[0027] Working principle:

[0028] Auxiliary fixing process of cutting devices for leather goods production:

[0029] The operator places the leather goods under the two pressing blocks 307 on the surface of the workbench 4, connects the external power supply of the third motor 301, starts the output shaft of the third motor 301 to rotate and drives the worm 302 to rotate, the worm 302 drives the worm wheel 303 to rotate and drives the two gears 304 to rotate, the two gears 304 are meshed with each other and rotate in opposite directions, the gear 304 drives the rotating rod 305 to rotate, the rotating rod 305 drives the sliding rod 306 to move downward, the sliding rod 306 drives the pressing block 307 to move synchronously, and the pressing block 307 stops rotating after the pressing block 307 is pressed against the surface of the leather goods, so as to facilitate the subsequent cutting of the leather goods.

[0030] Auxiliary cutting process of cutting device for leather goods production:

[0031] The external power supply of the first motor 201 is connected, and the output shaft of the first motor 201 is started to rotate to drive the first threaded rod 203 to rotate, and the first threaded rod 203 drives the second shell 205 and the cutting blade 11 to move along the X axis. The external power supply of the second motor 204 is connected, and the output shaft of the second motor 204 is started to rotate to drive the second threaded rod 206 to rotate, and the second threaded rod 206 rotates to drive the thread block 207 and the cutting blade 11 to move along the Y axis.

[0032] The recycling process of scraps from cutting devices used in leather goods production:

[0033] Since waste scraps are generated during the cutting process of leather goods, before cutting the leather goods, the external power supply of the vacuum cleaner 6 is turned on, the suction end of the vacuum cleaner 6 is started to suck air, and the waste scraps generated on the surface of the workbench 4 are absorbed through the wind box 7 to complete the waste scrap recovery process of the cutting device for leather goods production.
