A kind of taking and feeding device of bulletproof helmet automatic laying machine

Abstract

The invention relates to a sheet taking and feeding device of an automatic sheet paver of a bulletproof helmet. The sheet taking and feeding device comprises a small sheet taking and feeding device and a large sheet taking and feeding device, wherein the small sheet taking and feeding device and the large sheet taking and feeding device are correspondingly arranged between first and second sheet taking and feeding linear sliding rails in a frame body; and the first sheet taking and feeding linear sliding rail and the second sheet taking and feeding linear sliding rail are arranged between two side edge frames of the frame body, and are parallel to each other. Large and small sheets are sucked through large and small sheet suckers by adopting vacuum to achieve the effects of stability and reliability; the sheet taking and feeding device is adopted to ensure that all sheets are accurately spaced by fixed angles and the paved sheets are uniform, so that the thicknesses and the performance of all points on the finished helmet are the same, and the product quality is improved; and the sheet taking and feeding 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 material sheet taking and feeding device 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 cannot be evenly spread out. The ...

[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
