[0020] First of all, the original intention of the design of the present invention is explained. The existing square packaging box wrapping methods are generally divided into manual wrapping and automatic wrapping by equipment, and heat shrink film wrapping is usually used. Manual wrapping has been gradually replaced by equipment wrapping due to its low efficiency and poor precision. Currently common wrapping heat shrinking machines include cuff machines, L-shaped packaging machines, etc. The existing automatic wrapping equipment usually adopts bottom-sealing heat shrink wrapping machines. Bottom-sealing heat shrink wrapping machines are used for various product packaging boxes. They are mainly for performing four-corner chamfering process on the outer packaging of various square product boxes to improve the appearance. Since the square box needs to be fully wrapped, the existing automatic wrapping equipment has complicated procedures, low wrapping efficiency, and low wrapping precision, which cannot meet the requirements of production efficiency and quality. Therefore, a top film sorting mechanism is needed to improve the quality and efficiency of square box wrapping.

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1-Figure 3 As shown, a top film arrangement mechanism includes a main fixed plate 1. In order to fix the square box, a lifting control component 2 is needed. In order to determine the position of the square box, a synchronous reverse servo motion module 4 is needed. In order to facilitate the installation of the synchronous reverse servo motion module 4, a lifting and movable module fixing plate 3 is arranged at the bottom of the main fixed plate 1, and the synchronous reverse servo motion module 4 is installed at the bottom of the module fixing plate 3.

[0022] The lifting control component 2 is fixed on the main fixed plate 1. A plurality of mounting holes 10 are provided on the main fixed plate 1. In order to ensure that the lifting control component 2 is lifted vertically, a connecting bushing 11 is installed in each mounting hole 10. The specific structure of the lifting control component 2 will be introduced in detail below. The lifting control component includes a lifting guide column 12 arranged in the connecting bushing 11. The bottom end of the lifting guide column 12 is fixedly connected to the module fixed plate 3. A mounting top plate 13 is arranged on the top of the plurality of lifting guide columns 12. A servo motor 14 is installed on the mounting top plate 13. The output end of the servo motor 14 is connected to a lifting screw rod 16 through a coupling 15. A fixing nut 17 is provided on the lifting screw rod 16. The lifting screw rod 16 is fixedly connected to the module fixed plate 3 at one end away from the servo motor 14. The fixing nut 17 is fixed at the center position of the main fixed plate 1. The lifting screw rod 16 is further driven by the servo motor 14 to drive the module fixed plate 3 up and down.

[0023] In order to fix the two sides of the top of the square box, a step-by-step synchronous lever mechanism 7 is also needed. The synchronous lever mechanism is installed at the bottom moving end of the synchronous reverse servo motion module 4. In order to facilitate the installation of the step-by-step synchronous lever mechanism 7, an auxiliary fixing plate 5 is provided at the bottom moving end of the synchronous reverse servo motion module 4. A mounting vertical plate 6 is vertically provided at the bottom of the auxiliary fixing plate 5, and the step-by-step synchronous lever mechanism 7 is installed on the mounting vertical plate 6.

[0025] In order to facilitate adapting to square boxes of different sizes, two adjusting nuts 24 are provided, namely a left-handed nut 241 and a right-handed nut 242. A forward and reverse screw 25 is installed in the adjusting nut 24. In order to drive the rotation of the forward and reverse screw 25, a second pulley 26 is provided at one end of the forward and reverse screw 25. The first pulley 20 and the second pulley 26 are connected by a connecting belt 27. The forward and reverse screw 25 is driven by the power motor 19 and driven by the second pulley 26 to rotate. The forward and reverse screw 25 rotates, so that the left-handed nut 241 and the right-handed nut 242 move in relative or opposite directions, and then the side inserts 29 of different sizes can be replaced.
