[0014] Beneficial effects of the utility model:

[0015] 1. PE automatic loading and unloading PE film cutting structure inserts the PE film structure into the plug-in shaft and is attracted by the magnet. The dynamic coil structure rotates to pack the braid and material roll. After the material roll is in place, the braid automatically extends the upper belt structure to clamp the belt. The dynamic coil rotates clockwise to pack. At the same time, the braid is over-wound. The dynamic coil pauses after a certain number of turns. The upper belt structure loosens and moves to the cutting structure side to clamp. The cutting structure cuts the braid, and the dynamic coil continues to rotate. When there is any braid left, the dynamic coil pauses. The PE film structure is inserted into the plug-in shaft again and is attracted by the magnet. The dynamic coil rotates to complete the PE wrapping of the braid tail. After a certain number of turns or length, the PE film is cut and the material is unloaded.

[0016] 2. When there is no packaging, the opening of the PE film is clamped by the clamping plate and the second clamping block. After the braided belt is packaged, the first cylinder pushes the relevant components forward and inserts the PE film into the insertion shaft. The fourth cylinder releases the PE film and the first cylinder retracts. When the moving coil rotates, the third cylinder extends the blocking shaft. After a few turns, the second cylinder pushes to release the PE film (the first clamping block is blocked by the blocking shaft). Later, the second cylinder is retracted and the blocking shaft is also retracted. When the rotation is almost over, the second cylinder extends again and the PE film falls to the hook-back shaft. After the packaging is completed, the first cylinder extends, the fourth cylinder clamps the PE film, and the second cylinder retracts the components and PE film. The PE film touches the hot knife and breaks off, and one end is re-clamped. The first cylinder retracts the clamped PE film, and the sensor confirms that the fourth cylinder has successfully clamped the film. BRIEF DESCRIPTION OF THE DRAWINGS
