Description

Gauze mask folder

Technical Field

The utility model relates to a corollary equipment in the gauze mask production especially relates to a gauze mask folder.

Background

The mask is a medical protective article for isolating dust, bacteria, viruses and the like, is divided into a disposable medical surgical mask, a reusable N95 mask and the like according to the protection grade, and is basically formed by heat sealing of a plurality of filter layers no matter what mask is used.

For an N95 mask, an existing N95 mask is shown in fig. 1, and fig. 1 shows an N95 mask 1 in a folded state, which has more filter layers, is harder, and has a larger volume than a common disposable medical external mask, and in order to facilitate transportation and sale of the N95 mask, the N95 mask needs to be folded by a mask folding machine before being shipped from a factory and then packaged. Item 2 in the figure represents an elastic band.

Current gauze mask folder includes a backup pad, is fixed with vertical layout's cylinder in the backup pad, is fixed with the folded sheet on the piston rod of cylinder, is provided with the folding seam that a length extends along the fore-and-aft direction and correspond the setting with the folded sheet in the backup pad, and the downside of folded sheet is provided with a pair of folding roller that can rotate relatively by motor drive. During the use, operating personnel lays N95 gauze mask in the backup pad upside, and the folding seam is aimed at to the intermediate position of N95 gauze mask, and the piston rod of cylinder is down, and the folded sheet is preliminary folding with the N95 gauze mask, and the folded sheet sends the N95 gauze mask to between two folding rollers simultaneously, and the relative rotation of two folding rollers rolls the N95 gauze mask foldingly to accomplish final folding.

The existing mask folding machine has the problems that: the interval between two folding rollers is fixed, just in time matches the thickness of two-layer N95 gauze mask, and this will lead to, and highly required very strict down to the folded sheet, and the descending distance of folded sheet is too big, and the folded sheet will block between two folding rollers, and the descending height of folded sheet is not enough, just can't send N95 gauze mask to between two folding rollers smoothly, because the problem of the descending height of folded sheet, often can lead to the production to suspend, seriously influences production efficiency.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a mask folder to solve among the prior art folding plate down highly low easy jamming between two folding rollers technical problem.

In order to solve the technical problem, the utility model discloses in a technical scheme of gauze mask folder as follows:

the utility model provides a gauze mask folder, which comprises a supporting plate, be fixed with vertical arrangement's cylinder in the backup pad, be fixed with the folded sheet on the piston rod of cylinder, be provided with length in the backup pad along the extending folding seam that corresponds the setting with the folded sheet of fore-and-aft direction, the downside of folded sheet is provided with a pair of folding roller that can rotate relatively by motor drive, one of them folding roller of definition is the folding roller in left side, another one folding roller is the folding roller in right side, the folding roller in left side and/or the folding roller in right side are installed on relocation mechanism, relocation mechanism includes the mechanism seat and supplies to correspond the folding roller support that the folding roller rotated the installation, folding roller support include with the mechanism seat direction removes complex guide bar in the left and right directions, the guide bar upper shield is connected with floating spring.

Furthermore, the left folding roller and the right folding roller are both installed on the corresponding floating mechanism, and the left folding roller and the right folding roller are symmetrically arranged by taking the central line in the width direction of the folding seam as the central line.

Further, the width of the folding seam gradually narrows from top to bottom.

Further, the maximum downward moving position of the folding plate is arranged between the left folding roller and the right folding roller.

Furthermore, a left side positioning plate and a right side positioning plate which are respectively used for being in contact positioning fit with the left side edge and the right side edge of the N95 mask are fixed on the left side and the right side of the folding seam on the supporting plate, and a left front side positioning plate and a right front side positioning plate which are respectively used for being in contact positioning fit with the left front side edge and the right front side edge of the N95 mask are fixed on the front sides of the left side positioning plate and the right side positioning plate on the supporting plate.

Further, the piston rod lower extreme of cylinder sets up the mounting groove that extends along upper and lower direction, and on the lower extreme of mounting groove extended to the lower terminal surface of piston rod, the upper end of folded sheet was located the mounting groove, and threaded connection has on the cell wall of mounting groove and is used for the top tightly the top screw of folded sheet.

Furthermore, the lower end face of the folding plate is of an arc-shaped structure, and the axis of the arc-shaped structure is in contact fit with the N95 mask and extends in the front-back direction.

The beneficial effects of the utility model are that: the utility model discloses in, the folding roller in left side and/or the folding roller in right side are installed on relocation mechanism, consequently, the folding roller in left side, interval between the folding roller in right side can float and change, during the use, the folded sheet is down, with folding seam cooperation, send into between the folding roller in left side and the folding roller in right side after tentatively folding N95, because the folding roller in left side, interval between the folding roller in right side is variable, consequently, the folded sheet can not the jamming at the folding roller in left side, between the folding roller in right side, the folded sheet goes upward afterwards, the folding roller in left side, the folding roller in right side is drawn close each other again and is accomplished the final folding to the N95 gauze mask.
