Problems solved by technology

The gravure printing machine is the only printing machine that can be used for decorative coil printing, but it has the following main defects: 1. The scraper of the gravure printing machine is very prone to knife jumping
Knife jumping is the most troublesome problem in gravure printing. First, it is unpredictable when the knife jumping occurs. Second, once the knife jumping occurs, it will cause defective printing. Third, the frequency of occurrence is relatively high.
2. The scraper device of the gravure printing machine cannot adapt to different diameters of rollers at the same time
In order to fully express the beautiful and real patterns of

Embodiment Construction

[0019] As shown in Figure 1, the scraper device of the gravure printing machine for decorative coils is provided with a synchronous lifting shaft 1 for scrapers positioned on the wallboards on both sides, and a shaft sleeve 3 and 20 on both sides of the shaft is respectively positioned with a rack. Up and down movement column 8, each bushing has a gear positioned on the synchronous lifting shaft of the scraper and meshed with the rack of the up and down movement column; there is a worm gear mechanism driven by a hand wheel to rotate the gear, Figure 4 It can be seen that the worm gear 20-2 is fixed on the scraper synchronous lifting shaft 1, the rotation of the worm 20-1 drives the worm gear 20-2 and the scraper synchronous lifting shaft 1 to rotate, and the synchronous lifting shaft 1 and the gears on both sides of the shaft (the right end is the gear 20- 3, the rotation of the left end gear (omitted in the figure) makes the up and down movement column 8 in the axle sleeves o...

Abstract

The present invention relates to a scraper device of gravure printing machine. Said scraper device comprises the following components: A. in the shaft sleeve of each of two sides of scraper synchro lifting an up-down movement column is positioned respectively; B. on the top end of said movement column a plate-turning shaft sleeve is fixedly mounted, in said shaft sleeve a turnable scraper plate-turning shaft is positioned; and C. on the scraper plate-turning shaft a scraper carrier device also is positioned, and said device also is equipped with a scraper-skipping prevention mechanism. Said invention also provides the concrete structure of said scraper-skipping prevention mechanism.

Description

technical field [0001] The invention relates to a key device of a gravure printing machine used for printing decorative coils, in particular to a scraper device of the gravure printing machine. Background technique [0002] my country is a populous country, but forest resources are extremely poor, so the use of paper instead of wood has been widely used in urban and rural areas of our country for more than ten years. The so-called paper instead of wood is to use paper (also PVC, aluminum foil and other coils) to print on the surface, so that the surface has wood grain or stone grain, cartoon grain, etc., and then used as the surface finish of wood-based panels, widely used It is applied in the decoration industry, furniture industry, office supplies, laminate flooring and other fields to meet people's needs for beautifying life and improving quality of life. The gravure printing machine is the only printing machine that can be used for decorative coil printing, but it has t...
