[0002] Plastic particles are the common name of plastic pellets, which are the raw materials for storing, transporting and processing plastic in semi-finished form. They are made by the extrusion granulation process and are generally processed and formed through processes such as raw material mixing, kneading, and extrusion granulation.

[0003] In order to facilitate feeding, the bottom end of the existing plastic particle mixing device is generally funnel-shaped. For example, in the Chinese patent literature database, a plastic particle mixing blender with the application number 201821701190.X is prone to cause uneven mixing of materials at the bottom end and may also have problems of blockage. Summary of the Invention

A plurality of first through holes are arranged in a circular array at the bottom end of the mixing chamber with the center of the mixing chamber as the center of the circle. The bottom end of the mixing chamber is rotatably provided with a baffle for closing and blocking the first through holes through a first rotation driving member, and a plurality of second through holes corresponding to the first through holes one by one are arranged through the baffle. The first rotation driving member drives the baffle to rotate so that the second through holes coincide with or separate from the first through holes.

[0006] Further, a material guiding platform with gradually increasing dimensions from top to bottom is arranged in the middle of the top end of the baffle.

[0007] Further, the first rotation driving member is installed at the bottom end inside the mixing chamber, and the first rotation driving member is located inside the material guiding platform.

A storage tank is movably placed below the sealing cover plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a plastic particle mixing device, including a mixing chamber 1, a stirring mechanism 2, and a support frame 5. In this embodiment, the mixing chamber 1 is a cylindrical structure, and its top is detachably installed with a top cover. The top rod is provided with a feed port. The stirring mechanism 2 includes a rotating shaft 201 rotatably arranged at the center inside the mixing chamber 1 through a bearing, a second rotation driving member 202 for driving the rotation of the rotating shaft 201, and a plurality of stirring blades 203 fixed on the outer peripheral wall of the rotating shaft 201. The second rotation driving member 202 can specifically be a motor, installed at the top of the mixing chamber 1. By driving the rotation of the rotating shaft 201 and the stirring blades 203 through the second rotation driving member 202, the plastic particles added into the mixing chamber 1 can be mixed and stirred.

[0023] The support frame 5 includes a support plate 501 horizontally fixed outside the mixing chamber 1 and four support legs 502 fixed to the bottom end of the support plate 501, which are used to provide support for the mixing chamber 1. Further, in order to facilitate walking, universal wheels can be installed at the bottom ends of the support legs 502.

[0024] Refer to the attached Figure 4 , a plurality of first through holes 101 are arranged in a circular array at the bottom end of the mixing chamber 1 with the center of the mixing chamber 1 as the center of the circle. A baffle 3 for closing and blocking the first through holes 101 is rotatably arranged at the bottom end of the mixing chamber 1 through a first rotation driving member 4. The baffle 3 is a circular plate adapted to the mixing chamber 1. Specifically, the baffle 3 can be rotatably installed at the bottom end inside the mixing chamber 1 through an annular slide rail. A plurality of second through holes 301 corresponding to the first through holes 101 one by one are arranged through the baffle 3. The first through holes 101 and the second through holes 301 can be specifically sector-shaped through holes concentric with the bottom end of the mixing chamber 1. The first rotation driving member 4 drives the baffle 3 to rotate, so that the second through holes 301 coincide with or separate from the first through holes 101. A material guiding table 302 with a gradually increasing size from top to bottom is arranged in the middle of the top end of the baffle 3, which is convenient for the plastic particles at the bottom to roll down in all directions and avoid accumulation in the middle. The bottom end of the rotating shaft 201 is rotatably arranged at the top end of the material guiding table 302 through a bearing, which can improve the rotation stability of the rotating shaft 201.

[0025] In this embodiment, the first rotation driving member 4 can be specifically a motor. The first rotation driving member 4 is installed at the bottom end inside the mixing chamber 1, and the first rotation driving member 4 is located inside the material guiding table 302. The output end of the first rotation driving member 4 is fixedly connected to the material guiding table 302, which can drive the material guiding table 302 and the baffle 3 to rotate synchronously.

[0026] Further, a material guiding pipe 6 is fixed to the bottom end of the mixing chamber 1. A sealing cover plate 7 is fixed to the bottom end of the material guiding pipe 6. A through hole adapted to the discharge port of the material guiding pipe 6 is arranged through the sealing cover plate 7. The sealing cover plate 7 is slidably connected to the support leg 502. A storage tank 8 is movably placed below the sealing cover plate 7. When discharging materials, the storage tank 8 is pushed below the sealing cover plate 7. The sealing cover plate 7 abuts against the top end of the storage tank 8, which can avoid dust flying during discharging. At the same time, the material guiding pipe 6 is made of flexible material and can be freely bent. Then, storage tanks 8 of different sizes can be selected according to needs, and at the same time, blockage of the material guiding pipe 6 can be avoided.

[0027] Working principle: During operation, the first rotation driving member 4 drives the baffle 3 to rotate, so that the second through hole 301 is completely separated from the first through hole 101, and the baffle 3 shields and closes the first through hole 101. The plastic particles added into the mixing chamber 1 are stirred and mixed by the stirring mechanism 2. After the mixing is completed, the storage tank 8 is placed below the sealing cover plate 7. The first rotation driving member 4 drives the baffle 3 to rotate, so that when the first through hole 101 and the second through hole 301 coincide, the plastic particles inside the mixing chamber 1 can fall, and enter the storage tank 8 through the material guiding pipe 6. The sealing cover plate 7 covers the inside of the storage tank 8 to avoid dust flying during material discharging and causing environmental pollution.

[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be construed as limiting the claimed rights.
