[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. By setting up a snap-fit ​​guide device for tape die-cutting, which is composed of a rotating shaft, a positioning seat, and a top holding seat, and by setting a movable column on the inner side of the positioning seat and allowing the movable column to be movably installed in the movable hole, and embedding a magnet in the inner side wall of the positioning seat, and by casting the rotating shaft with ferromagnetic material, the movement of the top holding seat controls the outward movement of the positioning seats on both sides of the cutting point, thereby ensuring the positioning stability of the aluminum foil tape roll. Furthermore, the gap value between adjacent groups of positioning seats is greater than the thickness value of the blade on the cutting mechanism, which can form a clearance groove to ensure that the aluminum foil tape roll is completely cut, avoiding the phenomenon of tangled threads, and avoiding contact between the blade and the rotating shaft to prevent wear, thereby ensuring the service life of the blade.

[0031] 2. An air chamber is opened on the top support and connecting rod, a primary air channel is opened on the movable column, and an adsorption chamber is opened on the outer wall of the positioning seat. The operation of the air extraction device creates a negative pressure in the adsorption chamber, thereby further improving the positioning stability of the aluminum foil tape roll.
