Description
Technical Field
The invention relates to the technical field of industrial bar code printing equipment, in particular to a label printer which can avoid the problem of printing faults caused by the bonding of labels and printing parts in the label printing process.
Background
Label printers are widely used in various fields such as factories, warehouses, shops, logistics, transportation and the like, and are used for printing labels with various information such as names, prices, places, models and the like. Such labels are generally self-adhesive labels with a backing adhesive, which are fed into a printer along with a release paper for printing. When the printer normally prints, in order to ensure smooth printing, the printing head and the printing roller (heating roller) need to be tightly attached together through the pressure roller, after the printing work is stopped, because the label paper is continuously printed in a whole roll, the label paper still remains between the printing head and the printing roller and is always pressed on the label paper, and the temperature of the printing roller is higher, the phenomenon that the label paper is bonded with the printing head or the printing roller can be caused, and when the printing is restarted, the problem that paper feeding is stopped and paper jam occurs can be caused.
Disclosure of Invention
To the label paper that current label printer appears when the label printing suspends and beat printer head and take place the problem that bonds, the utility model aims at providing a can avoid label printer that the label bonds completely, guarantee the continuity of work, avoid the printer maintenance of going on repeatedly.
In order to realize the purpose of the utility model, the label printer for avoiding label bonding comprises an upper cover, a printer main body and a power circuit control module, wherein the front of the printer main body is provided with a paper inlet, the paper inlet is provided with a paper feed inductor, two sides of the paper inlet are provided with baffle plates, a printing head is arranged in the printer main body, a pressure roller is arranged above the printing head, and a printing roller is arranged below the printing head; a first roller group for conveying label paper is arranged in front of the printing head, and a second roller group for conveying label paper is arranged behind the printing head; and after the printing process is stopped, the first sensor senses the printing stopping time, and when the printing stopping time reaches a preset time value, the paper withdrawing roller group works to withdraw the label paper positioned between the printing head and the printing roller.
Preferably, the upper cover is provided with an upper cover release button.
Preferably, the baffles arranged on two sides of the paper inlet of the label printer are movable baffles.
The beneficial effects of the utility model are that, label printer set up in original printer and print stop time sensing sensor and paper-withdrawing roller wheelset, after printing and stop a period, automatic will be located and beat printer head and return with the label paper between the print roll, avoid label paper and beat printer head to take place to bond, guarantee to print smoothly, go on in succession, avoid repeated maintenance work.
Drawings
The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings. Wherein:
fig. 1 is a schematic structural diagram of a label printer for preventing label adhesion according to an embodiment of the present invention;
fig. 2 is a schematic view of the inside printing head and the roller set of the label printer of the present invention.
Detailed Description
The structural features, the working process and the advantages of the present invention are described in detail as follows.
Referring to fig. 1 and 2 together, the structure schematic diagram of a label printer for avoiding label adhesion according to an embodiment of the present invention is shown, the label printer includes an upper cover 10, a printer main body 30 and a power circuit control module 20, a paper inlet 31 is provided in front of the printer main body 30, a paper feed sensor 34 is provided at the paper inlet, a baffle 36 is provided at both sides, a printing head 22 is provided in the printer main body 30, a pressure roller 225 is provided above the printing head, a printing roller (rubber heating roller) 223 is provided below the printing head, a first roller set 33 for label paper conveyance is provided in front of the printing head 22, and a second roller set 35 for label paper conveyance is provided at the rear of the printing head; a first sensor 42 is arranged between the printing head 22 and the second roller set 35, and a paper withdrawing roller set 41 and a second sensor 43 are arranged between the printing head 22 and the first roller set 33; the upper cover 10 is provided with an upper cover release button 102 to open the upper cover when a paper jam occurs or the ink cartridge needs to be replaced or the printer needs to be repaired.
The utility model discloses a label printer's working process as follows: when printing is started, label paper enters the printer from a paper inlet, the paper feed sensor 34 senses that the label paper enters, the first roller set and the second roller set rotate to convey the label paper, and the pressure roller presses the printing head down to keep the printing head in contact with the printing roller to perform normal printing; after the printing process is terminated, the first sensor 42 senses the time for terminating the printing, when the printing termination time reaches a preset time value, the driving motor (not shown) of the paper exit roller set 41 drives the paper exit roller set 41 to operate, the label paper between the printing head and the printing roller is returned, when the second sensor 43 senses the label paper is returned, the paper exit roller set 41 stops operating, and when the printer receives an instruction to resume the printing operation, the first roller set and the second roller set rotate to restart the normal printing operation.
In a preferred embodiment, the baffles 36 disposed on both sides of the paper feeding port of the label printer are movable baffles, so that the width of the paper feeding port can be adjusted for label paper with different widths.
The utility model discloses a label printer sets up in original printer and prints pause time sensing sensor and paper-withdrawing roller wheelset, after printing pause a period, and automatic will be located and beat printer head and the label paper between the print roll and return, avoids label paper and beat printer head and take place to bond, guarantees going on smoothly, continuously of printing, avoids the repeated maintenance work.
The present invention is not limited to the embodiments described above, and those skilled in the art can make modifications or changes within the scope of the disclosure without departing from the spirit of the present invention, so that the scope of the present invention is defined by the appended claims.
