The main innovation lies in the change in the driving mode of the winding assembly.

[0027] Specifically,

Among them, each box 3 is connected to the workbench 1 by sliding forward and backward through a guide rail slider structure, and the workbench 1 is also provided with two driving assemblies for driving the two boxes 3 to slide forward and backward respectively. A machine head 4 is provided on the front side of the two boxes 3, and the machine head 4 includes a rotating shaft 4a arranged horizontally on the box 3. A strip-shaped clearance groove 1a is vertically penetrated on the workbench 1, and the length of the clearance groove 1a extends forward and backward. There are two clearance grooves 1a and they are respectively arranged opposite to the two boxes 3. A connecting plate 5 is vertically penetrated in the two clearance grooves 1a. The two winding motors 2 are both located below the workbench 1 and are respectively fixed to the lower ends of the two connecting plates 5. The upper ends of the two connecting plates 5 are respectively fixed to the box 3, and the two winding motors 2 drive the two rotating shafts 4a to rotate respectively through the synchronous belt 11 transmission structure.

[0029] The two boxes 3 are driven to move by two driving components respectively, so that the two heads 4 can move independently for winding, so as to realize independent action of two workstations to meet different working conditions, and the practicability is good.

[0030] At the same time, placing the winding motor 2 for driving the machine head 4 under the worktable 1 can move the machine head 4 downward, move the center of gravity of the winding assembly downward as a whole, make the overall sliding of the winding assembly more stable, and improve the winding quality and accuracy.
