Abstract
The utility model discloses a printing plate roller for flexographic printing, it includes that printing plate dabber roller and cover establish the printing plate sleeve outside printing plate dabber roller, the first end of printing plate dabber roller is installed on one can dismantle the bearing frame, the second end of printing plate dabber roller is installed on a bearing frame, the second end cavity of printing plate dabber roller and with air cock intercommunication, dabber roller focus guiding mechanism is installed in the bearing frame outside. In the time will changing the printing plate, only need dismantle the bearing frame on the printing plate dabber roller first end, then utilize dabber roller focus guiding mechanism to make it not keep the focus steadily, do not drop to the second end application of force, labour saving and time saving has improved work efficiency.
Description
Technical field
The utility model relates to printing mechanism field, particularly relates to a kind of flexographic printing forme drum.
Background technology
Flexible printing uses flexible printing forme, the mode being transmitted ink by anilox roller is printed, during printing, certain thickness ink layer is coated on forme inking part by anilox roll equably, then under the effect of forme drum and impression roller, make the ink layer of inking part transfer to the surface of stock, form picture and text clearly.Tradition flexographic printing forme drum just adopts pneumatic jack axle construction or Pneumatic core shaft structure mostly, whole forme drum need be pulled down together with mandrel, waste time and energy when changing forme.
Summary of the invention
The purpose of this utility model is to provide a kind of easy-to-dismount flexographic printing forme drum.
The technical scheme realizing the utility model object is: a kind of flexographic printing forme drum, it comprises forme mandrel roller and is set in the plate sleeve outside forme mandrel roller, the first end of described forme mandrel roller is installed in a detachable shaft bearing, the second end of forme mandrel roller is installed on a bearing block, the second end hollow of forme mandrel roller is also communicated with a valve, is provided with mandrel roller gravity centre adjustment mechanism outside described bearing block.
Further, described mandrel roller gravity centre adjustment mechanism comprises eccentric shaft, eccentric shaft holder, hand lever and torque arm, described eccentric shaft fixed seating is below the second end of forme mandrel roller and be fixedly installed on bearing block, described eccentric shaft is installed on eccentric shaft holder, the first end of described torque arm is sleeved on eccentric shaft, the second end of torque arm offers adjustment hole, described adjustment hole is sheathed on the second end of forme mandrel roller, leave adjusting play between the second end of adjustment hole and forme mandrel roller, described hand lever is fixedly installed on eccentric shaft.
Further, described detachable shaft bearing comprises the bearing seat of honour and bearing base, and described bearing base offers dovetail groove, and bottom, the described bearing seat of honour to be nested in dovetail groove and to be locked by connector.
The bearing block of forme mandrel roller first end is set to detachably by the utility model, forme mandrel roller the second end is fixed on bearing block, when forme will be changed, only need to dismantle the bearing block on forme mandrel roller first end, mandrel roller gravity centre adjustment mechanism is then utilized to make it keep barycentre steadiness to the second end force, do not drop, time saving and energy saving, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is flexographic printing forme drum structural representation described in the utility model embodiment;
The mandrel roller gravity centre adjustment mechanism structural representation that Fig. 2 is flexographic printing forme drum described in embodiment;
Fig. 3 is detachable shaft holder structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model preferred embodiment is described in detail.
As shown in Figure 1, a kind of flexographic printing forme drum, it plate sleeve 2 comprising forme mandrel roller 1 and be set in outside forme mandrel roller 1, the first end 11 of described forme mandrel roller is installed in a detachable shaft bearing 3, the second end 12 of forme mandrel roller is installed on bearing block 4, the second end 12 hollow of forme mandrel roller is also communicated with a valve 5, is provided with mandrel roller gravity centre adjustment mechanism 6 outside described bearing block 4.
As depicted in figs. 1 and 2, described mandrel roller gravity centre adjustment mechanism 6 comprises eccentric shaft 61, eccentric shaft holder 62, hand lever 63 and torque arm 64, be fixedly installed on bearing block 4 below the second end 12 that described eccentric shaft holder 62 is positioned at forme mandrel roller, described eccentric shaft 61 is installed on eccentric shaft holder 62, the first end 641 of described torque arm is sleeved on eccentric shaft 61, the second end 642 of torque arm offers adjustment hole 643, described adjustment hole 643 is sheathed on the second end 12 of forme mandrel roller, adjusting play H is left between the second end 12 of adjustment hole 643 and forme mandrel roller, described hand lever 63 is fixedly installed on eccentric shaft 61.
As shown in Figure 3, described detachable shaft bearing 3 to comprise at the bottom of the bearing seat of honour 31 and bearing 32, and described bearing base 32 offers dovetail groove 321, and the bottom 311 at the described bearing seat of honour to be nested in dovetail groove 321 and to be locked by connector 33.
When changing plate sleeve 2, pulling hand lever 63 makes eccentric shaft 61 deflect, eccentric shaft 61 drives torque arm 64 to hold forme mandrel roller 1 downwards, ensures the barycentre steadiness of forme mandrel roller, now unloads connector 33, the bearing seat of honour 31 is separated with bearing base 32, pass through valve 7 to forme mandrel roller 1 inner inflatable, under gas pressure, the internal diameter of plate sleeve 1 swells, and plate sleeve 2 will unclamp forme mandrel roller 1 simultaneously, so just can take off old plate sleeve 2 like a cork, then be inserted in new plate sleeve; New plate sleeve is inserted in rear stopping inflation completely, plate sleeve will hold forme mandrel roller 1 tightly, loads onto the bearing seat of honour 31 and locks, and oppositely pulls hand lever 63, forme mandrel roller 1 upwards pushes away by the stroke that adjustment hole 643 moves an adjusting play H, and plate sleeve 1 has been changed.
Mandrel roller gravity centre adjustment mechanism structure of the present utility model is not limited to the manual adjust structure shown in embodiment, also can prevent the tenesmus of mandrel roller first end for other, ensure the frame for movement of its steadily of centre of gravity, as pneumatic adjust structure etc., but described in embodiment, mandrel roller gravity centre adjustment mechanism structure is simple, compact and laborsaving; Connector between the bearing seat of honour and bearing base can be bolt, latching or the conventional removable connector of other mechanical fields.
