Plastic rib spiral pipe without adhesive-bonded joints and manufacturing technique thereof

Abstract

The invention discloses a plastic rib spiral pipe without adhesive-bonded joints and manufacturing technique thereof. The plastic rib spiral pipe without the adhesive-bonded joints and the manufacturing technique thereof comprise a plastic rib spiral pipe body, the inner wall of the plastic rib spiral pipe body is a one-piece smooth surface, the outer wall of the plastic rib spiral pipe body is a one-piece smooth surface, and spiral plastic ribs wind around the outer wall of the plastic rib spiral pipe. The manufacturing technique of the plastic rib spiral pipe without the adhesive-bonded joints comprises the steps that plastic rib pipe materials are extruded from the head of an extruder, and the plastic rib pipe body is formed in a plastic rib pipe forming channel; meanwhile, spiral plastic rib materials enter a spiral plastic rib material injection channel of a fixed sleeve, then the spiral plastic rib materials are extruded from a spiral-shaped material extruding channel of a spiral sleeve and wind around the plastic rib pipe body, and the plastic rib spiral pipe without the adhesive-bonded joints is formed. The plastic rib spiral pipe without the adhesive-bonded joints and the manufacturing technique thereof have the advantages that the inner wall of the plastic rib spiral pipe is smooth and no adhesive-bonded joints exist, so that the product quality is greatly improved and the stability is achieved; due to the fact that no adhesive-bonded joints exist on the plastic rib spiral pipe, the conveying of the materials are more smooth and no residues exist.

Description

technical field [0001] The invention relates to the technical field of plastic-reinforced pipe production equipment, in particular to a plastic-reinforced spiral pipe without adhesive joints and a production process thereof. Background technique [0002] The plastic-reinforced tube is made of high-quality synthetic materials embedded with a hard plastic-reinforced spiral skeleton. The inner and outer walls are smooth and the bending radius is small. It has good negative pressure resistance. Anti-aging properties. The plastic-reinforced pipe is an ideal pipe for vacuum suction of powder and particles in factories, agriculture and water conservancy projects, and for conveying water and oil. It is an excellent substitute for rubber tubes and metal tubes.

Problems solved by technology

The production process of the plastic rib hose in the prior art is to extrude the ribs and material strips first, and then bond and form them on the rotating head, which will cause the small-diameter pipes to be unable to be produced due to the size of the rotating head; at the same time, due to the traditional process Extrude the ribs and material strips first and then bond them. Due to temperature coordination problems and raw material p
