[0059] As shown in Figure 1 ; the carrier block 11 is provided with a pushing mechanism 2, the pushing mechanism 2 comprises:

[0060] The bracket 23 is fixed to the outer wall of the carrier block 11, the upper side of the bracket 23 is provided with a mounting plate 21, the top of the mounting plate 21 is fixedly provided with an electric push rod 22, the push rod of the electric push rod 22 is movably penetrated through the mounting plate 21 and is fixedly connected with the top of the bracket 23;

[0061] In actual use, the bracket 23 is lowered by the electric push rod 22, so as to drive the carrier block 11 to descend, thereby realizing the descending of the punching head 12 for punching opening;

[0062] Further, the top of the mounting plate 21 is provided with mounting holes 25 at the four corners, the arrangement of the mounting holes 25 facilitates the installation and fixation of the whole device.

[0064] The implementation principle of the leather belt stamping device is as follows: the bracket 23 is pushed down by the electric push rod 22, so that the carrier block 11 is driven to descend, and then the stamping head 12 is driven to descend to stamp an opening. At this time, the tensioning mechanism 3 is lowered. When the leather belt is stamped, the compression roller 36 is in line contact with the leather belt. With continuous descent, the compression roller 36 applies pressure to both sides of the leather belt. With the continuous descent of the carrier block 11, the connecting plate 34 rotates at this time, so that the compression roller 36 moves to both sides, so that in the process of applying pressure to the leather belt, the leather belt has an outward tension on both sides, so that the flatness of the leather belt can be ensured, and the wrinkling or bending of the leather belt can be avoided, so that the accuracy of the leather belt stamping opening can be ensured. When the compression roller 36 applies pressure to the leather belt, the inner wall of the circular plate 37 is provided with a circular arc chamfer at this time, so that the slightly deviated leather belt can be corrected before pressure is applied. The leather belt will accurately enter the two circular plates 37 and the compression roller 36 along the circular arc chamfer, so that the position of the leather belt can be ensured. In the process of applying pressure to the leather belt by the compression roller 36, the connecting plate 34 rotates, so that the push plate 38 rotates. The part on the top of the push plate 38 is lifted compared with the carrier block 11, so that the connecting frame 43 is lifted. At this time, the connecting frame 43 drives the horizontal plate 42 to lift, so that the push rod 41 is lifted, so that the waste can enter the cavity of the stamping head 12 when the stamping head 12 punches the leather belt. After the punching is completed, the stamping head 12 is lifted, so that the compression roller 36 is released. At this time, the pushing force of the push plate 38 on the connecting frame 43 is released, so that the connecting frame 43 is lowered under the back pulling force of the spring 44, so that the connecting frame 43 drives the push rod 41 to descend and pushes out the waste in the stamping head 12, so that the waste is automatically removed. At the same time, the connecting frame 43 descends to push the push plate 38 to reset, so that the compression roller 36 is reset, and the compression roller 36 is convenient to use again.
