Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a roller cleaning device. Background Art

[0002] When the PVC laminating machine produces base fabric sizing products, the lamination of the base fabric and the bottom film first requires heating the base fabric and the bottom film in the base film large cylinder to increase the plasticization of the base fabric, and then laminating through the second pressing to achieve the effect of complete lamination with the bottom film. The surface of the PVC laminating machine roller is prone to dirt, residues or other contaminants, and the attached dirt, residues or other contaminants are likely to affect the subsequent use of the PVC laminating machine roller. Therefore, the PVC laminating machine roller needs to be cleaned by a roller cleaning device.
