Description

Technical Field

[0001] This invention belongs to the field of yarn winding technology, specifically referring to a winding device for the production of water-blocking yarn. Background Technology

[0002] Normally, to prevent cables and optical fibers from leaking due to accidental damage in humid and watery environments, water-blocking materials, such as water-blocking yarn and water-blocking rope, are pre-wrapped in the interlayer of cables and optical fibers. The principle is that they expand rapidly when they come into contact with water, thereby filling the gaps around them and achieving the effect of blocking and preventing water.

[0003] Based on the characteristics of the raw materials and products of water-blocking yarn, it cannot withstand large tensile forces. In production, it should also follow the principle of "gentle opening and combing, short process, and minimal shedding". Therefore, when winding and coiling, the tension requirements of water-blocking yarn during coiling are relatively strict (the usable tension range is small). If the tension is too high, it is easy to break. Even if it does not break, it is easy to cause the winding to be too tight (this is different from ordinary yarn). If the tension is too low, it is easy to cause the wound material to be too loose and not formed.

[0004] Therefore, there is a need in the market for a winding device for the production of water-resistant yarn that can adjust and maintain tension. Summary of the Invention

[0005] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a winding device for the production of water-resistant yarn. Compared to a device directly connected to a drive mechanism, the intermediate spring connection not only quantifies and provides feedback on the tension force through the deformation of the spring, but also minimizes tension fluctuations caused by displacement of the tension wheel. Furthermore, during yarn winding, the traditional winding method of one end actively pulling and the other end passively cannot be used (as this would result in excessive tension and breakage). Instead, a winding method with both ends actively engaged (one end releasing and the other winding) is required. During this process, the yarn tension is prone to fluctuation due to factors such as the increasing size of the winding roller and fluctuations in the production speed at the feeding end. Therefore, this invention also needs to possess the technical function of automatically compensating for and adjusting the tension force.

[0006] Based on the analysis of the motion states of the tension adjustment mechanism and the offset feedback mechanism, it can be seen that the adjustment range D of the nut seat is equal to the displacement d of the tension fork plus the offset x of the position indicator. Since the yarn itself has almost no elasticity, we can assume that the positions of the tension fork and the tension wheel are almost fixed before and after adjustment. Therefore, we can conclude that "the adjustment range D is equal to the offset value x of the position indicator," that is:

[0007]

[0008] To completely eliminate the error caused by such approximate calculation, this invention proposes a loop-overlapping control logic. Each loop performs a new measurement on x, so that the error of each time is covered by the new measurement, and no error accumulation occurs (because each control is based on the current measurement, not the previous measurement), thereby greatly improving the accuracy of tension control.

[0009] The technical solution adopted by the present invention is as follows: The present invention proposes a winding device for the production of water-blocking yarn, including a main frame mechanism and a transverse roller assembly, wherein the transverse roller assembly is disposed on the main frame mechanism, and further includes a tension adjustment mechanism and an offset feedback mechanism, wherein the tension adjustment mechanism is disposed in the transverse roller assembly, and the offset feedback mechanism is disposed on the tension adjustment mechanism.

[0010] Through the automatic adjustment of the tension adjustment mechanism, the deformation amplitude of the tension spring can always be maintained within a stable range, thereby adaptively compensating for and adjusting the tension borne by the yarn body, and thus achieving the technical goal of maintaining constant tension even when there are fluctuations in the instantaneous release and winding speed.

[0011] Furthermore, the tension adjustment mechanism includes an adjustment drive assembly, a transmission assembly, and a tension generating assembly. The adjustment drive assembly is disposed in the transverse roller assembly, the transmission assembly is disposed on the tension generating assembly, and the tension generating assembly is disposed on the adjustment drive assembly. The adjustment drive assembly includes a motor bracket, an adjustment motor, and a coupling. The motor bracket is fixed to the transverse roller assembly, the adjustment motor is disposed on the motor bracket, and the coupling is engaged with the output shaft of the adjustment motor.

[0012] Preferably, the transmission assembly includes a nut seat, a transmission nut, and a transmission stud. The nut seat is disposed on the tension generating assembly, and guide sliding holes are symmetrically provided at both ends of the nut seat. The transmission nut is engaged at the center position of the nut seat. The transmission stud is disposed in a coupling, and the transmission stud is connected to the output shaft of the regulating motor through the coupling. The transmission nut and the transmission stud are threadedly connected.

[0013] As a further preferred embodiment of the present invention, the tension generating assembly includes a tension fork, a tension wheel, and a tension spring. The tension fork is symmetrically provided with guide posts, and the tension fork is slidably engaged with and slidably disposed in a guide sleeve via the guide posts. The nut seat is slidably engaged with and slidably disposed on the guide posts via guide holes. The tension fork is symmetrically provided with fork support portions. The tension wheel is provided with a tensioning spindle, and the tension wheel is rotatably disposed in the fork support portions via the tensioning spindle. The tension spring is disposed between the tension fork and the nut seat.

[0014] When the tension changes, it means that the deformation amplitude of the tension spring also changes. At this time, by compensating and adjusting the nut seat, the tension amplitude of the tension spring can be restored to the preset position. The relative distance between the nut seat and the tension fork can intuitively reflect the tension magnitude under the current state.

[0015] Furthermore, the offset feedback mechanism includes a fixing component and an adjusting feedback component. The fixing component is disposed on the guide post, and the adjusting feedback component is disposed on the fixing component. The fixing component includes a feedback shaft support frame and a feedback shaft. The feedback shaft support frame is engaged at both ends of the guide post, and the feedback shaft is disposed between the feedback shaft support frame. A threaded adjusting part is provided at the middle position of the feedback shaft.

[0016] Preferably, the adjustment feedback component includes a threaded adjustment seat and a position indicator. The threaded adjustment seat and the threaded adjustment part are threadedly connected. One end of the threaded adjustment seat is provided with an adjustment handwheel. The outer surface of the threaded adjustment seat is provided with a position sensing area. One end of the position indicator is fixed to the nut seat, and the other end of the position indicator is in sliding contact with the position sensing area.

[0017] By observing the relative position of the position indicator and the position sensing area, the direction and magnitude of the change in the tension spring tension can be determined. The positional offset between the position indicator and the position sensing area can be measured using both analog and digital methods. Each method corresponds to different hardware, software, and control logic, but the technical objective is the same, and the appropriate method can be selected based on different needs and operating conditions.

[0018] Furthermore, the main frame mechanism includes a main frame and an idler wheel body. The idler wheel body is provided with an idler wheel mounting hole and an idler wheel spindle. The idler wheel body is rotatably mounted in the idler wheel mounting hole via the idler wheel spindle.

[0019] Furthermore, the transverse roller assembly includes a transverse module, a support assembly, and a winding assembly. The transverse module is mounted on the main frame. The support assembly includes a transverse support, a detachable end cap, and a support bearing. The transverse support is mounted on the sliding part of the transverse module. The detachable end cap is detachably mounted on one end of the transverse support. The support bearing is engaged in the detachable end cap. If the bottom is for directly winding the yarn produced in the previous process, only one set of transverse roller assemblies is needed at the top. If the bottom is for secondary winding of the pre-wound yarn to precisely adjust the tension, spacing, and arrangement, then two sets of transverse roller assemblies are needed at the bottom and top respectively.

[0020] Preferably, the winding assembly includes a winding motor, a winding roller, and a yarn body. The winding motor is mounted on a transverse support, one end of the winding roller is engaged with the output shaft of the winding motor, and the other end of the winding roller is engaged with a support bearing. The yarn body is wound on the winding roller.

[0021] As a further preferred embodiment of the present invention, the position sensing area is a sliding switch base, and the position indicator is a sliding switch contact. The rotation direction and power of the motor can be controlled according to the direction and amplitude of the contact relative to the base. When the contact of the sliding switch is located within the middle range, the motor is stationary.

[0022] As a further preferred embodiment of the present invention, the position sensing area is an encoder scale, the position indicator is an encoder reading head, and after the program starts, it enters a loop, in which the following steps are repeatedly executed:

[0023] Step 1: Read the position parameter of the reading head and assign the value to S; read the current state of the switch and assign it to K.

[0024] Step 2: Determine the current program on / off state based on the value of K, and decide whether to exit the entire program;

[0025] Step 3: Compare S with the preset critical value U. If S≤-U, the motor rotates forward to increase the pulling force. If S≥U, the motor rotates in reverse to decrease the pulling force. If -U≤S≤U, exit the current loop.

[0026] The analog control method has a simple structure and control logic, using a simple mechanical slide switch to control the rotation direction and power of the motor, thus achieving fully mechanical negative feedback control. The digital control method uses a high-precision encoder as the measurement unit, quantizes the measurement results and imports them into the control program. Although it is more expensive and has a more complex structure, it has relatively higher accuracy and sensitivity. These two control methods are suitable for different yarn materials and working conditions, and users can choose the one that best suits them.

[0027] The beneficial effects achieved by the present invention using the above structure are as follows:

[0028] (1) Through the automatic adjustment of the tension adjustment mechanism, the deformation amplitude of the tension spring can always be maintained within a stable range, thereby adaptively compensating and adjusting the tension borne by the yarn body, and thus achieving the technical objective of maintaining constant tension even when there are fluctuations in the instant release and winding speed.

[0029] (2) When the tension changes, it means that the deformation amplitude of the tension spring also changes. At this time, by compensating and adjusting the nut seat, the tension amplitude of the tension spring can be restored to the preset position. The relative distance between the nut seat and the tension fork can intuitively reflect the tension in the current state.

[0030] (3) By the relative position of the position indicator and the position sensing area, the direction and magnitude of the change in the tension spring tension can be known. The position offset between the position indicator and the position sensing area can be ranged by analog and digital means. Each means corresponds to different hardware and software and control logic, but the technical goal is the same. It can be selected according to different needs and working conditions.

[0031] (4) If the bottom is directly wound up the yarn produced in the previous process, then only one set of transverse roller assembly is needed at the top. If the bottom is used to rewind the yarn that has been initially wound up to accurately adjust the tension, spacing and arrangement, then two sets of transverse roller assembly are needed at the bottom and top respectively.

[0032] (5) The analog quantity adjustment method has a simple structure and control logic. It uses a simple mechanical sliding switch to control the rotation direction and power of the motor, thereby realizing a fully mechanical negative feedback adjustment. The digital quantity adjustment method uses a high-precision encoder as the measurement unit, quantifies the measurement results and imports them into the control program. Although it is costly and complex in structure, it has relatively high accuracy and sensitivity. These two adjustment methods are suitable for different yarn materials and working conditions, and users can choose for themselves. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0051] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0052] like Figures 1-13 As shown, the present invention proposes a winding device for the production of water-blocking yarn, including a main frame mechanism 3 and a transverse roller assembly 4, the transverse roller assembly 4 being disposed on the main frame mechanism 3, and further including a tension adjustment mechanism 1 and an offset feedback mechanism 2, the tension adjustment mechanism 1 being disposed in the transverse roller assembly 4, and the offset feedback mechanism 2 being disposed on the tension adjustment mechanism 1.

[0053] Through the automatic adjustment of the tension adjustment mechanism 1, the deformation amplitude of the tension spring 16 can always be maintained within a stable range, thereby adaptively compensating for and adjusting the tension borne by the yarn body 43, and thus achieving the technical objective of maintaining constant tension even when there are fluctuations in the release and winding speed.

[0054] The tension adjustment mechanism 1 includes an adjustment drive assembly 5, a transmission assembly 6, and a tension generating assembly 7. The adjustment drive assembly 5 is located in the transverse roller assembly 4, the transmission assembly 6 is located on the tension generating assembly 7, and the tension generating assembly 7 is located on the adjustment drive assembly 5. The adjustment drive assembly 5 includes a motor bracket 8, an adjustment motor 9, and a coupling 10. The motor bracket 8 is fixed to the transverse roller assembly 4, the adjustment motor 9 is located on the motor bracket 8, and the coupling 10 is engaged with the output shaft of the adjustment motor 9.

[0055] The transmission assembly 6 includes a nut seat 11, a transmission nut 12, and a transmission stud 13. The nut seat 11 is mounted on the tension generating assembly 7. Guide sliding holes 18 are symmetrically provided at both ends of the nut seat 11. The transmission nut 12 is engaged at the center of the nut seat 11. The transmission stud 13 is located in the coupling 10. The transmission stud 13 and the output shaft of the regulating motor 9 are connected by the coupling 10. The transmission nut 12 and the transmission stud 13 are threadedly connected.

[0056] The tension generating assembly 7 includes a tension fork 14, a tension wheel 15, and a tension spring 16. The tension fork 14 is symmetrically provided with guide posts 19. The tension fork 14 is engaged and slidably disposed in the guide sleeve 17 through the guide posts 19. The nut seat 11 is engaged and slidably disposed on the guide posts 19 through the guide holes 18. The tension fork 14 is symmetrically provided with fork support parts 20. The tension wheel 15 is provided with a tension main shaft 21. The tension wheel 15 is rotatably disposed in the fork support part 20 through the tension main shaft 21. The tension spring 16 is disposed between the tension fork 14 and the nut seat 11.

[0057] When the tension changes, it means that the deformation amplitude of the tension spring 16 also changes. At this time, by compensating and adjusting the nut seat 11, the tension amplitude of the tension spring 16 can be restored to the preset position. The relative distance between the nut seat 11 and the tension fork 14 can intuitively reflect the magnitude of the tension in the current state.

[0058] The offset feedback mechanism 2 includes a fixed component 22 and an adjustable feedback component 23. The fixed component 22 is mounted on the guide post 19, and the adjustable feedback component 23 is mounted on the fixed component 22. The fixed component 22 includes a feedback shaft support frame 24 and a feedback shaft 25. The feedback shaft support frame 24 is engaged at both ends of the guide post 19, and the feedback shaft 25 is located between the feedback shaft support frame 24. A threaded adjustment part 28 is provided at the middle position of the feedback shaft 25.

[0059] The adjustment feedback component 23 includes a threaded adjustment seat 26 and a position indicator 27. The threaded adjustment seat 26 and the threaded adjustment part 28 are threadedly connected. One end of the threaded adjustment seat 26 is provided with an adjustment handwheel 29. The outer surface of the threaded adjustment seat 26 is provided with a position sensing area 30. One end of the position indicator 27 is fixed to the nut seat 11, and the other end of the position indicator 27 slides in contact with the position sensing area 30.

[0060] By observing the relative position of the position indicator 27 and the position sensing area 30, the direction and magnitude of the change in the tension of the tension spring 16 can be determined. The positional offset between the position indicator 27 and the position sensing area 30 can be controlled by analog and digital signals. Each method corresponds to different hardware and software and control logic, but the technical goal is the same. The appropriate method can be selected according to different needs and working conditions.

[0061] The main frame mechanism 3 includes a main frame 31 and an idler wheel body 32. The idler wheel body 32 is provided with an idler wheel mounting hole 33 and an idler wheel spindle 34. The idler wheel body 32 is rotatably mounted in the idler wheel mounting hole 33 through the idler wheel spindle 34.

[0062] The transverse roller assembly 4 includes a transverse module 35, a support assembly 36, and a winding assembly 37. The transverse module 35 is mounted on the main frame 31. The support assembly 36 includes a transverse support 38, a detachable end cap 39, and a support bearing 40. The transverse support 38 is mounted on the sliding part of the transverse module 35. The detachable end cap 39 is detachably mounted on one end of the transverse support 38. The support bearing 40 is engaged in the detachable end cap 39. If the bottom is for directly winding the yarn produced in the previous process, only one set of transverse roller assemblies 4 is needed at the top. If the bottom is for secondary winding of the yarn that has already been initially wound to precisely adjust the tension, spacing, and arrangement, then two sets of transverse roller assemblies 4 are needed at the bottom and top respectively.

[0063] The winding assembly 37 includes a winding motor 41, a winding roller 42, and a yarn body 43. The winding motor 41 is mounted on a transverse support 38. One end of the winding roller 42 is engaged with the output shaft of the winding motor 41, and the other end of the winding roller 42 is engaged with the support bearing 40. The yarn body 43 is wound on the winding roller 42.

[0064] like Figure 15 As shown, the position sensing area 30 is the base of the sliding switch, and the position indicator 27 is the contact of the sliding switch. The rotation direction and power of the motor can be controlled according to the direction and amplitude of the contact relative to the base. When the contact of the sliding switch is within the middle range, the motor stops.

[0065] The position sensing area 30 is the encoder scale, and the position indicator 27 is the encoder reading head. After the program starts, it enters a loop, and the following steps are repeatedly executed in the loop:

[0066] Step 1: Read the position parameter of the reading head and assign the value to S; read the current state of the switch and assign it to K.

[0067] Step 2: Determine the current program on / off state based on the value of K, and decide whether to exit the entire program;

[0068] Step 3: Compare S with the preset critical value U: If S≤-U, the motor rotates forward to increase the pulling force; if S≥U, the motor rotates in reverse to decrease the pulling force; if -U≥S≤U, exit the current loop.

[0069] The analog control method has a simple structure and control logic, using a simple mechanical slide switch to control the rotation direction and power of the motor, thus achieving fully mechanical negative feedback control. The digital control method uses a high-precision encoder as the measurement unit, quantizes the measurement results and imports them into the control program. Although it is more expensive and has a more complex structure, it has relatively higher accuracy and sensitivity. These two control methods are suitable for different yarn materials and working conditions, and users can choose the one that best suits them.

[0070] like Figure 14 As shown, the horizontal axis with scale represents the position sensing area 30, and the vertical rod represents the position indicator 27. When the position indicator 27 is near the 0 mark of the position sensing area 30, the adjusting motor 9 does not rotate. When the position indicator 27 is in the positive range, the position indicator 27 can be moved to the 0 mark by adjusting the rotation of the adjusting motor 9. When the position indicator 27 is in the negative range, the position indicator 27 can also be moved to the 0 mark by adjusting the rotation of the adjusting motor 9.

[0071] In practical use, the user first needs to pass the yarn body 43 around the tension wheel 15 and the idler wheel body 32 and wind it onto the winding roller 42. During the winding process of the yarn body 43, the reciprocating slow movement of the transverse module 35 can control the transverse movement of the winding roller 42, change the corresponding position of the winding roller 42 and the tension wheel 15, thereby ensuring that the yarn can be wound from one end of the winding roller 42 to the other end during winding.

[0072] During the winding process, if the yarn tension changes, the extension and retraction of the tension spring 16 will also change. At this time, the relative position of the base and contact of the sliding switch changes. When the position indicator 27 moves away from the vicinity of the 0 mark of the position sensing area 30, the rotation direction and power of the motor 9 will be adjusted according to the direction and position of the position indicator 27. If the tension increases, the nut seat 11 will be pushed toward the tension fork 14 to reset the extension of the tension spring 16. If the tension decreases, the nut seat 11 will be pulled away from the tension fork 14 to reset the extension of the tension spring 16. When the contact of the sliding switch is in the middle range, the motor stops.

[0073] In another new embodiment of the present invention, the position sensing area 30 is an encoder scale, the position indicator 27 is an encoder reading head, and after the program starts, it enters a loop, in which the following steps are repeatedly executed:

[0074] Step 1: Preset the functional relationship between the offset x and the motor compensation y: y=f(x); Preset the accuracy range -U~U;

[0075] Step 2: When the program starts, assign the value 1 to K and start the following loop (you can choose a for loop).

[0076] Step 3: Read the position information of the sliding switch and assign the value to parameter S. Read the current state of the switch and assign it to K, with 1 for on and 0 for off.

[0077] Step 4: If K=0, break (exit the loop and end the program).

[0078] Step 5: If S≤-U, the motor rotates forward to increase the pulling force, and the nut offset y=f(s);

[0079] Step 6: If S≥U, the motor reverses to reduce the pulling force, and the nut offset y=f(s);

[0080] Step 7: If -U≤S≤U, continue (exit the current loop and enter a new loop).

[0081] Through the feedback of the offset feedback mechanism 2 and the automatic adjustment of the tension adjustment mechanism 1, the deformation amplitude of the tension spring 16 can always be maintained within a stable range, thereby adaptively compensating for and adjusting the tension borne by the yarn body 43, and thus achieving the technical objective of maintaining constant tension even when there are fluctuations in the release and winding speed.

[0082] In summary, through the above-mentioned negative feedback adjustment, the elongation of the tension spring 16 will eventually be balanced when the position indicator 27 is located near the 0 mark of the position sensing area 30. When it is necessary to change the tension value, it is only necessary to rotate the adjustment handwheel 29 and change the relative position of the threaded adjustment seat 26 and the feedback shaft through the threaded transmission.
