Automatic wire coiling machine

Abstract

The invention provides an automatic wire coiling machine. The automatic wire coiling machine comprises a rack, and an unwinding device, a wire guide device, a wire coiling main shaft device and a pressing device which are arranged on the rack, wherein the unwinding device comprises an unwinding disc for placing a pre-impregnated belt and a plurality of tensioning wheels; the wire guide device is arranged at one side of the unwinding device; a wire guide hole is formed in the wire guide device; the wire coiling main shaft device comprises a rotary motor and a driving disc which is controlled bythe rotary motor to rotate; the driving disc is provided with a round wire coiling jig; the pre-impregnated belt on the unwinding disc is dragged to the wire guide device through the tensioning wheels and passes through the wire guide hole to form a silk shape and then is wound on the round wire coiling jig; the pressing device comprises a bracket, a linear air cylinder and a pressing disc; the linear air cylinder is fixed on the bracket; the pressing disc and the linear air cylinder are coaxially connected; the pressing disc is located just above the round wire coiling jig. According to theautomatic wire coiling machine, carbon fiber pre-impregnated silks are uniformly and stably coiled on the round wire coiling jig, the tightness is good and the thickness is uniform, so that the strength of a product is ensured, and batch and standard production is realized.

Description

technical field [0001] The invention relates to composite material coiling equipment, in particular to an automatic coiling machine suitable for bicycle wheels. Background technique [0002] Carbon fiber is a microcrystalline graphite material obtained by carbonizing and graphitizing organic fibers. Carbon fiber is a new material with excellent mechanical properties. Its specific gravity is less than 1 / 4 of that of steel. The tensile strength of carbon fiber resin composite materials is generally 7-9 times that of steel, and the tensile modulus of elasticity is also higher than that of steel, so carbon fiber has a broad application prospect in engineering. [0003] The transformation of the bicycle from the original means of transportation to the current leisure sports and fitness tool cannot be ignored, and the innovation of its raw materials cannot be ignored, and it is the carbon fiber composite material that completes the transformation of the use style and quality.

AI Technical Summary

Problems solved by technology

The brake edge of the existing carbon fiber rim is manually coiled on the jig with the prepreg produced in advance, and there are problems such as uneven speed of the coiling process, uneven tension of the thread, and difficulty in stripping. Therefore, it is necessary to develop a Automatic coiling equipment to improve coiling effect and reduce labor cost
