Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
As shown in fig. 1 and 2, in one embodiment, the pigment switching method includes: the center control mechanism, the air pressure mechanism 100, the spray gun air supply mechanism 200, the atomization mechanism 300, the spray width mechanism 400, the plurality of pigment conveying mechanisms 500 and the plurality of spray guns 600 further comprise the following steps: the air pressure mechanism 100 is used for conveying air flows for the spray gun air supply mechanism 200, the atomization mechanism 300, the spraying amplitude mechanism 400 and the plurality of pigment conveying mechanisms 500; delivering a gas flow to a plurality of the spray guns 600 through the spray gun gas supply mechanism 200; the atomization mechanism 300 is used for carrying out atomization control on the plurality of spray guns 600; the plurality of spray guns 600 are controlled by the spray width mechanism 400; the paint delivery mechanism 500 of any one of the plurality of paint delivery mechanisms 500 is controlled by a central control mechanism to deliver paint to the corresponding spray gun 600.
When the above-described paint switching method is used, the number of the plurality of paint delivery mechanisms 500 and the number of the corresponding spray guns 600 to be used are determined according to the task of spraying, and different paints necessary for spraying are loaded into the plurality of paint delivery mechanisms 500, respectively. The pigment to be sprayed is determined according to the spraying requirement, and then the pigment delivery mechanism 500 containing the pigment is communicated with the corresponding spray gun 600 (the spray gun 600 connected with the pigment delivery mechanism 500) through the central control mechanism. Meanwhile, the air pressure mechanism 100 is operated, that is, the air supply mechanism 200, the atomization mechanism 300, the spraying width mechanism 400 and the plurality of pigment conveying mechanisms 500 all obtain corresponding air flows. Pigment conveying mechanism 500 can carry pigment to spray gun 600 department under the drive of air current, and spray gun air feed mechanism 200 carries the air current for spray gun 600, then atomizing mechanism 300 and spray width mechanism 400 can carry out spray width control and atomizing control to corresponding spray gun 600 under the effect of air current to make spray gun 600 guarantee spray width and the atomizing degree of spray gun 600 when spraying preset pigment, guaranteed spray gun 600's spraying effect promptly. Further, when the pigment of the spray gun 600 needs to be switched, the pigment conveying mechanism 500 and the spray gun 600 which are communicated before are blocked by the central control mechanism, then the pigment conveying mechanism 500 corresponding to the central control mechanism is communicated with the corresponding spray gun 600 by the central control mechanism according to the pigment needed to be used, meanwhile, the pigment conveying mechanism 500 can be supplied with air by the same set of air pressure mechanism 100, the air flow is conveyed for the spray gun 600 by the same set of spray gun air supply mechanism 200, and the spray amplitude control and the atomization control are carried out on the corresponding spray gun 600 by the same set of atomization mechanism 300 and the same set of spray amplitude mechanism 400. Compared with the traditional mode of manually switching the pigments, the pigment switching method realizes the automatic switching of the pigments, so that the pigment switching is more convenient.
As shown in fig. 2, in one embodiment, in the step of delivering the air flow to the gun air supply mechanism 200, the atomizing mechanism 300, the spraying mechanism 400 and the plurality of paint delivery mechanisms 500 through the air pressure mechanism 100, the air pressure mechanism 100 includes an air compressor 110 and an air filter 120, and the air compressor 110 delivers the air flow to the gun air supply mechanism 200, the atomizing mechanism 300, the spraying mechanism 400 and the plurality of paint delivery mechanisms 500 through the air filter 120. Specifically, the air outlet mode of the air compressor 110 combined with the air filter can ensure that the air outlet of the air compressing mechanism 100 is more stable on one hand, and can also reduce the impurities carried in the air on the other hand.
As shown in fig. 2, in an embodiment, the pigment switching method further includes an air supply pipeline 10, a first air supply branch 20, and a second air supply branch 30, the air supply pipeline 10 is connected to the air pressure mechanism 100, the first air supply branch 20 and the second air supply branch 30 are used to achieve split air flow delivery in the air supply pipeline 10, the first air supply branch 20 is used to deliver air flow to the pigment delivery mechanism 500 and the spray gun air supply mechanism 200, and the second air supply branch 30 is used to deliver air flow to the atomization mechanism 300 and the spray amplitude mechanism 400. Specifically, the air flow output by the air pressure mechanism 100 is received through the air supply pipeline 10, and then two or more branches may be selected to communicate with the air supply pipeline 10 according to actual connection requirements. For example: in this embodiment, the gas flow in the gas supply pipeline 10 may be divided by the first gas supply branch 20 and the second gas supply branch 30. Further, the air pressure used by the pigment delivery mechanism 500 and the air supply mechanism 200 of the spray gun may be different from the air pressure used by the atomizing mechanism 300 and the air supply mechanism 400, so that the pressure regulating valves may be additionally provided on the first air supply branch 20 and the second air supply branch 30, that is, the divided air pressure of the first air supply branch 20 and the second air supply branch 30 may be adjusted according to actual requirements, thereby ensuring the normal operation of the pigment delivery mechanism 500, the air supply mechanism 200 of the spray gun, the atomizing mechanism 300 and the air supply mechanism 400.
As shown in fig. 2, in one embodiment, in the step of controlling any one of the plurality of paint delivery mechanisms 500 to deliver paint to the corresponding spray gun 600 through the central control mechanism, the paint switching method further includes a supply line, the paint delivery mechanism 500 includes a first fluid control valve 510, a diaphragm pump 520, a flow rate proportional valve 530 and a second fluid control valve 540, the diaphragm pump 520 is connected to the first air supply branch 20 through the first fluid control valve 510, the diaphragm pump 520 is communicated with the spray gun 600, the supply line can receive the air flow delivered by the first air supply branch 20, and the supply line delivers paint to the diaphragm pump 520 through the second fluid control valve 540. In particular, the central control mechanism may be a PLC controller or a PC computer. The supply line may be configured to divert the flow of the first air delivery branch 20, and a supply control valve 550 (e.g., SMC control valve) may be added to the supply line to control the flow of paint from the diaphragm pump 520 to the spray gun 600. For example: when one of the paint delivery mechanisms 500 is required to deliver the yellow paint to the spray gun 600, the first fluid control valve 510 (the first fluid control valve 510 for the yellow paint) is first opened, that is, the diaphragm pump 520 can perform suction on the yellow paint by means of the air flow of the first air supply branch 20, and then the flow proportional valve 530 (the flow proportional valve 530 for the yellow paint) and the second fluid control valve 540 (the second fluid control valve 540 for the yellow paint) perform communication between the supply line and the spray gun 600 (the spray gun 600 for spraying the yellow paint), that is, the diaphragm pump 520 is controlled to deliver the paint amount to the spray gun 600 through the supply line. When the color transfer mechanism 500 needs to be replaced with the red color, the first fluid control valve 510 corresponding to the color transfer mechanism 500 for the yellow color is closed, i.e., the communication between the first air supply branch 20 and the color transfer mechanism 500 for the yellow color is blocked. At the same time, the feed line is blocked from communicating with the spray gun 600 by the second fluid control valve 540 for the yellow pigment. Then, the pigment-feeding mechanism 500 for red pigment is connected to the first air-feeding branch 20, and at the same time, the first fluid control valve 510 for red pigment is opened, so that the diaphragm pump 520 can suck the red pigment, and then the supply line is connected to the red pigment spray gun 600 through the flow rate proportional valve 530 for red pigment and the second control valve for red pigment.
As shown in fig. 2, in one embodiment, in the step of controlling any one of the plurality of paint delivery mechanisms 500 to deliver paint to the corresponding spray gun 600 through the central control mechanism, the paint delivery mechanism 500 further includes a return line 40, and the return of the spray gun 600 to the diaphragm pump 520 is realized through the return line 40. Specifically, in order to prevent the paint from being collected at the spray gun 600, when the spray gun 600 finishes spraying, the paint staying at the spray gun 600 may be returned to the diaphragm pump 520 through the return line 40 for recycling.
In one embodiment, in the step of controlling any one of the paint delivery mechanisms 500 of the plurality of paint delivery mechanisms 500 to deliver the paint to the corresponding spray gun 600 through the central control mechanism, the paint switching method further includes a water-oil separator, through which the paint is subjected to water-oil separation. Specifically, the concentration of the pigment may vary due to uncontrollable factors affecting the stored pigment during blending, and thus, the concentration of the pigment for spraying by the spray gun 600 may be too dilute. Therefore, when the pigment concentration does not meet the spraying requirement, the pigment may be subjected to water-oil separation by the water-oil separator, and then the water-oil separated pigment may be conveyed to the spray gun 600 by the diaphragm pump 520.
As shown in fig. 2, in one embodiment, in the step of supplying the air flow to the plurality of spray guns 600 through the spray gun air supply mechanism 200, the spray gun air supply mechanism 200 includes a spray gun air supply line 210, a plurality of spray gun air supply branches 220 and a plurality of solenoid control valves 230, the air flow supplied by the first air supply branch 20 is received through the spray gun air supply line 210, the plurality of spray gun air supply branches 220 are all communicated with the spray gun air supply line 210, and the communication between the spray gun air supply branches 220 and the spray guns 600 is controlled through the solenoid control valves 230. Specifically, when the spray gun 600 needs to perform a spraying operation, the air flow of the second air supply branch 30 is branched through the spray gun air supply pipeline 210, then the air flow in the spray gun air supply pipeline 210 is guided into the air inlet pipeline of the spray gun 600 through the electromagnetic control valve 230, and finally the air flow is communicated with the corresponding spray gun 600 through the air inlet pipeline of the spray gun 600, that is, the spraying power of the spray gun 600 is ensured.
As shown in fig. 2, in one embodiment, in the step of controlling atomization of a plurality of spray guns 600 by the atomization mechanism 300, the atomization mechanism 300 includes an atomization air supply line 310, a plurality of atomization air supply lines 320, and a plurality of third fluid control valves 330, receives the air flow supplied by the second air supply branch 30 through the atomization air supply line 310, communicates with the atomization air supply line 310 through the plurality of atomization air supply branches, and controls the communication between the atomization air supply branches and the spray guns 600 through the third fluid control valves 330. Specifically, when the spray gun 600 needs to perform a spraying operation, the air flow of the second air supply branch 30 is branched through the atomizing air supply pipeline 310, then the air flow in the atomizing air supply pipeline 310 is guided into the atomizing air supply pipeline 320 through the third fluid control valve 330, and finally the air flow is communicated with the corresponding spray gun 600 through the atomizing air supply pipeline 320, that is, the atomizing control of the spray gun 600 is realized.
