Description

Technical Field

[0001] The utility model relates to the technical field of PVC plate traction, and more specifically, to a plate traction device for PVC plate production. Background Art

[0002] The natural color of polyvinyl chloride is slightly yellow and translucent, with gloss. Its transparency is better than polyethylene and polypropylene, but worse than polystyrene. Depending on the amount of additives used, it is divided into soft and hard polyvinyl chloride. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene, but lower than that of polypropylene. Whitening will occur at the inflection point. Common products include: plates, pipes, soles, toys, doors and windows, wire sheaths, stationery, etc. It is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene.

[0003] For example, the patent document with the announcement number CN 219407943 U discloses a sheet traction device for PVC sheet production, including a traction platform, an upper conveying structure, a lower conveying structure, a lifting guide structure and a power structure, wherein the upper conveying structure is arranged directly above the lower conveying structure; the upper conveying structure includes an upper conveying bracket, on which an upper active roller and an upper driven roller are rotatably mounted, and an upper conveyor belt is mounted on the outer side of the upper active roller and the upper driven roller; the lower conveying structure includes a lower conveying bracket, on which a lower active roller and a lower driven roller are rotatably mounted, and a lower conveyor belt is mounted on the outer side of the lower active roller and the upper and lower driven rollers; two mounting seats are fixedly mounted on the traction platform, the lower conveying bracket is fixedly connected to the mounting seats, the lower conveyor belt is spaced apart from the traction platform, the lifting guide structure is connected to the upper conveying bracket, and the power structure is connected to the upper active roller and the lower active roller. The utility model has the advantages of being able to transmit with a single power, making the two conveyor belts synchronized, and better ensuring the quality of the sheet.
