Straightener for punching holes in plastic bags

Abstract

The invention discloses a leveling machine for punching plastic bags. The leveling machine for punching the plastic bags comprises negative pressure stabilizers, a proofreading ruler and a tensioningframe, wherein the proofreading ruler and the tensioning frame are perpendicular to each other to form an L-shaped framework, the inner angle of the proofreading ruler and the inner angle of the tensioning frame are right angles, the outer angle of the proofreading ruler and the outer angle of the tensioning frame are arc angles, the length of the proofreading ruler is longer than that of the tensioning frame, the negative pressure stabilizers are vertically installed at the head and tail ends and turning points of the L-shaped framework, and the negative pressure stabilizers are composed of backing plates, thread ends, chains, cylinder paths, plug heads and sucking discs. The backing plates are fixed to the upper surface of the tensioning frame or the proofreading ruler, and the cylinderpaths are formed in the tensioning frame or the proofreading ruler relative to the backing plates. Through the cooperation of the negative pressure stabilizers, the proofreading ruler and the tensioning frame, it is guaranteed that hanging holes of the front and rear batches of specification plastic bags are at the same position, the storage space is moderate, the plastic bags are not prone to overturning during storage and transportation, and the plastic bags are irregular during hanging.

Description

technical field [0001] The invention relates to the field of plastic bag punchers, in particular to an aligner for punching plastic bags. Background technique [0002] Ordinary plastic bags need to be punched for hanging, and half of them are punched by a punching machine. The punching position for hanging is only in the middle of the two handles of the plastic bag. The plastic bags are stacked (with certain thickness) for punching, but the current punching machine is not equipped with a straightener, the hanging holes of the front and rear batches of plastic bags after punching are not in the same position, that is, the protrusions caused by punching are not in the same position, which will not only increase Large storage space, at the same time, it is prone to tipping during storage and transportation, and it will be uneven when hanging in plastic bags. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention is realized thro...
