High-thermal-conductivity graphite paper production process and manufacturing equipment thereof

Abstract

The invention discloses a high-thermal-conductivity graphite paper production process which comprises the following steps: feeding, puffing, impacting, separating, centrifugally separating, settling,mixing, pre-pressing, rolling, winding and discharging cloth. Producing and manufacturing equipment used in the pre-pressing process in production comprises a cloth pre-pressing machine and a conveying belt, and fixing seats are mounted at the two ends of the conveying belt; wherein the fixed seat is connected with an accumulation assembly for accumulating and pre-pressing graphite worms falling from which material distribution pre-pressing machine, a motion processing assembly is arranged at the top of the conveying belt, and the conveying belt is provided with a roller for primarily rollingthe graphite worms subjected to pressure maintaining orientation. According to the high-thermal-conductivity graphite paper production and manufacturing equipment, falling graphite raw materials are piled up through the arranged accumulation assembly, the situation that the graphite raw materials are completely laid on a conveying belt is avoided, and meanwhile pre-pressing and width adjustment can be conveniently conducted on processed graphite worms through the arranged motion processing assembly; and the forming state of the graphite worm can be kept conveniently before the graphite worm isformed.

Description

technical field [0001] The invention relates to the technical field of graphite paper production devices, in particular to a high thermal conductivity graphite paper production process and its manufacturing equipment. Background technique [0002] With the acceleration of the upgrading of electronic products and the increasing demand for heat dissipation management of miniature, highly integrated and high-performance electronic equipment, a new heat dissipation technology for electronic products has also been introduced, that is, a new heat dissipation solution for graphite materials. This brand-new natural graphite solution utilizes graphite paper with high heat dissipation efficiency, small footprint and light weight, conducts heat evenly in two directions, eliminates "hot spot" areas, shields heat sources and components while improving the performance of consumer electronics products, Graphite paper (graphite paper): High-carbon phosphorus flake graphite is chemically tre...

AI Technical Summary

Problems solved by technology

[0003] In the preparation process of the existing heat-conducting graphite paper, the graphite raw materials for processing are processed and separated, and then rolled and formed, and the processed graphite raw materials are processed into the required product shape, and the graphite worms are expanded and separated. After being precipitated by the airflow mixer, it is discharged to the pre-compression molding place. The structure of graphite worms is loose. When a large number of graphite worms are transported together for pre-compression, the falling graphite worms are transported through the conveyor belt, and the fluffy graphite worms in the internal space are transported. It is easy to appear fluffy and swell. When the graphite worms pass through the pre-pressed roller, the loose graphite worms are pressed to expand to both sides, which is inconvenient for the wide-width forming of the graphite worms during pre-pressing. For this reason, we propose a high-strength Heat-conducting graphite paper production process and its manufacturing equipment
