Description

Technical Field

[0001] The invention relates to a color matching device, in particular to a color matching device for fully mixed advertising design, belonging to the technical field of coating color matching. Background Art

[0002] In the field of advertising design, although physical color mixing devices are not used as frequently as traditional painting or paint mixing, they may be used in some specific situations, such as when large-scale advertising material production (such as large-scale outdoor inkjet printing, exhibition display props, etc.) requires mixing a large amount of pigments or inks, or when some creative hand-made parts related to advertising design are being made;

[0003] In the prior art, the utility model with application number 201920841642.2 discloses a pigment mixing device for billboard spray painting. In order to solve the problems that the existing pigment mixing device for billboard spray painting has poor stirring effect and insufficient pigment mixing; and the pigment is easily accumulated on its inner wall and forms plates, resulting in a reduction in the volume of the mixed material and inconvenience in use, through the design of a driving device, a screw rod, a nut, a scraper ring, a circular ring, a stirring blade and an accordion protective cover, a motor drives the screw rod to rotate, and the screw rod drives the stirring blade to rotate through a second slide groove, a second slider and a circular ring in turn to mix and stir the pigment in the stirring barrel. At the same time, the screw rod drives the scraper ring to slide up and down along the inner wall of the stirring barrel through a nut and a connecting rod in turn, and the scraper ring scrapes off the pigment adhered to the inner wall of the stirring barrel, thereby avoiding the pigment from caking on the inner wall of the stirring barrel, resulting in a reduction in the volume of the mixed material and inconvenience in use; at the same time, the nut drives the circular ring to move up and down through the accordion protective cover, so that the stirring blade moves up and down to mix and stir the pigments at different heights in the stirring barrel, thereby improving the stirring efficiency and fully mixing the pigments.

[0004] Similar to the above application, there are still some shortcomings:

[0005] Although the stirring blade can be adjusted up and down in height during the use of the equipment, the rotation direction of the driving motor needs to be changed frequently, which makes it inconvenient for the stirring blade to continuously move up and down and rotate. At the same time, the flow stirring effect of the bottom pigment is poor during the stirring process, which affects the mixing rate. In addition, the ink pigment has a certain viscosity during use and cannot be fed automatically and quickly, so its practicality is low.

[0006] For this reason, a color matching device for advertising design with sufficient mixing is designed to optimize the above-mentioned problems. Summary of the invention

[0007] The main purpose of the present invention is to provide a color matching device for advertising design with sufficient mixing. The mixing chamber is installed on the side of the output shaft of the driving motor through a fixing rod, and a U-shaped stirring blade is arranged inside the mixing box. In combination with a rotating mechanism composed of an annular groove, an inner gear ring, a control chamber, a cylindrical rod, a gear, a corrugated groove, a vertical groove, a cross rod, a bearing, an L-shaped rod, a rectangular rod, and an axle rod, the mixing box can be controlled to make a circular motion on the top of the base during the mixing process, and the U-shaped stirring blade is controlled by the rotating mechanism to rotate and lift continuously and reciprocally inside the mixing box to increase the fluidity of the pigment. In combination with a circulation reflux mechanism composed of a cavity, a first piston, a connecting rod, an annular tube, a spray hole, and a circulation tube, the mixing box can be moved in a circular motion. The bottom pigment is transported upward and sprayed out, which increases the flow rate of the pigment again, improves the stirring effect during use, and makes the pigment mixing more complete. By distributing multiple groups of pigment cans in a circular array on the top of the mixing box, automatic batching can be performed during the rotation of the mixing box. In addition, due to the viscous nature of the pigment, during the rotation of the drive motor, the inflation assembly consisting of the upper sleeve, V-shaped groove, lower sleeve, conical protrusion, fixed plate, first spring, air cavity, second piston, and slide rod and the pressure tank, air intake pipe, third piston, second spring, and exhaust pipe high-pressure air supply assembly are used to ensure that the interior of the pigment can is in a high-pressure state, the pigment can be quickly discharged and added, and the batching rate is improved.

[0031] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0032] like Figure 1-Figure 8 As shown, the present embodiment provides a color matching device for advertising design with sufficient mixing, including a base 1, a mounting frame 2 is fixed at one end of the top of the base 1, a fixed plate 3 is horizontally installed on the top of the mounting frame 2, paint cans 4 are evenly installed on the fixed plate 3 along the circumferential direction, a high-pressure air supply component 5 which is connected to the inside of the paint can 4 is provided at the middle position of the top of the fixed plate 3, an inflation component 6 which supplies air to the inside of the high-pressure air supply component 5 is provided inside the base 1, a driving motor 7 is installed at the middle position of the bottom of the fixed plate 3, a fixing rod 8 is vertically installed at the output end of the driving motor 7, a mixing box 9 located below the paint can 4 is vertically installed at the end of the fixing rod 8, a U-shaped stirring blade 10 is installed inside the mixing box 9, a rotating mechanism 11 for controlling the rotation of the U-shaped stirring blade 10 is provided at the bottom of the mixing box 9, and a circulating reflux mechanism 12 for the upward and downward flow of the paint is provided on the mixing box 9.

[0033] The overall working principle is as follows: when in use, first start the drive motor 7 and rotate it for one circle, and use the inflation component 6 to inflate the interior of the high-pressure air supply component 5, thereby ensuring that the interior of the paint tank 4 is in a high-pressure state, so that the paint can flow out quickly during the process of adding the paint, and then control the drive motor 7 again to slowly drive the mixing box 9 to move. When the mixing box 9 reaches the bottom of the paint tank 4 of the specified color, the paint is added. In addition, during the rotation of the drive motor 7, the interior of the high-pressure air supply component 5 can be inflated again to ensure that the interior of the paint tank 4 is always in a high-pressure state. After the paint falls into the mixing box 9, as the drive motor 7 rotates, it can not only drive the mixing box 9 to perform a circular motion, but also the rotating mechanism 11 will drive the U-shaped stirring blade 10 to rotate to stir the inside of the paint. In addition, the circulating reflux mechanism 12 transports and discharges the paint at the bottom of the mixing box 9 to the top, thereby increasing the mixing effect and rate.

[0034] In this embodiment, six groups of paint cans 4 are provided, and the interiors of the paint cans 4 are respectively provided with the three primary colors of red, yellow and blue and the achromatic colors of black, white and gray. The discharge outlets at the bottoms of the paint cans 4 are provided with flow meters and solenoid valves.

[0035] Partial working principle: During the process of adding pigment, the flow meter is used to accurately control the amount of pigment added. After the amount of pigment added is reached, the controller will control the closure of the solenoid valve to block the continued outflow of pigment.

[0036] In this embodiment, the rotating mechanism 11 includes a control chamber 15, a columnar rod 16, a corrugated groove 18, a vertical groove 19, a cross bar 20, an L-shaped rod 22, a rectangular rod 23, an axle rod 24 and a driving part. The control chamber 15 is opened at the bottom end of the mixing box 9. The columnar rod 16 is vertically rotatably installed at the middle position of the bottom of the control chamber 15. The bottom end of the columnar rod 16 extends to the bottom of the mixing box 9, and the bottom end of the columnar rod 16 is provided with a driving part for controlling the rotation of the columnar rod 16. The outer side of the columnar rod 16 is provided with a corrugated groove 18, and the top of the side of the control chamber 15 is symmetrically provided with a vertical groove 19. Groove 19, a cross bar 20 is vertically slidably provided between the two groups of vertical grooves 19, an L-shaped rod 22 is symmetrically installed at the bottom of the cross bar 20, the bottom end of the L-shaped rod 22 is inserted into the inside of the corrugated groove 18 and slides inside the corrugated groove 18, a rectangular rod 23 is vertically slidably provided at the top of the columnar rod 16, a shaft rod 24 extending to the inside of the mixing box 9 is fixed at the top of the rectangular rod 23, a U-shaped stirring blade 10 is fixed at the top of the shaft rod 24, a bearing 21 is installed at the middle position of the cross bar 20, the shaft rod 24 passes through the inside of the bearing 21 and is fixedly connected to the inner ring of the bearing 21.

[0037] Local working principle: when the pigment inside the mixing box 9 is stirred, the driving part is used to control the rotation of the cylindrical rod 16. The rotation of the cylindrical rod 16 will control the rotation of the rectangular rod 23 and the shaft rod 24, and then control the U-shaped stirring blade 10 to rotate and stir. In addition, during the rotation of the cylindrical rod 16, the L-shaped rod 22 will slide inside the corrugated groove 18. Since the two ends of the cross bar 20 are limited, the L-shaped rod 22 can only drive the cross bar 20 to move vertically, and the cross bar 20 is rotatably connected to the shaft rod 24, which can drive the shaft rod 24 to move vertically. Therefore, the U-shaped stirring blade 10 moves up and down at the same time during the rotation process, increasing the fluidity of the pigment, and the outer side of the U-shaped stirring blade 10 contacts the inner wall of the mixing box 9. When the U-shaped stirring blade 10 moves to the bottom of the mixing box 9, it can fit the bottom end of the mixing box 9, so that the mixing box 9 can be scraped for pigment, which has a better stirring effect on the pigment.

[0038] In the present embodiment, the bottom end of the L-shaped rod 22 is cylindrical, and a ball bearing is installed at the bottom end of the L-shaped rod 22 , and the ball bearing contacts the inner side of the corrugated groove 18 .

[0039] Partial working principle: When the end of the L-shaped rod 22 slides inside the corrugated groove 18 , the setting of the ball bearing can reduce the friction resistance and reduce the wear on the L-shaped rod 22 and the corrugated groove 18 .

[0040] In this embodiment, the driving part includes an annular groove 13, an inner gear ring 14 and a gear 17. The annular groove 13 is opened at the top of the base 1, and the inner gear ring 14 is installed on the outer side of the annular groove 13. The gear 17 is fixedly installed at the bottom end of the cylindrical rod 16, and the gear 17 is meshed with the inner gear ring 14.

[0041] Partial working principle: During the rotation of the driving motor 7 , the gear 17 is driven to rotate around the annular tooth groove 13 , thereby controlling the rotation of the gear 17 and driving the cylindrical rod 16 to rotate.

[0042] In this embodiment, the circulation reflux mechanism 12 includes a cavity 25, a first piston 26, a connecting rod 27, an annular tube 28 and a spray hole 29. The cavity 25 is opened at the inner top of the control chamber 15. The first piston 26 is slidably installed inside the cavity 25. A connecting rod 27 is fixed between the bottom of the first piston 26 and the cross bar 20. A through opening is provided between the top of the cavity 25 and the interior of the mixing box 9, and a one-way liquid inlet valve is provided at the through opening. An annular tube 28 is fixed to the top of the outer side of the mixing box 9 along the circumferential direction, and spray holes 29 that are connected to the interior of the mixing box 9 are evenly opened on the inner side of the annular tube 28. A circulation tube 30 is provided between the top of the cavity 25 and the annular tube 28, and a one-way discharge valve is provided on the circulation tube 30.

[0043] Local working principle: During the up and down sliding of the cross bar 20, the connecting rod 27 can drive the first piston 26 to slide downward inside the cavity 25, and the pigment at the bottom of the mixing box 9 can be drawn into the cavity 25. During the rising process, the first piston 26 can squeeze the pigment inside the cavity 25 into the annular tube 28 through the circulation pipe 30, and then discharge it from the inner bottom of the spray hole 29 to the top of the pigment, so as to transport the pigment up and down.

[0044] In this embodiment, the high-pressure air supply component 5 includes a pressure tank 40, an air inlet pipe 41, a third piston 42, a second spring 43 and an exhaust pipe 44. The pressure tank 40 is fixed between the top of the fixed plate 3 and the top of the mounting frame 2. The third piston 42 is slidably provided inside the pressure tank 40, and the second spring 43 is installed at the bottom of the third piston 42. An exhaust pipe 44 is installed between the top of the outer side of the pressure tank 40 and the paint tank 4. The top of the pressure tank 40 is provided with an air inlet pipe 41, and the inside of the base 1 is provided with an inflation component 6 which is connected to the air inlet pipe 41.

[0045] Local working principle: During use, the inflation component 6 is used to squeeze the gas to the inner top of the pressure tank 40. The increased pressure inside the pressure tank 40 will control the downward movement of the third piston 42 and squeeze the second spring 43. When the paint is discharged, the gas will enter the interior of the paint tank 4 through the exhaust pipe 44, and quickly squeeze out the paint.

[0046] In this embodiment, the inflation component 6 includes an air cavity 37, a second piston 38, a sliding rod 39 and a telescopic part. The air cavity 37 is opened inside the base 1, and the bottom end of the air inlet pipe 41 is connected to the inside of the air cavity 37. The second piston 38 is slidably arranged inside the air cavity 37. The top of the second piston 38 is fixed with a sliding rod 39 extending to the top of the base 1. The sliding rod 39 is slidably connected to the base 1. The sliding rod 39 can only slide vertically, and the top of the sliding rod 39 is provided with a telescopic part for controlling the sliding rod 39 to slide up and down. A one-way air inlet valve is provided at the end of the air cavity 37 away from the air inlet pipe 41, and a one-way exhaust valve is provided on the air inlet pipe 41.

[0047] Local working principle: When inflating, the telescopic part continuously controls the second piston 38 to slide inside the air chamber 37, takes in air from the one-way air inlet valve, and then injects it into the pressure tank 40 through the one-way exhaust valve and the air inlet pipe 41, thereby increasing the internal pressure of the pressure tank 40.

[0048] In this embodiment, the telescopic part includes an upper sleeve 31, a V-shaped groove 32, a lower sleeve 33, a conical protrusion 34, a fixing plate 35 and a first spring 36. The upper sleeve 31 is fixed to the output end of the driving motor 7. The bottom end of the upper sleeve 31 is symmetrically provided with a V-shaped groove 32. The bottom of the upper sleeve 31 is provided with a lower sleeve 33. The top of the lower sleeve 33 is symmetrically provided with conical protrusions 34 that cooperate with the V-shaped groove 32. The conical protrusions 34 are inserted into the interior of the V-shaped groove 32. The bottom end of the lower sleeve 33 is horizontally fixed with a fixing plate 35. A first spring 36 is provided between the bottom of the fixing plate 35 and the base 1. The sliding rod 39 passes through the interior of the first spring 36 and is fixedly connected to the fixing plate 35.

[0049] Local working principle: when the driving motor drives the upper sleeve 31 to rotate, the V-shaped groove 32 and the conical protrusion 34 are misaligned, squeezing the lower sleeve 33 downward. The downward movement of the lower sleeve 33 will not only control the compression of the first spring 36 but also drive the downward movement of the second piston 38 to complete the inflation operation of the pressure tank 40. After the upper sleeve 31 rotates one hundred and eighty degrees, the conical protrusion 34 is inserted into the interior of the V-shaped groove 32 again to reset. At this time, the second piston 38 completes an inflation process and inhales and resets, repeatedly controlling the rotation of the upper sleeve 31, and the inflation of the pressure tank 40 can be continued.

[0050] In this embodiment, an air inlet 45 is provided at the top of the base 1 , a filter screen 46 is provided at the inner top of the air inlet 45 , and the bottom end of the air inlet 45 is connected to a one-way air inlet valve at the side of the air cavity 37 through a conduit.

[0051] Partial working principle: When external gas enters the air cavity 37, the gas can be filtered to prevent impurities in the air from contaminating the pigment.
