Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Specifically, it consists of a first stirring shaft 301, a second stirring shaft 302, and a stirring sleeve 303. When the transmission gears rotate, they drive the first stirring shaft 301 and the second stirring shaft 302 to rotate respectively through the first connecting shaft 203 and the second connecting shaft 204. The two stirring shafts rotate in opposite directions inside the stirring sleeve 303, forming a spiral stirring channel. This design of reverse rotation enables the plastic raw materials to be fully mixed and stirred inside the stirring sleeve 303, ensuring the uniformity and consistency of the plastic granules and improving the practicability.

[0024] The transmission assembly includes a driving motor 201 and a transmission shaft 202. The driving motor 201 is vertically installed on the support assembly, and the transmission shaft 202 is vertically installed on the driving motor 201 and connected to the driving motor 201.

[0025] A first transmission gear 205 is provided extending outward from the transmission shaft 202. The first transmission gear 205 is vertically installed on the support assembly, and one end of the first transmission gear 205 is provided with a second transmission gear 206 connected thereto.

[0026] Specifically, after the drive motor 201 is started, power is transmitted to the first transmission gear 205 through the transmission shaft 202. The first transmission gear 205 and the second transmission gear 206 mesh with each other. This gear transmission method ensures stable power transmission and can adjust the transmission ratio as needed to control the rotation speed of the stirring shaft. The adjustment of the transmission ratio has a direct impact on the stirring effect of the plastic raw materials and the extrusion speed. Therefore, in actual operation, the operator can flexibly adjust the transmission ratio according to different plastic raw materials and processing requirements, improving the practicality.

[0027] A first connecting shaft 203 is provided extending outward from the first transmission gear 205. The first connecting shaft 203 is vertically installed on the first transmission gear 205 and is connected to the first transmission gear 205 for driving the first connecting shaft 203 to rotate. A second connecting shaft 204 is provided extending outward from the second transmission gear 206. The second connecting shaft 204 is connected to the second transmission gear 206.

The discharge port 402 is opened at one end of the stirring sleeve 303 and is connected to the stirring sleeve 303.

[0030] Specifically, during the stirring process, the raw materials are added through the feeding hopper 401. After being stirred by the stirring sleeve 303, they are discharged from the discharge port 402. During the feeding process, the design of the discharge port 402 also plays a crucial role. The discharge port 402 is provided with discharge holes 403, and the size and quantity of the discharge holes 403 can be adjusted according to needs to control the extrusion speed and extrusion quantity. Whether the design of the discharge holes 403 is reasonable directly affects the product quality and production efficiency. Therefore, during actual operation, the operator needs to flexibly adjust the size and quantity of the discharge holes 403 according to different plastic raw materials and processing requirements.

[0031] The support assembly includes a base 101 and a workbench 102. The workbench 102 is vertically installed on the base 101. The workbench 102 is connected to the base 101 and is used to support the overall equipment. The drive motor 201 is located at the top of the workbench 102.

[0032] Specifically, the base 101 and the workbench 102 are the main support parts of the equipment. They are usually made of strong metal materials, which can withstand various forces and vibrations generated during the operation of the equipment, improving the stability of the equipment.

[0033] The workbench 102 extends outward to be provided with a support seat 103. The support seat 103 is vertically installed on the workbench 102. The support seat 103 is connected to the workbench 102 and is used to support the stirring sleeve 303. The workbench 102 extends outward to be provided with a housing 104. The housing 104 is vertically installed on the workbench 102. The housing 104 is connected to the workbench 102 and is respectively used to support the first transmission gear 205 and the second transmission gear 206.

The locking screw 502 is vertically installed on the sealing ring 501. The locking screw 502 is connected to the sealing ring 501 and is used to fix between the sealing rings 501. The limiting seat 503 is vertically installed on the workbench 102. The limiting seat 503 is connected to the stirring sleeve 303 and is used to limit the stirring sleeve 303.

[0036] Specifically, the sealing ring 501 is sleeved inside the stirring sleeve 303 and fits tightly with the stirring sleeve 303, ensuring the sealing performance of the stirring sleeve 303 and preventing the leakage of raw materials. The locking screw 502 is used to fix the sealing ring 501 on the stirring sleeve 303 to ensure that it will not loosen or fall off. The limiting seat 503 restricts the movement range of the stirring sleeve 303, enabling it to rotate only within a limited space. This precise positioning design ensures the stability and safety of the stirring sleeve 303 during operation.

[0037] By driving the first stirring shaft 301 and the second stirring shaft 302 to rotate simultaneously through the transmission assembly, a strong stirring effect can be formed inside the stirring sleeve 303, ensuring that the plastic raw materials are fully mixed and heated, thereby improving the quality and extrusion efficiency of plastic particles. Through the design of the feeding hopper 401, the discharge port 402, and the discharge holes 403, the addition of raw materials and the discharge of plastic particles are made more convenient and flexible. At the same time, raw materials of different sizes can be extruded and different shapes can be extruded, improving the practicality.
