Embodiment Construction
[0029] The label rewinding method of the present invention adopts a rotating shaft that drives the label to rotate, a transmission device that transmits power to the rotating shaft in the form of friction torque, and a power device for driving the transmission device to rotate. The label rewinding method includes the following: step:
[0030] A1) The power unit starts to drive the transmission unit to rotate;
[0031] A2) The transmission device drives the rotating shaft to rotate through the friction torque, and the rotating shaft drives the label to rotate;
[0032] The friction torque can be adjusted. The friction torque can be adjusted and changed by the maximum static friction force between the transmission device and the power device.
[0033] In step A2, the design rotational speed of the transmission device is greater than the rotational speed required by the rotating shaft to recover the label, and synchronization is achieved through frictional slipping. The extern...

The invention relates to a label wrapping device and the method. The device comprises turning-shaft module for turning printed label into coil. The turning-shaft module comprises turning shaft, sleeve tube, motor, frictional piece and pulley. The pulley applies axial pressure to the frictional piece by pressing-tightly device. The motor drives the pulley rotate and form frictional torque with the frictional piece. The pulley drives the frictional piece by the frictional torque rotate as the turning shaft rotates. When the frictional torque is smaller than load relative movement between the pulley and the frictional piece can be generated. The method comprises following steps. A1) power device is started to drive the transmission device rotate. A2) the transmission device drives the turning shaft rotate by the frictional torque and the turning shaft drives label wrap around. A3) the frictional torque can be adjusted. Because the label wrapping device the method in invention can guarantee the wrapping speed is the same with the output speed of printer completely and the wrapping device is in rotating status all the time so that the wrapping effect is better and there is no need of larger field in using process.
Description
technical field [0001] The present invention relates to paper rolling equipment, and more particularly, to a label rewinding device. Background technique [0002] The label roll capacity of a label printer is usually tens of meters to hundreds of meters long. When printing in batches, it is necessary to use a rewinder or manually roll up the printed labels in time to avoid label damage caused by scattering. The rewinding speed generated by the reel driven by the motor of the rewinder cannot be completely consistent with the output speed of the printer, so there must be a corresponding device on the rewinder to ensure that the rewinding speed of the rewinder is synchronized with the output speed of the printer. The way to achieve synchronization in the prior art is to install a photoelectric or electromechanical sensor in the paper path area between the rewinder and the printer. state, when the paper output by the printer 19 accumulates to a certain amount, the paper 18 fall...
