Description
Technical field
The invention belongs to the printing equipment technical field, relate to a kind of forme roller gapless driving jockey, be specially adapted to polychrome group intaglio printing press.
Background technology
Printing machine in the polychrome group is equipped with many group printing plate cylinders, and is when carrying out process printing that the colour cell pattern chromatography on each printing plate cylinder is accurate, just can print off clearly pattern.The relative position of color lump and be rotatably assorted very greatly on the impact of chromatography precision on each printing plate cylinder, the relative position of color lump is subjected to forme to add the impact of the factors such as physical dimension, the precision when installing and working environment in man-hour on each printing plate cylinder; The transmission quality of fit is affected by the fit clearance of the transmission connection piece between each printing plate cylinder.At present, power transmission shaft and the whole kind of drive that drives each roller of gear-box are mainly adopted in transmission on the multicolour press, by the uni-drive gear box that is driven one by one each roller behind the main motor outputting power by power transmission shaft, by the external gear on the drive of the internal gear on the uni-drive gear box output shaft roller, drive printing plate cylinder by external gear and rotate.In this transmission process, because between power transmission shaft and the gear-box, can't have the working clearance between the internal gear on the gearbox output shaft and the forme shaft head gear with avoiding, there is driving error in the work of each roller in the transmission process, and the transmission distance is longer, error is larger, and each roller is difficult to accomplish synchronously.Eliminating driving error will adjust the running part of whole production line, and the position of roller is adjusted, and its work difficulty is larger; And at the printing machine adjusted after normal operation a period of time, owing to being vibrated and the objective factor such as friction affects, driving error easily occurs again, affects printing precision.
Summary of the invention
The present invention is directed in the prior art, the printing machine of polychrome group adopts power transmission shaft and gearbox drive mode, the link of transmission is more, larger on the printing precision impact, and the problem that driving error is difficult to adjust, a kind of forme roller gapless driving jockey is provided, be installed on the frame of printing machine, the correspondence position of forme roller spindle nose, this device is by gripper shoe, slide rail, bearing slider, fixed case, servomotor, shaft joint, connecting axle and cylinder form, gripper shoe is installed in the frame side of printing machine, vertical with frame, in gripper shoe slide rail is installed, fixed case is installed on the slide rail, be connected with bearing slider between fixed case bottom and the slide rail, end at fixed case is installed servomotor, the rotating shaft of servomotor is goed deep in the fixed case, and the rotating shaft spindle nose is equipped with shaft joint, and the other end of shaft joint is installed connecting axle, bearing is passed at the middle part of connecting axle, is designed with the fixed cover of forme roller spindle nose on the termination of connecting axle; Be processed with the connection recess on the forme roller spindle nose of printing machine, connect recess and be sleeved in the fixed cover; Cylinder is installed in gripper shoe one end, and the cylinder axis of cylinder is installed in the fixed case lower end side.
Fixed cover is comprised of pedestal and kink two parts, two parts are semicircle axle sleeve, inner face at pedestal is processed with cotter way, half of pin is stuck in this cotter way, and pedestal is connected with connecting axle, and kink is screwed on pedestal, be processed with boss at kink, boss is stuck in the connection recess of forme roller spindle nose, has cotter way on the end face of forme roller spindle nose, and second half of pin is stuck on this cotter way.
Shaft joint is a buffer-type shaft joint that damping fin is installed.
After adopting this device, the rotating shaft of servomotor is directly connected on the spindle nose of printing plate cylinder with fixed cover, spindle nose at each printing plate cylinder is independently installed a servomotor, eliminated the roller driving error that easily causes with power transmission shaft and gearbox drive mode, the rotation of every servomotor is directly controlled rotating speed on demand by the master control computer of printing machine, makes the transmission of each roller cooperate more accurate; Servomotor can carry out simultaneously speed change and start and stop, and the mechanical shock of whole transmission system reduces greatly, and the error that mechanical shock causes reduces.
Owing to adopting spindle nose with printing plate cylinder to wrap in design in the fixed cover, establish groove on the spindle nose, groove is stuck on the boss of fixed cover, and the end face of spindle nose and fixed cover is located with pin, the pedestal of fixed cover and movable sleeve are firmly fixing with screw, therefore, fixed cover is connected closely with spindle nose, causes the gap of error almost not have.
Because employing buffer-type shaft joint is connected between the connecting axle of the rotating shaft of motor and printing plate cylinder spindle nose, in the sudden change of the rotating speed of motor or printing plate cylinder and change when larger, micro-deformation can occur in the buffer-type shaft joint, the torsion of buffering rotating shaft, greatly reduce the rigidity damage of connecting axle and relevant driving member, guarantee the complete machine normal operation.
Owing to adopting slide rail to support fixed case in gripper shoe, with bearing slider connecting sliding rail and fixed case, promoting whole device at fixed case side installation cylinder moves forward and backward, therefore, when changing forme or maintenance of equipment, this device can move forward and backward, for the maintenance and installation abdicate more spaces, easy to installation and maintenance.
