Description

Technical Field

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

[0002] Once waste plastic packaging enters the environment, it is difficult to degrade, causing long-term and deep-seated ecological and environmental problems. Therefore, the recycling of waste plastic bottles is an important environmental protection action. In the process of recycling waste plastic bottles, it is necessary to use recycling equipment to process the waste plastic bottles into plastic fragments, and then the granulation equipment processes the plastic fragments into recycled plastic particles for reuse.

[0003] The patent with publication number CN115447023B discloses a waste plastic bottle recycling and processing equipment, including a processing box, a cutting and cleaning mechanism is arranged in the processing box, a drying barrel is connected below the processing box, and a drying mechanism is arranged in the drying barrel. The scheme transmits, cuts and cleans the waste plastic bottles in the cutting and cleaning mechanism. The cutting not only fragments the waste plastic bottles and reduces the subsequent storage space for plastics, but also discharges the air and liquid in the waste plastic bottles, avoiding the problem that the gas in the plastic bottles is difficult to discharge and causes inconvenience to the compression of the plastic bottles. Secondly, by cleaning the fragmented waste plastic bottles, the bacteria carried on the waste plastic bottles are removed.

[0004] In the above scheme, when the waste plastic bottles are cut, the label tape wrapped on the waste plastic bottles will also be cut, so that the plastic fragments produced by the cutting are mixed with label tape fragments. The label tape and the plastic bottle are made of different materials, which affects the purity and quality of the recycled plastic. In addition, the colored label tape may cause the recycled plastic to be dyed, limiting its application field. For this reason, the present invention provides a waste plastic recycling device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

A filter screen is arranged below the crushing roller, and the filter screen is fixedly installed in the main box body. A material storage box is placed on one side of the lower end of the main box body, and a label recycling machine is arranged at the upper end of the main box body. The label storage box is placed on the back of the main box body, the label recovery mechanism includes a conversion disk, the lower end surface of the conversion disk is in contact with the upper end surface of the main box body, four groups of mounting holes are arranged on the conversion disk at equal angles, a label suction mesh cover is fixedly installed in the mounting hole, the lower end surface of the label suction mesh cover is in contact with the upper end surface of the main box body, a support frame, the upper end of the conversion disk is rotatably connected to the support frame, the lower end of the conversion disk is rotatably connected to the main box body, a connecting pipe is fixedly installed on the support frame, one end of the connecting pipe is in contact with the upper end surface of the conversion disk, a docking hole and a blanking slot are arranged on the upper end of the main box body, the label storage box is located directly below the blanking slot, and a group of label suction mesh covers are directly opposite to the docking hole;

[0007] By driving the label-removing roller to rotate, the label tape on the plastic bottle is detached and fragmented, and then the fragmented label tape is recycled by the label recovery mechanism to avoid the fragmented label tape being mixed with the plastic blocks, thereby improving the purity and quality of the recycled plastic. Secondly, by driving the conversion disk to rotate, the label suction mesh cover is converted to ensure the label recovery mechanism's efficiency in recycling the label tape fragments in the main box.

[0008] Preferably, the label suction mesh cover comprises an upper cover, which is fixedly installed in the mounting hole, and two groups of arc-shaped mesh plates are symmetrically distributed below the upper cover, and a guide plate on the upper end of the arc-shaped mesh plates is fixedly connected, and a movable plate is arranged between the two groups of guide plates, and a movable plate fixedly connected to the pressure-bearing rod, and two groups of springs are symmetrically distributed on both sides of the movable plate, and a guide groove is arranged on the lower end surface of the upper cover, and the two groups of guide plates are slidably connected to the guide groove, and a slot is arranged on the upper end surface of the upper cover, and the movable plate is movably plugged into the slot, and an L-shaped rod is fixedly connected to the upper side of one end of the guide plate, and one end of the L-shaped rod extends into the movable plate, and a pin is arranged at one end of the L-shaped rod, and two groups of oblique sliding grooves are arranged on both sides of the movable plate, and the end of the pin is located in the oblique sliding groove, and an arc-shaped bar for supporting the pressure-bearing rod is arranged in the docking hole, and an inclined surface for pushing the pressure-bearing rod is arranged on one side of the blanking trough;

[0009] The impact generates vibration, which causes the smaller label tape fragments adsorbed on the curved mesh plate to be shaken off, ensuring that the label tape fragments in the label suction mesh cover completely fall into the label storage box.

[0010] Preferably, a shaking mechanism is also provided in the main box body, and the shaking mechanism includes a hinged rod, the hinged rod is hinged to the main box body, a flap fixedly connected to one end of the hinged rod, a fixed block is provided above the flap, a movable rod is provided above the other end of the hinged rod, the movable rod is movably plugged into the label removal barrel, the fixed block is fixedly installed in the main box body, a first rectangular groove is provided on the hinged rod, the lower end of the movable rod is located in the first rectangular groove, a second rectangular groove is provided at the upper end of the movable rod, and a convex shaft is provided at one end of the label removal roller, and the convex shaft is located in the second rectangular groove;

[0011] The plastic bottle is subjected to a secondary impact, and multiple impacts cause the label tape fragments attached to the plastic bottle to be shaken off, preventing the label tape fragments from being mixed into the plastic blocks, further improving the purity and quality of the recycled plastic.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. By driving the label-removing roller to rotate, the label tape on the plastic bottle is detached and fragmented, and then the fragmented label tape is recycled through the label recovery mechanism to avoid the fragmented label tape being mixed with the plastic block, thereby improving the purity and quality of the recycled plastic. Secondly, by driving the conversion disk to rotate, the label suction mesh cover is converted to ensure the label recovery mechanism's efficiency in recycling the label tape fragments in the main box.

[0014] 2. When the label suction mesh cover rotates toward the blanking chute, the pressure rod slides along the arc strip to the upper end surface of the main box until the label suction mesh cover moves above the blanking chute. At this time, the pressure rod loses the obstruction of the upper end surface of the main box, and under the action of the rebound force of the spring, the movable plate moves downward together with the pressure rod. At the same time, the ends of the two groups of pins slide along the corresponding oblique slide grooves respectively. Under the guidance of the oblique slide grooves, the two groups of pins drive the two groups of guide plates to move backwards along the guide grooves, and the two groups of guide plates drive the two groups of arc mesh plates to separate until the arc mesh plates hit the inner wall of the mounting hole. The impact generates vibration, which makes the smaller label tape fragments adsorbed on the arc mesh plates fall off, ensuring that the label tape fragments in the label suction mesh cover fall completely into the label storage box.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] Embodiment 1: Figures 1 to 3As shown, a waste plastic recycling device described in an embodiment of the present invention includes a main box body 1, a label stripping barrel 2 is fixedly connected to one side of the upper end of the main box body 1, a label stripping roller 3 is rotatably installed in the label stripping barrel 2, and a plurality of label stripping knives 31 for tearing off the note tape are installed on the outer ring of the label stripping roller 3, two groups of mutually meshing crushing rollers 4 are arranged in the main box body 1, gears 5 are installed at one end of the two groups of crushing rollers 4, and the two groups of gears 5 are meshed with each other, and a filter screen plate 6 is arranged below the crushing rollers 4, and the filter screen plate 6 is fixedly installed in the main box body 1, a material holding box 7 is placed on one side of the lower end of the main box body 1, a label recovery mechanism 8 is arranged on the upper end of the main box body 1, and a label storage box 9 is placed on the back side of the main box body 1, and the label recovery mechanism 8 includes a conversion Disk 801, the lower end surface of the conversion disk 801 fits in the upper end surface of the main box body 1, four groups of mounting holes 802 are opened at equal angles on the conversion disk 801, a label suction mesh cover 803 is fixedly installed in the mounting hole 802, the lower end surface of the label suction mesh cover 803 fits in the upper end surface of the main box body 1, a support frame 804, the upper end of the conversion disk 801 is rotatably connected to the support frame 804, the lower end of the conversion disk 801 is rotatably connected to the main box body 1, a connecting tube 805 is fixedly installed on the support frame 804, one end of the connecting tube 805 fits in the upper end surface of the conversion disk 801, a docking hole 101 and a blanking slot 102 are opened at the upper end of the main box body 1, the label storage box 9 is located directly below the blanking slot 102, and a group of label suction mesh covers 803 are directly opposite to the docking hole 101.

[0027] Specifically, the lower end surface of the label suction mesh cover 803 and the upper and lower end surfaces of the conversion disk 801 are all covered with a rubber layer. The inner diameter of the label suction mesh cover 803 is larger than the inner diameter of the docking hole 101. The other end of the connecting pipe 805 is connected to the vacuum pump. In the initial state, the lower end of a group of label suction mesh covers 803 is directly opposite to the docking hole 101, and the upper end of the mounting hole 802 corresponding to the group of label suction mesh covers 803 is directly opposite to one end of the connecting pipe 805. The label removal barrel 2 is located on one side of the main box body 1 in an inclined posture. When the discarded plastic bottles need to be recycled, the label removal barrel 2 is driven by a motor. The label roller 3 rotates, and then the discarded plastic bottles are thrown into the label stripping barrel 2. The rotating label stripping roller 3 stirs the plastic bottles through a plurality of groups of label stripping knives 31. At the same time, the plastic bottles slide along the inner cavity of the label stripping barrel 2 toward the inside of the main box 1. As the label stripping knife 31 stirs, the label stripping knife 31 collides with the label tape on the plastic bottle, so that the label tape on the plastic bottle is cut by the label stripping knife 31. After the label tape is cut by the label stripping knife 31 for many times, the label tape is not only separated from the plastic bottle, but also torn into pieces, thereby realizing the removal of the label tape of the plastic bottle. , the plastic bottles with the labels removed will slide into the material box 7 and fall onto the two groups of crushing rollers 4. The motor drives one group of crushing rollers 4 to rotate, and one group of crushing rollers 4 is driven by two groups of gears 5 to mesh and drive the other group of crushing rollers 4 to rotate synchronously. The two groups of crushing rollers 4 rotate to tear the plastic bottles into plastic blocks. The plastic blocks and the water in the plastic bottles will fall onto the filter screen 6. The water will pass through the filter screen 6 and fall to the bottom of the main box 1, and the plastic blocks will slide along the filter screen 6 into the material box 7. In this process, the vacuum pump is started and the docking hole 10 1 will generate suction force on the inside of the main box 1. Since the torn label tape is light, the suction force is smaller than the gravity of the plastic bottle, so that the torn label tape in the main box 1 moves toward the docking hole 101 along with the air, and the torn label tape will be sucked into a set of label suction net covers 803, and the air is sucked away by the connecting pipe 805 through the mesh holes on the label suction net covers 803, so that the torn label tape in the main box 1 is cleaned up. When the label tape fragments in the label suction net covers 803 are full, the conversion disk 801 is driven by the motor to rotate, and the rotation direction is the lower attachment Figure 1The middle arrow indicates the direction, and the label suction mesh cover 803 with the label tape fragments placed thereon will rotate together with the conversion disk 801, so that the upper end of the label suction mesh cover 803 is offset from one end of the connecting tube 805, until the label suction mesh cover 803 moves above the blanking trough 102, and the next group of label suction mesh covers 803 moves between the docking hole 101 and one end of the connecting tube 805, and continues to recycle the label tape fragments in the main box body 1. The label tape fragments that have lost their adsorption force in the label suction mesh cover 803 will fall into the label storage box 9, thereby realizing the recycling of the label tape. Compared with the prior art, by driving the label stripping roller 3 to rotate, the label tape on the plastic bottle is detached and fragmented, and then the fragmented label tape is recycled by the label recycling mechanism 8, so as to avoid the fragmented label tape being mixed with the plastic block, thereby improving the purity and quality of the recycled plastic. Secondly, by driving the conversion disk 801 to rotate, the conversion of the label suction mesh cover 803 is realized, so as to ensure the efficiency of the label recycling mechanism 8 in recycling the label tape fragments in the main box body 1.

[0028] like Figures 3 to 5 As shown, the label suction net cover 803 includes an upper cover 8031, which is fixedly installed in the installation hole 802, two groups of arc-shaped net plates 8032 are symmetrically distributed below the upper cover 8031, a guide plate 8033 fixedly connected to the upper end of the arc-shaped net plate 8032, a movable plate 8034 is arranged between the two groups of guide plates 8033, the movable plate 8034 is fixedly connected to the pressure-bearing rod 8035, two groups of springs 8036, and the two groups of springs 8036 are symmetrically distributed on both sides of the movable plate 8034, and a guide groove 311 is opened on the lower end surface of the upper cover 8031, and the two groups of guide plates 8033 are slidably connected to the guide groove 311 A slot 312 is provided on the upper end surface of the upper cover 8031, and the movable plate 8034 is movably plugged into the slot 312. An L-shaped rod 331 is fixedly connected to the upper side of one end of the guide plate 8033, and one end of the L-shaped rod 331 extends into the movable plate 8034, and a pin shaft 332 is provided at one end of the L-shaped rod 331. Two groups of oblique sliding grooves 341 are provided on both sides of the movable plate 8034, and the end of the pin shaft 332 is located in the oblique sliding groove 341. An arc strip 103 for supporting the pressure-bearing rod 8035 is provided in the docking hole 101, and an inclined surface 104 for pushing the pressure-bearing rod 8035 is provided on one side of the blanking trough 102.

[0029] Specifically, the above-mentioned label tape fragments will generate static electricity after multiple frictions. When the label tape fragments are collected in the label suction mesh cover 803, the label suction mesh cover 803 with static electricity will generate adsorption force on the inner wall of the label suction mesh cover 803. When the label suction mesh cover 803 moves to the top of the label storage box 9, some smaller label tape fragments cannot break free from the restraint brought by static electricity, and the smaller label tape fragments still remain in the label suction mesh cover 803. When the label suction mesh cover 803 is facing the docking hole 101, the lower end of the pressure rod 8035 is close to the arc strip 103, and the spring 8036 is in a compressed state. When the label suction mesh cover 803 rotates toward the blanking trough 102, the pressure rod 8035 slides along the arc strip 103 to the upper end surface of the main box body 1 until the label suction mesh cover 803 moves to the blanking trough 102. Above the material trough 102, the pressure-bearing rod 8035 loses the obstruction of the upper end surface of the main box body 1, and under the action of the rebound force of the spring 8036, the movable plate 8034 moves downward together with the pressure-bearing rod 8035, and at the same time, the ends of the two groups of pins 332 slide along the corresponding oblique slide grooves 341 respectively, and under the guidance of the oblique slide grooves 341, the two groups of pins 332 drive the two groups of guide plates 8033 to move backwards along the guide grooves 311, and the two groups of guide plates 8033 drive the two groups of arc-shaped mesh plates 8032 to separate until the arc-shaped mesh plates 8032 hit the inner wall of the mounting hole 802, and the impact generates vibration, so that the smaller label tape fragments adsorbed on the arc-shaped mesh plates 8032 are shaken off, ensuring that the label tape fragments in the label suction mesh cover 803 fall completely into the label storage box 9.

[0030] Embodiment 2: Figures 6 to 8 As shown, compared with Example 1, another embodiment of the present invention is: a shaking mechanism 10 is also arranged in the main box body 1, and the shaking mechanism 10 includes a hinged rod 111, the hinged rod 111 is hinged to the main box body 1, and a flap 112 is fixedly connected to one end of the hinged rod 111, and a fixed block 114 is arranged above the flap 112, and a movable rod 113 is arranged above the other end of the hinged rod 111, and the movable rod 113 is movably inserted into the label removal barrel 2, and the fixed block 114 is fixedly installed in the main box body 1, and a first rectangular groove 12 is opened on the hinged rod 111, and the lower end of the movable rod 113 is located in the first rectangular groove 12, and the upper end of the movable rod 113 is opened with a second rectangular groove 13, and a convex shaft 32 is arranged at one end of the label removal roller 3, and the convex shaft 32 is located in the second rectangular groove 13.

[0031] Specifically, during the collection process of plastic bottles, some of the plastic bottles will come into contact with water, resulting in the surface of some of the plastic bottles being wet. After the label tape is shredded, the smaller label tape fragments will adhere to the wet surface of the plastic bottle. After the plastic bottle is shredded by the crushing roller 4, the smaller label tape fragments will be mixed in the shredded plastic pieces. The plastic bottle with the label tape will slide into the main box 1, and the plastic bottle will first fall on the flap 112. At the same time, the rotating label-removing roller 3 drives the convex shaft 32 to rotate, and the convex shaft 32 drives the movable rod 113 to move upward. The movable rod 113 moving up and down drives the hinged rod 111 and the flap 112 to flip up and down. The flipping flap 112 flipping back and forth will hit the fallen plastic bottle, causing the plastic bottle to be hit. At the same time, the flap 112 throws the plastic bottle to the fixed block 114, and the plastic bottle hits the fixed block 114, causing the plastic bottle to be hit twice. Multiple impacts cause the fragments of the label attached to the plastic bottle to be shaken off, preventing the fragments of the label from being mixed into the plastic block, thereby further improving the purity and quality of the recycled plastic.

[0032] Working principle: the label stripping roller 3 is driven by a motor to rotate, and then the discarded plastic bottles are thrown into the label stripping barrel 2. The rotating label stripping roller 3 stirs the plastic bottles through several groups of label stripping knives 31. At the same time, the plastic bottles slide along the inner cavity of the label stripping barrel 2 toward the inside of the main box 1. As the label stripping knife 31 stirs, the label stripping knife 31 collides with the label tape on the plastic bottle, so that the label tape on the plastic bottle is cut by the label stripping knife 31. After the label tape is cut by the label stripping knife 31 for many times, the label tape is not only separated from the plastic bottle, but also torn into pieces, so that the label tape of the plastic bottle is removed. The plastic bottle with the label tape removed will slide into the material box 7 and fall onto two groups of crushing rollers 4. One group of crushing rollers 4 is driven by a motor to rotate, and one group of crushing rollers 4 is driven by two groups of gears 5 to mesh and transmit the other group of crushing rollers 4 to rotate synchronously. The two groups of crushing rollers 4 are The shredding roller 4 rotates to tear the plastic bottle into plastic blocks. The plastic blocks and the water in the plastic bottle will fall onto the filter screen plate 6. The water will fall to the bottom of the main box body 1 through the filter screen plate 6, and the plastic blocks will slide along the filter screen plate 6 into the material holding box 7. During this process, the vacuum pump is started, and the docking hole 101 will generate suction on the inside of the main box body 1. Since the torn label tape is lighter, the suction force is less than the gravity of the plastic bottle, so that the torn label tape in the main box body 1 moves toward the docking hole 101 with the air, and the torn label tape will be sucked into a group of label suction mesh covers 803, and the air is sucked away by the connecting pipe 805 through the mesh holes on the label suction mesh cover 803, so that the torn label tape in the main box body 1 is cleaned up. When the label tape fragments in the label suction mesh cover 803 are full, the conversion disk 801 is driven by the motor to rotate, and the rotation direction is attached below. Figure 1The middle arrow indicates the direction, and the label suction mesh cover 803 with the label tape fragments placed thereon will rotate together with the conversion disk 801, so that the upper end of the label suction mesh cover 803 is offset from one end of the connecting tube 805, until the label suction mesh cover 803 moves to above the blanking chute 102, and the next group of label suction mesh covers 803 moves to between the docking hole 101 and one end of the connecting tube 805, and continues to recycle the label tape fragments in the main box 1. The label tape fragments that have lost their adsorption force in the label suction mesh cover 803 will fall into the label storage box 9, thereby realizing the recycling of the label tape.
