[0002] Polyvinyl chloride (PVC) foam board is a kind of board with a porous structure produced by using PVC as the main raw material, adding foaming agents and other additives, and adopting a specific process. The production of PVC foam board is a technological process involving complex chemical reactions and physical changes. From the selection of raw materials to the precise control of the production process, and then to the design of a reasonable formula, each link affects the performance of the final product. In the future, with the continuous development and application of new materials and new technologies, the production of PVC foam board will be more environmentally friendly and efficient, meeting the wider application needs in various fields.
[0003] Currently, during the production of PVC foam board, a cutting process is required. Since the foam board material is relatively soft, after the cutting blade divides the foam board into multiple segments, the distance between the clamps is fixed, so there will be a certain gap between each segment of the foam board, which easily leads to errors in subsequent cutting work, thereby reducing the cutting accuracy. Summary of the Utility Model

[0018] Among them, threads are processed on the electric rotating rods 4, thread grooves are provided at both ends of the lifting plate 5, and both sides of the lifting plate 5 are in contact with the inner walls of the first chutes 3; it is convenient to control the distance between the cutting blade 13 and the bearing plate 9.
[0019] Among them, a guide rod 16 is horizontally connected inside the groove 15, the elastic member 17 is sleeved on the guide rod 16, and the first clamping plate 10 is slidably connected to the guide rod 16; enabling the first clamping plate 10 to move according to the position of the foam board.
