Description

Technical Field

[0001] This utility model relates to the field of calendering technology, specifically a calendering machine for producing thermally conductive silicone gaskets. Background Art

[0002] Thermally conductive silicone pads are thermally conductive media materials made from silicone as the base material, with the addition of various auxiliary materials such as metal oxides. In the industry, they are also known as thermally conductive silicone mats or thermally conductive silicone pad sheets. During processing, a calendering operation is typically required.

[0003] In the past, the two pressure rollers used in calendering operations were mostly fixed, which could not enable calendering operations of thermally conductive silicone pads to different thicknesses. To solve this technical problem, the existing technology provides a fully automatic calender for the production of thermally conductive silicone pads, CN213972190U. By setting up a lifting component and a through hole to drive the second pressure roller to move up and down, the distance between the first and second pressure rollers can be adjusted, and under the drive of a motor, it can enable calendering operations of thermally conductive silicone pads to different thicknesses.

[0004] However, there are also some technical problems in its use. For example, the vertical plate inside the device and the lower end of the No. 2 motor are both fixedly connected to lifting components. If, due to some accident, one of the cylinders in the two lifting components is delayed in extending when pushing the push plate upward, the movement between the two cylinders will be asynchronous, causing the No. 2 rotating shaft to tilt, affecting the normal use of the device or causing damage to the device.

[0006] To address the shortcomings of existing technologies, this utility model provides a calendering machine for producing thermally conductive silicone gaskets, thus solving the aforementioned technical problems.

[0007] (2) Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a calender for producing thermally conductive silicone gaskets, comprising a device base, a frame on the top of the device base, two symmetrical mounting brackets slidably mounted on the frame, calendering rollers rotatably mounted on the mounting brackets, transmission cavities on both sides of the frame, a transmission gear rotatably mounted at the center of the transmission cavity, two transmission sliders slidably arranged within the transmission cavity, each transmission slider having a toothed groove meshing with the transmission gear, and two transmission sliders with the furthest distance between them symmetrically mounted on the same mounting bracket, a rotating motor being installed in each of the two mounting brackets, one end of the calendering roller being mounted on the power output shaft of the rotating motor, and a hydraulic telescopic rod being installed on the top of the frame, the actuation output shaft of the hydraulic telescopic rod passing through the frame and mounted on one of the mounting brackets.

[0009] Preferably, two mutually symmetrical limiting grooves are provided on the inner walls of both transmission cavities, and the transmission slider passes through the limiting grooves and is connected to the mounting bracket.

[0010] Preferably, each of the two transmission cavities is provided with two fixed plates, and a guide rod is protruding from the fixed plate, with the transmission slider slidably arranged on the guide rod.

[0011] Preferably, a return spring is sleeved on the guide rod, with one end of the return spring abutting against the fixed plate and the other end of the return spring abutting against the transmission slider.

[0012] Preferably, the mounting frame has a protruding mounting plate, and two slide rods are slidably mounted on the mounting plate. A scraper is provided at one end of the two slide rods near the calendering roller, and a handle is provided at the other end of the two slide rods.

[0013] Preferably, a compression spring is sleeved on the slide rod, and one end of the compression spring abuts against the scraper.

[0014] Preferably, the end of the scraper away from the mounting plate abuts against the surface of the calender roll.

[0015] Compared with the prior art, this utility model provides a calendering machine for producing thermally conductive silicone pads, which has the following advantages:

[0016] 1. This utility model, through the provision of a hydraulic telescopic rod, transmission gears, and transmission sliders, enables the uppermost mounting frame to descend vertically during the calendering of thermally conductive silicone pads. This, in turn, causes the uppermost transmission sliders in the two transmission chambers within the frame to descend vertically, rotating the transmission gears within those chambers. Consequently, the transmission gears drive the other transmission slider in the transmission chamber to rise vertically, bringing the calendering rollers on the two mounting frames closer together and enabling calendering operations of different thicknesses on the thermally conductive silicone pads.

[0025] Please see Figure 1-4 A calender for producing thermally conductive silicone pads includes a base 1, a frame 2 on the top of the base 1, two symmetrical mounting brackets 4 slidingly mounted on the frame 2, calendering rollers 14 rotatably mounted on the mounting brackets 4, transmission cavities 10 on both sides of the frame 2, a transmission gear 16 rotatably mounted at the center of the transmission cavity 10, two transmission sliders 15 slidingly arranged inside the transmission cavity 10, each transmission slider 15 having a toothed groove that meshes with the transmission gear 16, and each pair of transmission sliders 15 with the furthest distance between them symmetrically mounted on the same mounting bracket 4, a rotary motor 13 installed in each of the two mounting brackets 4, one end of the calendering roller 14 mounted on the power output shaft of the rotary motor 13, and a hydraulic telescopic rod 3 on the top of the frame 2, the actuation output shaft of the hydraulic telescopic rod 3 passing through the frame 2 and mounted on one of the mounting brackets 4.

[0026] By incorporating a hydraulic telescopic rod 3, a transmission gear 16, and a transmission slider 15, the uppermost mounting frame 4 can be vertically lowered during the calendering of the thermally conductive silicone pad. This causes the upper transmission slider 15 within the two transmission chambers 10 of the frame 2 to move vertically downward, rotating the transmission gear 16 within the two transmission chambers 10. Consequently, the transmission gear 16 drives the other transmission slider 15 within the transmission chamber 10 to move vertically upward, bringing the calendering rollers 14 on the two mounting frames 4 closer together and enabling calendering operations of different thicknesses on the thermally conductive silicone pad.

[0027] Specifically, in this embodiment, two mutually symmetrical limiting grooves 11 are provided on the inner walls of the two transmission cavities 10, and the transmission slider 15 passes through the limiting grooves 11 and is connected to the mounting bracket 4.

[0028] The movement range of the transmission slider 15 can be limited by the provided limiting groove 11.

[0029] Specifically, in this embodiment, two fixed plates 17 are provided in each of the two transmission cavities 10. A guide rod 18 is protruding on the fixed plate 17. The transmission slider 15 is slidably arranged on the guide rod 18. A return spring 12 is sleeved on the guide rod 18. One end of the return spring 12 abuts against the fixed plate 17, and the other end of the return spring 12 abuts against the transmission slider 15.

[0030] The guide rod 18 guides the movement direction of the transmission slider 15, making the movement of the transmission slider 15 smoother. The return spring 12 facilitates the automatic reset of the transmission slider 15.

[0031] Specifically, in this embodiment, the mounting bracket 4 is provided with a mounting plate 5, and two slide rods 8 are slidably mounted on the mounting plate 5. A scraper 7 is provided at one end of the two slide rods 8 near the calendering roller 14, and a handle 6 is provided at the other end of the two slide rods 8. A compression spring 9 is sleeved on the slide rod 8, one end of the compression spring 9 abuts against the scraper 7, and the end of the scraper 7 away from the mounting plate 5 abuts against the surface of the calendering roller 14.

[0032] The provided spring 9 ensures that the scraper 7 is always pressed against the surface of the calender roll 14, thereby scraping off the material adhering to the surface of the calender roll 14 and ensuring the calendering effect.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
