Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag sealing devices, in particular to a packaging bag sealing structure for adjusting a sealing width. Background Art

[0002] Since the food or items in the packaging bag often take some time to be eaten or used up, the packaging bag needs to be stored for a while after opening. In order to avoid dust accumulation on the items in the bag and to make the opened packaging bag easier to place, a packaging bag sealing device is needed to seal the packaging bag.

[0003] Most of the existing sealing devices are large-scale machines, which are inconvenient to use in families or supermarkets, and are expensive. Based on these problems, Chinese patent CN207595411U discloses a packaging bag sealing device. A crank slider mechanism is formed between the driving wheel, the connecting rod and the punching needle row, with the driving wheel as the crank, the connecting rod as the connecting rod and the punching needle row as the slider, so as to realize the mutual conversion between rotation and movement. The packaging bag is finally sealed by the rotation of the driving wheel. The rotation of the driving wheel can be achieved by hand crank or motor drive, which is simple and fast. The matching relationship between the punching needle row and the discharge channel can not only protect the punching needle row from damage, but also has stable operation, and the generated debris can be discharged in time.

[0004] The sealing widths corresponding to packaging bags of different sizes are also different. Since the length of the needle row in the device is fixed, packaging bags of different sizes cannot be sealed quickly. At the same time, the packaging bag placement platform in the sealing device lacks a limiting mechanism, so the packaging bags placed on the platform are prone to deviation, which seriously affects the use efficiency of the sealing device.
