[0018] The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. Unless otherwise specified, the raw materials and equipment used can be purchased from the market or are commonly used in the art. The methods in the embodiments are conventional methods in the art unless otherwise specified. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0019] A label belt traction mechanism comprises a base 1, the surface of the base 1 is fixedly connected to an upper side plate 3 and a lower side plate 5 by a supporting member, an active roller 2 is horizontally arranged between the upper side plate 3 and the base 1, and a driven roller 6 is arranged between the lower side plate 5 and the base 1, the active roller 2 is stably installed, the inner end of the rotating shaft of the driven roller 6 is hinged to the base 1, and the swing plane of the driven roller 6 is vertical. When the driven roller 6 is horizontal, the driven roller 6 is aligned with the active roller 2. When the driven roller 6 swings downward, a gap for the upper and lower belts is formed between the driven roller 6 and the active roller 2; a vertical straight slot hole 51 is provided on the lower side plate 5, and a protruding rod 7 is extended to the outer end of the rotating shaft of the driven roller 6. After the protruding rod 7 protrudes through the straight slot hole 51, it is vertically and rotatably connected to a lock buckle 8, and the side of the lock buckle 8 has a bayonet 81. A clamping rod 4 is arranged on the outer surface of the upper side plate 3. When the driven roller 6 is horizontal, the rotating lock buckle 8 can be clamped on the clamping rod 4 through the bayonet 81.

[0020] In order to further improve the firmness of the clamping connection, the clamping rod 4 is cylindrical, and a fastening screw 9 is provided at the end of the lock buckle 8 away from the protruding rod 7. The fastening screw 9 is located on the outside of the bayonet 81. When the bayonet 81 is clamped on the clamping rod 4, tightening the fastening screw 9 can press the clamping rod 4 into the bayonet 81 to enhance the firmness of the clamping connection.

[0021] A label belt traction mechanism, when used:

[0022] The driven roller 6 swings down, causing the outer end of the driven roller 6 to lower, forming a gap between the driven roller 6 and the active roller 2, placing the label tape between the two rollers, and then lifting the driven roller 6, so that the driven roller 6 swings up to a horizontal state and cooperates with the active roller 2 to clamp the label tape, and turning the lock buckle 8 counterclockwise to clamp the bayonet 81 on the clamping rod 4 to complete the fixation of the posture of the driven roller 6. At this time, starting the active roller 2 can pull the label tape; when the label tape needs to be removed, turn the lock buckle 8 clockwise to separate the bayonet 81 and the clamping rod 4, and swing the driven roller 6 down to take out the label tape sideways.
