Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric winding technology, and in particular to an anti-friction winding mechanism for ultra-fine denier fiber nonwoven fabric. Background Technology

[0002] Ultrafine denier fibers typically refer to fibers with a denier of less than 0.55 dtex. The extremely fineness of these fibers is beneficial for improving the uniformity and strength of the resulting ultrafine denier nonwoven fabrics.

[0003] In the process of winding up microfiber nonwoven fabric, in order to improve the tightness of the winding, it is usually necessary to use a tensioning device to tension the microfiber nonwoven fabric, increase the friction between the microfiber nonwoven fabric and the tensioning device, thereby increasing the tension force, making the winding tighter, reducing looseness, and helping to reduce the volume of the packaged goods.

[0004] In actual production, the friction between the microfiber nonwoven fabric and the tensioning device is relatively large. On the one hand, this can easily lead to the breakage of some microfiber fibers. On the other hand, due to the characteristics of microfiber nonwoven fabric, the large friction can easily generate a lot of static electricity, attracting dust from the surrounding air and affecting the quality of the microfiber nonwoven fabric. Improvement is needed. Utility Model Content

[0005] The purpose of this invention is to provide a friction-resistant winding mechanism for ultra-fine denier fiber nonwoven fabric, used for winding ultra-fine denier fiber nonwoven fabric, ensuring the tightness of the winding and reducing friction problems.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A friction-resistant winding mechanism for ultra-fine denier nonwoven fabric includes: a base, a first support, a second support, a winding drum, a vacuum cleaner, a first air knife, and a second air knife. The first and second supports are spaced apart on the base. On the side of the first support facing the second support, a first guide roller and a second guide roller are spaced apart vertically. On the side of the second support facing the first support, a third guide roller and a fourth guide roller are provided, corresponding one-to-one with the first and second guide rollers. The winding drum is located on the top of the first support. The first air knife is located on the side of the first support and between the first and second guide rollers. The second air knife is located on the side of the second support and between the third and fourth guide rollers. The air outlet of the vacuum cleaner is provided with an air outlet pipe communicating with the first and second air knives.

[0008] The first bracket has a third air knife located on its side between the first air knife and the second guide roller, and the second bracket has a fourth air knife located on its side between the second air knife and the fourth guide roller. The vacuum cleaner's air intake is equipped with an air intake pipe that communicates with the third and fourth air knives.

[0009] The third and fourth air blades are arranged in a figure-eight shape.

[0010] The first and second air knives are arranged in a V-shape.

[0011] The first bracket has a fixed base on its outer side corresponding to the vacuum cleaner, and the vacuum cleaner is mounted on the fixed base.

[0012] The ultra-fine denier fiber nonwoven fabric is vertically passed upward between the second guide roller and the fourth guide roller, then wound onto the take-up drum.

[0013] The first bracket is equipped with a motor that drives the winding drum to rotate.

[0014] The beneficial effects of this utility model are as follows: A friction-resistant winding mechanism for ultra-fine denier fiber nonwoven fabric is provided. The ultra-fine denier fiber nonwoven fabric is conveyed and wound upwards. By increasing the vertical upward conveying stroke, tension is achieved using its own weight. A first air knife and a second air knife are specially designed to blow oblique downward airflow from both sides onto the surface of the ultra-fine denier fiber nonwoven fabric. This not only cleans the broken fibers on the surface of the ultra-fine denier fiber nonwoven fabric, but also increases the tension of the ultra-fine denier fiber nonwoven fabric, improving the tightness of the winding. Traditional tensioning devices are not required, thus reducing friction problems. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model;

[0016] Figure 2 yes Figure 1 A magnified view of part A in the middle. Detailed Implementation

[0017] The following is combined Figures 1 to 2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0018] like Figure 1 and Figure 2 The ultra-fine denier fiber nonwoven fabric anti-friction winding mechanism shown includes: a base 3, a first support 1, a second support 2, a winding drum 7, a vacuum cleaner 4, a first air knife 11, and a second air knife 12. The first support 1 and the second support 2 are arranged on the base 3 at intervals on the left and right, and can be fixed by welding or screws, resulting in a sturdy structure.

[0019] A first guide roller 6 and a second guide roller 15 are arranged vertically and vertically on the side of the first support 1 facing the second support 2. The vertical height difference between the first guide roller 6 and the second guide roller 15 is relatively large, which is beneficial to increase the vertical upward conveying stroke of the ultra-fine denier fiber nonwoven fabric.

[0020] On the side of the second bracket 2 facing the first bracket 1, there are a third guide roller 8 and a fourth guide roller 9 that correspond one-to-one with the first guide roller 6 and the second guide roller 15. The take-up drum 7 is located on the top of the first bracket 1. In this embodiment, the first bracket 1 is provided with a motor 16 that drives the take-up drum 7 to rotate. The motor 16 can be controlled by a PLC to adjust the rotation speed of the take-up drum 7.

[0021] like Figure 1 As shown, the ultra-fine denier fiber nonwoven fabric 10 is vertically conveyed and wound onto the take-up drum 7 after passing between the first guide roller 6 and the third guide roller 8, from between the second guide roller 15 and the fourth guide roller 9. This allows the ultra-fine denier fiber nonwoven fabric 10 to be conveyed and wound vertically upwards. By increasing the vertical upward conveying stroke, its own weight is effectively used for tensioning. The first guide roller 6, the second guide roller 15, the third guide roller 8, and the fourth guide roller 9 are only responsible for guidance and do not require a traditional tensioning device, thus reducing friction problems.

[0022] The first air knife 11 is disposed on the side of the first bracket 1 and located between the first guide roller 6 and the second guide roller 15, and the second air knife 12 is disposed on the side of the second bracket 2 and located between the third guide roller 8 and the fourth guide roller 9, as follows. Figure 2 As shown, the first air knife 11 and the second air knife 12 are distributed in a V-shape, blowing oblique downward airflow from both sides onto the surface of the ultra-fine denier nonwoven fabric 10. This not only cleans the broken fibers on the surface of the ultra-fine denier nonwoven fabric 10, but also increases the tension of the ultra-fine denier nonwoven fabric 10 and improves the tightness of the winding.

[0023] In addition, the third air knife 13 located on the side of the first support 1 and between the first air knife 11 and the second guide roller 15, and the fourth air knife 14 located on the side of the second support 2 and between the second air knife 12 and the fourth guide roller 9, are arranged in a figure-eight shape in this embodiment. They can draw in airflow from both sides of the ultra-fine denier fiber nonwoven fabric 10 downwards, further increasing the drape and tension of the ultra-fine denier fiber nonwoven fabric 10.

[0024] like Figure 1 As shown, the vacuum cleaner 4 has an air outlet with an air outlet pipe 5 that communicates with the first air knife 11 and the second air knife 12, and an air intake with an air intake pipe 18 that communicates with the third air knife 13 and the fourth air knife 14, for airflow circulation and filtration.

[0025] The first bracket 1 has a fixing seat 17 corresponding to the vacuum cleaner 4 on its outer side. The vacuum cleaner 4 is mounted on the fixing seat 17 and can be fixed with screws, making the structure stable.
