The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] The following describes an embodiment of the present invention based on its overall structure.

[0025] A chain turning device for an automatic belt threading machine, such as Figures 1-4 As shown, it includes a mounting base 1, a guide block 2 is movably mounted on the end of the mounting base 1, a guide bracket 3 is movably mounted on the top of the mounting base 1, and a connecting block 4 is movably mounted on one side of the guide bracket 3, and the connecting block 4 is movably connected to the mounting base 1, a guide plate 7 is fixed on the top of the mounting base 1, a guide rod 6 is movably connected to one side of the guide bracket 3, and a connecting rod 8 is movably mounted on the other side of the guide bracket 3, a touch rod 62 is fixed on one side of the guide rod 6, and the outer wall of the touch rod 62 is provided with a first spring 63, and the side wall of the guide plate 7 is provided with a card Slot 72, a second spring 81 is fixed to the bottom of the connecting rod 8, and the end of the second spring 81 is fixedly connected to the mounting base 1, and a guide member 5 is movably provided inside the guide bracket 3, which pushes the guide member 5 to move inside the guide bracket 3. When the guide member 5 extends forward, it pushes the touch rod 62 on the guide rod 6 through the inclined surface 704, so that the second pulley 64 at one end of the guide rod 6 moves in an arc trajectory along the slide groove 71 on one side of the guide plate 7, so that the guide bracket 3 is set to a vertical state through the guide rod 6 to facilitate the chain 8 to change its angle during the extension movement.

[0026] See also Figure 1 and Figure 2 A first pulley 61 is movably mounted on the end of the guide rod 6, and a second pulley 64 is movably mounted on the other end of the guide rod 6. The friction between the guide rod 6 and the guide member 5 and the guide plate 7 is reduced by setting the first pulley 61 and the second pulley 64.

[0027] See also Figure 2 A slide groove 71 is provided on one side of the guide plate 7, and the inner wall of the slide groove 71 is set to be arc-shaped. The slide groove 71 can cooperate with the second pulley 64, and the second pulley 64 can move in an arc trajectory along the guide plate 7, so that the guide bracket 3 is set to a horizontal state.

[0028] See also Figure 2 and Figure 3A second slider 41 is installed on one side of the connecting block 4, and a first slider 31 is installed on one side of the guide bracket 3. The outer wall of the connecting rod 8 is provided with a first connecting hole 82 matching the second slider 41, and the outer wall of the connecting rod 8 is provided with a second connecting hole 83 matching the first slider 31. When the guide bracket 3 is set to change the angle, the connecting rod 8 on one side of the guide bracket 3 is driven, and the first connecting hole 81 and the second connecting hole 82 at one end of the connecting rod 8 provide limiting activities for the connecting block 4 and the guide bracket 3, so that the first slider 31 cooperates with the first connecting hole 81, and the second connecting hole 82 cooperates with the second slider 41 to limit them.

[0029] See also Figure 1 and Figure 4 An elastic member is provided inside the guide member 5, and the elastic force of the elastic member is greater than the elastic force of the first spring 63, so that when the guide member 5 is reset, the elastic member contacts the first pulley 61, thereby squeezing the end of the guide rod 6 to move to one side, and according to the lever principle, the other end of the guide rod 6 is disengaged from the slot 72.

[0030] The working principle of the present utility model is as follows: when in use, the chain pushes the guide member 5 to move inside the guide bracket 3, and the guide member 5 pushes the touch rod 62 on the guide rod 6 through the inclined surface 704 when extending forward, so that the second pulley 64 at one end of the guide rod 6 moves in an arc trajectory along the slide groove 71 on one side of the guide plate 7, so that the guide bracket 3 is set to a vertical state through the guide rod 6 to facilitate the chain 8 to change the angle during the extension movement. When the guide bracket 3 is set to change the angle, the connecting rod 8 on one side of the guide bracket 3 is driven along, and the first connecting hole 81 and the second connecting hole 82 at one end of the connecting rod 8 provide limiting activities of the connecting block 4 and the guide bracket 3, so that the first slider 31 and the second slider 41 slide inside them.

[0031] When the external power drives the chain to reset, the chain drives the guide member 5 to reset, and when the movable block 51 on the guide member 5 touches the first pulley 61 at one end of the guide rod 6, the second pulley 64 at the other end of the guide rod 6 is disengaged from the slot 72 and moves in an arc trajectory along the guide plate 7, so that the guide bracket 3 is set to a horizontal state.
