[0002] In the lithium battery production process, the slurry mixing process involves mixing and stirring various positive and negative electrode materials until they reach a viscous consistency, and then uniformly coating them onto the surface of copper and aluminum foil materials. Slurry mixing equipment is usually numerous and large in size, occupying a large area and not conducive to saving space. Therefore, in actual production, slurry mixing equipment is usually stacked on steel platforms. Slurry mixing equipment located at high positions usually uses material hoists to lift the positive and negative electrode materials used in the lithium battery production process to the high position of the slurry mixing steel platform for use.

They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0026] like Figures 1 to 2 The diagram shows a preferred embodiment of a material hoist safety control system, which includes: a hoist 1, a lower roller conveyor line 2, a shape detection mechanism 3, an upper roller conveyor line 4, a lower safety net structure 5, and an upper safety net structure 6.

[0027] The output end of the lower roller conveyor line 2 is located at the inlet 11 of the elevator 1, and the input end of the upper roller conveyor line 4 is located at the outlet 12 of the elevator 1; the lower safety net structure 5 is located at the input end of the lower roller conveyor line 2, the upper safety net structure 6 is located at the output end of the upper roller conveyor line 4, and the shape detection mechanism 3 is located on the lower roller conveyor line 2.

[0028] In actual use, the user uses a forklift to pick up material 101, opens the lower safety enclosure structure 5, and places material 101 into the lower roller conveyor line 2. The lower roller conveyor line 2 then transports material 101 towards the elevator 1. When material 101 passes the shape detection mechanism 3, the mechanism detects whether the dimensions of material 101 exceed the capacity of the elevator 1. If the dimensions of material 101 are larger than the capacity of the elevator 1, the lower roller conveyor line 2 stops operating, and the user removes material 101 using a forklift. If the dimensions of material 101 are less than or equal to the capacity of the elevator 1, the lower roller conveyor line 2 continues operating, feeding material 101 into the elevator 1. At this time, the lower safety enclosure structure 5 is closed, and the user is not allowed to approach the work area. The elevator 1 transports material 101 upwards, and then material 101 is output through the upper roller conveyor line 4. When it is output to the output end of the upper roller conveyor line 4, the user opens the upper safety net structure 6 and removes material 101 by forklift. After material 101 is removed, the upper safety net structure 6 is closed, and the material 101 transportation process ends.

[0029] Furthermore, when the device is not in use, the lower safety net structure 5 and the upper safety net structure 6 are always closed, preventing users from entering the area of ​​the device when it is not in use, thus protecting user safety and improving production safety.

[0030] Furthermore, the inlet 11 and outlet 12 of the hoist 1 can be located at different heights on the same side, different heights on opposite sides, or different heights on adjacent sides of the hoist 1.
