Abstract
Description
Technical Field
[0001] This invention relates to the field of uncoiler technology, specifically a highly stable anti-scratch uncoiler. Background Technology
[0002] An uncoiler is a specialized piece of equipment for leveling metal sheets. The machine body is a welded box-shaped structure. A variable frequency speed-regulating motor drives the drum shaft through a gearbox to provide the main power for the uncoiler.
[0003] Existing uncoilers generally face technical bottlenecks in the coil processing process, including insufficient stability and poor anti-scratching effect. Specific defects are as follows: First, the expansion and contraction drums of existing uncoilers mostly use a single drive source to drive the radial movement of the sector plates. The lack of mechanical rigid linkage between the sector plates makes it easy for asynchronous expansion and contraction to occur due to transmission gaps or uneven force. In addition, in the existing technology, the support during the coil unfolding process mostly relies on fixed rollers or single-sided pressure arms, which makes it difficult to adaptively adjust the support force according to changes in the coil diameter. When the coil diameter decreases, the contact stress between the rollers and the coil increases sharply, which can easily cause material wrinkles or local indentations. At the same time, the coil is also prone to radial runout due to eccentric rotation, which can lead to friction and scratching between the coil edge and the frame. Furthermore, the limiting mechanisms on both sides are mostly fixed baffles, which are also difficult to adapt to coils of different widths. This can further lead to "over-limiting" causing edge scratches or "under-limiting" causing the coil to fall off. Summary of the Invention

The outer surface of the rotating irregular plate located between the concave arc grooves is provided with an inner sliding groove.
[0018] Optionally, the inter-agency mechanism includes:
[0019] A first gear is fixedly sleeved outside the output end of the second motor. A protruding frame plate is fixedly installed on the other side surface of the uncoiler body near the leveler. An extension frame is fixedly installed on one side surface of the protruding frame plate. A linkage rod is inserted between the protruding frame plate and the extension frame. A second gear is fixedly sleeved at the end of the linkage rod away from the extension frame. An internal gear belt meshes between the first gear and the second gear.
[0020] The first limiting roller is fixedly sleeved on the outer surface of the linkage rod near the second gear. A threaded groove is opened on the outer surface of the other side of the linkage rod. The second limiting roller is threadedly sleeved in the threaded groove.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0026] I. The expansion and contraction adjustment mechanism of the present invention adopts a pure mechanical transmission chain of a first threaded rod, a threaded sleeve plate, a lower moving frame plate, and a hinged rod, combined with a sliding rod guide and spring preload, to achieve synchronous radial expansion and contraction of four sets of sector plates. The sliding engagement between the first groove of the cross slide plate and the sliding plate of the sector plate further restricts the non-radial displacement of the sector plates, avoiding the "tilting and scraping" caused by unilateral force in traditional structures. The spring is wound around the outside of the slide rod, which can compensate for the small tolerance range of the inner hole of the roll material through elastic deformation, reducing the fluctuation of clamping force. This avoids both excessive tightness leading to plastic deformation of the inner hole and excessive looseness causing sliding friction.
[0027] Second, the transverse movement mechanism of the present invention drives the second threaded rod and the sliding frame through the threaded transmission of the second motor, and cooperates with the rigid guide of the fixed slide frame, which can greatly improve the positioning accuracy of the frame transverse movement. Furthermore, the upper pressure roller frame and the lower support roller frame can adjust the pressure of the pressure roller / support roller in real time according to the diameter of the roll material through the linkage of the first rotating shaft, the first rotating sleeve, the second rotating sleeve, the first hydraulic cylinder and the second hydraulic cylinder, so as to avoid indentation caused by local stress concentration. In addition, the adjustment mechanism drives the second limit roller to move synchronously through the threaded groove of the linkage rod and the second slide groove of the slider, thereby adapting to the change of the roll material width, preventing edge scratches and avoiding the transverse movement of the roll material caused by high-speed operation.
[0028] Third, the auxiliary mechanism of the present invention meshes with the frame tooth plate through the auxiliary gears on the upper and lower sides of the uncoiler body to form a "gear-rack" rigid transmission pair. In conjunction with the arc surface of the convex and concave circular plates and the sliding damping of the circular block plate and the inner sliding groove, the vibration amplitude during the transverse movement of the frame is reduced.

Detailed Implementation
[0041] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0042] Example 1, please refer to Figures 1 to 11 This invention provides a technical solution: a highly stable anti-scratch uncoiler, comprising a base plate 1, a second motor 21, an uncoiler body 2, and a leveler 3 fixedly mounted on the upper surface of the base plate 1; a first motor 5 fixedly mounted on one side surface of the uncoiler body 2; a frame 26 slidably mounted on the other side surface of the uncoiler body 2; a bevel gear 6 fixedly connected to the output end of the first motor 5; a bevel gear roller 7 meshing with the teeth of the bevel gear 6; and a housing 4 fixedly mounted on one side surface of the uncoiler body 2. The output end of a motor 5 is inserted inside the housing 4, and the gear ends of the bevel gear 6 and the bevel gear roller 7 are both located inside the housing 4. The surface of the bevel gear roller 7 is sequentially fixedly fitted with a cross slide plate 8 and a roll 9. Four sets of fan-shaped plates 17 are slidably arranged inside the cross slide plate 8. A roll 20 is clamped between the outer surfaces of the four sets of fan-shaped plates 17. A first limiting roller 43 and a second limiting roller 48 are symmetrically arranged on both sides of the roll 20. An upper pressure roller frame 35 and a lower support roller frame 37 are arranged on the other two sides of the roll 20.
[0043] The inside of the roll 9 is provided with an expansion and contraction adjustment mechanism so that the sector plate 17 can slide in an expansion and contraction adjustment manner on the four sides of the roll 9. The sliding movement is limited by the sliding of the sector plate 17 in the cross slide plate 8, and the rolls 20 of different specifications are clamped and fixed.
[0044] A transverse mechanism is fixedly installed on the upper surface of the bottom plate 1 located below the frame 26. The transverse mechanism is connected to the second motor 21 to convert the power of the second motor 21 into the transverse movement of the frame 26, and simultaneously drive the upper pressure roller frame 35 and the lower support roller frame 37 to adjust their positions, thereby adaptively pressing and lifting the roll material 20 of different width specifications.
[0045] The uncoiling machine body 2 is equipped with auxiliary mechanisms on the symmetrical upper and lower sides of the frame 26, so that the frame 26 can be further assisted in limiting and perform highly stable lateral movement.
[0046] The transverse movement mechanism is connected to an adjustment mechanism so that the second limit roller 48 moves in a synchronous manner. It is adapted to the adjustment gap of the upper pressure roller frame 35 and the lower support roller frame 37, and performs limit adjustment on both sides to prevent the roll material 20 of different specifications from falling off.
[0047] More specifically, in this embodiment, the first motor 5 is started first. The output end of the first motor 5 drives the bevel gear 6 to rotate, which drives the bevel gear roller 7 to rotate through tooth meshing. This, in turn, drives the fixedly sleeved cross slide plate 8 and the roll 9 to rotate synchronously. The four sets of fan-shaped plates 17 clamp the inner hole of the roll material 20 through the expansion and contraction adjustment mechanism. The two sides of the roll material 20 are symmetrically limited by the first limiting roller 43 and the second limiting roller 48. The other two sides are pressed and lifted by the upper pressure roller frame 35 and the lower support roller frame 37. The roll 9 drives the roll material 20 to rotate and unfold under the drive of the first motor 5. After unfolding, the roll material is guided by the upper pressure roller frame 35 and the lower support roller frame 37 and then enters the leveling machine 3 for leveling.
[0048] Among them, the outer surface of the fan-shaped plate 17 is in surface contact with the inner hole of the roll material 20. With the flexible support of the upper pressure roller frame 35 and the lower support roller frame 37, the local stress concentration caused by point contact is avoided, and the scratch rate of the roll material surface is reduced.
[0049] Furthermore, the inflation and deflation control mechanisms include:
[0050] A first threaded rod 10 is inserted into the inner bottom wall of the drum 9. The other end of the first threaded rod 10 extends to the outside of the drum 9 and is fixedly connected to a handle 11. Four sliding rods 13 are fixedly connected to the bottom wall of the drum 9. A threaded sleeve plate 12 is threadedly fitted onto the outer surface of the first threaded rod 10. A lower moving frame plate 14 is slidably provided on the outer surface of each sliding rod 13. The lower surface of the lower moving frame plate 14 is fixedly connected to the outer surface of the threaded sleeve plate 12. A spring 15 is fixedly connected between the lower moving frame plate 14 and the inner walls on both sides of the drum 9. The spring 15 is wound around the outside of the sliding rod 13. The other end of the lower moving frame plate 14 slides through to the outside of the drum 9. A hinge rod 16 is hinged between the two outer surfaces of the lower moving frame plate 14 and the fan-shaped plate 17.
[0051] A sliding plate 19 is fixedly connected to one side surface of the fan-shaped plate 17. A first groove 18 is opened on the surface of the cross-shaped sliding plate 8, and the sliding plate 19 slides inside the first groove 18.
[0052] It is worth noting that when encountering coils 20 with different inner diameters, the handle 11 needs to be rotated, which in turn drives the first threaded rod 10 to rotate. The threaded sleeve 12 moves along the axial direction of the threaded rod, simultaneously pushing the four sets of lowering frame plates 14 to slide along the slide rod 13. The lowering frame plates 14 push the sector plate 17 to extend radially through the hinge rod 16. The slide plate 19 on one side of the sector plate 17 slides in the first slide groove 18 of the cross slide plate 8 to achieve radial tension. Rotating the handle 11 in the opposite direction causes the spring 15 to rebound and drive the lowering frame plate 14 to reset, and the sector plate 17 to retract. When there is a small tolerance in the inner hole of the coil 20, the spring 15 absorbs the dimensional error through compression / rebound, ensuring that the clamping force of the sector plate 17 on the inner hole of the coil is constant.
[0053] Among them, the four sets of sliding rods 13 provide rigid guidance for the lowering frame plate 14, and in conjunction with the synchronous drive of the threaded sleeve plate 12, reduce the synchronous error of the expansion and contraction of the sector plate 17, and avoid the tilting problem of the sector plate 17 caused by the traditional single drive source. The precise fit between the first sliding groove 18 and the sliding plate 19 restricts the non-radial displacement of the sector plate 17. The spring 15 is wrapped around the outside of the sliding rod 13 to form a buffer, preventing the edge of the inner hole of the roll material from being plastically deformed or scratched due to rigid extrusion.
[0054] Furthermore, the lateral movement mechanism includes:
[0055] A fixed slide frame 23 is fixedly installed on the upper surface of the base plate 1. A slide frame 25 is slidably installed in the slide groove of the inner bottom wall of the fixed slide frame 23. The output end of the second motor 21 is fixedly connected to the second threaded rod 24. The slide frame 25 is threadedly sleeved on the outer surface of the second threaded rod 24. The frame 26 is fixedly connected to the lower surface of the slide frame 25.
[0056] Furthermore, auxiliary mechanisms include:
[0057] Short frame plates 50 are symmetrically fixedly connected to the upper and lower sides of the uncoiler body 2. Auxiliary gears 51 are inserted into the upper surface of each short frame plate 50. Toothed plates 49 are fixedly installed on the symmetrical surface of the frame 26 near the uncoiler body 2, and the auxiliary gears 51 are meshed with the toothed plates 49. A convex circular plate 52 is fixedly connected to the upper surface of the auxiliary gears 51. A concave circular plate 53 and a circular block plate 54 are fixedly connected to the upper surface of the convex circular plate 52, and the circular block plate 54 is fixedly connected to the raised upper surface of the convex circular plate 52.
[0058] The uncoiling machine body 2 has symmetrically inserted shafts 55 inside. A rotating irregular plate 56 is fitted on the outer surface of the shaft 55. Concave arc grooves 57 are symmetrically opened on the outer surfaces of both sides of the rotating irregular plate 56. An inner sliding groove 58 is opened on the outer surface of the rotating irregular plate 56 between the concave arc grooves 57. The concave arc grooves 57 are respectively rotated and attached to the two arc surfaces of the concave plate circular plate 53. The circular block plate 54 is slidably placed in the inner sliding groove 58.
[0059] It is worth noting that when dealing with rolls 20 of different specifications, the second motor 21 needs to be started. The output end of the second motor 21 drives the second threaded rod 24 to rotate. The sliding frame 25 slides along the slide groove in the fixed slide groove frame 23, and simultaneously drives the frame 26 to move laterally, thereby realizing the position adjustment of the upper pressure roller frame 35 and the lower support roller frame 37. When the frame 26 moves laterally, the toothed plate 49 on its surface meshes with the auxiliary gears 51 on the upper and lower sides of the uncoiler body 2, driving the convex circular plate 52 to rotate. The concave circular plate 53 on the convex circular plate 52 fits and rotates with the concave arc groove 57 of the rotating irregular plate 56. At the same time, the circular block plate 54 slides in the inner slide groove 58, forming a bidirectional damping limit.
[0060] Among them, the threaded transmission between the second threaded rod 24 and the sliding frame 25 improves the lateral positioning accuracy of the frame 26. The meshing of the auxiliary gear 51 and the toothed plate 49 eliminates the "creeping" phenomenon of traditional hydraulic cylinder drive. The arc surface fit between the concave plate circular plate 53 and the concave arc groove 57 further reduces the amplitude of lateral vibration. In addition, the high stability of the frame 26 ensures the alignment accuracy between the upper pressure roller frame 35 and the lower support roller frame 37 and the roll material 20, avoiding friction between the edge of the roll material 20 and the frame due to positional offset.
[0061] Furthermore, intermediary agencies include:
[0062] A first gear 22 is fixedly sleeved outside the output end of the second motor 21. A protruding plate 39 is fixedly installed on the other side surface of the uncoiling machine body 2 near the leveling machine 3. An extension frame 45 is fixedly installed on one side surface of the protruding plate 39. A linkage rod 40 is inserted between the protruding plate 39 and the extension frame 45. A second gear 41 is fixedly sleeved at the end of the linkage rod 40 away from the extension frame 45. An internal gear belt 42 meshes between the first gear 22 and the second gear 41.
[0063] The first limiting roller 43 is fixedly sleeved on the outer surface of the linkage rod 40 near the second gear 41. The other outer surface of the linkage rod 40 is provided with a threaded groove 44. The second limiting roller 48 is threadedly sleeved in the threaded groove 44. The inner bottom wall of the extension frame 45 is provided with a second sliding groove 46. A slider 47 is slidably provided inside the second sliding groove 46. The slider 47 is fixedly connected to the lower surface of the second limiting roller 48.
[0064] It is worth noting that when the output end of the second motor 21 drives the first gear 22 to rotate, it will transmit the power to the second gear 41 through the internal gear belt 42, thereby driving the linkage rod 40 to rotate. When the linkage rod 40 rotates, the second limiting roller 48 moves axially along the threaded groove 44, and the slider 47 at its bottom slides in the second slide groove 46 of the extension frame 45 to realize the gap adjustment between it and the first limiting roller 43, so as to adapt to different widths of roll material 20.
[0065] The synchronous transmission of the internal gear belt 42 ensures the synchronicity of the lateral movement of the second limiting roller 48 and the frame 26. The fixed first limiting roller 43 and the adjustable second limiting roller 48 cooperate to make the gap between the first limiting roller 43 and the second limiting roller 48 and the edge of the roll material 20 flexibly controlled. This avoids edge squeezing and scratching caused by "over-limiting" and prevents lateral movement of the roll material caused by "under-limiting", greatly reducing the risk of falling off.
[0066] Example 2, based on the above examples:
[0067] Furthermore, the surface of the frame 26 is interleaved with a first rotating shaft 27 and a second rotating shaft 28. The outer surfaces of the first rotating shaft 27 and the second rotating shaft 28 are respectively fitted with a first rotating sleeve 29 and a second rotating sleeve 30. The inner surface of the frame 26 is interleaved with a first hydraulic cylinder 33 and a second hydraulic cylinder 34. The output ends of the first hydraulic cylinder 33 and the second hydraulic cylinder 34 are respectively fixedly connected to a first recess 32 and a second recess 31. The inner surfaces of the first recess 32 and the second recess 31 are connected to the other ends of the first rotating sleeve 29 and the second rotating sleeve 30 through a sliding shaft.
[0068] The upper pressure roller frame 35 and the lower support roller frame 37 are respectively fixedly sleeved on the other end of the first rotating shaft 27 and the second rotating shaft 28 away from the frame 26. The upper pressure roller frame 35 is fixedly installed with an upper pressure roller 36 on one end of the roll material 20, and a number of support rollers 38 are installed at equal intervals on the inner surface of the lower support roller frame 37.
[0069] More specifically, in this embodiment, the first hydraulic cylinder 33 and the second hydraulic cylinder 34 are activated according to the pressing and lifting distance of the upper pressure roller frame 35 and the lower support roller frame 37 on the roll material. The output ends of the first hydraulic cylinder 33 and the second hydraulic cylinder 34 respectively push the first concave frame 32 and the second concave frame 31 to move, thereby driving the first rotating sleeve 29 and the second rotating sleeve 30 to rotate along the first rotating shaft 27 and the second rotating shaft 28, thereby adjusting the tilt angle of the upper pressure roller frame 35 and the lower support roller frame 37. The upper pressure roller 36 of the upper pressure roller frame 35 is in contact with the upper surface of the roll material 20, and the support roller 38 of the lower support roller frame 37 supports the lower surface of the roll material. The contact pressure is controlled by the stroke of the hydraulic cylinder.
