DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0021] like Figure 1-4As shown, the utility model provides a winding device for packaging film for photovoltaic modules, including a fixed plate 1, two vertical blocks 2 are fixedly connected to the fixed plate 1, and the two vertical blocks 2 are rotatably connected to a rotating column 4 through a T-shaped rotating ring 3. The interior of the two rotating columns 4 is threadedly connected to a threaded rod 5, and one end of the two threaded rods 5 is fixedly connected to a connecting rotating block 6. The adjacent sides of the two connecting rotating blocks 6 are clamped and fixedly connected to a winding roller 8 through an installation groove 7. The outside of the two threaded rods 5 is provided with a spring 9, and one end of the spring 9 is fixedly connected to one side of the rotating column 4. The other end is fixedly connected to the connecting ring block 10, and a T-slot 11 is opened on one side of the connecting ring block 10. The inner annular sliding connection of the T-slot 11 is connected to a T-ring block 12, and one side of the second T-ring block 12 is fixedly connected to one side of the connecting rotating block 6. By rotating the connecting rotating block 6, when the connecting rotating block 6 rotates, the threaded rod 5 is driven to rotate. The threaded rod 5 is rotated in the rotating column 4 through the thread, thereby driving the mounting groove 7 to gradually move away from one end of the winding roller 8, thereby releasing the clamping of the winding roller 8. When installation is required, first align the two ends of the winding roller 8 with the installation grooves 7 on the connecting rotary block 6, and then rotate the connecting rotary block 6. The rotation of the connecting rotary block 6 will drive the threaded rod 5 to rotate, and the threaded rod 5 will be displaced and extended by rotation, thereby driving the two connecting rotary blocks 6 to displace until the two connecting rotary blocks 6 clamp the two ends of the new winding roller 8. During this period, the connecting rotary block 6 will drive the connecting ring block 10 to displace through the T-ring block 12 during the clamping displacement, and the connecting ring block 10 will drive the spring 9 to rebound, and the rebound of the spring 9 will limit the rotation of the connecting rotary block 6. During this period, the winding roller 8 can be replaced and installed by rotation, which is more convenient, thereby helping to save a certain amount of manpower and improve work efficiency.

[0022] To further explain, a fixing block 13 is fixedly connected to the fixing plate 1 .

[0023] To further explain, a driving motor 14 is fixedly connected to the upper surface of the fixing block 13 .

[0024] To further explain, the output shaft of the driving motor 14 is fixedly connected to the first transmission wheel 15 , and one side of the rotating column 4 is fixedly connected to the second transmission wheel 16 .

[0025] To further explain, the diameter of the first transmission wheel 15 is smaller than the diameter of the second transmission wheel 16 .

[0026] To further explain, a transmission belt 17 is provided between the first transmission wheel 15 and the second transmission wheel 16. By setting the drive motor 14, the first transmission wheel 15 can be driven to rotate under the power output of the drive motor 14. The first transmission wheel 15 drives the second transmission wheel 16 to rotate through the transmission belt 17. The second transmission wheel 16 drives the rotating column 4 to rotate. The rotating column 4 drives the connecting rotating block 6 to rotate through the threaded rod 5. The connecting rotating block 6 drives the winding rotation of the clamped winding roller 8. During this period, the diameter of the first transmission wheel 15 is smaller than that of the second transmission wheel 16, which can make the winding of the winding roller 8 more labor-saving, which helps to ensure the stability of the winding.

[0027] The working principle and usage process of the present invention are as follows: when disassembly is required, by rotating the connecting turn block 6, the threaded rod 5 will be driven to rotate when the connecting turn block 6 rotates. The threaded rod 5 is rotated in the rotating column 4 through the thread, and then the mounting groove 7 is driven to gradually move away from one end of the winding roller 8, thereby releasing the clamping and fixation of the winding roller 8. When installation is required, the two ends of the winding roller 8 are aligned with the mounting groove 7 on the connecting turn block 6, and then the connecting turn block 6 is rotated. The rotation of the connecting turn block 6 will drive the threaded rod 5 to rotate, and the threaded rod 5 is displaced and extended by rotation, thereby driving the two connecting turn blocks 6 to displace until the two connecting turn blocks 6 clamp the two ends of the new winding roller 8.

[0028] It will be easily understood by those skilled in the art that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
