Description

Technical Field

[0001] This application relates to the field of rubber processing technology, and in particular to a rubber mixing and processing equipment and its processing technology. Background Technology

[0002] Rubber is an elastic polymer. In its production process, it is made by mixing raw rubber with various additives and then processing the mixture using rubber mixing equipment such as internal mixers and open mills.

[0003] Some existing open mills mainly consist of a front roller and a rear roller, such as Figure 9 As shown, the two rollers are hollow. In use, high-temperature steam is introduced into the rollers, and the rubber compound processed by the internal mixer is placed on the upper side between the two rollers. Then, the two rollers are rotated at a relative speed, causing the rubber compound to be drawn into the gap between the two rollers and cover the surface of the front roller. Then, the additive is poured onto the surface of the rubber compound, so that the additive is squeezed and sheared by the rollers and mixed into the rubber compound. Through the above actions, the purpose of mixing the rubber is achieved. At the same time, in order to speed up the mixing efficiency, the covered rubber compound is usually cut manually. As the rollers continue to rotate, the cut rubber compound accumulates between the two rollers and wraps the additive that was originally on its surface. Then, the accumulated rubber compound is squeezed and sheared by the rollers again. Through the above actions, the mixing efficiency of the rubber compound is accelerated.

[0004] However, during the manual cutting of the rubber compound, the roller rotates continuously, and since manual cutting can only cut one location of the rubber compound per unit time, the efficiency of rubber compound mixing is affected. Summary of the Invention

[0034] Please refer to Figure 1 , Figure 2 and Figure 3The upper side of the first rotating plate 4 is hinged to the upper inner wall of the first space 3. A second space 7 is provided inside the mounting base 1 at the right side of the roller 2. A lifting rod 8 (such as a combination of a hydraulic cylinder and an output rod in the prior art) is fixedly installed on the bottom surface of the second space 7. A fixing member 9 is fixedly installed at the upper end of the lifting rod 8. A sliding cavity 10 is provided inside the fixing member 9. A sliding member 11 is slidably engaged in the sliding cavity 10. A second rotating plate 12 is hinged to the side of the sliding member 11 facing the roller 2. The side of the second rotating plate 12 facing the roller 2 is rotatably connected to the rotating shaft 6 at the right side. Before performing the above actions, the lifting rod 8 is moved downwards, causing the right side of the roller 2 to deflect downwards and reach a position similar to... Figure 3 As shown, simultaneously, the deflected roller 2 pulls the second rotating plate 12 and the sliding member 11 via the rotating shaft 6 on the right side, causing the sliding member 11 to partially extend out of the sliding cavity 10. Through the aforementioned inclined roller 2, the adhesive material between the two rollers 2 is moved towards the lower side of roller 2. Simultaneously, through the arrangement of the auger 13, the adhesive material is pushed towards the higher side of roller 2. Through these actions, the adhesive material is moved axially back and forth (since the adhesive material between the two rollers 2 and the auger 13 are in different positions, such as...). Figure 4 As shown), and then fully mix with subsequent additives, thereby improving the mixing efficiency of the rubber compound. Then, when the rubber compound is about to be processed (about to reach the required processing time), the above structure is reset, so that the roller 2 returns to the center and continues to work for a short time. Through this action, the rubber compound on the surface of the front roller 2 is evenly distributed, which facilitates subsequent slicing.

[0035] The rotation direction of the aforementioned screw conveyor 13 blades should be set according to the description in the instruction manual; the attached diagram is for illustrative purposes only.

[0036] A rubber compounding process includes the following steps:

[0037] The first step is to weigh the required amount of rubber additives manually. At the same time, the required amount of carbon black, filler and plasticizer is measured by the auxiliary machine. Then, the above materials are added to the internal mixer for mixing to obtain the rubber compound.

[0038] The second step involves lowering the lifting rod 8, causing the right side of roller 2 to deflect downwards. Simultaneously, the deflected roller 2 pulls the second rotating plate 12 and the sliding member 11 via the rotating shaft 6 on the right side, causing the sliding member 11 to partially extend out of the sliding cavity 10. Then, high-temperature steam is introduced into the hollow cavity of roller 2, and the rubber compound processed by the internal mixer is placed on the upper side between the two rollers 2, heating the rubber compound into a molten state. Next, the two rollers 2 are rotated at a relative differential speed, causing the rubber compound to be drawn into the gap between the two rollers 2 and cover the surface of the front roller 2. Then, accelerators, vulcanizing agents, and hygroscopic agents are poured onto the surface of the rubber compound, allowing the additives to be absorbed. The rubber compound is squeezed and sheared by the roller 2, and then mixed with the rubber compound. At the same time, during the above process, the moving mechanism 14 drives the motor and the auger 13 to move down, so that the auger 13 contacts the rubber compound on the surface of the front roller 2 and cuts and scrapes the rubber compound in multiple places. The cut rubber compound continues to rotate with the roller 2, and then coats the surface accelerator, vulcanizing agent and hygroscopic agent, and drives the accelerator, vulcanizing agent and hygroscopic agent to be processed by the roller 2 again. After that, when the rubber compound is about to be processed, the above structure is reset, so that the roller 2 returns to the center and continues to work for a short time. Through this action, the rubber compound on the surface of the front roller 2 is evenly distributed, which facilitates subsequent slicing.

[0039] The third step is to cut the rammed rubber into strips and pass the strips through a cooling machine and a cooling device to cool them down.

[0040] The fourth step is to suspend the cooled adhesive strip for more than two hours to obtain the second-stage adhesive. Example

[0041] Please see Figure 3 and Figure 5This embodiment is a further improvement on Embodiment 1. The improvement lies in that the rear roller 2 is configured as an annular hollow cavity, and the rotating shaft 6 is located at the center of the annular hollow cavity. A control rod 15 (such as an electro-hydraulic rod in the prior art) is fixedly installed inside the rotating shaft 6. The side of the control rod 15 closest to the roller 2 is fixedly connected to the inner side of the roller 2. During the process of the roller 2 extruding and shearing the rubber material, the control rod 15 is periodically operated, causing the control rod 15 to drive the rear roller 2 to perform radial displacement. Through this action, the distance between the front and rear rollers 2 is intermittently increased, thereby increasing the distance between the front and rear rollers. The rubber material between rollers 2 will be subjected to additional pressing pressure, which will further accelerate the mixing efficiency of the rubber material. At the same time, due to the intermittent increase in the distance between the front and rear rollers 2, the amount of rubber material fed between the two rollers 2 will intermittently increase, which will accelerate the speed at which the rubber material participates in the processing operation of rollers 2, thereby further accelerating the mixing efficiency of the rubber material. In addition, due to the intermittent increase in the amount of rubber material fed, the amount of rubber material distributed on the surface of the front roller 2 will change from more to less and then back to more. As a result, the auger 13 will intermittently increase the cutting amount of the rubber material during the cutting process, which will intermittently increase the mixing degree of the rubber material and additives. Example

[0042] Please see Figure 6 , Figure 7 and Figure 8 This embodiment is a further improvement on embodiment two. The improvement lies in that an elastic element 16 is provided on the inner side of the rear roller 2, with its outer end connected to the inner side of the rear roller 2 and its inner end connected to the rotating shaft 6. A first protrusion 17 is circumferentially and equidistantly fixed on both the left and right sides of the inner side of the rear roller 2. A sleeve 18 is provided on both the first rotating plate 4 and the second rotating plate 12. The sleeve 18 is fitted onto the outer side of the rotating shaft 6 and extends into the center of the rear roller 2. A second protrusion 19 is welded and fixed to the outer side of the sleeve 18. Both the first protrusion 17 and the second protrusion 19 are arc-shaped structures. 17 and 19 are staggered. During the rotation of the roller 2 driven by the rotating shaft 6, 17 rotates synchronously and contacts 19 on the sleeve 18. This causes 17 to cause radial displacement of the roller 2 at the rear position and deform the elastic element 16. Then, as the roller 2 continues to rotate, 17 moves away from 19, causing the elastic element 16 to reset the roller 2 at the rear position. This process is repeated. Since 17 is circumferentially equidistant, the number of radial displacements occurs when the rear roller 2 rotates one revolution, thus increasing the number of times the rubber material is pressed.

[0043] Both the No. 1 rotating plate 4 and the No. 2 rotating plate 12 are equipped with telescopic mechanisms (such as electric telescopic rods in the prior art, not shown in the figure). The telescopic mechanism is connected to the sleeve 18. When the roller 2 returns to the center, the telescopic mechanism drives the sleeve 18 to extend the roller 2 at the rear position, thereby preventing the distance between the two rollers 2 from changing and affecting the subsequent slicing quality.
