Description

Technical Field [0001] The present invention relates to a raw material mixing apparatus for an automobile brake lining molding machine,

The present invention relates to a raw material mixing apparatus for an automotive brake lining molding machine, and more particularly, to a method of mixing raw materials of various kinds having different specific gravity sufficiently and supplying the raw materials to a meter without being cumulated.

Generally, brake linings of automobiles are made by mixing about 20 kinds of raw materials having different specific gravity, such as resin and non-resin, by using a raw material mixing device and supplying them to the measuring machine. The raw materials of the quantified amount measured by the meter are supplied to the molding machine, So that the thermoforming is performed.

As for the raw material mixing apparatus for the automotive brake lining molding machine, there has already been provided a device for drying and mixing a raw material feeder for molding automobile brake pads, which has a dry hopper on the upper part of the mixing hopper, In order to distribute the raw material evenly by preventing the change of physical properties due to drying, a mixer having a plurality of mixing blades connected to the rotating shaft connected to the motor is connected to the upper part of the mixing hopper so as to mix the raw materials In addition, a feed screw is formed in the inner lower portion of the mixing hopper and the feed screw is connected to a shaft rod connected to the motor, so that the mixed raw material is conveyed to the meter.

Therefore, in the raw material mixing apparatus for an automotive brake lining molding machine having the above-described structure, the mixing knife of the mixing machine is rotated by mixing hopper, and the raw material is raised and dropped repeatedly to mix the raw materials. In the process of dropping after the raw materials of various kinds are poured up by a number of mixing blades, the falling speed difference is caused by the specific gravity. As a result, the raw materials are formed by the specific gravity layer, so that the mixing can not be performed properly. In the process of simple transfer to the discharge port by the screw-type transfer blade formed on the shaft end of the screw, not only the mixing can be performed, but rather the layer separation phenomenon by specific gravity is further intensified. Therefore, the raw materials of different characteristics are uniformly distributed I can not. It causes a safety accident at the same time and causes a safety accident. Further, when the raw material is conveyed by the conveying screw, a larger pressing force is applied to the raw material and the raw material is aggregated into a mass. Therefore, when the mass is supplied to the meter, And it causes frequent malfunctions, which leads to a decrease in productivity.

In view of the fact that various kinds of raw materials having different weights are generally not mixed and transported normally through the mixing device, the mixing device of raw material feeder for automobile brake molding is disclosed in Japanese Patent Application No. 10-0752603, However, this is because the auxiliary cup is rotatably connected to the feed cup of the raw material feeder in addition to the mixing device for mixing and conveying the raw materials, and the raw material having the specific gravity layer is supplied before the raw material metered by the meter is supplied to the molding machine However, the cost of adding such a mixing device is increased, and mixing can not be performed by merely turning the mixing device upside down. Therefore, a fundamental solution is urgently required in the workplace.

Patent Document 10-0800269 'Drying and mixing device for raw material feeder for molding automobile brake pads' Patent No. 10-0752603 'Mixing device of raw material feeder for automobile brake molding'

An object of the present invention is to provide a raw material mixing apparatus for an automobile brake lining molding machine which can mix various kinds of raw materials having different specific gravity sufficiently and can remix the raw materials without remineralization.

In order to achieve the above-mentioned object, a raw material mixing apparatus for an automotive brake lining molding machine according to the present invention comprises a mixer having a plurality of openings formed in a screw shape on a shaft rod connected to a motor, And is installed and configured.

The present invention is characterized in that a plurality of acid opening bars 26 formed by screwing various types of powdery raw materials having different specific gravity supplied into the case 10 to the shaft rod 24 of the mixer 12 are quickly spread and mixed And when the mixed raw material reaches the conveyor 14 under the mixer 12, the pair of non-axial screws 30 and 32 is conveyed while being remixed at the minimum pressing force necessary for conveying, It is possible to supply the raw material at a constant amount to the weighing machine because there is no fear of lump of the raw material due to the pressing force of the conveyor 14 and therefore it is possible to prevent the malfunction due to the difference in the supply amount of the raw material in the weighing process of the weighing machine 36, So that it is possible to mix the raw materials having different specific gravity sufficiently. Therefore, the braking due to the bias of the proportion of the raw materials in the lining molding It will not cause performance degradation in the effect of the number of lines, such as being able to prevent the accident.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals are used to designate like elements in the drawings, It will be omitted for the sake of clarity.

Fig. 1 is a front cross-sectional view of the present invention. The present invention is constituted by providing a mixer 12 and a conveyor 14 above and below the inside of a case 10.

The case 10 is formed by communicating the mixing chamber 16 and the transfer chamber 18 at the upper and lower sides of the inner side and forming a discharge pipe 20 at one side of the bottom of the transfer chamber 18.

FIG. 2 is a front view of the mixer used in the present invention, and FIG. 3 is a perspective view of a mixer used in the present invention. The mixer 12 used in the present invention is a motor And a plurality of acid opening bars 26 protruding from the shaft rod 24 passing through the mixing chamber 16 of the case 10 in a lateral direction, So that the powdery raw materials in the mixing chamber (16) are effectively scattered.

Fig. 4 is a plan view of the conveyor used in the present invention. Fig. 5 is a perspective view of the conveyor used in the present invention. The conveyor 14 used in the present invention is installed on the other side of the case 10 And a pair of non-axial screws 30 and 32 connected to the fixed motor 28 and penetrating the transfer chamber 18 of the case 10 so that the front and rear axially unscrewed screws 30 and 32 are engaged with gears The raw material in the transfer chamber 18 is transferred to the discharge pipe 20 having one side of the bottom of the case 10.
