Description

Technical Field

[0001] This invention relates to the field of material feeding vibration reduction technology, and in particular to a vibration reduction mechanism and a pipe buffer feeding device using the same. Background Technology

[0002] In the production process of PVC and MPP pipes, the overall process includes raw material mixing, fusion, extrusion, vacuuming, cooling and shaping, traction, and cutting. After cutting, the pipe is formed and needs to be transported and stored for unified packaging in subsequent processes.

[0003] On the overall production line, after the pipes are cut, they are pushed up by the uncut pipes and continue to move along the conveyor frame. Because pipe production requires steps such as extrusion and cooling, there is a significant height difference between the conveyor frame at the end of the production line and the ground. Traditionally, companies mainly use manual labor to handle the cut pipes. Since the pipes used in projects are long and heavy, this is time-consuming, labor-intensive, and prone to safety issues. Furthermore, if a straight unloading structure is installed at the end of the production line, it will occupy too much space, severely affecting the installation and setup of other equipment in the workshop. If ramps or other structures are used for lateral pipe transport, the pipes tend to roll at high speeds, making it difficult to control the rolling direction and increasing the risk of collisions at the end, damaging the pipes or other equipment in the workshop. While vertical drop methods maximize space utilization, the pipes are prone to damage upon impact. Even with cushioning and vibration damping structures to support the pipes, their overall length and potential tilting to one side during the fall make it difficult for conventional cushioning and vibration damping structures to effectively absorb the overall load. This can lead to excessive localized stress, causing the cushioning and vibration damping structures to fail or be damaged.

[0004] Therefore, how to buffer and reduce vibration of cut pipes in a limited space to avoid damage caused by pipes falling or to prevent safety issues has become a research direction. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: a vibration damping mechanism and a pipe buffer feeding device using the same, which solves the problem of pipe damage or easy failure of the buffer and vibration damping structure during the pipe feeding process in the existing pipe production line.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a vibration damping mechanism, comprising:

[0007] The central buffer assembly includes a flexible shell, buffer particles, and a central support member. The buffer particles are filled inside the flexible shell, and the central support member is spaced out inside the flexible shell. When the central support member is compressed, it pushes the buffer particles outwards. The flexible shell is distributed along a first direction, and the height of the flexible shell gradually decreases along a second direction.

[0008] The edge vibration damping components are set on both sides of the length direction of the middle buffer components, including a fixed base, a support plate, a connecting column and a buffer spring. The fixed base has a sliding cavity. One end of the connecting column is set in the sliding cavity and slides up and down along the sliding cavity. The other end of the connecting column is connected to the support plate. The buffer spring is sleeved on the connecting column and located between the fixed base and the support plate.

[0009] A buffer balancing assembly is disposed between the edge damping assembly and the middle buffer assembly. One end of the buffer balancing assembly is slidably connected to the connecting column. The lifting and lowering of the connecting column causes the buffer balancing assembly to move along the first direction. The other end of the buffer balancing assembly abuts against the side wall of the flexible shell.

[0010] In one embodiment, the buffer balancing assembly includes a lifting cone, an abutting link, a push plate, and a return spring. The lifting cone is located at the end of the connecting column away from the receiving plate and within the sliding cavity. One end of the abutting link extends from the outside of the fixed base into the sliding cavity and abuts against the conical surface of the lifting cone. The other end of the abutting link is connected to the push plate. The return spring is arranged around the abutting link and between the push plate and the fixed base.

[0011] In one embodiment, the buffer balancing assembly further includes a sliding track that extends from the bottom of the fixed base toward the flexible housing. The push plate has a sliding notch corresponding to the sliding track, and the push plate moves back and forth along the sliding track.

[0012] In one embodiment, the central support member includes a support base, a support shaft, a support spring, a limiting rod, a pushing ring, a pushing rod, and a pushing arc plate. The support base is disposed at the bottom of the flexible shell, and a sliding cavity is provided inside the support base. One end of the support shaft abuts against the top of the flexible shell, and the other end of the support shaft extends into the sliding cavity and slides along the sliding cavity. The support spring is disposed in the sliding cavity, and both ends of the support spring abut against the support shaft and the bottom of the sliding cavity, respectively. The limiting rod is disposed at the center of the sliding cavity and extends from the bottom of the sliding cavity toward the support shaft. The support shaft has a groove corresponding to the limiting rod, and the limiting rod extends into the groove. The pushing ring is connected to the bottom of the support shaft and sleeved on the limiting rod. The pushing arc plate is disposed around the support base, and the top of the pushing arc plate is hinged to the top of the support base. One end of the pushing rod is hinged to the pushing ring, and the other end of the pushing rod passes through the opening of the support base and is hinged to the bottom of the pushing arc plate.

[0013] The present invention also provides a pipe buffer feeding device for conveying pipes, comprising:

[0014] The conveying body is distributed along the first direction and has a conveying platform on top;

[0015] The flipping module includes a flipping arc plate, a telescopic push rod, and a triggering component. One side of the flipping arc plate is rotatably connected to the conveying body, and the other side of the flipping arc plate abuts against the conveying table surface. The two ends of the telescopic push rod are respectively hinged to the middle of the conveying body and the flipping arc plate. The triggering component is located at the end of the conveying table surface. After the pipe moves along the flipping arc plate to the triggering component, the triggering component triggers the telescopic push rod to move.

[0016] The receiving module is set and located on the side where the conveying body and the flipping module are hinged. The receiving module has a receiving channel, and the receiving channel is equipped with any of the vibration damping mechanisms described above. The side wall of the receiving channel is provided with a material discharge opening corresponding to the vibration damping mechanism.

[0017] The control module is electrically connected to the flip module and the receiving module.

[0018] In one embodiment, the triggering assembly includes a triggering ramp, a triggering spring, and a triggering element. One end of the triggering ramp is hinged to the conveyor table surface along its length. Both ends of the triggering element are respectively hinged to the triggering ramp and the conveyor table surface. The triggering spring is sleeved on the triggering element and disposed between the triggering ramp and the conveyor table surface.

[0019] The height of the side of the trigger ramp closest to the flipping arc plate is lower than the height of the flipping arc plate, while the trigger spring and trigger components make the height of the side of the trigger ramp furthest from the flipping arc plate higher than the height of the flipping arc plate.

[0020] In one embodiment, the trigger includes a fixed part and a telescopic part. The fixed part has a trigger cavity. One end of the telescopic part is hinged to the trigger inclined plate. The end of the telescopic part away from the trigger inclined plate is disposed in the trigger cavity and slides along the trigger cavity. A trigger button is provided at the bottom of the trigger cavity. After the trigger inclined plate is pressed and rotated, it drives the telescopic part to slide along the trigger cavity. After the telescopic part slides to the end of the trigger cavity, it abuts against the trigger button and triggers the trigger button.

[0021] In one embodiment, the receiving channel includes a wide opening section and a descending section. The descending section is located below the wide opening section, and the vibration damping mechanism is located inside the descending section. The discharge opening is provided with a discharge cover plate and a rotary motor. The fixed end of the rotary motor is located on the side wall of the descending section, and the output end of the rotary motor is driven connected to the top of the discharge cover plate. The top of the discharge cover plate is rotatably connected to the side wall of the discharge opening.

[0022] In one embodiment, a discharge platform is provided outside the discharge opening. The height of the discharge platform gradually decreases from the side closer to the discharge platform to the side farther away from the discharge platform. Guide arc plates are provided on both sides of the discharge platform in the first direction. The distance between the guide arc plates gradually decreases from the end closer to the discharge platform to the end farther away from the discharge platform.

[0023] In one embodiment, a distance sensor is provided at the bottom of the fixed base, which is used to detect the displacement distance of the connecting column.

[0024] The beneficial effects of this invention are as follows:

[0025] Conventional damping structures mainly use springs or air cushions to support the pipes. However, due to the heavy weight of the pipes used in the project, the overall potential energy was large under the acceleration of the fall, and there was a possibility of one side tilting and contacting first. This could easily exceed the damping limit of conventional damping structures, resulting in damage to the damping structure or the pipes.

[0026] This invention employs a flexible shell internally filled with buffer particles and side vibration damping components positioned on both sides of the flexible shell. The side vibration damping components first provide initial deceleration and support for the two ends of the falling pipe. During the descent of the side vibration damping components, the pipe experiences a certain degree of deceleration and buffering. Then, after the side vibration damping components have descended a certain distance, most of the pipe comes into contact with the flexible shell. The elastic deformation and friction of the flexible shell and the buffer particles absorb the potential energy generated by the pipe's descent, thus achieving smooth pipe feeding.

[0027] Meanwhile, relying solely on the central buffer assembly, the flexible shell and buffer particles are prone to denting after the pipe descends and impacts, causing the pipe to sink into the central buffer assembly. Therefore, this invention employs a buffer balancing assembly to coordinate the edge vibration damping assembly and the central buffer assembly. After the edge vibration damping assembly is compressed and descends, the buffer balancing assembly pushes the flexible shell, causing it to move towards the center, thus slightly arching the top of the flexible shell to better support the pipe. When the pipe contacts the flexible shell, the impact force pushes the flexible shell to both sides. This force is transmitted through the buffer balancing assembly to the edge vibration damping assembly, lifting it and providing a certain lifting force to both ends of the pipe. This further buffers the pipe while preventing it from sinking into the central buffer assembly, thus achieving vibration damping and pipe support. Furthermore, the height of the flexible shell gradually decreases along the second direction, meaning that the contact surface between the flexible shell and the pipe is tilted to one side. Under equilibrium conditions, the pipe slowly rolls along the tilt direction of the flexible shell under the pushing force of the edge damping component, thereby enabling the pipe to automatically leave the damping mechanism and ensuring the continuity of subsequent production.

[0028] While the buffer balancing component can withstand pressure and push the flexible shell, making it likely to return to its original shape, over long-term use, the height of the two sides of the flexible shell will be higher than that of the middle, causing a certain degree of depression in the middle area. In order to ensure that the entire pipe can be buffered in a timely manner, this invention sets a central support member inside the flexible shell. After the central support member is set, it lifts the flexible shell, thereby forming a protrusion in the middle area. The central support member pre-supports the pipe inside the flexible shell, and after support, pushes the buffer particles inside the flexible shell, so that the entire pipe can be fully buffered and achieve a good vibration reduction effect.

[0029] The pipe buffer unloading device provided by this invention employs a vibration damping mechanism within the receiving module. Simultaneously, a flipping module is installed on the conveying body, and a flipping arc plate receives the pipe. After the pipe reaches the trigger component, a telescopic push rod flips the arc plate, causing the pipe to fall into the receiving module. After being buffered and damped by the vibration damping mechanism, the pipe exits through the unloading opening. The entire process is simple, convenient, and can be automated, significantly saving installation space.

[0030] Other features and beneficial effects of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects of the invention and other beneficial effects may be realized and obtained by means of the structures and / or components pointed out in the description and claims.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. The technical features designed in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. 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.

[0046] In the description of this invention, it should be noted that all terms used in this invention (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains, and should not be construed as limiting the invention; it should be further understood that the terms used in this invention should be understood to have the same meaning as those in the context of this specification and in the relevant field, and should not be understood in an idealized or overly formal sense, except as expressly defined in this invention.

[0047] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0048] Please refer to Figures 1 to 11 A vibration damping mechanism 1, comprising:

[0049] The central buffer assembly 11 includes a flexible shell 111, buffer particles 112, and a central support member 113. The buffer particles 112 are filled inside the flexible shell 111, and the central support member 113 is spaced out inside the flexible shell 111. When the central support member 113 is compressed, it pushes the buffer particles 112 outwards. The flexible shell 111 is distributed along a first direction, and the height of the flexible shell 111 gradually decreases along a second direction.

[0050] The edge damping assembly 12 is disposed on both sides of the middle buffer assembly 11 along its length direction. It includes a fixed base 121, a receiving plate 122, a connecting column 123, and a buffer spring 124. The fixed base 121 has a sliding cavity. One end of the connecting column 123 is disposed in the sliding cavity and slides up and down along the sliding cavity. The other end of the connecting column 123 is connected to the receiving plate 122. The buffer spring 124 is sleeved on the connecting column 123 and is located between the fixed base 121 and the receiving plate 122.

[0051] The buffer balancing component 13 is disposed between the side vibration damping component 12 and the middle buffer component 11. One end of the buffer balancing component 13 is slidably connected to the connecting column 123. The lifting and lowering of the connecting column 123 causes the buffer balancing component 13 to move along the first direction. The other end of the buffer balancing component 13 abuts against the side wall of the flexible shell 111.

[0052] Specifically, the tilt angle of the top of the flexible shell 111 ranges from 5° to 10°. Furthermore, the receiving plate 122 is also tilted, but its tilt angle is smaller than that of the flexible shell 111. Even further, the tilt angle of the receiving plate 122 ranges from 3° to 8°.

[0053] The flexible shell 111 completely binds the internal buffer particles 112. Under the action of gravity, the unconstrained buffer particles 112 drive the flexible shell 111 to diffuse and flow in all directions until the whole reaches a state of equilibrium. In order to make the shape of the flexible shell 111 conform to the expected shape when receiving the pipe, in this embodiment, the buffer balance component 13 includes a lifting cone 131, an abutting connecting rod 132, a pushing plate 133, and a return spring 134. The lifting cone 131 is located at the end of the connecting column 123 away from the receiving plate 122 and is located in the sliding cavity. One end of the abutting connecting rod 132 extends from the outside of the fixed base 121 into the sliding cavity and abuts against the conical surface of the lifting cone 131. The other end of the abutting connecting rod 132 is connected to the pushing plate 133. The return spring 134 is arranged around the abutting connecting rod 132 and is located between the pushing plate 133 and the fixed base 121. The push plate 133 is set on both sides of the flexible shell 111 along its length. Under the action of the push plate 133, the flexible shell 111 slightly shrinks towards the middle, and the height of both sides of the flexible shell 111 along its length increases slightly from the initial height, so as to make timely contact with the pipe. After contact, the impact force is absorbed by the flow of the buffer particles 112, and the force is transmitted to the receiving plate 122 through the push-and-block connecting rod 132 of the flexible shell 111, providing an upward force to both ends of the pipe to further offset the downward force, so that the pipe can quickly reach equilibrium.

[0054] Preferably, the flexible shell 111 has fixing plates on both sides in the width direction, which are used to fix and limit the deformation of the flexible shell 111.

[0055] After the lifting cone 131 descends, the abutting link 132 is pushed by the lifting cone 131 towards the flexible housing 111. During repeated use, it is necessary to ensure that the abutting link 132 does not dislodge from the sliding cavity, thereby avoiding problems with the resetting of the abutting link 132. Therefore, the diameter of the lifting cone 131 gradually decreases from the end near the connecting post 123 to the end away from the connecting post 123, and the maximum diameter of the lifting cone 131 is smaller than the diameter of the sliding cavity.

[0056] Preferably, in order to ensure that the connecting column 123 does not deviate after being subjected to the reaction force of the abutting connecting rod 132, the connecting column 123 above the lifting cone 131 has an extension portion, the diameter of which is the same as the diameter of the sliding cavity, so that the connecting column 123 does not tilt when it is along the sliding cavity, thus ensuring the stability of the overall transmission process.

[0057] In this embodiment, the central support member 113 includes a support base 1131, a support shaft 1132, a support spring 1133, a limiting rod 1134, a pushing ring 1135, a pushing rod 1136, and a pushing arc plate 1137. The support base 1131 is disposed at the bottom of the flexible shell 111, and a sliding cavity 1138 is provided inside the support base 1131. One end of the support shaft 1132 abuts against the top of the flexible shell 111, and the other end of the support shaft 1132 extends into the sliding cavity 1138 and slides along the sliding cavity 1138. The support spring 1133 is disposed in the sliding cavity 1138, and both ends of the support spring 1133 abut against the support shaft 1132 and the bottom of the sliding cavity 1138, respectively. The limiting rod 1134 is located at the center of the sliding cavity 1138 and extends from the bottom of the sliding cavity 1138 toward the support shaft 1132. The support shaft 1132 is provided with a groove 1139 corresponding to the limiting rod 1134, and the limiting rod 1134 extends into the groove 1139. The push ring is connected to the bottom of the support shaft 1132 and is sleeved on the limiting rod 1134. The push arc plate 1137 is arranged around the support base 1131. The top of the push arc plate 1137 is hinged to the top of the support base 1131. One end of the push rod 1136 is hinged to the push ring, and the other end of the push rod 1136 passes through the push opening 11311 of the support base 1131 and is hinged to the bottom of the push arc plate 1137. With this configuration, the support shaft 1132 abuts against the falling pipe. Under pressure, the support shaft 1132 slides along the sliding cavity 1138, causing the push ring to descend along the limiting rod 1134. The displacement of the push ring then causes the push rod 1136 to shift, prompting the push arc plate 1137 to rotate. This pushes the buffer particles 112 at the moment of receiving the pipe, causing them to move upwards and contact the pipe for cushioning. The pressure applied to the buffer particles 112 transmits some of the force to the support shaft 1132 via the push arc plate 1137, thus utilizing the impact force of the pipe to cushion it, further improving the cushioning effect. Meanwhile, the support spring 1133 provides elastic cushioning while simultaneously allowing the support shaft 1132 to return to its original position, ensuring the bearing effect of the central support member 113.

[0058] Preferably, the end of the support shaft 1132 that extends into the sliding cavity 1138 is provided with a limiting part, and the outer diameter of the limiting part is the same as the inner diameter of the sliding cavity 1138.

[0059] More preferably, the inner diameter of the sliding cavity 1138 at the bottom of the push opening 11311 is reduced, so that the sliding cavity 1138 abuts against the limiting part, thereby limiting the extension distance of the support shaft 1132. More preferably, the height of the support shaft 1132 gradually decreases with the height of the flexible shell 111, so that after the middle support member 113 supports the tube, the overall height gradually decreases, thereby allowing the tube to roll automatically after buffering.

[0060] Preferably, a self-aligning bearing (not shown in the figure) is provided on the push opening 11311, and the push rod 1136 passes through the center of the self-aligning bearing and is hinged to the bottom of the push arc plate 1137.

[0061] Furthermore, there is a gap between the bottom of the push-up arc plate 1137 and the bottom of the flexible shell 111. After setting the gap, the buffer particles 112 can flow along the gap during the unfolding or folding of the push-up arc plate 1137, so as to avoid the buffer particles 112 being unable to flow and causing the entire structure to jam.

[0062] In this embodiment, the buffer balance assembly 13 further includes a sliding track 135, which extends from the bottom of the fixed base 121 toward the flexible housing 111. The push plate 133 is provided with a sliding notch corresponding to the sliding track 135, and the push plate 133 moves back and forth along the sliding track 135.

[0063] Preferably, each receiving plate 122 is hinged to two sets of connecting columns 123, which are spaced apart along the second direction. Different sets of connecting columns 123 are each equipped with a corresponding fixed base 121, a buffer spring 124, and a buffer balance assembly 13. This arrangement allows the corresponding connecting column 123 to descend more quickly when the pipe deviates from its original position during descent, and enables the corresponding abutment rod 132 to push against the flexible shell 111 in time, allowing the flexible shell 111 to rise promptly and replace the receiving pipe. Simultaneously, the hinged arrangement of the receiving plate 122 allows it to tilt and rotate after receiving the pipe, forming an inclined surface after the pipe contacts the flexible shell 111, facilitating the pipe's removal from the vibration damping mechanism 1.

[0064] The present invention also provides a pipe buffer feeding device for conveying pipes, comprising:

[0065] The conveying body 2 is distributed along the first direction and has a conveying platform 21 on top;

[0066] The flipping module 3 includes a flipping arc plate 31, a telescopic push rod 32, and a triggering component 33. One side of the flipping arc plate 31 is rotatably connected to the conveying body 2, and the other side of the flipping arc plate 31 abuts against the conveying table 21. The two ends of the telescopic push rod 32 are respectively hinged to the middle of the conveying body 2 and the flipping arc plate 31. The triggering component 33 is located at the end of the conveying table 21. After the pipe moves along the flipping arc plate 31 to the triggering component 33, the triggering component 33 triggers the telescopic push rod 32 to move.

[0067] The receiving module 4 is set and located on the side where the conveying body 2 and the flipping module 3 are hinged. The receiving module 4 has a receiving channel 41, and the receiving channel 41 is provided with the vibration damping mechanism 1 as described above. The side wall of the receiving channel 41 is provided with a feeding opening corresponding to the vibration damping mechanism 1.

[0068] The control module is electrically connected to the flip module 3 and the receiving module 4.

[0069] Specifically, the trigger component 33 can adopt a structure such as a gravity sensor or an infrared sensor. After detecting the arrival of the pipe, it sends a signal to the control module, and the control module controls the telescopic push rod 32 to perform the action.

[0070] Specifically, the receiving module 4 can adopt a semi-enclosed structure formed by metal plates, and the internal cavity forms a receiving channel 41. A feed port is set at the top of the receiving channel 41, and the side wall of the receiving channel 41 is set to the discharge opening. The vibration damping mechanism 1 is set at the bottom of the receiving channel 41, and the pipe is guided and received through the receiving channel 41.

[0071] Specifically, those skilled in the art can, as needed, set multiple sets of vibration damping mechanisms 1 in the receiving channel 41, or adjust the length of the central buffer assembly 11 to adapt to the length of the pipe, without making specific limitations.

[0072] In this embodiment, the trigger assembly 33 includes a trigger ramp 331, a trigger spring 332, and a trigger member 333. One end of the trigger ramp 331 is hinged to the conveyor table 21 along its length. Both ends of the trigger member 333 are respectively hinged to the trigger ramp 331 and the conveyor table 21. The trigger spring 332 is sleeved on the trigger member 333 and disposed between the trigger ramp 331 and the conveyor table 21.

[0073] The height of the side of the trigger ramp 331 closest to the flipping arc plate 31 is lower than the height of the flipping arc plate 31. The trigger spring 332 and the trigger element 333 ensure that the height of the side of the trigger ramp 331 furthest from the flipping arc plate 31 is higher than the height of the flipping arc plate 31. This configuration ensures that the weight of the pipe is evenly transmitted to the trigger element 333 via the trigger ramp 331, allowing the trigger element 333 to activate after the pressure reaches the target level. The overall structure is simple and convenient, does not affect pipe transport, is easy to maintain, and provides sensitive and accurate triggering.

[0074] In this embodiment, the trigger 333 includes a fixed part 3331 and a telescopic part 3332. The fixed part 3331 has a trigger cavity 3333. One end of the telescopic part 3332 is hinged to the trigger ramp 331. The end of the telescopic part 3332 away from the trigger ramp 331 is disposed in the trigger cavity 3333 and slides along the trigger cavity 3333. A trigger button 3334 is provided at the bottom of the trigger cavity 3333. After the trigger ramp 331 is pressed and rotated, it drives the telescopic part 3332 to slide along the trigger cavity 3333. After the telescopic part 3332 slides to the end of the trigger cavity 3333, it abuts against the trigger button 3334 and triggers the trigger button 3334.

[0075] In this embodiment, the receiving channel 41 includes a wide-mouth section 411 and a descending section 412. The descending section 412 is located below the wide-mouth section 411, and the vibration damping mechanism 1 is located inside the descending section 412. A discharge cover plate 413 and a rotary motor 414 are provided on the discharge opening. The fixed end of the rotary motor 414 is located on the side wall of the descending section 412, and the output end of the rotary motor 414 is drivenly connected to the top of the discharge cover plate 413. The top of the discharge cover plate 413 is rotatably connected to the side wall of the discharge opening. The discharge cover plate 413 restricts the horizontal rolling of the pipe, preventing it from rolling out due to incomplete buffering, thus further improving safety. Simultaneously, the wide-mouth section 411 is generally funnel-shaped, guiding the pipe to the descending section 412 and preventing it from falling outside the receiving channel 41, further enhancing safety.

[0076] In this embodiment, a discharge platform 42 is provided on the outside of the discharge opening. The height of the discharge platform 42 gradually decreases from the side closer to the discharge platform 42 to the side farther away from the discharge platform 42. Guide arc plates 421 are provided on both sides of the discharge platform 42 in the first direction. The distance between the guide arc plates 421 gradually decreases from the end closer to the discharge platform 42 to the end farther away from the discharge platform 42.

[0077] In this embodiment, a distance sensor 14 is provided at the bottom of the fixed base 121. The distance sensor 14 is used to detect the displacement distance of the connecting column 123. After the distance sensor 14 is set, the displacement distance of the connecting column 123 detected by the distance sensor 14 triggers the opening or closing of the discharge cover 413, thereby opening the discharge cover 413 after the pipe is buffered and stabilized, ensuring overall safety.

[0078] Specifically, those skilled in the art can design and adjust the corresponding circuits and electrical connection methods as needed, without making specific limitations.

[0079] Preferably, the front end of the flipping module 3 is equipped with a conveying module. The conveying module can take various forms such as a conveyor belt or conveyor roller, so that the cut pipe is accelerated to be conveyed after contacting the conveying module and separated from the uncut pipe. There is no specific limitation. This setting can avoid interference when the flipping module 3 drives the pipe to flip and touches the uncut pipe, thus avoiding affecting the cutting process of the uncut pipe.
