AI Technical Summary
The existing manual pressure cutter for laminated paper suffers from uneven force on the cut area, resulting in inaccurate cutting position and the inability of the pressure cutter to automatically reset when the hand is holding it, thus affecting cutting efficiency.
A structure comprising a flat plate, support strips, bottom side plate, lower pressure clamp, and upper pressure clamp is designed. Through the cooperation of a strong tension spring and a side push wedge, the laminated paper is clamped and positioned. By adjusting the outer sleeve and the reset tension spring, the automatic reset and manual adjustment of the hand-cutting guillotine are achieved.
It achieves accurate positioning of the laminated paper during cutting, avoids warping, improves cutting accuracy and efficiency, and the hand-cutting guillotine can automatically reset, making operation smoother.
