A kind of paper reverse bending switching mechanism and printer
Technical field
The present invention relates to the technical field of label machine, particularly relate to a kind of paper reverse bending switching mechanism and printing
Machine.
Background technology
Label machine is to use temperature-sensitive, thermal transfer mode to print bar code, Quick Response Code, figure, word etc. on label respectively
Plant the equipment of image information.At the placement space of label machine design paper roll, for paper roll is accommodated in printer, and
Label outlet is set on label machine shell.During use, along with the continuous minimizing of label coil paper, the closer to label coil paper
Center, the label bow degree of output is the biggest, brings inconvenience to use.
Owing to bottomless paper label has viscosity, easily bond with print member.And label paper is repeatedly bent or is exported
When having some setbacks, the base stock of label paper is easily stripped.Therefore, be not suitable for using anti-bending mechanism without base stock or label paper.And
During printed tickets paper, user is often desirable to use and reversely bends component so that the check paper of output is straight, conveniently take,
Signature etc..In existing technology, it is to use change whole printer core or need to use different label machines to solve
This problem, needs to lay in more printing device, and operation is inconvenient for.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, it is provided that a kind of paper reverse bending switching mechanism.
Solution problem is, first, after the size of printing paper roll reduces, the label bow degree of output is big, the taking of label,
Checking that the check paper that all inconvenient problem, the such as place such as supermarket, bank print needs signature, the bill rolled is inconvenient to take
Take and sign on bill;Secondly, having viscosity without base stock and be easily bonded on recurvation folded structure, label paper is repeatedly bent
Or when output has some setbacks, the base stock of label paper is easily stripped.Cause printed tickets paper and print without base stock, label paper, need
Distinct device to be used, the problem of troublesome poeration.
For solving above-mentioned technical problem, present invention employs techniques below measure:
A kind of paper reverse bending switching mechanism, is used for being located at printer body, including recurvation folding component and switching member,
Component is rotating is located in printer body for described recurvation folding, and one end of described recurvation folding component is provided with connection post;Described cut

To roll shaft;When needing recurvation folding component, stirring switch piece, recurvation is rolled over component and is rotated up, described paper roll is extracted out and is guided successively
To guiding roll shaft, recurvation folding component, rubber roll;When need not recurvation folding component, stir switch piece, component is rolled in recurvation and turns downwards
Dynamic, described paper roll passes from recurvation folding component and the gap guided between roll shaft, guides subsequently to rubber roll.
Compared with prior art, the invention have the advantages that
1, drive the rotation of recurvation folding component by arranging switching member, as required recurvation can be rolled over component and be located at not
Same position, meets different use demands.When printed tickets paper, component is rolled in recurvation and is rotated up, use anti-bar folder
Structure;And when printing without base stock or label paper, anti-bending mechanism is rotated down, it is to avoid paste on anti-bending mechanism without base stock
Or the base stock of label paper is stripped.Make a printer can apply to different paper, have be widely used, easy to operate
Advantage.
2, coordinated with the driving section of connector by the arcuate groove on switch piece, enable connector to move up and down.And with
Time, connector arranges level trough be connected post connect.Make connection post at vertical direction and the uniform mobile space of horizontal direction,
Realize the rotating function of recurvation folding component.By switch piece, the transmission fit structure of connector, realize recurvation by stirring action
The rotation of folding component.There is easy to operate, practical advantage.
3, by being respectively provided with left self-locking section, right self-locking section at the two ends of arcuate groove so that two shapes of recurvation folding component
Position relationship under state is stable, it is to avoid the state of recurvation folding component arbitrarily converts, and impact uses.
4, by anti-bending mechanism, the opposite direction that label coil paper bends towards label coil paper is bent so that the label of output
The most open and the most flat, conveniently take and check.
