Description
Technical field
The utility model relates to a kind of screen printer of drum-type, refer to that a kind of free-standing drive unit of many groups that adopts drives printing cylinder and half tone carrier to carry out the drum-type screen printer of wire mark operation respectively especially, reduce numerous and diverse design and interference problem in mechanism, overall structure can be reached and simplify and increase printing precision.
Background technology
Tradition mechanical type screen printer is mainly driven by a central motor, and drives charger (feeder), feeding table charger (infeed table feeder), side alignment device (side alignment device), printing cylinder (print cylinder), half tone carrier (screen carrier) and sheet stock carrying device (sheet delivery device) respectively by the rotary motion of described central motor.
Wherein, the free gear of the Direct driver axis of centres and cylinder axis left and right sides forms transmission means jointly, and free gear through tooth bar from both sides drive half tone carrier carry out advances print action or after return black action.
But, this kind of screen printer is mainly subject to the Accuracy of synchrodrive tool between half tone carrier and printing cylinder, because the axis of Mechanical Driven mainly through cylinder is left, the two groups of gear trains in right side are connected to each other with half tone carrier and engage, because connection between gear can make a variation because of different rotation rates, therefore the printed article of cylinder surface rotation and the operating position between the half tone carrier of cylinder upper horizontal movement is fixed on, each synchronization accuracy put instantaneously requires very high, and long time running will cause gear to wear away gap increasing, if synchronization accuracy does not reach requirement, generation recoil backlash is caused print pattern misalignment.
Another kind of mechanical type screen printer mainly adopts and rests formula cylinder principle, common head roll is carried out through printing cylinder both sides half tone shifting apparatus (such as: both sides tooth bar), both sides tooth bar is made to form separately a contact point, therefore precise synchronization between half tone shifting apparatus and printing cylinder, and can not affect by print speed printing speed and inertia.
But, though this kind rests the screen printer of formula cylinder and can reach high-precision requirement, but because cylinder adopts 360 degree of rotations, and half tone carrier only small distance move horizontally, therefore in fact use the deviation being still and being difficult to control half tone and rolling amount of movement, the movement will reaching restriction half tone carrier on mechanical type screen printer can independent of the action of printing cylinder, completely impossible especially.
Therefore, then the screen printer being separated servo-drive is had to come out, refer to shown in Fig. 1 and Fig. 2, the screen printer that tradition is separated servo-drive mainly completes drive actions via electronic type Synchronization Control, comprise a drive charger 101, first drive source 10 of feeding table 102 and side alignment device 103, second drive source 11 of one drive printing cylinder 111 and rotating shaft 112, one drives the 3rd drive source 12 of half tone carrier 121 and the four-wheel drive source 13 of a drive discharging conveyor belts 131, wherein, described 3rd drive source 12 drives described half tone carrier 121 left through the gear 123 of transmission both sides, axle center 122, the gear 124 of right both sides.
But, the half tone carrier of this kind of servo-drive screen printer is still and connects mutually with gear 123,124, still can produce recoil or buffering backlash each other, therefore, precision to be maintained at ± 0.03mm within the scope of various friction speed, still cannot reach with current existing servo-drive design.
And no matter adopt which kind of mode aforementioned, the structure of screen printer not only complicated (comprising multiple sets of teeth wheel, tooth bar, cam and chain) to cause in assembling more work consuming, consuming time, and the tolerance that part itself exists cannot be avoided, therefore, part is more by higher for the numeral causing tolerance cumulative, cannot reach the precision of demand.
