Description

Technical Field

[0001] This invention relates to the field of pipe cutting technology, specifically to an anti-collapse edge cutting device for recycled material drainage pipes. Background Technology

[0002] In order to control costs, polyethylene solid wall drainage pipes are generally made with recycled materials in different proportions during production. These recycled materials have complex sources, unstable melt flow index, and may contain impurities or be subject to aging and degradation. This results in uneven stress distribution, poor material continuity, and large fluctuations in local mechanical properties within the pipe itself. Therefore, during the cutting process of recycled material drainage pipes, the pipe wall is prone to splitting and delamination along the fiber direction or between layers at the break point. It is also easy to form burrs, chipping, or irregular nicks at the cut edge, resulting in poor cut quality and affecting appearance and performance.

[0003] Application document CN121403487A discloses a plastic pipe cutting device with a pipe anti-deviation structure, including a cutting base frame and a movable frame. Movable frames are rotatably arranged on both sides of the top of the cutting base frame. Conveying and positioning units are arranged inside the two movable frames and on both sides inside the cutting base frame. An installation frame is also fixedly arranged inside the cutting base frame and between the two movable frames, and a planetary cutting unit is arranged inside the installation frame.

[0004] According to the aforementioned patents and existing technologies, existing technologies employ two or more consecutive cuts to avoid edge chipping when cutting pipes. This can easily lead to stepped end faces due to difficulty in aligning the cut lines between the two cuts, requiring more time for reprocessing and significantly reducing overall work efficiency and extending the overall project duration. Furthermore, existing technologies often require fixed supports to restrict the movement of the cutting blade when preventing edge chipping, resulting in a smaller range of pipe sizes that can be processed. This necessitates the production of multiple machines to handle a wide variety of drainage pipe sizes, causing significant waste. Additionally, existing technologies struggle to prevent edge chipping when cutting thick-walled drainage pipes, making it difficult to avoid edge chipping during the cutting process of thick-walled recycled material drainage pipes. Summary of the Invention

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Please see Figure 1-10 As shown: A chipping-resistant cutting device for recycled material drainage pipes includes a support groove ring 101. A first transmission ring 102 is rotatably mounted on the front side of the support groove ring 101, and a positioning support ring 201 is fixedly mounted on the rear side of the support groove ring 101. Several pairs of first support seats 103 are symmetrically arranged on the front ring surface of the first transmission ring 102. Each first support seat 103 is hinged with an arc-shaped swing rod 112, and a second support seat 113 is installed at the end of each arc-shaped swing rod 112. The upper rotating part is provided with a cutting machine bracket 114, and a cutting machine is installed inside the cutting machine bracket 114. Two fixed support shafts 203 are symmetrically provided on the upper and lower sides of the side of the positioning support ring 201. Each pair of fixed support shafts 203 is provided with a positioning wheel frame 202 on both sides. A first side support rod 204 is hinged between one side of the positioning wheel frame 202 and the corresponding fixed support shaft 203. A second side support rod 205 is hinged to the other side of the positioning wheel frame 202. A support block 206 is correspondingly hinged to the second side support rod 205. In this embodiment, the overall stability is maintained by the support groove ring 101. By synchronously driving each support block 206 to push the corresponding second side support rod 205, each positioning wheel frame 202 extends out of the outer periphery of the support groove ring 101. The overall support stability is maintained by the support of the positioning wheel frame 202 on the ground or the inner wall of the recycled material drainage pipe. The stable support of the positioning wheel frame 202 makes the support groove ring 101 and the cross section of the recycled material drainage pipe coplanar, so that the cutting wheel of the cutting machine always maintains a vertical state to cut the recycled material drainage pipe. Different approaches are taken for different diameters of recycled material drainage pipes. When the diameter of the recycled material drainage pipe is smaller than the inner diameter of the support groove ring 101, the recycled material drainage pipe is inserted coaxially into the hollow of the support groove ring 101. Then, each arc-shaped swing arm 112 rotates inward synchronously, so that the cutting machine on each cutting machine bracket 114 comes into contact with the recycled material drainage pipe. Then, the arc-shaped swing arm 112 and the cutting machine are rotated uniformly and stably through the first transmission ring 102. The cutting wheel speed of the cutting machine and the speed of the first transmission ring 102 are adjusted in a targeted manner according to the different contents and types of recycled material drainage pipes. In this way, various types and diameters of recycled material drainage pipes are cut in one go without edge breakage. The device and the recycled material drainage pipe are moved relative to each other by moving the recycled material drainage pipe or by using the self-driven positioning wheel frame 202, so as to cut the pipe simply, efficiently and precisely. When the inner diameter of the recycled material drainage pipe is larger than the outer diameter of the support groove ring 101, the device is driven by the self-driven positioning wheel frame 202 to move stably and a fixed distance inside the recycled material drainage pipe. The cutting machine of the cutting machine bracket 114 is set to face outward, and each arc-shaped swing arm 112 rotates outward synchronously, so that the cutting machine on each cutting machine bracket 114 comes into contact with the recycled material drainage pipe. This allows for the one-time anti-collapse edge cutting of various types and diameters of recycled material drainage pipes from the inside out, achieving rapid switching of work effects.

[0022] The center of the circle containing the arc-shaped rocker arm 112 is concentric with the support groove ring 101. A first mounting box 104 is installed on the inner bottom of the first support base 103. A first motor 105 is installed on the inner bottom of the first mounting box 104. A first rotating shaft 106 is rotatably connected to the inner top of the first mounting box 104. A first worm gear 109 is fixedly sleeved in the middle of the first rotating shaft 106. A support rotation frame 110 is rotatably connected to the inner top of the first support base 103. One side of the support rotation frame 110 is connected to the end of the arc-shaped rocker arm 112. The first worm gear ring 111 is fixedly connected to the rotating support frame 110 and fixedly installed on the other sides. The first worm gear ring 111 meshes with the first worm 109 for transmission. The first rotating shaft 106 is parallel to the drive shaft of the first motor 105. The two ends of the first rotating shaft 106 and the two ends of the drive shaft of the first motor 105 are fixedly sleeved with first sprockets 107. The two first sprockets 107 on each side are respectively sleeved with the first chain 108, and the two first sprockets 107 on each side are respectively transmitted through the first chain 108. During operation, the arc of the arc-shaped swing arm 112 is concentric with the support groove ring 101, preventing the swing of the arc-shaped swing arm 112 from interfering with the inlet and movement of the recycled material drainage pipe. Driven by the first motor 105 and transmitted by the first sprocket 107 and the first chain 108, the first rotating shaft 106 rotates the first worm gear 109, driving the first worm wheel ring 111 and the support rotating frame 110 to rotate. This allows the arc-shaped swing arm 112 and the cutting machine on the cutting machine bracket 114 to swing accurately. The self-locking property of the worm gear transmission structure keeps the arc-shaped swing arm 112 stably supported, allowing the cutting machine on the cutting machine bracket 114 to cut stably and reducing the impact of vibration on edge chipping.

[0023] A second mounting box 116 is installed on the inner bottom of the second support base 113. A second worm gear ring 115 is fixedly connected to the outer peripheral side wall of the cutting machine bracket 114. A second rotating shaft 118 is rotatably connected to the inner top of the second mounting box 116. A second worm 121 is fixedly sleeved on the second rotating shaft 118. The second worm 121 meshes with the second worm gear ring 115 for transmission. A second motor 117 is installed on the inner bottom of the second mounting box 116. A second sprocket 119 is fixedly sleeved on both ends of the second rotating shaft 118 and both ends of the drive shaft of the second motor 117. The two second sprockets 119 on each side mesh with the second chain 120 for transmission. During operation, driven by the second motor 117 and transmitted through the second sprocket 119 and the second chain 120, the second rotating shaft 118 rotates the second worm gear 121, driving the second worm ring 115 and the cutting machine bracket 114 to rotate. This allows the cutting machine on the cutting machine bracket 114 to rotate accurately, so that the midpoint of the arc of the exposed cutting wheel on the cutting machine abuts against the side wall of the pipe being cut. This ensures that the cutting wheel of the cutting machine always maintains the maximum cutting depth, thus adapting to recycled material drainage pipes of different thicknesses.

[0024] A rotating transmission ring 122 is inserted through the middle of one side of the support groove ring 101 near the first transmission ring 102. The support groove ring 101 and the rotating transmission ring 122 are rotatably connected. One side of the rotating transmission ring 122 is fixedly connected to the first transmission ring 102, and the other side of the rotating transmission ring 122 is fixedly connected to the second transmission ring 123. A third motor 124 is installed at the bottom inner side of the support groove ring 101. A transmission gear 125 is rotatably connected to the top inner side of the support groove ring 101 and located on the inner and outer circumferences of the second transmission ring 123. The transmission gear 125 meshes with the second transmission ring 123 for transmission. Transmission bevel gears 126 are fixedly sleeved on the side surface of the transmission gear 125 and both ends of the drive shaft of the third motor 124. The two transmission bevel gears 126 on each side mesh with each other for transmission. During operation, when the cutting wheels of each cutting machine cut through the side wall of the recycled material drainage pipe, the third motor 124 starts and, through the transmission bevel gear 126 and transmission gear 125, causes the second transmission ring 123 to rotate at a constant speed. The rotating transmission ring 122 drives the first transmission ring 102, thereby moving each cutting machine synchronously and cutting the pipe quickly and efficiently.

[0025] The positioning support ring 201 is fitted with two outer groove plates 207 and two inner groove plates 209. The two outer groove plates 207 and two inner groove plates 209 are centrally symmetrically arranged and staggered. An outer limiting groove 208 is formed through the center of the outer groove plate 207, and an inner limiting groove 210 is formed through the center of the inner groove plate 209. The positioning support ring 201 has an annular cavity containing an outer drive ring 211 and an inner drive ring 212. Both the outer drive ring 211 and the inner drive ring 212 are maintained in a stable rotational state within the positioning support ring 201 by limiting gears 213 arranged in a uniform annular array. The outer drive ring 211, the inner drive ring 212, the support groove ring 101, and the positioning support... The ring 201 is coaxial, and the inner transmission ring 212 is located inside the outer transmission ring 211. The outer transmission ring 211 is fixedly connected to the corresponding support block 206 through the outer transmission block 214. The inner transmission ring 212 is fixedly connected to the corresponding support block 206 through the inner transmission block 215. The outer transmission block 214 and the outer limiting groove 208 are slidably connected. The inner transmission block 215 and the inner limiting groove 210 are slidably connected. A fourth motor 216 is provided in the annular cavity of the positioning support ring 201 and between the outer transmission ring 211 and the inner transmission ring 212. The fourth motor 216 drives the outer transmission ring 211 and the inner transmission ring 212 in opposite directions through the active gear 217. A counterweight block 218 is provided on the bottom side of the positioning support ring 201. During operation, the second side support rod 205 and the first side support rod 204 jointly push the positioning wheel frame 202 to extend synchronously. When the recycled material drain pipe passes through the center of the support groove ring 101, it is supported and translated by the two positioning wheel frames 202 at the bottom. When the device moves inside the recycled material drain pipe, the synchronously extended positioning wheel frames 202 make the support groove ring 101 and the recycled material drain pipe concentric. Through the translation of the positioning wheel frames 202, pipes of different diameters are stably, efficiently, and in batches are cut into several parts. The fourth motor 216 rotates the drive gear 217, which synchronously rotates the outer transmission ring 211 and the inner transmission ring 212 in opposite directions. In this embodiment, the outer transmission ring 211 is connected to the upper left and lower right support blocks 206 respectively through the outer transmission block 214, and the inner transmission ring 212 is connected to the support blocks 206 respectively through the outer transmission block 214. The inner transmission block 215 is connected to the lower left and upper right support blocks 206 respectively. Under the synchronous reverse rotation of the outer transmission ring 211 and the inner transmission ring 212, and with the outer transmission ring 211 rotating clockwise and the inner transmission ring 212 rotating counterclockwise, the second side support rods 205 on both sides synchronously and symmetrically converge towards the center. This causes each positioning wheel frame 202 to extend synchronously to the upper and lower sides under the limit of the first side support rod 204. When the outer transmission ring 211 rotates counterclockwise and the inner transmission ring 212 rotates clockwise, each positioning wheel frame 202 retracts to the side of the positioning support ring 201, thereby compressing the overall volume and facilitating the transportation of the structure itself. The counterweight block 218 lowers the center of gravity of the structure itself and reduces the impact of vibration during pipe cutting on the cutting surface, thereby improving the cutting effect.

[0026] In summary, by rotating the arc-shaped swing arms 112 synchronously, the cutting machines on each cutting machine bracket 114 come into contact with the recycled material drainage pipes. Then, the first transmission ring 102 rotates the arc-shaped swing arms 112 and the cutting machines at a uniform and stable speed, thereby quickly and efficiently cutting various types and diameters of recycled material drainage pipes in one go. The cutting wheel speed of the cutting machine and the speed of the first transmission ring 102 are adjusted specifically for drainage pipes with different recycled material content and types to prevent edge chipping. When the diameter of the recycled material drainage pipe is smaller than the inner diameter of the support groove ring 101, the recycled material drainage pipe is inserted into the hollow part of the support groove ring 101 in a coaxial manner. Then, each arc-shaped swing arm 112 rotates inward synchronously, so that the cutting machine on each cutting machine bracket 114 abuts against the recycled material drainage pipe. Then, the arc-shaped swing arm 112 and the cutting machine are rotated at a uniform speed and stably through the first transmission ring 102, so as to quickly cut various types and small diameter recycled material drainage pipes with anti-chipping edge cutting. When the inner diameter of the recycled material drainage pipe is larger than the outer diameter of the support groove ring 101, the device is driven by the self-driven positioning wheel frame 202 to move stably and a fixed distance inside the recycled material drainage pipe. The cutting machine of the cutting machine bracket 114 is set outward, and each arc-shaped swing arm 112 rotates outward synchronously, so that the cutting machine on each cutting machine bracket 114 comes into contact with the recycled material drainage pipe. This allows for the one-time cutting of recycled material drainage pipes of various types and diameters from the inside out to prevent edge breakage, achieving rapid switching of work effects. This further increases the range of recycled material drainage pipe diameters that can be cut, reduces the user's equipment purchase costs, and saves the storage and maintenance costs incurred in dealing with multiple backup equipment and accessories. The cutting and maintenance processes are simplified, improving the workers' proficiency in operating the equipment. On-site scheduling is more flexible and efficient, promoting the ability to operate continuously, improving equipment utilization, and avoiding idleness. By specifically adjusting the rotation speed and feed speed of the cutting wheel, as well as the material of the cutting wheel, the chipping of various recycled material drainage pipes can be reduced or avoided during cutting. This eliminates the need for repeated cutting, improves overall work efficiency, avoids defects such as steps or cracks on the cut surface, and increases the yield of the cutting results.

[0027] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
