Description

Technical Field

[0001] This invention relates to the technical field of plastic recycling, and in particular to a recycling device for dismantling plastic products from waste household appliances. Background Technology

[0002] Plastic fragments generated from the dismantling of waste household appliances have a complex composition, often mixed with metallic impurities and adhered with various labels and tapes. Efficient purification and high-value recycling are crucial steps in resource regeneration, directly impacting the purity and subsequent processing performance of the recycled plastics. Existing recycling lines typically use multiple devices connected in series for magnetic separation, label separation, and sorting. This results in a fragmented process flow, low automation, and limited label removal effectiveness, particularly lacking targeted solutions for the problem of adhesive label residue.

[0003] In the prior art, such as Chinese Patent Publication No. CN206374080U, a label peeling device for waste plastic bottles is disclosed. This device includes a vertical feeding device and a horizontal peeling device, with four support pillars at the bottom. The feeding device includes a feeding housing, the bottom of which is connected to and communicates with the peeling device. A feeding port is located at the upper end of the housing, and a guide rod is installed inside the housing cavity. A drive motor connected to the guide rod is located on the top end of the housing, and a preheater is located on the side housing. The peeling device includes a peeling housing and a peeling mechanism. The peeling mechanism is connected to the drive motor via bearings. A dust suction hole and a discharge port are located at the bottom of the peeling housing. The dust suction hole penetrates the bottom of the peeling housing, and a V-shaped dust collection hood is located directly below the dust suction hole. A dust outlet connected to a vacuum cleaner is located at the bottom of the dust collection hood, and the vacuum cleaner is connected to a dust collection bag via a pipe. This invention can automatically peel labels off waste plastic bottles without manual processing, resulting in high work efficiency.

[0004] However, the aforementioned technologies primarily rely on the sharp teeth on the spiral blades to tear off the labels, and they cannot achieve precise timing control or multi-level collaborative operation. Specifically, traditional recycling equipment has the following significant shortcomings in structural design and process flow: Firstly, magnetic separation units often employ static arrangements or low-speed rotation structures, resulting in limited effective adsorption areas. As debris continuously passes through, the surface is easily covered and shielded by non-magnetic plastic fragments, creating a "shielding effect." This significantly reduces the ability to capture internal and deep metal impurities, leading to low and unstable rejection rates. Furthermore, the adsorption surface lacks an online cleaning mechanism, making it difficult to automatically remove accumulated metal shavings. Frequent shutdowns for manual handling are necessary, severely restricting the equipment's continuous operation efficiency and processing capacity. Secondly, existing peeling methods primarily attempt to remove labels through a single mechanical scraping method, a crude process. This method lacks a preheating and softening stage for the self-adhesive adhesive, as well as a vibration or tapping mechanism to initially loosen the label from the interface. It also lacks a subsequent deep friction peeling process, easily leaving adhesive residue on the plastic surface, severely affecting the purity and surface quality of the recycled plastic, and failing to meet the requirements of high-end recycling.

[0005] Based on the above-mentioned shortcomings, this application designs a recycling device for dismantling plastic products from waste household appliances. Summary of the Invention

[0028] In summary, this application includes the following beneficial technical effects:

[0029] 1. This invention integrates multiple functional units, including magnetic separation, hot air softening, vibration peeling, rolling friction, and air separation, into a compact continuous production line. Each unit achieves coordinated action and process connection through linkage devices. After the plastic fragments enter the inlet chamber via the conveyor line, they are attracted by magnetic components to remove mixed metal debris, thus achieving automated separation of metal impurities. Subsequently, the plastic fragments enter the softening device. Through the cooperation of the opening and closing plate and the partition, the plastic fragments can be intermittently softened with hot air to ensure that the labels are fully softened at high temperature to facilitate subsequent peeling. At the same time, the falling speed of the plastic fragments can be controlled to match the processing rhythm of the vibration peeling device and the rolling friction device, thereby performing multiple peeling operations and improving the cleanliness of the plastic fragments.

[0030] 2. This application further designs the structure of the magnetic suction component. Whenever the magnetic suction component comes into contact with the conveyor belt, the magnetic suction plate swings back and forth due to the squeezing method, thereby increasing the contact area with the plastic fragments and increasing the metal adsorption rate. Subsequently, when the magnetic suction plate passes through the wiping component, the metal impurities on the surface of the magnetic suction plate can be completely scraped into the recycling tank to prevent the metal impurities from remaining and affecting the subsequent adsorption effect.

[0031] 3. This application significantly improves the separation efficiency and cleanliness of labels and plastic fragments through a dual peeling mechanism of vibration separation device and rolling friction device. The vibration of the guide component, combined with the inclined structure of the guide component and the intermittent lifting and lowering of the separator, extends the conveying time and increases the number of vibrations while the plastic fragments are vibrated and conveyed obliquely downwards, thus improving the peeling effect. Subsequently, the electric drive roller of the rolling friction device drives the hard nylon brush to rotate at high speed, which rubs and washes the falling plastic fragments. The friction between the brush and the plastic fragments completely peels off the residual labels. Compared with a single vibration or friction method, the dual peeling mechanism can handle labels of different thicknesses and different adhesion strengths, ensuring more thorough label peeling from the surface of the plastic fragments and providing higher quality raw materials for subsequent plastic recycling.

[0032] 4. The linkage device set in this application, through the cooperation of the meshing component, the lifting component, and the extrusion frame, links the action of the softening device with the movement of the cleaning device. When the opening and closing plate in the softening device needs to be opened to release plastic fragments, the meshing component drives the connecting gear to rotate, while the lifting component controls the rotation of the partition to realize the switching of hot air delivery. During the lifting process, the extrusion frame will squeeze the extrusion column three of the cleaning device, pushing the collection frame to slide in the movable groove, so that the cleaning brush cleans the hard nylon brush of the rolling friction device, brushing off the label debris wrapped on the brush and blowing it into the collection frame through the airflow sprayed from the nozzle, avoiding the brush from being blocked and affecting the friction effect. This linkage design allows the equipment to automatically trigger the cleaning or preparation action of the next related component while completing one process action, reducing the idle time of the equipment and improving the overall processing efficiency.

[0047] The following is in conjunction with the appendix Figures 1 to 13 This application will be described in further detail.

[0048] This application discloses a recycling device for dismantling plastic products from waste household appliances. This application uses magnetic attraction, thermal softening, and multiple label peeling methods to remove metal particle impurities and labels from plastic fragments, thereby improving the purity of plastic fragments and laying a good foundation for subsequent recycling.

[0049] Reference Figures 1 to 5As shown in the figure, this embodiment discloses a recycling equipment for dismantling plastic products from waste household appliances, including a recycling bin 1, an entry bin 2, a conveyor line 21, a lifting device 22, an electric roller 23, a rotating roller 24, magnetic suction components 3, a collection device 4, a softening device 5, a vibration detachment device 6, a rolling friction device 7, a cleaning device 8, a linkage device 9, and an air separation device 10. The entry bin 2 is built at the right end of the recycling bin 1. The conveyor line 21 is located at the lower end of the entry bin 2. The lifting device 22 is located at the upper end of the entry bin 2. A rotatable electric roller 23 is located at the lower end of the lifting device 22. A rotating roller 24 is sleeved on the electric roller 23. Oscillable magnetic suction components 3 are evenly arranged along the circumference of the rotating roller 24. A collection device is used to clean the surface of the magnetic suction components 3. 4. The softening device 5 is installed in the upper part of the recycling bin 1. The softening device 5 is used to intermittently soften and transport plastic fragments with hot air. The vibration removal device 6 is installed in the middle of the recycling bin 1. The left and right vibration removal devices 6 vibrate to peel off the softened labels on the falling plastic fragments. The rolling friction device 7 is rotatably installed in the recycling bin 1. The left and right rolling friction devices 7 rub to peel off the softened labels on the falling plastic fragments. The cleaning device 8 for cleaning the rolling friction device 7 is slidably installed in the movable groove opened in the side wall of the recycling bin 1. The vibration removal device 6 and the cleaning device 8 are linked by a linkage device 9. The air separation device 10 is installed in the lower part of the recycling bin 1.

[0050] In the actual recycling process, the shredded plastic fragments are conveyed to the softening device 5 via the conveyor line 21. During the conveying process, the lifting device 22 drives the electric roller 23, rotating roller 24, and magnetic suction component 3 to descend to the working height. The electric roller 23 drives the rotating roller 24 and the annularly arranged magnetic suction component 3 to rotate. The rotating magnetic suction component 3 comes into contact with the conveyor line 21 and forms an oscillating operation, thereby gently turning and flipping the plastic on the conveyor line 21, while adsorbing and removing metal particles (the metal impurities adsorbed on the magnetic suction component 3 are subsequently collected and cleaned by the collection device 4). The plastic fragments with metal impurities removed fall onto the softening device 5, where the plastic fragments are softened at high temperature. The plastic fragments are intermittently conveyed downwards, heated to soften the adhesive, and then the softened labels are peeled off by vibration using the left and right arranged vibration detachment devices 6. The softened labels are then peeled off by friction using the left and right arranged rolling friction devices 7 (it should be noted that the cleaning device 8 in this application can clean the adhesive residue wiped off by the rolling friction devices 7). This separates the plastic fragments and labels. The peeled paper scraps and notes are then collected by air blowing using the air separation device 10. The clean plastic fragments fall normally. This application achieves efficient removal of metal impurities and labels from plastic fragments through the synergistic effect of magnetic attraction, thermal softening, vibration peeling, rolling friction, and air separation.

[0051] Reference Figure 4 As shown, in order to extend the life of the elasticity in the magnetic suction component 3, this application uses a lifting device 22 to drive the electric roller 23, the rotating roller 24, and the magnetic suction component 3 to lift. The specific structure of the lifting device 22 is as follows: the lifting device 22 includes a connecting frame 221, an electric push rod 222 is connected between the connecting frame 221 and the entry chamber 2, and a rotatable electric roller 23 is provided inside the connecting frame 221.

[0052] In actual operation, when not magnetically attracted, the electric push rod 222 drives the connecting frame 221, electric roller 23, rotating roller 24, and magnetic attractor 3 to rise, so that the magnetic attractor 3 in the lower area is away from the conveyor belt area of ​​the conveyor line 21. When magnetic attraction is performed later, the electric push rod 222 drives the connecting frame 221, electric roller 23, rotating roller 24, and magnetic attractor 3 to fall to the working area.

[0053] Reference Figures 6 to 8As shown, since the magnetic suction surface of the magnetic suction plate 35 is parallel to the material inlet direction in the initial state, the current state ensures the cleanliness of the metal particles scraped off the magnetic suction surface by the subsequent wiping component 42. When this state has a small contact area with the incoming plastic fragments, it cannot cover and magnetically attract the metal particle impurities of the plastic fragments. This application sets the magnetic suction plate 35 to a swingable working state, thereby increasing the magnetic suction area. The specific structure of the magnetic suction component 3 is as follows: the magnetic suction component 3 includes a spring telescopic rod 31, a connector 32, and a rotating... The components include: moving part 33, torque spring 34, magnetic suction plate 35, high-position rod 36, extrusion column one 37, extrusion head one 371, low-position rod 38, extrusion column two 39, and extrusion head two 391. One end of the spring telescopic rod 31 is connected to the built-in groove. The rotating roller 24 has built-in grooves evenly distributed along its circumference. The other end of the spring telescopic rod 31 is connected to the connector 32. The connector 32 and the rotating part 33 are rotatably connected, and a torque spring 34 is connected between the connector 32 and the rotating part 33. The magnetic suction plate 35 is installed on the rotating part 33. On component 33, a high-position rod 36 is installed on one side of the upper end of the rotating component 33. An extrusion column 37 is installed on the upper side wall of the high-position rod 36. An extrusion head 371, which is used to extrude and cooperate with the extrusion column 37, is installed in the built-in groove. A low-position rod 38 is installed on the other side of the upper end of the rotating component 33. There is a height difference between the high-position rod 36 and the low-position rod 38. An extrusion column 39 is installed on the upper side wall of the low-position rod 38. When the extrusion head 371 and the extrusion column 37 come into contact, they will force the rotating component 33 and the magnetic suction plate 35 to rotate by extrusion. After the two separate, the magnetic suction plate 35 rotates back to the initial angle under the action of the torque spring 34. When the extrusion column 39 and the extrusion head 391 come into contact, the rotating part 33 and the magnetic suction plate 35 are forced to rotate in opposite directions. The extrusion head 391, which is used in conjunction with the extrusion column 39, is installed in the built-in groove. A support plate is set in the chamber 2. The support plate provides bottom support for the upper area of ​​the conveyor belt in the conveyor line 21, which avoids the situation where the conveyor belt is subjected to pressure and forms a concave downward pressure when the magnetic suction part 3 comes into contact with the conveyor belt.

[0054] In the actual magnetic process, the electric roller 23 drives the rotating roller 24 and the magnetic accumulator 3 to rotate circumferentially. As the magnetic accumulator 3 gradually approaches the conveyor belt, the lower part of the magnetic accumulator 35 in this application will be squeezed and retracted upward into the built-in groove. During the retraction process, the first extrusion head 371 and the second extrusion head 391 will successively squeeze the first extrusion column 37 and the second extrusion column 39, respectively, so that the magnetic accumulator 35 and the rotating component 33 rotate horizontally relative to the connecting head 32, so that the magnetic accumulator 35 is in a swinging state, which increases the contact area between the magnetic accumulator 35 and the plastic fragments in contact. As the magnetic accumulator 3 gradually moves away from the conveyor belt (not completely separated), the lower part of the magnetic accumulator 35 gradually extends out of the built-in groove under the elasticity of the spring telescopic rod 31. At this time, the first extrusion head 371 and the second extrusion head 391 can still squeeze the first extrusion column 37 and the second extrusion column 39, respectively, so that the magnetic accumulator 35 rotates horizontally in the opposite direction. Through the reciprocating small amplitude swing of the magnetic accumulator 35, the magnetic attraction effect is improved.

[0055] Reference Figure 6 As shown, the collection device 4 includes a guide frame 41, which is installed inside the recycling bin 1. Wiping components 42 are evenly arranged from front to back on the right end of the guide frame 41. The bottom of the guide groove opened inside the guide frame 41 gradually decreases from back to front. An output frame 43 is connected to the front end of the guide frame 41.

[0056] Reference Figure 6 As shown, the wiping assembly 42 consists of two wiping pieces 421. The wiping pieces 421 have a recycling groove 422 with an open top inside, and the distance between the two wiping pieces 421 is equal to the thickness of the magnetic plate 35.

[0057] During the actual wiping process, the magnetic suction plate 35 in a swinging state magnetically separates the metal particles and impurities in the plastic fragments. The magnetic suction plate 35 with metal impurities adsorbed on its surface continues to move. When it enters between the two wiping members 421, the wiping members 421 scrape off the gold impurities on the magnetic surface of the magnetic suction plate 35. The scraped metal particles enter the recycling tank 422, and then enter the output frame 43 through the guide groove, and finally exit from the lower outlet position of the output frame 43.

[0058] Reference Figure 5 , Figure 9 , Figure 10As shown, the softening device 5 includes an opening and closing plate 51, a rotating shaft 52, a connecting gear 53, a partition 54, a rotating column 55, an I-beam wheel 56, a conveyor belt 57, and an air supply assembly 58. The left end of the opening and closing plate 51 is connected to the rotating shaft 52, which is connected to the recovery chamber 1 via a bearing. The front end of the rotating shaft 52 is equipped with a connecting gear 53. The partition 54 has rotating columns 55 symmetrically arranged at both ends, which are connected to the recovery chamber 1 via bearings. The rotating column 55 located at the front is connected to the I-beam wheel 56, and a conveyor belt 57 connects the I-beam wheels 56. The air supply assembly 58 is located at the back of the recovery chamber 1, and the upper end of the air supply assembly 58 is connected to the rotating column at the rear. The column 55 forms a sealed rotation. It should be noted that the glass transition temperature (the temperature at which it begins to soften) and heat distortion temperature of common household appliance plastics (such as ABS, PP, PS) are generally much higher than 80-120℃. The "high temperature" and "hot air" mentioned in this application refer to the temperature for a short period of time, not the "actual temperature reached by the plastic". The plastic fragments stay in the softening device 5 for a very short time, which is an instantaneous heating. It is difficult for the internal temperature to rise evenly to the temperature of the surface hot air. More importantly, the softening point of self-adhesive is usually very low. It becomes noticeably sticky at 60-80℃, while plastics require higher temperatures to soften and deform significantly. Therefore, the high temperature in this application will not cause the plastic fragments to melt and soften.

[0059] Reference Figure 9 , Figure 10 As shown, the upper end of the partition 54 is provided with a spray hole, the middle part of the rotating column 55 located at the rear side is provided with a cavity 551, the lower rear end of the cavity 551 is provided with a connecting interface 552, and the cavity 551 is connected to the connecting cavity 541 opened inside the partition 54.

[0060] Reference Figure 5 As shown, the gas delivery assembly 58 includes a diversion frame 581, which is located on the outer wall of the recovery chamber 1. The diversion frame 581 and the output frame 582 are connected to the air pump 583 via a connecting pipe. The air pump 583 is mounted on the recovery chamber 1 via a base. The upper end of the diversion frame 581 is connected to the connector 584 via a straight pipe. The rotating column 55 located at the rear is connected to the connector 584 in a sealed rotating connection. The connector 552 at the initial angle is aligned with the straight pipe. When the partition 54 is in a horizontal state, a sealed horizontal structure is formed between the partitions 54, thereby temporarily holding the plastic fragments that fall into this area. At this time, the connector 552 is aligned with the straight pipe, and the nozzle is in an open state (the nozzle 83 is in a closed state). The air pump 583 outputs hot air upward from the nozzle. The plastic fragments are turned over and softened by the hot air blowing below.

[0061] In the actual softening process, when the opening and closing plate 51 is in the open state, a certain amount of plastic fragments fall onto the closed partition 54. At this time, hot air is used to heat the plastic fragments to soften the adhesive. After softening, the opening and closing plate 51 is rotated counterclockwise by the meshing operation of the linkage device 9 to form a sealed state. Subsequently, the plastic fragments input from the conveyor line 21 will fall onto the opening and closing plate 51. After sealing, the partition 54 rotates ninety degrees, causing the softened plastic fragments to fall.

[0062] Reference Figure 11 As shown, in order to improve the peeling effect, this application uses a vibration peeling device 6 to vibrately peel off the label on the surface of the plastic fragment. The specific structure is as follows: the vibration peeling device 6 includes a fixed base 61, a guide plate 62, a partition mechanism 63, a vibration mechanism 64, and a drive mechanism 65. The fixed base 61 is installed on the inner wall of the recycling bin 1. A vibrating guide plate 62 is slidably arranged on the upper end of the fixed base 61. A partition mechanism 63 is arranged in the fixed base 61. The partition mechanism 63 performs a cavity-blocking operation on the upper end of the guide plate 62. A vibration mechanism 64 is arranged on the inner side of the fixed base 61. The guide plate 62, the partition mechanism 63, and the vibration mechanism 64 are linked and cooperated through the drive mechanism 65.

[0063] Reference Figure 11 As shown, the guide plate 62 includes a guide member 621. The lower end of the inclined guide member 621 is provided with a sliding block 622. The sliding block 622 is slidably mounted on the fixed base 61. The lower end of the guide member 621 is provided with a vibration rod 623.

[0064] Reference Figure 11 As shown, the partition mechanism 63 includes a partition member 631. The fixed base 61 has an internal groove. The partition member 631 is slidably disposed in the internal groove. The upper surfaces of the partition members 631 arranged from left to right are set with one high and one low, thereby extending the conveying time. The lower end of the partition member 631 is used in a pressing fit with the cam 632. The cam 632 is mounted on the rotating shaft 633. The end of the rotating shaft 633 is connected to the internal groove through a bearing. A large gear 634 is fixedly sleeved on the rotating shaft 633.

[0065] Reference Figure 11 As shown, the vibration mechanism 64 includes a vibration head 641, which is mounted on a movable rod 642. The movable rod 642 is slidably disposed in the built-in groove. The lower end of the movable rod 642 is connected to the built-in groove through a connecting spring. The connecting spring always maintains an upward pushing tendency on the movable rod 642. A pressing rod 643 is installed on the upper end of the movable rod 642. The upper inclined surface of the vibration head 641 has a structure that gradually slopes downward from the outside to the inside.

[0066] Reference Figure 11 As shown, the drive mechanism 65 includes a motor 651, which is connected to the built-in slot via a motor mount. One end of the motor 651 is connected to a connecting shaft 652, and the other end of the connecting shaft 652 is connected to the built-in slot via a bearing. From the outside to the inside, the connecting shaft 652 is sequentially equipped with a small gear 653, a first extrusion wheel 654, and a second extrusion wheel 655. A large gear 634 meshes with the small gear 653. The first extrusion wheel 654 is used in a pressing fit with the extrusion rod 643, and the second extrusion wheel 655 is used in a pressing fit with the vibration rod 623.

[0067] During actual vibration, the plastic fragments after the self-adhesive adhesive has melted fall onto the guide component 621. The motor 651 drives the connecting shaft 652 to rotate at high speed, and the small gear 653, extrusion roller 1 654, and extrusion roller 2 655 connected to the connecting shaft 652 rotate synchronously. The speed difference between the small gear 653 and the large gear 634 reduces the rotational speed of the rotating shaft 633. Based on the cam principle, the cam 632 on the rotating shaft 633 presses against the separator 631, thus achieving low-speed lifting and lowering, thereby intermittently separating the vibrating separator 631 and extending the time for the plastic fragments to be conveyed obliquely downwards on the separator 631. Through extrusion... The squeezing between the pressure roller 655 and the vibrating rod 623, along with the cam principle, causes the guide member 621 to vibrate. Combined with the inclined structure of the guide member 621 and the intermittently lifting and lowering separator 631, the plastic fragments are conveyed obliquely downwards while the conveying time is extended, the number of vibrations is increased, and the peeling effect is improved. The plastic fragments discharged from the guide member 621 fall onto the vibrating head 641. Through the squeezing between the pressure roller 654 and the pressure rod 643, and the cam principle, the vibrating head 641 is in a left-right vibration operation, so that the left-right arranged vibrating heads 641 further vibrate and peel off the falling plastic fragments.

[0068] Reference Figure 4 As shown, the rolling friction device 7 includes an electrically driven roller 71, and hard nylon brushes 72 are uniformly arranged on the surface of the electrically driven roller 71 along its circumference.

[0069] Reference Figure 12 As shown, the cleaning device 8 includes a collection frame 81, which is horizontally slidably disposed in a movable groove opened in the side wall of the recycling bin 1. A cleaning brush 82 is disposed in the middle of the inside of the collection frame 81, and a nozzle 83 is disposed at the lower end of the collection frame 81. A docking hole 84 corresponding to the position of the nozzle 83 is opened in the interlayer of the recycling bin 1. The rear end of the docking hole 84 is connected to the output frame 582 through a connecting pipe 85. A squeezing column 86 is disposed at the front end of the collection frame 81, and a return spring 87 is connected between the squeezing column 86 and the recycling bin 1.

[0070] In the actual friction peeling process, the electric drive roller 71 drives the rigid nylon brush 72 to rotate, and the left and right electric drive rollers 71 rotate in opposite directions with a speed difference between them. During the rotation, the strong friction of the rigid nylon brush 72 peels the softened label paper and adhesive tape from the plastic surface. At this time, some label paper and adhesive will be rubbed onto the rigid nylon brush 72. As the working time increases, the amount of label paper and adhesive on the rigid nylon brush 72 may increase. Therefore, this application... Please clean the rigid nylon brush 72 using the cleaning device 8. Specifically, the extrusion column 86 is squeezed by the descending extrusion frame 94, causing the collection frame 81 to move inward. At this time, the nozzle 83 is aligned with the docking hole 84. The hot air sprayed from the nozzle 83 applies high temperature to the rigid nylon brush 72, causing the adhesive on its surface to soften a second time. The cleaning brush 82, which moves inward, scrapes off the label and adhesive from the surface of the rigid nylon brush 72. The cleaning brush 82 can be removed and cleaned or replaced periodically.

[0071] Reference Figure 3 , Figure 13 As shown, the linkage device 9 includes a meshing component 91, which is slidably mounted on the back of the recycling bin 1. The meshing component 91 meshes with the connecting gear 53 and is connected to the extended end of the electric push rod 92, which is mounted on the back of the recycling bin 1. A lifting component 93 is provided at the lower end of the meshing component 91. The lifting of the lifting component 93 can control the rotation of the partition 54. A compression frame 94 is symmetrically mounted on the left and right sides at the lower end of the lifting component 93. The compression frame 94 and the compression column 86 are used for compression cooperation.

[0072] In actual linkage process, this application uses electric push rod 92 to drive the meshing component 91, lifting component 93 and extrusion frame 94 to lift and lower, thereby controlling the internal structure of vibration detachment device 6 and cleaning device 8.

[0073] Reference Figure 13 As shown, this application controls the rotation angle of the guide plate 62 and the partition mechanism 63 through the meshing component 91 and the lifting component 93. The specific structure is as follows: the meshing component 91 includes an L-shaped frame 911. The upper end of the L-shaped frame 911 is slidably connected to the rack frame 912. The rack frame 912 meshes with the connecting gear 53. The upper end of the L-shaped frame 911 has an inner groove. An extrusion block 913 is slidably connected in the inner groove. A through groove is opened on one side of the rack frame 912. A snap-fit ​​block 914 is horizontally slidably arranged in the through groove. The inner half of the snap-fit ​​block 914 in the initial position is snapped into the inner groove. A limiting plate 915 that limits the outer side of the snap-fit ​​block 914 is fixedly installed on the outer wall of the recycling bin 1. An embedded groove 916 is opened on the inner side of the lower end of the limiting plate 915. The upper slope of the embedded groove 916 gradually slopes upward from the outside to the inside.

[0074] Reference Figure 3 As shown, the lifting assembly 93 includes a connecting rod 931. The upper end of the inverted T-shaped connecting rod 931 is connected to the L-shaped frame 911. The lower end of the connecting rod 931 is slidably disposed in the sliding groove opened at the upper end of the U-shaped frame 932. A rack 933 is provided on the inner side wall of the U-shaped frame 932. The rack 933 meshes with the working gear 934. The working gear 934 is mounted on the rotating column 55 located at the front side.

[0075] During actual adjustment, when the meshing assembly 91 and lifting assembly 93 are not lowered, the opening and closing plate 51 is in an open state, and the partition 54 is in a horizontal state. At this time, the plastic fragments fall onto the partition 54, and the interface 552 and the straight pipe are aligned. The air pump 583 blows hot air through the cavity 551 of the diverter frame 581, the straight pipe, the interface 584, the rotating column 55 at the rear end, and the connecting cavity 541, and then sprays it out of the nozzle for hot air and high-temperature softening (at this time, due to the misalignment between the nozzle 83 and the docking hole 84, the nozzle 83 is in a blocked state, and the hot air cannot be sprayed out from the nozzle 83). After the adhesive in the single batch of plastic fragments is softened, the electric push rod 92 drives the meshing assembly 91 and lifting assembly 93 to lower. During the lowering process, the L-shaped frame 911 and the rack frame 912 lower synchronously (the two temporarily lower each other). (Locked), the return frame 932 does not descend temporarily. The opening and closing plate 51 is controlled to rotate counterclockwise until a closed state is formed by the meshing of the descending rack frame 912 and the connecting gear 53 (the plastic fragments that fall later will be temporarily left on the partition 54). At this time, the snap block 914 enters the inner groove 916 under the elastic push of the extrusion block 913. The height of the rack frame 912 remains unchanged. The L-shaped frame 911 continues to descend, thereby driving the return frame 932 to begin to descend. The rotation of the single I-beam wheel 56 is controlled by the meshing between the rack 933 and the working gear 934. Under the action of the conveyor belt 57, the entire set of partitions 54 is driven to rotate until the rotation angle is ninety degrees. At this time, the descent is completed, and the rotating interface 552 is misaligned with the straight pipe. At this time, the hot air cannot be ejected from the ejection hole (hot air stops).

[0076] Reference Figure 3 As shown, the lower inclined portion of the extrusion frame 94 has a structure that gradually tilts outward from top to bottom, and the inclined portion of the extrusion frame 94 forms an extrusion state with the extrusion column 86. The middle part of the extrusion frame 94 is an open groove, and the fixing block 95, which is slidably disposed in the open groove, is fixedly installed in the recycling bin 1, and the fixing block 95 and the open groove are elastically connected.

[0077] When the extrusion frame 94 is not lowered, the collection frame 81 is in the outermost position under the action of the return spring 87. At this time, the nozzle 83 and the docking hole 84 are misaligned, the nozzle 83 is in a blocked state, and hot air cannot be sprayed out from the nozzle 83. At this time, the outermost cleaning device 8 is in a closed state. After the extrusion frame 94 is lowered, the extrusion column 86 is squeezed, causing the collection frame 81 to move inward. At this time, the nozzle 83 and the docking hole 84 are aligned. The hot air sprayed from the nozzle 83 applies high temperature to the hard nylon brush 72, causing the self-adhesive on its surface to soften for a second time. The label paper and adhesive on the surface of the hard nylon brush 72 are scraped off by the inwardly moving cleaning brush 82.

[0078] Reference Figure 4 As shown, the air separation device 10 includes a storage frame 101, which is slidably disposed in the inflow groove 102 opened on the lower left side of the recycling bin 1. A filter screen is provided in the upper half of the right end of the inflow groove 102. An air separation pump 103 is installed on the lower right side of the recycling bin 1, and the air inlet of the air separation pump 103 faces to the left.

[0079] In the actual air separation process, the air separation pump 103 performs air separation on the falling plastic fragments and labels. Because the labels are light and small, they will pass through the filter screen and enter the collection box 101, while the plastic fragments fall normally.

[0080] Working principle:

[0081] Step 1: The shredded plastic fragments are conveyed to the softening device 5 via the conveyor line 21. During the conveying process, the plastic fragments on the conveyor line 21 are gently turned and flipped by the oscillating magnetic suction device 3, while the metal particles in them are adsorbed and sucked out.

[0082] Step 2: The plastic fragments with metal impurities removed fall onto the softening device 5. The softening device 5 softens the plastic fragments at high temperature and intermittently conveys them downwards, heating the adhesive to soften it.

[0083] Step 3: The softened labels on the falling plastic fragments are peeled off by vibration using the left and right arranged vibration detachment devices 6, and the softened labels on the falling plastic fragments are peeled off by friction using the left and right arranged rolling friction devices 7.

[0084] Step 4: The paper scraps and sticky notes that have been peeled off are collected by air blowing through the air separation device 10, while the clean plastic fragments fall normally.

[0085] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
