A kind of scraper-knife grinder
Technical field
This utility model relates to the technical field of screen printing apparatus, specifically a kind of scraper-knife grinder, particularly to its mechanical connecting structure.
Background technology
Traditional cutter elevating mechanism flexibility ratio scraping scraper-knife grinder is not high, and easily break down, at the bottom of the carrying dynamics of frame, and positioning precision is not high, the designing requirement of high accuracy screen printing device cannot be met, therefore need nonetheless remain for existing scraper lift mechanism is further improved.
Summary of the invention
The purpose of this utility model is in that to provide a kind of scraper-knife grinder, it adopts teeth bar type up-down mechanism complex equilibrium gas bar, it is effectively improved the integrated carrying intensity of frame, also contribute to promote the stability of jacking system, guaranteeing equipment stability at work, being provided with of alignment pin helps lifting operation precision.
To achieve these goals, the technical solution of the utility model is: a kind of scraper-knife grinder, it is characterized in that: it includes the frame that transverse horizontal is arranged, frame is respectively equipped with a main drive gear and a passive transmitting gear near two ends place, it is connected by chain between main drive gear with passive transmitting gear, frame place is provided with a motor, the end of the output shaft of motor is provided with a motor-driven wheel, this motor-driven wheel is connected with belt pulley by driving belt, this belt pulley and above-mentioned main drive gear are arranged at the two ends of same rotating shaft, the side of frame is longitudinally provided with a lifter rack, this lifter rack surface distributed has teeth, the teeth on the teeth of travelling gear and lifter rack surface engage each other, the side of frame is longitudinally provided with air pressure balance bar, the upper horizontal of frame is provided with a doctor blade holder, one end of doctor blade holder is connected with air pressure balance bar upper end, the other end of doctor blade holder is connected with lifter rack upper end, this doctor blade holder place is provided with a scraper along doctor blade holder trend and connects axle, one end of pincerlike scraper is connected axle and connects with scraper, the other end of pincerlike scraper is unsettled downwards, doctor blade holder place is to having two alignment pins, frame be connected with switch board, switch board edge is provided with the control panel protruding from switch board, corner, the bottom place of switch board is respectively provided with an angle.
The utility model discloses a kind of scraper-knife grinder, the utility model has the advantage of: (1) is skillfully constructed, implementation cost is low, maintenance and repair cost is low; (2) loading capacity is promoted big, stable working state; (3) control accuracy is high, accurate positioning.
