Large diameter spiral pipe winding machine

Abstract

The invention discloses a large-caliber spiral pipe winding machine, comprising a machine frame, a feeding port, a guiding pressing mechanism, a pipe diameter limiting adjustment mechanism, a driving mechanism and a cutting mechanism, wherein the feeding port, the guiding pressing mechanism, the pipe diameter limiting adjustment mechanism, the driving mechanism and the cutting mechanism are arranged on the machine frame; the machine frame comprises a main panel; the feeding port is formed in the lower part of the main panel; the guiding pressing mechanism, the pipe diameter limiting adjustment mechanism and the cutting mechanism are arranged at the front side of the main panel; the driving mechanism is arranged at the rear side of the main panel; the pipe diameter limiting adjustment mechanism comprises a plurality of circular holes, a plurality of strip-shaped holes and a plurality of telescopic adjusting rod; the plurality of circular holes, the plurality of strip-shaped holes and the plurality of telescopic adjusting rods are uniformly arranged in a circular region of the main panel; the strip-shaped holes extend to a circle center in a radial direction of the circular region; the driving mechanism is connected with a guiding pressing roller and a limiting pressing roller; the cutting mechanism is arranged in the center of the circular region. The large-caliber spiral pipe winding machine disclosed by the invention has the advantages that the guiding pressing mechanism is not easily loosened and deformed by utilization of a pipe diameter adjustment mechanism, the out-of-roundness of a winding pipe is greatly reduced, the pipe diameter of the winding pipe is constant, and the pipe diameter can be quickly changed.

Description

technical field [0001] The invention relates to the field of large-diameter spiral pipe manufacturing equipment, in particular to a large-diameter spiral pipe winding machine. Background technique [0002] Chinese patent (Patent No. 02276483.6) discloses a multifunctional spiral tube winding machine. The winding machine is composed of several pairs of pressing rollers fixed or adjustable on the inner and outer sides of the circumference on the front of the working panel. The adjustable and fixed plastic profile guide block is guaranteed; the frame or work plate has a feeding mechanism composed of a pair of rollers. Working process: The upper and lower edges of the plastic profile with T-shaped ribs, grooves and protrusions are arranged through the feeding mechanism, glued by the gluing mechanism, enter the first pressing roller, and are guided by the guide block into the second and second. Three rollers... In this process, under the guidance of the roller guide ring, the p...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the guide block of the existing winding pipe is easy to deform and loosen, resulting in the increase of the out-of-roundness of the winding pipe and the inconsistency of the diameter of the pipe, as well as the extremely inconvenient, time-consuming and labor-intensive problems of the radially adjustable installation hole of the roller when changing the pipe diameter, this paper The invention provides a coated composite pipe delivery device
