DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0041] like Figures 1 to 13 As shown, the present invention provides an automobile plastic parts recycling device, comprising: a body 1, a crushing assembly 11 for crushing plastic parts, a feeding unit for conveying the plastic parts to the crushing assembly 11 for processing, and a collecting unit 3 for classifying the crushed plastic particles and recycling them.

[0042] When users or manual labor disassemble and recycle plastic parts, it is impossible to ensure that the screws or metal nameplates used to fix the plastic parts are completely removed. Plastic parts containing metal will be mixed with metal after being crushed, affecting subsequent processing.

[0043] The automobile plastic parts are fed into the body 1 through the feeding unit, crushed by the crushing component 11, and finally enter the collecting unit 3 for recycling, wherein the feeding unit includes: a conveying and unloading component 21, and a discharge hopper 22; the conveying and unloading component 21 includes: a conveyor belt 211, a magnetic component 212 fixedly installed on the surface of the conveyor belt 211, and an inclined plate; two groups of inclined plates are provided on the surface of the conveyor belt 211, and the thickness of the inclined plates gradually increases from the feeding end of the conveyor belt 211 along the conveying direction; the conveyor belt 211 is installed on the body 1. When in use, the plastic parts can be manually judged from the appearance to confirm whether the plastic parts contain metal products. If they contain metal products, the plastic parts are adsorbed on the magnetic component 212 and the conveyor belt 211 is started for transportation. If they do not contain metal products, they are directly discharged through the discharge hopper 22 When the plastic parts are adsorbed on the inclined plate, it is ensured that the plastic parts are in contact with the surface of the inclined plate. During the transmission process, the plastic parts are guided by the inclined surface of the inclined plate, and the inclined plate separates the plastic parts from the magnetic parts 212, so that the plastic parts enter the crushing assembly 11 for crushing and recovery. Specifically, when the plastic parts are adsorbed on the magnetic parts 212, the inclined surface of the inclined plate is horizontal with the magnetic surfaces of the plastic parts and the magnetic parts 212, that is, the plastic parts are adsorbed on the magnetic parts 212. When the conveyor belt 211 moves, the thickness of the inclined plate increases, gradually separating the plastic parts from the magnetic parts 212. When the magnetic parts 212 are magnetically separated from the plastic parts, the plastic parts fall onto the corresponding crushing device 115 for crushing and recovery. The plastic parts can be sorted and unloaded according to the magnetic attraction strength between the plastic parts and the magnetic parts 212.

[0044] It should be noted here that the crushing assembly 11 includes: a crushing device 115, the crushing device 115 is composed of two groups of crushing rollers, a crushing shaft that drives the crushing rollers to rotate, and a motor that drives the crushing shaft to rotate. The crushing shaft is equipped with mutually meshing transmission gears. When in use, the motor drives a group of crushing shafts to rotate, so that the crushing shaft drives the crushing rollers to rotate, and the two groups of crushing rollers are rotated relative to each other through the transmission gears to complete the crushing of the plastic parts. In addition, a cam can be installed on the crushing shaft so that when the crushing shaft rotates, the cam and the primary screen plate 112 are constantly in contact and separation, thereby improving the filtering effect of the primary screen plate 112 on plastic particles. The crushing assembly 11 is arranged in a stepped shape, and the crushing assembly 11 corresponds to the lower hopper 22 one by one; Figure 2As shown, there are three groups of crushing devices 115, among which the top crushing device 115 performs preliminary crushing on the plastic parts. As the height of the crushing device 115 decreases, the crushing accuracy of the plastic parts increases successively. That is to say, when the plastic parts fall from the conveyor belt 211 under the action of the inclined plate, they can fall to the corresponding crushing device 115 according to the suction force between the plastic parts and the magnetic parts 212. The tighter the metal on the plastic parts is magnetically attracted to the magnetic parts 212, the later the plastic parts fall from the magnetic parts 212 under the action of the inclined plate. In summary, the tighter the metal is adsorbed to the magnetic parts 212, the larger the volume of the metal. At this time, directly performing conventional precision crushing will increase the load of the crushing device 115. The advantage of this is that plastic parts containing metal can be distinguished, and the crushing accuracy of plastic parts with a large amount of metal can be gradually increased from coarse to fine, thereby avoiding increasing the load of the crushing device 115.

[0045] What needs to be supplemented for the above is that the elastic member 111 is fixedly mounted on the crushing device 115, the primary screening plate 112 is fixedly mounted on the elastic member 111, the connecting rod 113 is fixedly mounted on the primary screening plate 112, and the spring 114 is fixedly connected to the connecting rod 113; one end of the spring 114 is fixedly mounted on the crushing device 115; the primary screening plate 112 is an arc-shaped plate with sieve holes on the surface. After the plastic parts are crushed by the crushing device 115, they fall onto the surface of the primary screening plate 112. After being filtered by the primary screening plate 112, the qualified plastic particles will continue to be filtered. The unqualified particles will fall downward and stay on the surface of the primary screening plate 112, and the two ends of the primary screening plate 112 are connected to the crushing device 115 through the elastic member 111 and the spring 114 respectively. The crushing device 115 will vibrate when in use, and the elastic member 111 and the spring 114 will cause the primary screening plate 112 to vibrate, and the primary screening plate 112 is tilted. The primary screening plate 112 improves the filtering effect of the plastic when vibrating, and can transport the unqualified particles on the primary screening plate 112 to the next group of crushing devices 115 for crushing, and the crushing effect is good.

[0046] Since the plastic parts are crushed by the crushing device 115, the plastic particles are mixed with the metal, and the metal in the plastic particles needs to be separated later.

[0047] The collecting unit 3 includes: a material receiving box 32 for classifying and storing plastics and metals, and a fixed frame 31 for supporting the material receiving box 32; the fixed frame 31 includes: a separation component 311 for separating plastics and metals, a screening component 312 for secondary screening of plastics, and a cleaning component 313 for cleaning the screening component 312.

[0048] After the plastic particles are crushed, the metal and particles with unqualified particle size in the plastic particles are separated by the separation component 311 and the screening component 312, and then the qualified particles are sent to the receiving box 32 for recycling, avoiding the need for subsequent secondary screening, which affects efficiency.

[0049] The separation assembly 311 includes: a rotating shaft 3111, a gear 3112 fixedly mounted on the rotating shaft 3111, and a magnetic plate 3113 fixedly mounted on the rotating shaft 3111. The rotating shaft 3111 is rotatably mounted on the surface of the fixed frame 31, and multiple sets of rotating shafts 3111 are provided on the fixed frame 31. The screening assembly 312 includes: a rear screen plate 3121, a positioning rod 3122 fixedly mounted on the rear screen plate 3121, a second spring 3123 fixedly mounted on the positioning rod 3122, and a support frame 3124 fixedly mounted on the second spring 3123. The support frame 3124 is fixedly mounted on the surface of the fixed frame 31. The surface of the rear screen plate 3121 is provided with sieve holes, the size of which increases as the thickness of the inclined plate increases. The cleaning assembly 313 includes: a cleaning roller 3132, a fixing frame 3131 rotatably connected to the cleaning roller 3132, and a rack 3133 fixedly mounted on the fixing frame 3131; a power source is installed on the fixing frame 3131; the power source is preferably an electric telescopic rod; the magnetic plate 3113 is preferably an electromagnet.

[0050] The fixed frame 3131 moves under the drive of the power source and drives the cleaning roller 3132 to move. The surface of the cleaning roller 3132 is provided with multiple groups of protrusions that cooperate with the sieve holes. Therefore, the cleaning roller 3132 contacts the rear sieve plate 3121 and rotates when moving, and cleans the sieve holes on the surface of the rear sieve plate 3121 through the protrusions to avoid sieve hole blockage and affecting the cleaning of plastic particles. In the movement of the fixed frame 3131, the rack 3133 and the gear 3112 are engaged in sequence. The gear 3112 drives the magnetic plate 3113 to rotate. At this time, the magnetic plate 3113 rotates and the side with the metal adsorbed is rotated 180 degrees for pre-unloading preparation. Then the electromagnet stops magnetic attraction, causing the metal to fall into the metal recovery trough 322 to avoid mixing of metal and plastic and affecting subsequent processing.

[0051] This device screens plastic parts containing metal to match the appropriate crushing device 115, and screens the plastic through the primary screen plate 112 while driving the metal to be processed step by step, thereby minimizing the impact of the metal mixed in the plastic parts on the crushing device 115. After the crushing is completed, in order to avoid the re-mixing of metal and plastic and affecting the subsequent processing of the plastic, when the plastic is screened for the second time through the rear screen plate 3121, the magnetic plate 3113 can absorb the metal, thereby separating the metal from the plastic, and the use effect is good.

[0052] The above needs to be supplemented that a threaded groove 31111 is provided on the surface of the rotating shaft 3111, a rotating sleeve 3114 is rotatably installed on one end of the rotating shaft 3111, and a limiting block 31141 is fixedly installed on the inner wall of the rotating sleeve 3114; the limiting block 31141 cooperates with the threaded groove 31111, and one end of the rotating sleeve 3114 abuts against the surface of the rear sieve plate 3121, and the material receiving box 32 is slidably installed on the fixed frame 31, and a plastic recovery groove 321 and a metal recovery groove 322 are provided on the surface of the material receiving box 32; the number of plastic recovery grooves 321 corresponds to the number of sieve holes of different sizes; a limiting shaft is installed on the rotating sleeve 3114, and the limiting shaft is slidably connected to the magnetic plate 3113, that is, when the gear 3112 rotates, it moves inside the threaded groove 31111 through the limiting block 31141, causing the rotating sleeve 3114 to move axially The cleaning roller 3132 moves and exerts pressure on the rear screen plate 3121 to deform it, and the auxiliary cleaning roller 3132 cleans the rear screen plate 3121. Since the number of plastic recovery slots 321 corresponds to the number of sieve hole specifications of the rear screen plate 3121, plastics of various specifications are recovered into the corresponding plastic recovery slots 321 for centralized collection, and the cleaning roller 3132 moves, and the fixed frame 3131 moves accordingly. Since one end of the fixed frame 3131 is in contact with the rear screen plate 3121, if there are still plastic particles on the surface of the rear screen plate 3121 after the cleaning roller 3132 is completed, the fixed frame 3131 will push the plastic particles to move, and since the sieve holes on the surface of the rear screen plate 3121 gradually increase, the plastic particles will fall from the large sieve holes, thereby improving the cleaning effect of the screen plate. The rear screen plate 3121 uses conventional plastic screen plates or metal sheets on the market.

[0053] That is to say, when it is necessary to recycle plastic particles and metal particles, the power source is started. On the one hand, the rear screen plate 3121 is cleaned to avoid clogging of the rear screen. On the other hand, the metal adsorbed by the magnetic plate 3113 can be recovered and the rear screen is assisted in cleaning. The use effect is good. In addition, when the cleaning roller 3132 moves, the rack 3133 engages with the gear 3112 to assist in cleaning the rear screen. The movement of the cleaning roller 3132 and the movement of the rotating sleeve 3114 occur successively, and the cleaning effect will be better if one area of the rear screen plate 3121 is cleaned.

[0054] In addition, since the crushed particles will splash after contacting the rear screen plate 3121, the particles will splash to the edge of the rear screen plate 3121, which is inconvenient for unloading. The cleaning roller 3132 of the present application is fixedly installed with a transmission member 31321, the transmission member 31321 is rotatably connected to a transmission rod 31322, the transmission rod 31322 is fixedly connected to a connecting shaft 31325, the connecting shaft 31325 is rotatably connected to a reset member 31326, and the reset member 31326 is fixedly connected to a material stripping plate 31327, and one end of the material stripping plate 31327 is tilted. The material-dipping effect is better. The fixed frame 3131 is fixedly connected to the limiting frame 31323, and the limiting frame 31323 is fixedly connected to the inclined block 31324; one side surface of the inclined block 31324 is an inclined surface, which is used to guide the movement of the diverter plate 31327; the fixed frame 3131 and the cleaning roller 3132 are connected by a shaft, the shaft is fixedly connected to the transmission member 31321, and the shaft is rotatably connected to the fixed frame 3131; the transmission member 31321 is composed of two cams connected by bearings, and when the cleaning roller 3132 rotates, it drives the transmission member 31321 to rotate, and is connected The shaft 31325 and the reset member 31326 drive the material stripping plate 31327 to move horizontally under the limit of the limit frame 31323. When the material stripping plate 31327 contacts the inclined block 31324, it is guided by the inclined surface and tilted. The material stripping plate 31327 continues to move forward. The larger the tilt angle, the particles at the upper edge of the rear sieve plate 3121 can be sent to the center of the rear sieve plate 3121, thereby improving the filtering effect of the particles. The moving trajectory of the material stripping plate 31327 needs to be described in detail here. Under the continuous rotation of the cleaning roller 3132, the material stripping plate 31327 moves along the After the cleaning roller 3132 moves in the direction of movement and contacts the inclined block 31324, it tilts under the guidance of the inclined block 31324. The closer the distance between one end of the material stripping plate 31327 and the inclined block 31324 is, the closer the other end of the material stripping plate 31327 is to the center of the rear screen plate 3121, forming a material stripping effect. Finally, under the rotation of the cleaning roller 3132, the material stripping plate 31327 is reset. When the material stripping plate 31327 tilts under the guidance of the inclined block 31324, the reset part 31326 is deformed by force. Subsequently, when the material stripping plate 31327 is no longer in contact with the inclined plate, it can drive the material stripping plate 31327 to reset.

[0055] The cleaning roller 3132 can not only clean the rear screen plate 3121 when moving, but also can move the particles at the edge of the rear screen plate 3121 to the center of the rear screen plate 3121, so as to facilitate the unloading of the particles. When the speed of the conveyor belt 211 changes, the moving speed of the cleaning roller 3132 needs to be changed as well. The cleaning roller 3132 moves at a fast speed, and the rotating shaft 3111 quickly hits the rear screen plate 3121, and the magnetic plate 3113 rotates quickly to clean the metal particles. The cleaning roller 3132 moves at a slow speed, and the magnetic plate 3113 rotates in sequence, and the rotating shaft 3111 hits the rear screen plate 3121 in sequence, causing it to shake, and continuously cleaning the rear screen plate 3121. That is to say, when the conveyor belt 211 transmits at a fast speed, it means that the plastic parts contain a high metal content, and the magnetic plate 3113 needs to be cleaned faster after crushing. When the conveyor belt 211 moves at a slow speed, it means that the plastic parts contain a low metal content, and the plastic particles need to be cleaned more quickly. The conveyor belt 211 moves at a slow speed, so that the rear screen plate 3121 can vibrate continuously, assisting in the unloading of plastic particles, and the use effect is good.
