Description

Technical Field

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

[0002] Plastic toys are very suitable for children and young children. Plastic is safe, non-toxic, and low-cost, and is loved by consumers. The production industry of plastic toys has also flourished. Plastic toys need to be recycled after being discarded. After plastic toys are recycled, they are usually manufactured using special environmental protection equipment such as comprehensive waste utilization for recycling and reuse.

[0003] A Chinese patent with publication number CN112045900A discloses a crushing device for discarded plastic toys that can be continuously loaded, including a feeding mechanism, a first motor, a hydraulic rod, a conveyor belt body and a second motor. The feeding mechanism includes a bottom plate, the top end of the rotating shaft is fixedly connected to a second turntable, and the top end of the bottom plate is fixedly connected to a pressure bin; by providing a pressure plate, the hydraulic rod drives the pressure plate downward after being turned on, thereby compressing the plastic toys inside the pressure bin. Spherical or other difficult-to-crush toys can be better crushed and recycled after compression. When the compressed plastic toys enter the inner bin through the conveyor belt body, the plastic toys can be smoothly crushed by the crushing roller, which greatly improves the crushing efficiency of the device, so that the device has a good crushing effect when facing toys of various difficult-to-crush shapes, thereby improving the scope of application of the device.

[0004] In the current existing technology, by compressing plastic toys and then crushing them, it is convenient to crush various toys with difficult-to-break shapes. However, plastic toys also contain some metal parts. If the metal parts are not sorted and melted together with the plastic, the metal requires a higher temperature to melt, and the plastic may have decomposed or burned in the process, resulting in the metal being unable to be effectively recovered. Metal impurities are mixed into the plastic melt, reducing the quality of the recycled plastic and affecting its reuse value.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 6 As shown, a waste plastic toy recycling device described in an embodiment of the present invention includes a box body 1; a crushing box 2 is provided on the box body 1, a conveyor belt 41 is provided under the crushing box 2, and a plurality of fixed frames 42 are fixed to the bottom of the box body 1; two fixed plates 4 are fixed to the multiple fixed frames 42, and both ends of the two fixed plates 4 are rotatably connected to a rotating rod 43, and the conveyor belt 41 is sleeved on the two rotating rods 43; the conveyor belt 41 is arranged at an angle; an iron removal mechanism is provided at one end of the conveyor belt 41 away from the crushing box 2; the iron removal mechanism includes two mounting frames 44 fixed to the fixed plate 4, and the two mounting frames 44 are rotatably connected to a rotating belt 442 through a rotating rod 441, and the outer surface of the rotating belt 442 is covered with an iron remover; a rotating mechanism is provided at one end of the rotating rod 43; a driving mechanism is provided at one end of the rotating rod 441; a wind-raising mechanism is provided at the bottom of the crushing box 2; and a cleaning mechanism is provided at both ends of the rotating belt 442.

[0025] Plastic toys are polymer compounds made from monomers through polyaddition or polycondensation reactions. They have moderate deformation resistance, somewhere between that of fiber and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Therefore, they are generally recyclable. Recycled plastic toys are then manufactured using specialized environmentally friendly equipment, such as waste comprehensive utilization, for reuse. Existing technologies do not separate metal parts. Because metals require higher temperatures to melt, the plastics may decompose or burn during the melting process, making it impossible to effectively recover the metal. Metallic impurities can be mixed into the plastic melt, reducing the quality of the recycled plastic and its reusability.

[0026] When the iron removal mechanism provided by the present invention is in use, the plastic toys are first crushed into fragments by the crushing box 2. The fragments fall from the crushing box 2 onto the conveyor belt 41 below. During the falling process, the fragments and metal parts are blown away by the wind-raising mechanism, and then transported upward to the bottom of the rotating belt 442 under the action of the conveyor belt 41. Since the outer wall of the rotating belt 442 is covered with an iron remover, the iron impurities on the conveyor belt 41 are magnetically attracted and adhered to the rotating belt 442 through the iron remover. Then, during the rotation of the rotating belt 442, the iron impurities are scraped off and recycled under the action of the cleaning mechanism; the plastic fragments on the conveyor belt 41 continue to be transported to the next process for processing, thereby realizing the function of sorting iron and plastic.

[0027] like Figure 4 and Figure 6As shown, the cleaning mechanism includes scrapers 443 fixed on two mounting frames 44, the scrapers 443 are all tilted upward and in contact with the surface of the iron remover; the mounting frames 44 are also fixed with guide plates 444, the guide plates 444 are all tilted downward, and a recovery box 11 is provided at the bottom.

[0028] The cleaning mechanism provided by the present invention is used to clean iron impurities on the rotating belt 442 when in use. During the rotation of the rotating belt 442, the iron impurities come into contact with the scraper 443, are squeezed and scraped off by the scraper 443, fall onto the guide plate 444, and finally slide into the recovery box 11 through the guide plate 444, thereby achieving the cleaning and recovery of the iron impurities.

[0029] like Figure 2 and Figure 4 As shown, a feed hopper 21 is installed on the top of the crushing box 2; two crushing rollers 23 are rotatably connected to the inner wall of the crushing box 2 through roller shafts; a guide plate 22 is provided above the crushing rollers 23, and the guide plate 22 is fixed to the inner wall of the crushing box 2; one end of the roller shaft extends to the outside of the crushing box 2 and is fixed to a first gear 232; a first motor 231 is provided at one end of one of the roller shafts.

[0030] The crushing roller 23 provided by the present invention is used to crush plastic toys when in use. By turning on the first motor 231, the output shaft of the first motor 231 drives the roller shaft to rotate. During the rotation process, the roller shaft drives the first gear 232 and the connected crushing roller 23 to rotate. The first gear 232 drives the other first gear 232 to rotate, and the other first gear 232 drives the connected roller shaft and crushing roller 23 to rotate. The two crushing rollers 23 rotate synchronously in opposite directions to crush the plastic toys into fragments, wherein the guide plate 22 is used to block the fragments or small parts to prevent them from falling without being crushed.

[0031] like Figure 1 and Figure 2 As shown, a heating cylinder 31 is fixedly connected to the bottom end of the box body 1, a feeding cylinder 3 is sleeved inside the heating cylinder 31, a third motor 34 is fixedly connected to the outer wall of the feeding cylinder 3, the output shaft of the third motor 34 is rotatably connected to the feeding cylinder 3, the output shaft of the third motor 34 is fixedly connected to the rotating shaft, and a spiral blade 32 is fixedly connected to the outer wall of the rotating shaft; the end of the feeding cylinder 3 close to the conveyor belt 41 is connected and fixedly connected to a receiving hopper 35, and the receiving hopper 35 is opposite to the discharge end of the conveyor belt 41; the bottom of the end of the feeding cylinder 3 away from the box body 1 is connected and fixedly connected to a lower hopper 33.

[0032] When the feeding cylinder 3 and the heating cylinder 31 provided by the present invention are in use, the sorted fragments fall into the receiving hopper 35 through the discharge end, and then the fragments are heated, melted, extruded and granulated. The fragments are uniformly extruded and granulated for easy storage and reuse; in the extrusion granulation process, a purification device is usually set to prevent the odor generated by the plastic melt from harming the body and the environment.

[0033] like Figure 4 As shown, the rotating mechanism includes a first rotating wheel 233 fixed to one end of the roller shaft, a second rotating wheel 431 fixed to one end of the rotating rod 43 close to the crushing box 2, and a belt 234 is provided between the first rotating wheel 233 and the second rotating wheel 431.

[0034] The rotating mechanism provided by the present invention is used to drive the conveyor belt 41 to rotate when in use, and drives the crushing roller 23 to rotate through the first motor 231 to crush plastic toys. During the rotation of the roller shaft, the first rotating wheel 233 is driven to rotate by the roller shaft, and the belt 234 is driven to rotate by the first rotating wheel 233, and the second rotating wheel 431 is driven to rotate by the belt 234, and the rotating rod 43 is driven to rotate by the second rotating wheel 431, and the conveyor belt 41 is driven to rotate by the rotating rod 43, so as to convey the crushed fragments; and the diameter of the first rotating wheel 233 is smaller than the diameter of the second rotating wheel 431, so the rotation speed of the conveyor belt 41 is slower than the rotation speed of the crushing roller 23, which is conducive to wind blowing and iron removal.

[0035] like Figure 6 As shown, the driving mechanism includes a worm gear 445 fixed to one end of the rotating rod 441; a third gear 448 is fixed to one end of the rotating rod 43 away from the crushing box 2; a worm 446 is rotatably connected to the outer wall of the fixed plate 4 through a bearing, and a second gear 447 is fixed to the outer wall of one end of the worm 446, the second gear 447 is meshed with the third gear 448, and the worm 446 is meshed with the worm gear 445.

[0036] When the driving mechanism provided by the present invention is in use, the conveyor belt 41 drives the upper rotating rod 43 to rotate during its rotation, and drives the third gear 448 to rotate through the rotating rod 43, drives the second gear 447 to rotate through the third gear 448, drives the worm 446 to rotate through the second gear 447, drives the worm gear 445 to rotate through the worm 446, drives the rotating rod 441 to rotate through the worm gear 445, and drives the rotating belt 442 to rotate through the rotating rod 441, thereby realizing the function of driving the rotating belt 442 to rotate.

[0037] like Figure 4 and Figure 7As shown, a plurality of rotating plates 411 are rotatably connected to the outer wall of the conveyor belt 41, and two connecting blocks 417 are fixedly connected to the outer wall of the rotating plate 411. The connecting blocks 417 are rotatably connected to connecting rods 416 through pins, and one end of the connecting rods 416 is rotatably connected to sliders 415 through pins. A plurality of sliding grooves 412 are provided on the outer wall of the conveyor belt 41; sliding rods 413 are fixedly connected to the inner walls of the sliding grooves 412, and the sliders 415 are slidably connected to the sliding rods 413 respectively; and springs 414 are sleeved on the outer sides of the sliding rods 413.

[0038] When the rotating plate 411 provided by the present invention is in use, some plastics contain moisture and are not air-dried. The crushed fragments may stick to the conveyor belt 41 or the rotating plate 411. When the rotating plate 411 rotates to the discharging end to discharge the material, the elastic force of the spring 414 will also change due to the change in gravity, and the slider 415 will rotate. The slider 415 drives the rotating plate 411 to rotate and shake through the connecting rod 416, thereby facilitating the unloading of the fragments.

[0039] like Figure 8 As shown, the wind-raising mechanism includes a bellows 24 fixed to the bottom of the crushing box 2, and two fans 241 are installed in the bellows 24. The wind direction of the fans 241 is directly facing the inclined surface of the conveyor belt 41; a dustproof plate 242 is fixed to the side wall of the bellows 24 close to the conveyor belt 41.

[0040] When the wind-raising mechanism provided by the present invention is in use, the wind force of the fan 241 blows fragments of different masses to different positions and spreads them out in zones. The lighter ones are blown farther away, while the heavier ones are blown closer, thereby preventing the fragments from piling up and making iron removal inconvenient, and improving the efficiency of iron removal.

[0041] like Figure 9 As shown, two inclined plates 25 are rotatably connected to the inner wall of the crushing box 2 through a rotating shaft, and the two inclined plates 25 are in an inverted V shape. A lifting plate 255 is provided below the inclined plate 25; the two ends of the lifting plate 255 are respectively in contact with the bottom of the inclined plate 25; two side plates 251 are fixedly connected to the inner wall of the box body 1; a reciprocating screw rod 252 is rotatably connected between the two side plates 251 through a bearing; the lifting plate 255 is threadedly connected to the reciprocating screw rod 252; two guide rods 253 are fixedly connected between the two side plates 251, and the lifting plate 255 is slidably connected to the two guide rods 253; a second motor 254 is provided at the bottom of the reciprocating screw rod 252.

[0042] The inclined plate 25 provided by the present invention is used to control the discharge speed when in use. The crushed plastic fragments may block the bottom of the crushing box 2 and make it inconvenient to discharge the material. The second motor 254 is turned on, and the reciprocating screw rod 252 is driven to rotate by the second motor 254. The reciprocating screw rod 252 drives the lifting plate 255 to reciprocate up and down. The inclination angle of the inclined plate 25 is adjusted by the position of the lifting plate 255. When adjusted to a suitable angle, it is convenient to control the discharge speed and prevent the bottom of the crushing box 2 from being blocked.

[0043] like Figure 5 As shown, the bottom of the recovery box 11 is hinged with a blocking plate 13, and the bottom of the blocking plate 13 is provided with a knob 12, and the knob 12 is rotatably connected to the bottom of the box body 1.

[0044] The blocking plate 13 provided by the present invention is used to block the recovery box 11 when in use, and the blocking plate 13 is closed by the knob 12 to facilitate the recovery and discharge of iron impurities.

[0045] Working principle: Recycled plastic toys are manufactured and reused through special environmental protection equipment such as waste comprehensive utilization. First, the first motor 231 is turned on, and the output shaft of the first motor 231 drives the roller shaft to rotate. During the rotation of the roller shaft, the first gear 232 and the connected crushing roller 23 are driven to rotate. The first gear 232 drives another first gear 232 to rotate, and the other first gear 232 drives the connected roller shaft and crushing roller 23 to rotate. The two crushing rollers 23 rotate synchronously in opposite directions to crush the plastic toys into fragments. During the rotation of the roller, the roller drives the first rotating wheel 233 to rotate, the first rotating wheel 233 drives the belt 234 to rotate, the belt 234 drives the second rotating wheel 431 to rotate, the second rotating wheel 431 drives the rotating rod 43 to rotate, and the rotating rod 43 drives the conveyor belt 41 to rotate, thereby conveying the crushed fragments; During the falling process, the wind force of the fan 241 blows the fragments of different masses to different positions and spreads them out in different areas. The lighter ones are blown farther away, and the heavier ones are blown closer, so as to prevent the fragments from piling up and making it inconvenient to remove iron. Then, under the action of the conveyor belt 41, the fragments are transported upward to the bottom of the rotating belt 442. Since the outer wall of the rotating belt 442 is covered with an iron remover, the iron impurities on the conveyor belt 41 are magnetically attracted and attached to the rotating belt 442 through the iron remover. During the rotation of the conveyor belt 41, the conveyor belt 41 drives the rotating rod 43 above to rotate. The third gear 448 is driven to rotate by the rotating rod 43, the second gear 447 is driven to rotate by the third gear 448, the worm 446 is driven to rotate by the second gear 447, the worm 445 is driven to rotate by the worm 446, the rotating rod 441 is driven to rotate by the worm gear 445, and the rotating belt 442 is driven to rotate by the rotating rod 441. During the rotation of the rotating belt 442, the iron impurities come into contact with the scraper 443, are squeezed and scraped by the scraper 443, fall onto the guide plate 444, and finally slide into the recovery box 11 through the guide plate 444, thereby achieving the cleaning and recovery of the iron impurities; The plastic fragments on the conveyor belt 41 fall into the receiving hopper 35 through the discharge end, and then the fragments are heated, melted, and extruded into granules. The fragments are uniformly extruded and granulated for easy storage and reuse. During the extrusion granulation process, a purification device is usually set up to prevent the odor generated by the plastic melt from harming the body and the environment.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments.
