This bearing has a simple structure and has load-bearing capacity. The deep groove ball bearing has the characteristics of high force, low friction and high speed. There is a deep groove structure between the inner and outer rings of the deep groove ball bearing, hence the name. This structure enables the bearing to withstand radial and axial loads and is suitable for high-speed operation. The balls roll inside the bearing, reducing friction, thereby reducing energy loss and heat generation. Deep groove ball bearings are commonly used in various mechanical equipment and tools, such as motors, automobile transmission systems, industrial equipment, etc. Selecting a suitable deep groove ball bearing requires consideration of factors such as load, speed, working environment and bearing size. A rotating shaft 5 runs through the interior of the deep groove ball bearing 10, and a fixed pressure roller 11 is also provided on the shaft of the rotating shaft 5; a cylinder base 12 is provided at the upper end of the support frame 8, and a telescopic cylinder 13 is provided on the cylinder base 12.

The slide rail 17 is a device for providing smooth sliding support, usually made of metal or plastic. The slide rail 17 is provided on the base plate 1 so that the slider 18 can slide along a certain track thereon. The slider 18 with a plunger is a specially designed slider, which usually consists of a plunger and a sliding part. The plunger is connected to the slide rail 17. Through the connection between the plunger and the slider, the slider can slide along the track on the slide rail. This design can provide more stable sliding performance and reduce friction and vibration during sliding. The slide rail and the slider with a plunger have a wide range of applications. They can be used to achieve smooth movement, positioning and adjustment of objects.

Since the multi-stage gear 6 is provided with transmission teeth with increasing diameters in sequence, the handwheel is rotated to drive the plunger slider 18 to move through the threaded connection, and indirectly drive the multi-stage gear 6 to move, so that the gear of the corresponding diameter on the multi-stage gear 6 is meshed with the driven gear 16, driving the multi-stage gear 6 to rotate, so that the fixed pressure roller 11 and the movable pressure roller 15 can achieve the calendering effect.

[0021] Specifically, a coupling is provided between the driving end of the drive motor 4 and the rotating shaft. The coupling is a device used to connect two shafts and transmit rotational force. It can solve problems such as misalignment between shafts, a certain distance between shafts, or the need for flexible connection between shafts. The coupling is usually composed of two interconnected parts, which are respectively connected to the two shafts. This connection method allows the two shafts to keep synchronized when rotating at high speed, and can absorb some deviations and vibrations between the shafts. There are many types of couplings. Common types include elastic couplings, gear couplings, worm couplings, etc. Different types of couplings are suitable for different working conditions and requirements. Selection of a suitable coupling requires consideration of factors such as shaft diameter, rotation speed, torque transmission requirements, and working environment.

[0022] Specifically, the number of the support frames 8 is two, and they are respectively arranged on the left and right sides of the profile base 3 .

[0023] Specifically, sliding bearing seats are provided on both the left and right sides of the movable pressing roller 15 , and the sliding bearing seats are slidably arranged on the inner side of the supporting frame 8 .

[0024] Working principle: When the utility model is working, the telescopic cylinder 13 is set to drive the lifting base 14 to move, and the lifting base 14 drives the mobile pressure roller 15 to move. In conjunction with the fixed pressure roller 11, the distance between the fixed pressure roller 11 and the mobile pressure roller 15 can be adjusted according to the actual required rubber thickness. The driving motor 4 is set to drive the rotating shaft 5 to rotate, and the rotating shaft 5 drives the multi-stage gear 6 and the fixed pressure roller 11 to rotate.
