[0030] In an embodiment of the present utility model, as Figures 1 to 3 shown, a manual driving device for a reel machine is provided, which includes a ratchet wheel 10, a winding spring 20, a spring box 30 and a limiting device 40. An installation column 14 is arranged on the side surface of the ratchet wheel 10. Convex teeth inclined in the same direction are arranged on the edge of the ratchet wheel 10. The unidirectional rotation of the ratchet wheel 10 is restricted by engaging with the limiting device 40. The installation column 14 is located at the central position on the side surface of the ratchet wheel 10. One end of the installation column 14 passes through the spring box 30. The winding spring 20 is sleeved on the installation column 14, and one end of the winding spring 20 is engaged with the installation column 14. The winding spring 20 is located in the spring box 30, and the other end of the winding spring 20 is engaged with the side wall of the spring box 30. The moving end of the limiting device 40 is engaged with the edge of the ratchet wheel 10. By adjusting the ratchet wheel 10, the engaging position with the limiting device 40 is changed.

[0031] According to different operation requirements such as the length of the rotating shaft of the reel machine, the length of the winding pipe or the weight of the winding pipe, by replacing the installation column 14 with different lengths, different numbers of winding springs 20 are adapted to be arranged at intervals and engaged with the installation column 14. Correspondingly, the corresponding spring boxes 30 are assembled according to the number of winding springs 20 to accommodate each winding spring 20, and the spring boxes 30 are connected to each other. At the same time, the other ends of the winding springs 20 are respectively engaged with the side walls of the spring boxes 30. By selecting the length of the corresponding installation column 14, different numbers of winding springs 20 and spring boxes 30 are assembled to adapt to different operation requirements.

[0032] The manual driving device of the reel machine in the present utility model is assembled by a ratchet wheel 10, a winding spring 20, a spring box 30 and a limiting device 40. The ratchet wheel 10 is fixedly installed at one end of the rotating shaft of the reel machine, and an installation post 14 is arranged at the central position of the ratchet wheel 10. The installation post 14 is connected to the installation bracket of the equipment to establish a positional relationship with the winding spring 20 and the spring box 30. The spring box 30 is fixedly installed on the installation bracket of the reel machine, so that the position of the spring box 30 is always fixed, while the ratchet wheel 10 can rotate with the rotating shaft. The limiting device 40 is installed on the reel machine and is used to engage with the edge of the ratchet wheel 10. During assembly, first install the ratchet wheel 10 at one end of the rotating shaft, and install the limiting device 40 on the reel machine, and ensure that one end of the limiting device 40 can always abut against the edge of the ratchet wheel 10 in the initial state to limit the one-way rotation of the ratchet wheel 10. The installation post 14 provided on the ratchet wheel 10 is rotatably connected to the installation bracket of the equipment. The spring box 30 is fixedly installed on the installation bracket of the equipment. One end of the installation post 14 extends outwards through the spring box 30. One end of the winding spring 20 is engaged with the installation post 14, and the winding spring 20 is located in the spring box 30. After the winding spring 20 is wound around the installation post 14, the other end of the winding spring 20 is engaged with the spring box 30. The spring box 30 houses the winding spring 20 to achieve a certain protection function. The other end of the winding spring 20 is engaged with the spring box 30, and when one end of the winding spring 20 rotates with the installation post 14, the self-restoring ability of the winding spring 20 can be used to pull back the installation post 14 to rotate, preventing the rotating shaft of the reel machine from rotating easily and causing the wound product to become loose. At the same time, the ratchet wheel 10 can be manually rotated to change the engagement relationship between the limiting device 40 and the ratchet wheel 10. Through the above structural settings, manual adjustment of the winding state of the product on the rotating shaft of the reel machine is realized.

[0033] In another embodiment of the present utility model, as Figures 1 to 3 shown, the ratchet wheel 10 further includes an installation plate 11, a first limiting plate 12 and a second limiting plate 13. Connecting side plates perpendicular to the plane of the installation plate 11 and extending upwards are provided at both ends of the installation plate 11. The first limiting plate 12 and the second limiting plate 13 are respectively connected to the two connecting side plates, creating a height difference between the first limiting plate 12 and the second limiting plate 13 and the installation plate 11, which facilitates the engagement and limitation between the first limiting plate 12 and the second limiting plate 13 and the limiting device 40. The installation post 14 is installed at the central position on the side of the installation plate 11. Both the first limiting plate 12 and the second limiting plate 13 are connected to the edge of the installation plate 11, and the installation plate 11 is located between the first limiting plate 12 and the second limiting plate 13. The movable end of the limiting device 40 can be engaged with the edges of the first limiting plate 12 and the second limiting plate 13 to limit the one-way rotation of the ratchet wheel 10 and fix its rotation angle.

[0034] In another embodiment of the present utility model, as Figures 1 to 3As shown, a number of connected limiting teeth are provided at the edges of the first limiting plate 12 and the second limiting plate 13. The moving end of the limiting device 40 is engaged and positioned with each limiting tooth, and each limiting tooth is inclined in the same direction, thereby restricting the one-way rotation of the ratchet wheel 10 after being engaged with the limiting device 40.

[0035] In another embodiment of the present utility model, as Figures 1 to 3 shown, the limiting device 40 includes a return spring 41 and a limiting plate 42. The return spring 41 pulls the limiting plate 42 to maintain the engaged state. A rotating mounting hole is provided in the middle area of the limiting plate 42. One end of the limiting plate 42 is engaged with the edge of the ratchet wheel 10, and the other end of the limiting plate 42 is connected to one end of the return spring 41. The return spring 41 pulls the limiting plate 42 to rotate around the rotating mounting hole 11, so that the end of the limiting plate 42 is always engaged with the edge of the ratchet wheel 10. Rotate the limiting plate 42 to disengage it from the engaged state with the ratchet wheel 10, and then rotate the ratchet wheel 10 to adjust the angle of the ratchet wheel 10. Under the pulling of the return spring 41, the limiting plate 42 resumes the engaged state with the ratchet wheel 10, restricting the rotation of the ratchet wheel 10.

[0036] In another embodiment of the present utility model, as Figures 2 to 3 shown, a rotating sleeve seat 50 is provided on the ratchet wheel 10. The mounting post 14 passes through the rotating sleeve seat 50 and is rotatably connected to the rotating sleeve seat 50. The rotating sleeve seat 50 is located between the ratchet wheel 10 and the spring box 30. On the one hand, the rotating sleeve seat 50 is used to provide a connection with the equipment mounting bracket, and on the other hand, it ensures that the friction during the rotation of the mounting post 14 is minimized, facilitating the rotation of the mounting post 14.

[0037] In another embodiment of the present utility model, as Figures 2 to 3 shown, the rotating sleeve seat 50 includes a mounting cylinder 51, a fixing ring 52, and a connecting bearing 53. The connecting bearing 53 assists the rotation of the mounting post 14. The connecting bearing 53 is sleeved on the mounting post 14, and the inner ring of the connecting bearing 53 is connected to the mounting post 14. The connecting bearing 53 is located in the mounting cylinder 51, and the outer ring of the connecting bearing 53 is connected to the mounting cylinder 51. The inner ring edge of the fixing ring 52 is connected to the opening edge of one end of the mounting cylinder 51 for fixing and mounting on the equipment frame, and the fixing ring 52 is adjacent to the spring box 30. The fixing ring 52 fixes the position of the rotating sleeve seat 50, enabling the mounting seat to rotate through the connecting bearing 53 at a fixed position.

[0038] In another embodiment of the present utility model, as Figure 2 shown, a first clamping hole 141 is provided on the side wall of the mounting post 14. One end of the coil spring 20 is clamped with the first clamping hole 141, and multiple first clamping holes 141 can be provided for the installation and assembly of the coil spring 20.

[0039] In another embodiment of the present utility model, asFigure 2 As shown, a first clamping hole 141 extends upward through the top of the mounting post 14. The coil spring 20 is directly slid into the first clamping hole 141 through this notch, realizing the assembly between the coil spring 20 and the mounting post 14, so that one end of the coil spring 20 rotates following the mounting post 14.

[0040] In another embodiment of the present invention, as Figure 2 shown, a second clamping hole 31 is formed on the side surface of the spring box 30. The other end of the coil spring 20 is clamped with the second clamping hole 31, so that the clamping position of the other end of the coil spring 20 is fixed and will not be driven to move due to the rotation of one end of the coil spring 20 following the mounting post 14. After one end of the coil spring 20 rotates, a restoring force is generated to urge the mounting post 14 to rotate back, ensuring that the product wound around the rotating shaft will not become loose.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
