A kind of bulletproof helmet precise automatic spreader

Abstract

The invention relates to a precise and automatic sheet paver of a bulletproof helmet. The precise and automatic sheet paver comprises a frame body, a working platform arranged at one side of the middle in the frame body and provided with a long through hole, a precise large sheet picking device arranged at one side of the working platform, first and second sheet taking and feeding linear sliding rails arranged between two side edge frames of the frame body and parallel to each other, an upper mold linear sliding rail arranged on the lower part of an upper cross beam of the frame body, large and small sheet taking and feeding devices arranged between the first and second sheet taking and feeding linear sliding rails and corresponding to each other, an upper mold arranged on the upper mold linear sliding rail and a driving device thereof, and a lower mold arranged below the long through hole of the working platform and a driving device thereof, wherein a cloth folding and gathering device and a large sheet cloth folding and gathering part overlaying order arrangement device are arranged on the large sheet taking and feeding device. The precise and automatic sheet paver 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 precise 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 evenly spread out. The unevenness between the paved materials leads ...

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
