At the same time, terms such as "left", "right", "up", "down", and "one" quoted in this specification are only for the convenience of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments in their relative relationships, without substantially changing the technical content, should also be considered as the scope of implementation of the present invention.

[0021] Please combine Figure 1 and Figure 2 The baler includes a tensioning device and a welding device. The tensioning device is used to tighten the strapping tape, and the welding device is used to cut and weld the strapping tape. The welding device includes a welding structure 1 and a clutch connection structure 2. The welding structure 1 and the clutch connection structure 2 are connected. When the clutch connection structure 2 rotates in a first rotation direction, the welding structure 1 is pressed down. At the same time, the motor of the clutch connection structure 2 drives the welding structure 1 to rub the strapping tape to perform the welding operation. When the clutch connection structure 2 rotates in the second rotation direction, which is opposite to the first rotation direction, the welding structure 1 is lifted, interrupting the welding operation.

[0022] The welding structure 1 includes a friction component 11, a movable upper tooth 12 and a movable lower tooth 13. The movable upper tooth 12 is installed on the friction component 11; the movable lower tooth 13 is located below the movable upper tooth 12, and the strapping tape is located between the movable upper tooth 12 and the movable lower tooth 13. The movable lower tooth 13 fixes the lower strapping tape, and the movable upper tooth 12 drives the upper strapping tape to move back and forth, so that the two layers of strapping tape rub against each other to generate heat for welding.

[0023] The clutch connection structure 2 includes a rotating shaft 21, a mounting seat 22, a connecting rod assembly 23, a sector gear 24, a motor 25 and an output assembly 26. The rotating shaft 21 is movably mounted on the mounting seat 22; one end of the connecting rod assembly 23 is movably connected to the friction component 11, and the other end is movably connected to the sector gear 24. The connecting rod assembly 23 drives the friction component 11 to be pressed down or lifted in the first rotation direction and the second rotation direction through the sector gear 24; the sector gear 24 is movably connected to the rotating shaft 21; the output end of the motor 25 is connected to the output assembly 26; and the output assembly 26 is movably meshed with the sector gear 24.

[0024] Please combine Figure 3 、 Figure 4 and Figure 5 The sector gear 24 includes a body 241, a movable tooth 242, a mounting groove 243, an elastic member 244 and a cover plate 245. The body 241 is provided with teeth in the first rotation direction and the second rotation direction, respectively, which are movably engaged with the output component 26; the movable tooth 242 is the first tooth at the front end of the body 241 in the second rotation direction; the mounting groove 243 is opened at the front end of the body 241 in the second rotation direction, and the movable tooth 242 is installed in the mounting groove 243; the elastic member 244 is installed in the mounting groove 243, the elastic member 244 presses against the movable tooth 242, and the movable tooth 242 is extended and retracted by the elastic member 244; the cover plate 245 is fixedly installed on the body 241, covering the mounting groove 243, to prevent the movable tooth 242 and the elastic member 244 in the mounting groove 243 from falling out.

[0025] The output assembly 26 includes an output shaft 261, a first gear 262, a second gear 263 and an output component 264. The output shaft 261 is connected to the motor 25. The first gear 262 and the second gear 263 are sleeved on the output shaft 261. The first gear 262 and the second gear 263 are respectively engaged with the double-layer teeth of the body 241; the output component 264 is sleeved on the output shaft 261 and connected to the second gear 263.

[0026] In the first rotation direction, when the motor 25 drives the output shaft 261 to rotate, the output shaft 261 drives the second gear 263 to rotate. At this time, the second gear 263 is engaged with the sector gear 24, and the movable teeth 242 are engaged with the teeth of the second gear 263. The second gear 263 drives the sector gear 24 to rotate until the second gear 263 is disengaged from the sector gear 24. In the second rotation direction, when the motor 25 drives the output shaft 261 to rotate, the output shaft 261 drives the first gear 262 to rotate, and the first gear 262 is always engaged with the sector gear 24. The first gear 262 drives the sector gear 24 to rotate, and the sector gear 24 and the second gear 263 are disengaged and engaged. During this process, there may be an abnormal engagement when the sector gear 24 and the second gear 263 just come into contact. The movable tooth 242 is forced to compress the elastic part 244, and the movable tooth 242 retreats to avoid the second gear 263. As the second gear 263 continues to rotate in the second rotation direction, the movable tooth 242 is engaged with the second gear 263, and the sector gear 24 and the second gear 263 enter a meshing state.

[0027] In summary, the present invention can effectively avoid the baler from getting stuck when the working state is changed by replacing the first tooth with an elastically retractable movable tooth, thereby facilitating the automatic control of the baler and reducing external operation intervention.

[0028] Therefore, the present invention effectively overcomes the shortcomings of the prior art and possesses high industrial value. The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
