Description

Technical Field

[0001] The present invention belongs to the technical field of plastic production, and specifically relates to a high-speed granulator. Background Art

[0002] Plastics are important organic synthetic polymer materials and are widely used. In the process of plastic product processing, granulators are often used. The granulator can extrude molten plastic through a specific mold and cut it into granular form for subsequent processing, storage, and transportation.

[0003] The patent with the publication number CN218948142U discloses a granulator, which includes a granulator main body, and also includes: a crushing mechanism and a screening mechanism. The top end of the granulator main body is fixedly connected to the bottom end of the crushing mechanism, and the bottom end of the screening mechanism is fixedly connected to the top end of the granulator main body; in this patent, the first motor drives the transmission rod to rotate, so that the spiral blade stirs the plastic raw material to move to the right. At the same time, the spiral blade heats the plastic raw material for melting. The spiral blade rotates and squeezes the molten plastic raw material against the extrusion plate, so that the molten plastic is discharged through the mesh holes on the extrusion plate. At the same time, the cooling water inlet pipe is connected to cooling water to cool the extrusion plate, so that the plastic raw material flowing through the extrusion plate is quickly cooled and solidified. The transmission rod drives the blade to rotate to cut the plastic flowing out of the extrusion plate into plastic particles of appropriate size, keeping the blade clean, which is beneficial to improving the quality and production efficiency of plastic particles.

[0004] However, the above technical solution still has the following deficiencies in actual application:

[0005] The cut plastic particles will accumulate in the same place. Usually, the cut plastic particles need to enter different processing procedures for processing. Moreover, the staff needs to reasonably distribute the plastic particles according to the total weight of the plastic particles to ensure that each procedure can obtain an appropriate amount of raw materials, so as to maintain the balance and efficient operation of the production line. If the plastic particles are piled up together, it is not conducive to this distribution work, and thus affects the normal progress of the subsequent processing procedures of the plastic particles.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The high-speed granulator described in the present invention utilizes a weight-controllable material distribution and collection mechanism. When a batch of plastic raw materials is completely pelletized, the plastic particles can be received by a receiving frame, and the total weight of the plastic particles can be obtained by using a weight sensor at the bottom thereof. The staff can formulate a reasonable distribution plan based on the total weight of the plastic particles, and use a push plate to push an appropriate number of plastic particles into the distributing frame based on the weight of the plastic particles that need to be collected at one time. If the weight of the plastic particles on the distributing frame is appropriate, the collection container can be placed at the lower end opening of the unloading frame to pour the plastic particles on the distributing frame into the unloading frame to complete the collection work. If the weight of the plastic particles on the distributing frame is less than the planned weight, the above operation can be repeated, and the push plate can be used again to push more plastic particles into the distributing frame. If the weight of the plastic particles on the distributing frame is greater than the planned weight, the push back plate can be used to push the excess plastic particles back into the receiving frame, thereby realizing the batch collection of the plastic particles, and each batch The weight of the plastic particles can be flexibly controlled to ensure that each collection container can obtain an appropriate amount of plastic particles, and then the collected plastic particles are transferred to the production line for processing, thereby ensuring the balance and efficient operation of the production line. In addition, when the number of plastic particles pushed is controlled, it is achieved by driving the push back plate and the push plate to move horizontally, and then changing from a straight state to a vertical state. Compared with inserting into the plastic particles from top to bottom to achieve separation of the plastic particles, this method will not cause the plastic particles to be crushed due to extrusion, thereby ensuring the quality of the plastic particles. In addition, when the dividing frame dumps the plastic particles, the push back plate can also be used to push the plastic particles to promote the falling of the plastic particles and prevent the plastic particles from adhering to the inside of the dividing frame. In addition, when the push back plate moves to the end of the dividing frame, the push back plate is flush with the end face of one side of the dividing frame, and the anti-sticking plate can be driven to move to form a scraping with the surface of the push back plate, which can further promote the falling of the plastic particles and prevent the plastic particles from adhering to the surface of the push back plate.

[0021] 2. The high-speed granulator described in the present invention can use the motor 5 to drive the stirring rod to rotate to stir the plastic raw materials after the plastic raw materials are added into the feed hopper, thereby improving the mixing effect of the plastic raw materials and further ensuring the quality and consistency of the plastic particles.

[0047] Specifically, when the existing granulator is in use, the cut plastic particles will be concentrated in the same place. Usually, the cut plastic particles need to enter different processing procedures for processing. Moreover, the staff needs to reasonably distribute the plastic particles according to the total weight of the plastic particles to ensure that each procedure can obtain an appropriate amount of raw materials, so as to maintain the balance and efficient operation of the production line. If the plastic particles are piled up together, it is not conducive to this distribution work, and thus affects the normal progress of the subsequent processing procedures of the plastic particles;

[0048] Therefore, to solve the above problems, in the use of this embodiment, the plastic raw material is added into the interior of the extrusion barrel 2 through the feed hopper 3. And the plastic raw material inside the extrusion barrel 2 is heated by the electric heating plate 29 to make it reach the molten state. Under the action of the sixth motor 32, the transmission rod 8 and the auger blade 33 rotate, so that the molten plastic raw material moves from left to right in the inner cavity of the extrusion barrel 2. And the cooling water in the cooling water tank 4 is pumped out to the cooling plate 6 by the pump body 7. After the cooling water moves in the inner cavity of the cooling plate 6, it will flow back to the cooling water tank 4 through the water outlet pipe 9. Thus, the plastic raw material in the right part of the inner cavity of the extrusion barrel 2 can be cooled and solidified. When the plastic raw material is extruded through the extrusion holes 13, under the action of the first motor 12 driving the blade 14 to rotate, the extruded plastic raw material can be cut by the blade 14, and plastic particles can be obtained. And the rotation speed of the blade 14 and the rotation speed of the transmission rod 8 are relatively fast, thus realizing high-speed granulation. The plastic particles will fall onto the material receiving frame 15. And at the initial state, the bottom of the partition plate 25 is in contact with the bottom of the material receiving frame 15. Therefore, the plastic particles will only be on the material receiving frame 15 and will not move into the material distribution frame 16. When all the plastic raw materials in a batch are granulated, the total weight of the plastic particles can be obtained through the weight sensor 17 at the bottom of the material receiving frame 15 and displayed by the display device. And a reasonable distribution plan can be formulated according to the total weight of the plastic particles. According to the weight of the plastic particles to be collected at one time, the seventh motor 34 can be used to drive the first threaded rod 36 to rotate, so that the partition plate 25 rises. At this time, the partition plate 25 no longer blocks the plastic particles. Then, the fourth motor 27 can be used to drive the fourth threaded rod 43 to rotate, so that the second slider 45 slides in the cavity of the material receiving frame 15, and the pushing plate 28 also moves horizontally. And because the groove of the material receiving frame 15 is relatively narrow, the plastic particles will not enter the cavity where the second slider 45 is located. When the pushing plate 28 moves horizontally to a suitable position, the tenth motor 44 is used to drive the pushing plate 28 to rotate 90 degrees, so that the horizontally placed pushing plate 28 becomes a standing state. At this time, driving the pushing plate 28 to approach the material distribution frame 16 again, the plastic particles on the right side of the pushing plate 28 can be pushed into the material distribution frame 16. At this time, the weight sensor 17 on the material distribution frame 16 detects the weight and displays the weight on the display device. And generally, it is not necessary to accurately control the weight of the plastic particles on the material distribution frame 16, and only within a reasonable range is required. If the weight of the plastic particles on the material distribution frame 16 is appropriate, the collection container can be placed at the lower opening of the blanking frame 19, and the electric push rod 20 is used to drive the material distribution frame 16 to descend, and the second motor 23 drives the material distribution frame 16 to rotate, so that the plastic particles on the material distribution frame 16 are poured into the blanking frame 19. The plastic particles will enter the collection container along with the blanking frame 19, and the collection work can be completed. And because the width of the bottom opening of the blanking frame 19 is relatively small, even a container with a small opening can realize the collection of plastic particles, avoiding the situation that plastic particles overflow the collection container when pouring plastic particles due to the small opening of the collection container.If the weight of the plastic particles on the material distribution frame 16 is less than the planned weight, the above operations can be repeated, and the pusher plate 28 can be used again to push more plastic particles onto the material distribution frame 16. If the weight of the plastic particles on the material distribution frame 16 is greater than the planned weight, the motor three 26 can be used to drive the rotation of the threaded rod three 41, so that the slider one 39 slides to adjust the position of the return push plate 18, and the motor nine 42 can be used to drive the rotation of the return push plate 18 to make the return push plate 18 stand up, and push the excess plastic particles back into the receiving frame 15. Thus, the batch collection of plastic particles is realized, and the weight of each batch of plastic particles can be flexibly controlled, so as to ensure that each collection container can obtain an appropriate amount of plastic particles. Then, the collected plastic particles are transported to the production line for processing, ensuring the balance and efficient operation of the production line. Moreover, when controlling the number of plastic particles pushed, it is achieved by driving the transverse movement of the return push plate 18 and the pusher plate 28 and then changing from a flat state to an upright state. Compared with inserting from top to bottom into the plastic particles to separate the plastic particles, this method will not cause the plastic particles to be crushed due to extrusion, ensuring the quality of the plastic particles;

[0049] Since some plastic particles may have a certain viscosity, when the plastic particles are poured from the material distribution frame 16 into the blanking frame 19, the plastic particles may adhere to the inner side of the material distribution frame 16, thus affecting the smooth progress of the blanking work. Therefore, to avoid this situation, when the material distribution frame 16 dumps the plastic particles, the return push plate 18 can also be used to push the plastic particles to promote the falling of the plastic particles and prevent the plastic particles from adhering to the inner side of the material distribution frame 16. Moreover, when the return push plate 18 moves to the end of the material distribution frame 16 and the return push plate 18 is flush with one side end face of the material distribution frame 16, the motor eight 40 can be used to drive the rotation of the threaded rod two 37 to move the anti-adhesion plate 24 to scrape the surface of the return push plate 18, which can further promote the falling of the plastic particles and prevent the plastic particles from adhering to the surface of the return push plate 18.

[0050] In this embodiment, as Figure 12 shown, a stirring rod 31 is rotatably arranged on one side of the upper end of the feed hopper 3, and a motor five 30 is fixedly connected to one side of the upper end of the feed hopper 3. The output end of the motor five 30 is fixedly connected to the stirring rod 31.

[0051] Specifically, when the plastic raw material is added to the feed hopper 3, the motor five 30 can be used to drive the rotation of the stirring rod 31 to stir the plastic raw material, thereby improving the mixing effect of the plastic raw material and ensuring the quality and consistency of the plastic particles.

[0052] Working principle: The plastic raw materials are added into the interior of the extrusion barrel 2 through the feed hopper 3. The stirring rod 31 is driven to rotate by the fifth motor 30 to stir the plastic raw materials, thereby improving the mixing effect of the plastic raw materials, and further ensuring the quality and consistency of the plastic particles. Moreover, the plastic raw materials inside the extrusion barrel 2 are heated by the electric heating plate 29 to reach the molten state. Under the action of the sixth motor 32, the transmission rod 8 and the auger blade 33 rotate, causing the molten plastic raw materials to move from left to right in the inner cavity of the extrusion barrel 2. Additionally, the cooling water in the cooling water tank 4 is pumped out to the cooling disc 6 by the pump body 7. After the cooling water moves in the inner cavity of the cooling disc 6, it will flow back to the cooling water tank 4 through the water outlet pipe 9, so as to cool and solidify the plastic raw materials in the right part of the inner cavity of the extrusion barrel 2. When the plastic raw materials are extruded through the extrusion holes 13, under the action of the first motor 12 driving the blade 14 to rotate, the extruded plastic raw materials are cut by the blade 14, and plastic particles can be obtained. Moreover, the rotation speed of the blade 14 and the rotation speed of the transmission rod 8 are relatively fast, thus realizing high-speed granulation;Plastic pellets will fall onto the material receiving frame 15. And initially, the bottom of the partition plate 25 is in contact with the bottom of the material receiving frame 15. Therefore, the plastic pellets will only be on the material receiving frame 15 and will not move into the material distribution frame 16. After a batch of plastic raw materials are all granulated, the total weight of the plastic pellets can be obtained through the weight sensor 17 at the bottom of the material receiving frame 15, and it will be displayed on the display device. And a reasonable distribution plan can be formulated according to the total weight of the plastic pellets. According to the weight of the plastic pellets that need to be collected at one time, the motor seven 34 can be used to drive the threaded rod one 36 to rotate, so that the partition plate 25 rises. At this time, the partition plate 25 no longer blocks the plastic pellets. Then, the motor four 27 can be used to drive the threaded rod four 43 to rotate, so that the slider two 45 slides in the cavity of the material receiving frame 15, and the pushing plate 28 also moves horizontally. And because the groove of the material receiving frame 15 is relatively narrow, the plastic pellets will not enter the cavity where the slider two 45 is located. When the pushing plate 28 moves horizontally to a suitable position, the motor ten 44 is used to drive the pushing plate 28 to rotate by 90 degrees, so that the horizontally placed pushing plate 28 becomes a standing state. At this time, by driving the pushing plate 28 to approach the material distribution frame 16, the plastic pellets on the right side of the pushing plate 28 can be pushed into the material distribution frame 16. At this time, the weight sensor 17 on the material distribution frame 16 detects the weight and displays it on the display device. And usually, there is no need to precisely control the weight of the plastic pellets on the material distribution frame 16, as long as it is within a reasonable range. If the weight of the plastic pellets on the material distribution frame 16 is appropriate, the collection container can be placed at the lower opening of the blanking frame 19, and the electric push rod 20 is used to drive the material distribution frame 16 to descend, and the motor two 23 drives the material distribution frame 16 to rotate, so that the plastic pellets on the material distribution frame 16 are poured into the blanking frame 19. The plastic pellets will then enter the collection container along with the blanking frame 19, and the collection work can be completed. And because the width of the bottom opening of the blanking frame 19 is relatively small, even a container with a small opening can be used to collect the plastic pellets, avoiding the situation where plastic pellets overflow the collection container when pouring the plastic pellets due to the small opening of the collection container;If the weight of the plastic particles on the material distribution frame 16 is less than the planned weight, the above operation can be repeated, and the pushing plate 28 can be used again to push more plastic particles onto the material distribution frame 16. If the weight of the plastic particles on the material distribution frame 16 is greater than the planned weight, the motor three 26 can be used to drive the rotation of the threaded rod three 41, so that the slider one 39 slides to adjust the position of the return push plate 18, and the motor nine 42 can be used to drive the return push plate 18 to rotate, so that the return push plate 18 stands up, and the excess plastic particles are pushed back into the receiving frame 15, thus realizing the flexible control of the weight of the plastic particles on the material distribution frame 16, and further ensuring that each collection container can obtain an appropriate amount of plastic particles. Then, the collected plastic particles are transported to the production line for processing, ensuring the balance and efficient operation of the production line. Moreover, when controlling the number of plastic particles pushed, it is achieved by driving the return push plate 18 and the pushing plate 28 to move horizontally and then change from a flat state to an upright state. Compared with inserting from top to bottom into the plastic particles to separate the plastic particles, this method will not cause the plastic particles to be crushed due to extrusion, ensuring the quality of the plastic particles. And because some plastic particles may have a certain viscosity, when the plastic particles are poured from the material distribution frame 16 into the blanking frame 19, the plastic particles may adhere to the inner side of the material distribution frame 16, thus affecting the smooth progress of the blanking work. Therefore, to avoid this situation, when the material distribution frame 16 pours the plastic particles, the return push plate 18 can also be used to push the plastic particles to promote the falling of the plastic particles and prevent the plastic particles from adhering to the inner side of the material distribution frame 16. Moreover, when the return push plate 18 moves to the end of the material distribution frame 16 and the return push plate 18 is flush with one end face of the material distribution frame 16, the motor eight 40 can be used to drive the rotation of the threaded rod two 37 to move the anti-adhesion plate 24 to scrape the surface of the return push plate 18, which can further promote the falling of the plastic particles and prevent the plastic particles from adhering to the surface of the return push plate 18.;
