[0002] The feeding mechanism of the laser tube cutting machine is an extremely critical part of the entire equipment. It is mainly responsible for accurately conveying the tube to the cutting area. The feeding mechanism usually includes a driving device, which provides stable and continuous power for the transportation of the tube, ensuring that the tube can move at the set speed and direction. There is also a clamping device, which can effectively clamp the tube to avoid the tube sliding or position shifting during the feeding process, thereby ensuring the feeding accuracy. When the cutting task is started, the driving device starts to operate under the command of the control system, driving the transmission components, so that the tube clamped by the clamping device is pushed forward at a stable speed, and the tube is accurately delivered to the predetermined position under the laser cutting head. During the cutting process, the position of the tube can be adjusted in time according to the cutting progress and requirements to ensure that the cutting work can be completed smoothly and accurately, meeting different cutting processes and tube processing requirements.

[0003] The existing support mechanism is a single set of single wheels, and the centering mechanism is a gear rack double meshing method or a pull-connecting rod structure to achieve the centering function. Single-wheel support has a small support surface for small tubes, and both ends are prone to sagging. The centering structure is relatively complex and large in size. Therefore, it is necessary to develop a synchronous centering support mechanism that can improve the support performance. Summary of the invention

[0014] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0016] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the synchronous swing arm 6 is horizontally projected into a Z shape.

[0017] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the horizontal conveying assembly is symmetrically arranged on both sides of the synchronous centering assembly, including a flat roller shaft 2 and a flat roller 3. The flat roller shaft 2 is rotatably connected to the base 1, and the flat roller 3 is connected to the flat roller shaft 2.

[0018] like Figure 1 , Figure 4 and Figure 5 As shown, the clamping assembly includes a vertical roller shaft 11 and a clamping roller 12 . The vertical roller shaft 11 is connected to the sliding bracket 9 , and the clamping roller 12 is connected to the vertical roller shaft 11 .

[0019] like Figure 2 and Figure 3 As shown, the swing mechanism includes a swing shaft 13 and an arc-shaped slide groove 101 . The swing shaft 13 is connected to the synchronous swing arm 6 . The arc-shaped slide groove 101 is arranged on the base 1 and matches the swing shaft 13 .

[0020] like Figure 3 and Figure 6 As shown, a cylinder 14 is provided on the side of the base 1 away from the synchronous centering component, and the cylinder 14 is connected to the base 1 through a hinge seat 15. A fisheye joint 16 is provided on the output shaft of the cylinder 14, and the fisheye joint 16 is rotatably connected to the swing shaft 13.

[0021] Principle and operation process The crank connecting rod 7 mechanism of the present invention is the core component for realizing synchronous centering. When the central rotating shaft 4 is fixed on the base 1, the synchronous swing arm 6 rotates around the central rotating shaft 4. The synchronous swing arm 6 is powered by the swing mechanism, so that the synchronous swing arm 6 swings. Since the guide rails 5 are symmetrically arranged on both sides of the synchronous swing arm 6 and are perpendicular to the conveying direction of the horizontal conveying assembly, when the synchronous swing arm 6 swings, the slider 10 is driven to slide on the guide rail 5 through the connecting rod 7. Because it is centrally symmetrical and moves synchronously, synchronous centering can be realized. When the synchronous swing arm 6 swings to one side, the slider 10 on one side will be pulled to move toward the center through the connecting rod 7, and the slider 10 on the other side will also be pushed to move toward the center, thereby realizing centering; the synchronous swing arm 6 is designed into a Z shape, which can make the two ends more labor-saving when driving the connecting rod 7 to move. When the force acts on the end points of the Z-shaped synchronous swing arm 6, the force transmission is smoother, which can more effectively drive the connecting rod 7 to move, and then drive the slider 10 to slide on the guide rail 5. Moreover, the Z-shaped design can also avoid the jamming that may be caused when the synchronous swing arm 6 is in a completely vertical state with the guide rail 5. Because in a completely vertical state, the movement may be unsmooth due to factors such as friction, and the Z-shaped design changes the angle and mode of force action, thereby improving the stability of use.

[0022] By symmetrically arranging the horizontal conveying assembly on both sides of the synchronous centering assembly, during the material conveying process, the flat roller shafts 2 and flat rollers 3 on both sides act simultaneously to provide uniform support and conveying force for the material. The horizontal conveying assembly can be used in conjunction with a power device. When the material is placed on the flat roller 3, the flat roller shaft 2 rotates to drive the flat roller 3 to rotate, so that the material can be smoothly conveyed forward. Since the two sides are symmetrically arranged, the material can be effectively prevented from tilting during the conveying process. For example, when the material is disturbed by an external force on one side, the horizontal conveying assembly on the other side can provide an opposite force to balance and maintain stable conveying of the material. The clamping mechanism uses two clamping rollers 12. When the material needs to be clamped during the conveying process, the clamping rollers 12 act on the material. Compared with the traditional single clamping device, the two clamping rollers 12 can increase the contact area with the material, thereby reducing the friction generated during the conveying process after the material is clamped. Reducing friction can reduce energy loss and make the conveying smoother on the one hand, and reduce wear on the material on the other hand to ensure the surface quality of the material. In the transportation of some materials with high requirements on surface quality, this design can effectively avoid scratches or wear on the material surface.

[0023] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
