[0023] This utility model provides a punching device for feeding blister trays.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The system includes a machine base 1, a top plate 2 on top of the machine base 1, and fixed posts 3 at the four corners of the bottom of the top plate 2. Multiple fixed posts 3 are fixedly connected to the machine base 1. A pallet mold 5 is located on the top of the machine base 1. A hopper 4 is located inside the machine base 1. A hopper door 6 is installed on the front of the machine base 1. The pallet mold 5 passes through the top of the machine base 1 and extends into the hopper 4. The pallet mold 5 is fixedly connected to the machine base 1. An air extraction structure is located on one side of the pallet mold 5. A mounting plate 7 is located on the top of the pallet mold 5. Two first hydraulic rods 9 are fixedly connected to the top of the mounting plate 7. The top ends of the two first hydraulic rods 9 penetrate the top plate 2 and are fixedly connected to the top plate 2. The two first hydraulic rods 9 are symmetrically distributed relative to the vertical center line of the top plate 2. Two connecting blocks 14 are fixedly connected to both sides of the mounting plate 7. Sliding posts 11 are slidably connected to the inner sides of multiple connecting blocks 14. The two ends of the sliding posts 11 are respectively connected to the top plate 2 and the machine base 1. The platform 1 is fixedly connected, and a heating plate 8 is installed at the bottom of the mounting plate 7. The bottom of the mounting plate 7 is provided with a fixing component. Mounting brackets 22 are provided on both sides of the mounting plate 7. An adjustment component is provided between the two mounting brackets 22. Two punching cutters 24 are installed at the bottom of the two mounting brackets 22. Two U-shaped rods 18 are fixedly connected to both sides of the mounting plate 7. The bottom ends of multiple U-shaped rods 18 pass through the top of the platform 1 and extend into the material bin 4. Multiple U-shaped rods 18 are slidably connected to the platform 1. Multiple discharge holes 15 are opened at the bottom of the inside of the pallet mold 5. I-shaped plates 16 are fixedly connected between multiple U-shaped rods 18. I-shaped plates 16 are set inside the material bin 4. Multiple circular blocks 17 are fixedly connected to the top of the I-shaped plates 16. The circular blocks 17 are set inside the discharge holes 15. A sealing gasket is fitted on the outside of the circular blocks 17. The sealing gasket is in contact with the pallet mold 5 and the I-shaped plates 16.

[0025] The air extraction structure includes an air pipe 100 and a vacuum pump 101. The air pipe 100 is located on one side of the tray mold 5 and is fixedly connected to the tray mold 5. The vacuum pump 101 is fixedly connected to one side of the machine base 1, and the air pipe 100 is installed at the suction end of the vacuum pump 101.

[0026] Specifically, the workpiece to be processed is placed on the pallet mold 5 and fixed by a fixing component (the fixing component will be further explained later). Then, the two first hydraulic rods 9 are activated to move the mounting plate 7 downward. The mounting plate 7 moves the heating plate 8 downward. At the same time, the mounting plate 7 moves the I-shaped plate 16 downward through multiple U-shaped rods 18, so that multiple circular blocks 17 are moved away from multiple discharge holes 15. Meanwhile, the heating plate 8 can heat and soften the workpiece to be processed. Then, the two first hydraulic rods 9 are activated again to reset the mounting plate 7. Multiple circular blocks 17 are inserted into the multiple discharge holes 15. The sealing gaskets fitted on the outside of the circular blocks 17 achieve a sealing effect. The vacuum pump 101 is activated, and the air pipe 100 extracts the gas inside the top plate 2 to complete the processing.

[0027] After the formed tray cools down, the relative positions of the two mounting brackets 22 can be adjusted by adjusting the settings of the components (which will be further explained later). This allows the multiple punching blades 24 to be positioned relative to the multiple discharge holes 15. Then, the two first hydraulic rods 9 are activated, and the mounting plate 7 drives the multiple U-shaped rods 18 and the two mounting brackets 22 downwards. The multiple U-shaped rods 18 drive the multiple circular blocks 17 away from the discharge holes 15 through the I-shaped plate 16, while the multiple punching blades 24 can complete the punching work. The waste material after punching is discharged into the hopper 4 through the discharge holes 15 for collection. Therefore, this structural design eliminates the need for personnel to move the tray to the punching equipment for processing, improving the practicality of the device.

[0028] Please see Figure 1 , Figure 2 and Figure 3 The fixing component includes a clamping frame 10, which is located at the bottom of the mounting plate 7. Connecting plates 12 are fixedly connected to both sides of the clamping frame 10. Second hydraulic rods 13 are fixedly connected to the top of the two connecting plates 12. The two second hydraulic rods 13 are fixedly connected to the bottom of the top plate 2. Two connecting plates 12 are slidably connected to two sliding columns 11, and the other two connecting plates 12 are slidably connected to the other two sliding columns 11. A sealing gasket is provided at the bottom of the clamping frame 10, and the sealing gasket is installed on the top of the tray mold 5.

[0029] Specifically, the two second hydraulic rods 13 drive the two connecting plates 12 to move downwards. The two connecting plates 12 slide on multiple sliding columns 11 respectively. The connecting plates 12 can press the workpiece to be processed onto the pallet mold 5. With the help of the sealing gasket, the pallet mold 5 and the workpiece to be processed are tightly connected to facilitate the processing of the workpiece.

[0030] Please see Figure 3 and Figure 4 Each of the two mounting brackets 22 has a limiting block 25 on one side of its opposite side. The limiting block 25 is in contact with the mounting bracket 22, and both limiting blocks 25 are fixedly connected to the bottom of the top plate 2.

[0031] The adjustment assembly includes a bidirectional screw 19 and two square rods 23. The bidirectional screw 19 is located on the top of the mounting plate 7. Both ends of the bidirectional screw 19 are rotatably connected to support seats, and both support seats are fixedly connected to the mounting plate 7. Both mounting brackets 22 are threadedly connected to the two ends of the bidirectional screw 19. A worm gear 20 is fixedly connected to the middle of the bidirectional screw 19. A worm 21 is meshed with the outside of the worm gear 20. A support block is rotatably connected to the outside of the worm 21. A throttle handle is fixedly connected to one end of the worm 21. Both square rods 23 are fixedly connected to the top of the mounting plate 7. Both ends of the square rods 23 pass through the two mounting brackets 22 and are slidably connected to the two mounting brackets 22. Both ends of the square rods 23 are fixedly connected to stop blocks.

[0032] Specifically, when the throttle is turned, the worm 21 meshes with the worm wheel 20, and the worm wheel 20 drives the bidirectional screw 19 to rotate. The bidirectional screw 19 is threadedly connected to two mounting brackets 22, and the two mounting brackets 22 slide on two square rods 23. When the two mounting brackets 22 are adjusted in opposite directions and the two mounting brackets 22 contact the two limit blocks 25 respectively, the throttle can be stopped. Therefore, it can be ensured that multiple punching cutter bodies 24 can correspond to multiple discharge holes 15 for punching.
