Adjustable fabric punching device

Abstract

The invention provides an adjustable fabric punching device and belongs to the technical field of fabric processing. The adjustable fabric punching device comprises a turntable, a lever and an adjusting screw rod. The turntable is rotationally arranged on an upper supporting ring of an upper disc seat and a lower supporting ring of a lower disc seat. The lever is clamped into a lever mounting groove of the turntable. The adjusting screw rod is in threaded connection with an adjusting screw rod nut. A left pin shaft at the left end of the lever is inserted into a lower U-shaped groove in the lower end of a punching lower supporting plate supporting frame. A punching lower supporting plate is horizontally arranged at the upper end of the punching lower supporting plate supporting frame. Punching nails are uniformly arranged at the upper end of the punching lower supporting plate. Punching grooves are uniformly formed in a punching upper supporting plate. A driving rod is arranged on a driving rod guide seat in the form of sliding up and down. A lower pin shaft at the lower end of the driving rod is inserted into a right U-shaped groove in the right end of the lever. A driving rod roller is rotationally arranged at the upper end of the driving rod through a driving rod roller supporting shaft. A driving cam is arranged at one end of a driving shaft. According to the adjustable fabric punching device, the stroke of the punching lower supporting plate is adjustable, and the punching processing of fabrics with different thicknesses can be realized.

Description

technical field [0001] The invention relates to the technical field of fabric processing, in particular to an adjustable fabric punching device. Background technique [0002] There are many types of fabrics, including woven fabrics, knitted fabrics, etc. Woven fabrics, also known as woven fabrics, are fabrics formed by interweaving warp and weft yarns vertically. There are three basic weaves: plain weave, twill weave, and satin weave. It is composed of various structures, mainly chiffon, Oxford cloth, denim, twill, flannel, damask and so on. Knitted fabrics, knitted fabrics use knitting needles to form yarns or filaments into coils, and then put the coils together. Due to the coil structure of knitted fabrics, there is more yarn stored per unit length, so most of them have good elasticity. . Knitted fabrics are divided into single-sided and double-sided, mainly jersey, velvet, bird's eye cloth, mesh cloth and so on. Suede is a common fabric. In the cloth market, suede ha...

AI Technical Summary

Problems solved by technology

However, the fabric punching machine with this structure is very inefficient in processing the air holes of the suede fabric.

At present, the fabric punching device with the highest efficiency is to use punching needles to realize the punching process on the fabric. It cannot be applied to fabrics of various thicknesses, which has great limitations
