However, the size of the package can vary and the opening can be larger or smaller due to a number of factors. When the opening is less than normal, open the bag board and can't open effective angle, can make the film take off the bag board easily for the product is pushing the in-process of wrapping bag, and the wrapping bag also can take off the bag board gradually, causes the change of product position in the wrapping bag, makes to seal the back, causes to seal defect or pattern nonstandard, forms the waste product. When the opening is on the large side, the opening angle of the bag opening plate is generally 90 degrees, which is beneficial to the entering of the product, so that the effective support of the bag body can not be realized, the product can be pushed into the packaging bag, the packaging bag can be gradually separated from the bag plate, the position of the product in the packaging bag is changed, and after the opening is sealed, the defects or patterns of the sealing are not standard, and waste products are formed. The problem can be well solved by arranging the clamping mechanism, the clamping driving device and the flexible clamping part. The bag body is arranged, so that the small-pocket mask is more convenient to use. The setting of ironing pressing flattening can be so that the plane nature of gauze mask is better, and thickness, the roughness after folding are better.
