DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-2 As shown, a waste processing device of an open rubber mixing machine includes a mounting frame 1, a connecting frame 3 is fixedly installed on the upper surface of the mounting frame 1, an electric push rod 4 is fixedly installed on the upper surface of the connecting frame 3, a scraper assembly 5 is fixedly installed between two groups of piston rods of the electric push rod 4, a reduction motor 2 is fixedly installed on the upper surface of the mounting frame 1, a rubber mixing wheel 203 is rotatably installed between the two groups of connecting frames 3, a first gear plate 201 and a second gear plate 202 are fixedly installed at one end of the two groups of rubber mixing wheels 203, the first gear plate 201 is meshed with the second gear plate 202, a reduction motor 2 is fixedly installed at one end of the first gear plate 201, and the reduction motor 2 is fixedly installed on the upper surface of the mounting frame 1.

[0022] Through the design of the reduction motor 2, the first gear plate 201, the second gear plate 202, the rubber mixing wheel 203, the electric push rod 4 and the scraper assembly 5, when refining rubber, the staff can start the reduction motor 2 to drive the first gear plate 201 to mesh with the second gear plate 202 to rotate, thereby driving the rubber mixing wheel 203 at one end of the first gear plate 201 and the second gear plate 202 to rotate relatively, and then the staff can pour the raw materials between the two groups of rubber mixing wheels 203, so that under the rotation of the rubber mixing wheels 203, the raw materials are repeatedly folded, sheared and stretched between the rubber mixing wheels 203, thereby achieving material mixing. In this process, various components in the raw materials are evenly distributed, achieving the expected rubber mixing effect;

[0023] The refined rubber can then be cut from the rubber mixing wheel 203. If there is still some rubber mixing residue stuck to the rubber mixing wheel 203, the staff can start the electric push rod 4 to push the scraper assembly 5 to touch the surface of the two sets of rubber mixing wheels 203. As the rubber mixing wheel 203 rotates, the scraper assembly 5 can scrape the rubber mixing residue on the rubber mixing wheel 203 and convey it to the carrier plate 502 along the conveyor belt 503 for centralized collection, so as to achieve the effect of quickly cleaning the rubber mixing wheel 203, thereby eliminating the need for the staff to manually and spend a long time on cleaning the rubber mixing residue, thereby improving the startup efficiency during rubber refining, and quickly cleaning the rubber mixing residue can ensure that the equipment is always in the best condition, thereby improving production efficiency, and also avoiding the mixing of the rubber mixing residue with the new batch of rubber, resulting in the product not meeting the quality standards.

[0024] like Figure 3-Figure 4 As shown, the scraper assembly 5 includes an arc-shaped scraper 501 , and mounting plates 504 are fixedly mounted on both ends of the arc-shaped scraper 501 . The arc-shaped scraper 501 is fixedly mounted between the piston rods of the two groups of electric push rods 4 through the mounting plates 504 .

[0025] The arc-shaped scraper 501 can contact the upper ends of the outer surfaces of the two sets of rubber mixing wheels 203 .

[0026] Both ends of the arc-shaped scraper 501 are provided with mounting openings 507 , and a conveyor belt 503 is installed in the mounting openings 507 , and the conveyor belt 503 can cover the mounting openings 507 .

[0027] The conveyor belt 503 is a Teflon conveyor belt 503 .

[0028] Two sets of motors 506 are fixedly mounted on one end of the mounting plate 504 , and the output shafts of the motors 506 are fixedly connected to the transmission columns in the conveyor belt 503 .

[0029] A carrying plate 502 is fixedly mounted on one end of the arc scraper 501 , and there is a discharge distance between the carrying plate 502 and the conveyor belt 503 . A guide scraper 505 is fixedly mounted on the upper surface of the carrying plate 502 , and the guide scraper 505 contacts the surface of the conveyor belt 503 .

[0030] The guide scraper 505 is made of polytetrafluoroethylene material.

[0031] Through the design of the arc scraper 501, the carrying plate 502, the conveyor belt 503, the motor 506 and the guide scraper 505, when cleaning the rubber mixing residue on the rubber mixing wheel 203, the staff can start the electric push rod 4 to push the arc scraper 501 to touch the surface of the two groups of rubber mixing wheels 203, and as the rubber mixing wheels 203 rotate, the arc scraper 501 can scrape the rubber mixing residue on the rubber mixing wheel 203 and attach it to the surface of the conveyor belt 503 and be driven by the motor 506 to one end of the guide scraper 505, and the guide scraper 505 can scrape the rubber mixing residue on the surface of the conveyor belt 503 and push it to the carrying plate 502 along the arc surface of the guide scraper 505 for centralized collection operation, that is, the purpose of cleaning the rubber mixing residue on the rubber mixing wheel 203 is completed, thereby avoiding the mixing of the rubber mixing residue with the new batch of rubber, resulting in the product not meeting the quality standard.

[0032] The conveyor belt 503 and the guide scraper 505 are made of Teflon and polytetrafluoroethylene respectively. Teflon is a synthetic resin with excellent heat resistance, corrosion resistance and non-stickiness. The conveyor belt 503 made of Teflon has a smooth surface and low adhesion to rubber raw materials. Therefore, when the processed and warm rubber refining residue is conveyed, the rubber refining residue will not adhere to the conveyor belt 503. In addition, the scraping of the guide scraper 505 can make the rubber refining residue fall off the conveyor belt 503 easily.

[0033] Polytetrafluoroethylene is also a very famous anti-stick material with extremely low surface energy and excellent chemical resistance, and its adhesion to rubber is very low. Therefore, in the process of scraping the rubber mixing residue, the adhesion of the rubber mixing residue can be avoided, and only the rubber mixing residue can be guided.

[0034] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when refining rubber, the staff can start the reduction motor 2 to drive the first gear plate 201 to mesh with the second gear plate 202 to rotate, thereby driving the rubber mixing wheel 203 at one end of the first gear plate 201 and the second gear plate 202 to rotate relatively, and then the staff can pour the raw materials between the two groups of rubber mixing wheels 203, so that under the rotation of the rubber mixing wheels 203, the raw materials are repeatedly folded, sheared and stretched between the rubber mixing wheels 203, thereby achieving material mixing. In this process, various components in the raw materials are evenly distributed to achieve the expected rubber mixing effect;

[0035] Then the refined rubber can be cut from the rubber mixing wheel 203. If there is still some rubber mixing residue stuck to the rubber mixing wheel 203, the staff can start the electric push rod 4 to push the arc scraper 501 to touch the surface of the two groups of rubber mixing wheels 203. As the rubber mixing wheel 203 rotates, the arc scraper 501 can scrape off the rubber mixing residue on the rubber mixing wheel 203 and attach it to the surface of the conveyor belt 503 and be driven by the motor 506 to one end of the guide scraper 505. The guide scraper 505 can scrape off the rubber mixing residue on the surface of the conveyor belt 503 and push it to the carrier plate 502 along the arc surface of the guide scraper 505 for centralized collection, thereby completing the purpose of cleaning the rubber mixing residue on the rubber mixing wheel 203.

[0036] In summary: it has the effect of cleaning the rubber mixing wheel 203, eliminating the need for staff to manually and time-consumingly clean the rubber mixing residues, thereby increasing the restart efficiency during rubber refining, and avoiding the mixing of rubber mixing residues with new batches of rubber, resulting in products that do not meet quality standards.
