Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 3 and Fig. 4, the clearance adjustment mechanism of printing machine up-down rollers of the present utility model, comprise top roll 1, lower roll 2, be arranged on respectively for a pair top roll two ends spindle nose and install correspondingly top chock 3 in the groove of the groove neutralization operation facing-wall board of driving face wallboard, be arranged on lower roll for a pair respectively two ends spindle nose and the step 4 installed correspondingly in the groove of the groove neutralization operation facing-wall board of driving face wallboard 20 and the pressure screw mandrel 5 being connected to the upper surface of a pair top chock 3 for a pair correspondingly, wherein:
The upper skewback 71 that a lower surface is inclined-plane is fixed by screw in the lower surface of a pair top chock 3; Upper skewback 71 is arranged on by flat key 73 on the lower surface of top chock 3;
The lower skewback 72 that a upper surface is inclined-plane is installed by a flat key 74 in the upper surface of a pair step 4, and the gradient of the upper surface of this lower skewback 72 is identical with the gradient of the lower surface of upper skewback 71;
Upper skewback 71 and lower skewback 72 form the middle cushion block 7 in gap of adjusting upper roll 1, lower roll 2;
The corresponding front and rear end being positioned at the lower skewback 72 of driving face wallboard 20, front and rear end of driving face wallboard 20 horizontally offers a fine thread hole respectively, a fine thread hole is horizontally offered in the corresponding front and rear end being positioned at the lower skewback 72 of operating surface wallboard, front and rear end of operating surface wallboard, all install an adjustment screw mandrel 8,8 ' in each fine thread hole, the head of these two adjustment screw mandrels 8,8 ' withstands on the front and rear end of lower skewback 72 respectively;
A pair pressure screw mandrel 5 is connected to the upper surface of a pair top chock 3 correspondingly by the nut block of the upper surface of the nut block 50 and operating surface wallboard that are fixed on the upper surface of driving face wallboard 20.
The control method of the clearance adjustment mechanism of printing machine up-down rollers of the present utility model is: because upper skewback 71 can not be moved on top chock 3 by flat key 73 screw fastening; Step 4 is also installed a flat key 74, lower skewback 72 is installed on flat key 74, and lower skewback 72 can realize moving forward and backward under the location of flat key 74.During adjustment, first unscrewing pressure screw mandrel 5, top chock 3 is not stressed the restriction of screw mandrel 5, adjustment screw mandrel 8 ' on rear side of turning clockwise again, be rotated counterclockwise the adjustment screw mandrel 8 of front side simultaneously, by lower skewback 72 forward, the gradient of the gradient of the lower surface of skewback 71 and the upper surface of lower skewback 72 in utilization, in increase cushion block 7 height and top chock 3 is lifted, the gap of top roll 1 and lower roll 2 is increased, otherwise, the adjustment screw mandrel 8 of the front side that turns clockwise, be rotated counterclockwise the adjustment screw mandrel 8 ' of rear side simultaneously, the gap of top roll 1 and lower roll 2 is reduced.When being adjusted to suitable gap, and the tight nut 80 regulated on screw mandrel 8, just can complete gap adjustment.
The adjustment screw mandrel 8 that the clearance adjustment mechanism of printing machine up-down rollers of the present utility model is selected revolves and turns around, and the gap of top roll 1 and lower roll 2 is changed to 0.02mm, and therefore degree of regulation is higher.
The clearance adjustment mechanism of printing machine up-down rollers of the present utility model, adopt upper and lower skewback as middle cushion block, and the forward and backward side of lower skewback connect respectively an adjustment screw mandrel change in the height of cushion block, realize the gap change of upper and lower roll, therefore laborsaving, convenient, can realize fine setting, and without the need to installing and removing any parts, security is high.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
