Description

Two-component metering discharge pump {PUMP DISPENSING DECIDED QUANTITY WITH MIXING DIFFERENT LIQUIFIED COMPONENTS}

The present invention relates to a two-component metered discharge pump that receives the glue material of the resin and the hardener from a separate tank and supplies the same to a discharge device, and more particularly, even if the number of pumps is reduced. The present invention relates to a two-part metered discharge pump that is easy to apply and easy to maintain.

In general, the two-component glue mixed dispensing apparatus refers to an apparatus for discharging two liquids, which are liquid substances of different types, at a predetermined flow rate and pressure, and having high viscosity such as high viscosity epoxy, urethane, silicone, and paint. It is used for mixing and supplying high-viscosity resin without changing the mixing ratio of the resin, and mixing and supplying special materials such as the main body and the curing agent.

The liquid quantitative dispensing device is used for dispensing by mixing the various resin materials or the main material of the powder and the hardening agent in the correct amount. .

Looking at the lyotropic liquid mixing apparatus of the prior art for mixing and discharging such a subject and a curing agent as follows.

Here, the main and the hardener two glues and argon are supplied from the separate main tank 10 and the hardener tank 12, respectively, and are fixed to each of the main tank 10 and the hardener tank 12, respectively. A plurality of discharge pumps 100 are installed to supply a fixed amount to the mixed discharge device 20.

The mixed discharge device 20 discharges glue of the main agent and the hardener according to the on / off operation of the cylinder.

These main tanks 10, the hardener tank 12, the fixed-quantity discharge pump 100, and the mixed discharge device 20 are controlled through the control unit 30.

2 to 3 is a combination and separation perspective view showing a conventional metered discharge pump 100, the metered discharge pump 100 is largely driven by the motor 112 and the motor 112 to the base 116 The motor gear 114 to be assembled is composed of a motor unit 110 and a pump unit 120 that is meshed with the motor gear 114 to discharge the glue in a quantitative control.

The pump unit 120 has a pair of first and second driving gears 122 and 123 fastened to the back plate 121 and face each other to the gear case 124 and the front. After the plate (125) is assembled, the rod 126 is fitted with the packing 127.

And the back of the back plate 121, the safety plate 128 is assembled like the O-ring 129.

In addition, the housing 132 including the outer gear 131 is assembled to the rod 126 assembled through the front plate 125 to the first driving gear 122 by using the housing nut 130. .

Therefore, when the motor gear 114 of the motor unit 110 starts to drive, the outer gear 131 meshed with the motor gear 114 rotates while the glue unit of the control value preset by the controller in the pump unit 120 rotates. It will discharge the quantity for

However, in the related art, a total of four metered discharge pumps 100 connected to the main tank 10 and the hardener tank 12, respectively, are inefficient, so that the metered discharge pump 100 and the mixed discharge device 20 are inefficient. As it is connected to a relatively long length of hose, when a portion of the hose is stuck, a damping phenomenon occurs due to a change in pressure, and it is difficult to discharge the adhesive in a fixed amount.

In addition, since the motor unit 110 is connected to and driven by the outer gear 131 and the motor gear 114 to the rod 126, the rod 126 is often deformed to damage the inner surface of the pump unit 120. Or adhesive leaked through adjacent surfaces with rods 126 and there was often a problem of sticking.

The present invention has been invented to solve the above problems, the purpose of which is to install two driven gears to be engaged with each other on both sides of the drive gear, a pair through a two-component metered discharge pump having a plurality of inlet and discharge port It can be operated efficiently with the discharge pump of the pump, and the discharge device can be installed directly on the fixed-quantity discharge pump, so that the fixed-quantity can be discharged without damping phenomenon.
