Description

[0001] This application claims priority to the earlier application filed on May 30, 2025, with application number 2025211001105. Technical Field

[0002] This utility model relates to the field of winding machine technology, and in particular to a winding machine based on hot-rolled composite coil. Background Technology

[0003] After production, hot-rolled composite coils need to be neatly wound by winding equipment for storage and transportation. However, most winding machines cannot assist in pressing the wound composite coils, resulting in insufficient tightness during winding. This can easily lead to loosening of the composite coils during winding, affecting the tightness of the coil winding. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] Based on a hot-rolled composite coil winding machine, including:

[0006] A mounting bracket, wherein a mounting groove is provided on one side of the top of the mounting bracket;

[0007] The clamping assembly includes a bracket fixedly mounted on the mounting groove, a connecting frame rotatably mounted on the bracket, two sets of hollow rotating shafts symmetrically rotatably mounted at the ends of the connecting frame, and a pressing roller fixedly mounted between the two sets of rotating shafts. One set of rotating shafts is connected to an expansion tube, and an air inlet pipe is rotatably inserted into the end of the expansion tube away from the rotating shaft. Multiple sets of elastic seals are provided inside the expansion tube to seal the air inlet pipe port.

[0008] The take-up roller is rotatably mounted on a fixed frame and is parallel to the axis of the press roller;

[0009] During the winding process of the composite roll, the external force drives the connecting frame to rotate around the connection between the support and the connecting frame, controlling the pressing roller to maintain rolling pressure throughout the entire winding process of the composite roll. When the pressing roller rotates, under the action of centrifugal force, the elastic seal opens, allowing the gas inside the air inlet pipe to enter the cavity of the pressing roller.

[0010] As an improvement to the above technical solution, another set of the rotating shafts has an air outlet pipe rotatably inserted at its end, and a pressure relief valve is installed on the air outlet pipe.

[0011] As an improvement to the above technical solution, the elastic seal includes a spring arranged radially along the inner wall of the expansion tube and a sealing plate arranged at the end of the spring away from the expansion tube, and multiple sets of the sealing plates seal the opening of the air inlet pipe.

[0012] As an improvement to the above technical solution, it also includes a hydraulic rod rotatably mounted on the mounting groove, the hydraulic rod being rotatably connected to the connecting frame.

[0013] The beneficial effects of this utility model are:

[0014] By driving the connecting frame and pressing rollers with external force, the mechanism responds to changes in the roll diameter and maintains rolling pressure throughout the winding process. This effectively prevents the roll from springing open or loosening due to changes in roll diameter, ensuring the tightness and regularity of the winding.

[0015] The centrifugal force generated by the rotation of the pressing roller is used to automatically control the ventilation, so that cold air enters the pressing roller cavity through the air inlet pipe and quickly removes the heat generated by the contact and friction of the high-temperature roll material. This achieves "rotation to open, stillness to close" air control and avoids the problem of the roll material deforming due to heat. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be 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 illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Based on a hot-rolled composite coil winding machine, including:

[0022] The fixing frame 10 has a mounting groove 11 on one side of its top.

[0023] The pressing assembly includes a bracket 20 fixedly mounted on the mounting groove 11, a connecting frame 22 rotatably mounted on the bracket 20, two sets of hollow rotating shafts 24 symmetrically rotatably mounted at the ends of the connecting frame 22, and a pressing roller 23 fixedly mounted between the two sets of rotating shafts 24. One set of rotating shafts 24 is connected to an expansion tube 241. An air inlet pipe 27 is rotatably inserted into one end of the expansion tube 241 away from the rotating shaft 24. Multiple sets of elastic seals are provided inside the expansion tube 241 to seal the port of the air inlet pipe 27.

[0024] The take-up roller 30 is rotatably mounted on the fixed frame 10 and is parallel to the axis of the pressing roller 23;

[0025] During the winding process of the take-up roller 30, the connecting frame 22 is driven by external force to rotate around the connection between the support 20 and the connecting frame 22, thereby controlling the pressing roller 23 to maintain rolling pressure throughout the entire winding process of the composite roll. When the pressing roller 23 rotates, under the action of centrifugal force, the elastic seal is opened, allowing the gas inside the air inlet pipe 27 to enter the cavity of the pressing roller 23.

[0026] Specifically, in the initial stage, due to the small diameter of the roll material, the connecting frame 22 is driven by external force to rotate around the support 20, causing the pressing roller 23 to press downwards against the surface of the roll material. As the roll material is continuously wound up and the diameter gradually increases, the connecting frame 22 is driven by external force to rotate and rise accordingly, driving the pressing roller 23 to move upwards, always maintaining its contact with the surface of the roll material, thereby ensuring continuous pressing throughout the winding process and preventing it from springing open and loosening. The internal cavity of the pressing roller 23 is connected to the cold air source through the air inlet pipe 27. When the pressing roller 23 rotates with the roll material, the hollow rotating shaft 24 drives the expansion tube 241 to rotate synchronously. Centrifugal force causes the elastic seal to overcome the elastic force and open outwards. The air inlet pipe 27 is connected to the expansion tube 241, and external gas passes through it. The air inlet pipe 27 enters the cavity of the pressing roller 23, cooling the pressing roller 23 and effectively reducing the heat generated by friction when the pressing roller 23 comes into contact with the high-temperature composite coil, preventing the coil from deforming due to heat. When the speed of the pressing roller decreases or stops, the centrifugal force decreases, and the elastic seal resets under the action of elasticity, re-sealing the air inlet pipe 27 and stopping the air supply. This achieves an adaptive air control effect of rotation triggering and static closure. During the winding process, the pressing roller 23 provides continuous pressing force through mechanical contact and achieves self-cooling through the centrifugal ventilation mechanism triggered by rotation. The synergistic effect of the two ensures that the hot-rolled composite coil is tightly bonded and not easy to loosen during winding, while avoiding the deterioration of material properties caused by high temperature, thus improving the winding quality and stability.

[0027] In one embodiment, an air outlet pipe 28 is rotatably inserted into the end of another set of rotating shafts 24. A pressure relief valve is installed on the air outlet pipe 28. When the pressure inside the cavity exceeds the threshold, the pressure relief valve automatically opens to discharge excess gas, thereby achieving gas replacement in the cavity 231, improving heat exchange efficiency, and allowing cold air to fill the cavity 231 of the pressing roller 23.

[0028] In one embodiment, the elastic seal includes a spring 25 radially disposed on the inner wall of the expansion tube 241 and a sealing plate 26 disposed at the end of the spring 25 away from the expansion tube 241. Multiple sets of sealing plates 26 block the opening of the air inlet pipe 27. When the pressing roller 23 is stationary, the spring 25 is in a naturally extended state, pushing the sealing plate 26 to move toward the port of the air inlet pipe 27. Multiple sets of sealing plates 26 fit tightly together to form a sealing surface, blocking the flow of gas. When the pressing roller 23 rotates, as the sealing plates 26 move, gaps appear between the sealing plates 26, causing the opening of the air inlet pipe 27 to open, and the air inlet pipe 27 to communicate with the interior of the expansion tube 241, allowing cold air to enter the cavity 231 of the pressing roller 23.

[0029] In one embodiment, a hydraulic rod 21 is rotatably mounted on the mounting groove 11. The hydraulic rod 21 is rotatably connected to the connecting frame 22. The piston rod of the hydraulic rod 21 extends out and pushes the connecting frame 22 to rotate around the connection point, so that the pressing roller 23 presses the roll material downward. During the process of increasing the roll diameter, the piston rod of the hydraulic rod 21 is synchronously driven to retract, so as to keep the pressing roller 23 in contact with the surface of the roll material.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
