In other embodiments, the paper feeding structure may also be a robot to grasp the substrate 20 onto the carrying surface 121 by the robot. Optionally, an air suction roller may be added to the rear end of the substrate 20 to decelerate the substrate 20, so as to reduce the advancing speed of the substrate 20 and prevent the substrate 20 from flying out of the carrying surface 121.

When the substrate 20 is removed from the carrying surface 121, the transfer wheel 131 moves upward, so that the fixed magnetic assembly 12 starts to fix the magnetic force to the next substrate 20, and so on.
Further, the paper feeding assembly 13 further includes a shaft 132 and a fourth driving member (not shown), the transmission wheel 131 is fixed on the shaft 132, the fourth driving member is connected to the shaft 132 and is used for driving the shaft 132 to move up and down, after the fixed magnetic assembly 12 completes the magnetic field application to the printing material 20, the fourth driving member driving shaft 132 moves down to drive the transmission wheel 131 to descend, so that the transmission wheel 131 abuts against the printing material 20, and then the transmission wheel 131 is driven to rotate, so that the printing material 20 is moved out of the carrying surface 121 by friction force.
In this embodiment, the moving path of the transmission wheel 131 is a straight path moving up and down, and in other embodiments, the moving path of the transmission wheel 131 may also be an arc path.
In this embodiment, the shaft 132 is provided with two spaced conveying wheels 131, and when the object 20 is conveyed, the two conveying wheels 131 respectively abut against both ends of the object 20, so that the force applied to the object 20 is more uniform.
Further, the distance between two adjacent conveying wheels 131 can be adjusted, so that the conveying wheels 131 can adapt to the printing materials 20 with different sizes, and the applicability of the paper feeding assembly 13 is improved.
In other embodiments, only 1 transfer wheel 131 or 3 transfer wheels 131 may be provided on the shaft 132, and the selection may be specifically made according to the size of the substrate 20, and is not specifically limited herein.
In the above embodiment, the positioning, the magnetism fixing and the paper feeding of the printing stock 20 are all completed at the same station, so that the integration level is high, the volume of the device can be reduced, and the printing efficiency is improved.
