Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of nonwoven fabric production equipment, specifically relating to a humidification device for nonwoven fabric production. Background Technology
[0002] During the production of nonwoven fabrics, especially in autumn and winter when the air humidity is low, the production line has a large amount of static electricity, which can easily cause abnormalities in the cotton web, such as "TCF cotton falling poorly" and "static adsorption of cotton web".
[0003] Currently, the common method is to humidify the entire production space. The disadvantages of this method are that the air humidity rises slowly, it is difficult to reach the inside of the machinery, and the anti-static effect is poor.
[0004] Chinese utility model patent CN202323574847.4 discloses an oiling and humidifying device for spinning and opening cotton, including a cotton storage box with a horizontal roller shutter and an inclined roller shutter inside; it also includes an oiling and humidifying assembly, which includes an oiling and humidifying pipe, a humidifier, and an adjusting pipe; one end of the oiling and humidifying pipe is connected to the spray nozzle of the humidifier, and the other end passes through the side wall of the cotton storage box and extends into its interior; the oiling and humidifying pipe is located above the horizontal roller shutter and arranged along the direction perpendicular to the horizontal roller shutter's conveying direction, corresponding to the feed end of the inclined roller shutter; spray holes are opened on the outer wall of the oiling and humidifying pipe corresponding to the horizontal roller shutter and / or the inclined roller shutter. The regulating tube has an open end and a closed end. The open end of the regulating tube moves into the interior of the oiling and humidifying tube from the other end. An air passage is opened on the outer wall of the regulating tube corresponding to the spray hole. The oiling and humidifying tube of this utility model is set inside the cotton storage box, which can quickly increase the humidity of the fibers. However, since the non-woven fibers are transported through the air pressure difference from the cotton storage box to the air pressure cotton box, the humidification mechanism set inside the cotton storage box may block the fibers. The fibers will be directly wrapped around the humidification mechanism after being wetted. At the same time, the humidification mechanism itself is difficult to clean and is easy to contaminate the fibers in the cotton storage box.
[0005] This utility model mainly designs a non-woven fabric humidification device that can increase the fiber humidity during the process from "cotton storage" to "pressure cotton box", thereby solving the problems of "TCF cotton falling poorly" and "electrostatic adsorption of cotton web"; and can also prevent the fibers from getting wet and getting tangled on the humidification mechanism.

[0026] Example 1
[0027] like Figures 1-2As shown, this embodiment provides a humidification device for nonwoven fabric production, including a cotton storage box 1 and a humidification device. A vent 2 is provided on the side wall of the output end of the cotton storage box 1. The humidification device is located outside the cotton storage box 1 and includes a humidifier 3. The outlet end of the humidifier 3 is connected to a humidification pipe 4. An air jet hole 5 is provided on the outer wall of the humidification pipe 4 facing the vent 2.
[0028] Specifically, in this embodiment, only one side wall of the cotton storage box 1 has ventilation holes 2. Preferably, the ventilation holes 2 are circular and located on the same horizontal plane, and the ventilation holes 2 are evenly distributed along the side wall of the output end of the cotton storage box 1. The corresponding humidification pipe 4 is also only provided on the same side of the cotton storage box 1, and the humidification pipe 4 is horizontally fixed below the ventilation holes 2 by a support device. See [reference needed] Figure 2 The image shows a top view of the humidification pipe 4. The humidification pipe 4 has air jet holes 5 on its outer wall facing the vent hole 2. Preferably, the distance between two adjacent air jet holes 5 is equal.
[0029] When in use, turn on the humidifier 3, and deliver humid air through the humidification pipe 4. The humid air is sprayed out through the jet hole 5 to the vent hole 2, and then enters the cotton storage box 1 through the vent hole 2.
[0030] The structure and working principle of the humidifier 3 are existing technologies and will not be described in detail in this embodiment.
[0031] Of course, the ventilation holes 2 are not limited to being set on one side of the cotton storage box 1. They can be set on both sides, three sides, or even around the perimeter of the cotton storage box 1. The corresponding humidification pipes 4 follow the ventilation holes 2 and are set below the ventilation holes 2.
[0032] The ventilation holes 2 can also be arranged at an angle on the outer wall of the cotton storage box 1, and the corresponding humidification pipes 4 are also arranged at an angle; the shape of the ventilation holes 2 can also be rectangular, elliptical, trapezoidal, etc., as long as it allows humid air to pass through.
[0033] Example 2
[0034] like Figures 3-5 As shown, this embodiment provides a humidification device for nonwoven fabric production, including a cotton storage box 1 and a humidification device. A vent 2 is provided on the side wall of the output end of the cotton storage box 1. The humidification device is located outside the cotton storage box 1 and includes a humidifier 3. The outlet end of the humidifier 3 is connected to a humidification pipe 4. An air jet hole 5 is provided on the outer wall of the humidification pipe 4 facing the vent 2.
[0035] For details, see Figure 3 and Figure 4In this embodiment, the vent 2 is circular and is evenly distributed along the circumference of the side wall of the output end of the cotton storage box 1; the corresponding humidification pipe 4 is arranged along the circumference of the side wall of the output end of the cotton storage box 1, and a branch pipe 7 is provided between the humidification pipe 4 and the outlet end of the humidifier 3, the branch pipe 7 connecting the humidification pipe 4 and the humidifier 3.
[0036] In practical applications, the humid air generated by the humidifier 3 is delivered to the jet hole 5 through the branch pipe 7 and the humidification pipe 4, and sprayed out towards the vent hole 2 on the cotton storage box 1. The humid air passes through the vent hole 2 and enters the interior of the cotton storage box 1, increasing the air humidity inside the cotton storage box 1 and achieving the effect of anti-static.
[0037] Furthermore, the spacing between two adjacent jet holes 5 is equal.
[0038] In one preferred embodiment, see Figure 4 and Figure 5 The figure shows a cross-sectional view of the cotton storage box 1, which also includes a flow guide 6. The flow guide 6 is disposed above the humidification pipe 4 and surrounds the air jet hole 5 and the air vent 2 in its inner space.
[0039] For details, see Figure 4 The flow guide shroud 6 is generally conical, including a vertical part 61 and an inclined part 62. One end of the vertical part 61 is connected to the humidification pipe 4, and the other end of the vertical part 61 is connected to one end of the inclined part 62. The other end of the inclined part 62 is connected to the cotton storage box 1.
[0040] The vertical part 61 is vertically installed on the outer periphery of the side wall of the cotton storage box 1, and the inclined part 62 is inclined between the vertical part 61 and the side wall of the cotton storage box 1. The guide hood 6 is cone-shaped and its inner diameter gradually narrows along the direction of the humid air spray, guiding the humid air to be accurately delivered to the vent 2. Through the setting of the guide hood 6, the humid air can be delivered to the inside of the cotton storage box 1 more accurately, reducing unnecessary waste of resources.
[0041] In another implementation, see Figure 5 The flow guide 6 is generally conical, including a vertical part 61 and an inclined part 62. One end of the vertical part 61 is a free end, and the other end of the vertical part 61 is connected to one end of the inclined part 62. The other end of the inclined part 62 is connected to the cotton storage box 1.
[0042] Among them, the flow guide 6 is directly fixed to the circumferential side wall of the cotton storage box 1, and is produced together during the production process. This design is more conducive to production and processing.
[0043] This utility model discloses a humidification device for nonwoven fabric production, comprising a cotton storage box 1 and a humidification device. Specifically, the output end of the cotton storage box 1 is provided with a vent 2. The humidification device is located outside the cotton storage box 1 and includes a humidifier 3. The outlet end of the humidifier 3 is connected to a humidification pipe 4, and the outer wall of the humidification pipe 4 facing the vent 2 is provided with an air jet vent 5. In use, the humid air generated by the humidifier 3 is sprayed out from the air jet vent 5, passes through the vent 2, and enters the interior of the cotton storage box 1, reducing the air humidity inside the cotton storage box 1 and achieving an anti-static effect. Since the interior space of the cotton storage box 1 is much smaller than the production operation space, its air humidity rises quickly, resulting in a good anti-static effect. The humidification device is located outside the cotton storage box 1 to prevent the fibers from getting wet and getting tangled on the humidification device. In addition, this utility model also provides a guide hood 6, which can accurately deliver humid air into the interior of the cotton storage box 1, further improving the anti-static effect.
[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
