Through the cooperation of the conveying box 1 and the processing component 200, the cutter head of the cutting device is set to a circular shape, and a cut is made in the middle position of two medical bags. When the two medical bags are opened separately, a notch is left on each medical bag, thereby improving the cutting efficiency of the medical bag incision.

[0029] In this embodiment, the processing assembly 200 is a structure used for production processing and opening.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the processing assembly 200 includes a cutting mechanism installed on the top of the conveying box 1 for opening, and a functional mechanism installed on the top of the conveying box 1 for conveying processing;

[0032] The functional mechanism includes a loading mechanism 216 fixed on the right side of the conveying box 1, a first heat sealing device 210 fixed on the top of the conveying box 1 for plastic sealing, a first transmission device 211 fixed on the top of the conveying box 1 for stable transportation, an adjustment device 212 fixed on the top of the conveying box 1 for adjustment, a second heat sealing device 213 fixed on the top of the conveying box 1 for plastic sealing, a second transmission device 214 fixed on the top of the conveying box 1 for transportation, and a cutting device 215 fixed on the top of the conveying box 1 for cutting.

[0033] It should be noted that a through hole is provided at the top of the L-shaped connecting plate 201 for the output end of the air cylinder 202 to pass through, so that the air cylinder 202 can pass through the L-shaped connecting plate 201, so that the output end of the air cylinder 202 can drive the movable plate 204 and the circular cutting head 206 at the bottom to move downward, and a thread groove is provided at the bottom of the movable plate 204 for the threaded connection of the thread block 205, so that the circular cutting head 206 can be disassembled for operations such as grinding or replacement.

[0034] In addition, a circular hole is provided on the top of the bottom plate 207 for the circular cutting head 206 to pass through. The diameter of the circular hole is equal to the diameter of the circular cutting head 206, so that the circular cutting head 206 can pass through the inside of the circular hole, thereby cutting an opening.

[0035] At the same time, the inner front side wall of the conveying box body 1 is provided with a slot for the bottom plate 207 to be plugged in, and the top of the bottom plate 207 is provided with a threaded groove. The fixing bolt 209 is threadedly connected in the threaded groove on the top of the bottom plate 207, so that the bottom plate 207 can be disassembled. When it is necessary to replace the circular cutting head 206 of different sizes, it is necessary to replace different bottom plates 207 for mutual use. At the same time, the size of the circular cutting head 206 is equal to the diameter of the circular hole on the bottom plate 207.

[0036] Secondly, the collection box 208 is located directly below the circular hole, and a threaded hole for threaded connection of the fixing bolt 209 is provided on the top of the conveying box body 1, so that the cut plastic discs can be directly dropped into the collection box 208 for collection, so that the plastic discs will not fly around, and it is also convenient to clean the plastic discs.

When the part is in the middle, the cylinder 202 is started, and the cylinder 202 drives the movable plate 204 to move, thereby driving the circular cutting head 206 at the bottom to move downward and penetrate the bottom plate 207, so as to cut a circular cutting opening, and the cut excess circular plastic pieces fall into the collection box 208 for collection, so as to complete the cutting of the opening, and then the second transmission device 214 is used to transport them, and the cutting device 215 is used to separate them one by one. At the same time, the segmentation position is located on the center line of the position where the circular hole is cut, so that the medical packaging bag can be produced, and each packaging bag can have a semicircular opening on the front and back, which is convenient for tearing the packaging bag.

[0039] Compared with the prior art, the cutter head of the cutting device is set to a circular shape through the mutual cooperation of the conveying box 1 and the processing component 200, and the cut is made in the middle position of the two medical bags. When the two medical bags are opened separately, a notch is left on each medical bag, thereby improving the cutting efficiency of the medical bag cutting. At the same time, the cutter head and the base plate 207 can be disassembled and installed according to actual use requirements, and the cutter heads of different sizes can be replaced or polished, etc., thereby improving the practicality of the cutting and tearing device of the medical bag making machine, and solving the problem that the existing bag making machine needs to make an opening on each packaging bag during use, and cannot make holes on two packaging bags at the same time, resulting in low cutting efficiency and a large number of processing times.
