Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a nonwoven fiber opening device. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is composed of oriented or random fibers. It is a new generation of environmentally friendly material with characteristics such as moisture resistance, breathability, flexibility, light weight, non-combustibility, easy decomposition, non-toxicity and non-irritation, rich colors, low price, and recyclability. As a front-end equipment in a complete set of equipment for processing non-woven fabric products such as non-woven fabric and non-woven felt, the opening machine's main function is to open the raw materials obtained from market channels for the production of non-woven products.

[0003] A search revealed a Chinese patent disclosure for a nonwoven fabric opening machine (authorization announcement number CN211256173U), comprising a conveyor belt, a central gravity sensor at the end of the conveyor belt, an input shaft of a reducer connected to a drive shaft of an engine, a left gravity sensor on the left side of the central gravity sensor, a right gravity sensor on the right side of the central gravity sensor, an opening machine at the end of the central gravity sensor, and a controller electrically connected to the central gravity sensor, the left gravity sensor, the right gravity sensor, and the engine. This patented technology can instruct the controller to control the engine rotation, changing the position of the fabric falling onto the gravity sensor, thereby altering the distribution of the fabric.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that during the processing of nonwoven fabric opening machine, due to the light weight of the fibers, a lot of fiber material often gets wrapped around the opening roller, which easily causes accumulation. If the accumulated fibers are not cleaned in time, they can easily be rolled into the nonwoven fabric in subsequent processing, thus affecting the quality of the nonwoven fabric.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] Reference Figure 1-4 A nonwoven fabric fiber opening device includes an opening machine housing 1. An upper opening roller 3 is rotatably mounted inside the opening machine housing 1. A lower opening roller 12 is rotatably mounted inside the opening machine housing 1 and below the upper opening roller 3. Two fixed boxes 4 are fixedly installed inside the opening machine housing 1, respectively located on one side of the upper opening roller 3 and the lower opening roller 12. An air duct 16 is fixedly connected inside the fixed box 4. Dust suction holes 17 are arrayed inside the air duct 16. Scrapers 18 are fixedly connected to the outside of the air duct 16 on both sides of the dust suction holes 17. A dust suction fan 15 is fixedly installed on the outside of the opening machine housing 1. A dust collection box 14 is fixedly connected to the side. During the production of nonwoven fabric fibers, the nonwoven fabric fibers can be fed into the opening machine box 1 between the opening upper roller 3 and the opening lower roller 12 to achieve the opening treatment of the fibers. When a large amount of fiber material is wrapped around the surface of the opening upper roller 3 and the opening lower roller 12, the fibers on the opening upper roller 3 and the opening lower roller 12 can be scraped off by the scraper 18 on its surface through the air duct 16. The scraped fibers are then sucked into the air duct 16 by the dust suction fan 15 and finally sent into the dust collection box 14 so that the workers can process the fiber material and reduce the impact on subsequent nonwoven fabric processing, thus ensuring the production quality of nonwoven fabric.

[0028] Specifically, the rotating shaft of the upper opening roller 3 extends to the outside of the opening machine housing 1 and is fixedly connected to a second pulley 9. A pressing roller 5 is rotatably installed inside the opening machine housing 1. The rotation of the upper opening roller 3's rotating shaft drives the second pulley 9 to rotate, and the transmission belt 8 drives the first pulley 7 to rotate, thus enabling the pressing roller 5 to rotate. Through the use of the pressing roller 5, the non-woven fabric fibers on the feed plate 11 are fed into the opening machine housing 1, and the non-woven fabric fibers are squeezed. The rotating shaft of the pressing roller 5 extends to the outside of the opening machine housing 1 and is fixedly connected to a first pulley 7. The first pulley 7 and... A transmission belt 8 is connected between the second pulley 9 and the transmission belt 8. A servo motor 13 is fixedly installed on the outside of the opening machine housing 1 and above the dust collection box 14. The rotation of the output shaft of the servo motor 13 can drive the upper opening roller 3 to rotate, thereby realizing the transmission of power. The output shaft of the servo motor 13 extends into the interior of the opening machine housing 1 and is fixedly connected to the center of the upper opening roller 3. The dust collection fan 15 has two input ends and extends into the interior of the corresponding air duct 16. Through the above connection method, the normal conveying of non-woven fabric fibers can be ensured. The output end of the dust collection fan 15 extends into the interior of the dust collection box 14.

[0029] Specifically, a servo motor 10 is fixedly installed on one side of the opening machine housing 1. The output shaft of the servo motor 10 extends into the interior of the opening machine housing 1 and is fixedly connected to the rotating shaft of the lower opening roller 12. The rotation of the output shaft of the servo motor 10 can drive the lower opening roller 12 to rotate, thereby enabling it to work in conjunction with the upper opening roller 3 to open the nonwoven fabric fibers. The end of the scraper 18 away from the air duct 16 is in contact with the surfaces of the upper opening roller 3 and the lower opening roller 12. A cover 2 is hinged to the top of the opening machine housing 1 and above the upper opening roller 3. A feed plate 11 is fixedly connected to the outside of the opening machine housing 1. A door 6 is hinged inside the fixed box 4. The door 6 allows the operator to remove any remaining nonwoven fabric fibers that have fallen into the fixed box 4. A controller is externally connected to the outside of the opening machine housing 1, which can control the electrical equipment on the machine.

[0030] Working principle: First, during the production of nonwoven fabric fibers, the nonwoven fabric fibers are placed on the feed plate 11 and come into contact with the pressing roller 5. Then, the controller controls the servo motor 10, the servo motor 13, and the dust extraction fan 15 to drive them. The rotation of the upper opening roller 3 drives the second pulley 9 to rotate, and the transmission belt 8 drives the first pulley 7 to rotate, thereby realizing the rotation of the pressing roller 5. The rotation of the pressing roller 5 can wind the nonwoven fabric fibers on the feed plate 11 into the opening machine box 1, and the fibers are then wound into the opening machine box 1 by the rotation of the output shaft of the servo motor 10. The movement of the upper and lower opening rollers 12 can cause them to rotate, which in turn can be used in conjunction with the upper opening roller 3 to open the nonwoven fabric fibers. When a large amount of fiber material is wrapped around the surface of the upper and lower opening rollers 12, the fibers on the upper and lower opening rollers 12 can be scraped off by the scraper 18 on the surface of the air duct 16. The scraped fibers are then sucked into the air duct 16 by the dust suction fan 15 and finally sent into the dust collection box 14 so that the workers can process the fiber material and reduce the impact on subsequent nonwoven fabric processing, thus ensuring the production quality of the nonwoven fabric.
