Description

Technical Field

[0001] This utility model belongs to the field of nonwoven equipment technology, specifically relating to a cutting mechanism for a slant mesh forming machine suitable for biodegradable and washable wet-process wood pulp nonwoven fabric. Background Technology

[0002] The inclined wire forming machine is one of the more commonly used nonwoven equipment. The paddle box spreads wood pulp evenly on the wire mesh to form fibers. After forming, edge trimming is usually required to maintain the smoothness of the edges. With increasing environmental awareness, environmentally friendly nonwoven fabrics have received widespread attention. Among them, biodegradable and washable nonwoven fabrics are currently among the most popular. These environmentally friendly nonwoven fabrics typically incorporate chopped fibers such as Tencel and viscose, which increases both cost and the toughness of the formed fiber web. However, conventional edge trimming devices are no longer sufficient to handle the cutting of these fibers. Furthermore, existing edge trimming devices, due to their lower precision, are prone to uneven cutting, high paper waste, and even incomplete cutting, seriously affecting the quality of the formed fiber web. High paper waste also means more wasted wood pulp, which increases the manufacturing cost of the finished product.

[0003] In view of the above, it is necessary to design a cutting mechanism for a slanted wire forming machine that is simple in structure, low in cost, has high processing accuracy and low paper loss rate, and can effectively cut washable wet-laid wood pulp nonwoven fabric. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this background. Utility Model Content

[0009] In another specific embodiment of this utility model, the trimming frame is fixed to the corresponding slider by screws. A trimming frame connecting shaft is welded to the trimming frame. One end of the first clamp is wrapped around one end of the trimming frame connecting shaft. The first clamp can rotate and adjust around the trimming frame connecting shaft, and the angle is locked by screws. The other end of the first clamp is wrapped around a separating cutting nozzle connecting shaft. The separating cutting nozzle connecting shaft can rotate and adjust, and the angle is locked by screws. The separating cutting nozzle is fixed to a fourth clamp.
