本发明涉及一种用在塑料制袋机上同时形成两个菱形翻角的机构及方法。以往塑料制袋机,多圈塑料薄膜都是同向间歇运动,限制了塑料制袋机生产出的袋型变化。本发明包括前置的导辊对、分切刀片、翻角装置和点焊单元。分切刀片设置在前置的导辊对上方,在前置的导辊对与翻角装置之间设置有点焊单元;翻角装置包括一对导辊、一对模板、一对胶辊、上导辊和后导辊,一对导辊与来料方向
The present invention relates to a mechanism and method for forming two rhombohedral angles simultaneously on a plastic bag making machine. In the past, plastic bag making machine and multi-turn plastic film all moved in the same direction and intermittently, which restricted the change of bag type produced by plastic bag making machine. The present invention includes a front pair of guide rollers, a slitter blade, a cornering device, and a spot welding unit. The cutting blade is arranged above the front guide roller pair, a spot welding unit is arranged between the front guide roller pair and the cornering device; the cornering device comprises a pair of guide rollers, a pair of templates, a pair of rubber rollers, Guide rollers and guide rollers, a pair of guide rollers and incoming direction
