Description

Technical Field

[0001] This application relates to the field of mixing equipment technology, and in particular to a mixing equipment for preparing thermally conductive adhesive silicone rubber. Background Technology

[0002] Rubber is a product commonly used in people's production and daily life. During the production process, rubber needs to be mixed. Existing mixing machines use the rotation of two relatively rotating rollers to create friction and adhesion forces on the rubber compound, thereby shearing and crushing the rubber compound in the gap between the two rollers.

[0003] The existing Chinese patent (authorization announcement number: CN222309399U) mentions a preparation equipment for silicone rubber mixing. Through the interaction of a supporting base plate, a first frame plate, a second frame plate, a first extrusion roller, a second extrusion roller, two movable plates, and an adjusting and moving component, the distance between the two baffles on the silicone rubber mixing equipment can be easily adjusted during use, so as to facilitate better operation and achieve better practicality.

[0004] The existing method of mixing rubber simply involves placing the rubber between two extrusion rollers. While this is simple and easy, the thermally conductive adhesive silicone rubber itself has a certain degree of stickiness, especially during the mixing process when it is in an uncured state. This stickiness can cause it to adhere to the surface of the guide rollers, which means that after processing, workers may need to manually clean the surface of the extrusion rollers with tools such as scrapers, which is quite inconvenient. Utility Model Content

[0005] The purpose of this application is to provide a mixing equipment for preparing thermally conductive adhesive silicone rubber, in order to solve the problem that workers may need to manually clean the surface of the extrusion rollers using tools such as scrapers after processing.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A mixing apparatus for preparing thermally conductive adhesive silicone rubber includes a support frame. A working groove is formed on the inner side of the support frame. An extrusion roller is symmetrically and rotatably connected to the inner side of the working groove. A rotary motor is fixedly connected to the outer side of the support frame. The output shaft of the rotary motor passes through the support frame and is fixedly connected to one extrusion roller. A gear one is fixedly connected to the outer side of the output shaft of the rotary motor. A gear two is meshed with the outer side of gear one. A connecting rod is fixedly connected to the inner side of gear two. One end of the connecting rod passes through the support frame and is fixedly connected to another extrusion roller. A cleaning mechanism is provided at the top of the support frame.

[0008] By adopting the above technical solution, the rotary motor is first turned on, which drives one extrusion roller to start rotating. At the same time, the gear starts to rotate. Through the meshing connection between gear one and gear two, gear two is driven to rotate. At this time, the thermally conductive adhesive silicone rubber material is placed into the gap between the two extrusion rollers. As the extrusion rollers rotate relative to each other, friction and adhesion are generated on the rubber material, which in turn causes the rubber material to be subjected to shearing and crushing action. The cleaning mechanism makes it convenient for workers to clean the extrusion rollers.

[0009] Furthermore, the cleaning mechanism includes two threaded blocks symmetrically slidably disposed on the top of the support frame. A movable block is fixedly connected to the outer side of the threaded block, and a cleaning block is fixedly connected to the bottom of the movable block. The cleaning block is configured as an annular shape, and a scraper is fixedly connected to the inner side of the cleaning block. A driving component is provided on the top of the support frame.

[0010] By adopting the above technical solution, the movement of the threaded block drives the movement of the moving block, the movement of the moving block drives the movement of the cleaning block, and the movement of the cleaning block will drive the scraper to clean the outside of the extrusion roller.

[0011] Furthermore, the driving component includes a support block symmetrically fixedly connected to the top of the support frame. A movable frame is fixedly connected to the top of the support block. A drive motor is fixedly connected to the outer side of the movable frame. The output shaft of the drive motor passes through the movable frame and is fixedly connected to a bidirectional threaded rod. One end of the bidirectional threaded rod passes through two threaded blocks, and the bidirectional threaded rod is threadedly connected to the threaded blocks.

[0012] By adopting the above technical solution, the drive motor is started to drive the bidirectional threaded rod to rotate, and the two threaded blocks are connected to the bidirectional threaded rod through the threaded block, so that the two threaded blocks can move relative to each other.

[0013] Furthermore, a placement plate is fixedly connected to the inner side of the working groove. The placement plate is L-shaped, and a placement box is slidably connected to the top of the placement plate. The top of the placement box is open, and connecting blocks are symmetrically fixedly connected to the outer side of the placement box.

[0014] By adopting the above technical solution, the scraped rubber residue will fall downwards. With the top of the placement box being open, the rubber will enter the placement box for storage, reducing its scattering around the equipment or on the workbench.

[0015] Furthermore, the outer side of the support frame is symmetrically fixedly connected with a connecting frame, the connecting frame and the connecting block are slidably arranged, the top of the connecting frame is threadedly connected with a threaded rod two, the top of the threaded rod two is fixedly connected with a knob, the bottom end of the threaded rod two passes through the connecting frame and is rotatably connected with a pressing block, the pressing block abuts against the connecting block when it moves.

[0016] By adopting the above technical solution, rotating the knob causes the pressing block to press down against the connecting block, thereby fixing the connecting block, and fixing the connecting block will fix the placement box.

[0017] Furthermore, a metal plate is fixedly connected to the bottom of the extrusion block, and the bottom of the metal plate is set with a rough metal surface.

[0018] By adopting the above technical solution, the rough surface of the metal plate increases the friction between the extrusion block and the connecting block.

[0019] In summary, this application includes at least one of the following beneficial effects;

[0020] 1. In this application, when cleaning the extrusion roller, the drive motor is first started to drive the scraper to clean the outside of the extrusion roller, eliminating the need for manual cleaning of the outside of the extrusion roller, thus improving cleaning efficiency and reducing the workload of the workers.

[0021] 2. In this application, when cleaning the extrusion roller, the scraped rubber residue will fall downwards into the storage box for storage, reducing its scattering around the equipment or on the workbench, helping to maintain a clean working environment, and further reducing the difficulty of cleaning.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a mixing equipment for preparing thermally conductive adhesive silicone rubber.

[0030] Reference Figure 1 A mixing device for preparing thermally conductive adhesive silicone rubber includes a support frame 1. A working groove 2 is provided on the inner side of the support frame 1. An extrusion roller 4 is symmetrically rotatably connected to the inner side of the working groove 2. A rotary motor 3 is fixedly connected to the outer side of the support frame 1. The output shaft of the rotary motor 3 passes through the support frame 1 and is fixedly connected to one of the extrusion rollers 4. A gear 5 is fixedly connected to the outer side of the output shaft of the rotary motor 3. A gear 6 is meshed with the outer side of the gear 5. A connecting rod is fixedly connected to the inner side of the gear 6. One end of the connecting rod passes through the support frame 1 and is fixedly connected to another extrusion roller 4. A cleaning mechanism is provided on the top of the support frame 1.

[0031] When mixing rubber, the rotary motor 3 is turned on first, which drives one extrusion roller 4 to start rotating. At the same time, gear 5 starts rotating. Gear 5 meshes with gear 6, driving gear 6 to rotate. The two extrusion rollers 4 rotate in opposite directions, forming a gap between them. At this time, the thermally conductive adhesive silicone rubber material is placed into the gap between the two extrusion rollers 4. As the extrusion rollers 4 rotate relative to each other, friction and adhesion are generated on the rubber material, which in turn causes the rubber material to be subjected to shearing and crushing. The cleaning mechanism allows workers to easily clean the extrusion rollers 4.

[0032] Reference Figures 1 to 3 The cleaning mechanism includes two threaded blocks 11 that are symmetrically slidably disposed on the top of the support frame 1. A movable block 12 is fixedly connected to the outer side of the threaded block 11, and a cleaning block 14 is fixedly connected to the bottom of the movable block 12. The cleaning block 14 is ring-shaped, and a scraper 15 is fixedly connected to the inner side of the cleaning block 14. A driving component is provided on the top of the support frame 1.

[0033] The driving component includes a support block 7 that is symmetrically fixedly connected to the top of the support frame 1. A movable frame 8 is fixedly connected to the top of the support block 7. A drive motor 9 is fixedly connected to the outside of the movable frame 8. The output shaft of the drive motor 9 passes through the movable frame 8 and is fixedly connected to a bidirectional threaded rod 10. One end of the bidirectional threaded rod 10 passes through two threaded blocks 11, and the bidirectional threaded rod 10 is threadedly connected to the threaded blocks 11.

[0034] When cleaning the extrusion roller 4, the drive motor 9 is first started to drive the bidirectional threaded rod 10 to rotate. The threaded block 11 is threadedly connected to the bidirectional threaded rod 10, so that the two threaded blocks 11 move relative to each other. The movement of the threaded block 11 drives the moving block 12 to move, and the movement of the moving block 12 drives the cleaning block 14 to move. The movement of the cleaning block 14 will drive the scraper 15 to clean the outside of the extrusion roller 4. There is no need for manual cleaning of the outside of the extrusion roller 4, which improves the cleaning efficiency and reduces the workload of the staff.

[0035] Reference Figure 1 , Figure 3 and Figure 4 The inner side of the working groove 2 is fixedly connected to a placement plate 17, which is L-shaped. The top of the placement plate 17 is slidably connected to a placement box 18, which is open at the top. The outer side of the placement box 18 is symmetrically fixedly connected to a connecting block 19.

[0036] Among them, the outer side of the support frame 1 is symmetrically fixedly connected with a connecting frame 20. The connecting frame 20 and the connecting block 19 are slidably arranged. The top of the connecting frame 20 is threadedly connected with a threaded rod 21. The top of the threaded rod 21 is fixedly connected with a knob 22. The bottom end of the threaded rod 21 passes through the connecting frame 20 and is rotatably connected with a pressing block 23. When the pressing block 23 moves, it abuts against the connecting block 19.

[0037] In addition, a metal plate 24 is fixedly connected to the bottom of the extrusion block 23, and the bottom of the metal plate 24 is set with a rough metal surface.

[0038] When cleaning the extrusion roller 4, the scraped rubber residue will fall downwards. The top of the placement box 18 is designed to be open, allowing the rubber to enter the placement box 18 for storage. This reduces the amount of rubber scattered around the equipment or on the workbench, helps to keep the working environment clean, and further reduces the difficulty of cleaning. When a certain amount has been stored, the placement box 18 can be pulled out for cleaning by moving it on the placement plate 17.

[0039] When the placement box 18 is installed, the placement box 18 drives the connecting block 19 into the connecting frame 20. At this time, by rotating the knob 22, the threaded rod 21 moves downward. The threaded rod moves downward, causing the extrusion block 23 to press against the connecting block 19, thereby fixing the connecting block 19. Fixing the connecting block 19 will fix the placement box 18, reducing the risk of shaking or displacement of the placement box 18 during operation and improving the stability of the placement box 18 when collecting rubber.

[0040] When the abutting block is fixed to the connecting block 19, the rough metal surface of the metal plate 24 increases the friction between the pressing block 23 and the connecting block 19, further improving the fixing effect of the connecting block 19.

[0041] Working principle: When the rotary motor 3 is turned on, it drives one of the extrusion rollers 4 to rotate. At the same time, gear 5 starts to rotate. Gear 5 meshes with gear 6, driving gear 6 to rotate. The two extrusion rollers 4 rotate in opposite directions, forming a gap between them. At this time, the thermally conductive adhesive silicone rubber material is placed into the gap between the two extrusion rollers 4. As the extrusion rollers 4 rotate relative to each other, friction and adhesion are generated on the rubber material, which in turn causes the rubber material to be subjected to shearing and crushing. The drive motor 9 is started to drive the bidirectional threaded rod 10 to rotate. The threaded block 11 is threadedly connected to the bidirectional threaded rod 10, causing the two threaded blocks 11 to move relative to each other. The movement of the threaded block 11 drives the movement block 12 to move, and the movement of the movement block 12 drives the cleaning block 14 to move. The movement of the cleaning block 14 will drive the scraper 15 to clean the outside of the extrusion roller 4.
