In practice, the suction cup design requires a pipeline to be connected to external negative pressure equipment.

When the label is sucked by the label suction head in operation, the spring is contracted upwards to absorb the excessive stroke of the label suction head and the label, so that the label is protected. The slide rail plays a guiding role to ensure the straightness of the suction mark head; when the label contacts with the sucker, the sucker forms a vacuum airtight environment with the contact surface of the label through negative pressure, so that the label is sucked. After the label is sucked, the suction head moves upwards, and the spring recovers to be long. When the label is pasted on the label suction head, the spring is contracted upwards to absorb the excessive stroke of the label suction head and the label pasting object, so that the effect of protecting the label pasting object is achieved, and meanwhile, the spring applies pressure to the label pasting object, so that the label pasting strength and flexibility are improved. The sliding rail plays a guiding role to ensure the straightness of the label suction head, when the label is contacted with the labeling object, the sucking disc breaks vacuum through positive pressure, the label is released to be adhered to the labeling object, and finally the labeling action is completed.

The utility model also provides a labelling machine comprising a flexible suction head as described above.

The flexible labeling machine consists of a linear rail structure with a guiding function, a spring buffer structure for providing flexibility and a suction head mechanism with flexibility and adsorption performance. After the printer outputs the label, the label suction head firstly sucks the label, and the sucking disc and the label form a vacuum airtight environment through negative pressure so as to suck the label; when the label is successfully absorbed, the label absorbing head is used for labeling, the label absorbing head is fully contacted with a labeling object during labeling, the spring is contracted to play a buffering role, and meanwhile, the attaching force and the flexibility of the label absorbing head are improved. And after the labeling is finished, the positive pressure is communicated with the label suction head, the vacuum is broken between the suction nozzle and the label, and the label suction head leaves the labeling object. The suction mark head adopts the design that the spring buffer mechanism is matched with sliding, so that the functions of flexible suction mark and labeling are realized, the potential safety hazard of a rigid structure is reduced, and compared with the existing scheme, the suction mark head has larger labeling force and enhances the attaching capability.

It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the utility model and is not intended to limit the utility model, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the utility model are intended to be included within the scope of the utility model.
