Fiber Cutter

Abstract

The invention discloses a fiber cutting machine, which comprises a wire wheel mechanism, a cutting mechanism and a tensioning mechanism located between the wire wheel mechanism and the cutting mechanism. The wire wheel mechanism includes a wire wheel fixing frame and at least one wire fixed on the wire wheel fixing frame. The wheel part, the wire wheel part includes a wire wheel, and the outer side of the wire wheel is covered with a tow sleeve composed of long filament bundles to be cut. The cutting mechanism includes a frame, a cutter head, a first power device for driving the cutter head to rotate, The pressure wheel that can press the filament bundle on the cutter head and the tension adjustment device for adjusting the tension of the filament bundle. The power unit, the pressure roller and the tension adjustment device are all fixed on the frame. The force adjustment device is located on the side of the cutter head close to the wire wheel mechanism, the pressure wheel is located on the side of the cutter head away from the wire wheel mechanism, and the output shaft of the power device is connected to the cutter head; the tensioning mechanism includes a tensioning wheel fixing frame, a tensioning wheel The fixed frame is provided with at least one tensioning wheel for tensioning the filament bundle. The invention can make the tension force of cutterhead cutting when the filament bundle is produced.

Description

technical field [0001] The invention relates to the field of short fiber production, in particular to a fiber cutting machine for cutting long filament bundles into short fibers. Background technique [0002] Short fiber, also known as cut fiber, the cutting process is the last process in the production process of short fiber. It is the short fiber cut into the long fiber bundle by the cutting machine. However, the existing cutting machine is cutting the long fiber bundle Sometimes, the filament bundle between the wire wheel and the cutter head may loosen, which will cause the cutter head on the cutting machine to fail to cut the filament bundle into short fibers well. If the cutter head on the cutting machine is to be smooth To cut filament bundles, it is necessary to turn off the starting power of the cutting machine first, and then manually tighten the filament bundles between the wire wheel and the cutter head, so that the filament bundles can be suitable for the cutter ...

[0002] Short fiber, also known as cut fiber, the cutting process is the last process in the short fiber production process. It is the short fiber cut into the long filament bundle by a cutting machine. However, the existing cutting machine is cutting the long filament bundle Sometimes, the filament bundle between the wire wheel and the cutter head will loosen, which will cause the cutter head on the cutting machine to fail to cut the filament bundle into short fibers well. If the cutter head on the cutting machine is to be smooth To cut filament bundles, it is necessary to turn off the starting power of the cutting machine first, and then manually tighten the filament bundles between the wire wheel and the cutter head, so that the filament bundles can be suitable for cutting filament bundles by the cutter head. tension, which is not only very time-consuming and labor-intensive, but also greatly reduces the production efficiency of short fibers
