All directional indications in the utility model (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] See also Figure 1-5 A semi-automatic feeding structure of a laser tube cutting machine includes a main structure 2, which is connected to a body 1 of the laser tube cutting machine. The main structure 2 includes a base frame 8, on which a plurality of synchronously running feeding mechanisms are arranged. A feeding baffle 3 is also arranged on one side of the base frame 8, which can block and align the tubes. The feeding mechanism includes a frame 9, which is connected to the base frame 8. A synchronously running chain feeding assembly 4 is arranged on the frame 9. A synchronously running feeding assembly 5 is also arranged on one side of the frame 9. The feeding assembly 5 includes a feeding arm 54, which is arranged on the frame 9. A tube transfer assembly 6 for conveying the tube into the laser cutting machine is also arranged on one side of the feeding arm 54.

[0023] A first driven sprocket 45 and a second driven sprocket 46 are arranged on both sides of the upper part of the frame 9, a driving sprocket 41 is arranged at the bottom of the frame 9, a transmission chain 42 is arranged on the first driven sprocket 45, the second driven sprocket 46 and the driving sprocket 41, and pipe stoppers 43 are arranged equidistantly on the transmission chain 42, so that the pipes can be sorted and loaded. A driving shaft 44 is arranged in the middle of the driving sprocket 41. Specifically, the driving shaft 44 is connected to multiple groups of driving gears in sequence, and the driving shaft 44 is connected to the output shaft of the conveying motor 7. The conveying motor 7 is arranged at the bottom of the frame 9. Through the conveying motor 7, the multiple groups of driving sprockets 41 can be synchronously driven to rotate, thereby completing the feeding function of the pipe.

[0024] First, place the pipe between the pipe blocks 43 on the transmission chain 42, and make one end of the pipe abut against the loading baffle 3. The loading baffle 3 aligns the pipe. At the same time, the pipes can be sorted and placed in sequence through the pipe blocks 43. The driving shaft 44 is driven to rotate by the conveying motor 7. The driving shaft 44 synchronously drives multiple sets of driving sprockets 41 to rotate. The driving sprocket 41 synchronously drives the first driven sprocket 45 and the second driven sprocket 46 to rotate through the transmission chain 42. As the transmission chain 42 moves, the transmission chain 42 drives the pipe block 43 to move. The movement of the pipe block 43 drives the pipe to move. The pipe is transported to the feeding assembly 5 through the pipe transfer assembly 6, and the pipe is transported to the laser cutting machine through the feeding assembly 5, and the pipe is cut by the laser cutting machine.

[0025] As a specific embodiment of this application, please refer to Figure 3-Figure 5 The pipe transfer assembly 6 includes an electric push rod 61, which is arranged on one side of the feeding arm 54. One end of the piston rod of the electric push rod 61 is connected to the mounting frame 63.

A lifting cylinder 64 is arranged in the mounting frame 63, and a transfer frame 62 is arranged at one end of the lifting cylinder 64, which can support the falling of the pipe.

[0026] When the pipe moves to the position of the transfer rack 62, the transfer rack 62 is lifted up by the lifting cylinder 64, and multiple groups of transfer racks 62 lift the pipe, and then the mounting rack 63 is driven by the electric push rod 61, and the mounting rack 63 drives the lifting cylinder 64 and the transfer rack 62 to move, and the transfer rack 62 drives the pipe to move. When the pipe moves to the position of the pipe blanking port 56, the lifting cylinder 64 contracts and drives the transfer rack 62 to move downward. The downward movement of the transfer rack 62 drives the pipe to move downward and places the pipe in the pipe blanking port 56. After the pipe blanking is completed, the electric push rod 61 drives the mounting rack 63 to reset and move to the initial position, and then the next pipe transfer is carried out.

[0027] As a specific embodiment of this application, please refer to Figure 3-Figure 5 A transmission rack 55 is arranged at the bottom of the feeding arm 54, and the transmission rack 55 is meshed with the transmission gear 53.

The transmission of the transmission gear 53 and the transmission rack 55 can drive the feeding arm 54 to move, thereby realizing the feeding function of the pipe. A pipe dropping port 56 is also arranged at one end of the feeding arm 54, which can position the pipe after feeding.

[0028] After the pipe is transported to the pipe drop outlet, when the laser pipe cutting machine gives a feeding signal, the feeding motor 51 drives the transmission shaft 52 to rotate, the transmission shaft 52 drives the transmission gear 53 to rotate, the transmission gear 53 drives the transmission rack 55 to move, the transmission rack 55 moves and drives the feeding arm 54 to move, the feeding arm 54 moves and drives the pipe to move, and feeds the pipe into the laser pipe cutting machine, and the laser pipe cutting machine cuts the pipe.
