Description
Technical field
The present invention relates to a kind of printer more particularly to a kind of thermal transfer printers.
Background technology
Carbon ribbon is pressed on paper and is beaten by general printer, especially thermal transfer printer, usually print head
Print, in printing, carbon ribbon synchronizes winding, and when printing clear data, print head does not generate heat, but carbon ribbon is wound as usual, and
Carbon ribbon is expendable consumed product, causes carbon ribbon serious waste in this way, increases printing cost.
In addition, in order to ensure printing effect, printing mechanism then must accurately be directed at the print position of paper, so in paper
During Zhang Jinhang is conveyed, it is necessary to carry out the limit on left and right directions to paper, ensure that paper does not occur in transmission process
Offset on left and right directions, it is ensured that printing mechanism can in correct position on printed.
In addition, importantly, print head is fairly expensive, when print head part, such as left side fraction damage, and the right
It is currently unserviceable, directly by the way of replacing print head, this causes very unrestrained when major part can be used normally
Take, increases printing cost.
Invention content
The technical problem to be solved in the present invention is to provide a kind of thermal transfer printer, this thermal transfer printer can avoid
Print clear data when carbon ribbon sky around and cause carbon ribbon to waste, significantly save carbon ribbon, and print head is in the feelings of local damage
Normal print is remained under condition, reduces printing cost.The technical solution of use is as follows：
A kind of thermal transfer printer, including engine base, printing rubber roller, printing head support part, print head, carbon ribbon mechanism, for paper groove,
Paper distributing mechanism and paper advance mechanism are arranged along paper feeding direction on engine base, separation machine successively for paper groove, paper advance mechanism, printing rubber roller
Structure is arranged above paper advance mechanism, and one end of printing rubber roller is equipped with driving gear, and printing head support part is articulated on engine base, print head
On printing head support part, print head is oppositely arranged with printing rubber roller, and carbon ribbon mechanism includes carbon ribbon unreeling shaft, carbon ribbon Scroll
With winding gear, carbon ribbon unreeling shaft, carbon ribbon Scroll are mounted on printing head support part, and winding gear is mounted on carbon ribbon Scroll
One end, winding gear are meshed with driving gear, and the both sides of engine base are respectively equipped with the first fastener, the both sides point of printing head support part
Not She You with matched second fastener of the first fastener, it is characterized in that：Further include at least one elevating mechanism, elevating mechanism
On the side wall of the engine base, at least one first fastener is mounted on the power output end of elevating mechanism；Institute
Paper advance mechanism is stated to include the tapes being arranged on engine base, two pairs of paper feeding nip rolls, include at least two pieces limit partition boards and at least two
Limit adjusting mechanism；Two pieces of limit partition boards are separately positioned on the both sides of tapes；Each limit adjusting mechanism is installed in engine base
Side wall on, the power output end of each limit adjusting mechanism is connected with corresponding limit partition board respectively；On each limit partition board
Offer feed folder roller by notch；The paper distributing mechanism is between two limit partition boards.
Above-mentioned first fastener be generally it is reclinate have contact with, above-mentioned second fastener be generally be bent upwards take
Hook.
The above-mentioned paper for being used to store and supply printing for paper groove.
Above-mentioned paper distributing mechanism is used to separate single paper from for paper groove.
In addition, the transfer passage of paper can also be formed between above-mentioned limit partition board and engine base side wall, paper in engine base and
It limits and also can guarantee the stability in transmission process under the collective effect of partition board.
Above-mentioned paper advance mechanism is used for paper sheet delivery between print head and printing rubber roller.
When wanting printing curve or lteral data, elevating mechanism drives the first fastener to decline, and the first fastener passes through the
Two fasteners pull downward on printing head support part and are downwardly turned over around pivot points, print head, carbon ribbon unreeling shaft on printing head support part,
Carbon ribbon Scroll makes print head be in tangent closed state with printing rubber roller with decline, meanwhile, wind gear and sliding tooth
Wheel is meshed, and driving gear drives carbon ribbon Scroll so that carbon ribbon was wound print head in the following, print head is in paper by winding gear
Figure or word are printed on；When clear data to be printed, elevating mechanism drives the first fastener to rise, the first fastener
Printing head support part is pushed up by the second fastener to be flipped up around pivot points, print head, carbon ribbon on printing head support part
Unreeling shaft, carbon ribbon Scroll make print head be in discrete state with printing rubber roller with rising, meanwhile, winding gear and driving
Gear detaches, and carbon ribbon Scroll stopping acts and makes carbon ribbon pause winding, and print head is directly skipped blank position and waited for next time
Printing curve or lteral data.This thermal transfer printer is directly pacified by adding an elevating mechanism, and by the first fastener
On the power output end of elevating mechanism, the lifting of the first fastener is driven by elevating mechanism, makes print head and printing glue
Roller is in closed state or discrete state, while so that winding gear is in driving gear and engage or discrete state, is detaching shape
Under state, carbon ribbon pause winding, to avoid printing clear data when carbon ribbon sky around and cause carbon ribbon to waste, significantly save carbon
Band reduces printing cost.In the both sides of tapes, respectively one piece of setting limits partition board, from left and right when tapes convey paper
Paper is limited on direction, prevents paper from deviateing during conveying and printing, it is ensured that paper is being conveyed and beaten
Stability during print；When the width of print paper changes or print head local damage needs replacing print position
When, the position of each piece of limit partition board can be changed by adjusting the limit adjusting mechanism of corresponding limit partition board according to printing demand
It sets, so that print head remains to normal print in the case of local damage, reduces printing cost；Meanwhile it is each limit every
Offered on plate for the paper feeding nip rolls by notch, when adjusting the position of limit partition board, also realize to tapes and
Paper feeding nip rolls carries out disposable width adjusting and restriction.In addition, the defeated of paper can also be formed between limit partition board and engine base
Channel is sent, multichannel paper feeding can be carried out at the same time, make full use of print head.
