[0006] Preferred technical solution one: the guiding device includes a vertical guiding device and a transverse guiding device fixed on the frame, the vertical guiding device is used to vertically guide the materials in the material rolls in the material trays distributed at different heights of the frame to the same height; the transverse guiding device is used to guide the ropes at the same height in the transverse direction.

[0007] Preferred technical solution 2: The guide device includes a fixing seat fixed on the frame and a guide channel formed on the fixing seat, and the number of the guide channels is consistent with the number of materials passing through the group of guide devices.

[0008] Preferred technical solution three: The guide channels are of different types according to the different specifications of the ropes.

[0009] Preferred technical solution four: universal wheels are installed on the bottom side of the frame.

[0010] Preferred technical solution five: A detection sensor is installed on a fixed seat in a group of corresponding guide devices on the frame close to each group of material trays, which is used to detect whether there is material passing through the corresponding guide channel.

[0011] The above structure enables this solution to have the following beneficial effects:

[0012] 1. The frame is fixed on the ground with universal wheels and can also be moved;

[0013] 2. The bottom of the material tray is rotated by flange and vertical rod, which effectively prevents the material from being torn off;

[0014] 3. The direction of the wire material can be changed by the round rod to prevent the material from being mixed together due to the large amount of material;
