[0001] The invention relates to the field of plastic particle processing devices, and in particular to a plastic particle processing device and a use method thereof. Background Art

[0002] With the rise of Industry 4.0 and smart manufacturing, plastic granule hot melt devices are gradually becoming intelligent and information-based. By introducing Internet of Things technology and big data analysis, remote monitoring, fault diagnosis and automatic optimization and adjustment of the processing process can be achieved, further improving production efficiency and product quality, environmental protection and sustainable development. With the improvement of global environmental awareness, plastic granule hot melt devices are facing the pressure and opportunities of green transformation. The research and development and production of more environmentally friendly and energy-saving hot melt devices, as well as the optimization of production processes, the reduction of energy consumption and the reduction of waste emissions have become important directions for the development of the industry.

[0003] In the prior art, various gases are generated during the hot melting process of plastic particles. If these gases cannot be discharged in time, bubbles will form in the plastic melt. When the melt containing bubbles is used to form plastic products, the bubbles will cause quality problems such as pores, uneven surface, and reduced strength in the product. Therefore, a plastic particle processing device and a method for using the same are proposed. Summary of the invention

[0004] The present invention aims to solve the technical problem that various gases are generated during the hot melting process of plastic particles in the prior art. If these gases cannot be discharged in time, bubbles will form in the plastic melt. When the melt containing bubbles is used to mold plastic products, the bubbles will cause the products to have quality problems such as pores, uneven surface, and reduced strength. A plastic particle processing device and a method for using the same are provided.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a plastic particle processing device, including a hot melt box, a feed pipe, a hot melt device, an exhaust device, an anti-blocking device, and a controller. The hot melt box is a rectangular parallelepiped and is arranged on the ground.

[0006] The feed pipe is arranged on the right side of the hot melt box, and one end of the feed pipe passes through the side of the hot melt box and is communicated with the inside of the hot melt box.

[0007] The hot melt device is arranged in the hot melt box and connected with the hot melt box.

[0008] The exhaust device is arranged on the side of the hot melt box, connected to the hot melt box and connected to the hot melt device.

[0009] The anti-clogging device is arranged on the side of the exhaust device, connected to the hot melt box, and connected to the exhaust device.

[0010] The controller is arranged on the side of the hot melt box, fixedly connected to the side surface of the hot melt box, and electrically connected to the hot melt device.

[0011] When it is necessary to perform hot-melt operation on plastic particles, the staff puts the plastic particles into the feed pipe, and the plastic particles slide into the hot-melt box. Then the staff turns on the hot-melt device through the controller to perform hot-melt operation on the plastic particles, thereby accelerating the overall melting speed. At the same time, the lower layer of the melt can be brought to the upper layer, so that the temperature and composition of the melt in the vertical direction are more uniform, avoiding the phenomenon of melt stratification during the hot-melt process. At the same time, the hot-melt device is started to drive the exhaust device to start, so as to perform exhaust operation, which can effectively discharge the gas generated during the hot-melting of plastic particles to the outside, thereby making the plastic melt denser, thereby improving the quality of plastic products. At the same time, the exhaust device is started to drive the anti-blocking device to start, thereby preventing the solid components from condensing and avoiding affecting the exhaust operation.

[0012] Furthermore, the hot melt device includes two support plates, two slide grooves, two screw rods, two sliders, a first motor, a fixed plate, a second motor, a rotating rod, a plurality of stirring rods, and a plurality of heating rods. The two support plates are respectively and vertically symmetrically arranged above the hot melt box and are respectively fixedly connected to the upper surface of the hot melt box.

[0013] The two slide grooves are respectively arranged vertically on the side surfaces of the two support plates, and the two slide grooves are respectively arranged opposite to each other.

[0014] The axes of the two screw rods are respectively arranged vertically, the two screw rods are respectively arranged in the two slide grooves, the two ends of the two screw rods are respectively rotatably connected with the two support plates, and the rotation axes thereof are respectively arranged vertically.

[0015] The two sliding blocks are respectively sleeved on the two screw rods, respectively threadedly connected with the two screw rods, respectively slidably connected with the two sliding grooves, and the sliding directions thereof are respectively arranged vertically.

[0016] The axis of the first motor shaft is arranged vertically and coincides with the axis of the screw on the right. The first motor is arranged above the right support plate. The first motor shaft passes downward through the right support plate and is fixedly connected to the upper end of the right screw. The first motor is fixedly connected to the upper surface of the right support plate and is electrically connected to the controller.

[0017] The fixing plate is transversely arranged between the two sliders and is fixedly connected to the side surfaces of the two sliders respectively.

[0018] The axis of the second motor shaft is vertically arranged, and the second motor shaft passes through the fixed plate downward and extends to below the fixed plate. The second motor is fixedly connected to the upper surface of the fixed plate and is electrically connected to the controller.

[0019] The axis of the rotating rod is arranged vertically and coincides with the axis of the rotating shaft of the second motor. The rotating rod is arranged in the hot melt box. The upper end of the rotating rod passes through the top of the hot melt box upward and is fixedly connected to the rotating shaft of the second motor.

[0020] A plurality of stirring rods are respectively arranged laterally on the sides of the rotating rod and are respectively fixedly connected to the side surfaces of the rotating rod.

[0021] A plurality of heating rods are respectively arranged vertically on the inner side of the hot melt box, respectively fixedly connected to the inner side surface of the hot melt box, and respectively electrically connected to the controller.

[0022] When hot-melt operation is required on plastic particles, the staff puts the plastic particles into the feed pipe, and the plastic particles slide into the hot-melt box. The staff then turns on several heating rods through the controller to perform hot-melt operation on the plastic particles.

[0023] Then the staff turns on the second motor through the controller. The rotation of the second motor drives the rotating rod to rotate, and the rotation of the rotating rod drives several stirring rods to rotate. The rotation of several stirring rods can make the plastic particles constantly turn over in the hot melt box, so that the plastic particles in different positions can exchange positions with each other, so that the heat can be more evenly transferred to each particle, thereby accelerating the overall melting speed.

[0024] When melt stratification occurs during the hot melt process, at this time, the staff turns on the first motor through the controller. The rotation of the first motor drives the right screw to rotate, and the rotation of the right screw drives the slider to move upward. The upward movement of the right slider drives the fixed plate to move upward. The upward movement of the fixed plate drives the second motor to move upward. The upward movement of the second motor drives the rotating rod upward. The upward movement of the rotating rod drives several stirring rods to move upward. The upward movement of several stirring rods can bring the lower layer of the melt to the upper layer, so that the temperature and composition of the melt in the vertical direction are more uniform, thereby avoiding the phenomenon of melt stratification during the hot melt process.

[0025] Furthermore, a solenoid valve is fixedly connected to the middle of the feed pipe.

[0026] By setting a solenoid valve, outside air is prevented from entering the hot melt box.

[0027] Furthermore, the exhaust device includes a collection box, a vent, an activated carbon filter plate, a moving groove, a moving plate, a telescopic spring, a first exhaust port, a second exhaust port, a third exhaust port, a scraper, a one-way bearing, a transmission plate, and a support rod. The side of the collecting box is open and faces the right side. The collecting box is arranged on the side of the hot melt box and away from the feeding pipe. The collecting box is fixedly connected to the side surface of the hot melt box.

[0028] The vent is arranged on the side of the collection box, one end of the vent is communicated with the outside, and the other end is communicated with the inside of the collection box.

[0029] The activated carbon filter plate is vertically arranged in the collection box and fixedly connected to the inner side of the collection box.

[0030] The movable groove is L-shaped, and is arranged on the side of the hot melt box and close to the collecting box. The top of the movable groove is connected with the inside of the hot melt box.

[0031] The movable plate is L-shaped, and is arranged in the movable groove. The upper end of the movable plate is arranged in the hot melt box. The movable plate is slidably connected with the movable groove, and its sliding direction is vertically arranged.

[0032] The telescopic spring is vertically arranged in the moving groove, the telescopic spring is arranged above the moving plate, the upper end of the telescopic spring is fixedly connected to the inner top surface of the moving groove, and the lower end is fixedly connected to the upper surface of the moving plate.

[0033] The first exhaust port is arranged at the side of the hot melt box, the first exhaust port is arranged at the right side of the movable plate, one end of the first exhaust port is connected with the inside of the hot melt box, and the other end is connected with the inside of the movable groove.

[0034] The second exhaust port is arranged on the side of the hot melt box, the second exhaust port is arranged on the left side of the movable plate, the second exhaust port is arranged opposite to the first exhaust port, one end of the second exhaust port is connected to the inside of the movable groove, and the other end is connected to the inside of the collection box.

[0035] The third exhaust port is arranged in the middle of the movable plate, and the third exhaust port is staggered with the first exhaust port and the second exhaust port respectively.

[0036] The scraper is a square ring plate, which is arranged inside the hot melt box and above a plurality of stirring rods. The scraper is slidably connected to the inner side of the hot melt box, and its sliding direction is arranged vertically.

[0037] The axis of the one-way bearing is arranged vertically and coincides with the axis of the rotating rod. The one-way bearing is arranged above a plurality of stirring rods. The one-way bearing is sleeved on the rotating rod and fixedly connected with the rotating rod.

[0038] The transmission plate is arranged transversely in the hot melt box, and the transmission plate is sleeved on the one-way bearing, fixedly connected with the one-way bearing, and fixedly connected with the inner side surface of the scraper.

[0039] The support rod is vertically arranged above the transmission plate and close to the moving plate. The lower end of the support rod is fixedly connected to the upper surface of the transmission plate, and the upper end is fixedly connected to the upper end of the moving plate.

[0040] When the rotating rod moves upward, the one-way bearing moves upward, and the one-way bearing moves upward, which in turn drives the transmission plate to move upward. The transmission plate moves upward, which in turn drives the scraper and the support rod to move upward.

[0041] When the transmission plate moves upward and drives the scraper upward, the scraper can scrape off the melt attached to the inner wall of the hot melt box. If the melt remains on the box wall for a long time, it may gradually accumulate and solidify, which will not only occupy the effective space of the hot melt box, but also may affect the subsequent hot melt process.

[0042] When the transmission plate moves upward and drives the support rod to move upward, the support rod moves upward and drives the movable plate to move upward, and the movable plate moves upward and drives the third exhaust port to move upward until the third exhaust port is flush with the first exhaust port and the second exhaust port. At this time, the third exhaust port is connected with the first exhaust port and the second exhaust port respectively. Since the air pressure in the hot melt box is greater than the external air pressure, the gas in the hot melt box passes through the first exhaust port, the third exhaust port, the second exhaust port, and the collecting box in turn, and the gas discharged from the hot melt box is purified under the action of the activated carbon filter, and finally returns to the outside through the vent, thereby completing the exhaust operation, which can effectively discharge the gas generated during the hot melting of plastic particles to the outside, thereby making the plastic melt denser, thereby improving the quality of plastic products. If these gases cannot be discharged in time, bubbles will be formed in the plastic melt. When the melt containing bubbles is used to form plastic products, the bubbles will cause quality problems such as pores, uneven surface, and reduced strength in the product.

[0043] Furthermore, support legs are fixedly connected to the lower surface of the hot melt box.

[0044] The hot melt box can be easily fixed by providing supporting feet.

[0045] Furthermore, the anti-blocking device includes a transmission chamber, a piston rod, a pressure plate, an air inlet pipe, an air outlet chamber, two diversion chambers, three filter screens, and two one-way valves. The transmission chamber is arranged at the side of the hot melt box, the transmission chamber is arranged below the moving groove, and the upper end of the transmission chamber is communicated with the inside of the moving groove.

[0046] The piston rod is vertically arranged in the transmission cavity, and the upper end of the piston rod is fixedly connected to the lower surface of the moving plate.

[0047] The pressure plate is arranged horizontally below the piston rod, is fixedly connected to the lower end of the piston rod, and is slidably connected to the inner wall of the transmission cavity, and its sliding direction is arranged vertically.

[0048] The air inlet pipe is arranged at the side of the hot melt box and close to the transmission cavity. One end of the air inlet pipe passes through the side of the hot melt box and is communicated with the inside of the transmission cavity.

[0049] The air outlet cavity is arranged at the side of the transmission cavity, and one end of the air outlet cavity is communicated with the interior of the transmission cavity.

[0050] The two flow-dividing chambers are respectively arranged above the transmission chamber, one end of the two flow-dividing chambers is respectively communicated with the other end of the air outlet chamber, and the other end is respectively communicated with the first exhaust port and the second exhaust port.

[0051] The three filter screens are respectively arranged in the air inlet pipe and the two diversion chambers, and are respectively fixedly connected to the air inlet pipe and the inner walls of the two diversion chambers.

[0052] The two one-way valves are respectively arranged at the middle of the air inlet pipe and the air outlet cavity, and are respectively fixedly connected to the air inlet pipe and the air outlet cavity.

[0053] When the movable plate moves upward, driving the piston rod upward, the piston rod moves upward, driving the pressure plate upward, and the pressure plate moves upward, allowing the outside air to enter the transmission cavity through the intake pipe and the filter, preparing for subsequent anti-blocking operations.

[0054] When the movable plate moves downward and drives the piston rod to move downward, the piston rod moves downward and drives the pressure plate to move downward. The downward movement of the pressure plate causes the gas in the transmission chamber to pass through the air outlet chamber and the two diversion chambers in sequence, and finally spray to the first exhaust port and the second exhaust port respectively, thereby effectively cleaning up the melt accumulated at the first exhaust port and the second exhaust port, preventing the solid components from condensing and blocking the first exhaust port and the second exhaust port, and avoiding affecting the exhaust operation.

[0055] Furthermore, a temperature indicator is fixedly connected to the outer surface of the hot melt box.

[0056] By setting a temperature indicator, it is convenient for workers to observe the temperature inside the hot melt box.

[0057] Furthermore, a sealing ring is fixedly connected at the connection between the rotating rod and the hot melt box.

[0058] A sealing ring is provided to prevent outside air from entering the hot melt box.

[0059] Furthermore, when melt stratification occurs during the hot melt process, the staff turns on the first motor through the controller. The rotation of the first motor drives the right screw to rotate, and the rotation of the right screw drives the slider to move upward. The upward movement of the right slider drives the fixed plate to move upward, and the upward movement of the fixed plate drives the second motor to move upward. The upward movement of the second motor drives the rotating rod upward, and the upward movement of the rotating rod drives several stirring rods to move upward. The upward movement of several stirring rods can bring the lower layer of the melt to the upper layer, making the temperature and composition of the melt in the vertical direction more uniform, thereby avoiding the phenomenon of melt stratification during the hot melt process.

[0060] Furthermore, when it is necessary to clean the inner wall of the hot melt box, the staff starts the first motor through the controller. The rotation of the first motor drives the screw on the right to rotate, and the rotation of the screw on the right drives the slider to move upward. The upward movement of the slider on the right drives the fixed plate to move upward, and the upward movement of the fixed plate drives the second motor to move upward. The upward movement of the second motor drives the rotating rod upward. The upward movement of the rotating rod drives the one-way bearing upward. The upward movement of the one-way bearing drives the transmission plate upward. The upward movement of the transmission plate drives the scraper upward. The upward movement of the scraper can scrape off the melt attached to the inner wall of the hot melt box. If the melt remains on the box wall for a long time, it may gradually accumulate and solidify, which will not only occupy the effective space of the hot melt box, but also affect the subsequent hot melt process.

[0061] Beneficial effects of the present invention: 1. The hot melt device and the exhaust device provided in the present invention interact and support each other, and can effectively discharge the gas generated when the plastic particles are hot-melted to the outside, thereby making the plastic melt denser, thereby improving the quality of the plastic products. If these gases cannot be discharged in time, bubbles will form in the plastic melt. When the melt containing bubbles is used to form plastic products, the bubbles will cause quality problems such as pores, uneven surface, and reduced strength in the product.

[0062] 2. The scraper, one-way bearing and transmission plate provided in the present invention interact and support each other, so that the melt attached to the inner wall of the hot melt box can be scraped off. If the melt remains on the inner wall of the hot melt box for a long time, it may gradually accumulate and solidify, which will not only occupy the effective space of the hot melt box, but also may affect the subsequent hot melt process.

[0102] When the transmission plate 409 moves upward and drives the scraper 408 to move upward, the scraper 408 moves upward to scrape off the melt attached to the inner wall of the hot melt box 1.

At this time, the third exhaust port 407 is connected with the first exhaust port 405 and the second exhaust port 406 respectively. Since the air pressure in the hot melt box 1 is greater than the external air pressure, the gas in the hot melt box 1 passes through the first exhaust port 405, the third exhaust port 407 in turn. , a second exhaust port 406, a collecting box 401, and the gas discharged from the hot melt box 1 is purified under the action of the activated carbon filter 507, and finally returned to the outside through the vent, thereby completing the exhaust operation. The gas generated when the plastic particles are hot-melted can be effectively discharged to the outside, thereby making the plastic melt denser, thereby improving the quality of the plastic products. If these gases cannot be discharged in time, bubbles will form in the plastic melt. When the melt containing bubbles is used to form plastic products, the bubbles will cause quality problems such as pores, uneven surface, and reduced strength in the product.

[0114] When the movable plate 403 moves upward and drives the piston rod 502 to move upward, the piston rod 502 moves upward and drives the pressure plate 503 to move upward. The pressure plate 503 moves upward and allows the outside air to enter the transmission chamber 501 through the air intake pipe 504 and the filter screen 507, preparing for the subsequent anti-blocking operation.

[0115] When the movable plate 403 moves downward and drives the piston rod 502 to move downward, the piston rod 502 moves downward and drives the pressure plate 503 to move downward. The pressure plate 503 moves downward so that the gas in the transmission chamber 501 passes through the gas outlet chamber 505 and the two diversion chambers 506 in sequence, and finally sprays to the first exhaust port 405 and the second exhaust port 406 respectively, thereby effectively cleaning up the melt accumulated at the first exhaust port 405 and the second exhaust port 406, preventing the solid components from condensing, and blocking the first exhaust port 405 and the second exhaust port 406 to avoid affecting the exhaust operation.

[0116] A temperature indicator is fixedly connected to the outer surface of the hot melt box 1.

[0117] By providing a temperature indicator, it is convenient for the staff to observe the temperature inside the hot melt box 1.

[0118] A sealing ring is fixedly connected at the connection between the rotating rod 307 and the hot melt box 1.

[0119] The sealing ring is provided to prevent external air from entering the hot melt box 1.

[0120] Working principle: When hot-melt operation is required on plastic particles, the staff puts the plastic particles into the feed pipe 2, and the plastic particles slide into the hot-melt box 1. Then the staff turns on several heating rods 309 through the controller 6 to perform hot-melt operation on the plastic particles.

[0121] Then the staff turns on the second motor 306 through the controller 6, and the rotation of the second motor 306 drives the rotating rod 307 to rotate, and the rotation of the rotating rod 307 in turn drives the plurality of stirring rods 308 and the inner ring of the one-way bearing to rotate.

[0122] When the rotating rod 307 rotates to drive the inner ring of the one-way bearing to rotate, the inner ring of the one-way bearing rotates to prevent the transmission plate 409 from rotating, thereby avoiding mechanical failure.

[0123] When the rotating rod 307 rotates to drive the plurality of stirring rods 308 to rotate, the rotation of the plurality of stirring rods 308 can cause the plastic particles to be constantly turned over in the hot melt box 1, so that the plastic particles at different positions exchange positions with each other, so that the heat can be more evenly transferred to each particle, thereby accelerating the overall melting speed.

[0124] When melt stratification occurs during the hot melting process, at this time, the staff turns on the first motor 304 through the controller 6, and the first motor 304 rotates to drive the right screw 302 to rotate, and the right screw 302 rotates to drive the slider 303 to move upward, and the right slider 303 moves upward to drive the fixed plate 305 to move upward, and the fixed plate 305 moves upward to drive the second motor 306 to move upward, and the second motor 306 moves upward to drive the rotating rod 307 to move upward, and the rotating rod 307 moves upward to drive the one-way bearing and several stirring rods 308 to move upward in turn.

[0125] When the rotating rod 307 moves upward and drives the plurality of stirring rods 308 to move upward, the plurality of stirring rods 308 can move upward to bring the lower layer of the melt to the upper layer, so that the temperature and composition of the melt in the vertical direction are more uniform, thereby avoiding the melt stratification phenomenon during the hot melting process.

[0126] When the rotating rod 307 moves upward, driving the one-way bearing to move upward, the one-way bearing moves upward, driving the transmission plate 409 to move upward, and the transmission plate 409 moves upward, driving the scraper 408 and the support rod 410 to move upward in turn.

[0127] When the transmission plate 409 moves upward and drives the scraper 408 to move upward, the scraper 408 moves upward to scrape off the melt attached to the inner wall of the hot melt box 1. If the melt remains on the box wall for a long time, it may gradually accumulate and solidify, which will not only occupy the effective space of the hot melt box 1, but also may affect the subsequent hot melt process.

[0128] When the transmission plate 409 moves upward, driving the support rod 410 to move upward, the support rod 410 moves upward, driving the movable plate 403 to move upward, and the movable plate 403 moves upward, driving the third exhaust port 407 and the piston rod 502 to move upward in sequence.

[0129] When the movable plate 403 moves upward and drives the third exhaust port to move upward, until the third exhaust port 407 is flush with the first exhaust port 405 and the second exhaust port 406, the third exhaust port 407 is connected with the first exhaust port 405 and the second exhaust port 406 respectively. Since the air pressure in the hot melt box 1 is greater than the external air pressure, the gas in the hot melt box 1 passes through the first exhaust port 405, the third exhaust port 407, the second exhaust port 406 and the collecting box 401 in turn, and the gas discharged from the hot melt box 1 is purified under the action of the activated carbon filter 507, and finally returns to the outside through the vent, thereby completing the exhaust operation, and can effectively discharge the gas generated during the hot melting of plastic particles to the outside, thereby making the plastic melt denser, thereby improving the quality of plastic products. If these gases cannot be discharged in time, bubbles will be formed in the plastic melt. When the melt containing bubbles is used to form plastic products, the bubbles will cause quality problems such as pores, uneven surface, and reduced strength in the product.

[0130] When the movable plate 403 moves upward and drives the piston rod 502 to move upward, the piston rod 502 moves upward and drives the pressure plate 503 to move upward. The pressure plate 503 moves upward and allows the outside air to enter the transmission chamber 501 through the air intake pipe 504 and the filter screen 507, preparing for the subsequent anti-blocking operation.

[0131] When the exhaust operation is completed, the staff turns on the first motor 304 through the controller 6. The first motor 304 rotates to drive the right screw 302 to rotate. The right screw 302 rotates to drive the slider 303 to move downward. The right slider 303 moves downward to drive the fixed plate 305 to move downward. The fixed plate 305 moves downward to drive the second motor 306 to move downward. The second motor 306 moves downward to drive the rotating rod 307 to move downward. The rotating rod 307 moves downward in turn to drive the one-way bearing and several stirring rods 308 to move downward.

[0132] When the rotating rod 307 moves downward and drives the plurality of stirring rods 308 to move downward, the plurality of stirring rods 308 can move the upper layer of the melt to the lower layer, so that the temperature and composition of the melt in the vertical direction are more uniform, thereby avoiding the melt stratification phenomenon during the hot melting process.

[0133] When the rotating rod 307 moves downward, driving the one-way bearing to move downward, the one-way bearing moves downward, driving the transmission plate 409 to move downward, and the transmission plate 409 moves downward, driving the scraper 408 and the support rod 410 to move downward in turn.

[0134] When the transmission plate 409 moves downward and drives the scraper 408 to move downward, the scraper 408 can scrape off the melt attached to the inner wall of the hot melt box 1. If the melt remains on the box wall for a long time, it may gradually accumulate and solidify, which will not only occupy the effective space of the hot melt box 1, but also may affect the subsequent hot melt process.

[0135] When the transmission plate 409 moves downward and drives the support rod 410 to move downward, the support rod 410 moves downward and drives the moving plate 403 to move downward, and the moving plate 403 moves downward and drives the third exhaust port 407 and the piston rod 502 to move downward in sequence.

[0136] When the movable plate 403 moves downward and drives the third row of ports to move downward, the third exhaust port 407 moves downward. At this time, the third exhaust port 407 is misaligned with the first exhaust port 405 and the second exhaust port 406, thereby stopping exhaust and preventing external air from flowing back, thereby maintaining the gas environment in the hot melt box 1 relatively stable and ensuring the quality of the melt.

[0137] When the movable plate 403 moves downward and drives the piston rod 502 to move downward, the piston rod 502 moves downward and drives the pressure plate 503 to move downward. The pressure plate 503 moves downward so that the gas in the transmission chamber 501 passes through the gas outlet chamber 505 and the two diversion chambers 506 in sequence, and finally sprays to the first exhaust port 405 and the second exhaust port 406 respectively, thereby effectively cleaning up the melt accumulated at the first exhaust port 405 and the second exhaust port 406, preventing the solid components from condensing, and blocking the first exhaust port 405 and the second exhaust port 406 to avoid affecting the exhaust operation.

[0138] The method of using the plastic particle processing device is as follows: when melt stratification occurs during the hot melting process, the staff turns on the first motor 304 through the controller 6, and the first motor 304 rotates to drive the right screw 302 to rotate, and the right screw 302 rotates to drive the slider 303 to move upward, and the right slider 303 moves upward to drive the fixed plate 305 to move upward, and the fixed plate 305 moves upward to drive the second motor 306 to move upward, and the second motor 306 moves upward to drive the rotating rod 307 to move upward, and the rotating rod 307 moves upward to drive a plurality of stirring rods 308 to move upward, and the plurality of stirring rods 308 move upward to bring the lower layer of the melt to the upper layer, so that the temperature and composition of the melt in the vertical direction are more uniform, thereby avoiding the phenomenon of melt stratification during the hot melting process.
