The harmful gas is then filtered and discharged through the filtering component 33, reducing the impact of the workplace on the surrounding environment.

[0021] The protection component 32 includes a hydraulic cylinder 321 fixedly installed on the top of the two lower pressure plates 2, one side of the two hydraulic cylinders 321 is fixedly connected to the fixed frame 101, a same driving plate 322 is fixedly installed between the two lower pressure plates 2, and one side of the air suction plate 31 is fixedly connected to the driving plate 322, an air pump 323 is fixedly installed on the top of the fixed frame 101, and the output end of the air pump 323 is fixedly connected to a telescopic tube 324, the other end of the telescopic tube 324 passes through the driving plate 322 and is fixedly connected to the air suction plate 31, and the telescopic tube 324 When the corrugated expansion tube 324 is bent, the lower pressure plate 2 presses down to bend the plate and simultaneously drives the driving plate 322 to move. The driving plate 322 can simultaneously drive the suction plate 31 to move, so that the suction plate 31 moves to the top of the heating roller 102. When heating and bending are performed, air can be exhausted by the vacuum pump 323, so that the suction plate 31 exhausts air from the heated part of the PVC plate, and harmful gases generated by the heating can be exhausted to prevent the harmful gases from floating around, thereby improving the safety of the working environment and protecting the health of employees.

[0022] The bottom of the lower pressure plate 2 is slidably connected to two support rods 326, one end of the two support rods 326 is fixedly connected to the same clamping plate 325, a spring 327 is sleeved on the outer side of the support rod 326, and the two ends of the spring 327 are respectively fixedly connected to the lower pressure plate 2 and the clamping plate 325.
