Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to an automatic docking device. Background Art

[0002] After the traditional packaging machine is automatically connected, the new and old packaging films are bonded with double-sided tape. The two layers of packaging film plus a layer of double-sided tape are relatively thick, which has an adverse effect on subsequent transportation and heat stitching. When the machine automatically aligns and connects, the double-sided tape will leak out due to the inaccurate alignment of the new and old films. In the subsequent transportation process, sticking, pulling, and entanglement will occur, affecting the normal operation of the equipment. There are unbonded parts at both ends of the tape. Since the packaging film is unrolled, the unbonded parts will roll up by themselves, affecting the subsequent feeding into the bag maker, causing unstable bag making, and the risk of the packaging film being torn.
