Description

Technical Field

[0001] The present invention relates to the technical field of plastic recycling, and particularly relates to a rolling and crushing treatment device for recycling waste plastics. Background Art

[0002] In the process of recycling waste plastics, a rolling and crushing treatment device is used to apply mechanical forces of extrusion and shear forces to plastic materials, so as to crush the plastics into smaller fragments for subsequent cleaning and granulation processes.

[0003] When crushing the insulation of waste electric wires, there are many problems: (1) It is necessary to first use a separation device to separate the insulation from the wire, and then transfer the insulation to the crushing roller of the rolling and crushing treatment device for crushing. The separation and treatment of the insulation are difficult to be carried out continuously, affecting the overall recycling efficiency; (2) After the insulation is cut by mechanical force, the untreated insulation is likely to break away from the crushing roller, and the insulation needs to be fed in again, resulting in the interruption of the treatment process, increasing the number of manual interventions, and affecting the overall crushing efficiency. Summary of the Invention

[0004] In view of this, the present invention provides a rolling and crushing treatment device for recycling waste plastics.

[0005] Technical Solution: A rolling and crushing treatment device for recycling waste plastics includes a crushing frame, on which a pair of crushing rollers are installed. A fixed frame is connected to the crushing frame, and a sliding lifting frame is provided on the fixed frame. A feeding roller with spikes on its surface is rotatably connected to the lifting frame. A placing frame is connected to the fixed frame. Two groups of guide wheels are rotatably connected to the upper part of the placing frame. Two fixing blocks are connected to the upper part of the placing frame, and cutting mechanisms are installed on the fixing blocks. A pair of guide blocks are slidably connected to the side surfaces of the fixing blocks, and each pair of guide blocks has an inclined guide surface on the side away from each other; after the cutting mechanism cuts the insulation, under the guidance of the guide wheels, the wire passes through a pair of guide blocks, and the insulation is separated from the wire along the guide surface.

[0006] In addition, particularly preferably, the cutting mechanism includes a lower cutting knife, a rotating block, a mounting block, a bolt, an upper cutting knife, and a limiting component. Grooves are opened at the tops of the fixing blocks, and lower cutting knives are installed at the grooves of the fixing blocks. Rotating blocks are rotatably connected to the fixing blocks, sliding mounting blocks are provided in the middle of the rotating blocks, bolts in threaded connection with the mounting blocks and in close contact with the mounting blocks are provided on the rotating blocks, upper cutting knives are installed on the mounting blocks, and limiting components are provided on the rotating blocks.

[0007] In addition, particularly preferably, the distance between the upper cutting knife and the lower cutting knife gradually decreases.

[0008] In addition, it is particularly preferred that the limiting component includes a limiting block and a triangular block. Limiting blocks are slidably connected to the rotating blocks. A return spring is connected between the limiting block and the rotating block. The lower part of each limiting block has a triangular portion. Triangular blocks that cooperate with the triangular portions are connected to one side of the fixed block close to the triangular portion. Both the top of the triangular block and the bottom of the triangular portion have inclined surfaces.

[0009] In addition, it is particularly preferred that the rolling and crushing processing device further includes a bidirectional screw. Bidirectional screws are rotatably connected to the sides of the fixed blocks. The guiding blocks are threadedly connected to the bidirectional screws.

[0010] In addition, it is particularly preferred that the rolling and crushing processing device further includes a winding mechanism. The winding mechanism includes a fixing plate. A pair of fixing plates are connected to the side of the placing frame. Rotating discs are rotatably connected to the tops of the fixing plates. Winding cylinders for winding wires are connected to one side of the two rotating discs close to each other. Square grooves are provided on the winding cylinders. Sliders that slide axially along the winding cylinders are provided in the square grooves of the winding cylinders. Protrusions that slide radially along the winding cylinders are provided on the sliders. One end of the protrusion extends out of the square groove to the outside of the winding cylinder. A guide rod is provided at the other end of the protrusion. Guide grooves are provided inside the winding cylinders. In the axial direction of the winding cylinder, the guide grooves are divided into an inclined section and a straight section. The end of the guide rod is located in the guide groove.

[0011] In addition, it is particularly preferred that the winding mechanism further includes a connecting plate. A sliding connecting plate is provided on the fixing plate. Guide discs are connected to the tops of the connecting plates. Connecting blocks are connected to the sliders. Rollers located outside the winding cylinder are rotatably connected to the connecting blocks. A chute for the roller to be embedded is provided at the edge of the guide disc.

[0012] In addition, it is particularly preferred that the rolling and crushing processing device further includes a material guiding plate. The material guiding plate is connected to the inner bottom of the placing frame.

[0013] The beneficial effects of the present invention are as follows: 1. The waste wire passes through the groove, and the upper cutter and the lower cutter cut open the insulating skin. The cut insulating skin is separated from the wire along the guiding surface. The rotating feeding roller feeds the insulating skin to the rotating crushing roller for crushing treatment. The insulating skin is subjected to the pulling force of the feeding roller, so that the waste wire continues to be conveyed along the guiding wheel, thereby automatically separating the insulating skin and the wire without repeated feeding, with strong continuity and effectively improving the overall crushing efficiency.

[0014] 2. By rotating the bolt, the mounting block and the upper cutter move up and down, and the distance between the upper cutter and the lower cutter is adjusted according to the thickness of the waste wire. By rotating the bidirectional screw, the distance between a pair of guiding blocks is adjusted, with flexible adjustment and high adaptability.

[0015] 3. After the wire is separated from the insulating skin, under the action of the guide wheel, the end of the wire is wound around the convex block. While the feeding roller conveys the insulating skin, control the second reduction motor to rotate the turntable, winding cylinder, slider, guide rod, convex block, connecting block and roller as a whole. The rotating convex block drives the wire to be wound around the winding cylinder, improving the overall recycling efficiency.

[0016] 4. Control the second electric push rod to move the connecting plate, guide disk, roller, connecting block, convex block, slider and guide rod as a whole. The guide rod enters the straight section along the inclined section of the guide groove, making the convex block move inside the winding cylinder. The convex block is separated from the end of the wire, and the continuously moving connecting block automatically pushes out the wire wound around the winding cylinder, so as to quickly and centrally recycle the wire.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Embodiment 1: A rolling and crushing treatment device for waste plastic recycling, refer to Figures 1-8 , including a crushing frame 1, a crushing roller 2, a fixed frame 3, a lifting frame 4, a first electric push rod 41, a feeding roller 5, a placing frame 6, a guide wheel 7, a fixed block 8, a cutting mechanism and a guide block 9. A pair of crushing rollers 2 driven by a servo motor are installed on the crushing frame 1. The structure and crushing principle of the crushing roller 2 are prior art. The front side of the top of the crushing frame 1 has a feeding port. A fixed frame 3 is fixedly connected to the crushing frame 1 at the feeding port. A lifting frame 4 that slides up and down is provided on the fixed frame 3. The first electric push rods 41 are bolted to the upper parts of the left and right sides of the crushing frame 1. The telescopic rods of the first electric push rods 41 are connected to the lifting frame 4. A feeding roller 5 driven by a first reduction motor is rotatably connected to the lifting frame 4. The surface of the feeding roller 5 has spikes for piercing the insulating skin 21. A placing frame 6 is welded to the front side of the fixed frame 3. Two groups of guide wheels 7 are rotatably connected to the upper part of the placing frame 6. Each group of guide wheels 7 has three. The positions of each group of guide wheels 7 are as Figure 5 shown. Two fixed blocks 8 are fixedly connected to the upper part of the placing frame 6. Cutting mechanisms are installed on the fixed blocks 8. A pair of guide blocks 9 are slidably connected to the rear sides of the fixed blocks 8. The mutually remote sides of each pair of guide blocks 9 have inclined guiding surfaces 90; when the insulating skin 21 is cut by the cutting mechanism, under the guiding action of the guide wheels 7, the conducting wire 22 passes through between a pair of guide blocks 9, and the insulating skin 21 is separated from the conducting wire 22 along the guiding surface 90.

[0030] Refer to Figures 4-7, the cutting mechanism includes a lower cutter 81, a rotating block 82, a mounting block 84, a bolt 85, an upper cutter 86 and a limiting component. Grooves 80 are formed in the middle of the top of the fixed block 8. Lower cutters 81 are installed at the grooves 80 of the fixed block 8. Rotating blocks 82 with rotating shaft parts 83 are rotatably connected to the fixed block 8. The rotating block 82 rotates around the rotating shaft part 83. Sliding mounting blocks 84 are provided in the middle of the rotating block 82. Bolts 85 are threadedly connected to the front sides of the rotating block 82. The ends of the bolts 85 are in close contact with the mounting block 84 to limit the position of the mounting block 84. Upper cutters 86 are installed on the lower sides of the mounting blocks 84. The distance between the upper cutter 86 and the lower cutter 81 gradually decreases from front to back. A limiting component is provided on the rotating block 82; the limiting component includes a limiting block 87 and a triangular block 89. Limiting blocks 87 are slidably connected to one ends of the rotating block 82 far from the rotating shaft part 83. A return spring is fixedly connected between the limiting block 87 and the rotating block 82. Triangular parts 88 are provided at the lower parts of the limiting blocks 87. Triangular blocks 89 matched with the triangular parts 88 are connected to one sides of the fixed block 8 close to the triangular parts 88. Bevels are provided at the tops of the triangular blocks 89 and the bottoms of the triangular parts 88.

[0031] Reference Figure 8 , the rolling and crushing processing equipment further includes a bidirectional screw 91. Bidirectional screws 91 are rotatably connected to the rear sides of the fixed block 8. The guide block 9 is threadedly connected to the bidirectional screw 91.

[0032] Reference Figure 4 , the rolling and crushing processing equipment further includes a guide plate 61. The guide plate 61 is fixedly connected to the inner bottom of the placing frame 6.

[0033] First step, manually pull the limiting block 87 to make the triangular part 88 of the limiting block 87 disengage from the triangular block 89. The return spring deforms and pushes the limiting block 87 to drive the rotating block 82 to rotate upward around the rotating shaft part 83. The rotating block 82 drives the mounting block 84 and the upper cutter 86 to move synchronously. Release the limiting block 87, and the limiting block 87 is reset relative to the rotating block 82 under the action of the return spring.

[0034] Second step, place the waste wire in the placing frame 6, and pass the end of the waste wire through the groove 80. Then push the rotating block 82 to rotate downward and reset, driving the mounting block 84, the upper cutter 86 and the limiting block 87 to move synchronously. When the bevel of the triangular part 88 of the limiting block 87 contacts the bevel of the triangular block 89, the limiting block 87 is squeezed by the triangular block 89 to make the limiting block 87 slide, and the return spring deforms. When the triangular part 88 passes over the triangular block 89, the return spring restores and drives the limiting block 87 to reset. The top of the triangular part 88 contacts the bottom of the triangular block 89, and the triangular block 89 limits the limiting block 87, thereby limiting the rotating block 82.

[0035] In the third step, the rear ends of the upper cutting knife 86 and the lower cutting knife 81 respectively cut into the insulating skin 21 from above and below. An operator pulls the waste wire backward for a certain distance. When the waste wire passes through the upper cutting knife 86 and the lower cutting knife 81, the upper cutting knife 86 and the lower cutting knife 81 cut the insulating skin 21 into two sections, left and right. The cut insulating skin 21 separates from the wire 22 along the guiding surface 90, and the wire 22 passes through between a pair of guiding blocks 9.

[0036] In the fourth step, control the electric push rod 1 to drive the lifting frame 4 to rise, driving the feeding roller 5 to rise. Place the insulating skin 21 separated from the wire 22 above the feeding roller 5. Control the electric push rod 1 to lower the lifting frame 4 and the feeding roller 5 until the spikes of the feeding roller 5 pierce into the insulating skin 21.

[0037] In the fifth step, control the reduction motor 1 to drive the feeding roller 5 to rotate counterclockwise. At the same time, control the servo motor to drive the crushing roller 2 to rotate. The feeding roller 5 feeds the insulating skin 21 to the crushing roller 2 for crushing treatment. The insulating skin 21 is subjected to the pulling force of the feeding roller 5, causing the waste wire to continue to be conveyed backward along the guiding wheel 7. The guiding wheel 7 plays a guiding role. The upper cutting knife 86 and the lower cutting knife 81 continue to cut the insulating skin 21 of the waste wire 22. With the cooperation of the guiding surface 90, the insulating skin 21 and the wire 22 are automatically separated. The separated insulating skin 21 is automatically sent by the feeding roller 5 to the crushing roller 2 for crushing treatment, without repeated feeding, with strong continuity, effectively improving the overall crushing efficiency.

[0038] When it is necessary to recycle waste wires of different thicknesses, an operator rotates the bolt 85 manually to loosen the mounting block 84, and then can push the mounting block 84 to slide up and down, driving the upper cutting knife 86 to move up and down. Then tighten the bolt 85 to fix the position of the mounting block 84, so as to be able to adjust the distance between the upper cutting knife 86 and the lower cutting knife 81 according to the thickness of the waste wire. An operator rotates the bidirectional screw 91 manually, and under the action of screw connection, the guiding block 9 slides in the left-right direction to adjust the distance between a pair of guiding blocks 9 according to the thickness of the waste wire. The adjustment is flexible and has high adaptability.

[0039] Embodiment 2: On the basis of Embodiment 1, refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 9 and Figure 10, the crushing and rolling equipment further includes a winding mechanism. The winding mechanism includes a fixing plate 101, a turntable 102, a winding cylinder 103, a slider 105, a convex block 106 and a guide rod 107. A pair of fixing plates 101 are bolted to the front side of the placing frame 6. The tops of the fixing plates 101 are rotatably connected to turntables 102 respectively. A second reduction motor for driving the turntables 102 to rotate is installed on the fixing plates 101. Winding cylinders 103 for winding the conducting wires 22 are connected to the sides of the two turntables 102 close to each other. Square grooves 104 are formed in the winding cylinders 103. Sliders 105 that slide axially along the winding cylinders 103 are arranged in the square grooves 104 of the winding cylinders 103. Convex blocks 106 that slide radially along the winding cylinders 103 are arranged on the sliders 105. One end of each convex block 106 extends out of the winding cylinder 103 from the square groove 104, and a guide rod 107 is arranged at the other end of the convex block 106. Guide grooves 108 are formed inside the winding cylinders 103. In the axial direction of the winding cylinders 103, the guide grooves 108 are divided into an inclined section and a straight section, and the ends of the guide rods 107 are located in the guide grooves 108.

[0040] Reference Figure 4 , Figure 5 , Figure 9 and Figure 10 , the winding mechanism further includes a connecting plate 111, a second electric push rod 112, a guiding disc 113, a connecting block 114 and a roller 115. The fixing plates 101 are provided with connecting plates 111 that slide left and right. Second electric push rods 112 are bolted to the lower parts of the fixing plates 101 respectively. The telescopic rods of the second electric push rods 112 are connected to the connecting plates 111. Guiding discs 113 are fixedly connected to the tops of the connecting plates 111 respectively. Connecting blocks 114 are fixedly connected to the sliders 105. Rollers 115 located outside the winding cylinders 103 are rotatably connected to the connecting blocks 114. The edges of the guiding discs 113 have chutes for the rollers 115 to be embedded in.

[0041] After the wire 22 is separated from the insulation 21, the wire 22 is wound around the uppermost guide wheel 7, and the end of the wire 22 is wound around the bump 106. While the feeding roller 5 conveys the insulation 21, the control deceleration motor two drives the turntable 102 to rotate, driving the winding cylinder 103, the slider 105, the guide rod 107, the bump 106, the connecting block 114 and the roller 115 to rotate as a whole. The roller 115 rolls along the chute, and the rotating bump 106 drives the wire 22 to be automatically wound around the winding cylinder 103, improving the overall recycling efficiency. When the waste wire treatment is completed, the control push rod two 112 drives the connecting plate 111 to slide, driving the two guide disks 113 to move towards each other. Since the roller 115 is embedded in the chute, the roller 115, the connecting block 114, the bump 106, the slider 105 and the guide rod 107 move together with the guide disk 113. When the guide rod 107 enters the straight section along the inclined section of the guide groove 108, the guide rod 107 drives the bump 106 to move into the interior of the winding cylinder 103. Since the wire 22 is wound around the winding cylinder 103, the moving bump 106 will be separated from the end of the wire 22. The control push rod two 112 makes the connecting plate 111, the guide disk 113, the roller 115, the connecting block 114, the bump 106, the slider 105 and the guide rod 107 continue to move, and the connecting block 114 automatically pushes out the wire 22 wound around the winding cylinder 103 for quick centralized recycling of the wire 22. Subsequently, the control push rod two 112 makes the connecting plate 111, the guide disk 113, the roller 115, the connecting block 114, the bump 106, the slider 105 and the guide rod 107 move back to their original positions. The guide rod 107 enters the inclined section along the straight section of the guide groove 108, causing the bump 106 to extend out of the winding cylinder 103 again, and then the winding of the wire 22 can continue.

[0042] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
