At both ends of the tension adjusting roller 3, there are first sliders 4. On one side of both first sliders 4, there is an adjusting mechanism. At the top of the mounting plate 1, there is a connecting frame 5. Inside the connecting frame 5, there are two first electric telescopic rods 6. At one end of the two first electric telescopic rods 6, there is a first cleaning brush 7. On one side of the first cleaning brush 7, there is a second cleaning brush 8. On one side of the connecting frame 5, there is a flattening mechanism. On the surface of the mounting plate 1, there is a moving mechanism. The moving mechanism includes two chutes opened on the surface of the mounting plate 1. Inside the two chutes, there are a forward and reverse screw rod 9 and a first slide bar 10 respectively. On both the forward and reverse screw rod 9 and the first slide bar 10, there is a second slider 11. At the top of both second sliders 11, there is a second support plate 12. On one side of the mounting plate 1, there is a first motor 13. The output end of the first motor 13 is connected to the forward and reverse screw rod 9. Between the two second support plates 12, there are guide rollers 14. On the surfaces of the second support plate 12 and the first slider 4, there are two second electric telescopic rods 15. At one end of the two second electric telescopic rods 15, there is a baffle 16. The cross-section of the baffle 16 is arc-shaped. When the spunbond non-woven fabric is conveyed on the mounting plate 1, first, the first electric telescopic rod 6 inside the connecting frame 5 drives the first cleaning brush 7 to clean the upper surface of the spunbond non-woven fabric according to the thickness of the spunbond non-woven fabric. The second cleaning brush 8 on the surface of the mounting plate 1 cleans the lower surface of the spunbond non-woven fabric during its conveyance, so that the debris on the surface of the spunbond non-woven fabric can be conveniently processed. The spunbond non-woven fabric is subjected to tension detection between the guide roller 14 and the tension adjusting roller 3. The first motor 13 drives the forward and reverse screw rod 9 to rotate. The forward and reverse screw rod 9 drives the second slider 11 to rotate. The second slider 11 drives the second support plate 12 to move left and right. It can also drive the second support plate 12 on the other side to drive the slider to move on the slide bar, thereby driving the mechanism between the second support plates 12 to move left and right. Then, the second electric telescopic rod 15 drives the baffle 16 to block the spunbond non-woven fabric according to its width on the guide roller 14, preventing the spunbond non-woven fabric from shifting during the conveyance and tension test. This enables the device to adjust the distance between the tension adjusting roller 3 and the guide roller 14 according to the width and length of the spunbond non-woven fabric, improving the practicality of the device.

[0021] Refer to Figure 1 and Figure 2As shown, the flattening mechanism includes two third support plates 17 arranged on one side of the connecting frame 5. Moving grooves are provided on the surfaces of the two third support plates 17. An electric telescopic rod three 18 is arranged inside the moving groove.

One end of the rotating shaft extends to the outside of the third support plate 17. One end of the rotating shaft is provided with a second motor 21. The output end of the second motor 21 is connected to the rotating shaft. The spunbond non-woven fabric is flattened by passing between the first rotating rod 19 and the second rotating rod 20, preventing a large number of wrinkles from appearing on the surface of the spunbond non-woven fabric, thereby affecting the effect of subsequent tension detection of the spunbond non-woven fabric. Moreover, the distance between the first rotating rod 19 and the second rotating rod 20 can be adjusted according to the thickness of the spunbond non-woven fabric. The electric telescopic rod three 18 drives the push block to move up and down, thus facilitating the adjustment of the distance between the first rotating rod 19 and the second rotating rod 20.

[0022] Referring Figure 3 and Figure 4 As shown, the adjusting mechanism includes moving grooves opened on the surfaces of the two first support plates 2. The two moving grooves are both slidably connected to the first slider 4. A lead screw 22 and a second sliding rod 23 are respectively arranged through the interiors of the two first sliders 4. A third motor 24 is arranged on the top of the first support plate 2. The output end of the third motor 24 is connected to the lead screw 22. An infrared detector 25 is arranged on one side of the first support plate 2. When the infrared detector 25 detects a large tension, the model of the infrared detector 25 is set to BTT-221. The third motor 24 drives the lead screw 22 to rotate. The lead screw 22 drives the tension adjusting roller 3 to move up and down through the first slider 4, adjusting the height distance between the tension adjusting roller 3 and the guide roller 14, thereby adjusting the tightening degree of the spunbond non-woven fabric and avoiding the tension of the spunbond non-woven fabric from becoming too large, resulting in rupture on the surface of the spunbond non-woven fabric.

[0023] The working principle of the present utility model: First, when the spunbond non-woven fabric is conveyed on the mounting plate 1, the electric telescopic rod one 6 inside the connecting frame 5 drives the first cleaning brush 7 to clean the upper surface of the spunbond non-woven fabric according to the thickness of the spunbond non-woven fabric. The second cleaning brush 8 on the surface of the mounting plate 1 cleans the lower surface of the spunbond non-woven fabric during its conveyance, so that the debris on the surface of the spunbond non-woven fabric can be conveniently processed. Then, the spunbond non-woven fabric is flattened by passing between the first rotating rod 19 and the second rotating rod 20, preventing a large number of wrinkles from appearing on the surface of the spunbond non-woven fabric, thereby affecting the effect of subsequent tension detection of the spunbond non-woven fabric. Moreover, the distance between the first rotating rod 19 and the second rotating rod 20 can be adjusted according to the thickness of the spunbond non-woven fabric. The electric telescopic rod three 18 drives the push block to move up and down, thus facilitating the adjustment of the distance between the first rotating rod 19 and the second rotating rod 20;

[0024] Then, the spunbond non-woven fabric is subjected to tension detection between the guide roller 14 and the tension adjustment roller 3. The first motor 13 drives the positive and negative screw rod 9 to rotate. The positive and negative screw rod 9 drives the second slider 11 to rotate. The second slider 11 drives the second support plate 12 to move left and right. It can also drive the second support plate 12 on the other side to drive the slider to move on the slide rod, thereby driving the mechanism between the second support plates 12 to move left and right. Then, the electric telescopic rod two 15 drives the baffle 16 to block the spunbond non-woven fabric according to its width on the guide roller 14, preventing the spunbond non-woven fabric from shifting during the conveying and testing of tension, enabling the device to adjust the distance between the tension adjustment roller 3 and the guide roller 14 according to the width and length of the spunbond non-woven fabric, improving the practicability of the device. When the infrared detector 25 detects that the tension is large, the model of the infrared detector 25 is set to BTT-221. The third motor 24 drives the lead screw 22 to rotate. The lead screw 22 drives the tension adjustment roller 3 to move up and down through the first slider 4, adjusting the height distance between the tension adjustment roller 3 and the guide roller 14, thereby adjusting the pressing degree of the spunbond non-woven fabric and avoiding the increase in the tension of the spunbond non-woven fabric, resulting in the rupture of the surface of the spunbond non-woven fabric.

[0025] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
