[0013] By adopting the above technical solution, the limiting slider slides in the limiting slide groove, so that the lifting and lowering trajectory of the movable block can be limited, thereby ensuring high lifting and lowering stability of the movable block.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] The PVC foam board coating exhaust device of the technical solution of the present application rolls the negative pressure on the surface of the foam board through a pressure roller, and the coating on the surface of the foam board can be punctured by a puncture cone during the rolling process, and the gas can be completely discharged by rolling at the same time, thereby avoiding residual gas and ensuring the coating effect;

[0018] After the puncturing cone punctures the film on the foam board, the spring can be compressed when pressure is applied to the foam board, so that the puncturing cone is stored in the groove, thereby avoiding damage to the foam board and achieving a protective effect.

[0027] See also Figure 1-3 The utility model provides a technical solution: a PVC foam board film exhaust device, comprising a base 1, support plates 2 are fixed on both sides of the top of the base 1, the outer wall of the support plate 2 is provided with a strip hole 21, a movable block 22 is installed in the inner cavity of the strip hole 21, a pressure roller 3 is rotatably installed between the two movable blocks 22, a servo motor 24 is fixed on the outer wall of one of the movable blocks 22, the transmission shaft of the servo motor 24 passes through the movable block 22 and is fixedly connected to one end of the pressure roller 3, and a plurality of uniformly distributed puncture cones 31 are installed on four sides of the outer wall of the pressure roller 3;

[0028] In actual use, the foaming board is placed on the base 1 and moved by the traction mechanism. During the movement, the pressing roller 3 is driven to rotate by the servo motor 24, so as to achieve rolling of the surface of the foaming board. During the rolling process, the piercing cone 31 pierces the film on the surface of the foaming board, so that the gas can be squeezed out in cooperation with the rolling to ensure the film coating effect.

[0029] Furthermore, mounting holes 11 are provided at the four corners of the surface of the base 1. The arrangement of the mounting holes 11 facilitates the installation and fixation of the entire device.

[0030] Furthermore, an electric push rod 23 is fixed to the top of the inner cavity of the strip hole 21, and the tail end of the electric push rod 23 is fixedly connected to the top of the movable block 22. When the servo motor 24 drives the pressing roller 3 to press the foaming board, starting the electric push rod 23 can drive the movable block 22 to descend, so that the pressing roller 3 fits the surface of the foaming board, ensuring the pressure effect, and can adapt to foaming boards of different thicknesses;

[0031] It is worth mentioning that both side walls of the inner cavity of the strip hole 21 are provided with limit slots 25, and the inner cavity of the limit slots 25 is plugged with an adapted limit slider 26, and the outer wall of the limit slider 26 is fixedly connected to the corresponding side wall of the movable block 22, and the limit slider 26 slides in the limit slot 25, so as to limit the lifting trajectory of the movable block 22, thereby ensuring the high lifting stability of the movable block 22;

[0032] like Figure 1 and 2 As shown; the outer wall of the pressure roller 3 is provided with a groove 32 corresponding to the puncturing cone 31, and a spring 33 is fixed to the inner end surface of the inner cavity of the groove 32, and the outer end of the spring 33 is fixedly connected to the inner end of the puncturing cone 31;

[0033] After the puncturing cone 31 punctures the film on the foam board, the spring 33 can be compressed when the foam board is pressed, so that the puncturing cone 31 is stored in the groove 32, thereby avoiding damage to the foam board and achieving a protective effect.

[0034] The implementation principle of the PVC foam board coating exhaust device of the present application is as follows: in actual use, the foam board is placed on the base 1, and the electric push rod 23 is started to drive the movable block 22 to descend, so that the pressure roller 3 is attached to the surface of the foam board to ensure the pressure effect, and the traction mechanism is used to move the pressure roller 3. During the movement, the servo motor 24 drives the pressure roller 3 to rotate, so as to achieve rolling of the surface of the foam board. During the rolling process, the piercing cone 31 will pierce the coating on the surface of the foam board, so that the gas can be squeezed out in cooperation with the rolling to ensure the coating effect, and after the piercing cone 31 pierces the coating on the foam board, the spring 33 can be compressed when the foam board is pressurized, so that the piercing cone 31 is stored in the groove 32, thereby avoiding damage to the foam board, thereby achieving a protective effect.
