[0002] Stretch film, also known as wrapping film, is an industrial packaging product with strong tensile force, strong extensibility, good retraction, good self-adhesion, thin texture, softness, high transparency, etc. It can be used as hand-held stretch film or machine-held stretch film, and can be widely used in the packaging of various goods. Stretch film has strong puncture resistance and super tensile properties. After wrapping the goods, it makes the goods more stable, firm and neat, and has a particularly good waterproof effect. It is widely used in various industries.

The rotating threaded rod 701 pushes the second roller 8 to move left and right, thereby playing a role in stretching the diaphragm more comprehensively. The outer sides of every two motors 4 are covered with a shell 401.

[0022] like Figure 3As shown, it also includes a connecting plate 301, a first mounting plate 302, a first guide rod 303, a first spring 304, a second spring 305, a wedge block 306 and a second guide rod 307.

[0023] The diaphragm to be stretched is put in from one side of the frame 1, and the motor 4 drives the first roller 2 to rotate, and the first roller 2 pushes the diaphragm to move. After the diaphragm moves to the middle of the frame 1, the motor 4 stops working and pushes the wedge block 306 outward, and the wedge block 306 moves along the first guide rod 303, and the wedge block 306 is disengaged from the connecting plate 301. The connecting plate 301 moves downward along the second guide rod 307 under the action of the restoring elastic force of the second spring 305, and moves downward with the pressing roller 3 to press the diaphragm, and the cylinder 6 works to lift the mounting frame 5 upward, and the second roller 8 pushes the diaphragm upward to push the diaphragm to stretch, and the motor 7 works to drive the transmission assembly 702 to rotate, and the transmission assembly 702 drives the threaded rod 701 to rotate, and the fixed plate 801 threadedly connected to the threaded rod 701 moves back and forth with the second roller 8 to lift the diaphragm at various parts, and the extension and retraction length of the cylinder 6 is controlled as needed to play a stretching role.
