Abstract

The invention discloses a pneumatic ejection-type shafted gravure installing mechanism of an intaglio printing machine. The pneumatic ejection-type shafted gravure installing mechanism of the intaglio printing machine comprises a gravure regulating device (1), a speed reducing gearbox (8), a gravure roll (7), and short cone heads (3) which are fixed on main shafts of the gravure regulating device (1) and the speed reducing gearbox (8) respectively, and further comprises a shaft roll (4), wherein the gravure roll (7) is a hollow roll; the shaft roll (4) is inserted into the gravure roll (7); the gravure roll (7) and the shaft roll (4) are fixed coaxially; conical heads with keys are arranged at two ends of the shaft roll (4); the conical heads are in tight fit with conical holes, which are provided with key grooves, on the short cone heads (3). Due to arrangement of the independent shaft roll, ejecting shaft heads on two sides of the printing machine are required to eject the shaft roll, and an elongated cone head is not required, so that in the process of using a narrow gravure roll for printing, enough rigidity can be ensured, the rigidity does not decrease even though the intaglio printing machine runs for a long time, the fluctuation of the tension is reduced, and the printing quality is ensured.

Description

The intaglio press air pushed has the axle plate lock-up mechanism
Technical field
The present invention relates to a kind of printing machine, particularly a kind of intaglio press air pushed has the axle plate lock-up mechanism.
Background technology
In the intaglio press printing process, top-plate axis need to bear larger pressure.When using the wide cut steel roller printing, because the top-plate axis that plate-regulating device and reduction box stretch out is shorter, the arm of force is short, and under larger squeegee pressure, the rigidity of top-plate axis also is enough to guarantee.But when using in a narrow margin steel roller printing, need to use to lengthen conehead, because the arm of force is long, under larger squeegee pressure, operation can make the rigidity that lengthens conehead descend for a long time, and rigidity decline can cause tension fluctuation in printing process to become greatly, affects printing quality.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and also can guarantee that the intaglio press air pushed of enough rigidity has the axle plate lock-up mechanism when using in a narrow margin steel roller printing.
The present invention addresses the above problem adopted technical scheme: a kind of intaglio press air pushed has the axle plate lock-up mechanism, comprise plate-regulating device, reduction box, printing plate cylinder and be separately fixed at plate-regulating device and the main shaft of reduction box on short conehead, it also comprises roll shaft; Described printing plate cylinder is hollow roll, and the roll shaft sleeve is in printing plate cylinder, and printing plate cylinder and roll shaft coaxial line are fixed; Described roll shaft two ends are provided with the conical head with key, the tight fit of the bellmouth with keyway on described conical head and short conehead.
Described printing plate cylinder and roll shaft coaxial line fixedly refer to, described printing plate cylinder two ends are provided with the tapered centre hole with keyway, the tapered centre hole of one end and first a conehead tight fit with key, the tapered centre hole of the other end and second a conehead tight fit with key, the second conehead also matches with a retaining ring, thereby described retaining ring is provided with the jackscrew that the second conehead and printing plate cylinder and the first conehead is held out against mutually for pushing up the second conehead, on described the second conehead, the position of corresponding jackscrew is provided with the perforate matched with jackscrew, described the first conehead, the centre bore of the second conehead and retaining ring all is linked on roll shaft and all is with to be useful on and prevents the clamping device be subjected to displacement with roll shaft.
Described clamping device comprise be opened in the first conehead, the second conehead with on the retaining ring circumference together with gap, gap one side is provided with the first screwed hole, the gap opposite side is provided with the counterbore corresponding with the first screwed hole, is combined with the bolt that can make the first conehead, the second conehead and retaining ring and roll shaft clamp in described the first screwed hole.
Described jackscrew screws in two the second screwed holes on being located at retaining ring, and two the second screwed holes are symmetrically distributed on retaining ring.
Compared with prior art, the invention has the advantages that: owing to having increased independently roll shaft, make holding out against spindle nose and only need holding out against roll shaft of printing machine both sides, lengthen conehead without using, can guarantee enough rigidity when using in a narrow margin steel roller printing, even long-play, rigidity can not descend yet yet, reduce tension fluctuation, guaranteed printing quality.

The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are further described.
As Figure 1-5, intaglio press air pushed of the present invention has the axle plate lock-up mechanism, comprise plate-regulating device 1, reduction box 8, printing plate cylinder 7 and be separately fixed at plate-regulating device 1 and the main shaft of reduction box 8 on short conehead 3, the axis of two short coneheads 3 is on same straight line, plate-regulating device 1 and reduction box 8 are arranged on frame, and it also comprises roll shaft 4; Described printing plate cylinder 7 is hollow roll, and roll shaft 4 sleeves are in printing plate cylinder 7, and printing plate cylinder 7 is fixed with roll shaft 4 coaxial lines, and printing plate cylinder 7 fixes and both coaxial lines with roll shaft 4; Described roll shaft 4 two ends are provided with the conical head with key, the tight fit of the bellmouth with keyway on described conical head and short conehead 3.
Described printing plate cylinder 7 fixedly refers to roll shaft 4 coaxial lines, described printing plate cylinder 7 two ends are provided with the tapered centre hole with keyway, the tapered centre hole of one end and first conehead 6 tight fits with key, the tapered centre hole of the other end and second conehead 9 tight fits with key, the second conehead 9 also matches with a retaining ring 5, thereby described retaining ring 5 is provided with the jackscrew that the second conehead 9 and printing plate cylinder 7 and the first conehead 6 is held out against mutually for pushing up the second conehead 9, described jackscrew screws in two the second screwed holes 11 on being located at retaining ring 5, two the second screwed holes 11 are symmetrically distributed on retaining ring 5, on described the second conehead 9, the position of corresponding jackscrew is provided with the perforate 12 matched with jackscrew, described the first conehead 6, the centre bore of the second conehead 9 and retaining ring 5 all is linked on roll shaft 4 and all is with to be useful on and prevents the clamping device be subjected to displacement with roll shaft 4.
