Thin film leveling guide roller mechanism

Abstract

The invention relates to the field of thin film processing, and particularly discloses a thin film leveling guide roller mechanism. The thin film leveling guide roller mechanism comprises limiting mechanisms, a guide rail roller, a leveling mechanism and a driving mechanism. The limiting mechanisms are coaxially arranged at the two ends of the guide rail roller and are further fixed to a roller distribution rack, and limiting guide rail grooves used for restraining movement of the leveling mechanism are formed in the corresponding limiting mechanisms. The leveling mechanism is arranged at the outer side of the guide rail roller. Guide rail grooves are symmetrically formed in the outer circumferential face of the guide rail roller. The leveling mechanism comprises leveling sliding blocks and push-and-pull mechanisms. Each push-and-pull mechanism is arranged at one end of the corresponding leveling sliding block. The leveling sliding blocks are provided with guide rails, and the leveling mechanism can slide relatively on the surface of the guide rail roller through sliding fit of the guide rails and the guide rail grooves. The leveling mechanism rotates synchronously along with the guide rail roller. The push-and-pull mechanisms make relative circumferential slide in the corresponding limiting guide rail grooves, the leveling sliding blocks are driven to slide on the guide roller in a reciprocating mode, and accordingly thin films can be expanded and unwrinkled.

Description

technical field [0001] The invention relates to the field of film processing, in particular to a film leveling guide roller mechanism. Background technique [0002] PE film and polyethylene film are usually used for sheet coating, and PE film and polyethylene film are usually produced continuously at high temperature. The temperature drop process will occur during the forming process of the film, and the surface temperature will drop during the film transmission process A certain amount of shrinkage will cause the film to be uneven and wrinkled, which will affect the production quality and production efficiency of the film. Therefore, it is necessary to expand the film in time to remove wrinkles. [0003] Application No. 201420611551.7 discloses a film cooling roller, which includes a roller and a cooling pipe. There are discharge holes at both ends of the roller. The roller is rotatably connected to the cooling pipe. A spiral flow channel is formed between the cooling pipe...

AI Technical Summary

Problems solved by technology

[0004] However, this invention can only cool down the rollers to eliminate the temperature difference, reduce the cooling shrinkage rate of the film, and alleviate the wrinkling phenomenon of the film, but cannot completely solve the problem of wrinkling and shrinkage, and cannot achieve wrinkle removal and smoothing of the film that has already wrinkled and shrunk.
