Description

Technical Field

[0001] This invention relates to the field of agricultural technology, and in particular to an impurity separator for recycling waste plastic film. Background Technology

[0002] With the large-scale application of agricultural mulch film, the "white pollution" generated after its disposal has become a serious problem restricting the sustainable development of agriculture. Residual mulch film damages the soil's topsoil structure, hinders the transport of water and nutrients, and affects crop emergence and growth. Therefore, effective recycling and clean treatment of waste mulch film in the field is a key link in achieving farmland environmental protection and resource recycling. Currently, common waste mulch film impurity separators mostly adopt vibrating screening, drum screening, or a combination of airflow cleaning techniques to separate mulch film fragments from adhering soil, roots, and other impurities. However, existing technologies and equipment generally have a fundamental flaw: in recycling operations, tangled and disordered rolls or large clumps of mulch film are usually directly fed into the separator without pretreatment. This "unseparated" feeding method makes it difficult for the mulch film clumps to be quickly broken up and fully spread within the machine; a large amount of mulch film is trapped inside, preventing the impurities trapped within from being exposed to screening or airflow. The direct consequence is that the separation process is incomplete, the effective working surface utilization rate is low, the single-machine processing efficiency is far from reaching the theoretical design level, and subsequent manual assistance in sorting or rework is often required. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention discloses an impurity separator for waste plastic film recycling, comprising an upper frame with supporting legs fixedly mounted on its lower side. The upper frame has multiple through holes, and a side plate with through grooves is fixedly mounted on one side. Rollers one and two are mounted on one side of the upper frame, and the plastic film passes between rollers one and two, splitting into multiple strands that pass through the through holes. A vibration assembly is mounted on the side plate to vibrate the plastic film. This technical solution pre-separates clumps of recycled plastic film into multiple strands, allowing them to be independently fed and vibrated through different channels, significantly improving the efficiency of impurity separation. This design effectively avoids the problem of plastic film entanglement and difficulty in exposing internal impurities during traditional whole-clump processing, preventing impurities from being trapped in the core of the plastic film clumps and unable to detach. After being processed into multiple strands, each strand of plastic film is fully stretched during vibration, making it easier for impurities such as soil and roots to detach from its surface and fall directly through specially designed holes, collecting in the collection device below. This makes the separation of impurities more thorough, the collection process continuous, and facilitates centralized processing.

[0004] Furthermore, the vibration assembly includes a horizontal plate, a central column fixedly mounted in the middle of the horizontal plate, a vibrator fixedly mounted on the central column, and the lower side of the central column inserted into a through hole for vibration.

[0005] Furthermore, two arc-shaped plates are installed on the outer side of the central column. The arc-shaped plates have a hollow structure and are closely arranged with mesh.

[0006] Furthermore, a contact rod is slidably mounted along the axial direction at the bottom of the central column, and a crossbar is fixedly mounted at the upper end of the contact rod. Two connecting rods are hinged to both sides of the central column, and the two connecting rods are hinged to the arc-shaped plate. A spring is fixedly mounted between the crossbar and the central column. Through the above technical solution, the grid structure in the hollow arc-shaped plate allows impurities to fall from the middle of the arc-shaped plate, and allows the arc-shaped plate to press against the mulch film and adhere tightly to the inner wall of the through hole, further improving separation efficiency due to vibration.

[0007] Furthermore, the side plate is provided with a slide rail, within which a sliding block one and a hinge wheel two are slidably mounted. Sliding block one and sliding block two are at the same height but staggered front to back. A connecting fork one is hinged to sliding block one, and a connecting fork two is hinged to sliding block two. A horizontal plate is hinged between sliding block two and sliding block two. Through this technical solution, the central column and the arc-shaped plate can rotate with connecting fork one into different through holes. Furthermore, the staggered arrangement of connecting forks one and two ensures that the central column always faces downwards, allowing for precise insertion into different through holes.

[0008] Furthermore, a screen is fixedly installed on the lower side of the upper frame, the screen has mesh openings, and multiple blocking strips are evenly arranged on the screen.

[0009] Furthermore, a support frame is fixedly installed on the lower side of the upper frame, and a cutting roller one and a cutting roller two are installed inside the support frame. The teeth of the cutting roller one and the cutting roller two are interlocked and located on the lower side of the screen. The mulch film is crushed by passing through the cutting roller one and the cutting roller two.

[0010] Furthermore, an installation strip is fixedly installed on the lower side of the support frame, and a fan is installed inside the installation strip. The installation strip is located below the second cutting roller. A lower plate is provided on one side of the support frame, and the fan blows the pulverized mulch film into the lower plate.

[0011] Furthermore, the support frame is equipped with a hinge wheel one and a hinge wheel two, which are arranged alternately, and the hinge wheel one is driven by a motor two.

[0012] Furthermore, a tripod is fixedly mounted on the lower plate, and vertical grids are fixedly mounted on the tripod. The vertical grids are located on one side of the second hinge wheel. Wedge block one and wedge block two are mounted on the support frame. Wedge block one and wedge block two guide the broken plastic film between hinge wheel one and hinge wheel two. Through the above technical solution, the initially separated material falls onto the screen, and the screen further filters out impurities. Subsequently, the remaining larger impurities and plastic film are crushed and refined by the relative rotation of cutting roller one and cutting roller two. The crushed mixture is blown by the airflow of the fan, with the lighter plastic film sheets being blown directionally towards the area of ​​hinge wheel one and hinge wheel two. Hinges wheel one and hinge wheel two rotate in opposite directions, forming a unidirectional conveying mechanism, ensuring that the broken plastic film can only move from the mounting strip side to the tripod side, effectively preventing backflow. As the plastic film moves through the vertical grid structure, it is lifted by airflow and mechanical action, while the remaining small amount of heavy impurities fall through the gaps in the grid into the tripod below, thus achieving the final fine separation and classification collection of the plastic film and impurities.

[0013] The advantages of this invention compared to the prior art are: (1) Through the technical solution of the present invention, the clumps of recycled plastic film are pre-divided into multiple strands, independently fed into each other, and vibrated through different channels, which can significantly improve the efficiency of impurity separation. This design effectively avoids the problem of plastic film entanglement and wrapping and internal impurities being difficult to expose when processing in whole clumps in the traditional method, and prevents impurities from being stuck in the core of the plastic film clumps and unable to fall off. After being processed into strands, each plastic film is fully stretched during vibration, and its surface and impurities such as soil and roots are more easily detached under the action of vibration, and fall directly through specially designed through holes, collecting in the collection device below, making the impurity separation more thorough, the collection process continuous, and convenient for centralized processing.

[0014] (2) Through the technical solution of the present invention, the arc plate adopts a hollow structure and is set with a grid. This design realizes a dual optimization function: on the one hand, the grid allows the fine impurities that have not been completely separated to fall directly from the middle of the arc plate during the vibration process, reducing the retention of impurities in the equipment; on the other hand, the solid frame of the arc plate can firmly press the mulch film against the inner wall of the through hole during the movement, increasing the contact area and pressure between the two, so that the vibration energy can be transmitted to the mulch film more efficiently, promoting its shaking and impurity peeling, thereby improving the overall separation efficiency and cleanliness at the structural level.

[0015] (3) Through the technical solution of the present invention, the central column and its connected arc plate can follow the rotation of the connecting fork one as a whole, flexibly switch and accurately enter different through holes to adapt to the alternating or synchronous processing requirements of multiple strands of mulch film. In particular, by staggering the connecting fork one and connecting fork two in structure, it can be ensured that the central column always maintains a stable vertical downward posture during the rotation and repositioning process, so that it can be accurately and smoothly inserted into the target through hole after each shift, avoiding jamming or alignment deviation, and ensuring the continuity and reliability of the strand vibration process.

[0016] (4) Through the technical solution of the present invention, the initially separated material falls onto the screen, which further filters and removes impurities; subsequently, the remaining larger impurities and plastic film are crushed and refined by the relative rotation of cutting roller one and cutting roller two. The crushed mixture is blown by the airflow of the fan, in which the lighter plastic film is blown directionally towards the area of ​​hinge roller one and hinge roller two. Hinges roller one and hinge roller two rotate in opposite directions, forming a unidirectional conveying mechanism, ensuring that the crushed plastic film can only move from the side of the mounting strip to the side of the tripod, effectively preventing backflow. When the plastic film passes through the vertical grid structure during movement, it is lifted by the airflow and mechanical action, while the remaining small amount of heavy impurities fall into the tripod below through the grid gaps, thereby achieving the final fine separation and classification collection of plastic film and impurities.

Detailed Implementation

[0026] To gain a better understanding of the technical solution and beneficial effects of the present invention, the technical solution of the present invention and its beneficial effects are described in detail below with reference to the accompanying drawings.

[0027] like Figures 1-8 As shown, a waste plastic film recycling impurity separator includes a support frame 3. A lower plate 6 is fixedly installed on the first side of the support frame 3. The second side of the support frame 3 is inclined upward and an upper frame 19 is fixedly installed on the upper side. Two side plates 20 are fixedly installed at the upper end of the upper frame 19, and a vibration component is fixedly installed between the two side plates 20.

[0028] In this embodiment, a motor 11 is fixedly mounted on one side of the upper frame 19. Rollers 12 and 23 are rotatably mounted on the upper frame 19, with a relatively close distance between them. The mulch film passes between rollers 12 and 23. A gear 4 18 is fixedly mounted on roller 12, and a gear 3 17 is fixedly mounted on roller 23. Gears 3 17 and 4 18 mesh. The motor 11 drives roller 2 13, which in turn drives gears 3 17 and 4 18, ultimately causing rollers 12 and 2 13 to rotate together. The rollers 12 and 13, made of rubber, are used to push the plastic film upwards, providing a tight compression without damaging it. A groove 22 is located on the underside of the side plate 20. After passing through rollers 12 and 13, the plastic film passes through the groove 22 and finally enters the through-hole 23, located on the upper shelf 19. Multiple through-holes 23 are provided, allowing the plastic film to be divided into multiple strands and fed into them independently. Pre-dividing the clumps of recycled plastic film into multiple strands and feeding them independently through different channels significantly improves the efficiency of impurity separation. This design effectively avoids the problems of plastic film tangling and wrapping, making it difficult to expose internal impurities during traditional whole-clump processing, and prevents impurities from getting stuck in the core of the plastic film clumps and unable to detach. After being processed into multiple strands, each strand of plastic film is fully stretched during vibration, making it easier for impurities such as soil and roots to detach from its surface and fall directly through specially designed holes, collecting in the collection device below. This makes the separation of impurities more thorough, the collection process continuous, and facilitates centralized processing.

[0029] In this embodiment, a screen 30 is fixedly installed inside the inclined portion of the support frame 3. Baffle strips 31 are evenly fixedly installed on the screen 30. Impurities shaken down fall onto the screen 30 through the through-holes 23 and then fall. The baffle strips 31 prevent impurities from flowing down the screen 30. A material box 2 is installed directly below the screen 30, and a handle 14 is provided on the outside of the material box 2. Impurities falling from the screen 30 fall into the material box 2. Cutting roller 1 24 and cutting roller 25 are rotatably mounted inside the support frame 3. Gear 9 is fixedly mounted on the first cutting roller 24, and gear 10 is fixedly mounted on the second cutting roller 25. Gear 9 and gear 10 mesh. Motor 3 16 is fixedly mounted on one side of the support frame 3. Motor 3 16 drives the first cutting roller 24 to rotate. After the mulch passes through the through hole 23, it is crushed between the first cutting roller 24 and the second cutting roller 25. The first cutting roller 24 and the second cutting roller 25 are located below the screen 30, but not directly below it. They are obliquely below the screen 30 along its inclined direction. The crushed mulch falls into the support frame 3.

[0030] In this embodiment, a mounting strip 33 is fixedly installed at the bottom of the support frame 3, and multiple fans 32 are fixedly installed on the mounting strip 33. The mounting strip 33 is located directly below the cutting roller 25. A connecting fork 36 and a sliding block 37 are rotatably mounted inside the support frame 3. The connecting fork 36 and the sliding block 37 are without blades. Wedge blocks 28 and 29 are fixedly installed on the upper and lower parts of the support frame 3. The gap between wedge blocks 28 and 29 corresponds to the position between hinge wheel 26 and hinge wheel 27. When the fans 32 are activated, they blow the falling pulverized plastic film. The pulverized plastic film passes through the wedge blocks 28 and 29. The guide clip 29 is located between hinge wheel 1 26 and hinge wheel 27. Motor 2 15 is fixedly installed on one side of support frame 3. Motor 2 15 drives hinge wheel 1 26 to rotate. The plastic film attached between hinge wheel 1 26 and hinge wheel 27 rotates and enters the lower plate 6. Because of the air blown by fan 32, the plastic film fragments in the lower plate 6 may return to support frame 3. However, the directional rotation of hinge wheel 1 26 and hinge wheel 2 27 allows the broken plastic film to pass between hinge wheel 1 26 and hinge wheel 2 27 without moving in any direction. Wedge block 1 28 and wedge block 2 29 guide the plastic film between hinge wheel 1 26 and hinge wheel 27.

[0031] In this embodiment, a tripod 5 is fixedly mounted on the lower plate 6. The tripod 5 has a hollow interior, and one side of the tripod 5 is provided with vertical grids 4. The lower side of the vertical grids 4 is a completely sealed plate, and the upper side is a grid, which is inclined. After passing through the first hinge wheel 26 and the second hinge wheel 27, the mulch film passes through the vertical grids 4 and tilts upwards, finally falling to one side of the lower plate 6. During the process, impurities carried along the mulch film fall into the tripod 5 as it climbs along the vertical grids 4. The lower plate 6 is sealed with an upper plate 7 and a bending plate 8, and the fan 32 has a small airflow, just enough to blow the broken mulch film. The initially separated material falls onto a screen, which further filters out impurities. Subsequently, the remaining larger impurities and mulch film are crushed and refined by the relative rotation of the first cutting roller and the second cutting roller. The crushed mixture is blown by the fan airflow, with the lighter mulch film sheets being blown directionally towards the area of ​​the first and second hinge wheels. Hinge wheel one and hinge wheel two rotate in opposite directions, forming a unidirectional conveying mechanism. This ensures that the broken plastic film can only move from the installation strip side to the tripod side, effectively preventing backflow. As the plastic film moves through the vertical grid structure, it is lifted by airflow and mechanical action, while the remaining small amount of heavy impurities fall through the grid gaps into the tripod below, thus achieving the final fine separation and classification collection of the plastic film and impurities.

[0032] In this embodiment, a slide rail 21 is provided on the side plate 20, and a vibration component is slidably mounted on the slide rail 21. The vibration component includes a sliding block 34 and a hinge wheel 27. The sliding block 34 and the sliding block 27 are slidably mounted in the slide rail 21. The sliding block 34 and the sliding block 27 are at the same height and are offset from front to back (front to back refers to the direction of movement of the vibration component). A connecting fork 36 is hinged to the sliding block 34, and a motor 35 is fixedly mounted on the sliding block 34. The motor 35 drives the connecting fork 36 to rotate. A device is mounted on the sliding block 27. There is a connecting fork 2 38. Connecting fork 1 36 and connecting fork 2 38 are identical parts. Taking connecting fork 1 36 as an example, connecting fork 1 36 has a three-pronged structure, with a horizontal plate 39 hinged to each fork. The horizontal plate 39 has two hinge holes, which are respectively hinged to connecting fork 1 36 and connecting fork 2 38. The center distance between the two hinge holes is the same as the distance between sliding block 1 34 and sliding block 2 37. In this way, when motor 4 35 drives connecting fork 1 36 to rotate, the misalignment of connecting fork 2 38 ensures that the horizontal plate 39 remains horizontal. The central column and its connected arc plate can follow the rotation of connecting fork 1 as a whole, flexibly switching and precisely entering different through holes to adapt to the needs of alternating or synchronous processing of multiple strands of mulch film. In particular, by structurally staggering the connection fork one and the connection fork two, it is possible to ensure that the central column always maintains a stable vertical downward posture during the rotation and repositioning process. This ensures that it can be accurately and smoothly inserted into the target through hole after each repositioning, avoiding jamming or alignment deviation, and guaranteeing the continuity and reliability of the strand vibration process.

[0033] In this embodiment, a central column 40 is fixedly installed at the center of the horizontal plate 39. A vibrator 41 is fixedly installed on the upper side of the central column 40. The lower end of the central column 40 is hollowed out, and a contact rod 44 is slidably installed inside. A horizontal bar 45 is fixedly installed on the upper part of the contact rod 44, and a spring 46 is fixedly installed on the upper side of the horizontal bar 45. The spring 46 is fixedly connected to the central column 40. Two connecting rods 43 are hinged to both sides of the central column 40. An arc-shaped plate 42 is hinged to the connecting rod 43. A connecting ear 47 is fixedly installed inside the arc-shaped plate 42. The connecting ear 47 is hinged to the two connecting rods 43. The lower connecting rod 43 is attached to the horizontal bar 45. The arc-shaped plate 42 has a hollow structure and is uniformly set in a mesh shape on the outside. The arc-shaped plate 42 presses the mulch film into the through hole 23 and then vibrates. Impurities on the mulch film fall off through the mesh and hollow structure of the arc-shaped plate 42. The curved plate adopts a hollow structure and is equipped with a grid. This design achieves a dual optimization function: on the one hand, the grid allows fine impurities that have not been completely separated to fall directly from the middle of the curved plate during vibration, reducing the retention of impurities in the equipment; on the other hand, the solid frame of the curved plate can firmly press the mulch film against the inner wall of the through hole during movement, increasing the contact area and pressure between the two, so that the vibration energy can be transferred to the mulch film more efficiently, promoting its shaking and impurity removal, thereby synergistically improving the overall separation efficiency and cleanliness at the structural level.

[0034] Working principle: The waste plastic film is placed on the upper shelf 19 between roller 12 and roller 13. It is better if the plastic film can be divided into multiple strands. The strands are placed in the through hole 23. Then, motor 4 35 is started. Motor 4 35 drives connecting fork 1 36 to rotate. The rotating connecting fork 1 36 drives horizontal plate 39 and central column 40. The central column 40 will be inserted into the through hole 23, and the plastic film will be inserted into the through hole 23. The contact rod 44 on the lower side of the central column 40 pushes the plastic film downward. At this time, the contact rod 44 is squeezed by force, which will compress spring 46. At the same time, the horizontal bar 45 is pushed upward by the connecting rod 43. This causes the arc plate 42 to expand outward, squeezing the mulch film inside the through hole 23. Then, the vibrator 41 is activated to vibrate. After vibration, impurities on the mulch film squeezed by the arc plate 42 fall off. Because the arc plate 42 has a mesh structure and is hollow, the impurities fall from inside the arc plate 42, landing on the screen 30 and leaking into the material box 2 for collection. Then, the motor 45 continues to drive the connecting fork 36 to rotate, and the other center columns 40 will be inserted into other through holes 23. At this time, the position of the center column 40 in the through hole 23 will change, moving up and down and left and right simultaneously. When it moves left and right, the connecting rod 43 is squeezed inside the through hole 23. Rod 43 presses against the crossbar 45, pushing the contact rod 44 downwards to prevent jamming or damage to parts. This process is repeated to vibrate the plastic film in each through hole 23. Then, the machine stops and the plastic film is threaded between cutting roller 1 24 and cutting roller 25. Cutting roller 1 24 and cutting roller 25 exert a pulling force while crushing the film, pulling it downwards. If the film breaks during operation, it is continuously squeezed downwards by the vibration assembly to fill the upper side of the screen 30, and then squeezed between cutting roller 1 24 and cutting roller 25, where it is further crushed. The crushed film falls onto the support frame 3, and the fan is activated. Fan 32 blows the pulverized plastic film, which is guided by wedge block 28 and wedge block 29 and blown between hinge wheel 26 and hinge wheel 27, where it gets stuck. Then, motor 215 is started to drive hinge wheel 26, which sends the plastic film stuck between hinge wheel 26 and hinge wheel 27 to the lower plate 6. Then, under the action of fan 32, it falls onto the vertical grid 4, and finally falls onto one side of the tripod 5. During the process, impurities mixed in with the broken plastic film will fall into the tripod 5. The vertical grid 4 acts as a filter, preventing the plastic film from entering the tripod 5, while the impurities do enter the tripod 5, thus achieving separation.
