It should also be noted that both ends of the cutting roller 1 are fitted with pressure rollers 14. The bottom of the pressure rollers 14 contacts the top of the cutting mold 4. By rotating with the mask and the conveyor belt 3, the pressure rollers 14 can prevent the mask from bulging during cutting, thus improving the accuracy of mask cutting. Multiple pressure roller protrusions 15 are evenly arranged around the outer perimeter of the pressure rollers 14, which can improve the contact between the pressure rollers 14 and the mask. Multiple buffer pads 16 are provided on the cutting mold 4, and the multiple buffer pads 16 are all located outside the cutting through holes 13. On the side, the impact force when the cutting plate 2 collides with the cutting mold 4 can be reduced by the buffer pad 16; a discharge pipe 17 is provided below the cutting mold 4, a discharge hopper 18 is provided at the bottom of the discharge pipe 17, a discharge fan 19 is installed at the bottom of the discharge hopper 18, a discharge pipe 20 is installed at the bottom of the discharge fan 19, and a trash can 21 is installed on the bottom plate of the discharge pipe 20. The discharge fan 19 can suck the cut mask into the trash can 21 during mask cutting, which facilitates the centralized processing of scraps and further prevents sticking after cutting.

[0032] The cutting method of the above-mentioned mask cutting device includes the following steps:

[0033] Step 1: Use conveyor belt 3 to transfer the mask to be cut onto the cutting mold 4;

[0034] Step 2: Drive the cutting roller 1 to rotate, drive multiple connecting rods 8 to rotate synchronously, and make the speed of the limiting plate 9 faster than that of the cutting roller 1;

[0035] Step 3: When one of the multiple cutting plates 2 rotates to the bottom, the limiting plate 9 separates from the cutting groove, causing the cutting spring 6 to quickly eject the cutting plate 2, so that the cutting blade 7 presses against the cutting mold 4 to complete the cutting of the face mask. During the contact between the cutting blade 7 and the face mask material, the mutual attraction between the first and third magnetic blocks compacts the middle enclosed area of ​​the face mask material. Combined with the elasticity of the cutting blade 7, the cutting is quickly completed, so that the face mask is quickly cut and separated.

[0036] Step 4: After cutting is completed, the cutting plate 2 and the cutting spring 6 retract, and the cutting plate 2 is pushed back into the cutting groove by the rotation of the rear limiting plate 9. The limiting ring 11 is used to restrict the cutting plate 2 in the cutting groove. During this process, the mutual repulsion between the guide plate 10 on the limiting plate 9 and the first magnetic block allows the cutting blade 7 to be guided smoothly back into the cutting groove.

[0037] Step 5: Conveyor belt 3 continues to transport the face mask and repeats steps 3 and 4 to achieve cyclic cutting and processing of the face mask.

[0038] In summary, the working principle and process of this mask cutting device are as follows: During use, the conveyor belt 3 transports the mask to be cut to the cutting mold 4. Then, the cutting roller 1 is driven to rotate, and multiple connecting rods 8 are driven to rotate synchronously, with the connecting rods 8 rotating faster than the cutting roller 1. When one of the multiple cutting plates 2 rotates to the bottom, the limiting plate 9 separates from the cutting groove, causing the cutting spring 6 to quickly eject the cutting plate 2, so that the cutting blade 7 presses against the cutting mold 4, completing the cutting of the mask. After cutting, the cutting plate 2 and the cutting spring 6 retract, and the cutting plate 2 is pushed back into the cutting groove by the rotation of the limiting plate 9 on the rear side. The limiting ring 11 is used to restrict the cutting plate 2 in the cutting groove. The conveyor belt 3 continues to transport the mask and repeats the above cutting operation, thereby realizing the cyclic cutting processing of the mask.
