Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of winding of composite pipes, in particular to a full-automatic reinforcing winding machine for composite pipes. BACKGROUND

[0002] High-pressure conveying pipes are mostly composite pipes made of polymer materials. In order to enhance the strength of the composite pipe, the prior art usually pre-tightly winds a layer of winding tape or winding wire on the outer wall of the composite pipe. After winding, adhesion is achieved by baking or weaving the winding.

[0003] The existing winding method mostly utilizes the relative rotation of the winding machine and the composite pipe. By installing the winding tape or winding wire on the winding machine, the winding wire is wrapped around the composite pipe at an inclined angle in a circumferential array. The composite pipe is rotated in the opposite direction and is pushed horizontally, thereby completing the winding.

[0004] The compactness and winding strength of the winding wire are related to the angle of inclination. For pipes of different outer diameters, the angle of winding needs to be adjusted slightly. The stability during rotational winding also affects the compactness of the winding. However, during actual winding, due to the traction of the rotating winding wire and the pulling of the counter-rotating composite pipe, the rotation of the winding disc is easily offset. The vibration generated during rotation driving also causes the winding wires to loosen. SUMMARY

Through the cooperation of the first spring 31 and the first screw ring 29, the position of the primary adjustment is maintained. At this time, the second screw ring 30 is rotated to achieve the purpose of advancing the top rod 33 horizontally, so that the end plate 37 extrudes the second spring 35, increases the pressure of the second spring 35 on the limiting frame 27, and further increases the fitting pressure between the rotating ball 28 and the rolling ball 18.
