Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spinneret processing, in particular to a spinneret processing equipment. BACKGROUND

[0002] The function of the spinneret is to convert the high polymer melt or solution in the sticky flow state into a fine stream with a specific cross section through the micro-holes. During the processing of the spinneret, the surface of the spinneret needs to be polished. Because the surface of the spinneret is very large, the cutter can only polish the local position of the surface of the spinneret at the same time point when the cutter contacts the surface of the spinneret. During the polishing process of the cutter on the spinneret, the surface of the spinneret slides due to the transverse action of the cutter, and the transverse position of the spinneret deviates. In the subsequent processing of the spinneret by the cutter, the processing quality of the surface of the spinneret is affected due to the movement of the transverse position of the spinneret.

[0037] The function of the spinneret is to convert the high polymer melt or solution in viscous flow state into a stream with a specific cross section through the micro-holes. In the process of processing the spinneret, the surface of the spinneret needs to be polished. Because the surface of the spinneret is very large, the cutter can only polish the local position of the surface of the spinneret at the same time point when the cutter is in contact with the surface of the spinneret. In the process of polishing the spinneret by the cutter, the surface of the spinneret slides due to the transverse action of the cutter, the horizontal position of the spinneret deviates, and in the subsequent processing of the spinneret by the cutter, the quality of the processing of the surface of the spinneret is affected due to the movement of the horizontal position of the spinneret.

[0038] In view of the above technical problems, the embodiment provides a spinneret processing equipment, referring to Figure 1 and Figure 2 , the spinneret processing equipment includes an inverted L-shaped machine frame 5, a rectangular cutter holder 2 is fixed on the upper part of the machine frame 5 along the transverse direction by bolts, and a polishing cutter 3 is rotatably installed on the cutter holder 2 along the longitudinal direction downward. A motor 1 is vertically fixed on the cutter holder 2 by bolts, the lower end of the output shaft of the motor 1 is fixed on the upper end of the polishing cutter 3 by bolts, and the motor 1 drives the polishing cutter 3 to rotate in the process of rotation. The polishing cutter 3 includes a circular cutter, and a cutter rod is vertically fixed on the cutter by bolts.

[0039] The processing table 4 is located at the lower part of the machine frame 5, and is positioned longitudinally directly below the grinding tool 3. The spinneret to be processed is fixed inside the processing table 4. The shank of the grinding tool 3 can extend and retract axially, and the grinding tool 3 can be raised and lowered longitudinally to adjust it to a position in contact with the spinneret. The motor 1 rotates to drive the grinding tool 3 to rotate, and the grinding tool 3 grinds the upper surface of the spinneret to achieve the processing of the spinneret.

[0040] Reference Figure 3 The processing table 4 includes an operating frame 42, a radial locking member 43, and an axial locking member 41. The operating frame 42 includes a circular retaining ring 421, and a semi-circular top plate 423 is bolted to the top of the retaining ring 421 in a direction perpendicular to the axial direction of the retaining ring 421. The top plate 423 covers half of the top port of the retaining ring 421.

[0041] A support plate 425 is placed in the lower part of the inner cavity of the retaining ring 421. The peripheral side of the support plate 425 is attached to the inner side wall of the retaining ring 421. The retaining ring 421, the support plate 425, and the top plate 423 form an operating cavity 422. After the spinneret to be processed is placed in the operating cavity 422, the spinneret is on the support plate 425. The retaining ring 421 limits the spinneret from the periphery, and the top plate 423 limits the position of the spinneret from above.

[0042] Multiple radial locking members 43 are radially installed within the side wall of the operating frame 42 at multiple positions along the circumference of the operating frame 42. One end of each radial locking member 43 extending into the operating frame 42 abuts against the peripheral side of the spinneret along the radial direction. Each radial locking member 43 abuts against the outer peripheral wall of the spinneret at different positions along the radial direction of the operating frame 42. Under the radial pressure of the multiple radial locking members 43, the spinneret is clamped and fixed, thus firmly securing it at the center of the multiple radial locking members 43. This achieves a firm radial fixation of the spinneret, improving its lateral stability during processing. This ensures the spinneret remains in a stable lateral position during processing, facilitating accurate alignment of the grinding tool 3 with the spinneret and ensuring the processing quality of the spinneret.

[0043] Axial locking member 41 is disposed on top plate 423 in a direction perpendicular to top plate 423. The lower end of axial locking member 41 passes downward through top plate 423 and is pressed against the top surface of spinneret. The position of the lower end of axial locking member 41 is adjusted according to the thickness of spinneret to be processed, so that axial locking member 41 can firmly press spinneret in the longitudinal direction, thereby improving the stability of spinneret during processing, facilitating accurate alignment of grinding tool 3 with spinneret, and ensuring the processing quality of spinneret. The longitudinal fixation of spinneret by axial locking member 41 will be described in detail later.

[0044] That is, after the spinneret is placed into the operating cavity 422 formed by the retaining ring 421, the bearing plate 425, and the top plate 423, multiple radial locking members 43 clamp and fix the spinneret laterally from different positions along the radial direction to achieve radial fixation of the spinneret. The axial locking member 41 fixes the spinneret longitudinally from top to bottom to achieve longitudinal fixation of the spinneret. The radial and lateral fixation of the spinneret is achieved through the radial locking members 43 and the axial locking members 41, improving the stability of the spinneret during processing.

[0045] Reference Figure 4 The operating frame 42 includes a base 426. The bottom of the base 426 is disc-shaped, and the upper part of the central part of the base 426 is cylindrical. The disc part at the bottom of the base 426 is fixed to the lower part of the machine frame 5 with bolts. In the longitudinal direction, the base 426 is coaxially arranged at the bottom of the inner cavity of the retaining ring 421.

[0046] The support plate 425 is coaxially and rotatably fitted onto the top of the base 426. A circular rotating groove is formed at the center of the lower part of the support plate 425. The upper cylindrical part of the central part of the base 426 is supported in the rotating groove. The support plate 425 is rotatably mounted on the top of the base 426. The positioning bolt 427 is installed radially inside the side wall of the retaining ring 421. One end of the positioning bolt 427 extending into the interior of the retaining ring 421 is threaded radially to the edge of the support plate 425.

[0047] The top plate 423 is semi-circular, and it partially obscures the spinneret. (See reference...) Figure 4When viewed from above, only a portion of the spinneret is visible, and the grinding tool 3 grinds only this exposed portion. After the exposed portion of the spinneret is ground, the positioning bolt 427 is rotated to loosen the support plate 425. The support plate 425 is then rotated, causing the spray plate placed above it to rotate. The processed portion of the spinneret is rotated to below the top plate 423, while the unprocessed portion of the spinneret is rotated out and exposed below the grinding tool 3. The grinding tool 3 then continues to grind the unprocessed portion of the spinneret to achieve comprehensive grinding of the spinneret surface.

[0048] Reference Figure 4 Multiple discharge grooves 424 are formed along the circumference of the retaining ring 421 at its upper edge. Each discharge groove 424 is a wedge-shaped groove, and the longitudinal position of the port extending to the inner wall of the retaining ring 421 is higher than the longitudinal position of the port extending to the outer wall of the retaining ring 421. Metal waste generated during the polishing process of the spinneret slides along the discharge grooves 424 to the outside of the retaining ring 421. Timely discharge of processing waste facilitates smooth processing.

[0049] Reference Figure 5 The axial locking member 41 includes a rectangular locking cover 412, which extends horizontally on the top surface of the top plate 423 and is fixed to the top surface of the top plate 423 with bolts. A cylindrical pressing rod 411 slides within the locking cover 412 in a direction perpendicular to the locking cover 412. When the pressing rod 411 moves longitudinally, it drives the first pressing plate 414 and the second pressing plate 417 to move to the target position. Then, the pressing rod 411 is locked to the locking cover 412 with bolts.

[0050] A first pressing plate 414 and a second pressing plate 417 are vertically bolted to the lower ends of two adjacent pressing rods 411. The first pressing plate 414 and the second pressing plate 417 are thin plates. The opposite ends of the first pressing plate 414 and the second pressing plate 417 have triangular concave and convex surfaces. The opposite ends of the second pressing plate 417 and the first pressing plate 414 have triangular concave and convex surfaces. The concave and convex surfaces at the end of the second pressing plate 417 and the concave and convex surfaces at the end of the first pressing plate 414 are staggered in the longitudinal direction. The triangular convex surface at the end of the first pressing plate 414 abuts against the triangular concave surface at the end of the second pressing plate 417. The opposite ends of the first pressing plate 414 and the second pressing plate 417 in the transverse direction are engaged by the triangular concave and convex surfaces.

[0051] The first pressing plate 414 and the second pressing plate 417 both press against the upper surface of the spray plate to be processed, providing lateral friction to the upper surface of the spray plate they are in contact with, thereby achieving lateral fixation of the spray plate. Even if the spray plate is subjected to lateral force from the grinding tool 3 during processing, it can still maintain lateral stability under the action of the lateral friction of the first pressing plate 414 and the second pressing plate 417.

[0052] The first pressing plate 414 and the second pressing plate 417 are subjected to opposing forces while simultaneously fixing the spray plate laterally. In this embodiment, the first pressing plate 414 and the second pressing plate 417 are engaged by the concave and convex surfaces of opposite triangles in the lateral direction to achieve a stable lateral engagement, thereby improving the stability of the contact between the first pressing plate 414 and the second pressing plate 417.

[0053] During the processing, the first pressing plate 414 and the second pressing plate 417 can achieve mutual support in the lateral direction by the cooperation of the concave and convex surfaces of the triangles at their ends, thereby improving the positional stability of the first pressing plate 414 and the second pressing plate 417 and achieving stable fixation of the spray plate in the lateral direction.

[0054] A triangular, convex-concave buffer strip 416 made of rubber is pressed laterally between a first pressing plate 414 and a second pressing plate 417.

[0055] During the grinding process of the spinneret, the first pressing plate 414 and the second pressing plate 417 press against the upper surface of the spinneret to fix its position.

[0056] The second pressing plates 417 achieve lateral support through the interlocking of the concave and convex surfaces of their triangular ends, thereby enhancing the lateral support capacity of the first pressing plate 414 and the second pressing plate 417. A rubber buffer strip 416 is pressed laterally between the first pressing plate 414 and the second pressing plate 417, absorbing compressive force and providing cushioning, further improving the lateral support capacity of the first pressing plate 414 and the second pressing plate 417.

[0057] Reference Figure 5 A rectangular friction plate 415 is bolted to the bottom surface of the first pressing plate 414 and the second pressing plate 417 respectively. The friction plate 415 is made of rubber material and is attached to the upper surface of the spinneret. A rectangular groove is provided on the lower surface of the friction plate 415 for contact with the spinneret to further increase the friction between the friction plate 415 and the spinneret. As the lateral friction between the friction plate 415 and the spinneret increases, the stability of the first pressing plate 414 and the second pressing plate 417 in fixing the spinneret is improved.

[0058] Reference Figure 6 The elastic seat 413 is disposed on the side wall of the pressing rod 411. The elastic seat 413 presses downward against the top surface of the first pressing plate 414 to press the first pressing plate 414 downward onto the spinneret. Under the longitudinal pressing force of the elastic seat 413, the stability of the first pressing plate 414 pressing the spinneret longitudinally is improved.

[0059] Reference Figure 6 The elastic seat 413 includes a first pressing seat 4131, which is rectangular and bolted to the side wall of the pressing rod 411. A second pressing seat 4136, also rectangular, is pivotally connected to the side wall of the pressing rod 411. The second pressing seat 4136 is longitudinally positioned below and aligned with the first pressing seat 4131. A cylindrical steering column 4135 is rotatably connected to the pressing rod 411. A rectangular partition 4134 is bolted to the steering column 4135 along its radial direction. A clamping block 4133 is bolted to the partition 4134 in a direction perpendicular to the partition 4134. The lower part of the clamping block 4133 is rectangular, and the top part is T-shaped. A rectangular support groove is provided at the lower part of the first pressing seat 4131, and the upper end of the pressing block 4133 slides in the support groove. The lower end of the pressing block 4133 presses against the top surface of the second pressing seat 4136.

[0060] The spring clip 4132 is formed by bending spring steel. The spring clip 4132 slides in the support groove. The upper end of the pressing block 4133 extends into the support groove from bottom to top and presses the spring clip 4132 against the first pressing seat 4131.

[0061] During the grinding process of the spinneret, the first pressing seat 4131 pushes the clamping block 4133 downward through the spring clip 4132. The lower end of the clamping block 4133 presses down onto the second pressing seat 4136. Under the push of the clamping block 4133, the second pressing seat 4136 presses the first pressing plate 414 downward onto the spinneret to help improve the firmness of the longitudinal compression of the spinneret.

[0062] Reference Figure 7 The radial locking member 43 includes a locking frame 435 and a positioning rod 436. The middle part of the locking frame 435 is rectangular, and the two ends of the locking frame 435 are cylindrical. The circular positioning rod 436 connects the locking frame 435 to the side wall of the retaining ring 421 by threads, and the locking frame 435 extends along the height direction of the retaining ring 421.

[0063] A circular clamping rod 432 is slidably inserted into the locking frame 435. A radial friction plate 431 is bolted to one end of the clamping rod 432 that extends into the retaining ring 421. A squeezing groove is provided on the side of the radial friction plate 431 opposite to the clamping rod 432. The squeezing groove is arc-shaped and contacts the outer circumferential wall of the spinneret to achieve circumferential clamping and fixation of the spinneret.

[0064] Multiple radial friction plates 431 are pressed radially onto the outer wall of the spinneret from multiple positions to achieve clamping and fixing of the spinneret from multiple positions around the periphery, thereby improving the stability of the spinneret fixing.

[0065] The sealing cap 438 is threaded to the outer wall of the retaining ring 421 along the radial direction of the retaining ring 421, and the other end of the clamping rod 432 is threaded to the sealing cap 438. The spring 437 is sleeved on the outside of the clamping rod 432. The sealing cap 438 is a circular cap with a pressing groove on one side. The spring 437 slides in the pressing groove, and the sealing cap 438 presses the spring 437 against the side wall of the locking frame 435.

[0066] Multiple trapezoidal second elastic teeth 434 are bolted circumferentially to the inner wall of the locking frame 435, extending radially along the inner cavity of the locking frame 435. A toothed groove is pre-formed between adjacent second elastic teeth 434 along the axial direction of the inner cavity of the locking frame 435. A first elastic tooth 433 is bolted to the outer wall of the tightening rod 432, extending radially along the tightening rod 432. The first elastic tooth 433 is located within the toothed groove between adjacent second elastic teeth 434 and is clamped and fixed by the second elastic teeth 434 on both sides.

[0067] The tensioning rod 432 and the locking frame 435 are linked by the engagement of the first elastic tooth 433 and the second elastic tooth 434. The sealing cover 438 is fixed on the retaining ring 421 and pushes the tensioning rod 432 radially, which presses the radial friction plate 431 against the periphery of the spinneret.

[0068] The edge of the sealing cap 438 abuts radially against the side wall of the locking frame 435, pressing the locking frame 435 toward the center of the retaining ring 421. The locking frame 435, through the first elastic tooth 433 and the second elastic tooth 434, drives the top clamping rod 432 to press against the friction plate 431 toward the center of the retaining ring 421. Furthermore, the sealing cap 438 presses the spring 437 against the side of the locking frame 435. Under the pushing action of the spring 437, the locking frame 435 drives the top clamping rod 432 to press the friction plate 431 against the periphery of the spinneret.

[0069] The sealing cap 438 applies radial pressure to the edge portion of the locking frame 435, the spring 437 applies radial pressure to the edge portion of the locking frame 435, and the locking frame 435 drives the top rod 432 radially through the first elastic tooth 433 and the second elastic tooth 434, so that the top rod 432 stably presses the friction plate 431 to the periphery of the spinneret, thereby improving the stability of clamping the spinneret on the outer periphery.

[0070] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
