Description

Technical Field

[0001] This utility model relates to the field of color matching devices, and in particular to a color matching device for advertising design that can accurately apply colors. Background Technology

[0002] With the rapid development of society and the economy, people's quality of life has significantly improved, and their pursuit of a higher quality of life has reached unprecedented heights. In today's dazzling array of goods in the market, advertising is becoming increasingly important in order to stand out from the fierce competition and attract consumers' attention. As the core element of advertising, the quality of advertising design directly affects the effectiveness of advertising and the sales volume of goods. In the process of advertising design, drawing is an indispensable and important tool. It transforms creativity into visual images through elements such as color and lines, thereby conveying the information and value of the product.

[0003] In existing technologies, especially in the field of advertising design and painting, the use of color is crucial. Different colored paints are often mixed from multiple primary color paints in specific proportions to ensure precise application. However, there are many problems in the paint mixing process. On the one hand, traditional color mixing methods mainly rely on manual filling, which makes it difficult to precisely control the amount of raw materials. Manual operation is easily affected by subjective factors and external environmental factors, such as the operator's experience, concentration, and the accuracy of measuring tools, leading to errors in the amount of filler. This error directly affects the final color of the paint, causing the mixed color to deviate from the design expectation, thus affecting the overall effect of the advertising design. On the other hand, paints used for painting, such as acrylic paints, have special physical properties. Acrylic paints become viscous or even solidify after prolonged storage or in low-temperature environments. In this state, the paint is difficult to flow, hindering the mixing and blending of various raw materials. Even if it is restored to fluidity through heating, it may still affect the performance and quality of the paint, resulting in unsatisfactory color mixing results. Utility Model Content

[0004] The main purpose of this utility model is to provide a color matching device for advertising design that can accurately apply color, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A color matching device for advertising design with precise color application includes a frame and a housing fixedly connected to the top surface of the frame.

The driven bevel gear is fixedly connected to the top end of the second rotating rod and meshes with the active bevel gear. The scraper is fixedly connected to the stirring shaft through several stirring rods.

[0007] In a preferred embodiment of this invention, the top surface of the support plate is fixedly equipped with several pigment tanks storing different colors of pigment in a horizontal array, and an electromagnetic flow valve is fixedly installed on the discharge port at the bottom of the pigment tank. The first pump body is fixedly installed at the bottom of the inner part of the housing, and a manifold is fixedly installed between the input end of the first pump body and the electromagnetic flow valve. A conveying pipe is fixedly installed on the output end of the first pump body. The color mixing tank is fixedly installed on the right side of the top surface of the support plate, and a conveying pipe is also fixedly installed between the side wall inlet of the color mixing tank and the output end of the first pump body. A discharge valve is fixedly installed at the bottom discharge port of the color mixing tank. The second pump body is also fixedly installed at the bottom of the inner part of the housing, and a connecting pipe is fixedly installed between the input end of the second pump body and the discharge valve. A discharge pipe extending out of the housing is fixedly installed on the output end of the second pump body.

[0008] As a preferred embodiment of this utility model, a set of symmetrical hydraulic cylinders are fixedly installed on the top surface of the support plate, and a sealing cover is fixedly installed on the output end of the symmetrical hydraulic cylinders. A set of symmetrical side plates are fixedly installed on the top surface of the sealing cover, and a first mounting hole is opened on the side wall of the side plate. A first bearing is fixedly installed in the hole of the first mounting hole. A plurality of second mounting holes corresponding to the pigment can and the color mixing can are also opened on the top surface of the sealing cover, and a second bearing is fixedly installed in the hole of the second mounting hole.

[0009] In a preferred embodiment of this invention, a first rotating rod is fixedly installed at each of the left and right ends of the rotating shaft, and the first rotating rod is fixedly installed together with the first bearing. An active bevel gear corresponding to the pigment can and the color mixing can is also fixedly installed on the outer wall of the rotating shaft. The motor is fixedly installed on the outer wall of the left side plate, and the output end of the motor is fixedly installed together with the first rotating rod at the left end.

[0010] In a preferred embodiment of this invention, the stirring shaft is provided with several shafts located in the pigment tank and the color mixing tank respectively. A second rotating rod is fixedly installed at the top of the stirring shaft. The second rotating rod is inserted and fixedly installed together with the second bearing. A driven bevel gear that meshes with the driving bevel gear is also fixedly installed at the top of the second rotating rod. A symmetrical set of scrapers is provided, and the scrapers are in close contact with the inner wall of the tank. The scrapers and the stirring shaft are also fixedly installed together by several vertically arrayed stirring rods.

[0011] As a preferred embodiment of this invention, both the pigment container and the color mixing container are fixedly installed with an electrically heated insulation sleeve on their outer walls.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the color matching mechanism, through the coordinated action of the electromagnetic flow valve, the first pump body, and the manifold, achieves precise control of the output of each pigment tank. The electromagnetic flow valve can precisely adjust the output of pigment according to the parameters set by the controller. Compared with the traditional manual filling method, it greatly reduces the filling error caused by subjective factors and external environmental influences. Different pigments enter the color mixing tank through the conveying pipe in a precise ratio, ensuring that the mixed paint color is highly consistent with the design expectation, significantly improving the overall effect of the advertising design and meeting the market's strict requirements for high-quality advertising design.

[0014] At the same time, the motor drives the rotating shaft to rotate, which in turn drives the active bevel gear to rotate. Through meshing with the driven bevel gear, the stirring shaft rotates synchronously in the pigment tank and the color mixing tank. The scraper is in close contact with the inner wall of the tank. Together with the stirring rod and the stirring shaft, the paint can be stirred in all directions without dead angles. This not only speeds up the mixing speed of various raw materials, but also ensures the uniformity of mixing, avoiding color deviation problems caused by insufficient mixing, and providing stable quality paint for advertising design.

[0015] In addressing the physical properties of coatings, the electric heating insulation jacket effectively solves the problem of coating viscosity or solidification. For coatings like acrylic paints, which are easily affected by temperature, the electric heating insulation jacket can maintain the coatings in the pigment can and color mixing can within a suitable temperature range according to the characteristics of the coatings. Under the action of stirring, the coatings can always maintain good fluidity. This not only facilitates the mixing and color matching of various raw materials, but also avoids the adverse effects of heating on the performance and quality of the coatings, ensuring the quality stability of the coatings and providing reliable coating support for the advertising design and painting process.

[0016] In addition, the design of the hydraulic cylinder and sealing cover enhances the sealing and safety of the device. During the color matching operation, the hydraulic cylinder drives the sealing cover to descend, sealing the pigment tank and the color mixing tank, preventing paint evaporation and the entry of external impurities, thus ensuring the purity and quality of the paint. At the same time, it also reduces the direct contact between the operator and the paint, improving the safety of the operation process. It also facilitates the subsequent addition of raw materials to the pigment tank and makes it easy to clean the pigment tank, the color mixing tank, and the mixing components.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figure 1 - Figure 5 As shown, a color matching device for advertising design with precise color application includes a frame 1 and a housing 2 fixedly connected to the top surface of the frame 1. A controller 3 is fixedly connected to the right side wall of the housing 2. A support plate 4 is also fixedly connected inside the housing 2. A color matching mechanism 5 is provided on the top surface of the support plate 4. The color matching mechanism 5 includes a first pump body 8, a second pump body 13, a hydraulic cylinder 16, a sealing cover plate 17, a rotating shaft 23, a driving bevel gear 25, a motor 26, a stirring shaft 27, a driven bevel gear 29, and a scraper 30. Several pigment tanks 6 and a color mixing tank 11 are fixedly connected to the top surface of the support plate 4. A manifold 9 is connected between the outlet of the pigment tanks 6 and the input end of the first pump body 8. A conveying pipe 10 is connected between the output end of the first pump body 8 and the inlet of the color mixing tank 11. A connecting pipe 14 is connected between the outlet of the color mixing tank 11 and the output end of the second pump body 13. A symmetrical hydraulic cylinder 16 is fixedly connected to the top surface of the support plate 4, and a sealing cover plate 17 is fixedly connected to the output end. The rotating shaft 23 is movably connected between the symmetrical side plates 18 on the top surface of the sealing cover plate 17 through the first rotating rods 24 at both ends. Several active bevel gears 25 are fixedly connected to the outer wall of the rotating shaft 23. One end of the first rotating rod 24 is fixedly connected to the output end of the motor 26. The stirring shaft 27 is movably connected to the bottom surface of the sealing cover plate 17 through the second rotating rod 28 at the top. The driven bevel gear 29 is fixedly connected to the top of the second rotating rod 28 and meshes with the active bevel gear 25. The scraper 30 is fixedly connected to the stirring shaft 27 through several stirring rods 31.

[0025] like Figure 3As shown, several pigment tanks 6 storing different colors of pigment are fixedly installed on the top surface of the support plate 4 in a horizontal array. An electromagnetic flow valve 7 is fixedly installed on the discharge port at the bottom of each pigment tank 6. A first pump body 8 is fixedly installed inside the bottom of the housing 2, and a manifold 9 is fixedly installed between the input end of the first pump body 8 and the electromagnetic flow valve 7. A conveying pipe 10 is fixedly installed on the output end of the first pump body 8. A color mixing tank 11 is fixedly installed on the right side of the top surface of the support plate 4, and a conveying pipe 10 is also fixedly installed between the side wall inlet of the color mixing tank 11 and the output end of the first pump body 8. A discharge valve 12 is fixedly installed at the bottom discharge port of the color mixing tank 11. A second pump body 13 is also fixedly installed inside the bottom of the housing 2, and a connecting pipe 14 is fixedly installed between the input end of the second pump body 13 and the discharge valve 12. A discharge pipe 15 extending out of the housing 2 is fixedly installed on the output end of the second pump body 13. Valve 7 can precisely control the outflow of primary color paint. Its principle is based on electromagnetic induction. It calculates the flow rate by measuring the induced electromotive force generated when the fluid flows in a magnetic field, thereby achieving precise control of paint usage. This effectively avoids errors caused by subjective factors and measurement tool precision issues in traditional manual filling, ensuring that the mixed paint color is highly consistent with the design expectation and improving the quality of advertising design. When the first pump body 8 is working, it uses negative pressure to transport the primary color paint, which has been precisely metered by the electromagnetic flow valve 7 in the pigment tank 6, through the manifold 9 and the conveying pipe 10 to the color mixing tank 11, realizing the automatic conveying of different primary color paints and improving the color mixing efficiency. After the mixed paint is mixed in the color mixing tank 11, the discharge valve 12 is opened, and the second pump body 13 works to discharge the mixed paint through the connecting pipe 14 and the discharge pipe 15, which is convenient for subsequent use. The whole process is highly automated and easy to operate.

[0026] like Figure 3 and Figure 4As shown, a set of symmetrical hydraulic cylinders 16 are fixedly installed on the top surface of the support plate 4, and a sealing cover plate 17 is fixedly installed on the output end of the symmetrical hydraulic cylinders 16. A set of symmetrical side plates 18 are fixedly installed on the top surface of the sealing cover plate 17, and a first mounting hole 19 is opened on the side wall of the side plate 18. A first bearing 20 is fixedly installed in the hole of the first mounting hole 19. A number of second mounting holes 21 corresponding to the pigment tank 6 and the color mixing tank 11 are also opened on the top surface of the sealing cover plate 17, and a second bearing 22 is fixedly installed in the hole of the second mounting hole 21. The hydraulic cylinders 16 generate pressure through the flow of hydraulic oil, which pushes the piston rod to move, thereby driving the sealing cover plate 17 to move up and down. When it is necessary to add oil to the pigment tank 6 and the color mixing tank 11, the sealing cover plate 17 can be adjusted accordingly. When adding raw materials or performing stirring operations in the color mixing tank 11, the hydraulic cylinder 16 pushes the sealing cover plate 17 down to make it fit tightly against the tank body, thus sealing it and preventing the paint from splashing out during stirring. This ensures the cleanliness and stability of the internal environment of the device and also facilitates the installation and operation of the subsequent stirring structure. When it is necessary to clean the tank or perform other operations, the hydraulic cylinder 16 drives the sealing cover plate 17 up to facilitate the operator's operation inside the tank. The first bearing 20 installed in the first mounting hole 19 on the side wall of the side plate 18 is used to cooperate with the first rotating rod 24 to achieve rotation operation, while the second bearing 22 installed in the second mounting hole 21 on the top surface of the sealing cover plate 17 is used to cooperate with the second rotating rod 28 to achieve rotation operation.

[0027] like Figure 5 As shown, the first rotating rod 24 is fixedly installed at the left and right ends of the rotating shaft 23, and the first rotating rod 24 is inserted and fixedly installed together with the first bearing 20. The outer wall of the rotating shaft 23 is also fixedly installed with the active bevel gear 25 corresponding to the pigment tank 6 and the color mixing tank 11. The motor 26 is fixedly installed on the outer wall of the side plate 18 on the left side, and the output end of the motor 26 is fixedly installed together with the first rotating rod 24 on the left side. When the motor 26 is working, it drives the rotating shaft 23 to rotate through the first rotating rod 24, so that the active bevel gear 25 rotates accordingly.

[0028] like Figure 5As shown, several stirring shafts 27 are provided and located in the pigment tank 6 and the color mixing tank 11 respectively. A second rotating rod 28 is fixedly installed at the top of the stirring shaft 27. The second rotating rod 28 is inserted and fixedly installed with the second bearing 22. A driven bevel gear 29 that meshes with the driving bevel gear 25 is also fixedly installed at the top of the second rotating rod 28. A set of scrapers 30 is provided symmetrically and is close to the inner wall of the tank. The scrapers 30 and the stirring shaft 27 are also fixedly installed together by several vertically arrayed stirring rods 31. When the driving bevel gear 25 rotates, it drives the driven bevel gear 29 to rotate through gear meshing, thereby causing the stirring shaft 27 to rotate. This transmission structure enables one motor 26 to drive multiple stirring shafts 27 to rotate at the same time. When the stirring shaft 27 rotates, it drives the stirring rods 31 and the scrapers 30 to rotate together. During rotation, the scraper 30 can scrape off the residual paint on the inner wall of the tank, preventing paint from accumulating on the tank wall, ensuring that all paint can participate in the mixing, improving the uniformity and efficiency of the mixing, making the mixed paint more uniform in color, and also facilitating the subsequent cleaning of the tank.

[0029] like Figure 3 As shown, both the pigment can 6 and the color mixing can 11 are fixedly equipped with electrically heated insulation sleeves 32. These sleeves convert electrical energy into heat energy through internal heating elements, heating and insulating the cans. Considering that acrylic paints may become viscous or even solidify after prolonged storage or in low-temperature environments, hindering color mixing, the electrically heated insulation sleeves 32 maintain the good fluidity of the paint within the cans, facilitating the mixing and blending of various raw materials, ensuring effective color mixing, and guaranteeing the quality of paints used in advertising design.

[0030] In advertising design, the color matching mechanism 5 achieves precise paint mixing through the coordinated operation of its various components. The specific working principle is as follows:

[0031] First, before starting the color mixing operation, the controller 3 starts the hydraulic cylinder 16, and its output pushes the sealing cover 17 down. During the descent, the sealing cover 17 gradually approaches the opening of the pigment tank 6 and the color mixing tank 11 until they are tightly fitted, sealing the pigment tank 6 and the color mixing tank 11. This prevents the paint from evaporating and external impurities from entering the tank during subsequent operations, ensuring the purity and quality of the paint, and also creating a good closed environment for subsequent mixing operations.

[0032] When it is necessary to mix paint of a specific color, the operator sets the usage parameters of various primary color paints through the controller 3. At this time, the electromagnetic flow valve 7 at the bottom of the pigment tank 6 starts to work. According to the parameters set by the controller 3, it accurately controls the outflow of primary color paint in each pigment tank 6 that needs to use the pigment. The electromagnetic flow valve 7 is based on the principle of electromagnetic induction. It calculates the flow rate by measuring the induced electromotive force generated when the fluid flows in the magnetic field, thereby achieving precise control of the amount of paint used. It effectively avoids the errors caused by subjective factors and the accuracy of measuring tools in traditional manual filling.

[0033] After the primary color paint in each pigment tank 6 flows out through the electromagnetic flow valve 7, it enters the manifold 9. Subsequently, the first pump 8 starts, and through its negative pressure, it draws the primary color paint from the manifold 9 and transports it through the delivery pipe 10 to the color mixing tank 11. Primary color paints of different colors enter the color mixing tank 11 in precise proportions, preparing for subsequent mixing and blending.

[0034] Simultaneously with the delivery of the primary color paint to the color mixing tank 11, the motor 26 starts. The output end of the motor 26 drives the left-end first rotating rod 24, which is fixedly connected to it, to rotate. Since the first rotating rod 24 is fixedly installed at both ends of the rotating shaft 23, and the first rotating rod 24 is inserted and fixedly installed with the first bearing 20 installed in the first mounting hole 19 on the side wall of the side plate 18, the rotating shaft 23 rotates synchronously with the rotation of the first rotating rod 24. When the rotating shaft 23 rotates, the active bevel gear 25, which is fixedly installed on its outer wall and corresponds to the pigment tank 6 and the color mixing tank 11, also rotates. The active bevel gear 25 meshes with the driven bevel gear 29, which is fixedly installed at the top of the second rotating rod 28 at the top of the stirring shaft 27. When the active bevel gear 25 rotates, it drives the driven bevel gear 29 to rotate through gear meshing, thereby causing the stirring shaft 27 to rotate. The second rotating rod 28 is fixedly installed at the top of the stirring shaft 27. The rotating rod 28 and the second rotating rod 28 are inserted and fixed together with the second bearing 22 installed in the second mounting hole 21 on the top surface of the sealing cover plate 17, which ensures that the stirring shaft 27 can rotate stably. When the stirring shaft 27 rotates, it drives the stirring rod 31 and scraper 30 fixedly connected to it to rotate together. The stirring rod 31 stirs the various primary color paints entering the color mixing tank 11, so that the paints of different colors are fully mixed. The scraper 30 is close to the inner wall of the tank. During the rotation, it can scrape off the paint residue on the inner wall of the tank, prevent the paint from accumulating on the tank wall, and ensure that all paints can participate in the mixing, which improves the uniformity and efficiency of stirring and makes the mixed paint color more uniform. At the same time, in the pigment tank 6, the stirring shaft 27 also drives the stirring rod 31 and scraper 30 to rotate, stirring the primary color paint in the pigment tank 6, preventing the paint from settling or separating, and ensuring the stability of the paint quality.

[0035] Furthermore, during the entire mixing process, considering that acrylic paints and other materials may become viscous or even solidify after prolonged storage or in low-temperature environments, which is not conducive to color matching, the electrically heated insulation sleeve 32 fixedly installed on the outer wall of the pigment tank 6 and the color mixing tank 11 plays a role. The electrically heated insulation sleeve 32 converts electrical energy into heat energy through internal electric heating elements to heat and insulate the tank, maintain the good fluidity of the paint inside the tank, facilitate the mixing and blending of various raw materials, ensure the color matching effect, and ensure the quality of the paint used for advertising design.

[0036] After the paint has been fully mixed and blended in the color mixing tank 11, the discharge valve 12 installed at the bottom outlet of the color mixing tank 11 is opened. At this time, the second pump body 13 is started. Through its negative pressure, the blended paint is drawn out through the connecting pipe 14 and discharged from the device through the discharge pipe 15 for use in advertising design and painting.

[0037] After the color matching operation is completed, the hydraulic cylinder 16 is started again, and its output end drives the sealing cover plate 17 to rise, so that the openings of the pigment tank 6 and the color mixing tank 11 are exposed, making it convenient for the operator to add raw materials into the pigment tank 6, and also making it convenient to clean the pigment tank 6, the color mixing tank 11 and the mixing components, so as to prepare for the next color matching operation.

[0038] In summary, through the coordinated work of the above components, the color matching mechanism 5 achieves precise mixing of paint for advertising design, ensuring that the mixed paint color is highly consistent with the design expectation, while guaranteeing the quality and stability of the paint, and meeting the demand of advertising design for high-quality paint.

[0039] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
