Abstract
The utility model discloses a doctor blade lifting mechanism. The doctor blade lifting mechanism comprises a worm wheel (1) and a worm (2) which are meshed with each other. The worm (2) is connected with one end of a rotating shaft (3) through a flat key (4) and drives the rotating shaft (3). A gear (5) is fixedly arranged at the other end of the rotating shaft (3) and is in transmission with a rack shaft (6) in a meshed mode. A blade holder support (7) of a doctor blade is fixedly installed on the rack shaft (6). A handle wheel (8) is arranged on the worm (2). The doctor blade lifting mechanism is simple in structure and can meet the demand for adjusting the vertical direction of the doctor blade.
Description
Technical field
The utility model relates to printing industry, is specifically related to a kind of doctor elevating mechanism.
Background technology
Doctor is widely used in the print fields such as intaglio printing, letterpress, flexo, and doctor generally has the good mechanical performances such as blade is thin, intensity is high, toughness is better.
In the time that roller is rotated, roller is taken ink under doctor to, ink has the effect of a power to scraper, make doctor have the trend of outside rolling and be overcome by cylinder, and roller is imposed to certain pressure, ink outside roller forme is wiped off, and life-span and the print quality of the quality of doctor adjustment to doctor all has considerable influence.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of doctor elevating mechanism, to reach the object of doctor and roller lift adjustment demand.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of doctor elevating mechanism, comprises intermeshing worm gear 1 and worm screw 2, and described worm gear 2 is connected with rotating shaft 3 one end and transmission by flat key 4, and described rotating shaft 3 other ends are fixed with gear 5; Described gear 5 and rack shaft 6 engaged transmission, the tool support 7 of doctor is fixedly mounted on described rack shaft 6.
Further, described worm screw 2 is provided with handwheel 8.
By technique scheme, a kind of doctor elevating mechanism that the utility model provides, rotates handwheel, Worm Wheel System, and flat key is circumferentially fixed worm gear and rotating shaft, with transmitting torque; Rotating shaft is rotated, and the gear being fixed in rotating shaft can move up and down rack shaft, and tool support is housed on rack shaft, thereby the relative position of up-down adjustment doctor and roller meets different printing demand.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below.
Fig. 1 is the disclosed a kind of doctor elevating mechanism schematic diagram of the utility model embodiment.
Numeral in figure:
1, worm gear 2, worm screw 3, rotating shaft 4, flat key 5, gear
6, rack shaft 7, tool support 8, handwheel
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
With reference to figure 1, a kind of doctor elevating mechanism, comprises intermeshing worm gear 1 and the worm screw 2 that is provided with handwheel 8, and worm gear 2 is connected with rotating shaft 3 one end and transmission by flat key 4, and rotating shaft 3 other ends are fixed with gear 5; Gear 5 and rack shaft 6 engaged transmission, rack shaft 6 vertically arranges, and the tool support 7 of doctor is fixedly mounted on rack shaft 6.
With reference to figure 1, rotate handwheel 8, worm gear 1, worm screw 2 engaged transmission, the circumferentially fixing worm gear 1 of flat key 4 and rotating shaft 3, with transmitting torque; Rotating shaft 3 is rotated, and the gear 5 being fixed in rotating shaft 3 can move up and down rack shaft 6, and tool support 7 is housed on rack shaft 6, thereby the relative position of up-down adjustment doctor and roller meets different printing demand.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of above-described embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
