[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 by rotating 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; the output assembly 26 is movably meshed with the sector gear 24.

[0024] Please combine Figure 3 and Figure 4 The output assembly 26 includes an output shaft 261, a first output gear 262, a second output gear 263, a driving block 264, an output component 265 and a torsion spring 266. The output shaft 261 is connected to the output end of the motor 25; the first output gear 262, the second output gear 263, the driving block 264 and the output component 265 are sequentially mounted on the output shaft 261; the first output gear 262 is always meshed with the sector gear 24, and the second output gear 263 is always meshed with the sector gear 24. The wheel 24 is movably engaged and connected. In the first rotation direction, the sector gear 24 and the second output gear 263 are disengaged from the meshing connection. In the second rotation direction, the sector gear 24 and the second output gear 263 are re-engaged; the driving block 264 rotates synchronously with the output shaft 261; the torsion spring 266 is located between the second output gear 263 and the driving block 264, and one end of the torsion spring 266 is inserted into the second output gear 263, and the other end is inserted into the driving block 264 for releasing torque.

[0025] The output shaft 261 includes a round shaft 2611 and a flat shaft 2612. The round shaft 2611 is the end of the output shaft 261 connected to the motor 25, and the flat shaft 2612 is the end of the output shaft 261 away from the motor 25. The first output gear 262 is mounted on the round shaft 2611, and the second output gear 263 is mounted at the intersection of the round shaft 2611 and the flat shaft 2612.

[0026] The second output gear 263 includes a first shaft hole 2631, a gear body 2632 and a torsion spring seat 2633. The first shaft hole 2631 is opened at the center of the gear body 2632, and the first shaft hole 2631 is a circular hole; the gear body 2632 is fixedly connected to the torsion spring seat 2633, and the torsion spring seat 2633 is an annular structure with a notch. The gear body 2632 is sleeved on the round shaft 2611, and the torsion spring seat 2633 is located on the flat shaft 2612. The torsion spring 266 is sleeved on the flat shaft 2612 and is located in the torsion spring seat 2633. The driving block 264 is sleeved on the flat shaft 2612 and is located in the torsion spring seat 2633.

[0027] The driving block 264 includes a second axial hole 2641, a driving block body 2642 and a protrusion 2643. The second axial hole 2641 is opened in the middle position of the driving block body 2642, consistent with the shape of the flat shaft 2612, and is used to rotate synchronously with the output shaft 261; the protrusion 2643 is arranged on the side of the driving block body 2642, and the protrusion 2643 is located at the notch of the torsion spring seat 2633.

[0028] Specifically, in the initial state, the protrusion 2643 does not contact the torsion spring seat 2633, so that the second output gear 263 has a deflection angle space in the first rotation direction and the second rotation direction relative to the driving block 264; during the rotation process in the first rotation direction and the second rotation direction, the protrusion 2643 touches the torsion spring seat 2633.

[0029] In the first rotation direction, the motor 25 drives the output shaft 261 to rotate, and the output shaft 261 drives the driving block 264 to rotate synchronously. The protrusion 2643 located at the front of the rotation direction contacts the torsion spring seat 2633 and drives the second output gear 263 to rotate. At this time, the second output gear 263 is engaged with the sector gear 24, and the second output gear 263 drives the sector gear 24 to rotate until the second output gear 263 is disengaged from the sector gear 24. After disengagement, the elastic force of the torsion spring 266 is released, so that the protrusion 2643 is not in contact with the torsion spring seat 2633. During the entire process of rotation in the first rotation direction, the first output gear 262 and the sector gear 24 are always engaged, and the sector gear 24 drives the first output gear 262 to rotate. In the second rotation direction, the motor 25 drives the output shaft 261 to rotate, and the output shaft 261 drives the first output gear 262 to rotate synchronously. The first output gear 262 drives the sector gear 24 to rotate, and the sector gear 24 and the second output gear 263 are disengaged and engaged. During this process, there may be abnormal engagement when the sector gear 24 and the second output gear 263 just come into contact. At this time, the torsion spring 266 drives the second output gear 263 to rotate in the first rotation direction or the second rotation direction according to the force situation, completing the engagement and reducing the risk of the sector gear 24 and the second output gear 263 being stuck.

[0030] In summary, the utility model provides a certain angle of deflection in both the first rotation direction and the second rotation direction by designing the drive block and the torsion spring seat, so that the sector gear and the second output gear can more smoothly change from the disengaged state to the engaged state, which can effectively avoid the baler from getting stuck when the working state is switched, facilitate the automatic control of the baler, and reduce external operation intervention.
