Abstract
Description
Technical Field
[0001] This utility model relates to the field of paint color matching technology, specifically a precise measuring device for paint color matching. Background Technology
[0002] Paint tinting is the process of mixing different colored base materials (or pigments) according to color principles and formulation rules to obtain a target color paint. Its core purposes include: matching needs: meeting the customized color requirements of architectural decoration, industrial products, and artistic creation (such as furniture paint color matching and automotive original paint restoration); controlling color difference: ensuring color consistency within the same or different batches of paint to avoid quality problems caused by color differences; and ensuring performance compatibility: taking into account the paint's hiding power, gloss, weather resistance, and other physical properties during the tinting process to prevent color adjustments from affecting the paint's inherent functionality.
[0003] Patent CN221108101U discloses a paint color mixing device, including a base, a rotating column rotatably connected to the upper end of the base, three supports fixedly connected to the rotating column, a positioning frame fixedly connected to the upper end of each support, a paint tank fixedly connected inside the positioning frame, a paint chamber inside the paint tank, a through hole inside the support, an electromagnetic valve fixedly connected to the lower side of the paint tank, a suction pump located in the through hole in the isolation chamber of the electromagnetic valve, the suction pump communicating with the electromagnetic valve, and an output pipe fixedly connected to the suction pump. By setting up paint tanks, electromagnetic valves, and suction pumps, different paint tanks contain raw materials of different colors. The controller controls the opening and closing of the electromagnetic valve and the start duration of the suction pump. The start duration of the suction pump controls the output amount of raw materials in the paint tank, thereby adjusting different colors by adjusting the output amount of different paint tanks. The controller can also control the motor to drive different output pipes to align with different color mixing tanks for adjusting multiple colors.
[0004] However, when the above-mentioned patent is used, the paint tank is fixedly connected to the positioning frame, which makes it impossible to remove the paint tank for cleaning. The old paint is difficult to clean completely, resulting in the mixing of new and old paint and affecting the color matching effect. At the same time, the output is determined by the suction pump and solenoid valve based on the duration. However, due to the influence of paint viscosity and pressure, the output of paint with different viscosities varies in the same time, resulting in inaccurate measurement and deviation in color matching. Utility Model Content
[0005] The purpose of this invention is to provide a precise metering device for paint color matching, in order to solve the problems mentioned in the background art, such as paint tanks being unable to be disassembled for cleaning, old paint being difficult to clean completely, resulting in mixing of new and old paint and affecting the color matching effect. At the same time, the output volume is determined by the duration of the suction pump and solenoid valve, but is affected by the viscosity and pressure of the paint, resulting in different output volumes of paints of different viscosities within the same time, leading to inaccurate metering and deviations in color matching.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a precise color-matching and metering device for paint, comprising a base, a connecting shaft, a paint tank, and a vertical rod. The connecting shaft is located within the inner cavity of the base, the paint tank is located on both sides of the connecting shaft, and the vertical rod is located on both sides of the connecting shaft. A sliding groove is formed around the top outer side of the base. A first connecting rod is fixedly connected to the upper side of the outer wall of the connecting shaft, and an electric push rod is fixedly connected to the lower outer side of the first connecting rod. A second connecting rod is fixedly connected to the middle of the outer wall of the connecting shaft. A second groove is formed at the top of the second connecting rod, and a through hole is formed at the bottom of the inner cavity of the second groove. A piston is slidably connected to the upper side of the inner wall of the paint tank. A first connecting tube is integrally formed at the bottom end of the paint tank, and a second connecting tube is inserted into the inner cavity of the through hole.
[0007] As a further description of the above technical solution:
[0008] The base has a color mixing groove around its top outer edge, and a first groove at the top center of the base. A stepper motor is fixedly connected to the bottom of the inner cavity of the first groove.
[0009] As a further description of the above technical solution:
[0010] A bearing is fixedly connected between the upper inner walls of the first groove, and the connecting shaft is fixedly inserted into the inner cavity of the bearing. The bottom end of the connecting shaft is fixedly connected to the output end of the stepper motor.
[0011] As a further description of the above technical solution:
[0012] The paint can is movably inserted into the inner cavity of the second groove, the output end of the electric push rod is screwed to the top center of the piston, and the first connecting pipe is inserted into the inner cavity of the second connecting pipe.
[0013] As a further description of the above technical solution:
[0014] A check valve is fixedly connected to the bottom end of the second connecting pipe, and a discharge pipe is fixedly connected to the output end of the check valve.
[0015] As a further description of the above technical solution:
[0016] The upright is fixedly connected to the bottom outer side of the second connecting rod, and a retaining seat is fixedly connected to the bottom of the upright. A ball bearing is movably engaged in the inner cavity of the retaining seat, and the ball bearing is rotatably connected to the inner cavity of the slide groove.
[0017] As a further description of the above technical solution:
[0018] A controller is embedded in the front side of the outer wall of the base, and the controller is electrically connected to a stepper motor and an electric push rod.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] 1. This precise color mixing and metering device for paint uses a paint tank with a piston on the upper inner wall. The piston is connected to an electric push rod. The discharge volume of the paint is determined by the extension stroke of the electric push rod, which in turn determines the volume of the paint. This design is unaffected by paint viscosity and pressure, ensuring accurate discharge. By inserting the paint tank into a second groove, the first and second connecting pipes are stably connected. When cleaning is required, the screw-on electric push rod can be rotated to separate the piston, allowing for quick cleaning by removing the paint tank and piston. This effectively prevents the mixing of new and old paints and ensures the color mixing effect.
[0021] 2. This paint color matching precision metering device effectively prevents leakage and pollution by setting a check valve between the second connecting pipe and the discharge pipe. The uprights, brackets and ball bearings at both ends of the second connecting rod slide in the groove, making the rotation of the second connecting rod by the connecting shaft smoother and more stable.

[0036] In summary: By setting up a paint tank 300, with a piston 310 installed on the upper side of the inner wall of the paint tank 300, and the piston 310 connected to an electric push rod 220, the discharge volume of the discharge pipe 350 is determined by the extension stroke of the electric push rod 220, and the volume of the paint is determined by the extension stroke of the electric push rod 220. This ensures accurate discharge volume regardless of paint viscosity and pressure. By inserting the paint tank 300 into the second groove 240, the first connecting pipe 320 and the second connecting pipe 330 are stably connected.
