Description
Technical field
The present invention relates to a kind of needle type print head microspur adjusting apparatus and method, belong to printing device technical field.
Background technology
Existing impact printer is during flying print, by printing scalp acupuncture impact on colour band, in print media
On clearly print required content.For good print quality, it is necessary to ensure that printhead goes out dial and print media
Between spacing control the error in the range of restriction, usually required that be no more than limit value positive and negative 0.01mm.If printing
Spacing between pin and print media is bigger than normal, then is easily caused the problems such as unintelligible, print needle of printing easily breaks；If print needle
Spacing between print media is less than normal, then print needle after narrowing still with colour band apart from close, then be easily caused print media
There is stain in surface, influences print quality, or even occurs that pin occur scrapes colour band, pulls the failure of colour band, so as to shorten printing
The service life of head and colour band.
Existing technology manually adjusts printhead roller generally by percentage meter reading, clearance gauge or gauge block（Roller is with beating
Print physical contact between media）With print needle identity distance from adjusting printhead spacing.This mode, it is not only cumbersome, waste time and energy,
And because the roller of quality of rubber materials during adjustment is squeezed deformation, causing error larger, the degree of accuracy is not high.
