[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of novel three roller applying structures, it is characterized in that: include the first frame 1, first frame 1 is provided with glue basin 2, be provided with above glue basin 2 vertically arrange successively from the bottom up pass rubber roll 3, metering roll 4, coating pressure roller 5, pass rubber roll 3, metering roll 4, coating pressure roller 5 three roller buses at grade, vertical arrangement, take up space little, unpick and wash conveniently, replacing coating method is easy, described metering roll 4, be provided with between coating pressure roller 5 and be separated pressing structure 6 by first of they separation or pressing, describedly pass rubber roll 3, be provided with metering roll 4 between metering roll 4, coating pressure roller 5 entirety with pass rubber roll 3 be separated or pressing second be separated pressing structure 7, be separated with the first frame 1 and be provided with the second frame 8, be provided with in described second frame 8 and pass rubber roll 3, metering roll 4, the transmission system 9 of three motors formations of coating pressure roller 5 correspondence, first frame 1 at three roll-coater group places and second frame 8 apart arrangement at transmission system and main frame place, eliminate main frame and transmission system motor vibroseis, coating accuracy is high, described three motors with pass rubber roll 3, metering roll 4, connected by Hooks coupling universal coupling 10 between coating pressure roller 5.Hooks coupling universal coupling utilizes the feature of its mechanism, makes diaxon not at same axis, can realize the diaxon continuous rotary connected when there is axis angle, and reliably transmitting torque and motion.The maximum feature of Hooks coupling universal coupling is: its structure has larger angular compensatory ability, and compact conformation, transmission efficiency is high.
Described second separation pressing structure 7 has included and has been provided with metering roll 4, second movable stand 71 of coating pressure roller 5, the second movable stand 71 can be moved up and down to make metering roll 4, coating both pressure rollers 5 entirety and the second cylinder 72 passing rubber roll 3 pressing or be separated, frame 1 is provided with the second guideway 73 that the second movable stand 71 is moved up and down along it, described first is separated pressing structure 6 includes the first movable stand 61 being arranged on and the second movable stand 71 being installed coating pressure roller 5, can pressing or separate measurement roller 4 up and down, first cylinder 62 of coating pressure roller 5, be arranged on the first guideway 63 that the second movable stand 71 makes the first movable stand 61 move up and down along it.First cylinder 62 and the second cylinder 72 are regulated by magnetic valve.
Second movable stand 71 is provided with the first micro-adjusting mechanism 64 of the pressing degree of depth between fine setting metering roll 4 and coating pressure roller 5, described first micro-adjusting mechanism 64 includes the clutch shaft bearing 641 supporting coating pressure roller 5, with the first skewback 642 of clutch shaft bearing 641 times end in contact, horizontally rotate the first accurate lead screw pair 643 that the first skewback 642 can be impelled movable.When the screw mandrel of the first accurate lead screw pair 643 rotates, screw mandrel moves forwards or backwards, and drive the first skewback 642 to move forward and backward, clutch shaft bearing 641, under the supporting role of the first skewback 642, moves up and down.
The second micro-adjusting mechanism 74 that the pressing degree of depth between rubber roll 3, metering roll 4 is passed in fine setting is provided with below the second movable stand 71, described second micro-adjusting mechanism 74 includes the second bearing 741 supporting the second movable stand 71, with the second skewback 742 of the second bearing 741 times end in contact, horizontally rotate the second accurate lead screw pair 743 that the second skewback 742 can be impelled movable.When the screw mandrel of the second accurate lead screw pair 743 rotates, screw mandrel moves forwards or backwards, and drive the second skewback 742 to move forward and backward, the second bearing 741, under the supporting role of the second skewback 742, moves up and down.
The thick metering roll 11 floating with the coating that will pass on rubber roll 3 is provided with above described glue basin 2.Print roll coating imposes coating with applicator roll to coated face, and on-line coater is based on this type of coating machine.Coating weight regulates by metering roll gap pressure, and pressure is strengthened, and the throughput of coating reduces, and coating weight also just reduces.
The course of work: according to technological requirement, driven respectively by transmission system 9 and pass rubber roll 3, metering roll 4, coating pressure roller 5, each roller rotating speed is all adjustable and can rotating.Apply pressure by the first cylinder 62 coating pressure roller 5 is laminated with metering roll 4 along the first guideway 63 or is separated, the pressing degree of depth is finely tuned by the first micro-adjusting mechanism 64.Apply pressure by the second cylinder 72 again coating pressure roller 5, metering roll 4 to be moved integrally and pass rubber roll 3 and be laminated along the second guideway 73 or be separated, the pressing degree of depth is finely tuned by the second micro-adjusting mechanism 74.Be immersed in inside glue basin 2 will be coated with on material strip by passing rubber roll 3, after thick metering roll 11 is floating, is transferred to metering roll 4, then be transferred to substrate surface by metering roll 4 and complete painting process.The pressing degree of depth come between dancer rools and roller by the first micro-adjusting mechanism 64, second micro-adjusting mechanism 74 realizes coating layer thickness size, and also adjustable three rollers speed differ from and turn to regulate coating layer thickness size.By solenoid control cylinder, three rollers can be separated from each other after shutdown.
