Description

Technical Field

[0001] The invention relates to the technical field of a prefabricated bag storage mechanism for a packaging machine, in particular to a bag storage bin and a bag taking mechanism. Background Art

[0002] The prefabricated bag storage mechanism of the packaging machine is a device used to store and manage prefabricated packaging bags to ensure a continuous and stable supply of packaging bags during the packaging process. This mechanism supports the efficient operation of the packaging machine by storing, sorting, conveying and monitoring packaging bags. The bag storage mechanism usually includes a storage area, a conveying device, a sorting device and a control system. The storage area is used to store a certain number of prefabricated packaging bags. The conveying device transports the packaging bags from the storage area to the bag-taking position. The sorting device ensures that the packaging bags are neatly arranged. The control system monitors the number and status of the storage bags through sensors to ensure the smooth progress of the packaging process.

[0003] The existing prefabricated bag storage mechanism of the packaging machine adopts a horizontal bag storage and flat laying design. This design method has many problems in actual use.

Secondly, the structure of the bag storage mechanism is relatively complex, including multiple mechanical parts and motion devices, which requires a lot of time and effort to debug and adjust when changing different types of packaging bags, affecting the continuity and production efficiency of the production line. In addition, the existing touch screen operation interface design is not intuitive and convenient enough. Operators need to repeatedly search and confirm multiple options when setting and adjusting the bag storage parameters, which is prone to errors and cumbersome to operate.

At this time, the main machine sucks the bag away and proceeds to the next step.

[0014] The present invention provides a bag storage bin and a bag taking mechanism, which have the following beneficial effects: The present invention provides a bag storage bin and a bag taking mechanism. The present invention changes the traditional horizontal bag bin into a vertical bag bin by adopting a mechanical transmission method combining a servo motor with a synchronous belt, a connecting rod and a negative pressure belt conveyor, thereby greatly saving space, optimizing the workshop layout, and overcoming the problem that the existing horizontal bag storage mechanism occupies a large amount of space and restricts the layout of the entire machine. In addition, the bag bin is placed at the sealing position, so that the bag taking mechanism can take the bags quickly and accurately, thereby improving the bag taking speed and efficiency, and reducing the time loss caused by bag taking delays in the production process. At the same time, the design of the connecting rod mechanism enables the bags to remain stable during the conveying process, avoids position deviation of the bags during the conveying process, ensures the accurate positioning of the bags, thereby improving the overall production efficiency and product quality.
