Described elevating mechanism can be hydraulic cylinder, cylinder or motor-driven screw pair etc.
Scraper, loading tray are all furnished with independently elevating mechanism.
Get liquid roller and be responsible in process of production from loading tray, taking up coating (masking liquid) and transferring on metering roll, get liquid roller according to different coating methods and can use hard chrome plating smooth roll, anilox roll or rubber roll; Metering roll is by making the roll surface wet feed of coating obtain needed thickness, arrangement and homogenising with the extruding of getting liquid roller, and metering roll can be used hard chrome plating smooth roll or anilox roll; Applicator roll is to be responsible for pushing uniform pigment transfer to band steel, uses rubber roll.
The first applicator roll 1 and the first metering roll 2, the first metering roll 2 and first is got liquid roller 3, the first metering roll 2 and second is got liquid roller, the second applicator roll 8 and the second metering roll 9, the second metering roll 9 and the 3rd is got liquid roller 10, the second metering roll 9 and the 4th is got liquid roller 11, can carry out separately respectively roll gap, roll gap pressure adjusting, thereby can meet the requirement to roller coat thickness under different process speed between each roller.
Loading tray is welded by steel plate is assembled, and bottom is provided with elevating mechanism (or claiming apparatus capable of fluctuating), and in the time changing painting color, loading tray is down to device bottom, can realize the replacing of carrying out painting color in the situation that not affecting normal production.The first loading tray 5, the second loading tray 6 are responsible for respectively getting liquid roller 3, second to first and are got liquid roller 4 and carry out feed; The 3rd loading tray 12, the 4th loading tray 13 are responsible for respectively getting liquid roller 10, the 4th to the 3rd and are got liquid roller 11 and carry out feed; Scraper is the assembling of available common doctor's cutter, is arranged and metering roll under, and there is vertically liftable function.The first scraper 7, the second scraper 14 respectively with the first metering roll 2, the second metering roll 9 corresponding matching, its surperficial remaining masking liquid is removed.
Running part is made up of shaft coupling and motor, motor by shaft coupling respectively with applicator roll, metering roll, get liquid roller and be connected, realize the adjusting to each roller rotating speed by control.
The course of work of this roll coater is as follows:
1, before threading, require to adjust the first applicator roll 1 and the first metering roll 2 according to technological parameter, the first metering roll 2 and first is got liquid roller 3, the second applicator roll 8 and the second metering roll 9, the second metering roll 9 and the 3rd is got liquid roller 10, roll gap between each roller and roll gap pressure size, now the first metering roll 2 and second is got liquid roller 4, the second metering roll 9 and the 4th loading tray 13 are in released state, the first loading tray 5, the in-built coating that has required coating color of the 3rd loading tray 12, steel threading to be with completes, when normal production, running part is started working, by the pressure between each roller and poor cooperation of speed masking liquid being transmitted, the most required masking liquid Tu is to being with two surfaces of steel.
2, if need to change in process of production the coating color of steel plate, receiving after order, the first loading tray 5, the 3rd loading tray 12 is dropped rapidly to can not supply with the fixed position of getting liquid roller coat material, the first scraper 7, the second scraper 14 rises to the first metering roll 2, the working position that the roll surface of the second metering roll 9 is removed remaining masking liquid, get liquid roller 3 by regulating the first metering roll 2 and first, the first metering roll 2 and the first applicator roll 1, the second metering roll 9 and the 3rd is got liquid roller 10, roll gap between the second metering roll 9 and the second applicator roll 8, can realize remaining masking liquid is brought to metering roll, removed clean by scraper.After remaining masking liquid is removed totally, the first scraper 7, the second scraper 14 are down to low level, the first metering roll 2 and second is got liquid roller 4, the second metering roll 9 and the 4th is got liquid roller 11 and is coordinated rapidly, and regulate roll gap, the second loading tray 6, the 4th loading tray 13 also rise to rapidly the position that can supply respectively the first metering roll 2, the second metering roll 9 masking liquids, start normally to produce.Thereby can realize non-stop-machine situation quick-replaceable painting color at the scene, enhance productivity.
