Abstract
Description
[Technical field]
[0001] The utility model relates to an adjustment technology for an ink fountain in a printing press, in particular to an adjustment device for an ink fountain in packaging printing. [Background technology]
[0002] In the printing industry, inking, as the starting link of the printing press, plays a key role in the quality of printed products. The accuracy of ink fountain adjustment is related to the accuracy of ink application, which in turn affects the quality of printed products.
[0003] Traditional ink fountain adjustment is generally done manually, by manually adjusting the ink fountain screw on the ink fountain. The ink fountain screw is adjusted by holding the ink fountain blade to change the gap between the ink fountain blade and the ink roller. On the one hand, this adjustment method mainly relies on the experience of the workers to judge the adjustment amount, and it is difficult to accurately adjust the ink amount; on the other hand, this adjustment method is slow, and the ink fountain screws need to be tightened one by one during adjustment, which is very time-consuming. For example, a traditional full-open four-color printing press has more than 120 ink fountain screws, and it takes a long time to adjust once, resulting in a longer preparation time for printing, affecting the efficiency of the printing press and wasting a lot of unnecessary resources. [Utility Model Content]
[0004] The utility model provides an adjustment device for an ink fountain in packaging printing, which can perform offline debugging on an ink fountain replaced on a printing press, thereby ensuring production conditions, avoiding occupation of production resources, effectively saving debugging time, and improving the production efficiency of the printing press.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] An adjusting device for an ink fountain in packaging printing, used for offline debugging of a printing ink fountain, comprises a base platform and a marking ink fountain roller for offline debugging of the printing ink fountain;
[0007] Two symmetrically arranged vertical plate seats are installed on both sides of the table top along the length direction for horizontally installing the ink fountain roller in the axial direction, and the inner sides of the vertical plate seats are also respectively installed with bearing seats for supporting the circumferential rotation of the ink fountain roller when the ink fountain is adjusted in different areas;
[0008] The printing ink fountain comprises an ink fountain body and a plurality of ink supply blocks, and arc-shaped double-section elastic self-locking claws are respectively installed at both ends of the ink fountain body adjacent to the inner side of the vertical plate seat, and the entire ink fountain body is clamped axially against the marking ink fountain roller through a self-tensioning spring;
[0009] A plurality of ink supply blocks are evenly installed in a row at the lower rear side of the ink fountain body, with the front ends extending into the inner cavity of the ink fountain body and axially contacting the marking ink fountain roller respectively. The rear end of each ink supply block is provided with an ink supply knob for adjusting the gap between the corresponding ink supply block and the marking ink fountain roller to change the amount of ink supplied in the area.
[0010] Preferably, a power driving unit for driving the marking ink fountain roller to rotate is coaxially mounted on the vertical plate seat on one side of the base platform.
[0011] Preferably, the vertical plate seat is an inverted T-shaped support structure.
[0012] Preferably, the top of the arc-shaped double-section elastic self-locking claw is also equipped with a follower wheel that contacts and rotates synchronously with the marking ink fountain roller. Preferably, both ends of the self-tensioning tension spring on the arc-shaped double-section elastic self-locking claw are respectively connected with a pin structure that facilitates joint linkage.
[0013] The beneficial effects of the utility model are:
[0014] When the printing ink fountain in packaging printing needs to be replaced and debugged, it is replaced with a spare printing ink fountain. Then, the printing ink fountain that needs to be debugged is clamped on the two ends of the marking ink fountain roller for offline debugging through the arc-shaped double-section elastic self-locking claws at both ends of the ink fountain body and the elastic self-tensioning cantilever. While the marking ink fountain roller is driven to rotate by the power drive unit, the ink supply knob at the rear end of each ink supply block is rotated and debugged in a partitioned manner, and the gap between each ink supply block and the marking ink fountain roller is adjusted separately to change the ink supply amount in the area, so that the ink supply amounts in adjacent areas do not affect each other and the ink supply is uniform, which effectively improves the debugging efficiency, reduces production costs, reduces the labor intensity of workers, and improves production efficiency.
