Description

Technical Field

[0001] The utility model relates to the field of prefabricated dishes, and particularly relates to an automatic deviation rectification device for a boxed sealing machine. Background Art

[0002] Prefabricated dishes, also known as semi-finished dishes or convenient dishes, are dishes that have been pre-processed in a food processing factory, including steps such as cutting, cooking, and packaging. After consumers purchase them, they only need to be simply heated or cooked to be edible.

[0003] When boxed prefabricated dishes are packaged, a boxed sealing machine is used. During the use of the existing boxed sealing machine, when the sealing position is offset or skewed, workers need to stop the machine to adjust the sealing bag, which is time-consuming and laborious and not very convenient. Therefore, technical personnel in this field have provided an automatic deviation rectification device for a boxed sealing machine to solve the problems raised in the above background art.
