Multi-azimuth front-and-back-overprinting digital printing machine electronic eye device

Abstract

The invention relates to a multi-azimuth front-and-back-overprinting digital printing machine electronic eye device. The device comprises a left positioning sliding block, a fixing shaft and a right positioning sliding block, and the left positioning sliding block and the right positioning sliding block are arranged on the fixing shaft in a sleeved mode through corresponding through holes respectively. The left positioning sliding block is installed on a printer through a groove. The upper end face of the right positioning sliding block is provided with an electronic eye containing hole. The electronic eye position of the right positioning sliding block coincides with the position of a mark label by moving the fixing shaft, and the left positioning sliding block and the right positioning sliding block are fastened on the fixing shaft through jackscrews after the electronic eye position of the right positioning sliding block coincides with the position of a mark label. Due to the fact that an external electronic eye is adopted, the electronic eye can rotate by 360 degrees on the fixing shaft, and therefore secondary registration printing of non-transparent materials can be achieved. Meanwhile, product material waste and defective products caused due to the fact that a primary registration position is adjusted are reduced, therefore, the defect of limitation of digital printing equipment is overcome, and the requirements for application ranges and product innovation of printing products are met.

Description

technical field [0001] The invention relates to supporting parts of a digital printing machine, in particular to an electronic eye device for a multi-directional front and back overprinting digital printing machine. Background technique [0002] With the wide application of digital printing technology, more and more products require more distinctive printing. Due to the limitations of existing digital printing equipment in front and back overprint printing, the electronic eye is fixed at one position, the movement range is limited, and it can only recognize the non-printed surface mark, and the second registration printing cannot be realized. Therefore, it restricts The application range of printing products and the demand for product innovation. Contents of the invention [0003] In view of the defects existing in the existing digital printing equipment, the present invention provides an improvement plan for the limitation of the electronic eye of the HP digital printing...
