Specific-proportion bi-component fluid output device

Abstract

The invention discloses a specific-proportion bi-component fluid output device. The specific-proportion bi-component fluid output device comprises a power device, a driving proportion adjusting mechanism and high pressure cylinder components. At least three sorts of the high pressure cylinder components are arranged. The driving proportion adjusting mechanism is provided with two power output ends, and each power output end is provided with the corresponding high pressure cylinder component. The driving proportion adjusting mechanism is used for conducting equilibrium partitioning on an input power of the power device and outputting the power, and the differences of areas among the multiple sorts of the high pressure cylinder components are arranged in multiple sorts of proportions. Six sorts of different proportions of 1 to 1, 1.5 to 1, 2 to 1, 2.5 to 1, 3 to 1 and 4 to 1 of bi-component fluid definite-proportion conveying can be achieved by setting the proportions of different values of cross sectional areas between cylinder body inner cavities and pistons among the various high pressure cylinders, so that the higher and higher technical requirement by users is met, and the matching precision of the spraying is improved. In addition, the structure is simple; the cost is low; the convenience and practicability are achieved; the popularization is easy.

Description

technical field [0001] The invention relates to a paint spraying equipment, in particular to a specific ratio two-component fluid output device. Background technique [0002] With the increasing degree of automation, the application of spraying equipment is becoming more and more extensive, and it penetrates into many fields of the national economy. There are also various types of two-component spraying equipment, and the mixing ratio of various coatings Both have appeared, and the demand for high-precision fixed-ratio spraying technology of two-component fluids with three different ratios of 1:1, 1.5:1, and 2:1 is becoming more and more common. At the same time, each two-component coating has a corresponding spraying The pressure demand makes the spraying pressure ratio of the equipment more types. The current technology is to control the mixing ratio of the two-component paint by adjusting the movement stroke. The disadvantage of this method is that the accuracy of the mix...

[0002] With the increasing degree of automation, the application of spraying equipment is becoming more and more extensive, and it penetrates into many fields of the national economy. There are also various types of two-component spraying equipment, and the mixing ratio of various coatings Both have appeared, and the demand for high-precision fixed-ratio spraying technology of two-component fluids with three different ratios of 1:1, 1.5:1, and 2:1 is becoming more and more common. At the same time, each two-component coating has a corresponding spraying The pressure demand makes the spraying pressure ratio of the equipment more types. The current technology is to control the mixing ratio of the two-component paint by adjusting the movement stroke. The disadvantage of this method is that the accuracy of the mixing ratio of the two-component spraying equipment can be adjusted. It is not high, but the past integrated two-component spraying equipment has a small structure and is portable, which can meet the accuracy requirements of the mixing ratio of two-component coatings. However, the mixing ratio of the coating and the spraying pressure of the equipment have been fixed, and the user has other performance requirements. Only new equipment can be purchased; the pump base, paint cylinder, piston rod, etc. of the new equipment are all customized, which requires a long processing cycle and is not suitable for a short production cycle.
