Three-dimensional knitting machine for carbon fiber preforms

Abstract

The invention discloses a three-dimensional knitting machine for carbon fiber preforms. The three-dimensional knitting machine comprises a rack. An annular disperser, a track disc, an automatic driving yarn carrying device, a shaping device, a pre-forming carding device and a pre-forming device are sequentially arranged on the rack from top to bottom. A plurality of circles of threading holes areformed in the track disc. A plurality of circles of wave-shaped track grooves are formed in the bottom face of the track disc. Every two adjacent circles of threading holes are connected through one circle of wave-shaped track groove. The wave trough of each wave-shaped track groove bypasses the threading holes in the inner circle in every two adjacent circles of threading holes. The wave crest ofeach wave-shaped track groove bypasses the threading holes in the outer circle in every two adjacent circles of threading holes. The wave crests and the wave troughs of every two adjacent circles ofwave-shaped track grooves intersect with each other. The automatic driving yarn carrying device comprises an upper sliding box, a middle control box and a lower yarn clamping assembly. The productionof the carbon fiber preforms by the equipment is convenient and fast, and the production cycle is greatly shortened.

Description

technical field [0001] The invention relates to the field of carbon fiber preforms, in particular to a three-dimensional weaving machine for carbon fiber preforms. Background technique [0002] At this stage, most of the carbon fiber prefabricated bodies produced in the photovoltaic and semiconductor industries are made of carbon fiber cloth and mesh tires, which are superimposed with semi-manual acupuncture by acupuncture machines. The disadvantages are long production cycle, large waste and low strength. With the continuous increase of industry demand, especially with the explosive growth of my country's semiconductor industry, the demand for large-diameter, high-strength carbon fiber prefabricated crucibles is becoming more and more vigorous. The existing production process cannot meet the technical needs of users, so it is urgent to develop a carbon fiber crucible product that can produce three-dimensional structures, save labor and materials, have a large diameter and ...
