DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] The utility model provides a technical solution: Figure 1-Figure 5 As shown, in this embodiment, a hot-cutting bag-making machine for packaging bags comprises a conveying device 1, a mounting plate 2 is arranged above the conveying device 1, support plates 3 are fixedly mounted on both ends of the mounting plate 2, a cutter 4 is installed at the bottom end of the mounting plate 2, and a scraping component is arranged on one side of the cutter 4;

[0026] Among them, the scraping assembly includes a scraper 5 arranged on one side of the cutter 4, and the bottom end of the scraper 5 is provided with a mounting seat 6 through the mounting assembly. A movable plate 7 is fixedly connected to one side of the mounting seat 6. A threaded rod 20 is embedded in the inner wall of the top of the movable plate 7. The threaded rod 20 is rotatably installed inside the mounting plate 2, and one end of the threaded rod 20 is connected to a motor 21.

[0027] By setting the scraping component, when the cutter 4 needs to be cleaned, the motor 21 can be started by PLC control, the start of the motor 21 drives the rotation of the threaded rod 20, the rotation of the threaded rod 20 drives the movement of the movable plate 7, the movement of the movable plate 7 drives the movement of the mounting seat 6, the movement of the mounting seat 6 drives the movement of the scraper 5, so that the scraper 5 moves to scrape off the residues adhered to the outer wall of the bottom end of the cutter 4, and the scraped residues fall into the collection box 16 for collection, thereby avoiding the problem of sticking to the knife in the current hot-cut bag making machine when manufacturing packaging bags, because the cutter 4 works at high speed and high temperature, which will soften or melt some packaging bag materials, and the adhered residues may make the sealing of the subsequent packaging bags imperfect and produce defects, which ultimately affect the quality of the finished product, thereby ensuring the quality of the finished product of the packaging bag.

[0028] like Figure 1-Figure 5 As shown, a baffle 12 is provided at the bottom end of the mounting seat 6 , and the baffle 12 is rotatably connected to the mounting seat 6 via a rotating shaft 13 .

[0029] A collecting box 16 is formed between the mounting seat 6 and the baffle 12 to collect the residues scraped by the scraper 5 .

[0030] like Figure 1-Figure 5 As shown, the mounting assembly includes a connecting plate 9 arranged inside the scraper 5, a spring 11 is arranged on one side of the connecting plate 9, a fixing block 8 is fixedly connected to the bottom end of the connecting plate 9, the fixing block 8 is embedded in the fixing groove 19, and the fixing groove 19 is opened inside the mounting seat 6.

[0031] Through the setting of the installation component, when the scraper 5 needs to be installed, the scraper 5 is embedded in the inner wall of the mounting seat 6 and slides downward. The movement of the scraper 5 drives the movement of the fixing block 8. When the fixing block 8 slides to one side of the fixing groove 19, the elastic potential energy released by the spring 11 pushes the fixing block 8 to be embedded in the interior of the fixing groove 19 for fixation.

[0032] like Figure 1-Figure 5 As shown, the bottom end of the fixing block 8 is arranged at an incline.

[0033] When installing the scraper 5, the scraper 5 is embedded in the inner wall of the mounting seat 6 and slides downward, and the inclined surface of the fixing block 8 contacts the inner wall of the mounting seat 6 and moves inward, and the installation method is simple.

[0034] like Figure 1-Figure 5 As shown, a fixing plate 10 is fixedly mounted on the top end of the connecting plate 9 .

[0035] When the scraper 5 needs to be removed, first move the fixing plate 10 to the side away from the mounting seat 6. The movement of the fixing plate 10 drives the movement of the connecting plate 9. The movement of the connecting plate 9 drives the fixing block 8 to slide out from the inside of the fixing groove 19 and then pull the scraper 5 upward for replacement.

[0036] like Figure 1-Figure 5 As shown, one end of the rotating shaft 13 is fixedly connected to a gear 14 , the bottom end of the gear 14 is meshed with a rack plate 15 , the rack plate 15 is fixedly mounted on the top of a collecting box 16 , and the collecting box 16 is fixedly mounted on one side of the supporting plate 3 .

[0037] The movement of the mounting seat 6 drives the movement of the baffle 12 and the rotating shaft 13 , and the movement of the rotating shaft 13 drives the movement of the gear 14 . When the gear 14 engages with the rack plate 15 , it rotates, thereby rotating the baffle 12 , and the residue inside the mounting seat 6 falls into the inside of the drawer 17 .

[0038] like Figure 1-Figure 5 As shown, the interior of the collecting box 16 is slidably connected with a drawer box 17 .

[0039] It is convenient to clean up the collected residues.

[0040] The utility model provides a hot-cutting bag making machine for packaging bags, and the specific working principle is as follows:

[0041] When the cutter 4 needs to be cleaned, the motor 21 can be started by controlling the PLC, the start of the motor 21 drives the rotation of the threaded rod 20, the rotation of the threaded rod 20 drives the movement of the movable plate 7, the movement of the movable plate 7 drives the movement of the mounting seat 6, the movement of the mounting seat 6 drives the movement of the scraper 5, so that the scraper 5 moves to scrape off the residues adhering to the outer wall of the bottom end of the cutter 4, and the scraped residues fall into the inside of the mounting seat 6;

[0042] The movement of the mounting seat 6 drives the movement of the baffle 12 and the rotating shaft 13 , and the movement of the rotating shaft 13 drives the movement of the gear 14 . When the gear 14 engages with the rack plate 15 , it rotates, thereby rotating the baffle 12 , and the residue inside the mounting seat 6 falls into the inside of the drawer 17 .

[0043] When the scraper 5 needs to be replaced, first move the fixing plate 10 to the side away from the mounting seat 6. The movement of the fixing plate 10 drives the movement of the connecting plate 9. The movement of the connecting plate 9 drives the fixing block 8 to slide out from the inside of the fixing groove 19 and then pull the scraper 5 upward for replacement.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
