Description

Technical Field

[0001] This utility model relates to the field of recycled plastic processing, specifically a recycled plastic cutting and mixing device. Background Technology

[0002] Plastic recycled pellets are made from waste plastics. They are produced using discarded plastic products as raw materials and have a broad market. Wherever there are people in the world, waste plastics are inevitably generated. Moreover, the cost of processing them into recycled pellets is low, and the returns are quick. This provides a unique advantage for enterprises to set up waste plastic processing plants locally, turning waste into treasure. The raw materials are abundant and inexhaustible. Since plastic recycling requires the previous plastics to be cut and crushed, cutting and mixing equipment is required.

[0003] Existing recycled plastic cutting and mixing devices use rotating and fixed blades to cut materials. If the cut material falls directly through the feed inlet, it will concentrate in the center of the screen. Then, the screen is vibrated by a vibration mechanism so that the screen can screen the material. The intercepted material will slide off the screen through the vibration and be discharged through the outlet, preventing the intercepted material from accumulating on the screen. However, when a large amount of material falls into the center of the screen at the same time, it is not evenly distributed, resulting in poor screening effect of the screen on the accumulated material. Some material may be discharged through the outlet without being screened, thus reducing the screening efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a recycled plastic cutting and mixing device to solve the technical problem that the material is concentrated in the central area of ​​the screen, resulting in poor screening efficiency of the screen.

[0015] Furthermore, a cover plate is bolted to the top of the cutting cylinder, and a feed hopper is mounted on the top of the cover plate.

[0016] By adopting the above technical solution, it is convenient to add materials into the cutting cylinder through the feeding hopper, which facilitates the cutting of materials.

[0017] Furthermore, the guide seat is located directly above the screen, the guide port is circular, one side of the distribution plate is in contact with the inner wall of the guide port, and the top of the guide seat is inclined towards the guide port.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model is equipped with a guide seat, a guide port, a movable shaft, a distribution plate, a chain, and a sprocket. When the cut material falls onto the guide seat, it slides into the guide port. The second motor drives the drive shaft to rotate, which in turn drives the sprocket connected to it. The chain then drives the sprocket to rotate, which in turn drives the movable shaft to rotate. This, in turn, drives the distribution plate to rotate. The distribution plate disperses the material in the guide port layer by layer and distributes the material evenly to the highest point of the screen by rotating the blades (e.g., clockwise). This allows the material to slide downwards from the highest point of the screen for screening, extending the screening path. At the same time, the rotation of the guide plate provides a downward pushing force for the material. Combined with the up-and-down vibration of the screen, this design prevents the material from stagnating in the guide port and allows the dispersed material to slide quickly on the screen and be screened by vibration, thereby improving the screening efficiency.

[0027] 2. The guide seat of this utility model is set with an inclined surface, which makes it easy for the material falling to the top of the guide seat to slide into the inside of the guide port along the inclined surface, reducing the amount of material accumulating on the top of the guide seat. At the same time, one side of the distribution plate is in contact with the inner wall of the guide port, and when rotating, it can scrape off the material attached to the inner wall in real time, preventing the material from adhering to the inner wall of the guide port.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] Example 1:

[0041] A recycled plastic cutting and mixing device, such as Figures 1-9 As shown, the device includes a main body 1. An inclined platform 13 is fixed to one side of the main body 1. A housing 14 is installed at the bottom of the inclined platform 13. Multiple springs 15 are installed on the upper part of the housing 14. The springs 15 are made of 50CrVA / 65Mn spring steel. A movable plate 16, extending through to the bottom of the housing 14, is connected to the bottom of the springs 15. A screen 17 is installed at the bottom of the movable plate 16. Multiple telescopic rods 21 are installed on the other side of the main body 1, and the top ends of the telescopic rods 21 are fixedly connected to the bottom of the screen 17. A second motor 19 is installed on the outer surface of the main body 1 of the device, and the output end of the second motor 19 is connected to a drive shaft 12 extending into the interior of the main body 1 of the device. Two cams 20 are installed on the outer wall of the drive shaft 12. When the screen 17 moves upward, it can push the movable plate 16 upward. The movable plate 16 squeezes the spring 15, so that the spring 15 is compressed, which facilitates the subsequent pushing of the movable plate 16 downward to reset. A door 26 is installed on the outer surface of the main body 1 of the device via a hinge. An observation window made of polycarbonate material is installed on the outer surface of the door 26.

[0042] See Figures 1-6The main body 1 of the device has a guide seat 31 inside, and a guide port 32 is opened on one side of the guide seat 31. A movable shaft 33 is connected to the inside of the guide port 32 through a sealed bearing. Multiple material distribution plates 34 are installed on the outer wall of the movable shaft 33. A sprocket 30 is installed at one end of the movable shaft 33 extending to the outside of the main body 1 and at one end of the drive shaft 12 extending to the outside of the main body 1. A chain 35 is sleeved between two sprockets 30. The guide seat 31 is located directly above the screen 17. The guide port 32 is circular. One side of the material distribution plate 34 is attached to the inner wall of the guide port 32, so that the material being cut... The material can enter the feed inlet 32 ​​and rotate with the distribution plate 34. The cam 20 is located below the screen 17. One side of the screen 17 is inclined downward along the direction of the discharge port 22. When the cam 20 rotates, it can push the screen 17 upward. When the cam 20 continues to rotate and does not contact the screen 17, the screen 17 moves downward. This repetition can make the screen 17 vibrate. The driving gear 8 meshes with the driven gear 10. The diameter of the driving gear 8 is smaller than the diameter of the driven gear 10. When the driving gear 8 rotates, it will drive the driven gear 10 to rotate. The rotation of the driven gear 10 will drive the rotating shaft 9 to rotate.

[0043] See Figures 1-7 A third motor 23 is installed on one side of the device body 1, and the output end of the third motor 23 is connected to a stirring rack 24 extending into the device body 1. When it is necessary to stir the cut material, the third motor 23 can be started. The operation of the third motor 23 can drive the stirring rack 24 to rotate so as to stir the cut material. A cutting cylinder 27 is installed on the top of the device body 1. Multiple fixed blades 4 are fixed inside the cutting cylinder 27. A frame 6 is fixed inside the cutting cylinder 27. A guide platform 5 is installed on the top of the frame 6 so that the material can enter into the cutting cylinder 27 and be cut. A feeding pipe 29 is connected to the other side of the top of the device body 1. A discharge valve 18 is connected to the middle of the bottom of the device body 1. A sealing plate 28 is installed on the outer surface of the cutting cylinder 27 by bolts.

[0044] See Figures 1-8A first motor 7 is installed inside the lower part of the frame 6, and the output end of the first motor 7 is connected to a drive gear 8. A rotating shaft 9 is also connected inside the frame 6 via bearings, and the top of the rotating shaft 9 passes through the guide table 5. A driven gear 10 is installed on the lower part of the outer wall of the rotating shaft 9. Through holes are provided on both sides of the frame 6, and dustproof meshes are installed inside the through holes. When the cutting blade 11 needs to rotate, the first motor 7 can be started. The operation of the first motor 7 drives the drive gear 8 to rotate, which in turn drives the driven gear 10 to rotate. Multiple cutting blades 11 are installed on the upper part of the outer wall of the rotating shaft 9, and the cutting blades 11 intersect with the fixed blade 4. In the incorrect configuration, when the rotating shaft 9 rotates, it can drive the cutting blade 11 to rotate. The cutting blade 11, together with the fixed blade 4, can cut the incoming material. The top of the cutting cylinder 27 is bolted with a cover plate 2, and the top of the cover plate 2 is equipped with a feed hopper 3, which facilitates the feeding of material into the cutting cylinder 27 for easy cutting. The outer surface of the main body 1 is also equipped with a control panel 36, which is electrically connected to the first motor 7, the second motor 19 and the third motor 23 respectively, so as to facilitate the start or stop of the first motor 7, the second motor 19 and the third motor 23 through the control panel 36.

[0045] Example 2:

[0046] Based on the above embodiment 1, in order to facilitate the collection of material intercepted at the top of the screen 17, the following structure will be set.

[0047] Specifically, a discharge port 22 is provided on one side of the main body 1 of the device, and a collection box 25 is placed on the top side of the main body 1 of the device. The collection box 25 can collect materials that have not passed through the screen 17, so that the staff can pour the materials into the feed hopper 3 for further cutting.

[0048] Example 3:

[0049] Based on the above embodiment 1, the following design will be adopted to facilitate the material to slide from the top of the guide seat 31 into the inside of the guide port 32.

[0050] Specifically, the top of the guide seat 31 is set at an angle and tilted towards the guide port 32, so that the material falling to the top of the guide seat 31 will slide along the angle into the guide port 32, reducing the amount of material accumulating on the top of the guide seat 31.

[0051] The working principle of this utility model is as follows: First, before use, the operator can connect the power supply and start the first motor 7 and the second motor 19. Then, the material is added into the cutting cylinder 27 through the feed hopper 3. The output end of the first motor 7 drives the drive gear 8 to rotate. The drive gear 8 meshes with the driven gear 10, and the torque is increased through gear reduction to adapt to the cutting of thick and hard materials. The driven gear 10 drives the rotating shaft 9 to rotate. The cutting blade 11 on the outer wall of the rotating shaft 9 rotates synchronously with the rotating shaft, forming an "interlaced shearing" with the fixed blade 4 in the cutting cylinder 27 to cut the material.

[0052] After cutting, the material first enters the guide port 32 of the guide seat 31. The second motor 19 drives the drive shaft 12 to rotate, which in turn drives the sprocket 30 connected to it to rotate. Then, the chain 35 drives another sprocket 30 to rotate, which in turn drives the movable shaft 33 to rotate. The material distribution plate 34 on the outer wall of the movable shaft 33 rotates with the shaft, dispersing the material evenly to the high point area of ​​the screen 17 to avoid concentrated impact. The output end of the second motor 19 drives the drive shaft 12 to rotate, and the two cams 20 on the outer wall of the drive shaft 12 rotate synchronously. When the cams 20 rotate, they periodically push the bottom of the screen 17. When the screen moves up, they push the movable plate 16 to squeeze the spring 15. When the cams 20 continue to rotate until they no longer contact the screen 17, the spring 15 releases its elastic force, pushing the movable plate 16 and the screen 17 to move down and reset, forming an up-and-down reciprocating vibration so that the screen 17 can screen the material. At the same time, the material intercepted by the screen 17 can slide towards the discharge port 22.

[0053] Start the third motor 23. The output of the third motor 23 drives the mixing rack 24 to rotate, and the screened material will fall down into the mixing area. At the same time, the staff can add additives (such as color masterbatch, antioxidants) through the feeding pipe 29. The mixing rack 24 will stir the material and additives to make the material and additives fully mixed. After the mixing is completed, open the discharge valve 18 to discharge the mixed material.

[0054] The material intercepted by the screen 17 will slide into the collection box 25 through the discharge port 22. The unqualified material collected by the collection box 25 can be periodically poured into the feed hopper 3 by the staff and re-entered into the cutting process for secondary cutting.
