Description

Technical Field

[0001] This invention belongs to the field of rubber processing technology, and specifically relates to a granulation screening device for rubber processing. Background Technology

[0002] The rubber industry is one of the important basic industries of the national economy. It not only provides essential daily-use and medical rubber products, but also supplies various rubber-made production equipment and components to heavy industries and emerging industries such as mining, transportation, construction, machinery, and electronics. It is evident that the rubber industry offers a wide variety of products and has a broad downstream industry reach. With the rapid development of modern industry, especially the chemical industry, rubber products are diverse, but their production processes are basically the same. For products made from general solid rubber (raw rubber), the main production process includes: raw material preparation → plasticizing → mixing → molding → vulcanization → finishing → inspection. Currently, in the screening of rubber raw material particles, due to the elasticity of rubber raw materials, particles can clog the sieve apertures. When the sieve becomes clogged, the screening efficiency is undoubtedly reduced, and the machine must be stopped immediately when the screening efficiency is low to replace or unclog the sieve before production can continue. This causes inconvenience and inefficiency in rubber production. Summary of the Invention

[0003] The purpose of this invention is to provide a particle screening device for rubber processing. Its advantages include ensuring the efficiency of particle screening, effectively improving the efficiency of clearing blocked particles, bringing security and convenience to the production of rubber raw material particles in the workshop, replacing the inconvenience of manual cleaning; ensuring the clearing effect of the impacting parts; improving practicality, avoiding the leakage of particles during penetration and movement, and ensuring the use of particle screening.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a granulation device for rubber processing, a vibration assembly, the vibration assembly including a housing, and a screening assembly disposed inside the vibration assembly;

[0005] The outer side of the screening component is provided with a moving component, the moving component includes an internal gear, an external gear meshing with the inner side of the internal gear, a rod fixedly sleeved inside the external gear, a shaft fixedly installed on the top of the rod, a moving ring sleeved on the surface of the shaft, a striking component and a blocking component respectively provided on one side of the moving ring, and a return component provided on the top of the moving ring.

[0006] The screening assembly includes an inner shell. A feed pipe extending through to the top of the outer shell is fixedly installed on the top of the inner shell, and a discharge pipe extending through to the bottom of the outer shell is fixedly installed on the bottom of the inner shell. A sieve plate is bolted to the inner side of the inner shell. A discharge frame extending through to the outer side of the outer shell is fixedly installed on one side of the inner shell, above the sieve plate. The feed pipe, discharge pipe, and discharge frame are all fixedly connected to the outer shell. Ring body one and ring body two are rotatably connected to the surface of the inner shell via bearings. Support plates one are installed at equal intervals on the outer side of ring body one, and support plates two are installed at equal intervals on the outer side of ring body two. Support plate two, a slider one is fixedly installed at one end of both support plate one and support plate two, a groove one is opened on the inner side of the outer shell to cooperate with the slider one to slide, the internal gear is fixedly connected to the inner side of the outer shell, a rotating motor is fixedly installed on the top of support plate two on one side of the inner shell, the output end of the rotating motor is fixedly connected to the rod body through a coupling, the surface of the shaft body is respectively opened with inclined groove and vertical groove, the inclined groove and vertical groove are connected to each other, the inner side of the moving ring is opened with a snap-fit ​​component, the snap-fit ​​component is used to snap-fit ​​with the inclined groove and vertical groove respectively;

[0007] The return assembly includes two guide rods. Each side of a support plate located on one side of the inner shell has a second side lug that is sleeved on the surface of the guide rod. The second side lug is slidably connected to the guide rod. The bottom of the guide rod is fixedly installed with a first side lug that is fixedly connected to a shift ring. A contraction spring is sleeved on the surface of the guide rod. The two ends of the contraction spring are fixedly connected to the first and second side lugs, respectively. A limit plate is fixedly installed on the top of the guide rod.

[0008] Using the above technical solution, when using the granulation device for rubber processing, the operator first feeds the raw rubber particles into the screening component, and then the screening of the raw material particles is achieved through the setting of the vibration component. When particles become stuck or blocked, the movement of the moving component drives the impact component to move longitudinally. Simultaneously, the impact component can move around a central point, increasing the unblocking effect of the particles. This setting ensures the efficiency of particle screening and effectively improves the unblocking efficiency of blocked particles, bringing guarantee and convenience to the production of raw rubber particles in the workshop. Furthermore, the return component is designed to provide a greater impact force to the impact component, effectively ensuring the unblocking effect of the impact component. At the same time, the shielding component, based on the above principles, provides a shielding and protective effect for particle screening, improving the practicality of the mechanism and preventing leakage of particles during penetration and movement, thus ensuring the use of the particle screening system.

[0009] The present invention is further configured such that: a support leg 1 is fixedly installed on the outer side of the outer shell, a support leg 2 is provided at the bottom of the support leg 1, a support spring is fixedly installed between the support leg 1 and the support leg 2, and a vibration motor is fixedly bolted to the surface of the outer shell.

[0010] Using the above technical solution, the operation of the vibration motor will cause the outer shell to vibrate. The support spring, together with the support leg one and the support leg two, provides support and prevents the vibration amplitude from being transmitted to the support leg two, so as to avoid the instability of the support leg two.

[0011] The present invention is further configured such that: the striking assembly includes a striking member, the striking member is located inside the inner shell, a connecting rod is fixedly installed on one side of the striking member and extends to the outside of the inner shell, and an annular groove is provided inside the inner shell to cooperate with the connecting rod.

[0012] Using the above technical solution, the striking component works in conjunction with the bottom of the screen plate to strike, thereby promoting the smooth discharge of particles stuck in the screen plate aperture. The annular groove, in conjunction with the connecting rod, penetrates the inner shell while ensuring the circular movement of the connecting rod.

[0013] The present invention is further configured such that: a mounting block is rotatably connected to the outer side of the first connecting rod via a rotating shaft; a second connecting rod is fixedly installed at one end of the first connecting rod; a second mounting block is rotatably connected to one end of the second connecting rod via a rotating shaft; and the second mounting block and the moving ring are fixedly connected to each other.

[0014] Using the above technical solution, mounting block two will facilitate the angle adjustment between connecting rod two and the shifting ring. When the shifting ring moves longitudinally, it will drive the first end of connecting rod one and the striking part to change height through the lever principle. Mounting block one works with connecting rod one to adjust the angle, and the first end of connecting rod one and the striking part will work with mounting block one as the center to change the angle.

[0015] The invention is further configured such that: the shielding assembly includes a collar, the collar being sleeved on the surface of the inner shell, a fitting block being embedded in the inner side of the collar and sleeved on the surface of a connecting rod, the fitting block and the mounting block being fixedly connected to each other, the surface of the collar having an inclined groove located on one side of the fitting block, the inclined groove being used in conjunction with the connecting rod, and sliders being fixedly installed on the surface of the inner shell at both the top and bottom of the annular groove, and the inner side of the collar having a sliding groove for sliding with sliders.

[0016] Using the above technical solution, the collar will move and be guided on the inner shell surface through the setting of slider two and groove two. While the moving ring is moving in a circle, the connecting rod one will simultaneously drive the mating block sleeved on its surface to move. The mating block will also drive the collar to rotate on the inner shell surface. The setting of the inclined groove will ensure sufficient space for the connecting rod one to adjust the angle, which is convenient for the use of the connecting rod one.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1. When using a granulation screening device for rubber processing, the striking element is designed to both strike longitudinally and move in position, causing it to move around the center of the internal gear. This increases the uniformity of the impact on the bottom of the screen plate, thereby improving the removal of clogging particles. This design ensures efficient particle screening and effectively improves the removal of clogging particles, providing assurance and convenience for the production of rubber raw materials in the workshop. Furthermore, this process can be performed during particle screening without stopping the machine, increasing screening efficiency and eliminating the inconvenience of manual cleaning.

[0019] 2. When using the sieving device for rubber processing, the setting of side ear one, side ear two and the compression spring can ensure that side ear two returns to the initial position and will bring a large impact force to the impacting part, which can effectively ensure the impact and unblocking effect of the impacting part.

[0020] 3.

The snap-fit ​​piece 309 is used to snap-fit ​​with the inclined groove 307 and vertical groove 308 respectively.

[0041] The return assembly 5 includes two guide rods 501. On both sides of the support plate 207 located on one side of the inner shell 201, there are side ears 503 that are sleeved on the surface of the guide rods 501. The side ears 503 and the guide rods 501 are slidably connected. A side ear 502, which is fixedly connected to the shift ring 306, is fixedly installed at the bottom of the guide rods 501. A compression spring 504 is sleeved on the surface of the guide rods 501, and both ends of the compression spring 504 are respectively connected to the side ear 502 and the side ear 503. The guide rod 501 is fixedly connected to the top of the guide rod 501, and a limiting piece 505 is fixedly installed. When using the rubber processing granulation device, the striking element 401 is designed to move longitudinally and simultaneously move its position, allowing it to move around the center of the internal gear 301. This increases the uniformity of the impact of the striking element 401 on the bottom of the screen plate 204, thereby improving the unblocking effect on particles in the screen plate 204. This design ensures the efficiency of particle screening and effectively improves the unblocking efficiency, providing assurance and convenience for the production of rubber raw material particles in the workshop. When using the rubber processing granulation device, the side ear 502, side ear 503, and the compression spring 504 ensure that side ear 503 returns to its initial position and provides a greater striking force to the striking element 401, effectively ensuring the unblocking effect of the striking element 401. When using a particle screening device for rubber processing, the arrangement of the collar 601 and the inclined groove 603, based on the above principle, provides a shielding and protective effect for particle screening, improves the practicality of the mechanism, avoids easy leakage of particles during penetration and movement, and ensures the use of particle screening.

[0042] refer to Figure 1 A support leg 102 is fixedly installed on the outer side of the outer shell 101. A support leg 2 104 is provided at the bottom of the support leg 102. A support spring 103 is fixedly installed between the support leg 102 and the support leg 2 104. A vibration motor 105 is fixedly bolted to the surface of the outer shell 101. The operation of the vibration motor 105 will cause the outer shell 101 to generate a vibration amplitude. The support spring 103 cooperates with the support leg 102 and the support leg 2 104 to provide support and prevent the vibration amplitude from being transmitted to the support leg 2 104, so as to avoid the instability of the support leg 2 104.

[0043] refer to Figure 8 , Figure 9 , Figure 10The striking assembly 4 includes a striking element 401 located inside the inner shell 201. A connecting rod 402, which extends through to the outside of the inner shell 201, is fixedly installed on one side of the striking element 401. An annular groove 406 is provided inside the inner shell 201 to cooperate with the connecting rod 402. The striking element 401 strikes the bottom of the screen plate 204, thereby promoting the smooth discharge of particles stuck in the aperture of the screen plate 204. The annular groove 406, while cooperating with the connecting rod 402 to penetrate the inner shell 201, also ensures the circular movement of the connecting rod 402.

[0044] refer to Figure 6 , Figure 8 , Figure 9 The outer side of the first connecting rod 402 is rotatably connected to the first mounting block 404 via a rotating shaft. The second connecting rod 403 is fixedly mounted on one end of the first connecting rod 402. The second mounting block 405 is rotatably connected to one end of the second connecting rod 403 via a rotating shaft. The second mounting block 405 is fixedly connected to the shifting ring 306. The second mounting block 405 facilitates the angle adjustment between the second connecting rod 403 and the shifting ring 306. When the shifting ring 306 moves longitudinally, it will cause a change in height between one end of the first connecting rod 402 and the striking component 401 through the lever principle. The first mounting block 404 works with the first connecting rod 402 to adjust the angle. The angle between one end of the first connecting rod 402 and the striking component 401 will be adjusted with the first mounting block 404 as the center.

[0045] refer to Figure 12 , Figure 13 , Figure 14 The shielding component 6 includes a collar 601, which is sleeved on the surface of the inner shell 201. A fitting block 602, which is sleeved on the surface of the connecting rod 402, is embedded in the inner side of the collar 601. The fitting block 602 and the mounting block 404 are fixedly connected to each other. A beveled groove 603 is formed on the surface of the collar 601 and located on one side of the fitting block 602. The beveled groove 603 is used in conjunction with the connecting rod 402. Slider blocks 604 are fixedly installed on the surface of the inner shell 201 at the top and bottom of the annular groove 406. A matching slider is formed on the inner side of the collar 601. The sliding groove 605 used for sliding the second slider 604, and the collar 601 will move and be guided on the surface of the inner shell 201 through the setting of the second slider 604 and the second sliding groove 605. When the moving ring 306 moves in a circle, the first connecting rod 402 will simultaneously drive the mating block 602 sleeved on its surface to move. The mating block 602 will also drive the collar 601 to rotate on the surface of the inner shell 201. The setting of the inclined groove 603 will ensure sufficient space for the first connecting rod 402 to adjust the angle, which will facilitate the use of the first connecting rod 402.

[0046] Brief description of operation: When using the rubber granulation device, the operator first feeds the raw rubber particles into the feed pipe 202. The rubber particles are then fed into the inner shell 201 and fall onto the screen plate 204. The operation of the vibrating motor 105 causes the outer shell 101 to vibrate. The support spring 103, in conjunction with the first support leg 102 and the second support leg 104, provides support and prevents the vibration amplitude from being transmitted to the second support leg 104, thus avoiding instability. This vibration amplitude effectively improves the granulation effect of the screen plate 204. Particles of the correct size pass through the aperture of the screen plate 204 to the bottom of the screen plate 204, while particles that do not meet the size requirements remain at the top of the screen plate 204 and are discharged through the vibration amplitude to the discharge frame 2011. When particles become stuck or blocked, the operation of the motor 304 drives the rod 303 and the external gear 302 to rotate. The internal gear 301 remains stationary, while the external gear 302, while rotating, meshes with the internal gear 301, causing it to rotate around the center of the internal gear 301. Simultaneously, the rotation of the rod 303 drives the shaft 305 to rotate. Through the engagement of the inclined groove 307 and vertical groove 308 with the locking member 309, the shifting ring 306 moves longitudinally. When the shifting ring 306 moves the second side ear 503, a positional change occurs between the first and second side ears 502, extending the contraction spring 504. During subsequent contraction, the second side ear 503 returns to its initial position for the next use. When the inclined groove 307 engages with the snap-fit ​​component 309, the shifting ring 306 will slowly return to its starting position. However, when the snap-fit ​​component 309 engages with the vertical groove 308, the shifting ring 306 will rapidly strike the screen plate 204 under the action of the compression spring 504. This design simultaneously enables the longitudinal striking motion of the striking component 401 and allows for positional movement of the striking component 401, causing it to move around the center of the internal gear 301. This increases the uniformity of the striking impact on the bottom of the screen plate 204, thereby improving the unblocking effect on particles in the screen plate 204. This design ensures efficient particle screening and effectively improves the unblocking efficiency, providing assurance and convenience for the production of rubber raw material particles in the workshop. Furthermore, the arrangement of side lug 1 502, side lug 2 503, and the compression spring 504 ensures that side lug 2 503 returns to its initial position, facilitating a greater striking force on the striking component 401 and effectively guaranteeing its impact and unblocking effect. Simultaneously, in the arrangement of the collar 601, when the connecting rod 1 402 moves in a circular motion on the receiving ring 306, the connecting rod 1 402 will synchronously drive the mating block 602 fitted on its surface to move, and the mating block 602 will also drive the collar 601 to rotate on the surface of the inner shell 201.The collar 601 is guided to move on the surface of the inner shell 201 by the sliding block 604 and the sliding groove 605. The inclined groove 603 ensures sufficient space for the connecting rod 402 to adjust its angle. This setting, based on the above principle, provides a shielding and protective effect for particle screening, improves the practicality of the mechanism, avoids easy leakage of particles during penetration and movement, and ensures the use of particle screening.
