[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figures 1-3 A band saw blade winding device includes a worktable 1, on which a winding structure 3, a limiting structure 4 and a guide wheel 5 are provided;

[0021] The winding structure 3 is used to wind up the band saw blade body 2. The limiting structure 4 is located outside the winding structure 3 and is used to limit the winding position of the band saw blade body 2. The guide wheel 5 is located at the front end of the worktable 1 and is used to guide the band saw blade body 2 into the winding path.

[0022] Reference Figures 1-3 As shown, the winding structure 3 includes a drive motor 31, a rotating shaft 32, and a rotating drum 33; the drive motor 31 is fixed to the bottom of the worktable 1, and its output end is connected to the rotating shaft 32 for transmission; the bottom of the rotating drum 33 is fixedly connected to the top of the rotating shaft 32, the outer peripheral wall of the rotating drum 33 is provided with a guide hole 34, the inner wall of the rotating drum 33 is fixedly installed with an S-shaped limiting block 35, the upper surface of the S-shaped limiting block 35 is provided with a snap-fit ​​groove 36; a plurality of limiting plates 37 evenly distributed along the circumference are fixedly installed at the top of the outer peripheral wall of the rotating drum 33.

[0023] In this embodiment, the drive motor 31 drives the drum 33 to rotate automatically through the rotating shaft 32, replacing manual winding, reducing labor intensity and improving work efficiency; the double guide wheels 5 are symmetrically arranged, and the wheel surface guides the band saw blade body 2 to smoothly enter the winding path, reducing feeding resistance and deviation risk, and ensuring a continuous and smooth winding process.

[0024] Reference Figures 1-3 As shown, the limiting structure 4 includes a T-slot 41 opened on the workbench 1, a T-block 42 that slides with the T-slot 41, and a U-shaped frame 43 fixed above the T-block 42; a roller 44 is rotatably connected inside the U-shaped frame 43 via a rotating shaft, the rolling surface of the roller 44 abuts against the side of the band saw blade body 2, and a resistance spring 45 is fixedly installed on one outer wall of the U-shaped frame 43, and the other end of the resistance spring 45 is connected to a fixing plate 46 fixed to the upper surface of the workbench 1.

[0025] In this embodiment, the roller 44 in the limiting structure 4 elastically abuts against the side of the band saw blade body 2 through the resistance spring 45, which can automatically adapt to band saw blade bodies 2 of different widths and continuously provide stable clamping force without the need for frequent manual adjustments; the sliding cooperation between the T-slot 41 and the T-block 42 allows the limiting structure 4 to move laterally along the worktable 1, flexibly adapting to different winding position requirements and improving the versatility of the device.

[0026] Reference Figure 1As shown, there are two guide wheels 5, which are symmetrically arranged on both sides of the front end of the workbench 1, and the band saw blade body 2 is movably connected between the wheel surfaces of the two guide wheels 5.

[0027] Reference Figure 1 , Figure 2 As shown, one end of the band saw blade body 2 is engaged in the engagement groove 36. When the rotating drum 33 rotates, it drives the band saw blade body 2 to rewind around its outer circumference through the engagement groove 36.

[0028] Reference Figures 1-3 As shown, the cross-sectional shape of the snap-fit ​​groove 36 is adapted to the end shape of the band saw blade body 2. After the end of the band saw blade body 2 is inserted into the snap-fit ​​groove 36, it is fixed by interference fit or shape locking.

[0029] When in use, one end of the band saw blade body 2 is inserted into the locking groove 36 of the S-shaped limiting block (35) on the inner wall of the rotating drum 33. Since the cross-sectional shape of the locking groove 36 is adapted to the shape of the end of the band saw blade (such as rectangular, trapezoidal, etc.), the initial fixation is achieved through interference fit or shape locking to ensure that the end does not slip when winding. The other end of the band saw blade body 2 passes between the two guide wheels 5 at the front end of the worktable 1. The wheel surface of the guide wheel 5 is matched with the outer wall of the band saw blade body 2 to guide it to smoothly enter the winding area along the preset path and avoid feeding deviation.

[0030] After the drive motor 31 is powered on, it drives the rotating shaft 32 to rotate through the output end, which in turn drives the rotating drum 33 to rotate around its axis. When the rotating drum 33 rotates, the locking groove 36 drives the fixed end of the band saw blade to rotate synchronously. The band saw blade body 2 gradually winds up around the outer circumference of the rotating drum 33. During this process, the guide hole 34 on the outer circumference wall of the rotating drum 33 is adapted to the outer wall of the band saw blade body 2. The outer wall of the band saw blade body 2 is embedded in the guide hole 34 to form an axial limit, ensuring that the band saw blade body 2 is neatly arranged along the axis of the rotating drum 33, and avoiding serpentine movement or overlap during winding.

[0031] In the limiting structure 4 located outside the winding structure 3, the roller 44 abuts against the side of the band saw blade body 2 by the elastic force of the resistance spring 45. The elastic deformation of the spring ensures that the roller 44 always maintains a stable clamping force on the band saw blade body 2, which can prevent the band saw blade from loosening during winding and can automatically adapt to band saw blades of different widths (the clamping force is adjusted by the spring compression). The T-block 42 of the limiting structure 4 slides in conjunction with the T-slot 41 on the worktable 1. When it is necessary to adjust the limiting position (such as to adapt to band saw blades of different lengths), the U-shaped frame 43 can be manually pushed to move the T-block 42 laterally along the T-slot 41. After releasing, the resistance spring 45 automatically locks the position, achieving rapid calibration. The limiting plate 37 at the top of the rotating drum 33 is evenly distributed circumferentially and extends towards the center of the rotating drum 33 to form an annular limiting boundary.

[0032] During the winding process, the limiting plate restricts the radial displacement of the band saw blade to prevent the band saw blade from loosening and falling off when the roll diameter is too large, ensuring that the roll shape is compact and regular; the continuous rotation of the drive motor 31 realizes the automatic winding of the band saw blade without manual intervention, which significantly improves efficiency compared with the traditional manual winding method.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
