Description

Technical Field

[0001] This invention relates to the field of rubber roller manufacturing and processing technology, specifically a method for manufacturing and processing a high wear-resistant rubber roller. Background Technology

[0002] High-abrasion-resistant rubber rollers are widely used components in industrial production. They are made by wrapping a metal mandrel with a rubber material (referred to as rubber compound) that has high abrasion resistance. These rollers maintain good abrasion resistance, corrosion resistance, and mechanical properties in various harsh working environments. The abrasion resistance of high-abrasion-resistant rubber rollers mainly depends on the quality of the rubber compound. Since the formation of the rubber compound typically involves two processes: internal mixing and open mixing, the initial internal mixing is fundamental to ensuring the quality of the rubber compound. Ensuring the effective mixing of the raw materials and compounding agents during internal mixing is a crucial step.

[0003] The equipment used for internal mixing of rubber raw materials is usually an internal mixer. This type of internal mixer uses two internal mixing rollers rotating in opposite directions for the main internal mixing process. At the same time, in order to ensure the closedness of the internal mixing process, a cylinder located at the top usually drives an upper sealing block to work in conjunction with the part inside the internal mixer located below the position of the internal mixing rollers to form a closed space for internal mixing of rubber raw materials.

[0004] While the aforementioned equipment for internal mixing of rubber raw materials can efficiently mix rubber raw materials and compounding agents using internal mixing rollers, the presence of powdery components in these materials necessitates precise control of the ratio of raw materials and compounding agents during raw material preparation to ensure the required abrasion and corrosion resistance of the final rubber compound. However, the powdery components tend to adhere to the inner sidewalls of the internal mixer during feeding and cannot be incorporated into the mixing process, resulting in poor abrasion and corrosion resistance in the final compound. Furthermore, during the internal mixing process, the raw materials and compounding agents are prone to agglomeration, and some compounding agents cannot quickly and evenly diffuse into the rubber raw materials, further affecting the abrasion resistance of the final compound. The aforementioned internal mixing equipment can only address this issue through prolonged mixing, which in turn reduces mixing efficiency. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a production and processing method for a high wear-resistant rubber roller, which specifically includes the following steps: S1, processing of the rubber roller mandrel: firstly, the mandrel blank is initially formed by forging or rolling, then the initially formed mandrel blank is rough processed by turning the round and end face, and then the surface of the mandrel is finely processed by grinding.

[0006] S2. Preparation of raw materials for rubber compound: Prepare the ingredients for the rubber compound in sequence, and use precise measurement to ensure that the proportions of the various ingredients in the rubber compound meet the requirements.

[0007] S3. Rubber compound mixing: The prepared rubber compound ingredients are added to the rubber compound mixing equipment in sequence, and the mixing rollers are driven by the power unit to perform the mixing operation. After the mixing is completed, the rubber compound is subjected to open milling operation.

[0008] S4. Coating: The rubber compound, after being processed, is coated onto the rubber roller mandrel by extrusion coating, ensuring that the rubber compound and the rubber roller mandrel are in close contact.

[0009] S5. Vulcanization treatment: The rubber rollers with rubber coating are vulcanized in a vulcanizing tank until the wear resistance and strength of the rubber rollers meet the requirements for use.

[0010] The production process of high-wear-resistant rubber rollers using steps S1-S5 specifically involves a rubber compound mixing device, including an installation platform. A lower sealing box is connected to the top of the installation platform via a support mechanism. The lower sealing box contains mixing rollers driven by a power assembly mounted on the support mechanism, arranged both front and rear. A pressure mixing mechanism is symmetrically arranged front and rear within the lower sealing box. An upper sealing box is mounted on the top of the installation platform via symmetrically mounted L-shaped support frames. An inlet is located on the rear side of the upper sealing box. Both the upper and lower sealing boxes contain a common sealing mechanism. The upper and lower sealing boxes can be connected and interlocked. All joints of the sealing boxes are arc-shaped; the pressure mixing mechanism can avoid and uniformly mix the rubber material after being pressed by a sufficient amount of raw material; the sealing mechanism includes a U-shaped frame fixed to the top of the upper sealing box, a multi-stage electric push rod fixed to the bottom of the horizontal section of the U-shaped frame, a limit plate fixed to the pushing end of the multi-stage electric push rod, a sealing block connected to the limit plate through a reset structure, the bottom of the sealing block is M-shaped, and a rotating shovel plate is symmetrically hinged to the bottom of the sealing block at the front and rear positions of two arc-shaped recesses; the inner wall of the lower sealing box is symmetrically provided with trajectory components for cooperating with the rotating shovel plate on the front side.

[0011] Furthermore, the support mechanism includes vertical plates symmetrically fixed to the top of the installation platform. A through column is rotatably installed on the left vertical plate, and a hollow column is fixed to the right end of the through column. The hollow column is fixedly connected to the lower sealing box. A rotating column is fixed to the right side of the lower sealing box. A mixing roller on the front side is rotatably installed between the hollow column and the rotating column. The rotating column is rotatably connected to the right vertical plate, and the two are connected together by a rotating structure for driving the rotating column and the lower sealing box to rotate.

[0012] Furthermore, the rotating structure includes a cylinder fixed to the front side of the vertical plate, and a connecting plate fixed to the pushing end of the cylinder; an inclined extension rod is fixed to the side of the rotating column, and a connecting rod is hinged between the end of the extension rod away from the rotating column and the connecting plate.

[0013] Furthermore, the power assembly includes a No. 1 motor mounted on the left end of the through-column via a motor box, the output end of the No. 1 motor passing through the through-column and connected to the front mixing roller; limit posts are symmetrically installed on the left and right sides of the lower sealing box, corresponding to the positions of the rear mixing roller, and the limit posts are rotatably connected to the rear mixing roller; a rear extension plate is fixed to the side of the rotating column, and a No. 2 motor is mounted on the left side of the rear extension plate via a motor mount, the output end of the No. 2 motor passing through the limit post and connected to the rear mixing roller.

[0014] Furthermore, the reset structure includes vertical columns symmetrically fixed to the top of the closed block, the vertical columns sliding through the limiting plate, and a circular plate fixed to the top of each vertical column, with a vertical spring connecting the circular plate and the limiting plate.

[0015] Furthermore, the sealing block is symmetrically fixed with inclined scrapers at the front and back. The inclined scrapers are located closer to the inner wall of the upper sealing box than the rotating shovel. Each rotating shovel has an inner groove symmetrically arranged on the left and right. The inner groove is connected by an inner spring to a matching rod that is symmetrical on the left and right and cooperates with the trajectory component. A torsion spring is provided at the hinge position of the rotating shovel.

[0016] Furthermore, the trajectory component includes a square through slot opened on the lower sealing box, a sealing plate fixed on the outer wall of the lower sealing box at the position corresponding to the square through slot, and a guide rail provided inside the sealing plate. The guide rail, in conjunction with the positioning rod, drives the rotating shovel to reciprocate.

[0017] Furthermore, a protrusion is provided in the middle position inside the lower sealing box and below the mixing roller; the pressure mixing mechanism includes an arc-shaped groove opened inside the lower sealing box, a pressure block is slidably connected in the arc-shaped groove, and clearance grooves are symmetrically arranged in front and behind the arc-shaped groove. Inner extension plates are fixed on the front and back sides of the pressure block and at positions corresponding to the clearance grooves. Multiple return springs are connected between the inner extension plates and the bottom of the clearance grooves. Multiple rotating components are evenly arranged in the pressure block, and a transmission component for driving the rotating components is connected between the pressure block and the arc-shaped groove.

[0018] Furthermore, the rotating component includes multiple sets of horizontally arranged rotating rods rotatably installed at the bottom of the arc-shaped groove. Each rotating rod slides through the pressure block, and rotating plates are symmetrically arranged on the sides of the rotating rods. A receiving groove for accommodating the rotating plates is provided inside the pressure block.

[0019] Furthermore, the transmission component includes a connecting column rotatably mounted at the bottom of the arc-shaped groove and corresponding to each set of rotating rods. A transmission belt is connected between the connecting column and each set of rotating rods. A reset torsion spring is connected between the connecting column and the arc-shaped groove. A positioning block is connected to the top of the connecting column via a disc. A trapezoidal block is fixed to the bottom of the pressure block and to each positioning block.

[0020] The beneficial effects of this invention are as follows: First, this invention uses a slanted scraper in conjunction with a rotating shovel to thoroughly remove the rubber raw materials and compounding agents adhering to the front and rear side walls of the upper and lower sealing boxes. Furthermore, the trajectory component on the lower sealing box enhances the removal effect in areas with a high concentration of adhering rubber raw materials and compounding agents, and allows the rotating shovel to rotate frequently, thus preventing the removed rubber raw materials and compounding agents from adhering to the rotating shovel and causing insufficient amounts of rubber raw materials or compounding agents during the mixing process. Additionally, the method of mixing the rubber raw materials and compounding agents using a rotating plate that is converging from the receiving tank prevents the rubber raw materials and compounding agents from adhering to the rotating plate or rotating rod during mixing, further ensuring that the amounts of rubber raw materials and compounding agents during the mixing process conform to the preset ratio.

[0021] Second, the present invention employs a pressure mixing mechanism that avoids the pressure block after it is subjected to sufficient rubber raw material. The movement of the pressure block after being pressed is transmitted through a transmission component and drives the rotating rod and rotating plate to rotate continuously. This allows the rotating rod and rotating plate to uniformly mix the rubber raw material and compounding agents in this part. In combination with the internal mixing roller, this improves the diffusion efficiency of the compounding agents in the rubber raw material, thereby ensuring that the compounding agents fully react with the rubber raw material and improving the wear resistance of the rubber compound after internal mixing.

[0022] Third, this invention forms a closed space for the internal mixing of rubber raw materials and compounding agents by means of a closed block connected to a limiting plate via a reset structure, along with a pressure block and a lower sealing box. This ensures the mixing effect and sealing of the rubber raw materials and compounding agents. At the same time, the elastic expansion and contraction effect of the reset structure allows the closed block to quickly avoid easily clogged agglomerated rubber raw materials and compounding agents. Similarly, the pressure block can also avoid easily clogged agglomerated rubber raw materials and compounding agents, thereby reducing the risk of a large amount of rubber raw materials and compounding agents agglomerating and causing the mixing roller to be unable to rotate and mix them, while improving the mixing efficiency.

[0035] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0036] See Figure 2 , Figure 3 and Figure 4 A method for producing high wear-resistant rubber rollers involves a rubber compound mixing equipment, including an installation platform 1. A lower sealing box 3 is connected to the top of the installation platform 1 via a support mechanism 2. The lower sealing box 3 has mixing rollers 32 driven by a power component 31 mounted on the support mechanism 2, both at the front and back. A pressure mixing mechanism 4 is symmetrically arranged at the front and back of the lower sealing box 3. An upper sealing box 5 is installed on the top of the installation platform 1 via L-shaped support frames 11 symmetrically installed on the left and right. An inlet 51 is provided on the rear side of the upper sealing box 5. A sealing mechanism 6 is provided in both the upper sealing box 5 and the lower sealing box 3. The upper sealing box 5 and the lower sealing box 3 can be connected to each other, and the splicing position of the upper sealing box 5 and the lower sealing box 3 is arc-shaped.

[0037] This invention uses a mixing roller 32 to mix the rubber compound, while a sealing mechanism 6 fully seals the rubber compound during the mixing process. This, in conjunction with the mixing roller 32, effectively mixes and blends the rubber compound. Furthermore, a pressure mixing mechanism 4 is used to improve the mixing effect of the mixing roller 32 on the rubber compound and accelerate the mixing efficiency of the rubber compound raw materials and compounding agents. It also ensures that the compounding agents in the rubber compound raw materials are fully dispersed, thereby ensuring the wear resistance and quality of the rubber compound after mixing.

[0038] Specifically, firstly, the pre-prepared rubber raw materials and various compounding agents are sequentially added to the space formed by the upper sealing box 5 and the lower sealing box 3 through the feed inlet 51. Then, the sealing mechanism 6 is controlled to cooperate with the lower sealing box 3 to complete the sealing of the rubber raw materials and compounding agents. After sealing, the power component 31 drives the two internal mixing rollers 32 to rotate in opposite directions, so that the rubber raw materials and compounding agents are fully mixed and reacted through the internal mixing rollers 32. During the reaction, the pressure mixing mechanism 4 is subjected to a large amount of agglomerated rubber raw materials and compounding agents, so as to avoid the agglomerated rubber raw materials and compounding agents and further mix them, thereby ensuring the mixing effect of the compounding agents. After all the rubber raw materials and compounding agents are internally mixed, the sealing mechanism 6 is controlled to return to its original position. Then, the support mechanism 2 drives the lower sealing box 3 to rotate and cooperate with the internal mixing rollers 32 to discharge the internally mixed rubber compound.

[0039] It should be noted that the mixing roller 32 is provided with spiral protrusions distributed on the left and right sides, and the two spiral protrusions are centrally symmetrical. This type of mixing roller 32 is quite common in actual equipment for mixing rubber materials, and it is not the main inventive point of this invention, so it will not be described in detail.

[0040] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 The sealing mechanism 6 includes a U-shaped frame 61 fixed to the top of the upper sealing box 5. A multi-stage electric push rod 611 is fixed to the bottom of the horizontal section of the U-shaped frame 61. A limit plate 612 is fixed to the pushing end of the multi-stage electric push rod 611. A sealing block 613 is connected to the limit plate 612 through a reset structure. The bottom of the sealing block 613 is M-shaped. A rotating shovel plate 614 is symmetrically hinged to the bottom of the sealing block 613 and located at the front and rear positions of two arc-shaped recesses. Track components 62 for cooperating with the rotating shovel plate 614 on the left and right sides are symmetrically arranged on the inner wall of the lower sealing box 3. The reset structure includes vertical columns 630 symmetrically fixed to the top of the sealing block 613. The vertical columns 630 slide through the limit plate 612. A circular plate 631 is fixed to the top of each vertical column 630. A vertical spring is connected between the circular plate 631 and the limit plate 612.

[0041] The sealing mechanism 6 can not only perform internal mixing of rubber raw materials through the sealing block 613 and the internal mixing roller 32, but also scrape off the rubber raw materials or powdered compounding agents adhering to the front and rear side walls of the upper sealing box 5 and the lower sealing box 3 by rotating the shovel plate 614 and cooperating with the trajectory component 62. This avoids the situation where the amount of rubber raw materials or compounding agents is insufficient during the internal mixing process due to the rubber raw materials or powdered compounding agents adhering to the front and rear side walls of the upper sealing box 5 and the lower sealing box 3. Furthermore, since the inlet 51 is located on the rear side of the upper sealing box 5, the trajectory component 62 located on the front side can be used to specifically scrape off the areas where more rubber raw materials or compounding agents are adhered.

[0042] Specifically, the pre-prepared rubber raw materials and various compounding agents are first added sequentially to the space formed by the upper sealing box 5 and the lower sealing box 3 through the feed port 51. Then, the multi-stage electric push rod 611 is controlled to drive the limiting plate 612 and the sealing block 613 to move downward, thereby cooperating with the lower sealing box 3 to complete the sealing of the rubber compound mixing area. At the same time, a reset structure is connected between the limiting plate 612 and the sealing block 613. Through the reset structure, the sealing block 613 can avoid the agglomerated rubber raw materials and compounding agents, thereby ensuring the progress of the mixing process. As the sealing block 613 moves downward, the rotating shovels 614 on the front and rear sides will simultaneously scrape off the rubber raw materials and compounding agents from the side walls of the upper sealing box 5 and the lower sealing box 3, and return the scraped rubber raw materials and compounding agents to the position of the mixing roller 32, thereby ensuring that the amount of rubber raw materials and compounding agents in the mixing process meets the preset ratio.

[0043] See Figures 4-6The sealing block 613 is symmetrically fixed with inclined scrapers 615 at the front and back. The inclined scrapers 615 are located closer to the inner wall of the upper sealing box 5 than the rotating shovel 614. Each rotating shovel 614 has an inner groove symmetrically arranged on the left and right. The inner groove is connected by an inner spring to a positioning rod 616 that is symmetrical on the left and right and cooperates with the track component 62. A torsion spring is provided at the hinge position of the rotating shovel 614. The track component 62 includes a square through slot 621 opened on the lower sealing box 3. A sealing plate 622 is fixed on the outer wall of the lower sealing box 3 at the position corresponding to the square through slot 621. A guide rail 623 is provided in the sealing plate 622. The rotating shovel 614 is driven to reciprocate through the guide rail 623 and the positioning rod 616. The guide rail 623 is composed of multiple unconnected vertical guide parts and bent guide parts that are connected to the adjacent vertical guide parts.

[0044] The inclined scraper 615, in conjunction with the rotating shovel 614, thoroughly removes the rubber raw materials and compounding agents adhering to the front and rear side walls of the upper sealing box 5 and the lower sealing box 3. Furthermore, the trajectory component 62 set on the lower sealing box 3 enhances the removal effect in areas with a large amount of adhering rubber raw materials and compounding agents. The frequent rotation of the rotating shovel 614 also prevents the removed rubber raw materials and compounding agents from adhering to the rotating shovel 614, thus avoiding insufficient amounts of rubber raw materials or compounding agents during the mixing process.

[0045] Specifically, during the process of controlling the multi-stage electric push rod 611 to drive the limit plate 612 and the sealing block 613 to move downward, the rotating scraper 614 will adhere to the front and rear side walls of the upper sealing box 5 and the lower sealing box 3 due to the action of the torsion spring. This, together with the inclined scraper 615, will completely remove the rubber raw materials and compounding agents adhering to the front and rear side walls of the upper sealing box 5 and the lower sealing box 3, and cause the removed rubber raw materials and compounding agents to fall into the area where the mixing roller 32 is located.

[0046] When the rotating shovel 614 on the front side rotates to the position of the track member 62, the positioning rods 616 on both sides will extend to the left and right respectively due to the action of the inner spring, thereby moving to abut against the closing plate 622 and extending into the guide rail 623. Due to the guiding effect of the guide rail 623 on the positioning rods 616, the rotating shovel 614 rotates away from the front side wall of the lower sealing box 3. During the rotation of the rotating shovel 614, the inclined scraper 615 will continuously scrape off the part of the rubber material that the rotating shovel 614 has not scraped off, thereby making the scraped part of the rubber material... The removed rubber raw materials and compounding agents are scattered towards the middle area of ​​the mixing roller 32 by the swishing action of the rotating shovel 614, thus avoiding the situation where rubber raw materials and compounding agents adhere to the front rotating shovel 614 during the shoveling process. Since there are fewer rubber raw materials adhering to the rear side walls of the upper sealing box 5 and the lower sealing box 3, the rear rotating shovel 614 will not have the situation of rubber raw materials and compounding agents adhering to it. By repeatedly swishing the removed rubber raw materials and compounding agents, it is ensured that the amount of rubber raw materials and compounding agents during the rubber mixing process meets the preset ratio.

[0047] See Figure 2 , Figure 3 and Figure 4 The support mechanism 2 includes vertical plates 21 symmetrically fixed to the top of the mounting platform 1. A through column 211 is rotatably mounted on the left vertical plate 21. A hollow column 212 is fixed to the right end of the through column 211. The hollow column 212 is fixedly connected to the lower sealing box 3. A rotating column 213 is fixed to the right side of the lower sealing box 3. A mixing roller 32 on the front side is rotatably mounted between the hollow column 212 and the rotating column 213. The rotating column 213 is rotatably connected to the right vertical plate 21, and the two are connected together by a rotating structure for driving the rotating column 213 and the lower sealing box 3 to rotate. The rotating structure includes a cylinder 220 fixed to the front side of the vertical plate 21. A connecting plate 221 is fixed to the pushing end of the cylinder 220. An inclined extension rod 222 is fixed to the side of the rotating column 213. A connecting rod 223 is hinged between the end of the extension rod 222 away from the rotating column 213 and the connecting plate 221.

[0048] The power assembly 31 includes a first motor 311 mounted on the left end of the through column 211 via a motor box. The output end of the first motor 311 passes through the through column 211 and is connected to the front mixing roller 32. Limiting columns 312 are symmetrically installed on the left and right sides of the lower sealing box 3, corresponding to the positions of the rear mixing roller 32. The limiting columns 312 are rotatably connected to the rear mixing roller 32. A rear extension plate 313 is fixed to the side of the rotating column 213. A second motor 314 is mounted on the left side of the rear extension plate 313 via a motor mount. The output end of the second motor 314 passes through the limiting column 312 and is connected to the rear mixing roller 32.

[0049] The support mechanism 2 is not only used to support the lower sealing box 3, but also to rotate the lower sealing box 3 through the rotating structure, thereby ensuring that the lower sealing box 3 can quickly feed the mixed rubber raw materials and rubber compound. At the same time, the support mechanism 2 is also used to install the power component 31 that drives the internal mixing roller 32 to rotate, thereby stably driving the internal mixing roller 32 to rotate through the power component 31.

[0050] Specifically, after the rotating shovel 614 and the inclined scraper 615 remove the rubber raw materials and compounding agents adhering to the front and rear side walls of the upper sealing box 5 and the lower sealing box 3, the first motor 311 and the second motor 314 are controlled to drive the two internal mixing rollers 32 on the front and rear sides to rotate simultaneously, and the rotation directions of the two internal mixing rollers 32 are ensured to be opposite. In this way, the internal mixing rollers 32, in conjunction with the pressure mixing mechanism 4 and the sealing block 613, fully mix and react the rubber raw materials and compounding agents evenly.

[0051] After the mixing roller 32, in conjunction with the pressure mixing mechanism 4 and the sealing block 613, completes the mixing of the rubber raw materials and compounding agents, the control cylinder 220 drives the connecting plate 221 to move forward. This, in turn, drives the rotating column 213 to rotate through the connecting plate 221 and the connecting rod 223. The rotating column 213 and the through column 211 then drive the entire lower sealing box 3 to rotate, which in turn causes the lower sealing box 3 to rotate forward to the discharge position. The first motor 311 and the second motor 314 are continuously controlled to drive the two mixing rollers 32 to rotate, thereby discharging the mixed rubber material.

[0052] See Figures 7-10 Inside the lower sealing box 3 and below the mixing roller 32, there is a protrusion in the middle position, which cooperates with the sealing block 613. The pressure mixing mechanism 4 includes an arc-shaped groove 41 opened inside the lower sealing box 3. A pressure block 411 is slidably connected in the arc-shaped groove 41. A clearance groove is symmetrically arranged in front and behind the arc-shaped groove 41. An inner extension plate 412 is fixed on the front and back sides of the pressure block 411 and at the position corresponding to the clearance groove. Multiple return springs are connected between the inner extension plate 412 and the bottom of the clearance groove. Multiple rotating components 42 are evenly arranged in the pressure block 411. A transmission component 43 for driving the rotating components 42 is connected between the pressure block 411 and the arc-shaped groove 41.

[0053] The rotating component 42 includes multiple sets of horizontally arranged rotating rods 421 rotatably mounted at the bottom of the arc-shaped groove 41. Each rotating rod 421 slides through the pressure block 411. Rotating plates 422 are symmetrically arranged on the side of the rotating rods 421. The pressure block 411 has a receiving groove for accommodating the rotating plates 422. The transmission component 43 includes a connecting column 431 rotatably mounted at the bottom of the arc-shaped groove 41 and corresponding to each set of rotating rods 421. A transmission belt 432 is connected between the connecting column 431 and each set of rotating rods 421. A reset torsion spring is connected between the connecting column 431 and the arc-shaped groove 41. A matching block 433 is connected to the top of the connecting column 431 through a disc. A trapezoidal block 434 is fixed at the bottom of the pressure block 411 and corresponding to each matching block 433.

[0054] The pressure mixing mechanism 4 can avoid the pressure block 411 after it is subjected to sufficient rubber raw material, and uniformly mix the rubber raw material and compounding agent through the rotating component 42 and the transmission component 43. This reduces the risk of a large amount of rubber raw material and compounding agent agglomeration, which would make it difficult for the mixing roller 32 to drive the rubber raw material and compounding agent to rotate and mix. At the same time, it improves the mixing efficiency and effect of rubber raw material and compounding agent. Furthermore, by mixing the rubber raw material and compounding agent through the rotating plate 422 which is converging by the receiving tank, it can prevent the rubber raw material and compounding agent from adhering to the rotating plate 422 or rotating rod 421 during the mixing process, thereby further ensuring that the amount of rubber raw material and compounding agent during the mixing process meets the preset ratio.

[0055] Specifically, during the internal mixing process of the internal mixing roller 32, the rubber raw materials and compounding agents gradually react and agglomerate. When a large amount of rubber raw materials and compounding agents agglomerate, they will press the pressure block 411 as the internal mixing roller 32 rotates to the position of the pressure block 411, causing the pressure block 411 to move into the arc groove 41. At this time, the trapezoidal block 434 will move along with the pressure block 411 until the trapezoidal block 434 contacts the coordination block 433. The trapezoidal block 434 will then push the coordination block 433 and cause the disc and connecting column 431 to rotate.

[0056] Before the connecting column 431 rotates, as the pressure block 411 moves into the arc groove 41, the rotating plate 422 will be pushed open by the rubber raw material and compounding agent, and the rotating plate 422 will gradually detach from the receiving groove until the rotating rod 421 and the rotating plate 422 can rotate freely. With the rotation of the connecting column 431, the transmission belt 432 will synchronously drive each set of horizontally arranged rotating rods 421 to rotate, thereby achieving further mixing of the rubber raw material and compounding agent and promoting the reaction of the rubber raw material and compounding agent through the rotating rod 421 and the open rotating plate 422.

[0057] It should be noted that in order to ensure that the transmission belt 432 can drive the rotating rod 421 to rotate synchronously, the transmission belt 432 should be set as a synchronous belt, and both the rotating rod 421 and the connecting column 431 should be provided with toothed grooves that cooperate with the transmission belt 432.

[0058] See Figure 1 A method for producing and processing a high wear-resistant rubber roller, the method specifically includes the following steps: S1, processing of the rubber roller mandrel: firstly, the mandrel blank is initially formed by forging or rolling, then the initially formed mandrel blank is rough processed by turning the circle and end face, and then the mandrel surface is finely processed by grinding.

[0059] S2. Preparation of raw materials for rubber compound: Prepare the ingredients for the rubber compound in sequence, and use precise measurement to ensure that the proportions of the various ingredients in the rubber compound meet the requirements.

[0060] S3. Rubber compound mixing: First, at the feed inlet 51, the pre-prepared rubber raw materials and various compounding agents are added sequentially into the space formed by the upper sealing box 5 and the lower sealing box 3. Then, the sealing mechanism 6 is controlled to cooperate with the lower sealing box 3 to complete the sealing of the rubber raw materials and compounding agents. During the sealing process of the sealing mechanism 6, the rotating shovels 614 on the front and rear sides will simultaneously scrape the side walls of the upper sealing box 5 and the lower sealing box 3 to remove the rubber raw materials and compounding agents, and return the scraped rubber raw materials and compounding agents to the position of the mixing roller 32, thereby ensuring that the amount of rubber raw materials and compounding agents in the mixing process conforms to the preset ratio.

[0061] After the sealing mechanism 6 is closed, the power component 31 drives the two internal mixing rollers 32 to rotate in opposite directions, thereby fully mixing and reacting the rubber raw materials and compounding agents through the internal mixing rollers 32. During the mixing and reaction process, the pressure mixing mechanism 4 will be subjected to the pressure of a large number of agglomerated rubber raw materials and compounding agents, thereby avoiding and further mixing the agglomerated rubber raw materials and compounding agents through the pressure mixing mechanism 4, thus ensuring the mixing effect and mixing efficiency of the compounding agents.

[0062] After all the rubber raw materials and compounding agents have been internally mixed, the control and sealing mechanism 6 returns to its original position. Then, the support mechanism 2 drives the lower sealing box 3 to rotate and cooperates with the mixing roller 32 to discharge the internally mixed rubber compound. After the discharge is completed, the rubber compound is subjected to subsequent open milling operations.

[0063] S4. Coating: The rubber compound, after being processed, is coated onto the rubber roller mandrel by extrusion coating, ensuring that the rubber compound and the rubber roller mandrel are in close contact.

[0064] S5. Vulcanization treatment: The rubber rollers with rubber coating are vulcanized in a vulcanizing tank until the wear resistance and strength of the rubber rollers meet the requirements for use.

[0065] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered within the protection scope of the present invention.
