The pull rod is fixed in the strip billet oven 8 and pulls the extrusion die 1; the pull rod is divided into a front part 2 and a rear part 3, the tail end of each section of the pull rod is provided with a wedge-shaped block 15, the wedge-shaped blocks 15 are clamped in wedge-shaped holes 14 of the limiting plate in turn to pull the die 1, and when one wedge-shaped block is wedged tightly, the other wedge-shaped block loosens the belt conveying mechanism to clamp a belt blank and conveys the belt blank to the direction of the extruder.
(2) The belt blank traction mechanism 7 is a traction mechanism with more than two rollers so as to increase the friction force of the belt blank on the roller and further to pull the belt blank out of the oven according to a set speed, and the belt blank is pulled to the front of the belt conveying mechanism 4 by the traction mechanism 7 and enters the drying tunnel. At the moment, the wedge block at the tail end of the front half part 2 of the pull rod is wedged in the limiting plate, and the wedge block at the tail end of the rear half part 3 of the pull rod pushes the limiting plate away through the oil cylinder to leave a gap.
(3) And when the belt is pulled, the belt feeding mechanism 4 at the rear end obtains a signal that the oil cylinder 12 is in place, and the clamping air cylinder 17 starts to act to clamp the belt blank.
(4) After the clamping signal is obtained, the belt feeding cylinder is actuated, the frame 16 is moved forward, and the belt blank is conveyed to a designated position in the direction of the extruder.
(5) The belt feeding mechanism 4 repeats the clamping and belt feeding actions until the belt feeding mechanism stops after the set action times, and meanwhile, the traction mechanism 7 stops acting;
