Sheet taking/feeding and arranging device of automatic sheet paver of bulletproof helmet

Abstract

The invention relates to a sheet taking / feeding and arranging device of an automatic sheet paver of a bulletproof helmet. A sheet taking / feeding device comprises a small sheet taking / feeding device and a large sheet taking / feeding device; an arranging means is arranged at the lower end of the large sheet taking / feeding device; and a cloth folding and gathering device is arranged on the large sheet taking / feeding device. Large and small sheets are sucked in sequence through large and small sheet suckers by vacuum, so that the stability and the reliability are achieved; the cloth folding and gathering device enables all large sheets to be accurately gathered into fixed shapes through pull wires when being moved rightly above a lower mold body, so that the accuracy and the reliability are achieved; the arranging means guarantees the consistency of upper and lower positions of the gathered sheets at adjacent two sides of all shearing mouths, and reduces the frictional resistance of an overlapped area to enable the mouth-shorn sheets to be overlapped more quickly and more accurately; and the sheet taking / feeding and arranging 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 an automatic sheet laying machine for bulletproof helmets, which takes and sends material sheets and a device for smoothing them out. 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 canno...

[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
