[0031] The inner wall of the cross frame 2 is symmetrically provided with grooves 301, and push rods 302 are rotatably connected inside the two grooves 301.

In order to facilitate the folding of the non-woven fabric, the outer side of the movable block 305 is slidably connected to the inner wall of the groove 301, and the traction motor 308 is powered by an external power supply. The bottom end of the horizontal frame 2 is connected to a supporting plate by bolts at a position corresponding to one side of the bracket 309, and the clamping roller 312 is unidirectionally rotating.

[0033] A clamping and traction mechanism 4 is provided at the top and bottom of the fixed frame 1 corresponding to the horizontal frame 2. The clamping and traction mechanism 4 includes a horizontal frame 401, a rotating drum 402, a top rod 403, a slider 404, a roller 405, a rotating motor 406, a horizontal plate 407, a fixed plate 408, a lifting rod 409 and a height limiting plate 410.

[0034] The interior of the fixed frame 1 is connected to a horizontal frame 401 at the top and bottom positions corresponding to the horizontal frame 2 by bolts. The inner wall of the horizontal frame 401 is symmetrically connected to a rotating drum 402. The interior of the two rotating drums 402 is connected to a push rod 403 by threads. The adjacent ends of the two opposing push rods 403 are clamped with a slider 404. A roller 405 is rotatably connected between the sliders 404 inside the two horizontal frames 401 located in the same horizontal plane. A rotating motor 406 is bolted to one end of each slider 404 at a position corresponding to the side of the rotating shaft of the roller 405.

[0035] A horizontal plate 407 is clamped at the bottom position of the interior of the fixed frame 1, and a fixed plate 408 is clamped between the two horizontal plates 407. The interior of the fixed plate 408 is symmetrically connected to a lifting rod 409 through a thread. The top of the two lifting rods 409 are rotatably connected to a height limit plate 410. In order to facilitate the traction and clamping of the non-woven fabric, there are four horizontal frames 401. A knob is fixedly sleeved on the outside of the rotating drum 402. The top and bottom ends of the slider 404 are slidably connected to the inner wall of the horizontal frame 401. The rotating motor 406 is powered by an external power supply. A turntable is clamped at the bottom of the two lifting rods 409.

[0036] A rectangular groove 5 is provided at one side of the top of the fixed frame 1, and an adjusting rod 6 is rotatably connected inside the rectangular groove 5. A movable baffle 7 is threadedly sleeved on the outside of the adjusting rod 6. A fixed baffle 8 is bolted at the other side of the top of the fixed frame 1, and one end of the fixed baffle 8 is rotatably connected to a support rod 9. Rotating rods 10 are threadedly connected at both sides of the corresponding support rods 9 inside the movable baffle 7 and the fixed baffle 8. One end of the two rotating rods 10 on the same side is rotatably connected to a limiting ring 11. In order to facilitate the installation and limiting of the non-woven fabric roll, the top positions at both ends of the movable baffle 7 are slidably connected to the inner wall of the rectangular groove 5, and a circular hole is provided inside the movable baffle 7 at the position corresponding to the outer side of the support rod 9, and the inner wall of the limiting ring 11 fits in place with the outer side of the support rod 9.

[0037] The working principle and usage process of the utility model are as follows: first, the adjusting rod 6 is rotated forward to push the movable baffle 7 to move along the rectangular groove 5, so that the movable baffle 7 moves out of the rectangular groove 5, which is convenient for rotating the movable baffle 7 to release the obstruction of the support rod 9, so that the non-woven fabric roll is placed on the support rod 9, and then the movable baffle 7 is pressed and the adjusting rod 6 is reversed to bring the movable baffle 7 back into the rectangular groove 5, thereby limiting the non-woven fabric roll, improving the convenience of installation, and rotating the rotating rod 10 to push the limiting ring 11 to move, changing the distance between the two limiting rings 11, further limiting the non-woven fabric roll, preventing deviation, and ensuring the effect of subsequent traction and transportation;

[0038] Next, the rotating drum 402 pushes the top rod 403 and the slider 404 to slide inside the horizontal frame 401, thereby driving the roller 405 to move. According to the thickness of the non-woven fabric, the distance between the two rollers 405 on the same horizontal plane is adjusted to facilitate clamping and fixing the non-woven fabric. Then, the rotating motor 406 is started to drive the roller 405 to rotate and pull the non-woven fabric. At the same time, according to the processing requirements of the non-woven bag, the lifting rod 409 is rotated to push the height limiting plate 410 up and down, thereby changing the height of the height limiting plate 410. After the bottom end of the non-woven fabric contacts the height limiting plate 410, the rotating motor 406 is stopped to pull out the required length of the non-woven fabric, thereby improving adaptability.

[0039] Finally, after the non-woven fabric is pulled, the traction motor 308 is started to drive the push rod 302 to rotate, and the power is transmitted through the cooperation of the sprocket 303 and the chain 304, so that the two push rods 302 rotate together to push the movable block 305 and the folding rod 307 to move inside the horizontal frame 2, folding and pushing the non-woven fabric. At the same time, due to the telescopic characteristics of the tensioning spring 306, it is convenient for the folding rod 307 to carry the non-woven fabric through the clamping roller 312, so that the non-woven fabric is folded and placed on the support plate, which is convenient for subsequent cutting and transportation. When the traction motor 308 drives the push rod 302 to reverse, when the movable block 305 and the folding rod 307 are pulled to reset, the concave plate 311 and the clamping roller 312 are pushed to move by the tensioning spring 306 to clamp the non-woven fabric, preventing the non-woven fabric from moving with the folding rod 307, thereby ensuring the folding effect.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
