Technical Field
[0001] This utility model relates to the field of rubber processing technology, and in particular to an extrusion device for processing compounded rubber. Background Technology
[0002] During rubber compound processing, it needs to be reshaped, a process that utilizes an extruder. To improve compound purity and product quality, and to remove impurities and foreign matter, rubber compound extruders are often equipped with filtration mechanisms. Existing extruders typically achieve filtration by adding a filter screen, usually located at the discharge end. During operation, impurities in the rubber compound accumulate in front of the filter screen. Once this accumulation reaches a certain level, it affects the extrusion of the rubber compound, requiring cleaning to ensure stable equipment operation. However, due to limitations of existing filtration mechanisms, cleaning the filter screen usually requires stopping the machine for disassembly and cleaning. Furthermore, the cleaning time is unpredictable depending on the degree of clogging, significantly reducing work efficiency. Therefore, there is an urgent need for an extrusion device for rubber compound processing that allows for filter screen disassembly and cleaning without stopping the machine. Utility Model Content
[0003] The purpose of this invention is to provide an extrusion device for processing rubber compound, which can achieve one standby and one use.

[0019] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:
[0020] like Figures 1 to 4 As shown, the extrusion equipment for processing compounded rubber according to this utility model includes an extrusion tube 1. A drive motor 2 is provided at one end of the extrusion tube 1. The drive motor 2 is connected to a conveying screw provided inside the extrusion tube 1. A feeding hopper 3 is provided at the top of the extrusion tube 1. A discharge pipe 4 is provided at the end of the extrusion tube 1 away from the drive motor 2. A filter housing 5 is provided between the extrusion tube 1 and the discharge pipe 4. The filter housing 5 is connected at both ends along the axis of the extrusion tube 1. The interior of the filter housing 5 is perpendicular to the axis of the extrusion tube 1. The filter housing 5 is equipped with an arc-shaped filter plate 6 that rotates in the direction of rotation. A drive unit 7 connected to the filter plate 6 is located outside the filter housing 5. The drive unit 7 allows for the rotation adjustment of the filter plate 6. Two filter screens 8 are detachably mounted on the filter plate 6. One filter screen 8 corresponds to the outlet of the discharge pipe 4, and the other filter screen 8 has a maintenance port 9 on the filter housing 5. Two maintenance ports 9 are symmetrically arranged on the filter housing 5, and a maintenance plate 10 is detachably mounted at the maintenance port 9 for disassembling and cleaning the filter screen 8. During operation, when cleaning of the filter screen 8 is required, the drive unit 7 is operated to control the rotation of the filter plate 6, switching between the two filter screens 8. The spare filter screen 8 is rotated to the corresponding position at the outlet of the discharge pipe 4, while the filter screen 8 to be cleaned is rotated to the maintenance port 9. The filter screen 8 can be removed and cleaned by disassembling the maintenance plate 10. The entire operation can be performed without stopping the machine, ensuring work efficiency. During the switching of filter screens 8, the speed of the drive motor 2 can be reduced to decrease resistance during the switching process.
[0021] The two filter screens 8 are arranged at an angle, that is, the two filter screens 8 are asymmetrically set. When one filter screen 8 is in use, the other standby filter screen 8 is located on the side adjacent to the filter screen 8 in use. That is, when working, one filter screen 8 corresponds to the outlet of the discharge pipe 4, and the other filter screen 8 is staggered from the outlet of the discharge pipe 4, so that the two filter screens 8 can be switched by rotating the filter plate 6 by a certain angle.
[0022] Furthermore, each of the upper and lower filter housings 5 of the filter plate 6 is provided with a receiving groove 11, which is arranged along the front and back direction of the filter housing 5. One end of the receiving groove 11 is open, and the shape of the receiving groove 11 matches the shape of the filter plate 6 so that the filter plate 6 can be moved in and out of the receiving groove 11. When one filter screen 8 is located at the outlet of the discharge pipe 4, the other filter screen 8 is located in the receiving groove 11. The inspection port 9 is provided on the filter housing 5 corresponding to the two receiving grooves 11. The receiving groove 11 can temporarily store the spare filter screen 8 to prevent it from coming into contact with the colloid conveyed during operation. In addition, the filter plate 6 is provided with multiple sealing blocks 12. The sealing blocks 12 can be made of high-temperature resistant material, and the thickness of the sealing blocks 12 matches the height of the receiving groove 11 so that it can move in and out of the receiving groove 11 with the filter plate 6. The sealing blocks 12 are used to seal the opening of the receiving groove 11 to prevent the molten colloid transported during operation from entering the receiving groove 11. During operation, the sealing blocks 12 on the filter plate 6 are located at the openings of two receiving grooves 11 respectively. Preferably, the side wall of the receiving groove 11 that is connected to the inspection port 9 can be set to a vacuum structure inside to reduce the heat transferred outward when replacing the filter screen 8 and improve the safety of operation. In addition, the entire filter housing 5 can also be optimized to be a double-wall structure with a vacuum cavity to reduce the heat transferred outward and ensure the safety when replacing the filter screen 8.
[0023] Furthermore, both ends of the filter plate 6 are provided with circular sealing plates 13, and the sealing plates 13 are rotatably connected to the filter housing 5 via a rotating shaft 14. The driving component 7 is preferably a turntable connected to the rotating shaft 14 on the same side, and the filter screen 8 can be switched by rotating the turntable; if the overall size of the machine is large, the driving component 7 can also be driven by a motor to improve the convenience of operation; in this embodiment, a positioning component is provided on the outside of the filter housing 5 to position the rotating shaft 14, ensuring the stability of the filter plate 6 during operation; preferably, the positioning component includes a positioning rod 15 elastically set on the filter housing 5, a guide sleeve 16 is provided on the filter housing 5, the positioning rod 15 is movably set through the guide sleeve 16, and a spring 17 is provided between the positioning rod 15 and the guide sleeve 16, and the spring 17 is sleeved on the outside of the positioning rod 15. A V-shaped positioning plate 18 is provided at the bottom of the positioning rod 15, a positioning gear 19 is coaxially set on the rotating shaft 14, and positioning teeth that mesh with the positioning gear 19 are provided on the positioning plate 18. When it is necessary to rotate the shaft 14 to switch the filter screen 8, simply pull the positioning rod 15 to separate the bottom positioning plate 18 from the positioning gear 19. The operation is simple and quick.
[0024] This utility model, by setting a filter housing 5 between the extrusion pipe and the discharge pipe 4, and rotatably setting a filter plate 6 inside the filter housing 5, can realize the switching of two filter screens 8 by rotating the filter plate 6, thereby realizing the disassembly and replacement of filter screens 8 without stopping the machine, ensuring work efficiency, simple and quick operation, and strong practicality.
