DETAILED DESCRIPTION

[0025] The method for using the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Embodiment 1, as Figures 1 to 7 As shown, a winding inner cylinder device for reducing the abrasion of the outer ring of the coil includes: a base 1 and a push rod 2, the push rod 2 is provided on the base 1, and also includes: a cylinder 3 and an adjusting mechanism 4, the bottom of the cylinder 3 is provided with an adjusting mechanism 4, the cylinder 3 is composed of a plurality of arc plates 31, and the adjusting mechanism 4 is arranged on the base 1; the tops of adjacent arc plates 31 are driven away from each other by the adjusting mechanism 4, and at the same time tilted outward at a certain angle.

[0027] By pushing the push rod 2, when the red steel is pushed out of the cylinder 3, the adjusting mechanism 4 expands the diameter of the top opening of the cylinder 3, thereby increasing the gap between the outer ring surface of the red steel and the inner wall of the cylinder 3, preventing friction between the outer ring surface of the red steel and the inner wall of the cylinder 3, avoiding scratches on the outer ring surface of the red steel, and greatly improving the production quality of the red steel.

[0028] The arc plate 31 is inclined outward at an angle of 1-3 degrees. The inclination angle is adjusted according to the actual use environment to change the gap between the surface of the red steel outer ring and the inner wall of the cylinder 3.

[0029] The adjusting mechanism 4 includes: a gear ring 41, a support column 42, a support ring 43, a rotating shaft 44, a gear 45 and a rotating gear 46; the gear ring 41 is arranged on the top of the base 1, and a plurality of the support columns 42 are arranged in a ring array on the top of the base 1 and are located on the inner side of the gear ring 41; the support ring 43 is arranged on the top of the support column 42, and the support ring 43 is coaxial with the gear ring 41; a plurality of the rotating shafts 44 are arranged in a vertical ring array on the top of the base 1, and a plurality of the rotating shafts 44 pass through the support ring 43, and a plurality of the rotating shafts 44 are arranged at intervals with a plurality of the support columns 42; a plurality of the gears 45 are arranged at the bottom of the rotating shaft 44, and a plurality of the gears 45 are respectively meshed with the teeth on the inner wall of the gear ring 41; and a plurality of the rotating teeth 46 are respectively arranged on the top of a plurality of the rotating shafts 44.

[0030] The power is thus transmitted to the gear 45 through the gear 45. The rotation of the gear 45 will drive the shaft 44 to rotate together. The shaft 44 will also drive the rotating gear 46 to rotate, thereby driving the second tooth 318 and the third tooth 319 which are meshed with the rotating gear 46, so that the tops of adjacent arc plates 31 are moved away from each other, and the diameter of the opening on the cylinder 3 will be expanded, thereby realizing the expansion of the gap between the outer ring surface of the red steel and the inner wall of the cylinder 3, preventing friction between the outer ring surface of the red steel and the inner wall of the cylinder 3, and avoiding scratches on the outer ring surface of the red steel.

[0031] A plurality of first teeth 411 are disposed on the outer circumferential surface of the gear ring 41 , a driving tooth 5 is disposed between the base 1 and the push rod 2 , and the driving tooth 5 and the first teeth 411 are meshed with each other.

[0032] The worker manually pushes the push rod 2 to drive the driving tooth 5 to rotate, and the driving tooth 5 will drive the first tooth 411 to rotate, and the rotating shaft 44 to rotate, so that the tops of each adjacent arc plate 31 are separated from each other, and the top diameter of the cylinder 3 is exaggerated.

[0033] The arc plate 31 has a first extension portion 311, a second extension portion 312 and a third extension portion 313 on one side; and a fourth extension portion 314, a fifth extension portion 315 and a sixth extension portion 316 on the other side. The first extension portion 311 and the third extension portion 313 on one side of the arc plate 31 and the fourth extension portion 314 and the sixth extension portion 316 on the other side of the other arc plate 31 are matched and spliced ​​with each other, and the second extension portion 312 and the fifth extension portion 315 are parallel to each other to form a cavity 317, and the rotating shaft 44 is located inside the cavity 317.

[0034] A plurality of second teeth 318 and a third tooth 319 are respectively disposed on opposite surfaces of the top of the second extension portion 312 and the fifth extension portion 315 , and the second teeth 318 and the third teeth 319 are located outside the rotating teeth 46 and mesh with the rotating teeth 46 .

[0035] The rotating teeth 46 drive the second teeth 318 and the third teeth 319 that mesh with each other, so that the second extension portion 312 and the fifth extension portion 315 move away from each other, and each arc plate 31 tilts outward at a certain angle, thereby achieving an expansion of the top diameter of the entire cylinder 3.

[0036] The outer circumferential surface of the cylinder 3 has a plurality of reinforcing ribs 6 arranged in a linear array to increase the strength of the cylinder 3. The reinforcing rib 6 is composed of a plurality of arc-shaped connecting members 61 , one end of which is provided with an arc-shaped groove 611 , and the other end of which is provided with an arc-shaped protrusion 612 , and the arc-shaped grooves 611 and the arc-shaped protrusion 612 at both ends of the plurality of arc-shaped connecting members 61 are interconnected and surround into an annular structure.

[0037] The arc-shaped connector 61 cooperates with the arc-shaped groove 611 and the arc-shaped protrusion 612 so that when the arc-shaped plate 31 is tilted, the arc-shaped protrusion 612 can slide in the arc-shaped groove 611, thereby ensuring the mobility of the arc-shaped plate 31 and the stability of the entire arc-shaped plate 31.

[0038] The outer circumferential surface of the bottom of each arc-shaped plate 31 on the cylinder 3 is connected to the support ring 43 via a hinge 7 .

[0039] It should be noted that, because the hinge 7 connects the arc plate 31 and the support ring 43, and the arc plate 31 can rotate at a certain angle in the support ring 43, in order to ensure that the arc plate 31 can rotate, a certain gap is left between the arc plate 31 and the support ring 43. When the top of the arc plate 31 tilts outward, it can be ensured that there is no interference between the arc plate 31 and the support ring 43, and the outward tilt angle of the top of each arc plate 31 is 1-3 degrees. By tilting outward, the gap between the outer ring surface of the red steel and the inner wall of the cylinder 3 is increased, preventing friction between the outer ring surface of the red steel and the inner wall of the cylinder 3, avoiding scratches on the outer ring surface of the red steel, and greatly improving the production quality of the red steel.

[0040] Working process: When taking the red steel out of the cylinder 3, first, it is necessary to push the push rod 2. One end of the push rod 2 rotates and drives the driving tooth 5 to rotate. Since the driving tooth 5 is meshed with the first tooth 411, the gear ring 41 will be driven to rotate a certain angle. During the rotation of the gear ring 41, the gear 45 inside the gear ring 41 will be driven to rotate. The gear 45 transmits power to the shaft 44, so that the shaft 44 drives the rotating tooth 46 at the top to rotate. The rotating tooth 46 is meshed with the second tooth 318 and the third tooth 319, which will drive the tops of the two adjacent arc plates 31 away from each other and expand the diameter of the opening on the cylinder 3. The inner walls of each arc plate 31 will tilt outward by 1-3°, and the hinge 7 at the bottom of the arc plate 31 will rotate with the tilt of the arc plate 31. At the same time, the reinforcing rib 6 on the outer side of the arc plate 31 will also expand and contract, and the arc protrusion on the adjacent arc connector 61 on the reinforcing rib 6 will slide in the arc groove 611.

[0041] Embodiment 2 is different from Embodiment 1 in that, in this embodiment, the push rod 2 can be driven by a motor. By connecting the motor to the driving tooth 5, the motor rotates and drives the driving tooth 5 to rotate, so that the tops of each adjacent arc plate 31 are moved away from each other, so that the gap between the outer ring surface of the red steel and the inner wall of the cylinder 3 is increased, and friction between the outer ring surface of the red steel and the inner wall of the cylinder 3 is prevented, thereby avoiding scratches on the outer ring surface of the red steel, and greatly improving the production quality of the red steel.

[0042] The motor can accurately control the rotation angle of the driving tooth 5, so as to realize the outward tilt angle of the top of the arc plate 31, and accurately adjust the gap between the surface of the red steel outer ring and the inner wall of the cylinder 3 to avoid scratches on the surface of the red steel outer ring.
