Problems solved by technology

At present, most of the dry-process fiber fabric forming equipment adopts rotary screen forming. In this method, a breaking roller is generally installed in a screen drum, and the fiber clusters are broken up by a high-speed rotating screen drum or a breaking roller, and the dispersed fibers are screened out by centrifugal force. In this method, because the fibers move in different directions when they are scattered, the static electricity generated by mutual friction is relatively large. During the laying process, the fibers are easy to stick again, and the direction of the fibers is different. The sedimentation process is also disturbed by the airflow of the rotating parts. Fiber distribution uniformity and web laying uniformity

Abstract

The invention discloses novel dry-process fiber fabric forming equipment belonging to the field of dry-process fiber fabric equipment. According to the equipment, air is used as a carrier for dispersing and transporting fibers, raw fiber agglomerates are scattered by using a scattering fan, and the dispersed fibers fall off after being sieved by using a vibrating screen and are uniformly spread on a forming net under the guide of a negative-pressure draught fan to form a fabric. the fiber agglomerates and the dispersed fibers move towards the same direction in the fiber scattering process, so that static electricity is not easily generated, and the fibers are uniformly dispersed; no air flow disturbance of the blades of the scattering fan is generated when the net is spread, so that the net spreading quality is high; and the unutilized fiber agglomerates are circularly operated, so that the utilization ratio of raw materials is high.

Description

technical field [0001] The invention belongs to the technical field of dry-laid fiber fabric equipment, and in particular relates to a novel dry-laid fiber fabric forming equipment. Background technique [0002] The dry-laid fiber fabric forming equipment is the key equipment in the production of dry-laid paper, dry-laid special fabrics, and dry-laid reconstituted tobacco leaves. It is different from the fiber fabric forming equipment under the traditional process. Air is used instead of water as the carrier for dispersing and transporting fibers during web laying operations, and the fibers are initially formed into fabrics on the forming net by suction of air. The forming quality directly limits and affects the grade specifications and physical properties of the finished fabric. For dry-laid fiber fabric forming equipment, it is mainly measured from three aspects: the dispersion of fiber clusters, the uniformity of fiber distribution and the uniformity of laying. At presen...
