[0022] In this utility model, the transmission mechanism includes a second motor 16 installed in the second mounting box 6 and a cylinder 15 installed on the top of the inner wall of the first cavity.

[0023] Working principle: When using this utility model, the pipe is first placed on the placement platform 9 and the first placement roller 11, and then pushed onto the second placement roller 20. Next, the first motor 10 and the cylinder 15 are turned on. The first motor 10 drives the bidirectional lead screw 12 to rotate. The bidirectional lead screw 12 drives the two clamping rollers 14 to move inward through the moving block 13 and the first mounting seat 17 to clamp the pipe. The cylinder 15 drives the second mounting seat 18 and the pressure roller 19 to move downward and abut against the pipe. At this time, the second motor 16 and the third motor 22 are turned on. The second motor 16 drives the second placement roller 20 to rotate, and the friction is increased by the rubber ring 21. The force propels the pipe forward. When the pipe reaches the cutting mechanism, the third motor 22 drives the drive gear 23 to rotate, which in turn drives the driven wheel group 24 to rotate, which in turn drives the outer gear ring 25 to rotate. When the outer gear ring 25 rotates, the blade 26 also rotates. The limit rod 27 is movably connected to the slide, so when the outer gear ring 25 rotates, the relative rotation of the blade 26 is a limit rotation, thereby completing the inward rotation and convergence of the blade 26, and thus completing the cutting of the pipe. After the pipe is cut, it is pushed forward and falls into the material box 3 through the discharge port via the guide table 29. After the cutting is completed, the device is reset and the power is turned off.
