Description

Technical Field

[0001] This utility model relates to the field of rubber compound production technology, and in particular to a device for ensuring uniform mixing of novel additives in rubber compounds. Background Technology

[0002] Rubber compound is a homogeneous mixture of raw rubber and compounding agents. Adding various additives to improve the performance of rubber compound is a common practice during its production. The use of novel additives is becoming increasingly widespread; however, due to the differences in physical and chemical properties between novel and traditional additives, existing mixing equipment often struggles to achieve uniform mixing when incorporating them. Uneven mixing leads to unstable rubber compound performance, affecting product quality and consistency. Currently, most related mixing devices employ a single stirring method, which is ineffective in dispersing novel additives and cannot meet the production requirements of high-quality rubber compound. Therefore, we propose a device to ensure uniform mixing of novel additives in rubber compound to solve the aforementioned problems. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing a device for ensuring uniform mixing of novel additives in rubber compound.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An apparatus for ensuring uniform mixing of novel additives in rubber compound includes a mixing tank. A feed pipe for adding the novel additives is fixedly connected to the top of the mixing tank. A cover is fixedly connected to the top of the mixing tank. A lifting plate is slidably disposed within the cover. A reciprocating lifting mechanism is provided between the mixing tank, the lifting plate, and the cover. A stirring and dispersing mechanism for uniformly mixing the novel additives in the rubber compound is provided between the lifting plate and the mixing tank. The stirring and dispersing mechanism includes a stirring shaft rotatably disposed at the bottom of the lifting plate. Three support legs are fixedly connected to the bottom of the mixing tank. A discharge pipe is fixedly connected to the bottom of the mixing tank.

[0006] As a preferred embodiment of this utility model, the reciprocating lifting mechanism includes a drive motor fixedly connected to the top of the lifting plate and two vertical springs fixedly connected to the top of the mixing tank. A rotating shaft is fixedly connected to the output shaft of the drive motor. Two cams are fixedly sleeved on the outer side of the rotating shaft. The two cams cooperate with the inner wall of the top of the cover. The top ends of the two vertical springs are fixedly connected to the bottom of the lifting plate.

[0007] As a preferred embodiment of this utility model, a support plate is fixedly connected to the top of the lifting plate, a bearing is fixedly connected to one side of the support plate, and the rotating shaft is fixedly sleeved inside the inner ring of the bearing.

[0008] In a preferred embodiment of this invention, a fixed base is fixedly connected to the top of the lifting plate, and the drive motor is fixedly connected to the top of the fixed base.

[0009] As a preferred embodiment of this invention, a sealing sleeve is fixedly connected to the top of the mixing tank, and the stirring shaft is movably sleeved inside the sealing sleeve.

[0010] As a preferred embodiment of this utility model, two telescopic rods are fixedly connected between the mixing tank and the lifting plate, and two vertical springs are respectively sleeved on the outside of the corresponding telescopic rods.

[0011] In a preferred embodiment of this invention, the stirring and dispersing mechanism includes a driving bevel gear fixedly sleeved on the outside of the rotating shaft and a driven bevel gear fixedly connected to the top of the stirring shaft. The driving bevel gear and the driven bevel gear mesh with each other. Three dispersing discs are fixedly sleeved on the outside of the stirring shaft. Several dispersing needles are fixedly connected to the top of the dispersing discs, and several stirring rods are fixedly connected to the bottom of the lower dispersing discs. Two stirring paddles are fixedly connected to both sides of the stirring shaft, and the same arc-shaped stirring blade is fixedly connected to one end of each stirring paddle.

[0012] As a preferred embodiment of this invention, several flow-disrupting plates are fixedly connected to the inner wall of the mixing tank, and the flow-disrupting plates are distributed in an inclined manner.

[0013] In this invention, the device for ensuring uniform mixing of novel additives in rubber compound is described. A drive motor drives the rotation of a rotating shaft and a driving bevel gear. The driving bevel gear drives the rotation of a driven bevel gear and a stirring shaft. The stirring shaft drives the rotation of a dispersing disc and a dispersing needle. The dispersing needle on the dispersing disc performs high-speed cutting and dispersing of the material, ensuring that the novel additives are more uniformly dispersed in the rubber compound. Simultaneously, the drive rotates the stirring rod, stirring paddle, and arc-shaped stirring blade, achieving efficient mixing. The baffles on the inner wall of the mixing tank can change the flow direction of the material, increasing collision and friction between materials, further improving the mixing effect, enhancing the uniformity of the novel additives in the rubber compound, and ensuring the stability of the rubber compound's performance.

[0014] In this invention, a device for ensuring uniform mixing of a novel additive in a rubber compound is described. Simultaneously, the rotating shaft drives the synchronous rotation of two cams. When the cam rotates upwards to abut against the inner wall of the top of the enclosure, it causes the lifting plate and stirring shaft to move downwards, while the vertical spring is compressed. When the cam rotates downwards and no longer abuts against the inner wall of the top of the enclosure, the lifting plate and stirring shaft move upwards to reset under the elastic force of the vertical spring, thereby driving the reciprocating lifting and lowering of the dispersing disc. This causes the material to tumble up and down, and simultaneously drives the reciprocating lifting and lowering of the stirring rod, stirring paddle, and arc-shaped stirring blade, increasing the mixing area and making the mixing more uniform, comprehensive, and thorough, resulting in a more complete mixture.

[0015] This utility model has a reasonable structural design, which can realize the dual mixing and dispersion of the compound and the new additive, improve the uniformity of the new additive in the compound, ensure the stability of the compound performance, and further improve the mixing effect by increasing the collision and friction between materials through the baffle, making the mixing more thorough. It also drives the reciprocating lifting and lowering of the dispersing disc, stirring rod, stirring paddle and arc-shaped stirring blade, which can tumble the materials up and down and increase the mixing area, making the mixing more uniform, comprehensive and thorough.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4An apparatus for ensuring uniform mixing of novel additives in rubber compound includes a mixing tank 1. The top of the mixing tank 1 is fixedly connected to a feed pipe 3 for adding the novel additives. The top of the mixing tank 1 is fixedly connected to a cover 2. A lifting plate 7 is slidably arranged inside the cover 2. A reciprocating lifting mechanism 6 is arranged between the mixing tank 1, the lifting plate 7 and the cover 2. A stirring and dispersing mechanism 9 for uniformly mixing the novel additives in the rubber compound is arranged between the lifting plate 7 and the mixing tank 1. The stirring and dispersing mechanism 9 includes a stirring shaft 93 rotatably arranged at the bottom of the lifting plate 7. Three support legs 5 are fixedly connected to the bottom of the mixing tank 1. A discharge pipe 4 is fixedly connected to the bottom of the mixing tank 1.

[0023] Furthermore, refer to Figures 2-4 The reciprocating lifting mechanism 6 includes a drive motor 61 fixedly connected to the top of the lifting plate 7 and two vertical springs 67 fixedly connected to the top of the mixing tank 1. A rotating shaft 63 is fixedly connected to the output shaft of the drive motor 61. Two cams 62 are fixedly sleeved on the outer side of the rotating shaft 63. The two cams 62 cooperate with the top inner wall of the cover 2. The top ends of the two vertical springs 67 are fixedly connected to the bottom of the lifting plate 7.

[0024] Using the above scheme: the rotation of the rotating shaft 63 drives the synchronous rotation of the two cams 62. When the cams 62 rotate upward and abut against the inner wall of the top of the cover 2, they will drive the lifting plate 7 and the stirring shaft 93 to move downward. At the same time, the vertical spring 67 is compressed. When the cams 62 rotate downward and do not abut against the inner wall of the top of the cover 2, the lifting plate 7 and the stirring shaft 93 will move upward and reset under the elastic force of the vertical spring 67. This drives the reciprocating lifting and lowering of the dispersing disc 94, which in turn drives the material to tumble up and down. At the same time, it drives the reciprocating lifting and lowering of the stirring rod 96, the stirring paddle 97 and the arc-shaped stirring plate 98, which can increase the stirring area, making the mixing more uniform, comprehensive and thorough, and making the mixing more complete.

[0025] Furthermore, a support plate 65 is fixedly connected to the top of the lifting plate 7, and a bearing 64 is fixedly connected to one side of the support plate 65. The rotating shaft 63 is fixedly sleeved in the inner ring of the bearing 64, which can support the rotating shaft 63 and make its rotation more stable.

[0026] Furthermore, a fixed base 69 is fixedly connected to the top of the lifting plate 7, and the drive motor 61 is fixedly connected to the top of the fixed base 69, which facilitates fixing the drive motor 61 to the top of the lifting plate 7.

[0027] Furthermore, a sealing sleeve 68 is fixedly connected to the top of the mixing tank 1, and the stirring shaft 93 is movably sleeved inside the sealing sleeve 68, which facilitates the guiding and limiting of the stirring shaft 93, making its movement more stable.

[0028] Furthermore, two telescopic rods 66 are fixedly connected between the mixing tank 1 and the lifting plate 7, and two vertical springs 67 are respectively sleeved on the outside of the corresponding telescopic rods 66, which can guide the lifting plate 7 and the vertical springs 67 to make its lifting more stable.

[0029] Furthermore, refer to Figures 2-4 The stirring and dispersing mechanism 9 includes a driving bevel gear 92 fixedly sleeved on the outside of the rotating shaft 63 and a driven bevel gear 91 fixedly connected to the top of the stirring shaft 93. The driving bevel gear 92 and the driven bevel gear 91 mesh with each other. Three dispersing discs 94 are fixedly sleeved on the outside of the stirring shaft 93. Several dispersing needles 95 are fixedly connected to the top of the dispersing discs 94. Several stirring rods 96 are fixedly connected to the bottom of the lower dispersing discs 94. Two stirring paddles 97 are fixedly connected to both sides of the stirring shaft 93. One end of the two stirring paddles 97 is fixedly connected to the same arc-shaped stirring blade 98.

[0030] The above scheme is adopted: the drive motor 61 drives the rotation of the rotating shaft 63 and the active bevel gear 92, the active bevel gear 92 drives the rotation of the driven bevel gear 91 and the stirring shaft 93, the stirring shaft 93 drives the rotation of the dispersing disk 94 and the dispersing needle 95, the dispersing needle 95 on the dispersing disk 94 cuts and disperses the material at high speed, so that the new additive is more evenly dispersed in the compound. At the same time, it drives the rotation of the stirring rod 96, the stirring paddle 97 and the arc-shaped stirring plate 98 to achieve efficient stirring and mixing.

[0031] Furthermore, several flow-disrupting plates 8 are fixedly connected to the inner wall of the mixing tank 1. The flow-disrupting plates 8 are distributed in an inclined manner. The flow-disrupting plates 8 on the inner wall of the mixing tank 1 can change the flow direction of the material, increase the collision and friction between the materials, further improve the mixing effect, improve the uniformity of the new additive in the compound, and ensure the stability of the compound's performance.

[0032] In this invention, during use, the drive motor 61 drives the rotating shaft 63 and the driving bevel gear 92 to rotate. The driving bevel gear 92 drives the driven bevel gear 91 and the stirring shaft 93 to rotate. The stirring shaft 93 drives the dispersing disc 94 and the dispersing needles 95 to rotate. The dispersing needles 95 on the dispersing disc 94 perform high-speed cutting and dispersing of the material, making the new additive more evenly dispersed in the compound. At the same time, the drive drives the rotation of the stirring rod 96, the stirring paddle 97 and the arc-shaped stirring blade 98 to achieve efficient mixing. The baffle 8 on the inner wall of the mixing tank 1 can change the flow direction of the material, increase the collision and friction between the materials, further improve the mixing effect, and improve the uniformity of the new additive in the compound. This ensures the stability of the compound's properties. Simultaneously, the rotation of the shaft 63 drives the synchronous rotation of two cams 62. When the cams 62 rotate upwards and abut against the inner top wall of the cover 2, they cause the lifting plate 7 and stirring shaft 93 to move downwards, compressing the vertical spring 67. When the cams 62 rotate downwards and no longer abut against the inner top wall of the cover 2, the lifting plate 7 and stirring shaft 93 will move upwards and reset under the elastic force of the vertical spring 67, thereby driving the reciprocating lifting and lowering of the dispersing disc 94. This causes the material to tumble up and down, simultaneously driving the reciprocating lifting and lowering of the stirring rod 96, stirring paddle 97, and arc-shaped stirring blade 98, increasing the mixing area and making the mixing more uniform, comprehensive, and thorough.
