[0024] The lower position of rotating disc 2 is opened with snap spring groove, and the snap spring groove is fixed with snap ring 5, and the snap ring 5 axially positions the rotating disc 2, and the lower portion of the snap ring 5 is provided with a bearing seat 4, and the outer side of the bearing seat 4 is fixedly installed with a base 7, and the base 7 is opened with an annular stepped groove, and the annular stepped groove is fixedly installed with a lower radial bearing 10 inside, and the lower radial bearing 10 is sleeved on the outside of the rotating shaft 1, and the lower radial bearing 10 is used to bear radial load.

[0025] The rotating disc 2 is uniformly distributed with three groups of winding drums 14, and the outer side of each group of winding drums 14 is provided with two groups of check rings 12.

[0026] The check ring 12 includes an elastic coil 15 and a plurality of lower check ring assemblies 13, the plurality of lower check ring assemblies 13 form a circle, each lower check ring assembly 13 is opened with a hollow layer inside, the elastic coil is placed in the hollow layer inside the plurality of lower check ring assemblies 13, the plurality of lower check ring assemblies 13 are connected in series, and the lower check ring assemblies 13 are movable through the elastic force of the elastic coil 15.

[0027] The upper blocking ring assembly 17 is fixedly installed above each group of lower blocking ring assemblies 13, and the air pressure telescopic rod 18 is fixedly installed on the side of each group of upper blocking ring assemblies 17 away from the lower blocking ring assembly 13. The output end of each group of air pressure telescopic rods 18 is fixedly connected with the blocking ring extension piece 16, and a plurality of blocking ring extension pieces 16 form a circle.

[0028] The lower blocking ring assembly 13 is made of magnetic material.

[0029] A plurality of mounting holes are formed in the bottom 7, so that the bottom 7 can be mounted on the machine body.

[0030] The winding drum 14 is marked with a scale line.

[0031] Working principle:

[0032] The winding drum 14 is installed on the rotating disc 2, and the rotating shaft 1 drives the rotating disc 2 to rotate through the spline connection, thereby driving the winding drum 14 to rotate. In actual operation, the working position of the winding drum 14 can be freely selected, and various working conditions can be effectively coped with. When different production specifications are encountered, the corresponding threaded holes of the rotating disc 2 and the winding drum 14 can be used to flexibly install winding drums 14 of different diameters on the same machine, thereby effectively saving production costs.

[0033] Two groups of blocking rings 12 are installed on the column body of the winding drum 14. The two groups of blocking rings can be set at different distances according to the winding needs. The blocking ring 12 is fixedly adsorbed on the outer surface of the winding drum 14 by the magnetic force of the lower blocking ring assembly 13, so as to prevent the blocking ring 12 from falling off during work.

[0034] The elastic coil 15 arranged in the hollow layer of the lower blocking ring assembly 13 can freely stretch and contract. When a winding drum 14 with a larger diameter is selected, the elastic coil 15 is stretched to drive the lower blocking ring assembly 13 to move, thereby increasing the diameter of the circle surrounded by the lower blocking ring assembly 13, so as to adapt to different diameter specifications of the winding drum 14.

[0035] The air pressure telescopic rod 18 drives the telescopic movement of the blocking ring extension piece 16. In the non-working state, the air pressure telescopic rod 18 is retracted to drive the blocking ring extension piece 16 to retract inward and close to the upper blocking ring assembly 17, thereby saving space. In the working state, the air pressure telescopic rod 18 drives the blocking ring extension piece 16 to open outward as the thickness of the rolled material increases. At this time, the blocking ring extension piece 16 and the upper blocking ring assembly 17 are in close contact with the rolled material, thereby preventing the rolled material from deviating during work.

[0036] The scale line on the column body of the winding drum 14 is used to position the working position of the two groups of blocking rings 12, so as to meet the winding needs of different specifications.
