Abstract
Description
Technical Field
[0001] This invention belongs to the field of PE pipe processing technology, and in particular relates to a quantitative cutting device and method for PE pipe production. Background Technology
[0002] Polyethylene (PE) pipes are thermoplastic pipes made from polyethylene resin, primarily including high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE). These pipes are characterized by chemical corrosion resistance, high dielectric strength, and strong impact resistance, and can be used in environments ranging from -70℃ to 40℃. However, they are sensitive to corrosion from chemicals such as concentrated nitric acid, xylene, and carbon tetrachloride. Their lightweight and flexible material makes them widely used in urban water supply, gas transmission, agricultural irrigation, and drainage systems, gradually replacing traditional steel and concrete pipes.
[0003] During the processing and production of PE pipes, quantitative cutting is required to meet actual usage needs. However, existing cutting equipment lacks stabilizing devices on both sides of the cut, causing radial offset during the cutting process. This affects the flatness of the cut end, thus impacting the quality of the cut pipe. Furthermore, the cut PE pipe ends are often uneven, further affecting the overall quality of the processed PE pipe. Therefore, we provide a quantitative cutting device and method for PE pipe production to solve the aforementioned problems. Summary of the Invention
[0004] The purpose of this invention is to provide a quantitative cutting device and method for PE pipe production. By controlling the alternating operation of the incomplete toothed ring and the second electromagnet, the sleeve drives the PE pipe to reciprocate. At the same time, when the second arc-shaped clamping plate clamps the PE pipe, the two grinding discs move to a position concentrically aligned with both ends of the PE pipe. During the reciprocating rotation of the PE pipe, its ends continuously rub against the corresponding grinding discs, thereby completing the end grinding operation, improving the flatness of the cut end face and the cutting quality. In addition, the two sides of the PE pipe at the cutting point are fixed before the cutting operation to prevent it from shifting in the radial direction, which would affect the flatness of the cross-section. This solves the problem in existing cutting equipment where the lack of stabilizing devices on both sides of the cutting point causes radial shift during the cutting process, affecting the flatness of the cutting end and thus the quality after cutting. It also addresses the problem of uneven ends of the cut PE pipe, which also affects the quality of the processed PE pipe.

[0014] This invention also includes: a quantitative cutting method for PE pipe production, comprising the following steps: S01: First, the PE pipe is passed through the guide tube from the loading platform and extended onto the conveyor belt. Then, the conveyor belt is rotated intermittently to deliver the PE pipe to the cutting assembly in a quantitative manner.
[0015] S02: Next, control the cutting assembly to move downwards so that the two arc plates can be pre-fixed synchronously on both sides of the PE pipe cutting point. Then, continue to control the laser cutting machine to move downwards to achieve quantitative cutting of the PE pipe.
[0016] S03: Subsequently, by continuing to control the PE pipe to continue feeding to directly below the cutting component, at the same time, the cut PE pipe is pushed onto the grinding component. By controlling the second arc-shaped clamp to move downward, it is clamped. At the same time, the two grinding discs are controlled to move to both ends of the PE pipe, and then the PE pipe is controlled to rotate back and forth, so that the cut PE pipe continues to rub against the grinding discs, thereby completing the grinding of its end face.
[0017] S04: Finally, after grinding, the uncut PE pipe usually pushes the cut PE pipe away from the conveying component, and at the same time, with the rotation of the push roller, the PE pipe is quickly unloaded.
[0018] The present invention has the following beneficial effects: 1. The present invention, by regulating the alternating operation of the incomplete gear ring and the second electromagnet, causes the sleeve to drive the PE pipe to reciprocate. At the same time, when the second arc-shaped clamping plate clamps the PE pipe, the two grinding discs move to a position that is concentrically attached to both ends of the PE pipe. During the reciprocating rotation of the PE pipe, its two ends continuously generate friction with the corresponding grinding discs, thereby completing the end grinding operation, improving the flatness of the cut end face and the cutting quality. In addition, the two sides of the PE pipe at the cut point are fixed before the cutting operation to prevent it from shifting in the radial direction, which would affect the flatness of the cross-section.
[0019] 2. This invention controls the first spur gear to mesh and drive the first incomplete gear to rotate. The first incomplete gear drives the conveyor roller to rotate through the first rotating shaft, which in turn drives the conveyor belt to rotate, thus realizing the conveying of PE pipes. When the first spur gear disengages from the first incomplete gear, the first incomplete gear stops rotating, the conveyor belt stops, and the PE pipe stops being conveyed. By intermittently conveying PE pipes, intermittent quantitative conveying can be achieved, preparing for subsequent cutting and grinding processes. At the same time, when the turntable rotates, it drives the connecting column to rotate. The connecting column abuts against the inner wall of the rectangular frame, causing the rectangular frame to move back and forth up and down, providing power for its reciprocating movement in the vertical direction.
[0020] 3. This invention controls a second motor to drive a worm gear to rotate, which in turn drives a second incomplete gear to rotate. When the second incomplete gear meshes with an incomplete gear ring, it drives the incomplete gear ring to rotate, providing external force. When the second incomplete gear rotates to the point where it no longer meshes with the incomplete gear ring and the incomplete gear ring resets, the second electromagnet is energized. The worm gear rotates and meshes, driving the worm wheel to rotate. This drives the first sprocket to rotate via the first rotating rod. The first sprocket drives the second sprocket to rotate via a chain, which in turn drives the second rotating rod and the push roller to rotate. This causes the push roller to move the polished PE pipe away from the polishing assembly, completing rapid unloading. This ensures the smooth coordination of the conveying, cutting, polishing, and unloading processes, improving the working efficiency of the device and the quality of the cut PE pipe.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Example 1, please refer to Figure 1-12 The present invention provides the following technical solution: a quantitative cutting device for PE pipe production, comprising a conveying component 1, a lifting component 2 disposed on the conveying component 1, a cutting component 3 disposed on one side of the conveying component 1, a grinding component 4 disposed on one side of the cutting component 3 disposed on the conveying component 1, a power component 5 disposed inside the grinding component 4, and a feeding component 6 disposed on the conveying component 1; the conveying component 1 is used for intermittent quantitative conveying of PE pipes; the lifting component 2 provides power for the operation of the conveying component 1 and simultaneously provides power for the vertical movement of the cutting component 3; the cutting component 3 is used for stable cutting of PE pipes; the grinding component 4 is used for simultaneously grinding both ends of the cut PE pipes; the power component 5 provides power for the operation of the grinding component 4; and the feeding component 6 is used for rapid feeding of the ground PE pipes.
[0026] Conveying assembly 1 includes a base 101, a mounting plate 102 fixedly connected to the top of the base 101, two sets of support plates 103 symmetrically fixedly connected to the top of the mounting plate 102, a crossbeam plate 104 fixedly connected between the two support plates 103, a plurality of first rotating shafts 105 rotatably connected between the two crossbeam plates 104, conveying rollers 106 fixedly connected to the outer wall of the first rotating shafts 105, and a conveyor belt 107 drivingly connecting the plurality of conveying rollers 106. A first incomplete gear 108 is fixedly connected to the end of one of the first rotating shafts 105. A loading platform 109 is fixedly connected to the top of the mounting plate 102, a guide tube 110 is fixedly embedded in the top of the loading platform 109, and a control box 111 is fixedly connected to the top of the base 101. Lifting assembly 2 includes a first motor 201 fixedly connected to the top of the mounting plate 102, a second rotating shaft 202 fixedly connected to the output end of the first motor 201, a first spur gear 203 that meshes with the first incomplete gear 108 fixedly connected to the outer wall of the second rotating shaft 202, a turntable 204 fixedly connected to the end of the second rotating shaft 202, and a connecting column 205 fixedly connected to one side of the turntable 204 off-center; the lifting assembly 2 also includes a guide rod 206 fixedly connected to the top of the mounting plate 102, a first baffle 207 fixedly connected to the top of the guide rod 206, an ear plate 208 slidably connected to the outer wall of the guide rod 206, and a rectangular frame 209 slidably sleeved on the outer wall of the connecting column 205 fixedly connected to one side of the ear plate 208.
[0027] The operation process of this embodiment is as follows: First, the PE pipe is smoothly passed through the guide tube 110 from the loading platform 109, so that it extends forward accurately to the surface of the conveyor belt 107. Then, the first motor 201 is started, and the output shaft of the first motor 201 starts to rotate, driving the second rotating shaft 202 connected to it to rotate synchronously. The rotation of the second rotating shaft 202 further drives the first spur gear 203 and the turntable 204 to rotate together. During the rotation, the first spur gear 203 meshes with the first incomplete gear 108, thereby driving the first incomplete gear 108 to start rotating. The first incomplete gear 108 transmits power to the conveyor roller 106 through the first rotating shaft 105, so that the conveyor roller 106 rotates accordingly, thereby driving the entire conveyor belt 107 to operate, realizing the continuous conveying of the PE pipe. When the first spur gear 203 rotates to a certain angle, it disengages from the first incomplete gear 108. At this time, the first incomplete gear 108 loses its driving force and stops rotating. The conveying roller 106 and the conveyor belt 107 also stop running, thereby temporarily interrupting the conveying process of the PE pipe. Through this intermittent conveying mechanism, quantitative and intermittent conveying of the PE pipe can be achieved, providing precise control for subsequent cutting and grinding processes, and ensuring the consistency and efficiency of the processing. Meanwhile, as the turntable 204 rotates, it drives the connecting column 205 fixed on it to rotate as well. During the movement, the connecting column 205 periodically contacts and pushes the inner wall of the rectangular frame 209, thereby driving the rectangular frame 209 to move up and down reciprocally in the vertical direction. This reciprocating motion provides a continuous and reliable power source for the rectangular frame 209, enabling it to rise and fall according to a set pattern to meet the needs of subsequent process steps.
[0028] Example 2, please refer to Figure 1-12 This second embodiment is an improvement on the first embodiment as follows: the cutting component 3 includes a mounting base 301 fixedly connected to the top of the base 101, a square rod 302 fixedly connected to the top of the mounting base 301, a second baffle 303 fixedly connected to the top of the square rod 302, an irregular plate 304 slidably connected to the outer wall of the square rod 302, a horizontal plate 305 fixedly connected to one end of the irregular plate 304, a laser cutter 306 fixedly connected to the bottom of the horizontal plate 305, a sliding rod 307 symmetrically slidably connected to the top of the horizontal plate 305, a limit plate 308 fixedly connected to the top of the sliding rod 307, a pad 309 fixedly connected to the bottom of the sliding rod 307, an arc plate 310 fixedly connected to the bottom of the pad 309, extension blocks 311 fixedly connected to both ends of the arc plate 310, a buffer pad 312 fixedly connected to the bottom of the extension blocks 311, and a first spring 313 sleeved on the sliding rod 307 fixedly connected between the horizontal plate 305 and the pad 309.
[0029] The operation process of this embodiment is as follows: When the PE pipe conveying process completely stops, the rectangular frame 209 accurately drives the irregular plate 304 to move downward, and then the horizontal plate 305 synchronously pushes the laser cutting machine 306 and the two side arc plates 310 to move downward along the preset trajectory. At this time, the PE pipe to be cut is exactly below the cutting component 3. The two arc plates 310 first contact and stably press against the outer wall surface of the PE pipe to achieve reliable clamping and fixing of both sides of the cutting area. Subsequently, the control system continues to drive the laser cutting machine 306 to feed downward, thereby quickly and accurately completing the cutting operation of the PE pipe. Through the coordinated action of the slide bar 307 and the first spring 313, the two arc plates 310 can always maintain a tight fit with the outer wall of the PE pipe during the continuous downward movement of the laser cutting machine 306. This design not only ensures the smooth and stable downward movement of the laser cutting machine 306, but also ensures the structural stability of the PE pipe throughout the cutting process. It effectively prevents the PE pipe from shifting or vibrating in the radial direction during cutting, thereby avoiding quality problems such as uneven cross-section and skewed cut caused by displacement. Ultimately, this mechanism significantly improves the flatness of the PE pipe cut cross-section and the overall processing quality. After the cutting operation is completed, driven by the rebound of the rectangular frame 209, the two arc plates 310 and the laser cutting machine 306 automatically return to their initial positions. Then, the conveying component 1 restarts and continues to convey the next section of PE pipe to be cut to the processing area in an intermittent and quantitative manner, preparing for subsequent cyclic cutting.

The connecting plate 411 has two curved sliders 412 fixedly connected to its opposite sides. A second curved clamping plate 413 is slidably sleeved between the two curved sliders 412. A slot 414 is opened through the outer wall of the second curved clamping plate 413. Curved grooves 415 that slide with the two sliders are opened on the two inner sides of the slot 414. A U-shaped seat 416 that slides with the moving rod 410 is fixedly connected to the outer wall of the sleeve 402. A second spring 417 that is sleeved on the outer wall of the moving rod 410 is fixedly connected between the U-shaped seat 416 and the sleeve 402. An iron plate 418 is fixedly connected to the top of the moving rod 410. A first electromagnet 419 that slides with the moving rod 410 is fixedly connected to the top of the U-shaped seat 416. A second electromagnet that attracts the corresponding curved slider 412 is fixedly embedded at the center of the inner wall of the two curved grooves 415.
[0031] An extension plate 420 is fixedly connected to one side of the iron plate 418, and a toothed plate 421 is fixedly connected to the bottom of the extension plate 420. The grinding assembly 4 also includes a first vertical plate 422 fixedly connected to the top of the cavity seat 401. A lead screw 423 is rotatably connected through one side of the first vertical plate 422. A moving plate 424 is threadedly connected to the outer wall of the lead screw 423. A second spur gear 425 that meshes with the toothed plate 421 is fixedly connected to the end of the lead screw 423. A load-bearing plate 426 is symmetrically fixedly connected to one side of the moving plate 424. A grinding disc 427 is fixedly connected to one side of the load-bearing plate 426. An L-shaped rod 428 that slides with the cavity seat 401 is fixedly connected to the adjacent side of the load-bearing plate 426. Guide grooves 429 that slide with the two L-shaped rods 428 are symmetrically opened on the top of the cavity seat 401.
[0032] The operation process of this embodiment is as follows: The PE pipe to be cut is continuously fed to the cutting assembly 3, causing the PE pipe to be cut to push the already cut PE pipe towards the grinding assembly 4, so that the cut PE pipe moves into the sleeve 407. At this time, the outer wall of the PE pipe contacts the first arc-shaped clamping plate 409 below. Subsequently, the first electromagnet 419 is energized, so that it generates magnetic force, attracting the iron plate 418 to move downward, and then the moving rod 410 drives the second arc-shaped clamping plate 413 to move downward, so that the second arc-shaped clamping plate 413 tightly fits against the outer wall of the PE pipe, completing the locking of the PE pipe. During the downward movement of the iron plate 418, the iron plate 418 drives the toothed plate 421 to move downward through the extension plate 420, so that the toothed plate 421 meshes with the second spur gear 425, driving the second spur gear 425 to rotate, which in turn drives the lead screw 423 to rotate, so that the lead screw 423 drives the moving plate 424 to move closer to the PE pipe. The moving plate 424 drives the two grinding discs 427 to move towards the PE pipe through the two load-bearing plates 426. When the second arc-shaped clamping plate 413 just completes the clamping of the PE pipe, the two grinding discs 427 just move to the position where they are concentrically attached to both ends of the PE pipe. Subsequently, the incomplete gear ring 403 is controlled to rotate along the arc-shaped limiting groove 404, driving the sleeve 407 and PE pipe to rotate synchronously via the annular plate 406. During this process, the second electromagnet is de-energized, and the second arc-shaped clamping plate 413 can rotate together with the sleeve 407. After the incomplete gear ring 403 is no longer under force, the second electromagnet is energized to generate magnetic force, attracting the arc-shaped slider 412. Since the arc-shaped slider 412 is in a fixed state, the second electromagnet drives the second arc-shaped clamping plate 413 to reset, further driving the sleeve 407 and PE pipe to reset, thus realizing the reset of the PE pipe. During the reciprocating rotation of the PE pipe, both ends of the PE pipe continuously rub against the corresponding grinding disc 427, completing the grinding of its ends, improving the flatness of the cut end face of the PE pipe, and thus improving the cutting quality. After the grinding is completed, the first electromagnet 419 is de-energized. Under the elastic force of the second spring 417, the iron plate 418 moves upward, causing the second arc-shaped clamping plate 413 to reset. At the same time, the iron plate 418 drives the toothed plate 421 to move upward through the extension plate 420, driving the second spur gear 425 and the lead screw 423 to rotate in the opposite direction, thereby resetting the two grinding discs 427.
[0033] Example 4, please refer to Figure 1-12This fourth embodiment is an improvement on the first embodiment as follows: the power assembly 5 includes a pad 501 fixedly connected to the bottom of the cavity seat 401, a second motor 502 fixedly connected to the top of the pad 501, a worm gear 503 fixedly connected to the output end of the second motor 502, a first fixing plate 504 fixedly connected to the bottom of the cavity seat 401 rotatably connected to the outer wall of the worm gear 503, and a second incomplete gear 505 meshing with the incomplete gear ring 403 fixedly connected to the end of the worm gear 503. The power assembly 5 also includes a second vertical plate 506 fixedly connected to the bottom of the cavity seat 401, a first rotating rod 507 rotatably connected through one side of the second vertical plate 506, a worm wheel 508 meshing with the worm gear 503 fixedly connected to one end of the first rotating rod 507, and a first sprocket 509 fixedly connected to the other end of the first rotating rod 507.
[0034] The feeding assembly 6 includes a second fixing plate 601 fixedly connected to the top of the base 101. A second rotating rod 602 is rotatably connected to one side of the second fixing plate 601. A push roller 603 is fixedly connected to the outer wall of the second rotating rod 602. A rubber sleeve is fixedly fitted on the outer wall of the push roller 603. A second sprocket 604 is fixedly connected to the end of the second rotating rod 602. A chain meshes and drives the second sprocket 604 and the first sprocket 509.
[0035] The operation process of this embodiment is as follows: by controlling the operation of the second motor 502, the worm gear 503 is driven to rotate. The worm gear 503 further transmits power to the second incomplete gear 505, causing it to rotate. During this process, the second incomplete gear 505 meshes with the incomplete gear ring 403, thereby driving the incomplete gear ring 403 to rotate and providing it with the necessary external driving force. When the second incomplete gear 505 rotates to the position where it disengages from the incomplete gear ring 403, the incomplete gear ring 403 needs to perform a reset action. At this time, the second electromagnet needs to be energized to perform the corresponding operation. The specific operation process has been described in detail in the previous embodiment. Meanwhile, the rotation of the worm 503 further meshes and drives the worm wheel 508 to rotate. The worm wheel 508 drives the first sprocket 509 to rotate through the first rotating rod 507. The first sprocket 509 transmits power to the second sprocket 604 through chain transmission, which in turn drives the second rotating rod 602 and the push roller 603 to rotate together. During the rotation, the push roller 603 pushes the PE pipe that has been polished to move smoothly in the direction away from the polishing component 4, so as to achieve fast and automatic feeding. The entire process achieves orderly connection and efficient coordination of each link from conveying, cutting, grinding to unloading, which not only significantly improves the working efficiency of the equipment, but also helps to ensure the processing quality and overall process level of the PE pipe fittings after cutting.
