A paper clamping device for a printing machine

Abstract

The invention discloses a paper clamping device for a printing machine. The paper clamping device comprises a printing machine body and a stacking table located on one side of the printing machine body, and one end of the printing machine body is connected with dust collection flattening parts; the interior of the stacking table is connected with paper clamping parts, and one ends of the dust collection flattening parts are in contact with the paper clamping parts; the output ends of the paper clamping parts are connected with a microcomputer controller electrically, and the end, far away fromthe dust collection flattening parts, of each paper clamping part is connected with a trimming part; and the trimming part is connected with the interior of the stacking table. According to the paperclamping device, added carton pieces enter at the same angle through the arranged trimming part, and offset of the printing position of a plurality of carton pieces due to different stacking angles is avoided; meanwhile, the surfaces of the stacked carton pieces are extruded through the arranged paper clamping parts; after the carton pieces enters the dust collection flattening parts, since the carton pieces are in contact with arranged adsorption flannelette, dust is removed through the adsorption flannelette; and meanwhile, the paper clamping device benefits leveling of imprints and maintaining of the printing quality.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a paper clamping device for printing machines. Background technique [0002] A machine for printing text and images. Modern printing machines are generally composed of plate loading, ink application, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink to the place where the text and image are on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Print onto paper or other substrates such as textiles, sheet metal, plastic, leather, wood, glass, and ceramics to reproduce the same print as the printing plate. The invention and development of printing presses play an important role in the spread of human civilization and culture. For printing machines used for ...

Problems solved by technology

[0003] The traditional carton printing machine squeezes the paper on the carton through the roller and the belt. After the carton is squeezed by the roller, there will be marks on the surface. At the same time, when the carton is piled up in the warehouse, there will be paper scraps or other dust on the surface. If the surface Imprints and sundries are not removed in time, and the printing paint and imprints or sundries are adsorbed during printing, resulting in poor printing quality. At the same time, cartons are added before the cartons are used up, and the edges of the cartons are not even when they are stacked. The printing position will be relatively offset during printing, so we propose a paper clamping device for printing machines
