Embodiment 1

[0040] A thermoplastic fiber winding pipe equipment, comprising: an unwinding device 1, a first infrared heater preheating device 2, a second infrared heater preheating device 2', an infrared thermometer 3, a core mold infrared heater 4, a core Die 5, pneumatic pressure roller 6, frame 7, trolley 8, horizontal rotating shaft 9, tension meter 10, first guide roller 11, second guiding roller 11', bearing plate 13, supporting ball 14, of which the horizontal rotating shaft 9 It is made up of rotating shaft 15, key 16, thrust bearing 17, bearing seat 18, gear 19.

[0041] The frame 7 is the bearing part of the thermoplastic fiber winding pipe equipment, and is mainly used for installing the trolley 8, the mandrel 5, the unwinding device 1, the first infrared heater preheating device 2, and the second infrared heater preheating device 2' , mandrel infrared heater 4, infrared thermometer 3, tensiometer 10, pneumatic pressure roller 6, horizontal rotating shaft 9 and first guide roll...

Embodiment 2

[0046] A thermoplastic fiber winding pipe equipment, its use method is: use continuous carbon fiber reinforced nylon prepreg tape to wind the pipe, and before the winding starts, the core mold 5 is preheated by the core mold infrared heater 4, so that the surface temperature of the core mold When it reaches 150°C, turn off the heater temporarily, and wrap a layer of PET film on the surface of the mandrel, and the mandrel heater will keep heating during the winding process. Then the tape is unwound by the unwinding device 1, and the prepreg tape is drawn to the winding starting end of the mandrel through the first guide roller 11 and the second guide roller 11' and fixed. Then turn on the mandrel heater again, the temperature guarantees that the prepreg tape wound on the mandrel can be completely melted, and open the first infrared heater preheating device 2 and the second infrared heater preheating device 2', and pass the infrared thermometer 3. Measure the surface temperature...

Embodiment 3

[0048] A thermoplastic fiber winding pipe equipment, its use method is: use continuous aramid fiber reinforced polyethylene terephthalate prepreg tape to wind the pipe, and before the winding starts, 4 pairs of mandrels are passed through the mandrel infrared heater 5 Preheat to make the surface temperature of the mandrel reach 140°C, then temporarily turn off the heater, and wrap a layer of PET film on the mandrel surface, and the mandrel heater keeps heating during the winding process. Then the tape is unwound by the unwinding device 1, and the prepreg tape is drawn to the winding starting end of the mandrel through the first guide roller 11 and the second guide roller 11' and fixed. Then turn on the mandrel heater again, the temperature guarantees that the prepreg tape wound on the mandrel can be completely melted, and open the first infrared heater preheating device 2 and the second infrared heater preheating device 2', and pass the infrared thermometer 3. Measure the surf...

Abstract

The invention relates to thermoplastic fiber winding pipe equipment and applications thereof. The equipment comprises a rack, a trolley, a mandrel, an unwinding device, infrared heater preheating devices, a mandrel infrared heater, an infrared temperature measurement instrument, a tension meter, a pneumatic pressure roller, a horizontal rotating shaft and a guide roller. The applications of the thermoplastic fiber winding pipe equipment comprises the following steps: before pipe winding, preheating the mandrel by using the mandrel infrared heater in advance, then coating the mandrel with a demoulding polyester thin film, unwinding through the unwinding device, pulling a prepreg tape through the guide roller to sequentially pass through the infrared heater preheating device and the tension meter to the winding beginning end of the mandrel and fixing, then starting the infrared heater preheating device for preheating, starting winding program, carrying out tension adjustment, enabling the horizontal rotating shaft to rotate along with the running of the winding program under the control of a servo motor, and carrying out roller pressing on a pipe through the pneumatic pressure roller. Compared with the prior art, the product has the advantages of being higher in toughness, impact-resistant and the like.

Description

technical field [0001] The invention belongs to the technical field of winding molding in the molding process of composite materials, and in particular relates to a thermoplastic fiber winding pipe equipment and a use method thereof. Background technique [0002] Filament winding technology is widely used in the production of FRP pipes, but the FRP pipes currently produced and used are all fiber impregnated with thermosetting resin and then wound into shape, commonly known as thermosetting FRP pipes. Due to the characteristics of the thermosetting resin itself, thermosetting FRP pipes are brittle, have poor impact resistance and are not recyclable. Moreover, during the entire pipeline production process, the environment is very poor due to the volatilization of small molecular substances in the thermosetting resin. Therefore, it is very meaningful to develop a thermoplastic FRP pipe. However, the winding process of fibers impregnated with thermoplastic resin is completely di...
