Description

Technical Field

[0001] The invention belongs to the technical field of printer cores, and in particular relates to a label printer core. Background Art

[0002] Printer is one of the output devices of a computer, used to print the results of computer processing on relevant media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise.

[0003] There are many types of printers;

[0004] A label printer or smart label printer does not need to be connected to a computer. The printer itself has an input keyboard or smart touch screen, and has certain fonts, character libraries and a considerable number of label template formats built in. Through the LCD screen on the body, you can directly input, edit, and layout the label content according to your needs, and then directly print out the output.

[0005] Label printers are indispensable in daily work, and the printer movement and gap sensor components usually adopt an integrated design. This design makes the gap of the gap sensor unable to be adjusted, and thus cannot adapt to papers of different thicknesses and types. When printing papers of different thicknesses, it is often necessary to replace print heads of different specifications or adjust the overall parameters of the printer, which will affect the printing quality and efficiency. At the same time, the used carbon ribbon has strong static electricity, and the winding roller of the label printer is usually made of plastic. The static electricity on the carbon ribbon wrapped around the outside of the winding roller is difficult to release, and static electricity will affect the printing quality of the print head and the service life of the printer.

The moving speed and position of the print head. When the print head moves on the paper, the gap sensor 1104 and the gap sensor 2 1106 will continuously detect the edge of the paper, and adjust the speed and position of the print head according to the detected signal to ensure that the printed label gap is accurate, thereby improving the printing quality and efficiency of the device. Since the detection plate 1101 and the inclined slope 1103 form a "J"-shaped structure, the inclined slope 1103 can be tightly fitted with the carbon ribbon, and can be directly closed when the upper cover 3 is manually reset to automatically reset. At the same time, the installation of the carbon ribbon will not be affected when the upper cover 3 is opened and closed. Since the gap sensor 1104 and the gap sensor 2 1106 are installed in groups, they can be quickly replaced, which can prevent the label paper from sticking to the two sides of the gap sensor 1104 and the gap sensor 2 1106. Since the gap sensor 1104 and the gap sensor 2 1106 are arranged in a split type, it is convenient for subsequent paper threading and subsequent cleaning;

[0061] The left and right sides of the upper end surface of the detection plate 1101 are rotatably connected with an extrusion shaft 1102, and the extrusion shaft 1102 has a built-in torsion spring and is connected to the upper cover body 3. The gap sensor 1104 and the gap sensor 2 1106 are provided with fixing bolts 1105 inside, and are respectively connected to the upper cover body 3 and the base body 1. The angle of the detection plate 1101 can be adjusted by the set extrusion shaft 1102, so that the detection plate 1101 can fit tightly with the paper, which can ensure the subsequent detection effect of the gap sensor 1104 and the gap sensor 2 1106, and the set fixing bolts 1105 can quickly install and disassemble the gap sensor 1104 and the gap sensor 2 1106, so as to facilitate subsequent maintenance by the staff. At the same time, the left and right sides of the base body 1 and the upper cover body 3 are all perfectly covered with cover plates to ensure beauty and service life, and there are holes for easy removal to avoid damage during disassembly.

[0062] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
