Description

Technical Field

[0001] The present invention relates to the technical field of aluminum coil coiling, and specifically to an aluminum coil coiling device. Background Art

[0002] The aluminum coil coiling device is a key equipment on the aluminum processing production line, which is used to wind the aluminum strip after being processed by processes such as rolling into an aluminum coil for storage, transportation and subsequent processing. The motor drives the reducer to operate, and the output shaft of the reducer drives the coiling mandrel to rotate. The aluminum strip is gradually wound into a coil under the drive of the mandrel.

[0003] The traditional coiling equipment only sets the motor drive to directly drive the mandrel to rotate. During the entire coiling process, the tension of the aluminum coil can only be adjusted by changing the speed of the motor, which results in a more complex control process of the entire equipment, lower reliability, and increased manufacturing and control costs. Therefore, it needs to be improved. Summary of the Invention

[0012] The present invention has the following beneficial effects:

[0013] Through the cooperation of the forward and backward movement of the conical wheel and the up and down movement of the tension roller, when the tension of the aluminum strip changes during the winding process, the winding speed of the aluminum strip is adaptively changed for adjustment, so that the aluminum strip can maintain the dynamic balance of tension during the coiling process. The entire adjustment process only requires the cooperation of the transmission components and does not require the cooperation of additional motors and sensors, which makes the stability of the entire dynamic balance better. And because the tension of the aluminum strip remains dynamically stable, even if the outer diameter gradually increases during the winding process of the mandrel, the dynamic balance effect itself can reduce the angular velocity of the mandrel, so that the aluminum strip remains stable during the entire coiling process, thereby improving the coiling effect.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In one embodiment, please refer to Figures 1 - 13, an aluminum coil winding device, comprising a substrate 1, a straightening component 4 is arranged at the end of the substrate 1, the straightening component 4 is arranged at the rightmost end of the substrate 1, and further comprises a winding driving mechanism 2 and a tension adjusting mechanism 3;

[0031] The winding driving mechanism 2 is arranged at the left end of the substrate 1 and comprises support side plates 21 vertically arranged on the front and rear sides of the upper surface of the substrate 1. The upper ends of the support side plates 21 are rotatably connected with a driven rotating shaft 32 arranged in the front and rear directions. One end of the driven rotating shaft 32 close to the center of the substrate 1 is provided with a main support roller 22. An auxiliary lifting component 33 is arranged on the left side of the support side plate 21. The auxiliary lifting component 33 and the main support roller 22 can support a mandrel 23 arranged in the front and rear directions. The mandrel 23 is arranged in the front and rear directions, and an aluminum strip 20 is wound around the outside of the mandrel 23. The middle part of the support side plate 21 is rotatably connected with a first rotating sleeve 29 arranged in the front and rear directions. The first rotating sleeve 29 and the driven rotating shaft 32 rotate synchronously. A second rotating sleeve 24 arranged in the front and rear directions is rotatably connected below the support side plate 21. The second rotating sleeve 24 and the first rotating sleeve 29 rotate synchronously. Therefore, the three rods of the first rotating sleeve 29, the second rotating sleeve 24 and the driven rotating shaft 32 all rotate synchronously to achieve the transmission effect;

[0032] The tension adjusting mechanism 3 includes a telescopic rod 63 slidably connected to one end of the first rotating sleeve 29 and the second rotating sleeve 24 away from the substrate 1. The telescopic rod 63 is arranged in the front-rear direction. One end of the telescopic rod 63 away from the substrate 1 is fixedly connected with a conical wheel 52. The conical wheel 52 has a frustum-shaped structure. The side of the conical wheel 52 close to the substrate 1 is an inclined surface. At one end of the first rotating sleeve 29 and the second rotating sleeve 24 away from the substrate 1, there is a blocking wheel 54 that cooperates with the conical wheel 52. A transmission belt 53 that rotates synchronously with the conical wheel 52 and the blocking wheel 54 is sleeved outside the two telescopic rods 63. The front and rear sides of the transmission belt 53 are respectively attached to the sides of the conical wheel 52 and the blocking wheel 54. Thus, due to the frictional force, the transmission belt 53 rotates synchronously with the conical wheel 52. By adjusting the distance between the conical wheel 52 and the blocking wheel 54, the rotation radius of the transmission belt 53 is changed, thereby changing the transmission ratio and achieving the effect of stepless speed change. For example, when the lower conical wheel 52 moves towards the blocking wheel 54, the rotation radius of the transmission belt 53 in contact with the conical wheel 52 increases. At this time, when the angular velocity of the lower conical wheel 52 remains unchanged, the angular velocity of the upper conical wheel 52 increases, thus achieving the effect of speed increase. By setting the taper of the blocking wheel 54, the blocking wheel 54 is in a relatively flat state. When adjusting the front and rear positions of the conical wheel 52, the distance between the conical wheel 52 and the transmission belt 53 changes. However, due to the blocking wheel 54 with a larger taper being arranged at the rear, the front and rear positions of the transmission belt 53 change less. Thus, when the front and rear positions of the conical wheel 52 are adjusted, the transmission belt 53 will not have the problem of tilting up and down, and the transmission belt 53 can continuously maintain the transmission effect. On the side of the substrate 1, there is an extension frame 61 arranged in the front-rear direction. At the end of the upper surface of the extension frame 61, a guide post 59 is vertically arranged. A counterweight sliding seat 57 is slidably connected to the middle of the guide post 59. A guide inclined groove 58 is arranged on one side of the counterweight sliding seat 57 close to the center of the substrate 1. A limiting rod 60 is slidably connected inside the guide inclined groove 58. The limiting rod 60 is rotatably connected to the side of the conical wheel 52. When the counterweight sliding seat 57 moves up and down, the limiting rod 60 moves along the guide inclined groove 58, thereby causing the conical wheel 52 to move back and forth. And since the limiting rod 60 and the conical wheel 52 are rotatably connected, although the conical wheel 52 remains in a rotating state, the cooperation between the guide inclined groove 58 and the limiting rod 60 can still drive the conical wheel 52 to move back and forth. On the front and rear sides of the middle of the substrate 1, there are vertically arranged tension support plates 39. A vertical sliding groove 40 is arranged in the middle of the tension support plates 39. A slider 41 is slidably connected to the sliding groove 40. The front and rear ends of a tension roller 42 arranged in the front-rear direction are rotatably connected to the slider 41. The aluminum strip 20 passes through the lower part of the tension roller 42, and the slider 41 and the counterweight sliding seat 57 move up and down synchronously.

[0033] In a case of this embodiment, hydraulic chambers 64 are provided inside both the first rotating sleeve 29 and the second rotating sleeve 24. A telescopic rod 63 is slidably connected to the hydraulic chamber 64, and hydraulic oil cooperating with the telescopic rod 63 is provided inside the hydraulic chamber 64. The end portions of the first rotating sleeve 29 and the second rotating sleeve 24 are respectively connected to the upper and lower ends of a hydraulic pipe 62. By providing the hydraulic pipe 62, the pressure balance between the upper and lower hydraulic chambers 64 is achieved. Therefore, when the lower conical wheel 52 moves toward the direction close to the blocking wheel 54, the upper conical wheel 52 moves away from the blocking wheel 54. At this time, the angular velocity of the upper first rotating sleeve 29 increases. On the contrary, after the lower conical wheel 52 moves away from the blocking wheel 54, the upper conical wheel 52 moves toward the direction close to the blocking wheel 54, so that the angular velocity of the upper first rotating sleeve 29 decreases, thereby achieving the effect of rapid speed regulation.

[0034] In a case of this embodiment, the side of the guiding inclined groove 58 away from the substrate 1 is inclined toward the direction close to the conical wheel 52, and the upper part of the guiding inclined groove 58 is inclined toward the direction of the conical wheel 52. The limiting rod 60 slides along the inside of the guiding inclined groove 58. Therefore, when the tension of the aluminum strip 20 decreases, the tension roller 42 moves downward, the counterweight sliding seat 57 moves downward by gravity, and the guiding inclined groove 58 moves downward. At this time, the guiding inclined groove 58 pushes the limiting rod 60 to drive the conical wheel 52 to move in the reverse direction of the blocking wheel 54, achieving the effect of acceleration.

[0035] In a case of this embodiment, a winding shaft 50 arranged in the front-rear direction is rotatably connected to the upper end of the tension support plate 39. A first winding wheel 47 is arranged on the side of the winding shaft 50 close to the tension support plate 39. A first traction belt 45 is wound around the outside of the first winding wheel 47. The lower end of the first traction belt 45 is connected to a pull rod 44. The pull rod 44 is fixedly connected to the outside of a slider 41. A second winding wheel 46 is arranged on the side of the winding shaft 50 far from the tension support plate 39. A second traction belt 43 is wound around the outside of the second winding wheel 46. A baffle 55 is fixedly connected to the upper end of the guide post 59. The baffle 55 is fixedly connected to the lower end of the second traction belt 43. A driven pulley 56 is rotatably connected to the outside of the counterweight sliding seat 57. The driven pulley 56 is located on the upper part of the second traction belt 43. Therefore, when the second traction belt 43 is released, the counterweight sliding seat 57 can move downward by gravity. And the diameter of the first winding wheel 47 is larger than that of the second winding wheel 46. Therefore, the up-and-down movement range of the tension roller 42 is larger than that of the counterweight sliding seat 57, avoiding that the over-large up-and-down movement distance of the tension roller 42 leads to the over-large movement distance of the conical pulley 52 and resulting in ineffective speed ratio adjustment. To ensure the stability of the winding shaft 50, an L-shaped suspension bracket 51 is arranged at the upper end of the tension support plate 39. The end of the suspension bracket 51 is rotatably connected to the winding shaft 50. To enable the counterweight sliding seat 57 to move upward in the reverse direction, a deflection arm 48 extending to the left can be arranged on the left side of the winding shaft 50. A counterweight slider 49 is slidably connected to the middle of the deflection arm 48. Seen from the front, the gravity of the counterweight slider 49 on the deflection arm 48 can make the winding shaft 50 rotate counterclockwise, and the gravity of the tension roller 42 can drive the winding shaft 50 to rotate clockwise. Thus, when the tension roller 42 moves upward, the winding shaft 50 can rotate counterclockwise, so that the first traction belt 45 and the second traction belt 43 can complete the winding process. And the counterweight slider 49 itself can offset part of the gravity of the tension roller 42. Therefore, the downward gravity brought by the tension roller 42 can be offset by adjusting the position of the counterweight slider 49 left and right, thereby achieving the effect of adjusting the tension of the aluminum strip 20.

[0036] In a case of this embodiment, a driving motor 25 is provided at the left end of the upper surface of the substrate 1. The output shaft of the driving motor 25 is connected to the middle of a transmission shaft 27 through a first transmission belt 26. The transmission shaft 27 is arranged in the front-back direction. The front and rear ends of the transmission shaft 27 are connected to a second rotating sleeve 24 through a second transmission belt 28. Therefore, the driving motor 25 can drive the second rotating sleeve 24 to rotate through a belt transmission method. And a driven gear 31 is fixedly connected to a driven rotating shaft 32, and a driving gear 30 meshed with the driven gear 31 is fixedly connected to a first rotating sleeve 29. Therefore, the first rotating sleeve 29 can drive the driven rotating shaft 32 to rotate through a gear transmission method. And the number of teeth of the driving gear 30 is less than that of the driven gear 31, so as to achieve the effect of a speed reducer, so that the driving motor 25 can drive the driven rotating shaft 32 to rotate relatively stably, that is, the driving motor 25 can drive the core shaft 23 to rotate stably at a relatively stable speed.

[0037] In a case of this embodiment, the straightening assembly 4 includes a straightening column 5 fixedly connected to the substrate 1. The straightening column 5 is vertically arranged at the front and rear ends on the upper surface of the right side of the substrate 1. A center straightening roller 6 arranged in the front and rear directions is rotatably connected to the upper part of the straightening column 5. And lifting seats 12 are slidably connected to the left and right sides of the straightening column 5. An auxiliary straightening roller 7 arranged in the front and rear directions is rotatably connected to the lifting seat 12. The auxiliary straightening roller 7 is arranged on the left and right sides of the center straightening roller 6, and the auxiliary straightening roller 7 is lower than the center straightening roller 6. The aluminum strip 20 passing through the gap between the center straightening roller 6 and the auxiliary straightening roller 7 can achieve the straightening effect. And a straightening spacing adjusting device 19 is arranged outside the straightening column 5. The straightening spacing adjusting device 19 can adjust the height difference between the auxiliary straightening roller 7 and the center straightening roller 6, so as to adjust the degree of straightening. The straightening spacing adjusting device 19 includes a top plate 13 arranged at the upper end of the straightening vertical plate. The upper parts of vertically arranged lifting lead screws 9 are rotatably connected to the front and rear ends of the top plate 13. The lower ends of the lifting lead screws 9 are rotatably connected to a fixing block 8 fixedly connected to the outside of the straightening column 5. A horizontally arranged support plate 10 is threadedly connected to the middle of the lifting lead screw 9. Guide slide bars 14 are vertically arranged on the left and right sides of the upper surface of the support plate 10. The middle parts of the guide slide bars 14 are slidably connected to the lifting seats 12. A buffer spring 11 is arranged between the lifting seat 12 and the support plate 10. By arranging the buffer spring 11, the auxiliary straightening roller 7 can slightly move up and down, avoiding the aluminum strip 20 from being stuck. Bearing blocks 17 are arranged on the front and rear sides of the upper surface of the top plate 13. A driving shaft 18 arranged in the front and rear directions is rotatably connected to the bearing blocks 17. First bevel gears 16 are fixedly connected to the front and rear sides of the driving shaft 18. The first bevel gears 16 are meshed and connected to second bevel gears 15. The second bevel gears 15 are fixedly connected to the upper ends of the lifting lead screws 9. Therefore, the driving shaft 18 makes the front and rear two lifting lead screws 9 rotate synchronously through gear transmission. The lifting lead screws 9 drive the front and rear two support plates 10 to lift synchronously, so that the front and rear ends of the auxiliary straightening roller 7 can lift synchronously, and the auxiliary straightening roller 7 can still maintain a flat state when its height is adjusted.

[0038] In a case of this embodiment, the auxiliary lifting assembly 33 includes a telescopic block 37 slidably connected to the side surface of the support side plate 21. An auxiliary support rod 35 is rotatably connected to the middle of the telescopic block 37. An auxiliary support roller 34 is fixedly connected to the end of the auxiliary support rod 35. The auxiliary support roller 34 and the active support roller 22 are at the same height. Therefore, the front and rear ends of the mandrel 23 can fall between the auxiliary support roller 34 and the active support roller 22, so that the mandrel 23 is lifted, and the mandrel 23 rotates synchronously with the active support roller 22. A push plate 36 is fixedly connected to the end of the telescopic block 37. A telescopic screw rod 38 is threadedly connected to the end of the push plate 36. The end of the telescopic screw rod 38 is rotatably connected to the side surface of the support side plate 21. The telescopic block 37 can be driven to move left and right by the telescopic screw rod 38, so as to adjust the distance between the auxiliary support roller 34 and the active support roller 22, that is, effective support and lifting treatment can be carried out on mandrels 23 with different diameters.

[0039] During the implementation of this embodiment, the empty mandrel 23 is placed on the auxiliary support roller 34 and the active support roller 22. The aluminum strip 20 to be coiled is installed from right to left. The aluminum strip 20 first passes through the gap between the auxiliary straightening roller 7 and the centering straightening roller 6, and after passing under the tension roller 42, it is wound around the outside of the mandrel 23. At this time, the installation treatment of the aluminum strip 20 is completed.

[0040] Coiling treatment: Start the driving motor 25. The driving motor 25 drives the transmission shaft 27 to rotate through belt transmission. The transmission shaft 27 drives the second rotating sleeve 24 to rotate through belt transmission. The second rotating sleeve 24 drives the first rotating sleeve 29 to rotate through the transmission belt 53. The first rotating sleeve 29 drives the driven rotating shaft 32 to rotate through gear transmission. The active support roller 22 rotates synchronously with the driven rotating shaft 32. The active support roller 22 drives the mandrel 23 to rotate. During the rotation of the mandrel 23, the aluminum strip 20 is continuously wound around the outside of the mandrel 23, thereby realizing the coiling treatment of the aluminum strip 20. During the coiling of the aluminum strip 20, the left mandrel 23 pulls the aluminum strip 20 to the left, and the right straightening assembly 4 generates resistance. At this time, the aluminum strip 20 maintains a certain tension, and the tension roller 42 is lifted by the aluminum strip 20.

[0041] When the tension of the aluminum strip 20 decreases, the upward lifting force of the aluminum strip 20 on the tension roller 42 decreases. At this time, the tension roller 42 moves downward, and the tension roller 42 drives the first winding wheel 47 to rotate by pulling the first traction belt 45. At this time, the second winding wheel 46 rotates synchronously with the first winding wheel 47, and the second winding wheel 46 releases the second traction belt 43, and the counterweight slide 57 moves downward. The counterweight slide 57 drives the guide chute 58 to move downward. The cooperation between the guide chute 58 and the limit rod 60 causes the lower conical wheel 52 to move toward the blocking wheel 54. At this time, the rotation radius below the transmission belt 53 increases, so that the angular velocity of the upper first rotating sleeve 29 increases, that is, the angular velocity of the mandrel 23 increases. At this time, the winding speed of the aluminum strip 20 increases, so that the tension of the aluminum strip 20 increases.

[0042] When the tension of the aluminum strip 20 increases, the aluminum strip 20 lifts the tension roller 42 upward at this time, and the first traction belt 45 is in a slack state. The winding shaft 50 flips under the action of the deflection arm 48. At this time, the first winding wheel 47 retracts the first traction belt 45, and the second winding wheel 46 retracts the second traction belt 43. The second traction belt 43 makes the counterweight slide 57 move upward through the driven pulley 56. At this time, the cooperation between the guide chute 58 and the limit rod 60 causes the conical wheel 52 to move away from the blocking wheel 54. At this time, the rotation radius below the transmission belt 53 decreases, so that the angular velocity of the upper first rotating sleeve 29 decreases, the rotation speed of the mandrel 23 decreases, and the curling speed of the aluminum strip 20 decreases, so that the tension of the aluminum strip 20 decreases.

[0043] In an aluminum coil winding device of the present invention, through the cooperation of the forward and backward movement of the conical wheel 52 and the up and down movement of the tension roller 42, when the tension of the aluminum strip 20 changes during the winding process, the curling speed of the aluminum strip 20 changes adaptively for adjustment, so that the aluminum strip 20 can maintain dynamic balance of tension during the winding process. The entire adjustment process only requires the cooperation of transmission components and does not require the cooperation of additional motors and sensors, so that the stability of the entire dynamic balance is better. And because the tension of the aluminum strip 20 remains dynamically stable, even if the outer diameter gradually increases during the winding process of the mandrel 23, the dynamic balance effect itself can reduce the angular velocity of the mandrel 23, so that the aluminum strip 20 remains stable during the entire winding process, thereby improving the winding effect.

[0044] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
