Concrete meaning in bright.Term " and or " used herein include the arbitrary of one or more relevant listed items and
All combinations.
It please refers to Fig.1 to Fig.3, the flexible printing press roller mechanism 10 that one embodiment of the invention provides, including roller central spindle 11,
Roller axle sleeve 12, bearing block 14, thread bush 15, worm gear 16, worm screw 17, roller motor 18, draws version motor 19, connection at roller seat 13
Axis device 20 and small shaft coupling 21;
It wherein is fixed with roller axle sleeve 12 as shown in Figure 1, being arranged on the left end outer wall of roller central spindle 11, roller central spindle 11
Right end is connected by shaft coupling 20 with the output shaft of roller motor 18, while the intermediate position of the roller central spindle 11 is set in axis
It holds in seat 14, further includes needle bearing 22 in the present embodiment further, specifically, its needle bearing 22 is set in roller axis
On the outer wall of core 11, and the needle bearing 22 is installed in bearing block 14.
Wherein, which is fixed on roller seat 13, further, in this embodiment, it further include straight line guide rail seat
23 and linear guide 24, wherein the roller seat 13 is fixedly mounted on straight line guide rail seat 23, which is mounted on perpendicular
In the linear guide 24 being directly arranged, straight line guide rail seat 23 can slide up and down in linear guide 24, the fixed peace of the linear guide 24
In the rack 25 of flexible printing press, user can be by driving straight line guide rail seat 23 to realize its flexible printing press roller mechanism 10 at this time
It moves up and down.
Wherein, which is set in bearing block 14, and is connected between the thread bush 15 and bearing block 14 by screw thread
It connects, further, which is fixedly connected with thread bush 15, and worm gear 16 and thread bush 15 are axially fixed in roller central spindle 11
On, further, worm gear 16 and worm screw 17 are sequentially connected, and worm screw 17 is mounted on roller seat 13.Further, the worm screw 17
One end pass through small shaft coupling 21 and draw the output axis connection of version motor 19.Further, connection is offered on the bearing block 14
Its internal through-hole correspond to the position of through-hole equipped with gas-tpe fitting 26 on the outer wall of bearing block 14.
In use, version motor is drawn to start to work for it so that its output shaft rotates, by the connection of small shaft coupling 21 so that driving
Dynamic worm screw 17 rotates, wherein since worm screw 17 and worm gear 16 are sequentially connected, since the rotation of worm screw 17 can drive worm gear
16 rotation is fixedly connected due to worm gear 16 with thread bush 15 at this time, and thread bush 15 is threadedly coupled with bearing block 14, therefore by
In worm gear 16 rotation so that can realize that thread bush 15 along the axial movement of bearing block 14, therefore can drive and thread bush 15 is fixed
The axial movement of the roller central spindle 11 of connection, realizes the assembly of horizontal direction.It is fixed by user's driving and roller seat 13 simultaneously
The straight line guide rail seat 23 of connection to vertically move along linear guide 24, realizes the assembly of vertical direction.
Further, pass through the work of roller motor 18 so that the rotation of its output shaft can be realized, pass through shaft coupling at this time
The connection of device 20 may make roller central spindle 11 to start turning, and roller motor 18 drives roller central spindle 11 to rotate at this time, due to roller
The left end of central spindle 11 is fixed with roller axle sleeve 12, therefore its roller axle sleeve 12 can be rotated together with roller central spindle 11.
Further, high pressure gas can enter to the sky between bearing block 14 and roller central spindle 11 by gas-tpe fitting 26
Intracavitary, high pressure gas is entered in the long stomata of roller central spindle 11 by cavity, and enters to roller along the roller central spindle 11
In cavity between central spindle 11 and roller axle sleeve 12, the finally gas outlet discharge through roller axle sleeve 12.
Flexible printing press roller provided by the invention mechanism passes through drawing version motor, worm gear, worm screw, thread bush and the bearing of setting
Seat can drive worm screw to rotate when so that drawing the work of version motor, worm gear and thread bush rotation be driven, so that the thread bush can be in bearing
Axial movement in seat, thus drive the horizontal direction for the roller central spindle being fixedly connected with thread bush mobile, simultaneously because setting
Roller seat, straight line guide rail seat and linear guide, so that it is vertically movable to may make that roller seat carries out, to drive roller central spindle
Vertical direction is mobile, so that being convenient for the assembly of horizontal direction and vertical direction, flexible printing press roller mechanism structure provided by the invention
It is compact, process and assemble is more convenient, saves processing, the expense of assembly and time, solving existing roller mechanism can not be preferable
The problem of adjusting.
