[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Reference Figure 1-Figure 8As shown, the present invention provides a plastic film processing waste recycling device, comprising a recycling box 1, a feeding port 11 is opened at the top of the recycling box 1, and the recycling box 1 comprises a primary crushing mechanism 2 for primary crushing, a cleaning mechanism 3 for preventing winding, a secondary crushing mechanism 4 for secondary crushing, a blower mechanism 5 for providing airflow, and an extrusion mechanism 8 for extrusion molding;

[0037] A double-shaft motor 42 is provided on one side of the recycling box 1, and a main gear 43 is fixedly sleeved on the output shaft at one end of the double-shaft motor 42, and a plurality of driven gears 44 are meshed and installed on the outer surface of the main gear 43, and a crushing shaft 45 is fixedly sleeved inside the main gear 43 and the driven gear 44, and one end of the crushing shaft 45 passes through the side wall of the recycling box 1 and extends to the inside, and the crushing shaft 45 is rotatably connected to the middle part of the inner wall of the recycling box 1, and a plurality of cutters 46 are fixedly connected to the outer surface of the crushing shaft 45, and the plurality of cutters 46 are arranged equidistantly.

[0038] In this embodiment, the waste is firstly crushed by the primary crushing mechanism 2, and then the double-axis motor 42 is started, and the output shaft at one end drives the main gear 43 to start rotating. The main gear 43 drives several driven gears 44 to rotate synchronously through meshing transmission. When the main gear 43 and several driven gears 44 rotate, the crushing shaft 45 will rotate accordingly. As the crushing shaft 45 rotates, several cutters 46 on its outer surface start to rotate at high speed, further crushing the waste into smaller shapes. The multi-stage crushing method can realize the gradual refinement of the waste, improve the uniformity and fineness of the crushing, and improve the quality of the recycled products.

[0039] In a further embodiment, the output shaft at the other end of the dual-axis motor 42 is fixedly sleeved with the transmission shaft of the suction fan 51, and the suction fan 51 is fixedly installed on the top of the second mounting base 41. The output end of the suction fan 51 is fixedly sleeved with a diversion pipe 52, and the outlets at both ends of the diversion pipe 52 are fixedly sleeved with an air outlet pipe 53. One end of the air outlet pipe 53 passes through the side wall of the recovery box 1 and extends to the interior. A plurality of nozzles 54 are threadedly connected to the inner side of the air outlet pipe 53, and the nozzles 54 are arranged downward at a 30-degree inclination.

[0040] In this embodiment, while the dual-axis motor 42 provides power for the secondary crushing mechanism 4, the output shaft at the other end drives the suction fan 51 to work, and the outside air is transported to the inside of the air outlet pipe 53 through the diversion pipe 52. Finally, the airflow ejected from the nozzle 54 can further disperse the waste after the preliminary crushing, ensuring that the secondary crushing operation can more fully cut and crush each piece of waste, thereby improving the uniformity of the crushing effect. At the same time, the airflow can promote the waste to move more smoothly, reducing the residence time of the waste in the equipment and improving the working efficiency of the entire recycling device.

[0041] In a further embodiment, a crushing motor 22 is provided on the other side of the recycling box 1, and a small pulley 23 is fixedly sleeved on the output shaft of the crushing motor 22, and a belt 24 is meshed and installed on the outer surface of the small pulley 23, and a large pulley 25 is meshed and installed on the top of the belt 24, and a first crushing roller 26 transmission shaft is fixedly sleeved inside the large pulley 25, and the first crushing roller 26 is rotatably connected to the upper inner wall of the recycling box 1, and the transmission shaft at one end of the first crushing roller 26 passes through the side wall of the recycling box 1 and is fixedly sleeved with a first toothed disc 27, and a second toothed disc 28 is meshed and installed on the outer surface of the first toothed disc 27, and a second crushing roller 29 transmission shaft is fixedly sleeved inside the second toothed disc 28, and the second crushing roller 29 is rotatably connected to the upper inner wall of the recycling box 1, and the crushing teeth of the first crushing roller 26 are engaged in the notch between adjacent crushing teeth of the second crushing roller 29.

[0042] In this embodiment, firstly, the waste is put into the recycling box 1 through the feed port 11, and then the crushing motor 22 is started, and its output shaft drives the small pulley 23 to rotate, and the small pulley 23 drives the large pulley 25 to rotate through the belt 24. When the large pulley 25 rotates, it will drive the transmission shaft of the first crushing roller 26 to rotate, so that the first crushing roller 26 rotates on the upper part of the inner wall of the recycling box 1. When the first crushing roller 26 rotates, the first toothed disc 27 also rotates, and the first toothed disc 27 drives the second toothed disc 28 to rotate synchronously, so that the second crushing roller 29 is also driven by the second toothed disc 28 to rotate on the upper part of the inner wall of the recycling box 1. In addition, during the rotation of the first crushing roller 26 and the second crushing roller 29, the crushing teeth of the two are mutually engaged in the notches between the adjacent crushing teeth of each other, so as to achieve the purpose of crushing operations such as extrusion and shearing on the waste, and can more comprehensively process plastic film processing waste of different shapes and sizes, effectively improving the effect and efficiency of the initial crushing.

[0043] In a further embodiment, a pinion 31 is meshed and installed on one side of the bottom end of the first toothed disc 27 and the second toothed disc 28, and a cleaning shaft 32 is fixedly sleeved inside the pinion 31. One end of the cleaning shaft 32 passes through the side wall of the recycling box 1 and extends to the inside. The cleaning shaft 32 is rotatably connected to the inner wall of the recycling box 1. A plurality of scraping blocks 33 are fixedly connected to the outer surface of the cleaning shaft 32. One end of the scraping block 33 below the first crushing roller 26 is embedded in the notch between adjacent crushing teeth of the first crushing roller 26, and the scraping block 33 below the second crushing roller 29 is embedded in the notch between adjacent crushing teeth of the second crushing roller 29.

[0044] In this embodiment, when the first toothed disc 27 and the second toothed disc 28 rotate, the pinion 31 on one side of the bottom end thereof will rotate accordingly, and the pinion 31 will drive the cleaning shaft 32 to rotate. When the cleaning shaft 32 rotates, it will drive the scraper block 33 on its outer surface to rotate together. At this time, the rotating scraper block 33 can promptly scrape off the waste material remaining in the groove between the crushing teeth, thereby keeping the space between the crushing teeth clean, ensuring that the crushing roller can continuously and efficiently perform the crushing work, ensuring the normal operation of the equipment, reducing the downtime for maintenance, and improving the working efficiency and reliability of the device.

[0045] In a further embodiment, a material guide plate 6 is fixedly connected to the middle of the inner wall of the recycling box 1, an extrusion cylinder 7 is fixedly connected to the bottom end of the groove of the material guide plate 6, the bottom end of the extrusion cylinder 7 is fixedly connected to the bottom wall of the recycling box 1, and the extrusion cylinder 7 is connected to the outside of the bottom wall of the recycling box 1.

[0046] In this embodiment, after the waste has undergone a series of crushing processes, the guide plate 6 guides the waste to flow downward, so that the waste can be more concentrated at the location of the extrusion cylinder 7, further improving the accuracy of the material guidance and preparing for subsequent extrusion molding operations.

[0047] In a further embodiment, a third mounting seat 81 is fixedly connected to one side of the lower inner wall of the recovery box 1, a first cylinder 82 is fixedly installed on the top of the third mounting seat 81, a connecting block 83 is fixedly sleeved on the telescopic shaft of the first cylinder 82, one end of the connecting block 83 passes through a groove on one side of the extrusion cylinder 7 and is fixedly connected to a material baffle plate 84, and the material baffle plate 84 is slidably connected to the inner wall of the extrusion cylinder 7.

[0048] In this embodiment, when the extrusion cylinder 7 reaches a suitable amount to meet the extrusion requirements, the first cylinder 82 is started, and its telescopic shaft contracts, pushing the baffle plate 84 to move into the extrusion cylinder 7 through the connecting block 83, thereby separating the upper and lower parts of the extrusion cylinder 7, preventing more waste from continuing to enter the extrusion area, so that the waste will only accumulate in the upper part of the extrusion cylinder 7, thereby ensuring the stability of the extrusion process and the quality and consistency of the extruded products.

[0049] In a further embodiment, a second cylinder 85 is fixedly installed on one side of the bottom wall of the recovery box 1, and the telescopic shaft of the second cylinder 85 passes through the other side wall of the extrusion cylinder 7 and is fixedly sleeved with an extrusion plate 86, which is slidably connected to the inner wall of the extrusion cylinder 7.

[0050] In this embodiment, after the baffle plate 84 separates the upper and lower parts of the extrusion cylinder 7, the second cylinder 85 is started, and its telescopic shaft will push the extrusion plate 86 to move along the inner wall of the extrusion cylinder 7, so that the waste is gradually extruded into a shape that meets the requirements of recycling in the relatively closed space of the extrusion cylinder 7, thereby achieving the purpose of extrusion molding, improving the efficiency of extrusion molding, and reducing production time and energy consumption.

[0051] In a further embodiment, a handle 87 is provided on the front side of the recycling box 1, and a connecting rod 88 is fixedly connected to the rear side of the handle 87, and the connecting rod 88 is slidably connected to the bottom wall of the recycling box 1.

[0052] In this embodiment, after the waste material completes the extrusion molding process, the operator holds the handle 87 and pulls it outward. The handle 87 drives the discharge plate 89 to move synchronously through the connecting rod 88. When the discharge plate 89 moves outward, the channel at the bottom end of the extrusion cylinder 7 will gradually open, so that the waste material after extrusion molding can smoothly flow out from the bottom end of the extrusion cylinder 7 through the opening formed between the discharge plate 89 and the groove at the bottom end of the extrusion cylinder 7, thereby realizing the smooth discharge of the waste material after extrusion molding, without the need for complicated tools or cumbersome operating steps, thereby improving work efficiency and reducing the labor intensity of the operator.

[0053] In a further embodiment, a second mounting seat 41 is fixedly connected to one side of the recycling box 1, and a dual-axis motor 42 is fixedly installed on the top of the second mounting seat 41. The other side of the recycling box 1 is fixedly connected to the first mounting seat 21, and a crushing motor 22 is fixedly installed on the top of the first mounting seat 21.

[0054] In this embodiment, the main function of the first mounting seat 21 and the second mounting seat 41 is to provide a stable mounting base for the motor, which can ensure that the motor will not shift or shake due to its own vibration or external interference during operation, thereby ensuring that the motor can output power stably and maintain the normal operation of the entire recovery device.
