Description

TECHNICAL FIELD

[0001] The utility model relates to fine denier filament production technical field especially relates to a fine denier filament winding monitoring device. BACKGROUND

[0002] The spinning production process usually includes dry chip - melt extrusion - pre - filtration - mixing - metering - filtration - spinning - cooling - oiling - winding.

[0003] The spinning process is to spray the molten polymer through the spinneret and cool to form a bundle 20. After the bundle 20 comes out of the port, it passes through several guide rollers 30, and then passes through the monitoring device 40 to monitor the state of the bundle. Then, the bundle passes through the guide porcelain piece 50 and finally enters the winding machine 60 for winding. The monitoring device is used to monitor whether the bundle is broken. After the monitoring device judges that one or more bundles are broken, it feeds back to the control system, and the control system controls the cutter arranged at the port to cut off all the bundles to prevent the bundle from winding the equipment.

[0004] In the prior art, the monitoring device is integrated, and the adjacent detection ends in the monitoring device are arranged closely. When the bundle passes through the monitoring device, the relative position relationship between the bundle and the detection end is as shown in Figure 1 Since the multiple detection ends are arranged closely and the several bundles enter the winding machine for winding in an eight-shaped manner, the angle deviation between the bundle and the detection end is large, and the position of the bundle and the detection end 41 is not correct. When producing a product with a large fiber diameter, since the fiber diameter is large, even if the position of the bundle and the detection end is not correct, the detection end of the monitoring device can still normally monitor whether the bundle is broken and will not misjudge. However, when producing fine denier filament products, since the fine denier filament has a small diameter, the position of the bundle and the detection end of the monitoring device is not correct, which is easy to cause misjudgment, so that the cutter cuts off all the yarns, affecting the AA rate (full winding rate) of the winding machine.
