Problems solved by technology
[0003] The existing cutting tool for medical non-woven masks has a simple structure and lacks a pressing device. During the cutting process, the cloth is prone to offset, especially when cutting in batches, the thickness of the non-woven fabric is relatively large, which affects the quality of the mask. Production accuracy, in addition, the cutters for cutting non-woven masks in batches are relatively large, and the long-term friction and high temperature of the cutters will heat the cutting edges, causing the edges of the non-woven fabrics to shrink and affect the quality of the masks

Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0031] see Figure 1-3 , a batch cutting tool for medical non-woven masks, including a tool body 1, a groove 11 is opened inside the upper end of the tool body 1, and a notch 111 is opened on one side of the upper end of the notch 11, and the notch 111 is used for ventilation, cold air Enter the groove 11 through the gap 111 to cool down the tool body 1. The installation frame 2 is fixedly connected to the inside of the groove 11. The two side wa...

The invention discloses a cutter and a method for batch cutting of a medical non-woven mask. The cutter comprises a cutter body, wherein a groove is arranged in the upper end of the cutter body; a mounting frame is fixedly connected to the interior of the groove; a first ventilation hole and a second ventilation hole are arranged in the two side walls of the cutter body respectively; a lug is connected to one side, close to the first ventilation hole, of the cutter body; the lug is connected to a limiting frame through a bolt; and the upper end of the mounting frame penetrates through the groove and is connected to a mounting clamping groove. According to the cutter and the method for batch cutting of the medical non-woven mask, the groove is arranged in the cutter body, the mounting frameis connected to the interior of the groove, the weight of the cutter body is reduced through the groove, meanwhile, cold air can enter the cutter body through a third ventilation hole and the secondventilation hole, the cutter body is cooled, the crimp of the non-woven fabric on the cut edge is prevented, and the non-woven fabric is compressed before and after the cutting operation of the cutterbody, so that the position offset of the non-woven fabric is avoided; and the cutter is simple in structure and easy to control.
Description
technical field [0001] The invention relates to the technical field of mask cutting tools, in particular to a batch cutting tool and method for medical non-woven masks. Background technique [0002] There are two kinds of non-woven masks, one is made of pure cotton absorbent gauze or knitted fabric on the surface, and various non-woven fabrics are sandwiched in the middle; the other is directly sewn from non-woven fabrics. Its filtering effect is good, but the air permeability is slightly poor. The latest variety is made of non-woven fabric materials on the surface and back, and filter paper in the middle, so that the filtering effect of non-woven masks can be improved to a higher level. The dust suppression efficiency of non-woven masks is based on its blocking efficiency for fine dust, especially for respirable dust below 5 microns. Because dust of this particle size can directly enter the alveoli, it has the greatest impact on human health. The general gauze mask, its d...
