Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, specifically relating to an auxiliary structure for edge-trimming fabric in a napping machine. Background Technology

[0002] The napping machine is an important machine widely used in the textile industry, but fabrics are prone to curling during napping operations. Traditional solutions require a motor-driven edge-trimming roller system, which includes complex components such as a motor, gearbox, frequency converter, belt drive mechanism, and angle adjuster (as described in the background section). Such systems have three major drawbacks:

[0003] 1. Requires an independent power source, has a complex structure, and occupies a large space;

[0004] 2. High failure rate and significant maintenance costs;

[0005] 3. Due to installation location limitations, some areas cannot deploy the equipment.

[0006] Therefore, there is an urgent need for a passive edge-trimming solution that requires no power input and has a compact structure. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a non-powered, adjustable fabric edge-trimming auxiliary structure that solves the edge-curling problem through purely mechanical design.

[0008] The objective of this utility model can be achieved through the following technical solution: A fabric edge-trimming auxiliary structure for a napping machine, characterized in that the mechanism includes a napping machine; a pair of mounting frames are symmetrically welded to the inner walls on both sides of the napping machine, and a first crossbar and a second crossbar are installed between the two mounting frames in a staggered manner. A pair of edge-trimming plates are provided on both the first crossbar and the second crossbar, and the edge-trimming plates on the first crossbar and the second crossbar are arranged opposite to each other; a number of inclined guide teeth are distributed on each edge-trimming plate, the fabric passes between the first crossbar and the second crossbar, and the edge-trimming plates on the first crossbar and the second crossbar are respectively in close contact with the two sides of the fabric; each edge-trimming plate is located near the edge of the fabric, and the guide teeth on each edge-trimming plate are inclined to both sides of the fabric along the direction of fabric conveying.

[0009] Preferably, both the first and second crossbars have strip-shaped through holes, and each side plate has several bolts fixed to its back. Each bolt is inserted into the corresponding strip-shaped through hole, and each bolt has a corresponding locking nut.

[0010] Preferably, each end of the first crossbar is fixed with two first guide posts and a first stud, with the first stud located between the two first guide posts. Each of the two mounting brackets has a first through hole corresponding to each of the first guide posts and the first stud. Each first guide post is fitted with a first spring, and each first spring abuts against the first crossbar and its corresponding mounting bracket. Each of the two mounting brackets has two second guide posts and a second stud fixed at positions corresponding to both ends of the second crossbar, with the second stud located between the two second guide posts. Each end of the second crossbar has a second through hole corresponding to each of the second guide posts and the second stud. Each second guide post is fitted with a second spring, and each second spring abuts against the second crossbar and its corresponding mounting bracket. Each of the first and second studs is threaded with an adjusting nut.

[0011] The advantages of this utility model are:

[0012] 1. Zero-power drive: No need for motors, gearboxes or other power components, reducing energy consumption.

[0013] 2. Space adaptability: It occupies less space and can be installed in small areas where traditional edge-trimming rollers cannot be deployed.

[0014] 3. Double-sided facing edge correction design: It can correct the curled edges of the fabric in different directions (two sides) to make them flat.

[0015] 4. Three-dimensional adjustable structure: The fabric edge coverage area can be adjusted horizontally through the strip-shaped through holes, and the pressure of the edge-pulling plate on the fabric can be adjusted vertically through the studs and springs.

[0016] 5. Staggered crossbar arrangement: to avoid mechanical interference and ensure unobstructed fabric passage.

[0017] 6. The adjusting nut, in conjunction with the spring, not only ensures that the edge-trimming plate always maintains elastic contact with the fabric, but also allows for quick changes in the mechanism, making it suitable for fabrics of different thicknesses. Attached Figure Description

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1 and Figure 2 As shown, a fabric edge-trimming auxiliary structure for a napping machine includes a napping machine 1; a pair of mounting frames 2 are symmetrically welded to the inner walls on both sides of the napping machine 1, and a first crossbar 3 and a second crossbar 4 are installed between the two mounting frames 2 in a staggered manner. Each of the first crossbar 3 and the second crossbar 4 is provided with a pair of edge-trimming plates 5, and the edge-trimming plates 5 on the first crossbar 3 and the second crossbar 4 are arranged opposite to each other; each edge-trimming plate 5 is provided with a number of inclined guide teeth 51, the fabric 6 passes between the first crossbar 3 and the second crossbar 4, and the edge-trimming plates 5 on the first crossbar 3 and the second crossbar 4 are respectively in close contact with the two sides of the fabric 6; each edge-trimming plate 5 is located near the edge of the fabric 6, and the guide teeth 51 on each edge-trimming plate 5 are inclined to both sides of the fabric 6 along the conveying direction of the fabric 6.

[0023] Working Principle: During the napping process, fabric 6 needs to travel between the conveyor rollers within the napping machine 1. This edge-pulling mechanism is located between two conveyor rollers. Fabric 6 passes through the gap between the first crossbar 3 and the second crossbar 4, and each edge-pulling plate 5 on the first crossbar 3 and the second crossbar 4 is in close contact with two sides of the edge of fabric 6. As fabric 6 travels, the curled edges pass over the edge-pulling plates 5. Guided by the guide teeth 51 on the edge-pulling plates 5, the curled edges are automatically smoothed and removed. This edge-pulling mechanism utilizes the fabric 6's own movement to smooth and remove the curled edges, requiring no additional power source, thus resulting in low manufacturing costs and energy efficiency. Furthermore, its simple structure and small footprint allow it to be installed in confined areas where traditional edge-pulling rollers cannot be deployed.

[0024] like Figure 1 and Figure 2 As shown, both the first crossbar 3 and the second crossbar 4 have strip-shaped through holes 7. Several bolts 52 are fixed to the back of each edge-pulling plate 5, and each bolt 52 is inserted into its corresponding strip-shaped through hole 7. Each bolt 52 has a corresponding locking nut 53. The cooperation between the strip-shaped through holes 7 and the bolts 52 and nuts allows the position of each edge-pulling plate 5 to be adjusted, thus making this mechanism applicable to fabrics 6 of different widths.

[0025] like Figure 1 and Figure 2As shown, two first guide posts 31 and first studs 32 are fixed at both ends of the first crossbar 3, with the first studs 32 located between the two first guide posts 31. Each of the two mounting brackets 2 has a first through hole corresponding to each of the first guide posts 31 and the first studs 32. Each first guide post 31 is fitted with a first spring 33, and each first spring 33 abuts against the first crossbar 3 and the corresponding mounting bracket 2. Two second guide posts 41 and second studs 42 are fixed at the corresponding ends of the second crossbar 4 on both mounting brackets 2, with the second studs 42 located between the two second guide posts 41. Each of the two ends of the second crossbar 4 has a second through hole corresponding to each of the second guide posts 41 and the second studs 42. Each second guide post 41 is fitted with a second spring 43, and each second spring 43 abuts against the second crossbar 4 and the corresponding mounting bracket 2. Each first stud 32 and each second stud 42 is threaded with an adjusting nut 8. The adjusting nut 8, in conjunction with the spring and the limiting effect of each guide post, not only ensures that the edge-trimming plate 5 always maintains elastic contact with the fabric 6, but also allows the mechanism to be quickly changed, making it suitable for fabrics 6 of different thicknesses.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
