There is a long hole 81 whose axial direction is the same as the long axial direction of the second slider 80; one end of the frame body 90 is fixedly connected to the middle section of the belt guide frame 30, and the other end has a vertical shaft tube 91 which is pivotally connected to an appropriate position inside the body 11 , the upper end of the middle part of the frame body 90 is inserted into the bolt body 92, and the upper end of the bolt body 92 is inserted from the long hole 81 on the bottom surface of the second slide block 80. , the other end of the spring 94 is hooked on the upright rod 95 protruding from the bottom surface of the frame plate 12, so that the telescopic axis of the spring 94 is roughly parallel to the long axis of the first slider 70.

As shown in Fig. 7, Fig. 8 and Fig. 9, when the bales 1 are large, the utility model is not easy to cover the tightening belt feeding device, and the user only needs to pull the free end of the baling belt 7 to the main and auxiliary Between the feeding pulleys 20 and 40, the motor 21 can drive the main feeding pulley 20 and the secondary feeding pulley 40 to automatically roll the packing belt 7 into the belt guide frame 30 to tighten the bundle 1 , to achieve the function of unhindered tightening belt and automatic belt entry.

As shown in Fig. 5, Fig. 6 and Fig. 10 to Fig. 15, when the utility model tightens the package 1, the transmission member 50 receives electric control to make the motor 51 rotate, and the camshaft 53 rotates in conjunction with it. At this time During the rotation of the cam 531, the displacement of the flat tangent surface 532 on the outer periphery of the cam 531 impels the pulley 63 on the connecting rod 60 to reach the end of the tangent surface 532 first, and the pulley 63 is pushed to make the connecting rod 60 slightly to one side with the bottom as the fulcrum. swing (as shown in Figure 12 and Figure 13), and then use the top end of the connecting rod 60 to engage the positioning bolt 75 of the first slider 70, so that the first slider 70 slides towards the same side, at this time, the main belt The guide bolts on the bottom surface of the seat plate 22 of the wheel 20 pass through the long guide hole 732, and the seat plate 22 is moved back by the displacement of the guide bolt 23, that is, the first long guide hole 121 of the guide bolt 23 on the frame plate 12 Displacement (as shown in Figure 6), so when the main feed pulley 20 is separated from the auxiliary feed pulley 40 by the linkage of the seat plate 22, the seat plate 22 retreats and utilizes the bolt 24 to stretch the spring 25 at the same time, and the bolt 24 is in the second long guide Displacement in the guide hole 122 (as shown in Figure 6), when the rotation range of the cam 531 is relatively large, the pulley 63 crosses the end of the flat tangent surface 532 and is introduced into the outer circumferential surface of the cam 531. Prompt the top of the connecting rod 60 to drive the first slider 70 to make a long distance displacement, so that the first slider 70 is linked with the displacement of the long hole 81 of the second slider 80 on the bottom surface and leans against the bolt body 92 and is moved. After the body 92 is actuated, it also drives the frame body 90 to swing towards the same side with the vertical shaft tube 91 as the fulcrum, so the frame body 90 together with the belt guide frame 30 and the auxiliary belt pulley 40 are tilted towards the same side, so that the packing belt 7 Break away from the belt guide frame 30 and tighten the package 1. At this time, the reset bolt 76 of the first slide block 70 stretches the spring 78, and the vertical rod 93 of the frame body 90 also stretches the spring 94. When the cam 531 turns back to the flat After the center of the cut surface 531 touches the pulley 63 of the connecting rod 60, the pulley 63 loses the thrust and the connecting rod 60 recovers, and the first slider 70, the seat plate 22 and the frame body 90 are supported by the spring 78. , 25, 94 are pulled back by the recovery elasticity, and are in a normal positioning state (as shown in Figure 10 and Figure 11), so that when the bundle 1 is tightened, the strap 7 can be pulled out smoothly, making the operation easy to use .
