A material lifting and conveying device for an open rubber mixing mill and its process

Abstract

The present invention discloses a material lifting and conveying device for an open rubber mixing mill and a process thereof, relating to the technical field of rubber mixing material transfer. The device comprises a diagonal support frame, a transmission roller, and a conveyor belt, wherein the highest and lowest points of the diagonal support frame are both rotatably connected to the transmission roller. The present invention provides a scraper blade and an in-position release assembly at the bottom of the conveyor belt, and a hot dip tank is provided at the bottom of the scraper blade. The residual rubber on the surface of the scraper blade is released into the interior of a capture net cylinder by the physical scraping of the in-position release assembly and the "thermal stripping" effect of hot water. This solves to a certain extent the problem that a certain amount of rubber remains on the surface of the conveyor belt of the material lifting and conveying device of the open rubber mixing mill after conveying the rubber. In order to improve the feed purity of the open rubber mixing mill, a scraper is often provided at the bottom of the conveyor belt to scrape off the residual rubber. However, after long-term use of the scraper blade, high-viscosity rubber easily adheres to and accumulates on the lower edge of the scraper blade. When the accumulated rubber hardens, it may cause wear on the belt surface.

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

[0003] In the prior art, after transporting the rubber, a certain amount of rubber will remain on the surface of the conveyor belt of the material lifting and conveying device of the open rubber mixer. In order to improve the purity of the feed 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 the scraper is used for a long time, the highly viscous rubber is easy to adhere to and accumulate on the lower edge of the scraper. When the accumulated rubber hardens, it may cause wear on the belt surface. Summary of the Invention

[0015] A material lifting and conveying process for an open rubber mixing mill comprises the following steps:

[0016] S1: The rubber material is conveyed normally and the 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 transmission roller to convey the low-altitude rubber material to the open rubber mixer feed port at a higher altitude. The scraper continuously scrapes the residual rubber material on the conveyor belt surface.

[0017] In step 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 hot dip tank. During this period, the capture net cylinder is controlled by the follower assembly to flip and sink into the hot liquid in the hot dip tank. The rubber accumulated on the outer wall of the scraper blade is soaked in hot water and falls into the capture net cylinder;

[0018] 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 net cylinder is controlled by the follower assembly to flip to an inverted state, releasing the rubber inside the capture net cylinder into the cavity of the hot dip box.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The present invention is provided with a scraper blade and an in-place release component at the bottom of the conveyor belt, a hot dip box is provided at the bottom of the scraper blade, and a partition plate is provided inside the hot dip box to divide the hot dip box into two independent chambers, one chamber is empty, and the other chamber is filled with a certain amount of hot water. The hot dip box is provided with a capture net cylinder rotating inside the hot water chamber, and a follower component is provided on the side of the capture net cylinder. The in-place release component can regularly drive the scraper blade to move into the hot water chamber, and utilize the physical scraping of the in-place release component and the "thermal peeling" effect of hot water to release the residual glue on the surface of the scraper blade into the capture net cylinder. To a certain extent, it solves the problem that the conveyor belt of the material lifting and conveying device of the open rubber mixing mill will retain a certain amount of glue on the surface after transporting the glue. In order to improve the feed purity of the open rubber mixing mill, a scraper is often provided at the bottom of the conveyor belt to scrape off the residual glue. However, after the scraper is used for a long time, the high-viscosity glue is easy to adhere to and accumulate on the lower edge of the scraper. After the accumulated glue hardens, it may cause wear to the belt surface.

[0021] 2. The present invention is provided with a scraper and an in-position release component at the bottom of the conveyor belt, a hot dip box is provided at the bottom of the scraper, a partition plate is provided inside the hot dip box to separate the hot dip box into two independent chambers, one chamber is empty, and the other chamber is filled with a certain amount of hot water, the hot dip box is provided with a capture net cylinder rotating inside the hot water chamber, and a follower component is provided on the side of the capture net cylinder. Before the scraper is controlled by the in-position release component to gradually enter the hot dip box, the in-position release component controls the follower component to extract and drive the capture net cylinder to salvage the rubber material floating on the surface of the hot dip box, and the follower component and the capture net cylinder are provided to form a linkage structure. Before the immersion tank enters the hot water chamber, the follower component is controlled to drive the capture net to salvage and clean the residual glue floating inside the hot water chamber, so as to avoid the scraper blade from coming into contact with the floating residual glue during the process of entering the hot water chamber, which may cause a decrease in cleaning effect or secondary pollution. This can effectively keep the water inside the hot water chamber clean, improve the softening and shedding efficiency of the residual glue on the surface of the scraper blade, and improve the overall cleaning quality. At the same time, the early execution of the salvage action reduces the possibility of long-term accumulation of glue in the hot water chamber, delays the problem of water deterioration, and extends the service life of the equipment. Through the pre-treatment mechanism of the linkage structure, the self-purification process of the hot water chamber is realized, and the frequency of manual maintenance is reduced.

[0045] The specific implementation steps and principles of the present invention are as follows:

[0046] refer to Figure 2 In the initial state, a partition plate 3 is provided inside the hot dip box 13 to divide the hot dip box 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 suspended above the cavity of the hot dip box 13. The scraper 22 is in contact with the bottom of the conveyor belt 4. The rubber material is conveyed normally and the scraper 22 continuously cleans the surface of the conveyor belt 4. The worker or conveying equipment puts the rubber material into the lower end of the conveyor belt 4. The conveyor belt 4 is driven by the lifting motor 6 and the transmission roller 5 to send the low-altitude rubber material to the high-altitude open rubber mixing mill feed port. The scraper 22 continuously scrapes off the residual rubber material on the surface of the conveyor belt 4. At this time, the driven column 29 is inside the bottom horizontal groove 283.

[0047] When the scraper 22 is self-cleaning, the controller 2 controls the lifting motor 6 to stop, and the common cylinder 141 to retract, and the conveyor belt 4 stops. Since the pitch circle diameter of the flip gear 33 is smaller than the pitch circle diameter of the transfer gear 24, the in-place release component controls the scraper 22 to gradually rotate to the top of the hot dip box 13. Specifically, the transfer gear 28 and the transfer gear 24 drive the scraper 22 to rotate, and the driven column 29 moves along the bottom transverse groove 283, the inclined groove 282, and the top transverse groove 281, and quickly drives the capture net cylinder 34 through the vertical gear rod 30 and the flip gear 33 to flip and sink into the hot liquid in the inner cavity of the hot dip box 13 under the control of the follower component. During this period, the lifting column 19 moves along the outer wall of the fixed cam 26, forcing the glue pushing frame 21 to move along the outer wall of the scraper 22. The glue accumulated on the outer wall of the scraper 22 is soaked in hot water and falls off into the inside of the capture net cylinder 34.

[0048] When the scraper blade 22 is reset and resumes continuous cleaning of the surface of the conveyor belt 4, the in-place release assembly controls the scraper blade 22 through the above-mentioned components to gradually rotate and return to the bottom of the conveyor belt 4. During this period, the capture net cylinder 34 is controlled by the follow-up assembly using the above-mentioned corresponding components to flip to an inverted state, releasing the rubber material inside the capture net cylinder 34 into the cavity of the hot dip box 13.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.

A material lifting and conveying process for an open rubber mixing mill, used for a material lifting and conveying device for an open rubber mixing mill according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1: The rubber material is conveyed normally and the 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 transmission roller to convey the low-altitude rubber material to the open rubber mixer feed port at a higher altitude. The scraper continuously scrapes the residual rubber material on the conveyor belt surface. In step 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 hot dip tank. During this period, the capture net cylinder is controlled by the follower assembly to flip and sink into the hot liquid in the hot dip tank. The rubber accumulated on the outer wall of the scraper blade is soaked in hot water and falls 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 net cylinder is controlled by the follower assembly to flip to an inverted state, releasing the rubber inside the capture net cylinder into the cavity of the hot dip box.
