Description

Technical Field

[0001] The present invention relates to the technical field of plastic film recycling, and specifically to a plastic film recycling device. Background Art

[0002] With the large-scale application of plastic films in fields such as packaging, agriculture, and industry, the problem of recycling and treating their waste has attracted increasing attention. Due to their lightweight and durable characteristics, plastic films are difficult to degrade naturally. If randomly discarded or piled up, they will cause serious "white pollution" to the environment. Therefore, developing an efficient plastic film recycling device to achieve the recycling of resources has important environmental and economic significance.

[0003] However, the existing plastic film recycling devices have many deficiencies. For example, in the crushing process of traditional recycling devices, plastic films are prone to winding around the crushing components, resulting in uneven crushing and affecting the quality of recycled products. In addition, the separation of crushed plastic films from impurities is not thorough, which easily causes difficulties in subsequent processing.

[0004] In the separation link, most of the existing recycling devices adopt simple screening methods, which are difficult to effectively separate fine impurities in plastic films, and blockages are prone to occur during the separation process, affecting the recycling efficiency.

[0005] In summary, the existing plastic film recycling devices have obvious deficiencies in crushing efficiency and impurity separation effect, and are difficult to meet the requirements of large-scale industrial recycling. Therefore, developing a plastic film recycling device that can efficiently crush, thoroughly separate impurities, and has an automatic cleaning function has important practical significance.

[0068] Support 4, connected to the bottom of the recycling bin 1, providing support;

[0069] Screen 5, arranged inside the recycling bin 1, below the crushing component 3, for separating solid impurities in the plastic film;

[0070] Separation mechanism 6, arranged below the screen 5, for assisting the screen 5 to separate solid impurities in the plastic film;

[0071] Cleaning mechanism 7, arranged on the screen 5, for cleaning the screen 5;

[0072] Among them, the sieve mesh 5 includes:

[0073] A ventilation plate 52, fixedly connected to the inner wall of the recycling box 1;

[0074] A sieve plate 53, hinged to the ventilation plate 52 on one side and deflecting around the hinge;

[0075] The cleaning mechanism 7 includes:

[0076] A plurality of arc-shaped cleaning plates 71, movably connected to the inner wall of the recycling box 1 for cleaning the sieve plate 53;

[0077] A plurality of limiting rods 72, fixedly connected to the inner wall of the recycling box 1 and in contact with the bottom of the arc-shaped cleaning plate 71, for limiting the deformation of the arc-shaped cleaning plate 71 and cleaning the bottom of the sieve plate 53.

[0078] The cleaning mechanism 7 further includes:

[0079] A conical push block 73, fixedly connected to the arc-shaped inner wall of the arc-shaped cleaning plate 71;

[0080] A cleaning component 74, arranged on the sieve plate 53 for cleaning the blockage in the through holes of the sieve plate 53;

[0081] The sieve mesh 5 further includes:

[0082] A blanking inclined plate 51, fixedly connected to the inner wall of the recycling box 1, and the inclined end is connected to the top of the ventilation plate 52;

[0083] A rectangular through hole is provided on the right side wall of the recycling box 1, and the lower right side of the sieve plate 53 abuts against the rectangular through hole.

[0084] The cleaning component 74 includes:

[0085] A fixed block 741, fixedly connected to the movable cavity opened in the sieve plate 53;

[0086] A movable block 742, arranged in the movable cavity and moving in the movable cavity. Every two movable blocks 742 move towards the through hole to squeeze the blockage in the through hole;

[0087] A second elastic telescopic rod 743, arranged in the movable block 742 and the fixed block 741 for resetting the movable block 742;

[0088] A limiting plate 744, fixedly connected to one end of the elastic telescopic rod 743, and the limiting plate 744 is in contact with the conical push block 73 for pushing the limiting plate 744 to move.

[0089] Working principle: After the plastic film is crushed, the plastic film will fall onto the screen 5 through the crushing component and be separated. The separation is carried out through the sieve plate 53 on the screen 5. At this time, the impurities will fall below the recycling box 1 through the sieve plate 53, while the plastic film will pass through the sieve plate 53 and discharge to the right discharge hopper 2, thus achieving the purpose of separating the impurities in the plastic film.

[0090] At the same time, during the up and down movement of the sieve plate 53, it will squeeze the arc-shaped cleaning plate 71, thereby generating a force on the arc-shaped cleaning plate 71 and being limited by the limiting rod 72 to produce a limiting effect on it. At this time, the arc-shaped cleaning plate 71 will be compressed and expanded, so as to scrape off the impurities attached to the bottom of the sieve plate 53 to improve the cleaning effect. At the same time, when the arc-shaped cleaning plate 71 is compressed and expanded, in cooperation with the downward moving sieve plate 53, the conical push block 73 moves relatively upward at this time, thereby squeezing the fixed block 741. By squeezing the fixed block 741, the second elastic telescopic rod 743 is pushed, and then the movable block 742 is pushed to move. The two movable blocks 742 move relatively, reducing the size of the through holes on the sieve plate 53 to break the impurities stuck inside and avoid blockage, ensuring smooth separation.

[0091] Please refer to Figures 1-9 , on the basis of the above embodiment, in another embodiment of the present invention, the crushing component 3 includes:

[0092] Two crushing shafts 31 are respectively rotatably connected to the inner wall of the recycling box 1, and the back of the crushing shaft 31 movably penetrates through the recycling box 1 and extends backward;

[0097] The scraping component 36 includes:

[0098] A plurality of scraping plates 361 are fixedly connected to the inner wall of the recycling box 1 and are arranged at the intervals of the crushing teeth 33;

[0099] The movable scraping plate 362 is rotatably connected to the installation groove of the scraping plate 361;

[0100] The elastic piece 363 is fixedly connected in the installation groove of the scraping plate 361 and abuts against the movable scraping plate 362, and is used to push the movable scraping plate 362 to deflect around the rotation point and abut against the outer wall of the crushing tooth 33, so as to clean the impurities attached to the outer wall of the crushing tooth 33 for assistance.

[0101] Working principle: By starting the first motor 35, at this time, the first motor 35 drives the two crushing shafts 31 to rotate towards each other through the first gearbox 34 at the same time, so as to synchronously drive the crushing cylinder 32 and the crushing teeth 33 to rotate towards each other, and then the plastic film placed in the recycling box 1 can be crushed.

[0102] When the crushing teeth 33 rotate relative to the scraping assembly 36, the scraping assembly 36 can clean the impurities attached to the outer wall of the crushing teeth 33 and the outer wall of the crushing cylinder 32, so as to avoid affecting the purpose of crushing the plastic film. At the same time, when the crushing teeth 33 rotate, the elastic piece 363 will abut against the movable scraping plate 362 to abut against the crushing teeth 33 and deflect around the hinge point of the movable scraping plate 362, thereby improving the cleaning effect.

[0112] Working principle: While the second motor is working, and by the action of the second gearbox, the blade 64 is driven to rotate rapidly. At this time, it blows to the right through the air-permeable plate 52. At this time, the impurities and plastic films that fall after being crushed can be blown, so that the lighter plastic films can be blown to the right, while the heavier impurities fall onto the lower part of the recycling box 1 through the sieve plate 53 for recycling. At the same time, through the transmission of the second gearbox, the rotation speed is reduced to drive the rotating rod 65 to rotate. At this time, the elliptical wheel 66 can be rotated synchronously, and then the arc-shaped block 67 is pushed to drive the sieve plate 53 to move upward, and under the action of gravity, the purpose of shaking the sieve plate 53 is achieved, improving the separation effect.
