The invention belongs to a moulding wheel for producing a zigzag drip irrigation tape. The moulding wheel for producing the zigzag drip irrigation tape comprises a shaft, a vacuum part, a cooling part and a drip irrigation tape moulding part, wherein the drip irrigation tape moulding part is arranged on outer circumference surface of the moulding wheel and is divided into three regions, namely a zigzag labyrinth channel moulding region, a bonding region and a bubble transition region; the zigzag labyrinth channel moulding region comprises multiple negative pressure moulding grooves which are continuously arranged along the circumference direction of the moulding wheel and are same in shape, each negative pressure moulding groove is composed of a zigzag negative pressure moulding groove, a water inlet negative pressure moulding groove and a water outlet negative pressure moulding groove, the water inlet negative pressure moulding grooves communicate a bubble region with a zigzag channel negative pressure moulding groove, the water outlet negative pressure moulding groove is communicated with the other end of the zigzag channel negative pressure moulding groove, and the zigzag channel negative pressure moulding groove is a negative pressure moulding groove between two columns of zigzag bumps which are opposite in prong and arranged in a staggered manner. By adopting the drip irrigation moulding wheel, a zigzag drip irrigation tape with excellent hydraulic performance such as flow uniformity and anti-clogging performance can be produced, the production speed is relatively high, and the cost is relatively low.
