[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0023] like Figure 1 As shown in the figure, the injection device for processing plastic particles of this utility model includes:

[0024] The conveyor box 1 and the forming component are provided. A drive shaft 2 is rotatably installed in the inner hole of the conveyor box 1. A spiral conveying blade 3 is coaxially installed on the drive shaft 2. The spiral conveying blade 3 is rotatably installed in the cavity of the conveyor box 1. A connecting shaft 4 is coaxially installed on the spiral conveying blade 3. The connecting shaft 4 is rotatably installed inside the shaft cavity of a hollow shaft 5. A spiral extrusion blade 6 is coaxially installed on the hollow shaft 5. The hollow shaft 5 is rotatably installed in the shaft hole of the conveyor box 1. A heating component 7 is installed on the outer wall of the conveyor box 1. A discharge port is provided at the bottom of one side of the conveyor box 1. The forming component is located at the discharge port of the conveyor box 1. An addition port is provided at the top of the other side of the conveyor box 1.

[0025] The drive assembly, mounted on the conveyor box 1, provides rotational power to the connecting shaft 4 and the hollow shaft 5. The screw conveyor blade 3 is rotated and supported inside the conveyor box 1 via the transmission shaft 2, and the screw extrusion blade 6 is rotated and supported inside the conveyor box 1 via the hollow shaft 5. The drive assembly provides rotational power to both the screw conveyor blade 3 and the screw extrusion blade 6. The screw conveyor blade 3 stably conveys the plastic particles, and the heating assembly 7 heats the conveyed plastic particles to a molten state. When the molten plastic particles are conveyed to the molding assembly via the screw extrusion blade 6, the density is increased, the presence of air bubbles is reduced, and the quality is improved. Using a single drive assembly to simultaneously drive the connecting shaft 4 and the hollow shaft 5 simplifies the equipment structure, reduces energy consumption and maintenance costs, and the design of the feeding port facilitates the addition of raw materials while reducing the operator's contact with high-temperature components, improving operational safety and convenience, and ultimately enhancing the quality of the finished product.

[0026] like Figure 1 As shown in the figure, as a preferred embodiment, the molding assembly includes a mounting component 8 disposed at the discharge port of the conveyor box 1. The mounting component 8 is disposed on a conical structure, and a molding die 9 is disposed on the mounting component 8 via a connecting component. The molding die 9 is provided with multiple sets of molding holes. The multiple sets of molding holes on the molding die 9 can precisely control the size and shape of the plastic product, thereby improving molding accuracy. The conical structure of the mounting component 8 can effectively guide molten plastic particles into the molding die 9, reduce the generation of air bubbles, and improve the quality of the plastic product. The connection between the molding die 9 and the mounting component 8 via the connecting component makes it simple and quick to change molding dies of different specifications, improving production flexibility. The design of multiple sets of molding holes allows for the production of multiple products at the same time, significantly improving production efficiency.

[0027] like Figure 1 As shown in the figure, as a preferred embodiment, the connecting assembly includes fixing members 10 symmetrically arranged at both ends of the mounting member 8. Connecting rods 11 are inserted and pulled into the through holes of the fixing members 10. Both sets of connecting rods 11 are set on the forming mold 9. The connecting rods 11 are provided with external threads, and nuts 12 are provided at the external threads of the connecting rods 11. Through the cooperation of the connecting rods 11 and nuts 12 in the connecting assembly, the forming mold 9 can be quickly disassembled and installed, which greatly improves the efficiency of changing molds of different specifications. The plug-in design of the connecting rods 11 allows operators to easily complete the mold change without complicated tools or professional knowledge.

[0028] like Figure 1 As shown in the figure, in a preferred embodiment, the drive assembly includes a drive motor 13 mounted on the conveyor box 1. The output end of the drive motor 13 is coaxially mounted on the power shaft 14. Both the power shaft 14 and the connecting shaft 4 are coaxially mounted with transmission gears 15, which mesh and drive each other. A drive gear 16 is coaxially mounted on the power shaft 14, and a driven gear 17 is coaxially mounted on the hollow shaft 5. The drive gear 16 and the driven gear 17 mesh and drive each other. The number of teeth on the drive gear 16 is less than the number of teeth on the driven gear 17. The power shaft 14 is rotatably mounted on the conveyor box 1, and the conveyor box 1 is equipped with an isolation device. The drive gear 16, driven gear 17, and two sets of transmission gears 15 are all housed within the isolation component 21. Through gear transmission, power can be efficiently and smoothly transmitted to the spiral conveyor blade 3 and the spiral extrusion blade 6, improving the overall transmission efficiency of the system. The drive gear 16 and driven gear 17 have different tooth ratios, enabling variable speed transmission. This allows the spiral extrusion blade 6 to rotate at a different speed than the spiral conveyor blade 3, optimizing the material conveying process. A single drive motor 13 simultaneously drives the connecting shaft 4 and the hollow shaft 5, simplifying the equipment structure and reducing the space occupied by the equipment.

[0029] like Figure 1 As shown in the figure, as a preferred embodiment, the conveyor box 1 is provided with multiple sets of auxiliary components 18, and the bottom of the auxiliary components 18 is provided with support feet 19. The support feet 19 at the bottom of the auxiliary components 18 can ensure that the conveyor box 1 is placed stably on the ground, which improves the stability of the entire equipment. The design of the support feet 19 can be adjusted in height according to actual needs, so that the conveyor box 1 can adapt to different working environments and requirements.

[0030] like Figure 1 As shown in the figure, as a preferred embodiment, an addition funnel 20 is provided at the addition port of the conveyor box 1; the design of the addition funnel 20 can more conveniently introduce plastic particles into the interior of the conveyor box 1, thereby improving the efficiency of raw material addition.

[0031] like Figure 1As shown in the figure, the preferred solution operates as follows:

[0032] Plastic particles enter through the feeding port at the top of the conveying box 1 and are evenly distributed inside the conveying box 1 through the feeding funnel 20. The drive motor 13 drives the power shaft 14 to rotate, which in turn drives the connecting shaft 4 to rotate through the transmission gear 15, driving the spiral conveying blade 3 to rotate, thereby pushing the plastic particles to one side of the conveying box 1. During the conveying process, the heating component 7 heats the plastic particles in the conveying box 1, causing them to gradually melt. The driven gear 17 on the hollow shaft 5 rotates through meshing with the drive gear 16, driving the spiral extrusion blade 6 to rotate. The molten plastic particles are further compressed by the spiral extrusion blade 6, increasing their density and reducing air bubbles. Then, they are discharged through the discharge port of the conveying box 1. The discharged molten plastic particles enter the molding component and are guided by the conical structure of the mounting component 8 into the multiple molding holes in the molding mold 9 for molding. When it is necessary to change the molding mold 9 of different specifications, simply loosen the nut 12 and pull out the connecting rod 11 to easily disassemble and install the new molding mold.

[0033] The injection device for processing plastic particles of this utility model can be installed, connected, or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effects.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
