Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag production, in particular to a flattening device for plastic bag production and processing. Background Art

[0002] Plastic bags are indispensable items in people's daily lives and are often used to hold other items. They are widely used because of their advantages of being cheap, extremely light, large in capacity, and easy to store. However, they are banned from use and production in some countries because of their extremely long degradation cycle and difficult handling. In particular, the white square plastic bags used in supermarkets require many processes in production. In the prior art, announcement number CN219947467U discloses a leveling device for plastic bag production and processing. When this device is used, the surface of the plastic bag is initially leveled with the help of a leveling plate so that it has no warping corners. Then, through the transmission action of two pulleys and a belt, the leveling roller performs secondary leveling on the plastic bag. However, the leveling roller in this device is not easy to adjust in height. When the plastic bag to be leveled is thicker, the staff adjusts the height of the leveling roller at a slow rate.
