Description
Technical field
The invention belongs to web printing roller design field, and in particular to a kind of rolling based on general expanding arbor
Jacket casing cylinder, can easily change printing format and transformation printing type, be advantageous to the technique diversity of printed matter with it is online from
Dynamicization.
Background technology
Current similar roller is mostly overall structure, and part is heavy, and majority uses conventional motors gear drive, is rolled for printing
The installation of cylinder and to lock up debugging process excessively complicated, and chromatography precision is had a great influence by the accuracy of gear；Meanwhile such a printing cylinder
Adaptation breadth is more single, if the size that product occurs can not effectively use whole printing surface, it may appear that blank is caused compared with billow
Take, increase production cost.
The content of the invention
For above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of drum sleeve based on general expanding arbor
Cylinder, using the use of simple tube-in-tube structure, and magnesium-aluminium alloy material, allow sleeve weight saving, carry lighter with replacing
Fast；The roller sleeves of various outer diameter adapt to the requirement of different breadths, more rationally effectively use the space of a whole page, beneficial to small list and
Miscellaneous single splicing, make efficiency highest, economic benefit maximum；Due to sleeve flexible transformation use, identical platform it is expansible go out more
More printing functionalities, lift its performance diversity.
The purpose of the present invention is achieved through the following technical solutions：A kind of roller sleeves based on general expanding arbor, bag
Sleeve and expanding arbor are included, it is characterized in that：Sleeve is made up of magnesium-aluminium alloy material, and the external diameter of sleeve can be different sizes,
Two steel bushings are provided with sleeve, the internal diameter size of steel bushing is unified specification and one bigger, and one smaller；Expanding arbor is unified
The multidiameter structure of specification, tapered end are provided with circular conical surface, and afterbody is cylindrical end and is provided with step inclined-plane, and having on expanding arbor can
The handle of rotation and the expansion section on two its deformable faces of cylinder, expanding arbor inside are provided with hydraulic oil, pass through rotating handles
Change hydraulic fluid pressure, the cylinder facial disfigurement at expansion section can be made, convert steel bushing and the interference of expanding arbor or gap coordinates
Relation.
The present invention uses unified specification mandrel, is connected using circular conical surface is self-centering, and afterbody cylindrical end auxiliary is fixed,
By benchmark at foregoing two, fix its operating position；The overall structure for using multi-diameter shaft, is more favorable for roller sleeves
Installation；Using the fixation of key resting barrel sleeve and mandrel relative position, i.e. zero-bit, and limit its axial position；Pass through change
It contacts the diameter dimension on the face of cylinder to shape, changes the matching relationship with roller sleeves, reaches and limit its axial movement, so as to ensure
The fixation and reset of the assembly relation and fitted position of roller sleeves and mandrel.
The fixation of roller sleeves and printing consumable material is broadly divided into two kinds, and one kind is that one kind is screw fastening using bonding mode
Tight mode.
Bonding mode：Which is mainly used in rubber sleeve, selects the cementitious blanket of fixed thickness size,
With reference to installation reference line, blanket is installed, and is sealed at abutment joint using glass cement, it is ensured that the use of blanket
Life cycle.
Screw-threaded coupling mode：Which is mainly used in plate cylinder, is made a plate using conventional PS versions, passes through special folding
Version frock, be molded plate, after be installed on plate cylinder, lock both sides screw, you can complete locing up for roller.
The present invention is connected using servomotor with roller mandrel, by control technology, reaches the accurate adjustment of zero-bit with setting
It is fixed.
The present invention has following advantage：
1）Based on platform, the printing demand of the different spaces of a whole page is suitable for；
2）Concrete operations are simple and efficient, and reset roller positioning precision is high；
3）Combination based on sleeve and platform, Function Extension power are strong；
4）Suitable for web offset technology；
5）It is advantageously implemented printing equipment linkageization and printing process automation.
Brief description of the drawings
Fig. 1 is that roller sleeves assemble the structural representation after steel bushing.
Fig. 2 is that rubber bushing roller assembles the structural representation after steel bushing.
Fig. 3 is that plate sleeve assembles the structural representation after steel bushing.
Label is described as follows in accompanying drawing：1- expanding arbors, the steel bushings of 2- first, 3- roller sleeves, the steel bushings of 22- second, 4-
One key, the keys of 5- second, 6- centering taper chucks, 33- blanket cylinders, 34- blankets, 36- plate sleeves, 37- stage clips, 38-PS
Version, 39- briquettings, 40- flush end trip bolts.
Embodiment
1）As shown in figure 1, sleeve is made up of magnesium-aluminium alloy material, the external diameter of sleeve can be different sizes, in sleeve
Provided with two steel bushings, the internal diameter size of steel bushing is unified specification and one bigger, and one smaller；Expanding arbor is unified specification
Multidiameter structure, tapered end are provided with circular conical surface, and afterbody is cylindrical end and is provided with step inclined-plane, first that expanding arbor is tapered
End is connected with the centering taper chuck of working cell, the position of the second key of alignment and taper chuck keyway, in the work of pneumatic cylinder
Under, the mandrel that pulling has round inclined-plane jacks up steel ball change assembling diameter, withstands cylindrical end step inclined-plane, reaching makes circular conical surface tight
Close fit and the purpose locked；Then roller sleeves there is into keyway end（That is the ends of size Ф 82）The ends of mandrel Ф 79.5 are first inserted in,
In the presence of multi-diameter shaft is oriented to, roller sleeves are installed in place, until the keyway and the first key in roller sleeves are assembled to position, axle
Finished to spacing.There is the expansion section on rotatable handle and two its deformable faces of cylinder on expanding arbor, in expanding arbor
Portion is provided with hydraulic oil, at the handle Ф 79.5 on rotary expansion mandrel, at increased in size Ф 80,82 liang of Ф（I.e. two deformable
At the expansion section on its face of cylinder）Inside pressure, make its size increase become, from the gap of steel bushing early stage and expanding arbor witing pass
System is changed into interference fit relation, is finally reached locking and the purpose of resting barrel sleeve and expanding arbor.So far sleeve and core
The assembly work of axle finishes, after the ends of Ф 30 are fixed into support installation locking, i.e. can be at can working condition for the roller sleeves.
2）The schematic diagram of rubber bushing roller is illustrated in figure 2, steel bushing can reduce expanding arbor expansion area and alloy is rolled
The tension force of cylinder, the change for causing cylinder sizes is avoided, bonding can use after can gluing blanket in butt-welded side seam position on surface
Glass cement, prevent the liquid such as fountain solution from penetrating into, improve blanket service life.
3）The schematic diagram of plate sleeve is illustrated in figure 3, its structure is identical with blanket cylinder, all using general steel bushing；
Its PS version can use conventional plate, this to make a plate it is cheap, it is convenient.
The above-mentioned roller sleeves based on expanding arbor, can using the magnesium alloy sleeve of supporting steel bushing and various outer diameter
To provide the printing format of sizes, very big lifting is suffered from for the rate of coming into force and cost savings, it is real due to its versatility
One-machine-multi-function is showed, the conversion of production task also becomes simple, and the labor intensity of worker is significantly reduced.
