Specifically, an L-shaped pushing plate 14 is fixed on the fixing ring 1305, and the leather body 5 on the machine body 2 is centered and positioned by the pushing of the L-shaped pushing plate 14.

Specifically, a plurality of pushing pins 16 are fixed on the opposite side walls of the two sliding plates 10, two ends of each extrusion pipe 1312 are magnetically connected with the sliding plates 10, when longitudinal wrinkles are protruded on the leather, it is difficult to flatten the leather by the extrusion of the sleeve 1310, the sleeve 1310 is further driven to move upwards continuously, the sleeve 1310 is pressed against each pushing pin 16 on the sliding plate 10 along with the movement of the sleeve 1310, the sleeve 1310 is pushed to slide longitudinally on the machine body 2 by each pushing pin 16, the longitudinal wrinkles are flattened on the leather by the longitudinal sliding of the sleeve 1310, and after flattening, under the action of magnetic force, the sleeve 1310 is pressed against the sliding plate 10 and pressed against the sliding plate 10.

The working principle is as follows: when the leather cutting machine works, firstly, when the leather is cut, one end of a leather body 5 on a first rotating shaft 4 passes through a position between a first squeezing roller 602 and a second squeezing roller 608, the second squeezing roller 608 on a U-shaped plate 606 extrudes and fixes the leather body 5 through pushing of a first spring 607 on a first sliding rod 605, a first motor 604 is started to drive the first squeezing roller 602 on a second rotating shaft 603 to rotate, the leather body 5 between the first squeezing roller 602 and the second squeezing roller 608 is driven on a machine body 2 through rotation of the first squeezing roller 602, a second motor 705 is started to drive a threaded rod to rotate, under the meshing transmission of the threaded rod and a threaded sleeve 702 and the guiding action of a first fixing rod 706 and a second sliding rod 707, the square plate 704 moves close to the machine body 2, and a cutting knife 8 on the square plate 704 moves to the leather body 5 placed on the machine body 2, through the horizontal sliding of the two sliding plates 701 and the vertical sliding of the cutting knife 8 on the square plate 704, the cutting knife 8 can rapidly cut each position of the leather body 5 on the machine body 2, so that the leather cutting operation is facilitated, and the cutting efficiency is improved;

then, in the process that the square plate 704 moves towards the machine body 2, the sliding plate 10 is driven to synchronously move downwards by the movement of the square plate 704, one end of the third rotating shaft 1104 on the sliding plate 10 is abutted against the upper end surface of the positioning plate 1107, the third rotating shaft 1104 is positioned by the positioning plate 1107, the circular plate 1103 slides on the fourth sliding rod 1102 along with the movement of the square plate 704, so that the third pressing roller 1106 on the third rotating shaft 1104 is pressed against the leather body 5 on the machine body 2, the pressing operation of the leather body 5 placed on the machine body 2 in the cutting process is formed, the leather is prevented from being forced to slide in the cutting process, the cutting is not in place, the cutting quality is improved, meanwhile, in the process that the square plate 704 moves towards the machine body 2, one end of the transmission pin 1307 is abutted against the upper end surface of the positioning plate 1107 along with the sliding of the square plate 704, and the sliding plate 10 continues to move, the driving plate 1308 on the sliding plate 10 synchronously moves downwards, so that the inclined groove 1309 on the driving plate 1308 interacts with the driving pin 1307 on the fourth rotating shaft 1306, the driving pin 1307 is pushed to slide on the inclined groove 1309, the fourth rotating shaft 1306 on the driving pin 1307 is driven to continuously move towards the machine body 2 in the sliding process of the driving pin 1307, the sleeve 1310 outside the fourth rotating shaft 1306 is further extruded with the leather body 5 on the machine body 2 and synchronously rotates, when the crease bulge 1310 exists on the leather in the sleeve moving process, the sleeve 1310 is pushed to move away from the machine body 2 under the action of force, the pushing rod 1311 slides inside the extruding pipe 1312 in the sleeve moving process, the extruding spring generates elastic force, the pushing rod 1311 is pushed to reset the sleeve 1310 through the elastic force of the extruding spring, and the smearing operation of the crease bulge is further realized, when longitudinal fold bulges exist on the leather, the sleeve 1310 is difficult to float through extrusion, the sleeve 1310 is further driven to continuously move upwards, the sleeve 1310 is pressed against each pushing pin 16 on the sliding plate 10 along with the movement of the sleeve 1310, the sleeve 1310 is pushed to longitudinally slide on the machine body 2 through each pushing pin 16, the longitudinal fold bulges on the leather are floated through the longitudinal sliding of the sleeve 1310 on the leather, the sleeve 1310 leans against the sliding plate 10 and presses against the sliding plate 10 under the action of magnetic force after the floating is finished, and the floating operation of the leather to be cut in the leather cutting operation process can be formed in the whole floating operation process, so that the error in the cutting process caused by the fold bulges is avoided, and the manufacturing quality of the luggage is further improved;

finally, in the process that the sliding plate 10 moves towards the machine body 2, along with the sliding of the sliding plate 10, one end of the sliding plate 10 abuts against the first inclined surface 1505 on the pushing plate 1504, under the guiding action of the force transmission and the round rod 1502, the pushing plate 1504 is pushed to move towards the fixed plate 1501, in the process that the pushing plate 1504 moves, the second inclined surface 1506 on the pushing plate 1504 abuts against one end of the U-shaped plate 606, the U-shaped plate 606 is pushed to slide on the first sliding rod 605 under the action of the force, along with the sliding of the U-shaped plate 606, the second extrusion roller 608 on the U-shaped plate 606 no longer abuts against the leather body 5, the phenomenon that when the leather is leveled is fixed by the first extrusion roller 602 and the second extrusion roller 608, the second reset protrusion of the leveled leather is easily caused is avoided, and the operation of the leveling mechanism 13 is further facilitated.
