Detailed Description

Referring to fig. 1, an annular spinneret concentricity adjustment tool, adjustment rod 1100 and microscope 1200 are provided above annular groove 23 of annular spinneret holder 20.

As shown in fig. 2 and 3, the adjusting rod 1100 includes two rod bodies 1110, an adjusting member 1120 for driving the two rod bodies 1110 to move away from or close to each other, and two fixing sleeves 1130.

The two rods 1110 have opposite screw threads at the head ends thereof, and the two rods 1110 have the same screw threads at the tail ends thereof.

The adjusting member 1120 is provided with two connecting holes 1121 with overlapped central lines, one connecting hole 1121 is connected with the head end of one rod body 1110 through a positive thread, the other connecting hole 1121 is connected with the head end of the other rod body 1110 through a negative thread, and the two rod bodies 1110 can be simultaneously far away from or close to each other by rotating the adjusting member 1120.

The two connecting holes 1121 are respectively provided with a first screw 1122 for radially locking the two rods 1110.

The two fixing sleeves 1130 are symmetrically fixed on the inner ring 21 of the annular spinneret plate clamp 20, and each fixing sleeve 1130 includes a sleeve body 1131, a thread inner sleeve 1132 arranged in the sleeve body 1131, and a second screw 1133 used for radially locking the thread inner sleeve 1132, and the thread inner sleeve 1132 is connected with the tail end of the rod body 1110 through threads.

When the spinning device is used, the two fixing sleeves 1130 are symmetrically fixed on the inner ring 21 along the diameter of the inner ring 21, the first screw 1122 and the second screw 1133 are loosened, the adjusting member 1120 is rotated up and down to simultaneously separate the two rods 1110 until the tail ends of the two rods 1110 contact the annular spinneret plate 30, at this time, the first screw 1122 and the second screw 1133 are locked, after the first screw 1122 is locked, the two rods 1110 and the adjusting member 1120 form a whole, any one of the three can be rotated up and down simultaneously, and the two rods 1110 and the adjusting member 1120 can be simultaneously moved radially and simultaneously due to the fact that the second screw 1133 locks the thread inner sleeve 1132, so that the position of the annular spinneret plate 30 in the annular groove 23 is finely adjusted, meanwhile, the microscope 1200 is matched to observe a positioning mark preset on the annular spinneret plate 30, and when the positioning mark is observed, the annular spinneret plate 30 and the annular spinneret plate clamp 20 are in a concentric state, the operation is simple, the efficiency is high, and the position of the punching equipment does not need to be adjusted in the subsequent punching.

For example, the lens of the microscope 1200 may be disposed above a half of the radial width of the annular groove 23 of the annular spinneret holder 20, and accordingly, the positioning mark may be disposed at a half of the radial width of the annular surface 31 of the annular spinneret 30.

As shown in fig. 3, in this embodiment, the fixing sleeve 1130 further includes a third screw 1134 for axially limiting the tail end of the shaft 1110, and the fixing sleeve 1130 on the retracted side of the shaft 1110 is limited by the third screw 1134 to stabilize the concentric state.

As shown in fig. 2-4, in this embodiment, the underside of sleeve body 1131 forms a mounting seat 1131a for mounting with mounting hole 21a on annular spinneret holder inner ring 21.

Specifically, the fixing seat 1131a is in a column shape.

In the present embodiment, the two adjusting rods 1100 are arranged in a cross shape, and the adjusting tube 1120 of one adjusting rod 1100 is U-shaped, see fig. 1.

The two adjusting rods 1100 are arranged in a cross shape, wherein the adjusting part 1120 of one adjusting rod 1100 is tubular, two connecting holes 1121 are formed at two ends of the adjusting part, and the adjusting part of the other adjusting rod 1100 is a U-shaped block body, two connecting holes 1121 are formed at two ends of the adjusting part, so that the two adjusting rods 1100 can be prevented from interfering, as shown in fig. 1.

However, those skilled in the art should realize that the above embodiments are only used for illustrating the present invention and not used as a limitation of the present invention, and that the changes and modifications to the above embodiments are within the scope of the appended claims as long as they are within the true spirit of the present invention.
