Description

Detailed Description of the Invention "Object of the Invention" (Industrial Field of Application) The present invention is directed to the invention, in which the materials to be supplied are granular materials of different types, properties, shapes, etc., chips of glass LA fibers, metal fibers, etc. Or, even if it is a powder material that can ensure fluidity, it is possible to continuously supply these multiple materials at any mixing ratio and capacity, and the ratio and capacity can be centrally adjusted. The present invention relates to an apparatus for accurately and continuously dispensing a fixed amount, and particularly to an apparatus that can do this with a single unit.

(Prior art) Various types of feeders have been proposed that can supply a fixed amount of a single type of granular material. Suggested the most suitable feeding device for feeding
13221).

On the other hand, in various manufacturing and processing processes, there are cases where it is required to mix two or more types of powder or granular materials in a predetermined ratio and continuously supply them. The idea was to obtain a predetermined blending ratio by installing and combining these.

(Problem to be solved by the invention) However, if feeders are used for each material as in the past, the entire device becomes expensive and equipment costs increase. This required a control device, which was not only expensive but also had poor accuracy.

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks and provide a continuous quantitative feeding device that can feed multiple materials at any mixing ratio in one device, and can also centrally adjust the capacity by adjusting the gate opening degree. It is in.

"Structure of the Invention" (Means for Solving the Problems) The materials targeted by the present invention are resin pellets, fiber chips such as glass fibers and metal fibers, granular materials such as grains, or materials that ensure fluidity. Two or more of these materials can be continuously supplied in fixed amounts at any ratio and capacity using one device.

In the device according to the present invention, a plurality of material receiving ports are opened in a ratio adjusting hopper to supply a plurality of materials, a flap is suspended vertically near the middle of these material receiving ports, and a plurality of material receiving ports are opened in a ratio adjusting hopper to supply a plurality of materials. A separator for setting the blending ratio is arranged so as to partition the inside of the hopper, and can be slid and adjusted by external or direct operation, and the upper part of the separator is engaged in a state in which it is sandwiched between the flaps, and the separator is used for adjusting the ratio. On the exit side of the hopper, a feed roll provided with a non-slip material is disposed, and a control gate is disposed between the feed roll and the feed roll to form a flow path for the supplied material.

The control gate may be configured to have a semicircular cross section and be rotated to adjust the opening degree of the flow path.

(Function) A plurality of materials are sequentially and continuously dropped into the hopper for ratio:A section from each material receiving port, but if the separator for setting the mixing ratio is set to be located in the center of the hopper for ratio adjustment. Each fuller and pu hangs down in a free state.

When the separator is slid and adjusted by external or direct operation, one of the flaps that engages with the upper part of the separator is tilted, and the amount of material that is dropped and supplied from one of the material receiving ports is regulated. At this time, the other flap is free, but it is pushed open by the pressure of the material falling from the other material receiving port, and the slanted flap L is slanted to the side of one flap, allowing more material to be collected. The material will be received.

In this way, the ratio adjustment hopper, which is separated by the mixing ratio setting separator, is filled with each material, but when the feed roll rotates, the materials received in the ratio adjustment hopper pass through the control gate and feed. It is sequentially discharged to the discharge port side through a flow path formed between the rolls and the mixing ratio determined by the position of the separator. In this case, the discharge amount (capacity) is set by adjusting the opening of the flow path and the rotational speed of the feed roll in accordance with the adjustment of the control gate, and a continuous quantity is fed in an integrated manner at an accurate blending ratio.

With the above configuration, there is no need to provide a feeder for each material and combine them, and one machine can accurately and continuously feed multiple materials at any ratio and capacity. .
