Description

Technical Field

[0001] The present invention relates to the technical field of tension adjustment, and specifically to a device and method for installing and adjusting a tension roller for hand-tearable steel. Background Technique

[0002] Thin hand-tearable steel, as a highly precise and extremely technically difficult metal material, has a profound foundation in material science and manufacturing technology. This kind of steel, with its ultra-thin, high-strength, high-toughness, and easy-to-process and form characteristics, shows great application potential in high-end fields such as aerospace, precision instruments, and electronic components, and is known as the "black technology" in the field of material science. The tension roller converts the torque acting on it by the driving device into the tension of the strip through the friction between the roller surface and the strip, and when winding the hand-tearable steel, it is necessary to adjust the winding tension.

[0003] Before winding the hand-tearable steel, it is necessary to straighten the hand-tearable steel between the tension roller and the fixed roller first. At this time, it is necessary to adjust the position of the tension roller so that the tension roller presses the hand-tearable steel. However, if the moving distance of the tension roller is too long during the adjustment process, resulting in a large tension on the hand-tearable steel, it is very easy to damage the hand-tearable steel at this time, and it is extremely difficult to control the pressing effect of the tension roller on the hand-tearable steel, thus affecting the tension adjustment.

[0013] As a further solution of the present invention: The centers of the first inner connecting ring, the second inner connecting ring, the positioning ring, and the tension roller are coaxial.

[0014] The present invention also discloses a method for installing and adjusting a tension roller for hand-tearing steel. Using the above-mentioned device for installing and adjusting a tension roller for hand-tearing steel, it includes the following steps: S1: First, pass the hand-tearing steel through between the fixed roller and the tension roller; S2: Then, the tension roller is moved downward by operating the second-stage adjustment member, so as to move the tension roller toward the hand-tear steel between the fixed roller and the tension roller; S3: After the positioning roller contacts the hand-tear steel, the tension roller continues to move downward. At this time, the positioning roller will move upward relative to the tension roller under the action of the positioning disconnector. At the same time, the positioning roller rotates to the top of the tension roller. At this time, the tension roller is closer to the hand-tear steel. S4: By operating the two-stage adjustment piece, the tension roller is slowly brought closer to the hand-torn steel, and the tension on the hand-torn steel is adjusted in conjunction with the tension sensor and display.

[0015] The beneficial effects of the present invention are as follows: by setting a two-stage adjustment part and a positioning disconnect part, the toggle shaft drives the first adjustment screw to rotate through the buckle and the docking disk, so that the first movable slider drives the second connecting seat to move. As the tension roller moves downward, the positioning disconnect part operates. At this time, the annular electromagnet is energized, the buckle is separated from the docking disk, and the first adjustment screw cannot rotate. At this time, the worm is toggled to make the tension roller move slowly downward. During the downward movement, the tension roller will contact the hand-tear steel. At this time, the tension of the hand-tear steel during the winding process can be clearly known by watching the display, thereby preventing the tension roller from moving downward too much in a single time and causing damage to the hand-tear steel.

[0016] By setting a positioning disconnector, when the positioning roller contacts the hand-tear steel and the tension roller continues to move downward, the shift pin will be inserted into the second positioning hole, and the shift pin will lose its limit. At this time, the torsion spring will drive the first inner ring to rotate and restore under the action of the elastic restoring force, so that the first inner ring drives the positioning roller to the top of the tension roller. At this time, the outer ring will lift the pressing frame through the oblique connecting rod, and the warning light and the annular electromagnet will be energized. The warning light will light up, and the toggle shaft will lose the connection with the first adjusting screw. After that, the position of the tension roller can be fine-tuned by twisting the worm, so as to improve the accuracy of the tension roller position adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the present application.

[0022] Embodiment 1 Please refer to Figures 1 to 8 , a device for installing and adjusting a tension roller of hand-tearable steel, comprising a base 1. A first connecting seat 2 is installed on the top of the base 1. A support frame 3 is installed on the top of the first connecting seat 2. A two-stage adjusting member is arranged inside the first connecting seat 2. One side of the first connecting seat 2 is connected to a U-shaped connecting block 19 through the two-stage adjusting member. A positioning frame 5 is installed inside the U-shaped connecting block 19. A tension roller 21 is arranged inside the positioning frame 5. Side connecting seats 7 are installed on both sides of the first connecting seat 2. A fixed roller 8 is installed at one end of the side connecting seat 7. A tension sensor 6 connected to the tension roller 21 is arranged outside the positioning frame 5. A display 4 connected to the tension sensor 6 is installed on one side of the base 1 away from the first connecting seat 2. A position measuring and disconnecting member is arranged outside the tension roller 21. A position measuring roller 29 is connected to the tension roller 21 through the position measuring and disconnecting member.

[0023] In this embodiment: When winding the hand-tearable steel, first pass the hand-tearable steel through between the fixed roller 8 and the tension roller 21, and then operate the two-stage adjusting member to move the tension roller 21 downward, so as to make the tension roller 21 move towards the hand-tearable steel between the fixed roller 8 and the tension roller 21. When the position measuring roller 29 contacts the hand-tearable steel, the tension roller 21 continues to move downward. At this time, the position measuring roller 29 will move upward relative to the tension roller 21 under the action of the position measuring and disconnecting member, and at the same time, the position measuring roller 29 rotates above the tension roller 21. At this time, the tension roller 21 is relatively close to the hand-tearable steel. Then operate the two-stage adjusting member to make the tension roller 21 slowly approach the hand-tearable steel, so as to adjust the tension of the hand-tearable steel.

[0024] Embodiment 2 Please refer to Figure 1 , Figure 5 , Figure 6 Figure 7 , Figure 8, the two-stage adjusting member includes a rotary guide disk 13 rotatably connected to the top of the support frame 3. A toggle shaft 14 penetrating the rotary guide disk 13 is provided at the top of the rotary guide disk 13. A first telescopic spring 12 connected to the support frame 3 is provided at the bottom of the toggle shaft 14. An annular electromagnet 39 is rotatably connected to the outer side of the bottom of the toggle shaft 14 through a bearing. A guide rod 45 slidably connected to the support frame 3 is provided at the top of the annular electromagnet 39. A buckle 47 is installed at the bottom of the toggle shaft 14. A first adjusting screw rod 10 is rotatably connected to the inner side of the first connecting seat 2. A first movable slider 9 slidably connected to the first connecting seat 2 is movably sleeved on the first adjusting screw rod 10. A docking disk 46 located inside the support frame 3 is provided at the top of the first adjusting screw rod 10. A magnetic attraction block 11 is provided on the outer side of the docking disk 46. A second connecting seat 43 is installed on one side of the first movable slider 9. A second adjusting screw rod 44 is rotatably connected to the inner side of the second connecting seat 43 through a bearing. A second movable slider 41 is movably sleeved on the second adjusting screw rod 44. A U-shaped connecting block 19 is installed on the side of the second movable slider 41 away from the first movable slider 9. A worm gear 42 is installed at the top of the second adjusting screw rod 44. A worm 40 meshing with the worm gear 42 is provided at the top of the second connecting seat 43.

[0025] A jack matching the buckle 47 is provided at the top of the docking disk 46. The magnetic attraction block 11 and the center of the annular electromagnet 39 are coaxial. By setting this structure, the annular electromagnet 39 contacts the magnetic attraction block 11 under the action of the magnetic attraction block 11 when the annular electromagnet 39 is not energized, so that the buckle 47 is inserted into the top of the docking disk 46. At the same time, the annular electromagnet 39 repels the magnetic attraction block 11 when it is energized, so as to separate the magnetic attraction block 11 from the annular electromagnet 39.

[0026] The pitch on the first adjusting screw rod 10 is greater than the pitch on the second adjusting screw rod 44. The two ends of the worm 40 are in a knob structure. By setting this structure, the angle of single rotation of the worm 40 is prevented from being too large. At the same time, the activity range of the second movable slider 41 is reduced by reducing the pitch on the surface of the second adjusting screw rod 44, so as to realize the slow downward movement of the second movable slider 41 and prevent the accuracy of the position adjustment of the tension roller 21 from being affected due to the too fast downward movement speed of the second movable slider 41.

[0027] In this embodiment: when adjusting the tension roller 21, the toggle shaft 14 is first rotated. At this time, since the annular electromagnet 39 is in contact with the magnetic block 11, the rotation of the toggle shaft 14 causes the rotary guide plate 13 to rotate relative to the support frame 3. At the same time, the toggle shaft 14 drives the first adjusting screw 10 to rotate through the buckle 47 and the docking plate 46, so that the first movable slider 9 drives the second connecting seat 43 to move, thereby causing the tension roller 21 to move downward. As the tension roller 21 moves downward, the positioning disconnector operates, and the annular electromagnet 39 is energized, thereby separating the annular electromagnet 39 from the magnetic block 11. At this time The buckle 47 will be separated from the docking plate 46, so that when the toggle shaft 14 is rotated, the first adjusting screw 10 cannot rotate relative to the first connecting seat 2. At this time, the worm 40 is toggled, and the worm 40 will drive the second adjusting screw 44 to rotate through the worm gear 42, so that the second movable slider 41 drives the U-shaped connecting block 19 to move downward, thereby causing the tension roller 21 to move downward slowly. During the downward movement, the tension roller 21 will contact the hand-tear steel. At this time, by watching the display 4, the tension of the hand-tear steel during the winding process can be clearly known, thereby preventing the tension roller 21 from moving downward too much in a single time and causing damage to the hand-tear steel.

[0028] Example 3 See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5, the position measuring disconnection part includes positioning rings 17 installed inside the positioning frame 5 and located at both ends of the tension roller 21. A first positioning hole 30 is provided on the positioning ring 17 and located below the tension roller 21. A fixed disk 18 is connected to one side of the positioning frame 5. A first inner connecting ring 23 is rotatably connected to the inner side of the fixed disk 18. A torsion spring 34 is provided between the first inner connecting ring 23 and the fixed disk 18. A transposition pin 27 penetrating the first inner connecting ring 23 is inserted into one side of the first inner connecting ring 23. A fourth telescopic spring 36 connected to the transposition pin 27 is arranged inside the first inner connecting ring 23. A plug rod 28 is inserted into the side of the first inner connecting ring 23 away from the positioning ring 17. The position measuring roller 29 is installed at the bottom of the plug rod 28 and located below the tension roller 21. A second positioning hole 35 is provided on the plug rod 28. A pressing frame 16 is slidably connected to the positioning frame 5. The bottom of the pressing frame 16 is rotatably connected to an inclined connecting rod 22 through a rotating shaft. The bottom end of the inclined connecting rod 22 is rotatably connected to an outer connecting ring 25 located between the first inner connecting ring 23 and the positioning ring 17 through a rotating shaft. The inner wall of the outer connecting ring 25 is rotatably connected to a second inner connecting ring 24 through a bearing. The transposition pin 27 penetrates the second inner connecting ring 24 and is fixedly connected to the second inner connecting ring 24. One end of the transposition pin 27 is provided with a vertical plate 31 located between the second inner connecting ring 24 and the positioning ring 17. A locking pin 32 extending into the first positioning hole 30 is inserted into the bottom of the vertical plate 31. A third telescopic spring 33 connected to the vertical plate 31 is arranged on the side of the locking pin 32 away from the positioning ring 17. A positioning bin 15 is installed on the top of the positioning frame 5. A warning light 20 is installed on the top of the positioning bin 15. A first contact piece 37 located inside the positioning bin 15 is arranged on the pressing frame 16. A second contact piece 38 located above the first contact piece 37 is installed on the inner wall of the positioning bin 15. Second telescopic springs 26 connected to the positioning frame 5 are arranged on both sides of the outer connecting ring 25.

[0029] The first contact piece 37 is electrically connected to an external power supply through a wire. The second contact piece 38 is electrically connected to the warning light 20 and the annular electromagnet 39 through a wire. By setting this structure, when the first contact piece 37 contacts the second contact piece 38, the warning light 20 and the annular electromagnet 39 operate synchronously, so as to control the operation timing of the warning light 20 and the annular electromagnet 39.

[0030] One end of the transposition pin 27 away from the vertical plate 31 is rotatably connected to a ball through a rotating shaft. The diameter of the second positioning hole 35 is equal to that of the transposition pin 27. By setting this structure, the friction between the transposition pin 27 and the plug rod 28 is reduced, and at the same time, the stability of the position measuring roller 29 after the transposition pin 27 is inserted into the second positioning hole 35 is improved.

[0031] The locking pin 32 is slidably connected to the vertical plate 31, and the locking pin 32 is equal to the diameter of the first positioning hole 30. By setting this structure, the shift pin 27 is separated from the second positioning hole 35 when the pressing frame 16 is pressed, and the third telescopic spring 33 is stretched. Then, by moving the positioning roller 29 to the bottom of the tension roller 21, the second positioning hole 35 is misaligned with the shift pin 27 under the action of the positioning roller 29's own gravity. At the same time, the locking pin 32 is aligned with the first positioning hole 30 and is inserted into the first positioning hole 30 under the action of the elastic restoring force of the third telescopic spring 33, so as to fix the positioning roller 29 that is rotated to the bottom of the tension roller 21, thereby providing convenience for subsequent use.

[0032] The first inner ring 23, the second inner ring 24, the positioning ring 17, and the tension roller 21 are coaxial. By setting this structure, the positioning roller 29 always rotates around the center of the tension roller 21 when rotating, thereby preventing the positioning roller 29 from deviating when it rotates above the tension roller 21.

[0033] It should be noted that, in the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0034] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0035] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
