AI Technical Summary
Traditional ton bag sealing devices suffer from slow sealing speed and weak sealing, mainly because the sealing components move slowly and it is difficult to maintain uniform pressure at each sealing point of the ton bag.
The sealing mechanism is driven by a cylinder, combined with a buffer and a guide shaft. The buffer converts part of the thrust into deformation when the sealing mechanism approaches the ton bag, so as to achieve stable and uniform clamping of the sealing mechanism. The deceleration time of the sealing mechanism can be quickly adjusted by adjusting rod and clamping block structure. It works with silicone strip and heating strip to achieve efficient sealing.
It improves sealing speed and stability of sealing effect, ensures uniform pressure on each sealing point of the ton bag by the sealing component, improves sealing efficiency and firmness, and supports quick replacement of consumable parts, thus improving ease of use.
