Background
The fruit net cover refers to a foamed plastic net cover, also called EPE pearl cotton, which is a material obtained by melting and extruding LDPE resin as a main raw material and performing decompression foaming. Has the advantages of shock absorption, high toughness, stable chemical property and the like. Therefore, the fruit packaging bag is widely applied to the fruit packaging industry. The weight of the net is very light, and the friction coefficient between the net and other materials is very large. The net cover will be stacked in a scattered manner when placed in a large number, and it is very difficult to separate the net cover individually and to make the net cover have a fixed posture. However, most of the existing fruit net covers adopt a manual sleeving mode to sleeve the net cover on the fruit. The fruit net cover is a net cylindrical structure formed by interlacing net wires, and is of a flaky double-layer structure when not used, and fruits are put in the fruit net cover after being spread when the fruit net cover is used. Due to the characteristics of the material of the net sleeve, no practical machine can quickly and effectively prop up the net sleeve cut into a certain size, so that fruits can be placed into the net sleeve in the follow-up process; therefore, the device for continuously opening the fruit net cover is designed, and the problem to be solved by the technical personnel in the field is solved.
