Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to a sealing device used for an intelligent bag filling machine. Background Art

[0002] Patent document CN207208645U discloses a packaging bag sealing device, which includes a conveying component that conveys in a front-to-back direction, a holding mechanism that is driven by the conveying component to hold the packaging bag, and a sealing mechanism arranged at the front of the conveying component. A controller starts a lifting cylinder to lift a holding seat upward to receive a packaging bag from a quantitative weighing device. The packaging bag falls onto the holding seat, triggering a photoelectric sensor. The controller starts a tightening cylinder to clamp the packaging bag with two clamping blocks. At the same time, the controller starts a driving cylinder to move the clamped packaging bag forward with the slide seat. When the packaging bag moves to the sealing mechanism, the photoelectric sensor is triggered, causing the controller to start a clamping plate cylinder to drive two heating clamping plates to clamp the bag mouth of the packaging bag and heat and seal it. At the same time, the controller suppresses the movement of the piston rod of the driving cylinder to allow the packaging bag to stay in the sealing mechanism for a while. After the packaging bag is sealed, the controller controls the two heating clamping plates to open, and at the same time, the driving cylinder continues to drive the slide seat to convey the packaging bag forward, so that the worker can remove the sealed packaging bag. However, after sealing the packaging bag, this sealing device needs to enter the subsequent station to cut the bag, which prolongs the packaging process and is prone to positional displacement during transportation, causing the bag cutting operation position to shift, affecting product quality. Therefore, it is necessary to optimize its structure to overcome the above defects. Utility Model Content
