Technical Field
[0001] This utility model relates to the field of pelletizing technology, specifically to a high-efficiency pelletizing device for the production of plastic pellets. Background Technology
[0002] Plastics are important organic synthetic polymer materials with a wide range of applications. Plastics are typically transported in granular form to ensure safe transport, and plastic pelletizing usually requires pelletizing equipment. Generally, plastic pelletizing involves mixing powdered raw materials using a twin-screw mixer, then stretching the plastic using a stretching machine, and finally cutting the plastic into pellets using a cutting device.
[0003] A Chinese patent (publication number CN217573626U) discloses a rubber and plastic pelletizer. The pelletizer has a housing with a feeding mechanism and a discharging mechanism inside. A motor is vertically connected to the pelletizer housing outside the feeding mechanism. The output shaft of the motor passes through the pelletizer housing and is connected to an active mechanism. A base is provided at the bottom of the pelletizer housing. By guiding and uniformly feeding the rubber and plastic, the cutting blades cut the rubber and plastic, and the plastic pellets flow out from the discharge hopper, which facilitates the discharge of the pelletizer.
[0004] However, in actual use, the rubber and plastic pelletizer designed above results in the pellets falling into the hopper through the feeding notch. The hopper is installed inside the pelletizer housing and has a limited diameter. When a large number of rubber and plastic pellets flow from the hopper, the feeding speed is slow, which may cause blockage and affect the feeding speed of the pelletized rubber and plastic pellets, resulting in an unsmooth feeding process and a low feeding rate.

[0020] 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 protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution: including a pelletizing box 1 and a feed inlet 4 opened on one side of the top of the pelletizing box 1. A feed hopper 13 is fixedly installed inside the pelletizing box 1. A drive motor 15 is fixedly installed on the outer side of the feed hopper 13. A half gear 20 is fixedly installed on the drive end of the drive motor 15. A slider 19 is slidably connected to the outer side of the feed hopper 13. A sliding groove 16 is opened on one side of the feed hopper 13. A rack 21 is fixedly connected to the inner side of the slider 19. The rack 21 is meshed with the half gear 20. A moving plate 14 is slidably arranged inside the feed hopper 13. A lever 22 is fixedly connected to the bottom of the moving plate 14. One end of the moving plate 14 is fixedly connected to the slider 19. A connecting post 17 is fixedly connected to one end of the moving plate 14. The connecting post 17 is slidably connected to the sliding groove 16. A connecting block 18 is fixedly connected to the end of the connecting post 17 away from the sliding groove 16. The connecting block 18 is fixedly installed on the outer side of the slider 19.
[0022] It should be noted that there are multiple levers 22, which are evenly spaced at the bottom of the moving plate 14. There are two racks 21, which are fixedly installed on both sides of the inside of the slide 19 and can mesh with the half gears 20 respectively. The half gears 20 are located in the middle of the slide 19.
[0023] In practice, the workers feed the plastic material to be processed into the feed port 4 on one side of the pelletizing box 1. The material is then conveyed between two guide rollers 2 to the bottom of the cylinder 3. The cylinder 3 drives the cutting blade 11 to move and cut the plastic material into pellets. The pellets slide down the inclined plate 10 and fall from the feed trough 12 into the feed hopper 13. The drive motor 15 is started to drive the half gear 20 to rotate. When the half gear 20 rotates, it meshes with the two racks 21 in sequence, causing the sliding part 19 to slide back and forth on one side of the feed hopper 13. When the sliding part 19 slides, it drives the moving plate 14 to move inside the feed hopper 13 through the connecting column 17. Multiple levers 22 slide along the tilt angle of the feed hopper 13 inside the feed hopper 13, which helps to improve the efficiency of the plastic pellets being fed into the feed hopper 13.
[0024] See Figure 1 and Figure 2 A rotating motor 6 is fixedly installed on the outside of the pelletizing box 1. A rotating rod 7 is fixedly connected to the drive end of the rotating motor 6. The rotating rod 7 is rotatably set on one side of the feeding hopper 13. A cam 8 is sleeved in the middle of the rotating rod 7. The cam 8 is in movable contact with the feeding hopper 13.
[0025] By setting cam 8, the external rotating motor 6 of pelletizing box 1 is started. The rotating motor 6 drives the rotating rod 7 to rotate. When the rotating rod 7 rotates, cam 8 rotates synchronously with the rotating rod 7. The protrusion of cam 8 contacts the feeding hopper 13 when rotating, causing the feeding hopper 13 to vibrate, thus preventing blockage when plastic pellets are fed from the feeding trough 12.
[0026] See Figure 2 A cylinder 3 is fixedly installed on one side of the top of the pelletizing box 1. A cutting blade 11 is fixedly connected to the telescopic end of the cylinder 3. An inclined plate 10 is fixedly installed below the cutting blade 11. A feeding trough 12 is opened on one side of the inclined plate 10. A feeding hopper 13 is set at the bottom of the feeding trough 12.
[0027] By setting cylinder 3, the plastic material to be processed is fed into the feed port 4 on one side of the pelletizing box 1, and is conveyed between two guide rollers 2 to the bottom of cylinder 3. Cylinder 3 drives the cutting blade 11 to move and cut the plastic material into pellets. The pellets slide down the inclined plate 10 and fall from the feed trough 12 into the feed hopper 13.
[0028] See Figure 2 The pelletizing box 1 is equipped with a rotating guide roller 2. There are two guide rollers 2, and both guide rollers 2 are located on the side of the inclined plate 10 away from the feeding trough 12.
[0029] By setting two rotatable guide rollers 2, the plastic material to be processed is stretched from the previous process and then transferred from the two rotatable guide rollers 2 to the cutting blade 11 for pelletizing. The guide rollers 2 guide the plastic material being transported, making it easier for it to be transported.
[0030] See Figure 1 The pelletizing box 1 has a discharge port 5 fixedly connected to one side of the outside, and the discharge port 5 is connected to the feeding hopper 13.
[0031] By setting a discharge port 5 connected to the hopper 13, the plastic pellets can flow out from the discharge port 5, making it easy for workers to collect them.
[0032] See Figure 2 and Figure 4 A mounting component 9 is fixedly installed on one side of the sliding component 19. The mounting component 9 is fixedly installed on one side of the hopper 13, and the drive motor 15 is fixedly installed on the top of one side of the mounting component 9.
[0033] By setting the mounting part 9, the shape of the mounting part 9 is set to "L" shape, which facilitates the installation of the drive motor 15.
[0034] See Figure 3 The slide 19 is connected to a guide slider on the side near the hopper 13, and a guide groove is provided on the side of the hopper 13 near the slide 19. The guide slider is slidably connected to the guide groove.
[0035] By providing a guide slider on the side of the slide 19 near the hopper 13, the slide 19 can slide on one side of the hopper 13 via the guide slider, which helps to improve the stability of the slide 19.
[0036] Working principle: When using the device, the operator feeds the plastic material to be processed into the feed port 4 on one side of the pelletizing box 1. The material is conveyed between two guide rollers 2 to the area below the cylinder 3. The cylinder 3 drives the cutting blade 11 to move, cutting the plastic material into pellets. The pellets slide down the inclined plate 10 and fall from the discharge chute 12 into the discharge hopper 13. The external rotating motor 6 of the pelletizing box 1 is then started. The rotating motor 6 drives the rotating rod 7 to rotate. When the rotating rod 7 rotates, the cam 8 rotates synchronously with it. The protrusion of the cam 8 interacts with the discharge hopper during rotation. Contact 13 causes the hopper 13 to vibrate, preventing blockage when plastic granules are discharged from the discharge trough 12; start the drive motor 15 to drive the half gear 20 to rotate. When the half gear 20 rotates, it meshes with the two racks 21 in sequence, causing the slider 19 to slide back and forth on one side of the hopper 13. When the slider 19 slides, it drives the moving plate 14 to move inside the hopper 13 through the connecting column 17. Multiple levers 22 slide along the tilt angle of the hopper 13 inside the hopper 13, which facilitates the improvement of the efficiency of plastic granules being discharged from the hopper 13.
