Technical Field

[0001] This utility model belongs to the field of nonwoven fabric processing technology, and in particular relates to a drying and curing device for superoleophilic and superhydrophobic nonwoven fabrics. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is a type of fabric formed without spinning and weaving. Depending on the different needs of its use, non-woven fabric can be coated to give it super-clear and super-hydrophobic properties. In the process of applying the coating to non-woven fabric, drying equipment is required to dry and cure the coating.

[0003] Some existing nonwoven fabric drying equipment simply has a heater to heat the nonwoven fabric. During the heating process, the heating temperature of the nonwoven fabric varies with the distance between it and the heater, resulting in uneven heating temperature in different parts of the nonwoven fabric, which affects the quality of the coating on the final nonwoven fabric.

[0004] Therefore, it is necessary to improve the existing drying and curing equipment. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a drying and curing device for superoleophilic and superhydrophobic nonwoven fabrics, thereby improving the uniformity of heating the nonwoven fabrics and enhancing the quality of the coating on the nonwoven fabrics.

[0014] Preferably, the heater includes a heating plate arranged parallel to the axial direction of the support roller, and multiple parallel heat dissipation fins are distributed on both sides of the heating plate, the heat dissipation fins being distributed along the axial direction of the support roller.

[0015] Preferably, the heat sinks are distributed in an S-shape along the axial direction of the support roller.

[0016] Preferably, the heating plate is detachably connected to the drying chamber.

[0017] Preferably, the upper and lower sides of the drying oven are provided with slots for inserting the heating plate, and the end of the heating plate is fixedly connected to a mounting plate, which covers the slots.

Detailed Implementation

[0027] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0028] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the drying and curing equipment and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.

[0029] like Figure 1 and 3 As shown, a drying and curing device for superoleophilic and superhydrophobic nonwoven fabrics includes:

[0030] Drying box 2, both ends of the drying box 2 are open and are respectively detachably connected to air inlet hood 8 and air outlet hood 4. The front and rear sides of the drying box 2 are respectively provided with inlet 201 and outlet 202 for non-woven fabric 1 to pass through in sequence.

[0031] Multiple support rollers 7 are arranged inside the drying chamber 2 and rotate around their own axis. The non-woven fabric 1 passes around each support roller 7 in sequence, so that the non-woven fabric 1 moves forward in a serpentine manner inside the drying chamber 2.

[0032] Multiple heaters 3 are arranged along the feed inlet 201 toward the discharge outlet 202. The nonwoven fabric 1 is staggered with each heater 3, so that the nonwoven fabric 1 passes between two adjacent heaters 3 in sequence.

[0033] The aforementioned drying and curing equipment can be used to cure the coating layer of the nonwoven fabric 1. During use, external air enters the drying chamber 2 through the air inlet hood and then exits through the exhaust hood 4. The nonwoven fabric 1 enters the drying chamber 2 through the inlet 201 and then exits through the outlet. The support rollers 7 are used to support the nonwoven fabric 1 and change its forward direction, causing it to move in a serpentine pattern, thereby extending its residence time inside the drying chamber 2 and increasing the heating area, thus improving the drying effect and efficiency. The heater 3 is equipped with multiple... The multiple heaters 3 are staggered with the nonwoven fabric 1, which increases the heating range of the nonwoven fabric 1 and improves the uniformity of heating, thus enhancing the drying effect of the nonwoven fabric 1. Furthermore, the multiple heaters 3 can be set to different temperatures, thereby forming different temperature zones inside the drying chamber 2 to improve the drying effect of the nonwoven fabric 1. The airflow direction inside the drying chamber 2 is parallel to the fabric surface of the nonwoven fabric 1, allowing the airflow to pass through both sides of the nonwoven fabric 1 simultaneously, achieving simultaneous drying of both sides of the nonwoven fabric 1 and ensuring uniform heating on both sides, further enhancing the drying effect of the nonwoven fabric 1.

[0034] Further improvements include, for example Figure 2 As shown, both ends of the drying chamber 2 are covered with perforated plates 5. Flange rings are provided at both ends of the drying chamber 2, the outer periphery of the perforated plates 5, the air inlet hood 8, and the exhaust hood 4. This allows for the assembly and disassembly of the components via bolt assemblies. The perforated plates 5 are installed between the air inlet hood 8 and the drying chamber 2, and between the exhaust hood 4 and the drying chamber 2. When the airflow passes through the perforated plates 5, the airflow encounters resistance and diffuses to the periphery of the perforated plates 5. Thus, the airflow enters the interior of the drying chamber 2 through the holes on the perforated plates 5 and is evenly dispersed, thereby allowing the airflow to blow evenly over all parts of the nonwoven fabric 1, improving the uniformity of drying the nonwoven fabric 1 and enhancing the processing quality of the nonwoven fabric 1.

[0035] Further improvements include, for example Figure 2 As shown, the end of the drying chamber 2 connected to the air inlet hood 8 is covered with a filter screen 6. A flange ring is provided on the outer periphery of the filter screen 6. The filter screen 6 is used to filter dust and impurities in the air entering the air inlet hood 8, improve the cleanliness of the airflow entering the drying chamber 2, reduce the chance of the nonwoven fabric 1 being contaminated, and improve the quality of the nonwoven fabric 1 produced.

[0036] Further improvements include, for example Figure 4 and 5 As shown, the support roller 7 has a roller shaft 701, which is connected to the drying chamber 2 via bearings. The support roller 7 is a hollow tubular structure, and multiple through holes 702 are evenly distributed on its outer circumferential surface. When the airflow flows along the axial direction of the support roller 7, it can pass through the interior of the support roller 7 and contact the nonwoven fabric 1 through the through holes 702, thereby making the nonwoven fabric 1 dry evenly and improving the drying effect on the nonwoven fabric 1.

[0037] Further improvements include, for example Figure 6 As shown, the heater 3 includes a heating plate 301 arranged axially parallel to the support roller 7. Multiple parallel heat sinks 302 are distributed on both sides of the heating plate 301, and the heat sinks 302 are distributed along the axial direction of the support roller 7. The heating plate 301 and the heat sinks 302 are integrally formed and made of aluminum alloy. The heating plate 301 is positioned directly opposite the surface of the nonwoven fabric 1, thus increasing the heating range of the heater 3 and the nonwoven fabric 1, improving the drying speed and uniformity of the nonwoven fabric 1. The heat sinks 302 increase the heat diffusion range, further improving the heating uniformity of the nonwoven fabric 1 and enhancing the drying effect.

[0038] Further improvements include, for example Figure 6 As shown, the heat sinks 302 are distributed in an S-shape along the axial direction of the support roller 7. The heat sinks 302 distributed along the axial direction of the support roller 7 allow airflow to pass through the gaps between the heat sinks 302, thereby making the heat evenly distributed inside the drying chamber 2, improving the heating uniformity of the nonwoven fabric 1, and improving the drying effect of the nonwoven fabric 1.

[0039] Further improvements include, for example Figure 4 and 6 As shown, the heating plate 301 is detachably connected to the drying chamber 2. This detachable connection facilitates the replacement and maintenance of the heating plate 301, improving the ease of use of the drying and curing equipment.

[0040] Further improvements include, for example Figure 4 and 6 As shown, slots 203 for inserting heating plates 301 are provided on both the upper and lower sides of the drying chamber 2. A mounting plate 303 is fixedly connected to the end of the heating plate 301, and the mounting plate 303 covers the slots 203. The mounting plate 303 is fixedly connected to the drying chamber 2 by bolts, thereby enabling the heater 3 to be installed and removed. The heater 3 is inserted into the drying chamber 2 through the slots 203, allowing it to be removed from the outside of the drying chamber 2, thus improving the ease of use of the drying and curing equipment.

[0041] Further improvements include, for example Figure 6 As shown, the end of the mounting plate 303 has multiple blind holes 304 for inserting heating rods 305, and the blind holes 304 are arranged at equal intervals along the axial direction of the support roller 7. Each blind hole 304 is equipped with a heating rod 305, which allows for easy replacement and maintenance of the heating rod 305 from outside the drying chamber 2, improving the ease of use of the drying and curing equipment; at the same time, the equal intervals of the blind holes 304 ensure that the heating rods 305 are evenly distributed inside the heating plate 301, thereby improving the uniformity of heating of the heating plate 301, improving the uniformity of heating of the nonwoven fabric 1, and improving the drying effect of the nonwoven fabric 1.
