Abstract
A hand-lifting printing head of a thermal transfer coding machine comprises the printing head, and is characterized in that the printing head further comprises a printing head bracket and a working cylinder, wherein the printing head is mounted on the printing head bracket, and the printing head bracket is in hinge joint with a piston push rod of the working cylinder and is limited on the piston push rod through a mechanical limit switch. By applying the hand-lifting printing head, not only the demand of customers in replacing ink-ribbons is met, but also the problem of the prior mode of ink-ribbon cartridges as well as the inconvenience of replacing ink-ribbons without ink-ribbon cartridges are solved.
Description
Technical field
The utility model relates to the hot transfer printing coder technical field of industry spot, particularly a kind of hot transfer printing coder manually lift printhead.
Background technology
At present, the application of the hot transfer printing coder of intelligence on can of single track formula and packing machine is more and more general, the hot transfer printing coder major part of external import all adopts the mode of the ribbon cartridge band of checking colors to change, though have only the machine of minority not use ribbon cartridge. ribbon cartridge can improve the efficient and the accuracy of the more replacing of Ribbon Change greatly, but owing to adopted ribbon cartridge, the appearance and size of machine will be improved widely, the design difficulty of mechanical part, the precision of machined piece has also increased the cost of equipment component.Do not adopt at present the hot transfer printing coder of ribbon cartridge mode, because being subjected to printhead and colour band peels off the restriction of the angle of axle and makes more the Ribbon Change very difficulty that becomes, make the replacing of colour band take long time, reduced the efficient of production line, simultaneously owing to increased the possibility that the printhead abnormal operation damages.
The utility model content
Technical problem to be solved in the utility model is to change the not problem of aspect at existing hot transfer printing coder colour band, and a kind of hot transfer printing coder proposed manually lift printhead, to realize manually lifting printhead, the function that makes things convenient for colour band to change.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of hot transfer printing coder manually lift printhead, comprise printhead, it is characterized in that, also comprise a print head carriage and a working cylinder, described printhead is installed on the print head carriage, and described print head carriage is connected with the piston push rod hinge of working cylinder and is limited on the piston push rod by mechanical limit switch.
Described mechanical limit switch comprises by the switch arm of torsion spring hinge on piston push rod.
Described working cylinder connects an oily magnetic valve, and this magnetic valve is electrically connected with the master control borad of hot transfer printing coder.
The angle that the utility model is peeled off axle according to the operation principle and the colour band of thermal printing head, and the winding path of whole colour band, printhead is divided into three positions, be in meta during standby at ordinary times, need cylinder that printhead is pushed out to low level during print job, to finish printing, switching between these two positions is controlled by master control borad, when needs more during Ribbon Change, with manual mode the switch arm of the mechanical limit switch between print head carriage and the piston push rod is pushed aside, light print heads rotatable carriage, the print head carriage is rotated around hinge point, thereby make print head position be raised to the top of colour band transition roller, the spacing that printhead and colour band are peeled off between centers strengthens, the angle that this moment, colour band must be not any, just simply pass in straight mode, more behind the Ribbon Change, go back to the print head carriage, thereby make the print head carriage be returned to meta, at this moment the switch arm of mechanical limit switch return under the promotion of torsion spring, the position of print head carriage is limited, and the printhead that makes can only switch between meta and low level, has guaranteed that simultaneously printhead and colour band peel off the angle of the requirement of between centers.The needs of client when Ribbon Change have more not only been satisfied in the application of this mechanism, have more solved the problem of existing ribbon cartridge mode, and the inconvenience that do not have the more Ribbon Change under the ribbon cartridge situation.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings:
Fig. 1 is the schematic diagram of the printhead of hot transfer printing coder of the present utility model when being in meta and low level (dotted line is that printhead is when being in a high position among the figure).
Fig. 2 is the connection block diagram between the utility model master control borad, magnetic valve and the working cylinder.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of hot transfer printing coder manually lift printhead, comprise printhead 10, print head carriage 20 and a working cylinder 30, printhead 10 is installed on the print head carriage 20, and print head carriage 20 is connected with the piston push rod hinge of working cylinder 30 and is limited on the piston push rod by mechanical limit switch 40.This mechanical limit switch comprises by the switch arm (not shown) of torsion spring hinge on piston push rod.
Referring to Fig. 2, working cylinder 30 connects an oily magnetic valve 50, and this magnetic valve 50 is electrically connected with the master control borad 60 of hot transfer printing coder.
The angle that the utility model is peeled off axle 70 according to the operation principle and the colour band of thermal printing head, and the winding path of whole colour band 90, printhead is divided into three positions, be in meta during standby at ordinary times, need working cylinder 30 that printhead 10 is pushed out to low level during print job, to finish printing, switching between these two positions is controlled by master control borad 60, when needs more during Ribbon Change 90, with manual mode the switch arm of the mechanical limit switch between print head carriage 20 and the piston push rod 40 is pushed aside, light print heads rotatable carriage 20, print head carriage 20 is rotated around hinge point, thereby make print head position be raised to the top of colour band transition roller 80, the spacing that printhead 10 and colour band are peeled off 70 on axle strengthens, the angle that this moment, colour band 90 must be not any, just simply pass in straight mode, more Ribbon Change is after 90s, go back to print head carriage 20, thereby make print head carriage 20 be returned to meta, at this moment the switch arm of mechanical limit switch 40 return under the promotion of torsion spring, the position of print head carriage 20 is limited, the printhead that makes can only switch between meta and low level, has guaranteed that simultaneously printhead 10 and colour band peel off the angle of requirement of 70 on axle.The needs of client when Ribbon Change have more not only been satisfied in the application of this mechanism, have more solved the problem of existing ribbon cartridge mode, and the inconvenience that do not have the more Ribbon Change under the ribbon cartridge situation.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
