Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fluid mixing and discharging device that mixes multiple types of fluids.

Conventionally, when filling a cylindrical container that stores pumped fluid with fluid, a fluid pressing body provided inside the container so as to be able to move forward and backward is moved from the fluid pressing body to the outer end by pulling an operating rod that protrudes to the outside. The liquid is sucked into the container through the opening at the inner end of the container.

Further, a compression coil spring is provided at the outer end of the fluid presser to press the fluid presser toward the inner end, and this spring applies discharge pressure to the fluid in the container.

However, with conventional systems, if the viscosity of the fluid in the container is high, the resistance when discharging the fluid from the container increases, making it impossible to forcefully push the fluid out of the container, resulting in variations in the amount of fluid discharged. This has the disadvantage that the mixing ratio tends to change when a plurality of fluids are mixed.

In addition, this drawback can be solved by making the compression coil spring that presses the fluid pushing body stronger so that it can forcefully push out the fluid, but with the conventional structure, there is a limit to the force that can be used to pull the operating rod, and the spring is made stronger. I couldn't think of anything to do.

The present invention was developed in view of these points, and in a device that mixes and discharges multiple fluids, the fluid pressing body in the container that stores the fluid can be biased toward the discharge side by a strong compression coil spring. The aim is to make it possible to mix high viscosity fluids at a constant ratio.

Both springs 84, 85 have opposite winding directions.

Further, the fluid pressing body 81 is stopped from moving to the right in the figure at a predetermined position by a retaining ring 87 fitted to the inner peripheral surface of the container 54, and the fluid pressing body 81 in this locked position can be confirmed from the outside. A window hole 88 is provided at the left side of the retaining ring 87 in the figure.

Further, a gauge such as a string is fixed to the right side of the center part of the fluid pressing body 81, and the gauge is connected to the hole in the center of the plate 83.
9, the amount of movement of the fluid pressing body 81, that is, the amount of fluid discharged, can be determined by looking at this gauge.

Next, the action will be explained.

The base 55 of each container 54 is removed from the connection 35, and each base 55 is connected to an external pump (not shown), which pumps fluid into each container 54, such as a base agent of a two-component adhesive or The curing agent is forcibly fed, and the fluid is filled into the container 54 while the fluid pressing body 81 is moved to the right against the compression coil springs 84 and 85.

At this time, the pusher 72 of the operation part 71 provided on each base 55 is moved back so as not to press the check valve 66 as shown in the figure, so that the check valve 66 performs its check action.

Then, when the pins 58 on both sides of the base 55 of each container 54 are aligned with the pin insertion notches 48 of the connection part 35 and the recess 56 of the base 55 is fitted into the right side of the connection part 35 in the figure, the pins of the base 55 are fitted. 58 fits into the pin fitting groove 46 of the connecting part 35, so when the base part 55 is rotated, the pin 58 and the flange part 47 are engaged and the base part 55 cannot be removed from the connecting part 35.

When each of the bases 55 is fitted into the connection part 35, the collar 41 of the connection part 35 is pressed by the fitting convex part 57 of the base 55 and moves to the left in the figure. When the fitting recess 45 of 41 and the fitting protrusion 57 are fitted, the collar 41 is returned to the illustrated position by the compression coil spring 44, and the rotation of the base 55 is stopped.

Each container 54 is attached in this manner. Then, the handle 76 of the operation section 71 provided on each base 55 is turned to rotate the swash plate cam 74 integrated with the operation section 71, and the swash plate cam 74 is slid against the fixed swash plate cam 75. The check valve 66 is separated from the valve seat part 65 by the pusher 72 of the operating part 71 integrated with the swash plate cam 74, and the through holes 61, 62, 63, and 64 are constantly communicated. .

As a result, the fluid in each container 54 is pressed by the fluid pressing body 81 energized by the compression coil spring 84, 85, and constantly presses the spring of the check valve 38 of each connection part 35, causing the steel ball to move toward the valve seat. Through holes 31, 33, 34,
61.62, 63.64 are filled.

Therefore, in this state, when the lever handle 24 is reciprocated and the pistons 8 and 9 are moved forward and backward, the fluid in each container 54 is press-fitted into the cylinder 4.5 when the pistons 8 and 9 move back, and the fluid in the cylinders 4 and 5 and the through hole 33゜31.34,61
．． 62, 63, and 64 become the same pressure, and the check valve 38 operates.

When the pistons 8, 9 advance, the fluid in the cylinders 4, 5 opens the check valve 11.12 and flows into the tip opening 1 of the pressure outlet 15.16.
8.19, and further into the mixing discharge pipe 21, where the two types of fluids are mixed and discharged from the mixing discharge pipe 21.

In this manner, a fixed amount of fluid is sequentially mixed according to the reciprocating motion of the pistons 8 and 9, and fluid having a constant mixing ratio is discharged.

The mixing ratio is adjusted by changing the inner diameter ratio of the through hole 31.32 and the cylinder 4.5.

Further, when each container 54 is emptied and the container 54 is removed from the connecting portion 35 integrated with the device body 1 in order to fill the container 54 with fluid, the pusher 72 of the operating portion 71 is pressed against the check valve 66. The collar 41 of the connecting part 35 is pushed to the left in the figure against the spring 44, and the fitting recess 45 is removed from the fitting convex part 57 of the base 55 of the container 54, and the base 55 is removed. The pin 58 and the pin insertion notch 48 are rotated to a matching position and pulled out from the connection part 35, and the base 55 of the container 54 is connected to an external pump that pumps and supplies filling fluid.

Note that the connection structure of the base 55 to the external pump may be the connection structure of the base 55 to the connection part 35 described above.

As described above, according to the present invention, check valves 38 capable of pressurizing fluid into the cylinder holes 6 and 7 are provided in the through holes 33 and 34 of each connecting portion 35 integrally provided in the device main body 1, and the above-mentioned A base 55 of a cylindrical container 54 that stores the pumped fluid is removably connected to each connection portion 35, and the container 55 is connected to the base of each container 54.
A through hole 6 that communicates the inside of 4 with the through hole 34 of the connecting portion 35.
1.62, 63.64 are provided, and the through hole 6 of each base 55 is provided.
3, a check valve 6 capable of pressurizing fluid into the interior of the container 54;
6 is provided, and the check valve 6 is connected to the check valve 66 of each base 55.
6 forcibly opening the container 54.
Since the fluid pressing body 81 is provided inside the device so as to be movable back and forth, and the compression coil springs 84 and 85 are provided between the fluid pressing body 81 and the outer end of the container 54, the container 54 can be connected to the connecting portion 35 of the device body 1. It is possible to remove the container 54 and fill the inside of the container 54 with the fluid pumped under pressure by the external pump through the through holes 61.62, 63.64 in the base 55 of the container 54. Therefore, the compression coil springs 84, 85 in the container 54 can be selected to be strong, and therefore, the fluid pressing body 81 strongly energized by the compression coil springs 84, 85 can reduce the high viscosity in all the containers 54. of the fluid can be powerfully supplied to the suction part of the device main body 1, a reduction in discharge from some containers can be prevented, and the fluids in the plurality of containers 54 can be accurately mixed at a constant ratio in the device main body 1.
