Description

Technical Field

[0001] This invention relates to the field of granule mixing of plastic packaging box materials, and more specifically to a granule mixer for color matching of plastic packaging box materials. Background Technology

[0002] Plastic packaging boxes are containers used to package, protect, or display products, made primarily of synthetic or natural polymer resins, with the addition of additives such as plasticizers and stabilizers, and formed through specific processes such as injection molding, vacuum forming, and blow molding. The selection of materials for plastic packaging boxes must balance performance and cost. Common materials include PET (polyethylene terephthalate), PP (polypropylene), PS (polystyrene), and PVC (polyvinyl chloride). Color matching of plastic packaging box materials is the process of adjusting the pigment ratio to make the plastic color match the target color card.

[0003] Granulation mixing of plastic packaging box materials is a crucial step in plastic processing. It refers to the process of uniformly dispersing resin matrices such as PET, PP, and PS with additives such as pigments, plasticizers, stabilizers, and lubricants through physical means to form a composite material with consistent composition and stable performance. Its core purpose is to ensure that the components of the material are evenly distributed at the microscopic level, thereby meeting the requirements of plastic packaging boxes for physical properties, chemical stability, and appearance quality. In this process, the granulator mixer uses high-speed rotating blades to make the material vortex and tumble and rub, achieving uniform color mixing and ensuring that the pigment and resin are fully mixed, avoiding color spots or flow marks. The granulator mixer ensures the uniformity of color mixing in plastic packaging box materials and avoids quality defects caused by uneven mixing.

[0004] Existing pellet mixers lack the ability to mix materials both internally and externally. This results in the pellets only flowing and being stirred in a limited direction during the mixing process, which can easily lead to insufficient mixing in local areas. Furthermore, due to the lack of a complex flow field effect that works both internally and externally, the relative movement and material exchange between the pellets are slow, requiring a longer mixing time to achieve a relatively uniform state.

[0005] Therefore, it is necessary to invent a granular mixer for color matching of plastic packaging box materials to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a granular mixer for color matching of plastic packaging box materials. This granular mixer possesses the ability to mix materials both internally and externally. The external hopper rotates clockwise, causing the granules to rotate as a whole, creating a macroscopic material flow trend. Meanwhile, the internal stirring rod rotates counterclockwise, microscopically stirring, breaking up, and recombinizing the granules. This synergistic effect allows the granules to come into contact with each other in all directions and at multiple levels during the mixing process, effectively breaking up granule agglomeration. Furthermore, the different rotation directions of the internal and external hoppers create a complex flow field, accelerating the relative movement and material exchange between the granules, and reducing... The reduced mixing time allows for more thorough mixing of granules within a shorter cycle, improving production efficiency and reducing production costs. This addresses the shortcomings of existing granule mixers, which lack the ability for coordinated internal and external mixing. In such cases, mixers relying on a single stirring method or rotation direction can only achieve limited directional flow and mixing of granules, leading to insufficient mixing in localized areas. Furthermore, the lack of a complex, coordinated internal and external flow field results in slower relative movement and material exchange between granules, requiring longer mixing times to achieve a relatively uniform state.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a granular mixer for color matching of plastic packaging box materials, comprising a base, a stiffening column fixedly installed on the top of the base, a servo motor fixedly installed on the outside of the stiffening column, a rotating rod fixedly installed at the output end of the servo motor, an outer hopper frame fixedly installed at the other end of the rotating rod, a drive motor fixedly installed at the bottom of the outer hopper frame, an outer turntable fixedly installed at the output end of the drive motor, a first wheel fixedly installed on the top of the outer turntable, a hopper tray fixedly installed on the top of the first wheel, a mixing hopper fixedly installed on the top of the hopper tray, and a connecting shaft fixedly installed on the top of the mixing hopper; An external reinforcing frame is fixedly installed on the outside of the outer hopper frame. A first turntable is rotatably connected to the top of the external reinforcing frame. A second rotating belt is rotatably connected to the outside of the first turntable. A second turntable is rotatably connected to the other side of the inside of the second rotating belt. A center rod is fixedly installed at the bottom of the second turntable. An internal hexagonal frame is fixedly installed on the top inside the mixing hopper. A mixing fixing rod is fixedly installed at the center inside the internal hexagonal frame. An internal transmission groove is opened inside the mixing fixing rod. An adjusting rod is rotatably connected inside the internal transmission groove. A first bevel tooth is fixedly installed on the outside of the adjusting rod.

[0008] Preferably, both outer sides of the base are threaded with positioning cones, and the upper part of the positioning cones is threaded with fastening bolts. External protective railings are fixedly installed on both outer sides of the stiffening column.

[0009] Preferably, the mixing hopper has a double feed inlet on its upper exterior and a discharge outlet on its exterior, and valves are provided on the exterior of the double feed inlet and the discharge outlet.

[0010] Preferably, the first wheel is rotatably connected to the outside of a first rotating belt, and a second wheel is rotatably connected to the other side of the inside of the first rotating belt.

[0011] Preferably, a linkage rod is fixedly installed above the second wheel, and an upper transmission rod is fixedly installed on the top of the linkage rod. Both the linkage rod and the upper transmission rod are rotatably connected to the outer reinforcement frame.

[0012] Preferably, an outer bracket is fixedly installed above the outer hopper frame, a limit rod is fixedly installed above the second turntable, and the upper transmission rod is fixedly connected to the first turntable.

[0013] Preferably, an upper fixing sleeve is fixedly installed inside the upper part of the outer hopper frame, and the connecting shaft is rotatably connected to the inside of the upper fixing sleeve. The connecting shaft is hollow.

[0014] Preferably, the bottom end of the central rod is fixedly connected to the top end of the adjusting rod, and the outer two sides of the first bevel tooth are engaged with the second bevel tooth.

[0015] Preferably, a sidewall rod is fixedly installed inside the second conical tooth, the sidewall rod is rotatably connected inside the mixing fixing rod, and a vertical stirring rod is fixedly installed at the other end of the sidewall rod.

[0016] Compared with the prior art, the technical effects and advantages provided by the present invention in the above technical solution are as follows: The rotating mechanism, consisting of a first wheel and a first turntable, causes the mixing hopper inside the outer hopper frame to rotate, driving the plastic packaging material coloring granules inside to rotate externally. Then, influenced by the rotation of the second turntable, the central rod and adjusting rod internally drive the bevel gear transmission mechanism, which in turn drives the stirring rod outside the mixing fixing rod to internally mix the plastic packaging material coloring granules inside the mixing hopper. Thus, the forward rotation of the outer hopper is linked to the reverse rotation of the internal granules, and combined with the rotation of the entire mixing hopper driven by the outer hopper frame, this gives the plastic packaging material coloring granule mixer its internal... The external hopper rotates forward, causing the entire granule to rotate and creating a macroscopic material flow trend. Meanwhile, the internal stirring rod rotates in reverse, stirring, breaking up, and recombinating the granules at a microscopic level. This synergistic effect allows the granules to come into contact with each other in all directions and at multiple levels during the mixing process, effectively breaking up granule agglomeration. Moreover, the different rotation directions inside and outside create a complex flow field, accelerating the relative movement and material exchange between the granules, reducing the mixing time, and enabling the granules to be fully mixed in a shorter cycle, thereby improving production efficiency and reducing production costs.

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] This invention provides, for example Figure 1-8The illustrated plastic packaging box material color mixing granule mixer includes a base 1, a stiffening column 2 fixedly installed on the top of the base 1, a servo motor 3 fixedly installed on the outside of the stiffening column 2, a rotating rod 4 fixedly installed at the output end of the servo motor 3, an outer hopper frame 5 fixedly installed at the other end of the rotating rod 4, a drive motor 9 fixedly installed at the bottom of the outer hopper frame 5, an outer turntable 10 fixedly installed at the output end of the drive motor 9, a first wheel 11 fixedly installed on the top of the outer turntable 10, a hopper tray 12 fixedly installed on the top of the first wheel 11, a mixing hopper 13 fixedly installed on the top of the hopper tray 12, and a connecting shaft 14 fixedly installed on the top of the mixing hopper 13. The base 1 and stiffening column 2 provide a stable mounting platform for the components above, reducing the risk of easy shaking or displacement due to vibration or external force during operation, and also providing stable support for the rotation of the mixing hopper 13 in the outer hopper frame 5.

[0022] An external reinforcing frame 1502 is fixedly installed on the outside of the outer hopper frame 5. A first turntable 16 is rotatably connected to the top of the external reinforcing frame 1502. A second rotating belt 17 is rotatably connected to the outside of the first turntable 16. A second turntable 18 is rotatably connected to the other side of the inside of the second rotating belt 17. A center rod 21 is fixedly installed at the bottom of the second turntable 18. An internal hexagonal frame 23 is fixedly installed on the top inside the mixing hopper 13. A mixing fixing rod 24 is fixedly installed in the center of the internal hexagonal frame 23. An internal transmission groove 2401 is opened inside the mixing fixing rod 24. An adjusting rod 2402 is rotatably connected inside the internal transmission groove 2401. A first bevel tooth 2403 is fixedly installed on the outside of the adjusting rod 2402.

[0023] The central rod 21, driven by the first turntable 16, passes through the hollow connecting shaft 14. This ensures that the mixing hopper 13, when rotating normally outside the outer hopper frame 5, will not affect the rotation of the internal adjusting rod 2402 driven by the central rod 21. Thus, through linkage, the internal bevel gear transmission mechanism composed of the first bevel gear 2403 is driven to operate. Furthermore, in the above structure, both outer sides of the base 1 are threaded with positioning cones 6, and the upper part of the positioning cones 6 is threaded with fastening bolts 7. External protective railings 8 are fixedly installed on both outer sides of the stiffening column 2.

[0024] Furthermore, in the above structure, a double feed inlet 1301 is provided on the upper part of the mixing hopper 13, and a discharge outlet 1302 is provided on the outside of the mixing hopper 13. Valves are provided on the outside of the double feed inlet 1301 and the discharge outlet 1302.

[0025] By setting threaded positioning cones 6 and fastening bolts 7 on both sides of the machine base 1, the equipment can be accurately positioned and its connection with the ground can be strengthened, effectively preventing shaking during operation. In addition, the mixing hopper 13 has a double feed port 1301 on the upper part of the outside, which can simultaneously or in batches feed different granules, improving feeding efficiency and flexibility.

[0026] Furthermore, in the above structure, the first rotating belt 15 is rotatably connected to the outside of the first rotating belt 11, and the second rotating belt 1501 is rotatably connected to the other side of the inside of the first rotating belt 15.

[0027] Furthermore, in the above structure, a linkage rod 1503 is fixedly installed above the second wheel 1501, and an upper transmission rod 1504 is fixedly installed on the top of the linkage rod 1503. Both the linkage rod 1503 and the upper transmission rod 1504 are rotatably connected to the outer reinforcement frame 1502.

[0028] Furthermore, in the above structure, an outer bracket 19 is fixedly installed above the outer hopper frame 5, a limit rod 20 is fixedly installed above the second turntable 18, and the upper transmission rod 1504 is fixedly connected to the first turntable 16.

[0029] The first turntable 11 drives the second turntable 1501 via the first rotating belt 15. In conjunction with the rotational connection of the linkage rod 1503 and the upper transmission rod 1504, a multi-stage transmission system is constructed. This system not only achieves stable transmission and distribution of power among different components but also enhances transmission flexibility. The outer bracket 19 and the outer hopper frame 5 are integrated into a single mechanism. The top of the limiting rod 20 is inserted into the interior of the outer bracket 19, thereby providing support for the rotating second turntable 18 and additional support for the upper structure of the equipment, thus improving overall stability.

[0030] Furthermore, in the above structure, an upper fixing sleeve 22 is fixedly installed on the upper inside of the outer hopper frame 5, and a connecting shaft 14 is rotatably connected to the inside of the upper fixing sleeve 22. The connecting shaft 14 is hollow.

[0031] Furthermore, in the above structure, the bottom end of the center rod 21 is fixedly connected to the top end of the adjusting rod 2402, and the outer sides of the first bevel tooth 2403 are engaged with the second bevel tooth 2404.

[0032] Furthermore, in the above structure, a sidewall rod 2405 is fixedly installed inside the second conical tooth 2404, and the sidewall rod 2405 is rotatably connected inside the mixing fixing rod 24. A vertical stirring rod 25 is fixedly installed at the other end of the sidewall rod 2405. The rotation of the second turntable 18 drives the central rod 21 and the adjusting rod 2402 to internally drive the bevel gear transmission mechanism, which in turn drives the vertical stirring rod 25 outside the mixing fixed rod 24 to internally mix and stir the plastic packaging box material coloring granules inside the mixing hopper 13, forming a linkage effect and thus completing the mixing work. Working principle of this invention: Refer to the instruction manual appendix Figure 1 - Figure 8 When using the plastic packaging box material color mixing granule mixer, the granules to be mixed are first fed into the mixing hopper 13 through the double feed port 1301. Then, the drive motor 9 drives the fixedly connected outer turntable 10 and the first wheel 11 to rotate the mixing hopper 13. The internal space of the outer hopper frame 5 is sufficient to support the rotation of the mixing hopper 13 inside. Since the connecting shaft 14 at the top of the mixing hopper 13 is sleeved inside the upper fixed sleeve 22 of the outer hopper frame 5, the rotation of the outer hopper will not affect the rotation of the internal stirring rod. Next, the rotation of the first wheel 11 causes the first wheel 11, the first rotating belt 15, and the second wheel 1501 to drive the linkage rod 1503 and the upper transmission rod 1504 on the outer reinforcing frame 1502 to rotate synchronously. The above-mentioned transmission method also provides rotational power to the first turntable 16. At this time, the first wheel 11, together with the first turntable 16, the second rotating belt 17, and the second turntable 18, constitute a turntable transmission mechanism. This turntable transmission mechanism can drive the center rod 21 and the adjusting rod 2402 to drive the bevel gear transmission mechanism composed of the first bevel gear 2403 and the second bevel gear 2404 inside the mixing fixing rod 24, thereby causing the vertical stirring rod 25 on the outside of the mixing fixing rod 24 to rotate synchronously. The rotating vertical stirring rod 25 internally mixes and stirs the plastic packaging box material coloring granules inside the mixing hopper 13 with the outer hopper frame. The rotation of the mixing hopper 13, driven by the rotation of the outer hopper, creates a coordinated mixing capability between the inner and outer parts. The forward rotation of the outer hopper drives the overall rotation of the granules, forming a macroscopic material flow trend. The reverse rotation of the inner stirring rod stirs, disperses, and recombines the granules at a microscopic level, allowing the granules to come into contact with each other in all directions and at multiple levels during the mixing process. This effectively breaks up the granule agglomeration. Furthermore, during the rotational mixing process, by closing the external valves of the dual inlet 1301 and outlet 1302, the servo motor 3 drives the entire outer hopper frame 5 to rotate the mixing hopper 13 up and down inside the outer protective railing 8. This further improves the mixing efficiency of the granule mixer for color matching of plastic packaging box materials, ensuring that the mixed granules meet the color matching requirements of plastic packaging box materials. Finally, the mixed granules are discharged through the outlet 1302 and can be put into use.

[0033] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
