Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic processing technology, and in particular to a color matching and granulation machine for processing plastic masterbatch. Background Technology
[0002] With the booming development of the plastics industry, plastic products are increasingly widely used in many fields such as daily life, industrial production, and packaging. Consumers' requirements for the color of plastic products are also becoming more and more diversified. They not only require rich colors, but also uniform, stable colors and good durability. Plastic masterbatch, as a highly efficient colorant, has emerged. It can accurately provide the required color for plastic products. Granulators are the key equipment for producing high-quality masterbatch. Among them, single-screw extrusion color matching granulator stands out with its relatively simple structure.
[0003] A single-screw extruder typically consists of a feed inlet, heating zone, screw, barrel, and die. Its working principle relies on the rotational motion of the screw to push and heat the raw material to a molten state. At the same time, it completes the mixing, extrusion, and granulation of the material through external heating and internal friction temperature rise.
[0004] Currently, traditional single-screw extrusion color matching and granulation machines have a relatively simple design and generally lack a pretreatment stage. This results in raw materials entering the extruder without screening, which can lead to a series of adverse consequences. First, larger particles or impurities in the raw materials may interfere with the normal flow of the material after entering the extruder. Second, unscreened raw materials are prone to uneven mixing. When different plastic raw materials are not effectively screened, large particles of impurities will hinder sufficient contact between the raw materials. Pigment particles may not be evenly dispersed in the carrier resin due to the obstruction of large particles of impurities, thus affecting the uniform distribution of color. At the same time, due to the different particle sizes, unscreened raw materials cannot achieve the same preheating effect as other smaller particles of raw materials in a short time during the preheating stage. This results in uneven temperature of the entire material when it enters the extruder. This uneven temperature will further affect the plasticization quality of the material, preventing the material from fully blending together during the extrusion process. This will not only affect the quality and appearance of the product, but also increase production costs and reduce production efficiency. Therefore, a color matching and granulation machine for processing plastic masterbatch is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a color matching granulator for processing plastic masterbatch, aiming to improve the problem that the design of the traditional single-screw extrusion color matching granulator in the prior art is relatively simple and lacks pre-treatment screening function, which leads to a reduction in granulation quality and efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A color matching and granulation machine for processing plastic masterbatch includes a base and a collection bin. A cylinder is assembled between the base and the collection bin. A motor is assembled at one end of the cylinder near the base. A screw is fixedly connected to the output end of the motor. A die head is assembled at one end of the screw near the collection bin. A hopper is assembled at the top of the base. A screening component is arranged inside the hopper. A discharge port is assembled between the cylinder and the hopper. A cooling component is arranged in the middle of the collection bin. A collection component is arranged at the bottom of the screening component.
[0008] The screening assembly includes a second motor, which is fixedly connected to the side of the hopper away from the discharge port. An eccentric wheel is fixedly connected to the output end of the second motor, and a screen is provided inside the hopper.
[0009] As a further description of the above technical solution:
[0010] The cooling component includes a fan, which is mounted in the middle of the collection chamber. The collection chamber is provided with heat sinks, heat dissipation rings, and heat dissipation holes.
[0011] As a further description of the above technical solution:
[0012] The collection assembly includes a collection box, which is slidably connected to the middle of the hopper, and a pull ring is fixedly connected to the outside of the collection assembly;
[0013] As a further description of the above technical solution:
[0014] The bottom of the screen has multiple spring rods evenly distributed, and the eccentric wheel abuts against the side of the screen near the spring rods.
[0015] As a further description of the above technical solution:
[0016] A heating block is provided at the bottom of the screw, and a collection vehicle is slidably connected to the bottom of the collection chamber;
[0017] As a further description of the above technical solution:
[0018] The hopper is equipped with a fixing rod inside, and the fixing rod is rotatably connected to the end of the screen away from the motor.
[0019] As a further description of the above technical solution:
[0020] The output end of the fan is adapted to the position of the heat dissipation hole;
[0021] As a further description of the above technical solution:
[0022] The heat dissipation ring is assembled on the outside of the heat dissipation hole, and the heat dissipation fins are evenly distributed on the outside of the heat dissipation ring.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the eccentric wheel is driven by a motor to rotate. The eccentric wheel contacts the screen periodically, causing the screen to move up and down regularly at a specific frequency with the assistance of a spring rod. This screens out various raw materials with uniform particle size. After being effectively vibrated and screened by the screen, these raw materials fall smoothly into the machine barrel through the discharge port. Smaller dust and debris fall into the collection box. This method effectively improves the overall quality level of the raw materials and prevents processing defects such as incomplete plasticization, mottled product color, and different particle shapes caused by uneven raw material particles or impurities. It significantly improves the stability of the production process and the reliability of product quality of the color matching granulator used for color masterbatch processing.
[0025] 2. In this utility model, the fan blows out flowing air, which quickly comes into contact with the surface of the particles, efficiently carrying away the heat in the particles. The heat is then transferred to the heat sink, which quickly conducts the heat to the heat dissipation ring that is closely connected to it, and finally dissipates it into the surrounding environment through the heat dissipation holes. This effectively prevents the particles from sticking or deforming due to slow cooling, ensuring the molding quality and appearance integrity of the particles, and greatly improving the product qualification rate and production efficiency.

[0032] 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.
[0033] Reference Figure 4 This utility model provides an embodiment of a color matching and granulation machine for processing plastic masterbatch, including a base 1 and a collection bin 2. A cylinder 3 is assembled between the base 1 and the collection bin 2. A motor 4 is assembled at one end of the cylinder 3 near the base 1. A screw 5 is fixedly connected to the output end of the motor 4. The screw 5 is driven to rotate by the motor 4 to realize the effective pushing, shearing, heating, and granulation of the raw materials inside the cylinder 3. A die head 6 is assembled at one end of the screw 5 near the collection bin 2. Different sizes of granules can be produced by changing the die head 6. A hopper 8 is assembled at the top of the base 1. A screening component 10 is set inside the hopper 8. A discharge port 9 is assembled between the cylinder 3 and the hopper 8. The screened material is conveyed to the cylinder 3 under the action of gravity through the discharge port 9. A cooling component 19 is set in the middle of the collection bin 2. A collection component 16 is set at the bottom of the screening component 10.
[0034] The screening assembly 10 includes a second motor 11, which is fixedly connected to the side of the hopper 8 away from the discharge port 9. An eccentric wheel 12 is fixedly connected to the output end of the second motor 11. A screen 13 is installed inside the hopper 8. Multiple spring rods 15 are evenly distributed at the bottom of the screen 13. The eccentric wheel 12 abuts against the side of the screen 13 near the spring rods 15. The second motor 11 drives the eccentric wheel 12 to rotate continuously. The eccentric wheel 12 contacts the screen 13 periodically, causing the screen 13 to generate force that is transmitted to the bottom spring rods 15. The spring rods 15 then extend and vibrate, thereby driving the screen 13 to achieve a stable up-and-down regular movement. During this process, raw material particles of different sizes are separated on the screen 13 according to the screen hole size, successfully screening out various raw materials with uniform particle size. These precisely screened raw materials fall smoothly into the barrel 3 through the discharge port 9, ensuring the consistency of raw material quality in subsequent processing stages. Smaller dust and debris, unable to pass through the screen, fall into the collection box 17 for proper handling later.
[0035] This method effectively solves the problem of uneven dispersion during mixing and plasticizing processes caused by uneven particle size of raw materials. It significantly improves the mixing uniformity of materials in barrel 3, laying a solid foundation for producing high-quality products with uniform color and stable physical properties. It reduces the defect rate caused by uneven raw materials and improves the overall production efficiency and product quality stability of the color matching granulator for plastic masterbatch processing.
[0036] Reference Figure 2 and Figure 3 The cooling component 19 includes a fan 20, which is mounted in the middle of the collection chamber 2. The collection chamber 2 is equipped with a heat sink 21, a heat dissipation ring 22 and heat dissipation holes 23. The fan 20 blows out a stable airflow, which comes into full contact with the freshly produced particles. The heat contained inside the particles is efficiently carried away by the air convection. The heat carried away is then conducted to the heat sink 21. The heat sink 21, with its special material and large contact area, causes the heat to be quickly transferred to the heat dissipation ring 22 that is in close contact with it. Finally, the heat is quickly dissipated to the surrounding environment through the heat dissipation holes 23.
[0037] This synergistic heat dissipation mechanism can precisely and efficiently control the cooling process of the granules, effectively avoiding problems such as adhesion, deformation, or internal structural deterioration caused by residual heat retention. It strongly guarantees the morphological integrity and internal quality stability of the granules, thus providing good material conditions for subsequent packaging, transportation, and further processing. This greatly improves the reliability of the entire production process and the controllability of product quality of the color matching granulator used for plastic masterbatch processing.
[0038] Reference Figures 1-4 The collection component 16 includes a collection box 17, which is slidably connected to the middle of the hopper 8. A pull ring 18 is fixedly connected to the outside of the collection component 16. The collection box 17 can be quickly pulled out and the dust and debris inside can be cleaned through the pull ring 18, which effectively improves the cleaning efficiency. A heating block 24 is provided at the bottom of the screw 5. A collection cart 25 is slidably connected to the bottom of the collection chamber 2. The heating block 24 is used to preheat the mixed raw materials, which improves the granulation quality and granulation efficiency. A fixing rod 14 is provided inside the hopper 8. The fixing rod 14 is rotatably connected to the end of the screen 13 away from the motor 11. The fixing rod 14 drives one end of the screen 13 to rotate, which ensures that the other end of the screen 13 can move up and down effectively, so that the screen 13 has a slope structure, which effectively increases the rate at which the raw materials enter the discharge port 9 and improves the discharge efficiency. The output end of the fan 20 is matched with the position of the heat dissipation hole 23. The heat dissipation ring 22 is assembled on the outside of the heat dissipation hole 23, and the heat dissipation fins 21 are evenly distributed on the outside of the heat dissipation ring 22.
[0039] Working principle: First, the masterbatch and other raw materials are placed into the hopper 8. The second motor 11 is started, which drives the eccentric wheel 12 to rotate. The eccentric wheel 12 makes periodic contact with the screen 13, so that the screen 13 moves up and down in a regular manner. Various raw materials with uniform particle size are screened out and fall into the barrel 3 through the discharge port 9 after being screened by the screen 13. Smaller dust and debris fall into the collection box 17 for further processing. This method solves the problem of uneven mixing of raw material particles. Then, the first motor 4 is started, which drives the screw 5 to rotate. This drives the raw materials with uniform particle size to be heated by the heating block 24 and then granulated by the die head 6. The particles granulated by the die head 6 fall into the collection cart 25. At this time, the fan 20 is started. The fan 20 blows out flowing air to take away the heat in the particles. The heat is transferred to the heat sink 21. The heat in the heat sink 21 is quickly transferred to the heat dissipation ring 22 and quickly discharged through the heat dissipation hole 23, which quickly reduces the temperature of the produced particles.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
