Abstract
The utility model relates to a printing machine ink scraper pressure adjusting device, which comprises an electronic display screen and a programmable controller which is connected with the electronic display screen, wherein the programmable controller is connected with a servo-motor, a power input gear is installed on a power output end of the servo-motor, an intermediate wheel is installed on a shaft end of an eccentric shaft which closely depends on a scraper seat, the power input gear is engaged with the intermediate wheel to drive the eccentric shaft to rotate, the intermediate wheel is also engaged with a power output gear, the shaft end of the power output gear is connected with an encoder, and the encoder is also connected with the programmable controller. The printing machine ink scraper pressure adjusting device adjusts the pressure through the eccentric shaft, a driving system is simple, only a simple wheel system is used to realize transmission, the pressure is keyed in through the electronic display screen, and the encoder feeds back to realize the digitalized pressure adjustment.
Description
Technical field
The utility model relates to a kind of pressure-regulating device, is specifically related to the pressure-regulating device between the doctor and ink roller in a kind of printing machine inking system.
Technical background
Doctor is the vitals in the printing machine inking system, and being influences the controlled condition that the ink transfer quality be can not ignore, and its effect is to scrape off printing ink unnecessary on the ink roller.In order to implement wiping accurately, squeegee pressure accounts for therein and plays a very important role, if pressure is too small, does not have the effect of wiping, causes the China ink amount of inking system too much, can not play even printing ink fast; If pressure is excessive, can not give and transmit enough China ink amounts in the inking system, the printing ink of Mo Lu system is condensed, the ink roller that can wear and tear when serious, but also can cause the printing ink below the doctor to produce packing phenomenon, influence the performance of inking system.At present, existing several doctor pressure-regulating devices are mainly observed by artificial going, and go by rule of thumb to regulate, and pressure regulation is inhomogeneous, and pressure is non-constant.What have is too complicated, has increased the manufacturing cost of machine, operation inconvenience.Therefore pressure regulating mechanism is for the performance of improving inking system accurately, and improving printing quality has important and practical meanings.
Summary of the invention
It is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, pressure regulation constant uniform scraping blade for printing machine pressure regulation device.
For achieving the above object, the technical solution adopted in the utility model is: comprise electronic display and the Programmable Logic Controller that is connected with electronic display, Programmable Logic Controller links to each other with servomotor, the clutch end of servomotor is equipped with power input gear, abut against on the axle head of scraping the eccentric shaft on the tool rest idle wheel is installed, power input gear and idle wheel engagement drive eccentric shaft and rotate, idle wheel also meshes with power output gear, the axle head of power output gear is connected with encoder, and encoder is connected with Programmable Logic Controller again.
Power input gear of the present utility model is identical with the geometrical structure parameter of power output gear.
The utility model is adjusted pressure by eccentric shaft, and transmission system is simple, has only used a simple train to realize transmission; By electronic display, key in pressure, encoder feedback realizes digitized pressure adjusting.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model user mode figure.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1,2, comprise electronic display 1 and the Programmable Logic Controller 2 that is connected with electronic display 1, Programmable Logic Controller 2 links to each other with servomotor 3, the clutch end of servomotor 3 is equipped with power input gear 4, abut against on the axle head of the eccentric shaft of scraping on the tool rest 10 7 idle wheel 5 is installed, power input gear 4 drives eccentric shaft 7 with idle wheel 5 engagements and rotates, idle wheel 5 also meshes with power output gear 6, the axle head of power output gear 6 is connected with encoder 9, encoder 9 is connected 2 with Programmable Logic Controller again, and power input gear 4 is identical with the geometrical structure parameter of power output gear 6.Eccentric shaft 7 is installed on the bearing on the wallboard, and eccentric shaft 7 nestles up scrapes tool rest 10, and scraping has fastening scraper 11 on the tool rest 10, and scraper 11 is to contacting with ink roller 12 surfaces.
When on electronic display 1, keying in a force value, force value is imported Programmable Logic Controller 2 into, change into the revolution of servomotor 3 through computing, make servomotor 3 rotate, the power input gear 4 in the servomotor 3 driven gear transmission systems rotates, and power input gear 4 drives idle wheel 5 and rotates, idle wheel 5 drives eccentric shaft 7 and rotates, force and scrape tool rest 10 swings, make scraper 11 extruding ink rollers 12 surfaces, reach digitized pressure and regulate; Simultaneously, because transmission system medium power input gear 4 is consistent with the geometrical structure parameter of power output gear 6, so the revolution of power output gear 6 has been represented the revolution of power input gear 4, the revolution of servomotor 3 just, the revolution of power output gear 6 is by 9 records of encoder, when reaching the predetermined number of turns, encoder 9 sends feedback command to Programmable Logic Controller 2, makes servomotor 3 shut down.
