Detailed ways

Below in conjunction with accompanying drawing, the utility model is specifically further described. A high-efficiency fully automatic electronic product protective film slitting machine is characterized in that it includes a frame 1, a gear box 2 and a sub-support 3 arranged on it, and two air expansion tubes are arranged between the gear box 2 and the sub-support 3. The shaft 4 and the inflatable shaft 4 can be installed with a parent roll 5 and rotate under the driving action of the gear box 2. A horizontal sliding table 6 is also arranged between the gear box 2 and the sub-support 3, and the sliding table can slide horizontally The slitting knife group 7 is installed on the slitting knife group 7, and the cutting knife 71 is installed on the slitting knife group 7, which can be tangent to the parent volume 5 on the two air-expanding shafts simultaneously.

The inflatable shaft 4 is arranged on the gear box 2 and the sub-support 3 in parallel up and down.

The air-expanding shaft 4 and the auxiliary bracket 3 are installed through the quick-release chuck 31, and the parent roll 5 is installed into the air-expanding shaft 4 through the quick-release chuck 31.

Described cutting knife group 7 comprises being installed on the horizontal slide plate 61 on the horizontal slide table 6, and the vertical slide plate 62 that is installed on the horizontal slide plate 61, and the knife rest 63 is installed on the vertical slide plate 62 and is used for fixing cutting knife 71, and cutting knife 71 rotates at a high speed under the drive of cutting motor 64.

Between the horizontal sliding table 6 and the horizontal sliding plate 61, and between the horizontal sliding plate 61 and the longitudinal sliding plate 62, a servo drive mechanism is arranged, which can drive the corresponding sliding plate to move and realize the feeding action during cutting.
