The principle of PP packaging belt production line:

1. The main and auxiliary machine transmission of PP packing belt production line consists of speed regulating motor, reducer and shaft sleeve. The forming part is composed of screw barrel, head and mouth die. Raw materials are heated and extruded into the screw barrel through hopper to extrude the initial embryo.

2. The water tank of PP packing belt production line is used to cool the primary embryo of the main and auxiliary machine mouth mold. The temperature of the strip head is very high, so it should be cooled in water immediately. Because the isometric polypropylene is easy to generate the brew crystal structure under the condition of quenching, and the crystal molecular structure is relatively loose. Easy to stretch orientation, high quality products

3. The first traction of PP packaging belt production line consists of speed regulating motor, traction roller, reducer and chain drive. It is to transfer the shaped initial embryo to the oven.

4. The secondary heating of the oven under the PP packaging belt production line is easy to stretch; the main purpose of the stretching is to improve the longitudinal strength of the packaging belt and reduce the elongation. The three heating of the oven on the packaging belt production line eliminates the tensile stress, and the upper water tank can eliminate the thermal stress and then set the shape.

5. The drive of the embosser in PP packaging belt production line is that the speed regulating motor is driven by belt, chain and gear to the second traction, to the embossing, and then to the traction.

① The second traction will re stretch the second heated embryo through the pull bar, and then deliver it to the embossing roller;

② After stretching, the packing belt passes two pressure rollers with patterns and is pressed on the pattern. Its function is to increase friction in use, without slipping, and it is beautiful and generous from the appearance. The product surface is embossed by the embossing roller and then transported to the upper water tank or upper oven;

③ The packaging belt production line transmits the forming of the upper water tank to the belt winding machine through the third traction.

6. The drive of the winding machine in PP packaging belt production line is that the speed regulating motor is transmitted to the winding shaft and the travel rod respectively through belt drive and chain drive. It is a single product that takes the qualified product into a specified shape and quality.
