Non-woven fabric edge cutting mechanism for mask machine

Abstract

The invention discloses a non-woven fabric edge cutting mechanism for a mask machine. The edge cutting mechanism comprises a box body, a base plate and a cross beam; the box body is fixedly connected to the base plate; the cross beam is fixedly arranged on the two opposite inner side walls of the box body; a set of electric push rods are fixedly connected to the lower surface of the cross beam; pressing plates are fixedly connected to the lower ends of the electric push rods; the edge cutting mechanism further comprises cutting mechanisms and auxiliary pressing mechanisms; the auxiliary pressing mechanisms are arranged on the two inner side walls of the box body; and the cutting mechanisms are used for cutting the edge of a non-woven fabric. When a photoelectric sensor in the box body detects that the length of the non-woven fabric reaches a set value, the electric push rods can push the pressing plates fixedly connected below to move downwards and press the non-woven fabric, then the cutting mechanisms arranged on the two sides of the box body can move downwards, and the auxiliary pressing mechanisms can be pushed to work in the downward moving process of the cutting mechanisms, so that the cutting mechanisms can perform rapid cutting subsequently, and the loss of cutters can also be reduced.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric trimming equipment, in particular to a non-woven fabric trimming mechanism for a mask machine. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Non-woven fabric has no warp and weft, it is very convenient to cut and sew, and it is light and easy to shape. It is very popular among handicraft lovers because it is a kind of fabric that does not need spinning and weaving. The filaments are oriented or randomly arranged to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. It is not interwoven and knit...

Problems solved by technology

[0003] Because it is not made by weaving method, there is no warp and latitude in the non-woven fabric, so the edge of the non-woven fabric is less smooth than the edge of the woven fabric. Before the non-woven fabric is made into a roll, the uneven edge needs to be cut off. Most of the existing edge trimming equipment is mechanical knife cutting, so it is necessary to set the knife groove to facilitate cutting. If the knife groove is too large, it will easily cause the non-woven fabric to be embedded in the knife groove during cutting and cause cloth damage. If the knife groove is too small easy to damage the blade
