Description

Technical Field

[0001] The invention relates to a coating production device, in particular to a feeding system of a water-based coating stirring device. Background Art

[0002] As an emerging type of paint, water-based paint is different from oil-based paint in that it mainly uses water as a solvent and does not contain harmful volatiles such as benzene, toluene, xylene, formaldehyde, etc. It is more friendly to the human body and the environment. No toxic gases will be released during the construction process, which will not affect the health of workers or pollute the air quality. In addition, the viscosity of water-based paint is moderate, the fluidity is good during the painting process, the operation is simple, and it is not easy to drip and bubble. In addition, the drying speed is fast, and the paint has good adhesion and hardness after drying, which improves the coating efficiency and saves construction time.

[0003] The main components of water-based paints are film-forming substances, pigments, fillers, additives and water, among which film-forming substances and water account for the largest proportion and are all fluids. These ingredients need to be mixed in a fixed ratio and the mixing process must be completed in a mixing device. In order to improve the level of automation in the production of water-based paints and ensure the accuracy of the ingredients, the existing mixing equipment is generally equipped with an automated batching system, which is mainly used for the automatic and accurate addition and feeding of fluid ingredients. The most critical part of the automated batching system is the pump and flow detection equipment. Each fluid raw material is independently equipped with at least one set of pumps and flow detection equipment. The more types of fluid raw materials, the more pumps and flow detection equipment are required. High-precision pumps and flow detection equipment are expensive, so the procurement cost of the automated batching system has remained high. In order to reduce the production cost of water-based paints, it is urgent to develop a set of cost-controllable, quantitatively accurate mixing equipment feeding system. Summary of the invention

[0004] The invention provides a feeding system for water-based paint stirring equipment, which solves the problem in the prior art that the purchase cost of an automated fluid batching system remains high.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: a feeding system of a water-based paint stirring equipment, characterized in that it includes a fixed seat, a guide rod vertically fixed on the fixed seat and a lifting seat slidably matched with the guide rod, the fixed seat is provided with a servo electric cylinder for driving the lifting movement of the lifting seat; the feeding system also includes a plurality of quantitative feeding modules, the quantitative feeding modules include a barrel, a measuring cylinder fixed on the fixed seat, a piston arranged in the measuring cylinder, a connecting rod connected to the piston, a feed pipe and a discharge pipe, the other end of the connecting rod is fixedly connected to the lifting seat, the feed pipe and the discharge pipe are both connected to the bottom of the measuring cylinder, the other end of the feed pipe is connected to the barrel, the feed pipe is provided with a first control valve, the discharge pipe is provided with a second control valve, and the discharge pipe is connected to the paint stirring equipment;

[0006] All pistons rise and fall synchronously with the lifting seat and have the same lifting distance. When the piston rises, the second control valve is in a closed state and the first control valve is in an open state; when the piston descends, the second control valve is in an open state and the first control valve is in a closed state. By controlling the cross-sectional areas of different barrels, different fluid inflow and outflow amounts can be achieved under the premise of the same piston feed stroke.

[0007] The present invention can customize the number of quantitative feeding modules and the size of the measuring cylinder according to the actual proportion of the ingredients of the water-based paint. For example, a water-based paint is composed of 80 parts of acrylic resin, 35 parts of water and the remaining ingredients. The remaining ingredients are non-fluid substances or fluid substances with too low content, which are not suitable for the automatic addition of the present invention. The present invention is mainly used for the automatic feeding of fluid substances that account for a large proportion of water-based paint. For this water-based paint, the present invention needs to prepare two sets of quantitative feeding modules, and the cross-sectional area ratio of the corresponding two measuring cylinders is 80:35. The measuring cylinder of the present invention is used for temporarily storing fluid. When the stirring device is in operation, the measuring cylinder can be filled by the present invention, the second control valve is closed, the first control valve is opened, the servo electric cylinder pushes the lifting seat to lift up at a uniform and stable speed, driving all pistons to rise synchronously, and the fluid in the barrel will be sucked into the measuring cylinder by the feed pipe, and the amount of fluid in the measuring cylinder can be controlled by controlling the lifting height of the lifting seat; when the stirring device needs to be loaded, the first control valve is closed, the second control valve is opened, the servo electric cylinder pushes the lifting seat to descend at a uniform and stable speed, driving all pistons to descend synchronously, and the fluid in the measuring cylinder will be discharged through the discharge pipe.

[0008] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The present invention utilizes the lifting effect of the lifting seat to drive all pistons to lift synchronously, and with the opening and closing of the first control valve and the second control valve, different fluids can be sucked into the measuring cylinder or the fluid in the measuring cylinder can be discharged. The ratio of various fluid components is fixed and precise, and the quantitative amount of the fluid components is controlled by the stroke of the servo electric cylinder. The control method is simple and reliable, the overall cost is relatively low, and it is easy to maintain and debug. BRIEF DESCRIPTION OF THE DRAWINGS
