Circulation system with two tracks of internal track and external track

Abstract

The invention discloses a circulation system with two tracks of an internal track and an external track. The circulation system comprises a film inlet track, a film collecting track, a drying room inner track and a drying room outer track; an inner side chain guide groove is formed in the inner side of a film inlet guide plate, and an outer side chain guide groove is formed in the outer side of the film inlet guide plate; the drying room inner track is arranged inside a drying room, the drying room inner track comprises two symmetrically-arranged inner track guide plates, and the two inner track guide plates are separated from each other gradually from the parallel arrangement to the two sides, the distance is gradually increased and then parallel arrangement is achieved, and inner chain guide grooves are formed in the inner track guide plates; a film collecting chain guide groove is formed in the film collecting guide plate, and a driving chain wheel is arranged at the rightmost end of the film collecting guide plate; and the drying room outer track comprises two outer track guide plates which are symmetrically arranged outside the drying room, and outer chain guide grooves are formed in the outer track guide plates. According to the circulation system, the internal track and the external track are arranged inside and outside the drying room respectively so that the temperature of the chain on the outer track and the temperature of a film clamp arranged on the chain can be reduced, so that the problem that a film at a film inlet is burned and damaged because the temperature of the film clamp is too high is solved.

Description

technical field [0001] The invention relates to a film-feeding track, in particular to an inner and outer double track circulation system. Background technique [0002] In the field of special film preparation, the preparation of ultra-thin films is generally made by stretching thicker films after being clamped and transported by rails. The rails are generally divided into inner rails and outer rails, and the film clips are transported through the inner rails. Carry out mold drawing, and send back to the starting position through the outer track to enter the film. The inner track and the outer track in the prior art are set in the drying room. After the film is collected, the film clamp returns from the outer track to the film feed track When the film is clamped, the temperature of the film clamp is still very high. When the film clamp is clamped again, it is easy to burn the edge of the film, that is, the clamping part, which seriously affects the quality of the product. ...
