Air curtain cleaning mechanism for printing equipment

Abstract

The invention discloses an air curtain cleaning mechanism for printing equipment, which comprises: a support mechanism fixedly installed above the intermediate finished printed matter; Blow and brush the intermediate finished product of the printed matter below intermittently. The supporting mechanism includes a first bracket and a second bracket respectively installed on both sides of the intermediate finished product of the printed matter. The blowing device includes a hollow rotating cylinder, which has a degree of freedom of rotation around the axis of the cylinder relative to the supporting mechanism. The middle part of the rotating cylinder is an air-collecting chamber, and the blowing and brushing air curtain device is installed on the rotating cylinder. A plurality of epitaxial plates extending in the normal direction on the outer peripheral wall, each of which has a hollow epitaxial channel, the gas collection chamber communicates with an external air source, and an outer end of each of the epitaxial plates extends along the axis of the drum. the air outlet seam. The invention is used for cleaning the solid residue on the surface of the printed matter and improving the output quality of the intermediate finished product of the printed matter.

Description

technical field [0001] The invention relates to the field of processing technology for intermediate products in the anti-counterfeiting printing industry, in particular to an air curtain cleaning mechanism for printing equipment. Background technique [0002] Generally, for certificates, lottery tickets, exchange coupons and other printed matters, anti-counterfeit printing processes are required, for example, hot stamping LOGO or hollowed-out patterns need to be printed. These processes will inevitably lead to some solid residues on the surface of the printed matter, such as some waste residues, residues, particles after solidification of ink droplets, etc. If this solid residue is not removed in time, it will affect the printed matter. Or when cutting and stacking, it will cause adverse effects on quality. Today's printing companies lack the treatment methods for removing solid residues, or most of them add unpowered horizontal brushes to clean the equipment's output positi...

Problems solved by technology

These processes will inevitably lead to some solid residues on the surface of the printed matter, such as some waste residues, residues, particles after solidification of ink droplets, etc. If this solid residue is not removed in time, it will affect the printed matter after it is discharged. Or when cutting and stacking, it will cause adverse effects on quality. Today's printing companies lack the treatment methods for removing solid residues, or most of them add unpowered horizontal brushes at the output position of the equipment to clean, although it can play a role. Sweeping effect, but may cause damage to the surface of the printed matter due to excessive or uneven dragging force of the brush
