As the main component of belt conveyors, conveyor belts play a key role. However, due to the design structure and special material properties of conveyor belts, they are consumable spare parts and need to be replaced regularly. During the replacement process, how to effectively use conveyor belts has become a common challenge on site. Usually, belt winding is a routine operation. When replacing conveyor belts, due to their special design, it usually relies on manual labor and simple conveyor belt racks to disassemble and pack conveyor belts. Currently, the disassembly and packing process mainly relies on manually pushing the edge of the belt for operation. During the disassembly process of the conveyor belt, since it is originally in a rolled state and lacks fixed force-bearing points, the entire disassembly process is time-consuming and laborious. Content of the Utility Model

[0003] The purpose of the utility model is to provide a new type of manual conveyor belt winding device to solve the problems that it is necessary to rely on manual labor and simple conveyor belt racks to disassemble and pack conveyor belts. Currently, the disassembly and packing process mainly relies on manually pushing the edge of the belt for operation. During the disassembly process of the conveyor belt, since it is originally in a rolled state and lacks fixed force-bearing points, the entire disassembly process is time-consuming and laborious.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A new type of manual conveyor belt winding device, on which a belt is laid on a belt drum.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By connecting a threaded rod on the axis of the belt roller and arranging a sliding seat and a fixed seat on the threaded rod, the sliding seat can slide, thereby changing the angle between the second connecting rod and the first connecting rod to support the inner wall of the mounting hole opened on the axis of the belt roller. Subsequently, the sliding seat is limited and fixed by a limit nut locked by a double nut. Then, by rotating the tape winding rod for winding or unwinding the tape, the support and positioning requirements for mounting holes with different inner diameters are met.

[0014] 2. At the same time, by adjusting the adjusting lead screw of the lifting device, the sliders can move towards or away from each other, slightly lifting the belt roller to separate it from the ground contact. This compass-style disassembly method replaces the original operation that requires manual workers with no fixed force-bearing parts, greatly saving labor costs and facilitating the rapid disassembly of the conveyor belt. In the past, it usually required 6 - 8 people to disassemble the belt, but now this device only needs 3 - 4 people to complete, significantly saving labor and time costs. In addition, when the belt needs to be repacked, the operation can also be carried out by rotating the handle in the reverse direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1: Please refer to Figures 1 - 3, an embodiment provided by the present utility model: a new type of conveyor belt manual winding device. A belt is laid on the belt roller 1. An installation hole is opened on the axis of the belt roller 1. A manual winding device is connected to the installation hole, including a support device installed on the manual winding device, and a lifting device 10 installed at the bottom end of the support device.

[0025] The support device includes a threaded rod 2, a fixed seat 3, a first connecting rod 4, a second connecting rod 5, and a sliding seat 6. On the left and right sides inside the installation hole, threaded rods 2 are respectively arranged. The two threaded rods 2 are connected by a shaft. The bottom end of the threaded rod 2 is fixedly connected with a fixed seat 3. The fixed seat 3 is fixed at the bottom end of the threaded rod 2 to support the first connecting rod 4 and the second connecting rod 5. A number of first connecting rods 4 are evenly hinged on the outer circumference of the fixed seat 3 at an angle. The top end of the first connecting rod 4 is hinged to the second connecting rod 5. The other end of the second connecting rod 5 is hinged to the sliding seat 6. The sliding seat 6 is slidably fitted to the threaded rod 2. In the initial state, the first connecting rod 4 and the second connecting rod 5 are parallel to the threaded rod 2 through the movement of the sliding seat 6. After inserting the support device into the installation hole of the belt roller 1, by sliding the sliding seat 6, the second connecting rod 5 rotates, and at the same time, the distance from the fixed seat 3 is shortened, and the angle with the first connecting rod 4 is changed, so as to abut against the inner wall of the installation hole on the axis of the belt roller 1 for support. Since the sizes of the belt rollers 1 are different and the sizes of the installation holes on the axis are also different, the support device is adjusted to be suitable for supporting installation holes of different sizes, so as to perform winding or unwinding operations.

[0026] It further includes a limit nut 7. The limit nut 7 is composed of two nuts. The limit nut 7 is engaged on the threaded rod 2 and is located at the top end of the sliding seat 6 for limiting the sliding seat 6. The two nuts of the limit nut 7 have opposite thread directions. The limit nut 7 is composed of two nuts with opposite thread directions. After the limit nut 7 is rotated, when one nut moves in one direction under the action of external vibration, the other nut moves in the opposite direction, so as to maintain the stability of the sliding seat 6, avoid the sliding of the sliding seat 6 after installation, and make the support of the support device on the inner wall of the positioning hole unstable, resulting in poor winding or unwinding conditions.

[0027] The top end of the threaded rod 2 is fixedly connected with a winding rod 9. Personnel can operate the winding rod 9 on both sides of the belt roller 1, which speeds up the winding or unwinding operation and increases work efficiency.

[0028] It further includes a bearing seat 8, which is sleeved on the threaded rod 2 and is arranged at the thread termination end. The bottom end of the bearing seat 8 is connected with a lifting device 10. When the winding rod 9 drives the threaded rod 2 to rotate, since the bearing seat 8 is arranged at the thread termination end, it is convenient for the threaded rod 2 to rotate. At the same time, the bearing seat 8 enhances the overall structural stability, especially during long-term operation or high-frequency operation, it can reduce the friction and wear of the rods and extend the service life.

[0029] Embodiment 2: Please refer to Figure 4 , on the basis of Embodiment 1, the following structure is further provided:

[0030] The lifting device 10 includes a base housing, which provides structural support and stability for the entire device and contacts the ground to ensure the basic fixed position of the device, an adjusting lead screw 11, an inner shear, an outer shear, and a lifting plate 14. The base housing abuts against the ground. The adjusting lead screw 11 penetrates the front end of the base housing, and a adjusting handwheel is connected to the top end, and the other end abuts against the inner wall of the right end of the base housing. Two sliders 12 are slidably fitted on the adjusting lead screw 11. The sliders 12 are slidably fitted in the first chutes opened on the left and right sides of the base housing, which are used to support and guide the movement of the inner shear and the outer shear, ensuring the smooth movement of the inner shear and the outer shear, so that the lifting plate 14 can remain stable and reliable during the lifting process. The sliders 12 are slidably fitted in the first chutes opened on the left and right sides of the base housing. The inner shear and the outer shear are respectively connected to the sliders 12. The inner shear and the outer shear are hinged to each other. Slide bars 13 are respectively arranged at the top ends of the inner shear and the outer shear. The top ends of the slide bars 13 are connected to the lifting plate 14. The slide bars 13 are slidably fitted in the chutes opened on the left and right sides inside the lifting plate 14. The slide bars 13 slide in the chutes opened inside the lifting plate 14, and the chutes guide the slide bars 13 to ensure the smoothness during lifting. In the initial state, the lifting device 10 is connected to the bottom end of the bearing seat 8 and contacts the ground. By rotating the adjusting handwheel, the adjusting lead screw 11 is driven to rotate, moving the sliders 12 towards each other, changing the angle between the inner shear and the outer shear. The slide bars 13 at the top ends of the inner shear and the outer shear slide in the chutes inside the lifting plate 14, lifting the lifting plate 14, thereby slightly lifting the belt roller 1. Rotate the tape winding rod 9 to wind or unwind the tape. The adjusting lead screw 11 is composed of two lead screws with opposite helix directions, which are used to slide the sliders 12 towards each other or away from each other.
