[0043] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0044] Example: Figure 1-4 As shown, the present invention is a high-efficiency and low-energy consumption multi-color mixed particle production device, including an extruder body 1, a base table 2 is fixedly provided at the bottom end of the extruder body 1, an extrusion pump 3 is fixedly provided on one side of the extruder body 1, a feed chute 4 is fixedly provided on the top of the extruder body 1, a plurality of equidistant and symmetrically distributed L-shaped support frames 5 are fixedly provided on the top of the base table 2, the same mounting platform 6 is fixedly provided on the top of the plurality of L-shaped support frames 5, and a plurality of material boxes 7 arranged on one side of the extruder body 1 are fixedly provided on the top of the mounting platform 6.

[0045] Among them, the number of material boxes 7 is twelve, and the material boxes 7 include a feed box 8, a feeding box 9 and a switching box 10 that are adjacent to each other and equidistantly arranged, a mixing box 11, a return box 12 and an inspection box 13. The number of the switching boxes 10 and the feeding boxes 9 are four each. Through the provision of the feed box 8, the feeding box 9, the switching box 10, the mixing box 11, the return box 12 and the inspection box 13, when producing multi-color mixed particles, the operations of replenishing, switching, feeding, mixing, returning and inspecting can be performed in sequence, so as to realize precise operations such as color selection, coloring, mixing and inspection of the multi-color mixed particles, thereby ensuring the production quality of the multi-color mixed particles.

[0046] Among them, a material guide pipe 14 is fixedly provided on the top of the four feeding boxes 9 and the return box 12, a flange 15 is fixedly provided on the material guide pipe 14, a multi-color marking tube 16 is fixedly provided on the top of the flange 15, and an independent electromagnetic control valve 17 is fixedly provided on the feeding box 9 and the return box 12 and at the bottom of the flange 15. Through the material guide pipe 14, the flange 15 and the multi-color marking tube 16, the flange 15 can connect the material guide pipe 14 and the multi-color marking tube 16, and then connect different color particle extruders according to the markings of the multi-color marking tube 16, so as to realize the precise introduction of the color-changing particles, and the independent electromagnetic control valve 17 can individually control the entry of the required color particles and intercept the unnecessary color particles, so as to realize the production of different multi-color mixed particles.

[0047] Among them, five material extrusion tubes 18 are connected through the interior of the material box 7, and a closing valve 19 is arranged on the side of the material extrusion tube 18. The top ends of the four switching boxes 10 are fixedly connected to the same control box 20. A centralized control chip electrically connected to the closing valve 19 is fixedly arranged inside the control box 20. Through the provided closing valve 19, when the closing valve 19 is opened, the multi-color particle plastic in the material box 7 is mixed and colored and discharged through the pipeline. When a certain closing valve 19 is closed, the material extrusion tube 18 cannot output the multi-color plastic particles. The five material extrusion tubes 18 can effectively improve the output efficiency of the multi-color plastic particles, and at the same time reduce the accumulation of the multi-color plastic particles, facilitate the uniform mixing of the multi-color plastic particles, and improve the production effect.

[0048] A high-efficiency and low-energy consumption multi-color mixed color particle production process comprises the following steps:

[0049] S1) Particle extrusion and conveying

[0050] Utilizing the combinable characteristics of the extruder's screw elements combined with pigment fluidization technology, the conveying and mixing elements are arranged in sections;

[0051] S2) Feeding

[0052] Taking advantage of the adjustability of the extruder's mixing distribution, multiple feeding ports are set in the direction of the material flow, different types of pigments are injected through multiple feeding buckles, and the injection amount and injection flow rate are accurately controlled by the control valve;

[0053] S3) Multi-level color mixing

[0054] By adjusting and distributing the dispersing elements, the material can achieve multiple color levels in three dimensions, ultimately achieving a color mixing effect;

[0055] S4) Multi-color mixing

[0056] The color mixing of plastic particles is achieved by utilizing the rotation effect of the motor and cooperating with the rotation of the single screw. The quality of the mixed plastic particles can be adjusted by controlling the mixing time.

[0057] S5) Material return

[0058] In case of wrong pigment selection or wrong injection ratio, use pipeline to extract wrong particles to avoid mixing with qualified products;

[0059] S6) Particle Detection

[0060] The mixed particles are sampled and tested, and unqualified particles are promptly rejected, which improves the production quality of plastic particles;

[0061] S7) Particle discharge

[0062] The qualified particles are discharged.

[0063] The extruder in step S1 is an assembled double-screw structure, and the plastic raw material is any plastic material that can be extruded using a twin-screw.

[0064] Among them, in step S2, there are several feeding methods, including pumping, screw propulsion and dripping, and different connecting pipes are connected according to the feeding methods, and different feeding methods are used to control the feeding amount and feeding rate.

[0065] In step S2, several types of colorants are provided, including slurry, particles, powder and paste, and the corresponding colorant type is selected according to the subsequent mixing power.

[0066] Working principle: This kind of high-efficiency and low-energy consumption multi-color mixed color particle production device and its manufacturing process are different from the existing technology. They have a reasonable structure, are easy to use, and are simple to operate, allowing users to understand the working principle simply and clearly. When in use, the first step is to transport the elements, and use the screw elements of the extruder to arrange the transport mixing elements in sections, and then the pellets enter the feed box 8, and then continue to be extruded by the extrusion pump 3, and then the pellets enter the feeding box 9 for feeding. Multiple feeding boxes 9 are set in the direction of material flow, and different types of pigments are injected through multiple feeding boxes 9, and the injection amount and injection flow rate are accurately controlled by an independent electromagnetic control valve 17. In this process, when the closing valve 19 in the switching box 10 is opened, the multi-color particles in the material box 7 The plastics are mixed and colored and discharged through the pipeline. When a certain closing valve 19 is closed, the material extrusion tube 18 cannot output multi-color plastic particles. Then, multi-level color mixing and multi-color mixing are carried out. The rotation effect of the motor on the mixing box 11 is used in conjunction with the rotation of the single screw to achieve color mixing of the plastic particles. When the wrong pigment is selected or the wrong injection ratio occurs, the wrong particles are extracted from the return box 12 through a pipeline to avoid mixing with qualified particles. Then, particle detection is carried out, and the mixed particles are sampled and tested from the inspection box 13. Unqualified particles are promptly returned, and then qualified particles are discharged. In this way, the entire multi-color mixed particle production process can be completed.
