Abstract

This utility model proposes an automatic mixing and feeding machine for plastic particles and color masterbatch, including a base. An angle adjustment mechanism is fixedly installed on the top of the base, and a spiral feeding mechanism is movably installed on the inner side of the angle adjustment mechanism. During the application of this technical solution, the conical spiral stirring auger of the mixing mechanism drives the material to roll upward to enhance the mixing uniformity, and drives it downward to push the material to the discharge position. The feeding-related structure guides the material to enter in a concentrated manner, so that the plastic particles and color masterbatch can be fully mixed before feeding, avoiding material scattering and insufficient mixing, and ensuring that the mixed materials enter the subsequent feeding stage evenly. This achieves the effect of improving the mixing uniformity of materials and ensuring smooth conveying. It solves the problem of uneven dispersion of color masterbatch and the appearance of color spots or streaks caused by the lack of a stirring structure in the prior art. At the same time, it can also avoid the problems of easy blockage of material conveying, large ratio fluctuations, and inconsistent product performance.

Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to an automatic mixing and feeding machine for plastic particle color masterbatch. Background Technology

[0002] Currently, in the plastics processing industry, the automatic feeding device for recycled materials is a key piece of equipment for achieving automated production. Its core function is to automatically lift and transport recycled materials such as masterbatch and plastic particles to the hopper of the designated processing equipment, replacing manual feeding to improve the operating efficiency of the production line. Its conventional operating procedure is as follows: first, fix the device base in the designated position, align the discharge port of the automatic feeding barrel with the inlet of the subsequent processing equipment, then pour the recycled material into the feeding hopper, and start the automatic feeding barrel to complete the automatic conveying of the recycled material. However, in actual application, the recycled material is prone to accumulation after being poured into the feeding hopper, especially at the outlet of the feeding hopper, where blockages often occur, preventing the recycled material from smoothly entering the automatic feeding barrel and directly reducing the feeding efficiency. This problem has become a common pain point restricting the stable operation of the automatic feeding device for recycled materials.

[0003] To address the problem of hopper blockage, Chinese Patent No. CN222768803U discloses an automatic feeding device for color masterbatch, plastic particles, and recycled materials. This device optimizes the feeding smoothness by incorporating an anti-blocking mechanism: after the recycled material is placed into the hopper, starting the first motor drives the circular roller to rotate on the inner wall of the circular hole frame. Through belt transmission, the roller further drives two impeller rods to rotate at the hopper outlet, keeping the recycled material in motion at the outlet. This effectively avoids blockage and ensures that the recycled material is evenly fed into the automatic feeding hopper rod, thus improving feeding efficiency to a certain extent and providing technical support for the smooth transport of recycled materials.

[0004] However, existing automatic feeding devices for recycled materials, including this patented solution, still have significant defects and shortcomings in practical applications. The core problem lies in their relatively simple overall structure, lacking a stirring structure specifically for plastic particles and color masterbatch. This prevents the two from being mixed before feeding, leading to various issues. Plastic particles and color masterbatch rely on subsequent processing equipment (such as extruders and injection molding machines) for mixing, but the core function of these machines is material melting and molding. The contact time between the two within the equipment is short, and the mixing space is limited, making it difficult to achieve uniform dispersion of the color masterbatch. This easily results in color spots and streaks on the surface of the final product, failing to meet product color uniformity standards. Simultaneously, the differences in particle size and density between plastic particles and color masterbatch lead to stratification during transport without pre-mixing. This results in significant fluctuations in the proportion of materials entering the processing equipment at different times, exacerbating color instability. Furthermore, the content of toughening agents, antioxidants, and other additives in the color masterbatch fluctuates with the proportion, causing significant differences in the product's mechanical properties and weather resistance, making it impossible to achieve uniform performance indicators. Without pre-mixing, the color masterbatch... Directly feeding recycled materials into the processing equipment can lead to uneven flowability of the molten material due to excessively high local concentrations. Areas with high masterbatch concentrations exhibit increased melt viscosity, easily creating dead zones where material stagnates. These dead zones reduce material conveying speed and may cause overheating and degradation due to prolonged material retention. The resulting impurities can clog equipment channels, increasing cleaning frequency and maintenance costs, while also reducing production efficiency. For masterbatches containing functional additives such as antistatic agents and flame retardants, existing devices lack a stirring structure, preventing pre-mixing of additives and plastic particles. Additives are simply dispersed within the processing equipment, easily resulting in insufficient additive content in certain areas, causing partial loss of corresponding functions and failing to meet diverse performance requirements. In summary, while existing automatic recycled material feeding devices solve the feeding blockage problem, the lack of stirring and mixing functions still presents significant shortcomings in processing quality, performance stability, production efficiency, and functional expansion, failing to meet the demands of modern plastics processing for high-quality, high-stability production. Therefore, optimization and improvement of the device structure are urgently needed. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes an automatic mixing and feeding machine for plastic particle color masterbatch, which can more accurately solve the problems described above.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes an automatic mixing and feeding machine for plastic particle masterbatch, including a base, an angle adjustment mechanism fixedly installed on the top of the base, a screw feeding mechanism movably installed on the inner side of the angle adjustment mechanism, a fixed frame fixedly installed on the top of the base away from the screw feeding mechanism, a mixing mechanism fixedly installed on the upper end of the fixed frame, and the output end of the mixing mechanism and the input end of the screw feeding mechanism are connected.

[0008] The angle adjustment mechanism includes a hinge seat, which is fixedly installed on the top of the base. A rotating shaft is rotatably connected to the upper inner end of the hinge seat. The screw feeding mechanism is fixedly installed in the middle of the rotating shaft. An adjustment module is fixedly installed on the front end of the base away from the mixing mechanism.

[0009] Furthermore, the adjustment module includes a turntable and a side plate. The turntable is rotatably connected to the upper front end of the hinge base. The side plate is fixedly installed on the front side of one side of the base. A lower hinge frame is fixedly installed on the top of the side plate. A connecting rod is fixedly installed on the front of the turntable. An upper hinge frame is fixedly installed on the outer end of the connecting rod. An electric push rod is hinged between the inner sides of the lower hinge frame and the upper hinge frame. The back of the turntable is connected to the front end of the rotating shaft.

[0010] Furthermore, mounting holes are provided at the four corners of the top of the base, and the mounting holes are countersunk holes.

[0011] Furthermore, the spiral feeding mechanism includes a feeding pipe, which is fixedly installed in the middle of the rotating shaft. A first motor is fixedly installed at the bottom end of the feeding pipe, and a conveying auger is fixedly installed through the output end of the first motor through the feeding pipe. The conveying auger is rotatably connected to the inside of the feeding pipe.

[0012] Furthermore, the mixing mechanism includes a tank body, which is fixedly installed on the upper end of a fixed frame. A sealing cover is bolted to the top of the tank body. A stirring module is provided in the middle of the sealing cover. The lower end of the stirring module is rotatably connected to the inside of the tank body. A discharge hopper is fixedly installed at the bottom output end of the tank body. A discharge valve is fixedly installed at the bottom of the discharge hopper. The output end of the discharge valve and the input end of the feeding pipe are connected through a flexible hose. A feed valve is fixedly connected to one side of the top of the sealing cover.

[0013] Furthermore, a feed guide hopper is fixedly installed on the top of the feed valve, and an extension guide hopper is fixedly installed on the top of the feed guide hopper. Both the feed guide hopper and the extension guide hopper have conical side shapes.

[0014] Furthermore, the stirring module includes a second motor, which is fixedly installed in the middle of the top of the sealing cover. The output end of the second motor is fixedly installed with a stirring shaft through the sealing cover. Stirring plates are fixedly installed in a ring at equal intervals on the upper surface of the stirring shaft. A conical spiral stirring auger is fixedly installed at the lower end of the stirring shaft. The outer surface of the conical spiral stirring auger is in close contact with the inner wall of the discharge hopper.

[0015] The beneficial effects of this utility model are:

[0016] 1. During the application of this technical solution, by setting up a mixing mechanism and a hose, the conical spiral agitator in the mixing mechanism can drive the material upward to roll, enhancing the uniformity of material mixing. The downward drive can assist in pushing the material to the discharge position. Together with the hose, it can achieve stable material conveying. The feeding-related structure of the mixing mechanism guides the material to enter in a concentrated manner, so that the plastic particles and color masterbatch can be fully mixed before feeding during use, avoiding material scattering and insufficient mixing. This ensures that the mixed material enters the subsequent feeding stage evenly, thereby improving the uniformity of material mixing and ensuring smooth material conveying. It solves the problems in the existing technology that the lack of a mixing structure leads to uneven dispersion of color masterbatch, the appearance of "color spots" and "color streaks", as well as easy blockage of material conveying, large ratio fluctuations, and inconsistent mechanical properties and weather resistance of products.

[0017] 2. During the application of this technical solution, by setting up an angle adjustment mechanism and a screw feeding mechanism, the electric push rod in the angle adjustment mechanism can extend and retract to drive the rotation of related components, thereby adjusting the angle of the feeding pipe. The screw feeding mechanism can continuously push materials to avoid accumulation, so that the feeding angle can be flexibly adjusted according to the inlet height of the subsequent processing equipment during use, ensuring accurate docking of the feeding pipe outlet end, and realizing stable conveying of mixed materials. This achieves the effect of improving the adaptability of the device to different scenarios, ensuring conveying efficiency and equipment life, and solving the problems of fixed feeding angle that cannot be adapted to different equipment, easy blockage of material conveying, large load changes of equipment due to material ratio fluctuations, high maintenance costs, and low production efficiency in the existing technology, thus meeting the high-quality production needs of modern plastic processing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] An automatic mixing and feeding machine for plastic particle masterbatch includes a base 1, an angle adjustment mechanism 2 fixedly installed on the top of the base 1, a screw feeding mechanism 3 movably installed on the inner side of the angle adjustment mechanism 2, a fixed frame 4 fixedly installed on the top of the base 1 away from the screw feeding mechanism 3, a mixing mechanism 5 fixedly installed on the upper end of the fixed frame 4, and the output end of the mixing mechanism 5 is connected to the input end of the screw feeding mechanism 3.

[0027] The angle adjustment mechanism 2 includes a hinge seat 21, which is fixedly installed on the top of the base 1. A rotating shaft 22 is rotatably connected to the upper end of the hinge seat 21. A screw feeding mechanism 3 is fixedly installed in the middle of the rotating shaft 22. An adjustment module 23 is fixedly installed on the front end of the base 1 on the side away from the mixing mechanism 5. When this automatic plastic particle and color masterbatch mixing and feeding machine is used, the plastic particles and color masterbatch are first mixed by the mixing mechanism 5 at the upper end of the fixed frame 4 on the top of the base 1. After the mixing mechanism 5 completes the mixing, its output end conveys the mixed material to the input end of the screw feeding mechanism 3, which is connected to it. The angle adjustment mechanism 2 on the top of the base 1 can adjust the angle of the screw feeding mechanism 3 according to the height of the feed inlet of the subsequent processing equipment. The hinge seat 21 of the angle adjustment mechanism 2 provides rotational support for the rotating shaft 22. The screw feeding mechanism 3 is fixed in the middle of the rotating shaft 22. When the angle needs to be adjusted, the adjustment module 23 at the front end of the base 1 away from the mixing mechanism 5 is activated. The adjustment module 23 drives the rotating shaft 22 to rotate inside the upper end of the hinge seat 21. The rotating shaft 22 simultaneously drives the screw feeding mechanism 3 to adjust to the appropriate angle. After the angle adjustment is completed, the screw feeding mechanism 3 is activated to stably transport the mixed material from the mixing mechanism 5 to the subsequent processing equipment. Throughout the process, the base 1 provides a stable installation foundation for the angle adjustment mechanism 2, the fixing frame 4 and other components, ensuring that each mechanism works together to complete the mixing and feeding of plastic particles and masterbatch.

[0028] Combination Figures 1-4 As shown, the adjustment module 23 includes a turntable 231 and a side plate 232. The turntable 231 is rotatably connected to the upper front end of the hinge base 21. The side plate 232 is fixedly installed on the front end of one side of the base 1. A lower hinge frame 233 is fixedly installed on the top of the side plate 232. A connecting rod 234 is fixedly installed on the front of the turntable 231. An upper hinge frame 235 is fixedly installed on the outer end of the connecting rod 234. An electric push rod 2 is hinged between the inner sides of the lower hinge frame 233 and the upper hinge frame 235. 36. The back of the turntable 231 is connected to the front end of the rotating shaft 22. Mounting holes 6 are provided at the four corners of the top of the base 1. The mounting holes 6 are countersunk holes. The spiral feeding mechanism 3 includes a feeding pipe 31. The feeding pipe 31 is fixedly installed in the middle of the rotating shaft 22. A first motor 32 is fixedly installed at the bottom end of the feeding pipe 31. The output end of the first motor 32 passes through the feeding pipe 31 and a conveying auger 33 is fixedly installed. The conveying auger 33 is rotatably connected to the inside of the feeding pipe 31.

[0029] In the above-described embodiments of this application, during the application of this device, it is first fixed through the mounting holes 6 at the four corners of the top of the base 1. The mounting holes 6 are countersunk holes, which allow the heads of the mounting bolts to be embedded in the holes, avoiding the bolt heads protruding and interfering with surrounding operations or equipment, thus providing a stable foundation for the overall operation of the device. When it is necessary to adjust the angle of the screw feeding mechanism 3 to adapt to the subsequent processing equipment, the electric push rod 236 of the adjustment module 23 is activated. When the electric push rod 236 extends and retracts, it will drive the lower hinge frame 233 and the upper hinge frame 235, which are respectively hinged at both ends, to move relative to each other. The upper hinge frame 235 drives the turntable 231 to rotate on the upper front of the hinge seat 21 through the connecting rod 234. Since the back of the turntable 231 is connected to the front end of the rotating shaft 22, the rotation of the turntable 231 synchronously drives the rotating shaft 22 to rotate, thereby enabling the screw feeding mechanism fixed in the middle of the rotating shaft 22 to rotate. Mechanism 3 is adjusted to a suitable angle, allowing for flexible adaptation to feed inlets of different heights without disassembling base 1. This reduces equipment adjustment time and improves scenario adaptability. After the angle is adjusted, the screw feeding mechanism 3 is activated. The output end of the first motor 32 at the bottom of the feeding pipe 31 drives the conveying auger 33 to rotate inside the feeding pipe 31. When the conveying auger 33 rotates, it generates a continuous pushing force on the mixed material inside the pipe, smoothly conveying the material from the input end to the output end of the feeding pipe 31, avoiding material accumulation and blockage inside the pipe, and ensuring conveying efficiency. At the same time, the stable rotation of the conveying auger 33 ensures uniform material conveying speed, avoiding load changes in subsequent processing equipment due to material conveying fluctuations, and extending the service life of the equipment. The entire process achieves precise angle adjustment and stable material conveying through the coordinated operation of various components, further improving the reliability and practicality of the device operation.

[0030] Example 2

[0031] Combination Figures 1-5As shown, the mixing mechanism 5 includes a tank 51, which is fixedly installed on the upper end of the fixing frame 4. A sealing cover 52 is bolted to the top of the tank 51. A stirring module 56 is provided in the middle of the sealing cover 52. The lower end of the stirring module 56 is rotatably connected to the inside of the tank 51. A discharge hopper 54 is fixedly installed at the bottom output end of the tank 51. A discharge valve 55 is fixedly installed at the bottom of the discharge hopper 54. The output end of the discharge valve 55 and the input end of the feeding pipe 31 are connected through a flexible hose. A feed valve 53 is fixedly connected to one side of the top of the sealing cover 52. A feed guide hopper 57 is fixedly installed on the top of the feed valve 53. An extended guide hopper 58 is fixedly installed on the top of the guide hopper 57. Both the feed guide hopper 57 and the extended guide hopper 58 have conical side shapes. The stirring module 56 includes a second motor 561, which is fixedly installed in the middle of the top of the sealing cover 52. The output end of the second motor 561 passes through the sealing cover 52 and is fixedly installed with a stirring shaft 562. Stirring plates 563 are fixedly installed in a ring at equal intervals on the upper surface of the outer surface of the stirring shaft 562. A conical spiral stirring auger 564 is fixedly installed at the lower end of the stirring shaft 562. The outer surface of the conical spiral stirring auger 564 is in close contact with the inner wall of the discharge hopper 54.

[0032] In the above-described embodiments of this application, during the application of this device, when mixing plastic particles and color masterbatch, the feed valve 53 on one side of the top of the sealing cover 52 is first opened, and the plastic particles and color masterbatch are poured into the tank 51 through the feed guide hopper 57 and the extended guide hopper 58. The sides of the feed guide hopper 57 and the extended guide hopper 58 are both cone-shaped, which can guide the material to concentrate into the tank 51, avoid the material from scattering in all directions during the pouring process, reduce material waste, and reduce the probability of external impurities mixing in, ensuring the initial purity of the material. After the material is poured in, the second motor 561 of the stirring module 56 is started. The output end of the second motor 561 drives the stirring shaft 562 that penetrates the sealing cover 52 to rotate inside the tank 51. The stirring plate 563 on the upper part of the outer surface of the stirring shaft 562 rotates synchronously with the stirring shaft 562, which fully stirs and disperses the material in the upper part of the tank 51, breaks up the material agglomeration, and makes the plastic particles... The mixture is initially mixed with the color masterbatch. The conical spiral agitator 564 at the lower end of the agitator shaft 562 rotates synchronously, and its outer surface is in contact with the inner wall of the discharge hopper 54. This not only agitates the material at the bottom of the tank 51, further improving the uniformity of the mixture, but also generates a downward pushing force on the mixed material during rotation, preventing the material from accumulating at the bottom of the tank 51. After the material is mixed, the discharge valve 55 at the bottom of the discharge hopper 54 is opened. Under the pushing action of the conical spiral agitator 564, the mixed material is stably conveyed to the input end of the feed pipe 31 through the hose. The hose can be adjusted to accommodate subsequent angle adjustments of the feed pipe 31, ensuring that the material conveying is not affected by angle changes. Throughout the process, the sealing cover 52 is bolted to the top of the tank 51, which can effectively prevent material dust from spilling out during the mixing process, ensuring a clean working environment. At the same time, it provides a stable installation foundation for the agitator module 56, ensuring that the mixing and blending operation is carried out efficiently and orderly.

[0033] The working principle and advantages of this utility model are as follows: When using this device, the first step is to fix the equipment. The base 1 has countersunk mounting holes 6 at its four corners. These holes allow the entire device to be fixed in the designated plastic processing area. The countersunk hole design prevents the heads of the mounting bolts from protruding, thus preventing interference with surrounding operations or equipment and providing a stable foundation for all subsequent operations. The fixing frame 4 supports the tank 51 of the mixing mechanism 5, ensuring that the tank 51 does not wobble during the mixing process. The rotating shaft 22 of the angle adjustment mechanism 2 provides installation and rotation support for the feeding pipe 31 of the screw feeding mechanism 3. This structural layout ensures stable assembly of all core components of the device. To avoid affecting operational accuracy due to loose components and to address the issue of insufficient overall stability in existing devices, after fixing, the mixing mechanism 5 is activated to mix plastic particles and color masterbatch. The operator opens the feed valve 53 on one side of the top of the sealing cover 52, and pours the plastic particles and color masterbatch into the tank 51 through the feed guide hopper 57 and the extended guide hopper 58. Both the feed guide hopper 57 and the extended guide hopper 58 have conical sides, which guides the material to concentrate in the tank 51, preventing material from scattering and causing waste. Then, the sealing cover 52 is closed and fixed with bolts. The sealing cover 52 prevents material dust from overflowing during the mixing process, ensuring a clean working environment, and at the same time provides a stable installation foundation for the mixing module 56. The mixing module 5 is then activated. The second motor 561 of unit 6 drives the stirring shaft 562 to rotate inside the tank 51. The stirring plate 563 on the upper part of the outer surface of the stirring shaft 562 initially stirs and disperses the material in the upper part of the tank 51. The conical spiral stirring auger 564 at the lower end of the stirring shaft 562 rotates synchronously: when the conical spiral stirring auger 564 rotates in the forward direction, it drives the material upward to roll, further enhancing the mixing uniformity of the material in the tank 51 and avoiding insufficient mixing in some areas; when it is necessary to discharge the material, the conical spiral stirring auger 564 drives downward to assist in pushing the material, causing the mixed material to move stably towards the discharge hopper 54, which, combined with its outer surface fitting against the inner wall of the discharge hopper 54, makes it suitable for this purpose. To ensure that the material does not accumulate in the discharge hopper 54, after mixing is completed, the discharge valve 55 at the bottom of the discharge hopper 54 is opened. Under the pushing action of the conical spiral agitator 564, the mixed material is smoothly conveyed through the hose to the feeding pipe 31 of the spiral feeding mechanism 3. The hose can be adapted to the subsequent angle adjustment of the feeding pipe 31 to ensure that the material conveying is not affected by the angle change. This technical solution completes the mixing before feeding, so that the material has formed a uniform mixture before entering the subsequent processing equipment. This avoids the problems of uneven dispersion of color masterbatch, color spots and streaks caused by the lack of a stirring structure in the existing device. At the same time, it prevents the material ratio fluctuation caused by layered conveying, ensures the stability of the additive content in the color masterbatch, and ensures the consistency of the product's mechanical properties and weather resistance.

[0034] Next, based on the height of the feed inlet of the subsequent processing equipment, the feeding angle of the screw feeding mechanism 3 is adjusted via the angle adjustment mechanism 2. The electric push rod 236 of the adjustment module 23 is activated. When the electric push rod 236 extends or retracts, it pushes the upper hinge frame 235, causing the connecting rod 234 and the turntable 231 to rotate. The turntable 231 then drives the rotating shaft 22 to rotate synchronously. The rotating shaft 22 then drives the feeding pipe 31 to adjust its angle until the discharge end of the feeding pipe 31 is precisely aligned with the feed inlet of the subsequent processing equipment. During this process, the operator can observe the rotation of the turntable 231 to judge the angle adjustment range and ensure accurate adjustment. Compared with the existing devices where the feeding barrel rod is fixed and cannot adapt to different height feed inlets, this device can flexibly adjust the feeding angle without disassembling and reinstalling the base 1, significantly improving adaptability to different processing scenarios, reducing equipment adjustment time, and further improving overall production efficiency. Finally, the screw feeding mechanism 3 is activated to convey the mixed materials. The bottom of the feeding pipe 31 of the screw feeding mechanism 3 is fixed with a first motor 32. After the first motor 32 is started, its… The output end drives the conveying auger 33 to rotate inside the feeding pipe 31. When the conveying auger 33 rotates, it generates a continuous pushing force on the mixed material inside the feeding pipe 31, smoothly conveying the material from the input end of the feeding pipe 31 to the output end, and finally into the subsequent processing equipment, completing the entire mixing and feeding process. The design of the conveying auger 33 can avoid the accumulation and blockage of material in the feeding pipe 31. Compared with the existing devices that only use impeller rods to prevent blockage, this device conveys more stably and efficiently. At the same time, since the mixed material has been pre-mixed evenly, it will not cause uneven flow of molten material due to excessive local concentration of color masterbatch after entering the subsequent processing equipment. It can effectively avoid the formation of dead corners in the equipment, reduce the problem of material overheating degradation and flow channel blockage, reduce the frequency of equipment cleaning and maintenance costs, and extend the service life of the equipment. In addition, through the coordinated work of various core components, this device realizes the integrated operation from mixing to angle adjustment to conveying. Compared with the shortcomings of the single function of the existing device, this technical solution integrates multiple core functions and fully meets the needs of modern plastic processing for high-quality and high-stability production.

[0035] In this technical solution, the lead screw is made of AISI 4140 chromium-molybdenum alloy steel, with a tensile strength of 95-107.3 kSi, a yield strength of 60.2-95 kSi, and an elongation of 17.7-25.7%, suitable for long-term use in air or water. The gear is made of 17201 (12CrMo4) chromium-molybdenum alloy steel, with a tensile strength ≥947 MPa, a yield strength ≥715 MPa, an elongation ≥14%, a reduction of area ≥12%, and a Brinell hardness (HBW) ≤207. This material ensures stable operation in air or water. The lead screw and gear are lubricated with polytetrafluoroethylene lubricating oil containing special additives, allowing for long-term use in air and water. To maintain lubrication, in terms of electronic components, the first motor 32 is a Y90L-2 motor with a rated power of 2.2kW and a rated voltage of 380V; the second motor 561 is a Y112M-4 motor with a rated power of 4kW and a rated voltage of 380V. The controller is a Siemens S7-200SMART series PLC, which is installed in a specially set electrical control box on the side of the base 1. It is connected to the first motor 32 and the second motor 561 through wires and is powered by 380V three-phase AC power. The internal programming logic controls the start, stop, and speed adjustment of the motors to achieve precise control of the mixing mechanism 5 and the screw feeding mechanism 3.

[0036] The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.

[0037] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
