[0018] Embodiment

[0019] As Figures 1-3 shown, the present utility model provides a production device for a lightweight tire zero-degree belt layer, including a forming machine and a winding roller 13; the forming machine includes a die 1 and a screw feeder 2, a forming cavity is arranged in the die 1, one end of the die 1 away from the winding roller 13 is provided with a steel wire 3 inlet, the steel wire 3 inlet is communicated with the forming cavity, one end of the die 1 close to the winding roller 13 is provided with a discharge port 16 corresponding to the steel wire 3 inlet, the discharge port 16 is communicated with the forming cavity, and the forming cavity is communicated with the discharge pipe of the screw feeder 2;

[0020] A packaging assembly is arranged between the forming machine and the winding roller 13, the packaging assembly includes a bracket 18, and a packaging tape roller 7 and a guide roller 9 are arranged on the bracket 18.

[0021] There are two groups of the steel wire inlets, the two groups of steel wire 3 inlets are located on the same horizontal line, each group of steel wire inlets includes a plurality of steel wire holes 15, and the plurality of steel wire holes 15 are arranged horizontally. This setting can produce two zero-degree belt layers simultaneously, improving the production efficiency.

[0022] The number of the steel wire holes 15 of the steel wire inlet is 9, 11 or 13. On the premise of not affecting its function, the weight is reduced to achieve lightweight.

[0023] A pressure roller group is further arranged on the bracket 18, the pressure roller group includes a cooperating upper pressure roller 6 and a lower pressure roller 5, the lower pressure roller 5 is connected with a motor one (not shown in the subfigure), the upper pressure roller 6 is connected with a vertical telescopic rod 17, the vertical telescopic rod is an electric push rod or a hydraulic cylinder, one end of the upper pressure roller is rotatably connected with a rotating block (not shown in the attached drawing) through a bearing, and the rotating block is fixedly connected with the telescopic end of the vertical telescopic rod. This setting can level the formed zero-degree belt layer, making it fit better with the packaging film subsequently.

[0024] Both ends of the winding roller 13 are respectively rotatably connected with a column 10 through bearings, the lower end of the column 10 is fixed on the ground, and one end of the winding roller 13 is connected with a motor two 12, and the motor two 12 is fixed on the corresponding column 10.
