Description

Technical Field

[0001] This utility model belongs to the technical field of strip steel winding equipment, specifically relating to a strip steel winding device with an adjustable diameter structure. Background Technology

[0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Strip steel winding equipment is an indispensable piece of equipment in the production, processing, and application of strip steel.

[0003] A strip steel winding device is used to wind strip steel into coils, and is widely used in industries such as steel, automobiles, and home appliances. Its principle is that the strip steel is unwound from the uncoiler, guided by a guiding device, and enters the winding mechanism. The drive system rotates the take-up roller, and under the friction between the take-up roller and the strip steel, the strip steel is gradually wound onto the take-up roller. The tension control system monitors and adjusts the tension of the strip steel in real time to ensure that the tension of the strip steel remains within the set range during the winding process. The guiding device ensures that the strip steel moves in the correct direction during the winding process, avoiding deviation. When a certain length or a set coil weight is reached, the shearing device cuts the strip steel, completing one winding process. Then, the unloading device unloads the coiled steel coil for subsequent processing.

[0004] During the unwinding and release process of strip steel coils, the inner diameter of the strip steel coil varies, and when the strip steel coil is placed on the winding device for unwinding, the take-up rollers of the winding device are usually not compatible with the inner diameter of the strip steel coil. During the unwinding and release process, the strip steel coil rotates with the take-up rollers, and the state of the strip steel coil is unstable during rotation, which can easily damage the strip steel winding device.

[0005] To address this problem, this invention aims to provide a strip winding device with an adjustable diameter structure. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] A strip winding device with an adjustable diameter structure includes a main unit 1. The main unit 1 is the body of a conventional hydraulic uncoiler, and a rotating head 2 is provided at the main unit 1, which drives the rotating head 2 to rotate. The rotating head 2 includes a main drive seat 3 and an adjusting threaded rod 4, both of which are connected to the main unit 1, with the adjusting threaded rod 4 passing through the main drive seat 3. The main drive seat 3 and the adjusting threaded rod 4 operate relatively independently, enabling them to rotate independently or synchronously.

[0028] A threaded seat 5 is provided on the adjusting threaded rod 4, and the two are connected by a threaded connection. The position of the threaded seat 5 on the adjusting threaded rod 4 can be adjusted by relative rotation. Four long grooves 6 are provided on the outer wall of the threaded seat 5, evenly distributed in a circular array. Two connecting rods 7 are hinged in each long groove 6. A spreading plate 8 is hinged to the end of each of the two connecting rods 7. A track plate 9 is provided at the main drive seat 3, and four spreading plate tracks 10 are provided on the track plate 9, evenly distributed in a circular array. One end of the spreading plate 8 is T-shaped, allowing it to embed into the spreading plate track 10 and move along it. When the main drive seat 3 is stationary, the threaded seat 5 cannot rotate due to the constraint of the spreading plate 8. When the adjusting threaded rod 4 rotates, the threaded seat 5 begins to move along the adjusting threaded rod 4. During this movement, the threaded seat 5 can cause the spreading plate 8 to converge or disperse.

[0029] An L-shaped baffle 11 is provided on the outer wall of the expansion plate 8. The L-shaped baffle 11 includes an A arm 12 and a B arm 13. An adjusting rail 14 is provided at the A arm 12, and an adjusting screw 15 is provided on the outer wall of the expansion plate 8, passing through the adjusting rail 14. This design allows for adjustment of the position of the L-shaped baffle 11. A circular baffle 16 is provided at the outermost position of the threaded seat 5, and an adjusting threaded rod 4 passes through the circular baffle 16. A through hole 17 is provided at the center of the circular baffle 16, and the adjusting threaded rod 4 passes through the through hole 17. Four positioning blocks 18 are provided at the edge of the through hole 17, and the four positioning blocks 18 are embedded in the four elongated slots 6 one-to-one. A fixing nut 19 is provided at the adjusting threaded rod 4. After the circular baffle 16 is closed, the fixing nut 19 is tightened inward so that the circular baffle 16 is tightly attached to the threaded seat 5. Four pre-drilled holes 20 for the support plate are provided at the circular baffle 16. The four pre-drilled holes 20 for the support plate are evenly distributed in a ring array at the circular baffle 16. The four pre-drilled holes 20 for the support rod groove are set one-to-one with the four support plates 8.

[0030] During use, the main drive seat 3 does not rotate, while the adjusting threaded rod 4 rotates to adjust the opening of the spreading plate 8 to fit the inner diameter of the steel coil. After adjustment, the position of the L-shaped baffle 11 is adjusted. After adjustment, the steel coil is hoisted for installation. Next, the circular baffle 16 is installed. The L-shaped baffle 11 and the circular baffle 16 can precisely clamp the steel coil. Finally, the opening of the spreading plate 8 is finely adjusted so that the four spreading plates 8 fully press against the inner diameter of the steel coil.

[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.
