[0015] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0016] As Figure 1 Shown in a kind of plastic film production with setting machine, including fuselage 1, fuselage 1 is long type, and hot setting assembly and cold setting assembly are installed along length direction, and hot setting assembly and cold setting assembly are arranged in layers from top to bottom, and hot setting assembly is located above cold setting assembly.
[0017] The heat setting assembly comprises a hot air blower 2 mounted above the machine body 1 and a reversing roller 3 mounted on the top surface of the machine body 1, the two ends of the reversing roller 3 are mounted on the machine body 1 through bearing seats 4, and the hot air blower 2 is fixed on the machine body 1 through a support 5. The bottom of the machine body 1 is provided with a supporting leg 6. The bottom surface of the hot air blower 2 is provided with a hot air outlet corresponding to the reversing roller 3, so that the hot air blower 2 directly blows hot air to the reversing roller 3, the hot air heats the plastic film on the reversing roller 3 to eliminate the tension and stress of the film and make the film properties uniform. The blowing temperature is adjusted by the temperature control system of the hot air blower 2.
[0018] The cold setting assembly comprises a water-cooled roller 7, the two ends of the water-cooled roller 7 are rotatably connected to the machine body 1 through bearings. The end of the water-cooled roller 7 is connected to a water inlet pipe 8, the water inlet pipe 8 is connected to a cold water source, and a valve switch is installed on the water inlet pipe 8 corresponding to each water-cooled roller 7. The heated and set plastic film is cooled and set by the water-cooled roller 7.
[0019] As shown in Figure 2 , the reversing roller 3 is a plurality of, the plurality of reversing rollers 3 are installed in parallel on the machine body 1, the hot air outlet of the hot air blower 2 is a plurality of, the hot air outlet corresponds to the reversing roller 3 one by one; the water-cooled roller 7 is a plurality of, one water-cooled roller 7 is installed between adjacent two reversing rollers 3. From the inlet to the outlet of the machine body 1, the plastic film first contacts the reversing roller 3 and then contacts the water-cooled roller 7, and leaves from the water-cooled roller 7, during which the plastic film passes through the hot roller and the cold roller for multiple times, so that the plastic film is fully set.
[0020] In order to facilitate the plastic film to contact the reversing roller 3 when entering, a guide roller 9 is rotatably connected to the inlet side of the machine body 1, the guide roller 9 is located in front of the reversing roller 3, and the plastic film is guided by the guide roller 9 and passes over the reversing roller 3.
[0021] When the plastic film is wound on the water-cooled roller 7 after leaving the reversing roller 3, the water-cooled roller 7 for one-time cooling can be one, the plastic film passes below the water-cooled roller 7 after cooling and then extends upward to the next reversing roller 3. In other embodiments, during the one-time cooling process, the upper and lower two oppositely rotating water-cooled rollers 7 constitute a cold roller group, one cold roller group is arranged between adjacent two reversing rollers 3, and the plastic film passes between the two water-cooled rollers 7 after leaving the reversing roller 3, and is cooled by the two water-cooled rollers 7, and then extends upward to the next reversing roller 3.
