Printer auxiliary framework for preventing paper deflection through air pressure adsorption

Abstract

The invention relates to the technical field of office equipment, and provides a printer auxiliary framework for preventing paper deflection through air pressure adsorption. The printer auxiliary framework comprises a support, a guide wheel is movably connected in the support, a roller shaft is movably connected to one side, away from the support, of the guide wheel, a gravity block is movably connected in the roller shaft, and the surface of the gravity block is movably connected with a spring rod. According to the printer auxiliary framework for preventing paper deflection through air pressure adsorption, suction force is needed for suction when paper moves to the lower half side of the roller shaft, when the gravity block moves to the upper half side of the roller shaft, the gravity block is initially clamped by the clamping block, when the gravity block is about to reach the top end, the gravity block is separated from control of the clamping block, the gravity block compresses the spring rod to move, the gravity block and a curved bar are matched to enable a push-pull plate to move, the push-pull plate extrudes an air bag layer to spray air to prevent paper from winding the roll shaft, the roll shaft is bilaterally symmetrical, airflow convection controls the paper not to deflect, and the air suction and blowing states of the upper side and the lower side are controlled to prevent the paper from being bent.

Description

technical field [0001] The invention relates to the technical field of office equipment, in particular to an auxiliary structure of a printer that uses air pressure adsorption to prevent paper deflection. Background technique [0002] In the daily office of an enterprise, there are often a large number of documents that need to be approved, and complex work needs to be communicated and arranged. Smart office equipment is necessary. Smart office equipment can realize resource sharing and rapid communication. Printers are an intelligent Office equipment, printers can print computer processing results on related media. Printers have the characteristics of small size, low cost and fast printing speed. Printers reduce printing steps to play the role of energy saving and environmental protection. Printers are convenient for data recording and dissemination.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, since the printer uses the roller shaft to drive the paper, the roller shaft guides the paper, but due to the gravity of the paper itself and the degree of tortuousness, the paper will fall off the roller shaft, resulting in waste of paper, which is not energy-saving and environmentally friendly. It cannot work normally, and some paper dust will be adsorbed on the roller shaft. The paper dust will affect the gap between the roller shaft and the paper, and the paper dust will continue to accumulate and jam the roller shaft. Therefore, a printer that uses air pressure adsorption to prevent paper deflection Auxiliary architecture emerges
