Background

The Krah pipe has the advantages of strong corrosion resistance, high ring stiffness, large production caliber, superior connection sealing performance and the like, and is widely applied to the fields of urban water supply, drainage, remote water delivery, farmland water conservancy and the like. Typically, the krah pipe is made by using high density polyethylene as a raw material to form a flat belt inner pipe, using a polypropylene corrugated pipe (PP corrugated pipe) as an auxiliary support for reinforcement, and adopting a hot winding forming process.

Therefore, the surface of the produced krah pipe has ripples formed by winding a polypropylene corrugated pipe, and during the cutting process of the krah pipe, once the cutting is performed at the positions of the wave crests and the slope parts of the ripples, the cuts are sunken or deformed, so that during the cutting process, the positions of the wave crests and the slope parts of the ripples need to be avoided, and the cutting position is positioned at the central position of the annular groove of the krah pipe.

In addition, the position of carat pipe is judged through utilizing photoelectric sensor to traditional cutting equipment, later utilize the anchor clamps that set up around the utilization to press from both sides tight location back to the carat pipe, cut again, but utilize photoelectric sensor to judge the cutting of carat pipe, because the size of photoelectric sensor facula, the reaction time of front and back anchor clamps all can exert an influence to the position accuracy of incision, so under general condition, the blade can not just in time aim at the centre of annular slot, in addition there are many other error factors, for example the shrink of carat pipe is inhomogeneous, and the reaction time difference that pneumatic system exists etc, so the probability that the knife tip is just aiming at the center of annular slot during cutting at every turn is very low, and can cause the condition that the carat pipe length that processes differs.

Although the above patent discloses that the cutting knife is automatically adjusted to be aligned with the center of the wave trough in the process of cutting the corrugated pipe by the arrangement of the guide plate and the wave trough on the spring matched corrugated pipe, the following problems still exist:

1. the length of the corrugated pipe processed by each positioning is different due to the deviation of the clamping time of the clamp and the reaction time of the pneumatic system;

2. the positioning of the cutter is firstly completed, the corrugated pipe is clamped and positioned, and in the clamping and positioning process, the corrugated pipe is subjected to secondary offset by the clamping force of the clamp, so that the positioning accuracy of the cutter is lost;

3. the baffle is at the in-process along with the cantilever rotation, when rotatory under the bellows, because of the self gravity of slider, can make the baffle lose the location to the bellows, consequently, when fixing a position the bellows at every turn, all need adjust the baffle and be located the bellows directly over, lead to the operation process loaded down with trivial details.
