[0024] The first vertical beam 12 is towards the chuck laser pipe cutting machine and is fixedly connected with the bed body of the chuck laser pipe cutting machine. A supporting and supporting mechanism is arranged between adjacent feeding assemblies. The plurality of feeding assemblies are used for supporting the pipe material. The pipe material is limited in the storage cartridge to avoid displacement of the pipe material. In actual application, the pipe material is fed from the rear of the cross beam 11 (the direction of the second vertical beam 13). The pipe material is conveyed to the direction of the first vertical beam 12 (the front) by the rotation of the transport chain 23. After the pipe material is in place, the supporting and supporting mechanism lifts the pipe material to be coaxial with the chuck of the chuck laser pipe cutting machine. The rotation driving device 4 is operated again to realize continuous feeding of the pipe material.

[0025] The rotation driving device 4 is arranged away from the bed body, that is, the operation side. Therefore, the rotation driving device 4 is covered in the protective cover 6, which can be used to protect the operator on the operation side. The protective cover 6 is connected with the cross beam 11, the second vertical beam 13 and the connecting rod 5 to ensure that the protective cover 6 is stably installed on the feeding assembly.

[0026] Specifically, the driving wheel 21 is a first sprocket, and the driven wheel 22 is a second sprocket.

[0027] More specifically, the feeding rack in the embodiment is composed of four groups of feeding assemblies. Each group of feeding assemblies adopts a detachable design, occupies a small space, and is convenient for disassembly and transportation.

[0028] Please refer to Figure 2 and Figure 3 In some embodiments, the driving wheel 21 is sleeved on the rotating shaft 211.

One end of the rotating shaft 211 is connected with the transmission shaft 31 through the universal joint coupling 32. That is, when one of the rotating shafts 211 rotates, the power is transmitted to the other rotating shaft 211 through the universal joint coupling 32, the transmission shaft 31 and the universal joint coupling 32 in sequence. The universal joint coupling 32 can compensate for the misalignment caused by the angle deviation or displacement between the two rotating shafts 211, so that the two rotating shafts 211 can remain connected and transmit torque, reducing the strict requirements for axis pairing.

[0029] Please refer to Figure 3In some embodiments, the rotating driving device 4 comprises a motor support 41, a driving motor 42 arranged on the motor support 41, a driving sprocket 43 arranged on the output end of the driving motor 42, a driven sprocket 44 sleeved on one of the rotating shafts 211, and a driving chain 45 arranged between the driving sprocket 43 and the driven sprocket 44. When transporting the pipe, the driving motor 42 drives the driving sprocket 43 to rotate, and under the transmission of the driving chain 45 and the driven sprocket 44, the rotating shaft 211 is driven to rotate, and then the driving wheel 21 on the rotating shaft 211 is driven to rotate, thereby providing power for the transportation chain 23.

[0030] Referring to Figure 2 In some embodiments, the protective cover 6 comprises a motor cover 61 and a transmission cover 62 in communication with the inner cavity of the motor cover 61; the motor support 41 and the driving motor 42 are arranged inside the motor cover 61; the driving sprocket 43, the driven sprocket 44 and the driving chain 45 are arranged inside the transmission cover 62. The protective cover 6 is divided into two parts, which facilitates the preparation of sheet metal parts, reduces the manufacturing difficulty, and makes the shape of the protective cover 6 more suitable for the shape of the rotating driving device 4, thereby reducing the occupied space of the rotating driving device 4.

[0031] Referring to Figure 2 In some embodiments, the upper part of the motor cover 61 is provided with two first mounting lugs 611, the lower part of the motor cover 61 is provided with two second mounting lugs 612, the two first mounting lugs 611 are respectively fixedly connected with the left side wall / right side wall of the cross beam 11, and the two second mounting lugs 612 are respectively used for being fixedly connected with the side wall of the adjacent connecting rod 5; the transmission cover 62 is provided with a third mounting lug 621, and the third mounting lug 621 is fixedly connected with the side wall of the second vertical beam 13. Specifically, the protective cover 6 is fixed by screwing screws / screws into the corresponding mounting lugs. More specifically, a waist-shaped hole is formed in each mounting lug, thereby facilitating the fine adjustment of the position of the protective cover 6 relative to the rotating driving device 4 and facilitating the installation.

[0032] Referring to Figure 2 In some embodiments, the motor cover 61 is provided with an inspection hole, and a detachable cover plate 613 is arranged in the inspection hole. Through the above arrangement, the rotating driving device 4 can be exposed by opening the cover plate 613, thereby facilitating maintenance without disassembling the entire protective cover 6.

[0033] Referring to Figure 2In some embodiments, the rear end of the cross beam 11 is provided with a protective plate 14 for shielding the rear end of the driving wheel 21. The rear end is the operating side, and the protective plate 14 can shield the driving wheel 21, thereby further avoiding the clothes or other objects from being rolled in.

[0034] Referring to Figure 1 and Figure 4 In some embodiments, the front end of the cross beam 11 is provided with two shaft limiting plates 15, which are respectively fixed to the left and right side walls of the cross beam 11. The two shaft limiting plates 15 are used to block the further forward conveying of the pipe material, and a stroke sensing mechanism 7 is arranged behind the shaft limiting plates 15 for sensing the pipe material. In order to automatically detect whether the pipe material is transported to the set position, the stroke sensing mechanism 7 is arranged, and when the pipe material touches the stroke sensing mechanism 7, it represents that the pipe material is transported to the position. At this time, the stroke sensing mechanism 7 feeds back a signal to the control system, and the control system controls the rotary driving device 4 to stop working until the pipe material is clamped and fed, and the rotary driving device 4 is restarted to realize the automatic feeding and conveying of the next pipe material. The arrangement of the shaft limiting plate 15 can avoid the pipe material from easily sliding / rolling out of the feeding assembly due to the inertia of the forward movement of the pipe material. The shaft limiting plate 15 is used to limit the movement of the pipe material and improve the safety.

[0035] Referring to Figure 4 In some embodiments, the stroke sensing mechanism 7 includes a support plate 71 fixed to the side wall of the cross beam 11, a stroke switch 72 arranged on the support plate 71, and a feeding pressure plate 73 arranged at the output end of the stroke switch 72. Specifically, when the pipe material is conveyed to the position of the feeding pressure plate 73, the feeding pressure plate 73 is pressed down to touch the stroke switch 72, and the control system controls the supporting and feeding mechanism to operate to support the pipe material, thereby facilitating the clamping of the pipe material by the chuck.

[0036] Referring to Figure 4 In some embodiments, a photoelectric sensor 81 (the mounting plate of the photoelectric sensor 81 is indicated in the figure) is further arranged behind the feeding pressure plate 73. The sensing sheet 82 is fixed to the conveying chain 23, and the photoelectric sensor 81 is used to sense the sensing sheet 82. When the sensing sheet 82 passes the position of the photoelectric sensor 81, the conveying chain 23 stops moving, and after the supporting and feeding mechanism lifts the pipe material, the conveying chain 23 continues to move.

[0037] In summary, the protective cover 6 is arranged to cover the rotary driving device 4, which can be used to protect the operator located on the operating side. Moreover, the protective cover 6 is connected to the cross beam 11, the second vertical beam 13 and the connecting rod 5 in a three-point connection manner, which can ensure that the protective cover 6 is stably installed on the feeding assembly.
