[0002] For example, the receiving rack with publication number CN216730818U uses a vertical motion mechanism to drive the support frame to move up and down, so that the receiving plate moves up and down to support the pipe. At the same time, the swing mechanism is used to drive the receiving plate to swing and tilt, so as to roll the processed and cut pipe onto the placement rack. However, since the length and weight of the pipes cut by the chuck laser cutting machine are different, it is difficult to limit the rolling of the pipe for the rolling unloading method, such as the rolling speed and rolling path, which is not safe.
[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Detailed Implementation
[0022] This utility model provides a chain splicing assembly. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.
[0023] Please see Figure 1This utility model provides a chain receiving assembly, including multiple receiving frames arranged in parallel left and right. Each receiving frame includes a frame 1, a drive wheel 21 and a driven wheel 22 rotatably mounted on the frame 1, and a transport chain 23 wound between the drive wheel 21 and the driven wheel 22. Multiple limiting blocks 24 are provided on the outer surface of the transport chain 23, and a storage slot is formed between two adjacent limiting blocks 24. The drive wheels 21 on the multiple receiving frames are connected by a drive shaft 31, and the drive shaft 31 is driven by a rotation drive device 4. A limiting plate 15 is provided at the downstream end of the frame 1, and the limiting plate 15 is used to block the pipe from being transported further downstream.
[0024] In practical applications, multiple receiving racks are spaced apart on the left and right, and receiving structures are provided in the space between adjacent receiving racks. Multiple receiving structures support the pipes and can unload the cut pipes, transferring them to the upstream of the crossbeam 11. The provided storage bays can be used to restrict the movement of the pipes. As the pipes are unloaded, under the action of the rotation drive device 4, the drive wheel 21 and driven wheel 22 are used to rotate the transport chain 23 from the upstream direction to the downstream direction, so that the pipes on each storage bay can be transported downstream one by one. When the pipes are transported to the position of the axis limiting plate 15 at the downstream end, the axis limiting plate 15 can prevent the pipes from easily sliding / rolling out of the receiving rack due to the inertia of the pipes moving downstream, thus restricting the pipes to the downstream end, waiting for unloading.
[0025] Specifically, the driving wheel 21 is the first sprocket, and the driven wheel 22 is the second sprocket.
[0026] In the above configuration, by separating the receiving structure and the receiving rack, the space occupied by the receiving structure can be reduced, and it is also convenient for shipment and transportation. In addition, the material storage bay formed by the transport chain 23 and the limiting block 24 is used to store the pipe and prevent the pipe from shifting during transportation; and the limiting plate 15 located at the downstream end is used to limit the movement of the pipe and ensure that the pipe is transported smoothly downstream.
[0027] Please see Figure 1In some embodiments, the frame 1 includes a crossbeam 11 parallel to the pipe conveying direction, a first vertical beam 12 fixed to the lower surface of the crossbeam 11 in the upstream direction, and a second vertical beam 13 fixed to the lower surface of the crossbeam 11 in the downstream direction; multiple second vertical beams 13 are connected by connecting rods 5; a fixing plate 113 is provided on the side wall of the crossbeam 11 in the upstream direction, the fixing plate 113 is used to fix the frame 1 to the side wall of the bed; the crossbeam 11 has a slot 111 in the upstream direction, and the driven wheel 22 is rotatably disposed in the slot 111. Specifically, a base plate is also provided on the lower surface of the second vertical beam 13, and an adjusting foot cup is provided on the base plate. By using the oblong holes on the fixing plate 113, screws are driven in to fix the frame 1 to the side wall of the bed one by one, making installation and disassembly very convenient. In addition, the crossbeam 11, the first vertical beam 12 and the second vertical beam 13 are all made of square tubing, which is easy to obtain and has low cost. The slot 111 provides installation space for the driven wheel 22.
[0028] Please see Figure 1 In some embodiments, the slot 111 divides the crossbeam 11 into an extension section and a receiving section; the extension section is located upstream of the slot 111, and the receiving section is located downstream of the slot 111. As described above, a receiving structure is provided between the two receiving racks, and this receiving structure is located upstream of the two receiving racks. The purpose of the extension section is to enable the frame 1 to form a stable connection with the bed, and the tubing received on the receiving structure is transferred to the upstream position of the transport chain 23 for further conveying.
[0029] Please see Figure 1 In some embodiments, a reinforcing beam 14 is also fixedly connected to the side wall of the first vertical beam 12. The reinforcing beam 14 is perpendicular to the extension direction of the crossbeam 11, and the reinforcing beam 14 is used to fix the frame 1 to the reinforcing side seat of the bed. In this embodiment, the upstream of the crossbeam 11 is connected to the bed, and the reinforcing beam 14 is connected to the reinforcing side seat on the bed again, thereby further strengthening the connection stability between the receiving rack and the bed.
[0030] Please see Figure 1 and Figure 2In some embodiments, the drive wheel 21 is mounted on a rotating shaft 211, which is connected to the crossbeam 11 via two bearings 212. One end of the rotating shaft 211 is connected to the drive shaft 31 via a universal joint coupling 32. That is, when one rotating shaft 211 rotates, power is transmitted sequentially to the other rotating shaft 211 via the universal joint coupling 32, the drive shaft 31, and the universal joint coupling 32 again. The universal joint coupling 32 can compensate for misalignment caused by angular deviation or displacement between the axes of the two rotating shafts 211, ensuring that the two rotating shafts 211 remain connected and transmit torque, reducing the stringent requirements for shaft matching.
[0031] Please see Figure 2 In some embodiments, the rotation drive device 4 includes a motor bracket 41, a drive motor 42 mounted on the motor bracket 41, a drive sprocket 43 mounted on the output end of the drive motor 42, a driven sprocket 44 sleeved on one of the rotating shafts 211, and a drive chain 45 wound between the drive sprocket 43 and the driven sprocket 44. When transporting the pipe, the drive motor 42 drives the drive sprocket 43 to rotate, which, under the transmission of the drive chain 45 and the driven sprocket 44, drives the rotating shaft 211 to rotate, thereby driving the drive wheel 21 on the rotating shaft 211 to rotate, providing power to the transport chain 23.
[0032] Please see Figure 3 In some embodiments, the driven wheel 22 is mounted on the adjusting shaft 62 via a bearing 61. The adjusting shaft 62 has a stop surface 621 on its peripheral wall at both ends, and a tension threaded hole is provided on the stop surface 621. A fixing block 63 is provided on each of the two sides of the crossbeam 11. A tension screw 64, which mates with the tension threaded hole, passes through each fixing block 63. The head of the tension screw 64 presses against the fixing block 63, and the screw portion of the tension screw 64 is connected to the tension threaded hole. A tightening nut 65 is threaded onto the tension screw 64. The tightening nut 65 and the head of the tightening screw 64 together clamp the fixing block 63. The engagement of the tension screw 64 with the tension threaded hole allows the operator to adjust the position of the driven sprocket 44 by rotating the tightening nut 65, thereby finely adjusting the tension of the transport chain 23. This ensures that the transport chain 23 maintains proper tension even after prolonged use, avoiding slippage caused by an overly loose transport chain 23 or additional wear caused by an overly tight transport chain 23.
[0033] Please see Figure 1 and Figure 3In some embodiments, the left and right side walls of the crossbeam 11 are respectively provided with U-shaped grooves 112 communicating with the slots 111, and the two ends of the adjusting support shaft 62 pass through the corresponding U-shaped grooves 112; a limiting block 66 is detachably provided on the left and right side walls of the crossbeam 11, and both limiting blocks 66 are located above the ends of the adjusting support shaft 62. The upper part of the U-shaped groove 112 is designed to be open, so as to facilitate the insertion of the adjusting support shaft 62 from top to bottom into the U-shaped groove 112 and the slot 111, which is convenient for installation. Then, the limiting blocks 66 are used to limit the movement of the adjusting support shaft 62 above, so as to prevent the driven wheel 22, which is rotatably connected to the adjusting support shaft 62, from falling out of the slot 111.
[0034] Please see Figure 1 and Figure 2 In some embodiments, a stroke sensing mechanism 7 for sensing the pipe is further provided upstream of the axis limiting plate 15. The stroke sensing mechanism 7 is electrically connected to the rotation drive device 4. The stroke sensing mechanism 7 includes a support plate 71 fixed on the side wall of the crossbeam 11, a limit switch 72 provided on the support plate 71, and a material receiving pressure plate 73 provided on the output end of the limit switch 72. This stroke sensing mechanism 7 is provided to automatically detect whether the pipe has been transported to the set position. When the pipe triggers the stroke sensing mechanism 7, it indicates that the pipe has been transported to the correct position. At this time, the stroke sensing mechanism 7 sends a feedback signal to the control system, which then controls the rotation drive device 4 to stop working until the pipe is unloaded. The rotation drive device 4 then restarts to achieve automatic receiving and transport of the next pipe. Specifically, when the pipe is transported to the position of the material receiving pressure plate 73, the material receiving pressure plate 73 presses down, triggering the limit switch 72. The control system then controls the rotation drive device 4 to stop transporting the pipe. After the pipe is unloaded and transferred away from the frame 1, the rotation drive device 4 resumes operation.
[0035] Please see Figure 2 In some embodiments, a photoelectric sensor 81 (the mounting plate of the photoelectric sensor 81 is shown in the figure) is also provided upstream of the material receiving plate 73. A sensing plate 82 is fixedly connected to the conveyor chain 23, and the photoelectric sensor 81 is used to sense the sensing plate 82. When the sensing plate 82 passes the position of the photoelectric sensor 81, the conveyor chain 23 stops moving. After the pipe at the downstream end of the conveyor chain 23 is unloaded, the receiving structure will transfer the next pipe to the upstream of the conveyor chain 23.
[0036] Please see Figure 1 In some embodiments, a receiving box 9 is provided next to the receiving rack near the laser cutting assembly. The receiving box 9 is used to receive tail material / short tubes. This location is within the cutting area, and the short tube receiving structure provides follow-up support and receiving for the tail material / short tubes, facilitating the transfer of the tail material / short tubes to the receiving box 9 without the need for conveying via the receiving rack.
[0037] In summary, this utility model utilizes the storage bay formed by the transport chain 23 and the limiting block 24 to store the pipe material, preventing the pipe material from shifting during transport; and utilizes the limiting plate 15 located at the downstream end to ensure that the pipe is transported smoothly downstream.
