Full-automatic non-woven fabric shoe cover overlock machine

Abstract

The invention discloses a full-automatic non-woven fabric shoe cover overlock machine. A roll non-woven fabric shoe cover raw material is subjected to processes of automatic feeding, folding, tailoring, sewing, discharging and the like by the machine, and automatic production of a shoe cover is completed; the sewing process comprises steps as follows: sewing of a shoe cover opening, folding, sewing of a shoe sole opening, tailoring and sewing of a circular arc edge; straight line and circular arc combined guide tracks are designed, the production time of a single shoe cover is shorter than or equal to 3 seconds; the overlock machine commonly used in the market is used for sewing an elastic band onto the shoe cover; a folding mechanism is always in a horizontal state in the folding process and matched with a conveying speed; the semi-circular arc edge is sewn through self-rotation of a clamp, and the circular arc is at the front end of the made shoe cover and is attractive and fit for a foot; a special tailoring mechanism is designed, and fusing is not required; non-woven fabric coated with anti-slip coating can be used, an anti-slip strip is not required to be pressed, and a product is anti-static, breathable and wear-resisting; and the machine occupies little space, the stations are smoothly connected, a small long strip is not required to be folded for wrapping the elastic band, the noise is low, and the folding mechanism is simple, flexible and stable in folding and cannot tear the raw material.

Description

technical field [0001] The invention relates to a fully automatic non-woven shoe cover sewing machine, in particular to a fully automatic sewing forming and production device for non-woven material shoe covers, which belongs to the technical field of textile machinery in the textile industry. Background technique [0002] Each step of the non-woven shoe cover of existing manual sewing needs manual operation of workers, and the steps are as attached figure 1 As shown, the operation process is as follows: [0003] (1) Cutting width: Use large-scale cutting equipment to cut non-woven fabric raw materials tens of meters long and nearly two meters wide into strips with a width of 170 mm, and then roll them into rolls; [0004] (2) Cut into sections: Cut the strip-shaped non-woven fabric cut in the previous step into 720 mm long sections, and then fold them in half; [0005] (3) Sewing: After the worker folds the sectioned fabric in half, the worker pushes the folded fabric into...

Problems solved by technology

[0006] According to statistics, it is found that only the sewing stage in the process of making shoe covers takes nearly 10-15 seconds for skilled workers, and more than 20 seconds for general workers, which is inefficient and tiring.

[0007] Chinese invention patent "Disposable shoe cover automatic production machine" (application number: 200510029967.3), utility model patent "a shoe cover manufacturing machine" (application number: 200320115953.X), "a shoe cover processing machine" (application number : 200620012295.5), "Shoe Cover Processing Machine" (Application No.: 01203735.4) and "Waterproof and Dustproof Shoe Cover Manufacturing Machine" (Application No.: 98207730.0), etc., among the disclosed contents, the deficiencies mainly include: The linear workbench takes up a lot of space; the folding process has a large turning angle, which is easy to pull and damage the plastic film, and the entire shoe cover production process is too long; use the elastic band on the edge bander to fold small strips The elastic band is wrapped on the side of the membrane material, involving many mechanisms; the shoe cover made is straight and rectangular, which is not beautiful to wear; or the hot-melt joint is easily damaged, the fusion-shear joint is easily damaged, or the raw material is Plastic film, easy to generate static electricity when used, easy to damage and airtight and other disadvantages
