Description

Avoid label warping's label printer

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 peeling of labels and release paper due to label warping when the labels are printed.

Background

The label printer is widely used in various occasions such as factories, warehouses, shops, logistics, transportation and the like, and is used for printing labels with various information such as bar codes, prices, places, models and the like. The label is generally a self-adhesive label with back adhesive, before printing, a blank label is adhered to release paper and enters a printer along with the release paper to print contents, and after printing, the label is taken off from the release paper and is directly adhered to an article. Referring to fig. 1, when an existing label printer is used for printing, especially when industrial labels such as logistics and express delivery with large size are printed, blank labels are folded and stacked together, one piece of label paper is uniformly attached to continuous release paper at intervals, when the side of the label paper 1 continuously enters a paper inlet 3 of the printer upwards for content printing, due to the action of self gravity and the control of labels at the rear end, the labels to be printed close to the paper inlet can be bent downwards, the rear end falls, the front end of the labels easily warps, namely, the labels 1 and the release paper 2 are separated, so that the labels cannot smoothly enter the paper inlet 3 of the printer for printing, paper jam is formed, and the discontinuity of the printing process and the waste of the blank labels are caused.

Disclosure of Invention

The warpage that appears when printing to the great label paper of current size leads to the label and from the problem of type paper separation, the utility model aims at providing a can avoid label warping label printer completely, guarantee the continuity of work, avoid the waste of blank label.

In order to realize the purpose of the utility model, the label printer for avoiding label warping comprises an upper cover, a printer host and a circuit control module, wherein the front of the printer host is provided with a paper inlet, a paper feed sensor is arranged on a paper feed plate of the paper inlet, two sides of the printer host are provided with size adjusting baffles for adjusting the width of a printed label, a printing head is arranged at the middle lower part in the printer host, a printing part of the printing head is arranged upwards, and the height in the horizontal direction is positioned below the horizontal height of the paper inlet; the paper feeding plate is arranged behind the printing head, and the horizontal height of the paper feeding plate is equal to the height of the paper feeding plate; label paper conveying roller sets are arranged in front of and behind the printing head; an upper cover release button is arranged on the upper cover.

Preferably, a pressure roller is arranged below the printing head, and the printing head is tightly attached to the printing roller above the pressure roller during printing; when printing is suspended, the pressure of the pressure roller is released, and the printing head is separated from the printing roller.

The beneficial effects of the utility model are that, label printer will beat printer head reverse setting, be located the planar below of label paper feed, when printing, place the label reverse, label paper's one side down promptly, continuous from type paper above, so, at the printing in-process, even blank label takes place more serious bending in transmission process and also can not lead to label paper and from the type paper separation, simultaneously, can also avoid printing and suspend back label paper and beat printer head and take place the problem of gluing the card, guarantee going on smoothly of printing.

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 illustrating a problem of warping of a conventional label paper with a large size during printing;

fig. 2 is a schematic structural diagram of a label printer for preventing label warpage according to an embodiment of the present invention;

fig. 3 is a schematic view of the 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. 2, a schematic structural diagram of a label printer for avoiding label warpage 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 circuit control module 20, a paper inlet 31 is disposed in front of the printer main body 30, a paper feeding sensor 34 is disposed on a paper feeding plate 32 of the paper inlet 31, size adjusting baffles 36 for adjusting the width of a printed label are disposed on both sides of the paper feeding sensor, a printing head 22 is disposed at a middle lower portion inside the printer main body 30, a printing part of the printing head 22 is disposed upward, and a height in a horizontal direction is located below a horizontal height of the paper inlet 31; a paper feeding plate 24 arranged behind the printing head 22, wherein the horizontal height of the paper feeding plate 24 is equal to the height of the paper feeding plate 34; label paper

conveying roller sets

33 and 35 are arranged in front of and behind the printing head 22; 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 will beat printer head reverse setting, when can also avoiding the printer print job to suspend, the label with beat the problem that the printer head bonded. Specifically referring to fig. 3, when the printer normally prints, in order to ensure the printing quality, the print head 22 and the print roller 225 (heating roller) need to be tightly attached together by the pressure roller 223, after the printing operation is terminated, since the label paper is continuously rolled up, and the label paper is still left between the print roller and the heating roller, but the pressure roller is loosened, according to the traditional design mode that the print head is arranged above the printing paper, the print head cannot be completely separated from the print roller due to the self-gravity, the print head still presses on the label paper, and in addition, the temperature of the print roller is still higher, the label paper and the print head are bonded, so that the paper feeding stagnation is generated when the printing is restarted, and the problem of paper jam is generated; when the printing head is reversely arranged, after the printing of the label is stopped, the pressure roller is loosened, and the printing head can be separated from the printing roller after the pressure is released due to the self gravity, so that the label paper can not be adhered to the printing head under the condition of high temperature, and the printing can be smoothly continued to print after the printing operation is restarted.

The utility model discloses a label printer will beat the reverse setting of printer head, is located the planar below of label paper advance, when printing, places the label reverse, and the one side of label paper is down promptly, and continuous from type paper above, so, at the printing in-process, even blank label takes place more serious bending in transmission process and also can not lead to label paper and from the type paper separation, simultaneously, can also avoid printing and stop back label paper and beat printer head and take place the problem of gluing the card, guarantee going on smoothly of printing.

The present invention is not limited to the embodiments described above, and those skilled in the art may 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.
