Description

Technical Field

[0001] This invention relates to the field of steel strand production equipment technology, and more specifically, to a fully automatic quantitative winding and cutting machine for cable steel strands. Background Technology

[0002] The content in this section only provides background information related to this invention and may not constitute prior art.

[0003] As a core load-bearing component of overhead transmission lines, cable steel strands are widely used in engineering fields such as high-voltage power transmission and electrified railway contact networks. In the construction and production process, the coiled cable steel strands need to be wound into coils according to a set number of turns and a set length, and then tied with binding tape to facilitate subsequent transportation, storage and on-site installation. With the continuous expansion of the power grid construction scale, higher requirements are placed on the automation level and production efficiency of the quantitative winding and cutting of cable steel strands.

[0004] The existing fully automatic cable strand quantitative winding and cutting machine typically operates as follows: the coiled cable strand is conveyed to the cutting machine after being pulled and straightened by four active rollers. After being driven and straightened by the four rollers, the strand enters the disc winding mechanism. The disc is equipped with a tensioning structure, and the diameter change operation is achieved by a cylinder drive, winding the strand onto the disc. Then, the disc is driven to rotate. When the strand is wound to the set length, the cutting machine performs the cutting action, completing the quantitative winding and cutting.

[0005] However, the aforementioned technologies have the following drawbacks: the tensioning structure on the disc achieves diameter change by driving the arc block to move radially through a cylinder. However, during the winding of the steel strand, as the number of rotations of the disc increases, the radial pressure generated by the already wound steel strand on the arc block continues to accumulate and increase, while the output torque of the cylinder remains relatively constant. This causes the actual working diameter of the disc to passively shrink in the later stages of winding, and the winding diameter of the steel strand gradually deviates from the set value. The uneven distribution of tension between each turn will directly affect the dimensional accuracy of the winding and the quality of the coil. Summary of the Invention

[0006] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a fully automatic cable steel strand quantitative winding and cutting machine, which can improve the dimensional accuracy and coiling quality of steel strand quantitative winding.

[0014] In some possible embodiments, a first through slot is formed between the first limiting racks for the drive member to pass through, and a second through slot is formed between the second limiting racks for the drive member to pass through.

[0015] In some possible embodiments, the drive unit is configured as a cylinder, the cylinder is equipped with a servo valve, and a one-way throttle valve is configured in the air path between the cylinder and the servo valve. One gas outlet of the one-way throttle valve is connected to the drive air chamber of the cylinder, and the other gas outlet is connected to the return air chamber of the cylinder. Both the servo valve and the one-way throttle valve are connected to the detection component.

[0016] In some possible embodiments, a wire cleaning and cutting mechanism is provided between the feeding mechanism and the stranding reel; the wire cleaning and cutting mechanism includes a mounting box, in which two sets of guide roller assemblies are provided, the two sets of guide roller assemblies are respectively located at both ends of the mounting box, and through holes for steel strands to pass through are opened at both ends of the mounting box; a mounting frame is fixedly provided between the two sets of guide roller assemblies, and a wire cleaner is rotatably mounted on the mounting frame; the wire cleaner has a through hole for steel strands to pass through, and a threaded cleaning plate is provided in the through hole for contacting the steel strands; a rotating component is provided on the mounting box for driving the wire cleaner to rotate.

[0019] In summary, the technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0020] 1. By setting up a detection component to monitor the pressure on the tension block in real time and connecting the detection component to the drive unit, when the pressure fluctuates, the drive unit drives the tension block to move radially along the strand reel through the transmission component. It can dynamically compensate the position of the tension block according to the real-time changes in radial pressure during the winding process, effectively overcoming the defect of passive shrinkage of the working diameter of the arc block under the traditional cylinder constant force output mode, and improving the dimensional accuracy of steel strand winding and the consistency of coiling quality to a certain extent.

[0021] 2. A strip groove is opened on the side wall of the guide rail, and the pressure sensor is set in the inner wall of the strip groove. A pressure block is slidably set in the strip groove, and an abutment block with a first limiting rack is slidably set on the slider. The abutment block and the pressure block are meshed and driven by the second limiting rack on the side wall of the pressure block. The initial abutment position of the abutment block and the pressure block can be adjusted by the driving component, so that the pressure sensor is in the set pre-tightening state when the tension block is not loaded. The initial detection reference of the sensor can be flexibly adjusted according to the specifications and process requirements of the steel strand, which improves the adaptability and detection sensitivity of the detection component to different specifications of steel strand to a certain extent.

[0022] 3. Based on the premise that the drive unit is set as a cylinder and a servo valve is installed on the cylinder, a one-way throttle valve is added to the air line between the cylinder and the servo valve. The one-way throttle valve uses the asymmetric throttling effect of the intake airflow and exhaust airflow to make the intake speed of the cylinder less than the exhaust speed. When the pressure sensor generates a momentary interference signal due to the protrusion of the strands on the surface of the steel strand or mechanical vibration, the cylinder will not produce actual displacement for a short time due to the intake delay. This can effectively mechanically filter the momentary interference signal and avoid the servo valve from frequently malfunctioning due to interference signals, thereby improving the stability and reliability of the equipment operation to a certain extent.

[0023] 4. By setting up a wire cleaning and cutting mechanism between the feeding mechanism and the stranding reel, the steel strand is guided and conveyed by two sets of guide roller assemblies in the mounting box. A wire cleaner with a threaded cleaning plate is set between the two sets of guide roller assemblies. The wire cleaner is driven to rotate by a rotating component, so that the threaded cleaning plate generates relative rotational friction with the surface of the steel strand as the steel strand passes through the through hole. This can effectively remove oxide scale, debris and other foreign objects attached to the surface of the steel strand. To a certain extent, this reduces the physical jamming and signal interference caused by foreign objects entering the winding area with the steel strand and affecting the tensioning block and detection components, thereby reducing the probability of interference signal generation from the source.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] The following is for reference Figures 1 to 9The present invention will be described in further detail below.

[0036] Reference Figure 1 A fully automatic cable steel strand quantitative winding and cutting machine includes a frame 1, on which a feeding mechanism 11 and a stranding reel 12 are provided. Tensioning blocks 13 are evenly arranged along the circumference of the stranding reel 12 and are slidably connected to the stranding reel 12. A driving part 14 is provided on the frame 1 to drive the tensioning blocks 13 to move radially on the stranding reel 12.

[0037] The steel strand is fed to the winding reel 12 by the feeding mechanism 11 for winding. The tensioning block 13 is evenly arranged around the winding reel 12 to provide radial support during the winding process, so that the steel strand can be wound into a circle according to the set circle diameter. The drive unit 14 serves as the active power source and provides driving force for the radial position adjustment of the tensioning block 13, thereby realizing the setting and adjustment of the winding circle diameter.

[0038] Meanwhile, as is common knowledge in this invention, the stranding disc 12 achieves the winding of the steel strand by its own rotation. The power source for the rotation of the stranding disc 12 is not shown in the accompanying drawings, but as is common knowledge, those skilled in the art can set such as a motor as the power source to drive the stranding disc 12 to rotate according to the actual situation.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A transmission assembly 2 is connected between the tension block 13 and the drive unit 14. A detection assembly 15 is provided on the transmission assembly 2. The detection assembly 15 is used to detect the pressure on the tension block 13. The detection assembly 15 is electrically connected to the drive unit 14. When the detection assembly 15 detects a fluctuation in the pressure on the tension block 13, the drive unit 14 drives the tension block 13 to move on the stranded coil 12 through the transmission assembly 2.

[0040] The transmission assembly 2 transmits the power of the drive unit 14 to the tension block 13, enabling the tension block 13 to slide radially along the strand reel 12. The detection assembly 15 monitors the pressure on the tension block 13 in real time and converts the pressure signal into an electrical signal, which is then transmitted to the drive unit 14. When the radial pressure increases due to the increase in the number of turns during the winding of the steel strand, the detection assembly 15 detects the increase in pressure, and the drive unit 14 responds immediately by driving the tension block 13 to move outward through the transmission assembly 2, increasing the winding diameter to compensate for the pressure change, thereby maintaining the set coil diameter.

[0041] Reference Figure 1 , Figure 2 and Figure 3In one embodiment of the present invention, the transmission assembly 2 includes a transmission rod 21, a guide rail 22, and a slider 23. The guide rail 22 is fixedly disposed on the stranded coil 12 along the radial direction of the stranded coil 12. The slider 23 is slidably disposed on the guide rail 22 along the length direction of the guide rail 22. The transmission rod 21 is fixedly connected to the slider 23. One end of the transmission rod 21 is fixedly connected to the tensioning block 13, and the other end is connected to the output end of the drive unit 14. The detection assembly 15 is disposed on the guide rail 22.

[0042] The transmission component 2 adopts a sliding engagement of guide rail 22 and slider 23. Guide rail 22 is fixed on strand 12 and extends radially. When slider 23 slides on guide rail 22, it drives tension block 13 to move synchronously through transmission rod 21. Guide rail 22 constrains the sliding direction of slider 23, so that tension block 13 always maintains the radial direction of strand 12 during movement, avoiding tension block 13 from deflecting or jamming during movement. Transmission rod 21 connects tension block 13 and output end of drive unit 14, transmitting power from drive unit 14 to tension block 13.

[0043] like Figure 3 and Figure 4 As shown, a strip groove 3 is formed on the side wall of the guide rail 22 along the length direction of the guide rail 22. The detection component 15 is set as a pressure sensor. The detection component 15 is set on the inner wall of the strip groove 3 away from the tension block 13. A pressure block 31 is slidably arranged in the strip groove 3 along the length direction of the strip groove 3. One end of the pressure block 31 abuts against the pressure sensor. An abutting block 32 is slidably arranged on the slider 23. One end of the abutting block 32 extends into the strip groove 3. A first limiting rack 33 is fixedly arranged on the side wall of the abutting block 32. A second limiting rack 34 is fixedly arranged on the side wall of the pressure block 31. The first limiting rack 33 and the second limiting rack 34 mesh. A driving member 35 is provided on the slider 23. The driving member 35 is used to drive the abutting block 32 to move closer to or away from the pressure block 31.

[0044] The strip groove 3 is formed on the side wall of the guide rail 22 to provide installation space for the pressure sensor and the pressure block 31. The pressure block 31 is set in the strip groove 3 and can slide along the length of the strip groove 3. One end of the pressure block 31 abuts against the pressure sensor, and the side is connected to the abutment block 32 through the meshing of the first limiting rack 33 and the second limiting rack 34. The abutment block 32 is slidably set on the slider 23 and one end extends into the strip groove 3. As the radial pressure of the steel strand increases due to winding, the pressure is transmitted to the abutment block 32 through the tension block 13. The abutment block 32 transmits the pressure to the second limiting rack 34 through the interlocking first limiting rack 33, and then the pressure is transmitted to the pressure sensor through the pressure block 31.

[0045] In actual use, when the driving component 35 drives the abutment block 32 to approach the pressure block 31 and makes the first limiting rack 33 and the second limiting rack 34 mesh with each other, the relative position between the slider 23 and the guide rail 22 is locked. This state is the state for winding the steel strand. Before winding the steel strand, the position of the tension block 13 on the strand reel 12 needs to be adjusted according to the number of turns to be wound. At this time, the driving component 35 drives the abutment block 32 away from the pressure block 31, so that the first limiting rack 33 and the second limiting rack 34 disengage. At this time, the relative position between the slider 23 and the guide rail 22 is in an adjustable state, and the position of the tension block 13 on the strand reel 12 can be adjusted.

[0046] During the winding of the steel strand, the real-time pressure on the tension block 13 is transmitted to the pressure block 31 through the slider 23, and the pressure signal is detected in real time by the pressure sensor, thereby realizing the real-time detection of the radial pressure on the tension block 13. The rack and pinion meshing has the characteristics of accurate transmission ratio and no slippage, which can ensure the accuracy of pressure transmission. At the same time, the setting of the drive component 35 makes the initial reference adjustable. The same set of detection components 15 can be used for steel strands of different diameters and different winding numbers of steel strands. In actual production, specification switching can be completed without changing the detection element.

[0047] Reference Figure 4 , Figure 5 and Figure 6 The inner wall of the strip groove 3 is provided with an installation hole 36, and an anti-detachment groove 37 is provided in the installation hole 36. The diameter of the anti-detachment groove 37 is larger than that of the installation hole 36. The driving component 35 is configured as a driving rod, which is rotatably inserted into the installation hole 36. An anti-detachment part 38 is rotatably provided in the anti-detachment groove 37. The anti-detachment part 38 is fixedly installed at the end of the driving rod. The abutment block 32 is provided with a through threaded hole 39, and the driving rod is provided with an external thread that is threadedly connected to the threaded hole 39.

[0048] When the operator rotates the drive rod, the axial position of the drive rod is restricted by the anti-disengagement part 38, and the abutment block 32, which is threadedly connected to the drive rod, generates a relative displacement along the axial direction of the drive rod, thereby driving the abutment block 32 to slide on the slider 23, so as to achieve precise adjustment of the position of the abutment block 32 on the slider 23.

[0049] like Figure 6 As shown, a clamping sleeve 4 is slidably sleeved on the drive rod, and an elastic element 41 is provided on the drive rod. The elastic element 41 is used to drive the clamping sleeve 4 to move toward the abutting block 32, and one end face of the clamping sleeve 4 abuts against the abutting block 32.

[0050] Reference Figure 6A limiting groove 42 is formed on the drive rod along its length direction. A limiting block 43 is slidably disposed in the limiting groove 42. A limiting rod 44 is fixedly disposed in the limiting groove 42 along its length direction. The limiting block 43 is slidably disposed in the limiting groove 42 and is fixedly connected to the inner wall of the clamping sleeve 4. The limiting block 43 is sleeved on the limiting rod 44. As one embodiment of the present invention, see [reference needed]. Figure 6 The elastic element 41 is configured as a compression spring. The elastic element 41 is sleeved on the limiting rod 44. One end of the elastic element 41 is fixedly connected to the limiting block 43, and the other end is fixedly connected to the inner wall of the limiting groove 42.

[0051] The clamping sleeve 4 is fitted onto the drive rod and can slide along the drive rod axially. The elastic element 41 applies a spring force to the clamping sleeve 4 in the direction of the abutment block 32, so that the end face of the clamping sleeve 4 always abuts against the abutment block 32. The clamping sleeve 4 can eliminate the thread gap in the threaded connection between the abutment block 32 and the drive rod. During the process of the drive rod rotating to adjust the position of the abutment block 32, the threaded connection inevitably has axial gap. This gap may cause the mechanical vibration generated by the threaded connection during the rotation of the stranded coil 12 to cause the drive rod to deflect, which in turn causes the meshing between the first limiting rack 33 and the second limiting rack 34 to loosen, affecting the detection accuracy of the detection component 15 for pressure. By using the clamping sleeve 4 in conjunction with the elastic element 41, the friction of the threaded surface of the threaded connection can be effectively improved, producing a better self-locking effect, and to a certain extent avoiding the deflection of the drive component 35 due to mechanical vibration.

[0052] As one embodiment of the present invention, refer to Figure 4 A first through groove 51 for the drive member 35 to pass through is provided between the first limiting racks 33, and a second through groove 52 for the drive member 35 to pass through is provided between the second limiting racks 34. The first through groove 51 is provided between the first limiting racks 33, and the second through groove 52 is provided between the second limiting racks 34. The positions of the first through groove 51 and the second through groove 52 correspond to each other and together form a channel for the drive rod to pass through. When the drive rod moves along its own axis to adjust the position of the abutment block 32, the drive rod needs to pass through the area where the first limiting rack 33 and the second limiting rack 34 are located.

[0053] The first through slot 51 and the second through slot 52 provide clearance for the drive rod, so that the drive rod will not interfere with the first limiting rack 33 or the second limiting rack 34 when passing through the meshing rack area. This ensures that the drive rod can rotate freely and move axially, while not affecting the normal meshing transmission between the first limiting rack 33 and the second limiting rack 34.

[0054] like Figure 1 and Figure 9As shown, the drive unit 14 is configured as a cylinder, and a servo valve 61 is provided on the cylinder. A one-way throttle valve 62 is provided in the air path between the cylinder and the servo valve 61. One gas outlet of the one-way throttle valve 62 is connected to the drive air chamber of the cylinder, and the other gas outlet is connected to the return air chamber of the cylinder. Both the servo valve 61 and the one-way throttle valve 62 are connected to the detection component 15.

[0055] The drive unit 14 uses a cylinder as the actuator and a servo valve 61 as the control element. The pressure signal output by the detection component 15 is transmitted to the servo valve 61. The servo valve 61 adjusts the gas flow and pressure entering the cylinder drive chamber according to the signal, thereby controlling the thrust and direction of movement at the cylinder output end.

[0056] A one-way throttle valve 62 is installed in the air path between the cylinder and the servo valve 61. This one-way throttle valve 62 has an asymmetrical throttling effect on the intake airflow entering the cylinder drive chamber and the exhaust airflow exiting the cylinder drive chamber. The flow rate of the intake airflow is less than that of the exhaust airflow, that is, the extension speed of the cylinder piston is slower than the retraction speed. When the pressure sensor generates a momentary interference signal due to the protrusion of the strands on the surface of the steel strand or the mechanical vibration of the equipment, although the servo valve 61 has received the adjustment command and started to act, due to the intake delay effect of the one-way throttle valve 62, the pressure build-up speed in the cylinder drive chamber is slow, which is insufficient to push the cylinder piston to produce actual displacement in a short time. When the interference signal disappears, the adjustment command is cancelled, but the cylinder has not yet actually acted. This delay filtering effect can effectively filter short-duration interference signals and avoid the cylinder from frequently acting due to momentary interference. At the same time, the rapid throttling characteristic of the exhaust air path allows the cylinder to quickly discharge the gas in the drive chamber when it needs to be quickly reset, ensuring the timeliness of the reset action.

[0057] By adjusting the adjusting knob on the one-way throttle valve 62, the size of the throttle orifice can be changed, thereby adjusting the length of the air intake delay. In actual use, the operator sets an appropriate delay time by rotating the adjusting knob according to the winding speed of the steel strand and the operating conditions of the equipment. This ensures that the delay time matches the period of the strand protrusions on the surface of the steel strand and the frequency of mechanical vibration, effectively filtering interference signals without affecting the response speed of normal pressure change signals.

[0058] Reference Figure 7 and Figure 8 A wire clearing and cutting mechanism 7 is provided between the feeding mechanism 11 and the stranding disc 12.

[0059] As shown in the figure, the wire cleaning and cutting mechanism 7 includes a mounting box 71. Two sets of guide roller assemblies 72 are installed inside the mounting box 71. The two sets of guide roller assemblies 72 are respectively located at both ends of the mounting box 71. Both ends of the mounting box 71 have through holes 73 for steel strands to pass through. A mounting frame 74 is fixedly installed between the two sets of guide roller assemblies 72. A wire cleaner 75 is rotatably installed on the mounting frame 74. The wire cleaner 75 has a through hole 76 for steel strands to pass through. A threaded cleaning plate 77 is installed inside the through hole 76 for contacting the steel strands. A rotating component 78 is installed on the mounting box 71 to drive the wire cleaner 75 to rotate.

[0060] The mounting box 71 has through holes 73 at both ends. The steel strand enters the mounting box 71 through one through hole 73 and exits through the other through hole 73. Two sets of guide roller assemblies 72 are respectively set at both ends of the mounting box 71 to guide and support the steel strand entering and exiting the mounting box 71, ensuring that the conveying path of the steel strand in the mounting box 71 remains straight. The mounting frame 74 is fixedly set between the two sets of guide roller assemblies 72. The wire cleaner 75 is rotatably set on the mounting frame 74 and located on the conveying path of the steel strand. The steel strand passes through the through hole 76 opened on the wire cleaner 75. The threaded cleaning plate 77 set in the through hole 76 contacts the surface of the steel strand. The rotating part 78 drives the wire cleaner 75 to rotate around the axis of the steel strand. When the wire cleaner 75 rotates, the threaded cleaning plate 77 generates relative rotational friction with the surface of the steel strand, peeling off the oxide scale, debris and other foreign objects attached to the surface of the steel strand.

[0061] As one embodiment of the present invention, refer to Figure 8 There are three thread cleaning plates 77, which are evenly arranged in the through hole 76 along the circumference of the through hole 76.

[0062] Before the steel strand enters the stranding reel 12, foreign objects attached to its surface are effectively removed, reducing the possibility that foreign objects will get stuck between the tension block 13 and the sliding mating surface of the stranding reel 12 after entering the winding area with the steel strand. This reduces problems such as increased sliding resistance and poor movement of the tension block 13 caused by foreign object jamming. At the same time, removing foreign objects from the surface of the steel strand also reduces the physical contact interference of foreign objects on the detection component 15 to a certain extent, which is conducive to the pressure sensor obtaining a relatively stable pressure signal.

[0063] Reference Figure 7 and Figure 8The mounting bracket 74 is rotatably provided with a receiving part 8, which has a through receiving hole 81. The wire cleaner 75 is disposed in the receiving hole 81 and is detachably connected to the receiving part 8. A first bevel gear 82 is coaxially fixedly disposed on the receiving part 8. The rotating part 78 is a rotating motor, which is fixedly disposed on the mounting box 71. A second bevel gear 83 is disposed on the output shaft of the rotating motor. The first bevel gear 82 and the second bevel gear 83 mesh with each other.

[0064] like Figure 8 As shown, the receiving part 8 has a slot 85, and a plug 84 is provided in the slot 85. The plug 84 is fixedly connected to the outer peripheral wall of the cleaner 75, and the plug 84 and the slot 85 are detachably connected by a connecting bolt 86.

[0065] When the thread cleaning plate 77 wears out after the wire cleaner 75 has been used for a period of time, the connecting bolt 86 can be loosened to remove the wire cleaner 75 from the housing 8 for replacement or repair. The detachable connection structure allows the wire cleaner 75 to be replaced periodically as an independent consumable, which facilitates the daily maintenance and upkeep of the equipment in actual production and reduces maintenance costs.

[0066] During the actual operation of the wire cleaning and cutting mechanism 7, the rotation speed of the rotating motor can be adjusted according to the conveying speed of the steel strand. When the steel strand is conveyed at a relatively fast speed, the rotation speed of the rotating motor can be appropriately increased to keep the relative rotation speed between the thread cleaning plate 77 and the surface of the steel strand within a certain range to ensure the cleaning effect. When the steel strand is conveyed at a relatively slow speed, the rotation speed of the rotating motor can be appropriately reduced to reduce energy consumption and reduce the wear of the thread cleaning plate 77.

[0067] The implementation principle of the fully automatic quantitative cable strand cutting machine proposed in this embodiment of the invention is as follows:

[0068] The steel strand is conveyed by the feeding mechanism 11 and first passes through the cleaning and cutting mechanism 7 for surface cleaning. The steel strand enters through the through hole 73 at one end of the mounting box 71, is guided by the guide roller assembly 72, and then passes through the through hole 76 of the cleaner 75. The threaded cleaning plate 77 in the through hole 76 contacts the surface of the steel strand. The rotating motor drives the receiving part 8 and the cleaner 75 to rotate through the meshing of the first bevel gear 82 and the second bevel gear 83. The threaded cleaning plate 77 rotates with the cleaner 75 and generates relative friction with the surface of the steel strand, peeling off and removing the oxide scale, debris and other foreign matter attached to the surface of the steel strand. After cleaning, the steel strand is guided by the guide roller assembly 72 at the other end and passes out through the through hole 73, and enters the stranding reel 12 for winding.

[0069] After the steel strand enters the stranding reel 12, it is wound around the outside of the tensioning block 13 arranged around the circumference of the stranding reel 12. The rotation of the stranding reel 12 drives the steel strand to wind around one turn at a time. As the number of turns increases, the wound steel strand generates radial pressure on the tensioning block 13. This radial pressure is transmitted to the transmission rod 21 through the tensioning block 13. The transmission rod 21 transmits the pressure to the slider 23. The slider 23 transmits the pressure to the second limit rack 34 through the first limit rack 33 on the abutment block 32, and finally to the pressure block 31. The pressure block 31 acts on the pressure sensor. The pressure sensor converts the detected pressure signal into an electrical signal and transmits it to the servo valve 61 and the one-way throttle valve 62.

[0070] The servo valve 61 controls the gas flow rate into the cylinder drive chamber according to the received pressure signal. When the pressure sensor detects that the pressure on the tension block 13 continues to increase, it indicates that the number of strand winding layers has increased, resulting in radial pressure accumulation. The servo valve 61 increases the gas flow rate into the cylinder drive chamber, pushes the cylinder output end to extend, and drives the tension block 13 to move radially outward along the strand reel 12 through the transmission rod 21, increasing the winding diameter to compensate for the effect of pressure accumulation.

[0071] During the control process described above, the one-way throttle valve 62 applies a delay effect to the gas entering the cylinder drive chamber. When the pressure sensor outputs an instantaneous spike signal, such as that caused by the protrusion of the strands on the surface of the steel strand or mechanical vibration, and the duration of this signal is shorter than the delay time set by the one-way throttle valve 62, the pressure in the cylinder drive chamber has not yet been built up to a level sufficient to push the piston to move. The interference signal has already disappeared, and the servo valve 61 then cancels the adjustment command. The cylinder does not produce any actual displacement. When the pressure change signal output by the pressure sensor is a continuous signal and the duration exceeds the delay time, it indicates that the pressure signal is generated by the accumulation of the number of turns of the steel strand. At this time, the pressure in the cylinder drive chamber is gradually built up and pushes the piston to move, thereby realizing the dynamic adjustment of the position of the tension block 13.

[0072] Through the above structure, the device as a whole can dynamically adjust the radial position of the tensioning block 13 according to the actual radial pressure changes during the winding process of the steel strand, maintain the stability of the working diameter of the strand reel 12, and thus achieve consistent control of the dimensional accuracy of the steel strand winding and the quality of the coiling.

[0073] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
