Description

Technical Field

[0001] This utility model relates to the field of granulator technology, specifically a pelletizing device for a granulator. Background Technology

[0002] A pelletizer is a molding machine used to shape materials into specific shapes. In the rubber production industry, rubber raw materials processed by pelletizers need to be pelletized for subsequent use of rubber granules, thus requiring a pelletizing device.

[0003] A Chinese patent with authorization announcement number CN222645050U discloses a granulation and cutting mechanism, including a first plate and a second plate connected by a side plate. The first plate has a detachable first opening with a template. A motor is located on one side of the second plate, and the motor's output shaft extends through the second plate into a housing. The output shaft is connected to a blade to drive the blade to rotate. The side plate has a second opening and a cover plate that covers the second opening. The template is detachably connected to the first opening via a connector that engages with a first and second annular groove, facilitating template replacement and enabling the production of granules with different diameters.

[0004] However, the cutting mechanism mentioned above still has some problems. During the granulation process, the temperature of the freshly cut plastic granules is high. After initial cooling, they still have a certain degree of stickiness. The granules are easy to come into contact with each other and stick together. After the granules agglomerate into lumps, it will affect the quality of the granules. Therefore, a pelletizing device for a granulator is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve the problems mentioned in the background art, this utility model proposes a pelletizing device for a pelletizer.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A pelletizing device for a pelletizer, comprising two symmetrically arranged support legs, a pelletizing cylinder mounted on the top side of the support legs, a connecting cylinder mounted on the outer side of one end of the pelletizing cylinder, and a receiving cylinder connected to the bottom side of the connecting cylinder. The receiving cylinder is rectangular, with grooves on both sides. A connecting plate is slidably mounted inside the grooves, and the connecting plate has several fine holes inside. The length of the connecting plate is greater than the length of the receiving cylinder. A fixing plate is fixedly connected to one side of the connecting plate. Two connecting rods are symmetrically fixedly connected to one side of the receiving cylinder, with one end of each connecting rod slidably penetrating the fixing plate. The connecting rods share a common... A limiting plate is installed, with tension springs fixed to both ends of the limiting plate and the fixing plate. The tension springs are sleeved on the outside of the connecting rod. An mounting plate is installed on the other side of the receiving cylinder, and a drive motor is installed on the bottom side of the mounting plate. A cam is installed on the output end of the drive motor. When the cam is in operation, its protruding position will contact the other end of the connecting plate. A discharge gate is installed on one side of the receiving cylinder through a hinge. The connecting plate reciprocates under the action of the cam, thereby causing the particles to vibrate in the receiving cylinder, preventing the particles from accumulating and agglomerating. The fine holes are not only used for the discharge of cold air, but also for the further cooling of the particles while the particles are vibrating and dispersing, preventing the particles from agglomerating due to high temperature and improving the quality and dispersibility of the particles.

[0007] Preferably, a feed hopper is installed on the top side of the other end of the granulation cylinder, a conveyor motor is installed on one side of the granulation cylinder, a rotating shaft is installed at the output end of the conveyor motor, one end of the rotating shaft passes through the granulation cylinder, and an extrusion screw is installed on the outside of the rotating shaft, which realizes the continuous extrusion operation of the granules, ensuring that the raw materials can enter the granulation cylinder uniformly and stably, and form granules through the extrusion action of the screw.

[0008] Preferably, an installation cavity is installed on the top side of the connecting cylinder, and a negative pressure motor is installed on the top side of the installation cavity. The output end of the negative pressure motor extends into the interior of the installation cavity and is equipped with three fan blades. An air inlet pipe is connected to the top side of the installation cavity. A cold storage plate is detachably installed inside the middle of the installation cavity. An air outlet pipe is installed on the bottom side of the installation cavity. One end of the air outlet pipe extends into the interior of the connecting cylinder and is connected to an annular pipe. Several air nozzles are equidistantly installed on the inner side of the annular pipe. The negative pressure motor drives the fan blades to rotate, generating negative pressure to draw in cold air. After the cold air is cooled by the cold storage plate, it is blown towards the pelletizing area through the air outlet pipe and the air nozzles on the annular pipe to rapidly cool the raw material that has just exited the pelletizing hole.

[0009] Preferably, a cutting motor is installed on one side of the connecting cylinder, and a rotating shaft is installed at the output end of the cutting motor. Six convex grooves are equally spaced inside one end of the rotating shaft. A convex slider is slidably installed inside the convex grooves. An arc-shaped plate is installed on the top side of the convex slider. A cutting blade is mounted on the top side of the arc-shaped plate. Locking screws are installed at both ends of the arc-shaped plate on both sides of the cutting blade. Several granulation holes are opened on one side of the granulation cylinder. The cutting blade can be easily disassembled, repaired, or replaced. When the cutting blade is worn or damaged, it is not necessary to disassemble the entire cutting device. The cutting blade can be removed from the arc-shaped plate for replacement simply by loosening the locking screws.

[0010] Preferably, both the connecting cylinder and the mounting cavity are openable structures, which facilitates the placement and removal of the cold storage plate and the cutting blade.

[0011] Preferably, a control panel is installed on one side of the support leg. The control panel is used to control the operation of the electrical components inside the device, thereby realizing centralized operation and control of the electrical components inside the device.

[0012] The advantages of this utility model are:

[0013] 1. The present invention drives the motor to rotate the cam at its output end. When the cam's protruding position contacts the connecting plate, it pushes the connecting plate to slide in the groove. The fixed plate moves with the connecting plate, and the tension spring is stretched. When the cam's protruding position leaves the connecting plate, the connecting plate returns to its original position under the elastic force of the tension spring. The connecting plate reciprocates under the action of the cam. The reciprocating motion of the connecting plate drives the particles in the receiving cylinder to vibrate, preventing particle accumulation and agglomeration, and improving the quality and dispersibility of the particles.

[0014] 2. This utility model starts the cutting motor, which drives the shaft at its output end to rotate. The rotating cutting blade cuts the strip-shaped raw material that has been squeezed out of the particle outlet and cooled and solidified into granules. When the cutting blade is worn or damaged, since both ends of the arc plate are equipped with locking screws on both sides of the cutting blade, the operator only needs to loosen the locking screws to remove the cutting blade from the arc plate for replacement without disassembling the entire cutting device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4As shown, a pelletizing device for a pelletizer includes two symmetrically arranged support legs 1. A pelletizing cylinder 2 is mounted on the top side of the support legs 1. A connecting cylinder 3 is mounted on the outer side of one end of the pelletizing cylinder 2. A receiving cylinder 4 is connected to the bottom side of the connecting cylinder 3. The receiving cylinder 4 is rectangular in shape and has grooves on both sides. A connecting plate 5 is slidably mounted inside the grooves. The connecting plate 5 has several fine holes inside and its length is greater than the length of the receiving cylinder 4. A fixing plate 6 is fixedly connected to one side of the connecting plate 5. Two connecting rods 7 are symmetrically fixed to one side of the receiving cylinder 4. One end of each connecting rod 7 slides through the fixed plate 6. A limiting plate 8 is installed on one end of each connecting rod 7. Tension springs 9 are fixed to both ends of the limiting plate 8 and the fixed plate 6. The tension springs 9 are sleeved on the outside of the connecting rod 7. An mounting plate 10 is installed on the other side of the receiving cylinder 4. A drive motor 11 is installed on the bottom side of the mounting plate 10. A cam 12 is installed at the output end of the drive motor 11. When the cam 12 is in operation, its protruding position contacts the other end of the connecting plate 5. A discharge gate 13 is installed on one side of the receiving cylinder 4 via a hinge. A control panel is installed on one side of the support leg 1. 34; During operation, the freshly cut plastic granules are at a high temperature during the granulation process. Even after initial cooling, they still retain a certain degree of stickiness, making it easy for the granules to come into contact with each other and stick together. This clumping of granules affects their quality. The cut granules fall into the connecting cylinder 3, which prevents granule splashing. The granules then fall into the receiving cylinder 4. The drive motor 11 is activated via the control panel 34, causing the cam 12 at its output end to rotate. During operation, the raised portion of the cam 12 contacts the other end of the connecting plate 5. When the raised portion of the cam 12 contacts the connecting plate 5, it pushes the connecting plate... 5 slides in the groove. At this time, the fixed plate 6 moves together with the connecting plate 5, and the tension spring 9 is stretched. When the protruding position of the cam 12 leaves the connecting plate 5, the connecting plate 5 returns to its original position under the elastic force of the tension spring 9. In this way, the connecting plate 5 reciprocates under the action of the cam 12. The reciprocating motion of the connecting plate 5 drives the particles in the receiving cylinder 4 to vibrate, preventing the particles from accumulating and agglomerating. At the same time, the several fine holes opened inside the connecting plate 5 are not only used for the discharge of cold air, but also for the particles to be cooled again while vibrating and dispersing the material, so as to prevent the particles from agglomerating due to high temperature, thereby improving the quality and dispersibility of the particles.

[0024] After the granules have completed oscillation and cooling in the receiving cylinder 4, they can be discharged from the receiving cylinder 4 through the discharge gate 13, completing the entire granulation and pelletizing process. During the pelletizing process, the discharge gate 13 is always open to avoid affecting the oscillation operation of the granules.

[0025] Please see Figure 1 , 2As shown in Figures 3 and 5, a feed hopper 14 is installed on the top side of the other end of the granulation cylinder 2, a conveying motor 15 is installed on one side of the granulation cylinder 2, a rotating shaft 16 is installed at the output end of the conveying motor 15, one end of the rotating shaft 16 passes through the granulation cylinder 2, and an extrusion screw 17 is installed on the outside of the rotating shaft 16.

[0026] The top side of the connecting cylinder 3 is equipped with an installation cavity 18, and a negative pressure motor 19 is installed on the top side of the installation cavity 18. The output end of the negative pressure motor 19 extends into the interior of the installation cavity 18 and is equipped with three fan blades 20. An air inlet pipe 21 is connected to the top side of the installation cavity 18. A cold storage plate 22 is detachably installed inside the middle of the installation cavity 18. An air outlet pipe 23 is installed on the bottom side of the installation cavity 18. One end of the air outlet pipe 23 extends into the interior of the connecting cylinder 3 and is connected to an annular pipe 24. Several air nozzles 25 are installed at equal intervals on the inner side of the annular pipe 24.

[0027] A cutting motor 26 is installed on one side of the connecting cylinder 3. A rotating shaft 27 is installed at the output end of the cutting motor 26. Six convex grooves 28 are equally spaced inside one end of the rotating shaft 27. A convex slider 29 is slidably installed inside the convex grooves 28. An arc plate 30 is installed on the top side of the convex slider 29. A cutting blade 31 is assembled on the top side of the arc plate 30. Locking screws 32 are installed at both ends of the arc plate 30 on both sides of the cutting blade 31. A plurality of granulation holes 33 are opened on one side of the granulation cylinder 2.

[0028] Both the connecting cylinder 3 and the mounting cavity 18 are openable structures. During operation, the granulator is a molding machine used to shape materials into specific shapes. In the rubber production industry, rubber raw materials processed by the granulator need to be pelletized for subsequent use as rubber granules. Therefore, a pelletizing device is required. The operator starts the conveyor motor 15 via the control panel 34. The conveyor motor 15 drives the rotating shaft 16 at its output end to rotate, and the extrusion screw 17 rotates accordingly. At this time, the raw material is fed into the granulation cylinder 2 from the feed hopper 14. As the extrusion screw 17 rotates, the raw material is continuously squeezed forward within the granulation cylinder 2, and finally extruded through several pelletizing holes 33 on one side of the granulation cylinder 2, forming strip-shaped plastic raw material, preparing for subsequent pelletizing.

[0029] Simultaneously, the negative pressure motor 19 is started, and the three fan blades 20 at its output end are driven to rotate at high speed in the mounting cavity 18, generating negative pressure. Under the action of negative pressure, the outside air is drawn into the mounting cavity 18 through the air inlet pipe 21. The drawn-in air passes through the detachable cold storage plate 22, which cools the air and turns it into cold air. The cold air enters the annular pipe 24 through the air outlet pipe 23, and then blows from several air nozzles 25 onto the raw material extruded from the particle outlet hole 33, rapidly cooling the freshly extruded raw material and making it solidify quickly, which is convenient for subsequent cutting.

[0030] Start the cutting motor 26, which drives the rotating shaft 27 at its output end to rotate. The rotating cutting blade 31 cuts the strip-shaped raw material that has been squeezed out from the particle outlet 33 and cooled and solidified into granules. When the cutting blade 31 is worn or damaged, since both ends of the arc plate 30 are equipped with locking screws 32 on both sides of the cutting blade 31, the operator only needs to loosen the locking screws 32 to remove the cutting blade 31 from the arc plate 30 for replacement without disassembling the entire cutting device.

[0031] Since both the connecting cylinder 3 and the mounting cavity 18 are openable structures, when the cold storage plate 22 needs to be replaced, the mounting cavity 18 can be opened for easy loading and unloading operations; when the cutting blade 31 needs to be disassembled, repaired or replaced, the connecting cylinder 3 can be opened for direct operation, which improves the convenience of equipment maintenance.

[0032] Working principle: The operator starts the conveyor motor 15 via the control panel 34. The conveyor motor 15 drives the rotating shaft 16 at its output end to rotate, and the extrusion screw 17 rotates accordingly. At this time, the raw material is fed into the granulation cylinder 2 from the feed hopper 14. As the extrusion screw 17 rotates, the raw material is continuously squeezed forward in the granulation cylinder 2, and finally extruded through several granulation holes 33 opened on one side of the granulation cylinder 2 to form strip-shaped plastic raw material, which is prepared for subsequent pelletizing.

[0033] Simultaneously, the negative pressure motor 19 is started, and the three fan blades 20 at its output end are driven to rotate at high speed in the mounting cavity 18, generating negative pressure. Under the action of negative pressure, the outside air is drawn into the mounting cavity 18 through the air inlet pipe 21. The drawn-in air passes through the detachable cold storage plate 22, which cools the air and turns it into cold air. The cold air enters the annular pipe 24 through the air outlet pipe 23, and then blows from several air nozzles 25 onto the raw material extruded from the particle outlet hole 33, rapidly cooling the freshly extruded raw material and making it solidify quickly, which is convenient for subsequent cutting.

[0034] Start the cutting motor 26, which drives the rotating shaft 27 at its output end to rotate. The rotating cutting blade 31 cuts the strip-shaped raw material that has been squeezed out from the particle outlet 33 and cooled and solidified into granules. When the cutting blade 31 is worn or damaged, since both ends of the arc plate 30 are equipped with locking screws 32 on both sides of the cutting blade 31, the operator only needs to loosen the locking screws 32 to remove the cutting blade 31 from the arc plate 30 for replacement without disassembling the entire cutting device.

[0035] The cut particles fall into the connecting cylinder 3, which prevents the particles from splashing. Then the particles fall into the receiving cylinder 4. The drive motor 11 is started through the control panel 34. The drive motor 11 drives the cam 12 at its output end to rotate. When the cam 12 is working, its protruding position will contact the other end of the connecting plate 5. When the protruding position of the cam 12 contacts the connecting plate 5, it pushes the connecting plate 5 to slide in the groove. At this time, the fixing plate 6 moves with the connecting plate 5, and the tension spring 9 is stretched. When the protruding position of the cam 12 leaves the connecting plate 5, the connecting plate 5 returns to its original position under the elastic force of the tension spring 9. In this way, the connecting plate 5 reciprocates under the action of the cam 12. The reciprocating motion of the connecting plate 5 drives the particles in the receiving cylinder 4 to vibrate, preventing the particles from accumulating and agglomerating. At the same time, the several fine holes opened inside the connecting plate 5 are not only used for the discharge of cold air, but also for the particles to be cooled again while vibrating and dispersing, preventing the particles from agglomerating due to high temperature, thus improving the quality and dispersibility of the particles.

[0036] After the granules have completed oscillation and cooling in the receiving cylinder 4, they can be discharged from the receiving cylinder 4 through the discharge gate 13, completing the entire granulation and pelletizing process. During the pelletizing process, the discharge gate 13 is kept open to avoid affecting the oscillation operation of the granules.

[0037] Since both the connecting cylinder 3 and the mounting cavity 18 are openable structures, when the cold storage plate 22 needs to be replaced, the mounting cavity 18 can be opened for easy loading and unloading operations; when the cutting blade 31 needs to be disassembled, repaired or replaced, the connecting cylinder 3 can be opened for direct operation, which improves the convenience of equipment maintenance.
