Description

TECHNICAL FIELD

[0001] The utility model relates to a bulletproof helmet piece weighing clamping pressure stick together and spread device and belongs to the bulletproof product production and processing technical field of equipment and tool class. BACKGROUND

[0002] At present, the production of bulletproof helmet is composed of n large pieces (integral cutting piece) and m small pieces (elliptical cutting piece added to strengthen the strength of the top of the helmet) on the piece head mould; the large and small pieces are all cut according to the size of impregnated aramid cloth, each large piece has six cutting seams, that is, divided into (A, B, C, D, E, F) six piece petals, and the whole is in the shape of a fan blade; in the production process, a plurality of large pieces are usually spread on the piece head mould, in order to make up for the thickness difference accumulated at the top and the lower part of the helmet, one small piece is needed at the top, and the large and small pieces are spread back and forth, and the last two layers must be large pieces to prevent the small piece from leaving marks on the inner and outer surfaces of the helmet.

[0003] In the traditional production process of bulletproof helmet, the piece spreading process has always been operated manually, generally one hand of the operator pulls the piece, the other hand uses a hot air gun to heat the piece, and then one petal is spread after another, and the fingers are easily scalded or the piece is damaged during work, the operation methods of each operator are different, and the helmets spread by different operators are various, some of the layers of the piece are too loose, some of the layers of the piece are not effectively bonded due to insufficient heating time of the hot air, some of the layers of the piece are deformed due to excessive pulling, the local thickness is too thick, the local material is insufficient, the piece is damaged during pressing, the local material is insufficient and wrinkles are generated, which greatly reduces the bulletproof performance and appearance quality of the helmet, and many defective products are generated, the bulletproof helmet material cannot be repaired and repaired, and only can be scrapped, causing great loss and waste. UTILITY MODEL CONTENTS

[0004] The utility model solves the technical problem of providing a bulletproof helmet piece weighing clamping pressure stick together and spread device which is fully automatic, prevents piece deformation and ensures that the number of layers and thickness of the piece of each section of the helmet are the same.

[0005] The utility model adopts the following technical scheme:

Then the upper right toothed pressure plate 312 and the upper left toothed plate 320 rotate 90° outward from their original positions.
