Description

Technical Field

[0001] This utility model belongs to the field of feeding devices, specifically a feeding device for a rubber internal mixer. Background Technology

[0002] A rubber internal mixer is an industrial equipment used for mixing and processing rubber. Its main function is to uniformly mix raw materials and make them achieve the required physical and chemical properties. The internal mixer feeding equipment is used to accurately feed raw materials into the internal mixer to ensure the stability of the production process and the uniformity of the product.

[0003] According to application number 202123217802.2, a feeding device for a rubber internal mixer is disclosed, including a mixing chamber body, a stirring motor, a stirring shaft, stirring blades, and a feeding hopper. The stirring motor is installed on the surface of the mixing chamber body, the stirring shaft is set on the output shaft of the stirring motor, the stirring blades are installed on the outside of the stirring shaft, and a through hole is opened at the top of the mixing chamber body. The feeding hopper is slidably connected inside the through hole. This comparative example, by setting a support component and a striking structure, can use the stirring shaft as a power input to strike the feeding hopper when the stirring motor drives the stirring shaft and stirring blades to rotate, so that the feeding hopper can generate vibration, thereby improving the feeding of the feeding hopper.

[0004] This comparative case effectively solves the problem that when rubber materials are fed into a rubber mixer through a hopper, the rubber material adheres to the inner wall of the hopper, resulting in a slow feeding speed and thus affecting production efficiency. However, the method of ensuring feeding efficiency by continuously striking the hopper with a striking component not only generates noise but also causes some damage, affecting its service life.

[0005] In summary, this utility model provides a feeding device for a rubber internal mixer to solve the above problems. Utility Model Content

[0022] Example 1

[0023] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a feeding device for a rubber internal mixer, including a mixing box 1. The top of the mixing box 1 is movably connected to a rotating plate 2 via a bearing. The top of the rotating plate 2 is fixedly connected to a feeding hopper 3. The bottom of the mixing box 1 is fixedly connected to a discharge hopper 4. The inner cavity of the mixing box 1 is provided with a scraping mechanism 5. The scraping mechanism 5 includes a fixing ring 501, which is disposed at the upper and lower ends of the inner cavity of the mixing box 1. Connecting plates 502 are fixedly connected to both sides between the two fixing rings 501. Scrapers 503 are fixedly connected to both the front and back sides between the two connecting plates 502. A stirring blade 504 is fixedly connected to the upper and lower ends of the side of the two connecting plates 502 that are close to each other. A support ring 6 is fixedly connected to the surface of the mixing box 1. Fixing plates 7 are fixedly connected to both sides of the support ring 6.

[0024] like Figure 1-4As shown, the mixing tank 1 serves as a transition for added raw materials and provides a mixing space. The rotating plate 2 supports the feeding hopper 3, which facilitates the addition of components into the mixing tank 1. The discharge hopper 4 is inserted into the feeding port of the internal mixer to add the raw materials from the mixing tank 1 into the internal mixer, achieving the purpose of feeding. The scraping mechanism 5 can stir the raw materials added into the internal mixer, which not only prevents the raw materials from sticking to the inner wall of the mixing tank 1 but also stirs the raw materials to a certain extent. By stirring, the raw materials can be prevented from sticking to the wall, thereby improving the overall service life of the equipment. The support ring 6 and the fixing plate 7 provide support for the mixing tank 1.

[0025] Example 2

[0026] Reference Figure 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, a first gear 505 is fixedly connected to the surface of the feeding hopper 3, and a rotating column 506 is movably connected to the front end of the top of the mixing box 1 through a bearing. A second gear 507 is fixedly connected to the surface of the rotating column 506, and the first gear 505 meshes with the second gear 507.

[0028] The front and rear ends of the top of the rotating plate 2 are fixedly connected with connecting columns 508. The bottom of the connecting column 508 extends through the inner cavity of the mixing box 1 and is fixedly connected to the top of the upper fixing ring 501.

[0029] A motor 509 is installed on the top of the rotating column 506. The output shaft of the motor 509 is connected to the top of the rotating column 506. A fixing frame 510 is fixedly connected to the top of the motor 509. The bottom of the fixing frame 510 is fixedly connected to the top of the mixing box 1.

[0030] like Figure 2-4 As shown, the fixing frame 510 is used to fix the motor 509, the motor 509 is used to drive the rotating column 506 to rotate, the rotating column 506 then drives the second gear 507 to rotate. Since the first gear 505 and the second gear 507 mesh, under their cooperation, they can drive the rotating plate 2 and the feeding hopper 3 to rotate. When the rotating plate 2 rotates, it can cooperate with the connecting column 508 to drive the fixing ring 501, the connecting plate 502 and the scraper 503 to rotate. When the scraper 503 rotates, it can scrape off the raw materials adhering to the inner wall of the mixing box 1 to reduce the raw material residue. When the connecting plate 502 and the stirring blade 504 rotate, they can stir the raw materials.

[0031] Example 3

[0032] Reference Figure 1 and 2This is the third embodiment of the present invention, which is based on the first two embodiments.

[0033] In this embodiment, a support leg 8 is provided at the bottom of the fixing plate 7, and a cylinder 9 is fixedly connected to the inner cavity of the support leg 8. The output end of the cylinder 9 is fixedly connected to the bottom of the fixing plate 7.

[0034] The inner cavity of the mixing box 1 is movably connected to a rotating ring 10 via a bearing. Both sides of the lower fixed ring 501 are fixedly connected to fixed posts 11, and one end of the fixed post 11 is fixedly connected to the inner wall of the rotating ring 10.

[0035] like Figure 1 and 2 As shown, the support leg 8 is used to support the fixed plate 7, and in turn, the mixing box 1. The height of the mixing box 1 can be adjusted by starting the cylinder 9 so that the discharge hopper 4 can be better inserted into the feeding port of the internal mixer. The rotating ring 10 and the fixed column 11 cooperate to support the fixed ring 501.

[0036] In use, firstly, move the mixing box 1 to insert the discharge hopper 4 into the feeding port of the internal mixer. Then, start the cylinder 9 to make the discharge hopper 4 fit better with the feeding port of the internal mixer. Next, start the motor 509 and add raw materials into the mixing box 1 through the feeding hopper 3. When the motor 509 is running, it can drive the rotating column 506 to rotate. The rotating column 506 then drives the second gear 507 to rotate. Since the first gear 505 and the second gear 507 are meshed, they can drive the rotating plate 2 and the feeding hopper 3 to rotate. When the rotating plate 2 rotates, it can work with the connecting column 508 to drive the fixed ring 501, the connecting plate 502 and the scraper 503 to rotate. When the scraper 503 rotates, it can scrape off the raw materials adhering to the inner wall of the mixing box 1 to reduce raw material residue. When the connecting plate 502 and the stirring blade 504 rotate, they can stir the raw materials. The stirred raw materials are added into the internal mixer through the discharge hopper 4.
