Fiber combustion sample preparation machine

Abstract

The invention is a fiber burning sample preparation machine, which includes synchronous sample clamps and twisting sample clamps located on the left and right sides respectively, and a wire roll support for installing a wire roll; and also includes left and right guide rods, wire rods A rod and a mobile bench connected with the lead screw and slidable along the guide rod; the inner end of the mobile bench is respectively connected with a sample bracket and a damper support ring, and the sample bracket is provided with a bracket thread hole; It includes a damper with a large port and a small port at both ends. The small port of the damper is used to constrain the fiber sliver but allow the fiber sliver to slide along the hole wall of the small port; the damper is provided with a damper threading hole ; A locking mechanism is arranged between the damper and the damper support ring. In the present invention, the motor drives the sliver to rotate and twist and wrap and fix the metal wire, so that each sample is prepared under the same operating conditions, and the consistency of the finished product is guaranteed.

Description

technical field [0001] The present invention relates to a machine for preparing fiber burning samples. Background technique [0002] Fire endangers people's life and property, destroys economic construction, seriously affects people's normal work and life, and causes huge economic losses and personal casualties. There are many reasons for fires. In order to reduce the fire caused by textiles and provide the basis for protective materials, research on textile flame retardant technology, development and use of flame retardant textiles, and flame retardant performance testing are the topics faced by the industry. Fire prevention must be at the source, and fire protection measures also need to test the combustion performance of related fibers. The combustion performance of fibers is related to the basic indicators of the flame retardant performance of finished products such as yarns, woven fabrics, and clothing. [0003] The fibers are made into strips and fixed with metal wire...

Problems solved by technology

[0004] At present, when preparing samples for this project, it is generally completed by manual operation. The main defects are: low efficiency, and the manual operation is not standardized enough, and the samples processed by different operators or even the same operator are quite different. These differences mainly reflect In terms of twisting strength, twisting uniformity, sample density, sample density uniformity, and the number and shape of sample surface hairiness (referring to the fiber ends that are not attached to the sample body), these factors will affect combustion. performance test results
