Description

Technical Field

[0001] This invention relates to the field of plastic recycling equipment technology, specifically to a crushing and processing equipment for recycling plastic waste from shoe soles. Background Technology

[0002] In the waste shoe sole plastic recycling and processing industry, the crushing process is a key link connecting pre-processing and post-granulation. Currently, most common waste plastic crushing equipment on the market adopts a roller or toothed disc crushing structure. Its working principle mainly relies on two sets of relatively rotating crushing toothed discs to bite and tear the material.

[0003] The inventors have discovered at least the following problems in the prior art: In existing equipment, during the crushing of elastic plastic shoe soles by a crushing disc, some material gets squeezed and stuck between the teeth of the disc. The elastic material is difficult to detach on its own after being squeezed, and the accumulation of material in the tooth gaps reduces the meshing space of the disc and reduces the crushing capacity. Equipment on the market that only has a single fixed scraper block has no reverse linkage between the scraper block and the disc, and can only simply lift a small amount of material. In addition, plastic fragments will also be left in the gaps of the scraper block itself. The continuous accumulation of material in both the disc and the scraper block will increase the operating load of the equipment and require frequent shutdowns for manual cleaning. The existing equipment has a simple open hopper without separation or guiding structures, which causes the shoe soles to fall in whole pieces. At the same time, without a restraint structure to correct the feeding posture of the shoe soles, the shoe soles often enter the meshing gap between the two sets of crushing discs laterally and at an angle. The discs have difficulty in stably gripping the material, which limits the feeding speed. In addition, the sticky material continues to accumulate inside the hopper, which is prone to blockage. Operators need to stop the machine regularly to manually clear the blockage, which affects the continuous processing efficiency. The crushed plastic scraps fall vertically and accumulate in a localized area of ​​the magnetic separator. The material pile is quite thick, and the metal impurities mixed in the bottom layer cannot fully contact the magnetic separator working surface, resulting in incomplete separation of the metal impurities. Furthermore, the lack of a dynamic material distribution and oscillating guiding structure that is linked with the crushing and cleaning mechanism means that the material falls within a fixed range, and the entire working surface of the magnetic separator cannot be utilized.

[0004] Therefore, this solution provides a crushing and processing equipment for recycling plastic waste from shoe soles to solve the above problems. Summary of the Invention

[0005] In view of the problems in the existing technology, such as easy material sticking and clogging during feeding, inability to self-clean material accumulation in the gaps of the toothed disc, and insufficient magnetic separation and impurity removal due to concentrated accumulation of discharged material, the present invention provides a crushing and processing equipment for recycling plastic waste from shoe soles to solve the above problems.

[0012] Preferably: a sliding frame that slides left and right is arranged inside the material distributing box, both the first auxiliary slider and the second auxiliary slider are fixedly connected above the sliding frame through the limit sliders at the bottom, a connecting slider is fixedly connected to one side of the sliding frame, the connecting slider is slidably connected inside the material distributing box, two special-shaped sliders are fixedly connected below the connecting slider, and the special-shaped sliders are provided with special-shaped grooves.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In the present invention, by providing a processing mechanism matched with the crushing mechanism, the hydraulic cylinder outputs power to drive the first side plate to move, the transmission slider, the transmission gear and the linkage slider form a reverse transmission structure, so the first side plate and the second side plate can perform synchronous reverse lifting; when the first processing block on the first side plate and the second processing block on the second side plate move upward alternately, the elastic plastic waste stuck in the gap of the main crushing toothed disc and the gap of the auxiliary crushing toothed disc can be pushed upward, and the pushed material will re-fall into the meshing area of the two sets of toothed discs to complete crushing; when the first processing block and the second processing block move downward, they can carry away the material stuck in the gaps between their adjacent blocks, which can not only clean the residual material in the gaps of the toothed discs, but also clean the material stuck in the gaps of the processing blocks themselves, so that no plastic waste will be retained in the gaps of the toothed discs and the processing blocks for a long time.

[0017] This invention utilizes the cooperation between the material guiding mechanism and the processing mechanism. The first and second combing strips are made of elastic metal and are arranged at different heights to form multiple guide grooves. After the waste shoe soles fall into the hopper, they will bounce upon contact with the combing strips, separating the shoe soles that are stuck together. At the same time, the guide grooves can constrain the posture of the shoe soles, causing them to fall into the meshing area of ​​the two sets of toothed discs at an angle perpendicular to the main crushing toothed disc and the auxiliary crushing toothed disc, increasing the amount of material grabbed by the toothed discs. When the first and second side plates move up and down alternately, the connecting rack, linkage gear, and eccentric wheel can drive the receiving plate and unit plate to alternately slide up and down at high frequency. The two sets of combing strips can alternately complete two types of actions: material rebound separation and material orientation guidance, reducing the frequency of material accumulation and blockage inside the hopper.

[0018] This invention utilizes an auxiliary mechanism with guide arc blocks fixed on base plate one and base plate two to fill the gaps between the main crushing disc and side plate one, and between the auxiliary crushing disc and side plate two, preventing small-sized crushed materials from leaking directly through the gaps on the sides of the discs. When the processing block moves downward, it pushes auxiliary slider one and auxiliary slider two closer to the corresponding crushing discs. The protruding teeth on the side of the auxiliary sliders fit against the outer edge of the discs, pushing stubborn waste materials stuck in the gaps of the discs to the working surface of the discs for secondary crushing. The limiting slider at the bottom of the auxiliary sliders is equipped with a spring structure. After the processing block is lifted upward and loses its pushing force, the spring can pull the auxiliary sliders to automatically reset. The sliding distance of the auxiliary sliders can be kept fixed, continuously cooperating with the crushing discs to clean up residual materials and reduce raw material loss caused by the direct discharge of insufficiently crushed materials.

[0019] This invention utilizes the coordinated operation of a processing mechanism, an auxiliary mechanism, and a material distribution mechanism. The auxiliary slider is fixedly connected to the sliding frame. When the auxiliary slider slides horizontally in sync, it drives the sliding frame and the connecting slider to move synchronously along the inside of the material distribution box. The multi-component material strips on the side of the connecting slider move horizontally in sync with the frame, which can dynamically disperse the crushed material falling onto the surface of the guide plate, preventing the material from accumulating in a localized area of ​​the guide plate. When the connecting slider moves horizontally, it drives the irregularly shaped slider to move synchronously. The wavy groove inside the irregularly shaped slider can convert the horizontal displacement of the slider into the up-and-down reciprocating movement of the limiting rod and the connecting slider. After being driven by connecting rod two and connecting rod one, the connecting slider drives the guide plate to continuously swing back and forth, thus widening the material falling and spreading range. The crushed material can be dispersed to the entire working surface of the magnetic separation component inside the discharge box. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Example: Please refer to Figures 1-12 The above describes a crushing and processing equipment for recycling plastic waste from shoe soles. It includes a frame mechanism 1, which includes a feeding hopper 11, a crushing box side plate 12, a crushing box side plate 13, and a support plate 14 distributed from top to bottom. A material guiding mechanism 5 is provided on the inner side of the feeding hopper 11, a crushing mechanism 4 and a processing mechanism 6 are provided on the inner side of the crushing box side plate 12, and an auxiliary mechanism 7 and a material distribution mechanism 8 are provided on the inner side of the support plate 14. The material guiding mechanism 5 includes a receiving plate 51 and a unit plate 52 that are symmetrical and identical on the left and right sides. The receiving plate 51 and the unit plate 52 are slidably connected to the inner side of the feeding hopper 11. The processing mechanism 6 includes a side plate 62 and a side plate 63 that are slidably connected to the inside of the side plate 13 of the crushing box. A processing block 64 is fixedly connected to one side of the side plate 62, and a processing block 65 is fixedly connected to one side of the side plate 63. The auxiliary mechanism 7 includes two symmetrical base plates 71 and 72. Auxiliary sliders 74 and 75 are evenly arranged on the top of the base plates 71 and 72, respectively. The material distribution mechanism 8 includes a material distribution box 81, a guide plate 87, and multiple material distribution strips 86 above the guide plate 87; The frame mechanism 1 is equipped with an external controller that can control the operation of other equipment.

[0024] In this embodiment, the crushing mechanism 4 includes a main crushing toothed disc 42 and an auxiliary crushing toothed disc 43 that are evenly arranged. The crushing mechanism 4 also includes a drive motor 41 installed above the support plate 14, and the output end of the drive motor 41 is connected to the main crushing toothed disc 42. Among them, the main crushing toothed disc 42 and the auxiliary crushing toothed disc 43 both refer to a single crushing disc with a toothed structure on its surface. In addition, the main crushing toothed disc 42 is installed on the periphery of the drive shaft. One end of the drive shaft is connected to the output end of the drive motor 41 via a belt, and the other end of the drive shaft drives the central shaft of the auxiliary crushing toothed disc 43 via a gear set, thereby enabling the main crushing toothed disc 42 and the auxiliary crushing toothed disc 43 to rotate in opposite directions. This is the existing core component of crushing and processing, namely the crushing mechanism 4, the frame mechanism 1, the magnetic separation component 2, and the conveying component 3, which together constitute the existing crushing equipment for recycling waste plastic shoe soles.

[0025] In this embodiment, multiple combing strips 53 and 54 are fixedly connected to the side of the receiving plate 51 and the unit plate 52 that are close to each other. The combing strips 53 and 54 are staggered. The receiving plate 51 and the unit plate 52 that are far apart from each other are fixedly connected to the receiving slider 55. A linkage shaft 56 is provided below the receiving slider 55. Among them, combing strip 1 53 and combing strip 2 54 are both made of elastic metal. Their lower ends are aligned between the secondary crushing tooth disk 43 and the main crushing tooth disk 42, which can guide the shoe sole to the biting area of ​​the main crushing tooth disk 42 and the secondary crushing tooth disk 43. Combing strip 1 53 and combing strip 2 54 have a height difference, which forms a guide groove between them, allowing the shoe sole to slide downward perpendicular to the main crushing tooth disk 42, thus making the crushing more stable. Combing strip 1 53 and combing strip 2 54 on the same side of unit plate 52 and receiving plate 51 form a similar trumpet shape.

[0026] In this embodiment, the outer periphery of the linkage shaft 56 is fixedly connected with eccentric wheels 57 evenly distributed, the outer periphery of the eccentric wheels 57 is in contact with the receiving slider 55, the two ends of the linkage shaft 56 are fixedly connected with linkage gears 58, the receiving slider 55 is slidably connected to the inner wall of the feeding hopper 11, and the linkage shaft 56, eccentric wheels 57 and linkage gears 58 are all rotatably connected to the inside of the feeding hopper 11. During the upward movement of the side plate 62, the receiving plate 51 is forced to reciprocate at high speed, while the unit plate 52 will not move. At this time, the combing strips 53 and 54 on one side of the receiving plate 51 are concentrated to rebound onto the sole, and the combing strips 53 and 54 on one side of the unit plate 52 are concentrated to guide the material, thereby avoiding blockage. The two processes alternate and are linked with the processing mechanism 6.

[0027] In this embodiment, multiple processing blocks 64 and auxiliary sliders 75 are located at the gaps between multiple secondary crushing discs 43, and multiple processing blocks 65 and auxiliary sliders 74 are located at the gaps between multiple main crushing discs 42. Connecting racks 68 and 69 are fixedly connected above side plates 62 and 63, respectively. Transmission sliders 66 and linkage sliders 67 are fixedly connected to both sides of side plates 62 and 63, respectively. Transmission gears 691 are engaged between transmission sliders 66 and linkage sliders 67. Transmission sliders 66, linkage sliders 67 and transmission gears 691 are all movably connected inside the side plate 12 of the crushing box. Connecting racks 68 and 69 are slidably connected inside the feeding hopper 11 and engaged with linkage gears 58. Among them, the upper ends of processing block 1 64 and processing block 2 65 are inclined surfaces to lift the residual material, while the lower ends are rounded corners to push the corresponding auxiliary slider 2 75 or auxiliary slider 1 74 to move. The transmission slider 66 and the linkage slider 67 are centrally symmetrical, with the transmission gear 691 as the center of symmetry. Both the transmission slider 66 and the linkage slider 67 are composed of a connecting plate and a rack. Thus, when the side plate 62 moves upward, the side plate 63 moves downward, and vice versa. Processing block 1 64, auxiliary slider 2 75 and main crushing toothed disc 42 are in the same vertical plane, and processing block 2 65, auxiliary slider 1 74 and auxiliary crushing toothed disc 43 are in the same vertical plane. Thus, the material guiding mechanism 5, auxiliary mechanism 7 and material distribution mechanism 8 can be linked during the alternating up and down movement of side plate 1 62 and side plate 2 63.

[0028] In this embodiment, both base plate 1 71 and base plate 2 72 are fixedly connected above the material distribution box 81. Both base plate 1 71 and base plate 2 72 are fixedly connected above each other with uniformly arranged guide arc blocks 73. The guide arc blocks 73 are located at the gap between the main crushing tooth disk 42 and the auxiliary crushing tooth disk 43. Auxiliary slider 1 74 and auxiliary slider 2 75 are located at the gap between the guide arc blocks 73. Both auxiliary slider 1 74 and auxiliary slider 2 75 are fixedly connected below each other with limit sliders 76. Each limit slider 76 is provided with a spring 77 on one side. The limit slider 76 is slidably connected to the inside of base plate 1 71 and base plate 2 72. Both auxiliary slider 1 74 and auxiliary slider 2 75 are provided with protruding teeth 78 on the side where they approach each other. The protruding teeth 78 cooperate with the main crushing tooth disk 42 or the auxiliary crushing tooth disk 43. Among them, the guide arc block 73 on the base plate 1 71 is used to fill the gap between the main crushing tooth disk 42 and the side plate 1 62, and similarly, the guide arc block 73 on the base plate 2 72 is used to fill the gap between the auxiliary crushing tooth disk 43 and the side plate 2 63. When processing block 1 64 moves down, auxiliary slider 2 75 can move closer to the main crushing tooth disk 42. When processing block 2 65 moves down, auxiliary slider 1 74 moves closer to the secondary crushing tooth disk 43. The opposite sides of auxiliary slider 1 74 and auxiliary slider 2 75 are inclined surfaces, which can be used to cooperate with processing block 2 65 and processing block 1 64, while the opposite sides are curved surfaces. These curved surfaces fit the outer periphery of the main crushing tooth disk 42 and the auxiliary crushing tooth disk 43. Similarly, the protruding teeth 78 also fit, so that when the residual material is in the protruding teeth 78 at auxiliary slider 2 75, the main crushing tooth disk 42 will perform secondary crushing on the material.

[0029] In this embodiment, the inside of the material distribution box 81 is provided with a sliding frame 82 that can slide left and right. Auxiliary slider 1 74 and auxiliary slider 2 75 are both fixedly connected to the top of the sliding frame 82 through the bottom limiting slider 76. A connecting slider 83 is fixedly connected to one side of the sliding frame 82. The connecting slider 83 is slidably connected to the inside of the material distribution box 81. Two irregular sliders 84 are fixedly connected to the bottom of the connecting slider 83. The irregular sliders 84 are provided with irregular grooves 85. The base plate 71 and the base plate 72 are each provided with a sliding groove for the auxiliary slider 74 and the auxiliary slider 75 to slide, and the spring 77 is located in the sliding groove. Since the processing block 64 and the processing block 65 move up and down alternately, the spring 77 rebounds the auxiliary slider 74 and the auxiliary slider 75, so that the distance between the auxiliary slider 74 and the auxiliary slider 75 is always fixed, thereby making the sliding range of the auxiliary slider 74, the auxiliary slider 75 and the sliding frame 82 consistent.

[0030] In this embodiment, one end of the guide plate 87 is rotatably connected to the inner side of the distribution box 81, and a connecting rod 88 is rotatably connected to the lower part of the guide plate 87. The other end of the connecting rod 88 is rotatably connected to the inner wall of the distribution box 81. A connecting rod 89 is rotatably connected to the upper part of the connecting rod 88. A connecting slider 891 is rotatably connected to the upper end of the connecting rod 89. The connecting slider 891 is slidably connected to the inner wall of the distribution box 81. A limit rod 892 is fixedly connected to one side of the connecting slider 891. The connecting slider 891 is located inside the irregular groove 85. Among them, the irregular slider 84 is inverted T-shaped and the irregular groove 85 is wavy. Therefore, during the sliding of the irregular slider 84, the limiting rod 892 will be forced to move up and down in the irregular groove 85, thereby allowing the second connecting rod 89 to drive one end of the first connecting rod 88 to swing up and down. The rotatable connection between connecting rod 2 89 and connecting rod 1 88 is close to the inner wall of the material distribution box 81. Therefore, when one end of connecting rod 2 89 moves up and down, the swing amplitude of the guide plate 87 can be increased through connecting rod 1 88.

[0031] In this embodiment, one end of the material distribution bar 86 is rotatably connected to one side of the connecting slider 83, and the material distribution bar 86 is slidably connected above the guide plate 87; Among them, the material distribution strip 86 is a soft rubber strip. The end of the material distribution strip 86 away from the connecting slider 83 is slidably connected to one end of the guide plate 87, so that when the guide plate 87 swings up and down, it can drive the material distribution strip 86 to swing synchronously; multiple material distribution strips 86 are distributed in a radiating pattern.

[0032] In this embodiment, a discharge box 15 is fixedly connected to the bottom of the support plate 14, a magnetic separation component 2 is installed on the inner side of the discharge box 15, a conveying component 3 is provided on one side of the discharge box 15, a crushing box side plate 12 and a crushing box side plate 13 are fixedly connected to each other, a hydraulic cylinder 61 is installed on the outer side of the crushing box side plate 13, and the output end of the hydraulic cylinder 61 is fixedly connected to the side plate 62. Among them, the magnetic separation component 2 is an existing magnetic separation conveying equipment, which can adsorb and separate magnetic materials in waste, while the conveying component 3 is used to convey the separated plastic to the next processing equipment, such as a spiral auger granulation equipment; the axial direction of the main crushing toothed disc 42 and the auxiliary crushing toothed disc 43 and the output direction of the magnetic separation component 2 are X-direction, and the sliding direction of the auxiliary slider 1 74, the auxiliary slider 2 75 and the sliding frame 82 is Y-direction.

[0033] The working principle of this invention is as follows: When it is necessary to recycle waste plastic shoe soles, the control equipment on the outside of the frame mechanism 1 can be used to operate the drive motor 41, hydraulic cylinder 61, magnetic separation component 2 and conveying component 3. The waste plastic shoe soles are then conveyed into the inside of the feeding hopper 11 through the external feeding conveyor belt. After passing through the internal parts of the guiding mechanism 5, crushing mechanism 4, auxiliary mechanism 7 and distributing mechanism 8 for crushing, the crushed material will reach the top of the magnetic separation component 2 for magnetic separation. The plastic fragments will be conveyed to the next processing stage through the conveying component 3. During the above process, when the waste plastic shoe soles fall into the inside of the feeding hopper 11, they will come into contact with the elastic combing strips 53 and 54, which will cause the shoe soles to bounce up, thus preventing the shoe soles from separating from each other. At the same time, since the combing strips 53 and 54 have a height difference, this difference causes the combing strips 53 and 54 to form multiple guide grooves, which allows the shoe soles to be perpendicular to the main crushing tooth disc 42 and the secondary crushing tooth disc 43 with the toe or heel of the shoe. In this way, the combing strips 53 and 54 can separate the shoe soles that are stuck together, and guide the posture of the shoe soles, thereby improving the "biting" efficiency of the crushing roller. After the drive motor 41 operates, the shaft in the middle of the main crushing disc 42 rotates via the belt. This, combined with the gear set on the other side of the main crushing disc 42, causes the auxiliary crushing disc 43 to rotate. The two rotating in opposite directions then crush the shoe sole. During this process, some material gets stuck in the gaps between the main crushing discs 42 and the auxiliary crushing discs 43. At this point, the operation of the hydraulic cylinder 61 causes the first side plate 62 to move downwards, and through the transmission slider 66, transmission gear 691, and linkage slider 67, the second side plate 63 moves upwards. This allows the second processing block 65 to lift the material remaining between the main crushing discs 42. The lifted material is then crushed again by the main crushing discs 42 and the auxiliary crushing discs 43. Once the first processing block 64 moves upwards, it further crushes the material. The material remaining between the multiple auxiliary crushing discs 43 is lifted up, thereby preventing some elastic material from getting stuck between the multiple main crushing discs 42 and the multiple auxiliary crushing discs 43. In addition, during the downward movement of processing block 1 64 and processing block 2 65, the material stuck between the multiple processing blocks 1 64 is carried away by the auxiliary crushing discs 43, and the material stuck between the multiple processing blocks 2 65 is carried away by the main crushing discs 42. Thus, during the alternating up and down reciprocating motion of processing blocks 1 64 and processing block 2 65, the material stuck between the multiple main crushing discs 42 and the multiple auxiliary crushing discs 43 can be processed, as well as the material stuck between themselves, thereby achieving the purpose of self-cleaning and preventing material from getting stuck between them. During the alternating up-and-down movement of the second side plate 63 and the first side plate 62, the upward movement of the first side plate 62 can cause the linkage gear 58 and the eccentric wheel 57 to rotate through the connecting rack 68 at its upper end, thereby causing the unit plate 52 to vibrate up and down. The upward movement of the second side plate 63 will cause the receiving plate 51 to vibrate up and down at a high frequency. Thus, during the alternating up-and-down movement of the first side plate 62 and the second side plate 63, the unit plate 52 and the receiving plate 51 will vibrate up and down alternately, thereby making the separation of materials by the first comb bar 53 and the second comb bar 54 more efficient. Furthermore, during the alternating up-and-down movement of processing block 1 64 and processing block 2 65, the downward movement of processing block 1 64 will push auxiliary slider 2 75 to move, and the downward movement of processing block 2 65 will cause auxiliary slider 1 74 to move. That is, auxiliary slider 1 74 and auxiliary slider 2 75 slide left and right synchronously. When auxiliary slider 2 75 moves, it pushes some of the stubborn waste material remaining between multiple secondary crushing toothed discs 43 to the periphery of the main crushing toothed disc 42. Through the convex teeth 78 above auxiliary slider 2 75 and the serrations on the periphery of the main crushing toothed disc 42, the material is crushed a second time. Similarly, the movement of auxiliary slider 1 74 will push the stubborn waste material between multiple main crushing toothed discs 42 to the periphery of the main crushing toothed disc 42 for further processing. This can further avoid material blockage and also perform secondary crushing to avoid material waste. During the synchronous left-right sliding of the auxiliary slider 74 and auxiliary slider 75, the sliding frame 82 can be driven to slide left-right within the distribution box 81, thereby enabling the scattering distribution strips 86 to dynamically disperse the material falling onto the guide plate 87. Simultaneously, during the left-right sliding of the sliding frame 82, the shaped slider 84 slides synchronously through the connecting slider 83, allowing the limiting rod 892 to reciprocate up-and-down within the wave-shaped shaped groove 85. This, in turn, causes the connecting rod 88 to reciprocate up-and-down through the connecting slider 891 and connecting rod 89. Consequently, the guide plate 87, along with the flexible connecting rod 89 attached above it, oscillates up-and-down, causing the crushed material to fall more evenly onto the magnetic separator 2. This makes the magnetic separator 2 more comprehensive during the magnetic separation process. Furthermore, since the connecting rod 89 is rotatably connected to the non-central part of the connecting rod 88, the oscillation amplitude of the guide plate 87 is amplified.
