Description

Technical Field

[0001] The present invention belongs to the technical field of waste recycling, and particularly relates to a waste recycling mechanism for plastic products and a recycling method thereof. Background Art

[0002] Plastic products are collectively referred to as daily and industrial supplies processed mainly with plastics, including products of all processes such as injection molding and thermoforming with plastics as raw materials. Plastics are a type of synthetic polymer material with plasticity, and together with synthetic rubber and synthetic fibers, they form the three indispensable synthetic materials in daily life. Specifically, plastics are materials mainly composed of natural or synthetic resins, added with various additives, which can be molded into a certain shape under certain conditions such as temperature and pressure and remain in the shape unchanged at normal temperature. During the production process of plastic products, a large amount of waste will be generated, and in order to save costs, it is usually necessary to use a recycling device to recycle the waste.

[0003] During the process of plastic waste recycling, in order to make the space occupied by the recycled waste smaller, first, the plastic waste is crushed, and then the crushed plastic waste is softened so that when it is finally compressed, the gap between the plastic wastes is smaller, thus reducing the problem that the recycled plastic waste occupies a large amount of space.

[0004] However, the following deficiencies exist in the above operation process:

[0005] 1. The pipeline at the connection between the crushing box and the heating box is affected by the heat transferred from the heating box, softening the plastic waste in the crushing box, which easily causes blockage of the pipeline at the connection between the crushing box and the heating box. Also, during the heating process of the crushed plastic waste by the heating box, the plastic waste close to the heating box is softened first, while the plastic waste in the middle of the heating box has a lower degree of softening, resulting in inconsistent softening degrees of the plastic waste in the heating box, thus affecting the subsequent compression effect.

[0006] 2. During the process of discharging the softened plastic waste after compression, it is necessary to unload the plastic waste compressed in the mold before loading the softened plastic waste from the heating box, resulting in a long unloading waiting time and thus reducing the working efficiency. Therefore, we provide a waste recycling mechanism for plastic products and a recycling method thereof to solve the above problems. Summary of the Invention

[0017] The present invention further includes a recycling method for a waste recycling mechanism of plastic products, which is characterized by including the following steps:

[0018] S01: First, put the plastic waste into the crushing box, and then start the crushing assembly to complete the crushing of the plastic waste.

[0019] S02: Then, the crushed plastic waste is discharged into the heating box to heat and soften the shredded waste. After softening, open the solenoid valve to discharge the softened plastic waste into the U-shaped frame of the receiving assembly.

[0020] S03: Then, start the hydraulic cylinder to drive the pressing plate to move into the U-shaped frame, thereby completing the compression of the plastic waste.

[0021] S04: Finally, control the U-shaped frame to move towards the material outlet direction, so that the compressed plastic waste is transferred to the lower part of the base, thereby completing the recycling of the plastic waste.

[0022] The present invention has the following beneficial effects: 1. By controlling the rotation of the two first rotating shafts, the first rotating shafts drive the crushing rollers to rotate, thereby completing the crushing of plastic waste. The crushed plastic waste enters the heating box, and the heating box heats the crushed plastic waste to soften it. The softened plastic waste enters one of the U-shaped frames in the receiving assembly through the discharge pipe. At this time, one U-shaped frame containing the softened plastic waste is facing the pressing plate, and the other U-shaped frame is exactly above the feeding port. Then, control the hydraulic cylinder to drive the pressing plate to move towards the U-shaped frame, so that the pressing plate squeezes the softened plastic waste, thereby completing the compression of the plastic waste. Finally, control the U-shaped frame to move towards the feeding port, so that the U-shaped frame drives the compressed plastic waste to move towards the feeding port, thereby completing the recycling of the compressed plastic waste. At the same time, the other empty U-shaped frame moves to just face the pressing plate. Through the synchronous movement of the two U-shaped frames, the recycling time of the compressed plastic waste is reduced, thereby effectively improving the recycling efficiency of plastic waste.

[0023] 2. By controlling the reciprocating up and down movement of the frustum-shaped block, when the frustum-shaped block moves upward, it is pressed by the plastic waste in the heating box, driving the turning plate to move away from the frustum-shaped block, so that the turning plate unfolds. As the frustum-shaped block continues to move upward, the turning plate turns the plastic waste in the heating box, making the plastic waste in the heating box heat more evenly, and then making the softening degree of the plastic waste remain close to the same. The plastic waste is compressed by the pressing plate, making the gap between the compressed plastic waste smaller, and then making the volume of the compressed plastic waste smaller. When the frustum-shaped block moves downward, under the elastic force of the torsion spring, it drives the turning plate to contract towards the frustum-shaped block, making the downward movement of the frustum-shaped block smoother. At the same time, through the reciprocating up and down movement of the frustum-shaped block, the push rod synchronously drives the cross bar to reciprocate up and down, preventing the heat in the heating box from being transferred upward to the crushing box, so that the plastic waste in the crushing box softens and becomes sticky, which makes it easy to stick together, resulting in the blockage of the feeding pipe. Through the reciprocating up and down movement of the cross bar, the plastic waste in the feeding pipe is dredged, thus ensuring the smoothness of the feeding pipe.

[0024] 3. By controlling the only motor power source to provide power for the operation of the crushing assembly, the turning and dredging assembly, and the receiving assembly, the full utilization of power is effectively improved, the use of multiple power sources is reduced, and thus the use cost is lowered.

[0025] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] A crushing component 2 is rotationally fitted inside the crushing box 103. The crushing component 2 includes a first rotating shaft 201 symmetrically penetrating and rotatably connected to an inner side surface of the crushing box 103, and a crushing roller 202 fixedly connected to a peripheral side surface of the first rotating shaft 201 and located inside the crushing box 103; A material turning and dredging component 3 is arranged inside the heating box 105. The material turning and dredging component 3 includes a frustum-shaped block 301 slidably arranged inside the heating box 105, an arc-shaped groove 302 is opened on a peripheral side surface of the frustum-shaped block 301, and a material turning plate 303 connected through a torsion spring is arranged inside the arc-shaped groove 302; A push-pull rod 304 extending into the feeding pipe 106 is fixedly connected to the top of the frustum-shaped block 301, and a cross rod 305 slidably fitted with the guiding groove 107 is fixedly connected to a peripheral side surface of the push-pull rod 304; A receiving component 4 is slidably fitted on the top of the base 101. The receiving component 4 includes two U-shaped frames 401 slidably arranged on the top of the base 101 (the heights of the pressing plate 110 and the U-shaped frames 401 both meet the usage requirements for compressing plastic waste, so that the plastic waste will not be extruded from the tops of the U-shaped frames 401 and the pressing plate 110 during the compression process), connecting columns 402 are symmetrically fixedly connected between the two U-shaped frames 401, an outer side surface of one of the U-shaped frames 401 is fixedly connected with an L-shaped plate 403 slidably connected to the base 101, the recycling component 1 further includes a first sliding groove 112 opened on the top of the base 101, the L-shaped plate 403 is slidably fitted with the first sliding groove 112, discharging openings 113 are symmetrically opened on the top of the base 101 and located outside the pressing plate 110, positioning plates 114 are symmetrically fixedly connected to the top of the base 101 and located outside the two discharging openings 113; A guiding hopper 115 located above the crushing component 2 is fixedly connected to the inside of the crushing box 103, and a plurality of support columns 116 are fixedly connected to the bottom of the base 101.

[0047] The operation process of this embodiment is as follows: First, put plastic waste into the crushing box 103. By controlling the rotation of the two first rotating shafts 201, the first rotating shafts 201 drive the crushing rollers 202 to rotate, thus completing the crushing of the plastic waste. The crushed plastic waste enters the interior of the heating box 105. The heating box 105 heats the crushed plastic waste to soften it. The softened plastic waste enters one of the U-shaped frames 401 in the receiving assembly 4 through the discharge pipe 108. At this time, one U-shaped frame 401 containing the softened plastic waste is facing the pressing plate 110, and the other U-shaped frame is exactly above the feeding port 113. Then, control the hydraulic cylinder 109 to drive the pressing plate 110 to move towards the U-shaped frame 401, so that the pressing plate 110 squeezes the softened plastic waste, thus completing the compression of the plastic waste. Finally, by controlling the U-shaped frame 401 to move towards the feeding port 113, the U-shaped frame 401 drives the compressed plastic waste to move towards the feeding port 113, thus completing the recycling of the compressed plastic waste. At the same time, the other empty U-shaped frame 401 moves to just face the pressing plate 110. Through the synchronous movement of the two U-shaped frames 401, the recycling time of the compressed plastic waste is reduced, thus effectively improving the recycling efficiency of the plastic waste;

[0048] During the process of the crushed plastic waste entering the heating box 105, synchronously control the reciprocating up and down movement of the frustum block 301. When the frustum block 301 moves upward, it is pressed by the plastic waste in the heating box 105, driving the turning plate 303 to move away from the frustum block 301, so that the turning plate 303 unfolds. As the frustum block 301 continues to move upward, the turning plate 303 completes the turning of the plastic waste in the heating box 105, making the plastic waste in the heating box 105 heat more evenly, and further making the softening degree of the plastic waste remain nearly the same. The plastic waste is compressed by the pressing plate 110, making the gap between the compressed plastic waste smaller, and further making the volume of the compressed plastic waste smaller. When the frustum block 301 moves downward, under the elastic force of the torsion spring, it drives the turning plate 303 to contract towards the frustum block 301, making the downward movement of the frustum block 301 smoother. At the same time, through the reciprocating up and down movement of the frustum block 301, synchronously drive the cross bar 305 to reciprocate up and down through the push rod 304, preventing the heat in the heating box 105 from being transferred upward to the crushing box 103, causing the plastic waste in the crushing box 103 to soften and become sticky, so that it is easy to stick together, resulting in the blockage of the feeding pipe 106. Through the reciprocating up and down movement of the cross bar 305, the plastic waste in the feeding pipe 106 is dredged, thus ensuring the smoothness of the feeding pipe 106.

[0049] Embodiment 2, please refer to Figures 1-15, in the second embodiment, the following improvements are made on the basis of the first embodiment. The crushing assembly 2 further includes an L-shaped rod 203 fixedly connected to an outer side surface of the crushing box 103. An end of the L-shaped rod 203 is fixedly connected with a motor 204. An output end of the motor 204 is fixedly connected to an end of one of the first rotating shafts 201. Meshing spur gears 205 are fixedly connected to the circumferential side surfaces of the two first rotating shafts 201. A worm 206 is fixedly connected to an end of the other first rotating shaft 201. The material turning and dredging assembly 3 further includes a first vertical plate 306 fixedly connected to the top of the base 101. A moving rod 307 extending into the heating box 105 is slidably connected through one side surface of the first vertical plate 306. A supporting rod 308 is spherical-jointed between the moving rod 307 and the frustum block 301. An end of the moving rod 307 away from the supporting rod 308 is fixedly connected with a pressing plate 309. A first spring 310 sleeved on the moving rod 307 is fixedly connected between the pressing plate 309 and the first vertical plate 306. The receiving assembly 4 further includes a first sliding rod 404 fixedly connected to an outer side surface of the other U-shaped frame 401. The first sliding rod 404 is slidably engaged with one of the positioning plates 114. An end of the first sliding rod 404 is fixedly connected with a baffle plate 405. A second spring 406 sleeved on the first sliding rod 404 is fixedly connected between the baffle plate 405 and one of the positioning plates 114. A first toothed plate 407 is fixedly connected to an outer side surface adjacent to one of the U-shaped frames 401. Cylindrical holes 408 are symmetrically formed in one side surface of the first toothed plate 407. Second sliding rods 409 are slidably connected to the inner circumferential surfaces of the cylindrical holes 408. A second toothed plate 410 is fixedly connected between the two second sliding rods 409. A return spring 411 sleeved on the second sliding rods 409 is fixedly connected between the inner bottom of the cylindrical hole 408 and the second toothed plate 410.

[0050] The operation process of this embodiment is as follows: By starting the motor 204, the motor 204 drives one of the first rotating shafts 201 to rotate, and then drives one of the spur gears 205 to rotate, thereby driving the other spur gear 205 meshing with it to rotate, so that the other spur gear 205 drives the other first rotating shaft 205 to rotate, thereby providing power for the rotation of the two first rotating shafts 205;

[0051] By pulling the pressing plate 309 to move away from the heating box 105, and then driving the frustum block 301 to move downward through the moving rod 307 and the supporting rod 308 (at this time, the first spring 310 is stretched), then making the pressing plate 309 not be stressed, and making the pressing plate 309 move in the direction of the heating box 105 under the elastic force of the first spring 310, thereby driving the frustum block 301 to move upward through the moving rod 307 and the supporting rod 308, providing power for the reciprocating up and down movement of the frustum block 301;

[0052] By controlling the first tooth plate 407 to move toward the L-shaped support plate 102, the U-shaped frame 401 close to the L-shaped support plate 102 moves to abut against the adjacent positioning plate 114 (the second spring 406 is compressed at this time). At this time, the U-shaped frame 401 close to the L-shaped support plate 102 is just facing the discharge port 113, and the other U-shaped frame 401 is facing the pressing plate 110, so that the U-shaped frame 401 facing the pressing plate 110 performs a compression operation on the plastic waste, so that the plastic waste compressed in the U-shaped frame 401 facing the discharge port 113 falls from the discharge port 113 and is then recovered;

[0053] After the first tooth plate 407 is free from stress, the elastic force of the second spring 406 drives the U-shaped frame 401 away from the L-shaped support plate 102 to move in the direction of the discharge port 113 away from the L-shaped support plate 102. Synchronously, the other U-shaped frame 401 moves to face the pressing plate 110. Through the reciprocating movement of the two U-shaped frames 401, one U-shaped frame 401 unloads the compressed plastic waste, and the other U-shaped frame 401 compresses the plastic waste, thereby improving the efficiency of plastic waste recycling.

[0055] The operation process of this embodiment is: the worm 206 is driven to rotate by one of the first rotating shafts 201, thereby driving the worm wheel 504 meshing with it to rotate, so that the worm wheel 504 drives the second rotating shaft 502 to rotate, and then drives the first bevel gear 503 and the first sprocket 505 to rotate, so that the first sprocket 505 drives the second sprocket 508 to rotate through the chain, thereby driving the third rotating shaft 503 to rotate, and the third rotating shaft 503 drives the cam 509 to rotate, so that the cam 509 contacts the resistance plate 309, and at the same time, with the cooperation of the first spring 310, the reciprocating movement of the resistance plate 309 is realized, providing power for the reciprocating movement of the resistance plate 309.

[0056] Example 4. Please refer to Figures 1-15 In this Example 4, on the basis of Example 1, the following improvements are made. A second driving assembly 6 is fixedly fitted to the top of the base 101. The second driving assembly 6 includes a second fixing plate 601 fixedly connected to the top of the base 101. One side surface of the second fixing plate 601 is fixedly connected with a mounting plate 602. The top of the mounting plate 602 is rotatably connected through a first transmission rod 603. The top end of the first transmission rod 603 is fixedly connected with a second bevel gear 604 meshing and cooperating with the first bevel gear 503. A sleeve 605 is slidably sleeved on the circumferential side surface of the first transmission rod 603 and is located below the mounting plate 602. Second sliding grooves 606 are symmetrically formed on the inner circumferential side surface of the sleeve 605. Clamping rods 607 slidably connected with the second sliding grooves 606 are symmetrically fixedly connected to the circumferential side surface of the first transmission rod 603. The bottom end of the sleeve 605 is fixedly connected with a third bevel gear 608. An annular groove 609 is formed on the outer circumferential side surface of the sleeve 605. A collar 610 is rotatably connected to the annular groove 609. A connecting plate 611 is fixedly connected to the outer circumferential side surface of the collar 610. A third sliding groove 612 is formed on one side surface of the second fixing plate 601. A slider 613 is slidably connected inside the third sliding groove 612. One side surface of the slider 613 is rotatably connected with a second transmission rod 614. A fourth bevel gear 615 meshing and cooperating with the third bevel gear 608 is fixedly connected to the circumferential side surface of the second transmission rod 614. A power gear 616 meshing and cooperating with the first toothed plate 407 and the second toothed plate 410 is fixedly connected to the end of the second transmission rod 614. An electric push rod 617 is fixedly connected to one side surface of the second fixing plate 601. The output end of the electric push rod 617 is fixedly connected with a connecting rod 618. The connecting rod 618 and the slider 613 are fixedly fitted. The connecting plate 611 is fixedly connected to the circumferential side surface of the connecting rod 618. A PLC controller is arranged inside the control box 111. The PLC controller is electrically connected to the heating box 105, the solenoid valve, the motor 204, and the electric push rod 617.

[0057] The operation process of this embodiment is as follows: Through the rotation of the first bevel gear 503, the second bevel gear 604 meshing with it is driven to rotate, so that the second bevel gear 604 drives the first transmission rod 603 to rotate. Through the clamping and cooperation of the clamping rod 607 on the first transmission rod 603 and the second sliding groove 606 on the sleeve 605, the sleeve 605 is further driven to rotate, and further drives the third bevel gear 608 to rotate, so that the third bevel gear 608 drives the fourth bevel gear 615 meshing with it to rotate, and the fourth bevel gear 615 drives the second transmission rod 614 to rotate, thereby driving the power gear 616 to rotate;

[0058] When controlling the U-shaped frame 401 to move towards the L-shaped support plate 102, the slider 613 is driven to move downward by controlling the electric push rod 617, so that the slider 613 drives the power gear 616 to move towards the first toothed plate 407 through the second transmission rod 614, making the power gear 616 engage with the first toothed plate 407. Then, the U-shaped frame 401 is driven to move towards the L-shaped support plate 102 through the first toothed plate 407, so that the U-shaped frame 401 close to the L-shaped support plate 102 abuts against the positioning plate 114 close to the L-shaped support plate 102. At this time, the power gear 616 just engages with the second toothed plate 410 (this process compresses the second spring 406). The power gear 616 continues to rotate, causing the power gear 616 to drive the second toothed plate 410 to move towards the first toothed plate 407, compressing the return spring 411 on the first toothed plate 407. During the process when the next tooth of the power gear 616 engages with the second toothed plate 410, under the elastic force of the return spring 411, the second toothed plate 410 is driven to reset, making the first toothed plate 407 continue to abut against the positioning plate 114, thus ensuring the normal rotation of the power gear 616 and not affecting the normal operation of other components;

[0059] When the U-shaped frame 401 far from the L-shaped support plate 102 moves towards the positioning plate 114 far from the L-shaped support plate 102, at this time, the slider 613 is driven to move upward by controlling the electric push rod 617, so that the slider 613 drives the power gear 616 to move away from the first toothed plate 407 through the second transmission rod 614, making the power gear 616 disengage from the second toothed plate 410. Under the elastic force of the second spring 406, the U-shaped frame 401 far from the L-shaped support plate 102 is driven to move towards the positioning plate 114 far from the L-shaped support plate 102, thus providing power for the first toothed plate 407 to drive the movement of the U-shaped frame 401.
