A plurality of evenly distributed positioning blocks 8 are welded in the carrier plate 2. A ejection assembly 9 is provided on the top of the carrier plate 2. The ejection assembly 9 includes a plurality of top plates 901. The plurality of top plates 901 are all arranged on the top of the carrier plate 2 and aligned one by one with the positioning blocks 8. Two sliding rods 902 are welded on the bottom of the plurality of top plates 901, and the sliding rods 902 pass through the positioning blocks 8. A limiting ring 903 is welded on the bottom end of the sliding rod 902. A spring 904 is sleeved on the outside of the sliding rod 902, and the two ends of the spring 904 are respectively connected to the top plate 901 and the positioning blocks 8. The positioning blocks 8 are fixed, and two hydraulic cylinders 3 are fixed on both sides of the shell 1 by bolts. One end of the hydraulic rods of the multiple hydraulic cylinders 3 is fixed with a movable plate 4 by bolts. Two sliding openings are provided on both sides of the shell 1, and the movable plate 4 moves along the sliding openings. A plurality of punching knives 5 are fixed to the bottom of the movable plate 4 by bolts. The multiple punching knives 5 are all rectangular. A plurality of internal elastic telescopic rods 6 are fixed to the bottom of the movable plate 4 by bolts. The multiple internal elastic telescopic rods 6 are respectively located in the multiple punching knives 5, and the multiple blister boxes formed as one piece are placed on the carrier plate 2, and the multiple blister boxes are respectively located above the multiple top plates 901 so that the top plates 901 The blister box is supported, and then the hydraulic cylinder 3 is started to extend and retract. The hydraulic cylinder 3 will drive the moving plate 4 to move downward along the slide, and the moving plate 4 will drive the punching knife 5 and the internal elastic telescopic rod 6 to move downward. The internal elastic telescopic rod 6 will contact the blister box during its downward movement. At this time, the moving plate 4 continues to move downward, so that the internal elastic telescopic rod 6 is squeezed and contracted, and at the same time, the top plate 901 is moved downward through the sliding rod 902. The top plate 901 will squeeze the spring 904, so that the blister box is clamped and fixed under the action of the internal elastic telescopic rod 6 and the top plate 901 squeezing the spring 904, avoiding the blister box When the punching is completed, the hydraulic cylinder 3 is started to extend, and the hydraulic cylinder 3 pushes the movable plate 4 to move upward along the slide, and the movable plate 4 drives the punching knife 5 and the internal elastic telescopic rod 6 to move upward. At this time, the internal elastic telescopic rod 6 will be restored by its own elastic force, and the top plate 901 will be reset by the force of the spring 904, thereby pushing the blister box out, so that the blister box cannot be stuck in the punching knife 5 and the positioning block 8, thereby facilitating the staff to take out the punched blister box, thereby improving the use effect of the punching mechanism.

[0027] The worm gear 12 is engaged with the worm gear 12 and the worm gear 12 is engaged with the worm gear 12, and the worm gear 12 is engaged with the worm gear 12.

[0028] In particular, the bottom of the movable plate 4 is located outside the blanking knife 5 and is fixed by bolts with two symmetrically distributed external elastic telescopic rods 7. When the blanking knife 5 punches the blister box, the external elastic telescopic rods 7 will squeeze the scraps of the blister box, thereby preventing the scraps of the blister box from moving. The upper surface of the carrying plate 2 is provided with a grid groove 10 for the blanking knife 5 to be inserted, and multiple positioning blocks 8 are all located in the grid groove 10. When the blanking knife 5 punches the blister box, the blanking knife 5 will enter the grid groove 10, so that the blanking knife 5 can better cut and divide the blister box. A discharge port is provided on the bottom of one side of the shell 1, and a side door 15 is hinged in the discharge port. A mounting groove is provided on one side of the shell 1, and a transparent plate 16 for observing the inside of the shell 1 is bonded in the mounting groove. An inclined plate 17 is welded to the bottom of the shell 1, and the inclined plate 17 is tilted downward toward the discharge port. The upper surface of the inclined plate 17 is flush with the bottom of the discharge port. After the blister box falls into the shell 1, the blister box will slide out of the shell 1 through the discharge port under the action of the inclined plate 17, thereby facilitating the removal of the blister box from the shell 1 and improving the convenience of removing the blister box.

[0029] The working principle of this embodiment is as follows: when in use, multiple blister boxes formed by integral blister molding are placed on the carrying plate 2, and the multiple blister boxes are respectively located above the multiple top plates 901 so that the top plates 901 support the blister boxes, and then the hydraulic cylinder 3 is started to extend and retract, and the hydraulic cylinder 3 will drive the movable plate 4 to move downward along the slide, and the movable plate 4 will drive the punching knife 5 and the internal elastic telescopic rod 6 to move downward, and the internal elastic telescopic rod 6 will contact the blister boxes during the downward movement, and at this time the movable plate 4 continues to move downward, so that the internal elastic telescopic rod 6 is squeezed and contracted, and at the same time, the top plate 901 is moved downward through the sliding rod 902, and the top plate 901 squeezes the spring 904, so that the blister boxes are squeezed by the action of the internal elastic telescopic rod 6 and the top plate 901 squeezing the spring 904. The clamping and fixing are performed to prevent the blister box from deflecting, and the punching knife 5 will continue to move downward, so that the punching knife 5 punches and cuts the blister box, and the punching knife 5 will enter the grid groove 10, so that the punching knife 5 can better cut and separate the blister box. When the punching is completed, the hydraulic cylinder 3 is started to extend, and the hydraulic cylinder 3 will push the movable plate 4 to move upward along the slide. The movable plate 4 will drive the punching knife 5 and the internal elastic telescopic rod 6 to move upward. At this time, the internal elastic telescopic rod 6 will restore by its own elastic force, and the top plate 901 will be reset by the force of the spring 904, thereby pushing the blister box out, so that the blister box cannot be stuck in the punching knife 5 and on the positioning block 8, which makes it convenient for the staff to take out the blister box after punching, thereby improving the use effect of the punching mechanism.
