Detailed description of the invention
Seeing accompanying drawing, the printing mechanism of set type flexible printing machine in present embodiment, frame is provided with anilox roll 7, roller 8, bottom roller 10 and UV assembly.UV assembly includes solidifying case, UV lamp and blower fan etc., bottom roller and UV assembly cooperating, completes solidification.Roller 8 is rotated by the first power source transmission, and bottom roller 10 is rotated by the second power source transmission, and the first power source and the second power source all include servomotor.Being additionally provided with driven roll 9 in frame, driven roll 9 is between anilox roll 7 and bottom roller 10, and under operating mode, driven roll 9 has coordinated printing with roller 8.Driven roll will be driven by stock (such as paper) and rotate.It is divided among on two rollers completing by printing and two work of solidification, roller can being coordinated with driven roll to complete printing as printing roller, bottom roller coordinating UV assembly complete solidification, even if being stained with ink on driven roll, but can also conveniently not remove through overcuring, as wipes of alcohol can be used to remove.Driven roll is driven by stock and carries out printing work, and driven roll roll surface will keep consistent with the linear velocity of roller roll surface, and printing precision and printing quality will more preferably.
Driven roll is consistent with the external diameter of anilox roll, and the central axis of the central shaft of driven roll and anilox roll is in same plane (plane is preferably horizontal plane), bottom roller is positioned at the right of driven roll, the central shaft of roller is positioned on the plane of symmetry of driven roll and anilox roll, the center of roller may remain on a straight line, and the pressure regulation making roller is convenient.
Anilox roll, roller, bottom roller and driven roll are by arranged in parallel.Roller 8 will be driven by roller lift cylinder 27 and lift.Roller lift cylinder 27 drives roller connecting plate 21 to lift, and roller is connected on roller connecting plate 21 by roller set installing plate 28, and it is sheathed for roller that roller set installing plate 28 has axle sleeve.
CN 204605131 U will carry out pressure regulation to roller.Roller 8 is driven by the first motor 26 and moves axially, and moving axially of roller needs to be limited in an orientation, and does not relate in CN 204605131 U.In present embodiment, roller connects collision block 22, frame is provided with switch base 25 and installs for front limit switch and rear limit switch 23, collision block moves between front limit switch and rear limit switch, and collision block switchs and rear limit switch cooperating with front limit respectively, front limit switch and rear limit switch couple with the first motor respectively.When the first motor-driven roller moves axially back and forth, collision block synchronizes movable with roller, and when collision block touches front limit switch or rear limit switch when, front limit switch or afterwards limit switch actuating signal make the first motor quit work.
The roller 8 during printing work shaft shoulder before and after it is rested the head on by the roller of semicircular ring shape and is supported, the roller pillow of semicircular ring shape, semicircular ring shape can be 1/2 annulus can also be more smaller than 1/2 annulus.Roller pillow floating is located in frame, respectively arranges a roller pillow, is provided with pressure regulation support arm 13(and includes left pressure regulation support arm and right pressure regulation support arm below roller pillow).Left pressure regulation support arm and right pressure regulation support arm all swing and are arranged in frame, the swing pivot of each pressure regulation support arm is each provided at their upper end, and left pressure regulates support arm and right pressure regulation support arm is equipped with corner arc sections and supports roller pillow.The center of corner arc sections of left pressure regulation support arm is with the center of anilox roll for being arranged concentrically, and right pressure regulates the center of corner arc sections of support arm with the center of driven roll for being arranged concentrically.Each pressure regulation support arm is by being furnished with support cylinder 14 and regulation motor 1 and by supporting cylinder and regulation motor coordinates and drives it to swing in frame.Support cylinder to be connected with pressure regulation support arm by support rod 15.The floating that band action roller is rested the head on by the swing of left pressure regulation support arm and right pressure regulation support arm, thus reach to regulate roller pressure.Bilateral symmetry, the pressure regulation making roller is convenient.
Each pressure regulation support arm is provided with zero position switch 17, and zero position switch 17 is arranged in frame by mounting seat 16.Zero position switch regulates supporting arm triggering with the pressure of pairing and coordinates, and pressure regulation supporting arm can arrange briquetting 18 and coordinate with zero position switch.Zero position switch can use touching to switch, and carries out triggering cooperation by touching, or uses position sensor, carries out triggering cooperation by position sensor.Each zero position switch is arranged in frame, and each zero position switch couples with controlling device, controls device and couples with each regulation motor, and each zero position switch is corresponding with the regulation motor of each pressure regulation support arm pairing respectively.Set the initial position of each pressure regulation support arm by arranging zero position switch, promptly each pressure regulation support arm is returned to initial position during convenient regulation, in order to again roller is carried out pressure regulation.The when that regulation motor working and coordinates support cylinder band dynamic pressure regulation support arm to swing, when pressure regulation support arm triggers zero position switch when, for initial position (i.e. zero-bit), now, controlling device and will receive the signal of zero position switch, then control device just can control corresponding regulation motor and carry out new pressure regulation work, is adjusted from initial position, regulation motor can use common electric machine, and cost is lower.
Frame 5 is provided with the first semicircular ring bearing block, swinging mounting 4 and bracket locking device, swinging mounting swings setting in frame, swinging mounting is provided with the second semicircular ring bearing block, first semicircular ring bearing block and the second semicircular ring bearing block coordinate to be installed for anilox roll, second semicircular ring bearing block supports anilox roll in swinging mounting swing process all the time, semicircular ring can be 1/2 annulus can also be more smaller than 1/2 annulus.Bracket locking device includes locking cylinder 3 and latch segment 55, locking cylinder drives latch segment action, and when swinging mounting is with anilox roll to Working pasition, swinging mounting is pinned in latch segment action, can arrange pin on swinging mounting, latch segment can act on pin when pinning.
