Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. The terms "horizontal," "vertical," and "suspended," etc., do not indicate that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1-4 As shown, a hot knife fixing structure for a bag making machine includes a fixing base 1 and a hot knife 2, wherein the hot knife 1 is connected to the fixing base 2;

[0025] An insertion slot 101 is provided through the central axis of the long side of the bottom of the fixed base 1. An elongated through hole 102 is provided at the top of the fixed base 1, which is connected to the insertion slot 101. A movable block 3 is provided in the insertion slot 101. A slot 4 is provided on the inner side of the movable block 3. A threaded rod 5 is provided between the slot 4 and the movable block 3. The threaded rod 5 is provided through the movable block 3 and is rotatably connected to the slot 4. To ensure the stability of the threaded rod after rotation, a fixing nut (not shown in the figure) can be provided between the movable block and the slot and on the threaded rod on the outside of the movable block. After the slot is locked, the fixing nuts on both sides of the movable block are further tightened to ensure the stability of the movable block after fixing. Two sets of insertion through holes 1011 are provided from the outside to the inside on the outer surface of the insertion slot 101. A fixing through hole 301 matching the insertion through hole 1011 is provided on the outer surface of the movable block 3 that abuts against the insertion slot 101. The movable block 3 and the insertion slot 101 are fixedly connected by bolts.

[0026] like Figure 2 ,4 As shown, the top of the hot knife 2 is provided with a fixing post 201. The fixing post 201 is led out from the elongated through hole 102 and fixedly connected by a nut 6. After the nut is fixed, the hot knife can be fixed in the vertical direction.

[0027] like Figure 1 , 3 As shown, the inner wall of the insertion groove 101 is provided with limiting grooves 1012 on both sides, and the outer side of the moving block 3 is provided with limiting protrusions 302. The limiting protrusions 302 and the limiting grooves 1012 slide together. The fixed through hole 301 is symmetrically arranged along the central axis of the limiting protrusions 302, and is consistent with the position of the subsequent insertion through hole.

[0028] like Figure 1 As shown, each group of insertion through holes 1011 consists of two holes, which are symmetrically arranged along the central axis of the limiting groove. The position of the insertion through hole is consistent with the position of the fixing through hole to ensure that the bolt can be inserted to fix the moving block.

[0029] like Figure 3 As shown, the outer surfaces on both sides of the slot 4 are provided with slot limiting protrusions 401 that match the limiting slot 1012, ensuring that the slot can move axially, avoiding large displacement, and improving the stability after fixing.

[0030] like Figure 4 As shown, a washer 7 is provided between the nut 6 and the base 1. The washer is used to protect the base and prevent hard contact with the nut.

[0031] like Figure 1 , 3 As shown, the slot 4 has a U-shaped structure. The width of the opening at both ends of the slot 4 gradually increases from the end to the inside. The U-shaped structure can press the two sides of the inserted hot knife body tightly, which can prevent it from axial displacement. At the same time, it can fill the gap between the hot knife body and the insertion slot, further improving stability.

[0032] The working principle of this utility model is explained as follows: In use, first, the hot iron is fixed in the long through hole with bolts. Then, the moving block and the slot are installed and fixed in the insertion slot. Then, the bolts are rotated to push the slot to lock the two sides of the hot iron. When installing a small-sized hot iron, the moving block and the slot are fixed in the inner insertion through hole. The operation is repeated.

[0033] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
