[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a steel coil cone head, including a cylinder 1 and a tensioning mechanism 4. A piston 2 is provided inside the cylinder 1, a fixing rod 3 is provided on the outer surface of the piston 2, the tensioning mechanism 4 is provided on the outer surface of the fixing rod 3, a disc 401 is provided on the outer surface of the fixing rod 3, a slot 402 is provided on the surface of the disc 401, a sliding rod 403 is provided on the right side of the fixing rod 3, a first fixing plate 404 is provided on the outer surface of the sliding rod 403, a movable rod 405 is provided on the outer side of the first fixing plate 404, a fixing pin 406 is provided inside the movable rod 405, a second fixing plate 407 is provided on one side of the movable rod 405, a fixing plate 408 is provided at the bottom end of the second fixing plate 407, a pulley 409 is provided on the left side of the fixing plate 408, and an anti-slip pad 410 is provided on the surface of the fixing plate 408.

[0023] Furthermore, the piston 2 and the fixed rod 3 are slidably connected, and the outer diameter of the piston 2 matches the inner diameter of the fixed rod 3. With this setting, the fixed rod 3 provides the necessary support and positioning functions, avoiding problems such as friction or uneven movement caused by inaccurate fit.

[0024] Furthermore, four slots 402 are provided on the surface of the disc 401. The slots 402 are symmetrically provided on the surface of the disc 401. This arrangement allows for more flexible and precise adjustment of the tensioning mechanism 4.

[0025] Furthermore, the slide bar 403 is welded to the first fixing plate 404. Four first fixing plates 404 are welded to the surface of the slide bar 403. This arrangement avoids instability caused by loosening, helps reduce the loosening of parts, and extends the service life.

[0026] Furthermore, the first fixing plate 404 forms a movable structure with the movable rod 405 via the fixing pin 406, and the second fixing plate 407 forms a movable structure with the movable rod 405 via the fixing pin 406. With this arrangement, an adjustable tension movable structure is formed, which can adjust the tension according to the inner diameter of the roll material, so as to achieve the best effect under different inner diameter sizes.

[0027] Furthermore, the second fixing piece 407 is welded to the fixing plate 408, and the second fixing piece 407 and the fixing plate 408 correspond one-to-one. This arrangement ensures that the second fixing piece 407 and the fixing plate 408 are firmly fixed, avoiding relative movement caused by vibration or external force during operation, and ensuring the stability and reliability of the tensioning mechanism 4.

[0028] Furthermore, the second fixing plate 407 and the pulley 409 are connected by screws, and the second fixing plate 407 and the pulley 409 correspond one-to-one. With this setting, the pulley 409 is installed on the left side of the second fixing plate 407 and is in close contact with the surface of the disc 401, which makes the tensioning movement smoother and avoids jamming.

[0029] Furthermore, the fixing plate 408 and the anti-slip pad 410 are bonded together, and the fixing plate 408 and the anti-slip pad 410 are tightly attached. This arrangement increases the friction between the fixing plate 408 and the inner hole of the coil material, thus preventing slippage.

[0030] Working principle: First, the coiled material is fed to the right side near the disc 401. Then, the piston 2 is retracted by the cylinder 1. A sliding rod 403 is fixedly connected to the end of the piston 2. The sliding rod 403 slides to the left on the outer surface of the fixed rod 3. The sliding rod 403 drives the first fixed plate 404 to move. During the movement, the fixing pin 406 rotates within the first fixed plate 404, driving the movable rod 405. The other side of the movable rod 405 is rotatably connected to the second fixed plate 407 through the fixing pin 406. The second fixed plate 407 is welded to the fixing plate 408. The fixing plate 408 is slidably connected to the slot 402. The two fixing plates 407, driven by the sliding rod 403, the first fixing plate 404, the movable rod 405, and the fixing pin 406, cause the fixing plate 408 to move in and out, so that the four fixing plates 408 can perform tensioning movement within the groove path of the slot 402, firmly fixing the inner hole of the coil. The pulley 409 is installed on the left side of the second fixing plate 407 and is in close contact with the surface of the disc 401, making the tensioning movement smoother and avoiding jamming. The anti-slip rubber pad 410 increases the friction between the fixing plate 408 and the inner hole of the coil, preventing slippage. This completes the use process of a steel coil cone head.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
