[0002] In the field of membrane material processing, membrane material cutting devices are key equipment specifically designed for cutting membrane materials. Their working principle involves cutting the membrane material by pressing down on the cutting blade. In actual production, due to differences in material, thickness, and hardness among different types of membrane materials, producers often need to change the cutting blade according to the specific characteristics of the membrane material to ensure cutting efficiency and quality. Currently, traditional membrane material cutting devices have certain shortcomings in the way the cutting blade is fixed. Most devices directly use multiple bolts to fix the cutting blade to the base in an inverted manner. When the cutting blade needs to be replaced, the operator has to remove these bolts one by one, and after replacement, reinstall them one by one. This operation method makes the entire replacement process cumbersome, time-consuming, and seriously affects production efficiency. Furthermore, with technological advancements, some improved technical solutions have emerged, such as the membrane material cutting device disclosed in Chinese utility model patent CN218785605 U. This device addresses some of the problems inherent in traditional cutting devices, but it still has shortcomings. The process of changing the cutting blade remains inconvenient and complex, and operators may face certain safety risks during the process, resulting in poor overall safety. Utility Model Content

[0017] like Figure 2 As shown, the specific structure of the quick clamping mechanism 2 includes a sliding hole 21, a double-ended screw 22, a movable block 23, a locking head 24, a pressure block 25, a pressure block cavity 26, a second spring 27, a clamping head 28, a second clamping hole 29, an ejection block 210, and an ejection hole 211. The sliding hole 21 is horizontally arranged inside the upper side of the cutting seat 1. A pressure block cavity 26 is provided on both the left and right lower sides of the sliding hole 21, and a second clamping hole 29 is opened on the lower side of each pressure block cavity 26. The double-ended screw 22 is movably connected inside the sliding hole 21, and a locking head 24 is fixedly connected to both the left and right ends of the double-ended screw 22. There are two movable blocks 23, which are movably connected to the left and right sides of the sliding hole 21 respectively. The threaded hole in the center of each movable block 23 is connected to the external threads on the left and right sides of the double-ended screw 22. Each of the two movable blocks 23 is fixedly connected to a pressure block 25 at its bottom, and the pressure block 25 is movably connected to the corresponding pressure block cavity 26.

[0018] like Figure 3As shown, the locking head 24 has an internal hexagonal hole at the center of its outer side.

[0019] The cutting blade 13 has chamfers on both sides of its upper side; the cutting pressure plate 11 has a protective layer on its bottom surface.

[0020] The usage state of this utility model is as follows: This utility model has a reasonable and simple structure, low production cost, convenient installation, and complete functions. During installation, first carefully inspect the cutting seat 1. The cutting seat 1 is equipped with a quick clamping mechanism 2, and its bottom surface has a central mounting groove 3. Several guide holes 5 are distributed on the left and right sides of the cutting seat 1. The movable rod 7 is in the initial position under the action of spring 6. The slot 10 on the lower side of the movable rod 7 is empty at this time, waiting for subsequent connection. Next, the upper side of the cutting blade 13 is placed into the mounting groove 3. The slots 4 on its left and right sides correspond to the lower side of the quick clamping mechanism 2, which facilitates the connection. It is worth mentioning that the cutting... The chamfered design on both sides of the upper side of the blade 13 makes the insertion process smoother. After the cutting blade 13 is inserted into the opening of the mounting slot 3 above the cutting seat 1, the locking head 28 will quickly lock into the slot 4 under the action of the spring 27, ensuring that the cutting blade 13 will not fall out, providing convenience for subsequent fixing operations. When using the quick clamping mechanism 2 for fixing, an Allen wrench can be used to rotate the double-ended screw 22 through the Allen hole in the center of the outer side of the locking head 24 at both ends of the double-ended screw 22. As the double-ended screw 22 rotates, the two movable blocks 23 connected to it by threads move towards each other in the sliding hole 21, and the pressure block 25 at the bottom of the movable block 23 moves accordingly. The pressure block cavity 26 moves and presses against the clamping head 28, causing the clamping head 28 to move further into the slot 4 and clamp, thereby firmly fixing the cutting blade 13 onto the cutting seat 1, ensuring that the cutting blade 13 will not shake during the cutting process. When installing the cutting pressure plate 11, first place it in a suitable position so that the blade groove 12 in the center of the cutting pressure plate 11 is accurately fitted onto the lower outer side of the cutting blade 13. At this time, the movable rod 7 located in the guide holes 5 on the left and right sides of the cutting seat 1, under the elastic force of the spring 6, has its lower outer slot 10 exactly aligned with the threaded hole position on the side of the left and right side slot holes 8 on the cutting pressure plate 11. Then, tighten the locking screw 9. Screw it into the threaded hole on the side of the card hole 8 so that its inner side connects with the corresponding card slot 10, further fixing the cutting pressure plate 11. In addition, the protective layer on the bottom surface of the cutting pressure plate 11 can effectively prevent damage to the film during the cutting process. When the film is being cut, the cutting seat 1 moves downward, the cutting pressure plate 11 contacts the film first, and then the cutting blade 13 cuts the film. If the cutting blade 13 needs to be replaced, simply reverse the above installation steps and push the push-out block 210 to make the cutting blade 13 quickly disengage from the mounting slot 3, making it easy to replace the new cutting blade. After the replacement is completed, reinstall the cutting blade according to the above installation steps, and the cutting work can continue.
