Description

Technical Field

[0001] The utility model relates to the technical field of bag sealing and flanging, in particular to a bag sealing and flanging device. Background Art

[0002] In the production process of sealed bags, in order to improve the stability of the bag opening, it is usually necessary to perform processes such as flanging and hot pressing on the bag body after production to ensure that the bag opening has a certain thickness. This ensures that the sealed bag is not easily damaged by tearing, cracking, etc. during the subsequent process of applying the sealing strip, and also prevents the bag opening from curling.

[0003] In the prior art, flanging wheels are generally used for flanging, such as the patent publication number CN206466254U. The bag flanging device disclosed therein specifically adjusts the inclination angle of the hinge to accommodate bags of different sizes. The position of the flanging wheel is further adjusted by adjusting the extension of the rotating shaft and the extension of the electric push rod, so that the flanging wheel can adapt to various sizes of bags and thus turn up the edge of the bag. However, although the position of the flanging wheel can be adjusted to accommodate bags of different sizes, the size of the edge cannot be accurately controlled, and local folding and misalignment are prone to occur during the flanging process, resulting in inconsistent quality of the bag products.

[0004] Based on the above description, there is an urgent need for a bag flanging device that can accurately flanging the bag. Utility Model Content
