Description

Technical Field

[0001] This utility model belongs to the technical field of winding and unwinding devices, and specifically relates to a winding and unwinding device for steel coils used in factory exterior wall insulation boards. Background Technology

[0002] Factory exterior wall insulation boards mostly adopt a composite structure of "steel plates on both sides + insulation layer in the middle". The steel plates on both sides need to be processed into shape through processes such as uncoiling and cutting of steel coils. The stable uncoiling of steel coils directly determines the processing accuracy of steel plates and the overall quality of insulation boards.

[0003] There are three key points to note when uncoiling steel coils: First, steel coils typically weigh several tons. Without a support mechanism, the uncoiling shaft is prone to bending and deformation due to overload, causing the steel coil to rotate eccentrically. This results in large deviations in the flatness of the processed steel plate, which can easily lead to gaps when it is laminated with the insulation layer, affecting the insulation performance. Second, during the uncoiling process, the layers of the steel coil are prone to slippage and bursting due to tension fluctuations, which can easily cause wrinkles in the steel plate. Third, the diameter of the steel coil gradually decreases as it is uncoiled, making it prone to lateral movement due to the shift in the center of gravity. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a steel coil winding and unwinding device for factory exterior wall insulation boards, so as to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A steel coil unwinding device for exterior wall insulation panels in factories includes an unwinding motor and an expansion shaft. The expansion shaft is mounted on the output shaft of the unwinding motor. A transfer assembly for conveying the steel coil is installed at the bottom end of the expansion shaft. Correction plates are installed on both sides of the expansion shaft. A support tail seat for rotating and supporting the expansion shaft is installed on the side of the expansion shaft away from the unwinding motor. An anti-loosening component is installed on the transfer assembly.

[0007] Preferably, the correction plate includes a fixed plate and a movable plate, and multiple sets of correction strips are installed on the opposite surfaces of the fixed plate and the movable plate. The correction strips extend along the radial direction of the fixed plate and the movable plate, and the steel coil contacts the correction strips.

[0008] Preferably, the movable plate is semi-circular and mounted on the output end of the support tailstock.

[0009] Preferably, the support tailstock includes a mounting base, on which a rotating arm is rotatably mounted, and on which a support shaft seat is mounted, wherein when the support shaft seat rotates to a horizontal position, it contacts and rotates relative to the central axis of the expansion shaft.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example 1

[0023] refer to Figures 1 to 4 The steel coil unwinding device for factory exterior wall insulation panels described in this embodiment includes an unwinding motor 1 and an expansion shaft 2. The expansion shaft 2 is installed on the output shaft of the unwinding motor 1. A transfer assembly 5 for conveying the steel coil is installed at the bottom end of the expansion shaft 2. Correction plates 3 are installed on both sides of the expansion shaft 2. A support tail seat 4 for rotating and supporting the expansion shaft 2 is installed on the side of the expansion shaft 2 away from the unwinding motor 1. An anti-loosening assembly 6 is installed on the transfer assembly 5.

[0024] The transfer assembly 5 includes a track 51 and a transfer trolley. The transfer trolley includes a base 52 with wheels, a lifting frame 53 mounted on the base 52, and a support platform 54 for supporting the steel coil mounted on the lifting frame 53. The top of the support platform 54 is arc-shaped. The steel coil is placed on the support platform 54 and transferred along the track 51 to the expansion shaft 2. After the expansion shaft 2 expands and supports the steel coil, the lifting frame 53 drives the support platform 54 to descend.

[0025] Preferably, the lifting frame 53 is an X-shaped lifting frame, which includes two sets of first support plates 531 and two sets of second support plates 532. The first support plates 531 and the second support plates 532 are intersected and rotatably connected. The top end of the first support plate 531 is slidably connected to the support platform 54, and the bottom end of the first support plate 531 is rotatably connected to the base 52. The top end of the second support plate 532 is rotatably connected to the support platform 54, and the bottom end is rotatably connected to a sliding mounting block 57. The sliding mounting block 57 is slidably connected to the base 52. A connecting rod 535 is installed between the two sets of sliding mounting blocks 57. A connecting block 536 is installed on the connecting rod 535. A drive motor 533 is installed on the base 52. A lead screw 534 is rotatably installed on the base 52. The lead screw 534 is fixedly connected to the output shaft of the drive motor 533. The lead screw 534 is threadedly connected to the connecting block 536. The drive motor 533 drives the lead screw 534 to rotate, thereby driving the connecting block 536 to move along the lead screw 534. The connecting block 536 drives the sliding mounting block 537 to move through the connecting rod 535, thereby driving the ends of the first support plate 531 and the second support plate 532 to move closer or further apart, thereby realizing the lifting and lowering of the drive support platform 54.

[0026] The anti-loosening component 6 includes a receiving groove 61 with its opening facing upward on the support platform 54. A pressure roller 62 is installed in the receiving groove 61 via an elastic element 63. The pressure roller 62 rotates relative to the steel coil in contact with it. The elastic element 63 includes a compression spring. When the lifting frame 53 descends, the deformation of the elastic element 63 decreases.

[0027] Preferably, there are four sets of elastic elements 63 and two sets of pressure rollers 62. Each end of the pressure roller 62 is rotatably mounted with a set of mounting blocks 64. The two ends of the elastic elements 63 are fixedly connected to the mounting blocks 64 and the inner wall of the bottom end of the receiving groove 61, respectively.

[0028] Preferably, a guide rod 65 is installed at the bottom end of the pressure roller 62, and the bottom end of the guide rod 65 passes through the support platform 54 and is slidably connected to the support platform 54.

[0029] The correction plate 3 includes a fixed plate 31 and a movable plate 32. Multiple sets of correction strips 33 are installed on the opposite surfaces of the fixed plate 31 and the movable plate 32. The correction strips 33 extend along the radial direction of the fixed plate 31 and the movable plate 32. The steel coil contacts the correction strips 33. If there is a gap between the correction plate 3 and the steel coil, the steel coil will still tend to deviate during rotation. When the correction plate 3 and the steel coil are in complete contact, excessive friction may affect unwinding. By setting the correction strips 33, the contact area between the correction plate 3 and the steel coil is greatly reduced, ensuring both the correction effect and the efficiency of unwinding.

[0030] The support tailstock 4 includes a mounting base 42, on which a rotating arm 43 is rotatably mounted, and a support shaft seat 45 is mounted on the rotating arm 43. When the support shaft seat 45 rotates to a horizontal position, it contacts the central axis of the expansion shaft 2 and rotates relative to it.

[0031] Specifically, a cylinder 41 is mounted on the mounting base 42, and an active arm 44 is rotatably mounted on the rotating arm 43. The active arm 44 is rotatably connected to the output shaft of the cylinder 41. The cylinder 41 drives the active arm 44 to push the rotating arm 43 to rotate. After the steel coil is installed, the rotating arm 43 drives the support shaft seat 45 to rotate to a horizontal state to support the rotating shaft of the expansion shaft 2 and balance the center of gravity.

[0032] The movable plate 32 is fixedly connected to the rotating arm 43. The movable plate 32 is semi-circular. The inner diameter of the movable plate 32 is larger than the radius of the central axis of the expansion shaft 2. When the support shaft seat 45 supports the central axis of the expansion shaft 2, the straight edge of the movable plate 32 remains horizontal.

[0033] Working principle: The steel coil is placed on the support platform 54, and then the base 52 slides the steel coil onto the expansion shaft 2 along the track 51. The cylinder 41 is activated and drives the rotating arm 43 to rotate through the active arm 44 until the support shaft seat 45 abuts against the central axis of the expansion shaft 2. At the same time, the movable plate 32 is moved to one side of the steel coil under the drive of the rotating arm 43. The correction strips 33 on the movable plate 32 and the fixed plate 31 are in contact with the steel coil. The lifting frame 53 drives the support platform 54 to descend, and the pressure roller 62 abuts against the outer ring of the steel coil under the push of the elastic element 63 to prevent the steel coil tension from becoming loose. When the unwinding motor 1 drives the expansion shaft 2 to rotate and unwind, the contact area between the correction strips 33 and the steel coil is small, ensuring that the steel coil is unwound smoothly while ensuring the correction effect. The pressure roller 62 is always in contact with the outer ring of the steel coil under the push of the elastic element 63 to reduce loosening caused by tension. Since the steel coil is heavy, the support shaft seat 45 supports the expansion shaft 2 to ensure the stability of the center of gravity. Stable unwinding of steel coils allows for the production of high-quality steel sheets for insulation boards.
