In order to fix the optical axis 103, the double-layered bag conveying deviation correcting device 10 may further include symmetrically disposed optical axis fixing wall plates 1031. The optical axis fixing wall plates 1031 may be respectively fixedly disposed on the modules adjacent to the double-bag conveying deviation correcting device 10, and the optical axis 103 is located between the two optical axis fixing wall plates 1031. Optionally, in order to enable the base 101 to slide on the optical axis 103 well, a sleeve 1032 is further sleeved on the optical axis 103, and the sleeve 1032 can be fixedly connected with the base 101, so that the base 101 can slide relative to the optical axis 103. Preferably, the number of the optical axes 103 may be at least two, the sleeves 1032 may be respectively disposed at two ends of the base 101 along the moving direction, and the number of the sleeves 1032 is four.

The adjusting screw 1021 is connected with the base 101, the adjusting screw 1021 can also rotate under the driving of the motor, and the screw 1021 can further drive the base 101 to move together. The motor may be located below the base 101. When the optical axes 103 are two, the lead screw 1021 may be located between the two optical axes 103. In other embodiments, the movement of the driving base 101 may be performed in many ways, for example, by using a cylinder, an electromagnetic drive, or a mechanical arm to move the base 101, and the present application is not limited to the embodiments, and the ways that can be conceived by those skilled in the art also belong to the scope of the present application.

In order to drive the movement of the bag body on the base 101, the double bag conveying deviation correcting device 10 further includes a conveying guide roller 104 and a driven guide roller 105.
