The fixed rod 25 is inserted inside the fixed block 28, and a rubber sleeve 23 is inserted at the bottom end of the moving column 24, and a fixing mechanism is provided on the fixed block 28;

[0038] Through the structural design of the adjustment mechanism, during the packaging process, the film width of the film packaging machine can change with the change of the width of the cosmetic gift box, thereby realizing dynamic adjustment, so as to package cosmetic gift boxes of different widths, and avoid poor packaging effect of some cosmetic gift boxes. When working, the cosmetic gift box is first placed on the conveyor belt 20 and conveyed by the conveyor belt 20. During the conveying process, ensure that one side of the cosmetic gift box is close to the positioning rod 21. When the cosmetic gift box moves to the position of the moving column 24, if the width of the cosmetic gift box just matches the film width initially set by the film packaging machine, the cosmetic gift box will not push the moving column 24 to move when moving on the conveyor belt 20, and the position of the guide frame 22 will not change. If the width of the cosmetic gift box exceeds the film width initially set by the film packaging machine, the cosmetic gift box will abut against the rubber sleeve 23 mounted on the moving column 24, and push the rubber sleeve 23 and the moving column 24 to move to one side. The rubber sleeve 23 can avoid When the movable column 24 abuts against the cosmetic gift box, the side of the cosmetic gift box is deformed. When the movable column 24 moves, the fixed rod 25 will extend from the inside of the fixed block 28. The bottom end of the fixed rod 25 is connected to the abutment rod 26. The abutment rod 26 is inserted into the rotating rod 32 and fits against the inner wall of the movable groove 31. The movement of the abutment rod 26 will push the rotating rod 32 to rotate on the device body 1. The rotating rod 32 is fixed with a gear 35. The two sets of gears 35 are meshed with each other, so the other set of rotating rods 32 will also rotate at the same angle. , and pull the bottom end of the push rod 38, the push rod 38 will pull the guide frame 22 to move, and the connecting spring 42 fixed at the rear end of the guide frame 22 will be stretched. The guide frame 22 is used to fix and guide the film. When the guide frame 22 moves forward, the width of the film covering the cosmetic gift box will increase to facilitate adaptation to cosmetic gift boxes of different widths, wherein the fixed rod 25 passes through the moving column 24 and is fixed to the moving column 24, and both sides of the fixed rod 25 are inserted into the fixed block 28.

[0039] Further, the fixing mechanism includes a top plate 27, which is fixedly connected to the top of the moving column 24, and the top plate 27 is fitted with the top of the fixed block 28.
