Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0017] In the processing production line of pipes, bars, and other profiles, after the cutting process is completed, the cut pipes need to be received and transported to the next process in an orderly manner. Existing pipe cutting machines mostly rely on fixed slides or single conveyor lines for output. A set of receiving devices can usually only handle pipes within a specific length range. When long and short materials are mixed, they are prone to stacking and rolling, requiring cumbersome mechanical adjustments or even equipment replacement, which affects production efficiency. Moreover, long-distance conveyor lines usually have high power consumption. Even if only one short material is being transported, the entire large conveyor line needs to be started, resulting in energy waste and equipment wear.

[0018] Therefore, this utility model proposes an automatic receiving rack, referring to... Figures 1-5 It includes a first flip-plate receiving assembly 100 and two second flip-plate receiving assemblies 200 arranged sequentially along the cutting and discharge direction. It also includes a short material conveying assembly 300 located on the discharge end side of the first flip-plate receiving assembly 100 and a chain conveying assembly 400 arranged adjacent to and parallel to the short material conveying assembly 300. The length of the first flip-plate receiving assembly 100 is greater than the length of the second flip-plate receiving assembly 200. The short material conveying assembly 300 and the chain conveying assembly 400 are driven by independent third driving device 360 ​​and fourth driving device 410, respectively.

[0019] The first flip-plate receiving assembly 100 is longer than the second flip-plate receiving assembly 200 and is used to receive the pipe material sent from the cutting equipment. Depending on the length of the pipe material and subsequent feeding requirements, it can be flipped towards the short material conveying assembly 300 or the chain conveying assembly 400 under the action of the drive device, thus guiding the pipe material to the short material conveying assembly 300. The second flip-plate receiving assembly 200 cooperates with the first flip-plate receiving assembly 100 to form a stepped receiving area, jointly receiving the pipe material. When feeding longer materials, it flips towards the chain conveying assembly 400. The chain conveyor assembly 400 assists in smoothly rolling long materials into the chain conveyor assembly 400; the short material conveyor assembly 300 is driven by an independent third drive device 360, which is used to receive short materials flipped and delivered from the first flip-plate receiving assembly 100 and convey the short materials to the next process. It can operate independently when only short materials are being processed, avoiding unnecessary energy waste; the chain conveyor assembly 400 is adjacent to and parallel to the short material conveyor assembly 300, and is driven by a fourth drive device 410. When conveying long materials, it works together with the short material conveyor assembly 300 to smoothly send the long materials away. By setting up a first flip-plate receiving assembly 100 of different lengths and a shorter second flip-plate receiving assembly 200, a stepped receiving area is formed. Long materials will cross the first flip-plate receiving assembly 100 and the second flip-plate receiving assembly 200, while short materials will only fall on the first flip-plate receiving assembly 100. The equipment can adapt to a wide length range from short to long materials. The corresponding flip-plate action is controlled according to the actual flip-plate assembly covered by the pipe material, so that pipe materials of different lengths are guided into the designated conveyor line. The short material conveying assembly 300 and the chain conveying assembly 400 are driven by independent third drive device 360 ​​and fourth drive device 410. When only short materials need to be processed, only the short material conveying assembly 300 with lower power can be started, without having to start the long material chain conveying assembly 400 with higher power, which significantly reduces energy consumption and operating costs.

[0020] During operation, the cut pipe material is fed out from the upstream equipment and rolls into the receiving rack along the cutting and discharge direction. The pipe material is sequentially placed on the first flip-plate receiving assembly 100 and the second flip-plate receiving assembly 200. When short material needs to be delivered, the first flip-plate receiving assembly 100 flips towards the short material conveying assembly 300 under the action of the drive device, and the short material rolls directly into the short material conveying assembly 300. At this time, only the third drive device 360 ​​is activated, and the short material is sent away by the short material conveying assembly 300. When long material needs to be delivered, the first flip-plate receiving assembly 100 and the two second flip-plate receiving assemblies 200 flip towards the chain conveying assembly 400, so that the long material rolls smoothly into the chain conveying assembly 400. At this time, the third drive device 360 ​​and the fourth drive device 410 are activated, and the long material is sent away by the short material conveying assembly 300 and the chain conveying assembly 400 together. After the delivery is completed, all flip-plate receiving assemblies are reset to the horizontal receiving position, waiting to receive the next pipe material.

[0021] When the pipe material rolls in, the fixed position and unsuitable angle of the receiving plate may cause a large impact between the pipe material and the receiving plate, which may cause the pipe material to bounce up, slip down, or be placed in a messy and disorderly manner on the receiving plate, affecting the orderly progress of subsequent conveying. Therefore, in one embodiment, the first flip-plate receiving assembly 100 includes a first mounting frame 110, a first guide rail 120, a first slider 130, a first driving device 140, a first receiving plate 150, and two first cylinders 160. The first guide rail 120 is vertically mounted on the first mounting frame 110. The first slider 130 is slidably connected to the first guide rail 120. The first driving device 140 is mounted on the first mounting frame 110 and is used to drive the first slider 130 to reciprocate along the first guide rail 120. The fixed ends of the two first cylinders 160 are hinged to the side of the first slider 130 away from the first guide rail 120. The output ends of the two first cylinders 160 are respectively hinged to both ends of the bottom surface of the first receiving plate 150. One end of the first receiving plate 150 is hinged to the top of the first slider 130. The two first cylinders 160 are used to drive the first receiving plate 150 to swing around the hinge point between the first receiving plate 150 and the upper part of the first slider 130. The first driving device 140 controls the first slider 130 to reciprocate along the first guide rail 120 in the vertical direction. This allows for flexible adjustment of the height of the first receiving plate 150 according to actual conditions. Combined with two first cylinders 160 driving the first receiving plate 150 to swing along the hinge point, the receiving plate can better adapt to the tube material, thus achieving stable tube material reception and avoiding collisions or slippage due to improper reception. This ensures the accuracy of the tube material transfer process, improves the reliability of the entire material receiving and conveying process, and helps improve production efficiency. Specifically, the first driving device 140 includes a first motor, a first rack, and a first gear. The first motor is mounted on the first slider 130, the first rack is mounted on the first mounting bracket 110 and parallel to the first guide rail 120, and the first gear is located at the drive end of the first motor and rotates coaxially with the drive end of the first motor. The first gear meshes with the first rack. The first driving device 140 can also be a linear motor, a lead screw drive, or a linear cylinder.

[0022] When the tube rolls on the receiving plate, it relies entirely on the sliding friction between the tube and the receiving plate. This friction is relatively high, and the tube surface is prone to scratches, wear, and other damage, affecting the tube's appearance and quality. Therefore, in one embodiment, the first flip-plate receiving assembly 100 further includes a first groove 170, a first roller 180, and two first bearing seats 190. The first groove 170 is disposed on the first receiving plate 150, and its extension direction is perpendicular to the cutting and discharge direction. The two first bearing seats 190 are respectively fixed at both ends of the first groove 170. The two ends of the first roller 180 are respectively disposed on the two first bearing seats 190 and are rotatable relative to the first bearing seats 190. The upper side of the first roller 180 protrudes from the first groove 170. By setting a first groove 170 on the first receiving plate 150 and installing a first roller 180 that can rotate relative to it, when the tube rolls on the receiving plate, the tube contacts the roller, changing the original sliding friction between the tube and the receiving plate into rolling friction between the tube and the roller. This reduces the friction during the rolling process and can effectively prevent scratches and wear on the surface of the tube due to friction. It also reduces the wear on the surface of the receiving plate, extends the service life of the tube and the receiving plate, and reduces production costs. The smaller friction allows the tube to roll more smoothly and quickly on the receiving plate, reducing time delays caused by friction jamming.

[0023] Relying solely on the first flip-plate receiving component 100 for receiving and transferring long tubes may result in the tubes not connecting well with subsequent conveying components, which could easily lead to problems such as uneven transitions between receiving components, jamming, or falling during transfer to the conveying components. Therefore, in one embodiment, each second flip-plate receiving assembly 200 includes a second mounting frame 210, a second guide rail 220, a second slider 230, a second driving device 240, a second receiving plate 250, and a second cylinder 260. The second guide rail 220 is vertically mounted on the second mounting frame 210, and the second slider 230 is slidably connected to the second guide rail 220. The second driving device 240 is mounted on the second mounting frame 210 and is used to drive the second slider 230 to reciprocate along the second guide rail 220. The fixed end of the second cylinder 260 is hinged to the side of the second slider 230 away from the second guide rail 220, and the output end of the second cylinder 260 is hinged to the middle of the bottom surface of the second receiving plate 250. One end of the second receiving plate 250 is hinged to the top of the second slider 230, and the second cylinder 260 is used to drive the second receiving plate 250 to swing along the hinge point between the second receiving plate 250 and the upper part of the second slider 230. The second flip-plate receiving assembly 200 uses a single second cylinder 260 to drive the swing of the second receiving plate 250. While ensuring the completion of long pipe material receiving and conveying operations, it reduces the number of components and complexity, thereby lowering manufacturing costs and potential subsequent maintenance costs. The second flip-plate receiving assembly 200 and the first flip-plate receiving assembly 100 work together to form a stepped receiving layout, effectively accommodating longer pipe materials. During the long pipe material conveying process, it can accurately perform corresponding actions according to the overall workflow requirements, ensuring smooth operation of each stage from receiving, dwelling to transfer of the long pipe material, ensuring the operational reliability of the entire receiving and conveying process, and helping to improve the overall operating efficiency of the production line. Specifically, the second drive device 240 includes a second motor, a second rack, and a second gear. The second motor is mounted on the second slider 230, the second rack is mounted on the second mounting bracket 210 and parallel to the second guide rail 220, and the second gear is located at the drive end of the second motor and rotates coaxially with the drive end of the second motor. The second gear meshes with the second rack. The second drive device 240 can also be configured as a linear motor, a lead screw drive device, or a linear cylinder.

[0024] When the tube rolls on the receiving plate, it relies entirely on the sliding friction between the tube and the receiving plate. This friction is relatively high, and the tube surface is prone to scratches, wear, and other damage, affecting the tube's appearance and quality. Therefore, in one embodiment, the second flip-plate receiving assembly 200 further includes a second roller groove 270, a second roller 280, and two second bearing seats 290. The second roller groove 270 is disposed on the second receiving plate 250, and its extension direction is perpendicular to the cutting and discharge direction. The two second bearing seats 290 are respectively fixed at both ends of the second roller groove 270. The two ends of the second roller 280 are respectively disposed on the two second bearing seats 290 and are rotatable relative to the second bearing seats 290. The upper side of the second roller 280 protrudes from the second roller groove 270. By setting a second groove 270 on the second receiving plate 250 and installing a second roller 280 that can rotate relative to it, when the short pipe rolls on the second receiving plate 250, the pipe contacts the roller, and the original sliding friction between the pipe and the receiving plate is transformed into rolling friction between the pipe and the roller. This reduces the resistance during the rolling process of the pipe, allowing the short pipe to roll more smoothly on the receiving plate and avoiding jamming caused by excessive friction.

[0025] The conveying of short pipe materials may fail to achieve continuous and stable conveying due to uneven power transmission, lack of effective load-bearing and guiding, etc. Therefore, in one embodiment, the short material conveying assembly 300 includes a first frame 310, a first rotating shaft 320, a second rotating shaft 321, a first sprocket 330, a second sprocket 331, a third sprocket 332, a fourth sprocket 333, a first conveying chain 340, a second conveying chain 341, a chain plate assembly 350, and a third drive device 360; the first rotating shaft 320 is disposed at the feed end of the first frame 310 and can rotate relative to the first frame 310; the first sprocket 330 and the second sprocket 331 are respectively sleeved on both ends of the first rotating shaft 320 and coaxially rotate with the first rotating shaft 320; the second rotating shaft 321 is disposed at the discharge end of the first frame 310 and can rotate relative to the first frame 310; the third sprocket 330... The first conveyor chain 340 is wound around the first conveyor chain 330 and the third conveyor chain 332, and the second conveyor chain 341 is wound around the second conveyor chain 331 and the fourth conveyor chain 333. The chain plate assembly 350 is disposed between the first conveyor chain 340 and the second conveyor chain 341. The feed end of the chain plate assembly 350 is located below the discharge end of the first flip plate receiving assembly 100. The third drive device 360 ​​is disposed on the first frame 310. The third drive device 360 ​​is connected to the second conveyor shaft 321 and is used to drive the short material conveying assembly 300 to convey the tube material. The short pipe material sliding down from the first flip-plate receiving assembly 100 can land on the chain plate assembly 350. As the chain rotates, it is continuously conveyed forward, avoiding interruptions in the conveying process and ensuring the continuity of the short pipe material conveying. The feed end of the chain plate assembly 350 is located below the discharge end of the first flip-plate receiving assembly 100, so that after the short pipe material flips out from the first flip-plate receiving assembly 100, it can fall accurately and smoothly onto the short material conveying assembly 300. This realizes the connection between the receiving and conveying links, reduces jamming and errors in the pipe material transfer process, and helps the entire production process to run more smoothly, thereby improving production efficiency. Specifically, the third drive device 360 ​​includes a third motor 361, a first drive wheel 362, a first power chain 363, and a first driven wheel 364. The third motor 361 is mounted on the first frame 310. The first drive wheel 362 is coaxially rotatable with the drive unit of the third motor 361. The first drive wheel 362 is connected to the first driven wheel 364 via the first power chain 363. The first driven wheel 364 is coaxially rotatable with the second rotating shaft 321. The third drive device 360 ​​can also be a gear drive structure or a belt drive structure.

[0026] Long pipes are prone to rolling on the conveyor chain due to their own inertia and slight shaking during chain operation, which may result in the pipes falling off the chain or significant positional deviation during the conveying process. Therefore, in one embodiment, the chain conveyor assembly 400 includes a fourth drive device 410, a coupling 420, a synchronous shaft 430, and multiple sets of feeding assemblies 440 arranged at intervals. Each set of feeding assemblies 440 includes a second frame 441, a third rotating shaft 442, a fourth rotating shaft 443, a fifth sprocket 444, a sixth sprocket 445, a third conveyor chain 446, a limiting plate 447, and multiple limiting blocks 448. The third rotating shaft 442 is located at the feeding end of the second frame 441 and can rotate relative to the second frame 441. The fifth sprocket 444 is sleeved on the third rotating shaft 442 and rotates coaxially with the third rotating shaft 442. The fourth rotating shaft 443 is located at the discharge end of the second frame 441 and can rotate relative to the second frame 441. The sixth sprocket 445 is sleeved on the fourth rotating shaft 443 and rotates coaxially with the fourth rotating shaft 443. The third conveying chain 446 is wound around the fifth sprocket 444 and the sixth sprocket 445. All the limiting blocks 448 are spaced apart on the outer surface of the third conveying chain 446. The limiting blocks 448 are used to abut against the pipe material. The limiting plate 447 is set at the discharge end of the second frame 441. The limiting plate 447 is used to prevent the pipe material from rolling out of the second frame 441 due to inertia. The fourth driving device 410 is connected to the synchronous shaft 430. The two ends of the synchronous shaft 430 are respectively connected to two adjacent third rotating shafts 442 through the coupling 420. The fourth driving device 410 is used to drive the feeding assembly 440 to transmit the pipe material. By setting limit blocks 448 and limit plates 447, the limit blocks 448 are spaced apart on the outer surface of the third conveyor chain 446, and can abut against the pipe material, playing a limiting and supporting role for the long pipe material during the conveying process, preventing it from rolling randomly; the limit plates 447 are set at the discharge end of the second frame 441, which can effectively prevent the pipe material from rolling out of the second frame 441 due to inertia, enhancing the stability of the long pipe material during the conveying process, avoiding problems such as pipe material falling off or shifting, and ensuring the safety and accuracy of the conveying; multiple sets of feeding Component 440 is linked by synchronous shaft 430. The two ends of synchronous shaft 430 are respectively connected to two adjacent third rotating shafts 442 through couplings 420. With the drive of the fourth drive device 410, it can ensure that all feeding components 440 operate synchronously, so that the long tube material is evenly stressed throughout the entire chain conveyor component 400, which further consolidates the stable conveying of the tube material and avoids problems such as tube material jamming and twisting caused by asynchrony, thus ensuring the continuity and efficiency of the long tube material conveying process.Specifically, the fourth drive device 410 includes a fourth motor 411, a second drive wheel 412, a second power chain 413, and a second driven wheel 414. The fourth motor 411 is mounted on the second frame 441. The second drive wheel 412 is coaxially rotatable with the drive unit of the fourth motor 411. The second drive wheel 412 is connected to the second driven wheel 414 via the second power chain 413. The second driven wheel 414 is coaxially rotatable with the third rotating shaft 442. The fourth drive device 410 can also be a gear drive structure or a belt drive structure.

[0027] If the tubular material cannot be discharged in time when it is conveyed to the discharge end, it is easy for the material to accumulate at the discharge end, which can lead to blockage. Therefore, in one embodiment, the chain conveyor assembly 400 further includes a sensing assembly 500, which includes a material pressure plate 510, a sensing switch 520, and a torsion spring. The sensing switch 520 is disposed on the discharge end of one of the second frames 441 near the short material conveyor assembly 300. The material pressure plate 510 is repositionably connected to the sensing switch 520 through the torsion spring. The material pressure plate 510 is used to press down and cause a change in the internal contact point of the sensing switch 520. The torsion spring has a tendency to move the material pressure plate 510 away from the sensing switch 520. The end of the material pressure plate 510 away from the sensing switch 520 is inclined upward. The highest end of the material pressure plate 510 is higher than the upper surface of the chain conveyor assembly 400. The sensing switch 520 is electrically connected to the fourth drive device 410. By using the material pressure plate 510, the inductive switch 520, and the torsion spring, the presence of tube material on the discharge end of the chain conveyor assembly 400 can be detected. When the tube material reaches the corresponding position, the material pressure plate 510 is pressed down, causing the internal contact point of the inductive switch 520 to change. This, in turn, controls the start and stop of the fourth drive device 410 via an electrical signal, eliminating the need for manual intervention and improving production efficiency. With the electrical connection between the inductive switch 520 and the fourth drive device 410, when the tube material is conveyed to the material pressure plate 510 at the discharge end, the conveying can be stopped in time to prevent the tube material from continuing to accumulate and causing blockage of the conveying assembly. This ensures the smoothness of the conveying process and the normal operation of the equipment, reducing production delays caused by equipment failure or abnormal shutdown.
