Abstract

The utility model discloses dial register sets of a satellite flexo printing machine, which comprise a sliding sleeve installed on a frame. A sliding pole is arranged inside the sliding sleeve; a lead screw nut is coaxially installed inside the sliding pole; the lead screw nut is in sleeve connection with a precise ball screw; the precise ball screw is connected with an output end of a worm speed reducer; an adjusting hand wheel is installed at an input end of the worm speed reducer; the sliding pole is connected with a sliding block; and the sliding block is fixedly connected with a dial through a stud bolt. When the register sets are used for transverse register, a dial is sleeved on a plate roller shaft through a bearing. When the register sets are used for longitudinal register, the dial is sleeved on a spline housing through the bearing, and the spline housing is fixedly connected with a printing plate roller gear. The register sets have fine rigidity and easily ensured precision, eliminates axial clearance, enables device running to be more flexible, substantially prolongs the service life of parts, and is more convenient in assembly and disassembly, thereby remarkably improving precision of register overprinting, ensuring the printing quality of products and increasing production efficiency.

Background technology

For realizing the printing of polychrome fineness, one of its key link is exactly the chromatography between look and the look.Chromatography is to realize by axial location and the circumferential phase place of adjusting forme drum, promptly in the forme drum rotary course, by regulating the axial location that horizontal register sets changes forme drum, change the circumferential phase place of forme drum by regulating vertical register sets, make the certain chromatography accuracy rating of arrival between look and the look, its chromatography precision directly determines to print the exquisite degree of image.The realization of chromatography precision, its crucial technology just is on the register sets of machine. for register sets, and necessary stable, reliable, the easy adjusting of requirement, easy installing/dismounting; Under the state of forme drum rotation, must realize two actions: the first, by regulating, can make the axial displacement that edition roller produces to be needed; The second, by regulating the axial displacement that edition roller gear is needed to generation along the version roll shaft.

The existing piece formula of refuting mainly has the following disadvantages to register sets in length and breadth: 1) because in machine operation procedure, copper billet and shift fork pressing plate, shift fork are sliding friction, constantly wearing and tearing in the use, the gap affects machine chromatography precision of generation between pressing plate.2) stir support plate owing to be long cantilever slab, poor rigidity, easily vibration influences the machine chromatography precision in the operation process.3) to the version link plate owing to also be long cantilever slab, poor rigidity, yielding in the operation process, influence the machine chromatography precision.4) whole device is complicated, processing and matching requirements height.5) install, dismantle version roller complicated operation, difficulty.Therefore improve the chromatography precision, satisfy high-precision requirement, become the technical barrier that a urgent need overcomes.

Summary of the invention

The purpose of this utility model provides a kind of dial-type register sets of satellite-type flexible printing machine, has solved that the structural design that exists in the prior art is unreasonable, the chromatography precision does not reach high-precision problem.

The technical scheme that the utility model adopted is, a kind of dial-type register sets of satellite-type flexible printing machine, comprise rack-mounted sliding sleeve, be provided with traveller in the sliding sleeve, traveller can endwisely slip in sliding sleeve, is coaxially installed with feed screw nut in traveller, feed screw nut and precise ball screw socket, precise ball screw is connected with the output of worm reducer, at the input of worm reducer adjusting handle is installed; Traveller is connected with slide block, and slide block is fixedlyed connected by double-screw bolt with dial,

When being used for laterally to version, dial is contained on edition roll shaft by bearing holder (housing, cover);

When being used for vertically to version, dial is contained on the spline housing by bearing holder (housing, cover), and spline housing and forme drum gear connect firmly.

Characteristics of the present utility model also are:

The outer end of its middle (center) bearing is provided with two round nuts.

Wherein sliding sleeve and traveller are the revolution structure.

Device of the present utility model is the sliding sleeve slide block structure, has effectively increased structural rigidity, has improved production technology; The shift fork structure is set to dial device, becomes sliding friction into the bearing element friction, has improved part life, and has eliminated end play, has improved the seal precision; Stay big gap to compress between dial and slide block, only need compress or unclamp this screw rod with screw rod, just can easily installation or removal version roller, time is printed in shortening greatly, has improved operating efficiency; Before ball-screw, install worm speed reducer additional, improved the precision of regulating, guaranteed the printing quality of product.
