Description of the drawings:

fig. 1 is a schematic view of the structure relating to the present invention.

The specific implementation mode is as follows:

the invention will be further described with reference to the accompanying drawings.

The invention relates to a folding mechanism of a full-automatic N95 mask machine, which mainly comprises a conveying mechanism 1, an ear band welding device, a folding mechanism and a splitting mechanism 8, wherein the conveying mechanism 1 is butted with the folding mechanism, the conveying mechanism 1 conveys a cloth band formed by compounding a plurality of kinds of cloth, the cloth band passes through the ear band welding device, the folding mechanism and the splitting mechanism 8 to finish discharging and returning, and the parts are the prior art and are not described in detail herein.

Doubling mechanism includes the downward sloping and is the interior shaping body 2 of tunnel form, and is located the shaping body 3 of interior shaping body 2 top, at the descending in-process of strap, interior shaping body 2 makes the gauze mask both sides draw close gradually with shaping body 3, accomplish the fifty percent discount at last, utilize descending doubling mechanism, after conveying mechanism 1 carries the strap parallel and accomplishes the ear area welding, can directly get into the doubling mechanism down, compare in the doubling mechanism that moves upward, strap inertial resistance is littleer, therefore need not the transition, can directly carry out the fifty percent discount shaping down after the ear area welding, it is preferred, set up the compression roller in conveying mechanism 1 end top, can make the strap both sides exhibition flat.

2 lower part both sides of interior shaping body are provided with air jet system 4, and 2 both sides of interior shaping body dispose ear area folded sheet 5, and air jet system 4 is located the position of punching of interior shaping body 2 and spouts the air current outside, specifically sets up two air jet system 4, can be when the strap is down, and the ear area is flagging, and is outwards raised to the side when the air jet system 4, and the ear area can be in the strap in-process down like this, and attached in the outside of ear area folded sheet 5, can further utilize ear area folded sheet 5's structure to go up the book.

Specifically, the shaping body 3 is wrapped in the inner shaping body 2, the shaping body 3 covers two sides of the upper portion of the front half section of the inner shaping body 2, the ear band folding plates 5 cover two sides of the lower portion of the front half section of the shaping body 3, and the ear band folding plates 5 cover two sides of the rear half section of the inner shaping body 2. When the strap is down, in the first half section of interior shaping body 2, the strap preferentially passes between interior shaping body 2 and the shaping body 3, after 4 air jet system, the ear area is perpendicular to the surface of ear area folded sheet 5, then get into interior shaping body 2 back half sections gradually, at this moment ear area folded sheet 5 crescent cover face, then the ear area is done to roll over by the direction of ear area folded sheet 5, and after last book, the strap is in the fifty percent discount and the ear area is rolled over at the gauze mask of this position, and the shaping body 3 of this position only covers in interior shaping body 2 top, therefore whole gauze mask is in between interior shaping body 2 and ear area folded sheet 5, until leaving interior shaping body 2.

The plastic body 3 is provided with a plurality of rolling wheels 31 along the upper side of the inner molded body 2, and the folding lines are gradually compressed in the process of being gradually folded in half, so that the rolling surfaces (i.e., the width of the rolling wheels) of the rolling wheels 31 are gradually reduced from the beginning to the end of the inner molded body 2.

In order to supply certain pulling force of strap, and accomplish the last complete attachability fifty percent discount to the strap that leaves interior shaping body 2, then dispose vertical compress roller 6 of arranging between fifty percent discount mechanism and the slitting mechanism 8, compress roller 6 comprises two vertical compression rollers of arranging about by, in the strap of compress roller 6, the inboard of gauze mask is the fifty percent discount form of pasting together completely to, the ear area is the form of folding up of pasting in the gauze mask outside.

Further, ear area 5 latter half both sides all are provided with windowing position 51, windowing position 51 outside is provided with rubberizing mechanism 7, mainly be after ear takes the book when windowing position 51, can be through rubberizing mechanism 7 with the interlude adhesion in the outside that corresponds the gauze mask in ear area, make the ear area fix and roll over, like this when 6 entering slitting mechanisms 8 through the compress cylinder, slitting mechanisms 8 can directly cut the gauze mask, need not to avoid flagging ear area, more be favorable to shortening the segmentation flow, and the later stage ejection of compact and material returned are more convenient.

Gluing mechanism 7 can adopt the glue gun to spout gluey, spouts the glue gun through the organic silica gel or the automatic hot melt adhesive machine that jet easily tears the type, bonds the ear area middle section in the gauze mask outside, like this after the gauze mask ejection of compact, can directly pack. When in use, the middle section of the ear belt is pulled out for use. Of course, the gluing mechanism 7 can also adopt the easily torn gummed paper with the base glue and the back glue, the cut easily torn gummed paper segment can be prepared in advance, the gluing mechanism 7 can be an air cylinder, the easily torn gummed paper segment is conveyed to the end part of the air cylinder through a conveyor of the gummed paper segment, the air cylinder directly presses the easily torn gummed paper on the middle section of the ear band, the easily torn gummed paper segment is attached to the outer side of the mask, the ear band can be folded upwards and fixed, and the follow-up process is facilitated. In summary, the gluing mechanism is just a mechanism capable of performing gluing, and many gluing mechanisms in the prior art are applied, and many embodiments are not presented herein, and the gluing device should fall within the scope of the present invention.

It is to be understood that the technical scope of the present invention is not limited to the contents of the specification, and that modifications or changes may be made by those skilled in the art based on the above description, and all such modifications and changes are intended to fall within the scope of the appended claims.
