Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0032] Example: See Figure 1-7 A plastic bag hot cutting machine that is easy to clean is shown, comprising an outer support frame 1, a working platform 2, a hot cutting component 3 and a cleaning mechanism. The working platform 2 is installed in the middle of the bottom surface of the inner cavity of the outer support frame 1, and the hot cutting component 3 for cutting paper bags is arranged between the two sides of the top of the outer support frame 1. A cleaning mechanism is installed between the hot cutting component 3 and the working platform 2. A moving component 7 is symmetrically arranged on the top of the working platform 2. A storage component 4 is arranged on one side of the bottom of the inner cavity of the outer support frame 1. A positioning rod 9 is rotatably installed on the side of the inner cavity side wall of the outer support frame 1 away from the storage component 4. A control panel 5 is installed on one side of the outer wall of the outer support frame 1.

[0033] Among them, the control panel 5 is electrically connected to start and shut down all the electrical equipment in the control device;

[0034] The hot cutting assembly 3 includes a connecting frame 301 and a moving platform 304, and the cleaning mechanism includes a rack 1101 and a gear 1102;

[0035] The bottom of the mobile platform 304 is symmetrically provided with mounting blocks 307, and connecting shafts 1103 are rotatably provided in the two mounting blocks 307, and a threaded rod 1104 is installed on the side where the two connecting shafts 1103 are close to each other, and a gear 1102 is installed on the outer wall of the side where the two connecting shafts 1103 are away from each other;

[0036] Racks 1101 are installed on the left and right sides of the top of the working platform 2, and the racks 1101 and the gears 1102 are meshed with each other;

[0037] The threaded rod 1104 is threadedly connected with a moving block 1105, a scraping ring 1108 is installed at the bottom of the moving block 1105, and a through groove 1107 is opened in the middle of the moving block 1105;

[0038] A positioning block 1106 is connected between the two mounting blocks 307, and the positioning block 1106 is slidably arranged in the inner cavity of the through slot 1107;

[0039] The positioning block 1106 is rectangular, and when the moving block 1105 moves, the positioning block 1106 plays a limiting role to prevent the threaded rod 1104 from driving the moving block 1105 to rotate when the threaded rod 1104 rotates.

[0040] In this embodiment, specific reference Figure 1 and Figure 5 A movable groove 6 is provided on one side of the bottom of the inner cavity of the outer support frame 1, and the storage assembly 4 includes a storage box 401, and a sliding block 402 is provided at the bottom of the storage box 401, and a sliding block 402 is slidably installed in the sliding block 402;

[0041] The outer wall of the outer support frame 1 is rotatably mounted with a rotating disk 12 near the moving groove 6. A limit block 13 is arranged on the side wall of the rotating disk 12. The limit block 13 is in an "L" shape. A plurality of convex points 14 are evenly arranged on the side wall of the sliding block 402. The side wall of the limit block 13 and the convex points 14 are in contact with each other.

[0042] When installing the storage component 4, the sliding block 402 is slidably installed in the movable groove 6, and then the rotating disk 12 and the limit block 13 are rotated to make the limit block 13 and the protrusion 14 on the side wall of the sliding block 402 contact each other, so as to realize the quick installation of the storage component 4.

[0043] In this embodiment, specific reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , a connecting frame 301 is symmetrically arranged on the top of the outer supporting frame 1, a supporting plate 302 is installed above the side where the two connecting frames 301 are close to each other, and a cylinder 303 is symmetrically arranged on the top of the supporting plate 302. The telescopic shafts of the two cylinders 303 penetrate the supporting plate 302 and extend to the bottom of the supporting plate 302. A moving platform 304 is commonly installed at the ends of the telescopic shafts of the two cylinders 303;

[0044] At the four bottom corners of the mobile platform 304, mounting frames 305 are respectively arranged. At the bottom of the inner cavities of the four mounting frames 305, springs 309 are respectively installed. At the sides of the four springs 309 away from the mounting frames 305, pressing blocks 3010 are respectively installed. Between two pressing blocks 3010 parallel to the threaded rod 1104, a positioning plate 306 is installed.

[0045] Among them, as the mobile platform 304 descends, the positioning plate 306 will first contact the plastic film on the top of the working platform 2. As the mobile platform 304 continues to press down, the positioning plate 306 will drive the pressing block 3010 to compress the spring 309 upward. Under the action of the spring 309, the positioning plate 306 will position the cut plastic film to prevent deviation during hot cutting.

[0046] Between two mounting blocks 307, a heating wire 308 is connected. The heating wire 308 is slidably installed in the inner cavity of the scraping ring 1108.

[0047] Among them, the outer wall of the heating wire 308 is in contact with the inner wall of the scraping ring 1108, which is convenient for the scraping ring 1108 to scrape the heating wire 308.

[0048] In this embodiment, specifically refer to Figure 1 and Figure 2 , on one side of the inner cavity of the outer support frame 1 close to the positioning rod 9, two clamping rollers 8 are rotatably arranged. The two clamping rollers 8 are located in the same vertical plane.

[0049] Among them, the two clamping rollers 8 are used for preliminary leveling of the plastic film.

[0050] In this embodiment, specifically refer to Figure 1 and Figure 2 , the moving assembly 7 includes a motor 701. On the top of the working platform 2, the motors 701 are symmetrically arranged. On the power output shafts of the two motors 701, transmission rollers 702 are respectively arranged.

[0051] Among them, the motor 701 drives the transmission roller 702 to rotate, which plays a role in conveying the plastic film. And during the rotation of the transmission roller 702, the plastic film can be leveled for the second time at the same time.

[0052] In this embodiment, specifically refer to Figure 1 and Figure 2 , on one side of the top of the working platform 2 close to the two racks 1101, storage grooves 10 are respectively arranged.

[0053] Among them, the storage grooves 10 are used to store the gears 1102, moving blocks 1105, scraping rings 1108 and mounting blocks 307 at both ends when the hot cutting assembly 3 is working, so that the heating wire 308 can better contact the plastic film.

[0054] When the subject of the utility model of the present scheme is working, firstly, all the electrical equipment in the device are powered on;

[0055] In the first step, the plastic roll to be hot-cut is wound around the outer wall of the positioning rod 9, and then the plastic film is sequentially passed between the two clamping rollers 8, and between the driving roller 702 and the working platform 2;

[0056] After completion, the heating wire 308 is heated, and then the cylinder 303 is started to drive the mobile platform 304 to move downward. As the mobile platform 304 moves downward, the gear 1102 on the connecting shaft 1103 will rotate under the action of the teeth on the rack 1101. When the gear 1102 rotates, it will drive the connecting shaft 1103 and the threaded rod 1104 to rotate synchronously. At this time, the moving block 1105 on the threaded rod 1104 will drive the scraping ring 1108 to scrape the surface of the heating wire 308. The benefit of cleaning the surface of the heating wire 308 solves the problem that the heating wire 308 of the existing device may be adhered to plastic on its surface when it contacts the plastic bag, and the adhered plastic may affect the heat transfer, resulting in uneven heat cutting and affecting product quality.

[0057] The hot-cut plastic film will be transported to the storage box 401 under the action of the transmission roller 702. When the storage box 401 is full, the rotating limit block 13 drives the rotating disk 12 to rotate, so that the limit block 13 does not contact the protrusion 14, and the sliding block 402 at the bottom of the storage box 401 slides out of the movable groove 6, which has the advantage of quickly disassembling the storage component 4 for unloading.

[0058] 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.
