In actual operation, the last station transfers the face tissues and the shells (the inner part is the round-corner paperboard and the outer part is the right-angle face tissues) which are coated with the glue and the edges of the round-corner paperboards to the second belt 17, the second driving mechanism 18 drives the second belt 17 to rotate, and the rotating second belt 17 transfers the shells to the first belt 12. The second belt 17 limits the leather shells conveyed by the second belt 17 in the leather shell conveying process by the second limiting plate 19, so that the leather shells can move in the correct direction. The second adjusting mechanism 110 can adjust the position of the second limiting plate 19 according to shells of different sizes, so as to meet the processing requirements of shells of different sizes.

Since the rounding mechanism 2 can only round one skin at a time, after the second belt 17 conveys the skin to the first belt 12, the skins are gradually stacked on the first belt 12, when the number of the skins on the first belt 12 is greater than the set number, the second belt 17 stops conveying the skins to the first belt 12, and when the number of the skins on the first belt 12 is less than the set number, the second belt 17 conveys the skins to the first belt 12 again.

When the fillet mechanism 2 finishes processing a piece of leather shell, the fillet mechanism 2 signals the control cabinet, and the control cabinet controls the first driving mechanism 13 to drive the first belt 12 to rotate, and the rotating first belt 12 conveys the piece of leather shell contacted with the first belt 12 to the conveying device 22. Specifically, the rotating first belt 12 drives the piece of skin contacting the first belt 12 through the slit 114 and conveys the skin to the conveyor 22, and the striker plate assembly 112 blocks the remaining skin stacked on the first belt 12, ensuring that the first belt 12 conveys only one skin at a time to the conveyor 22. During the process of conveying the shells by the first belt 12, the first limiting plate 14 limits the shells conveyed by the first belt 12, so that the shells can move along the correct direction, and the shells can pass through the gaps 114. The first adjusting mechanism 15 can adjust the position of the first limiting plate 14 according to shells of different sizes, so as to meet different working conditions.

The second workbench 16 can adjust the relative position of the second workbench 16 and the first workbench 11 according to actual production conditions, so as to meet production requirements. Specifically, the third driving mechanism 111 drives the second table 16 to slide along the first table 11 to adjust the relative position of the second table 16 and the first table 11.

In operation, the leather shell feeder 1 can fully automatically convey leather shells to the round corner mechanism 2, the automation degree is high, the labor intensity and the labor cost are greatly reduced, and the production efficiency is improved.

The first belt 12 conveys the leather sheath (the inside is the fillet cardboard, the outside is the right angle facial tissue) after the facial tissue and the fillet cardboard rubberizing cover are bound to conveyor 22, conveyor 22 carries the leather sheath to the fillet processing station again, then four fillet processing apparatus 24 remove to the center of leather sheath and carry out the fillet processing to the right angle facial tissue of four angles of leather sheath simultaneously.
