The first electric push rod is connected to the inner wall of the cleaning frame. A translation cylinder sleeved on the rotating rod is connected to the telescopic rod of the first electric push rod. A straight groove for the convex strip portion to extend into is formed on the translation cylinder.

[0011] As a preferred technical solution of the present invention, one end of the translation cylinder close to the convex strip portion has an inclined surface. When the translation cylinder moves, the convex strip portion is squeezed through the inclined surface so that the convex strip portion extends into the straight groove.

[0012] As a preferred technical solution of the present invention, the friction cleaning machine for plastic recycling further includes a feeding frame. The feeding frame is connected to the cleaning frame. A first vertical plate and a second vertical plate are connected to the feeding frame.

A second return spring is connected between the outer cylinder and the lifting block. A plug is connected to the eccentric position at the rear end of the outer cylinder. A jack for the plug to insert into is formed on the upper part of the first vertical plate.

[0013] Beneficial effects: 1. The clamping member clamps the end of the waste wire. The moving translation block and the traction rod sequentially pass through each arc-shaped opening and the opening of the arc-shaped rack to traction the waste wire. The conveying wheel conveys the waste wire. The spray head on the cleaning frame sprays water. The waterproof motor is controlled to make the gear rotate, driving the arc-shaped rack and the scrubbing plate to rotate continuously. The scrubbing plate brushes the surface of the waste wire through the friction of the bristles, so as to recycle the waste wire, reduce manual intervention and improve the recycling efficiency.

[0014] 2. After the waste wire is cleaned, the rotating rod, gear, arc rack and brushing plate stop rotating. Control the first electric push rod to move the translation cylinder to the left. The translation cylinder rotates by squeezing the convex strip part through the inclined plane, and the convex strip part aligns with the straight groove, driving the rotating rod, gear, arc rack and brushing plate to rotate together. The opening of the arc rack faces upward, so as to automatically position the arc rack.

[0015] 3. The traction rod drives the first fixing block and the sliding cylinder to move to the left. The first fixing block pushes the sliding rod. Under the action of the hinge rod, the two vertical rods approach each other. The sliding column slides on the second fixing block, and the pressing wheel contacts the surface of the waste wire to limit the waste wire.

[0016] 4. The leftward moving sliding cylinder contacts the contact plate. The translation block, traction rod and first fixing block continue to move to the left. The rotating shaft part and the convex block move relatively. Since the convex block is located in the thread groove, the traction rod and the clamping part rotate upward with the rotating shaft part as the axis to avoid blocking the subsequent waste wire and improve the operation convenience.

[0017] 5. Pull the outer cylinder, the plug leaves the jack, push the outer cylinder upward, the lifting block and the upper limit wheel move upward. Place the end of the waste wire on the lower limit wheel. The outer cylinder, lifting block and upper limit wheel move downward, and the plug is inserted back into the jack. Pull the waste wire to remind people to process the knotted part of the waste wire. BRIEF DESCRIPTION OF THE DRAWINGS

Specific Embodiment

[0030] Embodiment 1: A friction cleaning machine for plastic recycling, refer to Figures 1-6, including a cleaning frame 1, a mounting plate 2, a scrubbing plate 3, a guide rail 4, a translation block 5, a traction rod 6 and a conveying wheel 7. Inside the cleaning frame 1, multiple rows of nozzles are installed. The nozzles are of the prior art and not shown in the figure. Two mounting plates 2 are welded to the right side inside the cleaning frame 1. Between the two mounting plates 2, two rotatable scrubbing plates 3 are arranged. On the side where the two scrubbing plates 3 face each other, bristles are provided. Above the cleaning frame 1, a guide rail 4 is fixedly connected. On the guide rail 4, a translation block 5 that moves left and right is provided. A linear motor for driving the translation block 5 to move is installed on the guide rail 4. The translation block 5 is rotatably connected to a traction rod 6. At the bottom end of the traction rod 6, a clamping member is provided. The clamping member includes an electric push rod II 61, an upper clamping block 62 and a lower clamping block 63. In the middle of the traction rod 6, the electric push rod II 61 is bolted. On the telescopic rod of the electric push rod II 61, the upper clamping block 62 is connected. At the bottom end of the traction rod 6, the lower clamping block 63 is fixedly connected; Inside the cleaning frame 1, three conveying wheels 7 are installed at intervals. Specifically, the conveying wheels 7 are driven to rotate by a driving motor, and the driving motor is not shown in the figure. Arc-shaped openings 20 are opened on both the left and right sides of the cleaning frame 1 and on the mounting plate 2; After the clamping member clamps the end of the waste wire, the translation block 5 and the clamping member move leftward and pass through each arc-shaped opening 20, thereby pulling the waste wire, and then the waste wire is conveyed by the rotating conveying wheels 7, and the scrubbing plate 3 scrubs the waste wire.

[0031] Reference Figures 2-4 , the friction cleaning machine for plastic recycling further includes a driving mechanism for driving the scrubbing plate 3 to rotate. The driving mechanism includes an arc-shaped rack 31, a connecting block 32, a slider 33, a rotating rod 34 and a gear 35. In the middle of the side where the two mounting plates 2 face each other, arc-shaped racks 31 located at the arc-shaped openings 20 are rotatably connected. The arc-shaped racks 31 all have openings. On the side where the two arc-shaped racks 31 face each other, a pair of connecting blocks 32 are fixedly connected. On the connecting blocks 32, sliders 33 are slidably connected. The front scrubbing plate 3 is fixedly connected to the front two sliders 33, and the rear scrubbing plate 3 is fixedly connected to the rear two sliders 33. A compression spring is fixedly connected between the scrubbing plate 3 and the connecting block 32. Between the front and rear parts of the two mounting plates 2, rotating rods 34 driven by waterproof motors are rotatably connected. On the left and right ends of the rotating rod 34, gears 35 are fixedly connected. The two left gears 35 are a pair, and the two right gears 35 are a pair. The two pairs of gears 35 are respectively engaged with the two arc-shaped racks 31.

[0032] Reference Figure 2 , Figure 3 and Figure 9The driving mechanism also includes a positioning component, which includes an electric push rod 342 and a translation cylinder 343. The middle surface of the front rotating rod 34 has a convex portion 341. A waterproof electric push rod 342 is bolted to the front side of the inner wall of the cleaning frame 1. The telescopic rod of the electric push rod 342 is connected to the translation cylinder 343. The translation cylinder 343 is sleeved on the front rotating rod 34. The translation cylinder 343 is provided with a straight groove 344 for the convex portion 341 to extend into; the translation cylinder 343 has an inclined surface 345 at one end close to the convex portion 341. When the translation cylinder 343 moves, the convex portion 341 is squeezed by the inclined surface 345 so that the convex portion 341 extends into the straight groove 344.

[0033] Initially, the openings of the arc-shaped rack 31 are all facing upward. In the process of recycling the waste electric wires, it is necessary to clean the waste electric wires, place the ends of the waste electric wires on the lower clamping block 63, control the electric push rod 2 61 to drive the upper clamping block 62 to move downward, and the upper clamping block 62 and the lower clamping block 63 clamp the ends of the waste electric wires, and then control the linear motor to drive the translation block 5 to translate to the left along the guide rail 4, drive the traction rod 6 and the clamping piece to move to the left together and pass through each arc-shaped opening 20 and the opening of the arc-shaped rack 31 in turn, so that the waste electric wires pass through the arc-shaped opening 20 and the opening of the arc-shaped rack 31, and the waste electric wires pass through the position between the two brush plates 3. Under the action of the compression spring, the bristles of the brush plate 3 are in close contact with the surface of the waste electric wires, and the traction rod 6 can pull the waste electric wires to the outside of the left side of the cleaning frame 1 through the clamping piece.

[0034] The nozzle on the cleaning frame 1 sprays water in the direction of the waste wires. When the end of the pulled waste wire passes through the arc-shaped opening 20 of the left mounting plate 2, the waterproof motor can be controlled to drive the two rotating rods 34 to rotate in the same direction, driving the four gears 35 to rotate in the same direction. Under the meshing action, the arc-shaped rack 31 can be rotated. When the rotating arc-shaped rack 31 is separated from the front gear 35, the gear 35 rotating at the rear side continues to drive the arc-shaped rack 31 to rotate, and the arc-shaped rack 31 meshes with the front gear 35 again. When the rotating arc-shaped rack 31 separates from the gear 35 on the rear side, the gear 35 rotating on the front side continues to drive the arc-shaped rack 31 to rotate, and the arc-shaped rack 31 meshes with the gear 35 on the rear side again. At least one gear 35 meshes with the arc-shaped rack 31, so that the arc-shaped rack 31 can continue to rotate, and the arc-shaped rack 31 drives the connecting block 32, the slider 33 and the scrubbing plate 3 to rotate together. The scrubbing plate 3 rotates around the periphery of the waste wires, and the surface of the waste wires can be scrubbed by the friction of the bristles.

[0035] After the translation block 5 and the towing rod 6 move to the outside of the left side of the cleaning frame 1, the waste wire is located on the three conveying wheels 7. Control the rotation of the conveying wheels 7. Under the action of friction, the conveying wheels 7 continue to convey the waste wire to the left. With the cooperation of the scrubbing plate 3 and the nozzle, the waste wire can be frictionally cleaned. The waste wire after cleaning can be used for the reproduction of polyvinyl chloride cable material particles, so as to recycle the waste wire. By setting the openings of the arc-shaped opening 20 and the arc-shaped rack 31, the towing rod 6 can automatically tow the waste wire, and the waste wire passes through the cleaning frame 1, reducing the operation of manual intervention and improving the recycling efficiency of the waste wire.

[0036] After a waste wire is cleaned, control the waterproof motor to stop driving the rotating rod 34. The rotating rod 34, the gear 35, the arc-shaped rack 31 and the scrubbing plate 3 stop rotating. If the opening of the arc-shaped rack 31 does not face upward, the convex strip portion 341 is not aligned with the straight groove 344. At this time, control the first electric push rod 342 to drive the translation cylinder 343 to translate to the left. The left-translated translation cylinder 343 squeezes the convex strip portion 341 through the inclined surface 345, so that the convex strip portion 341 rotates to a position aligned with the straight groove 344. The convex strip portion 341 extends into the straight groove 344. The convex strip portion 341 drives the rotating rod 34, the gear 35, the arc-shaped rack 31 and the scrubbing plate 3 to rotate together until the opening of the arc-shaped rack 31 faces upward and the scrubbing plate 3 returns to the initial position. Then control the first electric push rod 342 to drive the translation cylinder 343 to move rightward and reset, and the convex strip portion 341 leaves the straight groove 344. In this way, the opening of the arc-shaped rack 31 can face upward through the translated translation cylinder 343, automatically and effectively positioning the position of the arc-shaped rack 31 and ensuring the smooth progress of the subsequent towing work of the waste wire.

[0037] Embodiment 2: On the basis of Embodiment 1, refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 , the friction cleaning machine for plastic recycling further includes a first fixing block 601, a sliding cylinder 602, a convex block 604 and a contact plate 605. The towing rod 6 includes a rotating shaft portion 60 at its upper end. The towing rod 6 rotates around the rotating shaft portion 60. A first fixing block 601 is fixedly connected to the left side of the translation block 5. A left-right sliding sliding cylinder 602 is provided on the first fixing block 601. The sliding cylinder 602 is sleeved outside the left end of the rotating shaft portion 60. A threaded groove 603 is formed on the surface of the left end of the rotating shaft portion 60. A convex block 604 connected to the inner wall of the sliding cylinder 602 is located in the threaded groove 603. A contact plate 605 is connected to the left end of the guide rail 4. When the translation block 5 drives the first fixing block 601 and the sliding cylinder 602 to move to the left, the sliding cylinder 602 will contact the contact plate 605. The translation block 5 and the first fixing block 601 continue to move to the left. With the cooperation of the convex block 604 and the threaded groove 603, the towing rod 6 can rotate around the rotating shaft portion 60.

[0038] Refer to Figure 2 ,Figure 5 and Figure 8 The friction cleaning machine for plastic recycling further includes a sliding rod 81, a hinged rod 82, a vertical rod 83, a second fixing block 84, a sliding column 85 and a pressing wheel 86. A sliding rod 81 that slides left and right is provided at the lower part of the contact plate 605. The first fixing block 601 that moves leftward will contact the sliding rod 81. The front side and the rear side of the inner wall of the cleaning frame 1 are both fixedly connected with a second fixing block 84. The second fixing block 84 is provided with a sliding column 85 that slides back and forth. A first return spring is fixedly connected between the sliding column 85 and the second fixing block 84. One end of the two sliding columns 85 close to each other is rotatably connected with a pressing wheel 86. The top of the sliding column 85 is fixedly connected with a vertical rod 83. A hinged rod 82 is rotatably connected between the top ends of the two vertical rods 83 and the sliding rod 81.

[0039] When the translation block 5 and the traction rod 6 move leftward, the traction rod 6 drives the first fixing block 601 and the sliding cylinder 602 to move leftward together. When the first fixing block 601 contacts the sliding rod 81, the first fixing block 601 that continues to move leftward will push the sliding rod 81 to move leftward. Since the vertical rod 83 and the sliding column 85 can only move in the front-back direction, under the transmission of the hinged rod 82, the sliding rod 81 that moves leftward can make the two vertical rods 83 approach each other in the front-back direction. The sliding column 85 slides on the second fixing block 84, and the first return spring deforms. The pressing wheel 86 approaches the waste wire, and the pressing wheel 86 closely adheres to the surface of the waste wire under the action of the second return spring. Subsequently, the sliding cylinder 602 that moves leftward contacts the contact plate 605, and the sliding cylinder 602 stops moving. However, the translation block 5, the traction rod 6 and the first fixing block 601 continue to move leftward. The traction rod 6 and the clamping member are located outside the cleaning frame 1. The first fixing block 601 and the sliding cylinder 602 move relatively. The rotating shaft part 60 of the traction rod 6 and the convex block 604 move relatively. Since the convex block 604 is located in the thread groove 603, the traction rod 6 and the clamping member can rotate upward by 90 degrees with the rotating shaft part 60 as the axis to avoid blocking the subsequent waste wire and improve the operation convenience. During the subsequent friction cleaning process of the waste wire, the pressing wheel 86 plays a role in limiting the waste wire.

[0040] Embodiment 3: On the basis of Embodiment 2, refer to Figure 1 、 Figure 10 and Figure 11, the friction cleaning machine for plastic recycling further includes a feeding frame 91, a first vertical plate 92, a second vertical plate 93, a lower limiting wheel 94, a lifting block 95, an upper limiting wheel 96, an outer cylinder 97 and a pin 98. A feeding frame 91 is bolted to the right side of the cleaning frame 1. A first vertical plate 92 and a second vertical plate 93 are fixedly connected to the right side of the feeding frame 91. A lower limiting wheel 94 is rotatably connected to the top end of the second vertical plate 93. A vertically slidable lifting block 95 is provided in the upper part of the first vertical plate 92. An upper limiting wheel 96 located directly above the lower limiting wheel 94 is rotatably connected to the lifting block 95. An outer cylinder 97 that slides back and forth is provided on the lifting block 95. A second return spring is connected between the outer cylinder 97 and the lifting block 95. A pin 98 is connected to an eccentric position at the rear end of the outer cylinder 97. A jack for inserting the pin 98 is opened in the upper part of the first vertical plate 92.

[0041] Before cleaning the waste wires, first manually pull the outer cylinder 97 forward, driving the pin 98 to move forward, deforming the second return spring, causing the pin 98 to leave the jack, pushing the outer cylinder 97 upward, driving the pin 98, the lifting block 95 and the upper limiting wheel 96 to move upward, placing the left end of the waste wire on the lower limiting wheel 94, then pushing the outer cylinder 97 downward to reset, driving the pin 98, the lifting block 95 and the upper limiting wheel 96 to move downward, releasing the outer cylinder 97, the second return spring restores, driving the outer cylinder 97 and the pin 98 to move backward, and the pin 98 is inserted back into the jack to limit the outer cylinder 97. At this time, both the upper limiting wheel 96 and the lower limiting wheel 94 are in contact with the surface of the waste wire. Manually pull the left end of the waste wire. When the waste wire is knotted, it is impossible to continue pulling the waste wire, reminding people that they need to deal with the knotted part of the waste wire. The processed waste wire is put into the feeding frame 91 for temporary storage, so as to ensure the smooth progress of the subsequent conveying and cleaning work of the waste wire.
