Description

Technical Field

[0001] The utility model relates to the technical field of spinnerets, in particular to an annular spinneret. Background Art

[0002] The spinneret is also called the spinning cap. The function of the spinneret is to transform the viscous polymer melt or solution into a thin stream with a specific cross-section through the micropores, and solidify it through a coagulation medium such as air or a coagulation bath to form a filament. Its shape can be round, rectangular, fan-shaped, etc.

[0003] When using existing spinnerets, sometimes multiple spinnerets need to be spliced ​​together for use, and most of them are fixed by bolts. After long-term use, the sealing rings between the spinnerets are easily damaged. When disassembling, supporting tools are required for disassembly and maintenance, which is very troublesome. For this reason, we propose an annular spinneret. Utility Model Content

Under the action of external force, the sliding rope 9 can slide in the inner wall of the fixed rod 4, so that the sliding rope 9 drives the block 5 to move out of the inside of the slot and retract into the inside of the fixed rod 4.

[0028] In another embodiment, if Figure 2 , Figure 6 , Figure 7 As shown, one end of the block 5 passes through the outer wall of the fixed rod 4 and extends to the outside of the fixed rod 4, one end of the sliding rope 9 passes through the inner wall of the fixed rod 4 and extends to the outside of the fixed rod 4, and one end of the limiting rod 6 passes through the inner wall of the fixed rod 4 and extends to the inside of the fixed rod 4.

[0029] The clamping block 5 , the limiting rod 6 , and the sliding rope 9 can all slide inside the fixing rod 4 under the action of external force.

[0030] In another embodiment, if Figure 2 As shown, one end of the sliding rope 9 is fixedly mounted on the outer wall of one side of the handle 10, and the outer wall of the handle 10 is slidably mounted on the inner wall of the spinneret 1, and a placement groove adapted to the handle 10 is provided on the outer wall of the spinneret 1.
