[0002] An open rubber mixer is a device used for the preliminary mixing and plasticizing of rubber. It consists of two horizontally placed rollers, which evenly mix raw materials through shearing, extrusion, etc. To improve production efficiency and achieve continuous operation, a belt conveyor is often used in combination to transport materials such as rubber or additives from a lower position to the feeding port of the rubber mixer. The belt conveyor can not only reduce the manual handling intensity but also achieve automatic feeding, improving the safety and stability of the entire rubber mixing process.

[0003] In the prior art, after the conveyor belt of the material lifting and conveying device of an open rubber mixer transports rubber material, a certain amount of rubber material will remain on the surface. To improve the feeding purity of the open rubber mixer, a scraper is often provided at the bottom of the conveyor belt to scrape off the residual rubber. However, after long-term use, highly viscous rubber material is likely to adhere to and accumulate on the lower edge of the scraper, and the accumulated rubber may cause wear to the surface of the belt after hardening.

[0014] A material lifting and conveying process for an open rubber mixer comprises the following steps: S1. Normal conveying of the rubber compound and continuous cleaning of the surface of the conveying belt by the scraping knife. Workers or conveying equipment put the rubber compound into the lower end of the conveying belt. The conveying belt is driven by the lifting motor and the transmission roller to send the rubber compound at a low altitude into the feeding port of the open rubber mixer at a high altitude, and the scraping knife continuously scrapes the residual rubber compound on the surface of the conveying belt. S2. Self-cleaning of the scraping knife. The conveying belt stops rotating, and the in-place release assembly controls the scraping knife to gradually rotate to the top of the immersion tank. During this period, the capture semi-cylinder is controlled by the follower assembly to turn over and sink into the hot liquid inside the inner cavity of the hot dipping tank, and the rubber compound accumulated on the outer wall of the scraping knife falls off into the capture net cylinder under the soaking of hot water. S3. Reset of the scraping knife and restoration of continuous cleaning of the surface of the conveying belt by the scraping knife. The in-place release assembly controls the scraping knife to gradually rotate back to the bottom of the conveying belt. During this period, the capture semi-cylinder is controlled by the follower assembly to turn over to an inverted state, and the rubber compound inside the capture semi-cylinder is released into the cavity of the hot dipping tank.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention is provided with a scraping knife and a positioning and releasing component at the bottom of the conveying belt. A hot dipping tank is arranged at the bottom of the scraping knife. A partition plate is arranged inside the hot dipping tank to divide the hot dipping tank into two independent chambers. One chamber is empty, and the other chamber is filled with a certain amount of hot water. A capture net cylinder is rotatably arranged inside the hot dipping tank in the hot water chamber. A follower component is arranged on the side of the capture net cylinder. The positioning and releasing component can drive the scraping knife to move into the hot water chamber at regular intervals. By using the physical scraping of the positioning and releasing component and the "thermal stripping" effect of the hot water, the residual glue on the surface of the scraping knife is released into the capture net cylinder, which to a certain extent solves the problem that after the conveying belt of the material lifting and conveying device of the open mill transports the rubber material, a certain amount of rubber material will remain on the surface. In order to improve the feeding purity of the open mill, a scraping knife is often arranged at the bottom of the conveying belt to scrape off the residual glue. However, after long-term use of the scraping knife, the highly viscous rubber material is easily adhered and accumulated on the lower edge of the scraping knife, and the accumulated glue may cause wear to the surface of the belt after hardening.

[0016] 2. The present invention is provided with a scraping knife and a positioning and releasing component at the bottom of the conveying belt. A hot dipping tank is arranged at the bottom of the scraping knife. A partition plate is arranged inside the hot dipping tank to divide the hot dipping tank into two independent chambers. One chamber is empty, and the other chamber is filled with a certain amount of hot water. A capture net cylinder is rotatably arranged inside the hot dipping tank in the hot water chamber. A follower component is arranged on the side of the capture net cylinder. Before the scraping knife is gradually controlled by the positioning and releasing component and enters the hot dipping tank, the positioning and releasing component controls the follower component to drive the capture net cylinder to fish away the rubber material floating on the surface of the hot dipping tank. A linkage structure is formed by setting the follower component and the capture net cylinder. Before the scraping knife enters the hot water chamber of the hot dipping tank, the follower component is controlled to drive the capture net cylinder to fish and clean the residual glue floating inside the hot water chamber first, so as to avoid the scraping knife contacting the floating residual glue during the process of entering the hot water chamber, resulting in a decline in the cleaning effect or secondary pollution. It can effectively keep the water body inside the hot water chamber clean, improve the softening and falling-off efficiency of the residual glue on the surface of the scraping knife, and improve the overall cleaning quality. At the same time, the early execution of the fishing action reduces the possibility of long-term accumulation of rubber material in the hot water chamber, delays the problem of water body deterioration, extends the service life of the equipment, and realizes the self-purification process of the hot water chamber through the pre-treatment mechanism of the linkage structure, reducing the frequency of manual maintenance.

[0040] The specific implementation steps and principles of the present invention are as follows: Reference Figure 2 As shown in the figure, in the initial state, a partition plate 3 is arranged inside the hot dipping tank 13 to divide the hot dipping tank into two independent chambers. One chamber is empty, and the other chamber is filled with a certain amount of hot water. The capture net cylinder 34 is in an inverted state and hangs above the cavity of the hot dipping tank 13. The rubber scraping knife 22 is in a state of being attached to the bottom of the conveying belt 4. The rubber material is normally conveyed, and the rubber scraping knife 22 continuously cleans the surface of the conveying belt 4. Workers or conveying equipment put the rubber material into the low end of the conveying belt 4. The conveying belt 4 is driven by a lifting motor 6 and a transmission roller 5 to send the rubber material at a low altitude into the feeding port of the open mill at a high altitude. The rubber scraping knife 22 continuously scrapes the residual rubber material on the surface of the conveying belt 4. At this time, the driven column 29 is inside the bottom horizontal groove 283.

[0041] When the rubber scraping knife 22 performs self-cleaning, the controller 2 controls the lifting motor 6 to stop rotating, and the common cylinder 141 retracts. The conveying belt 4 stops rotating. Since the pitch circle diameter of the flipping gear 33 is smaller than that of the transfer gear 24, before the rubber scraping knife 22 gradually rotates to the top of the immersion tank 13, specifically, the transfer rack 28 and the transfer gear 24 drive the rubber scraping knife 22 to rotate. The driven column 29 moves along the bottom horizontal groove 283, the inclined groove 282, and the top horizontal groove 281, and quickly drives the capture net cylinder 34 to be flipped and sunk into the hot liquid inside the cavity of the hot dipping tank 13 under the control of the follower assembly through the vertical rack 30 and the flipping gear 33. During this period, the lifting column 19 moves along the outer wall of the fixed cam 26, forcing the rubber pushing frame 21 to move along the outer wall of the rubber scraping knife 22. The rubber material accumulated on the outer wall of the rubber scraping knife 22 falls off into the capture net cylinder 34 under the soaking of hot water.

[0042] When the rubber scraping knife 22 resets and the rubber scraping knife 22 resumes continuous cleaning of the surface of the conveying belt 4, the in-place release assembly controls the rubber scraping knife 22 to gradually rotate back to the bottom of the conveying belt 4 through the above-mentioned components. During this period, the capture net cylinder 34 is controlled by the follower assembly to be flipped to the inverted state by using the above-mentioned corresponding components, and the rubber material inside the capture net cylinder 34 is released into the cavity of the hot dipping tank 13.

[0043] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.

10. A material lifting and conveying process for an open rubber mixer, used for a material lifting and conveying device for an open rubber mixer as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1, the rubber material is conveyed normally and the rubber scraper continuously cleans the surface of the conveyor belt. Workers or conveying equipment put the rubber material into the lower end of the conveyor belt. The conveyor belt is driven by the lifting motor and the transmission roller to send the low-altitude rubber material to the high-altitude open rubber mixer feed port. The rubber scraper continuously scrapes the residual rubber material on the surface of the conveyor belt. S2, the scraper blade self-cleans, the conveyor belt stops, and the release assembly controls the scraper blade to gradually rotate to the top of the immersion box. During this period, the capture half cylinder is controlled by the follower assembly to flip and sink into the hot liquid in the hot immersion box. The rubber accumulated on the outer wall of the scraper blade is soaked in hot water and falls off into the capture net cylinder; S3, the scraper blade is reset and restored to continuously clean the surface of the conveyor belt. The release assembly in place controls the scraper blade to gradually rotate and return to the bottom of the conveyor belt. During this period, the capture half-cylinder is controlled by the follow-up assembly to flip to an inverted state, releasing the rubber inside the capture half-cylinder into the cavity of the hot dip box.
