When cutting the blister box, the blister box to be cut can be placed on the top of the blister machine platform plate 1, and cutting knives 46 are installed on the top and bottom of the mounting roller 43. When it rises upward after completing the cutting downward, the gear 47 engages with the rack 491 to realize the flipping of the mounting roller 43, thereby achieving the purpose of alternating cutting of the two cutting knives 46, which can effectively avoid the situation where a single cutting knife 46 may affect the service life of the cutting knife 46 when performing cutting work for a long time.

[0036] A first limiting rod 497 is fixedly connected to the rear side of the positioning plate 492, and the first limiting rod 497 penetrates the rear side wall of the second U-shaped plate 48. A guide plate is fixedly connected to the inner side of the main body plate 3, and the guide plate penetrates the connecting plate 42. The first limiting rod 497 can provide a limit for the positioning plate 492. A socket 498 is provided on the rotating shaft 45, and a plug plate 499 is provided on the top of the socket 498. The plug plate 499 matches the socket 498.

[0038] The cutting mechanism 4 includes a mounting assembly, which includes two mounting plates 485, which are fixedly connected to the two cutting knives 46 respectively. Mounting grooves are provided at the top and bottom of the mounting roller 43. The two mounting plates 485 are placed inside the two mounting grooves respectively, and the mounting plates 485 match the mounting grooves. One end of the mounting roller 43 is rotatably connected to a threaded rod 486, and one end of the threaded rod 486 is rotatably connected to the inner side of the T-shaped plate 44. The mounting roller 43 can be inserted and installed inside the mounting groove. A control panel is fixedly connected to the outside of the threaded rod 486. A fixing plate 487 is arranged outside the threaded rod 486. The threaded rod 486 penetrates a side wall of the fixing plate 487 and is threadedly connected to the fixing plate 487. The bottom of the fixing plate 487 contacts the inner side of the T-shaped plate 44. The fixing plate 487 extends into the inside of the mounting groove. The fixing plate 487 extends into the inside of the mounting plate 485. After the threaded rod 486 rotates, it can drive the fixing plate 487 to move horizontally.

[0039] In actual operation, when the device is used, the device is first powered on. When working, the blister box to be cut can be placed on the top of the blister machine platform plate 1. After the second electric push rod 494 works, it can push the first U-shaped plate 41 up and down. It can be seen from the above connection relationship that when the first U-shaped plate 41 moves downward, the cutting knife 46 at the bottom can cut the blister box. After the downward cutting is completed, it rises upward and the gear 47 passes the position of the rack 491. The gear 47 engages with the rack 491 to cause the gear 47 to rotate. After the gear 47 rotates, it drives the rotating shaft 45 to rotate, and the rotating shaft 45 drives the installation roller 43 to rotate. The installation roller 43 drives the installation plate 485 to rotate, and the installation plate 485 drives the cutting knife 46 to flip. When it passes the rack 491 and the first U-shaped plate 41 touches the press switch When the gear 47 moves to the bottom of the rack 491, the first electric push rod 493 completes the retraction and stretching, thereby prompting the rack 491 to move back to a position where it can mesh with the gear 47, thereby facilitating the next flipping and replacement of the cutting blade 46, thereby achieving the purpose of the two cutting blades 46 taking turns to perform the cutting task, thereby avoiding the situation where a single cutting blade 46 needs to work for a long time and bear a large workload;

[0040] In the present device, the electromagnetic block 481 is electrically connected to the second electric push rod 494. When the second electric push rod 494 pulls the first U-shaped plate 41 upward, the electromagnetic block 481 is energized and adsorbs the metal block 482. At this time, the plug plate 499 stays above the insertion hole 498 and does not hinder the rotation of the installation roller 43. When the second electric push rod 494 is extended after the cutting knife 46 is replaced, the electromagnetic block 481 is powered off. Due to the influence of gravity and the elastic force of the spring, the plug plate 499 can be quickly inserted into the insertion hole 498, thereby The rotating shaft 45 is limited. It can be known from the above connection relationship that the stability of the cutting knife 46 during cutting can be guaranteed at this time. Finally, if the cutting knife 46 needs to be replaced or maintained, it is only necessary to rotate the control panel, and the control panel drives the threaded rod 486 to rotate. The threaded rod 486 drives the fixing plate 487 to move away from the inside of the mounting plate 485. At this time, the mounting plate 485 can be directly taken out from the mounting roller 43, and the purpose of quick disassembly is achieved accordingly, which is conducive to the user to quickly perform maintenance or replacement of the cutting knife 46, and is more flexible to use.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
