Snake roll calendering method and equipment

Abstract

The invention relates to a snake-rolling type calendaring method and device. The snake-rolling type calendaring method and device are characterized in that according to the snake-rolling type calendaring method, the surface of a plastic inner tube on which a middle layer is wound is extruded to an outer tube layer after being calendared in a spiral rubbing mode. In the snake-rolling type calendaring method, the surface of the plastic inner tube on which the middle layer is wound is extruded to the outer tube layer after being calendared in the spiral rubbing mode, wherein the spiral rubbing mode is that rubbing is conducted back and forth on the surface of the plastic inner tube on which the middle layer is wound in a manual simulating mode; and the material of the middle layer can be bonded to the surface of the plastic inner tube more tightly, so that it is guaranteed that the inner tube and the middle layer are not disengaged, the service life of a composite tube is prolonged, and the physical property of the composite tube is improved.

Description

technical field [0001] The invention relates to a snake-roll rolling method and equipment. Background technique [0002] The composite pipe is composed of multiple layers of material, which at least includes an inner pipe layer, a middle layer and an outer pipe layer. The inner pipe layer and the outer pipe layer are usually made of plastic materials, while the middle layer is a fiber cloth layer, etc., because the composite pipe has Good physical properties, the current composite pipe is widely used, but the current composite pipe is made of direct coating, so that the inner pipe, outer pipe layer and the middle layer are often separated, resulting in poor performance. Contents of the invention [0003] The object of the present invention is to provide a snake-rolling calendering method and equipment. The snake-rolling calendering method has a reasonable design and is conducive to making the prepared composite pipe not easy to delaminate. The snake-rolling calendering equ...
