Description

Technical Field

[0001] The invention relates to a shock-absorbing sealing device and a shock-absorbing sealing method, and in particular to a shock-absorbing sealing device and a shock-absorbing sealing method for a carbon fiber spinneret. Background Art

[0002] At present, the spinnerets on the market use rigid contact seals or detachable sealing rings, and the spinnerets do not take overpressure and overload protection into consideration. When the working pressure of the spinnerets exceeds the standard, it is easy to cause the spinnerets to deform.

[0003] Ordinary spinnerets have the following defects when performing spinning: 1. Sealing problem: The spinneret flange has high flatness requirements, and most of them use rigid plane seals or sealing rings.

[0004] 2. Transient pressure overload protection problem: Ordinary spinneret assemblies do not have a structure that can achieve pressure overload protection. When the working pressure exceeds the yield strength of the material, the spinneret will deform.

[0005] 3. Shock absorption problem: Ordinary spinnerets generally do not consider the shock absorption problem.

[0006] Through domestic search, it was found that the following patents have similarities with the present invention: The utility model with application number 201920278592.1 and name "A stainless steel spinneret for carbon fiber spinning processing" discloses a stainless steel spinneret for carbon fiber spinning processing, including an anti-stripping threaded connecting column and a fixed ring, wherein a spinning plate is sleeved at the middle outer wall position of the anti-stripping threaded connecting column. Because an internal threaded trapezoidal fixing ring and an anti-stripping threaded connecting column are installed, the staff first rotates and fixes an internal threaded trapezoidal fixing ring with an external threaded body through an internal thread body, and then aligns the anti-stripping threaded connecting column with one side of the internal threaded trapezoidal fixing ring with the external fixing column, and sleeves it on the outer wall of the external fixing column, and then sleeves the connecting hole in the spinning plate on the outer wall of the fixed connecting column, and then rotates and connects it to the anti-stripping threaded connecting column through another internal threaded trapezoidal fixing ring, and also makes the spinning plate move and fixedly connected in the anti-stripping coating, thereby avoiding damage to the spinning plate, which not only improves the installation efficiency, but also reduces the damage rate of the equipment.

[0007] The utility model with application number 202220340137.1 and name "A multi-channel spinneret" provides a multi-channel spinneret, which relates to the technical field of spinnerets, solves the problems of installation and fixation of spinnerets, and flexible switching of spinnerets, and includes a spray pipe; a connecting flange is provided above the spray pipe; the support assembly is locked at the bottom of the spray pipe by bolts, and the support assembly is composed of a positioning ring, a connecting rod and a mounting ring, and the mounting ring has a threaded connection sleeve, and a locking bolt is installed in the threaded connection sleeve. The spinneret is driven to rotate by the rotating support assembly, and the spinneret is set to three. The flexible switching of the spinneret is completed by the rotation of the support assembly, thereby improving the replacement efficiency of the spinneret and solving the problem of troublesome replacement of the spinneret. The spinneret is set to be clamped, so as to facilitate the installation and disassembly of the spinneret. The support assembly and the spinneret cooperate to make the installation structure of the spinneret simple and convenient for the operation of the spinneret.

[0008] The utility model with application number 202223396477.5 and name "A new type of carbon fiber spinneret" relates to the technical field of spinnerets, specifically a new type of carbon fiber spinneret, side panels are provided on both sides of the baffle, the side panels are located above the side blocks, and the lower ends of the side panels are provided with positioning blocks inserted into the positioning grooves, and the lower ends of the baffles are provided with baffles. Through the mutual cooperation between the positioning blocks and the positioning grooves, a positioning effect can be provided between the side panels and the side blocks, so that the baffles can be easily installed on the fixed seat, and the sealing of the empty grooves can be improved by the baffles and baffles, so that the bolts can be protected. When the carbon fiber spinneret body is used for a long time, the bolts will not be affected by the air humidity and rust, so that the bolts can be easily loosened, so that the carbon fiber spinneret body can be easily disassembled temporarily.

[0009] Although the above patents all involve spinnerets, especially the utility model with application number 202223396477.5 and titled "A New Type of Carbon Fiber Spinneret" also involves the sealing performance of the spinneret. However, the structure of the spinneret in the above patents is different from that in the present invention application, especially the spinneret in the above patents is not provided with an annular shock-absorbing sealing ring, and its shock-absorbing and sealing effects are difficult to improve, and it is also difficult to protect the spinneret from transient pressure overload. Summary of the invention

Figure 1 ; Figure 3 The overall structure of the first embodiment is shown in FIG. Figure 2 ; In the figure: base 11, upper annular groove 12, flange edge 21, shock-absorbing sealing ring 22, plate wall 23, bottom plate 24, end cover 31, lower annular groove 32, bolt 33. DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with embodiments and drawings: Embodiment 1

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the shock-absorbing sealing device includes a base 11, a carbon fiber spinneret and an end cover 31. The base 11 is arranged above the carbon fiber spinneret, and the end cover 31 is arranged below the carbon fiber spinneret. The base 11 and the end cover 31 are both in the shape of a circular tube. The carbon fiber spinneret includes a flange 21, a plate wall 23 and a bottom panel 24. The flange 21, the plate wall 23 and the bottom panel 24 are all rotating bodies, and the flange 21, the plate wall 23 and the bottom panel 24 are integrally formed into a whole. The upper end of the plate wall 23 is seamlessly connected to the inner side of the flange 21, and the lower end of the plate wall 23 is seamlessly connected to the bottom panel 24.

[0025] The upper and lower surfaces of the flange 21 are both vulcanized with a shock-absorbing sealing ring 22, which is annular. The shock-absorbing sealing ring 22 is set to be annular, so that when the carbon fiber spinneret is subjected to external force, the shock-absorbing effect of the carbon fiber spinneret in all directions is uniform. The flange 21 is also annular, and the bottom panel 24 is a circular plate that is concave downward. The width of the annular shock-absorbing sealing ring 22 is smaller than the width of the annular flange 21.

[0026] A through mounting hole is opened in the circumferential direction of the end cover 31, and a threaded mounting hole corresponding to the mounting hole on the end cover 31 is opened at the bottom of the base 11. The bolt 33 passes through the mounting hole on the end cover 31 and is tightened in the threaded mounting hole of the base 11 to press the vulcanized shock-absorbing sealing ring 22 on the flange edge 21. The end cover 31 and the base 11 together seal the circumferential direction of the carbon fiber spinneret and damp the fiber spinneret in the vertical and horizontal directions.

[0027] An upper annular groove 12 matching the shape, size and position of the shock-absorbing sealing ring 22 on the upper surface of the flange 21 is provided at the bottom of the inner side of the base 11, and a lower annular groove 32 matching the shape, size and position of the shock-absorbing sealing ring 22 on the lower surface of the flange 21 is provided at the top of the inner side of the end cover 31. The degree of compression of the shock-absorbing sealing ring 22 by the base 11 and the end cover 31 is adjusted by changing the width and depth of the upper annular groove 12 and the lower annular groove 32, thereby adjusting the shock absorption and pressure overload protection effect of the fiber spinneret.

[0028] The width and depth of the upper annular groove 12 and the lower annular groove 32 can be optimized according to the specific working conditions of the fiber spinneret, so that the shock-absorbing sealing ring 22 can better buffer the pressure and prevent the spinneret from plastic deformation, thereby improving the shock-absorbing effect and pressure overload protection effect of the fiber spinneret.

[0029] The shock-absorbing sealing device of this embodiment has a simple structure, which enables the spinneret to have shock-absorbing performance and impact resistance in all directions, while solving the problem of transient pressure overload protection. The flange edge 21 is vulcanized with high-temperature resistant elastic rubber to solve the sealing problem of the spinneret.

[0030] Obviously, without departing from the principles of the present invention, several improvements or modifications made should be considered as within the protection scope of the present invention.
