Description

Technical Field

[0001] This application relates to the technical field, and specifically relates to a slip ring, a slip shaft, and a method for balancing the tension of the slip ring of the slip shaft. Background Art

[0002] In the winding operation of industrial production, the slip shaft and the slip ring play a crucial role. The slip shaft is a key component commonly used in winding equipment, and its main function is to achieve stable winding of different materials, ensuring the smoothness of the winding process and the reliability of the winding quality. The slip ring, as the core component of the slip shaft, directly affects the performance of the slip shaft.

[0003] Currently, the common slip rings on the market have some significant limitations. The number of pistons used inside the slip ring is fixed, and the number of pistons needs to be adapted according to the tension of the winding diaphragm. This means that when winding diaphragms with different tension levels, it is necessary to replace the entire slip ring with a different number of pistons. This method is not only cumbersome to operate but also costly, greatly increasing the production and operation costs of enterprises.

[0004] In addition, the slip shaft usually consists of multiple slip rings. During the winding operation, in order to improve the winding quality of the diaphragm, it is necessary to ensure that the tensions of each slip ring are as equal as possible. However, the existing technical means have great difficulties in adjusting the tensions of each slip ring, and it is difficult to achieve precise and convenient tension adjustment, which to a certain extent affects the winding effect and quality of the diaphragm.

[0005] In summary, the existing slip ring and slip shaft technologies have problems such as high cost and inconvenient tension adjustment in practical applications. Therefore, it is of great practical significance to develop a new type of slip ring, slip shaft, and a method for balancing the tension of the slip ring of the slip shaft. Summary of the Invention

[0006] In order to solve the technical problems in the existing technology, this application provides a slip ring, a slip shaft, and a method for balancing the tension of the slip ring of the slip shaft.

[0007] The slip ring, slip shaft, and method for balancing the tension of the slip ring of the slip shaft provided by this application adopt the following technical solutions: A slip ring, comprising: A fixed sleeve; A clamping mechanism, the clamping mechanism comprising a beveled ring body, a bearing seat, a plurality of long wedge blocks and an elastic ring, the beveled ring body being movably sleeved on one end of the fixed sleeve, a plurality of beveled grooves being provided on the outer side wall of the beveled ring body, the bottom surface of the beveled grooves being an inclined surface, the bearing seat being coaxially rotatably connected with the fixed sleeve, each of the long wedge blocks being slidably disposed in the corresponding beveled groove and abutting against the bottom surface of the beveled groove and abutting against the bearing seat, and the elastic ring being sleeved outside each of the long wedge blocks; and, The adjusting mechanism comprises a plurality of gas cylinders, a plurality of pistons and an adjusting sleeve, each of the gas cylinders is fixed to the fixed sleeve, one end of each of the pistons is sealingly and slidably arranged in the gas cylinder, the other end of each of the pistons can abut against the beveled ring body and push the beveled ring body to move, the adjusting sleeve is rotatably sleeved on the fixed sleeve, a blocking plate is formed on the adjusting sleeve, and when the adjusting sleeve is rotated to different positions, the blocking plate can reach between different numbers of pistons and the beveled ring body.

[0008] By adopting the above technical solution, the number of pistons involved in the work can be adjusted by rotating the adjustment sleeve, which greatly simplifies the operation process, improves work efficiency, and reduces the time loss caused by replacing the differential ring. It avoids the purchase cost caused by frequent replacement of the differential ring, reduces the investment of the enterprise in the winding equipment components, effectively saves the production and operation costs of the enterprise, and improves the economic benefits of the enterprise. At the same time, the number of pistons used can be flexibly adjusted to adapt to diaphragms with different tensions, so that the differential ring is suitable for winding operations with a variety of different tension requirements, expanding its scope of application and enhancing the versatility and flexibility of the equipment.

[0009] Preferably, the clamping mechanism further comprises a limit bearing, the inner ring of the limit bearing is fixed to the fixed sleeve, and the outer ring of the limit bearing is coaxially fixedly connected to the bearing seat.

[0010] By adopting the above technical solution, the inner ring of the limit bearing is fixed to the fixed sleeve, and the outer ring is coaxially fixedly connected to the bearing seat, so that the connection between the bearing seat and the fixed sleeve is more stable. During the operation of the differential ring, especially when the air shaft drives the fixed sleeve to rotate and the piston drives the bevel ring body and other components to move, it can ensure that the bearing seat maintains a stable coaxial position relationship relative to the fixed sleeve, reduce the structural instability factors caused by relative shaking or offset between components, and thus improve the working stability and reliability of the entire differential ring.

[0011] Preferably, an annular groove is provided on the outer side wall of each of the long wedge blocks, and the elastic ring is arranged in the annular groove of each of the long wedge blocks.

[0012] By adopting the above technical solution, the annular groove plays a role in positioning and restraining the elastic ring, enabling the elastic ring to be stably arranged on the long wedge block, and preventing the elastic ring from shifting or falling off during the operation of the slip ring. At the same time, the presence of the elastic ring can also limit the lateral movement of the long wedge block to a certain extent, ensuring that the position of the long wedge block in the inclined groove is relatively stable, so that when it is pushed by the bevel-cut ring body, it can move more accurately along the bottom surface of the inclined groove and extend outwards to abut against the drum, improving the reliability and stability of the clamping mechanism.

[0013] Preferably, a plurality of air holes are formed in the fixed sleeve, and the air holes are in one-to-one correspondence and communication with the air inlet ends of the air cylinders.

[0014] By adopting the above technical solution, the air holes are in one-to-one correspondence and communication with the air inlet ends of the air cylinders, and can smoothly transmit the gas filled into the air shaft to each air cylinder. When the air shaft is inflated, the gas enters the air cylinder through the air holes, pushing the piston in the air cylinder to extend, providing power for the piston. After the piston extends, it pushes the bevel-cut ring body, and then drives the long wedge block to abut against the drum, realizing the clamping process. Therefore, the setting of the air holes ensures that the gas can effectively act on the piston, providing a necessary power source for the clamping and operation of the slip ring, and is an important basis for the slip ring to realize its normal function.

[0015] Preferably, two sealing grooves are further formed in the fixed sleeve, the two sealing grooves are respectively located on both sides of the air inlet of the air hole, and two sealing rings are respectively arranged in the two sealing grooves and are used for sleeving on the air shaft inserted in the fixed sleeve.

[0016] By adopting the above technical solution, the sealing rings are sleeved on the air shaft inserted in the fixed sleeve and are located in the sealing grooves on both sides of the air inlet of the air hole. When the air shaft is inflated, the sealing rings can effectively prevent the gas from leaking from the connection between the fixed sleeve and the air shaft, ensuring that the inflated gas can smoothly enter the air cylinder through the air holes and push the piston to work. This ensures that sufficient air pressure can be maintained in the air cylinder, enabling the piston to extend normally and push the bevel-cut ring body and the long wedge block to realize the clamping of the drum. It avoids insufficient power of the piston caused by gas leakage, which affects the normal operation of the slip ring.

[0017] Preferably, a limiting groove is formed on the inner side wall of the adjusting sleeve, the adjusting mechanism further includes a snap ring, the snap ring is clamped in the limiting groove, the snap ring abuts against one side of the fixed sleeve, and the other side of the fixed sleeve abuts against the blocking plate.

[0018] By adopting the above technical solution, the snap ring is clamped in the limit groove on the inner side wall of the adjusting sleeve, and the snap ring abuts against one side of the fixed sleeve, and the other side of the fixed sleeve abuts against the blocking plate on the adjusting sleeve. Such a structural arrangement limits the axial position of the adjusting sleeve on the fixed sleeve, prevents the adjusting sleeve from moving axially unnecessarily during operation, ensures that the adjusting sleeve can rotate stably on the fixed sleeve, and thus ensures that the adjusting mechanism can work properly and accurately adjust the number of pistons participating in the work.

[0019] Preferably, an installation hole is further formed on the outer side wall of the fixed sleeve, and a plurality of positioning holes corresponding to the installation hole are formed on the side wall of the adjusting sleeve; the adjusting mechanism further includes a positioning assembly, and the positioning assembly includes a positioning elastic member and a positioning ball. One end of the positioning elastic member is fixed in the installation hole, the positioning ball is partially slidably disposed in the installation hole, the other end of the positioning elastic member is connected to the positioning ball and is used to push the positioning ball to partially enter one of the positioning holes. When the positioning ball enters different positioning holes, the blocking plate can reach between different numbers of pistons and the beveled ring body.

[0020] By adopting the above technical solution, the arrangement of the positioning elastic member and the positioning ball ensures that the position of the adjusting sleeve can be stably maintained after adjustment, prevents the adjusting sleeve from rotating due to factors such as vibration and external force during the operation of the slip ring and changing the number of pistons working, ensures the stability of the working state of the slip ring, and further ensures the stability and reliability of the winding or unwinding operation, and avoids the winding quality problems caused by the unstable number of pistons working.

[0021] Preferably, an observation hole is further formed on the outer side wall of the adjusting sleeve, and a plurality of digital marks are further formed on the outer side wall of the fixed sleeve. When the positioning ball enters different positioning holes, different digital marks can reach the position of the observation hole.

[0022] By adopting the above technical solution, when the positioning ball enters different positioning holes, the adjusting sleeve rotates to different positions. At this time, different digital marks on the outer side wall of the fixed sleeve will reach the position of the observation hole on the outer side wall of the adjusting sleeve. The operator can directly see the corresponding digital mark through the observation hole, so as to intuitively understand the current position of the adjusting sleeve and the number of pistons participating in the work at this time. This intuitive display method enables the operator to quickly and accurately obtain the adjustment state of the slip ring without complicated operations or additional detection equipment, improving the convenience and efficiency of the operation.

[0023] The present application also provides a slip shaft, which includes a pneumatic shaft and a plurality of slip rings. The pneumatic shaft is hollow, and a plurality of perforations are formed on the pneumatic shaft. The fixed sleeve of the slip ring is sleeved on the pneumatic shaft, and the air holes of the slip ring communicate with the corresponding perforations on the pneumatic shaft.

[0024] By adopting the above technical solution, the communication design between the perforations on the pneumatic shaft and the air holes of the slip ring enables the gas filled in the pneumatic shaft to be smoothly transmitted into the air cylinder of the slip ring, providing power for the piston, ensuring the power requirements for the slip ring to clamp the winding drum and perform winding or unwinding operations, and being the key basis for the slip shaft to achieve its normal functions.

[0025] The present application also provides a method for balancing the tension of the slip rings of a slip shaft, which is applicable to the slip shaft described above and includes the following steps: S1. Respectively install a plurality of winding drums on each slip ring, and set a tension detection device on each slip ring, and rotate the driving member to drive the pneumatic shaft to rotate; S2. Obtain the tension between each slip ring on the pneumatic shaft and the winding drum detected by the tension detection device; S3. If the difference in the tension between each slip ring and the winding drum is greater than a preset threshold value, stop the driving member, and then increase the number of effective pistons of the slip ring with a smaller tension or decrease the number of effective pistons of the slip ring with a larger tension, so that the difference in the tension between each slip ring and the winding drum is less than the preset threshold value.

[0026] By adopting the above technical solution, by setting a tension detection device on each slip ring, the tension data between the slip ring and the winding drum can be obtained in real time. When the difference in the tension between each slip ring and the winding drum is greater than the preset threshold value, the number of effective pistons is adjusted in time to make the difference in the tension less than the preset threshold value. In this way, it can be ensured that the tension received by each winding drum during the winding process is uniform, avoiding problems such as material deformation, wrinkles, and fractures caused by uneven tension, thereby ensuring the winding quality and improving the product qualification rate. This method can timely detect and solve the problem of uneven tension between the slip rings, avoiding additional stress and wear on the entire slip shaft and winding equipment caused by abnormal tension of individual slip rings. By adjusting the number of effective pistons to balance the tension, it helps to maintain the stable operation of the equipment, extend the service life of the equipment, reduce equipment failures and downtime, and improve the reliability and stability of the equipment.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. Compared with the traditional way of replacing the entire slip ring when winding diaphragms with different tensions, this technical solution can adjust the number of pistons participating in the work by rotating the adjusting sleeve, greatly simplifying the operation process, improving work efficiency, and reducing the time loss caused by replacing the slip ring. It avoids the purchase cost due to frequent overall replacement of the slip ring, reduces the investment of the enterprise in the components of the winding equipment, effectively saves the production and operation cost of the enterprise, and improves the economic benefits of the enterprise. At the same time, it can flexibly adjust the number of pistons used to adapt to diaphragms with different tension sizes, making this slip ring applicable to various winding operations with different tension requirements, expanding its application range, and enhancing the versatility and flexibility of the equipment.

[0028] 2. The setting of the positioning elastic part and the positioning glass bead ensures that the position of the adjusting sleeve can be stably maintained after adjustment, preventing the adjusting sleeve from rotating due to factors such as vibration and external force during the operation of the slip ring, thus changing the number of pistons in work, ensuring the stability of the working state of the slip ring, and further ensuring the stability and reliability of the winding or unwinding operation, and avoiding the winding quality problems caused by the unstable number of pistons in work.

[0029] 3. When the positioning glass bead enters different positioning holes, the adjusting sleeve rotates to different positions. At this time, different digital marks on the outer wall of the fixed sleeve will reach the observation hole position on the outer wall of the adjusting sleeve. The operator can directly see the corresponding digital marks through the observation hole, so as to intuitively understand the current position of the adjusting sleeve and the number of pistons participating in the work at this time (because different positions of the adjusting sleeve correspond to different numbers of pistons participating in the work). This intuitive display method enables the operator to quickly and accurately obtain the adjustment state of the slip ring without complex operations or additional detection equipment, improving the convenience and efficiency of the operation.

[0030] 4. By setting a tension detection device on each slip ring, the tension data between the slip ring and the reel can be obtained in real time. When the tension difference between each slip ring and the reel is greater than the preset threshold, the number of effective pistons is adjusted in time to make the tension difference less than the preset threshold. This can ensure that the tension received by each reel during the winding process is uniform, avoiding problems such as material deformation, wrinkles, and fractures caused by uneven tension, thus ensuring the quality of the winding and improving the qualified rate of products. This method can timely detect and solve the problem of uneven tension between slip rings, avoiding the additional stress and wear on the entire slip shaft and winding equipment caused by abnormal tension of individual slip rings. By adjusting the number of effective pistons to balance the tension, it helps to maintain the stable operation of the equipment, extend the service life of the equipment, reduce equipment failures and downtime, and improve the reliability and stability of the equipment.

[0032] The following will further elaborate on this application in conjunction with the attached Figures 1-12 drawings.

[0033] An embodiment of this application discloses a slip ring 1. Refer to Figures 1-8 , the slip ring 1 includes a fixed sleeve 11, a clamping mechanism 12 and an adjusting mechanism 13.

[0034] The clamping mechanism 12 includes an inclined cutting ring body 121, a bearing seat 122, a plurality of long wedges 123 and an elastic ring 124. The inclined cutting ring body 121 is movably sleeved on one end of the fixed sleeve 11. A plurality of inclined grooves are formed on the outer side wall of the inclined cutting ring body 121. The bottom surface of the inclined groove is an inclined surface. The bearing seat 122 is coaxially and rotatably connected to the fixed sleeve 11. Each long wedge 123 is respectively slidably disposed in the corresponding inclined groove and abuts against the bottom surface of the inclined groove. The side surface of each long wedge 123 abuts against the bearing seat 122. The elastic ring 124 is sleeved outside each long wedge 123.

[0035] The adjusting mechanism 13 includes a plurality of air cylinders 131, a plurality of pistons 132 and an adjusting sleeve 133. Each air cylinder 131 is fixed to the fixed sleeve 11. One end of each piston 132 is hermetically and slidably disposed in the air cylinder 131. The other end of each piston 132 can abut against the inclined cutting ring body 121 and push the inclined cutting ring body 121 to move. The adjusting sleeve 133 is rotatably sleeved on the fixed sleeve 11. A blocking plate 1331 is formed on the adjusting sleeve 133. When the adjusting sleeve 133 rotates to different positions, the blocking plate 1331 can reach between different numbers of pistons 132 and the inclined cutting ring body 121.

[0036] The working process of the above technical solution is as follows: (1) Installation and initial state: First, install the slip ring 1 on the air shaft 2, and then install the reel 3 on the slip ring 1. At this time, each component of the slip ring is in the initial position, and no power input and adjustment operations are performed.

[0037] (2) Clamping process: The air shaft 2 is inflated, and the gas enters each air cylinder 131 of the slip ring 1, causing each piston 132 in the air cylinder 131 to extend under the action of gas pressure. The extended piston 132 pushes the beveled ring body 121 towards the bearing seat 122. Since the long wedge blocks 123 are arranged in the inclined grooves on the outer side wall of the beveled ring body 121 and the side surfaces of the long wedge blocks 123 are in contact with the bearing seat 122, each long wedge block 123 will be pushed when the beveled ring body 121 moves. Also, because the long wedge blocks 123 are blocked by the bearing seat 122 and cannot move horizontally, each long wedge block 123 will move along the inner bottom surface of the inclined groove and extend outwards, finally clamping tightly the reel 3, completing the clamping of the reel 3, and enabling the reel 3 to be stably installed on the slip ring 1.

[0038] (3) Rewinding or unwinding process: The air shaft 2 rotates, driving the fixed sleeve 11 to rotate. The fixed sleeve 11 drives each piston 132 to rotate together. Since there is friction between the piston 132 and the beveled ring body 121, this friction will drive the beveled ring body 121, each long wedge block 123 and the reel 3 to rotate together, thus realizing the rewinding or unwinding operation.

[0039] (4) Speed balancing process (when multiple slip rings are used): Since the bearing seat 122 is coaxially rotatably connected to the fixed sleeve 11, the whole composed of the beveled ring body 121, each long wedge block 123 and the reel 3 can rotate relative to the fixed sleeve 11, that is, they can have different rotational speeds. In the case of using multiple slip rings simultaneously, when the rotational speeds of some reels 3 are different, slipping will occur between the pistons 132 and the beveled ring body 121 of the corresponding slip rings. Through this slipping, the rotational speeds of each reel 3 are balanced, ensuring the stability and smoothness of the rewinding or unwinding process.

[0040] (5) Unwinding process: When the rewinding or unwinding process ends, the air supply to the air shaft 2 stops. Under the action of the elastic ring 124, each long wedge block 123 resets and disengages from the reel 3, and then the reel 3 is taken out.

[0041] (6) Piston quantity adjustment process: When it is necessary to rewind diaphragms with different tension magnitudes, rotate the adjusting sleeve 133. Since the blocking plate 1331 is formed on the adjusting sleeve 133, as the adjusting sleeve 133 rotates to different positions, the blocking plate 1331 can reach between different numbers of pistons 132 and the beveled ring body 121. When the blocking plate 1331 blocks between the piston 132 and the beveled ring body 121, this piston 132 cannot push the beveled ring body 121 to move, that is, this piston does not participate in the work, thus realizing the flexible change of the number of pistons 132 participating in the work according to actual needs to adapt to diaphragms with different tensions.

[0042] In addition, in order to prevent the blocking plate 1331 of the adjusting sleeve 133 from being blocked by the piston 132 and unable to rotate due to the fit between the piston 132 and the beveled ring body 121, the piston 132 can be pushed inward by the lever so that the piston 132 is not in the moving path of the blocking plate 1331, and then the adjusting sleeve 133 can be rotated.

[0043] The technical effects of the above technical solution include: (1) Solving the problem of cumbersome operation: Compared with the traditional method in which the differential ring needs to be replaced as a whole when winding diaphragms with different tensions, the present technical solution can adjust the number of pistons 132 involved in the work by rotating the adjustment sleeve 133, which greatly simplifies the operation process, improves work efficiency, and reduces the time loss caused by replacing the differential ring.

[0044] (2) Reduce costs: Avoid the purchase cost caused by frequent replacement of the slip ring, reduce the company's investment in winding equipment components, effectively save the company's production and operation costs, and improve the company's economic benefits.

[0045] (3) Wide range of applications: The number of pistons 123 used can be flexibly adjusted to adapt to diaphragms with different tensions, making the slip ring suitable for winding operations with a variety of different tension requirements, thereby expanding its scope of application and enhancing the versatility and flexibility of the equipment.

[0046] In one embodiment, see Figures 1-3 , the clamping mechanism 12 also includes a limit bearing 125, the inner ring of the limit bearing 125 is fixed to the fixed sleeve 11, and the outer ring of the limit bearing 125 is coaxially fixedly connected to the bearing seat 122. In this embodiment, the inner ring of the limit bearing 125 is fixed to the fixed sleeve 11, and the outer ring is coaxially fixedly connected to the bearing seat 122, so that the connection between the bearing seat 122 and the fixed sleeve 11 is more stable. During the operation of the differential ring, especially when the air shaft drives the fixed sleeve to rotate and the piston drives the bevel ring body and other components to move, it can ensure that the bearing seat 122 maintains a stable coaxial position relationship relative to the fixed sleeve 11, reduce the structural instability factors caused by the relative shaking or offset between the components, thereby improving the working stability and reliability of the entire differential ring.

[0047] In one embodiment, see Figures 1-3 The clamping mechanism 12 further includes a spacer sleeve 114 , which is coaxially fixed to the fixed sleeve 11 , and the inner ring of the limit bearing 125 is fixed to the spacer sleeve 114 .

[0048] In one embodiment, see Figures 1-3, annular grooves 1231 are formed on the outer side walls of the respective long wedge blocks 123, and the elastic rings 124 are arranged in the annular grooves 1231 of the respective long wedge blocks 123. In this embodiment, the annular grooves 1231 play a role in positioning and restricting the elastic rings, enabling the elastic rings to be stably arranged on the long wedge blocks and preventing the elastic rings from shifting or falling off during the operation of the slip ring. At the same time, the presence of the elastic rings can also limit the lateral movement of the long wedge blocks to a certain extent, ensuring the relative stability of the positions of the long wedge blocks in the inclined grooves, enabling them to move more accurately along the bottom surface of the inclined grooves and extend outwards to abut against the reel when pushed by the inclined cutting ring body, and improving the reliability and stability of the clamping mechanism.

[0049] In one embodiment, please refer to Figures 1-3 , a plurality of air holes 111 are formed in the fixed sleeve 11, and the air holes 111 are in one-to-one correspondence and communication with the air inlet ends of the air cylinders 131. In this embodiment, the air holes 111 are in one-to-one correspondence and communication with the air inlet ends of the air cylinders 131, and can smoothly transmit the gas filled into the air shaft to each air cylinder. When the air shaft is inflated, the gas enters the air cylinder through the air holes, pushing the piston in the air cylinder to extend out and providing power for the piston. After the piston extends out, it pushes the inclined cutting ring body, and then drives the long wedge block to abut against the reel, realizing the clamping process. Therefore, the setting of the air holes ensures that the gas can effectively act on the piston, provides a necessary power source for the clamping and operation of the slip ring, and is an important basis for the slip ring to realize its normal function.

[0050] In one embodiment, please refer to Figures 1-3 , two sealing grooves are further formed in the fixed sleeve 11, the two sealing grooves are respectively located on both sides of the air inlet of the air hole 111, and two sealing rings 115 are respectively arranged in the two sealing grooves and are used for sleeving on the air shaft 2 inserted in the fixed sleeve 11. In this embodiment, the sealing rings 115 are sleeved on the air shaft 2 inserted in the fixed sleeve 11 and are located in the sealing grooves on both sides of the air inlet of the air hole 111. When the air shaft is inflated, the sealing rings can effectively prevent the gas from leaking from the connection between the fixed sleeve and the air shaft, ensuring that the inflated gas can smoothly enter the air cylinder through the air holes and push the piston to work. This ensures that sufficient air pressure can be maintained in the air cylinder, enabling the piston to extend out normally and push the inclined cutting ring body and the long wedge block to realize the clamping of the reel. It avoids insufficient power of the piston caused by gas leakage and affects the normal operation of the slip ring.

[0051] In one embodiment, please refer to Figures 1-3, a limiting groove 1332 is formed on the inner side wall of the adjusting sleeve 133. The adjusting mechanism 13 further includes a snap spring 134 which is clamped in the limiting groove 1332. The snap spring 134 abuts against one side of the fixed sleeve 11, and the other side of the fixed sleeve 11 abuts against the blocking plate 1331. In this embodiment, the snap spring 134 is clamped in the limiting groove 1332 on the inner side wall of the adjusting sleeve 133, and the snap spring 134 abuts against one side of the fixed sleeve 11. The other side of the fixed sleeve 11 abuts against the blocking plate 1331 on the adjusting sleeve 133. Such a structural arrangement limits the axial position of the adjusting sleeve 133 on the fixed sleeve 11, preventing unnecessary axial movement of the adjusting sleeve during operation, ensuring that the adjusting sleeve can rotate stably on the fixed sleeve, and thus ensuring that the adjusting mechanism can work properly and accurately adjust the number of pistons participating in the work.

[0052] In one embodiment, please refer to Figures 1-3 , an installation hole 112 is further formed on the outer side wall of the fixed sleeve 11, and a plurality of positioning holes 1333 corresponding to the installation hole 112 are formed on the side wall of the adjusting sleeve 133; the adjusting mechanism 13 further includes a positioning component 135, and the positioning component 135 includes a positioning elastic member 1351 and a positioning ball 1352. One end of the positioning elastic member 1351 is fixed in the installation hole 112, and the positioning ball 1352 is partially slidably arranged in the installation hole 112. The other end of the positioning elastic member 1351 is connected to the positioning ball 1352 and is used to push the positioning ball 1352 to partially enter one of the positioning holes 1333. When the positioning ball 1352 enters different positioning holes 1333, the blocking plate 1331 can reach between different numbers of pistons 132 and the beveled ring body 121.

[0053] In this embodiment, when it is necessary to adjust the number of pistons 132 participating in the work according to the tension of the winding diaphragm, an external force acts on the adjusting sleeve 133 to make it rotate around the fixed sleeve 11. During the rotation, the positioning ball 1352 is squeezed by the side wall of the adjusting sleeve 133, overcomes the elastic force of the positioning elastic member 1351, and gradually exits from the current positioning hole 1333 and slides in the installation hole 112. When the adjusting sleeve 133 rotates to a suitable position so that the positioning ball 1352 is aligned with another positioning hole 1333, the elastic force of the positioning elastic member 1351 pushes the positioning ball 1352 to partially enter the new positioning hole 1333 to complete the positioning of the adjusting sleeve 133. At this time, the blocking plate 1331 on the adjusting sleeve 133 reaches a new position, which can block between different numbers of pistons 132 and the beveled ring body 121, thereby changing the number of pistons 132 participating in the work to adapt to winding diaphragms with different tensions.

[0054] The arrangement of the positioning elastic member 1351 and the positioning glass bead 1352 ensures that the adjusting sleeve 133 can stably maintain its adjusted position, preventing the adjusting sleeve from rotating due to factors such as vibration and external forces during the operation of the slip ring, thus changing the working quantity of the piston. This ensures the stability of the working state of the slip ring, and further guarantees the stability and reliability of the winding or unwinding operation, avoiding winding quality problems caused by unstable piston working quantity.

[0055] In one embodiment, please refer to Figures 1-8 , an observation hole 1334 is further formed on the outer side wall of the adjusting sleeve 133, and a number of digital marks 113 are further formed on the outer side wall of the fixed sleeve 11. When the positioning glass bead 1352 enters different positioning holes 1333, different digital marks 113 can reach the position of the observation hole 1334. In this embodiment, when the positioning glass bead 1352 enters different positioning holes 1333, the adjusting sleeve 133 rotates to different positions. At this time, different digital marks 113 on the outer side wall of the fixed sleeve 11 will reach the position of the observation hole 1334 on the outer side wall of the adjusting sleeve 133. The operator can directly see the corresponding digital marks through the observation hole, so as to intuitively understand the current position of the adjusting sleeve and the number of pistons participating in the work at this time (because different positions of the adjusting sleeve correspond to different numbers of pistons participating in the work). This intuitive display method enables the operator to quickly and accurately obtain the adjustment state of the slip ring without complex operations or additional detection equipment, improving the convenience and efficiency of the operation.

[0056] Specifically, as Figure 4 shown, when the adjusting sleeve rotates to this position, the digital mark corresponding to the observation hole is 0, and at this time no piston moves; as Figure 5 shown, when the adjusting sleeve rotates to this position, the digital mark corresponding to the observation hole is 3, and 3 pistons can move; as Figure 6 shown, when the adjusting sleeve rotates to this position, the digital mark corresponding to the observation hole is 6, and 6 pistons can move; as Figure 7 shown, when the adjusting sleeve rotates to this position, the digital mark corresponding to the observation hole is 9, and 9 pistons can move; as Figure 8 shown, when the adjusting sleeve rotates to this position, the digital mark corresponding to the observation hole is 12, and 12 pistons can move.

[0057] Please refer to Figures 9-12, the present application also provides a slip shaft, including an air shaft 2 and a plurality of slip rings 1. The air shaft 2 is hollow, and a plurality of perforations 21 are formed on the air shaft 2. The fixed sleeve 11 of the slip ring 1 is sleeved on the air shaft 2, and the air holes 111 of the slip ring 1 communicate with the corresponding perforations 21 on the air shaft 2. In this embodiment, the communication design between the perforations 21 on the air shaft 2 and the air holes 111 of the slip ring 1 enables the gas filled in the air shaft to be smoothly transmitted into the air cylinder of the slip ring, providing power for the piston, ensuring the power requirements for the slip ring to clamp the winding drum and perform winding or unwinding operations, and is the key basis for the slip shaft to achieve normal functions.

[0058] The working process of this embodiment includes: (1) Installation stage: The fixed sleeves 11 of a plurality of slip rings 1 are sequentially sleeved on the air shaft 2 to complete the assembly of the slip shaft. Since the air shaft 2 is hollow and a plurality of perforations 21 are formed thereon, the air holes 111 in the fixed sleeve 11 of the slip ring 1 communicate with the corresponding perforations 21 on the air shaft 2, forming a gas passage between the internal space of the air shaft 2 and the air inlet end of the air cylinder 131 of the slip ring 1.

[0059] (2) Inflation stage: An inflation operation is performed on the air shaft 2, and the gas enters the hollow interior of the air shaft 2. Since the perforations 21 communicate with the air holes 111, the gas enters the air holes 111 of each slip ring 1 through the perforations 21 and then further enters the air cylinder 131.

[0060] (3) Clamping stage: The gas in the air cylinder 131 pushes the piston 132 to extend, and the piston 132 pushes the beveled ring body 121 to move towards the bearing seat 122. The movement of the beveled ring body 121 pushes the long wedge block 123, and the long wedge block 123 moves along the inner bottom surface in the inclined groove and extends outwards, finally pressing against the winding drum installed on the slip ring 1 to achieve clamping and fixing of the winding drum.

[0061] (4) Working stage: The air shaft 2 rotates, driving the fixed sleeve 11 sleeved on it to rotate together. The fixed sleeve 11 drives the piston 132 to rotate, and the frictional force between the piston 132 and the beveled ring body 121 drives the beveled ring body 121, the long wedge block 123, and the winding drum to rotate, thereby realizing winding or unwinding operations. When multiple slip rings work simultaneously, if the rotational speeds of each winding drum are different, the piston 132 and the beveled ring body 121 of some slip rings slip, balancing the rotational speeds of each winding drum and ensuring the stable progress of the winding or unwinding process.

[0062] (5)Adjustment stage (if necessary): When winding diaphragms with different tension magnitudes, rotate the adjustment sleeve 133 of the slip ring 1. The baffle plate 1331 on the adjustment sleeve 133 reaches between different numbers of pistons 132 and the beveled ring body 121, changing the number of pistons 132 participating in the operation to adapt to diaphragms with different tensions. After the adjustment is completed, continue the winding or unwinding operation.

[0063] The present application also provides a method for balancing the tension of the slip ring of a slip shaft, which is applicable to the slip shaft described above and includes the following steps: S1. Respectively install several drums 3 on each slip ring 1, and set a tension detection device on each slip ring 1, and rotate the driving member to drive the air shaft 2 to rotate; S2. Obtain the tension between each slip ring 1 and the drum 3 on the air shaft 2 detected by the tension detection device; S3. If the difference in tension between each slip ring 1 and the drum 3 is greater than a preset threshold value, stop the driving member, and then increase the number of effective pistons 132 of the slip ring 1 with a smaller tension or decrease the number of effective pistons 132 of the slip ring 1 with a larger tension, so that the difference in tension between each slip ring 1 and the drum 3 is less than the preset threshold value.

[0064] In this embodiment, by setting a tension detection device on each slip ring, the tension data between the slip ring and the drum is obtained in real time. When the difference in tension between each slip ring and the drum is greater than the preset threshold value, the number of effective pistons is adjusted in a timely manner to make the difference in tension less than the preset threshold value. This can ensure that the tension received by each drum during the winding process is uniform, avoiding problems such as material deformation, wrinkles, and fractures caused by uneven tension, thereby ensuring the winding quality and improving the product qualification rate. This method can timely detect and solve the problem of uneven tension between slip rings, avoiding additional stress and wear on the entire slip shaft and winding equipment caused by abnormal tension of individual slip rings. By adjusting the number of effective pistons to balance the tension, it helps to maintain the stable operation of the equipment, extend the service life of the equipment, reduce equipment failures and downtime, and improve the reliability and stability of the equipment.

[0065] Such as Figure 12As shown, in a specific embodiment, the first reel 3a is mounted on the first slip ring 1a and the second slip ring 1b, and the second reel 3b is mounted on the third slip ring 1c and the fourth slip ring 1d. Assuming that each slip ring uses 12 pistons, the tension measured by the first slip ring 1a is 50N, the tension measured by the second slip ring 1b is 50N, the tension measured by the third slip ring 1c is 40N, and the tension measured by the fourth slip ring 1d is 35N. Then the total tension of the first reel 3a is 100N, and the total tension of the second reel 3b is 75N. The tension error between the two reels is 25%. To reduce the error, the number of pistons used in the first slip ring 1a is changed to 9, and the number of pistons used in the second slip ring 1b is also changed to 9, so that the tension measured by the first slip ring 1a is 37.5N, and the tension measured by the second slip ring 1b is 37.5N. At this time, the total tension of the first reel 3a is 75N, which is the same as the tension of the second reel 3b, minimizing the tension error between the two reels and being more beneficial to the quality of the wound material.

[0066] The technical effects of the technical solution provided by this application include: (1) Compared with the traditional way of replacing the whole slip ring when winding diaphragms with different tensions, this technical solution can adjust the number of pistons 132 participating in the work by rotating the adjusting sleeve 133, greatly simplifying the operation process, improving the work efficiency, and reducing the time loss caused by replacing the slip ring. It avoids the purchase cost caused by frequent overall replacement of the slip ring, reduces the investment of the enterprise in the components of the winding equipment, effectively saves the production and operation cost of the enterprise, and improves the economic benefit of the enterprise. At the same time, it can flexibly adjust the number of pistons 123 used to adapt to diaphragms with different tension sizes, making the slip ring applicable to various winding operations with different tension requirements, expanding its application range, and enhancing the versatility and flexibility of the equipment.

[0067] (2) The setting of the positioning elastic member 1351 and the positioning glass bead 1352 ensures that the adjusting sleeve 133 can stably maintain its position after adjustment, preventing the adjusting sleeve from rotating due to vibration, external force and other factors during the operation of the slip ring and changing the number of pistons in work, ensuring the stability of the working state of the slip ring, and then ensuring the stability and reliability of the winding or unwinding operation, and avoiding the winding quality problems caused by the unstable number of pistons in work.

[0068] (3)When the positioning glass bead 1352 enters different positioning holes 1333, the adjusting sleeve 133 rotates to different positions. At this time, different numerical markings 113 on the outer side wall of the fixed sleeve 11 will reach the position of the observation hole 1334 on the outer side wall of the adjusting sleeve 133. The operator can directly see the corresponding numerical markings through the observation hole, so as to intuitively understand the current position of the adjusting sleeve and the number of pistons participating in the work at this time (because different positions of the adjusting sleeve correspond to different numbers of pistons participating in the work). This intuitive display method enables the operator to quickly and accurately obtain the adjustment state of the slip ring without complex operations or additional detection equipment, improving the convenience and efficiency of the operation.

[0069] (4)By setting a tension detection device on each slip ring, the tension data between the slip ring and the reel can be obtained in real time. When the tension difference between each slip ring and the reel is greater than the preset threshold, the number of effective pistons is adjusted in a timely manner to make the tension difference less than the preset threshold. This can ensure that the tension received by each reel during the winding process is uniform, avoiding problems such as material deformation, wrinkles, and fractures caused by uneven tension, thereby ensuring the winding quality and improving the product qualification rate. This method can timely detect and solve the problem of uneven tension between slip rings, avoiding additional stress and wear on the entire slip shaft and winding equipment caused by abnormal tension of individual slip rings. By adjusting the number of effective pistons to balance the tension, it helps to maintain the stable operation of the equipment, extend the service life of the equipment, reduce equipment failures and downtime, and improve the reliability and stability of the equipment.

Any other corresponding changes and deformations made according to the technical concept of the present application should be included in the protection scope of the present application.
