DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] like Figures 1 to 14 As shown, a water ring hot cutting granulation unit according to an embodiment of the present invention includes a control unit 1, a feeding component 10, a mixing component 11, and an extrusion component 12; the control unit 1 controls the start and stop of the internal motors of the feeding component 10, the mixing component 11, and the extrusion component 12 through electrical signals, and the extrusion component 12 includes an extrusion head 2 fixed to the output end, and a water spray component is installed on the outside of the extrusion head 2;

[0039] A rotating shaft 21 is inserted through the center of the extruder head 2. A pair of connecting frames 3 are fixedly connected to the surface of the rotating shaft 21. A motor 31 is fixedly connected to the end of the connecting frame 3 away from the rotating shaft 21. A receiving wheel 32 is fixedly connected to the output end of the motor 31. A plurality of feed assemblies are installed on the annular surface of the receiving wheel 32; a hot cutter 35 is fixedly connected to the end of the feed assembly away from the receiving wheel 32; a material receiving member 14 is installed below the extruder head 2;

[0040] It should be noted that the feeding assembly 10 is used to receive raw materials from the outside. The feeding assembly 10 includes a hopper and a storage bin; the hopper is used to receive materials from the outside, and the materials may be divided into different types. The storage bin is used to temporarily store the materials; a first motor is installed in the storage bin, and a conveying auger is arranged at the output end of the motor. The feeding assembly 10 conveys the raw materials to the mixing assembly 11 through a conduit. The conveying auger is installed in the pipeline between the feeding assembly 10 and the mixing assembly 11. When conveying materials, the first motor installed in the storage bin starts, and the first motor drives the conveying auger to rotate, conveying the materials in the storage bin to the mixing assembly 11. The mixing assembly 11 mixes different materials together. The mixing assembly 11 includes a mixing tank, and a stirring rod is arranged inside the mixing tank. The stirring rod is driven by a second motor inside. When mixing, the second motor drives the stirring rod to rotate. A third motor is also arranged inside the mixing tank, and a feeding auger is installed at the output end of the third motor. The feeding auger is arranged in the pipeline between the mixing assembly 11 and the extrusion assembly 12. When the mixing assembly 11 conveys materials to the extrusion assembly 12, the third motor drives the feeding auger to rotate. When the feeding auger rotates, it conveys the materials inside the mixing tank to the extrusion assembly 12. The extrusion assembly 12 includes an extrusion chamber, the extrusion chamber is connected to the mixing tank through a pipeline, and the extrusion head 2 is communicated with the extrusion chamber through a pipeline. A fourth motor is arranged inside the extrusion chamber, and a conveying auger is installed at the output end of the fourth motor. The conveying auger is located in the pipeline communicating between the extrusion head 2 and the extrusion chamber. When granulation operation is carried out, the fourth motor drives the conveying auger to rotate, and the feeding auger conveys the materials inside the extrusion chamber to the extrusion head 2. The extrusion head 2 extrudes the materials through the extrusion surface, and then cooperates with the hot cutting knife 35 to cut the particles; in addition, the control machine 1 controls the opening and closing of the motors inside the feeding assembly 10, the mixing assembly 11, and the extrusion assembly 12 through electrical signals.

[0041] In the actual granulation process, the tool needs to rotate relative to the extrusion die head due to friction. During the friction, friction is continuously generated between the blade of the tool and the extrusion die head, and the tool becomes worn. The worn tool is difficult to fully contact with the extrusion die head. Since the initial position of the tool is fixed and there is extrusion pressure between the tool and the extrusion die head, the extrusion pressure between the worn tool and the extrusion die head gradually decreases until it loses the extrusion pressure, thereby affecting the pelletizing effect. Therefore, the staff needs to replace the tool regularly, and replacing the tool will take up the time of the granulation operation; thus affecting the efficiency of granulation; and the service life of the tool needs to be further optimized. In order to solve the above problems, the embodiment of the present invention provides multiple structures such as a feed assembly and a hot cutter 35, so that the service life of the tool is extended. The specific use process is as follows: when in use, the blade of the hot cutter 35 is attached to the extrusion surface of the extrusion head 2; the extrusion surface of the extrusion head 2 is provided with an extrusion hole, and the extrusion assembly 12 extrude the internal plastic through the extrusion head 2, and the end of the rotating shaft 21 is connected to the driving source. During granulation, the driving source drives the rotating shaft 21 to rotate, and the rotating shaft 21 The hot cutter 35 is driven by the feed assembly to rotate in a circular manner on the extrusion surface of the extruder head 2; the plastic extruded from the extrusion surface is cut into granules; at the same time, water is sprayed through the water spray assembly; the granules and liquid water enter the material receiving member 14 below synchronously; when the hot cutter 35 rotates, the hot cutter 35 will continuously rub against the extrusion surface of the extruder head 2, and the blade of the hot cutter 35 will wear due to friction. When the hot cutter 35 rotates, the feed assembly will intermittently squeeze the hot cutter 35, and when the wear of the blade of the hot cutter 35 reaches the point where adjustment is required, When the hot cutter 35 reaches a certain level, that is, the hot cutter 35 needs to be replaced. At this time, the feed component synchronously squeezes the hot cutter 35, so that the hot cutter 35 moves further toward the position of the extruder head 2. The feed component can intermittently provide extrusion pressure to the hot cutter 35; the extrusion pressure will not change due to the change of the position of the hot cutter 35, so the hot cutter 35 will squeeze the extrusion surface of the extruder head 2 with a stable extrusion pressure, so the pelletizing of the hot cutter 35 remains stable, ensuring the pelletizing effect; at the same time, the hot cutter 35 that has been worn can be used continuously, extending its service life.

[0042] The feeding assembly includes a cylinder 33, which is fixed to the annular circumference of the receiving wheel 32; an air plate 331 is slidably connected to the interior of the cylinder 33, and a guide rod 34 is fixed to the side of the air plate 331. The end of the guide rod 34 located outside the cylinder 33 is fixed to the side of the hot cutter 35;

[0043] The end of the receiving wheel 32 away from the motor 31 is fixedly connected to the inflatable box 4. The side of the inflatable box 4 is connected and fixed with multiple solenoid valves 42. The output end of the solenoid valve 42 is connected and fixed with a conduit 43. The end of the conduit 43 away from the solenoid valve 42 is connected to the adjacent cylinder 33. An air pump 41 is installed on the side of the inflatable box 4, and the output end of the air pump 41 is connected to the inflatable box 4. A pressure relief valve 335 is installed on the side of the cylinder 33.

[0044] When the hot cutting knife 35 is worn and reaches the degree that adjustment is needed, the extrusion force of the hot cutting knife 35 on the inside of the cylinder 33 is reduced through the guide rod 34 and the air plate 331, and the gas pressure inside the cylinder 33 is reduced. The wear of the hot cutting knife 35 affects the pelletizing effect. There is a gas pressure sensor inside the cylinder 33. The gas pressure sensor detects the gas change inside the cylinder 33 and controls the air pump 41 to start. The air pump 41 fills the inside of the cylinder 33 with air. The air pump 41 pumps the outside air into the inside of the charging box 4. The charging box 4 fills the air into the conduit 43 through the solenoid valve 42. Then the conduit 43 fills the air into the inside of the cylinder 33. The pressure inside the cylinder 33 increases. When the gas pressure inside the cylinder 33 increases to a certain extent, that is, when the extrusion force required by the hot cutting knife 35 on the extrusion head 2 is reached, the pressure relief valve 335 discharges the excess gas inside the cylinder 33, and the gas pressure inside the cylinder 33 returns to the initial value. At this time, the gas pressure sensor controls the air pump 41 to close; the gas inside the cylinder 33 is continuously extruded by the air plate 331. Therefore, the extrusion force received by the air plate 331 is equal to the gas pressure inside the cylinder 33. The extrusion force received by the air plate 331 will be transmitted to the guide rod 34. Based on the principle that the action force and the reaction force of the force are equal in magnitude, the extrusion force of the air plate 331 on the guide rod 34 is equal to the gas pressure inside the cylinder 33. Furthermore, it can be concluded that the extrusion force of the guide rod 34 driving the hot cutting knife 35 on the extrusion head 2 is equal to the gas pressure inside the cylinder 33. Since the gas pressure inside the cylinder 33 remains at the initial value, as the hot cutting knife 35 is worn, the hot cutting knife 35 will be further pushed to maintain the extrusion force on the extrusion head 2 and return to the initial value. The pushing direction points to the extrusion head 2 to ensure the use effect of the hot cutting knife 35. When the hot cutting knife 35 is worn again after feeding, the hot cutting knife 35 will be fed again, that is, the air pump 41 starts intermittently, so that the hot cutting knife 35 can be continuously used when it is worn, and the service life of the hot cutting knife 35 is extended; it should be noted that the solenoid valve 42 cooperating with the currently used hot cutting knife 35 remains open; the solenoid valve 42 at other positions remains closed.

[0045] A push rod 332 is inserted into the side of the air cylinder 33. One end of the push rod 332 located inside the air cylinder 33 is fixedly connected to the air plate 331. A fixing frame 333 is fixedly connected to the side of the air cylinder 33. A pressure sensor 334 on the same straight line as the push rod 332 is installed on the surface of the fixing frame 333. Initially, there is a gap between the pressure-receiving end of the pressure sensor 334 and the end of the push rod 332. The pressure sensor 334 is connected to the controller of the motor 31 through an electrical signal. When the hot cutting knife 35 wears to a certain extent, the hot cutting knife 35 can no longer be used and needs to be replaced. As the hot cutting knife 35 wears, the air plate 331 gradually slides inside the air cylinder 33. When the hot cutting knife 35 wears to the point where it needs to be replaced, the air plate 331 drives the push rod 332 to move out of the air cylinder 33, and the end of the push rod 332 squeezes the pressure-receiving end of the pressure sensor 334. When the pressure sensor 334 is squeezed, it sends an electrical signal to the controller of the motor 31, causing the motor 31 to rotate counterclockwise by ninety degrees, so that another hot cutting knife 35 replaces the original hot cutting knife 35 for granulation cutting, realizing the automatic replacement of the hot cutting knife 35, which is convenient to use. And only when all the hot cutting knives 35 are unusable will the staff replace them, saving manpower and improving the automation effect of the granulation unit.

[0046] The pressure sensor 334 is connected to the controller of the extrusion assembly 12 through an electrical signal. When the motor 31 drives the receiving wheel 32 to rotate, the extrusion assembly 12 is controlled to stop the extrusion operation to prevent the plastic extruded by the extrusion head 2 from being missed during the replacement of the hot cutting knife 35, which affects the granulation quality.

[0047] A first filter 5 is arranged at the input end of the air pump 41. A fixing component is installed between the first filter 5 and the inflation box 4. When the air pump 41 is in use, the plastic particles are filtered through the first filter 5 to prevent the plastic particles from being sucked into the air pump 41 and causing damage to the air pump 41. And a connecting shaft 53 is fixedly connected to the center of the end of the first filter 5 facing the air pump 41. A plurality of fan blades 531 are fixedly connected to the side of the connecting shaft 53 in a ring shape. The fixing component includes a fixing rod 52. One end of the fixing rod 52 is fixedly connected to the surface of the inflation box 4. The other end of the fixing rod 52 is provided with an annular slide rail 51. The annular slide rail 51 is fixedly connected to the surface of the first filter 5. The end of the fixing rod 52 is slidably connected to the inside of the annular slide rail 51. When the air pump 41 is working, the air flow will act on the fan blades 531 on the side of the connecting shaft 53 when passing through the first filter 5. After the fan blades 531 are acted on by the air flow, they drive the connecting shaft 53 to rotate. And an annular slide rail 51 is fixedly connected to the side of the first filter 5, and the annular slide rail 51 is supported by the fixing rod 52. Therefore, the connecting shaft 5 can drive the first filter 5 to rotate, and the liquid water acting on the surface of the first filter 5 is thrown out by centrifugal force, preventing the air pump 41 from sucking the liquid water into the air cylinder 33 and ensuring the stability of the use of the air cylinder 33.

[0048] A rubber block 521 is fixedly connected to the side surface of the fixed rod 52. When the connecting shaft 53 drives the fan blade 531 to rotate, the end of the fan blade 531 intermittently impacts the rubber block 521. When the fan blade 531 rotates, the end of the fan blade 531 intermittently impacts the rubber block 521, causing the fixed rod 52 to vibrate. The vibration of the fixed rod 52 is transmitted to the first filter 5 through the annular slide rail 51, causing the first filter 5 to vibrate, thereby preventing plastic particles from being embedded in the filter holes on the surface of the first filter 5 and blocking the first filter 5. When the first filter 5 vibrates, it will cause the plastic particles in the filter holes to fall off, which is beneficial to improving the use effect of the first filter 5. It should be noted that a small amount of liquid water entering the cylinder 33 will be discharged through the pressure relief valve 335 and will not affect the use.

[0049] A second filter 54 is sleeved on the surface of the connecting shaft 53. The second filter 54 can further intercept liquid water and further prevent liquid water from entering the cylinder 33.

[0050] A first isolation cylinder 6 is arranged between the first filter 5 and the inflation box 4 to prevent liquid water and plastic particles from entering the air pump 41 through the gap between the input end of the air pump 41 and the second filter 54; a second isolation cylinder 13 fixedly connected to the side surface of the extrusion assembly 12 is arranged outside the extrusion head 2 to prevent the plastic particles cut out from being knocked flying to the outside of the material receiving part 14 and being difficult to collect when the reserved hot cutting knife 35 rotates.

[0051] The water spraying assembly includes a cylinder 15. A plurality of triangular blocks 152 are fixedly connected to the annular inner wall of the cylinder 15 at equal intervals. An annular water spray head 151 is installed inside the cylinder 15. A water storage box 30 is fixedly connected to the side of the connecting frame 3. A water inlet 303 pointing to the annular water spray head 151 is opened at the end of the water storage box 30. A water pushing plate 301 is slidably connected inside the water storage box 30. One side of the water pushing plate 301 away from the center of the cylinder 15 is fixedly connected with a push rod 302. The end of the push rod 302 away from the water pushing plate 301 penetrates to the outside of the water storage box 30. The top end of the water storage box 30 is fixedly connected and communicated with a water outlet head 304. When the water spraying assembly works, the cylinder 15 is fixedly connected to the side of the extrusion bin, and the extrusion head 2 is sleeved inside. The annular water spray head 151 is externally connected to a water pump. The water pump fills the annular water spray head 151 with external liquid water. Then, the liquid water sprayed by the annular water spray head 151 moves along the inner wall of the cylinder 15. Thus, the particles cut by the hot cutting knife 35 flow along with the liquid water when splashing onto the inner wall of the cylinder 15. When the rotating shaft 21 drives the connecting frame 21 to rotate, the connecting frame 21 drives the water storage box 30 to rotate synchronously. The water inlet 303 of the water storage box 30 points to the annular water spray head 151 and adheres to the inner wall of the cylinder 15. Therefore, part of the liquid water flowing on the inner wall of the cylinder 15 enters the water storage box 30 through the water inlet 303. As the water storage box 30 rotates, there is a centrifugal force on the water storage box 30. The water pushing plate 301 inside the water storage box 30 adheres to the inner wall on the side away from the center of the cylinder 15 inside the water storage box 30 under the action of the centrifugal force. The water storage box 30 drives the push rod 302 to rotate synchronously. The end of the push rod 302 outside the water storage box 30 will be intermittently squeezed by the triangular block 152 on the inner wall of the cylinder 15. The specific squeezing process is that the end of the push rod 302 initially contacts the inclined surface of the triangular block 152. Then, as the push rod 302 rotates, the end of the push rod 302 is continuously squeezed by the inclined surface of the triangular block 152, so that the push rod 302 drives the water pushing plate 301 to move inside the water storage box 30 against the centrifugal force, and the moving direction points to the center position of the cylinder 15. At this time, the water storage box 30 is already filled with liquid water. As the water pushing plate 301 moves, the liquid water inside the water storage box 30 will be sprayed out through the water outlet head 304. The water outlet of the water outlet head 304 points to the contact position between the cutting edge of the hot cutting knife 35 and the extrusion head 2. When the push rod 302 passes over the triangular block 152, the water pushing plate 301 resets under the action of the centrifugal force. The water storage box 30 repeats the process of receiving water through the water inlet 303 and repeats the above process when encountering the next triangular block 152;It should be noted that during the movement of the water pushing plate 301, a small amount of liquid water will be ejected from the water receiving port 303 of the water storage box 30 first. Then, as the water pushing plate 301 passes over the water receiving port 303, the liquid water inside the water storage box 30 is squeezed and discharged only through the water outlet head 304. The liquid water ejected from the water outlet head 304 acts on the contact position between the cutting edge of the hot cutting knife 35 and the extrusion head 2. Thus, during the granulation process, the cut particles can be cooled in time, enabling the cut particles to quickly harden, preventing the cut particles from splashing and hitting the hot cutting knife 35 and deforming. Additionally, the liquid water ejected from the water outlet head 304 acting on the contact position between the cutting edge of the hot cutting knife 35 and the extrusion head 2 can also prevent the particles cut from the raw materials with high viscosity from adhering to the surface of the hot cutting knife 35, preventing particle adhesion and accumulation on the surface of the hot cutting knife 35, ensuring the stability of the hot cutting knife 35 during operation. Moreover, the water receiving port 303 of the water storage box 30 is located between the extrusion head 2 and the annular water spraying head 151. Therefore, the cut particles will not enter the interior of the water receiving port 303 along with the liquid water on the inner wall of the cylinder 15.

[0052] In summary, in the above embodiments of the present invention, by providing a feeding assembly on one side of the hot cutting knife 35, specifically, the feeding assembly includes a cylinder 33. When the hot cutting knife wears and needs to be adjusted, the cylinder 33 is inflated and restored to its initial size, and the hot cutting knife 35 is further pushed to maintain the extrusion force with the extrusion head 2 and restored to the initial size, ensuring the use effect of the hot cutting knife 35, enabling it to be continuously used when worn, and extending the service life of the hot cutting knife 35.
