Description

Technical Field

[0001] The utility model relates to the technical field of spinneret equipment, in particular to a multifunctional polyester fiber spinneret. Background Art

[0002] In the production process of polyester fiber, the molten polymer needs to be sent to the spinning machine, spun out by the spinneret, and then cooled by air and wound into the yarn drum to obtain the raw yarn. 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.

[0003] For example, the invention patent with authorization announcement number CN115341287B discloses a multifunctional chemical fiber spinneret. The device controls the spinneret to move upward, thereby causing the support plate, the clamping block and the clamping spring to move upward. The clamping block moves upward and contacts with the spinneret device body, so that the spinneret device body will squeeze the clamping block, and then under the action of the clamping spring, the clamping block is clamped into the clamping groove of the spinneret device body, thereby enabling the spinneret to be quickly fixed on the spinneret device body.

[0004] However, when the device is used, since the aperture of the spinneret is fixed, when products of different thicknesses need to be processed, the spinneret needs to be replaced with a suitable spinneret for processing, which reduces the processing efficiency and cannot meet the use requirements well.

[0027] The working principle of the utility model is as follows: during processing, firstly, a suitable spinneret with a spinneret hole of suitable aperture is selected. When the spinneret 3 is selected for processing, the spinneret fixing seat 35 is rotated to drive the spinneret 3 to rotate, so that the spinneret cavity 31 is moved to the top of the spinneret orifice 11. At the same time, the spinneret fixing seat 45 is rotated to drive the spinneret 4 to rotate through the spinneret fixing seat 45, so that the material guide cavity 43 is moved to the top of the spinneret orifice 11.

[0028] When the spinneret 24 is selected for processing, the spinneret 24 is driven to rotate by rotating the spinneret fixing seat 245, so that the spinneret cavity 241 is moved to be directly above the spinneret orifice 11. At the same time, the spinneret fixing seat 135 is rotated to drive the spinneret 13 to rotate through the spinneret fixing seat 135, so that the material guide cavity 133 is moved to be directly above the spinneret orifice 11. At this time, the viscous fluid polymer sprayed from the spinneret device body 13 is extruded from the spinneret holes on the spinneret 24 to complete the processing. It is convenient to select a suitable spinneret for processing according to actual needs, and there is no need to frequently disassemble and replace the spinneret, which can better meet the use requirements.

[0032] When it is necessary to move the spinneret positioning seat 1 35 (or spinneret positioning seat 2 45), first install the fixed stopper 52 that fits therewith and retract it into the fixed seat 51. At this time, the fixed spring 53 is compressed. Then the spinneret positioning seat 1 35 (or spinneret positioning seat 2 45) can be rotated. Then, the fixed stopper 52 is released and the fixed stopper 52 on one side is pressed to retract it into the fixed seat 51. The spinneret positioning seat 1 35 (or spinneret positioning seat 2 45) can drive the spinneret plate 1 3 (or spinneret plate 2 4) to rotate 90°.
