Multiple sets of cutters 25 are arranged on the outer wall of the rotary cutter disc 24 and are evenly distributed on the outer wall of the rotary cutter disc 24. The cutter changing window 26 is opened on the side wall of the rotary cutter holder 2. The bottom of the rotary cutter holder 2 is provided with an anti-slip component. During operation, a sterile bag is placed on the top of the vehicle body 1, and the rotary cutter disc 24 is placed on top of the sterile bag. On the nozzle of the sterile bag, open the safety assembly and rotate the rotating handle 23. The rotating handle 23 drives the rotating shaft 22 and the rotating cutter disc 24 to rotate. The rotating cutter disc 24 drives the cutter 25 to cut the sterile bag. When the cutter 25 needs to be replaced, it is replaced through the cutter replacement window 26. After the cutting is completed, lift the rotating handle 23, and the safety assembly will automatically reset, so that the cutter 25 is away from the bottom of the rotating cutter holder 2. This step, by rotating the rotating handle 23 to drive the cutter 25 to cut the sterile bag, forms the sterile bag nozzle cutting structure, which realizes the function of cutting the sterile bag nozzle from the middle of the sterile bag. This solves the problem of deviation in size caused by manual cutting, improves the uniformity of the nozzle size, and facilitates the operation of subsequent tear test.

[0027] like Figure 3 and Figure 4As shown, the safety assembly includes a fixed post 3, a push rod 31, a locking block 32, a locking groove 33, a push-pull handle 34, and a spring 35.

During operation, before using the rotary tool holder 2, the push-pull handle 34 is pulled outward, and the push-pull handle 34 drives the locking block 32 away from the rotating shaft 22. When the blade 25 is released from the slot 33, the spring 35 is compressed. Pressing the rotating handle 23 causes the rotating shaft 22 to move the slot 33 away from the locking block 32, releasing the push-pull handle 34. The locking block 32 then contacts the outer wall of the rotating shaft 22. After cutting, pulling the rotating handle 23 moves the blade 25 away from the bottom of the rotating blade holder 2. The rotating handle 23 moves the rotating shaft 22 and the slot 33 closer to the locking block 32. Under the elastic force of the spring 35, the locking block 32 inserts into the slot 33, fixing the rotating shaft 22 to the middle of the cover plate 21. This step, by pulling the push-pull handle 34 to disengage the locking block 32 from the slot 33, forms a locking protection structure for the rotating shaft 22. This achieves the function of retracting the blade 25 into the rotating blade holder 2 when not in operation, reducing the possibility of the blade 25 scratching other items and improving the safety of the device during use.

The clamping plate 41 is connected to the outer wall of the tool holder 4 by fixing bolts. The tool 25 is clamped between the tool holder 4 and the clamping plate 41. During operation, when the tool 25 needs to be replaced, the fixing bolt in the middle of the clamping plate 41 is loosened, the clamping plate 41 moves away from the tool holder 4, the tool 25 is released, a new tool 25 is inserted, and the fixing bolt is tightened. The clamping plate 41 and the tool holder 4 clamp and fix the tool 25 to the outer wall of the rotary cutter disc 24. This step, by clamping and fixing the tool 25 with the tool holder 4 and the clamping plate 41, forms a fixing structure that facilitates the replacement of the tool 25, realizes the function of fixing the tool 25, and improves the convenience of tool 25 replacement.

[0029] like Figure 1As shown, the moving component includes casters 5 and a push handle 51; the casters 5 are fixedly connected to the bottom of the vehicle body 1; multiple sets of casters 5 are provided at the bottom of the vehicle body 1 and are evenly distributed at the four corners of the bottom of the vehicle body 1; the push handle 51 is fixedly connected to the side wall of the vehicle body 1; when the device needs to be moved during operation, the push handle 51 is pushed or pulled, and the vehicle body 1 is moved by the casters 5; this step of moving the vehicle body 1 by the casters 5 constitutes the device moving structure, realizes the function of moving the vehicle body 1, and improves the convenience of moving the device.

[0030] like Figure 3 As shown, the anti-slip component includes anti-slip texture 6; the anti-slip texture 6 is formed at the bottom of the rotary cutter holder 2; during operation, when the rotary cutter holder 2 presses on the sterile bag, the anti-slip texture 6 contacts the sterile bag, increasing the friction between the bottom of the rotary cutter holder 2 and the sterile bag, reducing the deviation of the sterile bag when the cutter 25 cuts the sterile bag, and improving the smoothness of the sterile bag cutting.

[0031] During operation, the sterile bag to be tested is placed on top of the vehicle body 1. The safety component on the cutting assembly is opened, and the nozzle part is cut using the cutting assembly. The nozzle part is then placed on the quick-clamp test assembly for a tear test. The fixing assembly is used to fix the cutting blade on the cutting assembly, and the device is moved by the moving assembly. The cut nozzle part is placed on top of the tension well 13 and the column 17. The quick clamp 15 on the fixing block 14 presses the nozzle part against the top of the column 17. The cylinder 12 is activated, and the cylinder 12 drives the top platform 16 to contact the nozzle part and push it upward. A tear test is conducted in conjunction with the column 17. After the test, the quick clamp 15 is opened, and the nozzle is removed. The sterile bag is placed on top of the vehicle body 1. The rotary cutter disc 24 is placed on the sterile bag nozzle. The safety assembly is opened, and the rotating handle 23 is turned. The rotating handle 23 drives the rotating shaft 22 and the rotary cutter disc 24 to rotate.

Press the rotating handle 23, and the rotating shaft 22 moves the locking slot 33 away from the locking block 32. Release the push-pull handle 34, and the locking block 32 contacts the outer wall of the rotating shaft 22. After cutting is completed, pull the rotating handle 23, and the blade 25 moves away from the bottom of the rotating blade holder 2. The rotating handle 23 moves the rotating shaft 22 and the locking slot 33 closer to the locking block 32. The locking block 32 is inserted into the locking slot 33 under the elastic force of the spring 35, fixing the rotating shaft 22 to the middle of the cover plate 21. Replacement is required. When the cutter 25 is in use, loosen the fixing bolt in the middle of the clamping plate 41, move the clamping plate 41 away from the cutter holder 4, release the cutter 25, replace it with a new cutter 25, tighten the fixing bolt, and the clamping plate 41 and the cutter holder 4 clamp and fix the cutter 25 to the outer wall of the rotary cutter disc 24; when the device needs to be moved, push and pull the push handle 51, and the vehicle body 1 is moved by the universal wheels 5; when the rotary cutter holder 2 is pressed on the sterile bag, the anti-slip texture 6 contacts the sterile bag, increasing the friction between the bottom of the rotary cutter holder 2 and the sterile bag, reducing the deviation of the sterile bag when the cutter 25 cuts the sterile bag, and improving the smoothness of the sterile bag cutting.
