Description

[0002] The twisting equipment, also called a stranding machine, is used for producing ropes, such as steel wire ropes. The twisting equipment requires a wire spool holder for wire feeding. The wire spool holder generally includes a wire spool support and an I-beam wheel. The wire spool holder carrying the I-beam wheel is driven by a motor to rotate, and wire feeding is achieved under the rotation of the I-beam wheel. The traditional I-beam wheel is usually fixed on the wire spool support, resulting in the inability to replace the specifications of the I-beam wheel and the incapability of adapting to the production of ropes with other specifications. Therefore, the existing wire spool holder realizes the detachable connection between the I-beam wheel and the wire spool support through a pneumatic structure to facilitate the replacement of I-beam wheels with different specifications. However, in the existing pneumatic structure, the piston rings sleeved on the pistons are usually made of steel or cast iron materials. In order to reduce the wear of the piston rings, lubricating oil channels need to be machined in a narrow space, and oil needs to be added regularly and frequently.

There is no limitation herein.
[0047] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present disclosure, "a plurality" means two or more unless otherwise specifically defined.
[0048] The following will describe the embodiments of the present utility model with reference to the accompanying drawings.
[0049] Please refer to Figure 1 , the embodiments of the present disclosure provide a pneumatic wire reel stand for a twisting device. The twisting device is used to twist ropes, such as steel ropes. Please also refer to Figure 2 and Figure 3 , the pneumatic wire reel stand for the twisting device includes a wire reel support 11, a wire pay-off reel 12, a first cylinder assembly 13, and a second cylinder assembly 14. The wire reel support 11 adopts a circular frame structure. The wire pay-off reel 12 is arranged inside the wire reel support 11. The wire pay-off reel 12 adopts a spool structure, and the axis of the wire pay-off reel 12 is perpendicular to the axis of the wire reel support 11. The first cylinder assembly 13 is arranged on one side of the wire pay-off reel 12 and connected to the wire reel support 11. The first cylinder assembly 13 rotatably abuts against one side of the wire pay-off reel 12, and the first piston ring 135 on the first cylinder assembly 13 is a self-lubricating piston ring. The second cylinder assembly 14 is arranged on the other side of the wire pay-off reel 12 and connected to the wire reel support 11. The second cylinder assembly 14 rotatably abuts against the other side of the wire pay-off reel 12, and the second piston ring 145 on the second cylinder assembly 14 is a self-lubricating piston ring.
[0050] In the pneumatic wire spool holder for the above-mentioned twisting equipment, by arranging the wire pay-off wheel 12 between the first cylinder assembly 13 and the second cylinder assembly 14, the first cylinder assembly 13 and the second cylinder assembly 14 are abutted against the wire pay-off wheel 12 to clamp the wire pay-off wheel 12. At the same time, the wire pay-off wheel 12 can rotate relative to the first cylinder assembly 13 and the second cylinder assembly 14, so as to facilitate the wire pay-off wheel 12 to rotate for wire pay-off. Moreover, the first piston ring 135 of the first cylinder assembly 13 and the second piston ring 145 of the second cylinder assembly 14 both adopt self-lubricating piston rings, thus achieving the effect of automatic lubrication without the operator regularly adding lubricating oil. In this way, the first cylinder assembly 13 and the second cylinder assembly 14 hold and clamp the wire pay-off wheel 12 to facilitate the disassembly and replacement of the wire pay-off wheel 12. At the same time, by adopting self-lubricating piston rings for both the first piston ring 135 and the second piston ring 145, there is no need to regularly add lubricating oil, nor to open lubricating oil channels, reducing the production cost of the pneumatic wire spool holder and the trouble of frequent oiling, and extending the service life.
[0051] Please refer to Figure 4 and Figure 5 , in some embodiments, the first piston ring 135 and the second piston ring 145 have the same structure, and the first piston ring 135 includes a first metal skeleton 1351 and a first self-lubricating layer 1352, the first self-lubricating layer 1352 is fixed to the outer side of the first metal skeleton 1351, the second piston ring 145 includes a second metal skeleton 1451 and a second self-lubricating layer 1452, the second self-lubricating layer 1452 is fixed to the outer side of the second metal skeleton 1451, the first metal skeleton 1351 and the second metal skeleton 1451 are made of steel or cast iron materials, and the first self-lubricating layer 1352 and the second self-lubricating layer 1452 are made of self-lubricating rubber materials or self-lubricating silicone rubber materials.
[0052] In this way, the self-lubricating piston ring not only maintains the rigidity and elasticity of the original steel or cast iron material, but also realizes the automatic lubrication function of the self-lubricating piston ring through the self-lubricating layer and is more wear-resistant.
[0053] In this embodiment, the self-lubricating layer is fixed to the outer peripheral surface of the metal skeleton by bonding, or the self-lubricating layer is fixed to the outer peripheral surface of the metal skeleton by hot melting. Specifically, both the self-lubricating layer and the metal skeleton layer are in a ring structure.
[0054] Please refer to Figure 2, in some embodiments, the first cylinder assembly 13 further includes a first cylinder block 131, a first piston 132 and a first central shaft 133. The interior of the first cylinder block 131 is configured with a first piston chamber 134. The first piston 132 is movably received in the first piston chamber 134. A first piston ring 135 is sleeved on the first piston 132 and abuts against the wall of the first piston chamber 134. The first piston 132 is rotatably sleeved on the first central shaft 133. One end of the first central shaft 133 extends out of the first piston chamber 134 and abuts against one side of the wire pay-off wheel 12, and the other end of the first central shaft 133 is rotatably connected to the first cylinder block 131.
[0055] Thus, by injecting gas into the first piston chamber 134, the first piston 132 is driven to move along the axial direction of the first central shaft 133 in the first piston chamber 134. The first piston 132 drives the side of the first central shaft 133 that abuts against the wire pay-off wheel 12, and cooperates with the second cylinder assembly 14 on the other side of the wire pay-off wheel 12 to clamp the wire pay-off wheel 12, and the wire pay-off wheel 12 can rotate relative to the wire spool bracket 11 to facilitate wire pay-off.
[0056] In this embodiment, the first piston 132 and the first central shaft 133 are rotatably connected through a bearing.
[0057] Please refer to Figure 2 , in some embodiments, the first central shaft 133 includes a first shaft body 1331, a first bearing seat 1332 and a first elastic member 1333. The first piston 132 is rotatably sleeved on the first shaft body 1331. One end of the first shaft body 1331 extends out of the first piston chamber 134 and abuts against one side of the wire pay-off wheel 12. The first bearing seat 1332 is connected to the other end of the first shaft body 1331. The first shaft body 1331 is rotatably connected to the first cylinder block 131 through the first bearing seat 1332. One end of the first elastic member 1333 is connected to the first shaft body 1331, and the other end of the first elastic member 1333 is connected to the first bearing seat 1332; wherein, when the first shaft body 1331 rotates, it drives the first elastic member 1333 to rotate synchronously, and the elastic force released by the first elastic member 1333 is used to drive the first shaft body 1331 to abut against one side of the wire pay-off wheel 12. Exemplarily, the first elastic member 1333 can be a spring.
[0058] In use, first, the first shaft body 1331 is driven by the first elastic member 1333 to abut against one side of the wire pay-off wheel 12, and then gas is injected into the first piston chamber 134 to drive the first piston 132 to move along the axial direction of the first central axis 133 in the first piston chamber 134, so as to lock the first central axis 133 that abuts against one side of the wire pay-off wheel 12 through the first piston 132, thereby ensuring the clamping stability. In this way, by utilizing the elasticity of the first elastic member 1333, the pre-fixation of the wire pay-off wheel 12 can be realized first, and then the pre-fixed wire pay-off wheel 12 can be locked, thus realizing the fixation of the wire pay-off wheel. This fixation method is more convenient and is conducive to the operator performing the installation or disassembly operation of the wire pay-off wheel 12.
[0059] In this embodiment, a first receiving groove is formed on the first shaft body 1331, and one end of the first elastic member 1333 is inserted into the first receiving groove, so as to reduce the space occupied by the first elastic member 1333 and ensure that the first elastic member 1333 only elastically deforms in the axial direction of the first shaft body 1331.
[0060] Furthermore, the number of the first receiving grooves and the first elastic members 1333 is multiple. The multiple first receiving grooves are circumferentially spaced with the axis of the first shaft body 1331 as the axis, and each first elastic member 1333 is inserted into a corresponding receiving groove.
[0061] Please refer to Figure 2 , in some embodiments, a first sealing ring 137 is further sleeved on the outer periphery of the first piston 132. The first sealing ring 137 is spaced from the first piston ring 135, and the first sealing ring 137 is used to realize the seal between the first piston 132 and the wall of the first piston chamber 134.
[0062] Please refer to Figure 3 , in some embodiments, the second cylinder assembly 14 includes a second cylinder base 141, a second piston 142 and a second central axis 143. The inside of the second cylinder base 141 is configured with a second piston chamber 144. The second piston 142 can be movably received in the second piston chamber 144. The second piston ring 145 is sleeved on the second piston 142 and abuts against the wall of the second piston chamber 144. The second piston 142 is rotatably sleeved on the second central axis 143. One end of the second central axis 143 abuts against the other side of the wire pay-off wheel 12, and the other end of the second central axis 143 is rotatably connected to the second cylinder base 141.
[0063] Thus, by injecting gas into the second piston chamber 144, the second piston 142 is driven to move along the axial direction of the second central axis 143 within the second piston chamber 144. The second piston 142 drives the second central axis 143 to abut against one side of the wire pay-off wheel 12, and cooperates with the first cylinder assembly 13 to clamp the wire pay-off wheel 12. The wire pay-off wheel 12 can rotate relative to the wire spool bracket 11 to facilitate wire pay-off.
[0064] In this embodiment, the first piston 132 and the first central axis 133 are rotatably connected through a bearing.
[0065] Please refer to Figure 3 , in some embodiments, the second central axis 143 includes a second shaft body 1431, a second bearing seat 1432, and a second elastic member 1433. The second piston 142 is rotatably sleeved on the second shaft body 1431. One end of the second shaft body 1431 extends out of the second piston chamber 144 and abuts against the other side of the wire pay-off wheel 12. The second bearing seat 1432 is connected to the other end of the second shaft body 1431. The second shaft body 1431 is rotatably connected to the second cylinder seat 141 through the second bearing seat 1432. One end of the second elastic member 1433 is connected to the second shaft body 1431, and the other end of the second elastic member 1433 is connected to the second bearing seat 1432. Wherein, when the second shaft body 1431 rotates, it drives the second elastic member 1433 to rotate synchronously, and the elastic force released by the second elastic member 1433 is used to drive the second shaft body 1431 to abut against the other side of the wire pay-off wheel 12. Exemplarily, the second elastic member 1433 can be a spring.
[0066] During use, first, the second elastic member 1433 is used to drive the second shaft body 1431 to abut against the other side of the wire pay-off wheel 12, and then gas is injected into the second piston chamber 144 to drive the second piston 142 to move along the axial direction of the second central axis 143 within the second piston chamber 144, so as to lock the second central axis 143 that abuts against the other side of the wire pay-off wheel 12 through the second piston 142, thereby ensuring the stability of clamping. Thus, by utilizing the elasticity of the second elastic member 1433, the pre-fixation of the wire pay-off wheel 12 can be realized first, and then the pre-fixed wire pay-off wheel 12 can be locked, thereby realizing the fixation of the wire pay-off wheel. This fixation method is more convenient and is conducive to the operator performing the installation or disassembly operation of the wire pay-off wheel 12.
[0067] In this embodiment, a first receiving groove is formed on the first shaft body 1331, and one end of the first elastic member 1333 is inserted into the first receiving groove, so as to reduce the space occupied by the first elastic member 1333 and ensure that the first elastic member 1333 only elastically deforms in the axial direction of the first shaft body 1331.
[0068] Furthermore, the number of the first receiving grooves and the first elastic member 1333 is multiple, and the multiple first receiving grooves are arranged at intervals in the circumferential direction with the axis of the first shaft body 1331 as the axis, and each first elastic member 1333 is inserted into a corresponding receiving groove.
[0069] See also Figure 3 In some embodiments, the second cylinder assembly 14 further includes a portion of a damping assembly 146 connected to the reel support 11, and another portion of the damping assembly 146 is sleeved on the second cylinder seat 141, and the damping assembly 146 is used to adjust the resistance of the pay-off wheel 12 when it rotates.
[0070] In some embodiments, the first cylinder assembly 13 also includes a balancing member 136, which is mounted on the first cylinder seat 131 to balance the weight of the damping assembly 146, so that the weight layout of the pneumatic wire drum rack is more balanced, so that when the wire drum bracket 11 rotates under the drive of an external motor, the rotation of the pneumatic wire drum rack is more stable.
[0071] See also Figure 3 In some embodiments, a second sealing ring 147 is further sleeved on the outer periphery of the second piston 142 . The second sealing ring 147 and the second piston ring 145 are arranged at intervals. The second sealing ring 147 is used to achieve sealing between the second piston 142 and the cavity wall of the second piston cavity 144 .
[0072] The working principle of the pneumatic bobbin frame used in the above-mentioned twisting equipment is roughly as follows:
[0073] First, by external force, the first shaft 1331 and the second shaft 1431 are moved, and the distance between the first shaft 1331 and the second shaft 1431 can be adjusted under the action of the first elastic member 1333 and the second elastic member 1433, so as to adapt to and press against the pay-off wheels 12 of different specifications;
[0074] Then, the pay-off wheel 12 is placed between the first shaft 1331 and the second shaft 1431 , and the first shaft 1331 and the second shaft 1431 are lowered and clamped under the action of the elastic force released by the first elastic member 1333 and the second elastic member 1433 ;
[0075] Finally, gas is injected into the first piston chamber 134 and the second piston chamber 144 to lock the first piston 132 and the second piston 142 , thereby driving the first shaft body 1331 and the second shaft body 1431 to be locked, thereby fixing the pay-off wheel 12 .
