DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] See also Figure 1-4 The utility model provides an embodiment: a winding device for processing cold-rolled steel strips, comprising a mounting bracket 1, a winding drum 8 is mounted on one side of the mounting bracket 1, the winding drum 8 is arranged as a hollow structure, the winding drum 8 is connected to the mounting bracket 1 through a rotating sleeve 7, the rotating sleeve 7 is connected to the mounting bracket 1 through a bearing, a sliding groove 9 is provided on the front and rear ends of the outer surface of the winding drum 8, the sliding groove 9 is communicated with the inside of the winding drum 8, one end of the winding drum 8 is rotatably connected to an internal threaded rod 11 through a bearing, and the other end of the internal threaded rod 11 is connected to a driving shaft 1 0, a sliding baffle 12 is arranged on the winding drum 8, and the sliding baffle 12 includes a baffle body 13, a connecting block 14 and an intermediate sliding disk 15, and the connecting block 14 is located at the front and rear ends between the baffle body 13 and the intermediate sliding disk 15, and the baffle body 13, the connecting block 14 and the intermediate sliding disk 15 are integrally formed, and the baffle body 13, the connecting block 14 and the intermediate sliding disk 15 slide along the outside of the winding drum 8, the sliding slot 9 and the inside of the winding drum 8, and a threaded hole 16 is opened through the intermediate sliding disk 15, and the threaded hole 16 is connected to the internal threaded rod 11 by threads. A side bracket 2 is welded and fixed on the other side of the mounting bracket 1, and a first drive motor 3 is installed at the upper end of the outer side of the side bracket 2. The other end of the drive shaft 10 passes through the rotating sleeve 7 and is connected to the output shaft end of the first drive motor 3, and the drive shaft 10 is connected to the rotating sleeve 7 through a bearing; a second drive motor 4 is installed at the lower end of the outer side of the side bracket 2, and a first drive gear 5 is installed along the output shaft end of the second drive motor 4 between the mounting bracket 1 and the side bracket 2, and a first driven gear 6 is installed along the upper end of the first drive gear 5 between the mounting bracket 1 and the side bracket 2, and the first driven gear 6 is meshed with the first drive gear 5, and the first driven gear 6 has the same diameter as the first drive gear 5, and the rotating sleeve 7 is connected to the first driven gear 6.
[0024] The winding device is adjusted according to the width of the steel coil to be wound; the first driving motor 3 drives the driving shaft 10 to rotate, driving the internal threaded rod 11 to rotate, and the sliding baffle 12 is driven to slide through the threaded connection relationship between the internal threaded rod 11 and the threaded hole 16 of the middle sliding disk 15 on the sliding baffle 12, and the baffle body 13, the connecting block 14 and the middle sliding disk 15 slide along the outside of the winding drum 8, the sliding slot 9 and the inside of the winding drum 8, so that the width of the outside of the winding drum 8 along the outside of the sliding baffle 12 matches the width of the steel strip. The steel strip winding inner core is placed outside the winding drum 8, and the second driving motor 4 drives the first driving gear 5 to rotate, and the meshing connection relationship between the first driving gear 5 and the first driven gear 6 drives the first driven gear 6, the rotating sleeve 7 and the winding drum 8 to rotate, so as to wind the steel strip.
[0025] Since the rotation of the winding drum 8 will drive the sliding baffle 12 to rotate synchronously, affecting the position of the sliding baffle 12 outside the winding drum 8, the first drive motor 3 is required to drive the drive shaft 10 and the internal threaded rod 11 to rotate so that the sliding baffle 12 remains at a constant position outside the winding drum 8.
[0026] After the winding is completed, the first drive motor 3 drives the drive shaft 10 to rotate, driving the internal threaded rod 11 to rotate, and the threaded connection relationship between the internal threaded rod 11 and the threaded hole 16 of the middle sliding disk 15 on the sliding baffle 12 drives the sliding baffle 12 to slide. The sliding baffle 12 slides outward to push the wound steel belt outward, so that the steel belt reaches the bearing platform of the transfer device, and the wound steel belt is transferred by the transfer device.

The diameter of the second driven gear 20 is larger than the diameter of the second driving gear 19. The second driven gear 20 rotates at a low speed to drive the winding and pressing member 22 to move, so that the winding and pressing member 22 moves relatively slowly to match the gradually increasing diameter of the steel strip roll; the winding and pressing member 22 is composed of a fixed sleeve 23, an arc-shaped fixed arm 24 and a clamping wheel 25. The arc-shaped fixed arm 24 is fixed on both sides of the outside of the fixed sleeve 23, and the clamping wheel 25 is located at the other end between the two arc-shaped fixed arms 24. The clamping wheel 25 is rotatably connected to the arc-shaped fixed arm 24 through a bearing, and the clamping wheel 25 is located outside the cold-rolled steel strip and fits the outer surface of the cold-rolled steel strip.
[0028] During the winding process, the pressure wheel 25 of the winding pressure piece 22 presses the outer surface of the steel belt to avoid large gaps between the steel belts; as the winding work proceeds, the third drive motor 18 drives the second drive gear 19 to rotate, and through the meshing connection between the second drive gear 19 and the second driven gear 20, drives the connecting shaft 21 and the winding pressure piece 22 to rotate, keeping the pressure wheel 25 always pressed on the outer surface of the steel belt with gradually increasing diameter.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
