Description
Technical field
It the utility model is related to a kind of blanket cylinder for printing and being applied on gold stamping device.
Background technology
On printing gold stamping device, with roller or the blanket cylinder of gold stamping contacting dies, the clamping process of rubber is being carried out
Middle operation is comparatively laborious, so structure is also more complicated, can not ensure the clamping quality of rubber very well, so influence printing or
Gold stamping quality.
The content of the invention
In view of the problem of currently known technology is present, the technical problems to be solved in the utility model is to be to provide a kind of knot
Structure is simple, quick-clamping of the rubber on blanket cylinder can be achieved, and ensure the blanket cylinder of clamping quality.
The utility model is implemented by the following technical programs：
Blanket cylinder, including roller tube, roller tube are provided with gap slot in a circumferential direction, the left and right in gap slot point
Left jaws rotating shaft and right jaws rotating shaft are not set, and the axle both ends of left and right jaws rotating shaft are turned by the front and back end cover plate of roller tube
Dynamic supporting, it is characterised in that：The shaft end of left jaws rotating shaft connects the first worm gear, and the shaft end of right jaws rotating shaft connects the second worm gear,
Middle worm screw is provided among first, second worm gear, middle worm screw is rotated on bearing, cover board of front end of the bearing in roller tube
Outside is fixedly mounted.
Gib block, the front and rear setting installation counterweight of gib block are provided with gap slot in the centre position of left and right jaws rotating shaft
Block, the left surface of the relatively left jaws rotating shaft of balancing weight, which has, matches the cylindrical left cambered surface of left jaws rotating shaft, left cambered surface and left jaws
Left side gap is reserved between rotating shaft is cylindrical and fills rubber, the right flank of the relatively right jaws rotating shaft of balancing weight just by blanket cylinder
The right cambered surface cylindrical provided with right jaws rotating shaft is matched, right cambered surface and right jaws rotating shaft it is cylindrical between reserve right side gap just by
Blanket cylinder fills rubber.
After adopting the above technical scheme, the utility model is simple in construction, only need to be by rubber when carrying out the clamping work of rubber
The head of skin and afterbody are respectively put into the jaws of left and right jaws rotating shaft and blocked（The head of rubber and afterbody are being put into jaws
Preceding configured fastener）, then rotating forward worm screw can make that left jaws rotating shaft rotates clockwise and right jaws rotating shaft is counterclockwise
Rotate, and then rubber is tensed to and pinned the quick-clamping on the surface of roller tube, realizing rubber on blanket cylinder, and protect
Demonstrate,prove clamping quality.Further, the setting of balancing weight can not only ensure dynamic balancing of the roller tube when working rotation, prior
It is that the cambered surface design of balancing weight left and right side, the rubber end that left and right jaws rotating shaft is clamped can be made by balancing weight left and right sides
During the lower section in face, after being flattened by cambered surface with the outer round surface of left and right jaws rotating shaft is smooth is bonded, it is more preferable to ensure clamping quality.
Brief description of the drawings
The utility model has drawings described below：
Fig. 1 is structural representation of the present utility model.
Embodiment
The relevant details and operation principle of the utility model specific embodiment are described in detail below in conjunction with the accompanying drawings：

Right jaws rotating shaft 3 has jaws 31, and the axle both ends of left and right jaws rotating shaft are carried out rotating branch by the front and back end cover plate of roller tube 1
Hold, the shaft end of left jaws rotating shaft 2 connects the first worm gear 5, and the shaft end of right jaws rotating shaft 3 connects the second worm gear 8, first, second snail
Middle worm screw 9 is provided among wheel, middle worm screw 9 is rotated on bearing 6, and bearing 6 is solid on the outside of the cover board of front end of roller tube 1
Dingan County fills.Gib block 7, the front and rear setting installation counterweight of gib block 7 are provided with gap slot in the centre position of left and right jaws rotating shaft
Block 4, the bottom of balancing weight 4 is provided with the guide groove of matching gib block 7, to ensure installation accuracy；The relatively left jaws rotating shaft 2 of balancing weight 4
Left surface have and match the cylindrical left cambered surface 41 of left jaws rotating shaft 2, left cambered surface 41 and left jaws rotating shaft 2 it is cylindrical between reserve a left side
Side clearance fills rubber just by blanket cylinder, and the left side gap is slightly larger than rubber thickness 0.5-1mm, the phase of balancing weight 4
The cylindrical right cambered surface 42 of the right jaws rotating shaft 3 of matching, right cambered surface 42 and right jaws rotating shaft 3 are provided with to the right flank of right jaws rotating shaft 3
Right side gap is reserved between cylindrical and fills rubber just by blanket cylinder, the right side gap is slightly larger than rubber thickness 0.5-1mm
.
