[0036] The following refers to Figures 1-3 The cutting mechanism for cutting the packaging bag according to the embodiment of the utility model is described.
[0037] Embodiment one
[0038] As Figures 1-3 The cutting mechanism includes a cutter seat 100, the top of the cutter seat 100 forms a flat end face, and guide columns 110 are arranged on both sides of the cutter seat 100, and the bottom of the guide column 110 is fixedly connected with the cutter seat 100. The distance between the two guide columns 110 is the cutting area.
[0039] The two ends of the cutter assembly 200 are sleeved with the guide columns 110 and slide along the extension direction of the guide columns 110. That is, the cutter assembly 200 can be pressed to the surface of the cutter seat 100, so as to cut the packaging bag on the surface of the cutter seat 100. The reset spring 210 is arranged between the cutter assembly 200 and the guide column 110, one end of the reset spring 210 abuts against the top limiting block 111 of the guide column 110, and the other end abuts against the top end face of the cutter assembly 200. During the process of cutting the packaging bag by pressing the cutter assembly 200, the reset spring 210 is in a stretched state, and the elastic potential energy increases. When the external force of the cutter assembly 200 is removed, the elastic potential energy of the reset spring 210 is released, pulling the cutter assembly 200 to rise and reset.
[0040] A copper strip 120 is arranged on the surface of the cutter base 100, and the copper strip 120 is located directly below the cutter assembly 200. The cutting line of the packaging bag is located on the surface of the copper strip 120. The cutter assembly 200 is pressed onto the copper strip 120 to cut the packaging bag, thereby completing a cutting process. During each cutting process, part of the debris generated by the heated cutting at the cutting line of the packaging bag is adhered to the copper strip 120. Long-term use requires that the staff clean the surface debris and maintain the equipment during shutdown, but the shutdown maintenance directly affects the production efficiency.
[0041] In this embodiment, a debris scraping groove seat 300 is arranged at one end of the copper strip 120. The scraper part 310 of the debris scraping groove seat 300 is attached to the surface of the copper strip 120. After each cutting, the debris scraping groove seat 300 is scraped once along the extension direction of the copper strip 120 by the scraper part 310, so that the surface residual debris can be removed, and the long-term stable operation of the equipment is ensured.
[0042] The groove seat driving assembly is arranged on one side of the cutter base 100. The output end of the groove seat driving assembly is connected with the debris scraping groove seat 300 for pushing the debris scraping groove seat 300 to scrape along the extension direction of the copper strip 120. The output force of the groove seat driving assembly makes the debris scraping groove seat 300 slide and scrape.
[0043] The working principle of the cutting mechanism for cutting the packaging bag in this embodiment is as follows. The packaging bag is conveyed to the cutter base 100 under the action of the conveying belt. The cutting line of the packaging bag is located on the copper strip 120. The cutter assembly 200 above is pressed to cut the packaging bag. The cut packaging bag is discharged from the cutting area. The groove seat driving mechanism drives the debris scraping groove seat 300 to move from one end of the copper strip 120 to the other end. The debris scraping groove seat 300 scrapes the debris on the copper strip 120 by the scraper part 310 and collects the debris, so as to keep the surface of the copper strip 120 clean.
[0044] Embodiment two
[0045] As shown in Figure 3 The debris scraping groove seat 300 includes a middle rib plate 301 and a baffle 302 connected on both sides of the rib plate 301. The rib plate 301 and the baffle 302 are integrally formed to form a tapered structure platform. The baffle 302 and the rib plate 301 surround the symmetrical scraping groove area 303. The bottom of the scraping groove area 303 is inclined downward away from the rib plate 301 side.
[0046] Specifically, the scraping groove area 303 is distributed on both sides of the rib plate 301 as the center of symmetry, and the debris scraping groove seat 300 can scrape the pad copper strip 120 through the scraper part 310 each time it slides. When the debris scraping groove seat 300 slides forward, the scraper part 310 of the scraping groove area 303 moving in the same direction scrapes the surface of the pad copper strip 120, and the scraping groove area 303 moving in the opposite direction is in standby state. When the debris scraping groove seat 300 slides reversely, the scraping groove area 303 moving in the opposite direction is in the same direction moving state and scrapes the pad copper strip 120.
[0047] Embodiment three
[0048] As shown in Figure 3 , the scraper part 310 is detachably mounted on the bottom inclined surface of the scraping groove area 303. The scraper part 310 adopts a detachable structure, which facilitates replacement of the scraper part 310 and facilitates equipment operation and maintenance.
[0049] Embodiment four

The slide rail part 412 is provided with a sliding block seat 413 that cooperates with each other, the sliding block seat 413 is connected with the debris scraping groove seat 300, and the sliding block seat 413 slides along the slide rail part 412 to drive the debris scraping groove seat 300 to scrape the surface of the pad copper strip 120. Specifically, the length of the fixed seat 411 is not less than the length of the pad copper strip 120, and the length of the slide rail part 412 is not less than the length of the pad copper strip 120 and is embedded in the fixed seat 411. The sliding block seat 413 slides on the surface of the slide rail part 412, and the sliding seat slides synchronously with the debris scraping groove seat 300 to scrape the surface debris of the pad copper strip 120.
[0051] Embodiment five
[0052] As shown in Figure 2 , the sliding block seat 413 and the debris scraping groove seat 300 are connected through a U-shaped support frame 414, one end of the U-shaped support frame 414 is connected with the surface of the sliding block seat 413, and the other end is connected with the side wall of the debris scraping groove seat 300. The two ends of the U-shaped support frame 414 are connected with the debris scraping groove seat 300 and the sliding block seat 413 respectively, and the U-shaped support frame 414 is used as a fixing piece. The end surface of the U-shaped support frame 414 and the debris scraping groove seat 300 are detachably connected by screws, which facilitates disassembly of the U-shaped support frame 414 for maintenance of the electromagnetic slide rail and the debris scraping groove seat 300.
