Detailed ways

The implementation of the present utility model is illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

The utility model provides a pre-folding device for strip-wrapped transparent paper, as shown in Fig. 1 . The transparent paper pre-folding device for strips includes a folding plate 1 and fixed folding blocks 2 fixed at both ends of the folding plate 1. The inner side of the fixed folding block 2 is provided with a dovetail groove 6 along its height direction, and slides in the dovetail groove 6. There is a movable folding block 8; the inner surface of the head end of the movable folding block 8 is provided with lines 7, and the lines 7 are consistent with its sliding direction, and the setting of the lines 7 can reduce the contact between the movable folding block 8 and the transparent paper during the folding process , thereby reducing the abrasion of transparent paper.
