Description
Technical field
This utility model belongs to printer technology field, and in particular to a kind of print head structure and its printer.
Background technology
Label machine is to be printed upon bar code, Quick Response Code, figure, word are printed on label using temperature-sensitive, thermal transfer mode
Etc. the equipment of various image informations, it is used widely in fields such as POS terminal system, banking system, Medical Instruments.
Existing label machine has to the guide frame for carbon ribbon and label.Prior art be printing head support part with it is rear
The carbon ribbon leading truck of side is all integral type structure, there is problems with：1. label is moved in the space of a fixed interval (FI), and
As label body is software, it is impossible to smoothly move in space, therefore can be relatively upper and lower in this space in motion is printed
Float so that its it is inconsistent with the distance of induction apparatuss normally cannot detect, it is inaccurate to cause to print detection, print position occurs not
Standard, the inaccurate phenomenon of off-position；2., for the different-thickness of label, no matter the thickness of label is how many, and its gap width is permanent
Fixed, this brings unfavorable to detecting label；3. the guiding of integral type also has two kinds of forms of expression：Led with the sheet metal on printhead
To；To installation metal guide post before printhead.Sheet metal is oriented to and metallic rod is oriented to and all there was only guide function without platen
Function, therefore accuracy of detection can not be improved；Meanwhile, improve assembling and manufacture complexity using metallic rod, be unfavorable for production.
Existing printhead can fluctuate, but front and back position can not be moved, and adaptability is poor：Printhead is printer
Most critical part, its installation site are extremely important, therefore which can return to correct installation site under folding condition to printing
Effect is directly related.Due to the error assembled, if only with fluctuating, printhead can not very quick return to locking position, or enter
Enter locking position to have some setbacks, the method for improving its effect is to improve assembling and the accuracy of manufacture of center of rotation, generally uses exclusive clamps
Have to install, mounting structure is complicated, operation inconvenience.Conventional printer, in order to meet the printing requirement of different-thickness label, passes through
The copper sheathing of different size diameter is changed adjusting the pressure value of printhead, be difficult to change, the copper sheathing of different-diameter it is not portable, easy
Lose.
