Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of rubber mixing machines, and more specifically, to a rubber mixing machine for processing rubber products. Background Technology

[0002] In the rubber product manufacturing process, the mixing mill is a key piece of equipment for achieving uniform mixing and plasticizing of rubber raw materials and compounding agents (such as vulcanizing agents and fillers). Its mixing efficiency and ease of operation directly determine the quality and production progress of the subsequent vulcanization molding process. As rubber products develop towards large-scale and standardized production, the shortcomings of traditional mixing mills are becoming increasingly apparent: existing mixing mills generally rely on manual cutting of rubber materials, and repeated manual re-applying of rubber is required during the mixing process. This not only increases the labor intensity of operators but also easily leads to prolonged mixing cycles and unstable rubber material quality, making it difficult to meet the demands of high-efficiency production. Traditional rubber mixing mills typically employ an open double-roller structure. After the rubber raw material is repeatedly crushed and mixed between the rollers until homogeneous, it must be manually cut off from the rollers using hand-held cutters. If the mixture is uneven, the cut material must be manually placed back between the rollers for remixing. This entire process requires continuous manual monitoring. Manual cutting is not only inefficient but also prone to uneven block size due to inconsistent cutting force and angle, affecting subsequent feeding accuracy. Repeated manual application of rubber prolongs the mixing time per cycle, and manual contact with the rubber can introduce impurities or lead to insufficient mixing due to inaccurate application positions, causing fluctuations in rubber properties. Therefore, the development of rubber mixing machines that can reduce manual intervention and eliminate the need for manual cutting and repeated gluing has become an urgent need to improve production efficiency and the stability of rubber quality. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a rubber mixing machine for processing rubber products, which solves the technical problems that existing rubber mixing machines generally rely on manual cutting of rubber materials and require repeated manual re-applying of rubber during the mixing process, which not only increases the labor intensity of operators, but also easily leads to a longer mixing cycle and unstable rubber material quality.

[0004] According to one aspect, at least one embodiment of this disclosure provides a rubber mixing mill for processing rubber products, comprising: The machine body and a pair of uprights, the uprights being fixed to both ends of the surface of the machine body; A pair of rubber mixing rollers and a drive adjustment assembly, wherein the rubber mixing rollers are both disposed between the uprights, and the drive adjustment assembly is disposed between the rubber mixing rollers and the uprights; A cutting and gluing assembly is disposed on the top of the stand; The cutting and gluing assembly includes a pair of connecting seats, both of which are located on the top of the stand. A rotating shaft is rotatably connected between the connecting seats. The rotating shaft is driven to rotate by electricity. A transmission groove is provided on the side end face of the rotating shaft. A moving block is connected to the transmission groove by a horizontal linear drive. A cutter is provided on the side end face of the moving block.

[0005] As a further technical solution, each of the bases has an outer groove on its top, and a pair of guide rods are provided in the outer groove. The connecting seat is horizontally slidably fitted onto the guide rods, and a through hole is provided on the side surface of the connecting seat.

[0006] As a further technical solution, an inner rod is horizontally fixedly connected inside the outer groove, the inner rod is inserted into the through hole, a locking cylinder is horizontally fixedly connected to the outside of the connecting seat, the output end of the locking cylinder is supported on the side end face of the inner rod, and a shovel plate is installed on the rotating shaft frame.

[0007] According to another aspect, in at least one embodiment of the present invention, the drive adjustment assembly includes a pair of through cavities, the through cavities being opened at both ends of the side surface of the stand, and a pair of stabilizing rods being horizontally fixedly connected in each through cavity, with stabilizing seats slidably fitted onto the pair of stabilizing rods.

[0008] As a further technical solution, the rubber mixing roller is rotatably connected between a pair of stabilizing seats with opposite axes. The rubber mixing roller is driven to rotate by electricity. Adjusting studs are threadedly connected to both sides of one of the upright seats. One end of the adjusting stud is rotatably fitted to the side end face of the stabilizing seat.

[0009] As a further technical solution, one end of the adjusting stud is provided with a screwing block, and the surface of the screwing block is a polygonal structure.

[0010] As a further technical solution, the cutting blade tip has a planar blade structure.

[0011] As a further technical solution, the side end face of the stabilizing rod is a frosted, anti-slip surface.

[0012] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the cutting and gluing assembly solves the problem of traditional rubber mixing mills relying on manual cutting and gluing through automated tool switching and precise positioning design. The rotating shaft can quickly switch between the cutter and the scraper. The flat blade of the cutter ensures a clean cut of the rubber material, while the scraper adapts to the curvature of the mixing roller for smooth gluing. The connecting seat moves along both the guide rod and the inner rod, and is locked in place by a locking cylinder, ensuring precise tool positioning and preventing rubber waste due to deviation. This structure eliminates the need for manual tool handling, significantly reducing labor intensity. It also prevents manual contact with the rubber material from introducing impurities, shortens the mixing cycle, ensures stable rubber quality, and meets the needs of large-scale rubber mixing, providing uniform and consistent raw materials for subsequent processing.

[0021] like Figures 1-5 As shown, it illustrates a rubber mixing mill for processing rubber products according to an embodiment of the present disclosure, comprising: The machine body 1 and a pair of uprights 2, wherein the uprights 2 are fixed to both ends of the surface of the machine body 1; A pair of rubber mixing rollers 3 and a drive adjustment assembly 5, wherein the rubber mixing rollers 3 are both disposed between the uprights 2, and the drive adjustment assembly 5 is disposed between the rubber mixing rollers 3 and the uprights 2; Cut the glue application assembly 4, which is disposed on the top of the stand 2; The cutting and gluing assembly 4 includes a pair of connecting seats 4-1, both of which are located on the top of the stand 2. A rotating shaft frame 4-2 is rotatably connected between the connecting seats 4-1. The rotating shaft frame 4-2 is electrically driven to rotate. A transmission groove 4-3 is formed on the side end face of the rotating shaft frame 4-2. A moving block 4-4 is connected to the transmission groove 4-3 via a horizontal linear drive. A cutter 4-5 is provided on the side end face of the moving block 4-4. An outer groove 4-6 is formed on the top of the stand 2. A pair of guide rods 4-7 are provided inside. The connecting seat 4-1 is horizontally slidably connected to the guide rods 4-7. A through hole 4-8 is opened on the side surface of the connecting seat 4-1. An inner rod 4-11 is horizontally fixedly connected inside the outer groove 4-6. The inner rod 4-11 is inserted into the through hole 4-8. A locking cylinder 4-9 is horizontally fixedly connected to the outside of the connecting seat 4-1. The output end of the locking cylinder 4-9 is supported on the side end face of the inner rod 4-11. A shovel plate 4-10 is installed on the rotating shaft frame 4-2.

[0022] In some examples, to achieve efficient switching between rubber cutting and re-gluing, and to avoid the tedious manual tool changing during rubber mixing, a cutting and gluing assembly 4 is designed. This assembly includes a pair of connecting seats 4-1 on the top of the stand 2 to provide mounting support for the rotating shaft frame 4-2. The rotating shaft frame 4-2, which is rotatably connected between the connecting seats 4-1, is driven to rotate by electricity, which can drive the side cutter 4-5 and the surface scraper 4-10 to switch positions. When it is necessary to cut the rubber, the rotating shaft frame 4-2 rotates so that the cutter 4-5 faces the rubber, and the rubber on the mixing roller 3 is cut by the cutter 4-5. When it is necessary to re-glu, the rotating shaft frame 4-2 flips so that the scraper 4-10 is close to the mixing roller 3, and the rubber is scooped up and guided to the appropriate position on the mixing roller 3 by the scraper 4-10, so as to realize automated gluing. The guide rod 4-7 in the outer groove 4-6 at the top of the stand 2 slides and fits with the connecting seat 4-1, providing guidance for the horizontal movement of the connecting seat 4-1. Together with the inner rod 4-11 inserted in the through hole 4-8 of the connecting seat 4-1 in the outer groove 4-6, a double guide structure is formed to ensure that the connecting seat 4-1 moves without deviation when it drives the rotating shaft frame 4-2. The working position of the cutter 4-5 and the shovel plate 4-10 can be adjusted according to the length of the rubber mixing roller 3 to adapt to the processing requirements of rubber materials of different widths.

[0023] The output end of the locking cylinder 4-9 on the outside of the connecting seat 4-1 is supported on the side end face of the inner rod 4-11. When the connecting seat 4-1 is adjusted to the target position, the locking cylinder 4-9 extends and presses against the inner rod 4-11, locking the position of the connecting seat 4-1 through friction, preventing the connecting seat 4-1 from shifting during the rubber mixing process and causing deviation in the tool's action. The electric drive of the rotating shaft 4-2 ensures precise and rapid tool switching, the sharp structure of the cutter 4-5 ensures a smooth cut of the rubber material, and the arc design of the shovel plate 4-10 adapts to the surface curvature of the rubber mixing roller 3, improving the shovel and guiding effect of the rubber material.

[0024] During operation, the movable connecting seat 4-1 is adjusted and locked, while the rotating shaft 4-2 switches to the cutter 4-5 to cut the rubber material or the scraper 4-10 to apply adhesive. Tool switching is automated, position adjustment is precise, and all components work together to complete the cutting and application of rubber material, meeting the needs of rubber compounding and processing.

[0025] like Figures 1-5 As shown, this embodiment proposes that the drive adjustment component 5 includes a pair of through cavities 5-1, which are opened at both ends of the side surface of the stand 2. A pair of stabilizing rods 5-2 are horizontally fixedly connected in each of the through cavities 5-1. Stabilizing seats 5-3 are slidably fitted on the pair of stabilizing rods 5-2. The rubber mixing roller 3 is rotatably connected between the pair of stabilizing seats 5-3 with opposite axes. The rubber mixing roller 3 is driven to rotate by electricity. Adjusting studs 5-4 are threadedly connected to both sides of one side of the stand 2. One end of the adjusting stud 5-4 is rotatably fitted to the side end face of the stabilizing seat 5-3.

[0026] In some examples, in order to achieve precise adjustment of the distance between the two mixing rollers 3 and avoid uneven rubber mixing or equipment damage caused by improper distance, a drive adjustment component 5 is designed. This component includes through cavities 5-1 at both ends of the side surface of the stand 2 to provide installation and sliding space for the stabilizing seat 5-3. A pair of horizontally fixed stabilizing rods 5-2 are slidably fitted with the stabilizing seat 5-3 in the through cavity 5-1 to form a guide structure, ensuring that the stabilizing seat 5-3 drives the mixing roller 3 to move smoothly in the horizontal direction, avoiding tilting or deviation when the mixing roller 3 moves, ensuring that the two mixing rollers 3 always remain parallel, and preventing uneven force on the rubber due to roller body tilt.

[0027] The mixing roller 3 is rotatably connected between a pair of stabilizing seats 5-3 with opposite axes. The movement of the stabilizing seats 5-3 can directly drive the mixing roller 3 to move synchronously, thereby achieving the spacing adjustment. The adjusting studs 5-4 on both sides of one side of the upright seat 2 are threaded together. One end of the stud is rotated and fitted with the side end face of the stabilizing seat 5-3, forming a driving structure. When the adjusting stud 5-4 is turned, the thread transmission drives the stabilizing seat 5-3 to slide along the stabilizing rod 5-2, thereby pushing the mixing roller 3 closer to or away from the other mixing roller 3. By controlling the number of turns of the stud, the spacing adjustment can be precisely controlled to meet the mixing requirements of rubber materials of different thicknesses and hardnesses.

[0028] The symmetrical distribution of the stabilizing rods 5-2 ensures that the stabilizing seat 5-3 is subjected to balanced force, preventing deformation of the stabilizing seat 5-3 after long-term use; the self-locking thread of the adjusting stud 5-4 can automatically lock the position of the stabilizing seat 5-3 after the spacing is adjusted, preventing the spacing from shifting due to vibration during rubber mixing; the electric drive of the rubber mixing roller 3 ensures its stable rotation and provides continuous power for rubber mixing.

[0029] During operation, turning the adjusting stud 5-4 moves the stabilizing seat 5-3 and the mixing roller 3. Once the target spacing is reached, rubber mixing can begin. The spacing adjustment is precise, the structure is stable, and all components work together to adjust the spacing of the mixing roller 3, meeting the requirements of rubber mixing processing.

[0030] For example, such as Figure 1 As shown, one end of the adjusting stud 5-4 is provided with a screw block 6, and the surface of the screw block 6 is a polygonal structure.

[0031] In some examples, the polygonal screw block 6 at one end of the adjusting stud 5-4 provides the operator with a convenient point of force application, making it easy to tighten the adjusting stud 5-4 with tools (such as wrenches) or by hand. Compared to the circular screw block 6, the polygonal structure prevents tool slippage, ensures stable force transmission during tightening, accurately controls the number of turns of the stud, and thus precisely adjusts the gap of the rubber mixing roller 3.

[0032] For example, such as Figure 5 As shown, the front end of the cutter 4-5 has a planar blade structure.

[0033] In some examples, the flat blade structure at the tip of cutter 4-5 ensures a smooth cut surface for the rubber material, preventing tearing, burrs, and other problems caused by improper blade shape during cutting. The uniform contact area between the flat blade and the rubber material allows for smooth application of cutting force through linear drive, making it particularly suitable for thicker or more resilient rubber materials, preventing the rubber material from sticking to the blade or resulting in incomplete cutting during the cutting process.

[0034] For example, such as Figure 4 As shown, the side end face of the stabilizing rod 5-2 has a frosted, anti-slip structure.

[0035] In some examples, the frosted anti-slip surface of the side end face of the stabilizing rod 5-2 can increase the friction at the sliding connection between the stabilizing rod 5-2 and the stabilizing seat 5-3. The vibration generated during the operation of the rubber mixing mill can easily cause the stabilizing seat 5-3 to slide slightly along the stabilizing rod 5-2, which in turn affects the stability of the gap between the rubber mixing rollers 3. The frosted anti-slip surface can limit this sliding through friction, ensuring that the stabilizing seat 5-3 is fixed in position.

[0036] In practical use: Based on the rubber compounding requirements, tighten the polygonal screw block 6 of the adjusting stud 5-4 to drive the stabilizing seat 5-3 to slide along the stabilizing rod 5-2 within the cavity 5-1, adjusting the distance between the pair of mixing rollers 3. The frosted stabilizing rod 5-2 ensures the stability of the stabilizing seat 5-3. Start the electric drive of the mixing rollers 3 and place the rubber raw material between them for mixing. When cutting the rubber compound, slide the connecting seat 4-1 at the top of the upright 2, adjusting it to the target position along the guide rod 4-7 and inner rod 4-11. Locking cylinder 4-9 presses against the inner rod 4-11 to lock the connecting seat 4-1. The electric drive rotates the shaft frame 4-2, causing the cutter 4-5 to face the rubber compound. The horizontal linear drive drives the moving block 4-4 and the cutter 4-5 to cut the rubber compound. When re-applying rubber, the rotating shaft frame 4-2 flips to switch to the shovel plate 4-10. The shovel plate 4-10 approaches the mixing roller 3, guiding the rubber compound to the appropriate position, completing the secondary mixing without manual intervention. The entire process is automated through component linkage, which reduces manual operation and ensures continuous rubber mixing.
