Description

Technical Field

[0001] The present invention relates to the technical field of PVC sheet production equipment, and in particular to a device for cutting off the edge of a PVC sheet coating. Background Art

[0002] PVC board is a board with a honeycomb mesh structure made of PVC as raw material. After the PVC board is produced, a protective film is usually hot-pressed on its surface to prevent scratches during transportation. Usually, when the PVC board is hot-pressed online, the rolled film deviates slightly when it is unrolled due to factors such as uneven tensile force. Although it will be adjusted on the production line, the adjustment is delayed, so the width of the film is generally larger than the width of the PVC board. As a result, there is excess film on the edges of both sides of the PVC board after lamination. However, the film is very soft and thin and is not easy to remove. Therefore, in the prior art, the film is removed by cutting off about 5 to 10 mm from the edges of both sides of the hard PVC board. This operation method results in waste of raw materials and waste pollution. Summary of the invention
