Description

The front edge paper feed mechanism of servo corrugated paper plate printing machines

Technical field

The utility model belongs to the paper advance mechanism of a kind of servo corrugated paper plate printing machines in the printing machinery technical field.

Background technology

Along with the growing and continuous progress in science and technology of press, also more and more higher to the specification requirement of printing machinery.In known technology, the paper advance mechanism of existing servo corrugated paper plate printing machines mainly contains three kinds of structures: the one, chain structure, employing be the paper feeding mode that sprocket wheel, chain drive push away paper, shortcoming is that chain is elongated in operation easily, low precision; The 2nd, the push-plate type structure, employing be after play the paper feeding mode that pushes away cardboard, limit by its structure, the error of rushing board mechanism is bigger, especially can't normally send into for the cardboard of warpage at all, has a strong impact on presswork; The 3rd, the whole carriage lifting structure of mechanical cam and pneumatic control, shortcoming is to adopt the lifting of solenoid control cylinder, promote the lifting of whole paper feeding frame, its structure is complicated, especially in high-speed cruising, the switch time of magnetic valve and the inflation of cylinder, evacuation time, directly serious the lifting process of paper feeding frame, often cause paper feeding to incur loss through delay, deviation is bigger, the extremely high-precision printing of incompatibility, and heavy paper feeding bin lifting repeatedly, impact bigger to the device in the gear, cause service life short, part replacement is frequent, directly influences normal presswork, the production cost height also brings inconvenience to use.

Summary of the invention

In order to overcome the deficiency of prior art, the paper advance mechanism that solves existing servo corrugated paper plate printing machines starts the problem that error is big, be unsuitable for the high accuracy printing, and the utility model provides a kind of novel structure, reasonable in design, can eliminate the startup error, follow the tracks of the print speed printing speed of print roller synchronously, adapt to high-precision printing, and long service life, production cost is low, and printing quality is excellent, technical merit advanced person, operate simple and easy, easy to use new-type servo corrugated paper plate printing machines paper advance mechanism.

The technical scheme in the invention for solving the above technical problem is:

A kind of front edge paper feed mechanism of servo corrugated paper plate printing machines, it is provided with: mechanical part and electrical appliance part two parts are altogether formed.Mechanical part comprises: print roller, encoder, the high speed optoelectronic switch, the PU wheel, SERVO CONTROL drives electrical equipment, servomotor, transmission mechanism, the paper feeding wheels, power input wheel and planetary reduction gear frame, roll shaft portion in print roller is equiped with encoder respectively, the planetary reduction gear frame, and quicken the pacemaker place at the roll body of print roller and be fitted with the high speed optoelectronic switch, load servo-drive control apparatus on the paper feeding frame, the servo-drive control apparatus connects the high speed optoelectronic switch respectively, encoder, servomotor, the output shaft of servomotor connects PU wheel and power input wheel respectively by transmission mechanism, power input wheel connects the paper feeding wheels, the planetary reduction gear frame, print roller, between the left end rubber tire of the feed roller of print roller bottom and PU wheel is with the beans-and bullets shooter accelerating region, and PU wheel top is deceleration area in the right-hand member section that is positioned at the cardboard wide cut.Electrical appliance part comprises: encoder; the high speed optoelectronic switch; servomotor and by breaker protector; Switching Power Supply; touch-screen; Programmable Logic Controller; the SERVO CONTROL module; the SERVO CONTROL that the SERVO CONTROL driver connects to form drives electrical equipment; the breaker protector that SERVO CONTROL drives electrical equipment connects and the connecting and disconnecting of gauge tap power supply and controlled programmable controller power supply; Switching Power Supply connects touch-screen and provides dc source for it; encoder connects respectively with Programmable Logic Controller with the high speed optoelectronic switch and is connected; touch-screen is connected with the Programmable Logic Controller communication; Programmable Logic Controller is also connecting the SERVO CONTROL module; the SERVO CONTROL module connects the SERVO CONTROL driver, and the SERVO CONTROL driver connects another breaker protector and servomotor respectively.

The utility model be the high-velocity electrons that adopt pounce on catch, the front edge paper feed new structure of the servo tracking of separate unit, preposition acceleration point, eliminate and start error, to the print speed printing speed of following the trail of print roller synchronously, do and the closely-related S curvilinear motion of printing pitch, long at three kinds of different paper, move according to three kinds of S curves automatically.Consult accompanying drawing 3-accompanying drawing 5, one, the operation curve of the cycle pitch π D of cardboard length＜print roller; The 2nd, the operation curve of the cycle pitch π D of cardboard length=print roller; Three is that the cycle pitch π D of cycle pitch π D＞cardboard length＞print roller of 2 times of print roller is every the operation curve of opening mode.In the self-operating operation, when print roller forwards the acceleration start-up point to, servo controller is according to the printing plate cylinder speed of service of current encoder feedback, carry out preposition with beans-and bullets shooter acceleration startup in conjunction with the fixing relevant S curve of printing pitch π D, when reaching with beans-and bullets shooter, the linear velocity of PU wheel linear velocity and print roller is consistent, in reaching zone deceleration time, motor carries out the S curve and runs slowly, and stops after reaching the cardboard width.

Because technique scheme has been adopted in the utility model design, the paper advance mechanism that has effectively solved existing servo corrugated paper plate printing machines starts the problem that error is big, be unsuitable for the high accuracy printing.Show that through testing result on trial for several times it compared with prior art has novel structure, reasonable in design, can eliminate the startup error, follow the tracks of the print speed printing speed of print roller synchronously, adapt to high-precision printing, and long service life, production cost is low, and printing quality is excellent, technical merit advanced person, operate advantages such as simple and easy, easy to use.It is applicable to various servo corrugated paper plate printing machines, is a kind of novel servo corrugated paper plate printing machines paper advance mechanism.
