Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to a nonwoven fabric web forming machine that prevents airflow interference. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, is composed of oriented or randomly arranged fibers. Nonwoven fabric is typically produced using polypropylene granules as raw material, through a continuous one-step process involving high-temperature melting, spinning, laying, and hot-pressing.

[0003] In the production of nonwoven fabrics, the raw materials need to be spun and shaped before further processing. A nonwoven fabric web-forming machine is used for the web-forming process. This machine uses airflow in a drawing duct to draw the filaments and then weaves them into a web in a non-directional manner. However, polypropylene granules are prone to filament breakage and clumping during the drawing, stretching, and web-forming processes. Therefore, to improve the quality of the finished nonwoven fabric, it is necessary to clean the formed nonwoven fabric.

[0004] When traditional web forming machines handle broken filaments and lumps, workers typically clean them from behind the machine with brushes or scouring pads. However, because the conveyor belt of the web forming machine is quite wide and moves at a high speed, the cleaning area that workers can cover is limited, resulting in low cleaning efficiency and consequently affecting the quality of the finished nonwoven fabric.

[0005] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0033] like Figures 1-7 As shown, this embodiment proposes a nonwoven fabric web forming machine to prevent airflow interference, including...

[0034] The web forming machine body 1 and the conveyor belt 2 are located at the bottom of the web forming machine body 1;

[0035] A pair of extension frames 3 and a conveying and compacting component 4 are provided. The extension frames 3 are fixed to the outer end of the web forming machine body 1, and the conveying and compacting component 4 is arranged between the extension frames 3.

[0036] Cleaning component 5 is located inside the extension frame 3;

[0037] The conveying and compacting assembly 4 includes a pair of conveying rollers 4-1, both of which are rotatably connected between the extension frames 3. Each conveying roller 4-1 has a transmission gear 4-2 at one end, and the transmission gears 4-2 mesh with each other. One of the conveying rollers 4-1 is controlled to rotate by a motor. A support plate 4-3 is fixedly connected between the extension frames 3, and a cross frame 4-4 is fixedly connected between the extension frames 3. Several movable rods 4-5 are movably fitted inside the cross frame 4-4. A compaction plate 4-6 is provided at the lower end of the movable rod 4-5, and a pressure plate 4-7 is movably fitted at the lower end of the movable rod 4-5. A spring 4-8 is fitted on each of the movable rods 4-5. A fixing block 4-9 is provided on the extension frame 3, and a stud 4-10 is connected inside the fixing block 4-9 by a threaded connection. Both ends of the surface of the cross frame 4-4 are provided with round openings 4-11. A pressure block 4-12 is provided at the lower end of the stud 4-10, and the lower end face of the pressure block 4-12 is attached to the surface of the pressure plate 4-7.

[0038] In this embodiment, to achieve the effect of conveying the formed nonwoven fabric outward while simultaneously making it more compact, a conveying and compacting component 4 is designed. Two conveying rollers 4-1 are rotatably connected between the extension frames 3, and each is equipped with a transmission gear 4-2. One of the conveying rollers 4-1 is controlled to rotate by a motor, allowing both conveying rollers 4-1 to rotate synchronously and convey outward. A support plate 4-3, a compaction plate 4-6, and two fixing blocks 4-9 are also fixed. Multiple movable rods 4-5 are movably fitted inside the compaction plate 4-6 and connected to the lower end of the compaction plate 4-6. The compaction plate 4-6 is in contact with the surface of the support plate 4-3, and... A spring 4-8 is fitted onto the movable rod 4-5. The spring force of the spring 4-8 can generate pressure on the compaction plate 4-6 to compact the non-woven fabric. A pressure plate 4-7 is also fitted onto the movable rod 4-5. A stud 4-10 is threadedly connected to the fixing block 4-9. A round opening 4-11 is opened on the surface of the crossbeam 4-4 located directly below the stud 4-10. A pressure block 4-12 is set at the lower end of the stud 4-10. The stud 4-10 can be turned to press the pressure block 4-12 against the surface of the pressure plate 4-7. The pressure plate 4-7 descends, which increases the spring force of the spring 4-8 and increases the pressure of the compaction plate 4-6.

[0039] Furthermore, the cleaning assembly 5 includes a pair of cleaning rollers 5-1, both of which are rotatably connected between the extension frames 3. Each of the cleaning rollers 5-1 has a second gear 5-2 at one end, and the second gears 5-2 mesh with each other. An outer cover 5-3 and a vacuum fan 5-4 are provided on the outer surface of the extension frame 3. The suction end of the vacuum fan 5-4 is connected to the outer cover 5-3. A pair of air collection hoods 5-5 are provided between the extension frames 3. The air collection hoods 5-5 are located outside the cleaning rollers 5-1. Several air collection holes 5-6 are opened on the inner surface of the air collection hoods 5-5. A pair of bonding plates 5-7 are provided between the extension frames 3.

[0040] In this embodiment, a cleaning component 5 is designed to achieve the effect of cleaning the surface of the non-woven fabric. Two cleaning rollers 5-1 and a second gear 5-2 are rotatably connected between the extension frames 3. The cleaning rollers 5-1 are rotated by a motor, and the two cleaning rollers 5-1 can rotate synchronously through the second gear 5-2. An outer cover 5-3 and a dust collection fan 5-4 are provided on the surface of one side of the extension frame 3. Two dust collection hoods are connected between the extension frames 3. The dust collection hoods are connected to the air collection hoods 5-5, and multiple air collection holes 5-6 are opened on the inner surface of the dust collection hoods. The air collection holes 5-6 can generate suction to absorb foreign objects cleaned by the cleaning rollers 5-1. A bonding plate 5-7 is also provided. The bonding plate 5-7 can make the non-woven fabric fit the cleaning rollers 5-1 better, resulting in a better cleaning effect.

[0041] Furthermore, the surface of the conveyor roller 4-1 is a non-slip structure made of rubber.

[0042] In this embodiment, the anti-slip effect of the conveying roller 4-1 can be increased by the rubber material structure surface, making the conveying more stable.

[0043] Furthermore, both ends of the compaction plate 4-6 are bent upwards, and the bent ends of the compaction plate 4-6 and the ends of the support plate 4-3 are arc-shaped transition structures.

[0044] In this embodiment, the upward-bending transition structure prevents damage to the nonwoven fabric during insertion and removal.

[0045] When processing is required, the web forming machine body 1 conveys the nonwoven fabric outward. The nonwoven fabric passes between the compaction plate 4-6 and the support plate 4-3 and between the conveying rollers 4-1. The conveying rollers 4-1 are started to convey the fabric outward. At the same time, the cleaning rollers 5-1 and the dust extraction fan 5-4 are started. When cleaning, the cleaning rollers 5-1 suck up foreign objects through the air collection holes 5-6 and collect them. Then, when conveying the fabric outward, the pressure plate further compacts the nonwoven fabric. If it is necessary to increase the pressure, the studs 4-10 can be turned to move the pressure plate 4-7 downward to increase the pressure of the spring 4-8.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
