The electric telescopic rod 6 will drive the horizontal plate 7 to move downward. The horizontal plate 7 will drive the linkage plate 8 to move downward. The linkage plate 8 will drive the triangular plate 9 to move downward. Then the packaging box inside the hopper 5 will fall onto the material guiding plate 13. The ejector rod 10 will squeeze the left end of the material guiding plate 13 to move downward, and then conduct the packaging box. After the packaging box falls onto the conveyor belt 1, control the telescopic movement of the electric telescopic rod 6 to drive the horizontal plate 7 and the linkage rod to move. The linkage rod will drive the triangular plate 9 to move, so as to achieve the effect of moving the hopper 5 upward, and the effect of blocking the hopper 5 can be achieved. Repeating the above operations can achieve the effect of uniform feeding;

[0024] In an embodiment: A rubber plate 14 is fixedly installed on the outer wall of the material guide plate 13. Torsion springs 15 are fixedly welded to both ends of the rotating shaft 12. Support plates 16 are fixedly welded to the outer walls of the two stabilizing plates 11. Baffle plates 17 are fixedly installed inside the two fixing frames 2;

[0025] Specifically, a rubber plate 14 is provided outside the material guide plate 13, which can achieve the effect of guiding out the packaging box.

[0033] Specifically, the ejector rods 10 are symmetrically arranged on both sides of the hopper 5, which can better and more stably squeeze the material guide plate 13 to achieve the effect of squeezing and moving the material guide plate 13 downward. Since the width between the two guide rods is greater than the width of the hopper 5, the packaging box will not be stuck between the two ejector rods 10;
