Description

Technical Field

[0001] The utility model relates to the technical field of coating, in particular to a two-component flow box. Background Art

[0002] In the coating industry, paint, as one of the key materials, plays a vital role in the quality and performance of the workpiece surface.

[0003] Two-component paints have gradually become the mainstream choice of the industry due to their excellent physical and chemical properties and wide adaptability. Two-component paints are usually composed of two parts: a base agent and a curing agent. The two need to be accurately proportioned and mixed before use to ensure the quality and performance of the coating.

[0004] However, in the existing painting process, there are often some problems in the mixing and proportioning of two-component paints. First, the traditional mixing method often relies on manual operation or simple mechanical equipment, which makes it difficult to ensure the accuracy of the proportion and the uniformity of the mixing. When it is necessary to switch different components or adjust the proportion, the existing equipment often requires cumbersome adjustments and operations, which not only increases the difficulty of operation, but also reduces production efficiency.

[0005] In addition, in order to form different colors or meet specific performance requirements, it is necessary to frequently switch between different components of paint. However, under existing technical conditions, the switching process often takes a long time, and it is difficult to ensure the accuracy and stability of the switching. This not only affects production efficiency, but may also cause fluctuations in coating quality and performance.

[0006] When faced with these problems, the existing approach is often to increase manual intervention and inspection, or use more complex mechanical equipment for proportioning and mixing. However, these methods cannot fundamentally solve the problem, but may increase production costs and maintenance difficulties. For example, increasing manual intervention may lead to human errors, while complex mechanical equipment requires higher maintenance costs and time.

[0007] Therefore, how to achieve uniform mixing of two-component paints and rapid switching of different components has become an issue to be solved by the present invention. Utility Model Content

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1 —2. In the embodiment of the utility model, a two-component flow box includes a box body 1, a fluid conveying mechanism 2, a static mixer 3, a mixed paint pipe 4 and a spray gun 5; the box body 1 is provided with two fluid conveying mechanisms 2, the fluid conveying mechanism 2 includes a paint supply mechanism 6, a flow meter 7 and a proportioning valve 8; the number of the paint supply mechanisms 6 is more than two, and the paint supply mechanism 6 includes a paint supply pipe 9 and a paint supply valve 10; the paint supply pipe 9 is connected to the flow meter 7 through the paint supply valve 10, and the flow meter 7 is connected to the static mixer 3 through the proportioning valve 8, so as to facilitate mixing through the static mixer 3, and utilize the static mixer 3 itself in the prior art to generate diversion, cross mixing and reverse vortex through the flow of the fluid itself, so that different fluids can be quickly dispersed and mixed, with high mixing efficiency, which is conducive to instantaneous mixing, and its efficiency is even as high as 90-95%, so as to achieve a mixing effect, and after mixing, it flows to the spray gun 5 through the mixed paint pipe 4.

[0031] The two-component flow box also includes a cleaning mechanism, which includes a solvent cleaning pipeline 11 and a cleaning valve 12. The solvent cleaning pipeline 11 is connected to the paint supply pipe 9 through the cleaning valve 12, wherein the specific position where the solvent cleaning pipeline 11 is connected to the paint supply pipe 9 through the cleaning valve 12 is between the paint supply valve 10 and the flow meter 7 on the paint supply pipe 9 and close to the paint supply valve, so that in this way, only the second half of the paint supply pipe 9 is cleaned with solvent, and the front half of the paint supply pipe 9 does not need to be taken out of the paint bucket or disconnected from the connected paint source. When the paint supply pipe 9 can be taken out of the paint bucket, the solvent for cleaning can be probed into the front half of the paint supply pipe 9 or the solvent source can be connected to spray the cleaning solvent through the spray gun 5 to achieve overall flow channel cleaning of the entire paint supply pipe 9 and its related components. These are all extended implementation methods that can be known to ordinary technicians in this field.

[0032] There are three paint supply mechanisms 6, the cleaning mechanism is located at the bottom of the box body 1, and there are two fluid conveying mechanisms 2 including a first fluid conveying mechanism 2 and a second fluid conveying mechanism 2. The first fluid conveying mechanism 2 is a main fluid conveying mechanism 2, and the second fluid conveying mechanism 2 is a curing agent fluid conveying mechanism 2. The connection is through a pipeline, and the flowmeter 7 is an ultrasonic flowmeter 7. The two fluid conveying mechanisms 2 are fixedly connected to the box body 1 by means of snap-on and / or bolted connections.

[0033] Embodiment 1:

[0034] The present embodiment provides a two-component flow box, which is designed to achieve efficient, accurate proportioning and mixing of two-component paints while ensuring rapid response and flexibility in the production process.

[0035] Specifically, the two-component flow box includes a box body 1, two fluid conveying mechanisms 2 (i.e., the first fluid conveying mechanism 2 is a main agent fluid conveying mechanism, and the second fluid conveying mechanism 2 is a curing agent fluid conveying mechanism), a static mixer 3, a mixed paint pipe 4 and a spray gun 5. Each fluid conveying mechanism 2 is equipped with a paint supply mechanism 6, a flow meter 7 and a proportioning valve 8 to achieve precise flow control and proportioning. The paint supply mechanism 6 is designed to include three paint supply pipes 9 and corresponding paint supply valves 10. Such a design provides redundancy and flexibility to meet different production needs.

[0036] In practical applications, the configuration of the paint supply pipe 9 and the paint supply valve 10 is not only to increase the paint supply. When a paint supply pipe 9 has unstable flow due to blockage, wear or other reasons, it can be quickly switched to other spare paint supply pipes 9 to ensure the continuous operation of the production line. In addition, the design of multiple paint supply pipes 9 also allows the use of paints of different viscosities or colors at the same time, thereby achieving the diversification of coatings without replacing the entire paint supply system.

[0037] For example, in an automobile painting production line, different colors and properties of paint may be used for different parts or different models. By controlling the switches of different paint supply valves 10, the paint supply pipe 9 can be easily switched to achieve the purpose of quickly changing the coating material. This not only reduces the downtime of the production line, but also improves production efficiency and product quality.

[0038] The function of the flow meter 7 is not only to accurately measure the amount of paint flowing through to achieve accurate proportioning, but also to monitor the flow changes in real time to provide data support for the control and adjustment of the production process. The proportioning valve 8 dynamically adjusts the opening according to the feedback of the flow meter 7 to ensure that the main agent and the curing agent are always mixed in the preset optimal ratio.

[0039] In addition, the cleaning mechanism exists to ensure that the paint supply pipe 9 and other related parts can be cleaned quickly and thoroughly when switching different components or ending production, so as to prevent paint residue from affecting the next production. By connecting the solvent cleaning pipeline 11 to a specific position of the paint supply pipe 9 (i.e., between the paint supply valve 10 and the flow meter 7), this embodiment provides an efficient cleaning solution, which not only ensures the cleaning effect, but also reduces the consumption of cleaning agents and time.

[0040] In summary, the two-component flow box provided in this embodiment not only realizes the precise proportioning and uniform mixing of two-component paints, but also meets the complex and changeable coating production requirements through flexible paint supply pipe switching and efficient cleaning mechanism.

[0041] Embodiment 2:

[0042] This embodiment provides an optimization solution for a two-component flow box, which is particularly suitable for painting scenarios that require frequent switching of different component paints to form different colors or meet specific performance requirements.

[0043] Similar to Example 1, the two-component flow box of this embodiment also includes a box body 1, a fluid delivery mechanism 2, a static mixer 3, a mixed paint pipe 4 and a spray gun 5. Two fluid delivery mechanisms 2 are provided, which are used to deliver the main agent and the curing agent respectively, and each fluid delivery mechanism 2 is equipped with a paint supply mechanism 6, a flow meter 7 and a proportioning valve 8. The number of paint supply mechanisms 6 is set to more than two to meet the switching requirements of more components.

[0044] The paint supply mechanism 6 is the key improvement part of this embodiment. Each paint supply mechanism 6 includes a paint supply tube 9 and a paint supply valve 10, and one end of the paint supply tube 9 can be inserted into a paint bucket of different colors. By starting the paint supply valves 10 of different colors, raw materials of corresponding colors can be extracted for mutual matching. This design makes it possible to achieve fast and accurate component switching by simply inserting the paint supply tube 9 into the paint bucket of the corresponding color and controlling the switch state of the corresponding paint supply valve 10 when frequent switching of different component paints is required.

[0045] In addition, in order to further improve the switching efficiency and ensure the cleanliness of the switching, the two-component flow box of this embodiment is also equipped with a cleaning mechanism. The cleaning mechanism includes a solvent cleaning pipeline 11 and a cleaning valve 12. The solvent cleaning pipeline 11 is connected to various parts of the fluid conveying mechanism 2 through the cleaning valve 12. When it is necessary to switch different colors, the cleaning valve 12 can be opened to allow the water source or solvent in the cleaning pipeline to flow to the flow meter 7, the proportioning valve 8, the static mixer 3, the mixing paint pipe 4 and the spray gun 5 in turn, so as to thoroughly clean these components. After cleaning, there is no residue or pollution on the components, which ensures that they can quickly reach a clean state when switching next time, effectively avoiding the problems of color confusion and performance fluctuations.

[0046] In general, the two-component flow box provided in this embodiment realizes efficient, accurate and clean switching when frequently switching between different components of paint by increasing the number of paint supply mechanisms 6 and optimizing the design of the cleaning mechanism. This improvement not only improves production efficiency, but also ensures the stability and consistency of the quality and performance of the coating. At the same time, the two-component flow box also has the advantages of simple structure, convenient operation, low maintenance cost, etc., and has high practical value and market prospects.
