[0024] In a preferred embodiment, the mounting assembly 17 includes a fixed plate 1701, the inner wall of the fixed plate 1701 is rotatably connected to a rotating block 1702, the inner wall of the rotating block 1702 is fixedly sleeved with a fixed collar 1703, the inner wall of the rotating block 1702 is rotatably sleeved with a rotating rod 1704, the inner wall of the fixed collar 1703 is rotatably connected to one end of a connecting rod 1705, the other end of the connecting rod 1705 is rotatably connected to one end of a connecting rod 2 1706 and a fixed plate 1707, and the other end of the connecting rod 2 1706 is rotatably connected to a movable collar 1704. 708, a fixed rail 1709 is fixedly installed on the top of the fixed ring 1703, and a label roll 1710 is movably sleeved on the outer wall of the fixed plate 1707. In the above structure, by rotating the rotating rod 1704, the thread on the outer wall of the rotating rod 1704 rotates, driving the movable ring 1708 to move above the thread, and through the movement of the movable ring 1708, one end of the connecting rod 1706 is driven to move, so that the other end of the connecting rod 1706 expands, driving the fixed plate 1707 to move outward, so that the fixed plate 1707 and the label roll 1710 are tightly attached.
[0025] In a preferred embodiment, the outer wall of the rotating rod 1704 is provided with a thread, and the thread is threadedly connected to the inner wall of the movable ring 1708.

[0029] Working principle: when the device is needed, the label roll 1710 is put on the outside of the fixing plate 1707. At this time, by rotating the rotating rod 1704, the thread on the outer wall of the rotating rod 1704 rotates, driving the movable ring 1708 to move above the thread. Through the movement of the movable ring 1708, one end of the connecting rod 1706 is driven to move, so that the other end of the connecting rod 1706 expands, driving the fixing plate 1707 to move outward, so that the fixing plate 1707 is tightly attached to the label roll 1710, and the three fixing plates 1707 are attached to the inner wall of the label roll 1710, so that the label roll 1710 is fixed by the fixing plate 1707.

At this time, the items to be labeled are placed above the conveyor belt 2, and the conveyor belt 2 drives the items to the label guide 15. When the object reaches the outside of the guide plate 6, the guide plate 6 guides the object to the direction of the label guide 15. When the object reaches the label guide 15, the extrusion force of the object drives the label guide 15 to rotate, so that the label outside the label guide 15 is attached to the surface of the object. When the object is piled up outside the label guide 15, the infrared sensing device 7 detects that there are objects in front and stops moving, and sends a command to the motor 10 to start the motor 10. The motor 10 drives the threaded rod 14 to rotate, and the threaded rod 14 drives the moving ring 11 to move. The moving ring 11 drives the spring 13 to move, so that the spring 13 drives the moving fork 8 to move, and the moving fork 8 moves on the outer wall of the inclined block 9, so that the moving fork 8 moves outward away from the side of the inclined block 9, so that the moving fork 8 leaks out of the strip groove on the outer wall of the guide plate 6, and the moving fork 8 drags the labeled object to the direction of the label guide 15, so that the label guide 15 rotates and pushes the labeled object out.
