Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling, and in particular to a recycling device for waste plastics. Background Art

[0002] As the consumption of plastic products continues to increase, the amount of waste plastics is also increasing. The plastic production process consumes a lot of fossil energy, and these resources are limited. By recycling waste plastics, we can reduce our dependence on resources such as oil, which is of great significance to environmental protection, resource conservation and economic development.

[0003] At present, waste recyclers use large woven bags to hold the collected beverage bottles and then transport them to the recycling plant. In the recycling plant, the beverage bottles are sent to the plastic crusher for crushing and turning into small particles. These small particles are then processed by a series of cleaning, sorting, melting and other processing to remove impurities and improve their reuse value. The processed small particles can be turned into reusable materials for making new plastic products, such as plastic bottles and plastic bags. However, when loading some small plastic crushers, workers usually directly lift the woven bags to unload the materials, which is labor-intensive and inefficient; while large crushers need to use cranes to lift the woven bags, which increases the difficulty and complexity of operation. During the lifting process, accidents such as woven bag damage, plastic scattering or equipment jamming may occur. If the woven bags are not fully opened or handled improperly, they are easily involved in the crushing equipment and mixed with waste plastics, reducing the quality of recycled plastics, which not only affects the efficiency of waste recycling, but also may have a negative impact on the environment and the quality of recycled plastics.

DETAILED DESCRIPTION

[0035] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Embodiment 1: A waste plastic recycling device, such as Figure 1-Figure 4 As shown, it includes a crusher 1, a lower hopper 11 is fixedly connected to the top of the crusher 1, a rotating member 12 is rotatably connected to the upper rear of the lower hopper 11, a support rod 14 is fixedly connected to the left rear of the lower hopper 11, a servo motor 13 is installed on the support rod 14, the output shaft on the right side of the servo motor 13 is connected to the rotating member 12 through a coupling, the left and right parts of the rear side of the crusher 1 are fixedly connected to extrusion members 15, the rotating member 12 is slidably connected to sliding blocks 16 symmetrically distributed on the left and right, connecting springs 19 are connected between the two sliding blocks 16 and the rotating member 12, connecting pull ropes 17 are fixedly connected to the two sliding blocks 16, the movable ends of the two connecting pull ropes 17 are fixedly connected to clamps 18, and the extrusion member 15 and the adjacent sliding blocks 16 are extruded and matched.

[0037] like Figure 5-Figure 8 As shown, it also includes an ejection mechanism for pushing the woven bag upward from the bottom, the ejection mechanism is arranged on the rotating member 12, the ejection mechanism includes a fixed seat 2, two fixed seats 2 are fixedly connected to the left and right parts of the front side of the rotating member 12, a rotating wheel 24 is rotatably connected between the two fixed seats 2, a connecting frame 21 is fixedly connected to the right side of the rotating wheel 24, the connecting frame 21 and the fixed seat 2 on the right are also rotatably connected, a pulling torsion spring 211 is connected between the connecting frame 21 and the fixed seat 2 on the right, the pulling torsion spring 211 is wound on the connecting frame 21, an I-shaped slide groove is opened on the rotating member 12, and the top plate 23 slides in the I-shaped slide groove, a fixed pull rope 22 is fixedly connected to the lower rear side of the crusher 1, and the movable end of the fixed pull rope 22 is wound around the rotating wheel 24 and passes through the upper part of the rotating member 12 and is fixed to the top plate 23.

[0038] Initially, the sliding block 16 is pressed against the inclined surface of the extrusion member 15, so that the connecting spring 19 is in a deformed state. When it is necessary to feed the plastic crusher, the staff can move the woven bag containing the waste plastic to the rotating member 12, and the bottom of the woven bag will be pressed on the top plate 23. Then the woven bag is opened and the bag mouth is clamped with the clamps 18 on the left and right sides. Then the servo motor 13 is controlled to drive the rotating member 12 to flip upward 90°, thereby driving the sliding block 16, the fixed seat 2, the connecting frame 21, the top plate 23, the rotating wheel 24 and the woven bag to flip upward together. At this time, the bag mouth of the woven bag will face downward to the lower hopper 11, and the waste plastic in the woven bag will pour from the bag mouth into the lower hopper 11.

[0039] When the upward flipped sliding block 16 is separated from the extruding piece 15, under the elastic action of the connecting spring 19, the sliding block 16 will drive the connecting rope 17 and the clamp 18 to move toward the bottom of the bag, and the woven bag will be squeezed, so that the bag mouth of the woven bag will move toward the bottom of the bag all the time, thereby accelerating the dumping speed of the waste plastic. At the same time, as the fixed seat 2, the connecting frame 21, the top plate 23, and the rotating wheel 24 flip upward together, the fixed rope 22 is tightened, so that the connecting frame 21 and the rotating wheel 24 will rotate and reel in the fixed rope 22, and the pulling torsion spring 211 will be twisted, and the fixed rope 22 will drive the top plate 23 to move toward the direction close to the lower hopper 11, and the top plate 23 will push out the waste plastic inside from the bottom of the woven bag so that the waste plastic can be dumped out better.

[0040] As the waste plastic in the woven bag is dumped out, the woven bag will lose its support and become soft from a stiff state. At this time, the servo motor 13 can be controlled to drive the rotating member 12 to flip downward 90° and reset. According to the previous steps, the sliding block 16, the fixed seat 2, the connecting frame 21, the top plate 23, the rotating wheel 24 and the empty woven bag flip downward together. When the downward flipped sliding block 16 contacts the extrusion member 15, the inclined surface of the extrusion member 15 will squeeze the sliding block 16 so that it drives the clamp 18 to move toward the bag mouth through the connecting pull rope 17. The woven bag will return to its normal height, and the connecting spring 19 will return to the deformed state. At the same time, under the action of pulling the torsion spring 211, the connecting frame 21 and the rotating wheel 24 rotate to release the fixed pull rope 22. At the same time, under the action of its own gravity, the top plate 23 also moves away from the lower hopper 11 and resets.

[0041] At this time, the staff can make the clamp 18 loosen the empty woven bag and take it away from the rotating part 12, and finally control the plastic crusher to crush the waste plastic. In summary, the rotating part 12, the extruding part 15, the sliding block 16, the connecting rope 17, the clamp 18 and the like cooperate with each other to achieve a firm clamping and precise positioning of the woven bag. When the woven bag is placed in the designated position, these components work together to ensure that the woven bag will not slip or shift during the flipping and dumping process, and then the waste plastic inside is pushed out from the bottom of the bag through the top plate 23, effectively pushing the waste plastic in the bag to the bag mouth, thereby speeding up the discharge speed, which not only improves work efficiency, but also ensures that the waste plastic can be completely and quickly dumped out of the woven bag, prepares for subsequent crushing processing, and improves the performance of the waste plastic recycling equipment.

[0042] Embodiment 2: Based on embodiment 1, Figure 9-11As shown, it also includes a limiting mechanism for clamping the middle part of the woven bag, the limiting mechanism is arranged on the rotating member 12, and the limiting mechanism includes a connecting seat 3, the connecting seat 3 is fixedly connected to the left side of the rotating member 12, and a limiting frame 33 is rotatably connected in the connecting seat 3, the rotating frame 31 is fixedly connected to the bottom of the limiting frame 33, the rotating frame 31 and the rotating member 12 are also rotatably connected, a reset torsion spring 32 is connected between the rotating frame 31 and the rotating member 12, the reset torsion spring 32 is wound around the rotating frame 31, and a connecting block 34 is fixedly connected to the lower side of the rotating frame 31, a latch assembly is provided on the left side of the bottom of the rotating member 12, and a fixing rod 35 is fixedly connected to the lower left part of the rear side of the crusher 1.

[0043] like Fig.10 As shown, the latch assembly includes a support block 37, which is fixed to the bottom left side of the rotating member 12. A limit member 36 is slidably connected to the support block 37, and a linear spring 38 is connected between the limit member 36 and the support block 37. A socket is opened on the lower side of the rotating frame 31, and the limit member 36 slides in the socket, and the fixing rod 35 is squeezed and fitted with the limit member 36.

[0044] Initially, the fixing rod 35 will press the connecting block 34 and the limiting member 36 against the reset torsion spring 32, so that the linear spring 38 is in a twisted state. When the servo motor 13 drives the rotating member 12 to flip upward 90°, the rotating member 12 will also drive the connecting seat 3, the limiting frame 33, the rotating frame 31, the connecting block 34, the limiting member 36, etc. to flip upward together. When the upwardly flipped connecting block 34 and the limiting member 36 are separated from the fixing rod 35, under the action of the reset torsion spring 32 and the elastic action of the limiting member 36, the rotating frame 31 will drive the limiting frame 33 and the connecting block 34 to rotate right, and the limiting member 36 will move forward to be inserted into the plug hole of the rotating frame 31, and the limiting frame 33 rotating right will clamp the middle part of the woven bag to prevent the bag body from turning from the outside to the inside when pouring, thereby avoiding the risk of the woven bag being accidentally involved in the crushing mechanism.

[0045] When the rotating member 12 flips downward 90° to reset, it drives the rotating frame 31, the connecting block 34, the limit member 36, etc. to flip downward together. When the downward-turned limit member 36 contacts the fixed rod 35, the fixed rod 35 will resist the limit member 36, causing the limit member 36 to move backward to withdraw from the insertion hole of the rotating frame 31, and the fixed rod 35 will also resist the connecting block 34 to drive the rotating frame 31 and the limit frame 33 to flip left and reset. In summary, through the cooperation of the connecting block 34 and the fixed rod 35, as well as the elastic action of the reset torsion spring 32 and the limit member 36, the equipment successfully realizes the stable tightening and anti-flipping function of the middle part of the woven bag, which not only improves the stability and safety of the waste plastic recycling equipment, but also ensures that the woven bag can be emptied smoothly and safely.

[0046] like Figure 12-14As shown, it also includes a pushing mechanism for shaking the woven bag, the pushing mechanism is arranged on the rotating member 12, the pushing mechanism includes a pushing frame 42, the pushing frame 42 is slidably connected to the rotating member 12, a connecting rod 41 is fixedly connected to the right side of the connecting frame 21, a transmission frame 4 is fixedly connected to the lower right side of the pushing frame 42, the connecting rod 41 passes through the transmission frame 4, a clamping assembly is provided on the upper side of the rotating member 12, six evenly distributed grooves are opened on the rotating member 12, and the pushing frame 42 slides in the six grooves.

[0047] like Fig.14 and Fig.15 As shown, the clamping assembly includes a fixed block 44, and the two fixed blocks 44 are respectively fixed to the left and right parts of the upper side of the rotating member 12, and a limit frame 43 is rotatably connected between the two fixed blocks 44. A connecting torsion spring 45 is connected between the limit frame 43 and the two fixed blocks 44, and the two connecting torsion springs 45 are both wound around the adjacent limit frames 43, and the limit frame 43 is provided with four evenly distributed toothed blocks.

[0048] When the clamp 18 clamps the bag opening of the woven bag from the left and right sides, the limiting frame 43 is rotated upward, and the toothed block on the limiting frame 43 will stay above the bag opening, the connecting torsion spring 45 will be twisted, and the limiting frame 43 will be loosened. Under the action of the connecting torsion spring 45, the limiting frame 43 will flip downward to press the toothed block on the bag opening, so that the left and right front three sides of the woven bag are clamped and fixed, so that the bag opening is opened large enough to facilitate the dumping of waste plastics. When the connecting frame 21 and the rotating wheel 24 rotate, the connecting frame 21 will drive the connecting rod 41 to rotate together, thereby driving the transmission frame 4 and the pushing frame 42 to move forward and backward. The reciprocating movement of the pushing frame 42 back and forth will cause the woven bag to shake, which helps to break the adhesion and accumulation of waste plastics, making it easier for them to slide out of the bag mouth, thereby speeding up the discharge speed of the woven bag. In summary, the front side of the bag mouth is first clamped by the limiting frame 43, so that the area of ​​the bag mouth is increased, providing sufficient space for the dumping of waste plastics, and then through the cooperation of the connecting rod 41, the transmission frame 4, and the pushing frame 42, the woven bag is shaken, which further speeds up the discharge speed of the waste plastics, not only improving the efficiency of waste plastic recycling, but also ensuring the stability and safety of the operation process.
