As a key piece of equipment in a packaging production line, the core task of a cartoning machine is to rapidly form flat box blanks and complete product filling and sealing.
A typical process path is as follows: The cardboard box blank in the hopper is sucked in by a suction cup and simultaneously pushed by a cylinder to open the box. Then, the left and right auxiliary rocker levers at the bottom of the box fold the auxiliary rocker levers, and the tongue mechanism simultaneously folds into the bottom and top tongues. The bottom capping mechanism then presses shut to seal the bottom. After the feeding pusher accurately pushes the tea bag into the formed cardboard box, the top auxiliary rocker lever folds the top auxiliary rocker levers, and the top capping mechanism finally presses shut to seal the box. The finished product is continuously output.
The entire action chain requires extremely high precision and consistent response. The stability of the suction cup force, the matching of the cylinder stroke and thrust, the timing of the lever and tongue actions, the uniformity of the capping pressure, and the pusher's positioning all directly affect the success rate of opening, the accuracy of filling, and the quality of sealing.
For these moving parts and positioning components, precision machining can be performed on a single piece or in small batches according to the design drawings provided by the customer. This ensures that key components fully match the original machine requirements in terms of materials, tolerances, and surface treatment, thereby guaranteeing the long-term stable operation of the entire machine. From unpacking to final output, each station collaborates to complete a full packaging cycle. Understanding and optimizing the mechanical details in this process is fundamental to improving packing efficiency and reliability.
