Description

Technical Field

[0001] The utility model relates to the technical field of empty bag detection, in particular to an empty bag detection device for green kidney bean dried fruits. Background Technique

[0002] The empty bag detection device for green kidney bean dried fruits is a device used to detect whether there are green kidney bean dried fruits in a packaging bag. This device usually uses an optical sensor or other sensing technologies to detect whether there is an object in the bag. If it is detected that the bag is empty (i.e., there are no green kidney bean dried fruits), an alarm or other processing measures will be triggered to ensure the integrity and quality of the packaging.

[0003] In the utility model patent published in the patent authorization announcement number CN217605020U, an empty bag detection device is disclosed, which includes: a frame, a connecting seat, a detection component, and a driving component. The connecting seat is movably arranged on the frame and can move up and down relative to the frame. The detection component is arranged on the connecting seat. The detection component includes an abutting member, an elastic member, and a detection sensor. The abutting member can move up and down relative to the connecting seat. The detection sensor is used to detect the position change of the abutting member. The elastic member is configured to provide a force to reset it downward when the abutting member moves upward. The driving component is connected to the connecting seat and is used to drive the connecting seat to act.
