Description

Technical Field

[0001] This application relates to the field of extruder equipment technology, and in particular to an extruder temperature control device with adaptive dynamic stirring and cooling. Background Technology

[0002] Extruders are core equipment in the plastics processing industry. Their main function is to heat, melt, mix, and extrude plastic particles into shapes. In the extruder's working process, plastic particles first enter the feed hopper and then fall from the feed hopper into the extrusion screw for melting and plasticizing.

[0003] In related technologies, plastic particles that have undergone pre-drying or are freshly produced using a hot-cutting process often enter the feed hopper at a high temperature. Excessive temperature hinders the melting and plasticizing of these plastic particles; therefore, they require a certain degree of cooling before entering the screw extrusion molding process.

[0004] However, traditional extruder feed boxes mostly use natural cooling or simple jacketed water cooling on the outer wall of the box. Due to the high bulk density and poor thermal conductivity of plastic particles, external cooling can only cool the particles close to the box wall, while the particles in the center are in a "stuck" state, and the heat cannot be dissipated in time, resulting in uneven cooling and low cooling efficiency. Summary of the Invention

[0005] This application provides an extruder temperature control device with adaptive dynamic stirring and cooling, aiming to improve the cooling efficiency and uniformity of high-temperature plastic particles in the feed box, and prevent the plastic particles from sticking together or melting due to localized overheating within the feed box. Simultaneously, it breaks the static accumulation of plastic particles within the feed box, achieving dynamic tumbling and mixing of the particles, ensuring full contact with the cooling medium. This effectively ensures continuous and stable feeding of plastic particles, thereby achieving efficient cooling and uniform conveying of high-temperature plastic particles, ultimately improving the overall operational stability of the extruder and product quality.

[0006] This application provides an extruder temperature control device with adaptive dynamic stirring and cooling, which adopts the following technical solution: An adaptive dynamic stirring and cooling extruder temperature control device includes a frame, on which a DC motor, a gearbox, a feed box, an extrusion screw, a screw sleeve, and a discharge port are respectively mounted. The front and rear ends of the extrusion screw are connected to the feed box and the discharge port, respectively. A cooling plate and a stirring shaft are added to the feed box. Multiple stirring plates are integrally formed on the periphery of the stirring shaft, and the multiple stirring plates are evenly distributed on the periphery of the stirring shaft. The cooling plate is used to cool and reduce the temperature of the stirring plates.

[0007] By adopting the above technical solution, after the plastic particles enter the feed box, they are stirred by these agitator plates, which can effectively prevent the high-temperature plastic particles from accumulating statically in the feed box, thus ensuring smooth feeding of plastic particles and ensuring continuous and stable production of the extruder.

[0008] Simultaneously, when the agitator plates stir the high-temperature plastic particles, they come into direct contact with these particles. The cooled agitator plates then stir the particles, providing a more direct and effective cooling effect. This significantly improves the cooling efficiency. By simultaneously stirring and cooling the plastic particles, the agitator plates effectively break the static accumulation of the particles in the feed hopper, enabling dynamic tumbling and mixing. This ensures full contact between the particles and the cooling medium, guaranteeing a continuous and stable feed of plastic particles. Ultimately, this achieves efficient cooling and uniform conveying of the high-temperature plastic particles, improving the overall operational stability of the extruder and the quality of the products.

[0009] Preferably, the top of the feeding box is integrally connected to a feeding pipe, the cooling plate is horizontally sleeved around the periphery of the feeding pipe, the stirring plate is horizontally rotatably installed inside the feeding pipe, the side wall of the cooling plate has multiple ventilation grooves, the multiple ventilation grooves are evenly distributed along the periphery of the cooling plate, a ventilation plate is horizontally slidably installed inside the ventilation groove, the end of the stirring plate near the cooling plate has an air inlet, and a driving component is horizontally installed inside the stirring plate. The driving component is used to drive the ventilation plate to slide horizontally. During the sliding process, the cold air in the cooling plate flows through the ventilation groove to the air inlet at the end of the stirring plate, and enters the stirring plate through the air inlet.

[0010] By adopting the above technical solution, when the stirring plate is in a static state, the air permeable plate is located in the air permeable groove. In this state, the air permeable groove is sealed by the air permeable plate. The air permeable groove and the cooling plate are not connected. The rest of the cooling plate is sealed through the outer wall of the feed pipe. At this time, the cooling plate is in a sealed state, and the cold air in the cooling plate only flows inside the cooling plate. As plastic particles are added into the feed pipe, the agitator plate begins to rotate. During rotation, when the agitator plate reaches the position of the vent plate, the drive component inside the agitator plate abuts against the vent plate and compresses it. Under the compression of the drive component, the vent plate slides away from the vent groove until the vent groove opens and connects with the cooling plate. After the vent groove and cooling plate are connected, the air inlet at the end of the agitator plate is in the position of the vent groove. At this time, the cold air in the cooling plate flows through the vent groove to the air inlet and enters the agitator plate through the air inlet.

[0011] Preferably, a telescopic spring is installed horizontally between the inner walls of the vent plate and the cooling plate, with one end of the telescopic spring connected to the vent plate and the other end of the telescopic spring connected to the inner wall of the cooling plate.

[0012] By adopting the above technical solution, when the driving component squeezes the breathable plate, the extension spring drives the breathable plate to slide in the horizontal direction, and realizes the subsequent reset of the breathable plate.

[0013] Preferably, the end of the drive member near the vent plate is wedge-shaped.

[0014] By adopting the above technical solution, the end of the driving component is set as a wedge. When the driving component rotates to the position of the ventilated plate, it can effectively ensure that the driving component can continue to rotate smoothly from the position of the ventilated plate, effectively avoiding motion interference between the two, and thus effectively ensuring that the driving component can smoothly squeeze the ventilated plate during rotation.

[0015] Preferably, a first guide groove is provided in the ventilated groove along the sliding direction of the ventilated plate, and the ventilated plate is located in the first guide groove.

[0016] By adopting the above technical solution, the first guide groove guides the sliding of the breathable plate during the horizontal sliding process, which helps to ensure the stability of the breathable plate during the sliding process.

[0017] Preferably, the inner wall of the feed pipe is provided with a second guide groove along its circumference, and the end of the drive member near the vent plate is located in the second guide groove.

[0018] By adopting the above technical solution, the second guide groove guides the drive component during the rotation of the agitator plate, which helps to ensure the stability of the drive component during the rotation process.

[0019] Preferably, a temperature control box for adjusting the temperature of the plastic particles is provided between the feed box and the discharge port. Multiple temperature control boxes are provided, and the multiple temperature control boxes are evenly distributed at intervals along the length direction of the extrusion screw.

[0020] By adopting the above technical solution, the temperature of these temperature control chambers is set from low to high along the direction of plastic particle transport. By using these temperature control chambers to gradually increase the temperature of the plastic particles during the extrusion molding process in the extrusion screw, the quality of the plastic particles melt molding is effectively guaranteed.

[0021] Preferably, a fan is connected to the bottom of the temperature control chamber for cooling the plastic particles, and a heat sensor is installed on the top of the temperature control chamber for heating the plastic particles.

[0022] By adopting the above technical solution, and utilizing the fans and thermal sensors at both ends of the temperature control chamber, it is possible to effectively ensure that the plastic particles are always maintained within a reasonable temperature range during the extrusion molding process in the extrusion screw.

[0023] Preferably, a filter plate is installed at the discharge port of the extruder.

[0024] By adopting the above technical solution, during the extrusion molding process, incompletely melted particles, metal fragments, carbides, gel particles or other impurities may be mixed into the molten plastic. By using a filter plate to filter the impurities in the plastic particles, it is possible to effectively prevent these impurities from entering the mold, thereby helping to ensure product quality and stability during the processing.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. After the plastic particles enter the feed box, they are stirred by these agitator plates, which effectively prevents the high-temperature plastic particles from accumulating statically in the feed box, thus ensuring smooth feeding of plastic particles and ensuring continuous and stable production of the extruder.

[0026] Simultaneously, when the agitator plates stir the high-temperature plastic particles, they come into direct contact with these particles. The cooled agitator plates then stir the high-temperature plastic particles more directly and effectively, significantly improving the cooling effect. By simultaneously stirring and cooling the plastic particles, the static accumulation of the particles in the feed hopper is broken, allowing for dynamic tumbling and mixing. This ensures full contact between the particles and the cooling medium, guaranteeing continuous and stable feeding of the plastic particles. This results in efficient cooling and uniform conveying of the high-temperature plastic particles, thereby improving the overall operational stability of the extruder and product quality. 2. When the stirring plate is stationary, the vent plate is located in the vent groove. In this state, the vent groove is sealed by the vent plate. The vent groove and the cooling plate are not connected. The rest of the cooling plate is sealed by the outer wall of the feed pipe. At this time, the cooling plate is in a sealed state, and the cold air in the cooling plate only flows inside the cooling plate. As plastic particles are added into the feed pipe, the agitator plate begins to rotate. During rotation, when the agitator plate reaches the position of the vent plate, the drive component inside the agitator plate abuts against the vent plate and squeezes it. Under the squeezing action of the drive component, the vent plate slides away from the vent groove until the vent groove opens and connects with the cooling plate. After the vent groove and cooling plate are connected, the air inlet at the end of the agitator plate is in the position of the vent groove. At this time, the cold air in the cooling plate flows through the vent groove to the air inlet and enters the agitator plate through the air inlet. 3. By setting the end of the driving component to a wedge shape, when the driving component rotates to the position of the ventilated plate, it can effectively ensure that the driving component can continue to rotate smoothly from the position of the ventilated plate, effectively avoiding motion interference between the two, and thus effectively ensuring that the driving component can smoothly squeeze the ventilated plate during rotation.

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0030] Example: This application discloses an extruder temperature control device with adaptive dynamic stirring and cooling, referring to... Figure 1 and Figure 2The device includes a frame 1, on which are mounted a DC motor 2, a gearbox 3, a feed box 4, an extrusion screw 5, a screw sleeve 6, and a discharge port 7. The front and rear ends of the extrusion screw 5 are connected to the feed box 4 and the discharge port 7, respectively. The DC motor 2 and the gearbox 3 serve as the power source for the extrusion screw 5 to transport materials. The DC motor 2 and the gearbox 3 are connected by a synchronous belt. The DC motor 2 drives the gears in the gearbox 3 to rotate via the synchronous belt. The extrusion screw 5 is connected to the gears in the gearbox 3, and thus the gears in the gearbox 3 drive the extrusion screw 5 to rotate.

[0031] During the specific processing, plastic particles are injected into the feed box 4 and transported to the extrusion screw 5 through the feed box 4. As the extrusion screw 5 rotates, it gradually transports the plastic particles to the discharge port 7 for extrusion. During this process, the plastic particles are gradually extruded and formed.

[0032] Reference Figure 1 and Figure 2 Cooling plates 8 and stirring shafts 9 are added at four points in the feed box.

[0033] The cooling plate 8 is filled with cooling gas, which cools the temperature inside the feed box 4. This allows the plastic particles to effectively reduce their temperature after entering the feed box 4, facilitating subsequent melting and molding.

[0034] Reference Figure 1 and Figure 2 The stirring shaft 9 is vertically positioned and driven by an external motor. Multiple agitator plates 10 are integrally formed on the periphery of the stirring shaft 9, and these plates 10 are evenly distributed at intervals along its periphery. After the plastic particles enter the feed box 4, they are agitated by these agitator plates 10, effectively preventing the high-temperature plastic particles from stagnating and accumulating within the feed box 4. This ensures smooth feeding of the plastic particles and guarantees continuous and stable production from the extruder.

[0035] Meanwhile, as the stirring plate 10 rotates, the cold air inside the cooling plate 8 will enter the stirring plate 10, and the stirring plate 10 will be cooled by this cold air.

[0036] When agitating the high-temperature plastic particles, the agitator 10 comes into direct contact with them. The cooled agitator 10 then further cools the particles more directly and effectively, significantly improving the cooling effect. By simultaneously agitating and cooling the plastic particles, the agitator 10 breaks the static accumulation of the particles in the feed box 4, enabling dynamic tumbling and mixing. This ensures full contact between the particles and the cooling medium, guaranteeing continuous and stable feeding. This results in efficient cooling and uniform conveying of the high-temperature plastic particles, ultimately improving the overall operational stability of the extruder and the product quality.

[0037] Specifically, refer to Figure 1 and Figure 2 The cooling plate 8 has a ring-shaped structure, and the top of the feed box 4 is integrally connected to the feed pipe 11. The cooling plate 8 is horizontally sleeved around the periphery of the feed pipe 11. The stirring plate 10 is horizontally rotatably installed inside the feed pipe 11. The side wall of the cooling plate 8 has multiple ventilation grooves 12, which are evenly distributed along the periphery of the cooling plate 8. Ventilation plates 13 are horizontally slidably installed inside the ventilation grooves 12.

[0038] At the same time, refer to Figure 3 and Figure 4 The stirring plate 10 is hollow inside, and an air inlet 14 is provided at one end of the stirring plate 10 near the cooling plate 8. A driving component 15 is installed horizontally inside the stirring plate 10, which is used to drive the vent plate 13 to slide horizontally. During the sliding process of the vent plate 13, the cold air in the cooling plate 8 flows through the vent groove 12 to the air inlet 14 at the end of the stirring plate 10, and enters the stirring plate 10 through the air inlet 14, thereby achieving the cooling of the stirring plate 10.

[0039] When the stirring plate 10 is stationary, the vent plate 13 is located in the vent groove 12. In this state, the vent groove 12 is sealed by the vent plate 13. The vent groove 12 and the cooling plate 8 are not connected. The rest of the cooling plate 8 is sealed by the outer wall of the feed pipe 11. At this time, the cooling plate 8 is in a sealed state, and the cold air in the cooling plate 8 only flows in the cooling plate 8. As plastic particles are added into the feed pipe 11, the agitator 10 begins to rotate. During rotation, when the agitator 10 reaches the position of the vent plate 13, the drive component 15 inside the agitator 10 comes into contact with the vent plate 13 and compresses it. Under the compression of the drive component 15, the vent plate 13 slides away from the vent groove 12 until the vent groove 12 opens and connects with the cooling plate 8. After the vent groove 12 and the cooling plate 8 are connected, the air inlet 14 at the end of the agitator 10 is located at the position of the vent groove 12. At this time, the cold air in the cooling plate 8 flows through the vent groove 12 to the air inlet 14 and enters the agitator 10 through the air inlet 14.

[0040] Specifically, refer to Figure 3 and Figure 4 A telescopic spring 16 is installed horizontally between the inner walls of the vent plate 13 and the cooling plate 8. One end of the telescopic spring 16 is connected to the vent plate 13, and the other end is connected to the inner wall of the cooling plate 8. When the driving member 15 presses the vent plate 13, the telescopic spring 16 drives the vent plate 13 to slide horizontally, thereby achieving the subsequent reset of the vent plate 13.

[0041] Specifically, the end of the drive member 15 near the ventilated plate 13 is wedge-shaped. By setting the end of the drive member 15 to a wedge shape, when the drive member 15 rotates to the position of the ventilated plate 13, it can effectively ensure that the drive member 15 can continue to rotate smoothly from the position of the ventilated plate 13, effectively avoiding motion interference between the two, and thus effectively ensuring that the drive member 15 can smoothly squeeze the ventilated plate 13 during rotation.

[0042] Furthermore, referring to Figure 2 and Figure 3 A first guide groove 17 is provided in the ventilation groove 12 along the sliding direction of the ventilation plate 13, and the ventilation plate 13 is located in the first guide groove 17. During the horizontal sliding process of the ventilation plate 13, the first guide groove 17 guides the sliding of the ventilation plate 13, which helps to ensure the stability of the ventilation plate 13 during the sliding process.

[0043] Furthermore, referring to Figure 2 , Figure 3 as well as Figure 4 The inner wall of the feed pipe 11 is provided with a second guide groove 18 along its circumference, and the end of the drive member 15 near the vent plate 13 is located in the second guide groove 18. During the rotation of the drive member 15 driven by the agitator plate 10, the second guide groove 18 guides the drive member 15, which helps to ensure the stability of the drive member 15 during rotation.

[0044] Furthermore, referring to Figure 1A temperature control chamber 19 for regulating the temperature of plastic particles is provided between the feed box 4 and the discharge port 7. Multiple temperature control chambers 19 are provided and are evenly distributed along the length of the extrusion screw 5. The temperature of these temperature control chambers 19 is set from low to high along the direction of plastic particle transport. By using these temperature control chambers 19 to gradually increase the temperature of the plastic particles during the extrusion molding process in the extrusion screw 5, the quality of the melt molding of these plastic particles can be effectively guaranteed.

[0045] Specifically, refer to Figure 1 The bottom of the temperature control chamber 19 is connected to a fan 20, which is used to cool down the plastic particles, thereby effectively preventing the plastic particles from getting too hot during the extrusion molding process and affecting the quality of their melt molding.

[0046] At the same time, refer to Figure 1 A thermal sensor 21 is installed on the top of the temperature control chamber 19, and a heating shaft is installed inside the temperature control chamber 19 near its top. The thermal sensor 21 is used to control the heating shaft to heat up the plastic particles, thereby effectively preventing the plastic particles from being too cold during the extrusion molding process, which would affect the quality of their melt molding.

[0047] By utilizing the fans 20 at the top and bottom of the temperature control box 19 and the thermal sensors 21, it is possible to effectively ensure that the plastic particles are kept within a reasonable temperature range during the extrusion molding process in the extrusion screw 5.

[0048] Specifically, the temperature control chamber 19 is equipped with corresponding heaters distributed radially along the screw barrel, enabling uniform heating of the screw barrel. A thermal sensor 21 measures the temperature of the inner surface of the screw barrel. When the temperature exceeds the set temperature, the thermal sensor 21 controls the heaters to stop heating, and the bottom fan 20 starts operating to cool the corresponding area. When the temperature falls below the set value, the thermal sensor 21 controls the heaters to resume heating.

[0049] Reference Figure 1 A filter plate 22 is installed at the discharge port 7 of the extruder. During the extrusion molding process, the molten plastic may be mixed with incompletely melted particles, metal scraps, carbides, gel particles or other impurities. The filter plate 22 filters the impurities in the plastic particles, thereby effectively preventing these impurities from entering the mold, which helps to ensure product quality and stability during the processing.

[0050] The implementation principle of the adaptive dynamic stirring and cooling extruder temperature control device in this application embodiment is as follows: The device includes a frame 1, on which are mounted a DC motor 2, a gearbox 3, a feed box 4, an extrusion screw 5, a screw sleeve 6, and a discharge port 7. The front and rear ends of the extrusion screw 5 are connected to the feed box 4 and the discharge port 7, respectively. The DC motor 2 and the gearbox 3 serve as the power source for the extrusion screw 5 to transport materials. The DC motor 2 and the gearbox 3 are connected by a synchronous belt. The DC motor 2 drives the gears in the gearbox 3 to rotate via the synchronous belt. The extrusion screw 5 is connected to the gears in the gearbox 3, and thus the gears in the gearbox 3 drive the extrusion screw 5 to rotate.

[0051] During the specific processing, plastic particles are injected into the feed box 4 and transported to the extrusion screw 5 through the feed box 4. As the extrusion screw 5 rotates, it gradually transports the plastic particles to the discharge port 7 for extrusion. During this process, the plastic particles are gradually extruded and formed.

[0052] Cooling plates 8 and stirring shafts 9 are added at four points in the feed box.

[0053] The cooling plate 8 is filled with cooling gas, which cools the temperature inside the feed box 4. This allows the plastic particles to effectively reduce their temperature after entering the feed box 4, facilitating subsequent melting and molding.

[0054] The stirring shaft 9 is vertically positioned and driven by an external motor. Multiple agitator plates 10 are integrally formed on the periphery of the stirring shaft 9, and these plates 10 are evenly distributed at intervals along its periphery. After the plastic particles enter the feed box 4, they are agitated by these agitator plates 10, effectively preventing the high-temperature plastic particles from stagnating and accumulating within the feed box 4. This ensures smooth feeding of the plastic particles and guarantees continuous and stable production from the extruder.

[0055] Meanwhile, as the stirring plate 10 rotates, the cold air inside the cooling plate 8 will enter the stirring plate 10, and the stirring plate 10 will be cooled by this cold air.

[0056] When agitating the high-temperature plastic particles, the agitator 10 comes into direct contact with them. The cooled agitator 10 then further cools the particles more directly and effectively, significantly improving the cooling effect. By simultaneously agitating and cooling the plastic particles, the agitator 10 breaks the static accumulation of the particles in the feed box 4, enabling dynamic tumbling and mixing. This ensures full contact between the particles and the cooling medium, guaranteeing continuous and stable feeding. This results in efficient cooling and uniform conveying of the high-temperature plastic particles, ultimately improving the overall operational stability of the extruder and the product quality.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
