The working principle is as follows: when the leather carving soft package polishing device is in an initial state, as shown in fig. 1-4, a leather carving soft package to be polished is placed on the central plate 201 in the middle of the clamping mechanism 2, the reciprocating mechanism 5 is started, the second servo motor 502 drives the chain 504 to move through the chain wheel 503, and then the moving plate 505 moves along the first guide rail 501 through the cooperation among the chain 504, the sliding block 507 and the vertical rod 506, so that the clamping mechanism 2 is driven to move along the first guide rail 501;

when the clamping mechanism 2 moves, the worm wheel 601, the worm 603 and the first gear 604 are driven to synchronously move, the worm 603 is driven to rotate under the meshing action of the first gear 604 and the first rack 605 fixed on the rack 1, the worm 603 and the worm wheel 601 are driven to drive the round sleeve 2052 to clockwise rotate, and through the transmission of the first swing rod 2053 and the second swing rod 2054, the sliding rods 203 can synchronously slide close to the central plate 201 at equal intervals, so that the four right-angle plates 204 clamp the leather carving soft packages placed on the central plate 201 centrally, and due to the characteristics of the worm wheel 601 and the worm 603, the first adjusting mechanism 6 can be self-locked after clamping the leather carving soft packages;

the leather carving soft package continuously moves along the first guide rail 501 along with the clamping mechanism 2 and is completely polished by the first polishing roller 3;

when the leather carving soft package is positioned between the two polishing rollers 3, the first limiting rod 807 of the first locking mechanism 8 drives the sliding bolt 805 to retreat from the fan-shaped groove 801 against the elasticity of the first pressure spring under the action of the first wedge-shaped block 804, and when the second gear 701 of the second adjusting mechanism 7 is just meshed with the second gear 702, the clamping mechanism 2 and the leather carving soft package are driven to rotate clockwise by 90 degrees to convert the polishing direction of the leather carving soft package, the limiting block 802 synchronously moves from one end of the fan-shaped groove 801 to the other end, then the second gear 701 is separated from the second gear 702, meanwhile, the first limiting rod 807 slides to the inclined surface part of the first wedge-shaped block 804, the sliding bolt 805 slides into the fan-shaped groove 801 again under the elasticity of the first pressure spring, and the limiting block 802 is fixed in the fan-shaped groove 801, so that the clamping mechanism 2 and the leather carving soft package cannot rotate any more; the leather carving soft bag continuously moves to pass through the second polishing roller 3 for polishing;

then the sliding block 507 of the reciprocating mechanism 5 needs to return along with the turning of the chain 504, the sliding block 507 slides downwards in the vertical rod 506 during turning, then the vertical rod 506 and the moving plate 505 move reversely along the first guide rail 501, the leather carving soft bag starts to move reversely, the leather carving soft bag is polished by the second polishing roller 3, and the polishing direction is opposite to that of the coming leather carving soft bag;

when the leather carving soft package is positioned between the two polishing rollers 3 again, the first locking mechanism 8 and the second adjusting mechanism 7 are triggered reversely at the same time, so that the clamping mechanism 2 and the leather carving soft package rotate 90 degrees anticlockwise and then pass through the first polishing roller 3, and the polishing direction is opposite to that of the coming leather carving soft package;

when the leather carving soft bag returns to the initial position, the first adjusting mechanism 6 is triggered reversely, so that the circular sleeve 2052 rotates anticlockwise, the sliding rods 203 of the clamping mechanism 2 synchronously slide away from the central plate 201 at equal intervals, and the polished leather carving soft bag is loosened;

next, the hydraulic cylinder 15 starts to extend to drive the pushing assembly 11 to move, first, in a first stroke, the second locking mechanism 13 is in a locked state, the sliding block 1301 is stopped at one side of the moving seat 1211 under the action of the tension spring, so that the pushing assembly 11 does not push the moving seat 1211 to move when moving, the third rack 1217 on the pushing assembly 11 moves along the second guide rail 10, and is engaged with the third gear 1213 of the folding linkage unit 121 to drive the central shaft 1212 and the fourth gear 1214 to rotate, the fourth gear 1214 is engaged with the two fourth racks 1215, the two fourth racks 1215 drive the lifting linkage unit 122 and the two clamps 9 to approach each other through the L-shaped rod 1216, so as to achieve the folding of the two clamps 9, when the two clamps 9 are folded, the edge of the soft package bottom plate of the leather carving on the clamping mechanism 2 that has been released is clamped between the L-shaped plate 901 and the movable plate 902, the movable plate 902 presses the movable plate 902 against the soft package bottom plate of the leather carving, at this time, the third wedge 1211 moving block the sliding block 1301, and the sliding block 1102;

in the second stroke, the first push block 1102 is blocked by the movable seat 1211 to drive the linkage assembly 12 to move, the second limiting rod 1223 moves along the slope of the guide rod 1224, the inner rod 1222 is retracted towards the inner rod 1221, and the clamp 9 and the leather carving soft package are driven to move horizontally and simultaneously are lifted to be higher than the top of the right-angle plate 204;

in the third stroke, the first push block 1102 pushes the linkage assembly 12 and the clamp 9 to move continuously, the leather carving soft package is completely removed from the upper side of the clamping mechanism 2, when the second limiting rod 1223 moves to the inclined surface at the other end of the guide rod 1224, the inner rod 1222 starts to slide downwards from the inner part of the outer rod 1221, and the clamp 9 falls to the height before the leather carving soft package is clamped;

in the fourth stroke, firstly, the third locking mechanism 14 is in a locking state, the moving seat 1211 is blocked, the hydraulic cylinder 15 starts to contract to drive the pushing assembly 11 to return, the third rack 1217 moves reversely along the second guide rail 10 to be meshed and matched with the third gear 1213, the lifting linkage unit 122 and the two clamps 9 are separated from each other through the central shaft 1212, the fourth gear 1214 and the two fourth racks 1215, the separated distance is equal to the distance before the folding, the leather carving soft package is released and placed on the platform or the conveying belt, the third wedge 1304 moving along with the third rack 1217 unlocks the third locking mechanism 14, and the second pushing block 1103 is just blocked and connected with the moving seat 1211;

in the fifth stroke, the second pushing block 1103 abuts against the moving seat 1211 to drive the linkage assembly 12 and the two clamps 9 to move to the first stroke initial position.
