Abstract
The utility model discloses a kind of laser platemaker, to improve plate-making efficiency.Laser platemaker comprises support, holder, main shaft, roller, at least two laser carving devices, and the transmission device corresponding to each laser carving device, wherein: described holder is fixed on support, described spindle mounted is in holder, and described roller is sheathed on main shaft and by main shaft driven rotary; Described support is provided with guide rail for each laser carving device, and each laser carving device is slidedly assemblied on corresponding guide rail, can be driven mobile respectively by the transmission device of correspondence, to carve the different layout areas of roller.
Description
Technical field
The utility model relates to printing equipment technical field, particularly relates to a kind of laser platemaker.
Background technology
Offset printing and gravure are two kinds of the most common typographies.Wherein, the roller of gravure, printing is lower than blank parts, and the degree of printing depression is different with the level depth of image.During printing, roller rolls across to be coated with ink from black groove, and doctor scrapes off the ink of blank parts in roller, thus makes ink only be retained in the printing of depression.The top of roller is provided with impression cylinder, and stock, from process between roller and impression cylinder, is subject to the extruding of impression cylinder, thus stamps corresponding pattern.
The roller of gravure is generally metal roller, and space of a whole page pattern is formed by laser engraving.When roller comprises the different layout area of resolution ratio, adopt existing laser platemaker to need to carve each layout area one by one, plate-making efficiency comparison is low.
Utility model content
The object of the utility model embodiment is to provide a kind of laser platemaker, to improve plate-making efficiency.
The laser platemaker that the utility model embodiment provides, comprises support, holder, main shaft, roller, at least two laser carving devices, and the transmission device corresponding to each laser carving device, wherein:
Described holder is fixed on support, and described spindle mounted is in holder, and described roller is sheathed on main shaft and by main shaft driven rotary; Described support is provided with guide rail for each laser carving device, and each laser carving device is slidedly assemblied on corresponding guide rail, can be driven mobile respectively by the transmission device of correspondence, to carve the different layout areas of roller.
Alternatively, each laser carving device layout area resolution ratio of carving is different.
Preferably, described transmission device is belt drive unit.
In the technical scheme of the utility model embodiment, laser platemaker comprises at least two laser carving devices, can carve, compared to prior art the different layout areas of roller simultaneously, the time of engraving needed for roller greatly reduces, thus substantially increases plate-making efficiency.

Detailed description of the invention
In order to improve the plate-making efficiency of laser platemaker, the utility model embodiment provides a kind of laser platemaker.In the technical scheme of the utility model embodiment, laser platemaker comprises at least two laser carving devices, can carve, compared to prior art the different layout areas of roller simultaneously, the time of engraving needed for roller greatly reduces, thus substantially increases plate-making efficiency.
For making the purpose of this utility model, technical scheme and advantage clearly, by the following examples the utility model is described in further detail.
As depicted in figs. 1 and 2, the laser platemaker that the utility model embodiment provides, comprises support 1, holder 2, main shaft 3, roller 4, at least two laser carving devices 5, and each transmission device 6 corresponding to laser carving device 5, wherein:
Holder 2 is fixed on support 1, and main shaft 3 is assemblied in holder 2, and roller 4 is sheathed on main shaft 3 and by main shaft 3 driven rotary; Support 1 is provided with guide rail 10 for each laser carving device 5, and each laser carving device 5 is slidedly assemblied on corresponding guide rail 10, can be driven movement respectively, to carve the different layout areas of roller 4 by the transmission device 6 of correspondence.
The concrete quantity of laser carving device 5 is not limit, can be two, three or more.The layout area resolution ratio that each laser carving device 5 is carved can be identical, also can be different.In the prior art, if roller comprises the different layout area of resolution ratio, the laser carving device of laser platemaker needs to adjust resolution ratio after having carved a layout area, and then carves another layout area, and plate-making efficiency comparison is low.And in the technical scheme of the utility model above-described embodiment, no matter whether the resolution ratio of each layout area is identical, because multiple laser carving device can work simultaneously, this makes the time of carving needed for roller greatly reduce, thus improves plate-making efficiency.
The operation principle of laser carving device 5 is: the list bundle original laser produced by laser head, splits beam system be split into the superfine laser beam of multi beam through optics.Often restraint after laser beam modulated according to the bright feature such as secretly of image information in computer by acousto-optic modulator, become controlled light beam.Through focusing on, hundreds of bundle laser beam is directly mapped to roller surface and carves, thus etches required pattern.The diameter of laser beam and the light distribution shape of light beam, determine in the definition of roller surface institute etching pattern and resolution ratio.
As shown in Figure 1, the transmission device 6 corresponding to laser carving device 5 is belt drive unit.Particularly, the fixed mount of laser carving device 5 is slidedly assemblied on guide rail 10, and connects with the first belt 7a, and the first belt 7a is driven by the first motor 8a.After the first belt 7a is driven by the first motor 8a, laser carving device 5 can move setting displacement by opposite rail 10, aims at corresponding layout area carve to make engraving member.
As shown in Figure 1, the type of drive of main shaft 3 can be: main shaft 3 stretches out the end of holder 2 and a belt wheel 9 assembles, and belt wheel 9 is by the second belt 7b transmission, and the second belt 7b is driven by the second motor 8b.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
