Large material sheet fetching and delivering device and mould of bulletproof helmet automatic sheet paving machine

Abstract

The invention relates to a large material sheet fetching and delivering device and a mould of a bulletproof helmet automatic sheet paving machine. The large material sheet fetching and delivering device is arranged between a first material sheet delivering linear slide rail and a second material sheet delivering linear slide rail. The mould comprises an upper mould, a driving device of the upper mould, a lower mould, and a driving device of the lower mould. The large material sheets are absorbed by a large material sheet sucking disc in sequence through the vacuum effect, and the adsorption is stable and reliable. The upper mould is provided with a heating device, the temperature is automatically controlled, the temperature rising is fast and uniform, and the heating device can heat the material sheets so as to soften the material sheets, while the contraction and expansion between the material sheets are not affected at the same time. The lower mould and the driving device of the lower mould can guarantee that the sheets be evenly paved. The large material sheet fetching and delivering device and the mould have the advantages of high sheet paving quality, convenient operation, and largely-improved work efficiency in the bulletproof helmet sheet paving operation.

Description

technical field [0001] The invention relates to a device for taking and delivering large material pieces and a mold of an automatic 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 evenl...

[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
