Description

Technical Field

[0001] This utility model relates to the technical field of plastic pelleting equipment, specifically to a plastic pelleting collection device. Background Technology

[0002] Typically, plastic granulation involves mixing powdered raw materials using a twin-screw mixer, then stretching the plastic using a stretching machine, cutting the plastic into granules using a cutting device, and finally having the granules blown into a collection cylinder by a blower for easy collection and transportation by workers.

[0003] A Chinese patent (publication number CN208215754U) discloses a plastic pelleting and collecting device. Plastic pellets are fed into a collecting cylinder by a blower from a feeding channel. Inside the collecting cylinder, hollow baffles can block the plastic pellets blown by the blower, reducing the occurrence of plastic pellets scattering from the air outlet. The plastic pellets then fall onto a screen inside the frame. A vibrating motor vibrates the screen, and the plastic pellets on the screen fall out of the vibrating separation mechanism through outlet one, while the plastic pellets below the screen fall out of the collecting device through outlet two.

[0004] However, in actual use, the plastic pelleting and collecting device designed above uses frame vibration to screen plastic pellets of the required size. The fixed screen collecting device can only collect pellets of a specific size. When the size of the granulated plastic pellets changes, the fixed screen collecting device has certain limitations, reducing the versatility of the equipment. To adapt to different sizes of plastic pellets, different screening and collecting devices need to be replaced, which increases the production cost of plastic pelleting and collecting.

[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: it includes a base 1, a screening platform 4 is provided on the top of the base 1, a screening groove 14 is provided on the top of the screening platform 4, a screening groove 22 is provided inside the screening platform 4, a snap-fit ​​groove 21 is provided at the bottom of the screening groove 14, the snap-fit ​​groove 21 communicates with the screening groove 22, a screen frame 19 is snapped in the snap-fit ​​groove 21, a screen 20 is fixedly installed inside the screen frame 19, an installation groove 9 is provided on the side of the screening groove 14 near the snap-fit ​​groove 21, a slider 10 is slidably provided in the installation groove 9, a round rod 11 is fixedly connected to one side of the slider 10, one end of the round rod 11 is inserted into the inside of the screen frame 19, a return spring 12 is sleeved on the outside of the round rod 11, one end of the return spring 12 is fixedly connected to the slider 10, and the other end of the return spring 12 is fixedly connected to the inner wall of the installation groove 9.

[0022] It should be noted that there are multiple mounting slots 9, which are respectively located at the four corners of the snap-fit ​​slot 21, and can fix the screen frame 19.

[0023] In practice, when it is necessary to use the screening table 4 to screen and collect plastic particles of different sizes, this can be achieved by replacing the screen 20. After sliding the slide plate 7 into the slot 8, move the slider 10 to move it away from the screen frame 19. The return spring 12 is stretched, and the round rod 11 slides with the slider 10 until the round rod 11 moves away from the screen frame 19, releasing the restriction on the screen frame 19. The operator can then remove the screen frame 19 and the screen 20 from the snap-fit ​​slot 21, making it easy to replace the screen 20 with different mesh sizes.

[0024] See Figure 3 A rotating motor 16 is fixedly installed on one side of the screening table 4. A screw 18 is fixedly connected to the drive end of the rotating motor 16. A support plate is fixedly installed on one side of the top of the screening table 4. One end of the screw 18 is rotatably connected to the support plate. A brush plate 17 is threaded into the outer side of the screw 18. Brush bristles are fixedly connected to the bottom of the brush plate 17.

[0025] By setting the support plate on one side of the mounting groove 9, the sliding of the slide plate 7 and the removal of the screen frame 19 in the mounting groove 9 are not affected. After screening the plastic particles, the rotating motor 16 can be started to rotate the screw 18, so that the brush plate 17 slides in the screening groove 14. The initial position of the brush plate 17 is located on one side of the screen frame 19. The brush plate 17 slides from one end of the screen frame 19 to the end close to the first collection hopper 6. The brush plate 17 drives the bristles to clean the screen 20, so as to avoid the residue on the screen 20 clogging the screen 20 and affecting the screening efficiency of the screen 20.

[0026] See Figure 3 A hole is provided on one side of the brush plate 17, and a guide rod is inserted into the hole. One end of the guide rod is fixedly connected to the inner wall of the screening tank 14, and the other end of the guide rod is fixedly connected to the support plate.

[0027] By setting guide rods, the stability of the brush plate 17 moving on the top of the screening table 4 is improved. Both the guide rods and the screw 18 are set above one side of the screen frame 19 and do not contact the screen frame 19.

[0028] See Figure 1 A vibration motor 5 is fixedly installed at the bottom of the screening table 4, and a vertical rod 2 is fixedly installed at the top of the base 1. A telescopic spring 3 is fixedly connected to the top of the vertical rod 2, and the other end of the telescopic spring 3 is fixedly connected to the bottom of the screening table 4.

[0029] By setting up a vibration motor 5, when the device is in use, the operator throws the plastic granules to be screened and collected from the top side of the screening table 4, which is away from the first collection hopper 6, and starts the vibration motor 5. The vibration motor 5 causes the screening table 4 to vibrate on the top of the base 1. The screening table 4 can vibrate on the top of the upright 2 through the telescopic spring 3.

[0030] See Figure 1 One end of the screening platform 4 is fixedly connected to the first collection hopper 6, the screening trough 14 is connected to the first collection hopper 6, one end of the screening platform 4 is fixedly connected to the second collection hopper 15, one end of the screening platform 4 is provided with a rectangular groove, the rectangular groove is connected to the second collection hopper 15, a first collection bucket is provided below the first collection hopper 6, and a second collection bucket is provided below the second collection hopper 15.

[0031] Workers drop the plastic granules to be screened and collected from the top side of the screening platform 4, away from the first collection hopper 6, and start the vibration motor 5. The vibration motor 5 causes the screening platform 4 to vibrate on the top of the base 1. The plastic granules flow from the screening trough 14 to the first collection hopper 6 through vibration and are collected in the first collection bucket, or are screened from the screening trough 14 to the screening trough 22 and flow out from the second collection hopper 15 to the second collection bucket for collection. After the plastic granules are screened through the screens 20 with different apertures, plastic granules of different sizes can flow through the first collection hopper 6 and the second collection hopper 15 respectively into the first collection bucket and the second collection bucket, thus completing the screening and collection of plastic granules.

[0032] See Figure 2 A slot 8 is provided on the top of one side of the mounting slot 9. A slide plate 7 is slidably inserted into the slot 8. A limit plate is connected to one side of the slide plate 7 and is slidably disposed inside the slot 8.

[0033] By setting up the slide plate 7, before screening, one end of the slide plate 7 can be slid out from the slot 8 until it slides to one side of the inner wall of the mounting groove 9, preventing particles from flowing into the mounting groove 9. A limiting plate is also set at one end of the slide plate 7.

[0034] The limiting plate can only slide inside the slot 8 to prevent the slide plate 7 from dislodging from the slot 8.

[0035] See Figure 2 A guide post 13 is fixedly installed in the mounting groove 9, and a through hole is opened on the slider 10, which is movably inserted into the outside of the guide post 13.

[0036] By setting the guide post 13, the slider 10 can slide along the guide post 13, which facilitates the increase of the stability of the slider 10 sliding in the mounting groove 9.

[0037] Working principle: When using the device, the operator throws the plastic granules to be screened and collected from the top side of the screening platform 4, away from the first collection hopper 6. The vibrating motor 5 is then started, causing the screening platform 4 to vibrate on top of the base 1. The plastic granules flow from screening trough 14 to the first collection hopper 6 via vibration, and are collected in the first collection bucket. Alternatively, they are screened from screening trough 14 to screening trough 22 and flow out from the second collection hopper 15 to the second collection bucket for collection. When it is necessary to use the screening platform 4 to further process the granules... When collecting plastic granules of different sizes, the screen 20 can be replaced. After sliding the slide plate 7 into the slot 8, the slider 10 is moved away from the screen frame 19. The return spring 12 is stretched, and the round rod 11 slides with the slider 10 until the round rod 11 moves away from the screen frame 19, releasing the limit on the screen frame 19. The operator can then remove the screen frame 19 and the screen 20 from the snap-fit ​​slot 21, making it easy to replace the screen 20 with a different mesh size.

[0038] After screening the plastic granules, the rotating motor 16 can be started to rotate the screw 18, causing the brush plate 17 to slide in the screening trough 14. The initial position of the brush plate 17 is located on one side of the screen frame 19. The brush plate 17 slides from one end of the screen frame 19 to the end close to the first collection hopper 6. The brush plate 17 drives the bristles to clean the screen 20, preventing debris from remaining on the screen 20 and clogging the screen 20, thus affecting the screening efficiency of the screen 20.
