Abstract
Description
Technical Field
[0001] This utility model relates to the field of intelligent color matching technology, specifically to a reversing valve for rapid material extraction and an intelligent color matching machine. Background Technology
[0002] Paint is a coating applied to the surface of an object to be protected or decorated, forming a continuous film that adheres firmly to the object. It is usually a viscous liquid made of resin, oil, or emulsion as the main component, with added pigments, fillers, and appropriate additives, and formulated with organic solvents or water. It has good applications in the automotive, construction, furniture, printing, textile, and pigment industries.
[0003] Paint typically requires mixing before use, meaning multiple colors of paint are mixed in a specific ratio to obtain the desired color. However, this requires extremely high accuracy in the mixing amount of each color. Currently, most paint mixing is done using a color mixing machine. For example, a high-precision reversing ball valve and intelligent color mixing machine disclosed in publication number CN222502762U switches between pumping and discharging states by rotating an internal reversing valve. However, its feed pipe is a "Z"-shaped pipe. When the paint in the storage tank enters the valve core pipe through the feed pipe, the paint needs to flow through multiple bends. Since the paint is a highly viscous liquid, it is blocked by the inner wall of the bends in the feed pipe during pumping, which increases the suction force required by the pump, making pumping more difficult and slower, and unable to achieve rapid pumping. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a reversing valve for rapid material extraction and an intelligent color mixing machine.
[0005] This application discloses a rapid material extraction reversing valve comprising: a valve body assembly and a valve core assembly. The valve body assembly includes a valve core pipe fitting and an inlet pipe fitting and a pressure pump pipe fitting, which are respectively connected to the valve core pipe fitting. The valve core assembly has a rotating surface and an inlet surface. The valve core assembly is rotatably mounted on the valve core pipe fitting, and the rotating surface abuts against the pipe port of the pressure pump pipe fitting and the outlet of the valve core pipe fitting, respectively. The valve core assembly has a material extraction channel and a material discharge channel. The material extraction channel has a first port and a second port, which are respectively located on the rotating surface and the inlet surface. The inlet pipe fitting has a straight inlet channel, one end of which is connected to a storage cylinder. In the material extraction state, the first port is connected to the pipe port of the pressure pump pipe fitting, and the second port is directly opposite the other end of the straight inlet channel. The material discharge channel is offset from the outlet.
[0006] Preferably, the valve core assembly is a ball valve.
[0007] Preferably, the rotating surface of the valve core assembly is in contact with the inner wall of the valve core pipe fitting.
[0008] Preferably, the rapid feeding reversing valve also includes a sealing assembly, which is sealed between the rotating surface and the discharge port.
[0009] Preferably, there are two sealing components, one of which is sealed between the rotating surface and the discharge port, and the other is sealed between the rotating surface and the pipe opening of the pressure pump pipe fitting.
[0010] Preferably, the valve core pipe fitting includes a valve core pipe and a chassis. The chassis is detachably installed at the bottom of the valve core pipe, and the discharge port is opened on the chassis. The valve core pipe is connected to the feed pipe fitting and the pressure pump pipe fitting respectively, and the valve core assembly is rotatably located inside the valve core pipe.
[0011] Preferably, the valve core pipe fitting also includes multiple fixing parts, the chassis has multiple first mounting holes, and the bottom of the valve core pipe has multiple second mounting holes corresponding to the positions of the multiple first mounting holes. The multiple fixing parts pass through the multiple first mounting holes and the multiple second mounting holes respectively, so that the chassis can be detachably installed on the bottom of the valve core pipe.
[0012] Preferably, the quick-drawing directional valve also includes a throttle assembly, with a groove on the side of the valve core assembly facing the throttle assembly, one end of the throttle assembly being embedded in the groove, and the other end of the throttle assembly extending outward after passing through the valve core pipe fitting.
[0013] Preferably, the discharge channel has a third port and a fourth port, which are respectively located on the rotating surface; the valve core assembly also has a discharge state, with the third port and the fourth port respectively connected to the pipe port and discharge port of the pressure pump pipe fitting.
[0014] This application also discloses an intelligent color mixing machine, including a reversing valve for rapid material extraction.
[0015] The beneficial effects of this application are as follows: by setting up a straight feeding channel, the paint in the storage tank can flow directly into the valve core pipe fitting along the straight feeding channel, avoiding problems such as slow material extraction and large required extraction force caused by the tortuous flow path of the paint. At the same time, since the second port is directly opposite the other end of the straight feeding channel, compared with the traditional structure where the second port and the feeding pipe fitting are partially staggered, the paint can flow directly into the extraction channel without obstruction, which can further reduce the tortuous flow path of the paint and further improve the extraction speed.

[0031] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0032] Reference Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the reversing valve for rapid material extraction in the embodiment. Figure 2 The diagram shows a cross-sectional view of the rapid material extraction reversing valve in this embodiment. The rapid material extraction reversing valve in this embodiment includes a valve body assembly 1 and a valve core assembly 2. The valve body assembly 1 includes a valve core pipe fitting 11 and an inlet pipe fitting 12 and a pressure pump pipe fitting 13, which are respectively connected to the valve core pipe fitting 11. The valve core assembly 2 has a rotating surface 21 and an inlet surface 22. The valve core assembly 2 is rotatably mounted on the valve core pipe fitting 11. The rotating surface 21 abuts against the pipe opening of the pressure pump pipe fitting 13 and the outlet 1121 of the valve core pipe fitting 11. The valve core assembly 2 has a material extraction channel 23 and an outlet channel 24. The material extraction channel 23 has a first port 231 and a second port 232. The first port 231 and the second port 232 are respectively opened on the rotating surface 21 and the inlet surface 22. The inlet pipe fitting 12 has a straight inlet channel 121, one end of which is connected to a storage cylinder. In the material feeding state, the first port 231 is connected to the pipe opening of the pressure pump pipe fitting 13, the second port 232 is directly opposite the other end of the straight feed channel 121, and the discharge channel 24 is offset from the discharge port 1121.
[0033] Reference Figures 3-5 , Figure 3 This is a schematic diagram of the reversing valve and material pump for rapid material extraction in the embodiment. Figure 4This is a cross-sectional view of the reversing valve and the feed pump used for rapid material extraction in the embodiment. Figure 5 This is a cross-sectional view of the valve core assembly in the material extraction state in this embodiment. The rapid material extraction reversing valve in this embodiment is used to quantitatively discharge the paint and then mix it to achieve color matching. Specifically, it can be applied to color matching of paints such as automotive touch-up paint and wall painting. The rapid material extraction reversing valve in this embodiment is used in an intelligent color matching machine, and the specific description of the intelligent color matching machine composed of the rapid material extraction reversing valve in this embodiment is also introduced in this embodiment. In specific application, the intelligent color matching machine includes multiple rapid material extraction reversing valves, multiple storage tanks, and multiple material pumps 100. Each rapid material extraction reversing valve is respectively matched with a storage tank and a material pump. One end of each feed pipe 12 is connected to a storage tank. The multiple storage tanks respectively contain multiple different colors of paint, and the multiple material pumps are respectively connected to multiple pressure pump pipes 13. In the pumping state, the material pump 100 rises within the pressure pump pipe fitting 13, drawing the paint from the storage tank into the pressure pump pipe fitting 13 after passing through the feed pipe fitting 12, the valve core pipe fitting 11, and the extraction channel 23. Through the straight feed channel 121, the paint in the storage tank can flow directly into the valve core pipe fitting 11 along the straight feed channel 121, avoiding problems such as slow extraction and high required pumping force caused by the tortuous flow path of the paint. Furthermore, since the second port 232 is directly opposite the other end of the straight feed channel 121, compared to the traditional structure where the second port 232 and the feed pipe fitting 12 are partially offset, the paint can flow directly into the extraction channel 23 without obstruction, further reducing the tortuous flow path of the paint and further improving the extraction speed.
[0034] Reference Figures 6-7 , Figure 6 This is a schematic diagram of the valve core assembly in the embodiment. Figure 7 This is a perspective view of the valve core assembly in the embodiment. Figure 6The diagram shows a cross-sectional view of the valve core assembly in the discharge state in the embodiment. Preferably, the discharge channel 24 has a third port 241 and a fourth port 242, which are respectively located on the rotating surface 21. The valve core assembly 2 also has a discharge state, where the third port 241 and the fourth port 242 are respectively connected to the pipe opening and the discharge port 1121 of the pressure pump pipe fitting 13. In specific applications, when the amount of coating material in the pressure pump pipe fitting 13 reaches a certain level and discharge is required, the pump descends and forces the coating material in the pressure pump pipe fitting 13 to be discharged. The coating material is discharged sequentially through the pipe opening, the third port 241, the discharge channel 24, the fourth port 242, and the discharge port 1121 of the pressure pump pipe fitting 13. Specifically, the material pump includes a pressure piston and a lifting drive module. One end of the pressure piston is movably disposed within the pressure pump pipe component 13, and the other end of the pressure piston extends outward after passing through the top of the pressure pump pipe component 13, and connects to the drive end of the lifting drive module. The pressure pump pipe component 13 includes a pressure pump pipe and a pressure barrel. The pressure pump pipe is connected to the valve core pipe component 11, and the pressure barrel is connected to the pressure pump pipe. One end of the pressure piston is movably disposed within the pressure barrel. The pressure pump pipe and the pressure barrel contain coating material. The feed pipe component 12 is the feed pipe.
[0035] Rereference Figures 6-7 Preferably, the valve core assembly 2 is a ball valve. In specific applications, in this embodiment, the feeding channel 23 and the discharging channel 24 are not interconnected. It can be understood that the discharging channel 24 passes through the center of the ball in the valve core assembly 2 and is straight. When discharging, the paint in the discharging channel 24 does not flow to the feeding channel 23. That is, the feeding channel 23 and the discharging channel 24 are independent flow channels. Compared with the traditional valve core with interconnected channels, this embodiment can ensure that the two channels do not affect each other when the valve core assembly 2 is working, which facilitates the control of the paint discharge amount, ensures the controllability of the paint discharge amount, and improves the accuracy of the discharge. When discharging, the paint it presses out comes entirely from the pressure pump pipe component 13, and the paint in the pressure pump pipe component 13 only flows to the discharging channel 24. That is, the amount of paint reduction in the pressure pump pipe component 13 is the actual discharge amount, further improving the accuracy of paint discharge amount control. Furthermore, the material extraction channel 23 includes a first material extraction channel and a second material extraction channel that are perpendicular to and connected to each other. One end of the first material extraction channel is a first port 231, and the other end of the first material extraction channel is connected to one end of the second material extraction channel. The other end of the second material extraction channel is a second port 232. It can be understood that the feed surface 22 of the valve core assembly 2 is a plane, and the second port 232 is not located at the center of the feed surface 22. This allows the discharge channel 24 to completely avoid the material extraction channel 23, and also allows for a further increase in the diameter of the first port 231 and the second port 232, thereby increasing the volume of the material extraction channel 23 and increasing the flow rate of the coating per unit time during the material extraction process, so as to achieve rapid material extraction.
[0036] Rereference Figure 2 Preferably, the rotating surface 21 of the valve core assembly 2 is in contact with the inner wall of the valve core pipe fitting 11. In practical applications, there is a gap between the feed surface 22 and the feed pipe fitting 12, which is the internal space of the valve core pipe fitting 11. The rotating surface 21 of the valve core assembly 2 is in contact with the inner wall of the valve core pipe fitting 11. That is to say, in the pumping state, the paint in the storage tank is first pumped into the feed pipe fitting 11, and then into the valve core pipe fitting 11 between the feed surface 22 and the feed pipe fitting 12. Then it directly enters the pumping channel 23 through the second port 232 and passes through the first port 231 and the pipe opening of the feed pipe fitting 12 before entering the feed pipe fitting 12. Since the rotating surface 21 of the valve core assembly 2 is in contact with the inner wall of the valve core pipe fitting 11, the paint will not flow between the rotating surface 21 and the inner wall of the valve core pipe fitting 11 after entering the valve core pipe fitting 11 between the feed surface 22 and the feed pipe fitting 12, nor will it flow into the discharge channel 24. This reduces the force required to pump the paint and improves the pumping efficiency.
[0037] Rereference Figure 2 Preferably, the rapid material extraction reversing valve also includes a sealing component 3, which is sealed between the rotating surface 21 and the discharge port 1121. The sealing component 3 seals the gap between the rotating surface 21 and the discharge port 1121, ensuring that the rotating surface 21 and the sealing component 3 completely seal the discharge port 1121, preventing leakage of coating material from the gap, improving sealing performance, and enhancing the accuracy of material discharge. Furthermore, there are two sealing components 3: one sealing component 3 is sealed between the rotating surface 21 and the discharge port 1121, and the other sealing component 3 is sealed between the rotating surface 21 and the pipe opening of the pump pipe fitting 13. Another sealing component 3 seals the gap between the rotating surface 21 and the pipe opening of the pump pipe fitting 13, ensuring that the rotating surface 21 and the sealing component 3 can completely seal and block the pipe opening of the pump pipe fitting 13, preventing paint leakage from the gap between the rotating surface 21 and the pipe opening of the pump pipe fitting 13, improving sealing performance and improving the accuracy of material discharge. Specifically, the sealing component 3 is a sealing rubber ring.
[0038] Reference Figure 9 , Figure 9This is another structural schematic diagram of the rapid material extraction reversing valve in the embodiment. Preferably, the valve core pipe component 11 includes a valve core pipe 111 and a base plate 112. The base plate 112 is detachably installed at the bottom of the valve core pipe 111, and the discharge port 1121 is opened at the base plate 112. The valve core pipe 111 is connected to the feed pipe component 12 and the pressure pump pipe component 13 respectively. The valve core assembly 2 is rotatably disposed inside the valve core pipe 111. In specific applications, since the base plate 112 is detachably installed at the bottom of the valve core pipe 111, when the coating inside the valve core pipe component 11 solidifies and becomes blocked, the base plate 112 can be disassembled to expose the interior of the valve core pipe 111 for easy cleaning by the operator, thus extending its service life. Furthermore, the rapid material extraction reversing valve also includes a rotary handle assembly 4. A groove 25 is opened on the side of the valve core assembly 2 facing the rotary handle assembly 4. One end of the rotary handle assembly 4 is embedded in the groove 25, and the other end of the rotary handle assembly 4 extends outward after passing through the valve core pipe component 11. In practical applications, under normal use, rotating the other end of the handle assembly 4 will drive the valve core assembly 2 to rotate, thereby switching the valve core assembly 2 between the feeding and discharging states. When cleaning the valve core pipe fitting 11 or the valve core assembly 2 is required, the chassis 112 is first disassembled. Rotating the handle assembly 4 drives the valve core assembly 2 to rotate, so that the opening on the side of the slide groove 25 faces the bottom of the valve core pipe 111. In this way, the slide groove 25 of the valve core assembly 2 can slide relative to one end of the handle assembly 4, thereby removing the valve core assembly 2 from the valve core pipe 111 for further cleaning, and further cleaning the inside of the valve core pipe 111, improving the cleaning effect. Specifically, the handle assembly 4 is a rotating handle, the shape of one end of which is adapted to the slide groove 25.
[0039] Rereference Figure 9Preferably, the valve core pipe fitting 11 further includes multiple fixing parts. The chassis 112 has multiple first mounting holes 1122, and the bottom of the valve core pipe 111 has multiple second mounting holes corresponding to the positions of the multiple first mounting holes 1122. The multiple fixing parts pass through the multiple first mounting holes 1122 and the multiple second mounting holes respectively, so that the chassis 112 can be detachably installed on the bottom of the valve core pipe 111. In specific applications, the multiple first mounting holes 1122 are arranged in a ring around the bottom of the valve core pipe 111 at intervals. The fixing parts are fixing screws. By fixing the fixing parts through the second mounting holes and fixing them into the first mounting holes 1122 at the bottom of the valve core pipe 111, the chassis 112 can be fixed to the bottom of the valve core pipe 111. The chassis 112 can be disassembled by unscrewing the fixing parts. It should be noted that the method of fixing the chassis 112 with fixing parts is not only convenient for installation and disassembly, but also more convenient than the traditional method of fixing the valve core pipe 111 and the chassis 112 with screws. In terms of the structure, the bottom height of the chassis 112 in this embodiment can be kept consistent, while the traditional screw-fixed structure is prone to one side being higher than the other. In this case, it is only necessary to rotate the fixing part to make the depth of the multiple fixing parts fixed in the second mounting hole consistent, so as to ensure that the chassis 112 is horizontal relative to the bottom of the valve core pipe 111. The adjustment is easy, and the sealing between the valve core pipe 111 and the chassis 112 is improved. At the same time, the horizontal chassis 112 can also improve the sealing between the rotating surface 21 and the discharge port 1121, further improving the discharge accuracy.
[0040] In summary, by setting up the straight feed channel 121, the paint in the storage tank can flow directly into the valve core pipe fitting 11 along the straight feed channel 121, avoiding problems such as slow material extraction and large required extraction force caused by the tortuous flow path of the paint. At the same time, since the second port 232 is directly opposite the other end of the straight feed channel 121, compared with the traditional structure where the second port 232 and the feed pipe fitting 12 are partially staggered, the paint can flow directly into the extraction channel 23 without obstruction, which can further reduce the tortuous flow path of the paint and further improve the extraction speed.
