Description

Technical Field

[0001] The invention relates to the technical field of plastic particle preparation, in particular to a recycled plastic particle granulation device. Background Art

[0002] As a key equipment for material forming, the granulator transforms various raw materials into granular products with specific geometric shapes through mechanical processing. In the field of renewable resources, the plastic recycled granulator undertakes the core task of remaking waste plastics into standardized granules. Its operating stability directly determines the industrialization efficiency of recycled plastics.

[0003] Currently, traditional pelletizing equipment generally adopts a design scheme of centralized material storage in a top hopper. Operators need to put a large amount of crushed waste plastic into the hopper at one time, and the material slowly flows into the downstream extruder by its own weight. This operation mode has significant hidden dangers. Due to the complex sources of recycled plastics, they are often mixed with irregular fragments, dust and other foreign matter. The material fluidity varies or it becomes hardened due to moisture, which leads to a high probability of material flow interruption. Especially in the tapered transition zone of the hopper, the particles are very likely to mesh with each other to form a mechanical arch bridge. When a blockage occurs, the downstream screw is forced to slow down or even stop due to insufficient feed, and manual intervention is required to clear the hopper. Frequent production interruptions not only reduce equipment utilization, but also lead to process disorders such as melt temperature fluctuations and unbalanced extrusion pressure, seriously affecting the consistency of pellet quality.

[0004] At present, there is a plastic recycled granulator in the industry. By setting a horizontally sliding baffle at the cone at the bottom of the hopper, the discharge channel is periodically opened and closed to achieve batch discharge. This solution is expected to reduce the probability of blockage by reducing the instantaneous discharge volume, but it is found to be too ideal in actual application. When the material accumulation height in the hopper exceeds the critical value, usually more than 1.5 times the cone diameter, even if the baffle is removed from the discharge port, the upper material is still compacted by static pressure to form a stable mechanical arch structure. The horizontal transverse movement of the baffle can only release the bottom material and cannot destroy the bridging state of the upper layer. In order to avoid the risk of material breakage, the operator often passively prolongs the baffle opening time, resulting in a high material level in the hopper, which in turn increases the probability of bridging and forms a vicious circle. Therefore, the existing device still has defects in the transportation process of plastic particles, and is still insufficient in uniform feeding. It is difficult for the granulator to operate continuously and efficiently in a stable state, and the overall equipment efficiency and production capacity are affected. Summary of the Invention

[0009] The cam is connected to the top of the ladder by a plurality of levers, and the lever is connected to the top of the ladder by a plurality of levers, each of which is connected to the ladder by a plurality of levers.

[0010] Optionally, the shaking component includes a broken gear, which is fixedly connected to the shaft wall of the main shaft, and a rack row is fixedly connected to the surface of the ring. The teeth of the rack row are intermittently engaged with the teeth of the broken gear. In the initial state, the teeth of the broken gear face upward, and two resetters are fixedly connected to the inner wall of the mounting shell, and the connection ends of the two resetters are fixedly connected to the surface of the ring.

[0012] Optionally, the bridging avoidance component includes: a support plate, the support plate is fixedly connected to the inner wall of the granulator body, the two signal triggers are slidably connected to the surface of the support plate, and the two signal triggers are electrically connected to the signal driving device.

[0013] Optionally, two driving power supplies are fixedly connected to the inner wall of the mounting shell, and the output ends of the two driving power supplies are fixedly connected to the ends of the two main shafts respectively.

[0014] Optionally, the four baffles are all made of plastic, and the surfaces of the four baffles are all coated with a smooth coating.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention first adopts an intermittent feeding method, which can solve the problem of traditional material extrusion bit by bit. At the same time, compared with the ordinary intermittent feeding scheme, this measure can realize the quantitative granulation function. Through the quantitative control of granulation, the optimal and stable material level of the granulator body can be maintained, and the formula accuracy of the granulator body can be ensured. It fundamentally solves the fluctuation problem of the feeding link, can achieve a lower scrap rate and raw material waste, and better production data traceability, and avoid the large error in the proportion of plastic particles produced by the granulator body, and the possible inconsistency of color and performance between batches.

[0017] Second, the present invention will cause the corrugated pipe to shake during the process of conveying the plastic particles in the corrugated pipe, so that the plastic particles in the corrugated pipe can be dredged faster when conveying them into the granulator body, thereby enhancing the practicality of the device. At the same time, compared with the partial knocking and vibration method, this measure can also avoid the situation that the hard conveying pipe may be deformed due to long-term knocking in traditional measures, and also avoid the situation that a large force is needed to speed up the discharge efficiency. This measure can make the plastic particles enter the granulator body faster and more stably, which is convenient for the subsequent processing unit to prepare the plastic particles;

[0018] At the same time, by overshooting the teeth of the residual gear in the initial state, the teeth of the residual gear are made to form a right angle toward the connecting rod, so that when the two upper baffles are closed, the bellows has started to swing, and when the two lower baffles are closed, the resetter is used to reset the bellows, so that the bellows will not stop swinging immediately, and the practical effect is further improved.

[0019] 3. In the process of conveying the plastic particles in the hopper to the corrugated pipe, the present invention will also disconnect the contact positions of the two signal triggers. After receiving the disconnection command, the signal driving device drives the conveyor belt assembly, which can assist the plastic particles in the hopper to enter the corrugated pipe. In this way, since the side wall contact position of the plastic particles in the hopper is the contact position of the conveyor belt assembly, the occurrence of bridging phenomenon can be fundamentally avoided in this way, so that the internal space of the corrugated pipe is filled in each feeding process, so that the quantitative function of the feeding amount is ensured. The assurance of the quantitative function also provides a guarantee for the uniformity of the product quality such as the proportion and performance of the plastic particles produced by the granulator body. At the same time, this method is better than traditional processing methods such as patting and dredging. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1:

[0029] See also Figures 1 to 6 The present invention provides a recycled plastic granulation device, including a bracket 1, a granulator body 2 is mounted above the bracket 1, the granulator body 2 includes a feed port 3, a processing portion 31, a discharge portion 32 and a driving portion 33, a mounting shell 4 is provided above the feed port 3, a feed hopper 5 is fixedly connected to the top of the mounting shell 4, two partition plates 6 are fixedly connected to the inside of the mounting shell 4, the surfaces of the two partition plates 6 are both provided with openings, the openings on the opposite sides of the two partition plates 6 are fixedly connected to a bellows 7, the feed hopper 5 is connected to the feed port 3 through the bellows 7, two baffles 8 are slidably connected to the inside of the two partition plates 6, and a collar 9 is fixedly connected to the outer wall of the bellows 7, and further includes two groups of intermittent quantitative feeding components, two groups of shaking components and two groups of frames. The bridge avoidance component drives the two upper baffles 8 to move back and forth once, and then the two lower baffles 8 move back and forth again through the intermittent quantitative unloading component. The two sets of shaking components are used to drive the bellows 7 to shake when the two upper baffles 8 move. The two sets of bridge avoidance components are provided to assist the granular material in the hopper 5 to be unloaded when the two upper baffles 8 move, so as to avoid the bridge phenomenon. When in use, the plastic shell granular material is poured into the hopper 5, and the processing part 31 is driven to operate by the driving part 33 to granulate the plastic granules, and the prepared finished granules are discharged from the discharging part 32. The granulator body 2 is an existing device, and the specific granulation principle of the processing part 31 is no longer described in detail.

[0030] The intermittent quantitative feeding component includes a main shaft 10, the shaft wall of the main shaft 10 is fixedly connected to two connecting rods 11, the ends of the two connecting rods 11 are hinged with a roller 12, the interior of the two partition plates 6 is provided with two slide grooves 13, the groove walls of the four slide grooves 13 are slidably connected with hinge shafts 14, the four hinge shafts 14 are hinged with the side walls of the four baffles 8 respectively, and the inner wall of the mounting shell 4 is fixedly connected to two driving power supplies 30, the output ends of the two driving power supplies 30 are fixedly connected to the ends of the two main shafts 10 respectively, by starting the driving power supply 30, the main shaft 10 is driven to rotate, and the rotation of the main shaft 10 drives the two connecting rods 11 to rotate synchronously, so that the roller 12 is driven by the transmission of the two connecting rods 11 to perform a circular revolution with the main shaft 10 as the axis, and is in a state of being ... Figure 4 Status shown;

[0031] It also includes slot plate 15 and slot plate 2 16. The opposite sides of slot plate 15 and slot plate 2 16 are fixedly connected with hinge seats 17. The surfaces of the two hinge seats 17 are respectively hinged with two hinge rods 18. The ends of the four hinge rods 18 are respectively hinged with the axis walls of the four hinge shafts 14. The opposite sides of slot plate 15 and slot plate 2 16 are provided with push grooves 19. The roller 12 is located in the push grooves 19. Both ends of slot plate 15 and slot plate 2 16 are fixedly connected with connecting blocks 20. The four connecting blocks 20 are slidably connected to two limit rods 21 in a group of two. The two ends of the two limit rods 21 are fixedly connected to the inner wall of the mounting shell 4. The rod walls of the two limit rods 21 are respectively sleeved with two springs 22. The ends of the four springs 22 are fixedly connected to the inner wall of the mounting shell 4, and the ends of the four springs 22 are respectively fixedly connected to the surfaces of the four connecting blocks 20.

[0032] More specifically, in this embodiment: the roller 12 is rotated with the main shaft 10 as the axis. Figure 4 In the process of the counterclockwise revolution in the shown state, the upper slot plate 15 is first pushed upward. In this process, the movement of the slot plate 15 drives the connecting blocks 20 on both sides to move synchronously, so that the upper spring 22 is compressed. In this process, the two springs 22 at the bottom are not subject to external force and keep their positions unchanged, that is, the lower slot plate 2 16 maintains this vertical position. In the process of the slot plate 15 moving upward, the hinge seat 17 is synchronously driven to move upward, thereby pushing the two hinge rods 18 at the top to produce deflection through the hinge seat 17, thereby causing the two hinge shafts 14 connected thereto to move back to each other. This back-to-back displacement is limited by the slide slot 13. The back-to-back displacement of the two hinge shafts 14 can drive the two baffles 8 at the top to move back to each other, thereby opening the opening at the connection between the bellows 7 and the upper partition plate 6. At this time, the material in the hopper 5 enters the bellows 7 from here, so that the bellows 7 is filled with material.

[0033] As the roller 12 continues to move in a circular motion, the groove plate 15 is reset, and the two upper baffles 8 are relatively displaced, completing the sealing work of the loading amount of the bellows 7. During the continued revolution of the roller 12, it cooperates with the groove plate 2 16 below to repeat the movement consistent with the above principle, so that the two lower baffles 8 are displaced in opposite directions, and the opening at the connection between the bellows 7 and the lower partition plate 6 is opened, so that the material in the bellows 7 enters the feeding part 3, completing the loading work. After the loading is completed, the granulator body 2 prepares the plastic particles loaded at this stage, and the prepared plastic particles are discharged from the discharge part 32, thus completing the process of quantitative loading and quantitative granulation.

[0034] First, the intermittent feeding method can solve the problem of traditional material extrusion bit by bit. At the same time, compared with the ordinary intermittent feeding solution, this measure can realize the quantitative granulation function. Through the quantitative control of granulation, the optimal and stable material level of the granulator body 2 can be maintained, and the formula accuracy of the granulator body 2 can be ensured. This fundamentally solves the fluctuation problem of the feeding link, and can achieve a lower scrap rate and raw material waste, as well as better production data traceability, avoiding the large error in the proportion of plastic particles produced by the granulator body 2, and the possibility of inconsistent color and performance between batches.

[0035] The term "quantity" in this embodiment is intended to mean that the amount of material fed to the granulator body 2 is kept within a certain range each time, that is, the variation range is small, and it does not mean that the amount of material is kept consistent in grams.

[0036] Example 2, based on the above example:

[0037] See also Figures 3 to 6 The shaking component includes a broken gear 23, which is fixedly connected to the shaft wall of the main shaft 10. A rack row 24 is fixedly connected to the surface of the collar 9. The teeth of the rack row 24 are intermittently meshed with the teeth of the broken gear 23. In the initial state, the teeth of the broken gear 23 face upward. Two resetters 25 are fixedly connected to the inner wall of the mounting shell 4, and the connection ends of the two resetters 25 are fixedly connected to the surface of the collar 9.

[0038] More specifically, in this embodiment, during the rotation of the main shaft 10, the residual gear 23 is synchronously driven to rotate. When the teeth of the residual gear 23 engage with the teeth of the rack row 24, the rack row 24 is pushed to be displaced. The displacement of the rack row 24 then drives the collar 9 to move synchronously. The collar 9 causes the bellows 7 to shake. When the teeth of the residual gear 23 disengage from the teeth of the rack row 24, the reset device 25 resets the rack row 24, and the bellows 7 is synchronously reset.

[0039] By adopting this method, the plastic particles inside the corrugated tube 7 can be shaken, so that when the corrugated tube 7 is loaded into the granulator body 2, it can be dredged faster, thereby enhancing the practicality of the device. At the same time, compared with the partial knocking and vibration method, this measure can also avoid the situation that the hard conveying pipe may be deformed due to long-term knocking in traditional measures, and also avoid the situation that a large force is needed to speed up the discharge efficiency. This measure can make the plastic particles enter the granulator body 2 faster and more stably, which is convenient for the subsequent preparation process of plastic particles.

[0040] At the same time, by overtaking the teeth of the residual gear 23 in the initial state, the teeth of the residual gear 23 are made to form a right angle toward the connecting rod 11, so that when the two upper baffles 8 are closed, the bellows 7 has started to rock, and when the two lower baffles 8 are closed, the resetter 25 is used to reset the bellows 7, so that the bellows 7 will not stop rocking immediately, and the practical effect is further improved.

[0041] Example 3, based on the above example:

[0042] See also Figures 1 to 6 The bridge avoidance components include: a conveyor belt assembly 26, a mounting groove is provided on the side wall of the feed hopper 5, the conveyor belt assembly 26 is installed in the mounting groove, the outer wall of the feed hopper 5 is fixedly connected to a signal driving device 27 for driving the conveyor belt assembly 26, and the shaft walls of the two hinged shafts 14 located above are fixedly connected to signal triggers 28, and the trigger ends of the two signal triggers 28 are opposite to each other, and also include a support plate 29, the support plate 29 is fixedly connected to the inner wall of the granulator body 2, and the two signal triggers 28 are both slidably connected to the surface of the support plate 29, and the two signal triggers 28 are both electrically connected to the signal driving device 27.

[0043] More specifically, in this embodiment: when the two baffles 8 above are displaced in opposite directions, the two signal triggers 28 are driven to move synchronously through the synchronous movement of the two hinge shafts 14. At this time, the contact positions of the two signal triggers 28 are disconnected, and a signal instruction is sent to the signal driving device 27. After receiving the signal, the signal driving device 27 drives the conveyor belt assembly 26, which can assist the plastic particles in the hopper 5 to enter the bellows 7. By adopting this method, due to the contact position of the side wall of the plastic particles in the hopper 5, that is, the conveyor belt assembly 26 moves, the occurrence of bridging phenomenon will be fundamentally avoided, and the bellows 7 can be filled each time the material is loaded, so that the quantitative function of the loading amount is ensured. At the same time, this method is better than traditional processing methods such as patting and dredging.

[0044] Working principle: When the recycled plastic granulation device is used, the plastic shell granule material is poured into the hopper 5, and then the driving power supply 30 is started to drive the main shaft 10 to rotate, thereby driving the two connecting rods 11 to rotate synchronously, so that the roller 12 is driven by the two connecting rods 11 to perform a circular revolution with the main shaft 10 as the axis. At this time, the upper groove plate 15 is first pushed to move upward, and then the lower groove plate 2 16 is pushed downward, so as to realize the technical process of the upper two baffles 8 first moving back to back, and then the lower two baffles 8 moving back to back, so that the opening at the connection between the bellows 7 and the upper partition plate 6 is opened, and the material in the hopper 5 enters the bellows 7 from here, first filling the bellows 7 with material, and then opening the connection between the bellows 7 and the lower partition plate 6 is opened, so that the material in the bellows 7 enters the feed point 3, completing the granulation. The feeding work of the machine body 2 is completed. After the feeding is completed, the processing part 31 is driven to operate by starting the driving part 33. The plastic particles of the batch are granulated in the processing part 31, and the prepared finished particles are discharged from the discharging part 32. In this way, the process of quantitative feeding and quantitative granulation can be completed. This method can solve the problem of traditional material extrusion bit by bit. At the same time, compared with the ordinary intermittent feeding scheme, this measure can realize the quantitative granulation function. Through the quantitative control of granulation, the optimal stable material level of the granulator body 2 can be maintained, and the formula accuracy of the granulator body 2 can be ensured. The fluctuation problem of the feeding link is fundamentally solved, and a lower scrap rate and waste of raw materials can be achieved, as well as better traceability of production data. It avoids the large fluctuation of the amount of plastic particles received by the granulator body 2 per unit time, resulting in a large error in the proportion of the plastic particles produced, and the possible inconsistency of color and performance between batches.

[0045] During the rotation of the main shaft 10, the rack row 24 will also cause the bellows 7 to shake, so that the plastic particles in the bellows 7 can be transported to the granulator body 2 more quickly, thereby enhancing the practicality of the device. At the same time, compared with the partial knocking and vibration method, this measure can also avoid the situation that the hard conveying pipe may be deformed due to long-term knocking in traditional measures, and also avoid the situation that a large force is needed to speed up the discharge efficiency. This measure can make the plastic particles enter the granulator body 2 faster and more stably, which is convenient for the subsequent processing part 31 to prepare the plastic particles. At the same time, by overtaking the teeth of the residual gear 23 in the initial state, the teeth of the residual gear 23 are at a right angle to the connecting rod 11, so that when the two upper baffles 8 are closed, the bellows 7 has started to shake, and when the two lower baffles 8 are closed, the resetter 25 is used to reset the bellows 7, so that the bellows 7 will not stop shaking immediately, and the practical effect is further improved.

[0046] In the process of conveying the plastic particles in the hopper 5 to the bellows 7, the contact positions of the two signal triggers 28 will be disconnected. After receiving the disconnection command, the signal driving device 27 drives the conveyor belt assembly 26, which can assist the plastic particles in the hopper 5 to enter the bellows 7. By adopting this method, the side wall contact position of the plastic particles in the hopper 5, that is, the conveyor belt assembly 26 moves, which will fundamentally avoid the occurrence of bridging phenomenon. Each feeding process can fill the internal space of the bellows 7, so that the quantitative function of the feeding amount is ensured. The assurance of the quantitative function also provides a guarantee for the uniformity of the product quality such as the proportion and performance of the plastic particles produced by the granulator body 2. At the same time, this method is better than traditional processing methods such as patting and dredging.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
