A square tube stacking mechanism 4 and a lifting and stacking mechanism are also connected to the base 1. The upper end of the inclined rod 51 corresponds to the conveying roller 2, and the lower end of the inclined rod 51 faces the side where the lifting and stacking mechanism is located. A transverse tube pushing structure 3 corresponding to the square tube stacking mechanism 4 is also provided on the base 1. A tube blocking and buffering structure 6 is provided at the lower end of the inclined rod 51.

[0024] A vertical rod 52 is connected to the lower part of the upper end of the inclined rod 51. The first driving mechanism 7 includes a guide sleeve 71 arranged on the base 1, and the middle part of the vertical rod 52 passes through the guide sleeve 71 and the two are slidably matched. The first driving mechanism 7 also includes a crank 73 and a connecting rod 72 that are hinged to each other, one end of the connecting rod 72 is hinged to the lower end of the vertical rod 52, and one end of the crank 73 is connected to a rotating shaft 74, and the rotating shaft 74 is linked to the first motor (not shown in the figure).

[0025] The pipe-blocking buffer structure 6 includes a fixed plate 62 fixedly connected to the diagonal rod 51, a guide rod 63 is slidably passed through the fixed plate 62, a buffer plate 61 and a stopper 64 are respectively provided at both ends of the guide rod 63, a spring 65 is provided between the buffer plate 61 and the fixed plate 62, and the buffer plate 61 faces the side where the upper end of the diagonal rod 51 is located.

[0026] The square tube stacking mechanism 4 includes a suspended rod 41, one end of which is connected to a slider 42, the slider 42 is slidably connected to a transverse guide rail 44, the transverse guide rail 44 is connected to the base 1, the transverse guide rail 44 is connected to a transverse driver 43, and the transverse driver 43 is connected to the slider 42. The push block 31 at the output end of the transverse tube pushing structure 3 and the suspended rod 41 are matched in height.

[0027] The pipe lifting and stacking mechanism includes a transverse support rod 8, and the transverse support rod 8 is connected to a first lifting mechanism 9. The first lifting mechanism 9 includes two annular chains 91 arranged in parallel, and the two ends of the transverse support rod 8 are connected between the two chains 91. The upper and lower sides of each chain 91 are respectively matched with an upper sprocket 92 and a lower sprocket 93, and the upper sprocket 92 and the lower sprocket 93 are both rotatably connected to the base 1.
