Description

Technical Field

[0001] The utility model relates to the technical field of calendering equipment, in particular to a PVC artificial leather calendering equipment. Background Art

[0002] PVC artificial leather is a common man-made material, mainly made of polyvinyl chloride. It is widely used in clothing, furniture, automotive interiors, footwear and many other applications. Calendering is an important process in the production of PVC artificial leather. It is formed into a film or sheet by mixing PVC resin with plasticizers, stabilizers and other raw materials, and then pressing and heating it through a calender. PVC artificial leather is favored for its excellent performance and wide application. Through the calendering process, artificial leather products suitable for different needs can be produced.

[0003] For example, the TPU artificial leather calendering device disclosed in the authorization announcement number CN221437000U can effectively calender artificial leathers of different thicknesses and effectively shear the edges of artificial leather smoothly by adjusting the height of the adjusting roller by rotating the gear through the provided limiting device and the adjusting device. However, the position of the cutting knife will remain stationary during cutting, which will easily cause wrinkles in the calendering process of the artificial leather, and the trimming position cannot be adjusted during use, thereby reducing the use effect of the device. Therefore, the above problems need to be solved. Utility Model Content
