Abstract

The present invention relates to an apparatus for metering, mixing and ejecting a high-viscosity high-filler resin which has a motor compressed plunger structure provided with a mono-draft or multi-draft type piston and on/off precise opening/closing action valve. The present invention relates to a valve type ejection apparatus which allows ejection of a fixed amount of high-viscosity high-filler liquid resin. The apparatus according to the present invention makes a sub-motor help volumetric metering type pumping upon the two-part mixing and discharging to improve normal ejecting property significantly. The two-part resin supplied to a 2-way line is mixed at an equivalent ratio and ejected at the same time through a mixing element. Thus, it is possible to minimize an error in mixing ratio. In addition, when the motor compresses a piston, a special seal for a high-viscosity high-filler resin is mounted to each end to provide high pressure resistance and wear resistance. Particularly, the action valve responsible for on/off during opening/closing for ejection fundamentally interrupts counterflow of a resin solution to improve precision in ejection significantly.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-viscosity, high-viscosity mixed dispensing device for a high-viscosity, high-filler resin of a motor-driven plunger structure having a piston having a double- pressing with automatic opening and shutting piston and valve}

The present invention relates to a valve-type discharging device capable of quantitatively discharging a high-viscosity, high-pillar type liquid-type resin, and the discharging device is capable of performing pumping of a volumetric- And the two-liquid type resin supplied to the 2-way line is mixed at an equal ratio and then discharged at the same time by the mixing element so that the error rate of the mixing ratio is minimized. In addition, A special seal (SEAL) exclusively used for high filler is attached to each end to provide high pressure resistance and abrasion resistance. Particularly, the actuation valve for on / off (ON / OFF) Wherein the piston and the individual operating valve are connected to each other by a piston The present invention relates to a metered mixed ejection apparatus for a high filler resin having a motor plunger pressing structure.

In general, the two-component mixed ejection apparatus is a device for mixing and discharging a liquid, which is a liquid material having a different kind of liquid, from each other at a predetermined flow rate and pressure, and is composed of a high viscosity resin such as epoxy, urethane, silicone, The resin of high viscosity is mixed and supplied without changing the mixing ratio, and mixed with a special material such as a hardener and a hardener to supply and supply.

The above-mentioned two-component mixing / dispensing apparatus is widely used because it mixes the various resin materials to be mixed and the curing agent in a precise amount with the subject of the powdered coating material and discharges it with a small error range of the discharge amount, have.

However, in the conventional liquid mixed ejection apparatus as described above, the apparatus for removing the bubbles contained in the raw material constitutes one system, so that the equipment is uneven, the raw materials in the tank are used up, the raw material is put into the tank again, There is a problem in that the equipment must be stopped during the process of removing the water and the productivity is deteriorated.

In addition, the conventional liquid mixed ejection apparatus has a problem in that it can not be quantitatively withdrawn due to the pulsation phenomenon periodically generated by the rotation structure of the pump due to the failure to supply the correct pressure and the quantity of the liquid through the pump.

The conventional two-liquid mixing / dispensing apparatus feeds the mixed liquid to the vacuum bottle through the operation of a vacuum pump while injecting it into the stirred tank to mix the liquid and the curing agent. In order to supply the liquid and the curing agent, There is a problem in that the cost due to the process is spent and the supply is delayed.

In addition, in the conventional two-liquid mixing / dispensing apparatus, since the second solution is supplied through the pump in a state in which the solution is first sucked by the vacuum bottle with the vacuum pump, the amount of the solution to be supplied must be adjusted while passing through each pump, There is a problem that it is difficult to control due to loss of generated pressure and liquid amount, and it is difficult to supply a fixed amount due to irregular flow such as pulsation phenomenon generated in the motor.

Accordingly, the applicant of the present application has made improvements to the above-mentioned conventional problems by being registered with the patent No. 10-0779216 on the above-mentioned problems.

That is, the above-mentioned patent includes a body portion formed on both sides of a raw material placing portion for placing a raw material can in order to mix and dispense the two solutions, and an upper portion fixed to both sides of the raw material can placed on the raw material holding portion side of the body portion by a feed and fixing plate A conveying bar is formed at the center of the conveying bar, and a conveying bar fastening portion is formed at a lower portion of the conveying bar. And a supply tapered portion that is vertically inwardly raised to have a supply tapered portion so as to collect the raw material liquid, wherein the supply taper portion is connected to the supply- A raw material liquid flowing into an inlet port of the supply port of the supply unit is driven by a driving motor fixed to the motor fixing unit, A pumping portion formed with a gear pump to pressurize the raw material liquid by rotation of the discharge gear coupled to the drive shaft by coupling and to discharge the raw material liquid in a predetermined amount to the discharge port side and a discharge port formed to discharge the mixed solution by directly connecting the discharge pipe to the discharge port side of the pumping portion And the mixed discharge portion, the above-mentioned conventional problems are solved.

However, in connection with the above-mentioned registered patent, a more uniform and stable mixing force is demanded in the art than in the case of a mixed dispersion liquid, and a discharge alternative for a high viscosity high pilling resin liquid is required.

In other words, the conventional double-fluid mixing device is a piston-pumping type feeding device which is moved up and down like a syringe and then discharged, and when the piston rises to the top, the check ball is lifted and dropped from the check sheet.

On the contrary, when the check ball at the top pushes the check sheet, the air is blocked so that the liquid can be sucked in, so that the solution is filled in. Then, when the piston moves back to the bottom, the check ball at the bottom pushes down the check sheet, Do not fall.

At this time, the check ball at the upper end is opened by the pressure and the liquid is discharged to the outside. After the liquid is filled, the liquid is discharged so that the piston moves either upward or downward.

However, this conventional method has an advantage that a high pressure can be used, but since the movement stops when the piston is shifted up and down, there is a problem that the pressure transmission of the liquid temporarily stops at this portion, and a pulsation phenomenon occurs.

In addition, since the prior art described above has difficulty in smooth bonding and application due to insufficient pumping performance for discharging a high-capacity high-viscosity resin, in particular, when the connecting coupler between the motor and the gear pump continues to be engaged when the motor is overloaded, Causing damage to itself, leading to a large safety accident.
