Description

Technical Field

[0001] The utility model relates to the technical field of filter discs, in particular to a recyclable filter disc for a spinneret. Background Art

[0002] The spinneret, also known as the spinning cap, is a commonly used product in the textile and chemical fiber industry. The function of the spinneret is to transform the viscous polymer melt or solution into a thin flow with a specific cross-section through micropores, and solidify it through a coagulation medium such as air or a coagulation bath to form a filament, that is, it enters from the feed hole and exits from the discharge hole through the spinneret channel. The meltblown fabric spinneret is an important component in the production device of meltblown fabric for masks. There are spinneret holes on the spinneret, and a filter is often installed on the injection port of the meltblown fabric spinneret;

[0003] It is found during the use of the existing spinneret filter that the filter needs to be cleaned every period of time to prevent impurities in the raw material solution from clogging the filter. However, the injection port is often directly connected to the feed pipe, which makes it difficult to remove the filter for cleaning. Disassembly is troublesome and time-consuming, which reduces work efficiency and leads to poor practicality. Utility Model Content

[0008] By adopting the above technical solution, the conveying pipe is connected to the first feeding pipe. The connection can be made using locking parts such as clamps, and the present application does not impose specific restrictions, so that the raw material solution can pass through the first feeding pipe and the filter screen in turn, and after being filtered by the filter screen, it enters the spinneret body through the second feeding pipe. When the filter screen needs to be cleaned, first release the limit of the slide plate by the limiting mechanism, and then rotate the screw rod, and the movable plate screwed with the screw rod moves to the left, driving the slide plate to move to the left. After the slide plate is disengaged from the first through hole, the slide plate is pulled out of the groove for cleaning. This process realizes an easy disassembly process, improves work efficiency, and thus enhances practicality.
