Description

technical field [0001] The invention relates to the technical field of automatic processing of cup sleeves, in particular to an automatic forming equipment for pearl cotton heat-insulating cup sleeves. Background technique [0002] When the cup is in use, it is necessary to put a layer of cup sleeves on the outside of the cup, such as water cups, coffee cup sleeves, or milk tea cup sleeves, to play the role of heat insulation and anti-scalding. At present, the mainstream in the market is still made of kraft paper or other paper materials, but the heat insulation effect of the cup sleeve made of kraft paper is not good enough, the manufacturing cost is high, and it is not environmentally friendly. [0003] Therefore, someone has developed a pearl cotton composite material to replace kraft paper to make cup sleeves. The pearl cotton composite material includes pearl cotton and a surface layer with patterns, logos and / or text. Pearl cotton is produced by physical foaming of low...

Problems solved by technology

[0004] Making cup sleeves with pearl cotton composite materials includes the following processes, as attached Figure 8-9 As shown, firstly, the pearl cotton composite material should be cut into Figure 8 The arc shown, and then iron off the pearl cotton at one end of the arc, then apply glue to the part where the pearl cotton was ironed off, and finally roll it into a shape as attached Figure 9 In the shape of the cup sleeve shown, the end is bonded by glue, and the adhesive strength between the surface layer and the surface layer is higher, and it is not easy to fall off. However, there is no such process on the market at present, and there is no similar automatic molding equipment. Relying on manual production of pearl cotton heat insulation cup sleeves, the efficiency is low
