Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic waste recycling, in particular to a vibrating feeder for sorting plastic waste. Background Art
[0002] Waste recycling can reduce environmental pollution and recycle waste, particularly effectively processing naturally indegradable chemicals like plastics. Prior art already has machines for recycling beverage bottles. These machines allow users to place empty plastic bottles into the machine's waste collection port, effectively recycling empty bottles but lack the ability to sort and identify plastics. This is illustrated by the Chinese utility model patent "Electronic Waste and Plastic Waste Recycling Machine" (Application No. 201420159450.0).
[0003] Plastics sorting through visual inspection is already being used, such as in the Chinese invention patent "Artificial Intelligence Waste Plastic Bottle Sorting Method" (Application No. 201910421311.8). However, visual inspection requires that waste plastics do not overlap and are spaced a certain distance apart to facilitate visual identification and sorting. Furthermore, waste plastics that are placed vertically or at a steep angle on the conveyor belt will vibrate, leading to inaccurate visual inspection and identification, reducing the success rate of sorting. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the present invention provides a vibrating feeder for sorting plastic waste. The present invention reduces the occurrence of vibration by adding functional components such as rotating separation teeth, an acceleration slide plate, and a buffering smooth plate.
[0005] The technical solution of the utility model is: a vibrating feeder for sorting plastic waste, comprising a feeding device, a vibration spring, a motor mounting seat, a vibration motor, and a frame, the feeding device being mounted on the frame through the vibration spring, a motor mounting seat being arranged at the lower part of the feeding device, and the vibration motor being mounted on the motor mounting seat, characterized in that: the feeding device comprises a hopper, rotating separation teeth, a vibration separation plate, an acceleration slide plate, and a buffer smooth plate, multiple rows of rotating separation teeth are arranged at the rear of the hopper, a vibration separation plate is arranged at the rear of the rotating separation teeth, an acceleration slide plate is arranged at the rear of the vibration separation plate, and a buffer smooth plate is arranged at the rear of the acceleration slide plate; wherein the hopper and the vibration separation plate are inclined at an angle of 3° to 10° with the horizontal plane, the acceleration slide plate is inclined at an angle of 40° to 60° with the horizontal plane, and the buffer smooth plate is inclined at an angle of 0° to 5° with the horizontal plane.
[0006] According to the vibrating feeder for sorting plastic waste as described above, the feature is that the feeding device is mounted on the frame via four vibration springs.
[0007] According to the vibrating feeder for sorting plastic waste as described above, the feature is that the vibration motor is at a 45° angle to the bottom plane of the feeding device.
[0008] According to the vibrating feeder for sorting plastic waste as described above, the feature is that an adjusting foot is provided at the bottom of the frame.
[0009] According to the vibrating feeder for sorting plastic waste as described above, it is characterized in that the rotating separation teeth are distributed in two rows.
[0010] According to the vibrating feeder for sorting plastic waste as described above, it is characterized in that the rotating separation teeth rotate slowly by the vibration provided by the vibration motor.
[0011] According to the vibrating feeder for sorting plastic waste as described above, the feature is that the rotating separation teeth are controlled to rotate by an external motor, and the rotation directions of the two rows of rotating separation teeth are opposite.
[0012] The beneficial effects of this utility model include adjustable overall inclination of the feeding device, facilitating fine-tuning of the equipment under various conditions. This allows plastic waste to slide downward in a relatively even distribution. This ensures uniform distribution of plastic waste flowing onto the conveyor belt, facilitating even opening of the high-speed on-off valves in the air path during subsequent separation and sorting, thereby improving sorting efficiency and accuracy. This ensures that plastic bottles on the fast-moving conveyor belt stop shaking as quickly as possible, providing optimal measurement conditions for subsequent visual inspection.

[0017] The technical solution of the present utility model is further described below with reference to the accompanying drawings.
[0018] like Figure 1 and Figure 2 As shown, the utility model is a vibrating feeder for sorting plastic waste, which includes a feeding device 1, a vibration spring 2, a motor mounting base 3, a vibration motor 4, and a frame 5. The feeding device 1 is mounted on the frame 5 through the vibration spring 2. Figure 1 As shown, the feeding device 1 is mounted on the frame 5 via four vibration springs 2. A motor mounting base 3 is provided at the bottom of the feeding device 1. The motor mounting base 3 is mounted with a vibration motor 4. The vibration of the vibration motor 4 causes the entire feeding device 1 to vibrate while suspended on the vibration springs 2. After the preferred installation of the present invention, the vibration motor 4 is at a 45° angle to the bottom plane of the feeding device 1, which provides the best vibration effect. Figure 1 and Figure 2 As shown, the bottom of the frame 5 of the present invention is preferably provided with an adjusting foot 6. By adjusting the height of the adjusting foot 6, the overall inclination of the feeding device 1 can be adjusted, thereby facilitating fine-tuning of the equipment in various states.
[0019] like Figure 3 As shown, the feeding device 1 of the present invention includes a hopper 11, rotating separation teeth 12, a vibrating separation plate 13, an acceleration slide 14, and a buffer smooth plate 15. Multiple rows of rotating separation teeth 12 are provided at the rear of the hopper 11, a vibrating separation plate 13 is provided at the rear of the rotating separation teeth 12, an acceleration slide 14 is provided at the rear of the vibrating separation plate 13, and a buffer smooth plate 15 is provided at the rear of the acceleration slide 14. The plastic waste output by the buffer smooth plate 15 is conveyed to the conveyor belt for visual inspection to classify and identify the plastics. The hopper 11 and the vibrating separation plate 13 are tilted at an angle of 3° to 10° with respect to the horizontal plane. The tilt angle can be adjusted by adjusting the base 6 so that the plastic waste can slide downward in a relatively even distribution during the vibration of the bottom vibration motor 4.
[0020] like Figure 2 and Figure 3 As shown, the rotating separation teeth 12 of the present invention are distributed in two rows, and can be rotated slowly by the vibration provided by the vibration motor 4, or can be controlled to rotate more quickly by an external motor. In this way, the plastic waste from the vibration of the silo 11 is separated due to the impact of the rotating separation teeth 12, ensuring that there is no overlapping of the plastic waste after separation. When the rotation of the rotating separation teeth 12 is controlled externally, the rotation direction is preferably opposite, such as the front row rotates clockwise, and the back row rotates counterclockwise. This can make the plastic waste more evenly distributed on the vibration separation plate 13, and the plastic waste flowing into the conveyor belt is evenly distributed, which is convenient for the uniform opening and use of the high-speed on-off valve of the air path during subsequent separation and sorting, thereby improving the sorting efficiency and accuracy.
[0021] like Figure 2 and Figure 3As shown, the acceleration slide 14 of the present invention forms an angle of 40° to 60° with the horizontal plane, and the buffer smooth plate 15 forms an angle of 0° to 5° with the horizontal plane. In this way, after the plastic waste slides onto the acceleration slide 14 through the vibrating separation plate 13 and then falls onto the buffer smooth plate 15, the buffer smooth plate 15 changes the speed direction of the plastic bottles to the horizontal direction. This increases the horizontal speed of the input plastic waste, making it less different from the running speed of the conveyor belt. The plastic waste also moves in the same direction as the subsequent conveyor belt in the east direction, ensuring that the plastic bottles stop shaking as soon as possible on the fast-running conveyor belt. Compared to plastic bottles inputted tangentially, after being inputted into the conveyor belt in the tangential direction, the plastic bottles are more likely to shake in the longitudinal direction due to speed inertia, thereby reducing the accuracy of subsequent visual inspection to identify the type of plastic bottles, which is not conducive to the normal and stable operation of the equipment.
[0022] During the working process of the present invention, plastic waste is poured into the hopper 11, and the material is discharged more evenly under the action of the vibration motor 4. The rotating separation teeth 12 further ensure that there is no overlapping of plastic waste. The acceleration slide 14 and the buffer smooth plate 15 are used to reduce the occurrence of jitter, providing better measurement conditions for subsequent visual inspection.
