Description

Technical Field

[0001] This utility model belongs to the field of medical dressing production equipment, and specifically relates to a spunlace nonwoven fabric roll drying equipment. Background Technology

[0002] Traditional spunlace nonwoven fabric drying equipment often fails to achieve efficient drying results in practical applications. Some equipment uses only a single drying structure, resulting in insufficient contact between the spunlace nonwoven fabric and the heat source, leading to long drying times and high energy consumption. For example, some early equipment relied solely on simple hot air blowing, which could not achieve comprehensive and deep drying of the spunlace nonwoven fabric, resulting in excessively high product moisture content, affecting product quality and subsequent processing performance.

[0003] Traditional equipment also has significant shortcomings in terms of dehumidification. If the hot and humid gases generated during the drying process cannot be discharged in time, they will accumulate inside the equipment, leading to increased internal humidity and reduced drying efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a spunlace nonwoven fabric roll drying equipment. By setting a rotatable drying cylinder, a reasonably arranged air outlet component, and an optimized hot air conveying and dehumidification system, it solves the technical problems of low drying efficiency, poor dehumidification, and poor coordination between conveying and drying of spunlace nonwoven fabric in traditional equipment, and achieves efficient and high-quality drying of spunlace nonwoven fabric.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A spunlace nonwoven fabric roll drying device includes a drying oven, characterized in that: the drying oven is rotatably provided with a mesh drying cylinder, an air outlet component is provided next to the mesh drying cylinder, and a spunlace nonwoven fabric passing through gap is provided between the air outlet component and the mesh drying cylinder;

[0007] The mesh drying cylinder is connected to the hot air conveying device, and the air outlet component is connected to the dehumidification pipe.

[0008] Preferably, the air outlet component is an air outlet duct, which has arc-shaped mesh holes arranged facing the drying cylinder.

[0009] Preferably, there are multiple mesh drying cylinders, and each mesh drying cylinder is equipped with a corresponding air outlet component.

[0010] Preferably, multiple spunlace nonwoven fabrics are arranged linearly, and the spunlace nonwoven fabric passes through the gaps between the multiple spunlace nonwoven fabrics in an S-shaped path.

[0011] Preferably, the hot air conveying device includes a hot air conveying pipe, which is connected to a heat source and to a wire mesh drying cylinder for supplying hot air to the cylinder.

[0012] Preferably, the exhaust duct uses a negative pressure fan to expel the hot and humid gas.

[0013] Preferably, the drying cylinder is driven by a drive motor to rotate, thereby driving the spunlace nonwoven fabric transmission.

[0014] The present invention can achieve the following beneficial effects:

[0015] 1. This invention utilizes a linear arrangement of multiple drying cylinders, with the spunlace nonwoven fabric passing through the gaps in an S-shape, significantly increasing the contact time and area between the spunlace nonwoven fabric and the heat source. Compared to traditional single-structure drying equipment, drying efficiency is greatly improved.

[0016] 2. This utility model features an air outlet duct equipped with an arc-shaped mesh facing the drying cylinder. Combined with a negative pressure fan and dehumidification pipe design, it can quickly and efficiently expel the humid and hot gas generated during the drying process. Compared with traditional dehumidification systems, it maintains a good drying environment, ensures that drying efficiency is not affected by humidity, and achieves continuous and stable operation of the drying process.

[0022] Preferred solutions include Figures 1 to 3 As shown, a spunlace nonwoven fabric roll drying device includes a drying oven 1, a rotatable drying cylinder 2, an air outlet component next to the drying cylinder 2, and a spunlace nonwoven fabric passing gap 3 between the air outlet component and the drying cylinder 2; the spunlace nonwoven fabric passing gap 3 is used for the passage of the spunlace nonwoven fabric, providing space for the drying process.

[0023] The drying cylinder 2 is connected to the hot air conveying device, and the air outlet component is connected to the dehumidification pipe 4. The hot air conveying device is responsible for delivering hot air to the drying cylinder 2, achieving drying of the spunlace nonwoven fabric through heat conduction. Simultaneously, the air outlet component is connected to the dehumidification pipe 4 to discharge the hot and humid gas generated during the drying process, maintaining a dry environment within the equipment and ensuring drying efficiency.

[0024] Furthermore, the air outlet component is an air outlet duct 5, which has arc-shaped mesh holes 501 arranged facing the drying cylinder 2. The arc-shaped mesh holes 501 are arranged in the direction facing the drying cylinder 2. This structural design can quickly discharge hot and humid gas and optimize the drying effect.

[0025] Furthermore, there are multiple drying cylinders 2, each with a corresponding air outlet component. Multiple drying cylinders 2 not only increase the drying effect but also facilitate the transmission of the spunlace nonwoven fabric 8 by rotating the drying cylinders 2.

[0026] Furthermore, multiple drying cylinders 2 are arranged linearly, and the spunlace nonwoven fabric passes through the multiple spunlace nonwoven fabric passage gaps 3 in an S-shaped path. This layout increases the residence time of the spunlace nonwoven fabric in the equipment, allowing it to fully absorb the heat from the drying cylinders 2 and the exhaust gas from the air outlet components, thereby enhancing the drying effect.

[0027] Furthermore, the hot air conveying device includes a hot air conveying pipe 6, which is connected to a heat source and also to the wire mesh drying cylinder 2 to provide hot air to the cylinder. The hot air conveying pipe 6 is used to convey the hot air generated by the heat source to the wire mesh drying cylinder 2 to meet the heat requirements of the drying process.

[0028] Furthermore, the exhaust duct 5 discharges the hot and humid gas through the negative pressure fan 7. In the dehumidification process, the exhaust duct 5 achieves dehumidification with the help of the negative pressure fan 7. The negative pressure fan 7 generates negative pressure to extract the hot and humid gas in the exhaust duct 5 and discharge it through the dehumidification pipe 4, thereby improving dehumidification efficiency and ensuring that the internal environment of the equipment is suitable for drying.

[0029] Furthermore, the drying cylinder 2 is driven by a drive motor to rotate, thereby driving the spunlace nonwoven fabric. The drying cylinder 2 is driven to rotate by the drive motor. When the drying cylinder 2 rotates, it drives the spunlace nonwoven fabric in contact with it, causing the spunlace nonwoven fabric to complete the drying process within the equipment along a predetermined route, achieving efficient drying of the spunlace nonwoven fabric roll.

The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
