A motorcycle dust cover manufacturing machine according to any one of claims 1-5, characterized in that: A secondary heat sealing device is provided between the longitudinal sealing device and the cutting device to perform a secondary heat sealing of the material after longitudinal sealing. The secondary heat sealing device includes a heat sealing frame and a welding assembly set on the heat sealing frame. The welding assembly includes a welding frame, a welding seat set on the welding frame, a welding cylinder set on the welding seat, and a welding head set at the output end of the welding cylinder. The welding cylinder is used to drive the welding head to move axially up and down.

7. A motorcycle dust cover manufacturing machine according to claim 6, characterized in that: The welding frame is provided with sliders at both ends corresponding to the heat sealing frame, which can slide laterally along the heat sealing frame. The welding frame is provided with a guide shaft, and the welding seat is sleeved outside the guide shaft and can slide longitudinally along the guide shaft.

8. A motorcycle dust cover manufacturing machine according to claim 6, characterized in that: Both sides of the secondary heat sealing device are provided with sealing line fine adjustment mechanisms. Each sealing line fine adjustment mechanism includes a lifting frame, a lifting seat that is slidably set on the lifting frame, a lifting roller that is rotatably set on the lifting seat, and a roller height adjustment mechanism for adjusting the axial height of the lifting roller.

9. A motorcycle dust cover manufacturing machine according to claim 8, characterized in that: The roller height adjustment mechanism includes screws at both ends of the lifting seat and an adjusting rod passing through the lifting frame. The lifting seat is threaded to both ends of the screws. The adjusting rod passes through the lifting frame and is equipped with an adjusting handwheel. The adjusting rod and the screws are driven by a helical gear. By rotating the adjusting handwheel, the axial height of the lifting roller on the lifting frame is adjusted.

10. A motorcycle dust cover manufacturing machine according to any one of claims 1-5, characterized in that: The material unwinding device includes a feeding unwinding assembly, a discharging unwinding assembly, and a feeding conveyor frame. The feeding unwinding assembly is used to convey the upper layer of material to the upper elastic band pressing assembly via the feeding conveyor frame. The discharging unwinding assembly is used to convey the lower layer of material to the lower elastic band pressing assembly. Both the feeding and discharging unwinding assemblies include an unwinding seat, an unwinding frame mounted on the unwinding seat, an unwinding drive motor, and an unwinding lifting cylinder. One end of the unwinding frame is hinged to the unwinding seat via a hinge shaft, and the other end is provided with an unwinding roller. The unwinding drive motor is used to drive the unwinding roller to rotate and unwind. The unwinding lifting cylinder is used to drive the unwinding frame to rotate along the hinge shaft, thereby raising or lowering the unwinding roller.
