Description

Technical Field

[0001] The invention belongs to the technical field of masks, and in particular relates to a mask body manufacturing device used in mask production. Background Art

[0002] At present, the flat masks on the market are mainly made of non-woven fabrics, which are mainly made by directional or random arrangement of textile short fibers or filaments to form a fiber mesh structure, and then reinforced by mechanical, thermal bonding or chemical methods. When producing flat masks, the non-woven fabric needs to be cut into rectangular mask shapes by a cutting roller of a cutting mechanism. When the cutting roller on the existing mask production equipment rotates, it needs to cut about 50 times per minute. However, since the fibers of the cut part of the non-woven fabric will be loose after cutting, these fiber impurities are easily adsorbed on the blade of the cutting roller, and the fibers and floating hair on the surface, as well as the dust in the air contaminated by the surface of the cloth during transportation, will be adsorbed on the surface of the cutting roller. If it is not cleaned, long-term squeezing will easily have a serious impact on the hygiene of the mask. When cleaning the cutting roller and the conveying roller, the existing cleaning device mainly uses dust suction to remove impurities and dust attached to the surface of the cutting roller and the conveying roller. When this impurity removal method is used for a cutting roller equipped with a cutting knife, the air suction port cannot be close to the cutting roller, resulting in a general impurity removal effect of the dust removal fan. In addition, the dust removal fan needs to work continuously and uninterruptedly, consuming a lot of electricity, which will increase production costs. Summary of the invention

[0003] In view of the above problems, the present invention discloses a mask body manufacturing device used in mask production, which can effectively clean impurities and dust adsorbed on the cutting roller when producing masks.

[0004] The specific technical solutions are as follows:

[0007] Furthermore, the height of the cleaning sleeve is lower than the height of the cutting blade.

[0008] Furthermore, the sum of the lengths of the two groups of gear teeth is half of the inner diameter of the rotating seat.

[0009] Furthermore, the length of the cutting roller is greater than the length of the cutting pad roller.

[0010] Furthermore, when the cutting blade rotates to the bottom of the cutting roller, the cleaning sleeve moves to the positions at both ends of the cutting roller.

[0011] Furthermore, when two adjacent second gears cooperate with a set of gear teeth in the rotating seat and complete one rotation, the cleaning sleeve performs a reciprocating motion on the cutting roller.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) The present invention uses a cleaning sleeve to reciprocate while rotating with the cutting roller, thereby cleaning the surface of the cutting roller and the cutting blade, and can effectively remove fiber impurities adhering to the surface, thereby achieving a better cleaning effect.

[0014] (2) In the present invention, the driving motor drives the cutting roller to rotate, and the second gears at one end of the first screw rod and the second screw rod respectively rotate in cooperation with the gear teeth on the rotating seat, so that the cleaning sleeve can reciprocate on the rotating cutting roller under the repeated rotation of the first screw rod and the second screw rod, thereby achieving a cleaning effect.

The thread is provided with two symmetrically arranged first screw rods 415 and two symmetrically arranged second screw rods 416, the thread direction on the first screw rod 415 is opposite to the thread direction on the second screw rod 416, and the connecting line between the two first screw rods 415 is perpendicular to the connecting line between the two second screw rods 416, one end of the first screw rod 415 and the second screw rod 416 both pass through the positioning seat 412 at one end of the cutting roller 41 and are respectively provided with a first gear 4151, the four first gears 4151 are symmetrically distributed in pairs, and two adjacent first gears 4151 are meshed and connected with each other, the other ends of the first screw rod 415 and the second screw rod 416 both pass through the positioning seat 412 at the other end of the cutting roller 41 and are respectively provided with a second gear 4152, the first screw rod 415 and the second screw rod 416 are both rotatably connected to the two positioning seats 412, the four second gears 4152 are respectively arranged to fit the inner wall of the rotating seat 101, and the second gear 4152 is meshed and connected with the gear teeth 1011.

[0030] Working principle:

[0031] During operation, the driving motor 2 drives the guide roller group 3, the cutting roller group 4 and the leveling roller group 5 to operate through the belt. While conveying the mask cloth, the cutting blade 411 on the cutting roller 41 continuously rotates to cut the mask cloth; while the cutting roller 41 rotates itself, it drives the two first screw rods 415 and the two second screw rods 416 to rotate along the axial direction of the cutting roller 41, so that the four second gears 4152 at one end of the first screw rod 415 and the second screw rod 416 respectively rotate in sequence with the gear teeth 1011 on the rotating seat 101. When the two first screw rods 415 rotate in cooperation with the gear teeth 1011, the two first gears 4151 drive the adjacent first gears 4 151 rotates, thereby driving the second screw rod 416 to rotate in the opposite direction. Since the thread directions of the first screw rod 415 and the second screw rod 416 are opposite, the cleaning sleeve 414 moves toward one end of the cutting roller 41 under the action of the first screw rod 415 and the second screw rod 416 and cleans. When the cleaning sleeve 414 moves to the edge, the second gears 4152 on the two first screw rods 415 are no longer meshed with the gear teeth 1011, and the second gears 4152 on the two second screw rods 416 begin to mesh with the gear teeth 1011, and repeat the above movement principle, so that the cleaning sleeve 414 moves to the other end of the cutting roller 41 and cleans, thereby performing a cyclic reciprocating motion.
