Description

Technical Field

[0001] This utility model relates to the field of calendering technology, and more specifically, to a device for pre-treatment of the bottom film of a calendering line and integrated molding of silicone. Background Technology

[0002] Calenders consist of two or more rollers arranged according to the heating method. They can be divided into cold pressing and hot pressing. Cold pressing is suitable for materials that do not require heating, such as graphite films, graphite sheets, microwave absorbing materials, shielding materials, magnetic materials, and non-ferrous metal materials. Hot pressing is further divided into water heating, electric heating, oil heating, and electromagnetic heating. All of these are machines that press and stretch materials such as rubber, silicone rubber, silicone rubber, phase change materials, PTFE, or plastics into sheets of a certain thickness and surface shape at a certain temperature. They can also be used to coat fiber optic fabrics or steel wire fabrics with adhesive.

[0003] The authorization announcement number "CN213972190U" describes "a fully automatic calender for producing thermally conductive silicone pads, including a base plate. A first vertical plate and a second vertical plate are fixedly installed on the upper left and upper right sides of the base plate, respectively. An mounting plate is fixedly installed on the upper left side of the first vertical plate. A first motor is fixedly installed in the middle of the upper part of the mounting plate. A first rotating shaft is fixedly installed at the output end of the first motor. A first pressure roller is fixedly sleeved on the middle of the outer surface of the first rotating shaft. Both the first and second vertical plates have through holes in their middle sections, and a calendering device passes through the through holes. This fully automatic calender for producing thermally conductive silicone pads, through the driving of a lifting component and the arrangement of the through holes, allows for adjustment of the distance between the first and second pressure rollers, meeting the production needs of thermally conductive silicone pads of various thicknesses and suitable for widespread use. The cleaning component ensures the calendering effect while facilitating the next use of the calender."

[0004] The aforementioned patent facilitates the adjustment of the distance between the two pressure rollers and surface cleaning. However, in actual use, the width of the pressure rollers cannot be adjusted, making it inconvenient to restrict the calendering process of silicone. The extended part of the silicone is prone to touching the outer wall of the two vertical plates, resulting in the loss and waste of raw materials. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a pretreatment device for the bottom film of the calender head and an integrated silicone molding device, which aims to solve the problems mentioned in the background art.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0008] The frame body has fixed pressure rollers rotatably embedded between its two outer walls, and each outer wall has a limit groove, with a movable pressure roller movably embedded between the two limit grooves; and

[0009] The limiting mechanism includes a bidirectional screw and a limiting rod. The bidirectional screw is rotatably installed between the outer walls of both sides of the frame. Two threaded blocks are threadedly sleeved on the outer surface of the bidirectional screw. The limiting rod is fixedly installed between the outer walls of both sides of the frame. Two limiting blocks are movably sleeved on the outer surface of the limiting rod. A limiting frame is fixedly installed between each threaded block and the outer wall of the corresponding limiting block.

[0010] As a preferred embodiment of this utility model, each of the limiting frames is arc-shaped, and its inner diameter is adapted to the outer diameter of the fixed pressure roller and the movable pressure roller.

[0011] As a preferred embodiment of this utility model, a limiting motor is fixedly installed on one side of the outer wall of the frame, and the output end of the limiting motor is fixedly connected to one end of the bidirectional screw.

In this solution, the limiting frame is arc-shaped, and the inner wall of the limiting frame is adapted to the outer wall of the fixed pressure roller and the movable pressure roller, which facilitates simple cleaning of the outer wall of the fixed pressure roller and the movable pressure roller.

[0027] Frame 1, with fixed pressure rollers 2 rotatably embedded between the outer walls of both sides of frame 1, and limit grooves formed on both outer walls of frame 1, with movable pressure rollers 3 movably embedded between the two limit grooves; and

[0028] The limiting mechanism 4 includes a bidirectional screw 401 and a limiting rod 402. The bidirectional screw 401 is rotatably installed between the outer walls of both sides of the frame 1. Two threaded blocks 403 are threadedly sleeved on the outer surface of the bidirectional screw 401. The limiting rod 402 is fixedly installed between the outer walls of both sides of the frame 1. Two limiting blocks 404 are movably sleeved on the outer surface of the limiting rod 402. A limiting frame 405 is fixedly installed between the outer wall of each threaded block 403 and the corresponding limiting block 404.

[0029] In this embodiment, the movable pressure roller 3 moves up and down within the limiting groove on the frame 1, facilitating the adjustment of the distance between it and the fixed pressure roller 2, and the adjustment of the silicone calendering thickness. The two limiting frames 405 in the limiting mechanism 4 facilitate the limitation of the silicone calendering width, avoiding waste of silicone raw materials during processing. At the same time, the bidirectional screw 401 rotates, facilitating the movement of the two threaded blocks 403 towards or away from each other, thereby facilitating the adjustment of the distance between the two limiting frames 405 and improving the effectiveness of the limiting mechanism 4. The cooperation of the limiting rod 402 and the limiting block 404 improves the movement stability of the limiting frame 405.

[0030] Please refer to the specific details. Figure 1-3 As shown, each limiting frame 405 is arc-shaped, and its inner diameter is compatible with the outer diameter of the fixed pressure roller 2 and the movable pressure roller 3.

[0031] In this embodiment, the limiting frame 405 is arc-shaped, and the inner wall of the limiting frame 405 is adapted to the outer wall of the fixed pressure roller 2 and the movable pressure roller 3, which facilitates simple cleaning of the outer wall of the fixed pressure roller 2 and the movable pressure roller 3.

[0032] Please refer to the specific details. Figure 2 As shown, a limiting motor 406 is fixedly installed on one side of the outer wall of the frame 1, and the output end of the limiting motor 406 is fixedly connected to one end of the bidirectional screw 401.

[0033] In this embodiment, the motor 406 is restricted to facilitate the rotation of the bidirectional screw 401, thereby improving the ease of use of the restriction mechanism 4.

[0034] Please refer to the specific details. Figure 2 As shown, limit frames 5 are fixedly installed on both outer walls of the frame 1. Support plates 6 are movably sleeved between the outer surfaces of each limit frame 5, and the shafts of the movable pressure rollers 3 movably pass through the two support plates 6.

[0035] In this embodiment, the limiting frame 5 facilitates the lifting and lowering of the support plate 6, and the support plate 6 facilitates the position adjustment of the movable pressure roller 3, while improving the stability of the movable pressure roller 3 in use.

[0036] Please refer to the specific details. Figure 1 As shown, a synchronous motor 7 is fixedly installed on the outer wall of one of the support plates 6 and on one side of the outer wall of the frame 1. The output ends of the two synchronous motors 7 are fixedly connected to the shaft ends of the movable pressure roller 3 and the fixed pressure roller 2, respectively.

[0039] In this embodiment, the synchronous cylinder 8 facilitates the lifting and lowering of the support plate 6, which in turn drives the movable pressure roller 3 to move.

[0040] Working principle: In use, start the two synchronous cylinders 8 on the frame 1 to drive the two support plates 6 to rise and fall synchronously on the corresponding limit frame 6, thereby driving the movable pressure roller 3 to rise and fall, adjusting its distance from the fixed pressure roller 2. Start the limiting motor 406 to drive the bidirectional screw 401 to rotate, driving the threaded block 403 to move. With the help of the limit rod 402 and the limit block 404, the two limit frames 405 are driven to move closer or further apart, adjusting the distance between the two limit frames 405. After adjustment, pass one end of the base film coated with primer through the fixed pressure roller 2 and the movable pressure roller 3, spread the silicone raw material on the base film, start the two synchronous motors 7 to drive the fixed pressure roller 2 and the movable pressure roller 3 to calender the silicone raw material.
