Description

Technical Field

[0001] The present invention specifically relates to an automatic color matching device for water-based paint, and belongs to the technical field of paint color matching. Background Art

[0002] Water-based paint has become the mainstream development direction of the paint industry due to its low VOC emissions, environmental protection and safety. It is widely used in architectural decoration, automobile manufacturing, furniture painting and other fields. Its color matching process is to mix the base material, auxiliary materials and other components in proportion to achieve the color and performance that meets the requirements.

[0003] However, most companies currently still rely on manual color matching for water-based paints. This traditional method severely restricts production efficiency and product quality stability. Manual color matching is extremely inefficient. Colorists need to manually weigh base materials and auxiliary materials based on experience or color card comparison, and then add them one by one to the container to mix. This process is not only cumbersome, but also time-consuming each time. Faced with the demand for multiple varieties of orders, work efficiency is low and it is difficult to meet the requirements of fast delivery.

[0017] Beneficial effects:

[0018] 1. The innovatively designed rotary mechanism and color matching mechanism of the present invention work in coordination: the rotating table is equipped with multiple groups of material storage barrels that rotate at a constant speed. When the material storage barrels pass under the base material tube in turn, the metering pump injects the water-based paint base material into the material storage barrel according to the preset formula parameters; when the material storage barrel rotates to the switching rod area, the multiple groups of switching rods realize angle control based on the preset program, and orderly drive the corresponding auxiliary material barrels to rotate at the set angle to the top of the material storage barrel, and then the metering pump 2 is linked to the discharge valve to deliver the auxiliary material to the material storage barrel in a quantitative manner according to the ratio.

At the same time, the mixing rod and scraper rod in the storage barrel rotate to facilitate the removal of the material adhering to the inner wall. The wastewater generated by the flushing is directly discharged into the wastewater tank through the discharge valve. After completing the cleaning of a single group of storage barrels, the rotating table rotates and switches to move the next group of storage barrels to the cleaning station, thereby improving cleaning efficiency.

When the stepping motor receives a pulse signal from the control system, its output shaft rotates precisely according to a preset angle (such as 60°, 120°, etc.), thereby driving the rotating plate 21 to rotate synchronously. Since the six groups of switching rods 22 are installed on the outer edge of the rotating plate 21 in a circular and equidistant manner, the rotation of the rotating plate 21 will drive all the switching rods 22 to perform circular motion around the central axis of the fixed column 24.

[0043] When used specifically, the working principle of the present invention is as follows:

[0044] After the recipe parameters are preset through the control console 16, the rotating motor 18 drives the rotating table 12 to start rotating, and multiple groups of storage barrels 15 pass under the base material pipe 212 in turn, and the metering pump 26 injects the water-based paint base material in the base material tank 210 into the storage barrel 15 in a quantitative manner according to the recipe amount; the rotating table 12 continues to rotate, and when the storage barrel 15 reaches the switching rod 22 area, the stepping motor drives the rotating plate 21 to rotate, driving the corresponding multiple groups of auxiliary material barrels 23 to rotate in turn to the top of the storage barrel 15 according to the preset angle, and the metering pump 211 injects the auxiliary material according to the ratio through the discharge port. Valve 28 injects the material into the storage barrel 15; after injection, the mixing motor 112 drives the mixing rod 111 and the scraper rod 110 to rotate, shearing, dispersing and mixing the base material and the auxiliary material. After the mixing is completed, when the rotating table 12 rotates the storage barrel 15 to the top of the paint container 14, the discharge valve 113 opens, and the finished paint is discharged into the paint container 14. After discharge, the paint container 14 is removed from the container slot plate 13 and replaced with a new container. The whole process realizes the rapid connection of base material supply, auxiliary material addition, stirring and mixing, and finished product discharge, greatly improving work efficiency.

[0045] After the color matching of all the storage barrels 15 is completed, the transverse movement motor 36 drives the screw rod 34 to rotate, driving the moving block 38 to move transversely along the path of the guide rod 35, thereby driving the rotating table 12 to move transversely above the waste water tank 37; then the height motor 310 drives the lifting screw 311 to rotate, driving the linkage plate 312 to descend, and at the same time the linkage plate 312 can drive the side slider 314 to slide along the path of the guide groove 313, so that the hollow water ring 316 is close to the storage barrel 15; the water pump 32 transports water in the water tank 31 to the hollow water ring 316, and the inner wall of the storage barrel 15 and the residual material are washed through the nozzle 317. At this time, the mixing rod 111 and the scraper rod 110 rotate synchronously to assist in cleaning. During the cleaning process, the waste water is discharged into the waste water tank 37 through the discharge valve 113. After completing the single group cleaning, the rotating table 12 is rotated and switched to transfer the next group of storage barrels 15 to the cleaning station.
