Abstract

The invention provides a cooling device of a plastic thin film processing device and belongs to the technical field of machinery. The cooling device solves the problem of complex operation of a cooling roller in a thin film processing line. The cooling device includes two pedestals and a roller arranged therebetween. One end of the roller is sealed while the other one end is opened. A rotational portion is arranged on the sealed end and is axially fixed to the corresponding pedestal. A liquid inlet pipe is installed in the opened end and comprises a liquid inlet portion, which is axially arranged along the roller, and a liquid outlet portion, which is arranged in the radial direction of the roller. The outer end of the liquid inlet portion is stretched out from the opened end and is fixed to the corresponding pedestal. A ring-shaped connection portion is arranged on the edge of the inner end of the liquid inlet portion. A sealing ring is arranged between the connection portion and the roller. A refrigerating chamber is formed between the connection portion and the inner wall of the roller. The liquid inlet portion is communicated with a refrigerating system. The refrigerating system works so that a refrigerant cyclically flows in the refrigerating chamber. The cooling device is convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a cooling device, in particular to a cooling device in plastic film processing equipment. Background technique [0002] During the processing of the plastic film, the material is first melted, then shaped, cooled, and finally the film is rolled up by the receiving mechanism. At present, the cooling process of the film mainly adopts a long transfer table between the film forming machine and the winding mechanism, and cools it through the air in the room, so that not only the cooling speed is slow, but also the long transfer table occupies It is large and has certain requirements for the factory building. [0003] For the above problems, people have realized the shortcomings and made improvements, such as a cooling roller of a film processing line disclosed in the Chinese patent library [ Application Number: 201320062219.5 ;Announcement number: CN 203125808 U , incl...
