Description

Technical Field

[0001] The utility model relates to the technical field of traction rollers, in particular to an adjustable traction roller for PVC processing. Background Art

[0002] PVC refers to polyvinyl chloride, which is the third largest synthetic polymer plastic in the world. It is a polymer formed by the polymerization of vinyl chloride monomer in the presence of initiators such as peroxides and azo compounds or under the action of light or heat according to the free radical polymerization mechanism. In the production process of PVC, traction rollers are needed to pull the sheet raw materials.

[0003] A PVC wire traction cutting machine is disclosed in the Chinese utility model patent application No.: CN202223613173.X. By providing a cleaning frame, it is convenient to use. The two ends of the cleaning frame can be threadedly connected to the threaded rod. The threaded rod is driven to rotate by a rotating machine. Therefore, during the cutting process, the threaded rod is driven to rotate by the rotating machine, thereby driving the cleaning frame to move so that the cleaning brush sweeps the cut waste to the position of the collection tank and falls into the inner side of the cutting table for storage, which can effectively ensure that the accumulation of waste is reduced.

[0004] Although the above patent realizes the function of traction in the PVC processing process, the above patent has the following disadvantages when used: the spacing between the traction rollers in the prior art is usually fixed, but due to different production batches of different products, different raw materials and many other reasons, the spacing requirements between the traction rollers are also different, which cannot be applied to different production requirements, has poor applicability and is inconvenient to use. Therefore, we propose an adjustable traction roller for PVC processing. Utility Model Content
