Description
Technical Field
The invention relates to carbon fiber composite material production equipment, in particular to a carbon fiber flat plate prefabricated body needle machine.
Background
Most of carbon fiber preform production enterprises use traditional non-woven material needling equipment, a platform is additionally arranged at each needling input end and output end of the carbon fiber preform production enterprises, a transmission shaft is arranged outside the platform and at the bottom of a rack, a mesh curtain is adopted to perform sewing adjustment after bypassing the platform and the transmission shaft, and the transmission shaft is controlled by a motor to move, so that the mesh curtain realizes reciprocating circular motion, and the preform is driven to transmit needling.
The carbon/carbon composite material has little proportion in the carbon fiber composite material, and the carbon fiber preform mainly provides a carbon skeleton of the carbon/carbon composite material, and belongs to the non-standard industry. Most of domestic carbon fiber preform manufacturing enterprises basically use ordinary non-woven needle looms, and the research on the selection of felting needles is more in the early stage, and in order to match the production requirement, some enterprises begin to carry out the transformation optimization of the needling equipment in the later stage.
The carbon fiber flat plate preform is different from the traditional non-woven material needling process, adopts a carbon fiber plane fabric and a carbon fiber net tire, and is subjected to layer-by-layer laying and needling compounding through a layer laying design. A non-woven needle loom for producing carbon fiber prefabricated bodies in industry is characterized in that conveying of the prefabricated bodies is mainly circularly driven by a net curtain, namely, the net curtain is sleeved on a platform of the needle loom, a transmission shaft below a machine table stretches the net curtain straight, and after sewing, the tensioning degrees of the left side and the right side of the machine table are adjusted to ensure consistent tension. The flat plate preform needling process comprises layering, needling and conveying the preform back needling input end, and the steps are circulated.
This process creates several problems:
(1) the operation requirement of the mesh curtain sewing on workers is high, and the sewing joint is easy to cause needle breakage during initial needling;
(2) the net curtain is easy to loosen and damage in the needling process and needs to be adjusted or replaced in time;
(3) tension adjustment of the left end and the right end of the net curtain is inconsistent, so that the flat plate prefabricated body is easy to output obliquely, surface acupuncture traces are deflected, and the pore uniformity of the prefabricated body is influenced;
(4) the net curtain is easy to damage by reciprocating needling in the same position area, so the net curtain needs to rotate circularly and needs to be fixed by a worker at the needling output end connecting plate and transported to the needling input end, which wastes manpower and working hours and has low needling output efficiency;
(5) a plastic film is usually required to be placed on the net curtain, and then carbon fiber plane fabrics and net tires are laid for needling, so that the carbon fibers are prevented from being directly adhered to the net curtain, otherwise, needle holes of the wool supporting plate are easily blocked, and needle breakage is caused;
(6) the flat plate prefabricated body cannot be prevented from being dragged in the back-and-forth transportation process, and corner deformation and layering are easily caused.
Therefore, there is a need for a structurally optimized lancing device of this type to overcome the above-mentioned drawbacks.
