Small sheet taking/feeding device and mold of automatic sheet paver of bulletproof helmet

Abstract

The invention relates to a small sheet taking / feeding device and a mold of an automatic sheet paver of a bulletproof helmet. The small sheet taking / feeding device is arranged between first and second sheet taking / feeding linear sliding rails of a frame body; and the mold comprises an upper mold arranged in the frame body of the automatic sheet paver of the bulletproof helmet and a driving device thereof, and a lower mold and a driving device thereof corresponding to the lower mold and the driving device thereof. The small sheet taking / feeding device sucks small sheets through small sheet suckers by vacuum to achieve the stability and the reliability; as a heating device is arranged on the upper mold, the temperature is automatically controlled and quickly and evenly risen, the sheets are heated for softening when being pressed and temporarily and slightly bonded, and the sheet paving uniformity is guaranteed; and the small sheet taking / feeding device and the mold are 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 delivering small pieces of an automatic sheet-laying machine for bulletproof helmets and a mold. 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 s...

[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
