Description

Technical Field

[0001] This invention relates to the field of PE water supply pipe manufacturing technology, and more specifically, to a PE water supply pipe processing device. Background Technology

[0002] Because the PE pipe extruder extrudes high-temperature plastic, it needs to be pulled by a large-diameter old PE pipe to enter the vacuum forming chamber for shaping. In the existing technology, the high-temperature plastic is squeezed by hand-held tools to wrap the extruded high-temperature plastic around the large-diameter old PE pipe. This is not only time-consuming and labor-intensive, but also cannot guarantee that the high-temperature plastic is completely attached to the outer ring surface of the large-diameter old PE pipe. Furthermore, when wrapping the large-diameter old PE pipe, because the 7a-die orifice is ring-shaped and the high-temperature plastic extruded by the PE pipe extruder is in a plastic viscous flow state, it will continue to converge downwards. When there is a lot of high-temperature plastic at the bottom of the large-diameter old PE pipe, it will cause the large-diameter old PE pipe to be unable to pull the extruded high-temperature plastic into the vacuum forming chamber.

[0003] Furthermore, after a long period of shutdown, the high-temperature plastic on the outermost part of the die of a PE pipe extruder that produces large-diameter PE pipes will harden and become unusable, requiring removal. However, manually removing the high-temperature plastic from the outermost part of the die and then smoothing the die with sandpaper takes a long time.

[0004] Furthermore, before wrapping the high-temperature plastic extruded from the PE pipe extruder around large-diameter recycled PE pipes, the recycled PE pipes need to be preheated to increase their viscosity and prevent the high-temperature plastic from automatically detaching during traction. In existing technologies, preheating is done manually. This requires operators to wear gloves, hold the high-temperature plastic extruded from the PE pipe extruder, cut it, and then wrap the cut high-temperature plastic around the large-diameter recycled PE pipe for preheating. This process needs to be repeated multiple times to complete the preheating of the large-diameter recycled PE pipe. This not only takes a lot of time, but the high-temperature plastic can also easily burn operators, posing a certain safety hazard. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, which involves manually squeezing high-temperature plastic with hand tools to wrap the extruded high-temperature plastic around a large-diameter old PE pipe. This process is not only time-consuming and labor-intensive, but also fails to ensure that the high-temperature plastic completely adheres to the outer surface of the large-diameter old PE pipe. The invention provides a processing device that can replace manual labor in wrapping high-temperature plastic around a large-diameter old PE pipe and ensure that the plastic completely adheres to the outer surface of the pipe, thereby reducing the burden on workers and improving production efficiency.

[0016] Preferably, the lower part of the inner ring surface of the second ring plate and the outer ring surface of the cylinder are both wavy.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The PE water supply pipe processing device obtained by the present invention uses two small sliders to slide back and forth in an arc-shaped groove, which carries the front support block to move forward and upward continuously, and the rear support block to move backward and upward continuously. This prevents a large amount of high-temperature plastic from accumulating on the lower part of the outer ring surface of large-diameter old PE pipes, and facilitates the subsequent entry of high-temperature plastic into the vacuum forming box.

[0019] The PE water supply pipe processing device of the present invention, through the above-designed method, uses a traction rod to carry a steel cable and a corresponding number of steel plates around a large-diameter old PE pipe, which then rests on the high-temperature plastic on the outer ring surface of the old PE pipe. The steel cable is then tightened, causing the corresponding number of steel plates connected to the steel cable to move closer together, so that the high-temperature plastic is completely adhered to the outer ring surface of the old PE pipe. This avoids the problem of poor adhesion between the high-temperature plastic and the old PE pipe, and reduces the workload of the operators.

[0020] The PE water supply pipe processing device designed in this invention uses a continuously rotating cross cone cutter to shred hardened plastic, which then smoothly enters the mold opening along with the auger, semi-circular cover, spring telescopic column, and grinding strip. The shredded hardened plastic is then transported out by the rotating auger, reducing the workload of operators and improving work efficiency.

[0021] The PE water supply pipe processing device of the present invention, as designed above, uses an auger, a cross cone cutter, and a semi-circular cover to perform circular motion. The serrated blades on the auger scrape off the hardened plastic on the outermost side of the die opening. The auger and the semi-circular cover work together to convey the scraped hardened plastic outward. At the same time, the grinding strip also grinds the inner wall of the die opening during the circular motion, making it smooth. This facilitates the subsequent discharge of PE pipe from the extruder, greatly saves manpower, reduces the workload of operators, and improves work efficiency.

[0022] The PE water supply pipe processing device of the present invention, as designed above, receives the high-temperature plastic extruded by the PE pipe extruder through the annular groove formed by the second annular plate and the cylinder. The extruded high-temperature plastic is then cut by a cutter. The cut high-temperature plastic is then pushed to the outer ring surface of a large-diameter old PE pipe. The rollers make circumferential motion so that the cut high-temperature plastic adheres tightly to the outer ring surface of the large-diameter old PE pipe. The high-temperature plastic preheats the large-diameter old PE pipe. This eliminates the need for operators to manually wrap the high-temperature plastic around the outer ring surface of the large-diameter old PE pipe, thus reducing the workload of operators and eliminating safety hazards.

[0047] The front-mounted pushing assembly includes a second sliding plate 301, a third linear electric slide rail 302, a third electric slider 303, a limiting block 304, a sliding rod 305, a small slider 306, a support block 307, and a sliding column 308; the second sliding plate 301 is fixedly connected to the right side of the upper surface of the front second mounting plate 106; an arc-shaped sliding groove 301a is opened on the second sliding plate 301; the third linear electric slide rail 302 is bolted to the left side of the second sliding plate 301; the third electric slider 303 is slidably connected to the outer surface of the third linear electric slide rail 302; a limiting block 304 is fixedly connected to the third electric slider 303; the limiting block 304 extends through...

[0048] The rotations described below refer to views from front to back, from top to bottom, and from right to left. During use, first place the PE water pipe processing device between the vacuum forming box 5 and the PE pipe extruder 7. Figure 1 As shown, the operator cleans the hardened plastic on the outermost side of the die opening 7a of the PE pipe extruder 7. After cleaning, the inner wall of the die opening 7a is polished to facilitate the subsequent discharge of the PE pipe extruder 7. Then, a large-diameter used PE pipe 6 is placed into the vacuum shaping box 5 and conveyed to the right through the vacuum shaping box 5 until the right end of the large-diameter used PE pipe 6 is removed from the vacuum shaping box 5. The operator then controls the vacuum shaping box 5 to stop conveying the large-diameter used PE pipe 6. The operator controls the PE pipe extruder 7 to extrude a portion of high-temperature plastic, cuts it off, and places it on the outer ring surface of the large-diameter used PE pipe 6 for preheating. After the large-diameter used PE pipe 6 is preheated...

[0049] The vacuum shaping box 5 moves to the right along with the large-diameter used PE pipe 6. Once the large-diameter used PE pipe 6 is close to the left side of the PE pipe extruder 7, the vacuum shaping box 5 stops moving. Then, the second electric slider 105 moves backward on the outer surface of the second linear electric slide rail 104. The two second electric sliders 105, along with the second mounting plate 106, the first slide rail 201, the semi-circular toothed ring 202, the first motor 203, the spur gear 204, the traction rod 2, the limit assembly, and the steel... Cable 3, steel plate 4, and the front push assembly move backward together. At the same time, the rear second electric slider 105 is controlled to move forward on the outer surface of the rear second linear electric slide rail 104. The two rear second electric sliders 105, along with the rear second mounting plate 106, the rear first slide plate 201, the rear semi-circular toothed ring 202, and the rear push assembly, move forward together until the two first slide plates 201, the two semi-circular toothed rings 202, and the two push assemblies are all merged. Then, the four second electric sliders 105 are controlled to stop moving.

[0050] When the two pushing components merge, the PE pipe extruder 7 is turned on, and high-temperature plastic is extruded from the die orifice 7a. Since the die orifice 7a is annular and the extruded high-temperature plastic is in a plastic viscous flow state, the high-temperature plastic extruded from the die orifice 7a will slowly flow downward. Then, because the large-diameter PE old pipe 6 is located on the left side of the PE pipe extruder 7 and the two support blocks 307 are also located below the die orifice 7a, the large-diameter PE old pipe 6 will catch part of the high-temperature plastic extruded from the upper part of the die orifice 7a, and the two support blocks 307 will catch a small part of the high-temperature plastic from the lower part of the die orifice 7a and make it adhere to the outer ring surface of the large-diameter PE old pipe 6. The high-temperature plastic that is not caught will continue to flow downward.

[0051] At this time, the two pushing components are controlled to operate synchronously. Taking the front pushing component as an example, the third electric slider 303 is controlled to reciprocate back and forth on the outer surface of the third linear electric slide rail 302. When the third electric slider 303 moves forward, it will drive the limiting block 304, the sliding rod 305, the small slider 306, the support block 307, and the sliding column 308 to move forward together. The small slider 306 is restricted by the arc-shaped slide groove 301a and moves forward and upward along the trajectory of the arc-shaped slide groove 301a, causing the sliding rod 305, the support block 307, and the sliding column 308 to also move forward and upward together. This forces the sliding rod 305 to slide upward within the limiting block 304, causing the support block 307 to move forward and upward from below the large-diameter old PE pipe 6. During the movement of the support block 307, it will push the high-temperature plastic flowing downward in front of the support block 307 forward and upward, so that the high-temperature plastic is tightly attached to the outer ring surface of the large-diameter old PE pipe 6, preventing high temperature from rising. The warm plastic continues to flow downwards until the small slider 306 moves to the end of the arc-shaped chute 301a. When the third electric slider 303 moves backwards, it will drive the connected components to move together, allowing the support block 307 to move back below the large-diameter old PE pipe 6. Through the continuous reciprocating motion of the third electric slider 303, the downward-flowing high-temperature plastic can be continuously pushed upwards. The rear push component also operates synchronously with the front push component, moving another support block 307 backwards and upwards, pushing the downward-flowing high-temperature plastic behind the support block 307 backwards and upwards, so that the high-temperature plastic adheres tightly to the outer ring surface of the large-diameter old PE pipe 6. The continuous reciprocating motion of the two support blocks 307 can prevent a large amount of high-temperature plastic extruded from the mold opening 7a from accumulating at the lower part of the large-diameter old PE pipe 6, which would cause too much high-temperature plastic at the lower part of the outer ring surface of the large-diameter old PE pipe 6 and prevent it from entering the vacuum forming box 5.

[0052] As the support block 307 continues its reciprocating motion, the vacuum shaping box 5, carrying the large-diameter old PE pipe 6 and its high-temperature plastic, slowly moves to the left. When the large-diameter old PE pipe 6, carrying its outer ring of high-temperature plastic, moves between the two semi-circular toothed rings 202, the vacuum shaping box 5 stops moving. The operator then wraps the first end of the steel cable 3 around the traction rod 2, and controls the output shaft of the first motor 203 to rotate clockwise, driving the spur gear 204 to rotate. The spur gear 204 then drives the two semi-circular toothed rings 202 and the traction rod... When rod 2 rotates counterclockwise, the two semi-circular toothed rings 202 rotate on the two first sliding plates 201. The steel cable 3 is wound on the traction rod 2, and it will also rotate along with the steel cable 3 and the corresponding number of steel plates 4. After the traction rod 2 rotates above the second limit rod 210, the steel cable 3 and the corresponding number of steel plates 4 that rotate along with it will surround the large-diameter old PE pipe 6 once, and the corresponding number of steel plates 4 will fall on the high-temperature plastic on the outer ring surface of the large-diameter old PE pipe 6, controlling the output shaft of the first motor 203 to stop rotating.

[0053] At this point, the operator unties the first end of the steel cable 3 from the traction rod 2, and winds both ends of the steel cable 3 onto the L-shaped rod 213. Then, the operator controls the first electric push rod 207 and the second electric push rod 209 to push out, moving the first limit rod 208 and the second limit rod 210 backwards. The first limit rod 208 moves backwards close to the end of the steel cable 3, forcing the steel sheet 4 at the end of the steel cable 3 to press against the high-temperature plastic. Similarly, the second limit rod 210 moves backwards close to the first end of the steel cable 3, forcing the steel sheet 4 at the first end of the steel cable 3 to also press against the high-temperature plastic. Then, the operator controls the output shaft of the second motor 211 to rotate clockwise, causing the winding wheel 212 to rotate with the L-shaped rod 213, winding up the steel cable 3 wound on the L-shaped rod 213. As the steel cable 3 contracts, the corresponding number of steel sheets 4 connected to the steel cable 3 move closer together, squeezing the high-temperature plastic on the outer ring of the large-diameter PE old pipe 6 until the high-temperature plastic completely adheres to the large-diameter PE old pipe 6. After the outer ring surface, to prevent the high-temperature plastic from not fitting tightly with the large-diameter PE old pipe 6, the output shaft of the second motor 211 is controlled to rotate counterclockwise, which unwinds the steel cable 3 and the corresponding number of steel sheets 4 pressing on the high-temperature plastic. Then, the operator unwraps the steel cable 3 wrapped around the L-shaped rod 213, and then controls the first electric push rod 207 and the second electric push rod 209 to retract, driving the connected components to reset. The operator then collects the steel cable 3 and the corresponding number of steel sheets 4. Next, the operator controls the vacuum shaping box 5 to transport the large-diameter PE old pipe 6 to the left. The high-temperature plastic extruded by the PE pipe extruder 7 is pulled into the vacuum shaping box 5 for shaping through the large-diameter PE old pipe 6. At the same time, the vacuum shaping box 5 moves to the right and closer to the PE pipe extruder 7 to shorten the distance between the vacuum shaping box 5 and the PE pipe extruder 7, so that the high-temperature plastic can enter the vacuum shaping box 5 later. Then, all components are controlled to reset. Example

[0054] Based on Example 1, such as Figure 7-8As shown, the cleaning system includes a square tube frame 401, a motion platform 402, a first annular plate 403, a first annular electric slide rail 404, a first arc-shaped slide block 405, a cleaning assembly, and a preheating assembly. Two square tube frames 401 are fixedly connected to the right side of the upper surface of the first mounting plate 103. Each of the two square tube frames 401 is bolted to a motion platform 402 on its opposite side, and the two motion platforms 402 are symmetrically distributed front and back. The moving parts of the two motion platforms 402 are jointly fixed to the first annular plate 403. The motion platform 402 can carry the first annular plate 403, the first annular electric slide rail 404, and the first arc-shaped slide block 405. The arc-shaped slide block 405, the cleaning component, and the preheating component move up or down to the required position; the right side of the first annular plate 403 is bolted to the first annular electric slide rail 404; the outer surface of the first annular electric slide rail 404 is slidably connected to two first arc-shaped slide blocks 405; each of the two first arc-shaped slide blocks 405 is connected to a cleaning component, and the two cleaning components are symmetrically distributed about the center of the first annular plate 403. The two first arc-shaped slide blocks 405 each carry a cleaning component to clean the hardened plastic on the outermost side of the mold opening 7a; the left side of the first annular plate 403 is connected to the preheating component.

[0055] The rear-mounted cleaning assembly includes a third motor 406, a fixing plate 407, a fourth motor 408, an auger 409, a cross-shaped conical cutter 410, a semi-circular cover 411, a spring-loaded telescopic column 412, and a grinding strip 413. The third motor 406 is bolted to the first arc-shaped slide block 405 at the rear. The output shaft of the third motor 406 is fixedly connected to the fixing plate 407. The fourth motor 408 is bolted to the left side of the fixing plate 407. The output shaft of the fourth motor 408 passes through the fixing plate 407 and is rotatably connected to it. The output shaft of the fourth motor 408 is fixedly connected to the auger 409. A cross-shaped conical cutter 410 is fixedly connected to the right side of the auger 409; the cross-shaped conical cutter 410 is conical to facilitate the removal of hardened plastic. A semi-circular cover 411 is fixedly connected to the right side of the fixing plate 407; the inner arc surface of the semi-circular cover 411 is made of smooth material to prevent entanglement. High-temperature plastic residue; the auger 409 is located inside the semi-circular cover 411; four spring telescopic columns 412 are fixedly connected to the outer ring surface of the semi-circular cover 411, and the four spring telescopic columns 412 are symmetrically distributed in pairs; the telescopic ends of the two upper spring telescopic columns 412 are jointly fixedly connected to a grinding strip 413; the telescopic ends of the two lower spring telescopic columns 412 are jointly fixedly connected to another grinding strip 413. When the grinding strip 413 enters the mold opening 7a, under the action of the corresponding spring telescopic columns 412, the grinding strip 413 better fits the inner wall of the mold opening 7a for grinding; each grinding strip 413 is provided with a guide part 413a. When the guide part 413a contacts the mold opening 7a, it forces the spring telescopic column 412 to compress, allowing the grinding strip 413 to smoothly enter the mold opening 7a.

[0056] The blades of the auger 409 are equipped with serrated blades 409a for scraping off hardened plastic.

[0057] When the PE pipe extruder 7 is shut down for an extended period, the plastic on the outermost edge of the die opening 7a hardens and becomes unusable. Manually removing this hardened plastic and sanding the die opening 7a smooth is time-consuming. Therefore, controlling the first electric slider 102 to move to the left on the outer surface of the first linear electric slide rail 101, along with the four first electric sliders 102, drives the first mounting plate 103, the second linear electric slide rail 104, the second electric slider 105, the second mounting plate 106, the power assembly, the traction rod 2, the limit assembly, the steel cable 3, the steel plate 4, and the push assembly. The components and cleaning system move to the left together. After the cleaning system is moved between the vacuum shaping box 5 and the PE pipe extruder 7, the four first electric sliders 102 are stopped. Then, the two motion platforms 402 are operated. The motion unit moves the first annular plate 403, the first annular electric slide rail 404, the first arc-shaped slide block 405, the cleaning component and the preheating component downward together. The first annular plate 403, the first annular electric slide rail 404, the first arc-shaped slide block 405, the cleaning component and the preheating component are moved to the left of the PE pipe extruder 7, and a collection box is placed below the PE pipe extruder 7.

[0058] The two cleaning components operate synchronously. Taking the rear cleaning component as an example, the output shaft of the third motor 406 is controlled to rotate clockwise, causing the fixed plate 407, the fourth motor 408, the auger 409, the cross cone cutter 410, the semi-circular cover 411, the spring telescopic column 412, and the grinding strip 413 to rotate 90 degrees together, changing the cleaning component from a vertical to a horizontal position, with the cross cone cutter 410 positioned to the left of the mold opening 7a. Then, the output shaft of the fourth motor 408 is controlled to rotate, causing the auger 409 and the cross cone cutter 410 to rotate together. Then, the four first electric sliders 102 are controlled to move the connected components to the right. The continuously rotating cross cone cutter 410 removes the hardened plastic on the outermost side of the mold opening 7a. Then, the guide parts 413a of the two grinding strips 413 contact the mold opening 7a, forcing the corresponding spring telescopic column 412 to compress, thus... The two polishing strips 413 move towards each other, and under the action of the cross conical cutter 410, the auger 409, the semi-circular cover 411, the spring telescopic column 412, and the polishing strips 413 smoothly enter the mold opening 7a. During the movement, the auger 409 and the semi-circular cover 411 cooperate with each other. The continuously rotating auger 409 continuously conveys the hardened plastic that is shredded by the cross conical cutter 410 to the left. After it is conveyed out of the mold opening 7a, it will fall into the collection box below. After the two polishing strips 413 are completely inside the mold opening 7a, the four first electric sliders 102 are controlled to stop moving. The other cleaning component also operates in the same way as the cleaning component behind it. The continuously rotating cross conical cutter 410 shreds the hardened plastic, and the auger 409, the semi-circular cover 411, the spring telescopic column 412, and the polishing strips 413 smoothly enter the mold opening 7a.

[0059] Simultaneously, the first arc-shaped slide block 405 is controlled to rotate counterclockwise on the outer surface of the first annular electric slide rail 404. Each of the two first arc-shaped slide blocks 405 drives a cleaning component to rotate counterclockwise. During the movement, the auger 409 in the two cleaning components cooperates with the semi-circular cover 411. The serrated blade 409a on the auger 409 continuously rotates to scrape off the hardened plastic on the outermost side of the mold opening 7a and convey it to the left into the collection box below. After one revolution, the hardened plastic on the outermost side of the mold opening 7a will be completely cleaned. Meanwhile, the four grinding strips 413 are moving... During the process, under the action of eight spring telescopic columns 412, they unfold and stick tightly to the inner wall of the mold opening 7a to polish the hardened plastic remaining on the inner wall of the mold opening 7a until the inner wall of the mold opening 7a is polished smooth, which helps the high-temperature plastic of the subsequent PE pipe extruder 7 to be extruded from the mold opening 7a. When the two first arc-shaped slides 405 return to the initial position, the two first arc-shaped slides 405 are controlled to stop moving. Then, the four first electric sliders 102 are controlled to drive the connected parts to move to the left, moving the two cleaning components out of the mold opening 7a. Then, the two cleaning components are controlled to automatically reset.

[0060] The large-diameter used PE pipe 6 is preheated manually, and the high-temperature plastic extruded by the PE pipe extruder 7 is manually wrapped around the outer ring of the large-diameter used PE pipe 6. The high-temperature plastic extruded by the PE pipe extruder 7 is brought into the vacuum shaping box 5 for shaping by the traction of the large-diameter used PE pipe 6. Example

[0061] Based on Example 2, such as Figure 9-10 As shown, the preheating assembly includes a second annular electric slide rail 501, a second arc-shaped slide block 502, a second annular plate 503, a first annular plate 504, a third electric push rod 505, a cylinder 506, a second annular plate 507, a fourth electric push rod 508, a blade holder 509, a cutter 510, and a compaction assembly; the second annular electric slide rail 501 is bolted to the left side of the first annular plate 403; three second arc-shaped slide blocks 502 are slidably connected to the outer surface of the second annular electric slide rail 501, and the three second arc-shaped slide blocks 502 are arranged in a ring array; the three second arc-shaped slide blocks 502 are jointly fixed to the second annular plate 503; the first annular plate 504 is fixed to the left side of the inner annular surface of the second annular plate 503; three third electric push rods 505 are installed on the outer wall of the second annular plate 503, and the three third electric push rods 505 are arranged in a ring array; the three third electric push rods The telescopic part of 505 is fixedly connected to a cylinder 506; the outer ring surface of the cylinder 506 is inserted into the first annular plate 504; the right side of the inner ring surface of the cylinder 506 is fixedly connected to a second annular plate 507, the inner ring surface of the second annular plate 507 is provided with a number of grooves 507a, and the grooves 507a are arranged in a ring array. When the high-temperature plastic on the outer ring surface of the large-diameter old PE pipe 6 is scraped off by the second annular plate 507, a small amount of high-temperature plastic remains on the outer ring surface of the large-diameter old PE pipe 6, increasing the stickiness of the large-diameter old PE pipe 6; a fourth electric push rod 508 is fixedly connected to the second arc-shaped slide 502 below; a knife holder 509 is fixedly connected to the telescopic part of the fourth electric push rod 508; a cutter 510 is fixedly connected to the knife holder 509, and the cutter 510 is made of high-temperature resistant metal material; a rolling assembly is connected to the upper part of the outer wall of the second annular plate 503; the rolling assembly is staggered with the three third electric push rods 505.

[0062] The rolling assembly includes a mounting block 511, a fifth electric push rod 512, a fixed seat 513, and a roller 514. The mounting block 511 is fixedly connected to the upper part of the outer wall of the second annular plate 503. The fifth electric push rod 512 is fixedly connected to the mounting block 511. The telescopic part of the fifth electric push rod 512 is fixedly connected to the fixed seat 513. The roller 514 is rotatably connected to the fixed seat 513. The outer surface of the roller 514 is made of high-temperature resistant and non-stick material. The roller 514 rolls the high-temperature plastic on the outer ring surface of the large-diameter old PE pipe 6, so that the high-temperature plastic is completely adhered to the outer ring surface of the large-diameter old PE pipe 6 for preheating.

[0063] The lower part of the inner ring surface of the second ring plate 503 and the outer ring surface of the cylinder 506 are both wavy, which reduces the contact area between the high-temperature plastic and the second ring plate 503 and the cylinder 506, and prevents the high-temperature plastic from sticking to the second ring plate 503 and the cylinder 506. In addition, the second ring plate 503 and the cylinder 506 are both made of high-temperature resistant materials.

[0064] Once the die opening 7a of the PE pipe extruder 7 is cleaned, the four first electric sliders 102 are controlled to move the connected components to the left. After the cleaning system is positioned between the vacuum forming box 5 and the PE pipe extruder 7, the four first electric sliders 102 are stopped. Then, the two motion platforms 402 are controlled to move, driving the connected components downwards through the motion units. This moves the first annular plate 403, the first annular electric slide rail 404, the first arc-shaped slide block 405, the cleaning assembly, and the preheating assembly to the left of the PE pipe extruder 7. Finally, the PE pipe extruder 7 is started for continuous operation. The temperature is increased until the PE pipe extruder 7 reaches 230 degrees Celsius. The operator then controls the vacuum shaping box 5 to convey the large-diameter used PE pipe 6 to the right. Once the right end of the large-diameter used PE pipe 6 is inside the preheating assembly, the vacuum shaping box 5 stops conveying the pipe, and a collection box is placed below the large-diameter used PE pipe 6. Then, the four first electric sliders 102 are controlled to move their connected components to the right until the cutter 510 approaches the PE pipe extruder 7, and the annular groove formed by the second annular plate 503 and the cylinder 506 is aligned with the die opening 7a. At this point, the four first electric sliders 102 are stopped moving. Next, the PE pipe extruder 7 is controlled to extrude high-temperature plastic from the die opening 7a, allowing the extruded high-temperature plastic to enter the annular groove formed by the second annular plate 503 and the cylinder 506. After enough high-temperature plastic is extruded, the PE pipe extruder 7 is controlled to stop discharging. Then, the fourth electric push rod 508 is controlled to retract, driving the cutter holder 509 and the cutter 510 to move upward, allowing the cutter 510 to insert into the extruded high-temperature plastic. Then, the second arc-shaped slide block 502 is controlled to make clockwise circular motion on the outer surface of the second annular electric slide rail 501. The three second arc-shaped slide blocks 502, along with the second annular plate 503 and the first annular plate 506, move clockwise. Plate 504, third electric push rod 505, cylinder 506, second annular plate 507, fourth electric push rod 508, blade holder 509, cutter 510 and crushing assembly move clockwise in a circular motion. After the three second arc-shaped slides 502 move one revolution with the cutter 510, the high-temperature plastic extruded by the PE pipe extruder 7 is cut by the cutter 510, so that the cut part of the high-temperature plastic falls into the annular groove formed by the second annular plate 503 and cylinder 506. The fourth electric push rod 508 is controlled to push out, driving the connected parts to move downward, so that the cutter 510 withdraws from the high-temperature plastic.

[0065] After the high-temperature plastic extruded from the PE pipe extruder 7 is cut, the four first electric sliders 102 are controlled to move the connected components to the left, moving the cut high-temperature plastic to the right end of the large-diameter used PE pipe 6. The four first electric sliders 102 are then stopped, and the three third electric push rods 505 are pushed out, moving the cylinder 506 and the second annular plate 507 to the left. Under the obstruction of the first annular plate 504, the high-temperature plastic that was originally on the outer ring surface of the cylinder 506 falls on the upper part of the outer ring surface of the large-diameter used PE pipe 6, while the high-temperature plastic on the inner ring of the second annular plate 503 remains stationary. Then, the fifth electric push rod 512 is pushed out, moving the fixed seat 513 and the roller 514 downward, so that the roller 514 presses on the high-temperature plastic of the large-diameter used PE pipe 6. The three second arc-shaped slides 502 are then controlled to move the connected components in a clockwise circular motion, so that the roller 514 presses on the cut high-temperature plastic. The high-temperature plastic is rolled around the cut piece, making it adhere more tightly to the outer ring surface of the large-diameter old PE pipe 6. The high-temperature plastic on the inner ring of the second annular plate 503 also adheres tightly to the outer ring surface of the large-diameter old PE pipe 6. The cut high-temperature plastic preheats the right end of the large-diameter old PE pipe 6. After preheating for a period of time, the three third electric push rods 505 are controlled to retract, driving the connected parts to move to the right. The high-temperature plastic on the outer ring surface of the large-diameter old PE pipe 6 is scraped to the right by the second annular plate 507. After the high-temperature plastic is removed from the large-diameter old PE pipe 6, it will fall into the collection box below. The inner ring surface of the second annular plate 507 is provided with several grooves 507a, so that a small amount of high-temperature plastic will remain on the outer ring surface of the large-diameter old PE pipe 6, increasing the adhesion of the outer ring surface of the large-diameter old PE pipe 6, which is convenient for subsequent high-temperature plastic wrapping. The connected parts in the preheating component are controlled to automatically reset.

[0066] After the high-temperature plastic used for preheating on the large-diameter PE old pipe 6 is scraped off, the process is repeated multiple times according to the working principle described above. After the large-diameter PE old pipe 6 is preheated, all components are automatically reset. Then, the vacuum shaping box 5 is controlled to bring the large-diameter PE old pipe 6 close to the PE pipe extruder 7, allowing the PE pipe extruder 7 to discharge material. The high-temperature plastic is manually wrapped completely around the large-diameter PE old pipe 6. Through the traction of the large-diameter PE old pipe 6, the high-temperature plastic extruded by the PE pipe extruder 7 is brought into the vacuum shaping box 5 for shaping.

[0067] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
