Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0025] In one embodiment of this utility model, such as Figure 1-3As shown, a filter bag edge-folding metal strip cutting device includes an unwinding device 1, a buffer device 2, and a cutting device 3. The unwinding device 1 is used to unwind the filter bag edge-folding metal strip, and the cutting device 3 is used to cut and form the filter bag edge-folding metal strip. The buffer device 2 is located between the unwinding device 1 and the cutting device 3, and is used to buffer and slow down the conveying speed of the filter bag edge-folding metal strip. The buffer device 2 includes a hanging block 21, a hanging rope 22, a counterweight 23, and a connecting assembly 24. The left and right ends of the connecting assembly 24 are respectively connected to the two hanging blocks 21, one end of the two hanging ropes 22 is respectively connected to the two hanging blocks 21, and the other end of the two hanging ropes 22 is respectively connected to the left and right ends of the counterweight 23. The two hanging blocks 21 are used to hang on the left and right sides of the filter bag edge-folding metal strip. In this embodiment, both the unwinding device 1 and the cutting device 3 are existing technologies. During installation, the filter bag edge metal roll of the unwinding device 1 is pulled out to form a long strip of filter bag edge metal material, which is then placed at the cutting point of the cutting device 3. The buffer device 2 is then hung between the cutting device 3 and the unwinding device 1. Specifically, the inner sides of the two hanging blocks 21 are respectively hung on the left and right sides of the filter bag edge metal material, and the tops of the two hanging blocks 21 are connected by the connecting assembly 24. Then, one end of each of the two hanging ropes 22 is connected to the bottom of each of the two modified blocks 21, and the other end of each hanging rope 22 is connected to the counterweight. The top of the left and right ends of block 23 applies gravity to the filter bag edge metal strip material during the conveying process, reducing its conveying speed and preventing the unwinding speed of the unwinding device 1 from exceeding the cutting speed of the cutting device 3, which would cause the strip material to become blocked, bent, or folded and damaged. This application uses the unwinding device 1, buffer device 2, hanging block 21, hanging rope 22, counterweight block 23, connecting assembly 24, and cutting device 3 to reduce the conveying speed of the filter bag edge metal strip material by applying gravity, preventing the unwinding speed of the unwinding device 1 from exceeding the cutting speed of the cutting device 3, which would cause the strip material to become blocked, bent, or folded and damaged, thereby improving the production quality of the filter bag edge metal strip cutting device.

[0026] like Figure 2-3 As shown, the buffer device 2 further includes a rotating wheel 25. The front and rear ends of the mounting block 21 are provided with mounting portions 211, and the rotating wheel 25 is rotatably mounted on the mounting portions 211. In this embodiment, the rotating wheel 25 is installed on the two mounting portions 211 at the front and rear ends of the inner top surface of the mounting block 21. When the mounting block 21 is hung on the left and right sides of the filter bag folding metal strip, the rotating wheel 25 abuts against the surface of the filter bag folding metal strip, and the rotating wheel 25 will not scratch the moving strip, thereby improving the production quality of the filter bag folding metal strip cutting device.

[0027] like Figure 2-3As shown, the connecting assembly 24 includes an adjusting screw 241 and an adjusting block 242. The adjusting block 242 is mounted on the top surface of the mounting block 21, and the left and right ends of the adjusting screw 241 are respectively mounted on the two adjusting blocks 242. The adjusting block 242 can move left and right along the length direction of the adjusting screw 241. In this embodiment, two adjusting blocks 242 are respectively mounted on the top surface of each mounting block 21. The two mounting blocks 21 are connected to each other by two adjusting screws 241, and the adjusting screws 241 and the adjusting blocks 242 have a threaded installation structure, so that the mounting block 21 can move left and right along the length direction of the adjusting screw 241. During adjustment, only the adjusting screw 241 needs to be rotated to adjust the distance between the two mounting blocks 21, so as to achieve the purpose of conveying metal strips for folding filter bags of different widths, which is beneficial to improving the versatility of the filter bag folding metal strip cutting device.

[0028] like Figure 2-3 As shown, the connecting assembly 24 further includes a first limiting nut 243, which is installed on the adjusting screw 241 and can abut against the outer side of the adjusting block 242. In this embodiment, the first limiting nut 243 is installed at both ends of the adjusting screw 241, and the first limiting nut 243 is fitted against the outer side of the adjusting block 242. The first limiting nut 243 can play a limiting role, so even if the adjusting screw 241 is rotated, the two mounting blocks 21 cannot be moved away from each other, thus preventing the two mounting blocks 21 from being misadjusted.

[0029] like Figure 2-3 As shown, the connecting assembly 24 further includes a second limiting nut 244, which is installed on the adjusting screw 241 and can abut against the inner side of the adjusting block 242. In this embodiment, the second limiting nuts 244 are respectively installed at the left and right ends of the adjusting screw 241, and the second limiting nuts 244 are fitted against the inner side of the adjusting block 242. The second limiting nuts 244 can play a limiting role, so even if the adjusting screw 241 is rotated, the two mounting blocks 21 cannot be brought closer to each other, thus preventing the two mounting blocks 21 from being misadjusted.

[0030] like Figure 2-3As shown, the mounting block 21 has a first mounting hole 212, the top of the counterweight block 23 has a connecting block 231, the connecting block 231 has a second mounting hole 2311, one end of the suspension rope 22 is installed in the first mounting hole 212, and the other end of the suspension rope 22 is installed in the second mounting hole 2311. In this embodiment, each mounting block 21 has two first mounting holes 212, and the top of the counterweight block 23 has four connecting blocks 231, which are located at the four corners of the top of the counterweight block 23. Each mounting block 21 is connected to the end of the counterweight block 23 by two suspension ropes 22, that is, the counterweight block 23 is connected to two mounting blocks 21 by four suspension ropes 22. Specifically, one end of the suspension rope 22 is installed in the first mounting hole 212, and the other end of the suspension rope 22 is installed in the second mounting hole 2311, which is convenient and quick.

[0031] like Figure 2-3 As shown, the mounting block 21 is provided with a plurality of hook holes 213, which are evenly spaced along the length of the mounting block 21 and are located outside the first mounting hole 212. In this embodiment, each mounting block 21 is provided with six hook holes 213 along its front-back direction. In use, the end of the suspension rope 22 is pulled upward through the first mounting hole 212, and the end of the suspension rope 22 is hooked onto the hook hole 213, thereby adjusting the distance between the mounting block 21 and the counterweight block 23.
