[0002] Chuck-type laser tube cutting machines are generally equipped with a feeding rack and a feeding follow-up support mechanism to assist in the feeding of tubes and to provide follow-up support for the tubes during processing. Regarding the three-chuck laser tube cutting machine disclosed in application number 202411957671.7, its feeding assembly is driven by a feeding rotation drive device located on the operating side, which rotates the feeding transmission shaft, thereby driving the feeding conveyor chain. However, because multiple feeding assemblies are arranged parallel to each other on the left and right, and multiple feeding rotation drive devices and multiple feeding transmission shafts are used to achieve synchronous linkage of multiple feeding assemblies, the gaps between the multiple spaced feeding assemblies cannot be utilized. The tubes can only be fed by gantry crane, resulting in a single feeding method and significant limitations.

Detailed Implementation

[0020] This utility model provides a feeding rack. 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.

[0021] Please refer to Figures 1 and 3. This utility model provides a feeding rack, including multiple feeding assemblies arranged at intervals and parallel to each other. Each feeding assembly includes a feeding rack 1, a feeding drive wheel 21 and a feeding driven wheel 22 rotatably mounted on the feeding rack 1, and a feeding chain 23 wound around the feeding drive wheel 21 and the feeding driven wheel 22. Multiple feeding limit blocks 24 are provided on the outer surface of the feeding chain 23, and a feeding storage slot is formed between two adjacent feeding limit blocks 24. The feeding drive wheels 21 on the multiple feeding assemblies are connected by a feeding transmission shaft 31, which is connected to a feeding drive mechanism 4. The feeding drive mechanism 4 is located downstream of the feeding rack 1. The multiple feeding transmission shafts 31 are connected by a coupling 32 and are all located downstream of the feeding rack 1. The lower surface of the downstream of the feeding rack 1 is fixedly connected to the upper surface of the mounting side seat 10 of the bed.

[0022] In practical applications, the bed is located downstream of the loading rack, and a loading follow-up support mechanism 20 is installed on the mounting side seat 10. Multiple feeding components are used to support and transport the pipes, which are confined within the feeding and storage bays to prevent displacement. Since a loading space is formed between the feeding components, the pipes can be delivered to this space via forklift. The loading operation can be completed with simple manual assistance; the operator manually places the pipes from the forklift into the upstream feeding and storage bay, or a lifting method can be used, providing users with diverse loading methods. Under the action of the feeding drive mechanism 4, the rotation of the feeding chain 23 drives the pipes downstream. After the pipes move downstream, the loading follow-up support mechanism 20 lifts the pipes to be coaxial with the chuck, facilitating cutting by the chuck. As the feeding drive mechanism 4 continues to operate, continuous pipe feeding can be achieved.

[0023] The downstream of the feed rack 1 is fixed to the upper surface of the mounting side seat 10. Compared with the existing feed rack, which is fixed to the side wall of the bed, the feed rack 1 is closer to the feeding follow-up support mechanism 20, which is also mounted on the mounting side seat 10.

[0024] The aforementioned loading rack, by placing the feeding drive mechanism 4 downstream, adapts the feeding transmission shaft 31 downstream, freeing up space upstream and providing loading space for forklifts to pass through, thereby providing users with diverse loading methods and improving the applicability of the loading rack.

[0025] Referring to Figures 1 and 3, in some embodiments, the feeding frame 1 includes two side plates 11 arranged parallel to and symmetrically arranged to the left and right of the pipe conveying direction, a vertical beam 13 fixedly connected to the lower surface of the upper part of the two side plates 11, and an upper connecting plate 12 fixedly connected to the upper surface of the two side plates 11; the upper and lower ends of the two side plates 11 are respectively provided with slots, and the feeding drive wheel 21 and the feeding driven wheel 22 are rotatably disposed in the corresponding slots; multiple vertical beams 13 are detachably connected by a feeding connecting rod 5. The side plates 11, the upper connecting plate 12 and the vertical beams 13 can be fixedly connected by welding, and the outer surface of each side plate 11 is provided with a bearing seat, so that the feeding drive shaft 31 can rotate relative to the feeding frame 1.

[0026] Referring to Figures 1 and 2, in some embodiments, the feeding drive mechanism 4 includes a feeding motor mounting plate 41 disposed on the side wall of the mounting seat 10, a feeding drive motor 42 disposed on the feeding motor mounting plate 41, a feeding drive sprocket 43 disposed on the output end of the feeding drive motor 42, a feeding driven sprocket 44 sleeved on the feeding transmission shaft 31, and a feeding drive chain 45 wound between the feeding drive sprocket 43 and the feeding driven sprocket 44. When it is necessary to transport pipes, the output end of the feeding drive motor 42 rotates, driving the feeding drive sprocket 43 to rotate. Under the transmission of the feeding drive chain 45 and the feeding driven sprocket 44, the feeding transmission shaft 31 is driven to rotate, which in turn drives the feeding drive wheel 21 on the feeding transmission shaft 31 to rotate, providing power to the feeding chain 23.

[0027] Referring to Figure 2, in some embodiments, the feeding motor mounting plate 41 is provided with a waist-shaped hole 411 extending along its height direction, and the mounting side seat 10 is provided with a first threaded hole. A fixing screw (not shown in the figure) is provided in the waist-shaped hole 411 and the first threaded hole. An adjusting block 46 is also provided on the side wall of the mounting side seat 10. The adjusting block 46 is located below the feeding motor mounting plate 41. The bottom of the feeding motor mounting plate 41 is provided with a first threaded hole. A tightening screw 461 extending in the vertical direction is threadedly connected to the middle of the adjusting block 46. Two tightening screws 462 extending in the vertical direction pass through the adjusting block 46. The tightening screw 461 is located between the two tightening screws 462. The lower surface of the feeding motor mounting plate 41 is provided with a tightening threaded hole that mates with the tightening screw 462. The tightening screw 461 is used to press against the lower surface of the feeding motor mounting plate 41.

[0028] Under normal conditions, when the top screw 461 is tightened, the head of the tightening screw 462 is close to the bottom surface of the adjusting block 46. The position change of the feeding motor mounting plate 41 corresponds to the position change of the feeding drive motor 42. When adjusting the position of the feeding motor mounting plate 41 on the mounting side seat 10, first loosen the fixing screw, then loosen the top screw 461, and reduce / increase the tightening amount of the tightening screw 462. The tightening screw 462 guides the movement of the feeding motor mounting plate 41, thereby controlling the position of the feeding drive motor 42 on the feeding motor mounting plate 41. Then tighten the top screw 461 so that the top screw 461 can hold the feeding motor mounting plate 41, and the head of the tightening screw 462 is close to the bottom surface of the adjusting block 46 again, effectively preventing the tightening screw 462 from loosening and providing initial positioning for the feeding motor mounting plate 41. The workpiece operator can apply force to adjust the position by turning the tightening screw 462 and the top screw 461 with a hex screwdriver. After adjusting the position of the feeding motor mounting plate 41, the fixing screw is locked to complete the adjustment of the feeding motor mounting plate 41. The adjustment operation is simple and precise.

[0029] Referring to Figure 3, in some embodiments, the feeding drive mechanism 4 is provided with a feeding protective cover 6. The feeding protective cover 6 ensures that all transmission components are located within it, preventing debris from falling in, thus improving the service life of the feeding drive mechanism 4 and reducing the frequency of maintenance.

[0030] Referring to Figure 3, in some embodiments, the feeding protective cover 6 includes a motor cover 61 and a transmission cover 62 communicating with the inner cavity of the motor cover 61; the feeding motor mounting plate 41 and the feeding motor are both disposed inside the motor cover 61; the feeding drive sprocket 43, the feeding driven sprocket 44, and the feeding drive chain 45 are all disposed inside the transmission cover 62; the side wall of the mounting side seat 10 is also provided with a bracket 63, the top of the bracket 63 being fixedly connected to the bottom of the transmission cover 62; one end of the transmission cover 62 is provided with a clearance hole for the feeding drive shaft 31 to pass through; the other end of the transmission cover 62 is fixedly connected to the side wall of the motor cover 61, and the side wall of the transmission cover 62 is fixedly connected to the side plate 11. The feeding protective cover 6 is divided into two main parts. On the one hand, this facilitates the preparation of sheet metal parts and reduces manufacturing difficulty. On the other hand, it makes the shape of the feeding protective cover 6 more compatible with the shape of the feeding drive mechanism 4, reducing the space occupied by the feeding drive mechanism 4. In addition, the motor cover 61 is located below the feeding frame 1, further reducing the space occupied by the feeding drive mechanism 4. The bracket 63 is set to improve the connection stability of the transmission cover 62 and prevent the bracket 63 from touching components such as the feeding drive wheel 21 or the feeding drive shaft 31.

[0031] Referring to Figure 3, in some embodiments, an end cap 14 is provided upstream of the two side plates 11. The end cap 14 is used to cover the feeding driven wheel 22. The feeding driven wheel 22 is located upstream (i.e., on the operating side). By providing the end cap 14, the feeding driven wheel 22 is prevented from getting caught in clothing or other items during rotation, thereby improving the safety performance of the feeding rack.

[0032] Referring to Figure 3, in some embodiments, limit plates 15 are provided on both the upstream and downstream side walls of the side plate 11. When the pipe is conveyed downstream and in place, due to the pipe's continued inertia in the downstream direction, the limit plate 15 is provided at the downstream position to prevent the pipe from slipping off the feeding rack 1, thereby improving the safety of the feeding rack. The upstream limit plate 15 can protect the feeding driven wheel 22.
