Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of color mixing machines, and in particular to a reversing ball valve and an intelligent color mixing machine. Background Art
[0002] Paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. It is usually a viscous liquid made of resin, oil, or emulsion, with pigments, fillers and corresponding additives added, and prepared with organic solvents or water. It has good application scenarios in the automotive, construction, and furniture fields.
[0003] In the field of automobile repainting, it is often necessary to match the corresponding color of paint according to the color of the car paint, and colored paint often needs to be mixed with a variety of different colors of paint in a certain proportion to obtain, and the accuracy of the mixing amount of each color paint is extremely high. Nowadays, most of the paint coloring work is done by using a color mixing machine, which outputs corresponding different colors of paint according to the mixing ratio by setting up multiple color mixing mechanisms, and then mixes these paints to obtain the required color of paint, but the existing color mixing mechanism is only provided with one discharge port, which is opened or closed by the internal reversing valve. Whether the color mixing mechanism is for large flow rate fast discharge or small flow rate precise discharge, it is discharged from the discharge port. The quantitative discharge is only achieved by quantitative extrusion by a quantitative pump, and the discharge control accuracy is low. In particular, when performing small flow rate precise discharge, the color of the mixed paint often deviates due to inaccurate discharge amount, which seriously affects the quality of the paint.
[0004] Most existing color mixing machines include a paint bucket, a paint quantitative injection pump and a three-way reversing valve. The three-way reversing valve is connected to the paint bucket and the paint quantitative injection pump respectively. The paint is extracted from the paint bucket through the paint quantitative injection pump and stored in the paint quantitative injection pump and the three-way reversing valve. Then the three-way reversing valve rotates a certain angle so that the through hole of the three-way reversing valve is connected to the discharge port. The paint quantitative injection pump pushes the paint to achieve quantitative discharge of the paint from the discharge port. However, most of the three-way reversing valves nowadays have complex structures, and if they are idle for a period of time, the paint inside them often solidifies, which causes the valve core to be blocked. At this time, the entire three-way reversing valve needs to be replaced or cleaned. Disassembly, maintenance, cleaning and replacement of the three-way reversing valve require a lot of time and labor costs, which seriously affects the product life and production efficiency.

[0029] In order to further understand the application content, features and effects of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.
[0030] Reference Figure 1-3 , Figure 1 It is a structural schematic diagram of the reversing ball valve in the embodiment, Figure 2 This is a bottom view of the reversing ball valve in the embodiment. Figure 3: is a cross-sectional view of the reversing ball valve in the embodiment. The reversing ball valve in this embodiment includes a feed pipeline member 1, a pressure pump pipeline member 2 and a valve core pipeline member 3. The pressure pump pipeline member 2 is connected to the feed pipeline member 1. The valve core pipeline member 3 includes a valve core pipeline 31, a ball valve 32 and a chassis 33. The ball valve 32 is rotatably arranged in the valve core pipeline 31. One end of the valve core pipeline 31 is connected to the feed pipeline member 1. The chassis 33 is detachably installed on the other end of the valve core pipeline 31. The chassis 33 is provided with a discharge port 331, and the discharge port 331 is connected to the valve core pipeline 31. The ball valve 32 is located between the pipeline port and the discharge port 331 of the feed pipeline member 1. The ball valve 32 has a circulation channel 321 and a plurality of through ports 322 connected to the circulation channel 321. When the ball valve 32 is in the first rotation position, it is in the feeding state. One through port 322 is connected to the feed pipeline member 1, and the other through ports 322 are staggered with the discharge port 331. When the ball valve 32 is in the second rotation position, it is in the discharging state, one of its openings 322 is communicated with the feed pipe member 1 , and the other opening 322 is communicated with the discharging port 331 .
[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 , Figure 6The figure is a schematic diagram of the structure of the intelligent color mixing machine in the embodiment. The reversing ball valve in the embodiment is used in combination with the paint container 100 and the metering pump 101, and the specific description of the intelligent color mixing machine composed of the reversing ball valve in the embodiment, the paint container 100 and the metering pump 101 is also introduced in the embodiment. The embodiment is used to mix the paint after quantitative discharging, and can be applied to the color mixing of paint such as car touch-up paint and wall painting. Specifically, the intelligent color mixing machine in the embodiment includes a reversing ball valve, a paint container 100 and a metering pump 101, and the material container and the metering pump 101 are connected to the reversing ball valve respectively. In the standby state, one of the ports 322 is connected to the feed pipe 1, and the other ports 322 are staggered with the discharge port 331. The metering pump 101 repeats the suction and pressure action, so that the paint flows back and forth in the pressure pump pipe 2, the valve core pipe 31 and the ball valve 32. In specific application, the intelligent color mixing machine in this embodiment is in standby state, that is, when no discharge work is performed, the port 322 is staggered with the discharge port 331, the discharge port 331 is in a closed state, one of the ports is connected to the feed pipe member 1, and the metering pump 101 is automatically turned on and works at a certain interval, that is, after the preset time is reached, the metering pump 101 starts to pump material, the paint is pumped out of the paint container 100, and the paint flows through the feed pipe member 1, the pressure pump pipe member 2, the port 322, the circulation channel 321 and the valve core pipe 31, and then the metering pump 101 pushes the feed The paint in the pipeline 1, the pressure pump pipeline 2, the circulation channel 321 and the valve core pipeline 31 is pressed back to the paint container 100, and this is repeated several times, so that the paint in the feed pipeline 1, the pressure pump pipeline 2, the circulation channel 321 and the valve core pipeline 31 circulates continuously, achieving the effect of the paint reflux moisturizing flow channel, and avoiding the situation where the paint remaining inside the intelligent color mixing machine solidifies and causes blockage inside the flow channel when the intelligent color mixing machine is not discharging. That is, the paint reflux moisturizing flow channel structure is formed by the metering pump 101 and the reversing ball valve, which effectively reduces the frequency of daily maintenance and extends the service life of the product. The metering pump 101 in this embodiment is a prior art, which has a timing controller. After a preset time, the metering pump 101 can be driven regularly to perform the process of the paint reflux moisturizing flow channel in the standby state of the intelligent color mixing machine.
[0032] Re-reference Figure 1-3Preferably, the chassis 33 is provided with a plurality of mounting holes, and the valve core pipeline member 3 further includes a plurality of fixing parts 35, and the plurality of fixing parts 35 are connected to the valve core pipeline 31 after passing through the plurality of mounting holes respectively, so that the valve core pipeline 31 and the chassis 33 are detachably connected. In specific applications, the fixing part 35 is a fixing screw, and the chassis 33 can be fixed to the valve core pipeline 31 by passing the fixing screw through the mounting hole and fixing it on the valve core pipeline 31. When the parts inside the valve core pipeline 31 are damaged and need maintenance or replacement, the valve core pipeline 31 can be separated from the chassis 33 by simply unscrewing the fixing screw, so as to facilitate workers to repair or clean the inside of the valve core pipeline 31. Specifically, in this embodiment, the number of mounting holes and fixing screws are both four, and the four mounting holes are arranged at intervals at the bottom of the chassis 33 in sequence, and the four fixing screws are arranged in the four mounting holes correspondingly, so as to ensure that the chassis 33 and the valve core pipeline 31 are stably connected.
[0033] Refer to Figure 4 , Figure 4 3 is a schematic diagram of the structure of the ball valve and the rotating shaft in the embodiment. Preferably, the valve core pipeline member 3 also includes a rotating shaft 34, one end of which is clamped with the ball valve 32, and the other end passes through the valve core pipeline 31 and extends to the outside. In specific application, the other end of the rotating shaft 34 is provided with a rotating handle for workers to rotate. The rotating shaft 34 is located on the rotating center axis of the ball valve 32 to ensure the accuracy of rotating the ball valve 32 by the rotating shaft 34. Specifically, a strip groove 323 is provided on the side of the ball valve 32 close to the rotating shaft 34, and the rotating shaft 34 is clamped in the strip groove 323. After the chassis 33 is disassembled, the rotating shaft 34 is rotated to drive the ball valve 32 to rotate synchronously until the strip groove 323 rotates to a position perpendicular to the chassis 33. At this time, the ball valve 32 slides relative to the rotating shaft 34 along the length direction of the strip groove 323, that is, the ball valve 32 is separated from the rotating shaft 34, and the ball valve 32 can be taken out of the valve core pipeline 31, which is convenient for the subsequent maintenance of the parts inside the valve core pipeline 31.
[0034] Re-reference Figure 1-4Preferably, a sealing member 36 is provided between the ball valve 32 and the pipe opening of the feed pipe member 1 , and between the ball valve 32 and the discharge port 331 . The two sealing members 36 are both in close contact with the ball valve 32, which can effectively improve the sealing performance between the ball valve 32 and the feed pipeline member 1. When the through port 322 is offset from the feed pipeline member 1, the sealing member 36 seals the connection between the ball valve 32 and the feed pipeline member 1 to prevent the paint from escaping from the edge of the ball valve 32 into or out of the feed pipeline member 1, thereby causing inaccurate feed amount. Similarly, when the two through ports 322 are respectively connected to the feed pipeline member 1 and the discharge port 331 for discharge, it is ensured that the paint can only flow to the discharge port through the flow channel 321 in the ball valve 32 for discharge, and the paint is prevented from escaping from other positions, causing the stroke output by the metering pump 101 to be inconsistent with the actual discharge amount, thereby improving the accuracy of discharge. In addition, the sealing member 36 can also prevent air from entering the valve core pipeline 31, and prevent air from mixing into the paint, resulting in the stroke output by the metering pump 101 being inconsistent with the actual discharge amount during discharge. Specifically, the sealing member 36 in this embodiment is a sealing rubber ring. Since the sealing rubber ring fits tightly with the ball valve 32, it is easy to cause wear after long-term use. At this time, the bottom plate 33 can be disassembled to replace the sealing rubber ring. After the ball valve 32 is taken out by rotating the rotating shaft 34, the sealing rubber ring provided at the pipeline opening of the feed pipeline member 1 can also be replaced. Of course, in other embodiments, the sealing member 36 can also be a sealing member such as a sealing disk or a sealing ring, which will not be described here.
[0035] Refer to Figure 5 , Figure 5 2 is a cross-sectional view of the ball valve in the embodiment. Preferably, there are three through ports 322, and the apertures of the three through ports 322 are different. In specific applications, in this embodiment, for easy distinction, the three through ports 322 are referred to as the first through port 3221, the second through port 3222, and the third through port 3223 in descending order of aperture. When the first opening 3221 is connected to the feed pipeline 1, the second opening 3222 and the third opening 3223 are staggered with the discharge port 331, that is, the discharge port 331 is in a closed state, and the metering pump 101 performs suction to draw the paint in the paint container 100 into the pressure pump pipeline 2. When the paint in the pressure pump pipeline 2 reaches a certain amount, the rotating shaft 34 drives the ball valve 32 to rotate synchronously until it rotates to the second opening 3222 to be connected to the feed pipeline 1 and the third opening 3223 to be connected to the discharge port 331. The metering pump 101 squeezes the paint out of the pressure pump pipeline 2, and the paint flows through the pressure pump pipeline 2, the feed pipeline 1, the second opening 3222, the circulation channel 321, the third opening 3223 in sequence, and is discharged through the discharge port 331. Specifically, three openings 322 are arranged around the ball valve 32. By rotating the rotating shaft 34 to drive the ball valve 32 to rotate, the first opening 3221, the second opening 3222 and the third opening 3223 can be connected to the feed pipe member 1 and the discharge port 331 in sequence.
[0036] Re-reference Figure 1-5 Preferably, an anti-wall hanging groove 332 is provided at the bottom of the chassis 33 along the rotation direction of the ball valve 32. In specific applications, since the ball valve 32 needs to be rotated during use to switch between different discharging states, and the ball valve 32 slides relative to the chassis 33 when it rotates, the paint at the discharge port 331 is easily hung on the chassis 33, thereby generating errors that affect the accuracy of discharging. By setting the anti-wall hanging groove 332, the ball valve 32 can protrude relative to the anti-wall hanging groove 332, and the groove wall of the anti-wall hanging groove 332 is arc-shaped, which reduces the adhesion between the paint and the groove wall of the anti-wall hanging groove 332, and prevents the paint from being hung on the chassis 33, thereby further improving the accuracy of discharging. It should be particularly noted that the discharge port 331 has a large diameter, so that a larger area of the ball valve 32 is exposed outside the valve core pipe 31. In this way, when discharging, the distance between the discharge port 331 and the bottom plate 33 is relatively far. Therefore, under the action of gravity, the paint is more easily gathered at the discharge port 331 instead of hanging on the bottom plate 33, thereby reducing the error caused by hanging on the wall and further improving the accuracy of discharging.
[0037] Re-reference Figure 1-5 Preferably, an opening 324 is provided at one end of the ball valve 32 away from the rotating shaft 34, and the opening 324 is respectively connected to the valve core pipeline 31 and the circulation channel 321, and is located on the rotation center axis of the ball valve 32. In specific application, when the intelligent color mixing machine is in standby mode and is ready to perform the paint reflux moisturizing flow channel process, the first opening 3221 is connected to the feed pipeline member 1, and the second opening 3222 and the third opening 3223 are both staggered from the discharge port 331. At this time, the discharge port 331 is closed. When the metering pump 101 is pumping, the paint in the valve core pipeline 31 flows into the ball valve 32 through the opening 324, and then flows into the feed pipeline member 1 through the first opening 3221. When the metering pump 101 is pressing the material, the paint in the feed pipe member 1 flows into the ball valve 32 through the first opening 3221, and then flows into the valve core pipe 31 through the opening 324. This is repeated several times, so that the paint in the feed pipe member 1, the pressure pump pipe member 2, the circulation channel 321 and the valve core pipe 31 circulates continuously, achieving the effect of paint reflux moisturizing the flow channel, avoiding the situation where the residual paint inside the intelligent color mixing machine solidifies and causes blockage in the flow channel when the discharge operation is not performed, so that the reversing ball valve can be used for a long time without the need for maintenance, and the paint inside will not solidify.
[0038] Preferably, the feed pipe member 1 is detachably connected to the paint container 100 and the metering pump 101. In specific applications, the feed pipe member 1 in this embodiment is a feed pipe, and the pressure pump pipe member 2 is a pressure pump pipe. The inner wall of one end of the feed pipe is provided with a thread, and the side wall of the paint container 100 is provided with a paint channel, and the outer surface of the paint channel is also provided with a thread. The feed pipe is screwed to the paint container 100, so that the feed pipe is connected to the paint container 100, ensuring that the feed pipe and the paint container 100 are firmly connected and have good sealing performance. At the same time, the screw connection also facilitates the separation of the feed pipe from the paint container 100, which is convenient for the later disassembly and maintenance of the reversing ball valve. The pressure pump pipe and the metering pump 101 are also screwed, which will not be repeated here.
[0039] Re-reference Figure 1-5 The intelligent color mixing machine in this embodiment has two states: working state and standby state. The standby state process is as follows: rotate the rotating shaft 34 so that the first port 3221 is connected to the feed pipe part 1, and the second port 3222 and the third port 3223 are staggered with the discharge port 331. At this time, the discharge port 331 is closed, and the intelligent color mixing machine is in standby state. In the standby state, the metering pump 101 will start regularly at intervals to perform the paint reflux moisturizing flow channel process, that is, the metering pump 101 sucks the material, and the paint in the paint container 100, the valve core pipe 31 and the ball valve 32 is sucked into the pressure pump pipe part 2. The paint in the valve core pipe 31 flows through the opening 324, the circulation channel 321, and the first port 3221 in turn and then flows into the pressure pump pipe part 2. Then the metering pump 101 presses the material, and presses the paint in the pressure pump pipe part 2 back into the paint container 100, the valve core pipe 31 and the ball valve 32. The pressure pump pipe part 2 flows through the first port 3221, the circulation channel 321, and the opening 324 in sequence and then flows into the valve core pipe 31. In this way, the quantitative pump 101 repeats the suction and pressure process several times, so that the paint in the valve core pipe 31 and the ball valve 32 forms a reflux, that is, a paint reflux moisturizing flow channel structure is formed, and a paint reflux moisturizing flow channel is realized, so that the paint in the flow channel can circulate, and avoid the situation that the paint remaining inside the intelligent color mixing machine solidifies and causes blockage inside the flow channel when the intelligent color mixing machine is not discharging, effectively reducing the frequency of daily maintenance and extending the service life of the product. At the same time, after the paint reflux moisturizing flow channel process, the paint in the valve core pipe 31 and the ball valve 32 can be kept full, and the air in the valve core pipe 31 and the ball valve 32 can also be effectively discharged through this process, ensuring the accuracy of the intelligent color mixing machine when it is discharging next time.
[0040] Re-reference Figure 1-5The working state of the intelligent color mixing machine in this embodiment is divided into a feeding state and a discharging state. In the feeding state: the first port 3221 is connected to the feeding pipeline 1, and the second port 3222 and the third port 3223 are staggered with the discharging port 331. At this time, the discharging port 331 is closed, and the metering pump 101 sucks the paint, and the paint in the paint container 100, the valve core pipeline 31 and the ball valve 32 is sucked into the pressure pump pipeline 2. When the paint in the pressure pump pipeline 2 reaches a certain amount, it enters the discharging state. In the discharging state: the second port 3222 is connected to the feeding pipeline 1, and the third port 3223 is connected to the discharging port 331. The metering pump 101 presses the paint, and the paint enters the circulation channel 321 through the second port 3222, and is discharged through the discharging port 331 after passing through the third port 3223.
[0041] To sum up, since the chassis is detachably connected to the valve core pipeline, when the ball valve or the valve core pipeline is blocked by paint solidification, the chassis can be quickly disassembled for cleaning and maintenance, thereby improving the convenience of daily maintenance. At the same time, the paint reflux moisturizing flow channel process can be carried out regularly in the standby state to ensure that the paint in the ball valve and the valve core pipeline can flow to play the role of moisturizing the flow channel, avoiding the long-term accumulation and solidification of the residual paint inside and causing blockage in the flow channel, effectively reducing the frequency of daily maintenance, extending the service life of the product, and effectively exhausting the air in the valve core pipeline and the ball valve, ensuring the accuracy of the intelligent color mixing machine's discharge when it performs the next discharge work.
[0042] The above is only the implementation mode of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
