Description

A store up silk mechanism for wet spinning produces line

Technical Field

The invention relates to the technical field of chemical fiber wet spinning mechanical equipment, in particular to a filament storage mechanism for a wet spinning production line.

Background

The wet spinning production line is equipment for producing fiber membranes, such as Chinese patent with publication number of CN107913603A, with patent name of 'braided tube reinforced hollow fiber membrane and preparation device and production process thereof', the device recorded by the method comprises a wire supply mechanism, a pre-coating machine head, a coagulating tank, a rinsing tank, a wire take-up mechanism and a wire winding wheel, in the spinning process, after the braided tube is sequentially pre-coated and coated with the high-molecular polyester stock solution by the pre-coating machine head and the pre-coating machine head, the hollow fiber membrane enters a coagulating bath tank to react with a formula liquid in the coagulating bath tank, so that a high-molecular polyester raw material is coagulated to form a hollow fiber membrane taking a braided tube as an inner support, the formed hollow fiber membrane is pressed into a rinsing tank (namely a cleaning tank) to be cleaned, and finally the hollow fiber membrane is collected through a wire winding wheel, and in the collecting process, a wire collecting mechanism ensures that the fiber membrane is wound by the wire winding wheel at constant tension.

The length of the formed fiber membrane is equal to that of the braided tube used as the lining, so the fiber membrane cannot be directly and effectively utilized, the fiber membrane is cut into small sections which can be utilized after being collected, but the conventional wet spinning production line of the patent does not have the cutting function, so the collected fiber membrane needs to be taken down from the filament winding wheel for cutting, before the fiber membrane is cut, the fiber membrane is continuously conveyed outwards from the cleaning tank and pulled to the cutting tool, so the cutting tool can cut the fiber membrane, and the filament collecting mechanism cannot continuously ensure that the braided tube can be subjected to constant tension because the fiber membrane is separated from the filament winding wheel, so when the tension applied to the fiber membrane is small, the fiber membrane is easily accumulated between the cleaning tank and the filament cutting mechanism, and winding and stacking are easy to occur when a large number of fiber membranes are processed, and the quality of subsequent finished products is influenced, therefore, the current common method is to increase the distance between the cleaning tank and the silk cutting mechanism and further increase the length of the fiber membrane between the cleaning tank and the silk cutting mechanism, but the method undoubtedly increases the occupied area of the whole wet spinning production line, which not only causes shortage of land space, but also limits the operation activities of operators, and when the pulling force pulling the fiber membrane outwards is large, namely the tensile force applied to the fiber membrane is large, the fiber membrane is easy to break due to the large tensile force applied to the fiber membrane.
