Abstract
Description

The drawing process, as a key step in spunbond nonwoven fabric production, directly affects the fiber orientation, thickness uniformity, and mechanical properties of the nonwoven fabric. Through drawing, the nonwoven fibers can be fully stretched, thereby improving the product's strength and toughness and ensuring product quality. At the same time, the recycling function of the drawing system helps optimize resource allocation, reduce energy consumption and production costs, and meets the industrial requirements of sustainable development.

[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.
[0021] To address the problems existing in the background technology, this application proposes the following technical solution: a spunbond nonwoven fabric drafting system recycling device, comprising a frame 1, the frame 1 having multiple sets of mounting holes, and fixed frames 2 fixedly connected to both sides of the top of the frame 1. A first traction roller 3 and a second traction roller 4 are provided outside the fixed frames 2. A first rotating rod 5 is fixedly connected to the outside of the first traction roller 3, and a second rotating rod 6 is fixedly connected to the outside of the second traction roller 4. A sliding opening 7 is provided in the fixed frame 2, and a slider 9 is slidably connected in the sliding opening 7. Both the sliding opening 7 and the slider 9 are rectangular structures. Limiting plates are fixedly connected to both sides of the top of the slider 9, and the limiting plates abut against the outside of the sliding opening 7. The second rotating rod 6 is rotatably connected to the slider 9. A pulley transmission assembly is provided outside the first rotating rod 5 and the second rotating rod 6. An adjustment assembly for adjusting the pulley transmission assembly is also provided outside the fixed frame 2. The frame 1 serves as the basic support structure for the entire drafting system recycling device, and the multiple sets of mounting holes on it greatly facilitate the installation and fixing of the equipment. These mounting holes can accommodate bolts, nuts, and other connectors of different specifications, allowing the frame 1 to be securely installed on the ground, wall, or other supporting structures according to the layout and needs of the actual production site. This ensures that the equipment will not shift or shake due to vibration, external forces, or other factors during operation, laying a solid foundation for the stable operation of the entire drafting system. The mounting brackets 2 on both sides of the top of the frame 1 provide mounting carriers for the first traction roller 3 and the second traction roller 4, which are the core components for the drafting and conveying of nonwoven fabric. The first traction roller 3 and the second traction roller 4 are connected to the pulley drive assembly through the first rotating rod 5 and the second rotating rod 6, forming a complete power transmission system.
[0022] The rectangular sliding opening 7 and slider 9 are not only easy to manufacture, but also ensure good stability and guidance for the slider 9 when sliding within the sliding opening 7, effectively preventing the slider 9 from shifting or jamming during sliding. The limiting plates on both sides of the top of the slider 9 can tightly abut against the outside of the sliding opening 7, limiting the sliding range of the slider 9 while further enhancing the fixing effect of the slider 9 on the fixed frame 2, preventing the slider 9 from detaching from the sliding opening 7 due to vibration or other factors during equipment operation, and ensuring the stability of the installation position of the second traction roller 4. The rotating connection between the second rotating rod 6 and the slider 9 allows the second traction roller 4 to maintain flexible rotation while moving up and down with the slider 9, providing feasibility for subsequently changing the height of the second traction roller 4 by adjusting the position of the slider 9, thereby meeting the diverse needs of different production processes for the nonwoven fabric drafting height.
[0023] In this embodiment, the pulley drive assembly includes a first pulley 10, a second pulley 11, and a third pulley 13. The first pulley 10 is fixedly connected to the second rotating rod 6. One end of the first rotating rod 5 passes through the fixed frame 2 and is fixedly connected to the second pulley 11. A movable frame 12 is provided outside the fixed frame 2. The third pulley 13 is rotatably connected to the movable frame 12. A belt 14 is sleeved on the outside of the first pulley 10, the second pulley 11, and the third pulley 13. The pulley drive assembly adopts a structure in which the first pulley 10, the second pulley 11, and the third pulley 13 are combined with the belt 14 for transmission, which has significant advantages such as smooth transmission, low noise, and easy maintenance. The first pulley 10 is fixedly connected to the second rotating rod 6, and the second pulley 11 is connected to the first rotating rod 5. This connection method can ensure that the power is efficiently transmitted from the first rotating rod 5 to the second rotating rod 6, thereby driving the first traction roller 3 and the second traction roller 4 to rotate synchronously, realizing stable stretching and conveying of nonwoven fabric. The rotating connection design between the third pulley 13 and the movable frame 12 allows the position of the third pulley 13 to be flexibly adjusted according to actual needs.
[0024] In actual production, adjusting the position of the moving frame 12 changes the position of the third pulley 13, effectively adjusting the tension of the belt 14 and the transmission path. When it is necessary to increase the tension of the belt 14, the third pulley 13 can be moved away from the first pulley 10 and the second pulley 11 to tighten the belt 14 and ensure the stability of power transmission; conversely, when it is necessary to decrease the tension or adjust the transmission angle, the third pulley 13 can be moved closer to the first pulley 10 and the second pulley 11. This flexible adjustment method can adapt to the production needs of nonwoven fabrics of different thicknesses and materials, avoid slippage caused by the slack of the belt 14, ensure uniform stress on the nonwoven fabric during the stretching process, and effectively improve product quality.
[0025] In this embodiment, the adjustment assembly includes an electric push rod 8 and a threaded rod 15. The output end of the electric push rod 8 is fixedly connected to the slider 9. A motor is fixedly connected to the outside of the fixed frame 2, and the output end of the motor is fixedly connected to the threaded rod 15. The threaded rod 15 is threadedly connected to the movable frame 12. A guide rod 16 is fixedly connected to the outside of the fixed frame 2, and the guide rod 16 passes through the movable frame 12. The adjustment assembly includes cylinders 17 fixedly connected to both sides of the fixed frame 2. The output end of the cylinder 17 is fixedly connected to a mounting base, and an abutment wheel 18 is rotatably connected in the mounting base. The abutment wheel 18 corresponds to the belt 14. The design of the adjustment assembly fully considers the diverse needs for adjusting equipment parameters during the nonwoven fabric production process. Through the coordinated work of components such as the electric push rod 8, threaded rod 15, motor, guide rod 16, cylinder 17, and abutment wheel 18, precise adjustment of the belt drive assembly and effective control of the belt 14 state are achieved. The fixed connection between the electric push rod 8 and the slider 9 makes the height adjustment of the second traction roller 4 simple and efficient. The operator only needs to activate the electric push rod 8 through the control system. The electric push rod 8 will drive the slider 9 to slide up and down within the sliding opening 7, thereby achieving precise adjustment of the height of the second traction roller 4. Compared with the traditional manual adjustment method, this electric adjustment method has the advantages of fast adjustment speed, high precision, and simple operation. It can quickly adapt to the requirements of different production processes on the nonwoven fabric stretching height and improve production efficiency.
[0026] The motor drives the threaded rod 15 to rotate, which in turn drives the movable frame 12 to move along the guide rod 16 via the threaded transmission principle, thereby adjusting the position of the third pulley 13. The guide rod 16 provides stable guidance for the movement of the movable frame 12, ensuring that the movable frame 12 will not deviate during movement and guaranteeing the accuracy and stability of the adjustment of the third pulley 13. This adjustment method can precisely control the tension and transmission angle of the belt 14, meeting the parameter requirements of the belt 14 transmission system during the production of nonwoven fabrics of different specifications. The combination of the cylinders 17 and the abutment wheels 18 on both sides of the fixed frame 2 further enhances the control capability over the state of the belt 14. When it is necessary to keep the belt 14 taut, the cylinder 17 pushes the mounting base and the abutment wheel 18 forward, so that the abutment wheel 18 presses tightly against the outside of the belt 14. The pressure of the abutment wheel 18 keeps the belt 14 taut and at the same time causes the belt 14 to fully wrap around the first pulley 10, the second pulley 11 and the third pulley 13, ensuring the stability and reliability of the belt 14 transmission and effectively avoiding problems such as belt slippage and deviation.
[0027] The usage method of this embodiment is as follows:
[0028] After fixing the device, the first rotating rod 5 is fixedly connected to the output end of the external drive motor through a flange connection (one end of the first rotating rod 5 extends to the outside of the second pulley 11).
[0029] The first rotating rod 5 is driven by the drive motor to rotate, the first rotating rod 5 drives the first traction roller 3 to rotate, the first traction roller 3 drives the second pulley 11 to rotate, and through the transmission of the belt 14, the second traction roller 4 can be driven to rotate, thereby traction and conveying the non-woven fabric on the traction roller.
[0030] When it is necessary to adjust the height of the second traction roller 4, simply start the motor to drive the threaded rod 15 to rotate. The threaded rod 15 drives the moving frame 12 to move, and the moving frame 12 drives the third pulley 13 to move. When the third pulley 13 moves in the horizontal direction of the first pulley 10, the first pulley 10 can be raised; conversely, the first pulley 10 can be lowered. The lifting and lowering adjustment of the second traction roller 4 and the first pulley 10 can be controlled by pushing the slider 9 through the electric push rod 8.
[0031] Additionally, the movement of cylinder 17 can be controlled so that the contact wheel 18 contacts the outside of belt 14, which allows belt 14 to remain taut while fully wrapping the first pulley 10, the second pulley 11, and the third pulley 13.
[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] Although embodiments of the present invention have been shown and described, the scope of the present invention will be defined by the appended claims and their equivalents for those skilled in the art.
