[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0024] In the description of this application, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] Please refer to a fully automatic side-mounted laser tube cutting machine with feeding mechanism. Figures 1-6 The system includes a pipe cutting machine 1 for cutting pipes and a feeding rack 2 fixed on the pipe cutting machine 1. The pipe cutting machine 1 is a cutting processing machine tool, specifically a side-mounted laser pipe cutting machine, the model and size of which are not limited, and it is usually used to cut pipes of different shapes. The feeding rack 2 is connected to the machine bed of the pipe cutting machine 1 to ensure the stability of both during operation. The feeding rack 2 has three feeding components 200. The number of feeding components 200 is not limited to this embodiment. The number of feeding components 200 and the spacing between them can be changed according to the model and size of the pipe cutting machine 1 to adapt to the corresponding pipe cutting machine 1 for automatic feeding. The feeding rack 2 simultaneously carries the pipes and feeds them to the pipe cutting machine 1 through multiple feeding components 200. Multiple feeding components 200 simultaneously support long strip-shaped pipes to achieve stable feeding of the pipes.

[0027] Furthermore, the feeding assembly 200 is provided with a tensioning mechanism 210 and a feeding inclined column 220 that docks with the tensioning mechanism 210. The feeding assembly 200 has a frame structure for supporting and connecting the bed of the pipe cutting machine 1. The tensioning mechanism 210 and the feeding inclined column 220 are both fixed to the frame. The tensioning mechanism 210 conveys the pipe upward and into the top of the feeding inclined column 220. The feeding inclined column 220 can be a plate structure or a column structure. Its structure is not limited to this embodiment. The inclined feeding inclined column 220 allows the pipe at the top to slide down to its bottom to be fed towards the pipe cutting machine 1. The tensioning mechanism 210 is equipped with a tensioning belt 211 that can carry and transport pipes and multiple roller mechanisms 222 connected to the tensioning belt 211. A transmission rod 205 is connected between the roller mechanisms 222 at corresponding positions on the multiple feeding components 200. The middle feeding component 200 is equipped with a tensioning motor 204 connected to the transmission rod 205. The tensioning motor 204 is connected to the transmission rod 205 through a transmission chain. The corresponding roller mechanisms 222 of the three feeding components 200 can rotate simultaneously through the connection of the transmission rod 205. The tensioning motor 204 drives the tensioning belt 211 to tighten or loosen. When the tensioning belt 211 tightens, it will drive the pipe placed on it to move upward. Due to the fixed method of the tensioning belt 211 being higher at the rear and lower at the front, the pipe will move towards the upward feeding inclined column 220 after moving upward, thereby reaching the upward feeding inclined column 220.

[0028] Furthermore, the feeding assembly 200 is equipped with a first baffle assembly 230 that can move up and down. The first baffle assembly 230 can prevent the pipes on the feeding inclined column 220 from sliding down by moving upward. The first baffle assembly 230 is connected to a pusher cylinder 201. The first baffle assembly 230 can move back and forth with the pusher cylinder 201 to push the excess pipes on the feeding inclined column 220 back to the tensioning mechanism 210. The tensioning mechanism 210 sends one or more pipes to the top of the feeding inclined column 220. At this time, the baffle assembly 230 moves upward to prevent the pipes from sliding down. Then the pusher cylinder 201 pushes the first baffle assembly 230 backward to push the excess pipes back to the tensioning mechanism 210. When there is only one pipe left on the feeding inclined column 220, the first baffle assembly 230 retracts downward, and the pipe can slide down smoothly for feeding.

[0029] Furthermore, the feeding assembly 200 is provided with a mounting plate 202, which is fixed to the frame of the feeding assembly 200. The first baffle assembly 230 includes a fixed plate 231 connected to the mounting plate 202 via a slide rail structure, a first cylinder 232 obliquely disposed on the fixed plate 231, and a first baffle plate 233 connected to the first cylinder 232. A slide rail structure is provided between the first baffle plate 233 and the fixed plate 231. The pushing cylinder 201 is connected to the fixed plate 231. The first cylinder 232 is angled to match the structure of the feeding inclined column 220. Therefore, the slide rail structure between the fixed plate 231 and the mounting plate 202 is also angled. The slide rail structure includes a slide rail and a slider. The direction of the slide rail structure determines the moving direction of the fixed plate 231 or the first baffle plate 233. The pushing cylinder 201 can push the first baffle assembly 230 to move obliquely forward and backward, while the first cylinder 232 pushes the first baffle plate 233 to move obliquely up and down. The first baffle plate 233 is equipped with a pushing assembly, which includes a third cylinder 234 and a push plate 235 connected to the third cylinder 234. In addition to pushing away excess pipe on the feeding inclined column 220 through the first baffle plate 233, the third cylinder 234 can push the push plate 235 to further push the pipe, providing an additional pushing distance beyond the stroke of the pushing cylinder 201. This provides greater flexibility to meet the feeding needs of pipes of different specifications and has wider applicability.

[0030] Furthermore, the mounting plate 202 is provided with a limiting screw 240 that can limit the movement distance of the first material blocking component 230. The limiting screw 240 is mounted on the mounting plate 202 through a threaded block that cooperates with it. When the first material blocking component 230 is pushed by the pushing cylinder 201, since the stroke of the pushing cylinder 201 is fixed, the distance of the first material blocking component 230 moving back and forth can be changed by the limiting screw 240 pressing against the fixing plate 231. By rotating, the limiting screw 240 can be moved back and forth to set the distance of the first material blocking component 230 moving back and forth, ensuring that even when feeding pipes of different diameters, the pushing can be performed by adjusting the stroke, so that after the pushing, only one pipe remains on the feeding inclined column 220.

[0031] Furthermore, a second baffle assembly 250 is provided on the side of the middle part of the feeding inclined column 220 on the feeding assembly 200. The second baffle assembly 250 includes a second baffle plate 251 and a second cylinder 252 connected to the second baffle plate 251. The second baffle plate 251 is fixed by a rotating shaft structure, and one end is connected to the second cylinder 252. When the second cylinder 252 extends, the second baffle plate 251 flips and protrudes above the surface of the feeding inclined column 220, which can prevent the pipe from sliding down. When the second cylinder 252 retracts, the second baffle plate 251 flips downward, and the pipe can continue to slide down. The feeding assembly 200 is located near the pipe cutter on the feeding inclined column 220. A third baffle plate 203 is provided on one side of the pipe cutter 1. The third baffle plate 203 has an "L" shaped structure. The pipe stops when it slides down to the third baffle plate 203. The position of the third baffle plate 203 corresponds to the lifting mechanism of the pipe cutter 1. The pipe completes the loading process of the loading rack 2 when it reaches the third baffle plate 203. The second baffle assembly 250 serves as a buffer structure for the pipe sliding down to prevent excessive impact when the pipe slides directly from the top of the loading inclined column 220 to the bottom, which could cause pipe deformation or equipment damage. The second baffle plate 251 and the third baffle plate 203 are also provided with a buffer pad on the side away from the pipe cutter 1 to provide a buffering effect when the pipe comes into contact with the machine.

[0032] Furthermore, the pipe cutting machine 1 is equipped with multiple material support components 101 for lifting the pipes delivered from the loading rack 2. Each material support component 101 typically includes a lifting cylinder and a variable diameter wheel. The pipe cutting machine 1 is equipped with a rear clamping component 102 and a front clamping component 103 for clamping the pipes for processing. The pipe cutting machine 1 is also equipped with a cutting head 105 for cutting the pipes; the cutting head 105 is a laser cutting head. The rear clamping component 102 and the front clamping component 103 typically have cylinders or motors for movement. The rear clamping component 102, the front clamping component 103, the material support component 101, and the cutting head 105 are existing technologies and will not be described in detail. A variable diameter wheel front receiving rack 110 is located on the side of the pipe cutting machine 1 away from the rear clamping component 102. The variable diameter wheel front receiving rack 110 includes a lifting cylinder and a variable diameter wheel front receiving rack. The cylinder is lowered and the top is a variable diameter wheel; after the two loading racks load the pipes, the lifting assembly 101 lifts the pipes up and clamps them forward through the rear clamping assembly 102 to complete the entire automatic loading process. The front clamping assembly 103 can move back and forth. When the rear clamping assembly 102 approaches the front clamping assembly 103 with a certain distance remaining, the front clamping assembly 103 moves forward to avoid it. The closer the rear clamping assembly 102 is to the cutting head 105, the shorter the tail of the pipe. When it is necessary to cut a long pipe, because the clamping part of the long pipe is too far away from the front clamping assembly 103, the pipe will sway left and right and up and down, which seriously affects the cutting accuracy. This is where the variable diameter wheel front receiving rack 110 is needed to support the bottom of the pipe and limit the left and right movement of the pipe, effectively improving the cutting accuracy when cutting long pipes.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
