Abstract

The invention discloses a whole combination type enhanced thermoplastic pipe composite tape winder and a winding method thereof. In the provided composite tape winder, the functions of composite tape delivering, tension force controlling, and winding angle controlling are integrated into a big gear; during the winding process among a matrix pipe straightening device, a matrix pipe preheating device, and a composite tape, the heating or preheating device of the contact surface between the matrix pipe and composite tape is connected to the large gear so as to drive the devices synchronously, thus during the operation process, the synchronism among rotation parts, stability, and uniformity are greatly improved; moreover, the mechanical structure of the winder is simplified, the complicated electric-control device is saved, and the fault rate during the operation process and maintenance cost are both reduced therefore. The provided wing method of the composite tape winder has the advantages of good continuity and stability, high automation degree, and good quality of composite tape winding, and thus has a good market promotion and application prospect.

Description

technical field [0001] The invention relates to a reinforcing tape winding machine and a reinforcing tape winding method thereof, in particular to a composite tape winding machine of a fully combined reinforced thermoplastic pipe and a winding method thereof. Background technique [0002] In the production process of fully integrated reinforced thermoplastic pipes, the winding quality of the composite tape is the key to the quality of the final product. Among them, the key to the winding quality control of the composite tape lies in: the tension of the composite tape, the stable control of the winding balance angle, the control of key process parameters such as the fusion temperature, time, and pressure between the composite tape and the base tube (tube blank), In order to ensure the fusion quality between the two, this is also the technical key point and difficulty in the production process of the fully integrated reinforced thermoplastic pipe. [0003] In the prior art, r...
