An important link in the existing mask production process is roll forming, a knurling roller is used, the knurling roller is used for rolling and ultrasonically welding multiple layers of mask materials together, the knurling roller is an extremely important consumable in the roll forming link, the production and manufacturing period of the knurling roller is extremely long, the manufacturing process is complex, and the longest consumed construction period is that patterns are carved out on a cylindrical shaft by using a 4-shaft machining center in machining. The knurling roller of the mask of the N95 type is the most difficult to process in the 4-axis engraving process, and the engraving time of only 4 axes is as long as more than 24 hours.
Therefore, when the masks need to be produced in large quantities in an emergency under the condition of emergent infectious diseases, the knurling roller becomes an obstacle to continuous mass production of the masks, and the phenomenon that the knurling roller is short in supply and short in demand is formed.
Through research and analysis, the situation that the supply of the mask machine knurling roller is not in short time is caused, and besides the increase of mask machine equipment, the mask machine knurling roller has the following reasons: 1. for example, as the chinese patent No. CN205601155U, the teeth on the knurling roll are straight teeth (as shown in fig. 6), so that the tooth top and tooth root have the same width, and the tooth root with vertical sharp corner is prone to crack during heat treatment, so that the tooth root is stressed, fatigued and broken during rolling, and the whole knurling roll must be scrapped as long as one tooth is broken. This is a main reason why the lifetime of the knurling roller is not long. 2. The four-axis engraving time is long, the knurling roller is wound on a cylinder by a plurality of teeth, ribs and the like, the knurling roller is complex and difficult to machine, in addition, the width and the distance of the convex teeth are usually below 2mm, the tooth height is usually 1.5-2.5 times of the tooth distance, thus a cutter with the diameter smaller than 2mm and the length larger than 2.5 times of the diameter is needed to machine, the small cutter is slender and can only cut into a small depth and feed a little for engraving and milling, and the cutter can be broken at a higher speed.
In conclusion, the short service life and the long production period lead to the shortage of the knurl roller.
