Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 6The present embodiment discloses a pipe cutting device, including a loading rack 100, the loading rack 100 includes a horizontal section 110 and an inclination, the inclination section 120 is inclined downward, a limiting mechanism 200 is arranged on one side of the inclination section 120, a conveying mechanism 300 is arranged on the other side of the limiting mechanism 200, a cutting mechanism 400 is arranged at the end of the conveying direction of the conveying mechanism 300, the conveying mechanism 300 includes a support platform, the support platform is lower than the limiting mechanism 200, the support platform is provided with a plurality of conveying rollers 320, the highest point of the conveying rollers 320 is in contact with the limiting mechanism 20 0 is flush with the lowest point of the upper surface of the limiting mechanism 200, the highest point of the upper surface of the limiting mechanism 200 is not higher than the lowest point of the inclined section 120, the conveying roller 320 includes a first roller body 321 and a second roller body 322, the diameters of the first roller body 321 and the second roller body 322 are gradually reduced from the end away from each other to the end close to each other so that the conveying roller 320 forms an hourglass structure, and the limiting mechanism 200 includes a box body, and a first limiting plate 500 and a second limiting plate 600 that can be raised and lowered are arranged in the box body, and the first limiting plate 500 and the second limiting plate 600 are alternately raised and lowered. The pipe is placed on the loading rack 100, and can slide to the limiting mechanism 200 through the inclined section 120, and the amount of pipe movement can be limited by the limiting mechanism 200. The limiting mechanism 200 includes a first limiting plate 500 and a second limiting plate 600. The first limiting plate 500 is close to the conveying device, and the second limiting plate 600 is close to the loading rack 100. The first limiting plate 500 and the second limiting plate 600 are alternately raised and lowered, and the distance between the first limiting plate 500 and the second limiting plate 600 can only accommodate one pipe. When the first limiting plate 500 is raised and the second limiting plate 600 is lowered, the pipe moves from the loading rack 100 to between the first limiting plate 500 and the second limiting plate 600; when the second limiting plate 600 is raised and the first limiting plate 500 is lowered, the pipe located between the first limiting plate 500 and the second limiting plate 600 moves to the conveying mechanism 300. Such a cycle ensures that the pipes can only pass through the limiting mechanism 200 one by one and enter the telescopic mechanism, thereby ensuring the stability of transportation.

The second plate body 722 partially covers the support rod. A buffer brush 723 is provided on the side of the second plate body 722 facing the support rod. At the same time, the thickness of the second plate body 722 increases continuously from bottom to top. The movement of the first support plate 510 or the second support plate 610 can drive the movement of the second guide member 512. When the second guide member 512 moves, it will contact and rub against the buffer brush 723, thereby buffering the movement of the second guide member 512.

[0025] A driving assembly for driving the first support plate 510 and the second support plate 610 to rise and fall is arranged in the installation cavity 210, and the driving assembly includes a motor 220, and the output section of the motor 220 is provided with a first gear 221.
