Problems solved by technology

However, due to the continuous increase of the diameter of the web on the rewinding expansion shaft, it is difficult to control the motor speed and torque, resulting in a large fluctuation range of the tension force, and the paper cannot be completely tightened. However, Navier code printing is high-precision printing. The printed ink line is nano-scale, and the paper needs to be completely taut, otherwise the printed Navier code will not be recognized, and the existing printing equipment cannot meet the requirements

Abstract

The invention relates to a printing device, in particular to a nano-dimensional web printing and feeding device. The nano-dimensional code web printing and feeding device comprises a discharge expansion shaft and a receiving expansion shaft and further comprises a frame, a discharge motor, a receiving motor and a printing tensioning device. A printing platform is arranged on the frame. The discharge expansion shaft and the receiving expansion shaft are both mounted on the frame and correspondingly located on both sides of the printing platform. The discharge motor is fixed to the frame, and the discharge motor is connected to one end of the discharge expansion shaft. The receiving motor is fixed on the frame, and one end of the receiving expansion shaft is connected with the receiving motor. The printing tensioning device is mounted on one side of the printing platform and located between the printing platform and the discharge expansion shaft. The nano-dimensional web printing and feeding device has the beneficial effects of simple structure, effective control over the printing tension of webs, stable tensioning of the webs during the printing process and reliable printing qualityof the nano-dimensional code.

Description

Technical field [0001] The invention relates to a printing device, in particular to a Navier code roll paper printing and feeding device. Background technique [0002] The existing roll paper printing uses the rotation of the unwinding expansion shaft and the rewinding expansion shaft to realize paper feeding during the printing process. The unwinding expansion shaft is usually connected with a magnetic powder brake, and the rewinding expansion shaft is connected with a motor. The motor drives the rewinding expansion shaft to rotate to realize the rewinding. The magnetic powder brake on the unwinding expansion shaft provides tension to realize the tensioning of the roll during printing. paper. However, due to the continuous increase in the diameter of the roll paper on the rewinding expansion shaft, it is difficult to control the motor speed and torque, resulting in a large fluctuation range of the tension force and the paper cannot be fully tensioned. The Navitas printing is hi...
