Full-automatic production equipment and process for vertical folding mask

Abstract

The invention discloses full-automatic mask production equipment and process for a vertical folding mask. The equipment comprises a feeding module, a nose bridge line imbedding module, a knurling module, an edge cutting module, an ear line welding module, an edge sealing module and a waste traction module which are arranged in sequence. The edge cutting module is adjacently arranged at a downstream station of the knurling module, a mask base body formed by compounding multiple layers of cloth is knurled by the knurling module and then enters the edge cutting module in a flat state, a mask bodycut by an edge cutting shaft of the edge cutting module is embedded into the mask base body and is forwards conveyed to a subsequent station along with the mask base body, the ear wire welding moduleis used for welding ear wires to the cut mask body, and the edge sealing module is used for folding the mask body in half and sealing the edge of the mask body, and the equipment further comprises apunching module and a positioning module. The equipment has the advantages of being high in cutting precision, small in debugging difficulty, accurate in positioning, small in size, flexible in station arrangement and the like.

Description

technical field [0001] The invention relates to a mask production equipment and process, in particular to a vertical folding mask fully automatic production equipment and process. Background technique [0002] At present, the production of vertical folding masks (such as KN95 masks) mainly includes semi-automation and full automation. The machine is used to combine multi-layer fabrics by ultrasonic method, and put them into the bridge of the nose, and then perform knurling and edge trimming to obtain a sheet-shaped intermediate product; then manually transfer to the ear wire welding module for ear wire welding , and finally carry out edge processing. Semi-automated vertical folding mask production equipment has disadvantages such as low efficiency, high labor costs, and large equipment footprint. [0003] The fully automated vertical folding mask production equipment overcomes the above-mentioned shortcomings of semi-automatic equipment, and realizes the fully automated pr...

AI Technical Summary

Problems solved by technology

[0004] 1. When cutting the edge of the vertical folding mask, it needs to be cut along the edge line formed during knurling and the edge line formed during edge sealing. In the existing fully automated vertical folding mask production equipment, the knurling worker The position is located at the starting position of the production line, while the trimming station is located at the end of the production line. Due to the distance between the two stations and the fact that the mask matrix made of cloth has tensile deformation characteristics, the edge trimming station It is very difficult to cut evenly along the outside of the edge line formed during knurling, and usually requires a long period of debugging, which makes it difficult to put the equipment into use quickly, and errors may occur during use or after the fabric is replaced, It needs to be re-debugged, seriously affecting production efficiency

[0005] 2. The existing fully automated vertical folding mask production equipment performs trimming after folding the mask base in half, and the accuracy of the half-folding also affects the accuracy of the trimming, thereby further increasing the difficulty of precise edge trimming; and, after folding the mask base in half Double the thickness, slipping or incomplete cutting may occur during cutting, affecting product quality and production speed

[0006] 3. In the existing fully automated production process of vertical folding masks, since the mask body and the mask base are separated at the end, the processes of folding, sealing and trimming of the mask base must be carried out sequentially in the way of flow operation , the two stations of edge banding and edge trimming can only be set at the front and rear of a single station, and multi-station settings cannot be made according to needs

[0007] 4. In the existing fully automated vertical folding mask equipment, the processes of folding, sealing and trimming the mask base must be carried out sequentially in the way of assembly line operation, especially the half-folding process of the mask base, which needs to be gradually changed. The docking method is carried out, and the completion of half-folding requires a long conveying distance, which makes the length of the entire production equipment large.

[0008] 5. In the existing fully automated vertical folding mask production equipment, the mask substrate after folding in half is in an upright state, and the mask substrate in the upright state is sealed and trimmed during the transportation process, which is difficult to locate and also leads to edge sealing and cutting. The accuracy of the edge is difficult to guarantee
