Shearing device for door curtain production

Abstract

One or more embodiments of the invention provide a shearing device for door curtain production, comprising: a shearing conveying table, the left and right sides of which are provided with guide sliding sleeves; a pressing shearing seat arranged above the shearing conveying table; a fixed shearing seat arranged on the opposite side of the shearing conveying table; strip shearing knives arranged on the inner side of an embedding mounting groove in an embedded manner; and a horizontal top plate arranged on the rear side of the strip shearing knife. According to the shearing device for door curtain production, the pressing shearing seat drives the strip shearing knife and a strip shearing knife arranged on the fixed shearing seat to move in a staggered mode, then a screen door between the strip shearing knives is pressed and cut, the strip shearing knives are arranged in the embedding mounting groove in embedded and sliding modes and can be pushed by the horizontal top plate to move outwards, and then the outer side faces of the strip-shaped shear knives are polished through friction abrasive belts correspondingly arranged on the pressing shearing seat and the fixed shearing seat, so that the edge sharpness of the strip shearing knives is continuously kept, the shearing quality is kept, and the overall production quality is improved.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of production of screen door curtains, in particular to a shearing device for production of door curtains. Background technique [0002] The screen door curtain is a kind of screen window installed on the door. Its main function is to prevent mosquitoes. The screen door is widely used in various places such as families, restaurants, hotels, offices, and hospitals. At the same time, the screen door is closed with a good screen window It is the first choice for modern households to get rid of insecticides and mosquito coils. Screen doors are mainly divided into soft screen doors and hard screen doors. The center is closed so that it can be used, so the structure of the soft screen door is simple and the cost is low, the installation and use are more convenient, and the scope of application is also wider. [0003] The applicant found that when producing screen door curtains, it i...

Problems solved by technology

[0003] The applicant found that when producing screen door curtains, it is often necessary to divide the gauze net into multiple equal-length gauze segments, so that the edge sealing of the equal-length gauze segments can be processed into finished screen doors. When making a screen, the rotary blade is generally used to cut the screen door, but the cutting edge of the rotary blade is not neat, and it is easy to produce edge broken and dew lines, etc., and the blade pressing type shearing process can improve the neatness of the cutting edge, However, the corresponding blades need to be kept sharp at the edges, and during the continuous processing, the wear of the blades is serious, which leads to the inability of the blades to cut the gauze neatly and requires frequent replacement, resulting in a decrease in overall production efficiency , and after the gauze is cut, the edge of the gauze still has the situation of running and breaking due to the disconnection of the wire, which leads to a decrease in the uniformity of the cutting edge, which in turn leads to a decrease in production quality
