Embodiment Construction

[0029] The present invention will be described in further detail below by means of specific embodiments:

[0030] The reference signs in the drawings of the specification include: chassis 1, carton 2, paper outlet 3, upper cover 4, lower cover 5, shielding frame 6, connecting rod 7, sliding seat 8, sliding table 9, limit block 10 , rotating shaft 11, paper roller 12, compression spring 13, guide post 14, torsion spring 15, screw mandrel seat 16.

[0031] as attached figure 1 As shown, the existing large printers generally include a carton 2 for placing paper, and the carton 2 is slidingly connected to the cabinet 1 in a drawer type. The case 1 includes an upper cover 4 and a lower cover 5 in a rectangular structure. The paper outlet 3 is located above the upper cover 4 . A paper roller 12 for feeding the paper in the paper tray 2 into the printing assembly is installed in the cabinet 1 . The upper cover 4 and the lower cover 5 respectively include first and second left pla...

Abstract

The invention discloses a dampproof method for a black and white printer. The dampproof method comprises the following steps that firstly, the black and white printer is started, a work loop is electrified, an electromagnet communicating with the work loop is conducted, and magnetism the same with the magnetism of a magnet sheet is generated; secondly, magnetism repelling is generated through theelectromagnet, and the magnet sheet and a shielding frame provided with the magnet sheet are pushed to move upwards; thirdly, the shielding frame drives a connecting rod and a sliding base connected with the connecting rod to move in the direction away from the rotation shaft; fourthly, the rotation shaft on a paper roller loses limitation from the sliding base, the paper roller rotates for papertaking according to a printing command of the black and white printer, and the black and white printer finishes printing; fifthly, the black and white printer is stopped, the work loop is powered off,and the electromagnet communicating with the work loop is in an outage state, and magnetism is lost; and sixthly, the shielding frame downwards slides to the bottom of a sliding way along the slidingway, and the shielding frame shields a gap between an upper cover and a paper box.

Description

technical field [0001] The invention relates to the field of printers, in particular to a moisture-proof method for black and white printers. Background technique [0002] Printers are office equipment that we often use in our daily work. [0003] as attached figure 1 As shown, the existing large-scale printers generally include a carton for placing paper, and the carton drawer is slidingly connected to the casing, and the casing is provided with a paper roller that is used to feed the paper in the carton into the printing assembly; because the paper There is a large gap between the box and the chassis, which will cause water vapor and dust in the air to enter the carton through these gaps and adhere to the paper, which not only makes the paper in the carton very susceptible to moisture, but also makes the paper And affect the printing component to print text and patterns on paper, affecting the printing effect. In addition, during the printing process, if there is a sudd...
