A rotary press for printing

Abstract

The invention discloses a rotary machine for printing, the structure of which comprises a paper reel, a paper feeder, a controller, a printing machine, an indentation and creasing line cutting machine, a paper reel, a paper reeling platform, a base, and a paper reel. There is a paper feeder, a base is set on the side of the paper feeder, a printing machine is installed on the base, a controller is connected to the left side of the base, an indentation crimping cutting machine is connected to the right side of the base, and a paper receiver is set on the right side of the base. There is a delivery platform on the side of the paper machine. The printing machine includes a printing cylinder gear, a transmission gear, and a detection device. The printing cylinder gear meshes with the transmission gear on the side. The detection device is respectively connected to the printing cylinder gear and the transmission gear. The beneficial effects of the present invention are: judging whether there is a gap between the printing cylinder gear and the transmission gear by whether the two rollers touch the touch sensor at the same time, and reminding the staff in time when a problem is found, reducing unnecessary losses and improving printing quality.

Description

Technical field[0001]The invention relates to the field of rotary printing presses, in particular to a rotary press for printing.Background technique[0002]The rotary die-cutting machine continuously rotates in the form of a hob. It is one of the most efficient equipment in the die-cutting machine. Die-cutting products are widely used in mobile phones, computers, liquid crystal displays, digital cameras, LCD backlights and other fields.[0003]Because the printing speed of the rotary machine is very high, after a period of work, the printing cylinder gear will wear out, resulting in a larger gap with the transmission gear, so that the cylinder gear cannot roll according to the meshing line, and there will be a slight difference between the transmission gear The printing speed will cause the printing image and text part to produce an ink ribbon equal to the pitch of the gear at this sliding moment, which will reduce the printing quality. It needs frequent inspection and maintenance duri...

AI Technical Summary

Problems solved by technology

[0003] Due to the high printing speed of the rotary machine, after a period of work, the printing cylinder gear will be worn, resulting in a larger gap with the transmission gear, so that the cylinder gear cannot roll according to the meshing line, and there will be a slight difference between the printing cylinder gear and the transmission gear. speed, it will cause the printed graphic part to produce an ink ribbon equal to the pitch of the gear at the moment of sliding, which will reduce the printing quality. It needs to be inspected and maintained frequently during use, and it cannot be found at the first time. After the delay, the printed things may be scrapped and improved. Cost of production
