[0041] Reference Figures 1-5The utility model discloses an embodiment shows a kind of leather cutting device, including base 1, processing table 2, laser cutting mechanism 3, first carrying mechanism 4a and second carrying mechanism 4b, the base 1 includes two parallelly arranged and along the longitudinal beam 11 of first direction X setting, two longitudinal beams 11 between being equipped with belt conveyor 12;The processing table 2 is movably arranged on two longitudinal beams 11 along first direction X, the processing table 2 includes multiple support rods 21 arranged at intervals, and hollow gap 22 is equipped between adjacent support rods 21;The laser cutting mechanism 3 includes laser cutting head 31 and gantry frame 32, the gantry frame 32 is set on the base 1, and the laser cutting head 31 is movably arranged on the gantry frame 32 along second direction Y and third direction Z;First direction X and second direction Y are mutually perpendicular direction on horizontal plane, and third direction Z is vertical;First carrying mechanism 4a and second carrying mechanism 4b are set on the side of base 1, in first direction X, first carrying mechanism 4a and second carrying mechanism 4b are located at two ends of laser cutting mechanism 3 respectively;First carrying mechanism 4a is used to move leather to the processing table 2, and second carrying mechanism 4b is used to remove leather on the processing table 2.

[0042] Specifically, in some embodiments, as shown in Figure 1 And 2 The first carrying mechanism 4a is placed on the processing table 2, and the processing table 2 moves along the first direction X, while the laser cutting head 31 on the laser cutting mechanism 3 moves along the second direction Y and the third direction Z, realizing cutting of the leather on the processing table 2. Figure 4 As shown in During cutting, the cuttings fall through the hollow gap 22 on the processing table 2 onto the belt conveyor 12, and when the processing table 2 passes the laser cutting mechanism 3, the cutting work is completed, and the second carrying mechanism 4b removes the leather on the processing table 2.

[0043] Among them, the leather cutting device integrates the first carrying mechanism 4a and the second carrying mechanism 4b, which realizes the automatic processing of leather feeding and discharging, greatly reduces manual intervention, and significantly improves the overall efficiency of the production line. At the same time, the automatic movement of the processing table 2 on the longitudinal beam 11 cooperates with the multi-dimensional flexible operation of the laser cutting head 31, ensuring efficient and continuous cutting operation.
