Paper positioning and driving device for label printer and application method thereof

Abstract

The invention provides a paper positioning and driving device for a label printer and an application method thereof. The structure comprises a mechanical structure and an electrical structure, whereinthe electrical structure is arranged to make contact with and fixed to at least one element of the mechanical structure, the mechanical structure comprises a structural part, an infrared light-emitting tube, a first photosensitive sensor and a second photosensitive sensor, the structural part is used for fixedly installing electronic components of the electrical structure, the electrical structure drives the infrared light-emitting tube to emit light through a generated control signal, and the first photosensitive sensor and the second photosensitive sensor receive infrared light emitted by the infrared light-emitting tube. According to the method, the above-mentioned device is adopted for positioning / driving, the problem that label paper is inaccurate in positioning and poor in compatibility is effectively solved on the premise of low cost, accurate positioning of label consumables and black label consumables can be achieved, and the reliability of products is greatly improved.

Description

technical field [0001] The invention relates to the technical field of label printers, in particular to a paper positioning and driving device of a label printer and a method applied to the device. Background technique [0002] Most of the label printers currently on the market use photoelectric sensors for label paper positioning. [0003] In practical applications, there are differences in the consistency of the photoelectric characteristics of the sensor itself, differences in the accuracy of the drive circuit resistance capacitor, differences in the parasitic impedance characteristics of the conductive line, and difficulty in controlling the tolerance shift in structure preparation and assembly. There are differences in characteristics such as material, light transmittance, etc., and even various factors such as light and temperature in the working environment will affect the accuracy of label positioning. [0004] Therefore, problems such as inaccurate positioning of l...
