working principle:

In specific implementation, the radius size of the label roll being unloaded can be monitored by the radius sensor 89, which can be installed on the second mounting substrate 39 to connect the radius sensor to the controller signal. When it is detected that the radius size of the label roll being unloaded is smaller than the threshold, it means that the label roll needs to be replaced. At this time, the controller controls the cylinder 54 to extend, and drives the tape splicing roller 17 to press the tape on the outer surface of the spare roll to complete the bonding of the tape (the outer surface of the spare roll is pasted with double-sided tape). The meshing of the ratchet 43 and the pawl 45 is to prevent the turntable 13 from being reversed under the pressing action of the splicing roller 17 and causing the failure of splicing. Then, the controller controls the second stepping motor 51 to drive the blade 16 to move from top to bottom to longitudinally cut off the remaining tape currently being used. Subsequently, the controller controls the first stepping motor 42 to drive the turntable 13 to rotate 180° counterclockwise, Place the new label roll in its original position and continue labelling.

When labeling the conical flask, first adjust the inclination angle of the labeling head by adjusting the mechanism 6 .

The support plate 77 and the pressure plate 78 of the elastic platen assembly are connected by an elastic member, and the spring 80 of the elastic member gives a certain buffering distance to the pressure plate 78, so as to avoid the unsuitable adjustment of the distance between the pressure plate 78 and the belt 70, resulting in insufficient extrusion force and the existence of the label attached. Problems such as bubbles and unevenness improve the labeling quality of the labeling machine.
