Description

Technical Field

[0001] This utility model relates to the field of roller devices for mixing, and in particular to a roller device for rubber mixing. Background Technology

[0002] The rubber mixing drum unit is a core piece of equipment in rubber processing. It applies shearing, extrusion, and stretching actions to the rubber through two relatively rotating heating / cooling drums, simultaneously breaking down the molecular chains of natural rubber, reducing Mooney viscosity, uniformly dispersing additives such as carbon black, vulcanizing agents, and antioxidants, and eliminating air bubbles and localized component differences. The core structure consists of the drum body, drive system, spacing adjustment device, and temperature control system.

[0003] Existing technologies, such as the utility model patent with publication number CN212978857U, disclose a rubber processing mixing device, including a mixing mill support and a silver-plated roller. A plain mill support is located on the left side of the mixing mill support, and a heating roller is located inside the plain mill support. An emergency stop knob mounting groove is located on the left side of the plain mill support. The silver-plated roller is located inside the mixing mill support, and a rotating shaft passes through the interior of the silver-plated roller. A motor is located at the right end of the rotating shaft, and a controller is located at the upper right end of the motor. A compounding agent tank is located at the upper left end of the mixing mill support, and a slider is located at the lower end of the compounding agent tank. The hose is connected to the mixing mill support via a hanging rod, forming a locking structure. The top of the hanging rod is glued to the upper inner surface of the mixing mill support, allowing the hose to pass through the hanging rod and connect to the compounding agent outlet. This reduces the load on the connection point between the hose and the mixing mill support and the compounding agent outlet, thereby reducing breakage and extending service life.

[0004] The inventors discovered in daily use that when operating the rubber mixing drum device, the rubber is placed between two drums and mixed. A scraper is used to cut the rubber to ensure thorough mixing. However, this causes the rubber to fall onto the machine surface, which is difficult to clean and results in waste. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology where, when operating a rubber mixing drum device, the rubber is placed between two drums for mixing and a scraper is used to cut the rubber to ensure thorough mixing. However, this process results in rubber falling onto the machine surface, which is difficult to clean and wastes rubber.

[0006] To solve the above technical problems, this utility model provides a roller device for rubber mixing, comprising: a machine body, a bracket fixedly connected to the upper surface of the machine body, two rollers rotatably connected to the inner wall of the bracket, a cleaning device provided on the upper surface of the machine body, the cleaning device including a first motor and a cleaning plate, the lower surface of the first motor fixedly connected to the machine body, a lead screw fixedly connected to the output end of the first motor, the other end of the lead screw rotatably passing through a support block, the lower surface of the support block fixedly connected to the machine body, one end of the cleaning plate threaded through the lead screw, and the other end of the cleaning plate rotatably passing through a limit rod.

Two slots are opened on the surface of the cleaning plate. The cross-section of the two slots is "L". A card plate is engaged with the inner wall of the slot. A brush plate is fixedly connected to the end of the card plate away from the cleaning plate. A moving block is slidably connected to the cleaning plate at the position corresponding to the two slots. The cross-section of the moving block is "U". The inner wall of the moving block abuts against the card plate. Two support frames are fixedly connected to the side of the body away from the cleaning plate. The cross-section of the two support frames is "L". A storage box abuts against the upper surface of the support frame.

[0007] The effect achieved by the above components is as follows: When it is necessary to clean the rubber that has fallen onto the upper surface of the machine body, first install the brush plate, so move the two moving blocks to the middle, then place the card plate on the brush plate into the corresponding slot so that they engage, then move the two moving blocks to the slot so that the moving blocks abut against the card plate, and at the same time place the storage box on the support frame, then start the first motor so that the first motor drives the lead screw to rotate, so that the cleaning plate moves with the brush plate towards the storage box. At the same time, the cleaning plate slides along the limit rod to achieve the limiting effect, thus pushing the rubber into the storage box. Then move the storage box to process the rubber.

[0008] Preferably, a limiting block is fixedly connected to the upper surface of the cleaning plate, and a telescopic rod is fixedly connected to both ends of the limiting block. A fixing block is fixedly connected to the ends of the two telescopic rods that are far apart from each other. The lower surface of the fixing block is fixedly connected to the moving block. A first spring is sleeved on the arc surface of the telescopic rod, and the two ends of the first spring are fixedly connected to the limiting block and the fixing block, respectively.

[0009] The effect achieved by the above components is that when the moving block is moved, the first spring provides elastic force to restore the moving block to its original shape, making it more convenient and effortless.

[0010] Preferably, a pull ring is fixedly connected to one end of each of the two fixed blocks that is far from each other, and the pull ring has a circular cross-section.

[0011] The effect achieved by the above components is that the moving block can be moved with the help of the pull ring, which is more convenient.

[0013] The effect achieved by the above components is that the storage box can be moved more conveniently with the help of the handle.

[0014] Preferably, the upper surface of the bracket is provided with a cutting device, the cutting device including a second motor, the surface of the second motor being fixedly connected to the bracket, the output end of the second motor being fixedly connected to a screw, the bottom end of the screw being rotatably connected to the bracket, the arc surface of the screw threaded through a movable plate, the end of the movable plate away from the second motor slidingly passing through a limit post, the lower surface of the limit post being fixedly connected to the bracket, two fixed plates being fixedly connected to both ends of the movable plate, wherein the two fixed plates are slidably connected to the same slider on the side close to each other, the surface of the slider being fixedly connected to a connecting plate, the connecting plate... A stop block is fixedly connected to the upper surface of the connecting plate. A round rod is slidably connected to the inner wall of the stop block. A cutting block is fixedly connected to the lower surface of the round rod. The cutting block has a wedge-shaped cross-section. Both ends of the upper surface of the cutting block are rotatably connected to a locking block. Limiting grooves are formed on both sides of the connecting plate. The cross-sectional dimensions of the limiting grooves are adapted to the cross-sectional dimensions of the locking blocks. A second spring is sleeved on the arc surface of the round rod. The two ends of the second spring are fixedly connected to the stop block and the cutting block, respectively. The upper surfaces of the two round rods are fixedly connected to the same connecting block. A threaded rod is threaded through the inner wall of the connecting block. The bottom end of the threaded rod abuts against the moving plate.

[0015] The effect achieved by the above components is as follows: when rubber needs to be cut during rubber compounding, the threaded rod is first pulled out, so that the connecting block and the round rod move downwards, and the cutting block moves downwards at the same time. The second spring provides elastic force to buffer the cutting block and prevent it from falling too fast. Then, the locking block is rotated to adjust the position of the cutting block so that the locking block is locked into the limiting groove. Then, the second motor is controlled to rotate the screw and move the moving plate up and down. Then, the sliding block is moved along the direction of the fixed plate by moving the connecting block, so that cutting can be performed.

[0016] Preferably, anti-slip pads are fixedly connected to the sides of the two fixed plates that are close to each other, and the anti-slip pads are rubber pads.

[0017] The effect achieved by the above components is that the anti-slip pad can increase the friction on the slider, thereby enabling better positioning.

[0019] The effect achieved by the above components is that when the cutting block moves, the sliding block moves along the sliding groove, which plays a guiding role.

[0020] Compared with related technologies, the rubber mixing drum device provided by this utility model has the following advantages:

[0021] Beneficial effects:

[0022] This utility model provides a roller device for rubber mixing. When rubber falls onto the machine surface during mixing and needs to be removed, the brush plate is first installed on the cleaning plate. A pull ring is used to move two fixed blocks closer together, along with a moving block. Then, two locking plates on the brush plate are placed in the locking slots to engage. The pull ring is then released, and a first spring provides elasticity, causing the moving block to move in the opposite direction. This allows the moving block to abut against the locking plates, thus securing the brush plate. The collection box is then moved by the handle to a position on the support frame. A first motor rotates the lead screw, moving the cleaning plate and brush plate to clean the machine surface until the rubber is pushed into the collection box. The rubber in the collection box is then processed. This operation of the cleaning device effectively removes rubber that has fallen onto the machine surface.

[0023] When cutting rubber during rubber compounding, first pull out the threaded rod, causing the connecting block and round rod to fall downwards. Simultaneously, the cutting block moves downwards with it. The second spring provides elasticity, cushioning the downward fall of the cutting block. Then, rotate the locking block while adjusting the position of the cutting block, locking it into the limiting groove. This fixes the cutting block in place. Next, the second motor drives the screw to rotate, causing the moving plate to move up and down until the cutting block can cut the rubber. Finally, move the connecting block to move the cutting block further, cutting the rubber. Through the operation of this cutting device, the rubber cutting function is achieved.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0034] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 and Figure 4The cleaning device 4 includes a first motor 401 and a cleaning plate 403. The lower surface of the first motor 401 is fixedly connected to the machine body 1. A lead screw 402 is fixedly connected to the output end of the first motor 401. The other end of the lead screw 402 rotatably passes through a support block 414. The lower surface of the support block 414 is fixedly connected to the machine body 1. One end of the cleaning plate 403 is threaded through the lead screw 402. The other end of the cleaning plate 403 rotatably passes through a limit rod 404.

The surface of the cleaning plate 403 has an opening... Two slots 406, each with an "L" shaped cross-section, are fitted with a card plate 407 on the inner wall of each slot 406. A brush plate 405 is fixedly connected to the end of the card plate 407 away from the cleaning plate 403. A moving block 408 is slidably connected to each of the two slots 406 on the cleaning plate 403. The moving block 408 has a "U" shaped cross-section and its inner wall abuts against the card plate 407. Two support frames 416 are fixedly connected to the side of the body 1 away from the cleaning plate 403. Both support frames 416 have an "L" shaped cross-section and their upper surfaces abut against a storage box 417. When it is necessary to clean the rubber that has fallen onto the upper surface of the machine body 1, first install the brush plate 405, so move the two moving blocks 408 towards the center, then place the retaining plate 407 on the brush plate 405 into the corresponding slot 406 so that they engage. Then move the two moving blocks 408 to the slot 406 so that the moving blocks 408 abut against the retaining plate 407. At the same time, place the storage box 417 on the support frame 416, then start the first motor 401 to drive the lead screw 402 to rotate. In this way, the cleaning plate 403 moves the brush plate 405 towards the storage box 417. At the same time, the cleaning plate 403 slides along the limiting rod 404 to achieve a limiting effect, thus pushing the rubber into the storage box 417. Then move the storage box 417 to process the rubber. A limiting block 412 is fixedly connected to the upper surface of the cleaning plate 403. Telescopic rods 411 are fixedly connected to both ends of the limiting block 412. Fixed blocks 409 are fixedly connected to the ends of the two telescopic rods 411 that are furthest from each other. The lower surface of the fixed blocks 409 is fixedly connected to the moving block 408. A first spring 413 is fitted onto the arc surface of the telescopic rods 411. The two ends of the first spring 413 are fixedly connected to the limiting block 412 and the fixed blocks 409, respectively. When the moving block 408 is moved, the first spring 413 provides elastic force, allowing the moving block 408 to return to its original shape, making it more convenient and effortless. A pull ring 410 is fixedly connected to the ends of the two fixed blocks 409 that are furthest from each other. The pull ring 410 has a circular cross-section. The moving block 408 can be moved using the pull ring 410, making it more convenient. A handle 418 is fixedly connected to the side of the storage box 417 furthest from the body 1. The handle 418 has a U-shaped cross-section. The storage box 417 can be moved more conveniently using the handle 418;

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 The cutting device 5 includes a second motor 502, the surface of which is fixedly connected to the bracket 2. A screw 501 is fixedly connected to the output end of the second motor 502. The bottom end of the screw 501 is rotatably connected to the bracket 2. A movable plate 503 is threaded through the arc surface of the screw 501. The end of the movable plate 503 away from the second motor 502 slides through a limit post 504. The lower surface of the limit post 504 is fixedly connected to the bracket 2. Two fixed plates 505 are fixedly connected to both ends of the movable plate 503. A slider 507 is slidably connected to the side of the two fixed plates 505 that is close to each other. A connecting plate 508 is fixedly connected to the surface of the slider 507. A stop block 509 is fixedly connected to the upper surface of the connecting plate 508. A round rod 510 is slidably connected to the inner wall of the stop block 509. A cutting block 512 is fixedly connected to the lower surface of the round rod 510. The cross-section of the cutting block 512 is wedge-shaped. Both ends of the upper surface of the cutting block 512 are rotatably connected to the locking blocks 514. Limiting grooves 515 are opened on both sides of the connecting plate 508. The cross-sectional dimensions of the limiting grooves 515 and the cross-sectional dimensions of the locking blocks 514 are adapted to each other. A second spring 513 is sleeved on the arc surface of the round rod 510. The two ends of the second spring 513 are fixedly connected to the stop block 509 and the cutting block 512 respectively. The upper surfaces of the two round rods 510 are fixedly connected to the same connecting block 511. A threaded rod 518 is threaded through the inner wall of the connecting block 511. The bottom end of the threaded rod 518 abuts against the moving plate 503. When cutting rubber during rubber compounding, first pull out the threaded rod 518. This causes the connecting block 511 and the round rod 510 to move downwards, while the cutting block 512 moves downwards simultaneously. The second spring 513 provides elasticity and cushioning to prevent the cutting block 512 from falling too quickly. Then, rotate the locking block 514 to adjust the position of the cutting block 512, so that the locking block 514 engages with the limiting groove 515. Then, control the second motor 502 to rotate the screw 501, causing the moving plate 503 to move up and down. Then, by moving the connecting block 511, the slider 507 moves along the direction of the fixed plate 505, thus enabling cutting. Anti-slip pads 506, made of rubber, are fixedly connected to the sides of the two fixed plates 505 that are close to each other. The anti-slip pads 506 increase the friction on the slider 507, thus allowing for better positioning. A sliding block 517 is fixedly connected to the side of the cutting block 512 near the connecting plate 508. A sliding groove 516 is provided on the connecting plate 508 corresponding to the position of the sliding block 517. The inner wall of the sliding groove 516 is slidably connected to the sliding block 517. When the cutting block 512 moves, the sliding block 517 moves along the sliding groove 516, which serves as a guide.

[0036] The working principle of the rubber mixing roller device provided by this utility model is as follows: When rubber falls onto the surface of the machine body 1 during rubber mixing and needs to be cleaned, the brush plate 405 is first installed on the cleaning plate 403. Therefore, the two fixed blocks 409 are moved closer to each other by means of the pull ring 410, which also moves the moving block 408 closer to each other. Then, the two clamping plates 407 on the brush plate 405 are placed in the clamping groove 406 to lock them in place. Then, the pull ring 410 is released. The first spring 413 provides elastic force, causing the moving block 408 to move in the opposite direction. This allows the moving block 408 to abut against the plate 407, fixing both the plate and the brush plate 405. Then, the handle 418 moves the storage box 417, positioning it on the support frame 416. The first motor 401 rotates the lead screw 402, moving the cleaning plate 403 and the brush plate 405 to clean the surface of the machine body 1 until the rubber is pushed into the storage box 417. The rubber inside the storage box 417 is then processed. In this way, by operating the cleaning device 4, the rubber that has fallen onto the surface of the machine body 1 is effectively removed.

[0037] When cutting rubber during rubber compounding, first pull out the threaded rod 518, causing the connecting block 511 and the round rod 510 to fall downwards. Simultaneously, the cutting block 512 moves downwards. The second spring 513 provides elasticity, cushioning the downward fall of the cutting block 512. Then, rotate the locking block 514, adjusting the position of the cutting block 512 until it engages with the limiting groove 515, thus fixing the cutting block 512. Next, the second motor 502 drives the screw 501 to rotate, causing the moving plate 503 to move up and down until the cutting block 512 can cut the rubber. Finally, move the connecting block 511 to move the cutting block 512, cutting the rubber. Through the operation of the cutting device 5, the rubber cutting function is achieved.
