The vacuum roller in a cast film machine is a crucial step in traction of PET film, and is particularly crucial for controlling the thickness precision of cast ceramic film. However, existing equipment faces a challenge in integrating the vacuum roller with the automatic web-correcting assembly. Because the automatic web-correcting assembly moves the vacuum roller, the transmission mechanism connected to the vacuum roller, such as the motor, remains stationary. This prevents the vacuum roller and motor from working together when the web-correcting mechanism is operating. Utility Model Content

[0014] The following is combined with Figure 1 、 2 The specific implementation methods of the present utility model are further described.

[0015] The vacuum roller of the casting machine and the automatic deviation correction coupling mechanism include a vacuum roller 3 installed on the automatic deviation correction component 1 through a roller support frame 2, one end of the vacuum roller 3 is connected to the vacuum joint 4, and the connection of the vacuum pipe can enable the vacuum roller 3 to work in adsorption and traction, and the other end is connected to the two-way universal joint 5 and the spline shaft 10 in sequence. The spline shaft 10 is sheathed with a spline nut 9, so that the spline shaft 10 can move freely in the spline nut 9, so that the vacuum roller 3 can deflect at any angle when the automatic deviation correction component 1 is working, eliminating the influence of the position change of the vacuum roller 3 caused by the operation of the automatic deviation correction component 1, and can increase the accuracy of the PET film operation. The spline nut 9 is embedded in two ball bearings 8 and a synchronous pulley 7. The two ball bearings 8 are located on both sides of a synchronous pulley 7. The outer sides of the two ball bearings 8 are installed with bearing mounting seats 6, and are limited by the bearing mounting seats 6. The synchronous pulley 7 is connected to the transmission mechanism through a synchronous belt, which ensures the free rotation of the vacuum roller 3 and solves the coupling problem between the vacuum roller 3 and the automatic deviation correction component 1.

[0016] The working process is: the vacuum roller 3 is installed on the automatic deviation correction component 1 through the roller support frame 2, and one end of the vacuum roller 3 is connected to the vacuum joint 4. Connecting the vacuum pipe can enable the vacuum roller 3 to work by adsorption and traction. When the automatic deviation correction component 1 performs deviation correction adjustment, the axial end angle and position of the vacuum roller 3 will change. The two-way universal joint 5 connected to the axial end of the vacuum roller 3 will continuously correct the changes caused by the angle. The spline shaft 10 connected to the other end of the two-way universal joint 5 and the spline nut 9 can move freely, eliminating the position change of the axial end of the vacuum roller 3; the spline nut 9 is embedded in two ball bearings 8 and limited by the bearing mounting seat 6. A synchronous pulley 7 is installed on the spline nut 9, which can be connected to a transmission mechanism such as a motor in a fixed position, ensuring the precise and free rotation of the vacuum roller 3.

[0017] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
