Abstract

The invention discloses a film unwinding structure for digital film printing. The film unwinding structure comprises a plurality of side-by-side pre-tightening adjusting seats which are arranged in a high-low staggered mode, a printing platform and a code wheel. Press rolls are arranged on the printing platform. Each pre-tightening adjusting seat comprises a square adjusting seat body, the upper end of the adjusting seat body is provided with a pre-tightening wheel, a notch is formed in the lower portion of the adjusting seat body, a driving gear is arranged in the notch, and the two sides of the notch are provided with racks engaged with the driving gear. The code wheel is arranged coaxial with a film unwinding wheel which is driven by a motor. A film is wound around the film unwinding wheel. The film unwinding structure can meet the requirements for printing films of different thicknesses and controls the feed speed and tightness degree of the films through a sensor to achieve the purpose of automation control.

Description

technical field [0001] The invention relates to the field of thin film printing, in particular to a film releasing structure for digital printing of thin films. Background technique [0002] Digital printing is a printing technology that has developed rapidly in recent years. It adopts the method of directly transmitting, processing and printing data. That is to say, the imaging data is input once, and the imaging component is directly imaged by the control system. For the commonly used digital printing equipment of on-demand inkjet printing, 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 a pulse to squeeze out the ink, and directly Spray mist ink droplets on the surface of the substrate such as paper to form an image. [0003] One of the main problems faced by the existing printer technology is that the real-time monitoring...
