Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, specifically to a high-efficiency drying device for the production of antibacterial high-density nonwoven fabric. Background Technology

[0002] Antibacterial high-density nonwoven fabric is composed of fibers of a certain length randomly oriented. The nonwoven fabric undergoes a hydroentangling process during manufacturing, which causes the nonwoven fabric to become damp. To accelerate the drying speed of the nonwoven fabric, a drying device is needed to dry it.

[0003] For example, Chinese utility model patent CN207688569U discloses a nonwoven fabric drying box, comprising a box body, a hot air system, and a flattening mechanism. The left and right side walls of the box body have a discharge port and a feed port. Inside the box body are a first densely arranged steel wire mesh and a second densely arranged steel wire mesh, forming a nonwoven fabric channel between them. The two ends of the nonwoven fabric channel are connected to the discharge port and the feed port, respectively. Guide rollers are provided at the turning points of the nonwoven fabric channel. The hot air system includes a fan, an electric heater, and several air supply pipes. The fan is connected to the heater, and the heater is connected to each air supply pipe through the air supply pipes, which are installed on the upper and lower sides of the box body. The flattening mechanism is located at the discharge port and is used to squeeze and flatten the dried nonwoven fabric. This utility model has high drying efficiency, prevents hot air from directly blowing onto the nonwoven fabric, avoids deformation of the nonwoven fabric, and ensures the flatness of the nonwoven fabric.

[0004] The aforementioned authorized patent has the following problems in the process of drying nonwoven fabrics:

[0005] The nonwoven fabric travels in a "V" shape inside the drying oven, and the air supply pipe that vents the hot air is located in the middle of the "V". This causes the distance between the hot air discharged from the air supply pipe and the nonwoven fabric to be unequal, resulting in uneven drying of the nonwoven fabric and affecting its quality.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing drying equipment. Utility Model Content

The interior of the hot air outlet pipe 2 is provided with an inner cavity 5. Air jet holes 6 are provided at equal intervals on the inner side of the inner cavity 5. The air jet holes 6 are distributed at equal angles about the central axis of the inner cavity 5. The inner cavity 5 is connected to the second air outlet pipe 9. By starting the hot air blower 7, hot air can be ejected from the air jet holes 6.

[0026] A support plate 11 is fixed to the outer wall of the first air outlet pipe 8. The end of the support plate 11 is fixedly connected to the outer wall of the drying oven 1. The support plate 11 is symmetrically distributed about the central axis of the first air outlet pipe 8, which increases the stability of the first air outlet pipe 8.

[0027] The end of the hot air outlet pipe 2 passes through the side wall of the drying chamber 1 and is fixedly connected to the output end of the conveying device 14. The conveying device 14 can be a motor. The outer wall of the conveying device 14 is fixed to the side wall of the drying chamber 1 by bolts. The outer wall of the other end of the hot air outlet pipe 2 is nested and fixed with a pulley 12 away from the conveying device 14.

The sealed door is an existing product and can be opened and closed normally, allowing workers to enter the interior of the drying oven 1 to work.

[0031] Working Principle: When using this high-efficiency drying device for antibacterial high-density nonwoven fabric production, firstly, the sealed door is opened, and a worker enters the drying chamber 1. Then, another worker, outside the drying chamber 1, passes one end of the nonwoven fabric 4 between the second guide rollers 16, and then passes the other end of the nonwoven fabric 4 through the feed inlet into the drying chamber 1. Next, one end of the nonwoven fabric 4 passes through the bottom of the lowest position first guide roller 3. Then, the nonwoven fabric 4 is laid on the outside of several first guide rollers 3 above the lowest position first guide roller 3, with the several first guide rollers 3 above the lowest position first guide roller 3 located inside the nonwoven fabric 4, so that the nonwoven fabric 4 forms... Figure 3The shape of the nonwoven fabric 4 is such that, since the first guide roller 3 is distributed at equal angles with respect to the central axis of the hot air pipe 2, the nonwoven fabric 4 on several first guide rollers 3 above the lowest position first guide roller 3 is distributed in an arc shape. Then, one end of the nonwoven fabric 4 is passed through the bottom of another lowest position first guide roller 3. The nonwoven fabric 4 is then installed on another set of first guide rollers 3 according to the above operation. Finally, one end of the nonwoven fabric 4 is passed through the discharge port and another set of second guide rollers 16 and fixed on the winding equipment.

[0032] The winding setting is activated, causing the nonwoven fabric 4 to move inside the drying chamber 1. Then, the hot air blower 7 is activated, allowing hot air to enter the inner cavity 5 through the first air outlet pipe 8 and the second air outlet pipe 9. Finally, the hot air is sprayed onto the arc-shaped nonwoven fabric 4 through the air jet hole 6. Then, the conveying device 14 is activated, which drives the hot air outlet pipe 2, the inner cavity 5, and the air jet hole 6 to rotate, so that the arc-shaped nonwoven fabric 4 can be dried evenly. When the hot air outlet pipe 2 rotates, it drives another hot air outlet pipe 2 to rotate through the pulley 12 and the belt 13, drying another arc-shaped nonwoven fabric 4. This increases the drying distance of the nonwoven fabric 4 and improves the drying effect of the nonwoven fabric 4.
