Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and more specifically, to a combing device for nonwoven fabric processing. Background Technology

[0002] Nonwoven fabric is composed of oriented or random fibers and is a new generation of environmentally friendly material. It has the characteristics of being moisture-proof, breathable, flexible, lightweight, non-flammable, easily degradable, non-toxic and non-irritating, rich in color, inexpensive, and recyclable. It is made by directly using polymer chips, short fibers or filaments to form a web through airflow or mechanical means, and then reinforced by hydroentangling, needle punching or hot rolling. Finally, it is finished to form a non-woven fabric. After the nonwoven fabric is processed and formed, it needs to be wound up by a corresponding carding device.

[0003] Existing combing devices only promote the removal of fiber lint adhering to the surface of the brush roller through the toothed plate, but fail to promote the removal and recycling of fiber lint adhering to the toothed plate surface. This increases the number of subsequent cleaning steps and affects the subsequent scraping of fiber lint adhering to the brush roller by the toothed plate. Furthermore, the device fails to guide and recycle the floating fiber lint, which can easily cause air pollution.

[0004] A search revealed a Chinese patent with publication number CN222499516U that discloses a carding device for nonwoven fabric processing. This utility model incorporates a recycling component within the device. This recycling component uses an air extraction component, a conveying shell, and a receiving shell to extract air from the lower end of the toothed plate. The airflow passing through the toothed plate and brush roller guides the floating fiber lint while promoting the shedding of fiber lint adhering to the toothed plate surface. The rotating auger guides the fiber lint into the recycling box through the conveying shell and telescopic shell, thus achieving fiber lint recycling and preventing fiber lint from accumulating at the lower end of the toothed plate.

[0005] However, in actual use, the aforementioned carding device only scrapes one side of the nonwoven fabric surface with the toothed plate, which can only clean the impurities remaining on the surface of the nonwoven fabric, but cannot perform a relatively comprehensive cleaning of impurities on the nonwoven fabric, which will affect the processing quality of the nonwoven fabric. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a combing device for nonwoven fabric processing to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A carding device for nonwoven fabric processing includes a mounting frame. A carding machine body is mounted on one side of the mounting frame. Two rotating rollers are rotatably connected to the inner side of the mounting frame. Two servo motors are mounted inside the mounting frame. A gear is fixedly connected to the output end of each servo motor. A gear is meshed with one side of the gear. A pressure roller is fixedly connected to one side of the gear. The outer side of the pressure roller is rotatably connected to the inner side of the mounting frame. Two supports are fixedly connected to the inner side of the mounting frame. Two rotating rods are rotatably connected to the inner side of each support. A servo motor is fixedly connected to one end of each rotating rod. The outer side of the servo motor is fixedly connected to the inner side of the mounting frame. Multiple protruding rods are fixedly connected to the outer side of the rotating rod. A double collection mechanism is provided on the outer side of the mounting frame, and a support mechanism is provided on the inner side of the mounting frame.

[0008] By adopting the above technical solution: using two rotating rollers and a pressure roller to squeeze and convey the non-woven fabric, and at the same time using two rotating rods and a convex rod to beat and vibrate the conveyed non-woven fabric, so that the impurities remaining inside and outside the non-woven fabric are vibrated to the outside.

[0009] As a further description of the above technical solution: the dual collection mechanism includes two collection boxes. One side of each collection box is fixedly connected to the outside of the mounting frame. A filter screen is fixedly connected to the inside of each collection box. A fan is fixedly connected to the top of each collection box. Both the output and input ends of the fan are connected to air ducts. One end of one of the air ducts is fixedly connected to the inside of the collection box. A conveying pipe is fixedly connected to the top of the collection box. A top frame is fixedly connected to the top of the conveying pipe. Multiple baffles are fixedly connected to the inside of the top frame. Two servo motors are fixedly connected to the top of the top frame. Spiral blades are fixedly connected to the output ends of the servo motors. Multiple openings are provided on one side of each servo motor. One end of the top frame is connected to one end of one of the air ducts. Two duct fans are fixedly connected to the bottom of the mounting frame. A filter screen is fixedly connected to the inside of the mounting frame.

[0010] By adopting the above technical solution: using two fans and air ducts to suck the impurities above the non-woven fabric into the interior of the top frame through the top frame and baffle, and combining the servo motor three and spiral blades to spirally input the impurities accumulated inside the opening into the collection box for collection, and cooperating with two duct fans and filter two to perform negative pressure adsorption on the impurities at the bottom of the non-woven fabric.

[0011] As a further description of the above technical solution: the support mechanism includes two transmission rods, one side of which is rotatably connected to the inner side of the mounting frame, and two telescopic rods are slidably connected to the inner side of the transmission rods. Two electric cylinders are hinged to the outer side of the transmission rods, one end of which is hinged to the inner side of the mounting frame. One end of the telescopic rod is rotatably connected to a second rotating roller, and the outer side of the second rotating roller is slidably connected to the inner side of the mounting frame.

[0012] By adopting the above technical solution, the support force on the nonwoven fabric can be adjusted by raising and lowering the two rotating rollers, thus preventing the nonwoven fabric from bending and wrinkling.

[0013] The technical effects and advantages of this utility model are as follows: By setting up a dual collection mechanism, compared with the existing technology, the mechanical beating of multiple protruding rods moves the impurities inside the non-woven fabric to the surface. The upper and lower negative pressure dust collection can collect the dust and short fibers that are beaten out relatively comprehensively, preventing them from escaping into the air. This greatly reduces the impurity content in the finished product, achieves dual cleaning of the surface and the interior, and improves the product processing quality. By setting up a support mechanism, compared with existing technologies, the opposing lifting and lowering of two rotating rollers can adjust the support force, which can accurately compensate for the bending of the nonwoven fabric, ensure that the nonwoven fabric bears completely consistent pressure across the entire width, avoid wrinkles, and reduce material waste and downtime maintenance.

The rotating rod 10 and multiple protruding rods 11 are driven by the two servo motors 29 to beat the upper and lower sides of the nonwoven fabric, so that the dust on the inside and outside of the nonwoven fabric is separated and dispersed into the air. The two servo motors 14 and gear 15 mesh with gear 26 and pressure roller 7 to make the two pressure rollers 7 and rotating roller 13 squeeze and convey the nonwoven fabric.

[0023] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the dual collection mechanism includes two collection boxes 12. One side of the collection box 12 is fixedly connected to the outside of the mounting frame 1. A filter screen 13 is fixedly connected to the inside of the collection box 12. A fan 14 is fixedly connected to the top of the collection box 12. Both the output and input ends of the fan 14 are connected to air ducts 21. One end of one air duct 21 is fixedly connected to the inside of the collection box 12. A conveying pipe 15 is fixedly connected to the top of the collection box 12. A top frame 16 is fixedly connected to the top of the conveying pipe 15. Multiple baffles 17 are fixedly connected to the inside of the top frame 16. Two servo motors 18 are fixedly connected to the top of the top frame 16. A screw is fixedly connected to the output end of the servo motor 18. The rotating blade 19 and the servo motor 18 have multiple openings 20 on one side. One end of the top frame 16 is connected to one end of one of the air ducts 21. Two duct fans 22 are fixedly connected to the bottom of the mounting frame 1. A filter screen 23 is fixedly connected to the inside of the mounting frame 1. The two fans 14 and the air duct 21 are used to perform negative pressure dust suction inside the top frame 16. At the same time, the servo motor 18 and the spiral blade 19 are used to collect and transport the non-woven fabric collected under negative pressure, and to transport the impurities downward to the inside of the collection box 12 for collection. The two duct fans 22 and the filter screen 23 are combined to perform dust suction on the bottom of the non-woven fabric, so that the upper and lower sides of the non-woven fabric are collected under negative pressure.

[0024] Reference Figure 1 and Figure 5 As shown, the support mechanism includes two transmission rods 24. One side of the transmission rod 24 is rotatably connected to the inner side of the mounting frame 1. Two telescopic rods 27 are slidably connected to the inner side of the transmission rod 24. Two electric cylinders 25 are hinged to the outer side of the transmission rod 24. One end of the electric cylinder 25 is hinged to the inner side of the mounting frame 1. One end of the telescopic rod 27 is rotatably connected to a rotating roller 26. The outer side of the rotating roller 26 is slidably connected to the inner side of the mounting frame 1. By using multiple electric cylinders 25 to push the two transmission rods 24 and the telescopic rods 27 in opposite directions to deflect and push them, the two rotating rollers 26 can adjust the support force of the nonwoven fabric, effectively maintaining the flatness of the nonwoven fabric conveying.

[0025] The working principle of this utility model is as follows: When the nonwoven fabric is carded and processed by the carding machine body 2 and then wound up, one end of the nonwoven fabric passes between the rotating roller 3 and the pressure roller 7 on one side, and then the nonwoven fabric passes over two rotating rollers 26 respectively. After that, the nonwoven fabric is output between the rotating roller 3 and the pressure roller 7 on the other side, and then the nonwoven fabric is wound up by the external equipment. The two servo motors 4 are started to drive the gear 5 to mesh with the gear 6 on one side, so that the gear 6 drives the pressure roller 7 to rotate inside the mounting frame 1. The two pressure rollers 7 drive the rotating roller 3 to squeeze and flatten the nonwoven fabric. At the same time, the two electric cylinders 25 on the outside of the two transmission rods 24 extend and retract in opposite directions, so that the transmission rods 24 drive the two electric cylinders 25 to raise and lower the two rotating rollers 26. The two rotating rollers 26 can adjust the stretching and squeezing force of the nonwoven fabric. Then the two servo motors 4 are started to drive the gear 5 to mesh with the gear 6 on one side, so that the gear 6 drives the pressure roller 7 to rotate inside the mounting frame 1, so that the two pressure rollers 7 drive the rotating roller 3 to squeeze and flatten the nonwoven fabric. Servo motor 29 drives rotating rod 10 and multiple protruding rods 11 to rotate, so that the multiple protruding rods 11 can squeeze and beat the non-woven fabric conveyed between two rotating rollers 26, so that the residue adsorbed on the surface of the non-woven fabric is separated. Then, two fans 14 and air duct 21 are started to perform negative pressure dust suction on the inside of the top frame 16. At the same time, two duct fans 22 are used to perform negative pressure dust suction on the bottom of the mounting frame 1, so that the residue separated and dispersed into the air enters the inside of the top frame 16 and the surface of the filter screen 23 respectively. Then, the residue that enters the inside of the top frame 16 enters the inside of the two top frames 16 respectively. Then, the residue is filtered through multiple openings 20 on the inside of the two top frames 16. Finally, two servo motors 318 are started to drive spiral blades 19 to collect and convey the residue gathered inside the top frame 16 downwards, so that the residue enters the inside of the collection box 12 for collection.
