Description

Technical Field

[0001] This invention relates to the field of plastic parts processing technology, and more particularly to plastic extrusion equipment for processing plastic parts. Background Technology

[0002] Plastic extrusion equipment is an industrial machine used to produce continuous plastic products. Through processes such as heating, melting, extrusion, and shaping, plastic raw materials are processed into products such as pipes, sheets, films, and profiles. The shearing force and pressure generated by the screw rotation make the plastic uniformly plasticized and formed by molds. This equipment is widely used in fields such as construction, packaging, automotive parts manufacturing, and cable sheathing. It has the advantages of high efficiency, continuous production, and low cost, and is a key piece of equipment in the plastic processing industry.

[0003] Traditional plastic extrusion equipment for plastic parts processing is prone to clogging due to a lack of anti-clogging design and uneven heating. This causes raw materials to easily accumulate into lumps or bridge, resulting in discontinuous material conveying into the extrusion section. Consequently, it affects the heating time and shearing effect of the plastic in the heating cylinder. Some areas experience delayed melting due to excessive material accumulation, while the cavity area overheats due to insufficient material, creating a vicious cycle. Similarly, when the equipment's heating capacity is insufficient, localized overheating of the cylinder can cause viscous materials to soften prematurely and adhere to the connection between the hopper and the cylinder, further hindering material flow. Meanwhile, in low-temperature areas, insufficient melting forms hard lumps, increasing screw propulsion resistance and amplifying the clogging problem. This necessitates repeated adjustments to temperature and screw speed, and even machine shutdowns for manual unblocking, completely disrupting the production rhythm and causing a loss of production quality control.

[0004] Therefore, in response to the problems of clogging, disrupting production rhythm, reducing production quality, and increasing energy consumption in traditional plastic extrusion equipment for processing plastic parts, a plastic extrusion equipment for processing plastic parts that can prevent clogging and provide uniform heating can be designed.

[0017] The beneficial effects of this invention are:

[0018] 1. The anti-clogging component drives the stirring scraper to rotate, which can not only break up the clumps of raw materials, but also continuously scrape the bucket wall to prevent material adhesion and accumulation. This effectively prevents raw materials from bridging or clumping, allowing plastic granules to fall evenly.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] As the core equipment in the plastics processing industry, the working principle and performance of plastic extrusion equipment directly determine the quality and production efficiency of the final product. This type of equipment transforms solid plastic raw materials into continuous products with specific shapes and properties through the synergistic effect of mechanical force and thermal energy. The entire processing involves the precise coordination of multiple key links.

[0030] From the perspective of equipment structure, a typical plastic extrusion equipment mainly consists of a transmission system, an extrusion system, a heating and cooling system, a control system, and auxiliary equipment. Among them, the extrusion system is the core component, including key components such as the screw, barrel, hopper, and die. The screw, as the "heart component," directly affects the plasticizing effect and extrusion pressure of the material due to its geometric parameters and rotational speed. The barrel undertakes the important functions of heating and heat preservation, and usually has multiple temperature control zones inside. The hopper, as the raw material inlet, has a design rationality that directly affects the stability of subsequent processes.

[0031] In terms of working principle, plastic extrusion is a complex physicochemical process. Solid plastic granules first enter the barrel through the hopper and are conveyed forward by the rotation of the screw. During this process, the material goes through three key stages: first, the solid conveying section, where the material remains solid but is gradually compacted; second, the melting section, where the material begins to soften and melt under the combined action of shear heat and external heating; and finally, the homogenization section, which ensures that the melt temperature is uniform and establishes a stable extrusion pressure. Ultimately, the uniformly plasticized melt is formed through a mold and, after cooling and solidification, the desired product is obtained.

[0032] However, traditional plastic extrusion equipment often faces many technical bottlenecks in actual operation. These problems are often interconnected and form a vicious cycle. Among them, the clogging problem of the feeding system is particularly prominent. Due to the lack of effective anti-clogging design, when processing plastic raw materials with a certain degree of viscosity, such as PVC and TPU, it is very easy to form a "bridging" phenomenon inside the hopper. This bridging will cause the raw material flow to be interrupted, making the material entering the extrusion section intermittent. More seriously, for some composite raw materials with high additive content, such as plastics containing a large amount of fillers or reinforcing fibers, the flowability is even worse, further increasing the risk of clogging.

[0033] This blockage problem triggers a series of chain reactions. When material conveying is discontinuous, the filling state of each section of the screw fluctuates. In the solid conveying section, excessive material accumulation can lead to increased local pressure, increasing the load on the drive motor. In the melting section, uneven material distribution can cause a decrease in heat transfer efficiency. Some areas experience delayed melting due to material accumulation, while adjacent areas overheat due to material shortage. This uneven thermal field distribution can in turn exacerbate the blockage problem, as the material in the overheated area may soften prematurely and adhere to the inner wall of the barrel. Meanwhile, hard lumps in the low-temperature area increase the screw's propulsion resistance.

[0034] The imperfections in the heating system further amplify these problems. Traditional equipment often uses electric heating coils for direct heating, which has obvious limitations. On the one hand, the heat conduction of electric heating coils is directional, resulting in uneven temperature distribution around the barrel. On the other hand, static heating methods cannot quickly respond to changes in the material flow state. When a local area needs more heat due to material accumulation, the traditional heating system cannot provide enough heat energy in time. In areas with material shortage, continuous heating will lead to overheating. This lack of thermal management capability makes it difficult to maintain a stable plasticizing process for the material.

[0035] The continued existence of these problems can seriously affect the production process. Operators have to frequently adjust process parameters, such as increasing the screw speed to deal with blockages or modifying temperature settings to compensate for uneven heating. Such passive adjustments are often only temporary solutions and may even cause new problems. For example, while increasing the speed can temporarily relieve blockages, it will exacerbate shear heat generation, which may lead to thermal degradation of the material. Frequent changes in temperature settings will affect the thermal balance of the entire system. Ultimately, the stability of the production line is completely destroyed, and it is necessary to shut down the machine for manual cleaning and maintenance.

[0036] From a product quality perspective, the consequences of these problems are equally serious. Uneven melt will first affect the dimensional stability of the product, such as uneven wall thickness of pipes or thickness fluctuation of plates. Secondly, melt containing incompletely molten particles will produce surface defects when passing through the mold, such as the common "sharkskin" phenomenon or melt rupture. More seriously, local overheating may cause material decomposition, forming coke particles or bubbles in the product. These quality defects will affect the appearance of the product at best, and damage its performance at worst, such as reducing mechanical strength or affecting sealing performance.

[0037] Furthermore, the continued existence of these problems will accelerate equipment wear. The screw and barrel will wear out significantly faster when operating under abnormal conditions; the drive system will age due to fatigue caused by load fluctuations; and the heating elements will have a shortened lifespan due to unstable operating conditions. All of these will increase the maintenance costs of the equipment and shorten its overall service life.

[0038] From a production management perspective, these problems have far-reaching consequences. Unstable production processes make it difficult to execute production plans and force delivery cycles to be extended; frequent downtime for maintenance not only reduces equipment utilization but also increases labor costs; and quality fluctuations may lead to customer complaints or even returns. All of these factors will ultimately be reflected in rising production costs and declining market competitiveness.

[0039] In conclusion, the clogging and uneven heating problems in traditional plastic extrusion equipment are not isolated issues, but rather interconnected systemic problems. These problems, through complex interactions, affect the production and operation of enterprises from multiple dimensions, including equipment performance, product quality, and production costs. To fundamentally solve these problems, it is necessary to innovate the equipment design concept and establish a more intelligent and collaborative system solution.

[0040] Please see Figures 1-7 This invention provides an embodiment of a plastic extrusion device for processing plastic parts, comprising a base 1; and further comprising a mounting frame 2, a protective shell 3, and a temperature-conducting inner shell 4. Several mounting frames 2 are fixedly connected to the base 1, and the protective shell 3 is fixedly connected to the mounting frame 2. The temperature-conducting inner shell 4 is fixedly connected inside the protective shell 3. An extrusion assembly is provided on one side of the temperature-conducting inner shell 4, and the extrusion assembly is fixedly connected to the base 1. A first coupling 6 is fixedly connected to the output end of the extrusion assembly, and the extrusion assembly drives the first coupling 6 to rotate. A screw rod 7 is fixedly connected to the other end of the first coupling 6, and the screw rod 7 is rotatably connected to the temperature-conducting inner shell 4. Two hoppers 14 are fixedly connected to the temperature-conducting inner shell 4. An anti-clogging component is provided on one side of the hoppers 14, and a second bevel gear 10 is connected to the output end of the anti-clogging component. The anti-clogging component is used to drive... The second bevel gear 10 rotates, and a second coupling 11 is fixedly connected to the center of the second bevel gear 10. A stirring scraper 12 is fixedly connected to the other end of the second coupling 11. The second coupling 11 and the stirring scraper 12 are rotatably connected to the feeding hopper 14. According to production needs, different production raw materials are put into the two feeding hoppers 14. Then, the anti-clogging component outputs power to the second bevel gear 10, causing the second bevel gear 10 to drive the second coupling 11 to rotate. The second coupling 11 drives the stirring scraper 12 to rotate in the feeding hopper 14, conveying the raw materials in the feeding hopper 14 to the temperature-conducting inner shell 4. By causing the extrusion component to output power to the first coupling 6, the first coupling 6 drives the screw rod 7 to rotate in the temperature-conducting inner shell 4, so that the raw materials in the temperature-conducting inner shell 4 are uniformly heated, melted and extruded.

[0041] Please see Figures 2-5In this embodiment, the extrusion assembly includes a first motor 501 fixedly connected to the base 1. A first rotating shaft 502 is fixedly connected to the output end of the first motor 501. The first motor 501 drives the first rotating shaft 502 to rotate. A first spur gear 503 is fixedly connected to the other end of the first rotating shaft 502. A second spur gear 504 is meshed with the other side of the first spur gear 503. The second spur gear 504 is fixedly connected to a first coupling 6. A connecting housing 505 is provided on the outer side of the first spur gear 503 and the second spur gear 504. The connecting housing 505 is rotatably connected to the first rotating shaft 502 and the first coupling 6. Power is output from the first motor 501 to the first rotating shaft 502, causing the first rotating shaft 502 to rotate. 502 drives the first spur gear 503 to rotate, causing the second spur gear 504 meshing on one side to rotate in conjunction with the first spur gear 503. This enables the second spur gear 504 to drive the first coupling 6 to rotate. The connecting housing 505 limits the movement of the first spur gear 503 and the second spur gear 504, ensuring a stable structural connection. The anti-blocking component includes a drive component fixedly connected to the base 1. The output end of the drive component is connected to two transmission components. The drive component drives the two transmission components to rotate, and the transmission components drive the second bevel gear 10 to rotate. Power is output from the drive component to the transmission components at both ends, and then the power is transmitted through the transmission components, enabling the same drive component to control two second bevel gears. The rotation of the 10th drive component includes a second motor 801 fixedly connected to the base 1. The output end of the second motor 801 is fixedly connected to a second rotating shaft 802. The second motor 801 drives the second rotating shaft 802 to rotate. The other end of the second rotating shaft 802 is fixedly connected to a drive turntable 803. A belt 804 is fitted around the outside of the drive turntable 803. The belt 804 is fitted on both sides of two transmission components. The second motor 801 outputs power to the second rotating shaft 802, causing it to rotate. This rotation drives the drive turntable 803 mounted on the second rotating shaft 802 to rotate. The power is then transmitted to the transmission components on both sides via the outer belt 804. The transmission components include a driven turntable 9 connected to the belt 804. 01. A transmission rod 902 is fixedly connected to the center of the driven turntable 901. A first bevel gear 903 is fixedly connected to the other end of the transmission rod 902. The transmission rod 902 is rotatably connected to the base 1. The first bevel gear 903 and the second bevel gear 10 are meshed together. An L-shaped limiting frame 13 is rotatably connected to one end of the transmission rod 902 near the first bevel gear 903. The other end of the L-shaped limiting frame 13 is rotatably connected to the second coupling 11. When the belt 804 rotates, it generates friction with the driven turntable 901, causing the driven turntable 901 to rotate. The driven turntable 901 drives the central transmission rod 902 to rotate, which in turn drives the first bevel gear 903 to rotate, thus causing the second bevel gear 10, which is meshed on one side, to rotate.The L-shaped limiting bracket 13 is used to limit the movement of the first bevel gear 903 and the second bevel gear 10, ensuring the stability of the connection structure.

[0042] Please see Figures 2-7In this embodiment, two air supply components are fixedly connected to the base 1. A heating component is fixedly connected to the output end of the air supply component. The air supply component is used to supply airflow to the heating component. The heating component is connected to the protective shell 3. The heating component is used to heat the supplied airflow. The air supply component generates airflow, which is blown towards the heating component. The heating component heats the airflow and then supplies the heated airflow between the protective shell 3 and the heat-conducting inner shell 4 to heat the device. The air supply component includes an air supply housing 1501 fixedly connected to the base 1. A third motor 1502 is fixedly connected inside the air supply housing 1501. A fan blade 1503 is fixedly connected to the output end of the third motor 1502. The third motor 1502 is used to drive the fan blade 1503 to move forward. The air supply housing 1501 rotates, and a finned filter 1504 is fixedly connected to the front end of the air supply housing 1501. Power is output from the third motor 1502 to the fan blades 1503, causing them to rotate and generate negative pressure. This draws outside air into the air supply housing 1501 after it passes through the finned filter 1504. The heating assembly includes a heating housing 1601 fixedly connected to the base 1. One end of the heating housing 1601 is connected to the air supply housing 1501, and the other end is connected to the protective housing 3. Two heating batteries 1602 are fixedly connected to both sides of the heating housing 1601, and several heating wires 1603 are fixedly connected between the two heating batteries 1602. Clean airflow from the air supply housing 1501 is blown into the heating housing 1601. The heating battery 1602 outputs current to multiple heating wires 1603, which convert electrical energy into heat energy to heat the airflow. After heating, the airflow is transported through the heating shell 1601 to the protective shell 3 and the temperature-conducting inner shell 4. A pressure sensor 17 and an extruder head 18 are fixedly connected to the end of the temperature-conducting inner shell 4 away from the first coupling 6. The pressure sensor 17 is electrically connected to the first motor 501. A sealing clamp 20 is movably connected to the other end of the extruder head 18. A clamping assembly is connected to one side of the sealing clamp 20 and is fixedly connected to the base 1. A mesh filter 19 is fixedly connected inside the extruder head 18. The pressure sensor 17 measures the pressure on the molten plastic inside the temperature-conducting inner shell 4 in real time and transmits the control signal. A signal is sent to the first motor 501 to control the speed of the screw rod 7, ensuring stable pressure during production. The mold is installed on the extruder head 18. Power is output through the clamping assembly to pull the sealing clamp 20, tightly connecting the mold and the extruder head 18. This allows the molten plastic in the temperature-conducting inner shell 4 to be conveyed into the mold for forming after passing through the mesh filter 19. The pressure sensor 17 in this device is a dedicated sensor for extrusion equipment, model PT123. The clamping assembly includes a hydraulic cylinder 2101 fixedly connected to the base 1. A hydraulic rod 2102 is fixedly connected to the output end of the hydraulic cylinder 2101. The hydraulic cylinder 2101 is used to push the hydraulic rod 2102 to perform linear motion. The other end of the hydraulic rod 2102 is fixedly connected to the upper opening of the sealing clamp 20.The hydraulic rod 2102 and the lower opening of the sealing clamp 20 are slidably connected. The hydraulic cylinder 2101 outputs pressure to the hydraulic rod 2102, causing it to move linearly. The hydraulic rod 2102 then moves the upper opening of the sealing clamp 20 towards its lower opening, thus clamping the mold.

[0043] During operation, different raw materials are fed into the two hoppers 14 according to production needs. Then, the second motor 801 outputs power to the second rotating shaft 802, causing the second rotating shaft 802 to rotate. This drives the active rotating disk 803 mounted on the second rotating shaft 802 to rotate. The active rotating disk 803 drives the belt 804 to rotate. The belt 804 generates friction with the driven rotating disk 901, causing the driven rotating disk 901 to rotate. The driven rotating disk 901 drives the central transmission rod 902 to rotate, which in turn drives the first bevel gear 903 to rotate. This causes the second bevel gear 10, which is meshed on one side, to rotate. The L-shaped limit bracket 13 then controls the rotation of the first bevel gear 903. 3. The second bevel gear 10 is limited in its movement, causing the second bevel gear 10 to drive the second coupling 11 to rotate. The second coupling 11 drives the stirring scraper 12 to rotate in the hopper 14, conveying the raw materials in the hopper 14 to the heat-conducting inner shell 4. Then, the first motor 501 outputs power to the first rotating shaft 502, causing the first rotating shaft 502 to rotate. The first rotating shaft 502 drives the first spur gear 503 to rotate, causing the second spur gear 504 meshing on one side to rotate with the first spur gear 503. This allows the second spur gear 504 to drive the first coupling 6 to rotate, and the connecting shell 505 limits the movement of the first spur gear 503 and the second spur gear 504. The coupling 6 drives the screw rod 7 to rotate within the temperature-conducting inner shell 4, generating significant shearing force and pressure on the raw materials within the shell. Simultaneously, the third motor 1502 outputs power to the fan blades 1503, causing them to rotate and creating negative pressure. This forces outside air through the finned filter 1504 into the air supply shell 1501. The clean airflow from the air supply shell 1501 is then blown into the heating shell 1601. The heating battery 1602 outputs current to multiple heating wires 1603, which convert electrical energy into heat energy. This heats the airflow, which is then transported through the heating shell 1601 to the space between the protective outer shell 3 and the temperature-conducting inner shell 4. 4. Heat transfer is performed to heat and melt the internal material. Then, the mold is installed on the extruder head 18. The hydraulic cylinder 2101 outputs pressure to the hydraulic rod 2102, which drives the hydraulic rod 2102 to move linearly. The hydraulic rod 2102 drives the upper opening of the sealing clamp 20 to move towards the lower opening of the sealing clamp 20, so that the sealing clamp 20 clamps the mold. The plastic melt in the heat-conducting inner shell 4 is transported into the mold for forming after passing through the mesh filter 19. During this process, the pressure sensor 17 measures the pressure on the plastic melt inside the heat-conducting inner shell 4 in real time and transmits the control signal to the first motor 501 to control the speed of the screw rod 7 to ensure stable pressure during the production process.

[0044] Through the above steps, the anti-clogging component drives the stirring scraper 12 to rotate, which not only breaks up clumps of raw materials but also continuously scrapes the bucket wall to prevent material adhesion and accumulation. This effectively prevents raw material bridging or clumping, allowing plastic granules to fall evenly. This avoids material supply interruptions caused by material blockage in traditional equipment, improves the automation level of the production line, reduces screw idling or overload caused by blockage, reduces mechanical wear, and extends the service life of key components. Furthermore, an air supply component is installed to work in conjunction with the heating component, ensuring that hot air evenly surrounds the temperature-conducting inner shell 4, forming a dynamic temperature-controlled environment. This ensures uniform heat distribution, preventing unmelted particles or thermal degradation of the plastic melt due to uneven heating. The stable temperature field makes the plastic melt flow more consistently, resulting in smoother extruded product surfaces and reducing defects such as bubbles and flow marks. It also efficiently utilizes heat energy, reduces ineffective heat dissipation, and lowers overall energy consumption. This solves the problems of easy blockage, disrupted production rhythm, reduced production quality, and increased energy consumption in traditional plastic extrusion equipment for plastic parts processing.
