Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, in particular to cooling equipment for hot air non-woven fabric production. Background Art

[0002] Nonwoven fabric is a kind of non-woven fabric. It is a new type of fiber product with soft, breathable and flat structure formed by directly using polymer chips, short fibers or filaments through various fiber web forming methods and consolidation technologies. Nonwoven fabric has many unique advantages, such as light weight, softness, environmental protection, recyclability, etc., so it is widely used in many fields such as medical, health, protection, packaging, home, agriculture and industry.

[0003] In the process of producing non-woven fabrics, high-temperature treatment is involved, such as hot-rolling bonding, so that the fibers can be firmly bonded together. However, if the non-woven fabrics after high-temperature treatment are directly processed or packaged, the microstructure of the fibers may change due to the residual heat, so the non-woven fabrics after heat treatment need to be cooled.

[0004] The existing technology usually uses an air cooler to cool non-woven fabrics. During long-term use observation, it was found that the cold air sent by the air cooler would accumulate condensed water, forming pollution, and the non-woven fabrics could not be cooled in a centralized manner, which would reduce the cooling effect on the non-woven fabrics and further reduce the quality of the non-woven fabrics.

[0032] Working principle: The starting device drives the air cooler 102 and the electric push rod 104 to be energized. After the air cooler 102 is energized, it will cool the air and send it into the air duct 103. The cold air will flow inside the air duct 103 and reach the air outlet plate 106. Then the cold air will be ejected from the inside of the air outlet plate 106 along the various air outlet holes 107. At the same time, the electric push rod 104 will make the cross plate 105 drop and approach the non-woven fabric. When the cross plate 105 drops, it will bring the air outlet plate 106 closer to the non-woven fabric. Therefore, when the cold air is ejected, it will flow inside the elastic fabric 108 until it reaches the surface of the non-woven fabric. After the cold air comes into contact with the non-woven fabric, it will take away the heat from the surface of the non-woven fabric and make the non-woven fabric The shape is quickly fixed; when cold air is ejected from the air outlet 107, the flowing airflow will cause the fan blades 22 to rotate, and the fan blades 22 will accelerate the airflow toward the non-woven fabric when rotating, which will cause the subsequent cold air to accelerate to flow toward the surface of the non-woven fabric under the action of the airflow when reaching the fan blades 22, thereby improving the cooling effect of the cold air on the non-woven fabric; when the device is started, cold air will be ejected from the air outlet 107 and reach the surface of the non-woven fabric, and the cold air will reach the surface of the second louver 33 during the flow process, and flow along the surface of the second louver 33 to the non-woven fabric. When the size of the processed non-woven fabric is inconsistent, the staff can turn the knob 34 to drive the rotating shaft 32 to rotate When the rotating shaft 32 rotates, it will drive the second louver 33 to rotate. When the angle of the second louver 33 changes, the flow direction of the cold air will also change accordingly. When the electric push rod 104 is started, the air outlet plate 106 will move closer to the non-woven fabric, and the air outlet plate 106 will drive the elastic cloth 108 closer to the non-woven fabric, and the elastic cloth 108 will drive the pressing plate 109 and the second connecting rod 4 closer to the non-woven fabric. The second connecting rod 4 will connect the slow flow plate 42 to move closer to the non-woven fabric until the slow flow plate 42 stays on the upper part of the non-woven fabric. At this time, the cold air will reach the top of the slow flow plate 42 after passing through the second louver 33, and then pass through the round hole 43 to reach the surface of the non-woven fabric. After taking away the heat of the non-woven fabric, the wind will reach the bottom of the slow flow plate 42, and then flow along the surface of the slow flow plate 42. During the flow, the cold air will continue to contact the non-woven fabric and cool the non-woven fabric; when the cold air flows inside the elastic fabric 108, the outside air will transfer heat to the inside of the elastic fabric 108 through the elastic fabric 108. Because the thermal insulation cotton 5 has the characteristic of low thermal conductivity, the thermal insulation cotton 5 will isolate the heat transmitted from the outside to the inside of the elastic fabric 108; when the non-woven fabric is processed, debris will be generated, and impurities such as dust will remain on the surface of the device. After cleaning, these impurities can be concentrated in the collection box 6, and the collection box 6 will collect these impurities;When the device stops working, the position of the collection box 6 can be slid and the pull plate 73 can be pulled. When the pull plate 73 moves, the pull rod 7 starts to slide and moves with the scraper 74. When the scraper 74 moves, it will rub against the surface of the support seat 1. The scraper 74 will rub and clean the surface of the support seat 1 to reduce dust and impurities on the surface of the support seat 1. At the same time, when the pull rod 7 slides, the spring 72 will be in a compressed state. The spring 72 will release the elastic force to reset the pull rod 7. When the scraper 74 resets, it will sweep the impurities into the interior of the collection box 6. ;
