However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: Figure 1-Figure 5 As shown, the utility model provides a pure cotton spunlace non-woven bag stretching mechanism, comprising: a U-shaped frame 1; a stretching assembly 2, the stretching assembly 2 is fixedly connected to the inner surface of the U-shaped frame 1, the stretching assembly 2 comprises a mounting plate 201, a top plate 202 and a transmission belt 208, the top of the top plate 202 is symmetrically fixedly connected to a support plate 205, and stretching rollers 211 are symmetrically arranged between the opposite surfaces of the two support plates 205, and the outer surfaces of the two stretching rollers 211 are both provided with a bidirectional threaded sleeve 209, and the outer surfaces of the two stretching rollers 211 are fixedly connected to a second pulley 210 near one end face, and the inner side of one of the support plates 205 is fixedly connected to a motor 206, and the output end of the motor 206 rotates and passes through the outer surface of one of the support plates 205, and the output end of the motor 206 is fixedly connected to a first pulley 207, and the first pulley 207 is connected to the two second pulleys 210. The pulley 210 is connected through the transmission belt 208, and the outer surfaces of both sides of the mounting plate 201 are fixedly connected to the inner surface of the U-shaped frame 1 respectively. A plurality of springs 204 are fixedly connected between the mounting plate 201 and the top plate 202. The bottom of the top plate 202 is fixedly connected to the guide rod 203 near the four corners. The outer surfaces of the plurality of guide rods 203 are slidingly connected to the inner surface of the mounting plate 201. The outer surfaces of the plurality of stretching rollers 211 are rotatably connected to the inner surfaces of the two support plates 205 near the two end faces. The spring 204 is located on the outside of the guide rod 203. A first mounting rod 212 is fixedly connected between the opposite surfaces of the two support plates 205. The outer surface of the first mounting rod 212 is rotatably connected to the first hollow cylinder 213. The inner surface of the U-shaped frame 1 is symmetrically fixedly connected to a plurality of second mounting rods 4, and the plurality of second mounting rods 4 are staggered.

[0025] The effect achieved by the entire embodiment 1 is that when the non-woven bag raw material is stretched, the non-woven fabric fabric is sequentially adhered to the surfaces of the multiple staggered second hollow cylinders 3 under the traction of external power. When the multiple second hollow cylinders 3 are adhered and moved, the multiple second hollow cylinders 3 will synchronously rotate on the outer surfaces of the multiple second mounting rods 4, which plays a role in stretching and shaping its length. At the same time, when it is adhered to the surfaces of the two bidirectional threaded sleeves 209 and the first hollow cylinder 213, the first hollow cylinder 213 will rotate on the surface of the first mounting rod 212, so that the non-woven fabric plays a limiting role when moving below it, so that it can be closely attached to the outer surfaces of the two bidirectional threaded sleeves 209, and the motor 206 is started.

[0027] The effect achieved by the entire embodiment 2 is that, when in use, by symmetrically fixing the connecting ring blocks 5 on the outer surface of the second mounting rod 4, when the non-woven fabric is stretched in length, the second hollow tube 3 will be limited to rotate within the two ring blocks 5, and at the same time the non-woven fabric will be limited to prevent its position from shifting, and it is highly practical.

When the multiple second hollow cylinders 3 are adhered and moved, the multiple second hollow cylinders 3 will synchronously rotate on the outer surfaces of multiple second mounting rods 4, which plays a role in stretching and shaping its length. At the same time, when it is adhered to the surfaces of the two bidirectional threaded sleeves 209 and the first hollow cylinder 213, the first hollow cylinder 213 will rotate on the surface of the first mounting rod 212, so that the non-woven fabric plays a limiting role when moving below it, so that it can be closely attached to the outer surfaces of the two bidirectional threaded sleeves 209, start the motor 206, and the output end of the motor 206 rotates through one of the support plates 205, and drives the first pulley 207, and transmits the two second pulleys 210 through the transmission belt 208, so that the two stretching rollers 211 will rotate synchronously between the two support plates 205. The surfaces of the two stretching rollers 211 are set The bidirectional threaded sleeve 209 can pull the non-woven fabric in contact with it to both sides and gradually stretch it under rotation, so that the non-woven fabric can be stretched laterally, which plays a role of transverse stretching and can prevent deformation and tearing damage to the non-woven fabric. By fixing multiple springs 204 between the mounting plate 201 and the top plate 202, and the mounting plate 201 is fixed to the inner side of the U-shaped frame 1, when the non-woven fabric moves in contact with the two bidirectional threaded sleeves 209, the deformation, contraction and rebound force of the springs 204 are utilized, and the top plate 202 will move up and down in the mounting plate 201 through multiple guide rods 203, automatically adapting to the tension of the non-woven fabric, avoiding the non-woven fabric from being too tight or too loose during stretching, and by symmetrically fixing the connecting ring blocks 5 on the outer surface of the second mounting rod 4, when the non-woven fabric is stretched in length, the second hollow cylinder 3 will be limited to rotate in the two ring blocks 5, and at the same time, the non-woven fabric will be limited to prevent its position from shifting, which is highly practical.
