Description

Technical Field

[0001] This application relates to the field of winding equipment, and in particular to an anti-eccentric winding device. Background Technology

[0002] Graphite spiral wound gaskets are sealing elements made of a composite of metal strips and flexible graphite material, manufactured using an alternating spiral winding process. The core components of a graphite spiral wound gasket include metal strips and flexible graphite strips, which are spirally wound to form a multi-layered composite structure.

[0003] When the aforementioned metal strip and flexible graphite strip are mechanically wound through the equipment, it is necessary to ensure that the position of the output end of the metal strip corresponds to that of the flexible graphite strip. Due to the characteristics of the flexible graphite strip, its position will not change much during winding. The main requirement is to restrict the position of the metal strip. The existing method of restriction is to cut grooves on the rotating shaft for forming the graphite winding pad to provide certain restrictions for the metal strip and the flexible graphite strip.

[0004] In the actual production process described above, when the metal strip winds through the groove on the shaft to the second half, it still exhibits a certain degree of eccentricity. Utility Model Content

[0005] To better prevent the metal strip from eccentrically winding, this application provides an anti-eccentric winding device.

[0006] The anti-eccentric winding device provided in this application adopts the following technical solution:

[0007] An anti-eccentric winding device includes a mounting rod and a through block. One end of the mounting rod has an external thread, and the other end of the mounting rod extends through the through block. The through block has a limiting hole for a metal strip to pass through. The limiting hole passes straight through the through block, and the orientation of the limiting hole relative to the mounting rod is fixed during use.

[0008] By adopting the above technical solution, the mounting rod can be fixed to the winding equipment at one end via external threads, thereby stabilizing the entire anti-eccentricity device on the winding equipment. As an auxiliary component, the anti-eccentricity device can be adjusted in position and is also easy to remove for maintenance. In operation conditions where the anti-eccentricity device is not required, the entire anti-eccentricity device can be removed without affecting the operation of the equipment. The metal strip passes through the mandrel block at the other end of the mounting rod. The limiting hole on the mandrel block restricts the position of the metal strip, so that the end of the metal strip near the winding position is located in the designated position. The mandrel block restricts the part of the metal strip from the output point to the winding point, thereby limiting the eccentricity of the metal strip and playing an anti-eccentricity role.

[0009] Optionally, the through block is provided with a supporting suspension block, the suspension block extending in the same direction as the opening direction of the limiting hole, and the supporting suspension block is located below the opening of the limiting hole at one end through which the metal strip passes and supports the metal strip.

[0010] By adopting the above technical solution, the metal strip is further guided to output and wind in the corresponding direction by the support suspension block. The support suspension block occupies less space and is less prone to interference.

[0011] Optionally, the support block has a limiting groove for the metal strip to pass through, and the bottom of the limiting groove is on the same plane as one of the walls of the limiting hole.

[0012] By adopting the above technical solution, the limiting groove opened on the support block can further limit the eccentric movement of the metal strip.

[0013] Optionally, it also includes clamping plates and a main mounting nut. There are two clamping plates, and the through block is clamped and fixed between the two clamping plates. A limiting screw head is provided at one end of the mounting rod, and the main mounting nut is threaded onto the mounting rod. The two clamping plates are clamped and fixed between the limiting screw head and the main mounting nut.

[0014] By adopting the above technical solution, the clamping plate is securely fixed to the mounting rod by the main mounting nut. By loosening the main mounting nut, the clamping plate can be rotated relative to the mounting rod, thereby adjusting the position of the through block on the clamping plate to better adapt to the running trajectory of the metal strip. As a result, when the mounting rod is installed on the equipment, it is not affected by the position of the through block, which facilitates the installation of the mounting rod. After the installation of the mounting rod is completed, the position of the through block can be adjusted.

[0015] Optionally, a first bolt assembly is installed between the two clamping plates. The first bolt assembly includes a first screw and a first nut. The first screw passes through the through block, and the through block is provided with a limiting structure that restricts the rotation of the through block relative to the first screw.

[0016] By adopting the above technical solution, the through block is installed more stably between the clamps through the first bolt assembly, making it less likely to fall off on its own. The limiting structure keeps the position of the through block relative to the clamps stable, ensuring that the through block remains stationary when the metal strip passes by.

[0017] Optionally, the through-hole block is threadedly engaged with the first screw to form the limiting structure.

[0018] By adopting the above technical solution, the through block is threadedly engaged with the first screw, while the clamping plate prevents the axial movement of the through block relative to the first screw, ultimately preventing the through block from rotating relative to the first screw and achieving a stationary state of the through block relative to the clamping plate. It utilizes the first screw without any additional structure, making it simple and effective.

[0019] Optionally, a second bolt assembly is installed between the two clamping plates, the mounting rod mates with the middle of the clamping plate, and the through block and the second bolt assembly are respectively installed on the portions of the clamping plate located on both sides of the mounting rod. The second bolt assembly includes a mating block clamped between the two clamping plates.

[0020] By adopting the above technical solution, the mating block of the second bolt assembly restricts the two clamping plates from getting close to each other. With the cooperation of the through block, both ends of the two clamping plates are restricted from getting close to each other, so that the two clamping plates can be stably clamped and fixed on the mounting rod. Compared with the case where only one end of the clamping plate is restricted by the through block, the possibility of clamping plate deformation is reduced, the gravity distribution of the clamping plate relative to the mounting rod is balanced, and the position of the through block can be adjusted by adjusting the position of the clamping plate.

[0021] Optionally, the clamping plate on one side of the mounting rod has a first mounting position for installing the through block. There are multiple first mounting positions, which are evenly and equidistantly arranged. The clamping plate on the other side of the mounting rod has a second mounting position for installing the second bolt assembly. There are multiple second mounting positions, which are evenly and equidistantly arranged. The distances of the multiple first mounting positions and the multiple second mounting positions relative to the mounting rod correspond one-to-one.

[0022] By adopting the above technical solution, the position of the through block can be adjusted by changing its first mounting position, and the second mounting position of the second bolt assembly can be adjusted accordingly to maintain the balance of gravity distribution, which is always conducive to adjusting the rotational displacement of the clamping plate relative to the mounting rod.

[0023] In summary, the mounting rod can be fixed to the winding equipment at one end via external threads, thus securing the entire anti-eccentricity device to the winding equipment. As an auxiliary component, the anti-eccentricity device can be adjusted in position and is easy to remove for maintenance. In operating conditions where the anti-eccentricity device is not needed, the entire device can be removed without affecting equipment operation. The metal strip passes through the mandrel at the other end of the mounting rod, and the limiting hole on the mandrel restricts the position of the metal strip, ensuring that the end of the metal strip near the winding position is in a designated position. The mandrel restricts the portion of the metal strip between the output point and the winding point, thereby limiting the eccentricity of the metal strip and achieving the anti-eccentricity function.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses an anti-eccentric winding device.

[0031] Reference Figure 1 and Figure 2 An anti-eccentric winding device includes a mounting rod 1, a clamping plate 2, a main mounting nut 3, a through block 4, a first bolt assembly 5, and a second bolt assembly 6. The clamping plate 2 is a long strip-shaped rectangular plate. An installation position is opened in the middle of the width direction of the clamping plate 2. The installation positions are evenly distributed at equal intervals along the length direction of the clamping plate 2. The number of installation positions is odd and greater than three. In this embodiment, the number of installation positions is seven. The installation position located in the middle has an opening for the mounting rod 1 to pass through and install. The three installation positions located on one side of the mounting rod 1 are designated as the first installation positions 21 for the through block 4 and the first bolt assembly 5 to be installed. The through block 4 is fixed to the clamping plate 2 by the first bolt assembly 5. The three installation positions located on the other side of the mounting rod 1 are designated as the second installation positions 22 for the second bolt assembly 6 to be installed.

[0032] There are two clamping plates 2, which are spaced apart along the axial direction of the mounting rod 1. The through block 4 is clamped between the two clamping plates 2. A limiting screw head 11 is provided at one end of the mounting rod 1. The main mounting nut 3 is threaded onto the mounting rod 1. The two clamping plates 2 are clamped and fixed between the limiting screw head 11 and the main mounting nut 3.

[0033] Mounting rod 1 is used to fix the entire device to the equipment. The end of mounting rod 1 away from the limiting screw head 11 has an external thread. Two secondary mounting nuts 7 are threaded on the side of the main mounting nut 3 away from the clamping plate 2. A washer 8 is clamped between the main mounting nut 3 and the clamping plate 2, and between the main mounting nut 3 and the secondary mounting nuts 7. When installing mounting rod 1, different installation methods can be adopted depending on the situation on the equipment. In this embodiment, the main method is to have mounting rod 1 pass through the plate on the equipment for the installation of the anti-eccentric winding device, and the two secondary mounting nuts 7 are respectively set on both sides of the plate on the equipment for clamping and fixing.

[0034] When the equipment only has holes for mounting rod 1, mounting rod 1 can be directly screwed into the equipment. Then, only one secondary mounting nut 7 needs to be set. The secondary mounting nut 7 is rotated in the opposite direction to abut against the equipment to reinforce mounting rod 1.

[0035] The first bolt assembly 5 includes a first screw 51 and a first nut 52. The first mounting position 21 also has a hole for the first screw 51 to pass through. The through block 4, which is clamped between two clamping plates 2, is penetrated by the first screw 51 and is provided with a limiting structure to control the rotation of the through block 4 relative to the first screw 51. In this embodiment, the through block 4 and the first screw 51 are threaded together to form the limiting structure. Furthermore, the clamping plates 2 and the first screw 51 can also be threaded together.

[0036] The aforementioned through-hole block 4 has an exposed notch 41 in the middle, thereby exposing part of the first screw 51.

[0037] Reference Figure 3 and Figure 4 In another embodiment, the first screw 51 may not be directly connected to the through block 4, and the clamping plate 2 has irregular protrusions 91. The through block 4 has a matching insertion hole 92 for the protrusions 91 to be inserted. In this embodiment, the protrusions 91 are square pillars and the insertion holes 92 are square holes. The protrusions 91 and the insertion holes 92 cooperate to form the above-mentioned limiting structure. The first screw 51 restricts the through block 4 from detaching from the clamping plate 2, and the limiting structure controls the rotation of the through block 4 relative to the first screw 51. In a further embodiment, the first bolt assembly 5 can also be removed. The through block 4 directly achieves all the functions of preventing detachment and preventing rotation through the limiting structure. In yet another embodiment, the first bolt assembly 5 can also be retained, and the through block 4 has a semi-groove 42 for the first screw 51 to be inserted. The position of the through block 4 is positioned by the semi-groove 42, and then the two clamping plates 2 are clamped. The protrusions 91 are inserted into the insertion holes 92 to restrict the rotation of the through block 4, which facilitates installation.

[0038] Reference Figure 2The through block 4 has a limiting hole 43 for the metal strip to pass through. The limiting hole 43 passes straight through the through block 4. In this embodiment, the limiting hole 43 is opened on the side wall of the through block 4 facing the mounting rod 1, and the limiting hole 43 passes through the through block 4 in a direction away from the mounting rod 1. A supporting suspension block 44 is suspended on the side of the through block 4 away from the mounting rod 1. The direction of the supporting suspension block 44 is consistent with the direction of the limiting hole 43. The supporting suspension block 44 is located below the limiting hole 43 and supports the metal strip. The supporting suspension block 44 has a limiting groove 45 for the metal strip to pass through. The bottom of the limiting groove 45 is on the same plane as one of the holes of the limiting hole 43.

[0039] Reference Figure 1 The second bolt assembly 6 includes a mating block 61, a second screw 62, and a second nut 63. The mating block 61 is also clamped between the two clamping plates 2. The second screw 62 passes through the two clamping plates 2 and the mating block 61 and is fastened by the second nut 63. The dimension of the mating block 61 along the axial direction of the second screw 62 is the same as the dimension of the through block 4 along the axial direction of the first screw 51. In actual use, the mating block 61 can be composed of several nuts.

[0040] The aforementioned mating block 61 can also be fixed between the clamping plates 2 using the same installation method as the through block 4. That is, the mating block 61 also has an insertion hole 92 that mates with the protrusion 91, so that the clamping plate 2 is completely symmetrical to the two sides of the mounting rod 1, which facilitates installation.

[0041] When the clamping plate 2, the through block 4, and the mating block 61 all use the connection method of the protrusion 91 and the insertion hole 92, the first bolt assembly 5 and the second bolt assembly 6 are no longer installed. Only the through block 4 and the mating block 61 are retained. The first mounting position 21 and the second mounting position 22 are no longer opened. Alternatively, the implementation method in which the insertion hole 92 is opened on the clamping plate 2 is adopted. The first mounting position 21 and the second mounting position 22 are only opened with the insertion hole 92.

[0042] The implementation principle of the anti-eccentric winding device in this application embodiment is as follows: the metal strip enters the winding equipment, and then the metal strip passes through the limiting hole 43 on the through block 4 and is wound onto the corresponding rotating shaft. The metal strip and the flexible graphite strip are wound alternately to form the corresponding graphite winding pad 8. During this process, the metal strip is always restricted by the through block 4 to be in an accurate position.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
