Bottle printing positioning seat
Technical field
The invention belongs to printing equipment field, particularly a kind of bottle printing positioning seat.
Background technology
The positioning seat that present bottle printing technology adopts is rigid collision location, because the reason of technique, material, bottle deformation comparison is large, shrink uneven, easily cause location dimension unstable, during printing print content and the high and low position at the bottom of bottle inconsistent, cause bulk article printing position inconsistent; Even sometimes, because product does not enter position and causes positioning seat to damage, and common positioning seat is all integral type, needs integral replacing after damage, increases production cost.
Summary of the invention
The bottle printing positioning seat that the present invention is directed to the rigidity of current integral type cannot adapt to product size error, spoilage is high, replacement cost is high deficiency, provide a kind of bottle printing positioning seat of split type flexibility, this bottle printing positioning seat adopts spring flexible principle, product introduction pre-determined bit state is made during product operation, spring and ball bearing guide bushing is adopted to make product enter positioning states accurately and stably again, the design can be applicable to product diameter error 0-5mm scope, bulk article printing position is consistent, replacing frock is simple, saves cost.
A kind of bottle printing positioning seat, it comprises pedestal, contiguous block, limited block, movable part, bolt one, spring and ball bearing guide bushing, wherein, contiguous block is enclosed within pedestal, and movable part is enclosed within contiguous block, is provided with spring and ball bearing guide bushing between movable part and contiguous block, spring plays the effect of damping and reset, ball bearing guide bushing plays the effect of guiding, and limited block is located at above the middle part of contiguous block and movable part, and is fixed on pedestal by bolt one; The upper surface of movable part is higher than limited block, and the upper end medial surface of movable part has chamfering, to adapt to bottle body bottom owing to being out of shape the size difference caused.
In a kind of bottle printing of described one positioning seat, described movable part comprises movable block and locating piece, movable block is enclosed within contiguous block, spring and ball bearing guide bushing is provided with between movable block and contiguous block, locating piece is fixed on above movable block by bolt two, the upper surface of locating piece is higher than limited block, and the upper end medial surface of locating piece has chamfering, to adapt to bottle body bottom owing to being out of shape the size difference caused; Cause the damage of locating piece in bottle and locating piece contact process, or because product batches is different, the diameter of bottle changes, only need change locating piece, enhance productivity, reduction production cost.
Bottle printing positioning seat of the present invention, when fixing bottle, the chamfering place inside movable part upper end first touches bottle body bottom, and the rear spring that is under pressure produces deformation, movable part position is moved down, until the bottom of bottle touches the upper surface of limited block; After printing terminates, bottle leaves positioning seat, and movable part will reset under the action of the spring.The chamfering of movable part upper end can adapt to the size distortion of bottle, Flexible Design can absorb collision during location, reduce the risk that positioning seat damages, the split-type design of movable part, after locating piece is damaged, or when bottle size changes, also can change locating piece rapidly, enhance productivity, reduce production cost.

Detailed description of the invention
Contrast accompanying drawing below, by embodiment, the invention will be further described.
With reference to accompanying drawing 1, , in the specific embodiment of bottle printing positioning seat of the present invention, this bottle printing positioning seat comprises pedestal 1, contiguous block 2, limited block 3, movable block 4, locating piece 5, bolt 1, bolt 27, spring 8 and ball bearing guide bushing 9, wherein, contiguous block 2 is enclosed within pedestal 1, movable block 4 is enclosed within contiguous block 2, spring 8 and ball bearing guide bushing 9 is provided with between movable block 4 and contiguous block 2, spring 8 plays the effect of damping and reset, ball bearing guide bushing 9 plays the effect of guiding, locating piece 5 is fixed on above movable block 4 by bolt 27, limited block 3 is located at contiguous block 2, above the middle part of movable block 4 and locating piece 5, and be fixed on pedestal 1 by bolt 1, the upper surface of locating piece 5 is higher than limited block 3, and the upper end medial surface of locating piece 5 has chamfering, to adapt to bottom bottle 10 owing to being out of shape the size difference caused, cause the damage of locating piece 5 in bottle 10 and locating piece 5 contact process, or because product batches is different, the diameter of bottle 10 changes, and only need change locating piece 5, enhance productivity, save production cost.
With reference to accompanying drawing 2, utilize bottle of the present invention to print positioning seat when fixing bottle, the chamfering place inside movable part upper end first touches bottle body bottom, and the rear spring that is under pressure produces deformation, the position of movable block and locating piece is moved down, until the bottom of bottle touches the upper surface of limited block; After printing terminates, bottle leaves positioning seat, and movable block and locating piece will reset under the action of the spring.
