Finally, by moving the rotating handle 442, the distance between the tip of the skinning knife 43 and the skinning roller 21 can be adjusted to control the thickness of the allogeneic / xenogeneic skin slice.

[0066] In this embodiment, through actual operational measurement, the position of the rotating handle 442 is adjusted and the thickness of the split allogeneic / xenogeneic skin graft is marked on the outside of the arc of the scale marking hole 6 on the second shell 15, so that the split thickness can be adjusted according to the mark during the subsequent splitting process of the allogeneic / xenogeneic skin graft.

[0067] <Operation process of the splitting machine suitable for allogeneic / heterogeneous leather processing in the embodiment>

[0068] Use the splitting machine suitable for processing allogeneic / heterogeneous leather provided in <Example>, take a large allogeneic / heterogeneous leather piece to be split, place one end of it on the fixing protrusion inside the side groove of the splitting roller, and then use a fixing mechanism in conjunction with nuts and bolts to clamp it between the fixing protrusion and the fixing mechanism, and the remaining part is placed on the threaded shaft surface of the splitting roller.

[0069] Then, by operating the control panel, the peeling roller is adjusted according to the instructions. Figure 8 Before splitting, the allogeneic / xenogeneic skin pieces on the splitting roller will be pressed by the skin pressing roller, and then split and separated by the splitting knife with horizontal reciprocating linear motion, and the allogeneic / xenogeneic skin pieces left on the splitting roller are the allogeneic / xenogeneic skin pieces after splitting.

[0070] During the splitting process, the shortest distance between the skin splitting roller and the skin pressing roller is 0.05 cm. If the thickness of the allogeneic / xenogeneic skin graft is greater than 0.05 cm, the skin pressing roller will press the allogeneic / xenogeneic skin graft onto the skin splitting roller through the tensioning action of the resetting elements at both ends of the roller.

[0071] If the thickness of the split allogeneic / xenogeneic skin piece is to be adjusted, the handle can be rotated to adjust the angle between the rotating rod and the connecting rod, thereby changing the distance between the blade of the splitting knife and the splitting roller, thereby adjusting the thickness of the split allogeneic / xenogeneic skin piece.

The long strip fixing plate is fastened to the fixing protrusion through a screw and a nut, and one end of the allogeneic / heterogeneous skin piece is clamped between the long strip fixing plate and the fixing protrusion. The long strip fixing plate is located in the side groove. This arrangement allows the allogeneic / heterogeneous skin piece to be fixed on the skin splitting roller and is not easy to fall off during the entire splitting process.

[0076] Furthermore, the rotating mechanism further comprises a skin pressing roller, which is horizontally placed between the left partition and the right partition, and is used to press the foreign body / heterogeneous skin piece against the skin splitting roller during the rotation of the skin splitting roller so as to be split by the splitting mechanism. This arrangement allows the foreign body / heterogeneous skin piece to be pressed against the skin splitting roller.

[0077] Furthermore, the surface of the skin splitting roller has threaded protrusions for enhancing the friction between the skin and the allogeneic / xenogeneic skin graft during its rotation, so that it is not easy to fall off or slide out of place. The surface of the skin pressing roller has threaded protrusions for better pressing the allogeneic / xenogeneic skin graft during its rotation, so that it is not easy to slide out of place.

[0078] Furthermore, the left partition and the right partition are symmetrically provided with elliptical through holes of the same size, and the two ends of the skin-pressing roller respectively pass through the elliptical through holes on the left partition and the right partition so that the skin-pressing roller is placed horizontally between the left partition and the right partition, and can slide up and down with the elliptical through holes as sliding tracks. The left side of the elliptical through holes of the left partition and the right side of the elliptical through holes of the right partition are partially covered by limited blocks, and the limited blocks are used to support the two ends of the skin-pressing roller so that the skin-pressing roller is not in direct contact with the skin-splitting roller. In the vertical direction, the two ends of the skin-pressing roller are respectively connected to the left partition and the right partition through a reset element. The direction of the action force of the reset element is to pull the skin-pressing roller closer to the skin-splitting roller. When the thickness of the allogeneic / xenogeneic skin graft exceeds the minimum distance between the skin-pressing roller and the skin-splitting roller, the reset element is used to tighten the skin-pressing roller so that the allogeneic / xenogeneic skin graft is firmly pressed against the skin-splitting roller. Such an arrangement enables the allogeneic / xenogeneic skin piece to be closely attached to the skin splitting roller before splitting, making splitting easier.

[0079] Furthermore, the chopping mechanism includes: a chopping knife, which is used to chop the foreign / heterogeneous skin piece driven by the rotating mechanism, and the blade thereof faces the rotating mechanism; and a second driving unit, which is arranged on the machine body and is used to provide power for the chopping process of the chopping knife. The chopping mechanism also includes: a connecting rod, which passes through the left partition and the right partition horizontally and reciprocatingly, is connected to the second driving unit and is powered by it to perform horizontal and reciprocating linear movements; a knife holder, which is mounted on the connecting rod and performs horizontal reciprocating linear movements driven by the connecting rod, wherein the chopping knife is fixed on the knife holder and is driven by the knife holder to perform horizontal reciprocating linear movements together to chop the foreign / heterogeneous skin piece driven by the rotating mechanism. Such a configuration makes the chopping machine suitable for foreign / heterogeneous skin processing have a high degree of automation and chopping efficiency.

[0080] Furthermore, the left and right partitions are symmetrically provided with arc-shaped through holes of the same size, and the chopping mechanism also includes a rotating rod, which is laterally provided through the arc-shaped through hole of the left partition, the tool holder and the arc-shaped through hole of the right partition in turn. In the vertical direction, when the rotating rod slides in the arc-shaped through hole, the center of the arc-shaped sliding trajectory of the center of the circle of the rotating rod is the center of the circle of the connecting rod, and the rotating rod drives the tool holder to rotate around the connecting rod in the vertical direction by sliding its two ends in the arc-shaped through holes. The rotating rod and the tool holder are connected by the matching engagement of the shaft protrusion and the embedded groove, and the width L1 of the embedded groove in the horizontal direction is connected with the width L2 of the shaft protrusion in the horizontal direction. The difference of width L2 is recorded as L, and the amplitude of the connecting rod driving the tool holder to perform lateral reciprocating linear motion is recorded as A, wherein L is greater than A, so that the rotating rod does not follow the tool holder to perform lateral reciprocating linear motion, and the rotating rod is connected to a rotating lever in the vertical direction on the outside of the left partition or the right partition, and the connection between the rotating rod and the rotating lever is an eccentric shaft connection. Through the eccentric shaft connection between the rotating rod and the rotating lever and the embedded cooperation between the shaft protrusion and the embedded groove, the rotating lever can be turned to fine-tune the angle between the rotating rod and the connecting rod in the vertical direction, and then the distance between the skin splitting knife and the rotating mechanism is adjusted to control the thickness of the splitting allogeneic / heterogeneous skin piece. Such a setting makes the thickness of the splitting allogeneic / heterogeneous skin piece controllable and adjustable, with high precision and easy operation.
