[0002] In the production and processing of steel strip, winding equipment is needed to wind spring steel strip into a ring shape.

Detailed Implementation

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] like Figure 1-5 As shown, this utility model is a steel strip winding anti-loosening device, including a mounting base 1 with positioning blocks 11. The positioning blocks 11 are fixedly connected to the four lower corners of the mounting base 1. They can be fixed to the frame for combined use by connecting bolts through the mounting holes in the positioning blocks 11, or they can be installed with rollers and connected to the track to move and align with the winding position of the steel strip. It can be adjusted for use. The upper end of the mounting base 1 is provided with a side plate 12, and the upper end of the side plate 12 is fixedly connected with a mounting plate 13. A telescopic rod 14 is fixedly installed on the upper surface of the mounting plate 13. The lower end of the telescopic rod 14 is provided with an elastic component 15, which can be adjusted by telescopically extending and retracting the telescopic rod 14, thereby controlling the up and down movement of the elastic component 15, which is convenient for alignment and winding. This allows for elastic compression, thereby reserving a certain buffer height. As the winding thickness increases, the height can be slowly raised to avoid interference and jamming. The lower end of the elastic component 15 is fixedly installed with a mounting frame 16, which can rotate internally. A rotating shaft 17 is installed inside the mounting frame 16 for rotational support. It can be matched with the position of the winding drum to assist in positioning, ensure the tightness of winding, and prevent loosening. The front end of the mounting frame 16 is provided with a guide rod 18, which is slidably installed on the surface of the side plate 12. By sliding along the surface of the side plate 12, the guide rod 18 can guide and support the mounting frame 16, prevent lateral movement, and improve the stability of vertical adjustment. The surface of the rotating shaft 17 is provided with an anti-loosening component 2, which includes a pressure roller 21 and a connecting cylinder 22. The connecting cylinder 22 is fixedly connected to both ends of the pressure roller 21. Both the pressure roller 21 and the connecting cylinder 22 are sleeved on the outer surface of the rotating shaft 17. By installing the pressure roller 21 at both ends of the rotating shaft 17, it can be aligned with the two edges of the steel strip winding position to assist in pressing and winding. This can ensure stability, reduce the contact area, reduce rotational resistance, avoid interference with the winding process, and facilitate combined use.

[0021] In practical use, first position the mounting base 1 so that it can be used in combination with the winding equipment. This allows the mounting frame 16 to be aligned above the winding drum. During the winding process, control the extension rod 14 to extend, and in conjunction with the elastic component 15, push the mounting frame 16 downward, moving the rotating shaft 17 and the pressure roller 21 downward. Manually adjust the installation spacing of the pressure roller 21 to correspond to the two sides of the steel strip roll. This, combined with the winding drum, can assist in pressing, thus improving the tightness of the winding and preventing excessive gaps, effectively improving the anti-loosening effect. As the winding thickness increases, the extension rod 14 can be slowly retracted to lift the mounting frame 16 and the pressure roller 21, which can accommodate the winding thickness at different times and is easy to adjust. During the lifting process, the elastic component 15 can provide elastic buffering, thus reserving a certain buffer gap to avoid direct jamming and interference.

[0022] Furthermore, the surface of the rotating shaft 17 is provided with connecting through holes 23, which are equally spaced at both ends of the rotating shaft 17. The equally spaced connecting through holes 23 allow the pressing roller 21 to be installed in different positions, thereby changing the pressing distance.

[0023] Furthermore, the connecting cylinder 22 has combined through holes 24 on both sides, and the combined through holes 24 are aligned with the connecting through holes 23;

[0024] Furthermore, a combination screw 25 is installed inside the combined through hole 24. The combination screw 25 is inserted into the inside of the connecting through hole 23. By installing the combination screw 25 through the combined through hole 24, it can be aligned with the connecting through hole 23, thereby fixing the connecting cylinder 22 to the rotating shaft 17. This also allows the position of the pressing roller 21 to be positioned, so that it can rotate synchronously with the rotating shaft 17. By installing it on the connecting through hole 23 at different positions, the distance between the two pressing rollers 21 can be changed, making it highly adaptable.

[0025] Furthermore, the elastic component 15 includes a push rod 3 and a sleeve 31. The sleeve 31 is fitted onto the outer surface of the push rod 3. The push rod 3 is fixedly connected to the lower end of the rod head of the telescopic rod 14. The sleeve 31 is fixedly connected to the upper surface of the mounting bracket 16. The sliding fit between the sleeve 31 and the push rod 3 facilitates adjustment and makes it easy to use in combination.

[0026] Furthermore, the lower end of the push rod 3 is provided with a push block 32, which is slidably installed inside the sleeve 31. The push block 32 is connected to the push rod 3, which can be combined and positioned with the sleeve 31, which is conducive to sliding adjustment while avoiding separation and detachment, and has high stability.

[0027] Furthermore, the lower end of the sleeve 31 is provided with a countersunk hole 33, and a support spring 34 is slidably installed inside the countersunk hole 33. The support spring 34 presses against the lower end of the push block 32. The support spring 34 is connected to the push block 32 to form an elastic connection structure, which is conducive to buffering and avoidance.

[0028] In practical use, the push rod 3 is pushed by the telescopic rod 14, which raises and lowers the sleeve 31, thus aligning the mounting frame 16. First, the support spring 34 is pushed by the push block 32, which elastically compresses the support spring 34 and presses down the mounting frame 16, thereby pushing the pressure roller 21 to elastically press against the surface of the steel strip coil, avoiding direct interference and jamming. Then, the pressure continues to be applied, and the push block 32 compresses the support spring 34 into the countersunk hole 33, which can directly and rigidly push the sleeve 31, thus ensuring sufficient pressure and facilitating stable positioning in the early stages of winding. As the winding thickness increases, the telescopic rod 14 is controlled to return to its original position with the push rod 3, and the support spring 34 is pushed upward, forming an elastic pressing state. This provides a certain buffer space to ensure the safety of the telescopic rod 14's return and reset, making it highly adaptable.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
