Print fluting machine with double-mode ink uniformizing device at printing part

Abstract

The invention discloses a print fluting machine with a double-mode ink uniformizing device at a printing part. The print fluting machine comprises a squeegee mechanism and a doctor blade squeegee mechanism, wherein the squeegee mechanism consists of a rubber roller and an anilox roller; and the doctor blade squeegee mechanism is arranged laterally below the rubber roller and the anilox roller. The print fluting machine is characterized in that the rubber roller is tightly pressed against the anilox roller to primarily squeegee the anilox roller; a doctor blade is also tightly pressed against the anilox roller under the action of a cylinder to secondarily squeegee the anilox roller; the primary squeegee ensures large-area inking of the anilox roller; the secondary squeegee can keep that the ink on the anilox roller is thin and uniform and does not block screen dots; because the doctor blade squeegee is to uniformize the ink twice based on the squeegee of the rubber roller, the print fluting machine solves both the problems of non-uniform inking on the anilox roller caused by the primary squeegee of the rubber roller and improper printing of a big solid place due to the thin inking layer; and the rubber roller squeegee and the doctor blade squeegee can be individually used or combined to achieve high economy and effectiveness in consideration of the requirements of the presswork.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a printing and slotting machine which is fed by a paper guide wheel, and its printing part is provided with a double-mode ink distribution device. Background technique [0002] Printing slotting machine is a widely used packaging machinery, its main structure is as follows figure 1 As shown, it includes a paper feeding unit 11, a plurality of printing units 13, a slotting unit 14 and a die-cutting unit 15. Each unit works in a unified and coordinated manner under the action of the power equipment and the transmission mechanism, and jointly completes the paper feeding, printing, and printing of the cardboard. Grooving and die cutting. The printing part is equipped with a dual-mode ink distribution device, which uses two independent scraping mechanisms, one mechanism is composed of a rubber roller and an anilox roller, through the opposite operation of the two, the ink is stored in the Betw...

Problems solved by technology

[0003] With the advancement of technology, the productivity of printing, slotting and die-cutting of the printing slotting machine is getting higher and higher, and it is now developing at a speed of 60 sheets per minute to 250 sheets per minute. This increase in productivity is bound to bring It is required to speed up the frequency of paper feeding and higher printing accuracy. To achieve printing on coated paper up to 60-70L / inch, while the traditional printing slotting machine with paper feeding by guide rollers, with the increase of printing speed It will produce different changes in color depth, the higher the speed, the greater the amount of ink, the more severe the dot blocking phenomenon, and the worse the printing effect, which seriously affects the quality of carton printed matter and hinders the printing and slotting machine of the traditional paper feeding method. In order to speed up the printing speed and improve the printing quality, it is necessary to spend an expensive price to purchase a high-end printing slotting machine, which adds a great burden to a large number of small and medium-sized carton companies and causes serious losses. production

Therefore, there is a need for a printing and slotting machine that can print ordinary cardboard boxes on the traditional printing and slotting machine that is fed by a paper guide wheel, and can also print high-quality products under the premise of increasing production speed, so as to meet the development needs of different carton companies. needs, the existing technical methods are no longer suitable for the requirements of the market, and users have strongly responded
