A printing roller that eliminates paper dust and powder by periodic vibration of the fuselage

Abstract

The invention relates to the technical field of printing and discloses a printing roller eliminating paper scraps and powder through machine body periodic vibration. The printing roller comprises a barrel. The two sides of the barrel are each movably connected with a rotary shaft. An ink pipe is fixedly connected to the bottom wall in the barrel. A driving mechanism is fixedly connected to the upper portion of the ink pipe. A mutual communicating mechanism is fixedly connected to the lower portion of the ink pipe. The driving mechanism comprises a shell. A hollow channel is fixedly connected in the shell. A rotary hole is movably connected in the hollow channel. A gas supply channel is fixedly connected to the position, located above the hollow channel, in the shell. Fan blades are movably connected in the gas supply channel, broken paper and the paper scraps are sucked into a storage groove from an impurity sucking channel, thus the effects that mist ink is cleaned away while the paper scraps are eliminated are achieved, sucking force of an impurity removing channel and a mist sucking channel can be controlled by adjusting the rotary hole, and the phenomenon that ink slides on the surface of paper due to too large sucking force is avoided.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a printing roller for eliminating paper scraps and powders by utilizing periodic vibration of a fuselage. Background technique [0002] After the web of traditional rotary printing machine enters the processing department through the paper guide roller, it passes through the action of the punch roller and the mother roller to punch holes, and the action of the jackknife roller and the jackknife bottom roller to make a dotted line, and then enters the delivery The paper is collected manually. However, due to the long-term use of punches and punches, there will be certain wear and tear, resulting in impermeable punching and paper dust remaining in the semi-finished product. Another reason for paper dust entering the printing machine is: in the initial stage of papermaking , It is more common for paper fragments to appear when the paper is decapitated. These scraps of paper shoul...

Problems solved by technology

If there are pieces of shredded paper caught in the paper, it will cause missing printing and faults during printing. As a result, factories often don’t pay much attention to the problem of one or two pieces of shredded paper caught in the paper, thinking that there is no major impact. In fact, shredded paper The film will bring a lot of trouble and great economic loss to the printing

[0003] When printing on roll paper or flat paper, if there are scraps of paper in them, these scraps of paper will adhere to the paper surface and enter the printing machine. The printing pressure and the viscosity of the ink will make the scraps of paper stick to the rubber cylinder. Or on the layout, so that the text and images here on the printing plate cannot be transferred to the paper, causing the printed matter to form a missing print. On a high-speed printing machine, once this happens, it will make dozens or even hundreds of pages. A piece of printed matter becomes a waste product, and it needs to be shut down to peel off the shredded paper from the rubber roller or the plate. In addition, during the printing process, after the ink and the paper, part of the ink spreads in the form of mist, due to the particularity of the ink. , if it is not treated in time, it will cause certain harm to people after being inhaled into the human body. Therefore, a printing roller that uses the periodic vibration of the fuselage to eliminate paper dust and powder came into being
