Description

Technical Field

[0001] The present application relates to the technical field of product labeling, and in particular to a cam labeling mechanism. Background Art

[0002] With the continuous development of industrial production and the increasing variety of products, higher requirements are placed on the accuracy and completeness of product information. Labels, as an effective information carrier, can clearly display various specifications of products, so that consumers and producers can quickly understand the basic situation of the products and make correct purchasing and use decisions.

[0003] The prior art discloses a precision labeling head mechanism, including a support frame, on which a suction and breaking integrated valve, an upper and lower driving module, a rotating module and a plurality of suction nozzle modules are installed. The suction nozzle module includes an air rod, a synchronous pulley and a suction nozzle. One end of the air rod is connected to the suction and breaking integrated valve, and the other end is connected to the suction nozzle. The synchronous pulley is sleeved on the air rod. The upper and lower driving modules are connected to the suction nozzle module and the upper and lower driving modules can drive the suction nozzle module to move up and down. The rotating module is connected to the synchronous pulley and the rotating module drives the suction nozzle to rotate through the synchronous pulley. When working, the suction nozzle absorbs the label under the control of the suction and breaking integrated valve, and then moves to the vicinity of the product to be labeled under the drive of the external driving mechanism. Then, the labeling position of the product is obtained through the suction nozzle module, and the rotating module is controlled to operate according to the information obtained, so that the angle of the label on the suction nozzle is adjusted to match the labeling position, and then the suction nozzle module is driven downward to accurately fit the label on the product. Finally, the suction and breaking integrated valve is de-vacuumed to control the suction nozzle to release the label, and the entire labeling operation is completed.

[0004] Regarding the above-mentioned related technologies, since the nozzle module is connected to the rotating module through a synchronous pulley, and the synchronous pulley is prone to uneven wear during long-term use, the rotating module may get stuck or have uneven rotation speed when driving the nozzle to rotate, resulting in missed or excessive labeling, affecting the labeling efficiency of the product.
