[0002] In the production of latex powder, the treatment of powder agglomerates after emulsion drying is crucial. Current screening equipment has many drawbacks, significantly limiting production efficiency and product quality.

[0003] On the one hand, existing vibrating screens have small processing capacity and low efficiency. With the increasing demand for latex powder and the continuous expansion of production scale, screens with small processing capacity cannot keep up with the pace of large-scale production, leading to longer production cycles and increased production costs. On the other hand, dried latex powder is prone to forming agglomerates, and existing equipment lacks effective agglomerate breaking capabilities. This allows these agglomerates to directly enter the finished product, affecting the dispersibility and performance of the latex powder, reducing product quality, and making it difficult to meet the requirements of downstream customers.

[0012] As a further technical solution, the dispersing component includes a pair of fixing plates, both of which are fixed to the surface of the top cover. A drive shaft is rotatably connected inside the fixing plate, and a second motor is provided on the surface of one of the fixing plates.

[0013] As a further technical solution, the output end of the second motor is connected to the drive shaft, and each drive shaft is provided with a drive wheel, which is connected to each other by a belt drive.

[0014] As a further technical solution, a pair of movable rods are movably connected to both ends of the top cover surface, a horizontal plate is provided at the upper end of the movable rod, and a cam is provided at one end of the transmission shaft.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. The beneficial effects of the rotary vibrating screen assembly in this disclosure are as follows: the annular slide rail provides a stable track for the rotating frame, enabling it to rotate smoothly and drive the screen bucket to achieve circumferential motion screening; the buffer spring effectively buffers and reduces shock, ensuring stable operation of the screen bucket and reducing equipment wear; the vibrating motor and the drive motor work together to enhance the screening effect, increase the throughput and screening efficiency; and the polygonal structure of the transmission shaft sleeve and drive shaft ensures stable transmission, avoids slippage, and ensures normal operation of the equipment.

[0021] 2. In this disclosure, the beneficial effect of the dispersing component is that the second motor drives the transmission shaft to rotate synchronously through the transmission wheel and belt, which drives the cam to rotate. The cam pushes the horizontal plate and the movable rod to move up and down. With the buffer reset of the second spring, the pressing frame can crush the agglomerates in a regular manner. This design effectively solves the problem of agglomerates being difficult to break, and improves the dispersibility and product quality of latex powder. Attached Figure Description

[0034] like Figures 1-4 The image shows a vibrating sieve for separating powder agglomerates after emulsion drying in latex powder production, according to an embodiment of this disclosure, comprising:

[0035] An outer cover 1 and an inner cover 2, with the inner cover 2 disposed inside the outer cover 1;

[0036] Top cover 3 and rotary vibrating screen assembly 4, the top cover 3 is installed on the top of the outer cover 1, and the rotary vibrating screen assembly 4 is arranged between the outer cover 1 and the inner cover 2;

[0037] Disintegration component 5 is installed on top cover 3;

[0038] The rotary vibrating screen assembly 4 includes an annular slide rail 4-1, which is arranged around the outer surface of the outer cover 1. A rotating frame 4-2 is slidably connected to the annular slide rail 4-1. Several buffer springs 4-3 are provided on the upper end of the rotating frame 4-2. A bracket 4-4 is connected to the upper end of the buffer springs 4-3. A sleeve 4-5 is connected to the bottom of the bracket 4-4. A screen plate 4-6 is fixed inside the inner cover 2. A pair of vibrating motors 4-7 are installed on the rotating frame 4-2. The inner cover 2 and the sleeve 4-5 are fixedly connected by bolts. A central cover 4-8 is provided at the bottom of the inner cover 2. A transmission sleeve 4-9 is provided on the inner bottom surface of the screen plate 4-6. A drive motor 4-10 is installed on the top cover 3. A drive shaft 4-11 is provided at the output end of the drive motor 4-10. The lower end of the drive shaft 4-11 is inserted into the transmission sleeve 4-9.

[0039] In some examples, during material screening, to achieve efficient screening, a rotary vibrating screen assembly 4 is designed for screening by rotation. This assembly includes an annular slide rail 4-1 arranged around the outer surface of the outer cover 1, providing a stable track and support for the sliding of the rotating frame 4-2. The rotating frame 4-2, slidably connected to the annular slide rail 4-1, can move in a circular motion along the annular slide rail 4-1. Several buffer springs 4-3 are set on the upper end face of the rotating frame 4-2, which play a role in buffering and shock absorption. When the rotating frame 4-2 vibrates during movement, the buffer springs 4-3 can absorb some of the vibration energy, reducing the impact of vibration on the bracket 4-4 and other components. At the same time, it can also keep the bracket 4-4 in a relatively stable state to a certain extent. The bracket 4-4 connected to the upper end of the buffer springs 4-3 is used to support the sleeve 4-5 and the inner cover 2. The sleeve 4-5 is connected to the bottom of the bracket 4-4. The inner cover 2 contains... The inner cover 2 is fixedly connected to the frame 4-5 with a screen plate 4-6, ensuring the stability and firmness of the inner cover 2 during operation. The inner cover 2 and the screen plate 4-6 are the core components for material screening. The transmission sleeve 4-9 on the surface of the screen plate 4-6 inside the inner cover 2 cooperates with the drive shaft 4-11 at the output end of the drive motor 4-10 installed on the top cover 3. The inner diameter of the transmission sleeve 4-9 is larger than the connection of the drive shaft 4-11, leaving room for vibration. When the drive motor 4-10 starts, the drive shaft 4-11 rotates and inserts into the transmission sleeve 4-9, driving the screen plate 4-6 to rotate, thereby realizing screening. A pair of vibrating motors 4-7 installed on the rotating frame 4-2 provide additional vibration effect for the screen plate 4-6. While the screen plate 4-6 rotates, the vibration generated by the vibrating motors 4-7 allows the material in the inner cover 2 to come into more full contact with the screen plate 4-6, improving the screening efficiency.

[0040] like Figures 1-4 As shown, this embodiment proposes a dispersing component 5 including a pair of fixing plates 5-1, both of which are fixed to the surface of the top cover 3. A transmission shaft 5-2 is rotatably connected inside the fixing plate 5-1. A second motor 5-3 is provided on the surface of one of the fixing plates 5-1. The output end of the second motor 5-3 is connected to the transmission shaft 5-2. A transmission wheel 5-4 is provided on each of the transmission shafts 5-2. The transmission wheels 5-4 are connected to each other by belt drive. A pair of movable rods 5-5 are movably fitted to both ends of the surface of the top cover 3. A horizontal plate 5-6 is provided at the upper end of the movable rod 5-5. A cam 5-7 is provided at one end of the transmission shaft 5-2. The cam 5-7 slides and fits against the surface of the horizontal plate 5-6. A second spring 5-8 is fitted on the movable rod 5-5. A pressing frame 5-9 is provided at the lower end of the movable rod 5-5.

[0041] In some examples, during the powder processing after emulsion drying, the powder agglomerates formed after drying need to be crushed first in order to facilitate sieving. For this purpose, a dispersing component 5 is designed. This component includes a pair of fixed plates 5-1 fixed to the surface of the top cover 3. A drive shaft 5-2 is rotatably connected within the fixed plates 5-1 and can rotate under the drive of a second motor 5-3. The second motor 5-3, located on the surface of one of the fixed plates 5-1, has its output end connected to the drive shaft 5-2, serving as the power source for the entire component. After starting, the second motor 5-3 drives the drive shaft 5-2 to rotate at high speed. Each drive shaft 5-2 is equipped with a drive wheel 5-4, which are connected by a belt drive. This transmission method allows the two drive shafts 5-2 to rotate synchronously. The top cover 3 has a pair of movable rods 5-5 that are movably connected to both ends. The movable rods 5-5 can move up and down linearly on the surface of the top cover 3. The horizontal plate 5-6 set at the upper end of the movable rod 5-5 interacts with the cam 5-7 set at one end of the drive shaft 5-2. When the drive shaft 5-2 rotates, the cam 5-7 rotates accordingly. Due to the special shape of the cam 5-7, it will continuously push the horizontal plate 5-6 to move up and down during the sliding contact process with the surface of the horizontal plate 5-6. The second spring 5-8 set on the movable rod 5-5 plays a role in buffering and resetting during the operation of the component. The pressing frame 5-9 set at the lower end of the movable rod 5-5 performs regular pressing and crushing operations on the powder agglomerates after the emulsion is dried as the movable rod 5-5 moves up and down.

[0042] For example, such as Figure 1 As shown, the top of the outer cover 1 is rotatably connected to the limit frame 6, and the bottom surface of the limit frame 6 is in contact with the surface of the top cover 3.

[0043] In some examples, the limiting bracket 6 increases the fixing effect on the outer cover 1, preventing the outer cover 1 from being lifted when subjected to reverse thrust.

[0044] For example, such as Figure 3 As shown, the cross-section of the transmission connection between the transmission sleeve 4-9 and the drive shaft 4-11 is polygonal.

[0045] In some examples, the polygonal structure prevents the drive shaft 4-11 from slipping when it drives the transmission sleeve 4-9 to rotate.

[0046] For example, such as Figure 3 As shown, the cross-section of the connection between the top cover 3 and the outer cover 1 is a stepped structure, and the connection between the top cover 3 and the outer cover 1 is a limiting insert connection.

[0047] In some examples, the top cover 3 is embedded inside the outer cover 1 through a stepped structure, and the connection method is plug-in, so there is no rotation.

[0048] In actual use: Pour the latex powder agglomerates to be screened into the sieve plate 4-6, start the drive motor 4-10, and drive the drive shaft 4-11 to drive the sieve plate 4-6 to rotate under the action of the rotating vibrating sieve assembly 4. At the same time, start the vibration motor 4-7 on the rotating frame 4-2 to make the sieve plate 4-6 vibrate on the basis of rotation, which promotes screening. Start the second motor 5-3 of the dispersing assembly 5, which drives the drive shaft 5-2 to rotate through the transmission wheel 5-4 and belt. The cam 5-7 pushes the horizontal plate 5-6 and the movable rod 5-5 to move up and down. The pressing frame 5-9 crushes the agglomerates. The screened latex powder is collected and discharged through the collection cover 4-8 at the bottom of the sieve plate 4-6.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
