Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing, in particular to a rubber mixing device for rubber plate production and processing. Background Technique

[0002] When producing rubber plates, a rubber mixer is required. The working principle of the rubber mixer is to extrude, shear and mix rubber raw materials through two relatively rotating rollers. During the rubber mixing process, the rubber raw materials are placed between the two rollers. As the rollers rotate, the rubber is subjected to extrusion and shear forces, causing the molecular chains to break and rearrange, thereby achieving the purpose of plasticating and mixing. Specifically, the working principle of the rubber mixer includes the following aspects: 1. Extrusion effect: The rollers apply pressure to the rubber raw materials, making them thinner and increasing the contact area, which is beneficial to subsequent mixing and chemical reactions. 2. Shearing effect: The relative rotation of the rollers generates shear forces, dividing the rubber raw materials into small parts and making them flow and mix repeatedly between the rollers, promoting the uniform distribution of various components.

[0003] At present, there are certain defects in the rubber mixing operation of the rubber mixer:

[0004] 1. During the mixing process of rubber raw materials on the surface of the rollers, it is necessary to manually pull and scrape the rubber scraping board repeatedly, which is time-consuming and laborious, the operation is relatively cumbersome, and the degree of automation is relatively low.

[0035] Please refer to Figures 1-5 , the present utility model provides a technical solution: a rubber sheet production and processing rubber mixing device, including a base 1.

[0036] The top of the base 1 is integrally connected with a U-shaped frame 2 and two groups of support platforms 3. The tops of the two groups of support platforms 3 are respectively fixedly connected with a double-output reduction gear 4 and a driving motor 5. The output end of the driving motor 5 is connected to the input end of the double-output reduction gear 4.

[0037] A transmission roller 6 and an auxiliary roller 7 are rotatably installed inside the U-shaped frame 2. The transmission roller 6 and the auxiliary roller 7 are connected to the two output ends of the double-output reduction gear 4, and the transmission roller 6 and the auxiliary roller 7 are arranged in parallel. A back frame 8 is integrally connected to the rear side of the U-shaped frame 2. A motor slot 9 is opened inside the back frame 8, and two groups of sliding slots 15 are opened inside the front side of the back frame 8.

[0038] One end of the motor slot 9 is fixedly connected with a servo motor 10, and the other end of the motor slot 9 is fixedly connected with a bearing seat 11. The motor shaft of the servo motor 10 is fixedly connected with a transmission rod 12. The end of the transmission rod 12 away from the servo motor 10 is fixed in the inner ring of the bearing of the bearing seat 11. The transmission rod 12 is provided with a first thread 13 and a second thread 14, and two groups of sliders 16 are movably sleeved on the transmission rod 12. The top of one group of sliders 16 is fixedly connected with an upper connecting frame 17, and the bottom of the other group of sliders 16 is fixedly connected with a lower connecting frame 18. The upper connecting frame 17 is fixedly connected with an upper scraping blade 19 on the outside of the back frame 8, and the lower connecting frame 18 is fixedly connected with a lower scraping blade 20 on the outside of the back frame 8.

[0039] The upper connecting frame 17 and the lower connecting frame 18 are both "L" shaped structures, and the width of the upper end of the upper connecting frame 17 and the width of the lower end of the lower connecting frame 18 are evenly matched with the width of the slide groove 15. Specifically, the two groups of slide grooves 15 are connected to the motor slot 9, and the slide groove 15 has a positioning function for the upper connecting frame 17 and the lower connecting frame 18, so that the upper connecting frame 17 and the lower connecting frame 18 can run stably in the slide groove 15, ensuring the smooth movement of the upper and lower scrapers, and further improving the automation degree of the equipment and the simplicity of operation.

[0040] The first thread 13 and the second thread 14 are mirror images, and the thread directions of the first thread 13 and the second thread 14 are opposite. The first thread 13 and the second thread 14 are connected to the inner walls of the two sets of sliders 16 through a thread structure. Figure 3 The servo motor 10 can drive the transmission rod 12 to rotate, so that through the thread transmission action of the first thread 13 and the second thread 14, the two groups of sliders 16 can move in opposite horizontal directions, that is, the two groups of sliders 16 move closer to each other or move away from each other, thereby ensuring that the upper scraper 19 and the lower scraper 20 move closer to each other or move away from each other. Automatic scraping of glue is achieved through the upper scraper 19 and the lower scraper 20, and there is no need to manually pull the scraper plate, which solves the time-consuming, labor-intensive and cumbersome operation problems in the prior art and improves work efficiency.

The upper scraper 19 is movably connected to the upper ends of the drive roller 6 and the auxiliary roller 7, and the lower scraper 20 is movably connected to the lower ends of the drive roller 6 and the auxiliary roller 7. Figure 4 The arc-shaped structural design of the upper scraper blade 19 and the lower scraper blade 20 enables the upper scraper blade 19 and the lower scraper blade 20 to contact and connect with the driving roller 6 and the auxiliary roller 7, ensuring the smoothness of the scraping process and improving the scraping effect.

Specifically, through the design of the feeding hopper 22 and the feeding inclined hole 21, the staff can load the raw material particles into the feeding hopper 22, avoiding the danger of the staff having to contact two relatively rotating rollers at close range when manually loading, significantly improving the safety of the operation, reducing safety hazards, and the raw materials in the feeding hopper 22 are discharged through the feeding inclined hole 21, the lower part of the feeding inclined hole 21 is directly opposite to the position between the driving roller 6 and the auxiliary roller 7, and the raw materials are always dropped to the area between the upper scraper blade 19 and the lower scraper blade 20 after being discharged, which ensures that the materials will not be dropped outside the scraping range of the upper scraper blade 19 and the lower scraper blade 20.

[0043] Specifically, during use, the driving motor 5 and the double-output speed reducer 4 drive the driving roller 6 and the auxiliary roller 7 to rotate. The staff can pour the rubber particle raw material into the feeding hopper 22. The raw material in the feeding hopper 22 is discharged onto the driving roller 6 and the auxiliary roller 7 through the feeding inclined holes 21. Along with the two relatively rotating rollers of the driving roller 6 and the auxiliary roller 7, the rubber raw material is extruded, sheared, and mixed, so as to achieve the purpose of plasticizing and mixing. The servo motor 10 can drive the transmission rod 12 to rotate, thereby driving the upper scraping blade 19 and the lower scraping blade 20 to move closer to or away from each other. During the process of the upper scraping blade 19 and the lower scraping blade 20 moving closer to each other, along with the rotation of the driving roller 6 and the auxiliary roller 7, the upper scraping blade 19 and the lower scraping blade 20 scrape the rubber compound adsorbed on the driving roller 6 and the auxiliary roller 7 towards the center direction, realizing automatic rubber scraping and material turning through the upper scraping blade 19 and the lower scraping blade 20, and ensuring the uniform mixing of the rubber raw material on the surfaces of the driving roller 6 and the auxiliary roller 7.
