Carbon fiber flat plate preform needling machine

Abstract

The invention provides a carbon fiber flat plate preform needling machine. The carbon fiber flat plate preform needling machine comprises a needling mechanism and a conveying mechanism. The needling mechanism is assembled on a rack, and the conveying mechanism is assembled on the rack and located below the needling mechanism. A preform to be processed is placed on the conveying mechanism, the conveying mechanism drives the preform to move in the longitudinal direction, and the needling mechanism performs needling processing on the preform. The conveying mechanism comprises a supporting assembly and a driving assembly, a space for placing the preform is formed in the supporting assembly, the driving assembly is assembled on the rack and is connected with the supporting assembly, and the driving assembly drives the supporting assembly to linearly reciprocate in the longitudinal direction. According to the needling machine, the supporting assembly is driven to move by a lead screw structure, a net curtain is not required, a foam board or wool felt is adopted to replace a net curtain and a plastic film, and preparation procedures are reduced for operators before needling. In a needlingprocess, the number of operators who convey flat plate preforms back and forth is reduced, and corner deformation and layering due to preform dragging are avoided.

Description

technical field [0001] The invention relates to carbon fiber composite material production equipment, in particular to a carbon fiber flat plate prefabricated needle punching machine. Background technique [0002] Most of the carbon fiber prefabricated body production enterprises use traditional non-woven material acupuncture equipment, and install a platform at the input and output ends of the acupuncture, and install the drive shaft outside the platform and the bottom of the frame, and use the net curtain to bypass the platform and the drive shaft Finally, the stitching is adjusted, and the motor controls the movement of the drive shaft to make the mesh curtain realize the reciprocating circular motion, thereby driving the prefabricated body to transmit acupuncture. [0003] Carbon / carbon composite materials account for a small proportion of carbon fiber composite materials, and carbon fiber prefabrication mainly provides its carbon skeleton, which is a non-standard indust...

AI Technical Summary

Problems solved by technology

[0006] (1) The stitching of the mesh curtain has high requirements for the operation of the staff, and the stitching joint is easy to cause the needle to break during the initial acupuncture;

[0007] (2) The mesh curtain is easy to loosen and break during the acupuncture process, and needs to be adjusted or replaced in time;

[0008] (3) The tension adjustment at the left and right ends of the mesh curtain is inconsistent, which may easily cause the output of the flat prefabricated body to be inclined, and the needle marks on the surface to be biased, which will affect the uniformity of the pores of the prefabricated body;

[0009] (4) The net curtain is easy to be damaged by reciprocating acupuncture in the same position area, so the net curtain needs to be rotated circularly, and an employee needs to be fixed to connect the plate at the acupuncture output end and transport it to the acupuncture input end, which wastes manpower and working hours. Low output efficiency;

[0011] (6) It is unavoidable to drag the flat prefabricated body during the back and forth transportation, which may easily cause corner deformation and delamination
