[0018] 2. In the present invention, the driving shaft rotates to drive the first bevel gear to rotate, so that the second bevel gear meshing with it rotates, so that the rotating rod and the second rotating disk rotate. The rotation of the second rotating disk drives the second eccentric rod in the eccentric position to rotate, and then drives the connecting rod to swing back and forth, pulling the fixed rod and the connecting frame to swing back and forth, and then drives the slide plate to swing back and forth under the limiting action of the guide sleeve. Since the driving shaft and the driven shaft rotate in opposite directions, the reciprocating sliding directions of the two slide plates are opposite, that is, when one of the slide plates slides backward, the other slides forward, so that the plastic fragments and film fragments accumulated on the upper sides of the two slide plates can be shaken and discharged, so that the plastic fragments and film fragments are discharged more evenly, which is convenient for the subsequent blowing out of the film fragments from the plastic fragments, thereby improving the separation effect.

[0019] 3. In the present invention, the first turntable is driven to rotate by the rotation of the driving shaft, so that the first eccentric rod at the eccentric position of the first turntable rotates, and then drives the transmission component to swing back and forth up and down, thereby pulling the connecting bracket to lift up and down, and driving the sealing lifting plate at the bottom of the inner side of the cleaning cylinder to slide back and forth up and down. Since the bottom of the cleaning cylinder is sealed and a water spray hole is provided on the sealing lifting plate, when the sealing lifting plate slides down, the clean water on the lower side of the sealing lifting plate will be squeezed and sprayed out from the water spray hole. Since the crushed plastic fragments are accumulated on the upper side of the sealing lifting plate, the sprayed clean water will impact the plastic fragments, which on the one hand cleans the impurities on the surface of the plastic fragments, and on the other hand disturbs the plastic fragments and the clean water, so that the plastic fragments contact with the stirring mechanism, and further improves the cleaning effect and efficiency of the plastic fragments.

[0039] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0040] Example 1: Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, a plastic recycling device includes a first crushing cylinder 1 and a second crushing cylinder 2. The middle parts of the first crushing cylinder 1 and the second crushing cylinder 2 are connected to each other. A feed hopper 3 is fixedly connected above the connecting part between the first crushing cylinder 1 and the second crushing cylinder 2. The feed hopper 3 adopts a funnel structure with a large top and a small bottom, which is convenient for pouring plastic bottles into the first crushing cylinder 1 and the second crushing cylinder 2. A separation cylinder 4 is fixedly connected below the connecting part between the first crushing cylinder 1 and the second crushing cylinder 2. Support frames 7 are fixedly arranged on both sides of the separation cylinder 4. The support frames 7 are used to support and fix the plastic recycling device. The inner sides of the first crushing cylinder 1 and the second crushing cylinder 2 A pulverizing assembly 24 is provided which rotates in opposite directions. The pulverizing assembly 24 includes pulverizing rollers 2401 which are rotatably arranged inside the first pulverizing cylinder 1 and the second pulverizing cylinder 2. A plurality of pulverizing blades 2402 are equidistantly arranged on the outer sides of the two pulverizing rollers 2401. A pulverizing motor 13 is fixedly arranged on the rear side of the second pulverizing cylinder 2. A driving shaft 19 which rotates and passes through the second pulverizing cylinder 2 and is fixedly connected to the pulverizing roller 2401 therein is fixedly arranged on the output end of the pulverizing motor 13. A driven shaft 16 which rotates and passes through the inner side of the first pulverizing cylinder 1 and is fixedly connected to the other pulverizing roller 2401 is fixedly arranged on one end of the driving shaft 19. A driving gear 14 is arranged on the outside of the second crushing cylinder 2, and a driven gear 15 fixedly connected to the driven shaft 16 is meshed on one side of the driving gear 14. When in use, the driving shaft 19 is driven to rotate by the crushing motor 13, so that the crushing roller 2401 on the driving shaft 19 rotates on the inside of the second crushing cylinder 2, so that the crushing roller 2401 and the crushing blade 2402 on the inside of the second crushing cylinder 2 rotate from top to bottom toward the connecting part. At the same time, the rotation of the driving shaft 19 will drive the driving gear 14 thereon to rotate, and then drive the driven gear 15 to rotate in the opposite direction, and then drive the driven shaft 16 to rotate. The crushing roller 2401 on the driven shaft 16 rotates in the opposite direction inside the first crushing cylinder 1, and the crushing roller 2401 and the crushing blade 2402 inside the first crushing cylinder 1 rotate from top to bottom toward the connecting part, that is, the crushing roller 2401 and the crushing blade 2402 inside the first crushing cylinder 1 and the crushing roller 2401 and the crushing blade 2402 inside the second crushing cylinder 2 rotate in the opposite direction together, and at the same time rotate from top to bottom toward the connecting part, so that the plastic bottles poured into the first crushing cylinder 1 and the second crushing cylinder 2 can be crushed, thereby improving the crushing effect.

[0041] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig.10 , Fig.12 , Fig.13 , Fig.14 , Fig.16 As shown, guide sleeves 23 are fixedly provided on both sides of the inner upper part of the separation cylinder 4, and slide plates 22 that can slide forward and backward are provided on the sides of the two guide sleeves 23 that are close to each other. A gap is formed between the two slide plates 22, and the crushed plastic fragments and film fragments can be evenly discharged through the gap. A transmission mechanism 10 that simultaneously drives the two slide plates 22 to slide in opposite directions is provided on the outer side of the separation cylinder 4. The transmission mechanism 10 includes a first bevel gear 1001 that is fixedly sleeved on the driving shaft 19 and the driven shaft 16 respectively, and the lower side of the first bevel gear 1001 is meshed with a first bevel gear 1001. The second bevel gear 1002 is provided with a rotating rod 1003 fixedly disposed on the lower side of the second bevel gear 1002, and a limit bearing 1004 fixedly connected to the outer side of the second crushing cylinder 2 is provided in the middle of the rotating rod 1003, and a second rotating disk 1005 is fixedly disposed on the lower end of the rotating rod 1003, and a second eccentric rod 1006 is fixedly disposed at the eccentric position of the second rotating disk 1005, and a connecting rod 1007 is provided on the second eccentric rod 1006 for horizontal rotation, and a fixing rod 1008 is provided for horizontal rotation on the other end of the connecting rod 1007, and the lower end of the fixing rod 1008 is fixedly disposed. A connecting frame 1009 fixedly connected to the slide plate 22 is provided. When in use, the driving shaft 19 rotates to drive the first bevel gear 1001 to rotate, so that the second bevel gear 1002 meshing therewith rotates, so that the rotating rod 1003 and the second rotating disk 1005 rotate, and the second eccentric rod 1006 at the eccentric position rotates through the rotation of the second rotating disk 1005, thereby driving the connecting rod 1007 to swing back and forth, and the connecting rod 1007 pulls the fixed rod 1008 and the connecting frame 1009 to swing back and forth, and the connecting frame 1009 drives the slide plate 22 to rotate. Under the limiting action of the guide sleeve 23, the slide plate 22 swings back and forth. Since the driving shaft 19 and the driven shaft 16 rotate in opposite directions, the two slide plates 22 slide back and forth in opposite directions, that is, when one of the slide plates 22 slides backward, the other slide plate 22 slides forward, so that the plastic fragments and film fragments accumulated on the upper sides of the two slide plates 22 can be shaken and discharged, so that the plastic fragments and film fragments are more evenly distributed in the gaps between the two slide plates 22, and the discharge of the plastic fragments and film fragments is more uniform and continuous, which is convenient for subsequent separation.

[0042] like Figure 2 , Figure 6 , Figure 7 , Fig.15As shown, a blower mechanism 18 is provided on one side of the separation cylinder 4, and the blower mechanism 18 includes a hot air blower 1801 fixedly arranged on one side of the separation cylinder 4, and a plurality of blow pipes 1802 located on the inner side of the separation cylinder 4 and blowing horizontally are provided at the output end of the hot air blower 1801, and the plurality of blow pipes 1802 are arranged in multiple rows, and a film discharge assembly 12 cooperating with the blower mechanism 18 is provided on the other side of the separation cylinder 4, and the film discharge assembly 12 includes a film fragment discharge port 1203 opened on the other side of the separation cylinder 4 and cooperating with the blow pipe 1802, and a film fragment discharge pipe 1201 connected to the film fragment discharge port 1203 is fixedly arranged on the outer side of the separation cylinder 4, and the film fragment discharge pipe 1201 adopts a 1 / 4 elbow structure to facilitate the collection of film fragments, and a plurality of ventilation holes 1202 are provided on the upper side wall of the film fragment discharge pipe 1201. When in use, when plastic fragments and film fragments are discharged from the space between the two slides 22, When the gap is uniform and continuous, the hot air can be blown out horizontally from several blowing pipes 1802 through the hot air blower 1801. Since the weight of the film fragments is less than that of the plastic fragments, the hot air will blow the film fragments out of the plastic fragments, so that the film fragments enter the inner side of the film fragment discharge pipe 1201 from the film fragment discharge port 1203, and the excess hot air is discharged through the vent holes 1202 on the upper side of the film fragment discharge pipe 1201, and finally the film fragments are discharged and collected from the lower end outlet of the film fragment discharge pipe 1201. In general, the inside or outer surface of the plastic bottle is relatively moist and impurities will adhere to it. The hot air can also dry the moist impurities adhering to the plastic fragments or film fragments, so that the dried impurities are separated from the plastic fragments or film fragments, and since the weight of the dried impurities is relatively small, they will also be discharged through the film fragment discharge pipe, thereby improving the separation effect and the effect of subsequent cleaning.

[0043] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Fig.11 , Fig.12 , Fig.18As shown, the lower side of the separation cylinder 4 is connected to a cleaning cylinder 5, and a sludge discharge port 21 is provided at the bottom of the cleaning cylinder 5. A sealing bottom plate 6 that is sealed with the sludge discharge port 21 is rotatably provided on one side of the bottom of the cleaning cylinder 5. Electric telescopic rods 601 that drive the sealing bottom plate 6 to open are rotatably provided on the front and rear sides of the cleaning cylinder 5. The electric telescopic rod 601 can drive the sealing bottom plate 6 to open, so that the sludge discharge port 21 at the bottom of the cleaning cylinder 5 is opened, so that the sludge settled at the bottom of the cleaning cylinder 5 can be discharged. The side wall of the cleaning cylinder 5 is sealed and disassembled with a sealing side plate 26. The sealing side plate 26 is fixed to the side wall of the cleaning cylinder 5 by screws. When unloading is required, only the sealing side plate 26 needs to be opened to unload the cleaned plastic fragments. One side of the cleaning cylinder 5 A water inlet pipe 8 is arranged at the upper part, and the water inlet pipe 8 can discharge clean water into the inner side of the cleaning cylinder 5. A water outlet pipe 11 is arranged at the bottom of one side of the cleaning cylinder 5, and the water outlet pipe 11 can discharge the clean water inside the cleaning cylinder 5. Valves are arranged on the water inlet pipe 8 and the water outlet pipe 11. A sealing lifting plate 20 is arranged at the bottom of the inner side of the cleaning cylinder 5 for vertical sliding sealing. A rubber sealing strip is arranged at the edge of the sealing lifting plate 20, and the sealing lifting plate 20 can be sealed and fitted with the inner wall of the cleaning cylinder 5 through the rubber sealing strip. A plurality of water spray holes 2001 are opened on the sealing lifting plate 20. A reciprocating mechanism 9 is arranged on the upper side of the sealing lifting plate 20. The reciprocating mechanism 9 includes a first rotating disk 901 fixedly arranged at one end of the driving shaft 19 and the driven shaft 16. The eccentric position of the first rotating disk 901 A first eccentric rod 903 is fixedly provided, and a transmission assembly 902 is rotatably sleeved on the first eccentric rod 903. The lower end of the transmission assembly 902 is rotatably connected to a connecting bracket 904 that slides through the separation cylinder 4 and is fixedly connected to the sealing lifting plate 20. The connecting bracket 904 adopts a "7"-shaped structure, and the bottom of the connecting bracket 904 is fixedly connected to the sealing lifting plate 20 by screws, which is convenient for removing the sealing lifting plate 20, improving the sludge unloading efficiency, and facilitating cleaning. A slide groove 905 that cooperates with the connecting bracket 904 is vertically provided on the front side of the separation cylinder 4. The slide groove 905 facilitates the vertical sliding of the connecting bracket 904, which plays a guiding role with the connecting bracket 904. The side wall of the slide groove 905 is provided with a limiting groove 906. The outer fixed sleeve of 904 is provided with a limiting plate 907 which is slidably connected with the limiting groove 906. The limiting plate 907 slides vertically in the limiting groove 906, so that the connecting bracket 904 is vertically limited to prevent the connecting bracket 904 from getting stuck. When in use, the driving shaft 19 rotates to drive the first turntable 901 to rotate, so that the first eccentric rod 903 at the eccentric position of the first turntable 901 rotates, thereby driving the transmission component 902 to swing up and down, thereby pulling the connecting bracket 904 to move up and down. Since the horizontal end of the connecting bracket 904 penetrates through the slide groove 905, the horizontal end of the connecting bracket 904 will move up and down in the slide groove 905. The connecting bracket 904 drives the sealing lifting plate 20 at the bottom of the inner side of the cleaning cylinder 5 to slide up and down.Since the bottom of the cleaning cylinder 5 is sealed, clean water is provided inside the cleaning cylinder 5, and a water spray hole 2001 is provided on the sealing lifting plate 20, when the sealing lifting plate 20 slides down, the clean water on the lower side of the sealing lifting plate 20 will be squeezed and sprayed upward from the water spray hole 2001, so that the clean water will flush the plastic fragments. Since the crushed plastic fragments are accumulated on the upper side of the sealing lifting plate 20 due to gravity, the sprayed clean water will impact the plastic fragments, on the one hand, the impurities on the surface of the plastic fragments are cleaned, and on the other hand, the plastic fragments and the clean water are disturbed to achieve the effect of stirring the clean water, so that the plastic fragments are more fully in contact with the clean water, and the cleaning effect and efficiency of the plastic fragments are further improved.

[0044] like Figure 1 , Fig. 9 As shown, the transmission assembly 902 includes a sliding sleeve 9021 rotatably connected to the first eccentric rod 903 and a sliding rod 9022 rotatably sleeved on one end of the connecting bracket 904. The upper end of the sliding rod 9022 is slidably inserted into the inner side of the sliding sleeve 9021. The upper end of the sliding rod 9022 is provided with a plurality of threaded holes 9024. The lower end of the sliding sleeve 9021 is provided with a plurality of positioning holes 9023 that match the threaded holes 9024. The outer side of the sliding sleeve 9021 is provided with a plurality of positioning holes 9023 that pass through the positioning holes 9023 and are screwed with the threaded holes 9024. The positioning screw 9025 connected with the thread can pass through different positioning holes 9023 and be connected with different threaded holes 9024 when in use, so that the sliding rod 9022 can slide in and out of one end of the sliding sleeve 9021, and the height of the connecting bracket 904 at the lower end of the sliding rod 9022 can be adjusted, thereby adjusting the initial position of the sealing lifting plate 20, so that the sealing lifting plate 20 can meet the spraying and washing of plastic fragments of different volumes, thereby improving the practicability of the plastic recycling equipment.

When in use, the stirring motor 17 drives the stirring shaft 2501 to rotate horizontally inside the cleaning cylinder 5, so that the multiple stirring shafts 2501 outside the stirring shaft 2501 and the multiple bristles 2503 on the stirring shaft 2501 can rotate, so that the upper surface of the plastic fragments inside the cleaning cylinder 5 is brushed and the sludge on the upper surface of the plastic fragments is brushed off. In the process of stirring and cleaning, the air is pumped into the air inlet channel 2506 inside the stirring shaft 2501 through the adapter 2508 by the cold air fan 2507, and then enters the interior of the stirring rod 2502 through the air inlet channel 2506, and finally blown out through the second air outlet 2505 and the first air outlet 2504 on the side wall and end of the stirring rod 2502, which can further improve the impact between the plastic fragments and the clean water, and improve the cleaning effect and efficiency of the plastic fragments.

[0046] It should be noted that, when using this plastic recycling equipment, first, clean water is discharged into the inner side of the cleaning cylinder 5 through the water inlet pipe 8, and then the valve on the water inlet pipe 8 is closed, and then the plastic bottles are poured from the feed hopper 3 into the first crushing cylinder 1 and the second crushing cylinder 2, and then the crushing motor 13 drives the driving shaft 19 to rotate, so that the crushing roller 2401 on the driving shaft 19 rotates inside the second crushing cylinder 2, and then the crushing roller 2401 and the crushing blade 2402 inside the second crushing cylinder 2 rotate from top to bottom toward the connecting part, and at the same time, the rotation of the driving shaft 19 will drive the driving gear 14 thereon to rotate, and then drive the driven gear 15 to rotate in the opposite direction, and then drive the driven shaft 16 to rotate in the opposite direction, and then drive the driven shaft The crushing roller 2401 on 16 rotates inside the first crushing cylinder 1, so that the crushing roller 2401 and the crushing blade 2402 inside the first crushing cylinder 1 rotate from top to bottom toward the connecting part, that is, the crushing roller 2401 and the crushing blade 2402 inside the first crushing cylinder 1 and the crushing roller 2401 and the crushing blade 2402 inside the second crushing cylinder 2 rotate together in opposite directions, and rotate from top to bottom toward the connecting part at the same time, so that the plastic bottles poured into the first crushing cylinder 1 and the second crushing cylinder 2 can be crushed, and then the crushed plastic fragments and film fragments are accumulated between the two slides 22. During the crushing process, the driving shaft 19 rotates to drive the first bevel gear 1001 to rotate, so that the second bevel gear 100 meshing with it 2 rotates, so that the rotating rod 1003 and the second rotating disk 1005 rotate, and the second eccentric rod 1006 at the eccentric position rotates through the rotation of the second rotating disk 1005, and then drives the connecting rod 1007 to swing back and forth, and the connecting rod 1007 pulls the fixing rod 1008 and the connecting frame 1009 to swing back and forth, and the connecting frame 1009 drives the slide plate 22 to swing back and forth under the limiting action of the guide sleeve 23. Since the driving shaft 19 and the driven shaft 16 rotate in opposite directions, the reciprocating sliding directions of the two slide plates 22 are opposite, that is, when one of the slide plates 22 slides backward, the other slide plate 22 slides forward, so that the plastic fragments and film fragments accumulated on the upper side of the two slide plates 22 can be shaken and discharged, and then passed through the hot air blower 1 801 blows hot air horizontally from a plurality of blowing pipes 1802, so that the film fragments enter the inner side of the film fragment discharge pipe 1201 from the film fragment discharge port 1203, and the excess hot air is discharged through the vent holes 1202 on the upper side of the film fragment discharge pipe 1201, and finally the film fragments are discharged and collected from the lower end outlet of the film fragment discharge pipe 1201, and the separated plastic fragments will fall into the interior of the cleaning cylinder 5, at this time, the stirring motor 17 drives the stirring shaft 2501 to rotate horizontally on the inner side of the cleaning cylinder 5, so that the multiple stirring shafts 2501 outside the stirring shaft 2501 and the multiple bristles 2503 on the stirring shaft 2501 can rotate, so that the plastic fragments inside the cleaning cylinder 5 are stirred and cleaned, and in the process of stirring and cleaning,The air is pumped into the air inlet channel 2506 on the inner side of the stirring shaft 2501 through the adapter 2508 by the air cooler 2507, and then enters the interior of the stirring rod 2502 through the air inlet channel 2506, and finally blown out through the second air outlet 2505 and the first air outlet 2504 on the side wall and the end of the stirring rod 2502, so as to further enhance the impact between the plastic fragments and the clean water. In this process, at the same time, the driving shaft 19 rotates to drive the first turntable 901 to rotate, so that the first eccentric rod 903 at the eccentric position of the first turntable 901 rotates, thereby driving the transmission assembly 902 to reciprocate up and down. The connecting bracket 904 swings, thereby pulling the connecting bracket 904 to move up and down reciprocatingly. Since the horizontal end of the connecting bracket 904 passes through the slide groove 905, the horizontal end of the connecting bracket 904 will move up and down reciprocatingly in the slide groove 905. The connecting bracket 904 drives the sealing lifting plate 20 at the bottom of the inner side of the cleaning cylinder 5 to slide up and down reciprocatingly. Since the bottom of the cleaning cylinder 5 is sealed, the inside of the cleaning cylinder 5 is provided with clean water, and the sealing lifting plate 20 is provided with a water spray hole 2001. Therefore, when the sealing lifting plate 20 slides down, the clean water on the lower side of the sealing lifting plate 20 will be squeezed and sprayed upward from the water spray hole 2001. Since the crushed plastic fragments are accumulated on the upper side of the sealing lifting plate 20 due to gravity, the sprayed clean water will impact the plastic fragments, thereby improving the cleaning effect and efficiency of the plastic fragments. Finally, when the cleaning is completed, the sewage is discharged by opening the valve on the water outlet pipe 11, and in order to improve the drainage efficiency, the sealing bottom plate 6 can be opened to discharge the sewage and the precipitated sludge together. At this time, new clean water can be added through the water inlet pipe 8, and then a new cleaning is performed. When the cleaning is completed, the sewage is completely discharged. At this time, the sealing lifting plate 20 can be vertically lifted to make the sealing lifting plate 20 The gas on the lower side of the plate 20 is sprayed back and forth through the water spray hole 2001 onto the surface of the wet plastic fragments, so that the plastic fragments are air-dried, and at the same time, the air is pumped into the air inlet channel 2506 on the inner side of the stirring shaft 2501 through the adapter 2508 by the cold air blower 2507, and then enters the interior of the stirring rod 2502 through the air inlet channel 2506, and finally blows out through the second air outlet hole 2505 and the first air outlet hole 2504 on the side wall and end of the stirring rod 2502, so that the plastic fragments on the upper side of the sealing lifting plate 20 are stirred and air-dried, so that the plastic fragments are dried, which is convenient for subsequent storage and transportation.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
