Description

Technical Field

[0001] This invention relates to the field of steel cord processing and production, specifically to a steel cord rewinding tension regulator. Background Technology

[0002] Steel cord is made of high-quality high-carbon steel with a brass-plated surface, consisting of fine-gauge steel wire strands or ropes with special properties. It is mainly used as the reinforcing material for passenger car tires, light truck tires, heavy-duty truck tires, construction machinery tires, aircraft tires, and other rubber products. Radial tires made with steel cord as a reinforcing material have advantages such as long service life, high speed, puncture resistance, good elasticity, safety and comfort, and fuel efficiency.

[0003] Currently used steel cord rewinding machines occupy a large space, have uneven tension adjustment, and offer limited functionality, failing to adequately meet the speed and quality requirements for steel cord rewinding. Furthermore, the tension adjustment process is isolated from other processes, resulting in a lack of coordination between the traction, transfer, reversal, and winding actions. This structure necessitates multiple power sources during production, leading to an inefficient and large footprint. Moreover, current steel cord tension regulators cannot be integrated into the rewinding machine's spool; instead, the traction mechanism is used to wind the steel cord around the spool. This means that sudden tension changes cannot be addressed, necessitating machine shutdown for correction, resulting in low efficiency.

[0004] Therefore, it is necessary to design a steel cord rewinding tension regulator that integrates the functions of multiple traction rollers and uses a single power source to achieve traction, switching, reversing, and tension correction of the steel cord, thus avoiding excessive device size. Simultaneously, this device can also perform real-time detection and adjustment of the steel cord tension, improving work efficiency. Summary of the Invention

[0005] Therefore, it is necessary to provide a steel cord rewinding tension regulator to address the existing technical problems.

[0023] The beneficial effects of this invention compared to the prior art are:

[0024] Firstly, this device has a high degree of integration. It only requires adjusting one power source, the motor, to realize the rotation of the winding roller and the adjusting roller, as well as the movement of the I-beam wheel in two directions. The device has a compact structure, strong structural linkage, and a small footprint.

[0025] Secondly, this device uses the active movement of the I-beam wheel to achieve the winding of the steel cord, which makes the steel cord change passively, avoiding the sudden change in its own tension caused by the active change of the steel cord. At the same time, it can also make the steel cord evenly wound on the outside of the I-beam wheel.

[0026] Thirdly, this device uses a complementary method to counteract the tension of the steel cord, preventing the steel cord from being too tight or too loose when wrapped around the outside of the I-beam reel, which would affect subsequent processing and production, thus improving work efficiency.

[0036] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0037] refer to Figures 1 to 8 Steel cord rewinding tension regulator, including:

[0038] The I-beam reel 1 can evenly wind the steel cord;

[0039] Drive motor 2, the output end of which is coaxially keyed with I-beam wheel 1;

[0040] The positioning roller 5 is horizontally positioned beside the I-beam wheel 1;

[0041] The cable tension sensor 6 is connected to the center key of the positioning roller shaft 5;

[0042] Adjusting roller 4 is located on the side of positioning roller 5 away from I-beam 1;

[0043] The winding roller 3 is located on the side of the adjusting roller 4 away from the positioning roller 5;

[0044] Two clamping mechanisms 7 are keyed to the adjusting roller shaft 4 and the winding roller shaft 3, respectively;

[0045] The tension adjustment assembly 10 includes an adjustment motor 11, a buffer cylinder 24, a tension adjustment mechanism 29, and a reciprocating winding mechanism 43. The adjustment motor 11 is located beside the winding roller 3, the buffer cylinder 24 is located at the upper end of the adjustment roller 4, and the tension adjustment mechanism 29 is located at the lower end of the drive motor 2. The tension adjustment mechanism 29 can drive the I-beam 1 to move perpendicular to the axis direction. The reciprocating winding mechanism 43 is located at the lower end of the tension adjustment mechanism 29 and can drive the I-beam 1 to reciprocate at a constant speed in the axis direction.

[0046] During operation, the steel cord is initially positioned by the winding roller 3, then undergoes initial tension adjustment by the adjusting roller 4. Subsequently, it is monitored in real-time by the positioning roller 5 and the cable tension sensor 6. Finally, the steel cord is evenly wound around the outside of the I-beam 1 to prevent sudden tension changes due to uneven winding. During this process, the cable tension sensor 6 monitors the tension of the steel cord in real time. The adjusting motor 11 and the buffer cylinder 24 adjust their power based on this data. The buffer cylinder 24 drives the adjusting roller 4 to reciprocate vertically, providing initial tension adjustment during this movement. Subsequently, the adjusting motor 11, integrating multiple components, drives the I-beam 1 to perform two simultaneous displacements via the tension adjustment mechanism 29 and the reciprocating winding mechanism 43: a reciprocating movement perpendicular to the axis of the I-beam 1 and a reciprocating movement perpendicular to the axis of the I-beam 1.

[0047] To prevent the steel cord from detaching during traction, the following features are specifically designed:

[0048] Both clamping mechanisms 7 include two compression baffles 8 and two compression springs 9. The four compression baffles 8 are slidably and coaxially sleeved in pairs on the middle of the adjusting roller shaft 4 and the winding roller shaft 3. The four compression springs 9 are sleeved in pairs on the outside of the adjusting roller shaft 4 and the winding roller shaft 3. One end of each compression spring 9 abuts against the shaft end of the corresponding adjusting roller shaft 4 or the corresponding winding roller shaft 3, and the other ends of the four compression baffles 8 are fixedly connected to the corresponding four compression springs 9. During operation, because the steel cord will slide and deviate along the axis of the roller body when the traditional roller shaft pulls the steel cord, this process will cause errors in the processing of the steel cord. Therefore, the two compression springs 9 on the adjusting roller shaft 4 and the winding roller shaft 3 will move closer to each other under their own elastic force. At this time, the two compression baffles 8 connected to the two compression springs 9 will clamp the steel cord to prevent it from shifting.

[0049] To enhance the integration of this device, enabling the adjusting motor 11 to simultaneously drive the winding roller shaft 3 and the positioning roller shaft 5 to rotate, the following features are specifically provided:

[0050] The tension adjustment assembly 10 also includes a long power shaft 12, a power worm gear 13, a power worm wheel 14, a linkage pin 15, two power pulleys 16, and two power belts 17. The long power shaft 12 is axially connected to the output end of the adjustment motor 11 via a coupling. The power worm gear 13 is sleeved on the outside of the long power shaft 12. The power worm wheel 14 is located at the upper end of the power worm gear 13 and meshes with the power worm gear 13. One end of the linkage pin 15 is keyed to the power worm wheel 14, and the other end is keyed to the winding roller shaft 3. The two power pulleys 16 are respectively fixedly located at both ends of the winding roller shaft 3. One end of each of the two power belts 17 is connected to the two power pulleys 16 for transmission. When the device is running, the regulating motor 11 starts and drives the power shaft 12 connected to its output end to rotate. The rotation of the power shaft 12 will drive the power worm gear 13 connected to it to rotate. The rotation of the power worm gear 13 will drive the power worm wheel 14 meshing with it to rotate. The power worm wheel 14 drives the winding roller shaft 3 to rotate through the linkage pin 15. The rotation of the winding roller shaft 3 will drive the two power pulleys 16 connected to it to rotate. The rotation of the two power pulleys 16 will drive the two power belts 17 to transmit power respectively.

[0051] In order to enable the adjusting roller 4 to move vertically and thus allow for preliminary adjustment of the tension of the steel cord, the following features are specifically designed:

[0052] The tension adjustment assembly 10 also includes a linkage support plate 23, a driven pin 20, two driven pulleys 18, two tensioners 19, two limit supports 21, and two limit sleeves 22. The two driven pulleys 18 are respectively located at both ends of the adjustment roller shaft 4. The other ends of the two power belts 17 are respectively connected to the two driven pulleys 18. The two tensioners 19 are respectively located at the upper ends of the two power belts 17 and abut against the two power belts 17. The driven pin 20 is keyed to the adjustment roller shaft 4. The two limit supports 21 are respectively located at both ends of the adjustment roller shaft 4. The two limit sleeves 22 are respectively rotatably sleeved with both ends of the driven pin 20. The two limit sleeves 22 are also slidably connected to the two limit supports 21. The linkage support plate 23 is fixedly connected to the upper ends of the two limit sleeves 22. The middle part of the linkage support is fixedly connected to the output end of the buffer cylinder 24. During operation, the two power belts 17 drive the two driven pulleys 18 to rotate. The rotation of the two driven pulleys 18 drives the connected adjusting roller shaft 4 to rotate, thus completing the initial traction of the steel cord. This allows the steel cord to be input into the cable tension sensor 6 sleeved on the positioning roller shaft 5 via the adjusting roller shaft 4. During this process, the cable tension sensor 6 can monitor the tension value of the steel cord in real time. Based on the real-time tension value of the steel cord, the buffer cylinder 24 is activated. The output end of the buffer cylinder 24 drives the linkage support plate 23 to move vertically. The movement of the linkage support plate 23 in the straight direction will cause the two limit sleeves 22 connected to it to move. The two limit sleeves 22 will cause the driven pin 20 rotatably connected to them to move. The movement of the driven pin 20 will cause the adjusting roller shaft 4 connected to it to move. At this time, the steel cord wrapped around the outside of the adjusting roller shaft 4 will be tensioned as the adjusting roller shaft 4 moves. During this process, the two tensioners 19 will act on the outside of the two power belts 17 respectively to prevent the two power belts 17 from becoming loose and affecting the transmission.

[0053] In order for the H-beam wheel 1 to move normally under the action of the tension adjustment mechanism 29, the following features are specifically designed:

[0054] The tension adjustment assembly 10 also includes a driving bevel gear 25, a driven bevel gear 26, a driving pulley 27, and a universal joint 28. The driving bevel gear 25 is keyed to the end of the power shaft 12 away from the adjusting motor 11. The driven bevel gear 26 is located at the lower end of the driving bevel gear 25 and meshes with it. The driving pulley 27 is coaxially fixedly located at the lower end of the driven bevel gear 26. The driving pulley 27 and the driven bevel gear 26 are connected by a short pin. The universal joint 28 is located at the end of the driving bevel gear 25 away from the adjusting motor 11, and one end of the universal joint 28 is fixedly connected to the driving bevel gear 25. When the device is running, the rotation of the power shaft 12 will drive the connected driving bevel gear 25 to rotate. The rotation of the driving bevel gear 25 will drive the connected universal joint 28 to rotate. At the same time, the driving bevel gear 25 will also drive the meshing driven bevel gear 26 to rotate. The rotation of the driven bevel gear 26 will drive the connected driving pulley 27 to rotate. Universal joint 28 can change the direction of power transmission of the long shaft 12, so that the I-beam wheel 1 can be displaced in the axial direction under the action of tension adjustment mechanism 29.

[0055] To avoid neutralizing the sudden tension changes that occur during the winding process of the steel cord, and to ensure that the steel cord can maintain a balance between profit and loss within a certain range, the following features are specifically designed:

[0056] The tension adjustment mechanism 29 includes a moving platform 30, a support top platform 42, a reciprocating screw 32, a positioning rod seat 34, a linkage rod seat 33, a linkage rod sleeve 35, a linkage fork 36, four support bases 37, four linkage support rods 38, four support top seats 39, two first linkage shafts 40, and two second linkage shafts 41. The support top platform 42 is fixedly installed at the lower end of the drive motor 2. The four support top seats 39 are respectively suspended at the lower end of the support top platform 42. The four support bases 37 are respectively positioned below the four support top seats 39. The moving platform 30 is fixedly installed at the lower end of the four support bases 37. The two ends of the two first linkage shafts 40 are keyed to the four support top seats 39. The two second linkage shafts 41 are respectively connected to the four support top seats 39. The two linkage shafts 41 are keyed to the four support bases 37 respectively. The upper ends of the four linkage rods 38 are keyed to the two first linkage shafts 40 respectively, and the lower ends are keyed to the two second linkage shafts 41 respectively. The linkage rod seat 33 is fixedly set at the upper end of the moving platform 30. One end of the reciprocating screw 32 is threadedly connected to the linkage rod seat 33, and the other end is fixedly shafted to the end of the universal joint 28 away from the active bevel gear 25. The positioning rod seat 34 is set on the side of the linkage rod seat 33. The positioning rod seat 34 is slidably connected to the unthreaded part of the reciprocating screw 32. The linkage rod sleeve 35 is fixedly sleeved on the outside of the reciprocating screw 32. The lower end of the linkage fork 36 is hinged to the linkage rod sleeve 35, and the upper end is hinged to the first linkage shaft 40. During operation, the rotation of the universal joint 28 drives the reciprocating screw 32 to rotate, which in turn moves back and forth along the axial direction. The reciprocating screw 32 then moves the linkage fork 36 via the linkage sleeve 35. The linkage fork 36, in turn, moves the support top platform 42 back and forth via the first linkage shaft 40 and the support base 37. During this process, the tension of the steel cord wound on the I-beam 1 remains within a certain range, ensuring that the tension of the steel cord is stable within the optimal range and preventing the winding result from being affected by excessive tension or slack. It is important to note that there should be a sliding limit perpendicular to the axial direction between the wheel seat used to mount the I-beam 1 and the I-beam 1 to prevent the I-beam 1 from failing to move synchronously with the support top platform 42.

[0057] To prevent the steel cord from winding unevenly on the I-beam spool 1 and affecting subsequent processing, the following features are specifically designed:

[0058] The mobile platform 30 has a mobile groove 31 formed on it. The reciprocating winding mechanism 43 includes a positioning platform 50, a reciprocating gear 54, a limiting connecting shaft 56, a curved gear ring 53, two limiting slides 51 and two limiting slide rails 52. The positioning platform 50 is located below the mobile platform 30. The two limiting slide rails 52 are fixedly located at the lower end of the mobile platform 30. The two limiting slides 51 are fixedly located at the upper end of the positioning platform 50. The two limiting slide rails 52 are slidably connected to the two limiting slides 51 respectively. The lower end of the limiting connecting shaft 56 is fixedly inserted into the positioning platform 50, and the upper end is slidably connected to the mobile groove 31. The curved gear ring 53 is fixedly located at the lower end of the mobile platform 30. The reciprocating gear 54 is keyed to the limiting connecting shaft 56. The reciprocating gear 54 has meshing teeth 55 evenly arrayed along the minor arc direction. The reciprocating gear 54 meshes with the curved gear ring 53 through the meshing teeth 55. During operation, the reciprocating gear 54 rotates. The specific reason for this rotation will be explained later. When the meshing teeth 55 on the reciprocating gear 54 mesh with the curved gear ring 53, since the meshing teeth 55 are only half the size of those on a normal gear, the meshing teeth 55 on the reciprocating gear 54 will mesh with the teeth on the curved gear ring 53 intermittently. At this time, the curved gear ring 53 will move back and forth at a constant speed. This reciprocating movement of the curved gear ring 53 will drive the moving platform 30, which is fixed to it, to move back and forth at a constant speed. The reciprocating displacement of the moving platform 30 will drive the I-beam wheel 1 to move back and forth along its axial direction. During the back and forth movement of the I-beam wheel 1, the steel cord can be evenly wound around the I-beam wheel 1, avoiding uneven winding of the steel cord on the I-beam wheel 1, which would affect subsequent processing.

[0059] In order to comprehensively adjust the output power of the motor 11 and enhance the overall compactness of the device, so that the adjusting motor 11 can drive the reciprocating gear 54 to rotate, the following features are specifically provided:

[0060] The reciprocating winding mechanism 43 also includes a drive belt 44, a linkage pulley 45, a linkage pin 46, a drive pulley 47, a connecting belt 48, and a connecting pulley 49. One end of the drive belt 44 is connected to the drive pulley 27. The drive pulley 47 is located at the upper end of the positioning platform 50. The other end of the drive belt 44 is connected to the drive pulley 47. The upper part of the linkage pin 46 is keyed to the drive pulley 47. The connecting pulley 49 is coaxially located at the lower part of the drive pulley 47. The connecting pulley 49 is keyed to the lower part of the linkage pin 46. The linkage pulley 45 is coaxially located with the reciprocating gear 54. The linkage pulley 45 is keyed to the lower part of the limit connecting shaft 56. One end of the connecting belt 48 is connected to the linkage pulley 45, and the other end is connected to the connecting pulley 49. The drive pulley 27 drives the drive pulley 47 to rotate via the drive belt 44. The drive pulley 47 drives the connecting pulley 49 to rotate via the linkage pin 46. The connecting pulley drives the linkage pulley 45 to rotate via the connecting belt 48. The linkage pulley 45 drives the reciprocating gear 54 to rotate via the limit connecting shaft 56.

[0061] The working principle of this device is as follows: During actual production, the tension of the steel cord needs to be adjusted in real time due to its material properties and processing environment. In this process, the adjusting motor 11 starts, first driving the winding roller 3 to rotate via the cooperation of the power worm gear 13 and the power worm wheel 14. The position of the winding roller 3 remains fixed to ensure that the steel cord does not shift when input into the device. Subsequently, the winding roller 3 drives the adjusting roller 4 to rotate via the power belt 17. As mentioned above, the tension of the steel cord needs to be adjusted in real time during actual production. Therefore, the adjusting roller 4 can move vertically under the action of the buffer cylinder 24. During this movement, the steel cord connected to the adjusting roller 4 will tighten or loosen, that is, the tension of the steel cord will increase or decrease accordingly.

[0062] The steel cord is then fed into the cable tension sensor 6 via the positioning roller 5. The cable tension sensor 6 is existing technology and will not be described in detail. The cable tension sensor 6 can detect the tension parameters of the steel cord in real time, and the buffer cylinder 24 and the adjusting motor 11 can change their output power according to these parameters.

[0063] To prevent frequent abrupt changes in tension of the steel cord as it winds on the I-beam spool 1, the drive shaft 12 rotates the universal joint 28 and, through the reciprocating screw 32, moves the I-beam spool 1 within a small range. This movement cancels out the abrupt changes in the steel cord's tension, neutralizing any extra tension caused by tightening or loosening. Simultaneously, to ensure the steel cord is evenly wound around the outside of the I-beam spool 1, the driving bevel gear 25 and driven bevel gear 26 work together to divert power from the drive shaft 12 to the reciprocating gear 54. The reciprocating gear 54 engages with the curved gear ring 53, causing the I-beam spool 1 to reciprocate along its axial direction. During this reciprocating motion, the steel cord is evenly wound around the outside of the I-beam spool 1, preventing sudden tension changes due to uneven winding.
