Referring to fig. 1, the movement frame 1 includes a left side plate 11 and a right side plate 12 which are vertically arranged in parallel, a fixing screw 13 is arranged between the left side plate 11 and the right side plate 12 in a penetrating manner, four fixing nuts 131 are sleeved on the fixing screw 13, the four fixing nuts 131 are distributed on two sides of the left side plate 11 and the right side plate 12 in a pairwise manner, and the fixing nuts 131 are connected with the fixing screw 13 in a threaded manner. Through the position adjustment of the fixing nut 131 on the fixing screw 13, the gap between the left side plate 11 and the right side plate 12 can be adjusted, and the swing arm assembly 2 with different widths can be further adapted.

Referring to fig. 1 and 3, the swing arm assembly 2 includes a rotation column 21 rotatably installed between the left side plate 11 and the right side plate 12, a left swing arm 22, a guide plate swing rod 23 and a right swing arm 24 which are installed on the rotation column 21 in sequence in a rotating manner, a connecting belt plate 25 is fixedly installed between the left swing arm 22 and the right swing arm 24, a guide plate 26 is fixedly installed at the upper end of the guide plate swing rod 23, and a guide gap 261 for penetrating a packing belt is arranged on the guide plate 26. Referring to fig. 1, a mounting plate 111 is mounted on the left side plate 11, and the tension spring assembly 3 includes a first tension spring 31 and a second tension spring 32. The upper end of the first tension spring 31 is connected with the mounting plate 111, and the other end is connected with the left swing arm 22. One end of the second tension spring 32 is connected with the mounting plate 111, and the other end is connected with the guide plate swing rod 23. The lower end of the left swing arm 22 and the lower end of the guide plate swing rod 23 are both detachably provided with a swing arm tension spring pulling plate 221, the swing arm tension spring pulling plate 221 is rotatably provided with a connecting stud 222, and the connecting stud 222 is in threaded connection with two adjusting nuts 223.

Referring to fig. 3, the movement frame 1 is further provided with an angle adjusting mechanism 4, the angle adjusting mechanism 4 includes an adjusting rod 41 penetrating between the left side plate 11 and the right side plate 12, a speed reducing motor 42 fixedly installed on the right side plate 12, and an adjusting cam 43 sleeved on the adjusting rod 41, as shown in fig. 4, an output end of the speed reducing motor 42 is fixedly connected with the adjusting rod 41, and the adjusting cam 43 is provided with a positioning opening 431. The guide plate swing link 23 is rotatably provided with a positioning buffer wheel 231 fitted into the positioning opening 431. The positioning buffer wheel is further provided with a convex part 432. When the speed reducing motor 42 is started, the adjusting rod 41 drives the adjusting cam 43 to rotate, and when the baler operates, the guide plate swing rod 23 is positioned at different rotation angles under the action of the positioning buffer wheel 231, so that the baler is suitable for baling belts with different tensities. A swing arm ejecting support 241 is fixedly mounted on the right swing arm 24, and a swing arm buffer block 242 for buffering the guide plate swing rod 23 is sleeved on the swing arm ejecting support 241, so that the collision vibration of the guide plate swing rod 23 and the swing arm limiting block 28 can be favorably relieved.

First extension spring 31 provides the binding power for left swing arm 22 and right swing arm 24, and right swing arm 24 is connected into an open type one-tenth slider swing arm structure by connecting plate 25 and left swing arm 22, makes this structure work the back rebound. And a second spring 32 for providing a binding force to the guide swing link 23 so that the positioning buffer wheel 231 mounted on the guide swing link 23 is brought into close contact with the adjustment cam.

The working principle of the embodiment is as follows: during working, a packing belt firstly penetrates through the guide gap 261 to reach the belt path, and then winds one circle along the belt path (namely one circle around a packed object) to reach the guide gap 261 again to carry out actions such as belt sticking, belt cutting and belt releasing. When the belt is taken off, the guide plate swing rod 23 moves outwards around the rotating column 21 under the action of the transmission cam 43 and touches the swing rod buffer block 242 to drive the whole swing arm assembly to move outwards, so that the belt-off action is completed. Then, since the rotation angle of the adjustment cam 43 does not act on the positioning buffer wheel 231 on the guide plate swing link 23 at this time, the whole device is rapidly rebounded due to the binding force of the first spring 31 and the second spring 32. And because the swing arm stopper 28 is equipped with the setting of polyurethane shockproof cushion 281 and location buffer wheel 231, slow down baffle pendulum rod 23 and swing arm stopper 28 to and swing arm stopper 28 respectively with the left side board 11 and the right side board 12 between the collision vibrations, be favorable to more effectual packing operation, also avoid long-term collision to cause mechanical properties and stability variation.
