To further optimize this solution, as shown in Figure 2, the fixing device includes a label cutting mechanism 30, a ring-shaped mounting frame 31, and a mounting ring 32 located inside the mounting frame 31. The inner side of the mounting ring 32 is provided along the central axial direction. The rotating shaft 33 is fixedly connected to the inner wall of the mounting ring 32. The mounting ring 32 and the rotating shaft 33 rotate intermittently around the central axis of the rotating shaft 33. The mounting ring 32 is provided with several stations at intervals in the circumferential direction, such as As shown in Figure 5, each station is provided with two sliding pins 34, each sliding pin 34 is arranged along the radial direction of the mounting ring 32 and penetrates the end surface of the mounting ring 32, and each station is provided with one Suction cup I 35 for sucking labels, the suction cup I 35 is located between the two sliding pins 34;

The inner side of the mounting ring 32 is provided with a push block mechanism 36 for pushing the two sliding pins 34 outward in the radial direction, and the label cutting mechanism 30 is provided on the outer side of the mounting ring 32, as shown in FIG. 3 , The outer side of the mounting ring 32 is also provided with a winding assembly 37, a flipper 38, a heat sealing assembly I 39, a slitting knife assembly 40, and a heat sealing assembly II 41, the push block mechanism 36, the label cutting mechanism 30, the winding assembly 37, The folding device 38, the heat sealing assembly I 39, the slitting knife assembly 40 and the heat sealing assembly II 41 are arranged in sequence along the rotation direction of the mounting ring 32.

During work, the mounting ring 32 rotates intermittently around the axis of the rotating shaft 33. The rotating shaft 33 is directly connected to the power driving mechanism. The power mechanism of the mounting ring 32 drives the mounting ring 32 to rotate intermittently. When it stops intermittently, the surrounding cotton thread is fixed in length. , Loop forming, label positioning and other mechanism actions.

A number of stations are evenly distributed on the cylindrical surface of the mounting ring 32, preferably 12, and each station is provided with two sliding pins 34 that can slide in the radial direction. The sliding pins 34 are arranged on the inner side of the mounting ring 32. Pushed by the block mechanism 36, it can be pushed out in the radial direction. Each station is provided with a suction cup I 35 at the same time. When the label sent from the push block mechanism 36 is close to the suction cup I 35, the label is adsorbed on the suction cup I 35 and is stationary relative to the mounting ring 32. As the mounting ring 32 rotates clockwise intermittently, the label passes through the remaining stations in sequence. When the label adsorbed on the suction cup I 35 rotates to the winding assembly 37, the cotton thread in the lead pipe 3702 follows the rotation of the tractor 3703 and is wound on the two sliding pins 34 protruding outside the mounting ring 32, and the tractor 3703 rotates The number of turns determines the value of the fixed length of the cotton thread. When the label rotates with the mounting ring 32 below the flipper 38, because the side of the flipper has a gradually protruding slope, the freely extending side of the label is folded, and the center of the label can be set in advance. Folding line, the label is finally folded in half along the pre-cut position of the center dotted line under the action of the folder 38. The side where the label is folded in half can be pre-coated with heat-sealing material. When the half-folded label passes under the heat-sealing assembly I39, the label is folded in half. The two parts are partially heat-sealed together. At this time, the two sliding pins 34 used for winding are retracted into the holes of the mounting ring 32 under the push of the heat-sealing assembly I39. The outer end surface of the sliding pin 34 and the outer side of the mounting ring 32 The end faces are flush, and the previously fixed-length cotton thread ball is fixed in the label due to the heat sealing of the label.
