Description

Technical Field

[0001] The invention relates to the technical field of shoe processing equipment, and in particular to a shoe upper punching machine. Background Art

[0002] As is known to all, most shoes have shoelaces, which are used to keep the shoes stably worn on the feet. When the shoes are produced, the shoe uppers are processed into shoelace holes by a punching machine.

[0003] Traditional punching machines can only punch holes in shoe uppers, do not have the ability to adjust the hole spacing, and are unable to adapt to the processing of shoelace holes for shoe uppers of various specifications.

[0004] The Chinese patent authorization announcement number is CN212193460 U, which discloses a multifunctional punching machine, including a frame, a working panel is provided on the frame, a support frame is provided on the working panel, a workbench is provided at the bottom of the support frame, a pad is installed on the workbench, a lifting mechanism for punching positioning is provided above the pad, a wire rope fixing part is provided on the lower end surface of the lifting plate of the lifting mechanism, the wire rope fixing part is connected to the foot pedal through a wire rope, a punching cylinder is installed on the top of the support frame, the end of the piston rod of the punching cylinder passes through the support frame and cooperates with the sleeve, and the piston rod of the punching cylinder is pressed against the lifting plate, and a guide rail is installed on the guide rail. A plurality of punching assemblies are provided on the guide rail, a first spring is provided between each two adjacent punching assemblies, a fixing plate for fixing the punching assembly is provided at both ends of the guide rail, and a second spring is provided between the fixing plate and the punching assembly. Although this punching machine can adjust the hole spacing between the punches to adapt to the punching of shoe uppers of different specifications, it still has the following defects: 1. Since the punching assembly can only punch holes in the same position when punching the shoe upper of the same specification, long-term use will cause the punch head to punch holes in the same position, which will not only damage the backing plate (stamping plate), resulting in a short service life of the backing plate (stamping plate), but also cause problems such as untidy punching of the shoe upper and many burrs.

[0005] 2. Since the punching assembly is installed on the machine through fasteners, when the punching spacing needs to be adjusted, the punch can only be adjusted on the equipment. If it is removed by loosening the fasteners, the efficiency is low. If the worker makes an operating error during the operation (such as accidentally stepping on the power button), it will bring great safety hazards and is unsafe to use. Summary of the Invention
