AI Technical Summary
During operation, the winding device of the existing cold rolling mill has many gaps between each layer of the coil, resulting in a loose coil structure. When stored, the coil is prone to elliptic deformation due to its own weight, which damages the internal structure of the material.
The device employs an internal clamping structure and a pressing assembly. The internal clamping structure uses components such as guide rods, threaded rods, and crank handles to achieve rapid clamping and release of the winding drum. The pressing assembly applies downward pressure to the roll material through pressure rollers and tension springs, reducing the gap between each layer of the roll material and improving compactness.
It enables rapid clamping and release of take-up drums of different sizes, reduces the gap between roll layers, improves roll compactness, prevents elliptic deformation, and enhances the structural stability of the material.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0020] Please see Figure 1-3 This utility model provides a technical solution: a winding device for a reversible cold rolling mill, including an L-shaped bracket 1, a rotating shaft A2 rotatably mounted on the L-shaped bracket 1, a hollow roller 3 fixedly mounted on one end of the rotating shaft A2, a winding drum 4 arranged on the outer side of the hollow roller 3, a roll of material 5 wound on the outer wall of the winding drum 4, a fixing frame 14 fixedly mounted on the top of the L-shaped bracket 1, an inner clamping structure mounted on the hollow roller 3 for fixing the winding drum 4 to the outer side of the hollow roller 3, a driving structure mounted on the L-shaped bracket 1 and the rotating shaft A2 for driving the hollow roller 3 to rotate at a uniform speed, and a pressing component mounted on the top of the roll of material 5 for pressing the roll of material 5.
[0021] Furthermore, the internal clamping structure includes a guide rod 6, a threaded rod 7, a crank handle 8, a push block A9, a movable rod 10, a push block B11, and a push rod 12. The guide rod 6 is fixedly installed on the front and rear inner walls of the hollow roller 3. The threaded rod 7 is rotatably installed on the front and rear sides of the hollow roller 3. The crank handle 8 is fixedly installed on one end of the threaded rod 7. The push block A9 is slidably installed on the guide rod 6 and threadedly installed on the threaded rod 7. The movable rod 10 is slidably installed on the hollow roller 3. The push block B11 is fixedly installed on the bottom end of the movable rod 10. Push rod 12 is fixedly installed on the top of movable rod 10. Manually twisting handle 8 drives threaded rod 7 to rotate. The rotation of threaded rod 7 drives push block A9 to move forward. When push block A9 moves forward, push block A9 pushes the two push blocks B11, movable rod 10 and push rod 12 upward and downward respectively, driving the two push rods 12 to push the top and bottom of take-up drum 4, fixing take-up drum 4 to the outside of hollow roller 3. It can be compatible with most sizes of take-up drum 4, improving the applicability of the take-up device.
[0022] Furthermore, the drive structure includes a motor 15, a rotating shaft B16, a synchronous pulley A17, a synchronous pulley B18, and a synchronous belt 19. The motor 15 is fixedly installed on the top of the fixed frame 14, the rotating shaft B16 is rotatably installed on the L-shaped bracket 1, the synchronous pulley A17 is fixedly installed on the outer wall of the rotating shaft B16, the synchronous pulley B18 is fixedly installed on the outer wall of the rotating shaft A2, and the synchronous belt 19 is sleeved on the synchronous pulleys B18 and A17. The synchronous belt 19 meshes with the synchronous pulleys A17 and B18. The output shaft of the motor 15 is fixedly installed at one end of the rotating shaft B16. When the motor 15 is started, the output shaft of the motor 15 drives the rotating shaft B16 and the synchronous pulley A17 to rotate. The synchronous pulley A17 drives the synchronous pulley B18, the rotating shaft A2, the hollow roller 3, and the winding drum 4 to rotate through the synchronous belt 19. The rotation of the winding drum 4 winds up the roll material 5.
[0023] Furthermore, the pressing assembly includes a pressure roller 20, a fixing rod 21, a T-shaped frame 22, and a tension spring 23. The pressure roller 20 is rotatably mounted on the outer wall of the T-shaped frame 22, the fixing rod 21 is fixedly mounted on the L-shaped bracket 1, and the T-shaped frame 22 is rotatably mounted on the outer wall of the fixing rod 21. The outer wall of the pressure roller 20 is in contact with the top of the roll material 5. The tension spring 23 is fixedly mounted on the top of the fixing frame 14 and the bottom of the T-shaped frame 22. When the roll material 5 is wound up, the tension spring 23 pulls the T-shaped frame 22 and the pressure roller 20 downward, causing the pressure roller 20 to press the roll material 5, reducing the gaps between each layer of the roll material 5 and improving the compactness of the roll material 5.
[0024] Furthermore, an electric lifting rod 24 is fixedly installed on the L-shaped bracket 1 and the fixed frame 14. A wheel frame 25 is fixedly installed on the free end of the electric lifting rod 24. Rollers 26 are rotatably installed on the front and rear sides of the wheel frame 25. After the roll material 5 is wound up, the electric lifting rod 24 is activated. The free end of the electric lifting rod 24 pushes the wheel frame 25 and rollers 26 upward. The upward movement of the rollers 26 pushes the T-shaped rod frame 22 and pressure roller 20 upward, causing the pressure roller 20 to separate from the roll material 5, thereby enabling the winding drum 4 and the roll material 5 to be removed from the outside of the hollow roller 3.
[0025] Furthermore, a return spring 13 is sleeved on the outer wall of the movable rod 10. The return spring 13 is fixedly installed on the inner wall of the hollow roller 3 and the top of the push block B11, and is used to reset the push block B11, the movable rod 10, and the push rod 12.
[0026] Working principle: The take-up drum 4 is sleeved on the outside of the hollow roller 3. By manually turning the crank handle 8, the crank handle 8 drives the threaded rod 7 to rotate. The rotation of the threaded rod 7 drives the push block A9 to move forward. When the push block A9 moves forward, it pushes the two push blocks B11, the movable rod 10, and the push rod 12 upward and downward respectively, driving the two push rods 12 to press the top and bottom of the take-up drum 4, fixing the take-up drum 4 on the outside of the hollow roller 3. The motor 15 is started by the remote control. The output shaft of the motor 15 drives the rotating shaft B16 and the synchronous pulley A17 to rotate. The synchronous pulley A17 drives the synchronous pulley B1 through the synchronous belt 19. 8. The rotating shaft A2, hollow roller 3, and take-up drum 4 rotate. The rotation of the take-up drum 4 winds up the roll material 5. When the roll material 5 is wound up, the tension spring 23 pulls the T-shaped rod 22 and pressure roller 20 downward, causing the pressure roller 20 to press the roll material 5 and tighten the wound roll material 5. After the roll material 5 is wound up, the electric lifting rod 24 is activated. The free end of the electric lifting rod 24 pushes the wheel frame 25 and roller 26 upward. The upward movement of the roller 26 pushes the T-shaped rod 22 and pressure roller 20 upward, causing the pressure roller 20 to separate from the roll material 5, thereby allowing the take-up drum 4 and the roll material 5 to be removed from the outside of the hollow roller 3.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
