Description

Technical Field

[0001] This utility model relates to the field of waste plastic treatment, specifically a waste plastic recycling pelletizing and dewatering device. Background Technology

[0002] Waste plastics refer to plastic waste generated during production, consumption, use, and disposal that no longer retains its original shape and function. During waste plastic recycling, the crushed and washed plastic fragments are granulated. The surface of the granulated plastic pellets may contain some moisture, which may originate from the washing process or humidity in the air. The presence of moisture can affect the subsequent processing and use of the plastic pellets, therefore dehydration treatment is necessary.

[0003] In existing technologies, to facilitate the processing of waste plastics, a series of treatments are generally carried out, such as crushing, washing, pelletizing, and dehydration. The dehydration step is crucial for facilitating subsequent processing. In most cases, centrifugation or drying methods are used to dehydrate waste plastics. However, centrifugation often leaves water stains on the surface of the waste plastic after dehydration. As for drying, the air outlets of most existing waste plastic drying systems are not easy to move, and the waste plastics are stationary during drying. This means that even when dehydrating waste plastics by drying, water stains can still remain in the inner cavity and dead corners of some waste plastics, which affects subsequent processing and treatment. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, most existing waste plastic drying outlets are not easy to move, and the waste plastic is stationary during drying. This makes it easy for water stains to remain in the inner cavity and dead corners of some waste plastics when dehydrating them by drying, which in turn affects the subsequent processing and treatment of waste plastics. This utility model proposes a waste plastic recycling pelletizing and dehydration device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a waste plastic recycling pelletizing and dewatering device, including a processing box, a servo motor fixedly connected to the bottom of the processing box, the output end of the servo motor passing through the processing box, a collection plate fixedly connected to the inner cavity of the processing box, a vibrating plate slidably connected to the inner cavity of the processing box, a shielding sponge provided on the upper side of the vibrating plate, an auxiliary mechanism provided in the inner cavity of the processing box, and a dewatering mechanism provided on the top of the processing box;

[0006] The dehydration mechanism includes a drive rod, one end of which is fixedly connected to the output end of a servo motor. The surface of the drive rod is slidably connected to the inner cavity of the collecting plate and the vibrating plate. A connecting block is fixedly connected to the surface of the drive rod. A heating box is fixedly connected to the top of the processing box. A heating plate and an exhaust pipe are fixedly connected to the inner cavity of the heating box. An exhaust pump is fixedly connected to the surface of the exhaust pipe. An exhaust corrugated pipe is rotatably connected to the inner cavity of the heating box. One end of the exhaust corrugated pipe passes through the top of the processing box, and the surface of the exhaust corrugated pipe is slidably connected to the inner cavity of the connecting block.

[0007] Preferably, the auxiliary mechanism includes a worm gear, the inner cavity of which is fixedly connected to the surface of a drive rod, a rotating rod rotatably connected to the inner cavity of the processing box, a cam and a worm wheel fixedly connected to the surface of the rotating rod, the teeth of the worm wheel meshing with the teeth of the worm gear, a connecting rod fixedly connected to the bottom of the vibrating plate, the surface of the connecting rod slidingly connected to the inner cavity of the collecting plate, and a rotating wheel rotatably connected to the inner cavity of the connecting rod.

[0008] Preferably, a feed block is fixedly connected to the inner cavity of the processing box, and a pelletizing roller is rotatably connected to the inner cavity of the feed block.

[0009] Preferably, a mounting ring block is fixedly connected to the surface of the drive rod, and a limiting ring block is fixedly connected to the top of the mounting ring block. The surface of the limiting ring block is fixedly connected to the inner cavity of the connecting block.

[0010] Preferably, the inner cavity of the processing box is fixedly connected to a limiting frame and a reinforcing block, the inner cavity of the limiting frame is rotatably connected to the surface of the drive rod, and the inner cavity of the reinforcing block is rotatably connected to the surface of the rotating rod.

[0011] Preferably, the inner cavity of the processing box is provided with a sliding groove, and a slider is fixedly connected to one side of the vibrating plate, the surface of the slider being slidably connected to the inner cavity of the sliding groove.

[0012] Preferably, an absorbent sponge is movably bonded to the top of the collection plate, and a rubber shielding sleeve is fixedly connected to the inner cavity of the treatment box, with the inner cavity of the rubber shielding sleeve fitted onto the surface of the air outlet corrugated pipe.

[0013] The advantages of this utility model are:

[0014] This invention uses a servo motor to drive a drive rod to rotate, which in turn drives a connecting block and a rotating rod to rotate. The connecting block rotates the air outlet bellows, causing the cam to rotate around the center of the rotating rod. This achieves both cyclical drying of waste plastic granules and vibration of the granules, improving the dehydration effect and facilitating subsequent screening. This results in better dehydration, reducing water residue in hard-to-reach areas of the waste plastic, and simultaneously performing screening, thus improving the efficiency of waste plastic processing. It also solves the problems of existing waste plastic drying methods where the air outlet is not easily movable, and the waste plastic remains stationary during drying, leading to water residue in the inner cavity and hard-to-reach areas, which affects subsequent processing.

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a waste plastic recycling pelletizing and dewatering device. (Refer to...) Figure 1 and Figure 3 A waste plastic recycling pelletizing and dewatering device includes a processing box 1, a servo motor 2 fixedly connected to the bottom of the processing box 1, the output end of the servo motor 2 passing through the processing box 1, a collection plate 16 fixedly connected to the inner cavity of the processing box 1, a vibrating plate 6 slidably connected to the inner cavity of the processing box 1, a shielding sponge 7 provided on the upper side of the vibrating plate 6, an auxiliary mechanism 5 provided in the inner cavity of the processing box 1, and a dewatering mechanism 4 provided on the top of the processing box 1.

[0025] The dehydration mechanism 4 includes a drive rod 401. One end of the drive rod 401 is fixedly connected to the output end of the servo motor 2. The surface of the drive rod 401 is slidably connected to the inner cavity of the collecting plate 16 and the vibrating plate 6. A connecting block 402 is fixedly connected to the surface of the drive rod 401. A heating box 403 is fixedly connected to the top of the processing box 1. A heating plate 406 and an air extraction pipe 404 are fixedly connected to the inner cavity of the heating box 403. An air extraction pump 405 is fixedly connected to the surface of the air extraction pipe 404. An air outlet bellows 407 is rotatably connected to the inner cavity of the heating box 403. One end of the air outlet bellows 407 passes through the top of the processing box 1. The surface of the air outlet bellows 407 is slidably connected to the inner cavity of the connecting block 402.

[0026] The vibrating plate 6 connected inside the processing box 1 can temporarily place the pelletized waste plastic. The waste plastic is dehydrated through the cooperation of the shielding sponge 7, the dewatering mechanism 4, and the auxiliary mechanism 5. The shielding sponge 7 is only placed on top of the vibrating plate 6, which makes it easy to remove the shielding sponge 7. The shielding sponge 7 can be removed after dewatering is completed. Then the pelletized waste plastic is screened by the vibrating plate 6, so that larger pieces of plastic can be successfully screened by the vibrating plate 6, which makes it convenient for the staff to pelletize it again later.

[0027] In addition, the servo motor 2 can drive the connecting block 402 to rotate via the drive rod 401 through its own operation. The air pump 405 connected to the top of the heating box 403 can draw external air into the interior of the heating box 403 through the air extraction pipe 404 through its own operation. The extracted air will be heated by the heating plate 406 and flow out through the air outlet bellows 407. While the connecting block 402 is rotating, it can drive the air outlet bellows 407 to rotate together around the center of the drive rod 401, thereby realizing the drying and dehydration of the waste plastic placed on the top of the vibrating plate 6. Through the continuous rotation of the air outlet bellows 407, the dehydration effect of the waste plastic during drying can be better.

[0028] Reference Figure 3 and Figure 4 The auxiliary mechanism 5 includes a worm gear 505, the inner cavity of which is fixedly connected to the surface of the drive rod 401. A rotating rod 506 is rotatably connected to the inner cavity of the processing box 1. A cam 502 and a worm wheel 501 are fixedly connected to the surface of the rotating rod 506. The teeth of the worm wheel 501 mesh with the teeth of the worm gear 505. A connecting rod 503 is fixedly connected to the bottom of the vibrating plate 6. The surface of the connecting rod 503 is slidably connected to the inner cavity of the collecting plate 16. A rotating wheel 504 is rotatably connected to the inner cavity of the connecting rod 503. While the drive rod 401 rotates, the meshing of the worm gear 505 and the worm wheel 501 can further enhance its performance. This drives the worm gear 501, which in turn drives the cam 502 to rotate via the rotating rod 506. As the cam 502 rotates, it continuously pushes the rotating wheel 504, causing the rotating wheel 504 and the connecting rod 503 to move up and down in tandem, following the rotation and push of the cam 502. When the vibrating plate 6 moves up and down in tandem with the connecting rod 503, it enables the waste plastic to vibrate and tumble continuously while being dried and dehydrated, thereby improving the dehydration effect of the waste plastic and reducing the possibility of a large amount of water stains remaining in the waste plastic.

[0029] Reference Figure 2 and Figure 3The inner cavity of the processing box 1 is fixedly connected to the feeding block 3, and the inner cavity of the feeding block 3 is rotatably connected to the pelletizing roller 11. The pelletizing roller 11 connected inside the feeding block 3 is connected to an external motor, which drives the pelletizing roller 11. When the pelletizing roller 11 rotates, it can smoothly pelletize the waste plastic put into the feeding block 3, thereby increasing the convenience for workers when they need to pelletize and dehydrate the waste plastic. The pelletizing roller 11 is a prior art in this field, so it will not be described in detail here.

[0030] Reference Figure 3 and Figure 5 A mounting ring block 17 is fixedly connected to the surface of the drive rod 401. A limiting ring block 10 is fixedly connected to the top of the mounting ring block 17. The surface of the limiting ring block 10 is fixedly connected to the inner cavity of the connecting block 402. The drive rod 401 can install and fix the limiting ring block 10 through the mounting ring block 17. The limiting ring block 10 can support and fix the rotation and use of the connecting block 402 through its connection with the connecting block 402, so that it is not easy to shake, tilt or fall off when rotating.

[0031] Reference Figure 4 and Figure 5 The inner cavity of the processing box 1 is fixedly connected to a limiting frame 14 and a reinforcing block 15. The inner cavity of the limiting frame 14 is rotatably connected to the surface of the drive rod 401, and the inner cavity of the reinforcing block 15 is rotatably connected to the surface of the rotating rod 506. The limiting frame 14 can provide certain support and limit the rotation of the drive rod 401, reducing the swaying or tilting during rotation. The reinforcing block 15 can also provide support and reinforcement for the rotating rod 506, further increasing the stability of the rotating rod 506 during rotation.

[0032] Reference Figure 3 and Figure 4 The inner cavity of the processing box 1 is provided with a sliding groove 8. A slider 9 is fixedly connected to one side of the vibrating plate 6. The surface of the slider 9 is slidably connected to the inner cavity of the sliding groove 8. The connection between the sliding groove 8 and the slider 9 makes the movement of the vibrating plate 6 smooth and stable enough when it moves up and down by the rotation of the cam 502, and it is not easy for it to tilt during movement.

[0033] Reference Figure 2 and Figure 3A water-absorbing sponge 13 is movably bonded to the top of the collection plate 16. A rubber shielding sleeve 12 is fixedly connected to the inner cavity of the treatment box 1. The inner cavity of the rubber shielding sleeve 12 is fitted onto the surface of the air outlet corrugated pipe 407. The water-absorbing sponge 13 can further absorb the water stains on the surface of the waste plastic particles after filtration by the vibrating plate 6, thereby greatly increasing the dehydration effect on the waste plastic. Since the air outlet corrugated pipe 407 is rotatably connected to the heating box 403, and the surface of the air outlet corrugated pipe 407 is also rotatably connected to the inner cavity of the treatment box 1, the setting of the water-absorbing sponge 13 can not only strengthen the stability of the rotation and use of the air outlet corrugated pipe 407, but also play a certain role in shielding and sealing the gap between the air outlet corrugated pipe 407 and the treatment box 1.

[0034] Working Principle: When using this device, the operator can add the cleaned waste plastic to the inside of the feed block 3. The waste plastic added to the feed block 3 will be cut into pieces and pellets by the pelletizing roller 11. The pelletized waste plastic will fall onto the top of the shielding sponge 7. At this time, the operator can start the servo motor 2, the heating plate 406, and the vacuum pump 405. When the servo motor 2 is operating, it will drive the drive rod 401 to rotate. The rotation of the drive rod 401 can simultaneously drive the connecting block 402 and... The worm gear 505 rotates, and the rotation of the connecting block 402 can smoothly drive the air outlet bellows 407 to rotate. At this time, due to the operation of the air pump 405, the external air will be sucked into the interior of the heating box 403 and heated by the heating plate 406. Then it will be discharged through the air outlet bellows 407, so that the air outlet bellows 407 can blow out hot air while rotating with the connecting block 402, thereby drying and dehydrating the waste plastic. At the same time, the shielding sponge 7 can also absorb water stains on the surface of the waste plastic.

[0035] At the same time, the worm 505 can drive the rotating rod 506 and the cam 502 to rotate by meshing with the worm wheel 501. When the cam 502 rotates, it can smoothly and continuously push the connecting rod 503, causing the vibrating plate 6 to move up and down, thereby vibrating the waste plastic on the top of the vibrating plate 6 and improving the effect of the air outlet bellows 407 in dewatering waste plastic particles.

[0036] After the waste plastic is dehydrated, the staff can remove the shielding sponge 7 from the top of the vibrating plate 6. After the shielding sponge 7 is removed, the up-and-down reciprocating motion of the vibrating plate 6 will screen the pelletized waste plastic, allowing smaller waste plastic pellets to fall smoothly to the top of the collection plate 16, while larger waste plastic pellets will remain on the top of the vibrating plate 6, making it easier to re-pelletize and pulverize the larger waste plastic pellets. At the same time, the air outlet corrugated pipe 407 can further dry the larger waste plastic pellets while the vibrating plate 6 is screening the waste plastic, thereby reducing the water stains remaining in the larger waste plastic pellets.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
