A combed cotton web shearing device

Abstract

A combed cotton net shearing device comprises a base which is provided with an objective table; the lower end of the objective table is provided with a lead screw; one end of the lead screw is fixedly connected with a driving handle; the lead screw is provided with a mobile table; the lead screw is connected with the mobile table through a lead screw nut pair; a blade control frame is fixedly arranged on the mobile table; a blade is fixedly arranged on the blade control frame; the objective table is provided with a scale. According to the combed cotton net shearing device, the driving handle rotates, the lead screw rotates along with the rotation of the driving handle, and the lead screw rotates a circle to enable the mobile table to move 1mm; the length of a cotton net can be measured and the head end of the cotton net can be effectively positioned to enable the every time of cutting length to be accurate due to the scale; the cutting length adjustment method is simple in operation and the cutting length of the cotton net can be effectively and accurately set; the 2mm segmental cutting can be accurately and effectively performed on the cotton net, the shearing efficiency is high, the use and the operation are convenient, the minimum shearing length is 1mm, and the cutting requirements of various fiber nets can be met.

Description

technical field [0001] The invention relates to the technical field of textile experiment detection, in particular to a combed cotton web shearing device. Background technique [0002] The combed cotton web is formed by superimposing and lapping the individual separated bundles output by the separating rollers of the combing machine. Its quality is an important indicator for evaluating the performance of the combing machine. In order to obtain accurate weight distribution curves of single separated plexus and cotton web weight distribution curve, predict and evaluate the quality of combing, it is necessary to cut and weigh a single separated plexus with a length of 2 mm or less. At present, when fibers are cut, two methods of manual cutting or mechanical cutting are usually used. Manual cutting has high labor intensity and low work efficiency. During the cutting process, there is a phenomenon of fiber slippage, and the cutting accuracy is poor. Disadvantages of the mechani...

Problems solved by technology

Manual cutting has high labor intensity and low work efficiency. During the cutting process, there is a phenomenon of fiber slippage, and the cutting accuracy is poor.

Disadvantages of the mechanical cutting method: first, the shortest cutting length is 5mm, which is greater than the 2mm cutting requirement of the combed cotton web; second, the existing fiber cutting technology is mainly used for cutting fiber bundles or monofilaments, not for cotton webs cut
