[0002] A pressure roller is a device that can evenly press a plasticized or calendered film onto a substrate. It is usually used in combination with a cooling roller and a calender roller. Especially in the processes of extrusion coating and calender coating, the pressure roller can be a rubber roller, and sometimes it also refers to the rubber roller on an embossing machine, which can cooperate with an engraved roller to evenly emboss on a sheet.

[0003] When in use, the pressure roller needs to be installed on the frame of the device first. In the prior art, most pressure rollers are fixedly connected during installation. When the pressure roller needs to be maintained, cleaned, etc., that is, when periodic maintenance and upkeep are required, the fixedly connected pressure roller is not convenient for convenient connection and disassembly, which increases the operation difficulty and time cost, and the practicability is insufficient. Therefore, it is necessary to redesign a pressure roller convenient for connection in view of the above problems. Content of the Utility Model

Detailed implementation manners

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Refer to Figures 1-5 , a pressure roller convenient for connection, including a pressure roller body 1 and a support frame 2. A double-headed screw 3 is rotatably installed inside the support frame 2. A motor 4 connected to the double-headed screw 3 is fixedly installed on the outer wall of the support frame 2. Two moving sleeves 6 are threadedly installed on the outer wall of the double-headed screw 3 through a limiting mechanism. The limiting mechanism includes a limiting rod 5 fixedly installed inside the support frame 2. The limiting rod 5 slidably penetrates through the two moving sleeves 6. The limiting rod 5 can limit the two moving sleeves 6, so that the two moving sleeves 6 can only axially move along the outer wall of the double-headed screw 3. The bottom walls of the two moving sleeves 6 are both fixedly installed with a first connection frame 7. A second connection frame 9 is rotatably connected inside the two first connection frames 7 through a connection mechanism. The connection mechanism includes a connection plate 8 rotatably installed inside the first connection frame 7. The end of the connection plate 8 is rotatably connected to the inside of the second connection frame 9. The bottom walls of the two second connection frames 9 are commonly fixedly connected with a connection plate 10.

[0023] Two stabilizing rods 11 are slidably penetrated and installed on the upper end surface of the support frame 2. The ends of the two stabilizing rods 11 are both fixedly connected to the upper end surface of the connection plate 10. Limiting plates 12 are fixedly installed on the outer walls of the two stabilizing rods 11. The limiting plates 12 can prevent the support frame 2 from detaching from the outer walls of the stabilizing rods 11. Two connection frames 13 are fixedly installed on the bottom wall of the connection plate 10. Rhombic rods 14 are fixedly installed inside the two connection frames 13. Moving plates 15 are slidably installed on the outer walls of the two rhombic rods 14. The outer walls of the two moving plates 15 are both connected to the inner wall of the same-side connection frame 13 through an elastic mechanism. The elastic mechanism includes a spring 16 installed on the outer wall of the rhombic rod 14. The two ends of the spring 16 are elastically connected to the inner wall of the connection frame 13 and the outer wall of the moving plate 15 respectively. The outer walls of the two moving plates 15 are both rotatably installed with bushings 18 through a connection mechanism. The connection mechanism includes a connection shaft 17 fixedly installed on the outer wall of the moving plate 15. The end of the connection shaft 17 is rotatably connected to the outer wall of the bushing 18. The rotating shafts at both ends of the pressure roller body 1 are slidably installed inside the two bushings 18.

[0024] When the utility model is in use, the moving plate 15 can be toggled to slide on the outer wall of the rhombic rod 14 and pull the spring 16, so that the distance between the two shaft sleeves 18 can be adjusted. Then, the two ends of the rotating shaft of the roller body 1 can be aligned with the ends of the same-side shaft sleeve 18 respectively. Subsequently, the toggling of the moving plate 15 can be released. At this time, under the elastic action of the spring 16, the moving plate 15 can slide and reset on the outer wall of the rhombic rod 14, and drive the two shaft sleeves 18 to be sleeved on the outer walls of the two ends of the rotating shaft of the roller body 1 respectively. Thus, the convenient connection of the roller body 1 can be realized. And under the elastic action of the spring 16, the shaft sleeve 18 can always be sleeved on the outer wall of the rotating shaft of the roller body 1, so as to avoid the separation of the rotating shaft of the roller body 1 from the two shaft sleeves 18;

[0025] When the roller body 1 is stressed during use, with the cooperation of the two connecting shafts 17, the two shaft sleeves 18 can drive the roller body 1 to rotate. And during use, the motor 4 can drive the double-headed screw rod 3 to rotate. The double-headed screw rod 3 can drive the two moving sleeves 6 to move through the cooperation with the limiting rod 5. At this time, the two moving sleeves 6 drive the two first connection frames 7 to approach each other, and drive the second connection frame 9 to move through the cooperation of the connection plate 8. Thus, the second connection frame 9 can drive the roller body 1 to move downward through the cooperation of the connection plate 10. Driven by the double-headed screw rod 3, the height of the roller body 1 can be conveniently adjusted, increasing its convenience during use. And when adjusting the height of the roller body 1, the connection plate 10 can drive multiple stabilizing rods 11 to slide on the bottom wall of the support frame 2. Thus, the stability of the roller body 1 during use is increased through the cooperation of the multiple stabilizing rods 11.

[0026] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the utility model.
