A device for taking and feeding material sheets and folding cloth in half of an automatic sheet laying machine for bulletproof helmets

Abstract

The invention relates to a sheet taking / feeding and cloth folding / gathering device of an automatic sheet paver of a bulletproof helmet. The sheet taking / feeding device comprises a small sheet taking / feeding device and a large sheet taking / feeding device; the cloth folding / gathering device is arranged on the large sheet taking / feeding device; and the small sheet taking / feeding device and the large sheet taking / feeding device are correspondingly arranged between first and second sheet taking / feeding linear sliding rails in a frame body of the automatic sheet paver of the bulletproof helmet. Large and small sheets are sucked in sequence through large and small sheet suckers by adopting vacuum, so that the stability and the reliability are achieved; the cloth folding / gathering device enables all large sheets to be accurately gathered to fixed shapes through pull wires when being moved rightly above a lower mold body, so that the accuracy and the reliability are achieved; and the sheet taking / feeding and cloth folding / gathering device is used for performing the bulletproof helmet sheet paving operation, so that the sheet paving quality is high, the operation is convenient, and the working efficiency is largely improved.

Description

technical field [0001] The invention relates to a device for taking and feeding material sheets and folding cloth in half of an automatic sheet-laying machine for bulletproof helmets. Background technique [0002] At present, the production of bulletproof helmets for soldiers or armed police consists of n large pieces (the overall piece is referred to as the large piece) and m small pieces (the oblong pieces added to strengthen the strength of the top of the helmet are referred to as small pieces) Laying sheet composition, large and small pieces are cut from aramid cloth according to size, each large piece has four cutting seams evenly, the whole is in the shape of a fan blade, 4 pieces of large pieces are laid in turn during the production process and then Laying 1 piece of small material, the laying process is all manual spreading, which requires a lot of labor, and such manual laying cannot ensure that each material is accurately spaced at a fixed angle, and the seams can...

[0002] At present, the production of bulletproof helmets for soldiers or armed police consists of n large pieces (the overall piece is referred to as the large piece) and m small pieces (the oblong pieces added to strengthen the strength of the top of the helmet are referred to as small pieces) Laying sheet composition, large and small pieces are cut from aramid cloth according to size, each large piece has four cutting seams evenly, the whole is in the shape of a fan blade, 4 pieces of large pieces are laid in turn during the production process and then Laying 1 piece of small material, the laying process is all manual spreading, which requires a lot of labor, and such manual laying cannot ensure that each material is accurately spaced at a fixed angle, and the seams cannot be evenly spread out. The unevenness between the paved materials will lead to inconsistent thickness of each point on the finished helmet, resulting in inconsistent performance of various parts of the helmet bulletproof, affecting product quality, time-consuming and labor-intensive, and low work efficiency
