Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sorting equipment, specifically relating to a multifunctional waste plastic sorting table. Background Technology
[0002] The recycling and processing of waste plastics is a systematic project that requires processes such as pretreatment, crushing, deep cleaning, dehydration, melt granulation, pelletizing, and packaging to process mixed plastic waste into pure plastic pellets for further processing and utilization. Pretreatment includes a pre-sorting process, the main purpose of which is to remove impurities (such as metal, wood, glass, and other non-plastic waste) and to roughly classify the waste according to material or color for subsequent recycling.
[0003] Currently, most waste plastic sorting relies on manual sorting and classification, which is inefficient and cannot simultaneously perform impurity removal and compression. Utility Model Content
[0004] To address the problems mentioned in the background, this utility model provides a multifunctional waste plastic sorting table that can simultaneously perform compression, impurity removal, and sorting, greatly improving sorting efficiency.
[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A multifunctional waste plastic sorting station includes a frame, on which a drive roller and a driven roller are rotatably connected. A conveyor belt obliquely positioned to the lower left is connected between the drive roller and the driven roller. A drive device is connected to one end of the drive roller. Mounting side plates are fixedly connected to both sides of the frame. Lower pressure rollers, evenly distributed and rolling in contact with the upper surface of the conveyor belt, are rotatably connected between the mounting side plates. The lower pressure rollers are close to each other but do not touch. An axially arranged groove is formed on the outer wall of the lower pressure roller. An upper pressure roller device is located above the right side of the conveyor belt. A color recognition component is located above the left end of the conveyor belt. A sorting plate is rotatably connected to the lower outer side of the conveyor belt. A servo motor is connected to one end of the sorting plate. The servo motor is electrically connected to the color recognition component. Multiple sets of support cylinders are arranged between the drive roller and the driven roller. Electromagnetic devices are installed inside the support cylinders.
[0006] As a further provision of the above scheme, the upper pressure roller device includes an upper mounting plate, on which a hydraulic cylinder device is fixedly connected, and the output end of the hydraulic cylinder device is fixedly connected to an upper pressure roller parallel to the lower pressure roller.
[0007] As a further feature of the above scheme, a feeding hopper is provided on the right side of the hydraulic cylinder device, a guide plate that is obliquely arranged to the lower left is fixedly connected to the right side of the lower end face of the upper mounting plate, and a vertically downward protective fence is fixedly connected to the left end of the lower end face of the upper mounting plate.
[0008] As a further feature of the above scheme, a feeding baffle is fixedly connected above the sorting plate and positioned diagonally to the lower left. A storage box is located directly below the sorting plate, and a partition is fixedly connected in the middle of the storage box.
[0009] As a further feature of the above scheme, a scraper is fixedly connected to the right side of the frame, and the scraper abuts against the right end of the conveyor belt.
[0010] This utility model has the following beneficial effects: The drive unit rotates the active roller, causing the conveyor belt to move clockwise relative to it, conveying the plastic upwards. Simultaneously, the conveyor belt drives the lower pressure rollers to rotate counterclockwise relative to it, feeding the plastic from the hopper onto the lower pressure rollers. The lower pressure rollers work together to convey the plastic downwards. During the downward conveying process, the plastic tumbles and bounces on the lower pressure rollers. At the same time, the hydraulic cylinder device drives the upper pressure roller to compress the plastic. Impurities on the plastic fall off and fall into the conveyor belt through the gaps between the lower pressure rollers. The impurities are automatically conveyed upwards. During the downward conveying process, the color recognition component identifies the plastic. When the plastic falls off the lower pressure rollers, the servo motor drives the sorting plate to swing, separating colored and colorless plastics to both sides of the partition. This achieves compression, impurity removal, and sorting of the plastic, greatly improving the sorting efficiency of the equipment. Attached Figure Description

[0013] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-4 This application will be described in detail with reference to the embodiments.
[0015] A multifunctional waste plastic sorting table includes a frame 1 with a drive roller 3 and a driven roller 301 rotatably connected. A conveyor belt 4, angled downwards to the left, connects the drive roller 3 and the driven roller 301. A drive device 4 is connected to one end of the drive roller 3. Mounting side plates 2 are fixedly connected to both sides of the frame 1. Lower pressure rollers 8, evenly distributed and rolling in contact with the upper surface of the conveyor belt 4, are rotatably connected between the mounting side plates 2. The lower pressure rollers 8 are close to each other but do not touch. An axially oriented groove is formed on the outer wall of each lower pressure roller 8. An upper pressure roller device 9 is located above the right side of the conveyor belt 4, and a color recognition component 10 is located above the left end of the conveyor belt 4. A sorting plate 12 is rotatably connected to the lower outer side of the conveyor belt 4. One end of the sorting plate 12 is connected to a servo motor 1201, which can drive the sorting plate 12 to swing back and forth quickly. The servo motor 1201 is electrically connected to the color recognition component 10. Multiple sets of support cylinders 6 are arranged between the active roller 3 and the driven roller 301. The support cylinders 6 support the conveyor belt 4 to ensure that the conveyor belt 4 can fully contact the lower pressure roller 8 and provide sufficient driving force for the lower pressure roller 8. An electromagnet device 7 is arranged inside the support cylinder 6. The electromagnet device 7 can adsorb metal impurities mixed in the plastic to improve the impurity removal effect.
[0016] The upper pressure roller device 9 includes an upper mounting plate 901, on which a hydraulic cylinder device 905 is fixedly connected. The output end of the hydraulic cylinder device 905 is fixedly connected to an upper pressure roller 906 parallel to the lower pressure roller 8. A feeding hopper 902 is opened on the right side of the hydraulic cylinder device 905. A guide plate 903 inclined to the lower left is fixedly connected to the right side of the lower end face of the upper mounting plate 901. A vertically downward protective fence 904 is fixedly connected to the left end of the lower end face of the upper mounting plate 901. The hydraulic cylinder device 905 drives the upper pressure roller 906 to descend and compress the plastic. The protective fence 904 and the guide plate 903 can prevent the plastic from splashing during compression. The guide plate 903 can also guide the plastic to facilitate feeding.
[0017] A feeding baffle 11 is fixedly connected above the sorting plate 12 and is set at an angle to the lower left. A storage box 13 is located directly below the sorting plate 11, and a partition 1301 is fixedly connected in the middle of the storage box 13.
[0018] A scraper 14 is fixedly connected to the right side of the frame 1. The scraper 14 abuts against the right end of the conveyor belt 4 and can clean the impurities attached to the conveyor belt 4.
[0019] The working process of this utility model is as follows: The drive device 5 drives the active roller 3 to rotate, which in turn drives the conveyor belt 4 to move clockwise. The conveyor belt 4 conveys upward, and at the same time, it drives the lower pressure rollers 8 to rotate counterclockwise, feeding plastic from the feed hopper 902 onto the lower pressure rollers 8. The lower pressure rollers 8 cooperate to convey the plastic downward. During the downward conveying process, the plastic tumbles and bounces on the lower pressure rollers 8. At the same time, the hydraulic cylinder device 905 drives the upper pressure roller 906 to compress the plastic. Impurities on the plastic fall off and fall into the conveyor belt 4 through the gaps between the lower pressure rollers 8. The impurities are automatically conveyed upward. During the downward conveying process, the color recognition component 10 can identify the plastic, distinguishing whether it is colored or colorless, and calculate the time it takes for the plastic to detach from the lower pressure rollers 8. When the plastic falls off the pressure roller 8, the servo motor 1201 drives the sorting plate 12 to swing, diverting the colored and colorless plastics to both sides of the partition 1301. When the colored plastic is about to fall off the lower pressure roller 8, the servo motor 1201 drives the sorting plate 12 to swing counterclockwise. When the colored plastic falls between the driven roller 301 and the sorting plate 12, the sorting plate 12 quickly resets and swings back, hitting the plastic to the right side of the partition 1301. When the colorless plastic is about to fall off the lower pressure roller 8, the sorting plate 12 remains stationary and falls onto the sorting plate 12. The servo motor 1201 drives the sorting plate 12 to swing clockwise, quickly pushing the plastic upward away from the sorting plate 12. After being guided by the discharge baffle 11, the plastic falls into the left side of the partition 1301, greatly improving the plastic diversion speed.
[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
