Description

Technical Field

[0001] This invention relates to the field of plastic recycling technology, and in particular to a plastic waste recycling device. Background Technology

[0002] Plastic products are widely used in today's society, but their slow biodegradability places a heavy pollution burden on the environment. Large quantities of plastic are carelessly discarded, causing pollution and severely damaging the ecosystem. In the face of environmental problems caused by plastic waste, recycling plastic products can not only effectively reduce environmental pollution but also conserve valuable resources, thus promoting sustainable development goals. We can transform waste plastic products into new raw materials or products, thereby reducing our dependence on and exploitation of natural resources.

[0003] The current method for recycling plastic waste involves crushing it into plastic pellets. However, the size of the plastic pellets is uncontrollable during crushing, resulting in inconsistent pellet sizes and poor mixing efficiency. Furthermore, waste plastic products often contain metals, which greatly increases the difficulty of screening. Ordinary screening methods are also characterized by low precision, poor effectiveness, and slow speed, leading to overall low screening efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by providing a plastic waste recycling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A plastic waste recycling device includes a base, a collection bin, and a screen plate. The screen plate is inclined and has two sets of baffles installed at equal intervals. The two sets of baffles divide the collection bin into three screening surfaces. The screening surfaces are evenly provided with fine sieve holes, medium sieve holes, and coarse sieve holes from top to bottom. An elastic component is provided between the base and the screen plate, and a vibration component is provided at the bottom of the screen plate.

[0006] Preferably, the vibration assembly includes a swing base, a rotating rod, a guide rod, a vibrating rod, a fixed base, and a guide cylinder. The guide cylinder is fixedly installed at the bottom of the screen plate. The guide rod is slidably connected to the inner wall of the guide cylinder, and the bottom of the guide rod is welded to the top center of the fixed base. Two sets of vibrating rods are provided, and the two sets of vibrating rods are symmetrically installed on both sides of the top of the fixed base. The fixed base and the swing base are rotatably connected by a rotating rod. Swing components are provided on both sides of the bottom of the swing base.

[0007] Preferably, the swing assembly includes a base, a second motor, a bearing, and a rotating arm. A swing groove is provided on one side of the base. The base is fixedly installed on the inner wall of one side of the swing groove by bolts. The second motor is fixedly installed on the inner wall of the base. Two sets of rotating arms are provided. Swing blocks are welded to the opposite ends of the two sets of rotating arms. The two sets of swing blocks are rotatably connected to the outer walls on both sides of the bottom of the swing base. The output end of the second motor is fixedly connected to one end of one set of rotating arms. The other set of rotating arms is rotatably connected to the inner wall of the other side of the swing groove through a bearing.

[0008] Preferably, a first feeding seat, a second feeding seat, and a third feeding seat are sequentially provided on the bottom sides of the fine sieve holes, medium sieve holes, and coarse sieve holes on the sieve plate, and the bottoms of the first feeding seat, the second feeding seat, and the third feeding seat are all fixedly connected to the base through connecting arms.

[0009] Preferably, the elastic component includes a shock-absorbing spring and a buffer seat. The buffer seat is provided in four sets, and the four sets of buffer seats are fixedly installed at the four corners of the top surface of the base. The top of the four sets of buffer seats is provided with a buffer cavity. The two ends of the shock-absorbing spring are respectively fixedly connected to the sieve plate and the center of the bottom side of the buffer cavity.

[0010] Preferably, the inner wall of the collection chamber is divided into three collection cavities by two sets of partitions. The three collection cavities are located directly below the first, second, and third feeding seats in sequence. The first, second, and third feeding seats are all inclined towards the collection chamber. The second and third feeding seats have successively extended sections near the collection chamber. The extended sections are evenly provided with fine sieve holes and medium sieve holes. Inclined guide seats are fixedly installed at the bottom of the extended sections of the second and third feeding seats. The lowest point of the guide seats at the bottom of the second and third feeding seats is sequentially guided to the collection cavity directly below the first and second feeding seats.

[0011] Preferably, the top outer wall of the sieve plate is bolted to a bracket, and the top of the bracket is fixedly connected to a feeding seat via a fixing arm. The inner wall of the feeding seat decreases in size from top to bottom, and a semi-magnetic roller is provided on the bottom feeding port side of the feeding seat. Side plates are fixedly installed on both sides of the outer wall of the semi-magnetic roller. Several sets of guide plates are equidistantly installed on the outer wall of the semi-magnetic roller between the two sets of side plates.

The center of the other set of side plates is connected to a guide rod via a bearing, and one end of the guide rod is rotatably connected to the inner wall of the bracket.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The semi-magnetic roller can be magnetized when it is close to the screen plate. At this time, it can attract metal mixed in the plastic pellets and prevent metal from being mixed into the plastic pellets. When the semi-magnetic roller is away from the screen plate, its magnetism disappears and the metal can be discharged. The first motor drives it to run back and forth, so as to continuously screen the plastic pellets in the feed seat. The side plate and guide plate are used to drive the plastic pellets to flow to the screen plate in sequence. 2. The fine, medium, and coarse sieve holes on the sieve plate are used to distinguish plastic particles into three different sizes. The baffle is used to slow down the flow of unscreened particles. The sieve plate is driven to vibrate by the vibration component, and the elastic component is used to drive the sieve plate and the plastic particles on the sieve plate to vibrate and accelerate the flow, so as to prevent the surface particles from not being screened by the sieve holes and to prevent the plastic particles from clogging the sieve holes, thereby improving the accuracy and efficiency of screening. 3. The three sets of collection chambers in the collection bin are used to collect three different sizes of plastic granules separately. By setting a fine screen and a medium screen at the discharge end of the second and third discharge seats, the plastic granules on the first and second discharge seats can be screened a second time to improve the screening accuracy. The screened plastic granules are collected into the collection chamber through the guide seat. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-6 This invention provides an embodiment of a plastic waste recycling device, comprising a base 24, a collection bin 1, and a screen plate 2. The screen plate 2 is inclined, and two sets of baffles 3 are equidistantly installed on the screen plate 2, dividing the collection bin 1 into three screening surfaces. The screening surfaces are uniformly provided with through-holes 30 (fine screen), 31 (medium screen), and 32 (coarse screen) from top to bottom. An elastic component is provided between the base 24 and the screen plate 2, and a vibration component is provided at the bottom of the screen plate 2. After being recycled and crushed, the plastic particles are formed into plastic granules of different sizes. To avoid mixing plastics and resulting in poor plastic quality, a sieve plate 2 is used to filter plastic particles. The sieve plate 2 has fine sieve holes 30, medium sieve holes 31, and coarse sieve holes 32 to separate the plastic particles into three different sizes. The baffle plate 3 is used to slow down the flow of unscreened particles. The sieve plate 2 is driven to vibrate by a vibration component, which, together with the elastic component, drives the sieve plate 2 and the plastic particles on it to vibrate and accelerate their flow. This prevents floating particles, i.e., surface particles, from being screened and also prevents plastic particles from clogging the sieve holes, thereby improving the accuracy and efficiency of screening.

[0017] Specifically, the vibration assembly includes a swing base 15, a rotating rod 16, a guide rod 17, a vibrating rod 18, a fixed base 19, and a guide cylinder 20. The guide cylinder 20 is fixedly installed at the bottom of the screen plate 2. The guide rod 17 is slidably connected to the inner wall of the guide cylinder 20, and the bottom of the guide rod 17 is welded to the top center of the fixed base 19. Two sets of vibrating rods 18 are provided, and the two sets of vibrating rods 18 are symmetrically installed on both sides of the top of the fixed base 19. The fixed base 19 and the swing base 15 are rotatably connected through the rotating rod 16. Swinging components are provided on both sides of the bottom of the swing base 15. The swinging components drive the swing base 15 to swing. Under the swing of the swing base 15, the fixed base 19 moves, which in turn drives the guide rod 17 to reciprocate on the inner wall of the guide cylinder 20. At the same time, the vibrating rods 18 on both sides of the guide rod 17 continuously strike the bottom of the screen plate 2 to generate vibration.

[0018] Specifically, the swing assembly includes a base 11, a second motor 12, a bearing 13, and a rotating arm 14. A swing groove is provided on one side of the base 24. The base 11 is fixedly installed on the inner wall of one side of the swing groove by bolts. The second motor 12 is fixedly installed on the inner wall of the base 11. Two sets of rotating arms 14 are provided. Swing blocks are welded to the opposite ends of the two sets of rotating arms 14. The two sets of swing blocks are rotatably connected to the outer walls on both sides of the bottom of the swing base 15. The output end of the second motor 12 is fixedly connected to one end of one set of rotating arms 14. The other set of rotating arms 14 is rotatably connected to the inner wall of the other side of the swing groove through the bearing 13. The rotation of the second motor 12 can drive the rotating arm 14 to rotate. The rotation of the rotating arm 14 drives the entire vibration assembly to operate and generate vibration.

[0019] Specifically, a first feeding seat 26, a second feeding seat 27, and a third feeding seat 28 are sequentially arranged on the bottom sides of the fine sieve hole 30, the medium sieve hole 31, and the coarse sieve hole 32 on the sieve plate 2. The bottoms of the first feeding seat 26, the second feeding seat 27, and the third feeding seat 28 are all fixedly connected to the base 24 through the connecting arm 29. The first feeding seat 26, the second feeding seat 27, and the third feeding seat 28 are used to separately discharge the screened plastic particles. The first feeding seat 26, the second feeding seat 27, and the third feeding seat 28 are designed with an inclination so that the plastic particles can slide out by their own gravity. The first feeding seat 26, the second feeding seat 27, and the third feeding seat 28 are equipped with anti-splash plates on both sides to prevent plastic particles from jumping out when discharging.

[0020] Specifically, the elastic component includes a shock-absorbing spring 21 and a buffer seat 22. There are four sets of buffer seats 22, which are fixedly installed at the four corners of the top surface of the base 24. Each set of buffer seats 22 has a buffer cavity at its top. The two ends of the shock-absorbing spring 21 are fixedly connected to the screen plate 2 and the center of the bottom side of the buffer cavity, respectively. When the vibrating rod 18 continuously strikes the screen plate 2 to vibrate, the shock-absorbing spring 21 at the bottom of the screen plate 2 is used to support the screen plate 2 to move up and down reciprocally, and the buffer seat 22 is used to support the shock-absorbing spring 21 to bounce stably.

[0021] Specifically, the inner wall of the collection chamber 1 is divided into three collection chambers by two sets of partitions 4. The three collection chambers are located directly below the first discharge seat 26, the second discharge seat 27, and the third discharge seat 28. The first discharge seat 26, the second discharge seat 27, and the third discharge seat 28 are all inclined towards the collection chamber 1. The second discharge seat 27 and the third discharge seat 28 have successively extended sections on the side of the collection chamber 1. The extended sections are evenly provided with fine sieve holes 30 and medium sieve holes 31, and inclined installations are fixed at the bottom of the extended sections of the second discharge seat 27 and the third discharge seat 28. The lowest point of the guide seat 25 at the bottom of the first feeding seat 26 and the second feeding seat 27 and the third feeding seat 28 is sequentially guided to the collection chamber directly below the first feeding seat 26 and the second feeding seat 27. The three sets of collection chambers in the collection chamber 1 are used to collect three different sizes of plastic granules separately. By setting a fine screen hole 30 and a medium screen hole 31 at the material dropping end of the second feeding seat 27 and the third feeding seat 28, the plastic granules on the first feeding seat 26 and the second feeding seat 27 can be screened a second time to improve the accuracy of the screening. The screened plastic granules are collected into the collection chamber through the guide seat 25.

[0022] Specifically, a bracket 6 is bolted to the top outer wall of the screen plate 2. A feeding seat 5 is fixedly connected to the top of the bracket 6 via a fixing arm 23. The inner wall of the feeding seat 5 decreases in size from top to bottom. A semi-magnetic roller 8 is provided at the bottom of the feeding seat 5 near the feeding port. Side plates 10 are fixedly installed on both sides of the outer wall of the semi-magnetic roller 8. Several sets of guide plates 9 are equidistantly installed on the outer wall of the semi-magnetic roller 8 between the two sets of side plates 10. The center of the outer wall of one set of side plates 10 is fixedly connected to the output end of the first motor 7 via a support rod. The first motor 7 is fixedly installed on one side of the outer wall of the bracket 6. The center of the other set of side plates 10 is connected to a guide rod via a bearing. One end of the guide rod is rotatably connected to the inner wall of the bracket for feeding. Seat 5 is used to collect the plastic granules to be screened. During screening, the first motor 7 is started, and the rotation of the first motor 7 drives the semi-magnetic drum 8 to rotate. The side plate 10 and the guide plate 9 are used to drive the plastic granules to flow sequentially onto the screen plate 2. One end of the guide rod extends into the interior of the semi-magnetic drum 8 and is connected to a permanent magnet. The permanent magnet makes half of the interior of the semi-magnetic drum 8 magnetic and half non-magnetic, and the strong magnetic area of ​​the magnet is close to the side of the screen plate 2. During the operation of the semi-magnetic drum 8, the metal will first pass through the strong magnetic area. At this time, the metal mixed in with the plastic granules can be adsorbed, preventing the metal from being mixed into the plastic granules. When the metal moves from the strong magnetic area to the non-magnetic area, the centrifugal force of the rotation can discharge the metal, thus reciprocating.

[0023] Working principle: The feeding seat 5 is used to collect the plastic granules to be screened. During screening, the first motor 7 is started, and the rotation of the first motor 7 drives the semi-magnetic roller 8 to rotate. The side plate 10 and the guide plate 9 are used to drive the plastic granules to flow sequentially onto the screen plate 2. During the operation of the semi-magnetic roller 8, it becomes magnetic when it is close to the screen plate 2, which can adsorb metal mixed in with the plastic granules and prevent metal from being mixed into the plastic granules. When the semi-magnetic roller 8 is away from the screen plate 2, it becomes non-magnetic, which can discharge the metal. This process is repeated. After the plastic particles are recycled and crushed, they are formed into plastic particles of different sizes. To avoid mixing and resulting in poor plastic condition, the plastic particles are filtered through the screen plate 2. The fine screen holes 30, medium screen holes 31 and coarse screen holes 32 on the screen plate 2 are used to filter the plastic particles. The three sizes of plastic particles are distinguished by the baffle 3, which is used to slow down the flow of unscreened particles. The vibrating component drives the screen plate 2 to vibrate, and the elastic component drives the screen plate 2 and the plastic particles on the screen plate 2 to vibrate and accelerate the flow. This prevents floating particles, i.e., particles on the surface, from being screened through the screen holes and also prevents plastic particles from clogging the screen holes, thereby improving the accuracy and efficiency of screening. The three sets of collection chambers in the collection chamber 1 are used to collect the three different sizes of plastic particles separately. By setting a fine screen hole 30 and a medium screen hole 31 at the discharge end of the second discharge seat 27 and the third discharge seat 28, the plastic particles on the first discharge seat 26 and the second discharge seat 27 can be screened a second time to improve the accuracy of screening. The screened plastic particles are collected into the collection chamber through the guide seat 25.

[0024] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
