[0038] The clamping assembly also includes a moving cross bar 111 and a clamping plate 113 located at the discharge end of the conveyor belt 103 and capable of synchronously moving with the moving beam 105. The conveyor belt 103 also passes through the gap between the clamping plate 113 and the moving cross bar 111 and can be clamped by the clamping plate 113 and the moving cross bar 111 when the clamping plate 113 approaches the moving cross bar 111.

[0039] According to the above structure provided in the present embodiment, in the feeding device of the leather fabric punching machine provided in the present embodiment, the conveyor belt 103 wound on the guide roller 102 and used for feeding does not have power itself. When working, the first pressure beam 104 in the clamping assembly is driven by the first cylinder 106 to approach the moving beam 105 to clamp the conveyor belt 103 and the leather fabric loaded thereon. At the same time, the clamping plate 113 also approaches the moving cross bar 111 and clamps the conveyor belt 103 and the leather fabric loaded thereon. After that, the conveyor belt 103 can The moving beam 105 moves and moves forward for a certain distance to smoothly deliver the leather fabric between the first pressure beam 104 and the clamping plate 113 to the target punching station; during the punching process of the leather fabric, the first pressure beam 104 can be driven by the first cylinder 106 to move away from the moving beam 105 and release the conveyor belt 103, and synchronously, the clamping plate 113 also moves away from the moving cross bar 111, and then the moving beam 105 and the first pressure beam 104 as well as the clamping plate 113 and the moving cross bar 111 can be moved back to the initial position and used for the next feeding. In this way, the feeding device of the leather fabric punching machine provided in this embodiment, the time for the moving beam 105 to return to the initial position can coincide with the punching time of the leather fabric, therefore, the feeding device of the leather fabric punching machine provided in this embodiment can achieve a higher feeding efficiency, and the leather fabric can always be kept flat during the conveying process, which is far superior to the prior art.
