Description

Guiding mechanism of printer label paper

Technical Field

The utility model relates to a printer, in particular to a guide mechanism of label paper of the printer.

Background

The existing label paper guiding mechanism of the printer peels off labels through a simple sharp-corner peeling block, and the labels can only be peeled off along the length direction of the printer. The paper loading track of the label paper is limited by two paper guide shafts, so that the label paper can correctly pass through the paper shortage sensor; however, this method has a possibility of various paper passing paths, and the operator is easily mistaken. As shown in fig. 1-2, the printer peels off the label along the horizontal length of the printer, and the application of such a printer in a labeling device results in a larger profile of the device due to the larger dimension in the length direction; the printer can be normally used only by loading paper according to a specified track, and various paper-penetrating possibilities exist in the printer, so that the printer has no fool-proof function, and an operator is unskilled and is easy to install wrongly; the label scroll that this printer used, scroll outside diameter is big, and inboard diameter is little, and certain crooked radian can be produced during peeling off owing to keep crooked for a long time to the label paper, and outside diameter is great with inboard diameter difference, and when leading to the label to peel off, the terminal position change of label is great, can image and printer complex labeller, causes to paste the mark badly.

the printer hanging plate 3 is arranged at one end above the label printer core 1, the center of the printer hanging plate 3 is provided with a front correction shaft 6, and both sides of the front correction shaft 6 are provided with back correction shafts 5; the main printing paper shaft 4 is arranged at one end of the printer hanging plate 3, and the main printing paper shaft clamping ring 8 is arranged on the main printing paper shaft 4; a mounting column is arranged on one side of the other end of the label printer core 1, and a thermal head mounting plate 11 is arranged on the mounting column; the other end of the thermal head mounting plate 11 is provided with a paper rolling mechanism 14, and the thermal printing head 12 is arranged on the thermal head mounting plate 11; a hinged column is installed on one side of the installation column, the first paper guide support 15 is hinged to the hinged column, the second paper guide support 17 is installed at the other end of the first paper guide support 15, and the second paper guide support 17 is connected with a stripping block 18.

In this embodiment, the U-shaped photoelectric switch 2 is installed below the printer hanging plate 3, and the photoelectric sensor 10 is installed on one side of the thermal head mounting plate 11.

In this embodiment, a correction flap 7 is attached above the back correction shaft 5.

In this embodiment, the movement original 16 is installed above the peeling block 18, and the peeling block 18 is connected to the paper rolling mechanism 14 through the movement original 16.

In this embodiment, the shaft fixing ring 9 is installed above the main printing paper shaft retaining ring 8, and the shaft fixing ring 9 is fixed on the main printing paper shaft 4.

The working principle is as follows:

through setting up the aligning gear that 3 guiding axles are constituteed, make printing paper go on reverse crooked correction before getting into to beat printer head. The front correcting shaft is in contact with one surface of the label paper, the back correcting shaft is in contact with one surface of the base paper, and the printing paper is bent and corrected by taking the one surface of the label paper as the inner side, so that bending caused by rolling up of the paper roll is offset, and partial internal stress is eliminated. The radian that every label paper carries out crooked correction is unanimous, makes the uniformity of label paper improve, has avoided the inconsistent problem of the crooked radian of label paper that leads to of scroll inside and outside diameter. The label paper is positioned on the inner side of the bend correction, and cannot be peeled off during correction.

The printing paper passes through the position of the paper-out detection sensor after being reversely bent and corrected. The paper shortage detection sensor is of a U-groove-shaped structure, and the label paper can be identified only by being correctly positioned in the U groove. The sensor is surrounded and guided by adding two guide plates (a paper guide bracket and a paper guide bracket II) at the position, so that the printing paper can be more easily loaded to the detection position when being loaded. By designing the special shapes of the two guide plates, the guide shafts, the rotating shafts and the like on the printer are covered and shielded, so that the path of the printing paper from the correcting shaft, the printing head and the paper returning shaft is unique, and the printing paper cannot be placed to the bottom by an incorrect path.

The printing paper passes through the paper shortage detection sensor and then enters the printing head, and then is pressed by the paper rolling mechanism and then winds the peeling sharp corner. And bending the printing paper by using a roller on the paper rolling mechanism, and controlling the label paper to turn 90 degrees by matching with the peeling sharp angle to peel. And the relative position of the roller mechanism and the peeling sharp corner is changed, so that the peeling direction of the label can be adjusted at will (within 90 degrees).

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
