Document Type and Number:
WIPO Patent Application WO/2020/088471
Kind Code:
A1
Abstract:
Disclosed are a width-adjustable packaging bag forming device, a bag making device, a packaging machine and a method. The forming device (II-1) comprises two parts which are symmetrically arranged, with the width between the two parts being adjustable, wherein the middle part serves as a guide surface; two sides of the guide surface are side wings bending towards the middle part; and the parts exceeding the guide surface of the side wings in length are bent towards a back side of the guide surface to form rear inclined angles. The invention can achieve the effect that when a packaging film (I-5) passes by same, the packaging film (I-5) starts to bend back inwards at a certain angle. A screw rod and sliding block mechanism is used as a width adjusting device of an automatic width-adjustable noodle packaging bag forming device system, has an accurate adjustment range, is suitable for various widths of packaging bags, and is of great significance for the three-dimensional forming effect of packaging bags.
