Colored tape printing head for industrial recorder

Abstract

The invention discloses a colored tape printing head for an industrial recorder. The colored tape printing head comprises a housing, wherein an electromagnet assembly and a magnet attraction pressuresheet which is matched with the electromagnet assembly are mounted in the housing; one end of the magnet attraction pressure sheet is connected to a printing needle which is mounted on the bottom of the housing in a penetrating mode, and can move up and down; the electromagnet assembly is electrically connected to CPU drive plate; a CPU and a printing signal amplifying drive module are arranged onthe CPU drive plate; through the CPU, an input signal drives the colored tape printing head to perform real-time printing on a colored tape through a printing signal amplifying drive module, and thecolored tape is directly driven by a pulse signal output by the CPU, so that a colored curve is formed on recording paper, and therefore, effective real-time recording, on an external measuring signal, of the recorder is realized. The colored tape printing head is convenient in assembly, is low in manufacturing cost, is high in reliability, is long in service life, is strong in anti-interference ability, realizes quick measuring and recording of the recorder, and also guarantees a long service life and low manufacturing cost of the printing head.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a ribbon printing head for industrial recorders. Background technique [0002] The print head is the key component of the industrial automatic balance dotted paper recorder. Its main function is to amplify small measured signals such as thermocouples, thermal resistances, and millivolts through CPU operations to drive the print head to print the ribbon and form a record on the recording paper. Curves to realize the actual measurement records of physical quantities controlled by industrial automation sites. [0003] At present, the printing head used in our country is a purely mechanically rotating multi-point printing head, which can print recording curves of 12 colors. However, the purely mechanical print head needs to be driven by multi-stage synchronous motors, which is not efficient; and there are many parts, which require extremely high machining accuracy and high manufact...

AI Technical Summary

Problems solved by technology

However, the purely mechanical print head needs to be driven by multi-stage synchronous motors, which is not efficient; and there are many parts, which require extremely high machining accuracy and high manufacturing costs; the color wheel is inconvenient to install, and the color cotton corresponding to the color wheel must be separated. Note 12 different inks; easy to get stuck without dots and ink leakage
