Description

Technical Field

[0001] The utility model relates to the technical field of lunch box processing, in particular to a magnetic adsorption structure for trimming the edges of lunch boxes. Background Technique

[0002] With the continuous improvement of people's requirements for the quality of lunch boxes, the technology of trimming the edges of lunch boxes is also constantly developing and improving. Trimming the edges of lunch boxes is an important link in the production process of lunch boxes, which involves the trimming and shaping of the edges of lunch boxes to ensure that the lunch boxes meet specific size and shape requirements. In order to improve the processing efficiency of the edge trimming link, a magnetic adsorption structure is usually used to improve the feeding speed of lunch boxes.

[0003] Most of the existing magnetic adsorption structures for trimming the edges of lunch boxes use fixed electromagnetic chucks to adsorb lunch boxes for moving and feeding operations. However, the size of this electromagnetic chuck is fixed. When it is necessary to feed larger or smaller lunch boxes, the electromagnetic chuck cannot be adjusted, resulting in too small a contact area between the chuck and the lunch box, which may lead to unstable adsorption. Furthermore, when moving the lunch box, it may fall off, which may cause harm to surrounding personnel or other equipment. Therefore, we propose a magnetic adsorption structure for trimming the edges of lunch boxes to solve the problems mentioned above. Content of the Utility Model
