Independent cutter of curtain hole punch

Abstract

The invention discloses an independent cutter of a curtain hole punch. The independent cutter comprises a main shaft and a blade, and further comprises a hollow outer sleeve with the lower end open and a cloth pressing cylinder coaxially sleeved with the outer sleeve. The lower end of the main shaft penetrates through the cloth pressing cylinder, the cloth pressing cylinder is installed on the main shaft through the lower end of the main shaft, and the upper end of the outer sleeve is fixedly installed on the main shaft. An elastic device for supplying elasticity when the cloth pressing cylinder moves up and down is arranged between the upper end of the cloth pressing cylinder and the upper wall inside the outer sleeve. The blade is a cylindrical blade arranged around the outer sleeve. The upper end of the blade is connected with the lower end of the outer sleeve, and the lower end of the blade is a non-plane-port-shaped cutting edge. In the non-working state, the cloth pressing end of the cloth pressing cylinder extends out of the lower end of the blade. The independent cutter of the curtain hole punch has the advantages that the structure is compact and simple, the blade does not need to be replaced or dismounted or mounted, the cutting edge is sharp, time and labor are saved, the curtain hole punching quality is good, and the independent cutter can be widely popularized and used.

Description

technical field [0001] The invention relates to parts of a curtain punching machine, in particular to an independent cutter of the curtain punching machine. Background technique [0002] When people are making curtains, in order to facilitate the curtains to be hung on the curtain rods, holes need to be punched at the top of the curtains. With the advancement of science and technology, people have invented and designed various curtain punching machines. By using the curtain punching machine to replace the most primitive manual punching work, not only the efficiency of curtain punching is greatly improved, but also time is saved. Regardless of whether it is a mechanical curtain punching machine or an electric curtain punching machine, the cutter is one of its essential key components. The cutter that the curtain punching machine of prior art uses has following shortcoming: [0003] 1. The knives of the existing electric curtain punching machines are generally fixedly connec...

AI Technical Summary

Problems solved by technology

[0003] 1. The knives of the existing electric curtain punching machines are generally fixedly connected to the main machine directly. When the knives are severely worn or different types of knives need to be replaced, it is difficult to disassemble and replace them;

[0004] 2. The blade of the existing curtain punching machine is a flat knife. Because the contact surface between the blade and the cloth is too large, the resistance is large when punching, the knife edge is easy to heat, and the cutting speed is slow. Cloth scraps easily enter the cutter body and are difficult to remove; or the blade is flat and has a cutting tip at the lower end of the blade, the blade is easily damaged, and it is time-consuming and laborious to disassemble and replace frequently
