Description

Technical Field

[0001] This utility model relates to the field of plastic pellet processing technology, and in particular to a waste screening device for plastic pellet processing. Background Technology

[0002] Waste screening devices in plastic pellet processing are crucial equipment for ensuring product quality and recycling rates. These devices utilize different technologies and principles to effectively classify and process waste materials. A waste screening device for plastic pellet processing is specifically designed to handle waste generated during the plastic pellet processing process, screening and classifying it according to different specifications, materials, or qualities. The working principle of the screening device is mainly based on the physical properties of the material, such as particle size, density, and shape, using different screens or sieve plates to grade the waste.

[0003] Existing waste recycling equipment used in plastic pellet production suffers from poor recycling efficiency, inability to perform automatic internal cleaning, reduced equipment efficiency and effectiveness, and inability to perform necessary secondary processing and mixing of fine particles.

[0004] An existing patent (publication number: CN216775900U) discloses a pesticide spraying device for rice cultivation, which includes a support and fixing plate, a mixing box, and a separation box. An adjusting rod is installed inside the separation box, and a rotating rod is connected to the inner wall of the separation box. A spray head is installed at the end of the rotating rod, and a water pipe is connected to the outside of the spray head. A screening device is installed inside the separation box, and a drive motor is connected to the outside of the mixing box. A rotating rod is installed on the output shaft of the drive motor. The device uses the adjusting rod to drive the rotating rod to adjust its angle as needed, allowing for corresponding angle adjustments of the spray head according to usage requirements. This achieves automatic cleaning of the separation box's interior, ensuring cleanliness and meeting the needs of processing and screening. Its primary and secondary screening plates work together to separate plastic particles according to different requirements, ultimately achieving optimal processing efficiency.

[0005] To address the aforementioned issues, existing patents offer solutions that utilize a combination of primary and secondary screening plates to separate plastic particles to meet different requirements and achieve optimal processing efficiency. However, during use, the screens are fixed, and a large quantity of particles needs to be poured in for screening, making the screens prone to clogging. Summary of the Invention

[0006] The purpose of this invention is to provide a waste screening device for plastic granule processing. The first filter cylinder filters smaller plastic granules, while the second filter cylinder filters larger granules. Since the first and second filter cylinders can rotate, the plastic granules inside are stirred, thereby effectively reducing the clogging of the granules and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a waste screening device for plastic granule processing, comprising a device shell, wherein a screening mechanism for screening waste is provided inside the device shell, and an adjustment mechanism for adjusting the device angle is provided on the lower surface of the device shell;

[0008] The screening mechanism includes a first filter cylinder, which is installed inside the device housing. A second filter cylinder is fixed to one end of the first filter cylinder. Four fixing rods are fixed inside both the first and second filter cylinders. A transmission rod is fixed to the end of each of the four fixing rods. A drive motor that is bolted to the device housing is fixed to the input end of the transmission rod.

[0009] Preferably, a fixed bearing is fitted at the end of the transmission rod, and a fixing block that is fixedly connected to the outer shell of the device is fixed on the outer surface of the fixed bearing.

[0010] Preferably, the lower end of the device housing is provided with a first collection box corresponding to the first filter cartridge, and the right side of the first collection box is provided with a second collection box corresponding to the second filter cartridge.

[0011] Preferably, a partition plate is fixed to the inner wall of the device housing.

[0012] Preferably, the right side of the device housing has an outlet that communicates with the second filter cartridge.

[0013] Preferably, the adjustment mechanism includes four support legs, all of which are hinged to the lower surface of the device housing, and the lower ends of two of the support legs are telescopically connected to adjustment components.

[0014] Preferably, the lower end of the adjusting component is fixed with an adjusting electric cylinder by screws, and the telescopic end of the adjusting electric cylinder is fixed with a limiting block that is fixedly connected to the supporting leg.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the screening mechanism, the first filter cylinder filters smaller particles in the plastic granules, while the second filter cylinder filters larger particles. Since the first and second filter cylinders can rotate, the plastic granules inside are stirred, thereby effectively reducing the clogging of the granules.

[0017] 2. Through the adjustment mechanism, the adjustment cylinder inside the adjustment component can drive the limit block to move, so that the horizontal angle of the device shell changes, the feed inlet of the first filter cylinder is at a high position, and the discharge outlet of the second filter cylinder is at a low position.

Detailed Implementation

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A waste screening device for plastic pellet processing includes a device housing 1, a screening mechanism for screening waste is provided inside the device housing 1, and an adjustment mechanism for adjusting the device angle is provided on the lower surface of the device housing 1.

[0028] The screening mechanism includes a first filter cylinder 2, which is installed inside the device housing 1. A second filter cylinder 21 is fixed to one end of the first filter cylinder 2. Four fixing rods 22 are fixed inside both the first filter cylinder 2 and the second filter cylinder 21. A transmission rod 23 is fixed to the end of each of the four fixing rods 22. A drive motor 24 bolted to the device housing 1 is fixed to the input end of the transmission rod 23. A fixed bearing 25 is sleeved on the end of the transmission rod 23. A fixing block 26 fixedly connected to the device housing 1 is fixed to the outer surface of the fixed bearing 25. A first collection box 3 corresponding to the first filter cylinder 2 is provided at the lower end of the device housing 1. A second collection box 4 corresponding to the second filter cylinder 21 is provided on the right side of the first collection box 3. A partition plate 5 is fixed to the inner wall of the device housing 1.

[0029] By adopting the above technical solution, before using the waste screening device for plastic granule processing, the outer shell 1 of the device is first placed in a suitable position. When in use, the plastic granules to be screened are poured in through the feed port of the first filter cylinder 2. At the same time, the drive motor 24 is started, driving the transmission rod 23 to rotate. With the cooperation of the fixed rod 22, the first filter cylinder 2 and the second filter cylinder 21 can rotate. The plastic granules are filtered in the first filter cylinder 2 and the second filter cylinder 21. The aperture of the first filter cylinder 2 is smaller than that of the second filter cylinder 21, so that the first filter cylinder 2 filters the smaller particles in the plastic granules, while the second filter cylinder 21 filters the larger particles. Since the first filter cylinder 2 and the second filter cylinder 21 can rotate, the plastic granules inside are stirred, thereby effectively reducing the clogging of particles. The fixed bearing 25 set on the fixed block 26 can ensure the stability of the transmission rod 23 when rotating.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the right side of the device housing 1 has an outlet 6 that communicates with the second filter cartridge 21. The adjustment mechanism includes support legs 7, and there are four support legs 7. All four support legs 7 are hinged to the lower surface of the device housing 1. The lower ends of two of the support legs 7 are telescopically connected to adjustment components 71. The lower end of the adjustment component 71 is fixed with an adjustment cylinder 72 by screws. The telescopic end of the adjustment cylinder 72 is fixed with a limiting block 73 that is fixedly connected to the support leg 7.

[0031] By adopting the above technical solution, the stability of the device is ensured by the supporting leg 7, and the adjusting electric cylinder 72 in the adjusting component 71 can drive the limiting block 73 to move, so that the horizontal angle of the device shell 1 changes. The feed inlet of the first filter cylinder 2 is at a high position, while the discharge outlet of the second filter cylinder 21 is at a low position. After filtration, smaller particles fall into the first collection box 3, and larger particles fall into the second collection box 4 for collection. The partition plate 5 in the device shell 1 can separate the first filter cylinder 2 and the second filter cylinder 21, while the plastic particles that meet the requirements are discharged to the outside for collection through the discharge port 6.

[0032] Working principle: Adjusting the electric cylinder 72 drives the limit block 73 to move, changing the horizontal angle of the device housing 1. The inlet of the first filter cylinder 2 is at a higher position, while the outlet of the second filter cylinder 21 is at a lower position. The plastic granules to be screened are poured in through the inlet of the first filter cylinder 2. At the same time, the drive motor 24 drives the transmission rod 23 to rotate. With the cooperation of the fixed rod 22, the first filter cylinder 2 and the second filter cylinder 21 can rotate. The plastic granules are filtered in the first filter cylinder 2 and the second filter cylinder 21. The pore size of the first filter cylinder 2 is smaller than that of the second filter cylinder 21, so that the first filter cylinder 2... Smaller plastic particles are filtered out, while larger particles are filtered out by the second filter cylinder 21. Since the first and second filter cylinders 21 can rotate, the plastic particles inside are stirred. The fixed bearing 25 on the fixed block 26 ensures the stability of the transmission rod 23 during rotation. After filtration, smaller particles fall into the first collection box 3, and larger particles fall into the second collection box 4 for collection. The partition plate 5 inside the outer casing 1 can separate the first and second filter cylinders 21. Plastic particles that meet the requirements are discharged to the outside for collection through the discharge port 6.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
