Description

Technical Field

[0001] The present application relates to the technical field of PVC film production equipment, and in particular to a PVC film water bath heating device. Background Art

[0002] The main component of PVC is polyvinyl chloride, which is slightly yellow, translucent and shiny. After the production of PVC film is completed, it is usually necessary to test the shrinkage of the PVC film. The shrinkage test is generally to heat the PVC film and then measure the heated PVC film. The shrinkage of the PVC film is determined according to the change in the size of the PVC film after heating. The existing PVC film is usually heated in a water bath, which is controlled by a heating tube and a sensor to uniformly heat the PVC film.

[0003] The water bath mainly includes a pot body, water is injected into the pot body, and an electric heating component for heating the water is set at the bottom of the pot body. When the PVC film is heated by the water bath, the PVC film is directly placed in the water bath, and then taken out for measurement after heating. There are several problems:

[0004] 1. The PVC film will stack together in the water bath and cannot be heated evenly, resulting in inaccurate test results;

[0005] 2. The PVC film is directly put into the water bath, which makes it difficult to take out. It needs to be taken out with tools, which is cumbersome. Utility Model Content
