[0002] The production of packaging bags such as cement bags and chemical bags usually uses paper rolls as the core raw material and is completed through multiple processes such as gluing, cutting, and bag making.

[0003] In the cutting process, the cutter is the core component for cutting materials. Its specifications, shape, and blade condition must match the size and material characteristics of the product to be processed. Due to the diverse application scenarios of packaging bags, different customers have significant differences in their requirements for the size, load-bearing capacity, and opening method of packaging bags. This leads to the need to frequently change the cutter according to different product specifications during the actual production process. Currently, the cutter replacement process usually requires the use of multiple tools for disassembly and installation. The operation steps are numerous and require high skills from the operators, which also consumes a lot of time. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0022] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0023] Reference Figure 1-5 A clamping and releasing mechanism for a cutting blade includes a support plate 1. Several clamps 2 are hinged to both sides of the support plate 1 along its length. Each clamp 2 has a U-shaped structure, and its opening is clamped to the side of the support plate 1. A blade plate 4 for mounting a cutting blade 3 is detachably mounted between the top surface of the support plate 1 and the clamps 2. A slidable connecting rod 5 is mounted on the bottom of the support plate 1. A push block 6 is mounted on the connecting rod 5 corresponding to the opening of the clamp 2. An inclined surface 7 is provided on the clamp 2 corresponding to the push block 6. During installation, the blade plate 4 is inserted between the top surface of the support plate 1 and the clamp 2. Pulling the connecting rod 5 causes the push block 6 to slide along the inclined surface 7, rotating the clamps 2 and pressing the blade plate 4 onto the support plate 1. During disassembly, pushing the connecting rod 5 resets the clamps 2, allowing the blade plate 4 to be easily pulled out without external force applied. The operation is simple and convenient.

[0024] The bottom of the support plate 1 is provided with a sliding groove 8, and the connecting rod 5 is installed in the sliding groove 8. The sliding groove 8 is located at the position of the clamp 2 and has a notch 9 in the direction of the clamp 2. The two sides of the push block 6 extend into the notch 9, and the inclined surface 7 is located at the notch 9. Since the cutter 3 is facing the product, the bottom of the support plate 1 is suitable for installation on the machine. When assembled on the machine, only the bottom of the support plate 1 abuts against the installation position, and the entire push block 6 is hidden inside the support plate 1. The design of all components extending beyond the bottom of the support plate 1 can reduce the structure of the assembly surface and make installation more convenient.

[0025] One end of the connecting rod 5 is equipped with a swing arm 10 that rotates synchronously with the rotating nut 11. A guide wheel 12 is mounted at the end of the swing arm 10. The support plate 1 has an end bearing 13 mounted on the same end as the swing arm 10. The end bearing 13 has an "L"-shaped groove 14, and the guide wheel 12 is movably mounted within the "L"-shaped groove 14. The other end of the support plate 1 is equipped with a spring 17 to reset the connecting rod 5. When a worker rotates the rotating nut 11 using a tool (such as a wrench), the swing arm 10 rotates synchronously, causing the guide wheel 12 to rotate around the rotating nut. When the guide wheel 12 rolls relative to the nut within the "L"-shaped groove 14, the swing arm 10 moves accordingly. (At the same time, the spring 17 will be further compressed. After the movement is completed, the length direction of the swing arm 10 is consistent with the stretching direction of the spring 17.) Move the rotating nut 11 outward to push out the connecting rod 5. At this time, the push block 6 moves towards the clamp 2 and slides along the inclined plane 7 to make the clamp 2 rotate, thereby pressing the blade 4 onto the support plate 1, thus completing the installation of the blade 4. When the worker rotates the rotating nut 11 in the opposite direction, the length direction of the swing arm 10 forms an angle with the stretching direction of the spring 17, and the spring 17 can pull the connecting rod 5 to reset. At this time, the blade 4 can be pulled out.

[0026] The L-shaped groove 14 has a slot 15 on its side wall along the length of the support plate 1. After the blade plate 4 is installed, the guide wheel 12 is engaged in the slot 15 to limit the movement and prevent it from being released automatically.

[0027] The two symmetrical clips 2 are connected at their bottoms by a tension spring 16. When the blade plate 4 is not inserted, the tension spring 16 pulls the clips 2 tight, causing the clips 2 to tend to move away from the top surface of the support plate 1. This keeps the distance between the clips 2 and the top surface of the support plate 1 at its maximum, making it easier to insert the blade plate 4.

[0028] The support plate 1 has several hinge seats 18 arranged along its length on both sides, and the clip 2 is hingedly installed in the hinge seat 18.

[0029] The blade plate 4 is provided with a number of mounting holes 19 for adapting to different cutting blades, which can be compatible with the installation requirements of cutting blades of different specifications and types, expand the applicability of the mechanism, eliminate the need to customize blade plates for different cutting blades, and reduce equipment adaptation costs.
