Needle printer for multicolor printing

Abstract

The invention discloses a needle printer for multicolor printing. The needle printer for multicolor printing comprises a printer body; the right side of the upper surface of the printer body is fixedly connected with the lower surfaces of two fixed blocks; a rotating mechanism is clamped on the opposite surfaces of the two fixed blocks; the upper surface of the rotating mechanism is fixedly connected with the lower surface of a dustproof cover; the upper surface of the printer body is fixedly connected with the lower surface of a support plate; and the left side surface of the support plate isfixedly connected with the right side surface of a movable plate through a spring. Through a rotating shaft, a bearing, the dustproof cover, a handle, the support plate, the spring, the movable plate, a slide rod, a first slide sleeve, a fixed plate, a second slide sleeve and a through hole, the needle printer for multicolor printing prevents external dust from falling on printing papers in a paper inlet, reduces the influence on the printing effect by the dust falling on the printing papers, achieves convenience on use of the printer by people, and is compact in structure, reasonable in design and high in practicability.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a dot matrix printer for multi-color printing. Background technique [0002] A printer is one of the output devices of a computer, which is used to print computer processing results on related media. There are three indicators to measure the quality of a printer: printing resolution, printing speed and noise. There are many types of printers. According to whether the printing element hits the paper, it can be divided into impact printers and non-impact printers. [0003] The multi-color printers commonly used by people do not have a dust-proof structure. When people use the printer, the paper in the paper inlet is placed for a long time to absorb dust very easily, which affects the printing effect and brings inconvenience to people's use of the printer. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the...
