Embodiment 1

[0097] The base tube is made of ultra-high molecular weight polyethylene, the outer diameter is D=104mm, the inner diameter is 96mm, the selected composite belt has a bandwidth of L=200mm (the belt thickness is 0.6mm), and the composite belt is made of polyethylene.

[0098] The winding method is as follows:

[0099] In the first step, the winding angle α=54.63° is determined according to the outer diameter D of the base tube and the width L of the reinforcing belt; accordingly, the taper angle of the tapered belt roller is selected as 35.37°.

[0100] The second step is to start the front and rear two speed-regulating motors, and turn on the reinforcing tape winding machine. At the same time, according to the material of the substrate tube, choose to turn on the annular flame spray device or the first hot air blowing device, and follow the In the order that the big gear is in the front and the big gear on the side far from the extruder is in the order, first manually pull the free e...

Embodiment 2

[0112] The base tube is made of polypropylene, the outer diameter is D=308mm, the inner diameter is 298mm, and the standard reinforced belt with a bandwidth of L=300mm (the belt thickness is 0.8mm) is selected. The composite belt is made of polypropylene, and the number of simultaneous windings of each layer of composite belt is N = 2;

[0113] The first step is to determine the winding angle α=52.68° according to the outer diameter D of the base tube and the width L of the reinforcement belt; accordingly, the cone angle of the tapered belt roller is selected as 37.32°;

[0114] Among them, the base tube is heated by flame jet, and the outer flame temperature of the flame is 800-900°C until the surface of the base tube reaches a viscous flow state; the hot air outlet temperature of the second hot air blowing device is 400-500°C until the surface of the composite belt reaches a viscous flow state.

[0115] The rest are the same as in Example 1.

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 plastic pipe and a winding method thereof. Background technique [0002] In the production process of fully bonded 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 is: the stable control of the tension of the composite tape, the winding balance angle, the control of the fusion temperature, time, pressure and other key process parameters between the composite tape and the base tube (tube stock), In order to ensure the quality of the fusion between the two, this is also the key technical point and difficulty in the production process of the fully combined reinforced thermoplastic pipe. [0003] In the prior art, the re...
