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 pointed out that the feeding component 10 is used to receive raw materials from the outside, and the feeding component 10 includes a hopper and a silo; the hopper is used to receive external materials, and the materials may be divided into different types, and the silo is used to temporarily store the materials; a first motor is installed in the silo, and a conveying auger is provided at the output end of the motor. The feeding component 10 conveys the raw materials to the mixing component 11 through a conduit, and the conveying auger is installed in the pipeline between the feeding component 10 and the mixing component 11. When conveying materials, the first motor installed in the silo is started, and the first motor drives the conveying auger to rotate, and conveys the materials in the silo to the mixing component 11. The mixing component 11 mixes different materials together. The mixing component 11 includes a mixing box, and a stirring rod is provided inside the mixing box. A second motor drive is provided inside the stirring rod. When mixing, the second motor drives the stirring rod to rotate. A third motor is also provided inside the mixing box, and a third motor is installed at the output end of the third motor. The feeding auger is arranged in a pipeline arranged between the mixing component 11 and the extrusion component 12. When the mixing component 11 feeds the material to the extrusion component 12, the third motor drives the feeding auger to rotate. When the feeding auger rotates, the material inside the mixing box is transported to the extrusion component 12. The extrusion component 12 includes an extrusion bin, which is connected to the mixing box through a pipeline. The extrusion head 2 is connected to the extrusion bin through a pipeline. A fourth motor is provided inside the extrusion bin. A feeding auger is installed at the output end of the fourth motor. The feeding auger is located in the pipeline connected between the extrusion head 2 and the extrusion bin. When the granulation operation is performed, the fourth motor drives the feeding auger to rotate, and the feeding auger transports the material inside the extrusion bin to the extrusion head 2. The extrusion head 2 extrude the material through the extrusion surface, and then cooperates with the hot cutting knife 35 to cut the pellets. In addition, the control machine 1 controls the opening and closing of the motors inside the feeding component 10, the mixing component 11, and the extrusion component 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 cutter 35 is worn and reaches the degree that needs to be adjusted, the hot cutter 35 reduces the squeezing force on the inside of the cylinder 33 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 cutter 35 affects the pelletizing effect, and the cylinder 33 is provided with an air pressure sensor. The air pressure sensor detects the gas change inside the cylinder 33 and controls the air pump 41 to start. The air pump 41 inflates the inside of the cylinder 33 and draws the outside air into the inside of the inflation box 4. The inflation box 4 is electrically The magnetic valve 42 fills air into the conduit 43, and then the conduit 43 fills air into the interior of the cylinder 33, and the pressure inside the cylinder 33 increases. When the air pressure inside the cylinder 33 increases to a certain extent, that is, when the hot cutter 35 exerts the required squeezing force on the extruder head 2, the pressure relief valve 335 releases the excess air inside the cylinder 33, and the air pressure inside the cylinder 33 is at the initial size. At this time, the air pressure sensor controls the air pump 41 to be turned off; the air inside the cylinder 33 is continuously squeezed by the air plate 331, so the air plate 331 is affected. The gas extrusion force received is equal to the gas pressure inside the cylinder 33. The extrusion force received by the gas plate 331 will be transmitted to the guide rod 34. Based on the principle that the action force and reaction force are equal in magnitude, the extrusion force of the gas plate 331 on the guide rod 34 is equal in magnitude to the gas pressure inside the cylinder 33. It can be concluded that the extrusion force of the hot cutter 35 driven by the guide rod 34 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 its initial value, as the hot cutter 35 wears, the hot cutter 35 35 will be further pushed to maintain the extrusion force with the extrusion head 2 to restore to its initial size, and the pushing direction is toward the extrusion head 2, to ensure the use effect of the hot cutter 35. When the hot cutter 35 is worn again after feeding, the hot cutter 35 will be fed again, that is, the air pump 41 is started intermittently, so that the hot cutter 35 can be used continuously when it is worn, thereby extending the service life of the hot cutter 35. It should be pointed out that the electromagnetic valve 42 of the hot cutter 35 currently in use remains open; the electromagnetic valve 42 in other positions remains closed.

[0045] The side of the cylinder 33 is connected with a push rod 332. One end of the push rod 332 located in the cylinder 33 is fixed to the gas plate 331. The side of the cylinder 33 is fixed with a fixing frame 333. The surface of the fixing frame 333 is installed with a pressure sensor 334 which is in the same line as the push rod 332. Initially, there is a gap between the pressure-bearing 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 cutter 35 is worn to a certain extent, the hot cutter 35 cannot be used any more and needs to be replaced. As the hot cutter 35 is worn, the gas plate 331 It gradually slides inside the cylinder 33. When the hot cutter 35 is worn and needs to be replaced, the air plate 331 drives the push rod 332 to move outside the cylinder 33, and the end of the push rod 332 squeezes the pressure end of the pressure sensor 334. When the pressure sensor 334 is squeezed, an electrical signal is sent to the controller of the motor 31, causing the motor 31 to rotate ninety degrees counterclockwise, so that another hot cutter 35 replaces the original hot cutter 35 for pelletizing, thereby realizing automatic replacement of the hot cutter 35 and facilitating use. Only when all the hot cutters 35 are unusable can they be replaced by staff, 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, and when the motor 31 drives the receiving wheel 32 to rotate, the extrusion assembly 12 is controlled to stop the extrusion operation to avoid the plastic extruded by the extrusion head 2 being missed when the hot cutter 35 is replaced, thereby affecting the granulation quality.

[0047] The input end of the air pump 41 is provided with a first filter 5, and a fixing assembly is installed between the first filter 5 and the inflatable 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 drawn into the air pump 41 and causing damage to the air pump 41. A connecting shaft 53 is fixedly connected to the center of one end of the first filter 5 facing the air pump 41, and a plurality of fan blades 531 are fixedly connected to the side of the connecting shaft 53 in an annular shape. The fixing assembly includes a fixing rod 52, one end of the fixing rod 52 is fixedly connected to the surface of the inflatable box 4, and the other end of the fixing rod 52 is provided with an annular slide rail 51, which is fixed to 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 airflow passes through the first filter 5 and acts on the fan blades 531 on the side of the connecting shaft 53. After being acted upon by the airflow, the fan blades 531 drive the connecting shaft 53 to rotate. The side of the first filter 5 is fixedly connected to the annular slide rail 51, and the annular slide rail 51 is supported by the fixing rod 52. Therefore, the connecting shaft 53 can drive the first filter 5 to rotate. The liquid water acting on the surface of the first filter 5 is thrown out by the centrifugal force, preventing the air pump 41 from drawing liquid water into the cylinder 33, thereby ensuring the stability of the cylinder 33 during use.

[0048] A rubber block 521 is fixed to the side of the fixing rod 52. When the connecting shaft 53 drives the fan blade 531 to rotate, the end of the fan blade 531 intermittently hits the rubber block 521. When the fan blade 531 rotates, the end of the fan blade 531 intermittently hits the rubber block 521, causing the fixing rod 52 to vibrate. The vibration of the fixing rod 52 is transmitted to the first filter disc 5 through the annular slide rail 51, causing the first filter disc 5 to vibrate, thereby preventing plastic particles from embedding into the filter holes on the surface of the first filter disc 5 and blocking the first filter disc 5. When the first filter disc 5 vibrates, the plastic particles in the filter holes will fall off, which is beneficial to improving the use effect of the first filter disc 5. It should be pointed out 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 disc 54 is sleeved on the surface of the connecting shaft 53 . The second filter disc 54 can further intercept liquid water and prevent the liquid water from entering the cylinder 33 .

[0050] A first isolation cylinder 6 is provided 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 of the extrusion component 12 is provided on the outside of the extrusion head 2 to prevent the cut plastic particles from being knocked to the outside of the material receiving piece 14 when the reserved hot cutter 35 rotates and is difficult to collect.

[0051] The water spray assembly includes a cylinder 15, a plurality of triangular blocks 152 are evenly fixed to the annular inner wall of the cylinder 15, and an annular water spray head 151 is installed inside the cylinder 15; a water storage box 30 is fixed to the side of the connecting frame 3, and a water inlet 303 pointing to the annular water spray head 151 is opened at the end of the water storage box 30, and a water pusher plate 301 is slidably connected to the inside of the water storage box 30, and a push rod 302 is fixed to the side of the water pusher plate 301 away from the center of the cylinder 15, and the end of the push rod 302 away from the water pusher plate 301 passes through the outside of the water storage box 30, and the top of the water storage box 30 is fixedly connected and connected to the water outlet head 304; When the water spray assembly is working, the cylinder 15 is fixed to the side of the extrusion chamber, and the extrusion head 2 is sleeved inside. The annular water spray head 151 is externally connected to a water pump, and the water pump fills the external liquid water into the annular water spray head 151. Then the annular water spray head 151 sprays liquid water and moves along the inner wall of the cylinder 15. Then, the particles cut by the hot cutter 35 flow with the liquid water when splashing onto the inner wall of the cylinder 15. When the 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 is attached to the inner wall of the cylinder 15. Therefore, the liquid flowing on the inner wall of the cylinder 15 The water enters the water box 30 through the water inlet 303. As the water box 30 rotates, centrifugal force is generated in the water box 30. Under the action of centrifugal force, the water push plate 301 inside the water box 30 adheres to the inner wall of the water box 30 on the side away from the center of the cylinder 15. The water box 30 drives the push rod 302 to rotate synchronously. The end of the push rod 302 outside the water box 30 will be intermittently squeezed by the triangular block 152 on the inner wall of the cylinder 15. The squeezing process is specifically that the end of the push rod 302 initially contacts the inclined surface of the triangular block 152, and then as the push rod 302 rotates, the end of the push rod 302 is squeezed by the inclined surface of the triangular block 152. The surface continues to be squeezed, so that the push rod 302 drives the water push plate 301 to move inside the water storage box 30 to overcome the centrifugal force, and the moving direction is toward the center of the cylinder 15. At this time, the water storage box 30 is already filled with liquid water. As the water push plate 301 moves, the liquid water inside the water storage box 30 will be sprayed out through the water outlet 304. The water outlet of the water outlet 304 points to the contact position between the blade of the hot cutter 35 and the extruder 2. When the push rod 302 passes over the triangular block 152, the water push plate 301 is reset under the action of centrifugal force, and the water storage box 30 repeats the water intake port 303. When it encounters the next triangular block 152, the above process is repeated;It should be pointed out that, during the movement of the water push plate 301, the water inlet 303 of the water storage box 30 will first spray out a small amount of liquid water, and then as the water push plate 301 passes over the water inlet 303, the liquid water inside the water storage box 30 is squeezed out and discharged only through the water outlet 304. The liquid water sprayed from the water outlet 304 acts on the contact position between the blade of the hot cutter 35 and the extruder head 2, thereby timely cooling the cut particles during the pelletizing process, so that the cut particles are quickly hardened, and the cut particles are prevented from splashing and contacting the hot cutter 35. 5. The liquid water sprayed from the water outlet 304 acts on the contact point between the hot cutter 35 and the extruder 2, preventing particles cut from the viscous raw material from adhering to the surface of the hot cutter 35 and preventing particles from accumulating on the surface of the hot cutter 35. This ensures that the hot cutter 35 remains stable during operation. Furthermore, the water inlet 303 of the water storage box 30 is located between the extruder 2 and the annular water spray head 151. Therefore, the cut particles will not enter the water inlet 303 along with the liquid water on the inner wall of the cylinder 15.

[0052] In summary, in the above embodiment of the present invention, a feed assembly is provided on one side of the hot cutter 35. Specifically, the feed assembly includes a cylinder 33.
