Problems solved by technology

[0003] The existing polysifo film needs to be coiled after processing, so as to be stored, and in the final coiling process, if the previous machine fails, the film on the coiling roller will loosen, and when it is coiled again , will cause the film to overlap on the take-up roller, which will cause film quality problems due to extrusion, and after the film is taken up, the last section of the film has no stress point, and it is easy to take up unfavorably, and the film will deviate and cause film quality problems

Embodiment 1

[0027] see Figure 1-5 , a polytetrafluoroethylene film traction and winding device, including a base plate 11, a support plate 10 arranged on the base plate 11, and a take-up roller 2 installed on the support plate 10, the front side of the take-up roller 2 is provided with a guide Assemblies, the guide assembly is fixedly connected with a first slide bar 17, the first slide bar 17 is slidably connected with a first slide sleeve 18 fixedly connected with the bottom plate 11, the first slide sleeve 18 is provided with a The first chute 20, the first elastic member 19 is arranged between the bottom wall of the first chute 20 and the first slide bar 17, the first elastic member 19 is a spring, and the first slide bar 17 is fixedly connected with a first A fixed plate 21, the first fixed plate 21 is fixedly connected with the nesting rod 22, the head of the nesting rod 22 is conical and is fixedly connected with the first electromagnetic block 38, the first electromagnetic block ...

Embodiment 2

[0034] This embodiment is expanded on the basis of Embodiment 1. The outer side of the bottom plate 11 is covered with a protective shell 32. The protective shell 32 is provided with a through groove 33 for the film to enter and exit. The protective shell 32 is located on the rear side of the take-up roller 2. The opening and closing door 36 that can be opened and closed can avoid the disturbance of dust during the film winding process by setting the protective shell 32, and keep it clean and hygienic. By opening the opening and closing door 36, the coiled film can be manually removed. Roller 2, described protective case 32 is fixedly connected with the 3rd support 34 that is positioned at the lower end of channel 33, and the 3rd support 34 is installed with the 2nd guide roller 35, further guides film by the 2nd guide roller 35, avoids and passes through The sharp edges of the groove 33 are in contact, affecting the film quality.

Abstract

The invention relates to the field of polytetrafluoroethylene films, and discloses a polytetrafluoroethylene film pulling winding device. The device comprises a bottom plate, a supporting plate arranged on the bottom plate and a winding roller installed on the supporting plate, wherein a guide assembly is arranged on the front side of the winding roller, the guide assembly is fixedly connected with a first sliding rod, the first sliding rod is slidably connected with a first sliding sleeve fixedly connected with the bottom plate, the first sliding sleeve is provided with a first sliding groove matching the first sliding rod, a first elastic piece is arranged between the bottom wall of the first sliding groove and the first sliding rod, the first sliding rod is fixedly connected with a first fixing plate, the first fixing plate is fixedly connected with a nesting rod, the head of the nesting rod is conical and is fixedly connected with a first electromagnetic block, and a second electromagnetic block is arranged under the first electromagnetic block. The device is ingenious in structure, tension can be automatically adjusted, the quality problem caused by film winding is solved, and the quality problem caused by easy deviation after film winding is also solved.

Description

technical field [0001] The invention relates to the field of polytetrafluoroethylene films, in particular to a traction and winding device for polytetrafluoroethylene films. Background technique [0002] PTFE film is a microporous film produced by special processes such as premixing, extrusion, calendering, and biaxial stretching using PTFE dispersion resin. It is divided into clothing film, micro waterproof film, filter film, purification film membrane. [0003] The existing polysifo film needs to be coiled after processing, so as to be stored, and in the final coiling process, if the previous machine fails, the film on the coiling roll will loosen, and when it is coiled again , will cause the film to overlap on the take-up roller, which will cause film quality problems due to extrusion, and after the film is taken up, the last section of the film has no stress point, and it is easy to take up unfavorably, and the film will deviate and cause film quality problems .
