[0029] Figure 1 It is a top view of an embodiment of the utility model, referring to Figure 1 One embodiment of the utility model provides a protective clothing material preparation device based on spunlace non-woven materials, which is used to prepare suitable non-woven materials according to the requirements of protective clothing.

[0030] Furthermore, the preparation device of the utility model includes a combing device 100 and a spunlace device 200 from front to back. The combing device 100 combs the polyester fibers and spreads them directly on the mesh curtain to form a simple fiber web. The spunlace device 200 then sprays a high-pressure water jet to puncture the fiber web to reinforce the fiber web.

[0031] Further, refer to Figure 2 The combing device 100 includes a combing conveyor belt group 110 for conveying polyester fibers. A combing device tensioning roller 120 is provided on the combing conveyor belt group 110. Combing brush devices 130 are provided on both sides of the combing device tensioning roller 120. The combing device tensioning roller 120 is used to support the conveyor belt so that the polyester fibers on the conveyor belt can better fit the combing brush device 130, thereby improving the combing effect.

[0032] Further, refer to Figure 2 , Figure 3 A combing and blowing device 140 is provided next to the combing brush device 130. When the combing brush device 130 combs the polyester fibers, the combing and blowing device 140 blows air to the polyester fibers. The combing and blowing device 140 includes a fan 141 and an air outlet 142. The air outlet 142 is provided with an air distribution plate 143, and air distribution holes 144 are distributed on the air distribution plate 143. The fan 141 drives the air outlet 142 to discharge air. After the air flow passes through the air distribution holes 144 of the air distribution plate 143, a plurality of air flows with high air pressure but small blowing areas are formed, so that the polyester fibers after combing are more orderly distributed.

[0033] In actual operation, when the combing conveyor belt group 110 sends the polyester fibers to the position of the combing brush device 130, the combing brush device 130 combs the polyester fibers, and cooperates with the multiple fine and strong needle-like airflows blown by the combing blowing device 140 to make the polyester fibers combed by the combing brush device 130 arranged more neatly, which is more conducive to the antistatic agent adsorption effect of the polyester fibers. In addition, the airflow blown by the combing blowing device 140 can also blow away the fine dust on the polyester fibers without blowing the polyester fibers apart.

[0034] In some embodiments, a dust collecting cylinder is provided next to the combing and blowing device 140 to comb the dust blown up by the combing and blowing device 140 .

[0035] In some embodiments, an air outlet heater 145 is disposed in the air outlet cylinder 142 so that the air flow blown out by the combing and blowing device 140 is hot air, thereby improving the combing effect on the polyester fibers.

[0036] Some embodiments, see Figure 4 The combing brush device 130 includes a rotating frame 131, on which a combing brush head 133 is arranged. The rotating frame 131 rotates to drive the combing brush head 133 to perform continuous beating and combing actions. The combing brush head 133 has a convex arc surface 134, on which bristles are arranged, so that the combing brush head 133 can better fit the polyester fiber and improve the combing effect.

[0037] In some embodiments, the combing brush device 130 includes an arc-shaped cleaning plate 135, and the arc-shaped cleaning plate 135 is provided with hooked bristles 136. In this way, the combing brush head 133 will pass through the arc-shaped cleaning plate 135 when it moves, and the hooked bristles 136 on the arc-shaped cleaning plate 135 clean the impurities entangled in the bristles of the combing brush head 133.

[0038] In some embodiments, an elastic connector 132 is disposed on the rotating frame 131 , the combing brush head 133 is connected to the elastic connector 132 , and a spring is disposed between the combing brush head 133 and the elastic connector 132 .

[0039] In some embodiments, a bamboo curtain conveying frame 150 is provided between the combing device 100 and the spunlace device 200, and the preliminarily formed fiber web after combing is conveyed on the bamboo curtain conveying frame 150. The bamboo curtain conveying frame 150 is both halo and breathable, and is more suitable for conveying the fiber web than a conveyor belt.

[0040] Some embodiments, see Figure 5 The spunlacing device 200 includes a spunlacing conveying roller group 210, and a spunlacing chamber 220 is arranged between the spunlacing conveying roller group 210. The spunlacing conveying roller group 210 is responsible for conveying the fiber web into the spunlacing chamber 220. A spunlacing squeezing roller group 221 is arranged in the spunlacing chamber 220, which is responsible for pulling and pressing the fiber web. A spunlacing plate 222 is arranged between the spunlacing squeezing roller groups 221, and spunlacing water nozzles 223 are distributed on the spunlacing plate 222. The spunlacing water nozzles 223 eject high-pressure water jets to puncture the fiber web to complete the spunlacing process.

[0041] In this embodiment, optionally, the water pressure of the high-pressure water jet emitted by the spurting water nozzle 223 is 5.0×106~1.0×107Pa.

The water receiving tank 240 is connected to a water collecting box 250 through a drainage pipe to collect the accumulated water on the water receiving tank 240 for centralized drainage.

[0044] In some embodiments, the spunlace device 200 includes a primary drying chamber 230, and a drying heating roller 231 is disposed in the primary drying chamber 230. The drying heating roller 231 is heated to squeeze out excess water from the fiber web and dry the residual water, thereby performing a preliminary drying process on the fiber web.

[0045] In some embodiments, a ventilation fan is provided in the primary drying chamber 230 to remove moisture in the primary drying chamber 230 to prevent the fiber web from getting damp.

[0046] In some embodiments, a hot air blower 232 is disposed in the primary drying chamber 230, and the hot air blower 232 blows out hot air to accelerate the drying of the fiber web.

[0047] Some embodiments, see Figure 1 The preparation device of the utility model also includes a fluffing device 300 for performing a fluffing process on the fiber raw material.

[0048] In some embodiments, the preparation device of the utility model further includes a cotton feeding device 400 for transporting the fibers to the combing device 100 after they are finished.

[0049] In this embodiment, optionally, a predetermined mass of end-epoxy polyether, a predetermined mass of viscose fiber, and a predetermined mass of cross-linking agent are added to a predetermined mass of desalted water or deionized water, and after adjustment with alkali and stirring, the mixture is dehydrated and dried and then fed into the cotton feeding device 400.

[0050] In some embodiments, the preparation device of the utility model further includes a drying device 500, and the fiber web is dried at high temperature in the drying device 500 to form a non-woven fabric sheet.

[0051] In some embodiments, the preparation device of the utility model further includes a slitting device 600 for slitting the non-woven fabric sheets.

[0052] In some embodiments, when the preparation device of the utility model is working, the fiber raw material is first preliminarily opened manually in the opening area. Then, the fluffing device 300 is used for rough opening and fine opening, and the fiber raw materials are mixed to open the large fiber blocks into loose fibers. Then, it is transported to the cotton feeding device 400, and the fibers with a certain required proportion are transported to the combing device 100 for combing, and then collected on the laying curtain. The production line is straight laying, and a simple fiber web is formed by straight laying. Then, it passes through the water spunlace device 200, and the fiber web is reinforced by piercing the fiber web with a high-pressure water jet, and then it is dried at 120°C for 30s through the drying device 500 to form a non-woven fabric sheet. Then, the non-woven fabric sheet undergoes a series of electronic tests such as defects, metal, gram weight, moisture, etc., and finally rolled, cut on the slitting device 600, and finally packaged, and the non-woven fabric is thus prepared.
