The control ends of the hot air blower, the second electric push rod, the second motor and the third motor are all electrically connected to an external power supply through an external switch, which is convenient for the operation of this device.
[0012] The operation method of this device: Step 1: Extrusion forming. The raw material is added into the interior of the extrusion box through the material cylinder, the raw material is heated and melted by the heating plate, heat insulation and heat preservation are carried out through the vacuum chamber, the temperature is monitored in real time by the temperature sensor, the first motor drives the spiral feeding rod to rotate, the material is pushed forward by the spiral feeding rod, so that pressure is generated at one end of the extrusion box, and the melted material is extruded through the nozzle under the action of the pressure to form a material rod; Step 2: Automatic adjustment. The pressure sensor controller can monitor the pressure at one end of the extrusion box in real time. When the pressure at one end of the extrusion box is too small, the first electric push rod drives the movable block, the first motor, and the push rod to move through the first push plate, so that the sealing push plate, the limiting block, and the spiral feeding rod move forward, ensuring the pressure at one end of the extrusion box, and further ensuring that the size of the extruded material rod is within an appropriate range. If the pressure is too large, the first electric push rod can pull the spiral feeding rod away from the nozzle at this time, thereby reducing the pressure; Step 3: Cooling. The material rod extruded by the nozzle is cooled by the cooling water in the cooling tank. The refrigeration plate at one end of the cooling tank can cool the cooling water. The cooling water in the cooling tank can be circulated internally through the water pump, the water outlet pipe, and the water inlet pipe. The extruded material rod is lifted by the support rod and isolated by the partition plate on the surface of the support rod to avoid mutual friction of the extruded material rods; Step 4: Traction. The cooled material rod enters the interior of the second channel through the first channel. The user can control the second push plate to move down through the second electric push rod. The spring can automatically control the pressure of the mounting plate and the movable roller on the material rod. The third motor can drive the movable roller to rotate. The movable roller can provide traction for the material rod to make the material rod move; Step 5: Drying. The hot air generated by the hot air blower enters the interior of the air flow bin through the air duct. The horn-shaped air flow bin can comprehensively dry the material rod to ensure that its surface is in a dry state; Step 6: Granulation. After the dried material rod moves out of the second channel, the material rod can be cut into uniformly sized particles by the high-speed rotating cutting knife.
[0013] The user adds raw materials into the interior of the extrusion box through a barrel, heats and melts the raw materials through a heating plate, conducts heat insulation and temperature preservation through a vacuum chamber to reduce temperature loss, conducts real-time temperature monitoring through a temperature sensor, drives a spiral feeding rod to rotate with a first motor, pushes the material forward through the spiral feeding rod, generates pressure at one end of the extrusion box, and under the action of the pressure, the melted material is extruded through a nozzle to form a material rod. At the same time, the pressure at one end of the extrusion box can be monitored in real time through a pressure sensing controller. When the pressure at one end of the extrusion box is too small, the material rod extruded through the nozzle will be too thin. To avoid the material rod being too thin, at this time, a first electric push rod pushes a movable block, a first motor and a push rod to move through a first push plate, so that a sealing push plate, a limiting block and a spiral feeding rod move forward, ensuring the pressure magnitude at one end of the extrusion box, and further ensuring that the size of the extruded material rod is within a suitable range. If the pressure is too high, at this time, the spiral feeding rod can be pulled away from the nozzle through the first electric push rod, thereby reducing the pressure magnitude. The material rod extruded by the nozzle is cooled by the cooling water inside a cooling tank, so that the material rod hardens. A refrigeration plate at one end of the cooling tank can cool the cooling water. Through a water pump, a water outlet pipe and a water inlet pipe, the cooling water inside the cooling tank can be circulated internally. The heated water after cooling is discharged to the surface of the refrigeration plate through the water pump and the water outlet pipe, thereby increasing and ensuring the cooling treatment of the cooling water. The cooled cooling water at the top of the refrigeration plate flows towards the nozzle, which can ensure that the temperature of the cooling water inside the cooling tank gradually decreases from the nozzle to the refrigeration plate, so that the extruded material rod can be gradually cooled, avoiding the rapid cooling of the material rod, which may cause the surface of the material rod to crack. The extruded material rod is lifted by a support rod and isolated by a partition plate on the surface of the support rod to avoid mutual friction of the extruded material rods. The cooled material rod enters the interior of a second channel through a first channel. The user can control a second push plate to move downward through a second electric push rod, and the pressure magnitude of an installation plate and a movable roller on the material rod can be automatically controlled through a spring, thereby avoiding breaking and damaging the material rod due to excessive pressure. At the same time, a third motor can drive the movable roller to rotate, and the movable roller can provide a traction force for the material rod to make the material rod move. The hot air generated by a hot air blower enters the interior of an air flow chamber through an air duct, and the material rod can be comprehensively dried through the horn-shaped air flow chamber to ensure that its surface is in a dry state. After the dried material rod moves out of the second channel, it can be cut into uniformly sized particles by a high-speed rotating cutting knife, thus completing the whole process of granulation. This device can perform granulation work fully automatically, and can also automatically adjust the magnitude of the extrusion pressure, thereby ensuring that the particle size is uniform, improving the granulation quality. At the same time, this device is fully automatic, which can reduce the workload and operation difficulty of the user. BRIEF DESCRIPTION OF THE DRAWINGS

The cutting edges of the cutting knife 45 are all arc-shaped, facilitating the cutting of the material rod. The control ends of the hot air blower 32, the second electric push rod 37, the second motor 44, and the third motor 46 are all electrically connected to the external power supply through an external switch, facilitating the operation of the device; The operation method of this device: Step 1: Extrusion forming. The raw material is added into the interior of the extrusion box 1 through the barrel 2. The raw material is heated and melted by the heating plate 5. Heat insulation and heat preservation are carried out through the vacuum chamber 6. The temperature is monitored in real time through the temperature sensor 19. The first motor 9 drives the spiral feed rod 7 to rotate. The material is pushed forward through the spiral feed rod 7, causing pressure at one end of the extrusion box 1. Under the action of the pressure, the melted material is extruded through the nozzle 3 to form a material rod; Step 2: Automatic adjustment. The pressure sensor controller 20 can monitor the pressure at one end of the extrusion box 1 in real time. When the pressure at one end of the extrusion box 1 is too small, the first electric push rod 14 pushes the movable block 8, the first motor 9, and the push rod 16 through the first push plate 13, so that the sealing push plate 15, the limiting block 18, and the spiral feeding rod 7 move forward, ensuring the pressure at one end of the extrusion box 1 and further ensuring that the size of the extruded material rod is within an appropriate range. If the pressure is too large, the first electric push rod 14 can pull the spiral feeding rod 7 away from the nozzle 3 at this time, thereby reducing the pressure; Step 3: Cooling. The material rod extruded from the nozzle 3 is cooled by the cooling water in the cooling tank 22. The refrigeration plate 25 at one end of the cooling tank 22 can cool the cooling water. The cooling water inside the cooling tank 22 can be circulated internally through the water pump 26, the water outlet pipe 27, and the water inlet pipe 28. The extruded material rod is lifted by the support rod 23 and isolated by the partition plate 24 on the surface of the support rod 23 to prevent the extruded material rods from rubbing against each other; Step 4: Traction. The cooled material rod enters the inside of the second channel 43 through the first channel 30. The user can control the second push plate 36 to move down through the second electric push rod 37. The spring 39 can automatically control the pressure of the mounting plate 38 and the movable roller 40 on the material rod. The third motor 46 can drive the movable roller 40 to rotate, and the movable roller 40 can provide traction for the material rod to make the material rod move; Step 5: Drying. The hot air generated by the hot air blower 32 enters the inside of the air flow bin 31 through the air duct 33. The horn-shaped air flow bin 31 can perform a comprehensive drying treatment on the material rod to ensure that its surface is in a dry state; Step 6: Pelletizing. After the dried material rod moves out of the second channel 43, the high-speed rotating cutting knife 45 can cut the material rod into uniformly sized particles.
[0018] Working principle: The user adds raw materials into the interior of the extrusion box 1 through the barrel 2, heats and melts the raw materials through the heating plate 5, conducts vacuum heat insulation through the vacuum chamber 6 to reduce temperature loss, and conducts real-time temperature monitoring through the temperature sensor 19. The first motor 9 drives the spiral feeding rod 7 to rotate, and the rotating spiral feeding rod 7 pushes the material forward, generating pressure at one end of the extrusion box 1. Under the action of the pressure, the melted material is extruded through the nozzle 3 to form a material rod. At the same time, the pressure sensing controller 20 can monitor the pressure at one end of the extrusion box 1 in real time. When the pressure at one end of the extrusion box 1 is too small, the material rod extruded through the nozzle 3 will be too thin. To avoid the material rod being too thin, at this time, the first electric push rod 14 pushes the first push plate 13 forward. The first push plate 13 drives the slider 12 to slide inside the chute 11, and the chute 11 and the slider 12 are used for guiding. The moving first push plate 13 pushes the movable block 8, the first motor 9, and the push rod 16 to move. The push rod 16 slides at one end of the extrusion box 1. The push rod 16 pushes the sealing push plate 15 to slide inside the sealing push plate 15, and the limiting block 18 slides inside the limiting groove 17. At this time, the sealing push plate 15, the limiting block 18, and the spiral feeding rod 7 move forward to ensure the pressure at one end of the extrusion box 1, and thus ensure that the size of the extruded material rod is within an appropriate range. If the pressure is too high, at this time, the first electric push rod 14 can pull the spiral feeding rod 7 away from the nozzle 3 to reduce the pressure. The material rod extruded by the nozzle 3 is cooled by the cooling water inside the cooling tank 22, so that the material rod becomes hard. The refrigeration plate 25 at one end of the cooling tank 22 can cool the cooling water. The cooling water inside the cooling tank 22 can be circulated internally through the water pump 26, the water outlet pipe 27, and the water inlet pipe 28. The heated water after cooling is discharged to the surface of the refrigeration plate 25 through the water pump 26 and the water outlet pipe 27, so as to ensure that the cooling water is cooled. The cooled cooling water at the top of the refrigeration plate 25 flows towards the nozzle 3, which can ensure that the temperature of the cooling water inside the cooling tank 22 gradually decreases from the nozzle 3 to the refrigeration plate 25, so as to gradually cool the extruded material rod and avoid the material rod cooling rapidly, resulting in cracks on the surface of the material rod. The extruded material rod is lifted by the support rod 23 and isolated by the partition plate 24 on the surface of the support rod 23 to avoid mutual friction between the extruded material rods. The cooled material rod enters the interior of the second channel 43 through the first channel 30. The user can control the second push plate 36 to move downward through the second electric push rod 37. The downward moving second push plate 36 makes the mounting plate 38 and the movable roller 40 move downward through the spring 39 until the movable roller 40 abuts against the material rod. At this time, the second electric push rod 37 continues to control the second push plate 36 to move downward. At this time, the second push plate 36 and the mounting plate 38 can compress the spring 39. At the same time, under the action of the self-returning force of the spring 39, the pressure of the movable roller 40 on the material rod can be increased, so as to clamp the material rod. The user controls the position of the second push plate 36 through the second electric push rod 37.Furthermore, it is possible to control the magnitude of the pressure exerted by the movable roller 40 on the material rod. At the same time, through the spring 39, it is also possible to automatically control the pressure exerted by the mounting plate 38 and the movable roller 40 on the material rod, thereby avoiding breaking and damaging the material rod due to excessive pressure. At the same time, the third motor 46 can drive the movable roller 40 to rotate, and through the movable roller 40, traction can be provided for the material rod, causing the material rod to move. The hot air generated by the hot air blower 32 enters the interior of the air flow chamber 31 through the air duct 33. Through the trumpet-shaped air flow chamber 31, the hot air can be evenly and comprehensively blown onto the surface of the material rod and finally discharged through the trumpet-shaped opening of the first channel 30, thereby enabling a comprehensive drying treatment of the material rod to ensure that its surface is in a dry state. After the dried material rod moves out of the second channel 43, through the high-speed rotating cutting knife 45, the material rod can be cut into uniformly sized particles, thus completing the entire granulation process. This device can perform granulation work fully automatically and can also automatically adjust the magnitude of the extrusion pressure, thereby ensuring uniform particle size and improving the granulation quality. At the same time, this device is fully automatic, which can reduce the workload and operation difficulty of users.,
