For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0021] like Figure 1 As shown, the structure of the automatic color mixing device for painting pigments includes a base 2 for placing a mixing tank 1, a first manipulator 31 and a second manipulator 32 are respectively arranged on both sides of the base 2, a plurality of parallel feeding pipes 41 are arranged at the end of the first manipulator 31, and a filling valve 42 is arranged on the feeding pipe 41; a cylinder cover 51 cooperating with the mixing tank 1 is hoisted at the end of the second manipulator 32, a power shaft 52 is arranged through the middle of the cylinder cover 51, the power shaft 52 is provided with a stirring paddle, a camera 11 and a lighting lamp 12 are arranged on the inner side of the cylinder cover 51, and the first manipulator 31, the second manipulator 32, the filling valve 42, the camera 11, and the lighting lamp 12 are all electrically connected to the PLC controller 6.

[0022] The working principle is as follows: a mixing cylinder 1 is arranged in the base 2 of the device, a first manipulator 31 places a feeding tube 41 at its end above the mixing cylinder 1, and controls each feeding tube 41 to fill materials in sequence through a filling valve 42. After completion, the first manipulator 31 moves away, and the second manipulator 32 moves a cylinder cover 51 at its end to the mixing cylinder 1, snaps it shut, starts a power shaft 52 under the cylinder cover 51, and a stirring paddle starts to stir the mixed materials. During the color adjustment process, the internal stirring condition is observed in real time through a camera 11 and a lighting lamp 12 on the cylinder cover 51 to control the stirring cycle. The equipment is coordinated and linked in a unified manner through a plc controller 6, which saves labor and improves color adjustment efficiency.

[0023] In the structure constituting the above-mentioned automatic color mixing device for painting pigments,

[0024] ——Preferably, an electronic scale 20 is arranged in the base 2, and the feeding pipe 41 is connected to the material tank through a diaphragm pump 43. The electronic scale 20 and the diaphragm pump 43 are electrically connected to the PLC controller 6. The weight of the mixed material in the mixing tank 1 is fed back in real time through the electronic scale 20 to adjust the processing parameters. Since the opening of the canning valve 42 is commanded by the PLC controller 6, when various materials are added in sequence, the opening and closing of the canning valve 42 is adjusted by the value fed back by the electronic scale 20, without setting the opening and closing time of the canning valve 42 in advance, so that the proportion of various materials in the mixing tank 1 is more accurate;

[0025] ——Furthermore, ear shafts 13 are arranged on both sides of the mixing cylinder 1, and the ear shafts 13 are connected to the vertical oil cylinder 14. Frames 71 are arranged on both sides of the base 2, and a plurality of supporting beams arranged side by side are arranged in the frame 71. The supporting beams and the ear shafts 13 are in the same direction, that is, the ear shafts 13 pass through the adjacent supporting beams when they are lifted. A pad 73 driven by a first cylinder 74 is arranged on the side of the frame 71, and the pad 73 is placed between the supporting beams to carry the lifted ear shafts 13 of the mixing cylinder 1. The material filling is completed in the base 2 by the electronic scale 20, and the vertical oil cylinder 14 is started to lift the mixing cylinder 1, and then the ear shaft 13 is placed on the pad 73, so that the mixing cylinder 1 is suspended and fixed, which plays a role in protecting the vertical oil cylinder 14;

[0026] ——The first manipulator 31 and the second manipulator 32 are both composed of a positioning column 301 and a swing arm 302 rotatably arranged at the end of the positioning column 301.

[0027] --like Figure 2 As shown, the power shaft 52 on the cylinder cover 51 includes a transmission shaft 520, and the transmission shaft 520 is connected to the output shaft of the reduction motor 82 through a coupling or a transmission chain. In order to obtain a better stirring effect and improve the color mixing efficiency, a composite stirring paddle structure is selected, which includes a frame 50, and the upper and lower beams of the frame 50 are mounted on the transmission shaft 520. A plurality of paddles 53 are circumferentially installed on the transmission shaft 520. A large-scale stirring is obtained by rotating the frame 50, and the rotation of the circumferential paddles 53 increases the local mixing flow rate, so that the overall mixing and stirring is more balanced;

[0028] - Preferably, a plurality of inclined shovel blades 54 are provided on the side columns of the stirring paddle frame 50 to scrape the cylinder wall to prevent the material from sticking, and the paddle blades 53 on the transmission shaft 520 are inclined in the same direction to increase the material flow rate;

[0029] ——Furthermore, a discharge port with a valve installed is provided at the bottom of the mixing tank 1, and the finished pigment is discharged from the discharge port after the color mixing is completed. A nozzle connected to the cleaning pipeline is provided on the end of the first manipulator 31 or the tank cover 51. After a color mixing process is completed, the nozzle is started to inject the clean water in the cleaning pipeline into the mixing tank 1, and the mixing paddle can be turned on to clean the mixing tank 1;

[0030] ——A hanging block is arranged on the upper part of the cylinder cover 51, and a second cylinder 55 is vertically arranged at the end of the second manipulator 32. The piston rod of the second cylinder is connected to the hanging block, that is, the vertical lifting of the cylinder cover 51 is completed by the second cylinder 55. The cylinder cover 51 and the edge of the mixing cylinder 1 are engaged with each other through the socket boss, so that the mixing cylinder 1 can realize the mixing and coloring process in a closed environment to prevent material spillage and volatilization of odor.

[0031] The above-described implementation modes are only used to illustrate the technical solution of the utility model, and are not limiting conditions for the implementation of the utility model.
