Intelligent mask machine and its die-cutting mechanism manufacturing method

- Jun 12, 2020-

Background technique:


The current mask production process generally includes processes such as wrinkling, hemming, welding forming, die cutting, welding ear straps, etc. The die cutting process refers to cutting the strip of mask material into mask pieces that meet the specifications, while welding the ears The strapping process is to weld the ear straps on the mask pieces that meet the specifications to achieve the wearing function. Obviously, the above-mentioned production process has many procedures, takes a long time, and has a low production capacity. It is unable to cope with the huge demand for masks in emergency situations, such as when there is a sudden outbreak of an infectious disease.


Technical realization elements:


The purpose of the utility model is to provide a die-cutting mechanism capable of reducing the production process of a mask and an intelligent mask machine including the same.


In order to achieve the above object, the present invention provides a die-cutting mechanism, which includes: a frame; a bottom roller, which is arranged on the frame; a cutting roller, which is arranged on the frame and is arranged side by side with the bottom roller ; Drive assembly, set on the frame, used to drive the bottom roller and the cutting roller to rotate towards each other; wherein, the cutting roller is provided with a number of cutting blades arranged along its circumference, each Each of the cutting blade groups includes at least one cutting blade and at least two cutting blades, the cutting blade and the cutting blade both extend along the axial direction of the cutting roller, and the cutting blade The cutting rollers are circumferentially arranged and symmetrically distributed on both sides of the slitting knife, and each of the hole-cutting knives has at least two perforating edges.


Another object of the present invention is to provide an intelligent mask machine including the above-mentioned die cutting mechanism.

The utility model provides a die-cutting mechanism. Compared with the prior art, the beneficial effects are as follows:


The die-cutting mechanism provided by the utility model includes a frame and a bottom roller, a cutting roller and a driving assembly arranged on the frame. The bottom roller and the cutting roller are arranged side by side. The driving component is used to drive the bottom roller and the cutting roller to rotate towards each other; The cutting roller is provided with a number of cutting blade groups arranged along its circumferential direction. Each cutting blade group includes at least one dividing knife and at least two cutting blades. The cutting blade and the cutting blade are along the cutting roller. Extending in the axial direction, the hole-cutting knives are arranged along the circumferential direction of the cutting roller and symmetrically distributed on both sides of the slitting knife, and each hole-cutting knife has at least two perforating edges. Based on the above structure, the bottom roller is equivalent to a chopping board, and the continuous mask material passes through between the cutting roller and the bottom roller and is cut by the slitting knife of the cutting knife group into a number of mask pieces that meet the specifications. The two sides of the boundary between two adjacent mask pieces are cut by the cutting knife of the cutting knife group to cut out the through hole for the ear band to pass through. Therefore, the mask piece obtained by the die cutting mechanism only needs to be matched with a separate Ear straps can be put on the market without welding ear straps. Based on this, the die-cutting mechanism provided by the present invention can reduce the production process of the mask, shorten the production cycle of the mask, and greatly increase the production capacity of the mask, thus being able to cope with the huge demand for masks in emergency situations.


In addition, the utility model also provides an intelligent mask machine. Because it adopts the above-mentioned die cutting mechanism, it has the advantages of high production efficiency and large production capacity.
