The present invention relates to a printer, specifically relates to a spiral spline phase adjusting device of a printer, and belongs to the technical field of printer equipment. The spiral spline phase adjusting device comprises a circumferential adjustment driving mechanism, a circumferential adjustment lead screw, an inner spiral spline, an outer spiral spline and a plate roller; a driving terminal of the circumferential adjustment driving mechanism is connected with the circumferential adjustment lead screw, and the circumferential adjustment lead screw is in threaded connection with a front connecting base; a front end of the front connecting base is connected with a front gland, and a front end of the front gland is connected with a rear connecting base; and the rear connecting base is connected with a rear gland via a bearing, an inner side of the rear gland is provided with the inner spiral spline, and the inner spiral spline is engaged with the outer spiral spline disposed on the steel roller. The spiral spline phase adjusting device is simple, compact and reasonable in structure, the outer spiral spline drives the steel roller to rotate so as to achieve circumferential adjustment, implementation cost is low, adjustment precision is accurate, and presswork production quality is improved.
Description
technical field [0001] The invention relates to a printing machine, in particular to a helical spline phase adjustment device for a printing machine, which belongs to the technical field of printing machine equipment. Background technique [0002] In the prior art, the circumferential adjustment device of the printing machine is realized through the axial movement of the helical gear on the plate roller relative to the external gear, and the power is transmitted from the plate gear to the external gear, which then drives the plate cylinder to rotate. So as to achieve the purpose of circumferential adjustment. In the prior art, the circumferential adjustment device of the printing machine has a complex structure, high implementation cost, low adjustment accuracy, and low quality of printed products produced. [0003] In order to achieve the same purpose of circumferential overprinting, the present invention provides a phase adjustment device with reasonable structure, low ...
