Problems solved by technology

[0004] Since the traditional pipe winding equipment is mainly used for winding large pipes and gas cylinders, its winding accuracy is limited when the winding angle is small, and it cannot meet the stability requirements of the test. At the same time, it is expensive and occupies a large area, so it is not suitable for glass fiber factories, blades, etc. factory use

Embodiment 2

[0044] After unwinding the glass fiber yarn, pass through the dipping tank, and then pass through image 3 The through hole of the cable guide shown is fixed on the winding mold, turn on the cam motor to adjust the position of the cable guide to the edge of the mold, and pour a sufficient amount of unsaturated polyester resin into the dipping tank to completely impregnate the yarn in the resin , adjust the rotation speed ratio of the mold motor and the cam motor. It is desired to set the cable angle to 0.5° and the mold width to 200mm. According to the trigonometric formula, the horizontal displacement distance of the cable is 1.75mm. After setting up the machine, turn on the motor to start winding. The winding thickness is required to be 2mm. According to the yarn density and winding angle setting, the number of winding layers is calculated to be 3 layers. After winding, turn off the motor, close the mold, and release the mold after curing according to the curing method of th...

Abstract

The invention provides glass reinforced plastic winding equipment. The equipment comprises a frame, and a power system and a winding system which are arranged on the frame, wherein the winding system comprises a cam mechanism, a winding displacement mechanism and a mold; the winding displacement mechanism is arranged on the cam mechanism and is driven to do reciprocating motion through the cam mechanism; the mold and the winding displacement mechanism are arranged parallel to each other; and the mold and the cam mechanism are driven through the power system. The equipment provided by the invention has high winding accuracy and a small producing area. The invention also provides a glass reinforced plastic winding method.

Description

technical field [0001] The invention relates to the field of polymer material processing equipment, in particular to a glass fiber reinforced plastic winding device and a glass fiber reinforced plastic winding method. Background technique [0002] With the extensive application of glass fiber composite materials in aerospace, automobile industry, wind energy and civil fields, the testing of glass fiber composite materials is becoming more and more stringent. As one of many test items, the test of winding glass fiber reinforced plastic sheets is an important design parameter. , has been adopted by major wind power blade design manufacturers at home and abroad. Since there are many links in the preparation of wound FRP sheet samples, which will have a significant impact on the test results, winding equipment is one of the important factors. [0003] For the preparation of glass fiber yarn products winding FRP plates, the method is given in ISO 1268-5, but no description is ma...
