Description

TECHNICAL FIELD

[0001] The utility model relates to automatic packaging equipment technical field, especially in automatic cartoning machine's feeding mechanism. BACKGROUND

[0002] The automatic cartoning machine is the key equipment in modern packaging flow line, and its core function is to efficiently and accurately pack the material into the packaging box. The feeding mechanism, as an important part of the cartoning machine, directly determines the stability of material conveying and the efficiency of cartoning. In the existing design of the feeding mechanism, the push head, as an executive element, usually adopts a horizontal reciprocating linear motion to complete the pushing action of the material. The working process is as follows: when the material is transported to the designated station by the conveying belt, the push head extends horizontally to push the material into the packaging box, and then returns to the initial position for the next pushing action. However, in actual application, the material conveying belt is usually equipped with multiple groups of continuously moving baffles for separating and positioning the material. Although this design ensures the sequential conveying of the material, it also puts strict space avoidance requirements on the reset action of the push head. Specifically, when the push head completes the pushing and needs to reset, if it directly returns horizontally along the original path, its motion trajectory will interfere with the continuously moving baffles on the conveying belt, causing equipment jamming or even damage. To avoid this problem, the existing technology usually adopts a step-by-step action control strategy, that is, the push head needs to perform a vertical lifting action during the reset process to move out of the height range of the baffles, and then perform a horizontal return action. This process involves the sequential control of two independent driving mechanisms (such as the lifting module and horizontal motion module driven by a gas cylinder or motor), resulting in a prolonged reset cycle of the push head, complex action connection, and thus limiting the overall efficiency improvement of the cartoning machine. Therefore, there is an urgent need for a new type of feeding mechanism that can realize the linkage of push head return and lifting action. SUMMARY
