Two screws 7 are rotatably connected to the sliding frame 6, and the two screws 7 are connected to the mounting shell 1 through threads. Two driven rollers 8 are rotatably connected to the sliding frame 6, and the driven rollers 8 are used to squeeze the PVC board for correction. A pressing mechanism is provided on the sliding frame 6, and the pressing mechanism is connected to the driven roller 8. The sliding frame 6 is also provided with a clamping mechanism, which contacts the rotating roller 2. The pressing mechanism is used to intermittently correct the PVC board by pressing, and the clamping mechanism is used to limit the PVC board.

[0021] The transmission assembly 4 includes transmission wheels, wherein the two transmission wheels of one group of transmission assemblies 4 are fixedly connected to the two rotating rollers 2 located in the middle and on one side, respectively, and the two transmission wheels of another group of transmission assemblies 4 are fixedly connected to the two transmission rollers located in the middle and on the other side, respectively. The two transmission wheels on the transmission roller located in the middle are arranged at intervals, and a belt is wound between the two rotating wheels on the two groups of transmission assemblies 4, and the two belts are arranged at intervals.

[0022] The heating plate 5 is provided with a limiting protrusion, and the limiting protrusion of the heating plate is used to prevent the PVC plate from deflecting.

[0023] The pressing mechanism includes a pressing plate 9, which is used to press the PVC board. The four pressing plates 9 are respectively connected to the two sides of the sliding frame 6 in a sliding manner. A first compression spring 10 is connected between the four pressing plates 9 and the sliding frame 6. The two pressing plates 9 on the same side form a group. A connecting frame 11 is fixedly connected between the two sides of the two pressing plates 9 in the same group. Cams 12 are fixedly connected to both ends of the two driven rollers 8. The cams 12 are used to squeeze the connecting frame 11. The four cams 12 are respectively in contact with the four connecting frames 11.

[0024] The clamping mechanism includes a fixed frame 13, two of the fixed frames 13 are fixedly connected to both sides of the sliding frame 6, a sliding rod 14 is slidably connected between the two fixed frames 13, two second compression springs 16 are connected between the sliding rod 14 and the two fixed frames 13, and the two second compression springs 16 are symmetrically arranged. An auxiliary roller 15 is rotatably connected to the sliding rod 14, and the auxiliary roller 15 is in contact with one of the three rotating rollers 2.

[0025] At first, the cam 12 presses against the connecting frame 11, and the first compression spring 10 is compressed. When the warped PVC board needs to be corrected, the staff first adjusts the distance between the sliding frame 6 and the mounting shell 1 by rotating the screw 7 according to the thickness of the PVC board. The staff starts the servo motor 3 and the heating plate 5. The output shaft of the servo motor 3 rotates through the transmission component 4 to drive the rotating roller 2 to rotate together. The rotation of the rotating roller 2 drives the auxiliary roller 15 to rotate, and the PVC board is placed between the rotating roller 2 and the auxiliary roller 15. The PVC board squeezes the auxiliary roller 15, and the auxiliary roller 15 drives the sliding rod 14 to move upward. The second compression spring 16 is compressed, thereby preventing the PVC board from being damaged, and then the deformed PVC board is pressed and accurately fed in for correction. The rotation of the rotating roller 2 and the auxiliary roller 15 will drive the PVC board to move. The rotating roller 2 continues to rotate to drive the PVC board to move. While the PVC board moves, the heating plate 5 will heat the PVC board to soften the PVC board. The movement of the PVC board causes the driven roller 8 to rotate to squeeze the PVC board. The PVC sheet is pressed, and then the output shaft of the servo motor 3 is reversed to drive the rotating roller 2 to reverse and squeeze again through the driven roller 8. This is repeated. While the rotating roller 2 rotates to drive the PVC sheet to move, the driven roller 8 will repeatedly squeeze the PVC sheet, and then correct the PVC sheet, thereby enhancing the correction effect of the PVC sheet. While the driven roller 8 rotates, it drives the cam 12 to rotate, and the cam 12 is out of contact with the connecting frame 11. The spring reset drives the pressure plate 9 to move downward, and the pressure plate 9 moves downward to squeeze the PVC sheet under the pressure plate 9. The driven roller 8 rotates in the opposite direction to drive the protrusion to squeeze the connecting frame 11 to lift the pressure plate 9. The first compression spring 10 is compressed, and this is repeated. The rotation of the driven roller 8 will drive the protrusion to repeatedly disengage from the connecting frame 11, so that the pressure plate 9 moves and repeatedly squeezes the PVC sheet, thereby repeatedly flattening the PVC sheet, and then assisting in the correction of the PVC sheet, thereby further enhancing the correction effect. After the correction is completed, the corrected PVC sheet is sent out by the rotating roller 2, and the PVC sheet can be cooled and shaped.
