Winding membrane stretching device

Abstract

The invention relates to a winding membrane stretching device. The winding membrane stretching device comprises an unwinding shaft, a plurality of supporting shafts and a winding shaft, wherein the supporting shafts are arranged in a high-low staggered manner at intervals; a hot air blower is arranged above one high-position supporting shaft; and the rotating speed of the unwinding shaft is smaller than the rotating speed of the winding shaft. A total of eight supporting shafts are arranged on the winding membrane stretching device, and the hot air blower is arranged above the third supporting shaft, namely the high-position supporting shaft. The rotating speed of the unwinding shaft is one third of the rotating speed of the winding shaft. Position adjustment of the fifth supporting shaft and the seventh supporting shaft of the winding membrane stretching device can be done in the horizontal direction, and the other supporting shafts are fixed. The temperature of the hot air blower of the winding membrane stretching device ranges from 40 DEG C to 70 DEG C. After being stretched by the winding membrane stretching device, a winding membrane becomes thin and is elongated to form a thin type membrane roll, the length of the membrane roll is two times larger than that of an original membrane roll, and the manually-packaged cargo quantity is increased; and compared with a traditional winding membrane, when same cargoes are packaged, the using number of the winding membrane is fewer, and the packaging cost is low.

Description

technical field [0001] The invention relates to a stretching device, in particular to a stretching film stretching device in a film production workshop. Background technique [0002] There are two types of stretch film for organic use and hand use. The machine use film is packaged by machine, and the hand use is manual packaging. When the machine packs, the stretch film is stretched by the machine to a certain proportion and then wrapped on the goods. Due to the small stretching force of the hand, the stretch film is only slightly stretched, and the stretch film cannot be stretched to the maximum. Stretch film of the same specification adopts different packaging methods. Relatively speaking, the cost of manual packaging is higher than that of machine packaging, because it consumes more stretch film. Contents of the invention [0003] The purpose of the present invention is to provide a stretching film stretching device, which can maximize the stretching and thinning of th...
