Abstract
The utility model relates to a dynamic scraping blade which is mounted on a fixed shaft. The two ends of the fixed shaft are mounted on lateral brackets of a printing machine; a printing roller and a pressing roller are mounted on the lateral brackets of the printing machine; a scraping blade is mounted aside the printing roller and the pressing roller; the lower end of the scraping blade is clung to the surface of the printing roller; an ink plate is mounted under the printing roller; a fixed wheel is mounted on a shaft end, which extends out of the corresponding lateral bracket of the printing machine, of the fixed shaft; a neck is designed on the fixed wheel; a speed-adjusting motor is mounted on one lateral bracket, corresponding to the fixed wheel, of the printing machine; an eccentric wheel is mounted at the shaft end of the speed-adjusting motor; the eccentric wheel is mounted in the neck of the fixed wheel. According to the technical scheme, the scraping blade is driven to swing when the eccentric wheel at the shaft end of the speed-adjusting motor is rotated, and the dynamic compact contact is formed between the scraping blade and the printing roller. The scraping blade on the printing roller is kept under a moving state, so that foreign matters are prevented from being blocked on a contact surface of the scraping blade and the printing roller and from forming ink marks, no printing mark is formed on a presswork, and the quality of the presswork is greatly promoted.
Description
Technical field
The utility model belongs to printing equipment technical field, relates to a kind of dynamic doctor.
Background technology
In prior art, print roller and hold-down roller are installed on the side stand of printing machine, doctor is arranged on print roller and hold-down roller side, the lower end of doctor is close to print roller surface, doctor is fixedly mounted on fixed axis with fixed mount, the two ends of fixed axis are arranged on the side stand of printing machine, under print roller, disc are installed.This printing machine, the lower end of doctor is close in print roller, position is fixed, when snapping in small foreign matter between print roller and doctor, foreign matter can mark the inhomogeneous black trace of China ink layer one in print roller, this black trace can reprint on the product being printed and form impression, affects printing product quality.
Summary of the invention
In prior art, the doctor position being arranged on press printing roller is fixed, and easily snaps in small foreign matter between doctor and print roller, causes one inhomogeneous black trace of China ink layer of formation in print roller, this black trace reprints on the product being printed can form impression, affects printing product quality.For this problem, the utility model provides a kind of dynamic doctor, doctor is fixedly mounted on fixed axis with fixed mount, the two ends of fixed axis are arranged on the side stand of printing machine, print roller and hold-down roller are installed on the side stand of printing machine, doctor is arranged on print roller and hold-down roller side, the lower end of doctor is close to print roller surface, disc is installed below print roller, stretch out on the spindle nose of printing machine side stand one end of fixed axis, a fast pulley is installed, on fast pulley, be designed with draw-in groove, on the side stand of printing machine, buncher is installed, an eccentric wheel is installed on the spindle nose of buncher, eccentric wheel is arranged in the draw-in groove of fast pulley.
Adopt technique scheme, when the adjustment motor on being arranged on printing machine side stand slowly runs, eccentric wheel on its spindle nose promotes fixed axis and swings in draw-in groove, fixed axis drives doctor to swing, between scraper and print roller, form dynamic close contact, because doctor keeps mobile status in print roller, foreign matter can not be stuck on the contact-making surface of doctor and print roller and form black trace.Therefore, present technique has solved the problem that forms impression due to black trace on printed matter, and printing product quality improves greatly.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
