DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Please refer to Figures 1-5As shown, an embodiment of the present application provides a technical solution: a steel wool rolling machine, comprising an upper roller 11 for rolling cotton, and a rotating mechanism 2 for driving the upper roller 11 to rotate, the rotating mechanism 2 comprising a cantilever shaft 21 arranged on a bearing seat 22, a limiting support block 23 is arranged on one side of the cantilever shaft 21 close to the bearing seat 22, and a detachable fixing block 24 for fixing the upper roller 11 is arranged on the other side of the cantilever shaft 21, and the upper roller 11 is arranged between the limiting support block 23 and the fixing block 24.

[0022] By inserting the cantilever shaft 21 into the upper roller 11, it is ensured that even if there is no support on both sides of the upper roller 11, the upper roller 11 will be supported on the cantilever shaft 21, so it is not easy to fall. The purpose of setting the cantilever shaft 21 is to facilitate the removal of the upper roller 11 rolled with steel wool from one side after the upper roller 11 completes the cotton rolling.

[0023] In the preferred embodiment, a through hole 111 is provided in the length direction of the upper roller 11, and the limiting support block 23 includes a first boss 231 and a second boss 232. The first boss 231 is tightly inserted into the through hole 111 of the upper roller 11, and the second boss 232 is against one side of the upper roller 11. A plurality of protrusions 25 are evenly arranged in the circumference of the fixing block 24, and the protrusions 25 are tightly stuck in the through hole 111.

[0024] The purpose of providing the first boss 231 and the protrusion 25 is to reduce the gap between the upper roller 11 and the cantilever shaft 21 and reduce the shaking during movement.

[0025] In a preferred solution, an inner hole 241 is provided in the fixing block 24 , a thread is provided on the inner hole 241 , an outer thread is provided at a corresponding position of the cantilever shaft 21 , and the fixing block 24 is connected to the cantilever shaft 21 through threads.

[0026] In this way, the fixing block 24 can be easily removed from one side, thereby making it easy to remove the upper roller 11 .

[0027] In the preferred embodiment, the rotating mechanism 2 also includes a motor base 26 arranged on a flat plate 28, a motor 27 is provided on the motor base 26, a synchronous pulley is provided on the rotating shaft of the motor 27, and a synchronous pulley is also provided on the side corresponding to the cantilever shaft 21. The motor 27 drives the cantilever shaft 21 to rotate by setting a synchronous belt between the two synchronous pulleys.

[0028] In the preferred embodiment, a corresponding lower roller mechanism 3 is provided below the upper roller 11, and the lower roller mechanism 3 includes a first U-shaped seat 31 provided below the flat plate 28, a cylinder 32 is provided inside the first U-shaped seat 31, a connecting piece 33 is provided on the extending shaft of the cylinder 32, a second U-shaped seat 34 is provided on the connecting piece 33, and a lower roller 35 is provided on the second U-shaped seat 34.

[0029] When starting to wind the steel wool, the lower roller mechanism 3 moves upward and leans against the lower part of the upper roller 11, so as to better flatten the wound steel wool. The connection method between the lower roller 35 and the second U-shaped seat 34 is the same as the connection method between the upper roller 11 and the bearing seat 22 in principle, so it will not be elaborated here.

[0030] In a preferred solution, a fixed support 36 is further provided on the first U-shaped seat 31. A guide shaft 37 is provided in the fixed support 36. A guide shaft support 38 is provided on the connecting member 33, and the guide shaft support 38 moves along the guide shaft 37.

[0031] When the cylinder 32 pushes the connecting member 33 to move, the guide shaft support 38 moves along the guide shaft 37.

[0032] In a preferred solution, the fixing block 24 is a plastic part. The main reason is that the plastic part is softer than metal and can withstand more interference fits, so as to better fit into the through hole 111 of the upper roller 11.

[0033] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
