Description

Technical Field

[0001] The invention relates to a field, and in particular to an intelligent color matching system based on solvent-based color paste. Background Art

[0002] Color matching is an indispensable process in the production and application of paints. At present, color matching is basically done manually. With the increasing labor costs and customer requirements, the defects of traditional manual color matching, such as cost, accuracy, randomness, and easy loss of color matching data, are immediately exposed. It has become very necessary to develop an intelligent color matching system and solvent-based color pastes for intelligent color matching systems suitable for machine color matching.

[0003] Solvent-based colorant: It uses organic solvent as the medium, with high-concentration pigments plus resins, dispersants and other additives through formula optimization and combination, and is carefully prepared through special processes and grinding equipment. The colorants used in existing color matching systems are mainly water-based colorants and traditional solvent-based ordinary colorants. The color concentration, color stability, batch stability and other indicators of their products do not meet the requirements of the use of intelligent color matching systems.

[0004] After extensive searching by our team, we learned that the existing color matching system is not very accurate because the existing intelligent color matching system mainly uses a screw module to push the compression space to achieve the discharging mode. With the improvement and replacement of solvent-based color pastes, this mode of system can no longer meet the needs, so it is necessary to develop a color matching system suitable for new color pastes.

[0067] How to operate:

[0068] Input instructions; place the material container at the positioning mark position, and input the volume of various color pastes to be added through the display control screen;

[0069] Conversion; after the operation starts, the first drive motor needs to transfer the storage tank from which the material is to be discharged to the active position;

[0070] Batching: Control the batching module to operate, deliver a set amount of gas to the storage tank in the active position, so that the color paste in the storage tank is squeezed out from the discharge port, and extrude a set amount of color paste each time until the total amount of extrusion reaches the set amount;

[0071] The specific steps of the batching step are: the control module controls all the second control valves to be closed, the first control valve remains open, and then the air pump starts to operate to inflate the balloon of the supply detection unit, and the balloon gradually becomes larger until the pressure sensor of the supply detection unit monitors that the pressure of the balloon reaches the set value, and then controls to close the first control valve, and at the same time the air pump stops operating, and then opens the second control valve in the active position, and the balloon presses the gas into the storage tank due to its own elasticity, so that the color paste in the storage tank is pressed out from the discharge port to the storage container, and the above conversion and batching steps are repeated until the addition is completed according to the input scheme;

[0072] Adding materials; when the monitoring module detects that the color paste capacity in the storage tank is lower than the observation window at the bottom, the control module prompts to replenish the color paste through the display control screen display signal, and the operator selects the working mode of the device as the adding mode in the display control screen, so that the baffle mechanism operates to block the feeding port, and then controls to open the first control valve and the second control valve corresponding to the active position, so that the air in the discharge tank can flow back to the air pump, the operator opens the top cover, and then aligns the bag mouth of the color paste filling bag with the connecting protruding nozzle for threaded connection, and then rotates the color paste filling bag so that the ejector pierces the sealing film, squeezes the color paste filling bag so that the internal color paste presses the pressing block down and flows into the storage tank, and the feeding can be realized. After the feeding is completed, the color paste filling bag is detached so that the feeding port is restored to closure, and then the baffle module is controlled to leave and return to its position, and the operation of the batching step is controlled to inflate the storage tank, and observe whether there is color paste flowing out, so that the color paste is filled to the discharge port, and the batching module can be closed, and the feeding is completed;
