When the feeding mobile frame 101 moves along the first moving track when unloaded, the floating support roller is retracted to avoid interference with the movement of the feeding mobile frame 101; when the feeding mobile frame 101 moves along the first moving track when loaded, the floating support roller descends to contact and cooperate with the support bed to play an auxiliary support role.

[0032] In a preferred example, the feeding device in the present application is also provided with an arrangement drive, Figure 3 The difference from the structure shown is that the base 102 in this preferred example is no longer fixed by anchor screws or other fixings, but can be moved along the axial direction of the pipe under the drive of the arrangement drive, so as to facilitate the automatic adjustment of the number of feeding components 1 used and the arrangement interval to meet the feeding requirements of pipes 4 to be cut of different lengths and weights. It should be noted here that the present application does not specifically limit the specific type of arrangement drive and the connection method between it and the base, and it can refer to the conventional drive structure in the prior art.

[0033] In the above scheme, the feeding mobile frame 101 and the base 102 are provided with multiple, that is, multiple groups of feeding components 1 are provided, and the multiple groups of feeding components 1 can be arranged along the axial direction of the pipe 4 to be cut, so that different numbers of feeding components 1 can be adaptively allocated according to the length and weight of the pipe 4 to be cut to meet the requirements of load capacity and bearing size, which can not only realize the automatic loading of heavy pipes 4 but also realize the combined loading of pipes 4 of various specifications and sizes, greatly improving the processing efficiency. At the same time, by arranging a support structure at the front end of the feeding mobile frame 101, it can play an auxiliary supporting role for the feeding mobile frame 101 during the feeding process, preventing the feeding device 1 from being deformed due to the large force on the front end of the pipe 4 being too heavy, thereby ensuring the safety of the equipment itself and the pipe 4.

Preferably, the aforementioned centering drive 206 is a driving cylinder, and the second lifting drive 205 is a lifting cylinder. At the same time, as a preferred embodiment of the present application, the first lifting drive includes a lifting motor 204 and a lifting reducer 203 coordinated with the lifting motor 204, a rack is provided on the lifting track, and the clamping and centering mechanism 200 is provided with a gear meshing with the rack, and the gear cooperates with the lifting reducer 203.

[0035] In the above scheme, the centering clamping assembly can move relative to the feeding mobile frame 101 in the vertical direction under the action of the first lifting drive and the second lifting drive 205, and the aforementioned clamping member can also clamp the pipe 4 and realize horizontal movement under the action of the centering drive 206, so that the height of the support roller and the horizontal position of the clamping plate 207 and the clamping roller 202 can be adjusted according to the shape and size of the pipe 4, so as to ensure that the center height of the pipe 4 is consistent with the clamping center height of the laser pipe cutting machine chuck and realize the centering positioning of the pipe 4 and the cutting device, thereby ensuring the processing accuracy. Moreover, in the above scheme, since the first lifting drive adopts the lifting motor 204 in conjunction with the lifting reducer 203 and the gear rack transmission structure, the height can be finely adjusted by the first lifting drive after the height is roughly adjusted by the lifting cylinder, so as to further ensure the centering accuracy, ensure the successful clamping of the laser pipe cutting machine chuck on the pipe 4, and be more conducive to ensuring the processing accuracy.

Through the cooperation of the controller with the above-mentioned pipe 4 detection device, the drive device, and the drive structure, the combined feeding of heavy-duty pipes 4 of various specifications and sizes can be realized.

[0037] For example, the pipe 4 can be divided into zones and combined for loading according to its length range. The length of the pipe 4 can be input into the controller in advance or the length of the pipe 4 can be automatically measured by the pipe 4 detection device. The controller can select the number of feeding mobile racks 101 to be used according to its length, thereby realizing zone loading. When the length of the pipe 4 is ≤L1, two groups of feeding components 1 can be used for loading; when L1<the length of the pipe 4 ≤L2, three groups of feeding components 1 can be used for combined loading; when the length of the pipe 4 is>L2, four groups of feeding components 1 can be used for combined loading. Different lengths of zoned combined loading can be realized.
