Planar mask production line

Abstract

The invention discloses a planar mask production line which comprises a cloth roll feeding module, a wrinkle forming module, a nose line feeding module, a welding module, a slicing module and a powersource. The cloth roll feeding module comprises a plurality of cloth rolls, and the cloth rolls are rotationally connected to a rack; the wrinkle forming module comprises a mounting frame and a plurality of groups of wrinkle assemblies arranged on the mounting frame; the welding module comprises a welding roller, a welding table and ultrasonic equipment; the slicing module comprises a slicing roller and a feeding roller, a slicing knife extending in the axial direction is arranged on the slicing roller, and a cutting edge of the slicing knife is tangent to the circumferential surface of the feeding roller; the welding roller and the slicing roller are connected with the power source through a first transmission mechanism. Full-automatic production of the planar masks is achieved, the feeding precision of the nose bridge line is high, and the machining quality of the planar masks can be improved.

Description

Technical field [0001] The invention relates to a production equipment for medical protective articles, in particular to a flat mask production line. Background technique [0002] Masks are important health protection materials, and wearing masks plays an important role in preventing virus infection. In the production process of flat masks, it specifically includes the feeding and welding of the bridge of the nose, the welding of the mask, the cutting of the mask, and the cutting of the mask. [0003] In the prior art, during the feeding and welding process of the nose bridge line, the nose bridge line generally starts from the material roll, is driven by the conveying device, and moves to the welding position of the nose bridge line of the mask fabric, and then the cutter on the conveying device will The nose bridge line is cut, so that the nose bridge line falls on the position where the mask fabric is to be welded; then under the pull of the mask fabric, the separate nose bridg...

Problems solved by technology

[0004] In the above-mentioned conveying process of the bridge of the nose, when the bridge of the nose is cut off, the active conveying power is completely lost, and the bridge of the nose can only be driven to move synchronously during the movement of the mask fabric, resulting in a tendency for the nose bridge and the fabric of the mask to move relatively Move; when the mask cloth moves to the welding station, the bridge of the nose line has shifted back a certain distance and cannot be aligned with the middle part of the welding position of the mask cloth, thereby reducing the yield of the final mask; when the user uses the mask, the mask The bridge of the nose cannot match the bridge of the user's nose or there is a certain offset, which will affect the use effect

[0005] In addition, in the production process, the power transmission mechanism of the equipment has certain transmission errors and other factors. After a period of continuous production and processing, the delivery progress of the nose bridge line will lag behind that of the mask cloth, thus affecting the nose bridge line. The position on the mask cloth

In order to solve the above problems, the traditional method is to manually disassemble the power source and related transmission mechanism, and then adjust the transmission mechanism of the nose bridge line and the corresponding transmission mechanism, so as to maintain the transmission progress of the nose bridge line and the transmission progress of the mask cloth. Consistent, but such an adjustment requires the disassembly of the power source and related transmission mechanisms. The operation is troublesome, the adjustment efficiency is low, and the production progress is seriously affected. At the same time, frequent disassembly and assembly of related parts will have a certain impact on the service life of the production equipment. Impact
