[0002] High-speed mixers for plastic granules are essential equipment in plastic processing plants and are also widely used in industries such as rubber, pharmaceuticals, and dyeing. They are characterized by fast mixing, uniform mixtures, good resin absorption of additives, easy operation and cleaning, durability, and compact structure. As a result, they have gradually replaced low-speed mixers and are now widely used in the production of various plastic industries.
[0003] The existing publicly available technology, application number CN202022430281.8, describes a high-speed mixer for plastic granules. It allows for convenient disassembly and assembly of the mixing tank, enabling flexible disassembly and use of the equipment. This facilitates cleaning and maintenance of the tank and also ensures better, more uniform, and efficient mixing after installation, which is beneficial for the equipment's processing operations.
[0004] However, the above-mentioned patent still has certain drawbacks in use: its mixing structure is relatively simple, and when mixing multiple plastic particles, it is easy for particles to stick together or for excessively large particles to be mixed in, resulting in poor mixing uniformity and poor mixing quality, which reduces the overall mixing quality and makes the device less than ideal.
[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0006] (a) Technical problems to be solved
[0007] To address the shortcomings of existing technologies, this invention provides a high-speed mixing device for polymer particles, which has the advantages of good mixing effect, pre-screening before mixing, and cyclic mixing, thereby solving the problems mentioned in the background technology.
[0008] (II) Technical Solution
[0009] To achieve the advantages of good mixing effect, pre-sieving before mixing, and circulating mixing, the specific technical solution adopted by this utility model is as follows:
[0010] A high-speed polymer particle mixing device includes a body and supporting legs. A partition is installed at the top of the interior of the body. Several processing chambers are provided between the partition and the interior of the body. A drive shaft is installed in the middle of the processing chamber. One end of the drive shaft passes through one side of the body and is connected to a first motor. Several dispersing rods are symmetrically installed around both sides of the drive shaft. Scrapers are symmetrically installed in the middle of the drive shaft. Several sets of sieve holes are opened below the drive shaft at the bottom of the partition. Several sets of circulation cylinders are evenly installed at the bottom of the outer surface of the body. Discharge ports and circulation ports are respectively opened at both ends of the circulation cylinders where they are in contact with the surface of the body. A spiral auger is installed inside the circulation cylinder. One end of the spiral auger passes through one side of the circulation cylinder and is connected to a second motor.
[0011] Furthermore, a stirring shaft is installed at the middle of the bottom of the machine body. One end of the stirring shaft passes through one side of the machine body and is connected to a third motor. Several sets of stirring blades are evenly installed on the surface of the stirring shaft.

[0018] (III) Beneficial Effects
[0019] Compared with the prior art, this utility model provides a high-speed mixing device for polymer particles, which has the following beneficial effects:
[0020] This invention employs a processing chamber and a spiral auger. After the plastic granules are added, the dispersing rods and scrapers inside the processing chamber disperse and agitate the granules, allowing any clumps to disperse and move. This enables the granules to be sieved according to their size when they come into contact with the sieve holes, thus blocking excessively large or clumped granules and ensuring a more uniform particle size in the mixture. This improves the overall mixing quality. The sieve holes also allow for the discharge of granules in small, multiple batches, preventing uneven mixing caused by large-volume introduction. Furthermore, the spiral auger can re-discharge granules from the bottom layer to the top during mixing, allowing granules in different positions to make more thorough contact, further enhancing the overall mixing quality. This invention offers advantages such as good mixing effect, pre-screening before mixing, and cyclic mixing. Attached Figure Description

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0029] According to an embodiment of the present invention, a high-speed mixing device for polymer particles is provided.
[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a high-speed polymer particle mixing device according to an embodiment of the present invention includes a body 1 and supporting legs 15. A partition 5 is installed at the top of the interior of the body 1. Several processing chambers 4 are provided between the partition 5 and the interior of the body 1. A drive shaft 3 is installed in the middle of the processing chamber 4. One end of the drive shaft 3 passes through one side of the body 1 and is connected to a first motor 9. Several dispersing rods 6 are symmetrically installed around the two sides of the surface of the drive shaft 3. Scrapers 7 are symmetrically installed in the middle of the surface of the drive shaft 3. Several sets of sieve holes 8 are opened below the drive shaft 3 at the bottom of the partition 5. Several sets of circulation cylinders 12 are evenly installed at the bottom of the outer surface of the body 1. The two ends of the circulation cylinders 12 are attached to the surface of the body 1. The mixing chamber 12 is equipped with a discharge port 11 and a circulation port 14. A spiral auger 13 is installed inside the circulation cylinder 12. One end of the spiral auger 13 passes through one side of the circulation cylinder 12 and is connected to the second motor 10. The spiral auger 13 is designed to circulate the particles, allowing particles at different positions to come into more thorough contact, thereby improving the overall mixing quality and facilitating better use. The lengths of the dispersing rod 6 and the scraper 7 need to be adjusted according to the changes in the internal structure of the processing chamber 4 to avoid impacting the inner wall of the processing chamber 4 during rotation and to avoid affecting the normal operation of the structure. The number of processing chambers 4 can be adjusted according to needs, which will not be elaborated on here.
[0031] In one embodiment, a stirring shaft 18 is installed at the middle of the bottom of the machine body 1. One end of the stirring shaft 18 passes through one side of the machine body 1 and is connected to a third motor 17. Several sets of stirring blades 19 are evenly installed on the surface of the stirring shaft 18. The stirring blades 19 are set to stir and mix the sieved particles.
[0032] In one embodiment, the top of the machine body 1 is provided with a feed inlet 2 at the location of the processing chamber 4. The feed inlet 2 is provided to facilitate the addition of raw materials that need to be mixed, so as to facilitate subsequent mixing operations.
[0033] In one embodiment, several sets of support legs 15 are symmetrically installed on both sides of the bottom of the body 1. The support legs 15 can fix the entire device, thereby enhancing the overall stability of use.
[0034] In one embodiment, discharge ports 16 are symmetrically provided on both sides of the bottom center of the machine body 1. The discharge ports 16 are provided to facilitate the discharge of the mixed particles for subsequent processing. Since the discharge ports 16 and the inlet ports 2 are common features in the machine body 1, the corresponding sealing structures will not be described in detail. Personnel can set them themselves, such as by setting valves or baffles.
[0035] In one embodiment, the discharge port 11 is located above the circulation port 14. The positions of the discharge port 11 and the circulation port 14 are set so that the particles enter from the circulation port 14 and are discharged from the discharge port 11, thereby achieving a complete circulation operation.
[0036] In one embodiment, both the discharge port 11 and the circulation port 14 are provided with ramps. The ramps are designed to facilitate the sliding of the plastic granules that need to be circulated into and out of the circulation cylinder 12, thereby achieving smooth circulation operation, improving the overall mixing quality, and making it easier to use.
[0037] In one embodiment, the height of the support leg 15 is greater than the length of the discharge port 16. The height of the support leg 15 is set to ensure that there is space below the discharge port 16 for a collection device to collect the mixed polymer particles, which is convenient for subsequent collection and use.
[0038] Working Principle: In actual use, personnel can add the required polymer plastic granules to the processing chamber 4 through the feed inlet 2. Then, the operation of the first motor 9 drives the drive shaft 3 to rotate. When the drive shaft 3 rotates, the dispersing rods 6 on its surface impact the plastic granules inside, thereby dispersing any clumps. At the same time, the scraper 7 agitates the plastic granules, causing them to move. This allows the moving plastic granules to come into contact with the sieve holes 8, thus screening the plastic granules according to their size. This ensures that the plastic granules that meet the mixing requirements are successfully screened out, thereby guaranteeing the uniformity of the subsequent mixing. Furthermore, the sieving setting of the sieve hole 8 allows the plastic particles to be discharged in small amounts and multiple times, thus avoiding the phenomenon of large-scale simultaneous falling of plastic particles causing high operating pressure and uneven mixing. The falling plastic particles can then be mixed by the operation of the stirring blades 19 below, improving the overall mixing uniformity. At the same time, during stirring, the bottom plastic particles can be transported to the discharge port 11 through the bottom circulation port 14 via the spiral auger 13 and discharged from the top, so that the plastic particles in different positions can come into more thorough contact, thereby improving the overall mixing quality and facilitating better use. The device as a whole has the advantages of good mixing effect, pre-screening before mixing, and circulating mixing.
