When the movable plate 42 moves downward, it drives the movable platform 47 at the bottom to move downward. When the movable platform 47 moves downward, it drives the top rod 48 and the knife seat 49 at the bottom to move downward. When the knife seat 49 moves downward, it drives the cutting knife 50 at the bottom to move downward. When the cutting knife 50 moves downward, it first contacts the plastic plate 9, thereby cutting the part where the formed workpiece is connected to the plastic plate 9 to prevent the workpiece from sticking to the plastic plate 9. When the top rod 48 contacts the workpiece, it applies downward pressure to the workpiece, so that the workpiece separates from the plastic plate 9 and falls into the receiving trough of the bottom receiving bin 44. The conical portion provided on the top of the receiving trough can prevent the workpiece from being deflected when falling.

[0030] A slide groove 52 is provided at the connection between the knife seat 49 and the cutting knife 50, a connection block 51 is fixedly provided at the connection between the top of the cutting knife 50 and the slide groove 52, and a spring 53 is connected between the bottom of the connection block 51 and the bottom of the slide groove 52. When the cutting knife 50 contacts the plastic plate 9, it is pushed upward, so that the connection block 51 and the slide groove 52 slide relative to each other. At this time, the spring 53 stretches, generating a downward pulling force on the cutting knife 50, so that the contact between the cutting knife 50 and the plastic plate 9 remains stable, reducing the vibration between the cutting knife 50 and the plastic plate 9, and avoiding defects such as burrs on the edge of the workpiece.

[0031] Working principle: During the blister processing, the transmission chain 4 drives the plastic plate 9 to move to the inside of the blister section 2. At this time, the transmission chain 4 stops moving, and the cylinder 10 is started, so that the push rod 20 at the bottom of the cylinder 10 moves downward, driving the upper slide 21 at the bottom of the push rod 20 to move downward along the vertical rod 19. When the upper slide 21 moves downward, it drives the upper slide 22 to move downward. When the upper slide 21 moves downward, it drives the upper slide 16 on the upper part of the two-way threaded rod 14 to move downward. When the upper slide 16 moves downward, it drives the two-way threaded rod 14 threadedly connected thereto to start rotating, so that the lower slide 15 threadedly connected to the bottom of the two-way threaded rod 14 moves toward the upper slide 16. When the lower slide 15 moves, it drives the lower slide 29 at the bottom of the vertical rod 19 upward When the lower slide plate 29 moves upward, it drives the lower slide table 30 at the top and the upper slide table 22 to move toward each other, so that the blister groove 32 and the sealing groove 31 at the top of the lower slide table 30 move upward accordingly. When the upper slide table 22 moves downward, it drives the movable mold 26 and the sealing strip 27 at the bottom to move downward. Through the cooperation between the movable mold 26 and the mold groove at the bottom of the blister groove 32, the plastic plate 9 between the upper slide table 22 and the lower slide table 30 can be formed. Through the cooperation of the sealing strip 27 and the sealing groove 31, the gap between the blister groove 32 and the movable mold 26 can be sealed, so that the plastic plate 9 is more closely attached to the bottom of the blister groove 32 during molding, thereby realizing high-precision blister molding of the plastic plate 9 and improving the molding quality.

[0032] When the lower slide plate 29 moves upward, it drives the connecting rod 38 connected to its outer side to move upward. When the connecting rod 38 moves upward, it drives the rack 18 connected to it to move upward, so that the rotating joint 37 engaged with it through the fixed latch 40 rotates to a state where the positive pressure joint is upward when the rack 18 moves upward. At this time, the upper chamber on the upper part of the diverter tube 36 is connected with the positive pressure joint, so that the upper connecting pipe 25 generates positive pressure. At this time, the airflow flows into the upper diverter chamber 23 along the upper air inlet pipe through the upper air inlet joint 24, and then flows into the upper diverter chamber 23 through the upper diverter chamber 23, and finally flows out along the spray hole at the bottom of the movable mold 26. During molding, a downward thrust is applied to the top of the plastic plate 9, and the lower chamber is connected with the negative pressure joint, so that the lower connecting pipe 35 generates negative pressure, so that the interior of the lower diverter chamber 33 generates negative pressure through the lower air inlet pipe and the lower air inlet joint 34. The bottom hole of the bottom of the blister groove 32 is pressurized, thereby generating negative pressure on the bottom hole of the bottom of the blister groove 32, generating downward suction on the bottom of the plastic plate 9, thereby applying downward pressure to both sides of the plastic plate 9 during the blister process, so that the plastic plate 9 and the bottom of the blister groove 32 fit more closely. When the blister is completed, the lower slide plate 29 starts to move downward, and the rack 18 moves downward accordingly, thereby driving the rotating joint 37 to start rotating in the opposite direction, so that the positive pressure joint rotates to a downward state. At this time, the upper chamber on the upper part of the diverter cylinder 36 is connected with the negative pressure joint, so that the upper connecting pipe 25 generates negative pressure, and the lower chamber is connected with the positive pressure joint, so that the lower connecting pipe 35 generates positive pressure, so that when the plastic plate 9 is separated from the blister groove 32, upward pressure is applied to both sides of the plastic plate 9 simultaneously, so as to avoid adhesion between the plastic plate 9 and the blister groove 32, which affects the quality of the workpiece.

[0033] When the upper slide plate 21 moves downward, it drives the left movable block 28 to move downward, so that the cross bar 12 connected thereto moves downward. When the cross bar 12 moves downward, it drives the right movable block 39 at the right end to move downward, so that the movable plate 42 moves downward. When the movable plate 42 moves downward, it drives the movable platform 47 at the bottom to move downward. When the movable platform 47 moves downward, it drives the top rod 48 and the knife seat 49 at the bottom to move downward. When the knife seat 49 moves downward, it drives the cutting knife 50 at the bottom to move downward. When the cutting knife 50 moves downward, it first contacts the plastic plate 9, thereby cutting the part connected to the plastic plate 9 after the workpiece is formed, so as to prevent the workpiece from contacting the plastic plate 9. The material plate 9 is adhered. When the push rod 48 contacts the workpiece, downward pressure is applied to the workpiece, so that the workpiece is separated from the plastic plate 9 and falls into the receiving trough of the bottom receiving bin 44. The conical portion provided on the top of the receiving trough can prevent the workpiece from being deflected when falling; when the cutting knife 50 contacts the plastic plate 9, it is pushed upward, causing the connecting block 51 and the slide groove 52 to slide relative to each other. At this time, the spring 53 is stretched, and a downward pulling force is exerted on the cutting knife 50, so that the contact between the cutting knife 50 and the plastic plate 9 remains stable, reducing the vibration between the cutting knife 50 and the plastic plate 9, and avoiding defects such as burrs on the edges of the workpiece. The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
