Description

TECHNICAL FIELD

[0001] The utility model relates to static elimination device technical field, concretely is the surface static elimination device of printed paper. BACKGROUND

[0002] The printing machine is a kind of equipment that is used to press the inked surface on paper, and is widely used in the production field of various books, newspapers, packaging materials and the like.The printing machine is usually composed of plate mounting, ink coating, pressing and paper feeding mechanisms, wherein the paper feeding device is an important component to ensure the continuity of the printing process.The paper feeding device continuously feeds the outer paper of the paper roll to the printing table through the conveying roller, and then cuts the paper after printing.However, during long-term use, due to the continuous contact between the conveying roller and the surface of the paper, the friction will cause the static electricity to accumulate on the surface of the paper.These static electricity may cause a series of problems, such as paper dust adsorption, uneven distribution of printing color, page sticking, and even paper jamming of the equipment, which seriously affects the stability of the printing process and the product quality.In addition, the existence of static electricity may affect the precision sensors and electronic components in some printing equipment, further increasing the production risk.

[0003] The patent with publication number CN213694257U discloses a static elimination device for printing machine paper feeding, which comprises a bearing seat, the bearing seat has two and is symmetrically distributed with the width center line of the printing table, a lifting assembly is arranged between the two bearing seats, a bearing plate is connected to the lifting end of the lifting assembly, a fixed tube is connected to the upper surface of the bearing plate, a filter plate is connected to the upper end of the fixed tube, a blowing fan and a high-voltage generator are installed in the fixed tube, a shunt pipe is connected to the bottom surface of the bearing plate, the shunt pipe is in communication with the fixed tube, the shunt pipe extends along the width direction of the printing table, and an air outlet groove is arranged through the bottom surface of the shunt pipe and extends along the axial direction of the shunt pipe.The beneficial effect is that the blowing fan and the high-voltage generator form a charge flow, the charge flow is blown to the surface of the paper through the air outlet groove, the charge of the paper is combined, the effect of eliminating static electricity is achieved, the dust adhered to the surface of the paper under the action of static electricity is prevented, and the printing quality is ensured.

[0004] The above-mentioned prior art adjusts the distance between the shunt pipe and the printing table by lifting the bearing plate through the lifting assembly to ensure the static elimination effect.However, since the lifting assembly needs to operate two adjusting bolts at the same time to accurately adjust the height of the bearing plate, the operation process is complicated and the efficiency is low.Secondly, the air flow formed by the blowing fan when working may cause the paper to slightly deviate when blowing to the surface of the paper, especially for the relatively thin paper, which may further affect the printing precision, therefore, we propose the surface static elimination device for printed paper.
