Problems solved by technology

There is a problem with this dust removal device, that is, the contact surface between the paper and the rubber roller is small, and the friction force is too small, so it is often impossible to drive the rubber roller to rotate.
This leads to poor dust removal effect, and the paper after dust removal by the rubber roller will generate static electricity due to friction, which will affect the quality of the subsequent printing process

Abstract

The invention discloses a printer feeding device. The printer feeding device comprises a door-shaped frame, wherein an upper dust-sticking roller and a lower dust-sticking roller are arranged in the door-shaped frame, the axes of the upper and the lower dust-sticking rollers are distributed on two parallel vertical planes; a static-removing roller is further arranged in the door-shaped frame; thestatic-removing roller is parallel to the axis of the lower dust-sticking roller; and the upper dust-sticking roller, the lower dust-sticking roller and the static-removing roller all can rotate around the axes. In the invention, the dust-sticking rollers can quickly remove fine particles, impurities, dusts and the like on the surface of paper; the static-removing roller can effectively eliminatethe static generated during the dust removing process of the paper, and cooperates with the lower dust-sticking roller to play a role of stretching, so that paper does not cockle after the dust removal; the finished product ratio of printing products is improved; downtime for cleaning equipment is shortened; defective percentage and paper waste are reduced; the structure is simple; and the deviceis convenient to use.

Description

technical field [0001] The invention relates to the field of printing machinery, in particular to a feeding device of a printing machine. Background technique [0002] The printing machine is an important printing equipment. The creases of the paper when feeding, the dust and impurities attached to the surface of the paper will affect the printing quality of the final product, and the product will be scrapped in severe cases. In the printing process, in order to improve the printing quality, it is usually necessary to dedust the printed paper before printing. At present, a dust removal device that is often used is composed of a door-shaped frame. In the door-shaped frame, an upper dust-sticking roller, an upper rubber roller, a lower rubber roller and a lower dust-sticking roller are sequentially arranged from top to bottom. The axes among the upper dust-sticking roller, the upper rubber roller, the lower rubber roller and the lower dust-sticking roller are parallel to each...
