Technical Field
[0001] This utility model relates to the field of nonwoven fabric processing technology, specifically to a nonwoven fabric bidirectional combing device. Background Technology
[0002] Non-woven fabric, also known as non-woven cloth, is a new generation of environmentally friendly material made from oriented or random fibers. It has the characteristics of being moisture-proof, breathable, flexible, lightweight, non-flammable, easily degradable, non-toxic and non-irritating, rich in colors, inexpensive, and recyclable.
[0003] Existing nonwoven fabric bidirectional ultra-uniform carding and web-laying devices on the market have significant limitations in the carding process, making it inconvenient for users to perform stepless adjustment and control based on the tension of different yarns.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0028] Based on existing technologies, the combing structure needs to be adjustable according to the tension of the yarn during the combing process, allowing for a certain stress margin adjustment. This prevents excessive pressure on the combing structure from damaging the yarn during the yarn tensioning and combing process. Please refer to [reference needed]. Figures 1-6 The embodiment provides a nonwoven fabric bidirectional carding device, which can effectively ensure that there is a certain stress margin in the carding structure during the carding process, and prevent the yarn from being damaged due to excessive pressure carding force. The nonwoven fabric bidirectional carding device includes a base 1, a winding device installed at the right end of the top surface of the base 1, an unwinding device installed at the left end of the top surface of the base 1, and a tensioning carding device installed in the middle of the top surface of the base 1.
[0029] The tensioning and carding device includes a tensioning structure and a carding structure. The carding structure is installed on both sides of the bottom center of the tensioning structure. The carding structure includes a hinge box 307, a rotating shaft 308 is installed in the center of the hinge box 307, a carding plate 309 is installed in the center of the outer surface of the rotating shaft 308, and a torsion spring 310 is fixedly connected to the center of the hinge box 307. The tensioning structure includes a carding frame 301, auxiliary roller frames 302 are arranged on the left and right sides of the carding frame 301, an electric push rod 303 is installed in the center of the top surface of the carding frame 301, a lifting plate 304 is installed at the output end of the electric push rod 303, a damping rod 305 is fixedly installed on the bottom surface of the lifting plate 304, and a tensioning roller 306 is fixedly connected to the bottom end of the damping rod 305.
[0030] The bottom end of the carding frame 301 is fixedly connected to the middle of the top surface of the base 1. The bottom end of the auxiliary roller frame 302 is fixedly connected to the top surface of the base 1. The hinge box 307 is fixedly installed on the middle of the left and right sides of the tension roller 306 near the top. The end of the torsion spring 310 away from the hinge box 307 is fixedly connected to the front and back of the carding plate 309 near the hinge box 307.
[0031] By setting up the tensioning combing device, the torsion spring 310 provides torque to the combing plate 309, thereby providing a certain stress margin during the combing process of the yarn, preventing the combing plate 309 from applying too much force to the yarn and causing damage to the yarn.
[0032] When tensioning and combing the yarn, the electric push rod 303 is activated to drive the lifting plate 304, damping rod 305, and tensioning roller 306 to descend. The tensioning roller 306, in cooperation with the two auxiliary roller frames 302, tensions the yarn. During the tensioning process, the damping rod 305 is deformed under pressure to prevent excessive tension from causing the yarn to break. At the same time, the combing plate 309 comes into contact with the yarn to comb it. During the combing process, the combing plate 309 rotates with the rotation shaft 308 and the hinge box 307 to change its angle. During the rotation and oscillation, a torque is applied to the torsion spring 310, causing the torsion spring 310 to deform. This provides a certain margin in the pressure applied by the combing plate 309, thus preventing the combing plate 309 from applying too much pressure to the yarn and causing damage to the yarn during the combing process. Example
[0033] Based on Implementation 1, the existing technology still has the problem of inconvenience in unwinding, rewinding, and changing the rolled yarn. Please refer to [reference needed]. Figures 1-3 This embodiment provides a bidirectional carding device for nonwoven fabrics, which can effectively replace the unwound and rewound yarns, thereby improving the efficiency of the carding process. The bidirectional carding device includes an unwinding device comprising an unwinding frame 201, an unwinding roller 202 mounted on the top of the unwinding frame 201, and a limiting rod 203 mounted on the top of the unwinding frame 201. A limiting pin 204 is connected to the left end of the left side of the top surface of the base 1. One end of the front and back of the unwinding roller 202 is rotatably connected to a groove in the middle of the top of the unwinding frame 201. The right end of the limiting rod 203 is hinged to the right end of the top of the unwinding frame 201. The limiting pin 204 is inserted into a limiting hole in the middle left side of the limiting rod 203 and the top left side of the unwinding frame 201.
[0034] The winding device includes a winding frame 101. An asynchronous motor 102 is mounted on the top front of the winding frame 101. The output end of the asynchronous motor 102 is connected to a connecting groove 103. Two connecting grooves 103 are connected to connectors 104 at their close ends. Two connecting heads 104 are fixedly connected to winding rollers 105 at their close ends. The bottom end of the winding frame 101 is fixedly connected to the right end of the top surface of the base 1. The connectors 104 and connecting grooves 103 are detachably connected by bolts. The middle of the two connecting grooves 103 is mounted inside mounting holes opened at the middle of the top ends of the two winding frames 101 via bearings.
[0035] By setting up the unwinding device and the winding device, the unwinding roller 202 is limited by the limiting rod 203, which facilitates the disassembly and replacement of the unwinding roller. The removable installation of the connecting groove 103 and the connecting head 104 by bolts facilitates the disassembly and replacement of the winding roller 105 after winding.
[0036] When unwinding and replacing the coiled yarn, the two ends of the unwinding roller 202 are placed inside the grooves at the top of the unwinding frame 201. Then, the unwinding roller 202 is limited by the hinge between the limiting rod 203 and the top of the unwinding frame 201, and the insertion limit pin 204 between the limiting rod 203 and the unwinding frame 201, thereby ensuring the stability of the unwinding roller 202 during the unwinding process, thus completing the quick disassembly and replacement of the unwinding roller 202. When replacing the wound yarn, the connecting groove 103 and the connector 104 are fixed by loosening the bolts, thereby disassembling and replacing the connector 104 and the take-up roller 105. When installing the new take-up roller 105, the connector 104 is engaged with the connecting groove 103 through a mounting groove. Then, the connecting groove 103 and the connector 104 are connected and fixed with bolts, thereby completing the replacement of the take-up roller 105. After that, the asynchronous motor 102 is started to drive the connecting groove 103 to rotate, thereby driving the take-up roller 105 to rotate and rewind.
