Description

Technical Field

[0001] The utility model relates to the technical field of calenders, in particular to a compacting device for a film calender. Background Art

[0002] The calender is composed of two or more rollers, which are arranged according to the heating method. It can be divided into cold pressing and hot pressing. Cold pressing is suitable for materials that do not require heating, such as graphite film, graphite sheet, absorbing material, shielding material, magnetic material, non-ferrous metal material, etc.

[0003] When the calender is working, the more uniform the thickness of the calendered film is, the more beneficial it is to the performance improvement and stability of the film. The existing calender relies on the weight of the upper roller itself to apply pressure, and lacks constant pressure protection measures, resulting in the calendered film being thick or thin, affecting the quality of the output film.

[0004] Therefore, it is particularly important to design a film calender pressing device to solve the above-mentioned defects. Utility Model Content

[0018] First, the hydraulic rod drives the sliding frame and the upper pressure roller to descend as a whole according to the calendering requirements. When the upper pressure roller contacts the film, the compression spring group drives the upper pressure roller to calender the film, providing constant pressure protection for the film being calendered, so that the upper pressure roller applies force to make the calendering uniform, thereby improving the processing quality of the film;

[0019] Secondly, the lower pressing roller provides hot pressing processing for the material that needs hot pressing through the heating ring to improve the overall applicability of the device. The calendered film enters the cooling chamber. While the conveying roller conveys the film, the cooling fan physically cools the film to avoid deformation of the film due to large temperature difference during cooling, which affects the subsequent processing. The heat dissipation window assists in heat dissipation inside the cooling chamber.

[0020] Finally, the sliding frame is slidably connected to the limiting slide groove through a directional pulley, thereby improving the smoothness and stability of the height adjustment of the upper pressure roller. BRIEF DESCRIPTION OF THE DRAWINGS
