That is, the carbon ground module can maintain a low ground resistance by constituting the carbon resistor 10 and the stem 20 which are graphite materials, and the ground resistance variation ratio due to the ground environment change due to hygroscopicity etc. It is a small grounding resistor.

However, in the case of a manufacturing apparatus for forming a carbon resistor according to the prior art, a product is produced from an extrusion or injection molding apparatus, that is, a carbon resistor material is injected into a metal mold having a certain standard, Thereby forming a carbon resistor.

Therefore, when the carbon resistor is produced from the extrusion molding apparatus, the carbon nanotubes that are elongated in the longitudinal direction should be cut in a predetermined length unit. In the case of the mold frame, a plurality of mold frames corresponding to various unit lengths of the carbon resistor are provided There is a problem that the investment cost such as the mold cost is increased.

 In addition, since the manufacturing method through the extrusion or injection molding process must be carried out manually by the manpower for each process, the labor force, the cost and the time required are increased, resulting in an increase in the unit price of the product, There is a problem that the defective incidence rate is increased.

The reason why the stirrer 100 is composed of the first agitating cylinder 100a and the second agitating cylinder 100b is that the supply of the material for producing the carbon resistor C is smoothly performed.

In other words, any one of the first agitating cylinder 100a or the second agitating cylinder 100b operates in advance to generate a sludge-like material, and then the remaining agitating cylinders 100a and 100b are operated to discharge the sludge So that the sludge material supply can be stopped without repetitive sequential supply.

In addition, the stirrer 100 is not limited to the two structures formed by the first agitating cylinder 100a and the second agitating cylinder 100b, but may be formed in a configuration of more than two.

In addition, the mixed material constituting the carbon resistor (C) is composed of expanded tin, expanded vermiculite, graphite, cement, acrylic resin, urethane resin, sodium silicate and the like.

The feed conveyor 200 is preferably a screw (S) type conveying material from the stirrer 100 to the next process step so that stirring of the material can be performed during conveyance. However, A flat type belt type may be applied.

It is preferable that the feed conveyor 200 is installed in an upward inclined structure in which one end in the longitudinal direction of which the material is supplied from the agitator 100 is located at the lower side and the other end is located at the upper side.

This is to increase the viscosity of the material so that the molding action of the compression molding unit 400 can be easily proceeded by naturally inducing the dehydration effect of the moisture contained in the sludge material.

The configuration and operation using the screw S of the feed conveyor 200 are well known in the art and thus a detailed description thereof will be omitted.

The pressurizing unit 300 for introducing the material is provided below the other end in the longitudinal direction of the feed conveyor 200 and guides the material conveyed on the feed conveyor 200 to the forming position And presses and moves the molded carbon resistor.

Specifically, the pressing unit 300 for introducing a material has a channel-like structure with a bottom opened and is partitioned into an internal working space part 301 and a material storage part 302, and on the upper surface of the material storage part 302 A pressurizing cylinder 320 disposed in the operating space 301 of the body part 310 and capable of linearly reciprocating the body part 310 forward and backward, ).

The body portion 310 is formed by bending both sides in the longitudinal direction and is partitioned into a working space portion 301 and a material storage portion 302 by forming a partition wall member 311 in the center portion of the body portion 310.

Although not shown in the drawing, elastic louvers (not shown) are formed on the bottom surfaces of the inner wall surfaces of the body portion 310 facing the partition member 311 and the partition member 311.

That is, the elastic louver is provided to cleanly move the sludge falling into the material storage unit 302 in the conveying direction.
