Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

An assembling device of a mask filter cloth, comprising: a workbench 104, an assembling device 02 and a mask cloth superposing device 07;

the assembling device 02 and the mask cloth superposing device 07 are sequentially arranged on the workbench 104; the mask cloth superposing device 07 is used for conveying the mask cloth 05 and/or the nose bridge strip 06 to the assembling device 02;

assemble device 02 for assemble multilayer gauze mask 05 and nose bridge piece 06, include: the device comprises a division plate 2, a nose bridge strip assembling component 1 and an edge sealing device 3;

subassembly 1 is assembled to nose bridge strip includes: the nose bridge cutting device comprises a cutting table 15, a nose bridge strip conveying assembly 11, a nose bridge strip cutting wheel 12 and a nose bridge strip cutter 13;

the cutting table 15 is mounted to the panel 2; the nose bridge strip conveying assembly 11 and the nose bridge strip cutting wheel 12 are sequentially arranged and are positioned above the cutting table 15; the nose bridge strip transmission assembly 11 is used for transmitting the nose bridge strip 06 to the nose bridge strip cutting wheel 12; the nose bridge strip cutter 13 is mounted on the nose bridge strip cutting wheel 12, one end of the nose bridge strip cutter 13 extends out of the outer side of the nose bridge strip cutting wheel 12, and the nose bridge strip cutter cuts the nose bridge strip at a cutting table 15 when rotating synchronously with the nose bridge strip cutting wheel 12;

the plurality of layers of the mask cloth 05 passes below the cellular board 2 and receives the cut nose bridge strips at the position extending out of the cutting table 15; the edge sealing device 3 is used for jointing the plurality of layers of the mouth covering cloth and/or jointing the nose bridge strip to the mouth covering cloth.

This assembly device can pass through bridge of the nose strip conveying assembly 11, bridge of the nose strip cutting wheel 12, bridge of the nose strip cutter 13 and between the cooperation, has realized the effect of multilayer gauze mask cloth 05 coincide in the gauze mask processing to set up bridge of the nose strip 06 in following multilayer gauze mask cloth 05, make gauze mask processing lines can reach full automated processing's effect.

The mask cloth 05 is a material with filtering effect for forming a known mask, such as non-woven fabric and/or melt-blown non-woven fabric, and is output to the assembling device 02 by a mask cloth laminating device 07 with rolling and unreeling functions in the front end respectively; the nose bridge strip 06 is a strip in the mask for fixing the mask cloth to the nose bridge of the user, and may be plastic or metal, and is output to the assembling device 02 by the mask cloth folding device 07 with the rolling and unwinding functions in the front end.

Specifically, the nose bridge strip conveying assembly 11 conveys a whole unwound nose bridge strip to the nose bridge strip cutting wheel 12, and as the nose bridge strip cutting knife 13 is synchronously and rotatably mounted on the nose bridge strip cutting wheel 12, the nose bridge strip cutting knife 13 presses the nose bridge strip to the cutting table 15 after rotating, so that the nose bridge strip can be cut off; as shown in fig. 2, a gap is formed between the lower part of the division plate 2 and the horizontal supporting plate of the processing base 01, the multi-layer mask cloth passes through the gap in sequence, and the arrow direction is the moving direction of the mask cloth; because the division plate 2 has a limited height effect on the mask cloth, the mask cloth is pressed when passing below the division plate 2, so that the multiple layers of mask cloth are more tightly jointed; when the mask cloth is input from the right side of the division plate 2 and output from the left side of the division plate 2, the surface of the mask cloth passes through the cutting table 15 and receives the nose bridge strips, so that the positioning and fitting effects of a plurality of layers of mask cloth and the nose bridge strips in the mask are realized; after the multilayer mask cloth receives the nose bridge strip, the nose bridge strip can be conveyed to the edge sealing device 3, and the step that the nose bridge strip is fixed on the mask cloth and the step that the mask cloth is sealed are completed.

Here, the step of transferring the nose bridge strip to the face of the mask cloth may be replaced by a known component or principle; for example, the nose bridge strip is driven to move to the surface of the mask through a common horizontal driver (such as a known driver such as an air cylinder); or the cut nose bridge strip falls to the surface of the mask cloth under the action of gravity, and the like.
