The driving motor drives the driving shaft 210 to rotate through the chain belt, and the lifting platform 205 is lifted up and down through the forward and reverse rotation of the driving shaft 210 . The pipe placed on the incline support 213 naturally rolls into the upper part of the lifting frame 208 by gravity. When the pipe rolls into the top of the lifting frame 208, its gravity changes, so that the gravity sensor generates a signal to identify and judge that the upper part is carrying a pipe. to the specified location. After the pipe rolls from the lifting frame 208 to the upper pipe frame 202, its gravity changes, so that the gravity sensor generates a signal to identify and judge that there is no pipe on the top. At this time, the lifting frame 208 starts to descend.

The pipe naturally rolls from the upper pipe rack 202 to the opening between the first clip 303 and the second clip 304 by its own gravity. Since the distance between the first clip 303 and the second clip 304 extends to the outer end of the feeding tray 302, a single pipe can be clamped (adjusted according to the specific diameter of the pipe).

At this time, the conveying motor 40 is moved 2 Drive the moving screw 403 to rotate and drive the moving conveying frame 401 to move, thereby adjusting the position of the carrying conveying trough 408, and place the pipes in the grooves 409 on the carrying conveying trough 408 in sequence. After the grooves 409 are filled, the mobile conveying frame 401 moves to the bottom of the conveying wheel 411 as a whole.

During the state where the pipe is placed in the state of the conveyor wheel 411, the transmission wheel 416 and the linkage wheel 417 are in a relatively open state, providing the corresponding activity space for the lift -type motion of the pipe. After the installation is completed, the pressure wheel drives 414 to promote the downward movement of the voltage board 413, which makes the upper end of the transmission wheel 416 against the pipe. The rotation tube of the transmission wheel 416 starts to be transported on the conveyor wheel 411. The pipe is delivered from one end of the pinch roller delivery frame 412 .
