Problems solved by technology

Since the film will shrink when it is cold, if the surface temperature of the roller is not equal or there is a temperature difference, it will cause the film to shrink unevenly on the roller, which will eventually cause the film to be uneven and wrinkled, which will affect the production quality and production efficiency of the film.

Abstract

The invention relates to the field of cooling mechanisms, and discloses a film cooling roller. The film cooling roller comprises a roller and a cooling pipe, wherein discharge holes are formed in both ends of the roller, the roller is rotatably connected to the cooling pipe, a helical blade is arranged on the inner wall of the roller, and a helical flow channel is formed by the helical blade between the cooling pipe and the roller; a plurality of through holes are formed in the cooling pipe, a sliding rod is connected to the interior of the cooling pipe in a sliding mode, a diversion hole is formed in the sliding rod, an outlet of the diversion hole is located in the cooling pipe and faces towards one side, in which the through hole is formed, of the cooling pipe, an inlet of the diversion hole is located outside the cooling pipe, and the sliding rod is driven by a crank-connecting rod mechanism to do a reciprocal rectilinear motion in the cooling pipe, so that the diversion hole in the sliding rod is aligned with different through holes, and cooling water is led to different positions of the helical flow channel in the roller so as to uniformly cool the roller and eliminate the temperature difference of the roller. The invention aims to provide the film cooling roller so as to guarantee the cooling efficiency of the roller and eliminate the temperature difference of the surface of the roller.

Description

technical field [0001] The invention relates to the field of cooling mechanisms, in particular to a film cooling roller. Background technique [0002] In the production process of the carton, in order to improve the strength of the carton board and also to make the carton have a certain water repellency, it is usually necessary to cover the carton with a film. The film is usually made of PE film and polyethylene film, and the film is usually produced continuously at high temperature. During the forming process of the film, the heat on the film will be transferred to the support roller in contact with it, so that the temperature of the roller will also increase. It rises accordingly. And if the temperature of the roller is too high, it will cause the film to be uneven, wrinkled or stick on the roller, which will affect the production quality and production efficiency of the film. Therefore, it is usually necessary to cool the supporting roller. [0003] The Chinese patent "...
