A flip-over assembly for automatic hat-making production line equipment includes an installation seat, a flip-over component, two groups of driving components, a translation component, and an angle adjustment component. The flip-over component is correspondingly installed at a top end of the installation seat. The two groups of driving components are matchingly installed on both side walls of the installation seat. Output ends of the driving components are in a transmission connection with the flip-over component. The angle adjustment component is installed on a lower surface of the installation seat. The translation component is matchingly installed on a lower surface of the angle adjustment component. The flip-over assembly can collect cloth using a left side plate and a right side plate, and can clamp and open the cloth and perform double-needle sewing on the cloth and subsequent cloth opening, which can be controlled by the operator.

A precise positioning mechanism for automatic hat-making production line equipment includes a rack, an installation seat, a jacking device, a positioning column, a material pickup and discharging platform, a support column, a guide rod, and an infrared ranging sensor. The material pickup and discharging platform is located at a top of one side of the rack. The installation seat is arranged on both sides of a bottom of the material pickup and discharging platform separately through bolts. The jacking device is arranged at a bottom of the installation seat of the material pickup and discharging platform through bolts. The positioning column corresponding to a position of the jacking device is inserted into both sides of a top of the material pickup and discharging platform separately. An output end of the jacking device and a bottom of the positioning column are connected through bolts.
