Description
Technical field
The invention belongs to printing machine or the general purpose accessories of machinery, specifically disclose a kind of printing mechanism.
Background technique
Printing is to arrive printing ink transfer through processes such as plate-making, Shi Mo, pressurizations the original copys such as text, picture, photo, anti-fake
On the material surfaces such as paper, fabric, plastic products, leather, the technology of batch duplicating original copy content.Printing is through audit approval
Galley is transferred to the process of stock by printing machinery and ink special.
At present in printing process, usually first ink is coated on printing roller by ink-supplying mechanism, then by scraping
Knife strikes off extra ink, and the ink for avoiding printing roller surface from coating is uneven and influences printing quality.
Structure is complicated for existing printing mechanism, needs to be made of mechanisms such as ink supply roller group, printing roller and scrapers, therefore body
Product is huge, high to the area requirements of work-yard, causes the raising of production cost.
Summary of the invention
The invention discloses a kind of printing mechanisms, it is therefore intended that body caused by solving existing printing mechanism structure is complicated
The big problem of product.
Base case of the invention are as follows: a kind of printing mechanism, including printing roller, the printing roller are equipped with and printing
The arc inking cover that roller surface profile matches, there are the gap for ink flow between the inking cover and printing roller,
It is equipped with cavity inside the printing roller, is equipped with even ink portion, ink feed portion, ink-jet portion and driving portion in the cavity；
The driving portion includes driving gear, driven gear and the driven gear ring for forming planetary gear train, the driven gear
It is coaxially disposed with driven gear ring, the driving gear is engaged with driven gear and driven gear ring respectively, and the driving gear is fixed
It is connected with drive shaft, the drive shaft other end is fixedly connected with motor, and the gear ring is fixedly connected with cavity inner wall；
The even ink portion includes shaft, and the shaft is equipped with agitating plate, and coaxially fixation connects for the shaft and driven gear
It connects；
The ink feed portion is set in shaft, and the ink feed portion is for being filled with ink into cavity；
The ink-jet portion includes the inkjet mechanism on print roller side wall and is set to inking cover close to printing roller one side
On trigger mechanism.
Technical principle and beneficial effect of the invention is:
1. the present invention is by driving gear, driven gear and the driven gear ring of setting composition planetary gear train, so that working as motor
After driving driving gear by drive shaft, driving gear drives driven gear and driven gear ring in turn, so that driven gear
It is opposite with driven gear ring to invert, so that printing roller reversion opposite with shaft and agitating plate, so that the ink in cavity
Water is stirred plate and stirs evenly, and avoids the coloured particle in ink from depositing and causes ink color uneven.
2. the present invention is by setting inking cover and ink-jet portion, so that the inkjet mechanism when printing cylinder surface is turned to and is applied
When trigger mechanism on ink cover contacts, trigger mechanism triggers inkjet mechanism, so that the ink in cavity is sprayed from inkjet mechanism,
So that ink sprays into the gap between inking cover and printing roller, so that ink is between inking cover and printing roller
It is flowed in gap, and is equably applied to printing roller surface with the continuous rotation of printing roller, and due to applying
Gap size between ink cover and printing roller is fixed, therefore the ink thickness being applied on printing roller surface is also fixed, and is protected
Ink being uniformly distributed on printing roller surface is demonstrate,proved.
3. even ink portion, ink feed portion, ink-jet portion and driving portion are set in cavity by the present invention by being arranged, relative to existing
Printing machine, structure of the invention is compact, the demand to work-yard size is reduced, so that manufacturer is large-scale without leasing
Place, to reduce production cost.
Further, the annular boss extended to through-hole central axes, institute are equipped in the through-hole of printing roller outer wall side
It states annular boss inner wall and slidably connects the baffle pushed by trigger mechanism, be provided with jet orifice on the baffle, the ring-type is convex
Platform is hinged with support rod close to printing roller central axes on one side, is equipped with described in the first pressure spring and props up between the baffle and support rod
Strut is fixed with elastic rubber layer close to through-hole wall side, and for the elastic rubber layer in coniform, elastic rubber layer diameter is big
One end close to annular boss, the small one end of the elastic rubber layer diameter is stretched out logical to the direction close to printing roller central axes
Hole, described lesser one end of elastic rubber layer diameter are equipped with ink-feeding hole.By above-mentioned design, so that when through-hole is with printing roller
When turning at trigger mechanism, trigger mechanism pushes baffle along through-hole is axial to close to printing roller central axes direction, makes
Support rod is obtained to strut elastic rubber layer, so that elastic rubber layer is stretched close to printing roller central axes one end, so that
Ink-feeding hole is softened, so that the ink in cavity enters in elastic rubber layer, with the rotation of printing roller, when through-hole leaves touching
After sending out mechanism, under the action of the first pressure spring, baffle return, so that support rod is no longer strutted by baffle, so that elastic rubber
Glue-line bounces back under own resilient effect, so that the ink in elastic rubber layer is sprayed from jet orifice.
Further, the trigger mechanism includes being set to groove of the inking cover in printing roller one side, in the groove
Equipped with steel ball, the second pressure spring is fixed between the steel ball and groove.By above-mentioned design, so that working as steel ball and through-hole alignment
When, steel ball pushes baffle to the direction close to printing roller central axes under the action of the second pressure spring.
Further, be equipped with ink feed chamber inside the shaft, the shaft side wall is equipped with ink hole, the shaft far from from
One end of moving gear stretches out printing roller and is connected with ink inlet tube, rotary seal between the shaft and printing roller.By upper
Design is stated, so that ink enters in the ink feed chamber in shaft from ink inlet tube, and then is flowed into cavity from ink hole.
Further, it is equipped with partition in the cavity, driving chamber, the drive are surrounded between the partition and printing roller end face
Moving gear, driven gear and driven gear ring are set in driving chamber.By above-mentioned design, so that driving portion passes through partition and ink point
From avoiding ink from impregnating driving portion, the particulate matter in ink enters the engagement between driving gear, driven gear and driven gear ring
Place, so that wearing the problem of increasing between driving gear, driven gear and driven gear ring.
Further, the printing roller surrounds the driving through-hole for being provided on the end face of driving chamber and stretching out for drive shaft, described
Through-hole radius is driven to be equal to drive shaft central axes to the sum of the distance of printing roller central axes and drive shaft radius, the driving is logical
Hole and printing roller are coaxially disposed.By above-mentioned design, so that when printing roller rotation, motor will not turn with printing roller
It is dynamic.
