Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, and more specifically to a cutting equipment for producing blister trays, which is convenient for replacing a cutting blade. Background Art

[0002] A blister tray refers to a plastic product with specific grooves made by the blister process. By placing the items to be placed in the grooves, it has a protective and beautifying effect. It is widely used in the food packaging industry. When producing blister trays, cutting equipment is required to cut the blister trays after blister forming. After long-term use, the cutting tools on the cutting equipment will inevitably be damaged and need to be replaced. The cutting tools on the cutting equipment for blister tray production in the prior art are mostly fixed by bolts. Although the fixation is relatively firm, auxiliary tools such as wrenches and screwdrivers are required for disassembly and assembly, which makes it inconvenient to replace the cutting tools and is time-consuming and labor-intensive.

[0003] The existing patent is a cutting device for producing blister trays that is easy to replace the cutter. The patent authorization number is CN219276031U. By rotating the adjusting rod, the adjusting block can slide and rise along the inside of the active cavity using the thread. Since the side of the adjusting block that abuts against the insertion rod adopts a slope structure, when the adjusting block gradually rises, the elastic spring will push the annular plate to slowly extend the insertion rod into the active cavity. During the process, the insertion rod will slowly detach from the inside of the socket, and then the tool can be removed from the inside of the installation port. The reverse operation can be performed during installation. The entire disassembly and assembly process does not require the use of auxiliary tools, which greatly improves the disassembly and assembly efficiency, thereby achieving the purpose of convenient replacement.

[0004] However, patent authorization number CN219276031U requires that the replaceable tool be installed inside the installation port and its two sides be flush with the two sides of the tool holder, and then the adjusting cap can be twisted in the opposite direction to rotate the adjusting rod in the opposite direction, so that the downward adjustment block is slowly inserted into the insertion hole against the insertion rod, thereby firmly limiting and fixing the position of the tool. Therefore, the steps in the assembly process are relatively cumbersome and there is room for improvement. Therefore, we propose a cutting device for blister tray production that is easy to replace the cutting knife to solve the above-mentioned problems. Utility Model Content

[0031] Example:

[0032] See also Figure 1-6 , a cutting device for producing blister trays that is easy to replace a cutting knife, comprising a workbench 1, a frame 2 fixedly connected to the upper surface of the workbench 1, a cylinder 3 installed on the top of the frame 2, and a knife holder 4 whose end is slidably connected to the frame 2 and whose top is connected to the movable end of the cylinder 3, the lower surface of the knife holder 4 is symmetrically provided with mounting holes 8, the inner side of the knife holder 4 is provided with a storage cavity 5 that is conductively connected to one of the mounting holes 8, a spring 6 is installed inside the storage cavity 5, the top of the knife holder 4 is provided with a guide hole 10 that is conductively connected to the storage cavity 5, and the guide hole 10 is arranged in a straight line structure;

[0033] A movable seat 7 is installed on one side of the spring 6, and a convex column 11 is connected to the top of the movable seat 7 and is slidably connected to the guide hole 10. A positioning column 9 extending to the inner side of the mounting hole 8 is fixedly connected to the surface of the movable seat 7 away from the spring 6, and a guiding inclined surface is arranged at the lower part of the positioning column 9;

[0034] A cutter body 12 is detachably connected to the bottom of the movable seat 7, and a mounting seat 14 plugged into the mounting hole 8 is fixedly connected to the top of the cutter body 12. A positioning hole 13 is provided on the side wall of the mounting seat 14 to match the positioning column 9.

[0035] It should be noted that when the cutting device for producing blister trays that is easy to replace the cutter is in use, the cutter body 12 is manually held so that the mounting seat 14 set at the top corresponds to the mounting hole 8 set at the bottom of the cutter seat 4, and then the mounting seat 14 is connected to the mounting hole 8, and the top edge of the mounting seat 14 is abutted against the guide inclined surface set at the positioning column 9, so that the movable seat 7 is cooperated to compress and deform the spring 6 inside the storage cavity 5. After the mounting seat 14 is completely embedded in the inner side of the mounting hole 8, the positioning hole 13 opened on the side wall of the mounting seat 14 corresponds to the positioning column 9, so that the elastic force of the spring 6 is used to make the positioning column 9 dock with the positioning hole 13, so that the assembly of the cutter body 12 can be quickly completed. When disassembling, it is only necessary to drag the convex column 11 to cooperate with the guide hole 10 to slide, so that the positioning column 9 is separated from the positioning hole 13, which simplifies the replacement steps of the cutter body 12 and makes the replacement easier.
