Description
Technical field
The present invention relates to printer field, specifically a kind of lifting mechanism of print head and its method of work.
Background technology
The classification of printing device increasingly refines, and function is also stronger and stronger, the new-type printing such as card puncher occurs and sets
Standby, in the prior art, the printhead of card puncher is fixed in print head mounting bracket, and marking roll drives card transmission, and card exists
In the workflow of printing, while card is transmitted, card is directly tangentially entered between printhead and marking roll, card front end
Edge can to printhead produce impact wear, in addition, card printing when, can simultaneously by printhead and marking roll pressure,
When card exits printhead and marking roll, card back edge produces to printhead and scrapes damage, and printhead is non-in card puncher
Often important part, it is also very expensive, if often impaired, print quality can be had a strong impact on, while reduce printhead significantly
Service life.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of lifting mechanism of print head and its method of work, passed through
The print head mounting bracket that is pushed by the first mounting bracket of support member lifting, is prevented when card from entering or exiting between printhead and marking roll pair
Printhead produces and wears or scrape damage.
The technical solution adopted for the present invention to solve the technical problems：
A kind of lifting mechanism of print head and its method of work, include the print head mounting bracket for being provided with printhead, to printing head
The first mounting bracket that mounting bracket is pushed, support member, the support member are pacified to lift the print head pushed by the first mounting bracket
Shelve.
Further, the support member includes driven supporting plate, driving member and actuator, and the driving member drives driven
Supporting plate is lifted, and the actuator drives driving member to be driven.
Further, the driving member is driven by cam wheel mechanism.

Further, the print head mounting bracket upper end is provided with convex spherical fulcrum, be provided with first mounting bracket and
The bearing point that convex spherical fulcrum adaptation compresses, first mounting bracket are pacified by the cooperation of bearing point and convex spherical fulcrum to print head
Shelve application elastic pressure.
Further, one end of the driven supporting plate is provided with branch turning point, and the other end is provided with convex lift point, the biography
Moving part includes the first cam wheel, and the convex lift o'clock is driven by the first cam wheel, and driven supporting plate lifts around branch turning point
Motion.
Further, the driven supporting plate is provided with suspension mouth in the intraoral side of support, and the roll shaft of marking roll is suspended at
Suspend intraoral, the slot mouth for printing head mounting bracket lower end both sides and being each provided with being adapted to roll shaft.
Further, the slot mouth lower end both sides are each provided with to putting fillet, and the slot mouth is by putting fillet
It is intraoral to support is rested on.
Further, the driving member is provided with to detect the first sensor of the first cam wheel turned position.
A kind of method of work of above-mentioned lifting mechanism of print head, card is put into printer, printhead normality is rise
State, card are sent to print position, and support member drives the print head mounting bracket pushed by the first mounting bracket to decline, printhead pressure
Onto card, printhead prints to card, meanwhile, marking roll drives card to transmit, after card print, support member band
The dynamic print head mounting bracket lifting pushed by the first mounting bracket, printhead depart from card, and card is sent out.
Further, also include second sensor, be sent into distance and print card distance, after card is put into printer, the
Two sensors sense to card, send instruction by second sensor, support member drives the print head pushed by the first mounting bracket
Mounting bracket declines, and after card transmits feeding distance again, printhead is pressed onto on card, and card is printed, and card transmits print again
After card distance, support member drives the print head mounting bracket lifting pushed by the first mounting bracket, and printhead departs from card.
Further, 3rd sensor is also included, after printhead departs from card, card continues to transmit, the 3rd sensing
Device senses to card, confirms that work and logical action are normal.
The beneficial effects of the invention are as follows：Printhead normality is raised configuration, card is put into printer, card is transmitted
To print position, support member drives the print head mounting bracket pushed by the first mounting bracket to decline, and printhead is pressed onto on card, printhead
Card is printed, avoids card from directly tangentially entering between printhead and marking roll and make card front edge to printhead
Produce impact to wear, another aspect, marking roll continuation transfer card, after card print, support member is driven by the first installation
The print head mounting bracket lifting that frame pushes, printhead depart from card, and card is sent out, and avoids card from exiting printhead and printing
During roller, card back edge produces to printhead and scrapes damage, reduces card and wears or scrape damage to printhead, ensures print quality,
Extend the service life of printhead.
