Description

A kind of efficient positioner of more chromatography ellipse printing machines

Technical field

The utility model belongs to printing machine technical field, is related to a kind of efficient positioner of more chromatography ellipse printing machines.

Background technology

The screen frame of the oval printing machine of the prior art is typically all to be fixedly mounted on total rack, when printing supporting plate is pushing away When running to the lower section of screen frame under into the drive of device along guide rail, propulsion device is out of service, then the print head above screen frame Component declines to be printed with supporting plate pressing, is finished printing rear printhead assembly and is departed from printing supporting plate, printing supporting plate is promoting again Left under the drive of device along guide rail.Its positioner is to control supporting plate and screen frame by controlling the three-dimensional of printing supporting plate to move Relative position.

The positioner of prior art ellipse printing machine is primarily present following shortcoming：This operating type needs to use Discrete control and alignment system carries out one by one come the relative position between the supporting plate below each screen frame screen frame corresponding with being advanced to Positioning, since print head screen frame stent is fixed and stock supporting plate is along guide rail intermittent movement, with the growth of run time With the abrasion of equipment, position error is easily produced, and as the lengthening of assembly line, position error can be amplified by accumulation, and then Printing precision and printing effect are influenced, the printing defects such as ghost image, fuzzy occurs, therefore each print position needs a set of discrete control And alignment system, the cost is relatively high for the control system of complete machine, furthermore, using covering used in discrete control and alignment system more Electronic component it is more, electronic component easily failure or is out of order by external interference, and it is unfavorable that the operation to whole equipment causes Influence.Using effect is preferable not enough.

Utility model content

For overcome the deficiencies in the prior art, the utility model provides a kind of control and alignment system is simple but registration can The efficient positioner of the more chromatography ellipse printing machines leaned on, using effect are more preferable.

The utility model is that technical solution is used by reaching above-mentioned technical purpose：A kind of more chromatography ellipse printing machines Efficient positioner, printing machine include the guide rail in elliptical orbit setting, are erected at guide rail by the distribution of multiple supporting rack spacing Multiple screen frames of top, spacing distribution activity are erected at multiple supporting plates on guide rail, the propulsion device with the drive connection of each supporting plate； Supporting rack is connected by being flexibly connected frame with corresponding screen frame；Be flexibly connected frame on and supporting plate be equipped with can position screen frame with it is corresponding The positioner of relative position between supporting plate；The positioner includes being located at the polylith rectangle contraposition of the lateral surface of each supporting plate Plate, can promote adjustment link and screen frame between X to the X of spacing to pusher cylinder, can promote adjustment link and screen frame it Between Y-direction spacing Y-direction pusher cylinder, adjustment supporting rack can be promoted and the Z-direction promotion gas that is flexibly connected Z-direction spacing between frame Cylinder, be located at screen frame side horizontal square movable positioning plate；Align plate top surface and be equipped with X to positioning groove；Y-direction pusher cylinder When pushing out, movable positioning plate wherein one end it is movable it is interspersed extend into X into positioning groove, while the lateral surface of screen frame leads to Locating pin is crossed with aligning plate medial surface activity to be abutted against；When Z-direction pusher cylinder pushes down on, movable positioning plate bottom surface can be with X to calmly The groove bottom of position groove is abutted against；When Z-direction pusher cylinder pushes up, movable positioning plate bottom surface and aligning plate top side location height phase When；X to pusher cylinder promote to the right when, the right flank of movable positioning plate is abutted against with X to the right side cell wall of positioning groove；Activity is even Connect frame and be equipped with positioning drive roller, screen frame is equipped with positioning belt movable plate, and positioning belt movable plate is equipped with oval positioning and drives groove； Be flexibly connected frame drives roller to drive groove can clutch transmission connection with the positioning of corresponding screen frame by positioning.

The propulsion device is the propulsion device that intermittent fixed length promotes.

The beneficial effects of the utility model are：Due to be flexibly connected frame on and supporting plate be equipped with can position screen frame with it is corresponding hold in the palm The positioner of relative position between plate.Positioner can be in tri- directions of X, Y, Z in a manner of mechanical benchmark snap is aligned Locus between each screen frame and corresponding supporting plate is aligned, since supporting plate is no longer adjusted the movement of polarization, simply Screen frame is moved by the space three-dimensional transmission of machinery by the three-dimensional datum level of setting to be positioned, control alignment system only need to be with opening Pass amount carries out sequential control, and control system is greatly simplified but registration is reliable, efficient, and using effect is more preferable.
