[0021] Please refer to Figure 1 Figure 4 and Figure 5 ​​In this embodiment, the feeding unit includes a second rotary motor 11. The second rotary motor 11 is located at the left end of the cabinet 2. The output shaft of the second rotary motor 11 is connected to a first rotating shaft 12, which is located inside the main material bin 3. A second rotating shaft 13 is rotatably connected inside the color masterbatch bin 4. Both the first rotating shaft 12 and the second rotating shaft 13 have auger blades 14 on their outer walls. A transmission structure is provided between the first rotating shaft 12 and the second rotating shaft 13. The transmission structure includes a drive wheel 15. The drive wheel 15 is fixedly connected to the outer wall of the first rotating shaft 12, and a driven wheel 16 is fixedly connected to the outer wall of the second rotating shaft 13. Both the drive wheel 15 and the driven wheel 16 are located on the outside of the cabinet 2. A belt 17 is rotatably connected to both the drive wheel 15 and the driven wheel 16. The second rotary motor 11 serves as the power source for the entire feeding unit, providing rotational power. It transmits the power to the subsequent first rotating shaft 12 via its output shaft. The outer wall of the first rotating shaft 12 is tightly fixed with auger blades 14. When the second rotary motor 11 starts, the first rotating shaft 12 rotates accordingly, driving the auger blades 14 to push the main material forward from the main material bin 3. The second rotating shaft 13 is located in the color masterbatch bin 4 and is arranged parallel to the first rotating shaft 12. The second rotating shaft 13 is responsible for conveying the color masterbatch, ensuring that the color masterbatch can be mixed with the main material in a predetermined ratio. The driving wheel 15 is connected to the driven wheel 16 via a belt 17. When the first rotating shaft 12 rotates, the driving wheel 15 drives the belt 17 to rotate, thereby driving the driven wheel 16 and the second rotating shaft 13 to rotate.This transmission method ensures that the main material and color masterbatch can be transported synchronously and proportionally. The mixing unit includes a mixing shaft 18, the upper end of which is connected to the output shaft of the first rotary motor 6. The outer wall of the mixing shaft 18 is provided with a reciprocating thread, and the outer wall of the reciprocating thread is provided with a lifting structure. The outer wall of the mixing shaft 18 is integrally fixedly connected with a mixing rod 19. The lifting structure includes a lifting seat 20, which is threadedly connected to the outer wall of the reciprocating thread. The side end of the lifting seat 20 is symmetrically provided with fan blades 21, which drive the fan blades 21 to move vertically. The front and rear ends of the lifting seat 20 are provided with sliders 22. The inner walls of the front and rear sides of the box 1 are provided with slide rails 23 that are adapted to the sliders 22. The sliders 22 and slide rails 23 are slidably connected. The quantitative feeding unit includes an electric push rod 24, which is provided on the side end of the box 9. The telescopic end of the electric push rod 24 is provided with an adjusting plate 25, which drives the adjusting plate 25. The stirring shaft 18 has a reciprocating thread on its outer wall. The spiral shape of the reciprocating thread allows the lifting seat 20 to reciprocate vertically along the thread when the stirring shaft 18 rotates. This reciprocating motion not only enhances the uniformity of mixing, but also drives the vertical movement of the fan blade 21 through the up-and-down movement of the lifting seat 20, which helps to break up the agglomeration of materials and improve the mixing effect. In addition, the sliding connection between the slider 22 and the slide rail 23 ensures the stability of the lifting seat 20 during vertical movement. The stirring rod 19 rotates under the drive of the stirring shaft 18, shearing, squeezing and turning the materials to ensure that the materials can be fully mixed. The electric push rod 24 is the power source of the quantitative feeding unit. The electric push rod 24 drives the adjusting plate 25 to move back and forth through its telescopic end to realize the quantitative feeding of materials. The adjusting plate 25 can change the volume of the box 9 during the movement, thereby controlling the amount of materials fed and realizing precise quantitative feeding.

[0022] During operation, materials are first added to the main material bin 3 and the color masterbatch bin 4 through the feed inlet. Then, the first rotary motor 6, the second rotary motor 11, and the electric push rod 24 are started simultaneously. The electric push rod 24 drives the adjusting plate 25 to move inside the box 9 to adjust the volume of the box 9. At the same time, the second rotary motor 11 drives the first rotating shaft 12 to rotate, which drives the auger blades 14 to convey the main material from the main material bin 3 forward. The rotation of the first rotating shaft 12 also drives the rotation of the drive wheel 15. Through the transmission action of the belt 17, the second rotating shaft 13 rotates synchronously to convey the color masterbatch, ensuring that the color masterbatch can be mixed with the main material in the box 1 according to the preset ratio.

[0023] At this time, the No. 1 rotary motor 6 drives the stirring shaft 18 to rotate, which in turn drives the stirring rod 19 to rotate, so as to fully mix the materials. At the same time, the lifting seat 20 moves up and down under the action of the reciprocating screw, and drives the fan blade 21 to move vertically, further improving the mixing effect. After the mixing is completed, the material is discharged from the discharge pipe 8 and enters the box 9. When the material reaches the predetermined amount, it is discharged through the discharge pipe 10.

[0024] Through the above steps, this solution achieves the synchronous and proportional delivery of main materials and color masterbatch through the design of the feeding unit, ensuring the accuracy of mixing. During the mixing process, the reciprocating thread on the mixing shaft 18 drives the lifting seat 20 and the fan blade 21 to move vertically, and in conjunction with the rotational shearing function of the mixing rod 19, the uniformity and effect of mixing are improved. In addition, the quantitative feeding unit can precisely control the volume of the box 9, thereby achieving precise quantitative feeding of materials, effectively improving production efficiency and ensuring product quality. It solves the problem that traditional feeding methods are difficult to achieve synchronous delivery and quantitative feeding of main materials and color masterbatch, which easily leads to color difference in plastic products, waste of raw materials, and substandard product performance.
