[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0024] Secondly, the "one embodiment" or "embodiment" referred to herein is intended to mean a specific feature, structure, or characteristic under at least one implementation of the utility model. The "in one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent or alternative to other embodiments.

[0025] Embodiments

[0026] Referring to Figs. 1-4 For the embodiments of the utility model, the embodiments provide a stirring and mixing equipment for plastic product processing, which comprises,

[0027] The mixing mechanism 100 comprises a heating assembly 101, a plurality of supporting legs 102 fixedly installed at the bottom of the heating assembly 101, a stirring assembly 103 arranged at the top of the heating assembly 101, and a mixing tank 104 fixedly installed at the top of the heating assembly 101.

[0028] The stirring assembly 103 comprises a shaft 103a, a plurality of supporting rods 103b fixedly installed on the outer surface of the shaft 103a, a plurality of curved paddles 103c arranged around the outer side of the shaft 103a and fixedly connected to the end portions of the supporting rods 103b, an inner layer paddle 103d fixedly installed on the outer surface of the shaft 103a, a sealing disc 103e fixedly installed at the end portion of the shaft 103a, and a positioning rod 103f fixedly installed at the bottom of the inner layer paddle 103d.

[0029] The heating assembly 101 in the mixing mechanism 100 provides a suitable temperature environment for material mixing, the stirring assembly 103 stirs and mixes the material, and the mixing tank 104 provides a mixing space, which helps to improve the efficiency and quality of material mixing in the plastic product processing process. The curved paddles 103c are arranged around the outer side of the shaft 103a and fixedly connected to the end portions of the supporting rods 103b, and the inner layer paddle 103d is fixedly installed on the outer surface of the shaft 103a. This structure can stir the material at different levels in the mixing tank 104. The curved paddles 103c can push the material towards the tank wall and the tank bottom, and the inner layer paddle 103d can stir the material in the center of the tank, thereby improving the uniformity of material mixing.

[0030] Specifically, the heating assembly 101 comprises a lower hopper 101a fixedly installed at the bottom of the mixing tank 104, a fixed rod 101b fixedly installed on the inner wall of the lower hopper 101a, a ring 101c fixedly installed on the outer side of the fixed rod 101b in cooperation with the first bolt 101d, a heating wire 101e gradually tapered and spirally arranged on the inner wall of the lower hopper 101a, a support 101f fixedly installed in the inner cavity of the lower hopper 101a, a positioning piece 101g arranged at the top of the support 101f, and a lower discharge pipeline 101h fixedly installed at the bottom of the lower hopper 101a.

[0031] Wherein, the heating wire 101e can make the material in the lower hopper 101a get more uniform heating. Due to the taper design of the heating wire 101e, the shape of the lower hopper 101a can be adapted to ensure that the material near the wall of the lower hopper 101a or the center can be fully heated. Uniform heating can prevent local overheating from causing a decline in plastic performance.

[0032] Further, the positioning member 101g includes a shaft seat 101g-1 fixedly installed on the top of the support 101f, a ring piece 101g-2 fixedly installed on the top of the shaft seat 101g-1 in cooperation with the second bolt 101g-3, and a limiting groove 101g-4 opened in the inner wall of the shaft seat 101g-1. The shaft rod 103a is fixedly installed in the inner cavity of the shaft seat 101g-1 through a bearing.

[0033] Wherein, the positioning member 101g plays a positioning role on the stirring assembly 103. During stirring, accurate positioning can ensure the stable rotation of the shaft rod 103a of the stirring assembly 103, reducing the deviation and wear of the shaft. When high-speed stirring, good positioning can ensure that the gap between the stirring paddle and the wall of the mixing tank 104 remains stable, preventing the paddle from colliding with the tank wall.

[0034] Preferably, the mixing mechanism 100 further comprises a feeding pipe 105 fixedly installed on the top of the mixing tank 104, and a driving motor 106 fixedly installed on the top center of the mixing tank 104. The end of the shaft rod 103a is fixedly connected with the output end of the driving motor 106 through a shaft coupling. The heating wire 101e gradually penetrates the inner cavity of the ring sleeve 101c and gradually decreases in radius.

[0035] In use, first, the material is poured into the mixing tank 104 through the feeding pipe 105. The stirring assembly 103 is driven by the driving motor 106 to rotate the shaft rod 103a, which drives the curved paddle 103c and the inner paddle 103d to stir in multiple layers, ensuring that the material is fully mixed. The shaft seat 101g-1 provides an installation position for the shaft rod 103a. The ring piece 101g-2 cooperates with the second bolt 101g-3 to firmly fix the shaft rod 103a in the shaft seat 101g-1, ensuring that the center of rotation of the shaft rod 103a coincides with the center of the mixing tank 104.

[0036] When heating of the material is required, the heating assembly 101 uniformly heats the material through the taper spiral heating wire 101e, and smoothly discharges the material through the lower hopper 101a and the lower discharge pipe 101h. When the heating wire 101e needs to be replaced or repaired, the ring sleeve 101c and the heating wire 101e can be removed by loosening the first bolt 101d. After stirring is completed, the lower discharge pipe 101h can ensure that the heated material smoothly flows out of the lower hopper 101a.

[0037] In summary, the curved paddle 103c and the inner layer paddle 103d in the stirring assembly 103 achieve a multi-level paddle structure, which can increase the contact area with the material, and can more effectively stir the material at the same rotating speed, can shorten the time required for the material to reach a uniformly mixed state, improve production efficiency, the heating assembly 101 can make the heat more concentrated on the material in the lower hopper 101a, reduce the heat loss to the surrounding environment, and the heating wire 101e can heat the material to the required temperature faster under the same power input, improving energy utilization efficiency.
