[0015] Specific Embodiment 1: Please refer to Figure 1-2A plastic bag processing hot cutting device comprises an operating table 10; a bracket 12 is fixedly arranged on the upper end of the operating table 10; a pair of electric cylinders 13 are arranged on the bracket 12; the output ends of the pair of electric cylinders 13 are fixedly connected to a cutter 14; it also comprises a pair of fixed blocks 17 fixedly connected to the upper end surface of the operating table 10; a pair of sliding blocks 19 are respectively arranged on the front sides of the fixed blocks 17; two springs 18 are arranged between the fixed blocks 17 and the sliding blocks 19 on each side; the fixed blocks 17 and the sliding blocks 19 on the same side are elastically connected by two springs 18; a rotating roller 22 is rotatably connected between the two fixed blocks 17; a rotating roller 22 is rotatably connected between the two sliding blocks 19 Connecting roller one 16; scrapers 20 are respectively arranged on the outer sides of roller two 22 and roller one 16; the two scrapers 20 respectively abut against the roller surfaces of roller two 22 and roller one 16; a heater 11 is fixedly arranged on the upper end of the operating table 10; the output ends of the two heaters 11 are fixedly connected to the scraper 20 on the side where roller two 22 is located; by arranging a fixed block 17, a sliding block 19, roller one 16, and roller two 22, the surface of the cutter 14 is cleaned by the rollers of roller one 16 and roller two 22 during the descending process, and then the scraper 20 is used to scrape off the waste residue on the surface of roller one 16 and roller two 22, thereby improving the hot cutting efficiency and hot cutting effect.

[0016] See also Figure 2 The fixed block 17 and the sliding block 19 are rotatably connected to the caressing plate 21 respectively; by setting the caressing plate 21, the caressing plate 21 can discharge the waste scraped by the scraper 20 to the surface of the uncut plastic bag, thereby improving the hot cutting efficiency and preventing the hot cutting from being affected.

[0017] See also Figure 2 A slideway 15 is arranged on the outer side of a pair of sliding blocks 19 ; the sliding blocks 19 on the same side are slidably connected to the slideway 15 .

[0018] During operation, the plastic bag is fed under the cutting knife 14. The plastic bag is flattened by the flattening plate 21. After reaching the cutting position, the electric cylinder 13 is activated. The output end of the electric cylinder 13 drives the cutting knife 14 to press down. The heater 11 is activated. The output end of the heater 11 generates heat, heating the scraper 20 on one side of the second roller 22. Subsequently, the heat is transferred from the scraper 20 to the second roller 22, indirectly heating the cutting knife 14. When the cutting knife 14 passes between the first roller 16 and the second roller 22, the first roller 16 is pushed to the front side. The second roller 22 and the first roller 16 clean the surface of the cutting knife 14. Subsequently, the cutting knife 14 is heated and cuts the plastic tape. After cutting is completed, the electric cylinder 13 lifts, driving the cutting knife 14 to rise. Subsequently, the second roller 22 and the first roller 16 roll and press against the surface of the cutting knife 14, cleaning the surface of the cutting knife 14 again. As the second roller 22 and the first roller 16 rotate, the waste residue on the surfaces of the second roller 22 and the first roller 16 is scraped off by the scraper 20. When the waste residue accumulates to a certain amount, it falls onto the upper surface of the flattening plate 21 and then slides onto the surface of the plastic bag, facilitating cleaning.
