A shearing device for door curtain production

Abstract

One or more embodiments of this specification provide a shearing device for door curtain production, including: a shearing conveying platform, and guide sliding sleeves are arranged on the left and right sides of the shearing conveying platform; above the shearing conveyor table; the fixed shearing seat is arranged on the opposite side of the shearing conveyor table; the strip shearing knife is fitted inside the fitting installation groove; the horizontal top plate is arranged on the The rear side of the strip shears. In the present invention, the strip-shaped shearing knife and the strip-shaped shearing knife set on the fixed shearing seat are driven to interlock and move by pressing the shearing seat, and then the screen door in between is pressed and cut, and the strip-shaped shearing knife fits The slide is set in the fitting installation groove, and can be pushed to the outside by the horizontal top plate, and then the outer surface of the strip shearing knife is polished by the corresponding friction abrasive belts on the pressing shearing seat and the fixed shearing seat. To maintain its edge sharpness continuously, so as to maintain the cut quality and improve the overall production quality.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of screen door curtain production, and in particular, to a shearing device for door curtain production. 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 homes, restaurants, hotels, offices, hospitals, etc. 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. Soft screen doors are generally composed of two pieces of gauze, which can be installed on a suitable door frame and held by magnet buckles. Therefore, the soft screen door has a simple structure, low cost, convenient installation and use, and wider application range. [0003] The applicant has found that when producing screen door curtains, it is often n...

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
