[0009] By adopting the above technical scheme, the setting of the unwinding sleeve enables the user to select appropriate size and number of unwinding sleeves according to the inner diameter of different steel belt rolls, and after the user sequentially nests these unwinding sleeves on the unwinding inner shaft, the corresponding steel belt roll can be tightly sleeved on the outer ring wall of the unwinding sleeve farthest from the unwinding inner shaft, thereby enabling the unwinding shaft to adapt to steel belt rolls of multiple specifications.

[0013] By adopting the above technical scheme, the setting of the winding sleeve enables the user to select appropriate size and number of winding sleeves according to the inner diameter of different steel belt rolls, and after the user sequentially nests these winding sleeves on the winding inner shaft, the corresponding steel belt roll can be tightly sleeved on the outer ring wall of the winding sleeve farthest from the winding inner shaft, thereby enabling the winding shaft to adapt to steel belt rolls of multiple specifications.

[0015] By adopting the technical scheme, the winding pressure plate can be screwed with the winding screw hole and abut the steel strip coil between the winding disc and the winding pressure plate, so that the steel strip coil is not prone to up and down deviation during winding.

[0016] Specifically, the driving assembly comprises a driving motor and a belt, the bottom of the unwinding disc is provided with a disc shaft along the middle axis thereof, the bottom of the winding disc is provided with a winding shaft along the middle axis thereof, the disc shaft and the winding shaft extend through the through hole formed in the top surface of the processing table to the lower portion of the processing table, and the output shaft of the driving motor is in transmission connection with the disc shaft and the winding shaft through the belt.

Then, they can glue one end of the two small coils together using tape, glue, or other methods. Then, the process can begin... The drive assembly drives the unwinding and rewinding reels to rotate in the same direction, so that the small coils of steel strip on the unwinding shaft can be wound onto the small coils of steel strip on the rewinding shaft. After the small coils of steel strip on the unwinding shaft are unwound, the user can replace the small coils of steel strip on the unwinding shaft and repeat the above operation. After repeating this process several times, the user can use the semi-automatic small coil rewinding machine to combine multiple small coils of steel strip into a large coil of steel strip.

[0028] Figure 1 This is a perspective view of the semi-automatic rewinding machine for small coil steel strips described in this application. Figure 2 It is along Figure 1 A schematic cross-sectional view taken along the centerline of the reel. See also Figure 1 and Figure 2The semi-automatic strip rewinding machine for small coils provided in this application includes: a processing table 1, an unwinding reel 2, an unwinding shaft, a take-up reel 3, a take-up shaft, and a drive assembly 4. The processing table 1 has a pair of circular slots, with the unwinding reel 2 and take-up reel 3 corresponding to each of the two slots. The unwinding reel 2 and take-up reel 3 are respectively positioned in their respective circular slots, and the top surfaces of both the unwinding reel 2 and take-up reel 3 are flush with the top surface of the processing table 1. The unwinding shaft includes an inner unwinding shaft 21, an unwinding pressure plate 23, and two unwinding collars 22. The top of the unwinding reel 2 has an unwinding screw hole along its central axis. The bottom end of the inner unwinding shaft 21 has an external thread adapted to the unwinding screw hole. The top end of the inner unwinding shaft 21 is connected to the unwinding pressure plate 23, so that the unwinding pressure plate 23 can be screwed into the unwinding screw hole and the strip coil abuts against the unwinding reel 2 and the unwinding pressure plate 23. The two unwinding rings 22 are arranged in a manner that prevents the steel strip coil from shifting vertically during unwinding. The top of the unwinding inner shaft 21 is also equipped with a handle that tilts horizontally to one end. The bottom of the unwinding reel 2 has an unwinding shaft 24 along its central axis. The unwinding shaft 24 extends through a through hole in the corresponding circular groove to the bottom of the processing table 1. A thrust ball bearing is provided between the unwinding shaft 24 and the inner wall of the corresponding circular groove. The two unwinding collars 22 are of different sizes. The inner diameter of the larger unwinding collar 22 matches the outer diameter of the smaller unwinding collar 22, while the inner diameter of the smaller unwinding collar 22 matches the diameter of the unwinding shaft. This allows the two unwinding collars 22 to be nested sequentially on the unwinding inner shaft 21 from smallest to largest, with the outer ring wall of the unwinding collar 22 furthest from the unwinding inner shaft 21 abutting against the inner wall of the steel strip coil.

[0029] See Figure 2 and Figure 3The take-up shaft includes an inner take-up shaft 31, a take-up pressure plate 33, and two take-up collars 32. The top of the take-up reel 3 has a take-up screw hole along its central axis. The bottom end of the inner take-up shaft 31 has an external thread that matches the take-up screw hole. The top end of the inner take-up shaft 31 is connected to the take-up pressure plate 33, allowing the take-up pressure plate 33 to be screwed into the take-up screw hole and to abut the steel strip coil between the take-up reel 3 and the take-up pressure plate 33, thus preventing vertical displacement of the steel strip coil during take-up. The top end of the inner take-up shaft 31 also has a handle that tilts horizontally to one end. The bottom of the take-up reel 3 has a release shaft 24 along its central axis, which extends through a through hole in the corresponding circular groove to the processing area. Below the table 1, a thrust ball bearing is provided between the unwinding shaft 24 and the inner wall of the corresponding circular groove; the two take-up collars 32 are of different sizes, the inner diameter of the larger take-up collar 32 is adapted to the outer diameter of the smaller take-up collar 32, and the inner diameter of the smaller take-up collar 32 is adapted to the diameter of the take-up shaft, so that the two take-up collars 32 can be nested on the inner take-up shaft 31 in order of increasing size, and the outer ring wall of the take-up collar 32 furthest from the inner take-up shaft 31 can abut against the inner wall of the steel strip coil, so that the user can select the appropriate size and number of unwinding collars 22 and take-up collars 32 according to the inner diameter of different steel strip coils, thereby enabling the unwinding shaft and take-up shaft to adapt to steel strip coils of various specifications.

[0030] See Figure 2 and Figure 3 The take-up shaft 34 has, from top to bottom, a contact protrusion 344, a smooth rod section, and a threaded section. A friction ring 341 is fitted on the smooth rod section, and an adjusting nut 342 is screwed onto the threaded section. A washer 343 is provided between the friction ring 341 and the adjusting nut 342. The adjusting nut 342 can abut the friction ring 341 and the washer 343 between the adjusting nut 342 and the contact protrusion 344, so that the user can adjust the clamping force on the friction ring 341 by adjusting the adjusting nut 342, thereby adjusting the friction force between the friction ring 341 and the take-up shaft 34. The drive assembly 4 includes a drive motor 41 and a belt 42. The drive motor 41 is located below the table of the processing table 1. The output shaft of the drive motor 41 is connected to the put-out shaft 24 and the take-up shaft 34 via the belt 42.

[0031] The working principle of the semi-automatic rewinding machine for small-coil steel strips in this application is as follows:

[0032] After collecting the multiple small coils of steel strip 6 remaining from the steel product manufacturing equipment, the user can first place one small coil of steel strip 6 on the unwinding shaft and another small coil of steel strip 6 on the take-up shaft. Then, the two small coils of steel strip 6 are glued together at one end using tape, glue, or other means. Next, the drive assembly 4 is started to drive the unwinding reel 2 and the take-up reel 3 to rotate in the same direction, so that the small coils of steel strip 6 on the unwinding shaft can be wound onto the small coils of steel strip 6 on the take-up shaft. After the small coils of steel strip 6 on the unwinding shaft are unwound, the user can replace the small coils of steel strip 6 on the unwinding shaft and repeat the above operation. After repeating this process multiple times, the user can use the semi-automatic small coil rewinding machine to combine the multiple small coils of steel strip 6 into a large coil of steel strip 5, so that the steel product manufacturing equipment can continue to produce steel products using this large coil of steel strip 5, thereby ensuring full utilization of the steel strip coils and saving resources and production costs.

[0033] As unwinding and rewinding continue, the diameter of the steel strip on the unwinding shaft decreases while the diameter of the steel strip on the rewinding shaft increases. Consequently, the length of steel strip released per revolution on the unwinding shaft becomes less than the length of steel strip wound per revolution on the rewinding shaft. The friction ring 341 ensures that the rewinding disc 3 stops rotating after winding up the steel strip released by the unwinding shaft and tensions the steel strip between the rewinding and unwinding shafts until the unwinding shaft continues to release a portion of the steel strip. This allows the take-up reel 3 to freely adjust its rotational speed according to the speed at which the unwinding shaft releases the steel belt; it also transfers the friction that should occur between the belt 42 and the take-up shaft 34 to the friction ring 341 and the take-up shaft 34, thus protecting the belt 42; the user can also adjust the tension of the friction ring 341 by adjusting the nut 342, thereby adjusting the friction between the friction ring 341 and the take-up shaft 34, and thus adjusting the tension of the steel belt between the take-up shaft and the unwinding shaft.

[0034] It should be noted that the above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
