Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a novel hot air setting device for nonwoven fabric. Background Technology

[0002] Nonwoven fabrics require hot air setting during production. Our patent application number 202223218704.5 discloses a nonwoven fabric hot air setting device, including a housing with a first partition inside. It also includes an upper and lower circular mesh roller with open ends and ventilated outer walls. The open ends of both rollers are rotatably connected to the first partition, and their other ends are rotatably connected to the housing and respectively driven by two first motors. Fan blades are respectively installed inside the open ends of the upper and lower circular mesh rollers, and the two fan blades are respectively connected to the shafts of two second motors. The lower cylinder drum is equipped with a ventilated heater on its exterior. The middle of both sides of the outer shell is provided with a feed port and a discharge port, respectively. A feed roller is provided on the upper part of the lower cylinder drum near the feed port, and a discharge roller is provided on the lower part of the upper cylinder drum near the discharge port. The length of the roller can be made shorter while maintaining the same heating path as existing technology. However, the fan blade is located at one end of the cylinder drum, which results in a much smaller air volume entering the drum through the drum wall at the end of the cylinder drum away from the fan blade compared to the end near the fan blade. This leads to a significant difference in the nonwoven fabric setting effect at both ends. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a novel hot air setting device for nonwoven fabrics, addressing the aforementioned technical deficiencies.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a novel non-woven fabric hot air setting device, including a shell, an upper circular mesh roller and a lower circular mesh roller with an opening at one end respectively rotatably connected to a partition provided inside the shell, and the other end respectively rotatably connected to the shell and respectively driven by two first motors, a fan blade driven by a second motor is provided inside the opening of the upper and lower circular mesh rollers, a heater is provided on the outside of the upper and lower circular mesh rollers, a feed port and a discharge port are provided on both sides of the shell, a feed roller is provided on the upper part of the lower circular mesh roller near the feed port, a discharge roller is provided on the lower part of the upper circular mesh roller near the discharge port, a wind hood is provided on the outside of the heater, one end of the wind hood is connected to a ventilation port on the partition, and the other end is provided with an air blowing port.

[0005] To further optimize this technical solution, baffles are provided on both sides of the wind shield cylinder.

[0006] To further optimize this technical solution, the wind hood outside the lower circular mesh roller gradually moves away from the lower circular mesh roller in the direction from approaching to moving away from the ventilation opening, and the wind hood outside the upper circular mesh roller gradually moves away from the upper circular mesh roller in the direction from approaching to moving away from the ventilation opening.

[0007] To further optimize this technical solution, an insulation layer is provided on the outside of the outer shell.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0013] Detailed implementation method: combined with Figure 1-2As shown, a novel nonwoven fabric hot air setting device includes a housing 1, an upper circular mesh roller 11, and a lower circular mesh roller 5 (both preferably made of perforated plates with breathable walls). One end of each roller has an opening and is rotatably connected to a partition 15 inside the housing 1; the other end is rotatably connected to the housing 1 and is driven by two first motors 12. Fan blades 13, driven by second motors 14, are respectively installed inside the openings of the upper and lower circular mesh rollers 11 and 5. Heaters 6 are respectively installed on the exterior of the upper and lower circular mesh rollers 11 and 5. The heaters 6 are breathable and extend in an arc shape in cross-section. The heater 6 outside the upper circular mesh roller 11 is coaxial with it, and its arc-shaped opening faces downwards. The heater outside the lower circular mesh roller 5... 6 is coaxial with it and the opening of the heater 6 in the arc-shaped extension shape faces upward. The two sides of the outer shell 1 are respectively provided with a feed port 3 and a discharge port 10. The upper part of the lower circular mesh roller 5 is provided with a cloth feeding roller 4 near the feed port 3. The two ends of the cloth feeding roller 4 are rotatably connected to the outer shell 1 and the partition plate 15 respectively. The lower part of the upper circular mesh roller 11 is provided with a cloth discharging roller 9 near the discharge port 10. The two ends of the cloth discharging roller 9 are rotatably connected to the outer shell 1 and the partition plate 15 respectively. The heater 6 is provided with a wind hood 8. The inside of the wind hood 8 is a cavity. One end of the wind hood 8 is connected to the ventilation port 16 on the partition plate 15, and the other end is provided with a blower 17. The blower 17 is located at the end of the upper circular mesh roller 11 or the lower circular mesh roller 5 away from the partition plate 15. The blower 17 can blow air towards the heater 6 at an angle. The air blown out of the air outlet 17 can improve the heat setting effect of the nonwoven fabric at the end away from the fan blade 13, thereby reducing the difference in the heat setting effect of the nonwoven fabric at both ends of the rotary drum.

[0014] Furthermore, baffles 7 are provided on both sides of the air hood 8. The baffles 7 extend in the direction of the heater 6 and the distance between them and the heater 6 is small, which can reduce the leakage of airflow to a certain extent, so that most of the airflow passes through the heater 6 and is blown onto the non-woven fabric outside the circular mesh roller.

[0015] Furthermore, the wind shield 8 outside the lower circular mesh roller 5 gradually moves away from the lower circular mesh roller 5 in the direction from near to far from the ventilation opening 16, and the wind shield 8 outside the upper circular mesh roller 11 gradually moves away from the upper circular mesh roller 11 in the direction from near to far from the ventilation opening 16, so that the air pressure blown out by the air outlet 17 is greater at the end of the circular mesh roller away from the ventilation opening 16 than at the end of the circular mesh roller near the ventilation opening 16, thereby further improving the heat setting effect of the nonwoven fabric at the end away from the fan blade 13.

[0016] Furthermore, an insulation layer 2 is provided on the outside of the outer shell 1.

[0017] In use, as with existing technology, the nonwoven fabric enters the interior of the outer casing 1 through the feed port 3, then passes over the feed roller 4 from above and passes down below the lower circular mesh roller 5 from its right side, then passes up from the right side of the lower circular mesh roller 5 and then to the left from the left side of the upper circular mesh roller 11, passing over the upper part of the upper circular mesh roller 11, then passes down from the right side of the upper circular mesh roller 11 from below the output roller 9, and then extends to the right from the output port 10. Heater 6 heats the gas, and fan blade 13 rotates to discharge the gas inside the two circular mesh rollers to the right. At the same time, external gas is drawn into the circular mesh rollers through the outer wall of the rollers and the non-woven fabric outside the outer wall. The gas between the right side of partition 15 and the outer shell 1 enters the wind hood cylinder 8 through vent 16 and is blown out through air outlet 17. The air blown out through air outlet 17 passes through heater 6, non-woven fabric and the cylinder wall of the circular mesh rollers and enters the inside of the rollers for circulation. At the same time, the two circular mesh rollers rotate continuously to move the non-woven fabric. During this process, the non-woven fabric is heated, and the bonding material in it melts, bonding the fibers in the non-woven fabric together.

[0018] The specific embodiments described above do not constitute a limitation of this utility model. Any modifications, equivalent substitutions, or improvements made to the above embodiments should be included within the protection scope of this utility model.
