Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-3, an apparatus for manufacturing a PE film easy-to-tear line comprises an unwinding roller 1, a winding roller 4 and a cutting roller 3, wherein the height of the cutting roller 3 is higher than the heights of the unwinding roller 1 and the winding roller 4, under the matching of the unwinding roller 1, the winding roller 4 and the cutting roller 3, the PE film is in a tightening state, the cutting roller 3 is positioned between the unwinding roller 1 and the winding roller 4, the cutting roller 3 is a hollow cylinder, a cutting knife 36 and an electric telescopic rod 33 are arranged inside the cutting roller 3, the cutting knife 36 is composed of a plurality of blades, the blades are evenly distributed in the crack of the fixing plate 37, a sliding chute for the blades to slide is formed in the fixing plate 37, the lower surface of the fixing plate 37 is fixedly connected with the telescopic end of the telescopic rod 33, the other end of the telescopic rod 33 is fixed on the inner surface of the cutting roller 3, a through hole 31 matched with the blades is formed in the periphery of the cutting roller 3, and the telescopic rod 33 can drive the fixing plate 37 to move up and down to achieve the stretching of the cutter 36 in the cutting roller 3.
It should be noted here that the length between adjacent tear lines is a multiple of the circumferential length of the cutting roll 3, and the specific multiple is determined according to the length of a single PE film.
The number of the telescopic rods 33 is at least two and is uniformly distributed on the lower surface of the fixing plate 37.
The two sides of the cutting roller 3 are also provided with pressing rollers 2, the height of each pressing roller 2 is slightly lower than that of the cutting roller 3, the pressing rollers 2 on the two sides are respectively abutted to the cutting roller 3, and the cutter 36 is convenient to form an easy-to-tear line.
