Description

Technical Field

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

[0002] Plastic recycling refers to the process of collecting, sorting, processing, and reusing waste plastic products. It aims to reduce resource waste and environmental pollution. Bottles made of common plastics such as PET, PE, or PP can be recycled and melted down to produce new products, achieving the circular use of plastics. Plastic screening plays a crucial role in the recycling process, removing impurities and ensuring the quality of the recycled materials.

[0003] Existing plastic recycling screening devices are not equipped with cleaning devices during use, making it impossible to remove stubborn impurities. This can easily result in some small impurities remaining during recycling, which can seriously affect the quality of subsequent plastic recycling processing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a screening device for plastic recycling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screening device for plastic recycling includes a washing assembly. The washing assembly includes a base, a washing tank mounted on top of the base, a moving rail on top of the washing tank, a moving block slidably mounted on the moving rail, a support frame mounted on top of the moving block, a hydraulic cylinder mounted on top of the support frame, a telescopic end of the bottom of the hydraulic cylinder slidably passing through the support frame, a connecting frame mounted on the bottom of the hydraulic cylinder, a connecting block detachably mounted on the connecting frame, a debris collection box at the bottom of the connecting block, several sets of drainage holes arranged sequentially on one side of the debris collection box, a mounting bracket mounted on one side of the washing tank, a drive motor mounted on one side of the mounting bracket, a threaded rod connected to the output end of the drive motor, a threaded block mounted on the threaded rod, the bottom of the threaded block fixed to the support frame, a drain outlet connected to one side of the washing tank, a sealing plug at one end of the drain outlet, and a screening assembly for removing impurities mounted on one side of the base.

[0007] As a further embodiment of this utility model: the screening assembly includes a screening chamber, which is installed on the top of the base. Several sets of fixing blocks are symmetrically installed on the inner walls of both sides of the screening chamber. A vibration motor is installed on the top of the fixing blocks. The output end of the vibration motor is connected to a screen plate. Several sets of screen holes are arranged in sequence on the screen plate. A discharge port is provided on one side of the screening chamber. The size and position of the discharge port are adapted to the screen plate. A sealing component for auxiliary screening and a crushing component for crushing are provided on one side of the screening chamber.

[0008] As a further embodiment of this utility model: the crushing component includes a motor chamber, which is installed on one side of the screening chamber. The output end of the motor chamber is connected to several sets of transmission shafts. One end of the transmission shaft is rotatably installed through the screening chamber, and several sets of crushing blades are arranged sequentially on the transmission shaft.

[0009] As a further embodiment of this utility model: the enclosed component includes a fixed frame, which is installed on one side of the screening chamber. An adjusting motor is installed on one side of the fixed frame, and the output end of the adjusting motor is connected to an installation shaft. One end of the installation shaft is rotatably installed through the fixed frame, and a closing baffle is installed on the installation shaft. The size and position of the closing baffle are adapted to the discharge port of the screening chamber.

[0010] As a further improvement of this utility model: the inner walls on both sides of the screening chamber are symmetrically provided with mounting grooves, and a slider is slidably installed through the mounting grooves.

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0024] A screening device for plastic recycling, such as Figure 1-4As shown, the system includes a cleaning assembly, which includes a base 1. A cleaning tank 21 is mounted on the top of the base 1. A moving rail 18 is provided on the top of the cleaning tank 21. A moving block 17 is slidably mounted on the moving rail 18. A support frame 16 is mounted on the top of the moving block 17. A hydraulic cylinder 12 is provided on the top of the support frame 16. The telescopic end of the bottom of the hydraulic cylinder 12 can slide through the support frame 16. A connecting frame 11 is mounted on the bottom of the hydraulic cylinder 12. A connecting block is detachably mounted on the connecting frame 11. A debris collection box 22 is provided at the bottom of the connecting block. Several sets of drainage holes are arranged sequentially on one side of the debris collection box 22. An installation bracket 25 is mounted on one side of the cleaning tank 21. A drive motor 14 is mounted on one side of the installation bracket 25. A threaded rod 13 is connected to the output end of one side of the drive motor 14. A threaded block 15 is mounted on the threaded rod 13. The bottom of the threaded block 15 is fixed to the support frame 16. A drain outlet 19 is connected to one side of the cleaning tank 21. A sealing plug is provided at one end of the drain outlet 19. A screening assembly for removing impurities is provided on one side of the base 1.

[0025] When in use, water can be added to the cleaning tank 21. After adding water, the crushed plastic sheets can be poured into the cleaning tank 21. The plastic sheets can be cleaned by soaking in water. Soaking and cleaning can remove stubborn small impurities, thus avoiding the situation where small impurities remain during recycling and preventing the impact on the subsequent processing quality of plastic recycling. During soaking and cleaning, the plastic sheets sink to the bottom of the cleaning tank 21, and the small impurities that are washed off will float on the water surface. The drive motor 14 can be started to control the rotation of the threaded rod 13. The rotation of the threaded rod 13 can drive the threaded block 15 to move. When the threaded block 15 moves, the moving block 17 can be controlled to slide on the moving rail 18, thereby controlling the movement of the support frame 16. The movement of the debris collection box 22 can be controlled synchronously. The height of the debris collection box 22 can be adjusted by the hydraulic cylinder 12. After adjusting to a suitable height, the movement of the debris collection box 22 can remove the small impurities floating on the water surface, thus avoiding the re-contamination of impurities when the plastic sheets are taken out after cleaning.

[0026] The screening assembly includes a screening chamber 3, which is installed on the top of the base 1. Several sets of fixing blocks 28 are symmetrically installed on the inner walls of both sides of the screening chamber 3. A vibration motor 27 is installed on the top of the fixing blocks 28. The output end of the vibration motor 27 is connected to a screen plate 23. Several sets of screen holes are arranged in sequence on the screen plate 23. A discharge port is opened on one side of the screening chamber 3. The size and position of the discharge port are adapted to the screen plate 23. A closed assembly for auxiliary screening and a crushing assembly for crushing are provided on one side of the screening chamber 3.

[0027] When in use, plastic sheets can be added into the screening chamber 3. The crushing component can be started to crush them. After crushing, the plastic sheets fall onto the screen plate 23. The vibrating motor 27 can be started to drive the screen plate 23 to vibrate. The screen plate 23 can be vibrated to screen the crushed plastic sheets. Small debris and impurities can be removed by using the screen holes. The plastic sheets with impurities removed accumulate on the screen plate 23. The screened plastic sheets can be removed for cleaning by controlling the opening of the discharge port through the sealing component.

[0028] The crushing assembly includes a motor chamber 8, which is installed on one side of the screening chamber 3. The output end of the motor chamber 8 is connected to several sets of drive shafts 26. One end of the drive shaft 26 is rotatably installed through the screening chamber 3. Several sets of crushing blades 24 are arranged sequentially on the drive shaft 26.

[0029] When the plastic sheet is added to the screening chamber 3, the motor in the motor chamber 8 can be started to control the rotation of the transmission shaft 26 and the crushing blade 24. The plastic sheet can be crushed by the rotation of several sets of crushing blades 24. The crushing process makes it easy to recycle the plastic sheet and also facilitates screening and impurity removal.

[0030] The enclosed assembly includes a fixed frame 6, which is installed on one side of the screening chamber 3. An adjusting motor 7 is installed on one side of the fixed frame 6. An installation shaft 10 is connected to the output end of the adjusting motor 7. One end of the installation shaft 10 is rotatably installed through the fixed frame 6. A closing baffle 5 is installed on the installation shaft 10. The size and position of the closing baffle 5 are adapted to the discharge port of the screening chamber 3.

[0031] During use, the installation shaft 10 can be rotated by adjusting the motor 7, thereby synchronously controlling the rotation of the closed baffle 5. By switching between forward and reverse rotation, the rotation direction of the closed baffle 5 can be controlled to open and close the discharge port. During screening, the discharge port is closed to avoid affecting normal screening. After screening is completed, the discharge port is opened to collect the material.

[0032] In order to collect the impurities screened out, such as Figure 1 , 2 As shown, the inner walls on both sides of the screening chamber 3 are symmetrically provided with mounting grooves, and a slider 4 is slidably installed through the mounting grooves. A collection box 2 is provided on one side of the slider 4, and the size of the collection box 2 is adapted to the screening chamber 3.

[0033] When in use, the collection box 2 can be installed by installing the slider 4 into the installation slot. After installation, the collection box 2 is located below the sieve plate 23. Impurities screened out by the sieve plate 23 can fall into the collection box 2 for collection, which greatly reduces the difficulty of cleaning and can indirectly increase the efficiency of plastic recycling.

[0034] To prevent it from slipping out during movement, such as Figure 3 As shown, a plug 20 is installed at the end of the moving rail 18, and the diameter of the plug 20 is larger than the diameter of the moving rail 18.

[0035] During use, the plugs 20 installed at both ends of the moving rail 18 can act as a sealing and protection mechanism, thereby preventing the moving block 17 from detaching from the moving rail 18 when it is driven to move, thus ensuring normal movement. Example 2

[0036] To avoid splashing when broken, refer to Figure 1 , 2 A screening device for plastic recycling, in this embodiment, is improved from embodiment 1 as follows: an auxiliary frame 9 is installed at the top of the screening chamber 3, and the opening of the auxiliary frame 9 gradually expands from bottom to top;

[0037] When in use, the auxiliary frame 9, which has an upwardly tilted opening, can assist in the crushing process, preventing plastic pieces from splashing out and facilitating material feeding while preventing leakage.
