A kind of folding method of electric blanket

Abstract

The invention provides a folding method of an electric blanket. Creases of the electric blanket are inclined creases and are shallow through the folding method. The folding method comprises the specific steps that a, a first crease line AB, a second crease line I-section CD and a second crease line II-section EF are positioned on the electric blanket; b, a complete second crease line CFDE with part of areas overlapped is formed by the second crease line I-section CD and the second crease line II-section EF of the electric blanket folded along the first crease line AB; c, the electric blanket is folded along the second crease line CFDE, and then the electric blanket is divided into two symmetrical parts with the perpendicular bisector GH perpendicular to the first crease line AB as the center line; d, the two parts of the electric blanket obtained in the above step are each divided into three equidistant parts by two crease lines, and the crease lines are parallel to the perpendicular bisector GH; and e, the two sides of the perpendicular bisector GH are folded in the sequence of the crease lines from outside to inside, so that the two sides of the perpendicular bisector GH form two independent rectangular areas, and then the electric blanket is oppositely folded according to the perpendicular bisector GH to form a small rectangle.

Description

technical field [0001] The invention relates to the technical field of electric blanket packaging, in particular to a folding method for the electric blanket. Background technique [0002] The electric blanket is a kind of contact electric heating appliance. It weaves or sews a special cable-type electric heating element with a standard insulation performance into the blanket in the shape of a snake, and it emits heat when it is energized. It is mainly used to increase the temperature in the quilt when people sleep to achieve the purpose of heating. Existing electric blankets generally have a rectangular structure after being unfolded, and the heating wires inside are generally arranged in a parallel winding structure. When packaging, the unfolded rectangular electric blanket is folded in half to form a small rectangular structure, and then put into the packaging box Inside, since the heating wire is generally arranged parallel to the outside of the electric blanket, the fo...

Problems solved by technology

Existing electric blankets generally have a rectangular structure after being unfolded, and the heating wires inside are generally arranged in a parallel winding structure. When packaging, the unfolded rectangular electric blanket is folded in half to form a small rectangular structure, and then put into the packaging box Inside, since the heating wire is generally arranged parallel to the outside of the electric blanket, the folding angle of the corresponding folding part of the heating wire is 0° during the folding process, and the folded crease is short and hard folded, causing the heating wire to overlap each other , during the packaging and transportation process, the heating wire will be irreversibly damaged, and because the electric blanket is a seasonal commodity, it needs to be folded and stored again every year. This folding method makes the electric blanket generally use for five years, and the heating wire will be damaged, and then The electric blanket cannot be used normally, which makes the service life of the electric blanket short
