[0002] Laser tube cutting machines are specialized processing equipment that utilize lasers to cut tube materials. In recent years, with the continuous upgrade of laser tube cutting machine structures, the market has placed increasingly higher demands on tube cutting quality and efficiency. In terms of improving efficiency, the tube loading method is a key factor affecting processing efficiency. The loading device is an important piece of equipment that assists laser tube cutting machines in cutting tubes.

[0003] Traditional laser tube cutting machines rely on a combination of manual labor and overhead cranes for loading. This method is simple and unaffected by tube specifications and lengths. However, it has the following drawbacks: Site constraints necessitate the installation of overhead cranes and other lifting equipment; a low degree of automation and inefficient production; and safety issues during frequent tube lifting.

This method not only improves the automation level of factory production but also avoids the dangers of frequent pipe lifting. However, this method also has the following drawbacks: the automatic loaders are significantly affected by the specifications and length of the pipes; and the cost of automatic loaders is relatively high.

[0024] In this embodiment, the front section of the bed includes two first welding plates 4, the middle section of the bed includes at least one square tube 5, and the rear section of the bed includes two second welding plates 6. One ends of the two first welding plates 4 are respectively welded to both sides of the front end of the square tube 5, and one ends of the two second welding plates 6 are respectively welded to both sides of the rear end of the square tube 5. The upper end of the first support leg 3 is fixed between the two first welding plates 4, and a second support leg is fixed to each side end face of the square tube 5.

[0025] In this embodiment, the bottom of the first support leg 3 is fixedly connected to the mounting seat 7. The mounting seat 7 is a U-shaped bending structure, and the surfaces of the end plates on both sides are provided with long grooves. The side end surface of the bottom of the first support leg 3 is provided with a connecting hole, and the first support leg 3 and the mounting seat 7 are fixed by bolts passing through the connecting holes and the long grooves; the side end surfaces of the two second support legs are provided with connecting holes, and the two second support legs are installed in one mounting, and the second support legs are fixedly connected by bolts passing through the long grooves and the connecting holes.

[0026] In this embodiment, a threaded through hole is provided on the side wall of one end of the driven shaft 15, and a screw 16 is connected to the threaded through hole. One end of the screw 16 is fixedly inserted into the fixed plate. A long groove is provided on the rear section of at least one second welding plate 6. One end of the driven shaft 15 is movably inserted into the long groove, and the driven shaft 15 and the long groove are perpendicular to each other.

[0027] In this embodiment, two locking nuts are provided on the screw rod 16 , and the two locking nuts are respectively located on two sides of the fixing plate.

[0028] In this embodiment, a detection switch is provided at the rear section of the bed, and the detection switch is used to detect the position of the pipe material.

[0029] In this embodiment, a guide rail is provided between the upper end surface of the bed and the inner side surface of the chain 11 .

[0030] In this embodiment, the guide rail is made of nylon.

[0031] Specifically, the bed adopts a tube-to-sheet welding structure, which is welded as a whole and then finely processed; the mounting seat 7 and the support leg are matched with the side slots through fixing screws to adjust the overall height of the loading device so as to cooperate with the laser tube cutting machine to complete the loading action; the two second welding plates 6 are installed on the square tube 5, and the detection switch installed on the side of the second welding plate 6 is in a straight line with the center position of the two chucks of the laser tube cutting machine.

[0032] In the adjacent feeding mechanism, the transmission shafts 8 are connected by rigid couplings and fixed to the frame 1 component through bearings with square seats 10; the driving sprocket 13 is fixed to the transmission shaft 8 and driven to rotate by a flat key; the chain 11 is equipped with a partition 12; the nylon guide rail is fixed to the upper end surface of the bed to avoid dry friction between the chain 11 component and the frame 1 component, effectively protecting the chain 11 component;

[0033] The driven shaft 15 is connected to the driven sprocket 14 through a bearing to fix it on the bed; the driving sprocket 13 and the driven sprocket 14 are connected through a chain 11; the driven shaft 15 is connected to the fixed plate of the bed using a screw 16, and the position of the driven shaft 15 in the slot at the front end of the bed is adjusted by adjusting the length of the screw 16 to adjust the length of the chain 11 assembly while ensuring the tension of the chain 11.

[0034] The conveying mechanism 2 can be divided into a waiting area and a stacking area:

[0035] The waiting area is at the front end of the bed, and is divided into multiple workstations by the partition 12 on the chain 11. Multiple pipes can be placed during the feeding process to improve processing efficiency; the stacking area is at the tail end of the bed a, where bundles of pipes can be placed, and this position is higher than the conveying components, which protects the chain 11 components well and avoids interference with the feeding action.

[0036] Instructions for use: The reducer and motor 9 installed at one end of the frame 1 drive the entire transmission shaft 8 to rotate via the flat key installed on the transmission shaft 8; then the transmission shaft 8 drives the driving sprocket 13 to rotate via the flat key installed on the transmission shaft 8; then the driving sprocket 13 drives the chain 11 installed on the driving sprocket 13 and the driven sprocket 14 to rotate, thereby transporting the pipes separated by the partition 12 to the rear end of the frame 1;

[0037] Then, when the pipe is transported to the rear end of the frame 1, the detection switch detects that the feeding is in place, thereby controlling the stop of the feeding action; finally, the pipe passes through the floating support component on the laser pipe cutting machine and is sent to the center of the disk, completing the entire feeding action.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
