Two-component servo metering cylinder

Abstract

The invention belongs to the technical field of gluing equipment, especially a two-component servo metering cylinder, which includes a glue supply mechanism A and a glue supply mechanism B, the A glue supply mechanism includes a first servo motor, and the bottom of the first servo motor is fixed The first electric cylinder main body is installed, the output shaft of the first servo motor and the input shaft of the first electric cylinder main body are fixedly connected together, and the bottom of the first electric cylinder main body is fixedly installed with the first master cylinder, so A first glue inlet valve is fixedly installed on one side of the first master cylinder. The sewing device of the present invention is directly installed at the end of the equipment, directly connected to the rubber mixing pipe, and there is no hose transition in the middle, which completely eliminates the influence of the pipeline system on the two-component ratio measurement, and is not affected by viscosity, temperature, mixing ratio and gun stop interval time The influence of the influence, and the ratio is accurate, the ratio is adjustable, and the ratio error caused by factors such as temperature / pipeline / pressure changes during the automatic application of two-component glue is completely solved.

Description

technical field [0001] The invention relates to the technical field of gluing equipment, in particular to a two-component servo metering cylinder. Background technique [0002] In the existing two-component glue applicator system, most of the glue mixing equipment of traditional manufacturers adopts a fixed ratio metering cylinder, and uses the same power source (pneumatic or electric) to push out A / B at the same time. Two-component glue, then the glue passes through a certain length of hose through the glue valve, into the glue pipe, and finally applied to the workpiece. [0003] But, existing two-group gluing machine also has following shortcoming: [0004] 1. Since the viscosity of the glue is very sensitive to changes in temperature and has a large deviation, the so-called simultaneous release of glue by traditional equipment is actually due to changes in viscosity (including changes in the glue itself of components A and B and changes in viscosity between A and B glues...

Problems solved by technology

[0004] 1. Since the viscosity of the glue is very sensitive to changes in temperature and has a large deviation, the so-called simultaneous release of glue by traditional equipment is actually due to changes in viscosity (including changes in the glue itself of components A and B and changes in viscosity between A and B glues) Poor), the actual amount of glue released is different at different temperatures;

[0005] 2. When a power source pushes the two-component proportional cylinder to output glue, due to the difference in viscosity, the low-viscosity glue will enter the mixing pipe before the high-viscosity glue when the glue mixing valve is opened, and vice versa when the glue mixing valve is closed. Synchronously output and close glue;

[0006] 3. The proportional cylinder and the rubber mixing valve are connected by a hose, the hose part will be longer, and the error caused by the deformation of each hose itself will increase;

[0007] Since the existing two-group gluing machine cannot guarantee the accuracy of the ratio and the reliability of the repetition, it is completely unable to meet the requirements of the modern process. Therefore, a two-component servo metering cylinder is proposed.
