Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a device for assisting fabric rehydration and cooling on an air softener. Background Technology

[0002] During the production of knitted fabrics using an air softener, the high-temperature air reduces the fabric's moisture content to almost 0%, and the fabric exits the machine at a relatively high temperature. Therefore, it needs to undergo cooling and rehumidification upon exiting the machine to ensure consistent quality. A uniform and stable rehumidification and cooling device is essential.

[0003] Currently, the main method is spray-based rehumidification, which involves multiple nozzles humidifying the fabric along the traction path. This method has the following problems:

[0004] 1. Water mist is sprayed onto the fabric using compressed air. However, the quality of the sprayed water mist is unstable due to changes in compressed air pressure, often resulting in water stains on the fabric.

[0005] 2. Compressed air spraying has a clear directionality; the area directly in front of the nozzle will have more moisture returning to its original position, while other areas will have less moisture returning, resulting in uneven moisture return.

[0006] 3. Single-sided humidification and cooling, along with uneven dot spraying, can easily cause color differences and curling tendencies between the two sides of the fabric. This is because water vapor penetrates slowly from one side of the fabric to the other, and the natural penetration inevitably causes differences in the distribution of water on both sides. This difference results in slight color differences between the two sides of the fabric and also affects the natural stretchability after the fabric tension is removed, thus forming a natural curling tendency. In subsequent processing, the natural curling tendency affects the orderliness of processes such as rolling and stacking, and is one of the reasons for fabric wrinkles. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention proposes a humidification and cooling device that can improve the uniformity of humidification.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a device for auxiliary fabric rehumidification and cooling on an air softener, characterized in that it includes a humidifying pipe fixed on the air softener frame and a guide tube rotatably connected to the air softener frame. The humidifying pipe has a flat water mist connector in the middle, the inlet of the water mist connector is constricted, the inlet of the water mist connector is connected to the air outlet of a water mist generator, a spiral guide vane is rotatably connected inside the humidifying pipe, one end of the spiral guide vane is connected to the output shaft of a motor, the guide tube is parallel to the humidifying pipe, the guide tube is densely covered with air holes, a through groove is opened on the pipe wall of the humidifying pipe near the guide tube, and the end of the guide tube is connected to a negative pressure air source.

[0009] Furthermore, the spiral guide vane has two sections, located on either side of the midpoint of the humidifying tube, with the spiral directions of the two sections being opposite. This ensures that the water mist can be distributed relatively evenly along the length of the humidifying tube, allowing the water mist to diffuse to both sides along the axial direction of the humidifying tube after entering from the middle position.

[0010] In this solution, firstly, the water mist outlet is strip-shaped, avoiding unevenness caused by point contact between the water mist and the fabric. Secondly, since the water mist outlet is changed from a small hole to a narrow groove, the escape velocity of the water mist will decrease due to the increase in the flow cross-section. Therefore, air holes are set on the guide tube that pulls the fabric and connected to a negative pressure air source. In this way, the guide tube can "adsorb" the water mist, increasing the flow velocity of the water mist, and also guiding the water mist to quickly penetrate from one side of the fabric to the other, so that the fabric is moistened on both sides and dissipates heat quickly. The heat dissipation method is changed from a single humidification heat dissipation to a combined method of humidification and air extraction. Therefore, the uniformity of water mist adhesion, double-sided penetration efficiency, and cooling effect are all optimized. Attached Figure Description

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 and Figure 2 As shown, it includes a humidifying pipe 1 fixed on the air softener frame and a guide tube 2 rotatably connected to the air softener frame. The humidifying pipe 1 has a flat water mist connector 3 in the middle. The inlet of the water mist connector 3 is constricted and connected to the air outlet of the water mist generator. A spiral guide vane 4 is rotatably connected inside the humidifying pipe 1. One end of the spiral guide vane 4 is connected to the output shaft of a motor 5. The guide tube 2 is parallel to the humidifying pipe 1 and has densely distributed air holes 6. A through groove 7 is opened on the pipe wall of the humidifying pipe 1 near the guide tube 2. The end of the guide tube 2 is connected to a negative pressure air source.

[0016] The spiral guide vane 4 has two sections, located on either side of the midpoint of the humidifying tube 1, with opposite spiral directions. This ensures that the water mist is evenly distributed along the length of the humidifying tube 1, allowing the water mist to diffuse laterally along the axis of the humidifying tube 1 after entering from the middle.

[0017] In this solution, firstly, the water mist outlet is strip-shaped, avoiding unevenness caused by point contact between the water mist and the fabric. Secondly, since the water mist outlet is changed from a small hole to a narrow groove, the escape velocity of the water mist will decrease due to the increase in the flow cross-section. Therefore, an air hole 6 is set on the guide cylinder 2 that pulls the fabric and is connected to a negative pressure air source. In this way, the guide cylinder 2 can "adsorb" the water mist, increasing the flow velocity of the water mist, and also can guide the water mist to quickly penetrate from one side of the fabric to the other side, so that the fabric is moistened on both sides and dissipates heat quickly. The heat dissipation method is changed from a single humidification heat dissipation to a combined method of humidification and air extraction. Therefore, the uniformity of water mist adhesion, double-sided penetration efficiency, and cooling effect are all optimized.

[0018] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
