Description

Technical Field

[0001] This utility model relates to the field of rubber mat production technology, specifically a raw material screening device for rubber production. Background Technology

[0002] Rubber products refer to the activities of producing various rubber products using natural and synthetic rubber as raw materials. This also includes rubber products manufactured from recycled waste rubber. The production volume of synthetic rubber has far exceeded that of natural rubber, with styrene-butadiene rubber (SBR) having the largest production volume. While there are many types of rubber products, their production processes are basically the same. The basic process for producing rubber products using general solid raw rubber as raw material includes six basic steps: plasticizing, mixing, calendering, extrusion, molding, and vulcanization.

[0003] In the existing raw material screening process for rubber products, the conventional operation is to place the raw material directly on a fixed screening mesh or screening plate for screening. Since the screening device adopts a static structural design, when the amount of raw material fed is too large, the fine particles on the top of the accumulation layer are easily blocked by the physical barrier formed by the large particles at the bottom, which prevents them from fully contacting the screening interface. This blocking effect between particle levels will significantly reduce the screening efficiency, which may affect the quality of the final product.

[0004] Therefore, this utility model provides a raw material screening device for rubber production to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a raw material screening device for rubber production, such as... Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the raw material screening device for rubber production includes a base plate 1, a support frame 2 fixedly installed on the base plate 1, a housing 3 set on the support frame 2, a feed pipe 4 fixedly installed on the housing 3, a screen 5 fixedly installed inside the housing 3, and a shaking mechanism set on the support frame 2 for more thorough screening of rubber raw materials.

[0026] The swaying mechanism includes a motor 6 fixedly mounted on the support frame 2, a sleeve 7 fixedly mounted on the output end of the motor 6, a guide block 8 fixedly mounted inside the sleeve 7, a moving rod 9 slidably mounted inside the sleeve 7, a fixing block 10 fixedly mounted on the moving rod 9, and a push plate 11 fixedly mounted on the moving rod 9. One side of the push plate 11 is in contact with one side of the housing 3.

[0027] When using this raw material screening device for rubber production, the base plate 1 is first placed in a suitable position. Then, the rubber raw material is added into the interior of the shell 3 through the feed pipe 4. The rubber raw material first falls onto the screen 5 with larger filter holes. By starting the motor 6, the rotation of the motor 6 drives the sleeve 7 to rotate synchronously. The rotation of the sleeve 7 drives the guide block 8 to rotate synchronously. Since the two fixed blocks 10 are set inside the slide rail formed between the two guide blocks 8, when the two guide blocks 8 rotate, they drive the fixed blocks 10 to move synchronously along the slide rail. The movement of the fixed blocks 10 drives the moving rod 9 to move synchronously, thereby driving the push plate 11 to move synchronously. This causes the push plate 11 to drive the shell 3 to move synchronously. The movement of the shell 3 causes the rubber raw material inside to shake. When the amount of rubber raw material added is too large, it reduces the situation where the fine particles on the top of the accumulation layer are blocked by the large particles at the bottom, so that the rubber raw material can fully contact the screen 5, improving the screening efficiency and thus improving the quality of the final product.

[0028] Furthermore, in order to achieve a shaking effect between the housing 3 and the screen 5 inside the housing 3, such as... Figure 1 , Figure 2 and Figure 3 As shown, a plurality of limiting blocks 12 are fixedly connected to one side of the support frame 2, and a limiting post 13 is fixedly connected to the opposite side of two limiting blocks 12. A spring 14 is sleeved on the side surface of the limiting post 13.

[0029] The housing 3 is fixedly connected to the two sides of the first connecting block 15. The first connecting block 15 is slidably connected to the side surface of the limiting post 13. One end of the spring 14 is fixedly connected to one side of the limiting block 12, and the other end of the spring 14 is fixedly connected to one side of the first connecting block 15.

[0030] When in use, the raw material screening device for rubber production works by starting the motor 6. The rotation of the output shaft of the motor 6 drives the push plate 11 to reciprocate. The reciprocating movement of the push plate 11 drives the housing 3 to move synchronously. The movement of the housing 3 drives the first connecting blocks 15 on both sides to move along the limiting post 13. The movement of the limiting post 13 compresses the spring 14. When the push plate 11 moves back, the elastic potential energy of the spring 14 causes the housing 3 and the first connecting blocks 15 to move in the opposite direction, thereby achieving a shaking effect and ultimately achieving full screening of the rubber raw materials.

[0031] In order to facilitate the collection and screening of good rubber raw materials, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first electric push rod 16 is fixedly connected inside the housing 3, and a pusher plate 17 is fixedly connected to the movable end of the first electric push rod 16. The bottom of the pusher plate 17 is in contact with the top of the screen 5.

[0032] A discharge plate 18 is fixedly connected to one side of the housing 3, a guide plate 19 is fixedly connected to the bottom of the housing 3, a second electric push rod 20 is fixedly connected to the bottom of the housing 3, a second connecting block 21 is fixedly connected to the movable end of the second electric push rod 20, a baffle 22 is fixedly connected to the top of the second connecting block 21, and sliders 23 are fixedly connected to both sides of the baffle 22.

[0033] Both sides of the housing 3 are provided with sliding grooves 24 for sliding slider 23. The top of baffle 22 contacts the bottom of guide plate 19. The top of the bottom plate 1 is movably connected to a collection box 25, which is located at the bottom of guide plate 19.

[0034] When the raw material screening device for rubber production is in use, after the rubber raw material is screened through multiple screens 5 with different filter hole sizes, the first electric push rod 16 is activated. The movable end of the first electric push rod 16 drives the pusher plate 17 connected to it to move synchronously. The movement of the pusher plate 17 pushes the rubber raw material on the screen 5 to the discharge plate 18, and then collects the rubber raw material. At the same time, the second electric push rod 20 is activated. Through the cooperation of the slider 23 and the chute 24, the movable end of the second electric push rod 20 drives the second connecting block 21 and the baffle 22 connected to it to move synchronously along the chute 24. Finally, the rubber raw material inside the guide plate 19 flows out and falls into the collection box 25, completing the collection of the screened rubber raw material.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
