Description

Improved label printer capable of avoiding label adhesion

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 is still left 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 label paper and the printing head can be bonded, when the printing is restarted, the problem of paper jam caused by paper feeding stagnation can be generated, the stagnation of the printing work is caused, the machine needs to be repeatedly stopped for maintenance, and the working efficiency is low.

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 label printer that modified can avoid the label bonding completely, guarantees the continuity of work, avoids the printer maintenance of going on repeatedly.

In order to realize the purpose of the utility model, the utility model discloses an improved 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 printer main body are provided with baffle plates, a printing head is arranged in the printer main body, a pressure roller is arranged above the printing head, 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 at the rear of the printing head; a first sensor is arranged between the printing head and the second roller group, and the printing head is connected with a position return component which is connected with a fixed structure on the printer main body; after the printing process is stopped, when the first sensor senses that the printing stopping time reaches a preset time value, the pressure roller returns to the original position, and the printing head is separated from the label paper and the high-temperature printing roller under the action of the position returning component.

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.

Preferably, the position restoring member is a spring or a spring plate.

The beneficial effects of the utility model are that, the label printer, set up in original printer and print pause time sensing sensor and beat printer head position and reply the component, after printing pause a period, will beat printer head rising playback automatically, break away from and the contact of label paper and print roll, avoid label paper and beat printer head and take place to bond, guarantee that smooth, the going on in succession of printing, 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 diagram of an improved label printer for preventing label sticking 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 present invention provides an improved label printer for preventing label adhesion, which comprises an upper cover 10, a printer main body 30 and a power circuit control module 20, wherein the front of the printer main body 30 is provided with a paper inlet 31, the paper inlet is provided with a paper feeding sensor 34, two sides of the paper inlet are provided with a baffle 36, a printing head 22 is arranged in the printer main body 30, a pressure roller 225 is arranged above the printing head, a printing roller (rubber heating roller) 223 is arranged below the printing head, a first label paper conveying roller set 33 is arranged in front of the printing head 22, and a second label paper conveying roller set 35 is arranged behind the printing head 22; a first sensor 42 is arranged between the printing head 22 and the second roller set 35, and a position restoring member 43 is connected to the printing head 22 and is connected to a fixed structure 41 on the printer main body 30; 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 225 is driven by a driving motor (not shown) to press the printing head downwards and keep the printing head in contact with the printing roller to perform normal printing; after the printing process is stopped, the first sensor 42 senses the time for stopping printing, when the time for stopping printing reaches a preset time value, the driving motor of the pressure roller releases the pressure on the pressure roller, the pressure roller 225 returns, the printing head 22 returns upwards under the action of the position returning component 43 and is separated from the label paper and the high-temperature printing roller, and the label paper is prevented from being adhered to the printing head; when the printer receives the command to recover the printing work, the first roller set and the second roller set rotate, and the pressure roller presses the printing head down under the driving of the driving motor to restart the normal printing work.

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.

In another preferred embodiment, the position restoring member 43 is a spring or a leaf spring.

The utility model discloses a label printer sets up in original printer and prints pause time sensing sensor and beat printer head position and reply the component, after printing pause a period, will beat printer head rising playback automatically, break away from and the contact of label paper and print roller, avoids label paper and beat printer head and take place the bonding, guarantees going on smoothly, continuously of printing, avoids iterative 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.
