AI Technical Summary

Problems solved by technology

The existing production equipment is to control the technical parameters of graphite paper by adjusting the height of the gate and the gap between the pressure rollers. In actual use, it is found that adjusting the height of the gate and the gap between the pressure rollers can only roughly adjust the density index of graphite paper , the purpose of fine adjustment cannot be achieved, especially in the process of producing wide-width graphite paper, the density control is more difficult, and the extensive control method of the original equipment can no longer meet the production needs

Embodiment Construction

[0014] As shown in the accompanying drawings, the flexible graphite paper production equipment of the present invention includes an expansion device 15 and a calendering device 16 . As shown in FIG. 2 , the expansion device 15 includes a vortex air pump 17 , a stirring device 14 , a cyclone burner 18 , a cooling device 19 and an over-expansion tank 20 . The graphite raw material is sent to the cyclone burner 18 for expansion through the vortex air pump 17, and the expanded graphite passes through the cooling device 19, the graphite expansion zone, and the cyclone cooler in sequence, and then enters the over-expansion tank 20, and is sent to the calendering device 16 through the over-expansion tank 20. The calendering device 16 includes a feeding mechanism and a calendering unit. A density detection mechanism is installed on the calendering unit. A density adjustment mechanism is installed on the feeding device. The signal source 1 and the signal receiver 4, the signal receiver...

Abstract

The production apparatus for flexible graphite paper has signal emitter and signal receiver on the roller to detect the density at all time; and density regulating mechanism on the feeder to regulate the density of the graphite paper. The density regulating mechanism includes frame with block inside the slide way, ratchet roll installed on the block via bearing and elevating leading screw threaded inside the block. The density regulating mechanism receives the signal from the electronic controller to drive the ratchet roll upwards or downwards to regulate the density of the graphite paper.

Description

technical field [0001] The invention relates to a flexible graphite paper production equipment. technical background [0002] The chemical properties of graphite are stable, soft and corrosion-resistant. Graphite paper is an important industrial raw material. Now, the method of industrialized production of graphite paper is: first send the graphite raw material to the expansion furnace, and become expanded graphite at 900°C-1000°C; the expanded graphite is evenly distributed through a vibrating screen after removing sulfur and other impurities in the desulfurizer. The material enters the feeder; after the expanded graphite falls into the feeder, the height of the gate is adjusted according to different technical indicators, the excess material is scraped off, and after being flattened by the ratchet roller, it is sent to the roller for calendering by the conveyor belt to form a Thicker graphite paper base; the graphite paper base is rolled into a roll after being calendered...
