This scraper mechanism passes through worm gear and worm and rack and pinion mechanism and bearing roll removal, has realized that single light adjustment scrapes knife rest position, has improved work efficiency and printing quality, stabilizes the three tandem axle of triangle-shaped arrangement simultaneously, has avoided the scraper to cause the unbalanced phenomenon of moment around the during operation.
Description
Technical Field
The utility model relates to an intaglio printing machine, more specifically say so and relate to a portable scraper mechanism on intaglio printing machine.
Background
The scraper on the gravure press is used for scraping off the unnecessary printing ink that adheres to on the material membrane for the printing ink overburden is even, and the scraper is fixed and is relied on the cluster movable shaft at scraper frame both ends to move on the cluster movable shaft support about on scraping the scraper frame, and current scraper frame is through two upper and lower cluster movable shafts at both ends about moving, and such scraper is moment unbalance around the during operation, causes the scraper to leak during the printing and scrapes the phenomenon, thereby causes the colour of printing pattern to be different. Moreover, all be through two people concurrent operation when adjusting the scraper position at every turn, perhaps artifical hand push scraper frame both ends are adjusted in proper order, can not do both ends synchronous adjustment, and the position of adjustment is only several fixed points moreover, can't accurately transfer to ideal position, must assist other adjusting device of adjustment to accomplish, and the adjustment process is loaded down with trivial details, and is inefficient.
Disclosure of Invention
In order to solve the problem existing in the technology, the utility model provides a portable scraper mechanism on gravure press.
The utility model discloses a realize through following technical scheme: the utility model provides a portable scraper mechanism on gravure press, includes scrapes the knife rest, scrapes the string moving shaft on the string moving shaft support of passing through on the both ends of knife rest, be provided with three string moving shaft on the scraper support, two below the above-mentioned one of three string moving shaft are stable triangular distribution, scrape and be provided with the slide between knife rest and the scraper support, the slide passes through the bearing and installs in the scraper support and can slide in the scraper support, and the lower extreme of slide is provided with the rack, the below of scraping the knife rest is provided with the adjustment axle, the both ends of adjustment axle be provided with respectively with rack engaged with gear, the centre of adjustment axle is provided with the worm wheel, and the below of worm wheel is provided with complex worm with it, is provided with the hand wheel on the.
In the above scheme, in order to accurately and intuitively see the moving position of the sliding seat, the worm is provided with the scale.
In the scheme, the upper side surface and the lower side surface of the sliding seat are respectively provided with a bearing, and the sliding seat is supported in the sliding groove of the scraper support by the bearings.
The utility model relates to a portable scraper mechanism on gravure press compares with prior art, and its beneficial effect is:
1. the scraper mechanism is provided with three tandem shafts and is in a stable triangular arrangement, so that the phenomenon that the front and rear moments of the scraper are unbalanced when the scraper works is avoided.
2. The scraper mechanism realizes that a single person can easily adjust the position of the scraper frame through the rolling movement of the worm gear, the gear rack mechanism and the bearing, and improves the working efficiency and the printing quality.
Drawings
Fig. 1 is a schematic structural diagram of a movable scraper mechanism on an intaglio printing press according to the present invention.
Fig. 2 is a sectional view a-a of fig. 1.
Fig. 3 is a sectional view B-B of fig. 1.
In the figure: 1. the scraper comprises a serial shaft support, a serial shaft 2, a scraper support 3, a bearing 4, a sliding seat 5, a scraper frame 6, a rack 7, a gear 8, an adjusting shaft 9, a worm wheel 10, a worm 11, a worm 12 and a hand wheel.
Detailed Description
The following describes a movable doctor mechanism of an intaglio printing press with reference to the accompanying drawings:
figure 1 is a schematic structural view of a movable doctor mechanism on an intaglio printing machine according to the present invention,
fig. 2 is a sectional view a-a of fig. 1, and fig. 3 is a sectional view B-B of fig. 1. In the figure, the movable scraper mechanism on the gravure press comprises a scraper frame 6, two ends of the scraper frame 6 are serially moved on a string-moving shaft support 1 left and right through three serial-moving shafts 2 on a scraper support 3, the string-moving shaft support 1 is fixed on wall plates on two sides of the press, two lower parts of the three serial-moving shafts on the scraper support 3 are in stable triangular distribution so as to ensure that the scraper frame 6 can always keep the balance of the moment borne by a scraper in the effective moving range of the scraper frame 6, a sliding seat 5 is arranged between the scraper frame 6 and the scraper support 3, the sliding seat 5 is arranged in a sliding groove of the scraper support 3 through upper and lower four bearings 4 and can slide in the scraper support, a rack 7 is arranged at the lower end of the sliding seat 5, an adjusting shaft 9 is arranged below the scraper frame 6, gears 8 meshed with the rack 7 are respectively arranged at two ends of the adjusting shaft 9, a, a worm 11 matched with the worm wheel 10 is arranged below the worm wheel 10, and a hand wheel 12 is arranged on the worm 11. In order to accurately and visually see the moving position of the sliding seat, a scale is arranged on the worm.
When using this mechanism to need the adjustment scraper position, need not two people concurrent operation, also need not alone to control adjustment knife rest position, only need rotate hand wheel 12, drive adjusting shaft 9 through worm gear mechanism and rotate, the steady removal around the rethread gear rack mechanism at both ends drives slide 5 and scraper frame 6 in scraper support 3 to the accuracy reaches the suitable clearance between scraper and the printing material membrane, thereby has realized that the scraper can stop the purpose in optional position.
This scraper mechanism passes through worm gear and worm and rack and pinion mechanism and bearing roll removal, has realized that single light adjustment scrapes knife rest position, has improved work efficiency and printing quality, stabilizes the three tandem axle of triangle-shaped arrangement simultaneously, has avoided the scraper to cause the unbalanced phenomenon of moment around the during operation.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed with reference to the preferred embodiment, it is not limited to the present invention, and any skilled person in the art can make various changes or modifications equivalent to the above embodiments without departing from the scope of the present invention, but all the modifications, changes and modifications of the above embodiments by the technical spirit of the present invention are within the scope of the present invention.
