Description

Technical Field

[0001] This invention relates to the field of plastic recycling and processing, and more specifically, to a waste plastic recycling and granulation device. Background Technology

[0002] As the consumption of plastic products continues to increase, the amount of waste plastic is also increasing. The main types of waste plastic are plastic film, plastic filaments and woven products, foam plastic, plastic packaging boxes and containers, daily plastic products, plastic bags and agricultural mulch film. These products become one of the important sources of waste plastic after they are scrapped. In order to save resources, waste plastic is generally recycled and reused, which can also reduce environmental pollution.

[0003] The process of recycling plastic granulation involves crushing, plasticizing and extruding, filtering into strips, cooling and drying, and finally pelletizing to complete the reprocessing and granulation of waste plastic. Currently, the extruder of the granulator directly extrudes and plasticizes the crushed plastic particles that enter the hopper.

[0004] Chinese Patent No. CN219095595U discloses a waste plastic recycling granulation device. The cutting blade rotates to cut long strips of material, and the cut plastic granules fall into a collection box for collection. The cutting blade can cut and granulate the plastic raw material immediately and in a timely manner, avoiding the occurrence of cutting gaps that would cause the plastic raw material to solidify and form, making the cutting process more troublesome. This further improves the overall granulation efficiency of the device.

[0005] While the aforementioned patents can improve work efficiency, they still have the following shortcomings:

[0006] During the plastic recycling and granulation process, the molten plastic is extruded into strips. At this point, the plastic is soft due to the high temperature, making it easy to cut. However, this soft plastic tends to adhere to the surface of the cutting blade. As the cutting operation continues, this adhered plastic gradually cools and comes into contact with air, causing it to solidify and harden. This hardened plastic accumulates on the blade, affecting the smoothness and precision of the cut, resulting in a decrease in cutting quality over time. To maintain cutting efficiency and quality, the machine must be stopped periodically for blade cleaning. This maintenance process is not only time-consuming but also reduces overall work efficiency.

[0007] Therefore, a waste plastic recycling and granulation device is proposed. Summary of the Invention

[0008] To address the problems existing in the prior art, the purpose of this invention is to provide a waste plastic recycling and granulation device that can reduce the probability of plastic adhering to the surface of the cutting blade, reduce maintenance frequency, and ensure work efficiency.

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] A waste plastic recycling and granulation device includes a worktable, an extruder mounted on the worktable, a mold mounted on the output end of the extruder, and further includes:

[0011] The cutting mechanism includes a motor, a mounting plate on the output end of the motor, and cutting blades evenly mounted on the mounting plate. The cutting blades cooperate with the mold, and a stabilizing sleeve is mounted on multiple cutting blades.

[0012] The cleaning mechanism includes a cavity formed on the stabilizing sleeve, with drainage holes evenly distributed on the side wall of the cavity, each drainage hole corresponding to a cutting blade. A water supply component that mates with the cavity is provided on the worktable, a control component that mates with the drainage holes is provided on the worktable, and a heating component that mates with the cavity is provided on the worktable.

[0013] The grinding mechanism includes a material box located above the water tank, which is filled with iron sand. A valve is installed on the output end of the material box, and the output end of the material box is connected to the output end of the water tank.

[0014] In this process, the raw material discharged from the mold is cut by a cutting blade to complete granulation. During the cutting process, the water discharged from the cavity impacts the surface of the cutting blade. Furthermore, through the cooperation of the heating and control components, the water temperature discharged from the drain hole is increased, while the impact force of the water flow discharged from the drain hole is also increased.

[0015] The raw material is heated, melted, and extruded through an extruder and a mold. Then, the strip-shaped plastic is cut into granules by a motor that drives the mounting plate and the cutting blade to rotate rapidly. By fixing the cutting blade to the stabilizing sleeve, the drainage hole can always be aligned with the cutting blade, which can achieve precise cleaning of the cutting blade.

[0016] After cutting, the cutting blade continues to rotate. As the cutting blade moves away from the mold, water is drained through the drain hole onto the cutting blade surface by the water supply component. With the cooperation of the control component, the impact force of the water discharged from the drain hole is increased, thereby cleaning the plastic adhering to the cutting blade surface. This cleans the cutting blade, reducing downtime for maintenance. Furthermore, the opening and closing of the control valve can control whether iron sand in the material box mixes with the water in the cavity. When the valve is open, the iron sand flows with the water flow. Therefore, when the water flow impacts the cutting blade surface, the friction between the iron sand and the cutting blade can polish the cutting blade, ensuring that the cutting blade remains sharp.

[0017] Furthermore, the water supply assembly includes a water tank mounted on a workbench, an annular groove is provided on the side wall of the cavity, a sealing ring is movably mounted in the annular groove, the annular groove and the sealing ring cooperate, and the output end of the water tank passes through the sealing ring.

[0018] Furthermore, the control assembly includes a fixed magnet fixedly mounted on the surface of the mold, a movable magnet slidably mounted inside the cavity, a sealing gasket that mates with the drain hole mounted on the surface of the movable magnet, and an elastic element mounted between the movable magnet and the cavity sidewall support.

[0019] Furthermore, it includes a cooling box used to cool and solidify the cut plastic granules;

[0020] The heating assembly includes a guide plate that is inclinedly installed on the top wall of the cooling tank. The guide plate has a guide groove, and a water cavity is formed on the surface of the guide groove. A heat-conducting plate covering the surface of the water cavity is fixedly installed in the guide groove. A hot water pipe with its top end connected to the water tank is inserted into the top wall of the water cavity.

[0021] Furthermore, a guide rod is installed on the surface of the cutting blade, and a scraper is slidably mounted on the guide rod. An elastic rope is installed between the scraper and the mounting plate, and the elastic rope is used to drive the scraper to move.

[0022] The mounting plate drives the cutting blade to rotate rapidly. Under the action of centrifugal force, the scraper moves along the guide rod to the end away from the mounting plate, and the elastic rope is in a stretched state. When the work is completed and the cutting blade stops rotating, the elastic rope pulls the scraper back to its original position. During this process, the scraper scrapes the surface of the cutting blade, thereby cleaning away the soft plastic residue remaining on the surface of the cutting blade in a timely manner.

[0023] Furthermore, a groove is provided on the side wall of the scraper near the cutting blade, a pressure chamber is provided on the elastic rope, and a hole is provided on the side wall of the groove, which is connected to the pressure chamber.

[0024] During the recovery process of the elastic rope made of rubber, the gas in the pressurized chamber enters the groove through the hole. At this time, the groove is under high pressure and the gas in the groove is discharged through the gap between the scraper and the cutting blade. This prevents solid materials from entering the gap between the cutting blade and the scraper and jamming the scraper, thus ensuring that the scraper can be reset normally.

[0025] Furthermore, a through groove is horizontally opened on the surface of the heat-conducting plate, and an elastic membrane is fixedly installed in the through groove. The elastic membrane is used to reduce the impact force on the plastic particles.

[0026] Furthermore, a drain valve is provided on the hot water pipe, and an inlet pipe extending into the water tank is inserted into the side wall of the water cavity, with an inlet valve on the inlet pipe.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] (1) This solution sets up a cavity, a drain hole, a moving magnet, and a fixed magnet. When the cavity drives the moving magnet to rotate to the mold surface to cut plastic particles, the moving magnet drives the sealing gasket to move to the surface of the drain hole. At this time, the drain hole on the mold surface will be blocked by the sealing gasket, thereby reducing the number of drain holes that can drain water. Therefore, the impact force of the water flow discharged from the drain hole in the drain state is increased, which improves the impact effect on the cutting blade. In addition, by blocking the drain hole on the mold surface, water flow can be prevented from spraying onto the surface of the plastic strip to be cut, ensuring that the plastic strip remains soft and reducing the wear of the cutting blade.

[0029] (2) This scheme sets up a guide plate, a water cavity, a heat conduction plate, and a hot water pipe. The high-temperature plastic particles that are cut first fall onto the surface of the guide plate and then move down along the inclined guide plate. During the movement of the plastic particles, the heat of the plastic particles is transferred to the water in the water cavity through the heat conduction plate. At this time, the water temperature rises. Since the water with a higher temperature will automatically flow upward, the hot water in the water cavity will flow into the water tank along the hot water pipe, thus providing hot water to the water tank and initially cooling the plastic particles.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Example 1:

[0041] Please see Figures 1 to 7 A waste plastic recycling and granulation device includes a workbench, an extruder 1 mounted on the workbench, a mold 2 mounted on the output end of the extruder 1, and further includes:

[0042] The cutting mechanism includes a motor 3, an installation plate 4 is provided on the output end of the motor 3, and cutting blades 5 are evenly installed on the installation plate 4. The cutting blades 5 cooperate with the mold 2, and a stabilizing sleeve 6 is installed on multiple cutting blades 5.

[0043] The cleaning mechanism includes a cavity 7 formed on the stabilizing sleeve 6, with drainage holes 8 evenly formed on the side wall of the cavity 7, each drainage hole 8 corresponding to a cutting blade 5. A water supply assembly that cooperates with the cavity 7 is provided on the worktable, a control assembly that cooperates with the drainage holes 8 is provided on the worktable, and a heating assembly that cooperates with the cavity 7 is provided on the worktable.

[0044] The grinding mechanism includes a material box 9 disposed above the water tank 12, the material box 9 being filled with iron sand 10, and a valve 11 installed on the output end of the material box 9, the output end of the material box 9 being connected to the output end of the water tank 12;

[0045] In this process, the raw material discharged from the mold 2 is cut by the cutting blade 5 to complete the granulation. During the cutting process, the water discharged from the cavity 7 impacts the surface of the cutting blade 5. Furthermore, through the cooperation of the heating component and the control component, the water temperature discharged from the drain hole 8 is increased, and the impact force of the water flow discharged from the drain hole 8 is also increased.

[0046] During the processing, the raw material is heated and melted by the extruder 1, and then the strip plastic with a high temperature is extruded through the small hole on the mold 2. The strip plastic is then cut into granules by the motor 3 driving the mounting plate 4 and the cutting blade 5 to rotate quickly. By fixing the cutting blade 5 to the stabilizing sleeve 6, the drain hole 8 can always be aligned with the cutting blade 5, which plays a role in accurately cleaning the cutting blade 5.

[0047] After cutting, the cutting blade 5 continues to rotate. When the cutting blade 5 moves away from the mold 2, water can drain through the drain hole 8 onto the surface of the cutting blade 5 under the action of the water supply component. With the cooperation of the control component, the impact force of the water discharged from the drain hole 8 can be increased, thereby cleaning the plastic adhering to the surface of the cutting blade 5. Under the action of the heating component, the water discharged from the drain hole 8 is hot water, which prevents the plastic adhering to the surface of the cutting blade 5 from cooling and solidifying and fixing itself to the surface of the cutting blade 5. Therefore, the cutting blade 5 can be cleaned, reducing the number of downtime maintenance and improving work efficiency. Furthermore, the opening and closing of the control valve 11 can control whether the iron sand 10 in the material box 9 is mixed into the water in the cavity 7. When the valve 11 is open, the iron sand 10 flows with the water flow. Therefore, when the water flow impacts the surface of the cutting blade 5, the friction between the iron sand 10 and the cutting blade 5 can polish the cutting blade 5, ensuring that the cutting blade 5 remains sharp.

[0048] Since the iron sand 10 can be attracted by a magnet, after processing, the iron sand 10 mixed in with the plastic particles can be separated from the plastic particles by the magnet, which facilitates operation; and by keeping the material box 9 in a sealed state, the water discharged from the water tank 12 can be prevented from entering the material box 9.

[0049] like Figure 1 , Figure 4 As shown, the water supply assembly includes a water tank 12 set on the workbench. An annular groove is provided on the side wall of the cavity 7. A sealing ring 13 is movably arranged in the annular groove. The annular groove and the sealing ring 13 are dynamically matched. The output end of the water tank 12 passes through the sealing ring 13.

[0050] By adopting the above technical solution, during the cutting process, by setting a water pump in the water tank 12, the water in the water tank 12 can be discharged into the cavity 7 through the output end of the water tank 12 when the water pump is started, thus providing water to the cavity 7. Furthermore, by making the sealing ring 13 slide in the annular groove, the normal rotation of the stabilizing sleeve 6 can be ensured, which in turn ensures that the cutting blade 5 can rotate normally.

[0051] like Figure 4As shown, the control assembly includes a fixed magnet 14 fixedly mounted on the surface of the mold 2, a movable magnet 15 slidably mounted in the cavity 7, a sealing gasket 16 that mates with the drain hole 8 mounted on the surface of the movable magnet 15, and an elastic element 17 mounted on the movable magnet 15 and the side wall support of the cavity 7.

[0052] By adopting the above technical solution, when the cavity 7 drives the moving magnet 15 to rotate to the surface of the mold 2 to cut plastic particles, the attraction between the fixed magnet 14 and the moving magnet 15 can overcome the elastic force of the elastic element 17. At this time, the moving magnet 15 drives the sealing gasket 16 to move to the surface of the drain hole 8. At this time, the drain hole 8 located on the surface of the mold 2 will be blocked by the sealing gasket 16, thereby reducing the number of drain holes 8 that can drain water. Therefore, the impact force of the water flow discharged from the drain hole 8 in the draining state is increased, and the impact effect on the cutting blade 5 is improved.

[0053] Furthermore, by blocking the drainage holes 8 located on the surface of the mold 2, water can be prevented from spraying onto the surface of the plastic strip to be cut, ensuring that the plastic strip remains soft and reducing the wear of the cutting blade 5.

[0054] like Figure 1 , Figure 5 As shown, it also includes a cooling box 18, which is used to cool and solidify the cut plastic granules;

[0055] The heating assembly includes a guide plate 19 inclinedly installed on the top wall of the cooling tank 18. A guide groove is provided on the guide plate 19, and a water cavity 20 is provided on the surface of the guide groove. A heat-conducting plate 21 covering the surface of the water cavity 20 is fixedly installed in the guide groove. A hot water pipe 22 with its top end communicating with the water tank 12 is inserted into the top wall of the water cavity 20.

[0056] By adopting the above technical solution, the high-temperature plastic particles that are cut during the working process first fall onto the surface of the guide plate 19, and then move downward along the inclined guide plate 19. During the movement of the plastic particles, the heat of the plastic particles is transferred to the water in the water chamber 20 through the heat conduction plate 21. At this time, the water temperature rises. Since the water with a higher temperature will automatically flow upward, the hot water in the water chamber 20 will flow along the hot water pipe 22 to the water tank 12, thereby providing hot water to the water tank 12 and simultaneously cooling the plastic particles.

[0057] like Figure 3 As shown, a guide rod is installed on the surface of the cutting blade 5, and a scraper 23 is slidably installed on the guide rod. An elastic rope 24 is installed between the scraper 23 and the mounting plate 4, and the elastic rope 24 is used to drive the scraper 23 to move.

[0058] By adopting the above technical solution, during the working process, the mounting plate 4 drives the cutting blade 5 to rotate rapidly. At this time, under the action of centrifugal force, the scraper 23 moves along the guide rod to the end away from the mounting plate 4, and the elastic rope 24 is in a stretched state. When the work is completed and the cutting blade 5 stops rotating, the elastic rope 24 pulls the scraper 23 to reset. During this process, the scraper 23 scrapes the surface of the cutting blade 5, thereby cleaning away the soft plastic residue on the surface of the cutting blade 5 in a timely manner, which plays a role in ensuring that the cutting blade 5 can be kept clean.

[0059] like Figure 6 As shown, a groove 26 is provided on the side wall of the scraper 23 near the cutting blade 5, and a pressure chamber 25 is provided on the elastic rope 24. A hole is provided on the side wall of the groove 26, and the hole communicates with the pressure chamber 25.

[0060] By adopting the above technical solution, during the restoration process of the elastic rope 24 made of rubber, the gas in the pressurized chamber 25 passes through the hole and enters the groove 26. At this time, the groove 26 is under high pressure and the gas in the groove 26 is discharged through the gap between the scraper 23 and the cutting blade 5. This can prevent solid substances from entering the gap between the cutting blade 5 and the scraper 23 and jamming the scraper 23, thus ensuring that the scraper 23 can be reset normally.

[0061] like Figure 5 As shown, a through groove 27 is horizontally opened on the surface of the heat-conducting plate 21, and an elastic membrane 28 is fixedly installed in the through groove 27. The elastic membrane 28 is used to reduce the impact force on the plastic particles.

[0062] A drain valve 29 is provided on the hot water pipe 22, and an inlet pipe 30 extending into the water tank 12 is inserted into the side wall of the water cavity 20. An inlet valve 31 is provided on the inlet pipe 30.

[0063] By adopting the above technical solution, since the elastic membrane 28 can deform, when the plastic particles cut by the cutting blade 5 fall onto the surface of the elastic membrane 28, the elastic membrane 28 will absorb the impact force of the particles, thus preventing the particles from deforming and becoming unqualified. At the same time, during the process of the elastic membrane 28 being impacted and deformed, the elastic membrane 28 can cause the water in the water cavity 20 to slosh around, while increasing the pressure in the water cavity 20. At this time, the hot water in the water cavity 20 is pressurized and passes through the hot water pipe 22 and the drain valve 29 into the water tank 12, which can accelerate the hot water transfer effect and improve the heat utilization rate. Meanwhile, during the cutting gap, no particles impact the elastic membrane 28, and the elastic membrane 28 recovers. Therefore, the water cavity 20 draws water through the water inlet pipe 30 and the water inlet valve 31, which can ensure that the water cavity 20 can continuously and quickly provide hot water to the water tank 12.

[0064] Instructions for use: During the processing, the raw material is heated and melted by the extruder 1, and then the strip-shaped plastic with a high temperature is extruded through the small hole on the mold 2. The motor 3 drives the mounting plate 4 and the cutting blade 5 to rotate quickly, which can cut the strip-shaped plastic into granules. By fixing the cutting blade 5 to the stabilizing sleeve 6, the drain hole 8 can always be aligned with the cutting blade 5, which can achieve the function of precisely cleaning the cutting blade 5.

[0065] After cutting, the cutting blade 5 continues to rotate. When the cutting blade 5 moves away from the mold 2, water can drain through the drain hole 8 onto the surface of the cutting blade 5 under the action of the water supply component. With the cooperation of the control component, the impact force of the water discharged from the drain hole 8 can be increased, thereby cleaning the plastic adhering to the surface of the cutting blade 5. Under the action of the heating component, the water discharged from the drain hole 8 is hot water, which prevents the plastic adhering to the surface of the cutting blade 5 from cooling and solidifying and fixing itself to the surface of the cutting blade 5. Therefore, the cutting blade 5 can be cleaned, reducing the number of downtime maintenance and improving work efficiency. Furthermore, the opening and closing of the control valve 11 can control whether the iron sand 10 in the material box 9 is mixed into the water in the cavity 7. When the valve 11 is open, the iron sand 10 flows with the water flow. Therefore, when the water flow impacts the surface of the cutting blade 5, the friction between the iron sand 10 and the cutting blade 5 can polish the cutting blade 5, ensuring that the cutting blade 5 remains sharp.

[0066] Since the iron sand 10 can be attracted by a magnet, after processing, the iron sand 10 mixed in with the plastic particles can be separated from the plastic particles by the magnet, which facilitates operation; and by keeping the material box 9 in a sealed state, the water discharged from the water tank 12 can be prevented from entering the material box 9.

[0067] During the cutting process, a water pump is installed in the water tank 12. Activating the pump discharges water from the water tank 12 into the cavity 7 through the outlet of the water tank 12, thus providing moisture to the cavity 7. Furthermore, the sliding fit between the sealing ring 13 and the annular groove ensures the normal rotation of the stabilizing sleeve 6. When the cavity 7 drives the moving magnet 15 to rotate onto the surface of the mold 2 to cut plastic particles, the attraction between the fixed magnet 14 and the moving magnet 15 overcomes the elastic force of the elastic element 17. At this time, the moving magnet 15 drives the sealing gasket 16 to move to the surface of the drain hole 8. The drain hole 8 on the surface of the mold 2 is then blocked by the sealing gasket 16, reducing the number of drain holes 8 that can drain water. This increases the impact force of the water flowing out of the drain holes 8, improving the impact effect on the cutting blade 5.

[0068] Furthermore, by blocking the drainage holes 8 located on the surface of the mold 2, water can be prevented from spraying onto the surface of the plastic strip to be cut, ensuring that the plastic strip remains soft and reducing the wear of the cutting blade 5.

[0069] During operation, the high-temperature plastic granules cut first fall onto the surface of the guide plate 19 and then move downwards along the inclined guide plate 19. As the plastic granules move, their heat is transferred to the water in the water chamber 20 via the heat-conducting plate 21, causing the water temperature to rise. Since the hotter water automatically flows upwards, the hot water in the water chamber 20 flows along the hot water pipe 22 into the water tank 12, thus providing hot water to the tank and simultaneously cooling the plastic granules. During operation, the mounting plate 4 drives the cutting blade 5 to rotate rapidly. Under centrifugal force, the scraper 23 moves along the guide rod to the end away from the mounting plate 4, and the elastic rope 24 is stretched. When the work is completed and the cutting blade 5 stops rotating, the elastic rope 24 pulls the scraper 23 back to its original position. During this process, the scraper 23 scrapes against the surface of the cutting blade 5, thus removing any residue. The soft plastic residue left on the surface of the cutting blade 5 is promptly removed. Because the elastic membrane 28 can deform, when plastic particles cut by the cutting blade 5 fall onto the surface of the elastic membrane 28, the elastic membrane 28 absorbs the impact force of the particles, preventing the particles from deforming and becoming defective. At the same time, during the process of the elastic membrane 28 deforming due to impact, the elastic membrane 28 can cause the water in the water chamber 20 to slosh around, increasing the pressure in the water chamber 20. At this time, the hot water in the water chamber 20 is pressurized and passes through the hot water pipe 22 and the drain valve 29 into the water tank 12, which accelerates the hot water transfer effect and improves the heat utilization rate. Meanwhile, during the cutting gap, no particles impact the elastic membrane 28, and the elastic membrane 28 recovers. Therefore, the water chamber 20 draws water through the water inlet pipe 30 and the water inlet valve 31, ensuring that the water chamber 20 can continuously and quickly provide hot water to the water tank 12.
