[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. Their materials and prices are different, so people have very high requirements for its appearance, such as whether there are wrinkles, bubbles, and whether the appearance is flat, so a plastic woven bag flattening machine is needed.

[0003] According to the description of a plastic woven bag flattening machine disclosed in the patent website (authorization announcement number: CN 219927104U), "The utility model discloses a plastic woven bag flattening machine, which relates to the field of flattening machines. The plastic woven bag flattening machine includes a flattening machine body, on which a conveyor belt, two connecting plates and a clamping mechanism are provided, one of the connecting plates is provided with a motor, a pressing roller is provided between the two connecting plates, and the clamping mechanism includes two fixed plates, on which a clamping rod is provided, and the two fixed plates are fixedly connected by a cross brace. The plastic woven bag flattening machine rotates the screw rod so that the screw rod drives the cross rod to move up and down, thereby causing the clamping rod to move up and down, and utilizes the elastic force of the telescopic spring to squeeze and clamp the plastic woven bag between the clamping rod and the conveyor belt, so that the wrinkles on the surface of the plastic woven bag and the air inside the bag are removed, and then the plastic woven bag is flattened by the friction between the conveyor belt and the pressing roller."

[0004] In view of the above description, the applicant believes that there are the following problems:
