Technical Field
[0001] This utility model relates to the field of packaging machine technology, specifically to a box self-winding packaging machine. Background Technology
[0002] Fully automatic stretch wrapping machines are machines used to package goods. They are widely used in the packaging of products such as foreign trade exports, food and beverages, plastics and chemicals, glass and ceramics, and electromechanical castings. They can prevent damage to goods during handling and play a role in dust prevention, moisture prevention, and cleanliness.
[0003] For example, utility model patent CN218617319U discloses a fully automatic wrapping machine with multi-row film feeding, including a box body. A wrapping mechanism is provided on the top of the box body. A bottom plate is fixed on the upper surface of the box body. A vertical plate is vertically fixed on the upper surface of the bottom plate. A top plate is vertically fixed at the top of the vertical plate. A fixing block is rotatably connected to the lower surface of the top plate through a bearing. An electric push rod is fixed on the lower surface of the fixing block. A pressure plate is fixed on the outside of the output shaft of the electric push rod. A support plate is horizontally provided above the bottom plate. The wrapping mechanism includes a dual-axis motor fixed to the top wall of the inner cavity of the box body. This fully automatic wrapping machine with multi-column film feeding drives the upper output shaft of a dual-axis motor to rotate the object, and drives the lower output shaft of the dual-axis motor to make the two movable sleeves move horizontally to opposite sides, so that the top and bottom of the object to be packaged start wrapping simultaneously, thereby improving the packaging efficiency. However, there is a problem that after the film is wrapped around the object, it is inconvenient to cut, which requires manual cutting of the film and ultimately reduces the efficiency of wrapping the object. To address this, we propose a self-wrapping box packaging machine. Utility Model Content

The output of the electric push rod drives a double rack to move forward, which in turn drives the main cutter. The rack then drives a follower gear to rotate, which in turn drives a second follower shaft to rotate, thereby causing the secondary cutter to pull the film apart at both ends.
