Multi-purpose seal type print head

Abstract

The invention relates to the technical field of a print head, and discloses a multi-purpose seal needle type print head. The multi-purpose seal needle type print head comprises a machine body and a plurality of print head parts, wherein the print head parts are arranged at the lower end part of the machine body side by side, and a needle ejecting plate is arranged at the lower end part of each print head part. A plurality of print needles are arranged in each print head part, and the upper end of each print needle extends into the machine body. A driving structure used for driving the print needles to move up and down is arranged in the machine body, the upper end of each print needle is connected with the driving structure, and the lower end of each print needle movably penetrates in eachneedle ejecting plate. A gap is formed between the print needles of the adjacent print head parts. A plurality of print head bodies are arranged at the lower end part of the machine body side by side, and a gap is formed between the adjacent print head bodies. The same one print head body realizes multicolor printing on a color zone, and monochrome printing can be realized through multiple printhead parts. The multi-purpose seal needle type print head realizes a one-body multi-purpose effect, does not need to add an inner structure, solves the problems of complex structure and large size, and meanwhile is compatible with most needle printers on the market today.

Description

technical field [0001] The invention relates to the technical field of print heads, in particular to an integrated multi-purpose stamp type print head. Background technique [0002] Dot matrix printer is a kind of commonly used printer. It uses mechanical and circuit drive to make printing needle 14 collide with ribbon and printing paper, print out dot matrix on the paper, and then form characters or graphics by dot matrix to complete the printing task; Dot matrix printers can easily print text, tables and graphics of general quality on printing paper, copy paper, wax paper and envelopes, and also have the characteristics of simple operation and low consumables, especially its unique multi-page copy and carbon copy printing And continuous printing function, so it can print all kinds of professional and strong reports, passbooks, invoices, cards and other output media, which is widely used. [0003] At present, the color of the text or graphics printed by the dot matrix prin...
