Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: the feed rollers are mostly made of metal, but metals are conductive materials. It will lead away part of the static electricity on the melt-blown cloth, which will reduce the adsorption and filtration effect of the melt-blown cloth on bacteria and dust, thereby reducing the overall filtering effect of the mask

Embodiment 1

[0048] The invention discloses a production line for masks with high static electricity, such as figure 1 and figure 2 As shown, it mainly includes a frame 1 and a feeding device 2 arranged on the frame 1. The frame 1 is located behind the feeding device 2 and is also equipped with a folding device, a tendon feeding device, a welding wheel, a slicing device, and an ear strap. Welding device, earband hemming device, hemming cutting device and finished product feeding rack (not shown in the figure). The feeding device 2 includes a feeding roller 22 and a stacking roller 21 that are rotatably arranged on the frame 1. In this embodiment, the feeding roller 22 includes a raw material roller 221 and a guide roller 222, and the raw material roller 221 is rotatably arranged on the frame. 1 is used to place the raw material rolls of the outer layer cloth, the inner layer cloth and the melt blown cloth. In this embodiment, the outer layer cloth, the inner layer cloth and the melt blow...

Embodiment 1

[0051] For the first embodiment, the present invention also provides a method for producing a mask with high static electricity, including the steps of feeding, folding, feeding ribs, welding, slicing, earband welding, earband wrapping, and wrapping cutting;

[0052] Wherein, the feeding step comprises the following steps:

[0053] Unwinding: the melt-blown cloth roll, the inner layer cloth roll and the outer layer cloth roll are hung on the raw material roller 221 in advance, and under the traction of the traction device (not shown in the figure), the melt-blown cloth, the inner layer cloth and the outer layer The cloth is released from the melt-blown cloth roll, the inner layer cloth roll and the outer layer cloth roll respectively, and then the melt-blown cloth, the inner layer cloth and the outer layer cloth are conveyed towards the laminating roller 21 through the guide roller 222 .

[0054] Lamination: When the meltblown cloth, inner layer cloth and outer layer cloth are...

Embodiment 3

[0059] A production line of masks with high electrostatic capacity, such as image 3 As shown, the difference between the second embodiment and the first embodiment is that in this embodiment, the outer peripheral wall of the feed roller 22 will be coated with an insulating coating 5, and the insulator layer can be coated by Teflon paint. As a result, the insulating coating 5 can reduce the electrostatic conduction of the melt-blown cloth by the conveying roller 22 during the conveying process of the melt-blown cloth.

Abstract

The invention relates to a production method and a production line of a high-static mask, which relates to the field of mask production and aims to solve the problem that the electrostatic loss on the melt-blown cloth reduces the filtering effect of the mask during the production process of the existing mask. The production method of the invention comprises the following steps: feeding; stacking: the melt blown cloth, the inner layer cloth and the outer layer cloth are laminated into a mask cloth, and the melt blown cloth is located between the inner layer cloth and the outer layer cloth; after the melt blown cloth is discharged 1. Before being laminated to the middle of the inner cloth and the outer cloth, static electricity is added to the melt-blown cloth, and the melt-blown cloth after the addition of static electricity is laminated between the inner cloth and the outer cloth to form a mask cloth. According to the present invention, before the melt-blown cloth is laminated with the rest of the cloth layers, electrostatic supplementation is carried out on the melt-blown cloth, which can well improve the electrostatic content of the melt-blown cloth in the finished mask, thereby greatly improving the filtering effect of the mask, and not only making the mask The quality is excellent, and the production cost of the mask is saved.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a production method and production line of masks with high electrostatic capacity. Background technique [0002] Mask is a kind of sanitary product, which generally refers to an appliance worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose; existing masks can be divided into ordinary Disposable masks and medical disposable masks, etc. [0003] Among them, medical disposable masks mainly include a hygroscopic layer (inner layer), a filter layer and a water blocking layer (outer layer). The moisture-absorbing layer is attached to the face; the water-blocking layer is located on the outside of the mask and contacts the outside air; the filter layer is the core layer, which is used to filter bacteria and dust in the gap; the existing filter layer is mostly melt...
