In actual use, a quick-change device is required to complete the disassembly and assembly of the mold and the vacuum forming machine. In actual use, it has the advantages of stable structure, safe use, and good connection effect.

[0003] The prior art discloses a blister mold that is easy to install on a blister machine, with application number CN201821856252.4. In this utility model, the mold needs to be placed inside the mounting block for installation, and then four plug-in structures are needed to connect the mold to the mounting block. The four pull-out operations are cumbersome, and there is a gap between the mold and the inner wall of the mounting block, making it difficult for operators to fine-tune the mold position inside the mounting block, which reduces the practicality of this utility model. At the same time, there is no cleaning structure before the mold is connected, but when impurities are adsorbed on the mold surface, the plug-in structures press against the impurities, which may cause the impurities to damage the plug-in structures or the mold surface, thus posing a hidden danger to the continued use of this utility model.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0015] (1) This utility model adopts clamping plates, insert plates and slots. When using the quick change device for the mold of the blister packaging machine, the mold can be placed inside the bottom box. When multiple sets of balls contact the lower part of the mold, the mold can be moved. During this process, multiple sets of balls are subjected to friction and roll inside multiple sets of ball sockets. When one side of the mold contacts the inner wall of the bottom box, the operator rotates the handwheel by hand. The handwheel can drive the bidirectional screw lever to rotate. Since the bidirectional screw lever and the two sets of screw sleeves are threaded together, the rotating bidirectional screw lever can push the two sets of screw sleeves to move or move away from each other. The two sets of screw sleeves can drive the two sets of insert plates to move closer to each other through the two sets of clamping plates. When the two sets of insert plates are inserted into the two sets of slots respectively, the mold installation is completed. The guide rod plays the role of guiding the two sets of clamping plates. Through the clamping plates, insert plates and slots, the mold connection can be completed in a labor-saving and convenient manner, which improves the practicality of the quick change device for the mold of the blister packaging machine.

[0016] (2) This utility model adopts a through groove and a collection box. According to the above operation, the mold can move inside the bottom box. Before that, the operator moves the two sets of mounting screws in opposite directions by hand. When the gap length between the two sets of brush plates reaches the appropriate value, the two sets of mounting screws and the four sets of mounting nuts are engaged with each other by thread. The operator rotates the four sets of mounting nuts clockwise and counterclockwise by hand. When the four sets of mounting nuts are in close contact with the bottom box, the two sets of brush plates are stably fixed. At this time, the mold can be placed on multiple sets of support rollers. Then the mold can be moved. During this process, the bristles of the two sets of brush plates can scrape and wipe away the impurities adsorbed on the surface of the mold. The fallen impurities will fall into the inside of the collection box. After cleaning, the mold can be connected. Pulling the pull plate can remove the collection box to clean the impurities. Through the through groove and collection box, the cleaning structure is provided, which can clean the impurities adsorbed on the surface of the mold, and provide a guarantee for the continuous use of the quick change device for the mold of the vacuum forming machine.

At the same time, according to the above... As can be seen from the operation, the mold 6 can move inside the base box 1. Before this, the operator moves the two sets of mounting screws 16 in opposite directions by hand. When the gap length between the two sets of brush plates 17 reaches the appropriate value, the two sets of mounting screws 16 and the four sets of mounting nuts 18 are engaged with each other by thread. The operator rotates the four sets of mounting nuts 18 clockwise and counterclockwise by hand. When the four sets of mounting nuts 18 are in close contact with the base box 1, the two sets of brush plates 17 are stably fixed. At this time, the mold 6 can be placed on the multiple sets of support rollers 15. Then the mold 6 can be moved. During this process, the bristles of the two sets of brush plates 17 can scrape and wipe away the impurities adsorbed on the surface of the mold 6. The detached impurities will fall into the inside of the collection box 3. After cleaning, the mold 6 can be connected. Pulling out the pull plate 19 can remove the collection box 3 to clean the impurities. Through the set through groove 2 and collection box 3, a cleaning structure is provided to clean the impurities adsorbed on the surface of the mold 6, which ensures the continuous use of the quick change device for the blister packaging machine mold.
