[0002] Rubber is a very important industrial raw material, which is widely used in fields such as tires and industrial products. During the rubber processing, it is often necessary to make large pieces of raw materials into granular materials, which is called the granulation process of rubber.
[0003] Commodities made of rubber are becoming more and more popular in modern life. Therefore, in the production of existing products, the specifications of rubber raw materials are relatively strict. However, the screening devices in the existing technology generally use screening plates with different sizes of filtering holes for fine screening. But such a screening method is extremely easy to cause granular raw materials of different sizes and specifications to be mixed together, and it is also extremely easy to cause the blockage of the filtering holes, which will then cause the accumulation inside the screening device, making it very difficult to carry out normal fine screening.
[0004] Therefore, to solve these problems, we need a granulating device for rubber preparation. Summary of the Invention

[0032] Inside the body 1, there is a blanking anti-blocking mechanism 5. Outside the body 1, there is a collecting pipe 6 which is used to transfer the modified rubber raw material particles after being screened by the screening and blanking mechanism 8 out of the inside of the body 1. Inside the body 1, there is a blowing mechanism 7 and an auxiliary blanking mechanism 9. The auxiliary blanking mechanism 9 is connected to the outside of the screening and blanking mechanism 8; The blanking anti-blocking mechanism 5 includes a main blanking port 51, a secondary blanking port 52, a motor 53, a rotating wheel 54, a spiral turntable 55, an arc rod 56, a blanking plate 57, blanking holes 58, and a sponge ring 59.

There are two secondary blanking ports 52, and the main blanking port 51 is located between the two secondary blanking ports 52. The motor 53 is fixedly connected to the bottom of the partition plate 4. The bottom of the rotating wheel 54 is connected to the motor 53. The top of the rotating wheel 54 is fixedly connected with a spiral turntable 55. There are more than or equal to 3 arc rods 56 fixedly connected to the outside of the rotating wheel 54 at equal angles. The blanking plate 57 is arranged between the body 1 and the partition plate 4. The blanking plate 57 is in an inverted conical shape, and a plurality of uniformly distributed blanking holes 58 are opened on the surface of the blanking plate 57. The sponge ring 59 is arranged between the body 1 and the partition plate 4, and the sponge ring 59 is fixedly connected to the inner wall of the body 1; The blowing mechanism 7 includes a blower 71 and a baffle 72. The blower 71 is fixedly connected to the body 1. The blower 71 is located above the collecting pipe 6. The baffle 72 is located between the blower 71 and the collecting pipe 6, and the baffle 72 is fixedly connected to the inner wall of the body 1; The auxiliary blanking mechanism 9 includes a curved rod 91, a piston 92, a curved sleeve 93, and an air pipe 94. The curved rod 91 is fixedly connected to the top of the carrier plate 81. The curved rod 91 is located between the electric telescopic rod 82 and the body 1. The top of the curved rod 91 is fixedly connected with a piston 92. The curved sleeve 93 is fixedly connected to the bottom of the first screening plate 85.

[0033] Working principle: When the motor 53 is powered on and starts, it drives the rotating wheel 54 to rotate. The rotation of the rotating wheel 54 drives the spiral turntable 55 and the arc rod 56 to rotate. The rotation of the arc rod 56 drives the movement of the initial rubber raw material particles. The rubber raw material particles that conform to the aperture of the feeding hole 58 will pass through the feeding hole 58, and the rubber raw material particles passing through the feeding hole 58 will move downward through the main feeding port 51 and the secondary feeding port 52; the electric telescopic rod 82 is powered on to perform vertical telescopic movement, and it will drive the movable shaft 83 to reciprocate inside the chute 84, and then the first screening plate 85 will perform a small-amplitude reciprocating rotation. The reciprocating rotation of the first screening plate 85 drives the second screening plate 88 to reciprocate. The reciprocating rotation of the second screening plate 88 drives the roller 811 to roll outside the arc plate 812. Restricted by the arc plate 812, the second screening plate 88 will be pressed into the inside of the first screening plate 85 and compress the spring 810. Under the elastic force of the spring 810, the second screening plate 88 will also reciprocate inside the first screening plate 85. In this way, the misaligned movement of the second screening plate 88 and the first screening plate 85 will cause the upper holes 86, the lower holes 87, and the middle holes 89 to intermittently coincide. When the rubber raw material particles pass through the screening and feeding mechanism 8, they will move downward and enter the next screening and feeding mechanism 8. At the same time, the reciprocating movement of the first screening plate 85 will drive the curved sleeve 93 to reciprocate. The reciprocating movement of the curved sleeve 93 is squeezed by the piston 92, and the air inside the curved sleeve 93 will be blown out through the air pipe 94 and the branch pipe.
[0034] During specific use, a rubber preparation granulation device provided by the present invention adopts a feeding anti-blocking mechanism 5, a blowing mechanism 7, a screening and feeding mechanism 8, an auxiliary feeding mechanism 9, etc.; it solves the problem that the screening method using filtering holes of different sizes for fine separation is extremely likely to cause the mixing of modified rubber raw material particles of different sizes and specifications, and thus is extremely likely to cause blockage of the filtering holes. This device can not only solve the problem of particle blockage during feeding, but also can accurately separate modified rubber raw material particles of different sizes and specifications, and there will be no blockage during the screening process, enabling this device to achieve the effect of multi-stage screening, and such screening speed will be faster.
[0035] Please refer to Figure 1 、 5, 6, the blanking anti-blocking mechanism 5 includes a main blanking port 51, a secondary blanking port 52, a motor 53, a rotating wheel 54, a spiral turntable 55, an arc rod 56, a blanking plate 57, blanking holes 58, and a sponge ring 59. The main blanking port 51 and the secondary blanking port 52 are both opened on the surface of the partition plate 4. There are two secondary blanking ports 52, and the main blanking port 51 is located between the two secondary blanking ports 52. The motor 53 is fixedly connected to the bottom of the partition plate 4. The bottom of the rotating wheel 54 is connected to the motor 53. The top of the rotating wheel 54 is fixedly connected to a spiral turntable 55. There are more than or equal to 3 arc rods 56 fixedly connected to the outside of the rotating wheel 54 at equal angles. The blanking plate 57 is arranged between the machine body 1 and the partition plate 4. The blanking plate 57 is in an inverted conical shape, and a plurality of uniformly distributed blanking holes 58 are opened on the surface of the blanking plate 57. The sponge ring 59 is arranged between the machine body 1 and the partition plate 4. The sponge ring 59 is fixedly connected to the inner wall of the machine body 1; the blowing mechanism 7 includes a blower 71 and a baffle 72. The blower 71 is fixedly connected to the machine body 1. The blower 71 is located above the collection pipe 6. The baffle 72 is located between the blower 71 and the collection pipe 6. The baffle 72 is fixedly connected to the inner wall of the machine body 1.
[0036] When the motor 53 is powered on and starts, it will drive the rotating wheel 54 to rotate. The rotation of the rotating wheel 54 drives the spiral turntable 55 and the arc rod 56 to rotate. The rotation of the arc rod 56 drives the initial rubber raw material particles to move. The rubber raw material particles that meet the aperture of the blanking hole 58 will pass through the blanking hole 58. The rubber raw material particles passing through the blanking hole 58 will move downward through the main blanking port 51 and the secondary blanking port 52; although the inverted conical blanking plate 57 can facilitate the entry of a large number of rubber raw material particles, it is also relatively easy to cause blockage. Therefore, the spiral turntable 55 can transport the rubber raw material particles at the lower part to the upper part, avoiding blockage and affecting the operation of the motor 53. And there is an arc rod 56, which can use centrifugal force to transport the rubber raw material particles to the blanking holes 58 at different heights. The setting of the blanking holes 58 can prevent the agglomerated rubber raw material particles from entering the subsequent screening and sizing, ensuring the quality of the modified rubber raw material particles. The sponge ring 59 can prevent the rubber raw material particles from hitting the machine body 1 and making a large noise. The blower 71 can not only prevent the falling rubber raw material particles from entering the collection pipe 6, but also dry the falling rubber raw material particles. The baffle 72 can also block the rubber raw material particles from entering the collection pipe 6, thus ensuring the screening quality of different specifications.

The barrier cloth 814 is wound around the outside of the tightening wheel 813; the screening and feeding mechanism 8 further includes a carrier plate 81, an electric telescopic rod 82, a movable shaft 83, and a chute 84. The carrier plate 81 is fixedly connected to the inner wall of the machine body 1. The electric telescopic rod 82 is fixedly connected to the top of the carrier plate 81. The movable shaft 83 is rotatably connected to the outside of the electric telescopic rod 82. There are two chutes 84 and they are symmetrically and fixedly connected to the bottom of the first screening plate 85. The two ends of the movable shaft 83 are respectively rollingly connected to the inside of the two chutes 84; the number of the upper holes 86, lower holes 87, and middle holes 89 is the same. There are multiple upper holes 86, lower holes 87, and middle holes 89. And multiple upper holes 86 are evenly distributed on the upper surface of the first screening plate 85. Multiple lower holes 87 are evenly distributed on the lower surface of the first screening plate 85. Multiple middle holes 89 are evenly distributed on the surface of the second screening plate 88. The apertures of the upper holes 86, lower holes 87, and middle holes 89 are the same. Two rollers 811 are symmetrically arranged outside one second screening plate 88. The rollers 811 are rollingly connected to the curved plate 812. The tightening wheel 813 is used to automatically tighten the barrier cloth 814. The barrier cloth 814 is used to block the downward fall of the modified rubber raw material particles. One side of the barrier cloth 814 is fixedly connected to the outside of the tightening wheel 813, and the other side is fixedly connected to the top of the first screening plate 85; the center of the curved plate 812 and the rotation point of the first screening plate 85 are not the same point. In the initial state, the electric telescopic rod 82 is in the power-off and contracted state. When the second screening plate 88 rotates counterclockwise to drive the roller 811 to move, the curved plate 812 will squeeze the second screening plate 88 through the roller 811, thereby causing the second screening plate 88 to slide into the first screening plate 85; there are at least 2 screening and feeding mechanisms 8 arranged in the machine body 1 and they are equidistantly arranged from top to bottom inside the machine body 1. The apertures of the screening and feeding mechanisms 8 gradually decrease from top to bottom;The auxiliary blanking mechanism 9 includes a curved rod 91, a piston 92, a curved sleeve 93, and an air pipe 94. The curved rod 91 is fixedly connected to the top of the carrier plate 81. The curved rod 91 is located between the electric telescopic rod 82 and the machine body 1. The top of the curved rod 91 is fixedly connected with a piston 92. The curved sleeve 93 is fixedly connected to the bottom of the first screening plate 85. The piston 92 is slidably connected inside the curved sleeve 93. The curved rod 91 is slidably connected with the curved sleeve 93. One end of the air pipe 94 is connected to the inside of the curved sleeve 93, and the other end of the air pipe 94 is fixedly connected with a plurality of branch pipes, and the branch pipes are evenly distributed on both sides of the lower hole 87.;
[0038] The screening and blanking mechanism 8 clamps and then relaxes the rubber raw material particles entering the upper hole 86 through the coincidence of different motion states among the upper hole 86, the lower hole 87, and the middle hole 89. Such intermittent clamping can prevent the rubber raw material particles from blocking inside the upper hole 86, the lower hole 87, and the middle hole 89. Moreover, the reciprocating motion of the first screening plate 85 and the second screening plate 88 can also shake the rubber raw material particles on the top of the first screening plate 85, preventing the rubber raw material particles from accumulating on the top of the first screening plate 85, achieving the effect of dispersing the rubber raw material particles. And the barrier cloth 814 can prevent the rubber raw material particles from entering the gap between the first screening plate 85 and the machine body 1 under the automatic tightening action of the tightening wheel 813, ensuring the normal operation of the screening. Moreover, as the first screening plate 85 moves, it can also convey the air inside the curved sleeve 93 to the inside of the lower hole 87, making there intermittent air convection inside the lower hole 87, further preventing the rubber raw material particles from blocking inside the lower hole 87. And multiple screening and blanking mechanisms 8 can realize the screening of rubber raw material particles of multiple different specifications, which is more suitable for use in actual situations.
