Technical Field

[0001] This utility model relates to the technical field of rubber screening devices, specifically a rubber compound screening device. Background Technology

[0002] Rubber compounds are blended and processed rubber materials that improve their physical and chemical properties by uniformly mixing raw rubber with various additives (such as vulcanizing agents, accelerators, fillers, plasticizers, antioxidants, etc.). Due to their excellent performance and versatility, these materials are widely used in numerous industrial and consumer goods sectors.

[0003] In the existing technology, a screening device is required to screen the compounded rubber to facilitate subsequent production work.

[0004] However, the screening holes on the screening plates of traditional screening devices often become clogged, requiring operators to periodically stop the device to disassemble and clean the screening plates. This increases the workload for operators, is inconvenient for practical use, and requires the device to be shut down for extended periods, resulting in low production efficiency. Therefore, this invention proposes a mixed rubber material screening device to solve the above problems. Utility Model Content

No manual cleaning is required, which is convenient for actual use.

[0027] Example 2

[0028] Based on Embodiment 1, a screening plate 4 is provided for ease of use. The screening plate 4 has a square plate structure. The positioning block 13 fixedly connected to the side of the screening plate 4 is stuck in the mounting groove 5 opened on the inner side of the screening device body 1. A motor 2 is fixedly installed on the side of the screening device body 1. The drive shaft of the motor 2 is fixedly connected to a contact block 3. The side of the contact block 3 contacts the lower moving plate 14. The mounting groove 5 has a "T" shaped groove structure. In the initial state, the shorter side of the contact block 3 contacts the lower moving plate 14. When the motor 2 is started, the contact block 3 is driven to rotate. The longer upper side of the contact block 3 contacts and presses the lower moving plate 14.

[0029] A spring 17 and a connecting column 16 are fixedly connected to the lower moving plate 14. The connecting column 16 has a cylindrical structure. The threaded hole on the connecting column 16 is threadedly connected to the fixing bolt 19. The connecting column 16 can slide along the connecting hole 18 on the screening plate 4. The connecting hole 18 has a circular groove structure, so that the connecting column 16 fixedly connected to the lower moving plate 14 can slide along the connecting hole 18 on the screening plate 4.

[0030] The lower moving plate 14 has a U-shaped plate structure. Several cleaning columns 15 are fixedly connected to the lower moving plate 14. The cleaning columns 15 have a cylindrical structure and correspond to the screening holes opened on the screening plate 4. The cleaning columns 15 can be inserted into the screening holes opened on the screening plate 4 to squeeze out the compound rubber material blocking the screening holes. The contact block 3 continues to rotate and the shorter side contacts the lower moving plate 14. The elastic spring 17 relaxes and pushes the lower moving plate 14, so that the lower moving plate 14 and the connecting column 16 slide along the connecting hole 18. The fixing bolt 19 is used as a limiting device to prevent the connecting column 16 from falling off the screening plate 4. The cleaning column 15 is disengaged from the screening holes opened on the screening plate 4, and the screening plate 4 can continue to screen materials. In this way, the device can automatically clean the screening holes opened on the screening plate 4 without manual cleaning, which is convenient for actual use.

[0031] Example 3

[0032] Based on Embodiment 2, an installation block 6 is provided for easy maintenance. The installation block 6 has a "T"-shaped plate structure and a sliding groove 7 with a "convex" groove structure. A thrust spring 8 is provided in the sliding groove 7. The other end of the thrust spring 8 is fixedly connected to the slider 9. The slider 9 has an "I"-shaped plate structure. One end of the slider 9 is stuck in the sliding groove 7. The operator can pull the slider 9 to slide along the sliding groove 7 to retract the thrust spring 8, so that the fixing block 10 fixedly connected to the slider 9 slides along the square groove 11 and disengages from the slot 12, thereby releasing the lock between the installation block 6 and the main body 1 of the screening device.

[0033] The fixing block 10 has a square plate-like structure and is fixedly connected to the mounting block 6. One end of the fixing block 10 is stuck in the square groove 11 opened on the mounting block 6, and the other end is stuck in the slot 12 opened on the main body 1 of the screening device. Both the slot 12 and the square groove 11 have a square groove-like structure. The mounting block 6 contacts the positioning block 13 fixedly connected to the screening plate 4, which limits the positioning block 13 stuck in the mounting groove 5. The operator can then remove the mounting block 6 from the mounting groove 5. After all the mounting blocks 6 are removed, the handle on the screening plate 4 can be pulled to slide the screening plate 4 and the positioning block 13 along the mounting groove 5. The structure is simple and easy for personnel to use. Furthermore, by unscrewing and removing the fixing bolt 19, the connecting column 16 can be slid out along the connecting hole 18, and the lower moving plate 14 can be removed from the screening plate 4. The structure is simple and easy for personnel to disassemble the device, which is convenient for personnel to maintain or replace the screening plate 4 and for personnel to use.

[0034] Working principle: In actual use, the starting motor 2 drives the contact block 3 to rotate. The longer side of the contact block 3 contacts and presses the lower moving plate 14, causing the connecting column 16 to slide along the connecting hole 18. This causes the cleaning column 15 to be inserted into the screening hole on the screening plate 4, squeezing out the mixed rubber material that is blocked inside. When the shorter side of the contact block 3 contacts the lower moving plate 14, the elastic spring 17 relaxes and pushes the lower moving plate 14, causing the cleaning column 15 to disengage from the screening hole on the screening plate 4. Through the above, the device can automatically clean the screening hole on the screening plate 4 without manual cleaning, which is convenient for personnel to use. Furthermore, by disengaging the fixing block 10 from the slot 12 to release the locking of the mounting block 6, the mounting block 6 can be removed, and the screening plate 4 can be removed from the main body 1 of the screening device, which is convenient for personnel to use.
