Description
Technical Field
[0001] This utility model relates to the field of latex paint color matching technology, specifically to a color matching device for producing latex paint. Background Technology
[0002] Latex paint is a water-based coating formulated with synthetic resin emulsions as the base (such as polyvinyl acetate, acrylic acid, etc.), and the addition of pigments (to provide color), fillers (to enhance hiding power and texture), and additives (such as film-forming agents, dispersants, etc.). Because it uses water as the dispersion medium, it is an environmentally friendly organic coating, also known as a synthetic resin emulsion coating. During the production process, latex paint needs to be tinted according to production requirements.
[0003] Existing patent CN221772040U discloses a color mixing device for producing latex paint, including a workbench with a fixing hole on the upper side. A color mixing tank is fixed inside the fixing hole, and a discharge hole is provided on the lower side of the color mixing tank. An A discharge pipe is fixed inside the discharge hole, and an A-type electric control valve is fixed on one side of the A-type discharge pipe. The A-type electric control valve needs to be connected to an external power supply and switch via wires. A support frame is fixed on the outer periphery of the color mixing tank, and a servo motor is fixed on the upper side of the support frame. By setting up the workbench, support legs, color mixing tank, A-type discharge pipe, support frame, servo motor, drive rod, scraper, connecting block, support plate, stirring motor, stirring shaft, stirring rod, connecting shaft, and reinforcing block, it has a scraping function, which can scrape off the latex paint adhering to the inner wall of the color mixing tank. Combined with rinsing with clean water, it is easier to clean the latex paint adhering to the inner wall of the color mixing tank, and it will not affect the next color mixing.
[0004] Based on the search of the aforementioned patents and in conjunction with existing color mixing devices, it was found that although the aforementioned color mixing devices can switch between different pigment storage tanks during use, the pigments in the storage tanks are discharged solely by gravity, resulting in relatively slow pigment discharge and affecting color mixing efficiency. In addition, if the outside temperature is low, the latex paint is difficult to stir, thus reducing its practicality. Utility Model Content
[0005] The purpose of this invention is to provide a color mixing device for producing latex paint, in order to solve the problems mentioned in the background art. Although the existing color mixing devices can switch between different pigment storage tanks, the pigments in the storage tanks are discharged by gravity alone, which results in relatively slow pigment discharge and affects color mixing efficiency. At the same time, if the outside temperature is low, it is difficult to stir the latex paint, thus reducing its practicality.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a color mixing device for producing latex paint, comprising a base, a color mixing cylinder fixedly connected to the top of the base, a material pushing component on the top of the base, and a heating component inside the color mixing cylinder;
[0007] The pushing component includes a first rotating shaft connected to one side of the top of the base, a first motor fixedly connected to the bottom of the first rotating shaft, a fixed seat fixedly connected to the top of the first rotating shaft, a second motor fixedly connected to one side of the bottom of the fixed seat, a screw fixedly connected to the top of the second motor, a drive plate connected to the outside of the screw, a moving rod fixedly connected to the four sides of the drive plate, a piston fixedly connected to the bottom of the moving rod, and a drive component for switching the piston. The screw is screwed to the drive plate and rotatably connected to the fixed seat.
[0008] Preferably, the heating component includes a heating chamber opened inside the color mixing cylinder, a heating wire fixedly connected to the inner wall of the heating chamber, a plurality of trapezoidal grooves evenly arranged on one side of the heating chamber, a third motor fixedly connected to the bottom of the base, a stirring rod fixedly connected to the top of the third motor, and a stirring blade fixedly connected to the stirring rod. The stirring rod is rotatably connected to the base and the color mixing cylinder respectively.
[0009] Preferably, a second rotating shaft is rotatably connected to the top of the base away from the first rotating shaft, and horizontal plates are fixedly connected to the second rotating shaft around its perimeter. A pigment cylinder is fixedly connected to one side of the horizontal plate, and a solenoid valve is installed at the bottom of the pigment cylinder.
[0010] Preferably, a main gear is fixedly connected to the outer side of the first rotating shaft, and a driven gear is fixedly connected to the outer side of the second rotating shaft. A toothed belt is sleeved on the outer side of the main gear and the driven gear, and both the main gear and the driven gear mesh with the toothed belt.
[0011] Preferably, a rotating disk is fixedly connected to the outer side of both the first and second rotating shafts, a rotating block is fixedly connected to each of the two bottom sides of the rotating disk, and a rotating groove is opened on each of the two top sides of the base, and the rotating block is slidably connected to the rotating groove.
[0012] Preferably, an anti-rotation rod is fixedly connected to the top of the fixed base on the side away from the screw, and the anti-rotation rod passes through the drive plate and is slidably connected to the drive plate.
[0013] Preferably, scraper plates are fixedly connected to both sides of the stirring rod, and the scraper plates are L-shaped.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. By setting up a base, a color mixing cylinder, and a material pushing component, the second motor can drive the screw to rotate, which in turn drives the drive plate to move downward, which in turn pushes the piston downward. The piston can move into the pigment cylinder, which can push the pigment downward, thereby accelerating its discharge efficiency and improving the color mixing efficiency. The first motor can drive the first rotating shaft to rotate, which can switch to different pistons according to different pigment cylinders to prevent color mixing between different pigments, ensuring the color mixing effect, and thus greatly improving the practicality and efficiency of the device.
[0016] 2. By incorporating a heating element, the air inside the heating chamber can be heated by energizing the heating wire, which in turn transfers the heat to the inner wall of the heating chamber. The trapezoidal groove increases the contact area, allowing the heat to be quickly transferred to the latex paint. This provides a certain degree of heating to the latex paint, which can assist in stirring and color matching, preventing the latex paint from becoming difficult to stir due to low temperature.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides a technical solution: a color mixing device for producing latex paint, including a base 1, a color mixing cylinder 11 fixedly connected to the top of the base 1, a pushing component on the top of the base 1, and a heating component inside the color mixing cylinder 11. The pushing component includes a first rotating shaft 21 connected to one side of the top of the base 1, a first motor 22 fixedly connected to the bottom of the first rotating shaft 21, a fixed seat 23 fixedly connected to the top of the first rotating shaft 21, a second motor 24 fixedly connected to one side of the bottom of the fixed seat 23, a screw 25 fixedly connected to the top of the second motor 24, a drive plate 26 connected to the outside of the screw 25, moving rods 27 fixedly connected to the four sides of the drive plate 26, a piston 28 fixedly connected to the bottom of the moving rods 27, and a drive for switching the piston 28. The components include a screw 25 screwed to a drive plate 26 and a fixed base 23. A second motor 24 drives the screw 25 to rotate, which in turn drives the drive plate 26 and piston 28 to move vertically. The piston 28 enters the pigment cylinder 43, which pushes the pigment inside the pigment cylinder 43 to be discharged quickly, thereby improving adjustment efficiency. A first motor 22 drives the first rotating shaft 21 to rotate, which in turn drives multiple pistons 28 to rotate. Different pistons 28 can be switched according to different pigment cylinders 43 to avoid pigment cross-contamination. A second rotating shaft 41 is rotatably connected to the top of the base 1 away from the first rotating shaft 21. Horizontal plates 42 are fixedly connected to the second rotating shaft 41 around its perimeter. A pigment cylinder 43 is fixedly connected to one side of the horizontal plate 42. A solenoid valve 44 is installed at the bottom of the 3rd shaft, and a scale is installed on the outside of the pigment cylinder 43. The pigment cylinder 43 is made of transparent material. The rotation of the second shaft 41 can drive the rotation of the pigment cylinder 43, allowing for the switching of different pigment cylinders 43. The solenoid valve 44 can control the opening and closing of the pigment cylinder 43 to facilitate pigment discharge. A main gear 51 is fixedly connected to the outside of the first shaft 21, and a driven gear 52 is fixedly connected to the outside of the second shaft 41. A toothed belt 53 is fitted on the outside of the main gear 51 and the driven gear 52. Both the main gear 51 and the driven gear 52 mesh with the toothed belt 53. The first shaft 21 can drive the main gear 51 to rotate, which in turn drives the toothed belt 53 to rotate, which in turn drives the driven gear 52 to rotate, which in turn drives the second shaft 41 to rotate. No additional power is required to drive the second shaft 41. The rotation of the two rotating shafts 41 facilitates the switching of different pigment cartridges 43. Rotating disks 61 are fixedly connected to the outer sides of both the first and second rotating shafts 21. Rotating blocks 62 are fixedly connected to the bottom sides of each rotating disk 61. Rotating grooves 63 are respectively opened on the top sides of the base 1. The rotating blocks 62 are slidably connected to the rotating grooves 63. The first and second rotating shafts 21 and 41 can drive the rotating disks 61 to rotate, which in turn drives the rotating blocks 62 to rotate. The rotating blocks 62 improve the rotational stability of the first and second rotating shafts 21 and 41. An anti-rotation rod 71 is fixedly connected to the top of the fixed base 23 on the side away from the screw 25. The anti-rotation rod 71 passes through the drive plate 26 and is slidably connected to the drive plate 26. When the drive plate 26 moves, it can slide outside the anti-rotation rod 71.The anti-rotation rod 71 prevents the drive plate 26 from rotating.
[0025] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The heating components include a heating chamber 31 located inside the color mixing cylinder 11, a heating wire 32 fixedly connected to the inner wall of the heating chamber 31, multiple trapezoidal grooves 33 evenly arranged on one side of the heating chamber 31, a third motor 34 fixedly connected to the bottom of the base 1, a stirring rod 35 fixedly connected to the top of the third motor 34, and a stirring blade 36 fixedly connected to the stirring rod 35. The stirring rod 35 is rotatably connected to both the base 1 and the color mixing cylinder 11. When the heating wire 32 is energized, it can heat the air inside the heating chamber 31, thereby transferring heat to the inner wall of the heating chamber 31. The trapezoidal groove 33 increases the contact area, allowing heat to be quickly transferred to the latex paint, thus heating the latex paint. The third motor 34 starts, which drives the stirring rod 35 to rotate, which in turn drives the stirring blade 36 to rotate, allowing the pigment and latex paint to be mixed and tinted. Scraper plates 81 are fixedly connected to both sides of the stirring rod 35. The scraper plates 81 are L-shaped. The rotation of the stirring rod 35 drives the scraper plates 81 to rotate, which can scrape off the latex paint residue on the inner wall of the tinting cylinder 11, making it easier to rinse and clean the tinting cylinder 11.
[0026] Working principle: During operation, the first motor 22 is started, which drives the first rotating shaft 21 to rotate. The rotation of the first rotating shaft 21 drives the main gear 51 and the fixed seat 23 to rotate. The rotation of the main gear 51 drives the driven gear 52 to rotate via the toothed belt 53. The rotation of the driven gear 52 drives the second rotating shaft 41 to rotate, which in turn drives the pigment cylinder 43 to rotate. This allows for switching of the pigment cylinder 43. The rotation of the fixed seat 23 drives the piston 28 to rotate. When the pigment cylinder 43 rotates to the top of the mixing cylinder 11, the piston 28 also rotates to the top of the mixing cylinder 11, the solenoid valve 44 opens, the first motor 22 closes, and the second motor 24 starts. The start of the second motor 24 drives the screw 25 to rotate, which in turn drives the drive plate 26 to move downward. The downward movement of the drive plate 26 drives the moving rod 27 to move downward, which in turn drives the piston 28 to move downward. The piston 28 moves into the pigment cylinder 43 and pushes the pigment to move, allowing the pigment to be quickly discharged into the mixing cylinder 11. The solenoid valve 44 closes, the second motor 24 reverses, causing the piston 28 to move upward and reset. The third motor 34 starts, which drives the stirring rod 35 to rotate, and in turn drives the stirring blade 36 to rotate. The heating wire 32 is energized to heat the air in the heating chamber 31, which in turn transfers heat to the inner wall of the heating chamber 31. The trapezoidal groove 33 increases the contact area, which allows the heat to be quickly transferred to the latex paint, thus heating the latex paint and facilitating the mixing and color matching of the latex paint and pigment. When it is necessary to switch to another pigment, the above operation is repeated to switch to another pigment cylinder 43. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
