Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, and more specifically, to a calendering apparatus for processing plastic products. Background Technology

[0002] Plastic calendering equipment is mainly used in the production of various plastic films and PVC calendered artificial leather products. It usually has multiple rollers to press the plastic material evenly.

[0003] A search revealed that utility model patent CN221937345U discloses a calendering device for plastic products, including a housing. A protective door is located on the right side of the housing, with a feed inlet in the middle of the right side of the door. A transparent observation port is located above the feed inlet. A motor is fixedly connected to the upper right end of the front of the housing. The output end of the motor passes through the housing and is connected to a rotating shaft. Two rotating shafts are symmetrically arranged around the right side of the housing. A fixing block is fixedly connected to the right end of the top of the housing. A fixing groove is located at the bottom of the fixing block, and a spring is fixedly connected within the groove. A scraper is fixedly connected to the other end of the spring. This patent, by setting up motors one and three, rotating shafts one and three, pressure rollers one and three, can achieve the calendering of plastic products. The setting up scrapers one, springs one, two, two, three, and three springs can achieve the cleaning of residues on the surfaces of pressure rollers one and two.

[0004] The aforementioned patent also has the following shortcomings: although the residue adhering to the pressure roller can be cleaned off by a scraper, it is not convenient to collect and use the cleaned plastic material, resulting in poor practicality. Therefore, we propose a calendering device for processing plastic products. Utility Model Content
