Description

Technical Field

[0001] This utility model relates to the field of chemical blending equipment technology, and in particular to a quick-change and pouring machine for blending two-component water-based industrial paints. Background Technology

[0002] Water-based industrial paints are environmentally friendly coatings formulated with water as the main solvent, consisting of water-based acrylic resins, epoxy esters, pigments, and additives. Their VOC content is generally below 100g / L (high-end products can be ≤50g / L), and they do not contain benzene compounds, formaldehyde, or other harmful substances, meeting environmental standards. They are non-flammable and non-explosive, safe for transportation and storage, can be diluted with tap water for cleaning tools, have a 15%-20% lower overall construction cost, and offer Grade 1 coating adhesion and an impact resistance of 50kg·cm. Currently, water-based industrial paints are widely used in the automotive (passenger car coating penetration rate 82%), construction machinery (annual usage increase of 40%), and rail transportation (new bidding for high-speed rail in 2024 will fully utilize water-based coatings) fields.

[0003] Water-based industrial paints contain less volatile organic compounds and do not produce toxic or harmful gases during component mixing. Therefore, the mixing process can be carried out in an open environment. However, due to the high viscosity of the raw materials, even with high-pressure pumps such as diaphragm pumps, the pumping energy consumption is high and the conveying efficiency is still low. Therefore, existing technologies generally use a pouring machine to pour the raw materials directly out of the fixed tank by tilting the tank. However, the existing pouring machines are hydraulic trolley structures. Although they can flexibly control the pouring point and use multiple pouring machines to pour materials simultaneously, they cannot precisely control the output. When the tank needs to be changed, the tank needs to be loaded and unloaded from the front. Therefore, in actual operation, the pouring machine needs to be moved from the pouring point to the tank storage location for loading, unloading and replacement, and then the pouring machine needs to be moved back to the pouring point. This is not only cumbersome and inefficient, but also requires at least two workers to operate, increasing processing time and costs. There is room for further improvement. Utility Model Content
