Then, the lifting drive device 360 ​​drives the lifting slide plate 361 to move downward, and the pistons 352 of each pump valve 33 will move downward along the piston cylinder 350, and the paint in the corresponding storage tank 20 will be drawn into the corresponding piston cylinder 350. When the paint in the piston cylinder 350 needs to be output to the container, the input / output control mechanism 341 first controls the piston cylinder 350 to connect with the output end 340b, and the piston cylinder 350 will disconnect from the input end 340a. Then, the lifting drive device 360 ​​drives the lifting slide plate 361 to move upward, and the pistons 352 of each pump valve 33 will move upward along the piston cylinder 350, and the paint in the corresponding piston cylinder 350 will be output to the container through the discharge port 410. By controlling the operation of the input / output control mechanism 341 of each pump valve 33, the on / off state of the piston cylinder 350 with the input end 340a and the output end 340b can be controlled, thereby controlling each pump valve 33 to perform feeding or discharging operations, realizing automatic color matching, accurately controlling the paint output, improving color matching accuracy, and having the advantages of simple structure and convenient maintenance, which can reduce equipment costs.

The pump body module 35 also includes a connecting sleeve 353 fixedly connected to the bottom of the valve body 340. The piston cylinder 350 is threadedly connected to one end of the connecting sleeve 353. The valve plate 341m is movably disposed inside the connecting sleeve 353. Specifically, when the first motor 341b is working, it will drive the valve plate 341m to rotate, which will allow the first sector-shaped through hole 341n to connect with the first sector-shaped channel 340c or the second sector-shaped channel 340d.When paint needs to be stored in the piston cylinder 350, the first motor 341b drives the valve plate 341m to rotate, so that the first sector-shaped through hole 341n is connected to the first sector-shaped channel 340c, and the second sector-shaped channel 340d is separated from the piston cylinder 350. By driving the piston rod 351 to move downward, the piston 352 will move downward along the piston cylinder 350, and the paint in the storage tank 20 will be drawn into the piston cylinder 350 in sequence through the discharge port 200, the input end 340a, the first sector-shaped channel 340c, the second sector-shaped through hole 341e, and the first sector-shaped through hole 341n.

When the paint in 350 is output into the container, the first motor 341b drives the valve plate 341m to rotate, so that the first sector-shaped through hole 341n and the second sector-shaped channel 340d are connected. The first sector-shaped channel 340c will be separated from the piston cylinder 350. By driving the piston rod 351 to move upward, the piston 352 will move upward along the piston cylinder 350. The paint in the piston cylinder 350 will be pushed into the container in sequence through the first sector-shaped through hole 341n, the third sector-shaped through hole 341f, the second sector-shaped channel 340d, and the output end 340b. By controlling the movement stroke of the piston rod 351, the flow rate of the paint output into the container can be controlled.

When the first sensing plate 341j enters the sensing area of ​​the first slotted photoelectric switch 341k, the valve plate 341m rotates to the position where the first sector-shaped through hole 341n and the first sector-shaped channel 340c are connected; when the first sensing plate 341j enters the sensing area of ​​the second slotted photoelectric switch 341l, the valve plate 341m rotates to the position where the first sector-shaped through hole 341n and the second sector-shaped channel 340d are connected, thus realizing the control of the rotation angle of the valve plate 341m.

The horizontal drive mechanism is used to drive the horizontal slide plate 421 to move. A through hole is provided through the second pad 420, and one end of the discharge port 410 communicates with the through hole. When it is necessary to discharge paint into the container, the horizontal drive mechanism is used to drive the horizontal slide plate 421 to move backward, so that the dustproof cover 422 can retract to open the through hole, and the paint discharged from the discharge port 410 can fall into the container. In the non-use state, the dustproof cover 422 can close the through hole to prevent dust from contaminating the discharge port 410.

[0039] Based on the above embodiments, the horizontal drive mechanism includes a second motor 423 mounted on the pallet 40, a rack 424 fixedly connected to the horizontal slide plate 421, and a gear 425 connected to the output shaft of the second motor 423 and meshing with the rack 424. When the second motor 423 is working, it drives the gear 425 to rotate.

The discharge platform 5 is fixedly connected to one side of the Z-axis sliding plate 500. Several fixed pulleys 505 are rotatably connected to the machine body 1.

The height positioning mechanism 51 includes a positioning column 510 fixedly connected to the machine body 1 and an elastic pin assembly. The column 510 has equally spaced insertion holes 510a arranged side by side along its length. The bottom of the discharge platform 5 is provided with a baffle 511, a first connecting plate 512, and a second connecting plate 513. The elastic pin assembly includes a first connecting rod 514 hinged to the baffle 511, a second connecting rod 515 hinged to one end of the first connecting rod 514, a pin 516 hinged to one end of the second connecting rod 515, a limiting ring 517 sleeved on the pin 516, and a spring 518 sleeved on the pin 516. The first connecting plate 512 and the second connecting plate 513 are both provided with guide holes that match the pin 516. The pin 516 is movably disposed between the two guide holes. The spring 518 abuts against one end face of the limiting ring 517 and one side face of the first connecting plate 512. One end of the pin 516 is inserted into one of the insertion holes. Specifically, when the height of the discharge platform 5 needs to be adjusted, first pull the pin 516 backward to pull it out of the insertion hole 510a, and then drive the discharge platform 5 to move up and down. The Z-axis sliding plate 500 will move up and down. Since the steel rope 503 is connected between the Z-axis sliding plate 500 and the pulley box 502, the two ends of the steel rope 503 achieve the effect of tension balance, making it easier to adjust the height of the discharge platform 5. After the discharge platform 5 is adjusted to the required height, the pin 516 will be aligned with the insertion hole 510a at the current height of the positioning column 510. After releasing the pin 516, the pin 516 will be reset under the elastic force of the spring 518 and inserted into the insertion hole 510a at the current height of the positioning column 510, thus realizing the positioning of the discharge platform 5.
