Breakage-proof perforating device for protective clothing

Abstract

The invention relates to the technical field of protective clothing processing, in particular to a breakage-proof perforating device for protective clothing. The device comprises a perforating processing table, wherein a concave perforating inner cavity is formed downward in the middle of the upper end face of the perforating processing table, a pressure bearing ring is arranged at the upper end of the perforating processing table, and side plates are symmetrically and vertically welded to the left side and the right side of the upper end face of the perforating processing table. The breakage-proof perforating device for protective clothing has the beneficial effects that by matching the pressing ring with the pressure bearing ring, textile silk threads around the perforating position of protective clothing are extruded and fixed, so that stretching of the silk threads in the perforating and stamping process is reduced, the stretching force between the silk threads is reduced, the deformation degree of the broken silk threads is reduced, and the perforating quality is greatly improved; by arranging a positioning needle, the perforating position is accurately positioned, and meanwhile, the perforating position is opened by inserting the positioning needle into the protective clothing, subsequent chambering and cutting are greatly facilitated, the perforating position precision is improved, the perforating and cutting convenience is improved, and the extrusion force is reduced.

Description

Technical field [0001] The present invention relates to the field of protective clothing processing, and in particular, a protective clothing anti-breaking perforation device. Background technique [0002] The type of protective clothing includes fire protection suit, industrial protective clothing, medical protective clothing, military protective clothing and special people using protective clothing. Protective clothing is mainly used in fire, military, ship, oil, chemical, painting, cleaning and disinfection, laboratory and other industries. [0003] The protective clothing is the same as the common clothes textile means, all of which are formed by using the wire to perform vertical and horizontal textile, and the silk textile of the protective clothing is more dense, and the tensile force between the wires is large, and therefore during the perforation process, due to the tool Cut extrusion, resulting in further stretching of the wire, the stretching force between the rear wir...

AI Technical Summary

Problems solved by technology

[0003] The protective clothing is the same as the common clothing weaving method. They are all criss-crossed with silk threads. However, the silk threads of the protective clothing are denser and the tensile force between the threads is larger. Cutting and extrusion will cause further stretching and deformation of the silk thread. After cutting, the tensile force between the thread disappears, which will cause the thread around the perforation to relax, which will easily cause damage to the textile structure of the protective clothing. However, the extrusion cutting of the existing perforation equipment, Not only will it increase the deformation of the protective clothing, but at the same time it is difficult to control the precision of the inner hole after cutting. Different tools are required for different hole diameters, resulting in increased production costs.

[0004] For this reason, an anti-damage perforation device for protective clothing is provided to solve the production cost and perforation quality problems of knives
