The active roller and the driven roller are symmetrically arranged on the inner side of the first U-shaped frame, and one end of the active roller is connected to the drive motor through a motor shaft.

[0004] Although the above-mentioned prior art solutions can remove dust, moisture, and sterilize the meltblown cloth by setting a traction component, which is beneficial to the production quality of the mask, the existing polypropylene meltblown cloth needs to be edge-sealed when it is made into a filter bag. However, after the meltblown cloth is folded in half, the folding line retains the original memory, causing the edges to be unable to align, thereby bulging, making it inconvenient to perform edge sealing, and the edge sealing loading and unloading process of some equipment is time-consuming and cannot achieve simultaneous loading and unloading and edge sealing.

[0005] In view of this, we propose a polypropylene meltblown fabric edge sealing device. Utility Model Content
