TPU film fixed-width cutting device

Abstract

The invention discloses a TPU film fixed-width cutting device, and belongs to the field of cutting devices. The TPU film fixed-width cutting device comprises a cutting table, wherein the front end and the rear end of the left side of the upper end of the cutting table are fixedly connected with convex blocks correspondingly, the upper ends of the convex blocks are fixedly connected with pressing rods, the pressing rods are provided with sliding grooves, anti-falling rods are connected to the interiors of the sliding grooves in a sliding mode, the right sides of the anti-falling rods are fixedly connected with a front baffle and a rear baffle correspondingly, and one sides of the front baffle and the rear baffle are fixedly connected with pressing blocks correspondingly. According to the TPU film fixed-width cutting device, the front baffle and the rear baffle are arranged on the front side and the rear side of the upper end of the cutting table correspondingly, the front baffle and the rear baffle are limited and fixed through the connection of threaded rods and fixing seats, so that TPU films with different widths can be conveniently limited and fixed in the front-back direction; and the upper ends of the TPU films are limited and fixed in the up-down direction through the pressing rods and the pressing blocks correspondingly, so that the front-back and up-down limiting and fixing of the TPU films are increased, and the circumstance that the TPU films are inclined and damaged due to the fact that the TPU films move in all directions during cutting is avoided.

Description

technical field [0001] The invention relates to the field of cutting devices, more specifically, to a TPU film fixed-width cutting device. Background technique [0002] TPU, thermoplastic TPU elastomer, is made of MDI containing NCO functional groups and POLYOL and 1.4BG containing OH functional groups, which are made by extrusion and mixing. Due to good elasticity, good physical properties and various mechanical strengths, Therefore, it is widely used in processing methods such as injection, extrusion, calendering and dissolving into solution resins. It is a plastic material often used by plastic processing industry, and its products cover the range of industrial applications and civilian necessities. [0003] At present, the fixed-width limiting device in the fixed-width cutting device of TPU film is not stable when limiting the position, and it is not easy to perform fixed-width limiting for TPU films of different widths, which leads to the phenomenon of beveled edges on ...

AI Technical Summary

Problems solved by technology

[0003] At present, the fixed-width limiting device in the fixed-width cutting device of TPU film is not stable when limiting the position, and it is not easy to perform fixed-width limiting for TPU films of different widths, which leads to the phenomenon of beveled edges on the cut TPU film, thus giving It brings a lot of trouble to use, and at the same time, most of the TPU film is cut by manual winding, which is not only inconvenient, but also the limit is not stable, and the manual labor force is also increased.
