[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-7 As shown, a galvanized steel sheet winding device is characterized by comprising a body 1, a drive motor 2 fixedly mounted on one side of the body 1, the output end of the drive motor 2 being fixedly connected to one end of a winding roller 3, and the winding roller 3 being rotatably connected to the body 1. The winding roller 3 is an expandable structure in the prior art, facilitating unwinding. A discharge device 4 is sleeved around the winding roller 3, the rear end of the discharge device 4 being fixedly mounted on the body 1. The discharge device 4 can reciprocate along the axial direction of the winding roller 3. A pressing mechanism 5 is provided above the winding roller 3, one side of the pressing mechanism 5 being fixed to the top of the body 1, and the pressing mechanism 5 being able to move circumferentially along the winding roller 3. The unloading device 4 enables the steel coil to be smoothly unloaded from the take-up roller 3, reducing the labor intensity of workers, with a high degree of automation and improved production efficiency; the clamping mechanism 5 enables edge alignment, mainly used to prevent wrinkles, wavy edges or surface scratches from occurring on the galvanized steel sheet during the winding process, ensuring the quality of the coil; the winding device also includes a support mechanism 6, which is located at the front end of the take-up roller 3 and can reciprocate along the axial direction of the take-up roller 3. When the support mechanism 6 is working, it moves to the front end of the take-up roller 3 to support the front end of the take-up roller 3, increasing system stability and preventing the take-up roller 3 from vibrating, which would affect the quality of the steel sheet winding.

[0022] like Figure 3 As shown, the pressing mechanism 5 includes a connecting assembly 51, a lifting cylinder 52, a downward pressing arm 53, and a pressure roller 54. The lower end of the connecting assembly 51 is fixedly installed on the top of the machine body 1. One side of the upper end of the connecting assembly 51 is rotatably connected to the output end of the lifting cylinder 52, and the other side is fixedly connected to the downward pressing arm 53, which is located above the take-up shaft. The bottom of the lifting cylinder 52 is rotatably connected to the top of the machine body 1. Both ends of the pressure roller 54 are fixedly connected to the front end of the downward pressing arm 53, and the pressure roller 54 is arranged parallel to the take-up roller 3. Figure 4As shown, the connecting assembly 51 includes a first connecting member 511, a second connecting member 512, and a connecting shaft 513. The two first connecting members 511 are arranged in parallel, with the bottom of each first connecting member 511 fixedly mounted on the top of the machine body 1. The connecting shaft 513 passes sequentially through the tops of the two first connecting members 511, and is rotatably connected to each first connecting member 511. The second connecting member 512 is located between the two first connecting members 511, with one end fixedly connected to the connecting shaft 513 and the other end rotatably connected to the lifting cylinder 52. The downward-pressing swing arm 53 is fixedly connected to the connecting shaft 513. Figure 6 As shown, the pressing mechanism 5 also includes limiting members 55. Each end of the pressure roller 54 is provided with a limiting member 55, and the two limiting members 55 are arranged opposite to each other. Each limiting member 55 can be circumferentially fixed to the pressure roller 54 by multiple locking bolts. The limiting members 55 are used to limit the positions of both ends of the galvanized steel sheet and can adapt to steel sheets of different widths; Figure 5 As shown, the lowering swing arm 53 includes a lowering plate 531 and a lowering rod 532. The two lowering plates 531 are arranged in parallel. One end of the two lowering plates 531 is fixedly connected to the connecting shaft 513, and the other end of the two lowering plates 531 is fixedly connected to both ends of the pressure roller 54. A plurality of parallel lowering rods 532 are provided between the two lowering plates 531. One end of the lowering plate 531 is provided with a U-shaped opening. The two ends of the pressure roller 54 are respectively provided in the U-shaped openings of the two lowering plates 531. The outer periphery of the two ends of the pressure roller 54 is fixed to the U-shaped openings by fixing bolts.

[0023] During implementation, the galvanized steel sheet is fixed onto the take-up roller 3. The lifting cylinder 52 is activated, driving the second connecting piece 512 to move, which in turn drives the connecting shaft 513 to rotate. This, in turn, moves the lower pressure arm 53 towards the take-up roller 3, causing the two lower pressure plates 531 to move the pressure roller 54 towards the surface of the galvanized steel sheet. The positions of the two limiting pieces 55 on the pressure roller 54 are set so that each limiting piece 55 can abut against the side of the galvanized steel sheet. Multiple locking bolts are used to fix the limiting pieces 55 to the pressure roller 54. The limiting pieces 55 ensure the steel sheet remains flat during winding, guaranteeing winding quality. The limiting pieces 55 are also adjustable to accommodate galvanized steel sheets of different widths and can be disassembled and replaced, resulting in a simple structure. The drive motor 2 is then activated to rotate the take-up roller 3, which then rotates the galvanized steel sheet... The coiling process is performed by controlling the lifting cylinder 52 to control the pressure of the pressure roller 54. The roller is driven by the friction of the steel plate. The outer surface of the pressure roller 54 is covered with polyurethane to protect the galvanized layer on the steel plate surface and prevent galvanized layer loss. The position of the pressure roller 54 is adjusted in real time by controlling the lifting cylinder 52, thereby achieving real-time adjustment to ensure that the pressure of the roller surface of the pressure roller 54 is uniform with the surface of the galvanized steel plate. This ensures uniform tension of the galvanized steel plate during coiling, preventing wrinkles, wavy edges, or surface scratches on the steel plate during coiling, ensuring coil quality, improving coil tightness, making the steel coil neatly coiled, avoiding loose coiling, and improving production efficiency. The pressure roller 54 can be removed from the lower pressure plate 532 for easy replacement, reducing surface scratches and ensuring that the galvanized layer is not damaged by the roller surface of the pressure roller 54.

[0024] like Figure 7 As shown, the unloading device 4 includes an unloading plate 41 and a pushing cylinder 42. The pushing cylinder 42 is fixed on the machine body 1, and the output end of the pushing cylinder 42 is fixedly connected to the unloading plate 41. The unloading plate 41 is sleeved around the winding roller 3, and the unloading plate 41 reciprocates along the axial direction of the winding roller 3. The unloading device 4 also includes a plurality of pushing rods 43, each pushing rod 43 is arranged parallel to each other, one end of each pushing rod 43 is fixedly connected to the unloading plate 41, and the other end is slidably arranged on the machine body 1. The pushing rods 43 are used to ensure the stability of unloading.

[0025] During implementation, before winding, the unloading plate 41 is moved to one end near the machine body 1 by pushing the cylinder 42. After the galvanized steel sheet is wound, the state of the winding roller 3 is set so that the galvanized steel sheet coil can move on the winding roller 2. The pushing cylinder 42 is started to move the unloading plate 41 to the side end of the coil. The pushing cylinder 42 continues to push the unloading plate 41 to move, so that the unloading plate 41 pushes the galvanized steel sheet coil off the winding roller 3. A mobile trolley can be placed at the front end of the winding roller 3 to directly unload the coil onto the mobile trolley and then move it to the storage position. The degree of automation is high and the production efficiency is improved.

[0026] The working principle of a galvanized steel sheet coiling device is as follows: During operation, the unloading plate 41 is first moved to the end of the coiling roller 3 near the machine body 1, fixing the galvanized steel sheet onto the coiling roller 3. The coiling roller 3 is in an expanded state. The upgrading cylinder 52 is activated, causing the pressure roller 54 to move to the surface of the galvanized steel sheet. The position of the limiting member 55 is set so that the two limiting members 55 abut against the side end face of the steel sheet. The drive motor 2 is activated to drive the coiling roller 3 to rotate, coiling the galvanized steel sheet. During the coiling process, the lifting cylinder 52 is controlled in real time to adjust the position. The system ensures uniform pressure between the roller surface of the pressure roller 54 and the surface of the galvanized steel sheet. After winding, the winding roller 3 is set to a non-expanded state, and the push cylinder 42 is activated to cause the unloading plate 41 to push the galvanized steel sheet coil for unloading, thus completing one winding and unloading cycle. This process is repeated. The winding device has a high degree of automation, reduces the labor intensity of workers, and improves production efficiency. At the same time, it can control the coil shape during the winding process to ensure that the steel coil cross-section is neat, improve the coil density, make the steel coil neatly wound, avoid loose winding, and ensure the quality of the coil.
