Small-caliber plastic rib spiral tube without adhesive-bonded joint and production process for small-caliber plastic rib spiral tube without adhesive-bonded joint

Abstract

The invention discloses a small-caliber plastic rib spiral tube without an adhesive-bonded joint. The small-caliber plastic rib spiral tube comprises a plastic rib tube body, wherein the inner diameter of the plastic rib tube body is 6-16 mm; the inner wall of the plastic rib tube body is a smooth surface which is integrally molded; the outer wall of the plastic rib tube body is a smooth surface which is integrally molded; a spiral plastic rib which is wound on a tube body is arranged on the outer wall of the plastic rib tube body. A production process for the small-caliber plastic rib spiral tube without adhesive-bonded joint comprises the following steps: extruding a plastic rib tube material from an extrusion head, forming the plastic rib tube body in a plastic rib tube forming channel; after the spiral plastic rib material enters from a spiral material injection channel of a fixed sleeve, extruding the spiral plastic rib material from the spiral material extruding channel of a rotary sleeve and winding the spiral plastic rib material on the plastic rib tube body to form the plastic rib spiral tube without then adhesive-bonded joint. The plastic rib spiral tube is smooth in in-tube inner wall, and free of the adhesive-bonded joint, so that the product quality is greatly improved and relatively stable; the plastic rib spiral tube is free of the adhesive-bonded joints, so that the material conveying is relatively smooth and free of residues.

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 with a small diameter and no bonding seam 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.

AI Technical Summary

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 problems, the bonded joints are not firmly bonded, resulting in an increase in scrap rate and quality problems; On the material strip, and then through the spiral bonding of the rotating head, the pipe body needs a long-distance cooling water tank for the rotation of the pipe body caused by the rotation of the rotating head. For example, if it is necessary to produce a fixed length of 50m Long hose, i.e. 50m long cooling water tank required

Traditional technology and production equipment cannot produce hoses with an inner diameter of 16mm due to the limitation of the screw head
