[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-3 The present invention provides a technical solution: a deviation warning device for a composite nonwoven fabric production line, comprising a base plate 100, on both sides of the top of the base plate 100, nonwoven fabric conveying rollers 200 are vertically fixed, the nonwoven fabric conveying rollers 200 are used for conveying composite nonwoven fabric, and support columns 300 are vertically fixed at the front and back of the middle of the top of the base plate 100, the support columns 300 are vertically welded to the base plate 100, and a crossbeam 400 is connected between the tops of the support columns 300. A reversal warning component 500 is provided on the crossbeam 400, and a connecting component 600 is connected in the middle of the reversal warning component 500. Connecting rods 700 are slidably connected on both sides of the connecting component 600, and guide wheels 800 for limiting both sides of the composite nonwoven fabric are rotatably connected to the bottom of the connecting rods 700. The composite nonwoven fabric is conveyed on the nonwoven fabric conveying roller 200 and passes between the guide rollers 800. When the composite nonwoven fabric deviates, it causes the guide rollers 800 to shift. The early warning component 500 provides an early warning and promptly corrects the guide rollers 800 to correct the composite nonwoven fabric.

[0021] In use, the distance between the guide wheels 800 is first adjusted by the connecting component 600 to accommodate the width of the composite nonwoven fabric. Then, the composite nonwoven fabric is conveyed on the nonwoven fabric conveying roller 200 and passes through the guide wheels 800, making contact with them. During normal use, the composite nonwoven fabric is conveyed between the guide wheels 800 on the nonwoven fabric conveying roller 200. When the composite nonwoven fabric deviates, causing the guide wheels 800 to shift, the warning component 500 is adjusted to provide an early warning and promptly correct the guide wheels 800. This allows for simultaneous warning to personnel and timely correction without interrupting work, thus increasing work efficiency.

[0022] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The retraction warning component 500 includes a sliding groove 501 formed on the crossbeam 400, a slide rail 502 provided in the sliding groove 501, and the slide rail 502 fixed in the sliding groove 501 by screws. The slide rail 502 has an inverted convex cross-section, which can play a role in preventing falls. A slider 503 is slidably connected to the slide rail 502. The slider 503 has a groove that matches the slide rail 502. Positive electrodes 504 are embedded on both sides of the top of the slider 503. A negative electrode 505 is embedded in the inner side of the sliding groove 501 at the position corresponding to the positive electrode 504. (The figures in this application are for illustration only, and the actual implementation is different.) The length of the negative electrode 505 is the one-way mileage of the slide rail 502. One end of the crossbeam 400 is equipped with a warning light 506. When the slider 503 is not in the center of the slide rail 502, the positive electrode 504 and the negative electrode 505 are connected to make the warning light 506 energized and lit. The positive electrode 504, the negative electrode 505 and the warning light 506 form a circuit. A buzzer can also be used for warning. The specific choice should be made according to the specific use case. It is powered by an external power source. The slider 503 has a built-in adjustment structure, which is used to correct the misaligned composite nonwoven fabric.

[0023] When the composite nonwoven fabric shifts, the composite nonwoven fabric drives the slider 503 to move accordingly on the slide rail 502 via the guide wheel 800 and connecting rod 700. When the slider 503 moves left and right on the slide rail 502, it will cause the slider 503 to be out of the center of the slide rail 502, thereby causing the positive electrode 504 to contact the negative electrode 505. The external power supply powers the warning light 506, and the warning light 506 will light up to provide a warning and to correct the composite nonwoven fabric through the adjustment structure. The warning is given while the correction is performed.

[0024] Please see Figure 2 , Figure 4 , Figure 5 and Figure 6The adjustment structure includes a receiving groove 507 inside the slider 503. A bushing 508 is vertically rotatably connected at the middle position of the receiving groove 507. The bushing 508 is connected to the connecting assembly 600, which is located below the crossbeam 400. Rotating rods 509 are fixed obliquely on both sides of the bushing 508. A return spring 5010 is connected between the end of the rotating rod 509 and the inner side of the side arm of the slider 503. The return spring 5010 is made of stainless steel. The return spring 5010 is in a balanced state and is in a stretched state in its natural state. An elastic telescopic member is connected between the outer side of the side arm of the slider 503 and the sliding groove 501.

[0025] When a slight misalignment occurs, the composite nonwoven fabric drives the bushing 508 to rotate. The rotation of the bushing 508 causes the rotating rod 509 to rotate within the receiving groove 507. This causes the return springs 5010 on both sides of the rotating rod 509 to stretch on one side and compress on the other. Through the elastic force of the return springs 5010, the rotating rod 509 rotates in the opposite direction, thereby eliminating the direction of the misalignment of the composite nonwoven fabric and correcting it in time. When the composite nonwoven fabric has a large misalignment, not only will the above steps be repeated, but the slider 503 will also squeeze the elastic telescopic member on one side and stretch the elastic telescopic member on the other side. During correction, the elastic telescopic member will also provide elastic reset, so that the composite nonwoven fabric is corrected progressively without large changes, preventing overcorrection of the composite nonwoven fabric and the occurrence of folding in the misaligned part of the composite nonwoven fabric.

[0026] Please see Figure 5 and Figure 6 The elastic telescopic component includes a telescopic rod 5011 connected between the outer side of the slider 503 side arm and the sliding groove 501. The telescopic rod 5011 has a telescopic sleeve and a retractable extension rod, which is prior art and will not be described in detail here. A compression spring 5012 is sleeved on the outer side of the telescopic rod 5011. The compression spring 5012 is made of stainless steel and is initially in a compressed state.

[0027] In use, the sliding of the slider 503 can be limited to linear by using the telescopic rod 5011, and can be corrected in the case of elastic reset by using the compression spring 5012.

[0028] Please see Figure 3 and Figure 4The connecting component 600 includes an outer cover 601 located below the crossbeam 400. A connecting post 602, which is sleeved on the bushing 508, is vertically fixed at the top center of the outer cover 601. The connecting post 602 and the bushing 508 are fixedly connected and cannot rotate relative to each other. A moving groove 603 is provided inside the outer cover 601. A bidirectional screw 604 is rotatably connected in the moving groove 603. Nuts 606 are symmetrically threaded on both sides of the bidirectional screw 604. The nuts 606 are connected to the connecting rod 700. A drive component 605 is connected to the input end of the bidirectional screw 604. The drive component 605 is a bidirectional rotatable servo motor. The specific model is selected according to the actual use and is existing technology, so it will not be described in detail here.

[0029] In use, the drive unit 605 is activated according to the width of the composite nonwoven fabric. The rotation of the drive unit 605 drives the bidirectional screw 604 to rotate, thereby causing the two nuts 606 on it to move closer or further apart, which in turn causes the guide wheels 800 on the connecting rod 700 to move closer or further apart, thus adapting to composite nonwoven fabrics of different widths.

[0030] Among them, a gold hoop is provided between the outer side of the connecting column 602 and the inner side of the bushing 508 to prevent the connecting column 602 from falling off the inner side of the bushing 508.

[0031] Please see Figure 4 and Figure 7 The guide wheel 800 includes an intermediate wheel 802 located in the middle. Both the top and bottom ends of the intermediate wheel 802 are fixed with limit wheels 801. The diameter of the limit wheels 801 is larger than the diameter of the intermediate wheel 802. The top of the limit wheels 801 is fixed with a rotating column 803 that is rotatably connected to the connecting rod 700.

[0032] In use, the composite nonwoven fabric is restricted to the intermediate wheel 802 by the limiting wheel 801 to prevent the composite nonwoven fabric from changing position, and the use of the rotating column 803 can facilitate the overall rotation of the guide wheel 800.

[0033] The rotating column 803 and the connecting rod 700 are connected by a snap fastener.

[0034] During use, the snap-fit ​​connection allows for easy disassembly and installation of the rotating column 803, facilitating replacement.

[0035] The intermediate wheel 802 has a built-in protective soft pad, and the protective soft pad has a built-in spring.

[0036] When in use, the elasticity of the spring and the protection of the soft pad prevent scratches from occurring during the conveying of the composite nonwoven fabric.

[0037] The input end of the nonwoven fabric conveying roller 200 is connected to a drive motor to provide power to the nonwoven fabric conveying roller 200. It is powered by an external power source, and the outside of the nonwoven fabric conveying roller 200 is wrapped with a protective sleeve to protect the composite nonwoven fabric conveyed on it.
