The torsion spring makes one end of the limiting plate 26 extend out of the limiting groove 25 to block the substrate 2. The other end of the limiting plate 26 has a tail plate 28, and the bottom surface of the limiting groove 25 is provided with a stopper 29 for blocking the tail plate 28. The stopper 29 blocks the tail plate 28 to prevent the limiting plate 26 from flipping toward the side close to the substrate 2.

[0045] The blanking assembly includes a connecting frame 10 installed on the base plate 6, a telescopic rod rotatably connected to the connecting frame 10 via a rotating shaft, a driving unit for driving the rotating shaft to rotate, and a pressure head 15 installed at the end of the telescopic rod. A guide unit is also installed on the top plate 6, wherein the driving unit drives the telescopic rod to rotate, and the guide unit can change the length of the telescopic rod.

[0046] The driving unit includes a driven gear 11 mounted on the rotating shaft, a motor 8 mounted on the top plate 6 , and a driving gear 9 connected to the output shaft of the motor 8 , wherein the driving gear 9 and the driven gear 11 are meshed and connected.

[0050] The pressure head 15 has a conical structure and is made of soft rubber. The top end of the pressure head 15 is movably connected to the bottom end of the rod 1.

[0051] When the present device is in use, the substrate 2 is neatly arranged on the workbench, and the substrate 2 passes through the inkjet station, drying station, static station and unloading station in sequence to complete the printing of the substrate 2. During specific operation, when a substrate 2 reaches the unloading station, the unloading assembly works, and the motor drives the driving gear to rotate to rotate the telescopic rod. Due to the action of the guide unit, the length of the telescopic rod changes during the rotation. When the telescopic rod moves to vertical, the pressure head contacts the substrate 2 on the unloading station. When the telescopic rod continues to rotate, the telescopic rod continues to lengthen, which increases the static friction between the pressure head and the substrate 2. At this time, it can drive the substrate 2 to push the limit plate 26 to rotate, so that the substrate 2 finally passes the limit plate, and then the motor reverses to reset the telescopic rod, and the pushing mechanism pushes the substrate 2 on the workbench 1 forward a distance of the size of the substrate. This reciprocating process can achieve continuous unloading during printing and improve work efficiency.
