[0003] In the prior art, the cutting machines on the market usually do not have a good protective device, which causes the cutting blade to be directly exposed to the external environment. After the cutting machine completes the cutting work of the plastic bag, in order to ensure that the cutting machine can perform the cutting work normally, the cutting machine is usually cleaned and maintained regularly. When the maintenance personnel clean and maintain the cutting machine, since the cutting blade is directly exposed to the outside world, it is easy for the maintenance personnel to accidentally touch the blade, and the blade surface is relatively sharp, which can easily scratch the maintenance personnel, thereby causing unnecessary harm to the maintenance personnel. After searching, it was found that the technical solution provided by the utility model with application number 202021240317.X also has the above-mentioned problems. Therefore, a cutting device for preparing degradable plastic bags is needed. Utility Model Content

[0009] According to the cutting device for preparing degradable plastic bags, a fixing groove is provided on the connecting plate, and the outer surface of the fixing block is movably connected to the fixing groove, which facilitates the connection and fixation between the first protective shell and the second protective shell.

[0010] According to the cutting device for preparing degradable plastic bags, a slide groove is provided on the connecting plate, and the outer surface of the slider is slidably connected to the slide groove, so that the slider can only move in the horizontal direction.

[0011] According to the cutting device for preparing degradable plastic bags, the left surface of the first magnet is magnetically connected to the second magnet, and the side surface of the first protective shell is in contact with the second protective shell.

[0028] Working principle: Under the action of the first protective shell 5 and the second protective shell 6, the blade 2 can be protected so that the blade 2 will not be exposed to the outside world. When the cutting machine 1 needs to be used to cut plastic bags, the concave block 17 is pushed so that the moving concave block 17 can drive the slider 16 to move horizontally on the limit rod 15. At the same time, the moving slider 16 will squeeze the spring 18 on the inner wall of the connecting plate 14, so that the spring 18 is in a taut state. When the moving concave block 17 no longer contacts the movable block 12, the restriction on the movable block 12 is released, and then the movable block 12 is flipped over so that the movable block 12 and the fixed block 13 can flip over with the connecting shaft 11 on the connecting block 10 as the center axis. When the flipped fixing block 13 is disengaged from the fixing groove 19, the fixation between the first protective shell 5 and the second protective shell 6 is released, and then the first protective shell 5 and the second protective shell 6 are pulled to separate the first protective shell 5 and the second protective shell 6. When the first protective shell 5 and the second protective shell 6 are separated and removed from the cutting machine 1 and the positioning block 3, the blade 2 can be exposed to perform normal cutting work, and then the concave block 17 is released, so that the spring 18 is no longer restricted and rebounds, and the rebound spring 18 can drive the slider 16 to reset in the slide groove 20, so that the moving slider 16 can drive the concave block 17 to move. When the cutting is completed, the first protective shell 5 and the second protective shell 6 are respectively The docking block 4 on the second protective shell 6 is inserted into the positioning groove 9 on the positioning block 3, which can realize the preliminary connection between the cutting machine 1 and the first protective shell 5 and the second protective shell 6, and at the same time complete the protection of the blade 2. When the docking block 4 is inserted into the positioning groove 9, the first magnet 7 and the second magnet 8 can be brought into contact, so that under the magnetic attraction between the first magnet 7 and the second magnet 8, the connection between the first protective shell 5 and the second protective shell 6 can be completed. Then, the first protective shell 5 is pressed and the concave block 17 is pushed, so that the moving concave block 17 can drive the slider 16 to move while keeping the spring 18 in a taut state. When the moving concave block 17 does not affect the flipping of the movable block 12, the movable block 12 is flipped back to make The flipped movable block 12 can drive the fixed block 13 to flip. When the flipped fixed block 13 is inserted into the fixing groove 19, the concave block 17 is released, so that the spring 18 is no longer restricted and rebounds, and then the rebound spring 18 drives the slider 16 and the concave block 17 to move to reset.
