Bevel drying device used for online switching between screen printing and offset printing and based on offset printing platform

Abstract

The invention discloses a bevel drying device used for online switching between screen printing and offset printing and based on an offset printing platform. The bevel drying device is provided with ascreen printing device and an offset printing device, and quick switching can be achieved; through pressing of a button corresponding to the offset printing mechanism, single offset printing is performed; when single screen printing is required, through pressing of a button corresponding to the screen printing mechanism, single screen printing is performed; through pressing of a button corresponding to a drying mechanism, screen printing and offset printing are performed; the arranged drying mechanism can be used for timely drying after printing of the offset printing mechanism, and damage tooffset printing patterns during screen printing is avoided; a heating lamp box, a bottom drying shell and a serpentine heating pipe are arranged in the bevel drying device, so that the drying temperature in the drying device shell is increased quickly; the drying efficiency is improved greatly; an outer convex and circular arc lamp cover is arranged, so that heat radiation rays of an UV lamp arediffused; thus, the heat radiation rays can be irradiated on printing paper uniformly, and the drying speed is increased greatly; and the drying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to an offset printing platform-based screen printing offset printing online switch and a slope drying device. Background technique [0002] Offset bill printing requires silk screen printing, but traditional printing devices do not have silk screen printing devices. Therefore, in the form printing equipment and industrial processing, silk screen and drying platforms are used in the middle of the original form printing machine to solve the process requirements. However, this method not only has a long construction period, but also costs a lot, which in turn leads to increased production costs. The existing patent number is 201906805488, which discloses an online switching of screen printing offset printing and its slope drying device based on an offset printing platform, including offset printing. Platform and printing paper, the offset printing platform is composed of the...

[0002] Offset bill printing requires silk screen printing, but traditional printing devices do not have silk screen printing devices. Therefore, in the form printing equipment and industrial processing, silk screen and drying platforms are used in the middle of the original form printing machine to solve the process requirements. However, this method not only has a long construction period, but also costs a lot, which in turn leads to increased production costs. The existing patent number is 201906805488, which discloses an online switching of screen printing offset printing and its slope drying device based on an offset printing platform, including offset printing. Platform and printing paper, the offset printing platform is composed of the first offset printing unit, the second offset printing unit and the third offset printing unit which are connected front and back. It also includes the screen printing head, which is connected to the support plate, and the positioning paper guide roller is used to adjust the tension of the printing paper and the offset printing silk screen online The switching adjustment module and the drying module used to accelerate the curing ink; the drying module forms a slope with a certain angle with the plane of the offset printing platform under the support of the adjustment module; the invention has a simple structure and can print without destroying the overall structure of the original form. The ability to realize offset printing and silk screen printing, however, the screen printing and offset printing devices of this invention cannot be switched flexibly. When printing, they all need to go through the silk screen printing and offset printing devices in turn, and single offset printing or single silk screen printing cannot be performed, which greatly improves the applicability of the equipment. reduced, and cannot be effectively promoted. At the same time, the existing drying module only uses uv lamps for drying, and the drying efficiency is low, resulting in a reduction in printing efficiency and greatly increasing production costs. The emergence of a printing device with a drying device that performs switching and has a high drying efficiency is imminent
