Embodiment Construction

[0010] Refer to the attached drawings, a film-receiving structure for film digital printing, including a number of side-by-side high-low staggered pre-tightening adjusting seats 1, film-retracting wheel 2, and the film-receiving wheel 2 is coaxially provided with a code plate 3, film-receiving wheel 2 Driven by a motor, the film 4 passes through the pre-tightening wheels 5 of several pre-tightening adjusting seats 1 in turn, and the film collecting wheel 2 is wound to collect the film 4. A code bar 6 and an arc-shaped code pin are arranged above the film collecting wheel 2 7. The outer wall of the arc-shaped code needle 7 is pressed on the film of the film-retracting wheel 2. The pre-tightening adjusting seat 1 includes a square adjusting seat 8. The upper end of the adjusting seat 8 is equipped with a pre-tightening wheel 5, and the lower part of the adjusting seat 8 is provided with a groove. The slot 9 is provided with a driving gear 10 driven by a motor, and two sides of the...

Abstract

The invention discloses a film take-up structure for digital film printing, which is characterized by comprising a plurality of pre-tightening adjusting seats and a film take-up wheel, wherein the pre-tightening adjusting seats are arranged side by side and up and down alternately; an encoding disc is coaxial with the film take-up wheel; the film take-up wheel is driven by a motor; a film passes through pre-tightening wheels of the pre-tightening adjusting seats in sequence and is taken up by the film take-up wheel; an encoding bar and an arc-shaped encoding needle are arranged above the film take-up wheel; and the outer wall of the arc-shaped encoding needle presses against the film on the film take-up wheel. The film take-up structure for digital film printing can meet the film take-up requirements of different thicknesses and can perform real-time monitoring and control treatment of the film take-up thickness and the film pre-tightening during a film take-up process of a digital printer.

Description

Technical field [0001] The invention relates to the field of film printing, in particular to a film receiving structure for film digital printing. Background technique [0002] Digital printing is a printing technology that has developed rapidly in recent years. It uses a method of directly transmitting, processing, and printing data. That is, the imaging data is input once, and the imaging component is controlled by the control system to directly image. For the commonly used drop-on-demand digital printing equipment, the imaging component is under the control of the control system. When the surface of the substrate such as paper reaches a predetermined position, the piezoelectric crystal in the nozzle generates pulses to squeeze the ink out and directly Spray mist ink droplets to the surface of the substrate such as paper for imaging. . [0003] A major problem faced by the existing printer technology is that the real-time monitoring and control of the film thickness and film p...
