[0017] The utility model will be further described below in conjunction with the drawings and preferred embodiments.
[0018] Embodiment 1
[0019] Refer to Figure 1 and Figure 2As shown, the present embodiment involves a large-roll fabric loosening machine with adjustable swing amplitude, comprising a frame 1, a feeding roller 2 near the top of the frame 1 is rotatably connected, a feeding platform 3 near the bottom is fixedly connected to the frame 1, a cloth loosening mechanism arranged on the frame 1 is arranged between the feeding platform 3 and the feeding roller 2, the cloth loosening mechanism comprises a cloth loosening bucket 4 rotatably connected to the frame 1, the top of the cloth loosening bucket 4 has a feeding port 401 for inputting fabric, and the bottom has a discharge port 402 for outputting fabric, a driving shaft 5 is rotatably connected to the frame 1, one end of the driving shaft 5 is transmission-connected to a power assembly (not shown) for controlling the rotation, a first connecting rod 6 and a second connecting rod 7 hinged to each other are arranged between the driving shaft 5 and the cloth loosening bucket 4, the end of the second connecting rod 7 not connected to the first connecting rod is hinged to the cloth loosening bucket 4, the end of the first connecting rod 6 not connected to the second connecting rod is fixedly connected to the driving shaft 5, and the length of the second connecting rod 7 is adjustable.
[0020] Furthermore, the second connecting rod 7 includes an adjusting screw 71 with an internal thread in the center hole, the internal thread of the adjusting screw 71 is connected with two adjusting screws 72 extending out of the pipe orifices respectively, and the ends of the adjusting screws 72 extending out of the pipe orifices are provided with a connecting head 73 for hinge connection, and the adjusting screw 71 is in a non-rotating columnar shape;
[0021] When the adjusting screw tube 71 rotates clockwise relative to the adjusting screw rod 72, the two adjusting screw tubes 71 gradually extend into the tube; when the adjusting screw tube 71 rotates counterclockwise relative to the adjusting screw rod 72, the two adjusting screw tubes 71 gradually extend out of the tube.
[0022] Furthermore, the connector 73 is provided with a rotating portion 74 which is also in the shape of a non-rotating column.
[0023] In this embodiment, the adjusting screw 71 is rotated clockwise relative to the adjusting screw 72 so that the two adjusting screws 71 extend into the tube, thereby shortening the length of the second connecting rod 7, thereby reducing the swing amplitude of the cloth loosening bucket 4; the adjusting screw 71 is rotated counterclockwise relative to the adjusting screw 72 so that the two adjusting screws 71 extend out of the tube, thereby extending the length of the second connecting rod 7, thereby increasing the swing amplitude of the cloth loosening bucket 4.
[0024] Among them, by setting the adjusting screw 71 as a non-rotating columnar structure, a rotating part 74 which is also a non-rotating columnar structure is also set on the connecting head 73 for use as a lever, so that the two (adjusting screw 71 and adjusting screw 72) can be easily rotated relative to each other.

[0028] In this embodiment, by respectively providing C-shaped rings 43 at the upper and lower ends of the hopper end plate 42, on the one hand, it is used for threading the round bar 44, so that the hopper end plate 42 connected to the hopper side plates 41 does not need to be connected to the hopper side plates 41 by welding. On the other hand, the sharp edges originally exposed at the upper and lower edges are hidden, preventing the incoming fabric from being scratched and making the fabric conveying smoother.

The overall function is perfect and the practicability is strong.
