Description

Technical Field

[0001] The utility model relates to the technical field of PVC floor processing, in particular to a rolling device for PVC floor. Background Art

[0002] PVC flooring, full name polyvinyl chloride flooring, is a flooring product made of polyvinyl chloride (PVC) resin as the main raw material. Existing PVC floors are mostly processed by rolling equipment, and rolling is divided into extrusion, calendaring, printing, coating, cooling and cutting processes;

[0003] When the existing PVC floor is subjected to the calendering process, the existing calendering equipment mostly directly calenders the extruded PVC raw materials to the required thickness. This causes some PVC raw material boards with larger thickness to be compressed too high, which may cause excessive deformation of the floor during the calendering process, causing the shape of the floor to lose the original design requirements, affecting the installation and use of the floor, and also causing the quality of the floor products to be unstable, making it difficult to ensure the consistency and standardization of each batch of products. Therefore, there are still certain shortcomings.

[0004] In summary, it is necessary to invent a rolling device for PVC floors. Utility Model Content

[0005] To this end, the utility model provides a rolling device for PVC flooring to solve the problem that the existing calendering equipment directly calenders the extruded PVC raw materials to the required thickness, which causes some PVC raw material boards with larger thickness to be compressed too high, which may cause excessive deformation of the flooring during the calendering process.

[0009] Preferably, the end of the mounting frame away from the hydraulic rod is fixed with a calendering roller a for calendering the PVC floor, and the distance between two adjacent calendering rollers a above and below is gradually reduced.

[0010] Preferably, a glue storage box is installed at the center of the top end of the outer wall of the shell, and a glue delivery pipe is installed at the upper and lower ends of the inner wall of the shell and at positions corresponding to the glue storage box. The liquid outlet end of the glue storage box is connected to the opposite end of the glue delivery pipe through a pipeline.

[0011] Preferably, the upper and lower ends of the rubber delivery pipe on opposite sides of the PVC floor are fixedly connected to hollow seats, and the opposite ends of the two hollow seats are fixedly connected to glue spray heads.

[0014] The beneficial effects of the utility model are:

[0015] In the utility model, the distance between the upper and lower calendering rollers a can be adjusted by a hydraulic rod, so that the thickness of the PVC sheet gradually reaches the required size during calendering, rather than reaching the required size at one time.
