Problems solved by technology
[0002] At present, most of the existing dispensing and encapsulation operations use manual proportioning, and then manual injection or encapsulation of the workpiece. The disadvantages are: large ratio error, uneven mixing, uneven surface, serious waste of resin, and resin loss. Volatility and peculiar smell cause air pollution in the working environment of operators, which is harmful to the human body, and the qualified rate of production workpieces is low. For workpieces with high requirements, only imported equipment can be used, and the cost is high.

The invention relates to the technical field of glue injection machinery, in particular to a single-cylinder-driving ratio-variable metering device which is provided with a base. The device is characterized in that a rocker-arm support is fixed on the base; the lower end of a rocker arm is hinged with the base through a rocker arm shaft, and the upper end is hinged with the base through a driving cylinder; a glue solution driving arm is arranged on one side of the rocker arm, and a hardening liquid driving arm is arranged on the other side; ratio adjusting chutes are arranged on two lateral surfaces of the rocker arm respectively, and ratio adjusting sliders are arranged in the ratio adjusting chutes; the lower end of the glue solution driving arm is connected with a guide rod I in a sliding manner, and the upper end is connected with a glue solution driving rod; two ends of each of the guide rod I and a guide rod II are fixed on the base through a guide rod base respectively; one end of the glue solution driving rod is connected with the guide rod base in a sliding manner, and the other end is connected with a glue solution metering pump; the lower end of the hardening liquid driving arm is connected with the guide rod II in a sliding manner, and the upper end is connected with the hardening liquid driving rod; one end of the hardening liquid driving rod is connected with the guide rod base in a sliding manner, and the other end is connected with a hardening liquid metering pump. The metering device has the advantages of small ratio error, even mixing, smooth workpiece surface, and the like.
Description
technical field [0001] The invention relates to the technical field of glue injection machinery, in particular to a single cylinder driven variable ratio metering device for glue dispensing. Background technique [0002] At present, most of the existing dispensing and encapsulation operations use manual proportioning, and then manual injection or encapsulation of the workpiece. The disadvantages are: large ratio error, uneven mixing, uneven surface, serious waste of resin, and resin loss. Volatility and peculiar smell cause air pollution in the working environment of operators, which is harmful to the human body, and the qualified rate of production workpieces is low. For workpieces with high requirements, only imported equipment can be used, and the cost is high. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned deficiencies in the prior art, and provide a single-cylinder-driven variable ratio metering device with simpl...
