Description
Technical field
The present invention relates to thermal printer technical fields, and in particular to a kind of spliced thermal printing head, printer and peace
Dress method.
Background technique
Thermal printer is to utilize carbon ribbon, in such a way that the carbon dust coating on carbon ribbon is passed through heating by thermal printing head,
It is transferred in paper or other kinds of material.On thermal printer, heat resistant coating directly contacts carbon ribbon with thermal printing head,
Thermal transfer ink is directly contacted with stock (paper or other kinds of material), and thermal printing head moment heat release when work is put
The heat of hot spot sends thermal transfer ink coating to by heat resistant coating and basement membrane, ink melt and by thermoprint to stock,
Form text, image.Thermal printer is transferred using carbon ribbon, and process is also pollution-free without any dust, no liquid, carbon ribbon basement membrane
Ingredient, the carbon ribbon meeting automatic winding printed, recycles.The writing or image printed, can long-term preservation, do not move back
Color will not just wear because of contact solvent, will not result in deforming discoloration etc. because temperature is higher.
But existing thermal printer in the market, print span is narrow, is mainly used in label printing field, maximum
Print span is also no more than A4 paper (300mm) width, therefore cannot achieve the Drawings and documents of printing wide cut.And it can beat on the market
The wide-format printer for printing wide cut Drawings and documents, mainly based on ink-jet and laser；Ink-jet printer, need by prepared Chinese ink at
Picture requires prepared Chinese ink high, easy pipeline blockage and liquid pollution；And laser type printer, ink powder will cause dust dirt
Dye, can also generate ozone pollution, cause harm to the human body.
In order to solve the above-mentioned technical problem, Chinese patent literature (CN102126356A) discloses a physical seams temperature-sensitive and beats
Print head, including installation base plate, longitudinally spaced in the plate face of the installation base plate to offer two mounting grooves, a mounting groove is
Horizontal mounting slot, another is, towards the inclined inclination mounting groove in the horizontal mounting slot direction, three thermal printing heads is distinguished
It is staggered in above-mentioned two mounting grooves along longitudinal direction, for the ease of movement of the thermal print media in print procedure, right
It should be in the horizontal mounting slot of the thermal printing head in inclination mounting groove, and corresponding to the thermal printing head in horizontal mounting slot
Backing plate is provided in inclination mounting groove.
Above patent document is in such a way that multiple print heads splice along longitudinal direction, although solving thermal transfer printer wide cut
Printing there are the problem of, but above-mentioned technical proposal still has following technical problem: being pacified in 1. above patent documents with two
The mode of tankage installs three thermal printing heads mutually spliced, and installation accuracy is lower, can also deposit in practical printing
Splice gap in printing；2. in being printed, being difficult to protect due to inclination splicing setting between two adjacent thermal printing heads
The pressure demonstrate,proved between thermal printing head and print axis is identical, and the stock after will lead to printing generates color not in the direction of the width
Uniform phenomenon, especially stitching portion will appear apparent deep mixed trace.
Summary of the invention
Therefore, the technical problem to be solved in the present invention is that overcome in the prior art thermal printing head splicing precision it is low, with
