[0011] 1. The packaging film hot cutting knife group is provided with a clamping column, a spring 1, a pull rod, a clamping block, a clamping hook, a pressure rod and a limit rod. When the pull rod is pulled, the pull rod clamping block moves backward, and the clamping block squeezes the spring to drive the clamping column to move backward, so that the clamping hook and the clamping block are disengaged. Then, by pressing the limit rod, the limit rod moves and squeezes the spring 2, so that one end of the rotating rod is disengaged from the clamping connection of the drive shaft. The rotating rod and the upper cutting knife group can be removed as a whole for cleaning and maintenance, which abandons the traditional packaging film cutting knife group which is mostly fixed by bolts. After long-term use, the scraps of the packaging film are easy to remain in the knife group. When cleaning, there is no need to unscrew multiple bolts to remove the knife group for cleaning, which is easy to operate and improves work efficiency.

[0012] 2. The packaging film hot-cutting knife group is provided with a motor, a driving shaft, a pressure plate, two springs and a limit rod. When in use, the rotating rod is sleeved on the driving shaft. The limit rod is pressed during installation, and the limit rod squeezes the spring to move the limit rod backward. When the limit rod corresponds to the hole on the rotating shaft, the spring rebounds and automatically engages with the rotating rod. The installation is convenient. Start the motor, the motor drives the driving shaft to rotate, and the driving shaft drives the upper cutting knife group to rotate, and the packaging film is automatically cut without excessive manual operation, which brings convenience to the packaging film cutting.

A support plate 2 is fixedly installed on the top of one side of the base 1, and a lower pressing shaft 23 is rotatably connected to the inner wall of the support plate 2, and a lower pressing wheel 24 is provided on the outer wall of the lower pressing shaft 23, and the end of the lower pressing shaft 23 away from the support plate 2 is connected to the support plate 2 10. Because the lower pressing wheel 24 is provided, after the packaging film is cut, the cutting mouth is smoother after being pressed by the lower pressing wheel 24, and the cutting effect is better.

[0020] A hook 25 is fixedly installed on one side of the support plate 1 2 and the support plate 2 10, respectively. One end of the hook 25 is rotatably connected to a film placing rack 26. By setting the hook 25 and the film placing rack 26, the packaging film to be cut can be placed on the film placing rack 26, and there is no need to manually hold the packaging film for a long time, thereby reducing the workload. A limit plate 3 is fixedly installed on the inner wall of the support plate 1 2, and a clamping column 4 is provided on the inner wall of the limit plate 3. A spring 1 5 is connected to the outer sleeve of the clamping column 4. A clamping block 6 is fixedly installed on one end of the clamping column 4. A pull rod 7 is connected to the upper side of the clamping block 6. A clamping hook 8 is clamped on one end of the clamping block 6, and a fixing plate 9 is fixedly connected to the lower side of the clamping hook 8.

[0021] A rotating shaft 18 is provided on one side of the fixed plate 9, and a rotating rod 19 is rotatably connected to the end of the rotating shaft 18.
