Description

Filling machine

The invention relates to a glue pouring machine, in particular to a two-component glue pouring machine.

In the two-component glue filling machine, due to the characteristics of the glue itself, a chemical reaction occurs when the A glue and the B glue are mixed, so the A glue and the B glue are usually stored separately, and then mixed in use. When continuous extrusion is required, it takes a long time to introduce and mix A glue and B glue separately, which may cause the glue to solidify in the dispensing system. It is necessary to replace all blocked components in the dispensing system before continuing to use. Significantly waste consumables and increase time for replacement parts.

In view of this, it is necessary to provide a two-component glue filling machine which can prevent glue blocking.

A glue dispenser for mixing A glue and B glue and performing a dispensing operation, wherein the glue dispenser includes a liquid dispensing mechanism, a dispensing mechanism, a glue dispensing mechanism, and a control mechanism, and the liquid dispensing mechanism It includes an A hose for storing A glue, a B hose for storing B glue, and a pressure regulating valve. The pressure regulating valve is used to access compressed condensed air. The glue outlet mechanism includes a mixing pipe and a A needle is provided at the lower end of the mixing tube, and the A rubber tube, the B rubber tube, and the pressure regulating valve are connected to the mixing tube through the distribution mechanism. The control mechanism is connected to the distribution mechanism, and is used to control the A glue, B glue, and condensed air to be introduced into the mixing tube individually or in mixture. When dispensing, the condensed air is first introduced into the mixing pipe, and then A glue and B are introduced. Glue to the mixing tube and dispense through the needle.

Compared with the conventional technology, the glue filling machine of the present invention adds the access of compressed condensed air. Before introducing the A glue and the B glue into the mixing pipe, the compressed condensed air is first introduced and used. Condensing air reduces the temperature of the mixing tube, so that when the A glue and B glue are subsequently introduced, the temperature of the mixing pipe is lower, thereby reducing the temperature of the A glue and B glue mixed glue liquid, and extending the AB mixing The curing time of the glue in the mixing tube can prevent the glue from blocking.
