Description

Technical Field

[0001] The invention belongs to the technical field of plastic recycling, in particular to a device for crushing and recycling recycled plastic waste. Background Art

[0002] Plastics are difficult to degrade in the natural environment. Recycling plastics can protect the balance of the ecosystem. When recycling plastics, plastic crushing is a key link in the plastic recycling process. The cleaned plastic waste is transferred to the crusher for crushing and cutting it into smaller particles, thereby improving the uniformity of the recycled plastic and facilitating subsequent other recycling operations.

[0003] A patent application with publication number CN110154270A discloses a plastic bottle recycling device, including a shell, a flattening chamber and a compression mechanism for flattening plastic bottles. The flattening chamber is arranged inside the shell, the feed port is arranged on the shell, and the feed port is connected to the flattening chamber, and the discharge port is arranged at the bottom of the flattening chamber. During the recycling process of plastic bottles, the device can deflate the plastic bottles before flattening them, and has the advantage of being able to discharge the remaining water in the bottle without causing it to burst.

[0004] The above scheme still has some problems in practical application. When the above device is used to crush and recycle plastic bottles, a large number of plastic bottles will be transported to the inside of the device through a conveyor belt for crushing. However, during the crushing process, the label film on the outer surface of the plastic bottle will be crushed together with the bottle body of the plastic bottle. Since the tool generates friction and heat during cutting, these label films are easy to stick to the cutting tool. Moreover, if the label film and the bottle body are subsequently crushed into a container, the different melting temperature differences between the label film and the bottle body will also lead to unstable performance of the recycled plastic, thereby increasing recycling costs and reducing safety.

[0005] To this end, the present invention provides a device for crushing and recycling recycled plastic waste. Summary of the Invention

[0036] Specifically, the scheme is a recycling resource crushing and recycling device for plastic waste, which is mainly used for recycling plastic waste such as plastic bottles 5. When in use, the plastic bottle 5 is first placed inside the rotating frame 21, and then the rotating frame 21 is started to rotate. The rotating frame 21 will drive the plastic bottle 5 inside to rotate together. During the rotation, the plastic bottle 5 will be thrown into contact with the inner wall of the blocking plate 22, and finally, under the action of centrifugation, a plastic bottle 5 will move from the rotating frame 21 to the inside of the guide bar 23. At this time, the rotating frame 21 is closed and the connecting arm 306 is started. The connecting arm 306 will be on the connecting plate The inner wall of 312 rotates, and in the process of rotation, the placement table 307 is driven to rotate together, and finally the placement table 307 will move to block the hole on the surface of the first fixing plate 11, and then the plastic bottle 5 will fall on the surface of the placement table 307. At this time, the pressing bar 303 and the cutting frame 316 are started to rotate, and the pressing bar 303 will rotate to contact the upper end of the plastic bottle 5. Through the cooperation of the pressing bar 303 and the placement table 307, the plastic bottle 5 will be fixed at this time, and then the rotating cutting frame 316 will drive the cutting knife 318 to move together, and in the process of moving, the cutting knife 318 will The label film on the surface of the plastic bottle 5 will come into contact with the label film, thereby cutting the label film on the surface of the plastic bottle 5 during the movement, so that the plastic bottle 5 and the label film are separated. No matter whether the bottle mouth of the plastic bottle 5 is facing up or down, the structure can cut off the label film, thereby avoiding the plastic bottle 5 and the label film from being crushed together, and then the separated label film can be taken out. At this time, the pressing bar 303 and the cutting frame 316 are started again, the pressing bar 303 and the cutting knife 318 will be reset, and then the connecting arm 306 is started, and the connecting arm 306 will drive the placing table 307 to reset, so that the plastic bottle 5 can be taken out from the first The plastic bottle 5 falls from a hole on the surface of a fixing plate 11 and falls into the inside of the crushing frame 401. Then, the crushing knife 402 is started to rotate, and the plastic bottle 5 can be crushed. When the device is recycling the plastic bottles 5, the rotating frame 21 can sort and transport a large number of plastic bottles 5, so that the recycling of plastic bottles 5 can be carried out on a large scale. In addition, during the transportation process, the cutting knife 318 can separate the label film from the bottle body of the plastic bottle 5, thereby avoiding the label film and the bottle body being broken into one container. The different melting temperature difference between the label film and the bottle body leads to unstable performance of the recycled plastic.

[0037] like Figures 1 to 11As shown, the conveying structure 2 further includes: a motor 28, which is provided at the upper end of the first fixed plate 11 and is used to control the rotation of the rotating frame 21; a conveying frame 25, which is provided at one end of the blocking plate 22, and a conveying belt 27 is provided inside the conveying frame 25, and a plurality of guide bars 23 are connected to the conveying frame 25; the separation structure 3 further includes: a fixed plate 301, which is provided on the upper surface of the first fixed plate 11, and a rotating frame 302 is provided at the upper end of the fixed plate 301; a transfer gear 31 4. The transfer gear 314 is rotatably connected to the inner wall of the rotating frame 302; the connecting rod 313 is provided on the surface of the transfer gear 314, and the connecting rod 313 is connected to the cutting frame 316; the fixed gear 315 is provided on the inner wall of the rotating frame 302, and the fixed gear 315 is engaged with the transfer gear 314; the second gear buckle 321 is provided at one end of the fixed gear 315, and the second gear buckle 321 is rotatably connected to the inner wall of the pressing bar 303.

[0038] Specifically, when the plastic bottle 5 is placed inside the rotating frame 21, the motor 28 is started, and the motor 28 will drive the rotating frame 21 to rotate, thereby transferring the plastic bottle 5 to the inside of the guide bar 23, and then the transfer gear 314 is started to rotate. During the rotation process, the transfer gear 314 will not only drive the cutting frame 316 to move through the connecting rod 313, thereby cutting the label film of the plastic bottle 5, but also the transfer gear 314 will drive the fixed gear 315 to rotate by engaging with the fixed gear 315. During the rotation process, the fixed gear 315 will drive the pressing bar 303 to rotate together, thereby fixing the plastic bottle 5 , since the transfer gear 314 drives the cutting frame 316 to rotate continuously, by providing the second gear buckle 321, when the pressing bar 303 is not in contact with the plastic bottle 5, due to the friction between the second gear buckle 321 and the pressing bar 303, the pressing bar 303 will be driven by the fixed gear 315 to rotate normally. Subsequently, when the pressing bar 303 contacts the plastic bottle 5, the pressing bar 303 at this time will be restricted by the plastic bottle 5 and cannot rotate, but the second gear buckle 321 will still rotate on the inner wall of the pressing bar 303, so that the pressing bar 303 can fix the plastic bottle 5 and the cutting frame 316 can cut the plastic bottle 5 normally.

[0039] like Figures 1 to 11 As shown, an auxiliary gear 310 is provided at one end of the connecting arm 306 , and a rack 304 is slidably connected inside the second fixing plate 12 , and the auxiliary gear 310 and the transfer gear 314 are both engaged with the rack 304 during operation.

[0040] Specifically, by setting the rack 304, when the plastic bottle 5 moves to the inside of the guide bar 23, the cylinder at the lower end of the rack 304 is started, and the cylinder will drive the rack 304 to move upward. During the movement, the rack 304 will first engage with the auxiliary gear 310, so that the auxiliary gear 310 drives the connecting arm 306 to move, thereby blocking the holes on the surface of the first fixing plate 11. Then, when the rack 304 continues to move upward, it will engage with the transfer gear 314, and finally separate the label film from the plastic bottle 5. During the movement, the rack 304 can simultaneously drive the placement table 307, the cutting frame 316 and the pressing bar 303 to move together.

[0041] like Figures 1 to 6 As shown, a gear sleeve 311 is provided on the surface of the connecting plate 312 , a first gear buckle 309 is provided on one side of the connecting arm 306 , and the first gear buckle 309 is provided inside the gear sleeve 311 .

[0042] Specifically, by setting the first gear buckle 309, in the initial state, due to the friction between the first gear buckle 309 and the gear sleeve 311, the first gear buckle 309 can drive the connecting arm 306 to be fixed at any height, thereby facilitating the placement of the plastic bottle 5 on the surface of the placement table 307, and when the rack 304 is engaged with the auxiliary gear 310, the first gear buckle 309 can also rotate normally inside the gear sleeve 311, thereby not affecting the resetting of the placement table 307.

[0043] like Figures 5 to 8 As shown, an adjustment spring 317 is provided at both ends of the cutting knife 318 , and one end of the adjustment spring 317 is connected to the cutting frame 316 .

[0044] Specifically, by setting the adjustment spring 317, when the cutting knife 318 cuts the label film of the plastic bottle 5, the adjustment spring 317 can automatically adjust the angle of the cutting knife 318 according to the distance between the cutting knife 318 and the plastic bottle 5, thereby protecting the cutting knife 318 from damage during the process of achieving precise cutting.

[0045] like Figures 5 to 10 As shown, an auxiliary pad 308 is provided on the surface of the placement table 307 .

[0046] Specifically, by providing the auxiliary pad 308 , when the placement table 307 contacts the plastic bottle 5 , the auxiliary pad 308 can prevent the plastic bottle 5 from slipping during the fixing process and can also reduce the wear of the plastic bottle 5 on the placement table 307 .

[0047] like Figures 1 to 12 As shown, the lower end of the cutting frame 316 is rotatably connected to a rope winding shaft 319 , and a separating knife 323 is provided on the surface of the rope winding shaft 319 .

[0048] Specifically, when the cutting knife 318 cuts the label film of the plastic bottle 5, the rope winding shaft 319 is started to rotate, and the rope winding shaft 319 will drive the separation knife 323 to rotate together. During the rotation, the separation knife 323 will rotate into the cutting seam and insert into the inside of the label film during rotation, and finally roll up the cut label film to separate the label film from the plastic bottle 5, making it easier for the operator to take out the label film separately.

[0049] like Figures 1 to 12 As shown, a winding roller 305 is provided inside the rotating frame 302, and a pulling rope 320 is sleeved on the surface of the rope winding shaft 319 at the lower end of the separation knife 323, and one end of the pulling rope 320 is connected to the winding roller 305, and a winding spring 322 is provided at the connection between the rope winding shaft 319 and the cutting frame 316.

[0050] Specifically, by setting up a winding roller 305, when the cutting frame 316 drives the cutting knife 318 to cut, the winding roller 305 will drive the rope winding shaft 319 to rotate through the pull rope 320, so that the separation knife 323 rolls up the label film, and then when the cutting frame 316 is reset, the winding spring 322 will release the elastic force, thereby driving the pull rope 320 to reset.

[0051] Example 2: Figures 1 to 4 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a suspension arm 24 is provided at the upper end of the blocking plate 22 , and an auxiliary plate 29 is provided at the lower end of the suspension arm 24 .

[0052] Specifically, by providing the auxiliary plate 29 , when the plastic bottle 5 is located inside the rotating frame 21 , the auxiliary plate 29 can guide the moving direction of the plastic bottle 5 , thereby making it easier for the plastic bottle 5 to enter the interior of the conveying frame 25 .

[0053] like Figures 1 to 4 As shown, a limiting plate 26 is provided at the upper end of the conveying frame 25 .

[0054] Specifically, by setting the limiting plate 26, before the plastic bottle 5 moves into the conveying frame 25, the limiting plate 26 will limit the state of the plastic bottle 5, so that only the plastic bottle 5 whose arc surface contacts the conveyor belt 27 can pass through.

[0055] Working principle: When in use, first place the plastic bottle 5 inside the rotating frame 21, then start the motor 28, the motor 28 will drive the rotating frame 21 to rotate, the plastic bottle 5 will be thrown into contact with the inner wall of the blocking plate 22 during the rotation, and finally transferred to the inside of the guide bar 23 under the action of centrifugal force, at this time, the cylinder at the lower end of the rack 304 is started, the cylinder will drive the rack 304 to move upward, during the movement, the rack 304 will first mesh with the auxiliary gear 310, so that the auxiliary gear 310 drives the connecting arm 30 6 moves, and in the process of rotation, drives the placement table 307 to rotate together, and finally the placement table 307 will move to block the hole on the surface of the first fixing plate 11, and then the plastic bottle 5 will fall on the surface of the placement table 307, and then when the rack 304 continues to move upward, it will mesh with the transfer gear 314, and the transfer gear 314 will rotate. During the rotation process, the transfer gear 314 will drive the cutting frame 316 to move through the connecting rod 313, and the rotating cutting frame 316 will drive the cutting knife 318 to move together, and During the movement, the cutting blade 318 will come into contact with the label film on the surface of the plastic bottle 5, thereby cutting the label film on the surface of the plastic bottle 5 during the movement, so that the plastic bottle 5 is separated from the label film, and the transfer gear 314 will also drive the fixed gear 315 to rotate by meshing with the fixed gear 315. The fixed gear 315 will drive the pressing bar 303 to rotate during the rotation, thereby fixing the plastic bottle 5. When the cutting frame 316 drives the cutting blade 318 to cut, the winding roller 305 will drive the pulling rope 320 to pull the plastic bottle 5. The rope winding shaft 319 rotates, so that the separation knife 323 rolls up the label film, which makes it easier for the operator to remove the label film separately. At this time, the pressing bar 303 and the cutting frame 316 are started again, and the pressing bar 303 and the cutting knife 318 will be reset. Then the connecting arm 306 is started, and the connecting arm 306 will drive the placement table 307 to reset, so that the plastic bottle 5 can fall from the hole on the surface of the first fixing plate 11 and fall into the inside of the crushing frame 401. Then the crushing knife 402 is started to rotate, and the plastic bottle 5 can be crushed.
