Description

TECHNICAL FIELD

[0001] The utility model relates to the improvement of straight-out digital printing machine, especially to the improvement of straight-out digital printing machine of movable splicing spray head. BACKGROUND

[0002] Straight-out digital printing machine is favored by customers due to fast speed and high efficiency, but the expensive price becomes the biggest problem of the promotion of this machine type. If the printing width of normal machine is wider, the corresponding width of the spray head is equipped, and the spray head is the most expensive accessory on the machine, and the spray head is fixedly arranged and cannot be moved and adjusted. In the carton industry, most of the printing contents are discontinuous in width, at this time, part of the spray head does not ink, and the width of the ink actually needed is much narrower than the width of the paper, so that part of the spray head cannot be utilized, and the position cannot be adjusted to meet the printing demand of wider printing width.

[0004] In order to solve the above technical problem, the utility model is realized by adopting the following technical scheme: the straight-out digital printing machine with movable splicing spray heads comprises a printing platform, a fixed cross beam arranged on the printing platform and a plurality of spray head modules arranged on the fixed cross beam, characterized in that: a lifting cross beam is movably arranged on the front side of the fixed cross beam, a horizontal guide rail is arranged on the front side of the lifting cross beam, and the plurality of spray head modules are movably arranged on the horizontal guide rail, and the corresponding plurality of spray head modules can be separated or combined according to the printing requirement.

[0005] The opposite sides of two adjacent spray head modules are provided with step surfaces that are spliced with each other.

[0006] The cross section of the spray head module is Z-shaped.

[0007] The spray head module is provided with an electromagnet, and the spliced spray head modules are magnetically positioned.

[0008] The lifting guide rail and the lifting motor thereof are arranged between the fixed cross beam and the lifting cross beam.

[0009] The lifting guide rail is divided into two symmetrical lifting guide rails, and the lifting motor is arranged in the middle of the fixed cross beam.

[0010] The front side of the lifting cross beam is provided with a synchronous belt, and the spray head module is provided with a synchronous wheel and a driving motor, and the synchronous wheel is in transmission engagement with the synchronous belt.

[0011] The horizontal guide rails are symmetrically arranged in upper and lower two parts, and the synchronous belt is arranged between the two horizontal guide rails.

[0012] The improved straight-out digital printing machine with movable and spliced spray heads divides the spray head modules into multiple groups, each group can move on the cross beam, can be seamlessly spliced with each other, can also be pulled apart, realizes that there is a spray head module at the position with ink spraying and there is no spray head module at the position without ink spraying, and enables the relatively small number of spray head modules to adapt to wider printing width.

[0016] The drawings show the structure of the utility model, and the related details will be further explained below with reference to the drawings. Figs. 1-2 The straight-out digital printing machine with movable and spliced spray heads comprises a printing platform 1, a fixed cross beam 2 arranged on the printing platform 1 and a plurality of spray head modules 4 arranged on the fixed cross beam 2, a lifting cross beam 3 is movably arranged on the front side of the fixed cross beam 2, a horizontal guide rail 7 is arranged on the front side of the lifting cross beam 3, and the plurality of spray head modules 4 are movably arranged on the horizontal guide rail 7, and the corresponding plurality of spray head modules 4 can be separated or combined with each other according to printing requirements.

[0017] The working principle of the utility model is that the lifting cross beam 3 moves up and down on the front side of the fixed cross beam 2 to adjust and drive the plurality of spray head modules 4 to lift as a whole to adapt to different thicknesses of printed matter, then the spray head modules 4 can be manually or electrically driven to move along the horizontal guide rail 7, so each spray head module 4 can be moved individually and can be lifted uniformly, the adjacent spray head modules 4 can be seamlessly spliced or pulled apart, the position with ink spraying has a spray head module 4, the position without ink spraying has no spray head module 4, and the relatively small number of spray head modules 4 can adapt to the printing requirements of wider paper width.
