Description

Technical Field

[0001] This utility model relates to a shearing device, and more particularly to a shearing device for producing nano-yarn, belonging to the field of yarn production technology. Background Technology

[0002] As an important branch of nanomaterials science, nanoyarns have shown broad application prospects in fields such as high-efficiency filtration, intelligent sensing, biomedicine, and aerospace, thanks to their ultra-large specific surface area, excellent mechanical properties, and unique surface functionalization characteristics.

[0003] Because the pressurized chamber is filled with pressurized nanomaterials, when the yarn passes through the pressurized chamber, its surface is coated with a nanofilm. After being dried in the drying channel and then wound up, nanoscale yarn is obtained. The nano yarn is then wound into a nano yarn roll.

[0004] Conventional yarn cutting equipment uses mechanical blades for cutting, and traditional cutting methods are prone to fiber breakage, increased fuzz, and structural damage. In addition, nano yarns are sensitive to temperature, and high temperatures may cause the material to soften or degrade. When using a single blade for cutting, the yarn ends break apart due to elastic recovery, with a yarn end dispersion rate of over 30%, which seriously affects product quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a shearing device for nanofiber production that can reduce the damage caused by extrusion of nanowires and prevent the material from softening or degrading.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A shearing device for producing nano-yarn includes a transport plate and a gantry support frame fixedly mounted on the transport plate. A plurality of nano-wires are arranged on the upper side of the transport plate. A horizontal drive mechanism is slidably mounted on the gantry support frame, and a cutting mechanism is slidably mounted on the horizontal drive mechanism. The cutting mechanism includes a blade handle and a blade head that are engaged and connected. One end of the blade head is provided with a V-shaped cutting nozzle, which corresponds to the nano-wires.

[0008] The transport plate has several water-cooling holes inside, and a water-cooling mechanism is connected to each water-cooling hole. The water-cooling mechanism includes a water pump and a water tank connected by a connecting pipe. The water pump is connected to one end of the water-cooling hole through a water inlet pipe, and the other end of the water-cooling hole is connected to the inside of the water tank through a drain pipe.

[0009] Furthermore, the upper side of the transport plate is provided with a plurality of transport grooves, the nanowires are disposed inside the transport grooves, and a positioning drive mechanism is fixedly disposed inside the transport grooves. The positioning drive mechanism includes a positioning guide head and a drive component. The drive component includes symmetrically distributed drive rollers, the nanowires are disposed between the drive rollers, and the drive rollers are fixedly disposed inside the transport grooves by a drive roller support frame.

[0010] Furthermore, a horizontal drive motor is fixedly installed on the horizontal drive mechanism, a horizontal drive gear is provided at the output end of the horizontal drive motor, a drive tooth groove is provided on the upper side of the gantry support frame, and the horizontal drive gear is meshed with the drive tooth groove.

[0011] Furthermore, the horizontal drive mechanism is connected to symmetrically distributed limit wheel support rods, and limit rollers are rotatably mounted on the limit wheel support rods, with the limit rollers abutting against the lower side of the gantry support frame.

[0012] Furthermore, the gantry support frame is provided with a cutting groove, and the cutting mechanism is slidably disposed inside the cutting groove.

[0013] Furthermore, a guide limiting plate is fixedly installed on the horizontal drive motor, and a limiting guide strip is fixedly installed inside the guide limiting plate. A guide groove is opened on one side of the cutting mechanism, and the guide groove is slidably connected to the limiting guide strip.

[0014] Furthermore, a vertical drive motor is fixedly mounted on one side of the guide limiting plate on the horizontal drive mechanism, and a vertical drive gear is mounted on the output end of the vertical drive motor. A tool holder drive tooth that meshes with the vertical drive gear is mounted on one side of the cutting mechanism.

[0015] Furthermore, the bottom of the transport plate is provided with several support columns, and the water cooling mechanism is located at the bottom of the transport plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Compared to traditional flat-blade cutters, the V-shaped cutting nozzle can reduce the compression of nanowires, thereby reducing damage to the nanofilm on the surface of the nanowires. The water pump draws liquid from inside the water tank and then passes it through the water cooling hole. As the liquid passes through the water cooling hole, it carries away the heat from the transport plate, achieving the purpose of heat dissipation for the transport plate, avoiding material softening or degradation, ensuring the quality of nanowires, and improving the precision of shearing.

[0018] 2. The nanowires are cut step by step to prevent continuous cutting damage. The horizontal drive gear meshes with the drive tooth groove to achieve the purpose of horizontal movement of the horizontal drive mechanism. A cutting groove is opened on the gantry support frame. While the horizontal drive mechanism moves, it drives the cutting mechanism to slide inside the cutting groove. A tool holder drive tooth is fixedly set on one side of the cutting mechanism. After the vertical drive motor is started, the vertical drive gear rotates to drive the cutting mechanism to slide vertically, thereby cutting the nanowires. Attached Figure Description

[0029] The technical solution of this utility model will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1-9 As shown, the shearing device for producing nano-yarns provided in this embodiment includes a transport plate 1 and a gantry support frame 2 fixedly mounted on the transport plate 1. A plurality of nano-yarns 7 are arranged on the upper side of the transport plate 1. A horizontal drive mechanism 3 is horizontally slidably mounted on the gantry support frame 2, and a cutting mechanism 6 is vertically slidably mounted on the horizontal drive mechanism 3. The cutting mechanism 6 includes a blade handle 601 and a blade head 602 that are engaged and connected. One end of the blade head 602 is provided with a V-shaped cutting nozzle 603, which corresponds to the nano-yarns 7. The plurality of nano-yarns 7... All components are mounted on the upper side of the transport plate 1. The horizontal drive mechanism 3 can cut multiple nanowires 7 simultaneously, improving the range and flexibility of use. The cutting mechanism 6 is slidably positioned directly above the nanowires 7. As the cutting mechanism 6 moves downward, the V-shaped cutting nozzle 603 on the cutter head 602 cuts the nanowires 7. When the yarn passes through the nanomaterial coating and pressure chamber, its surface is coated with a nanofilm. After drying in the drying channel and then being wound up, nanoscale yarn is obtained. The traditional method is to cut the nanowires 7 with a flat-bladed cutter. However, the flat-bladed cutter will squeeze the nanowires 7 during the cutting process. Compared with the traditional flat-bladed cutter, the V-shaped cutting nozzle 603 can reduce the squeezing of the nanowires 7, thereby reducing the damage to the nanofilm on the surface of the nanowires 7 and improving the cutting accuracy.

[0031] Nano-yarns are temperature-sensitive; high temperatures may cause the material to soften or degrade. Therefore, they need to be cut at room temperature or lower. Thus, the cutting temperature must be controlled during the cutting process. The transport plate 1 has several water-cooling holes 101 inside, each connected to a water-cooling mechanism 4. The water-cooling mechanism 4 includes a water pump 401 and a water tank 402 connected by a connecting pipe 405. The water pump 401 is connected to one end of the water-cooling hole 101 via an inlet pipe 403, and the other end of the water-cooling hole 101 is connected to a drain pipe. Pipe 404 is connected to the interior of water tank 402. Water pump 401 is connected to one end of water cooling hole 101 through water inlet pipe 403. Water tank 402 is connected to the other end of water cooling hole 101 through drain pipe 404. Water pump 401 draws liquid from inside water tank 402 and then passes it through water cooling hole 101. When the liquid passes through water cooling hole 101, it carries away the heat on transport plate 1, thereby achieving the purpose of heat dissipation of transport plate 1, avoiding material softening or degradation, ensuring the quality of nanowire 7, and improving the precision of shearing.

[0032] Furthermore, in order to ensure the stability of transportation, such as Figure 1 and Figure 8 As shown, the upper side of the transport plate 1 has several transport grooves 102. The nanowires 7 are disposed inside the transport grooves 102. A positioning drive mechanism 5 is fixedly disposed inside the transport grooves 102. The positioning drive mechanism 5 includes a positioning guide head 501 and a drive component 502. The nanowires 7 are guided and supported by multiple drive components 502, thereby improving the stability of the nanowires 7. The drive component 502 includes symmetrically distributed drive rollers 504. The nanowires 7 are disposed between the drive rollers 504. The drive rollers 504 are fixedly disposed inside the transport grooves 102 by drive roller support frame 503. At the same time, the positioning drive mechanism 5 is also provided with drive rollers 504. After the drive rollers 504 are started, they can drive the nanowires 7 and improve the stability of the transport of the nanowires 7.

[0033] Furthermore, when cutting the nanowire 7, such as Figures 4-6 As shown, a horizontal drive motor 301 is fixedly mounted on the horizontal drive mechanism 3. A horizontal drive gear 302 is mounted on the output end of the horizontal drive motor 301. A drive tooth groove 202 is mounted on the upper side of the gantry support frame 2. The horizontal drive gear 302 meshes with the drive tooth groove 202. To prevent continuous cutting damage, the nanowires 7 need to be cut step by step. When cutting the nanowires 7 step by step, the horizontal drive mechanism 3 on the gantry support frame 2 needs to be moved first. The specific process of moving the horizontal drive mechanism 3 is as follows:

[0034] Start the horizontal drive motor 301 on the horizontal drive mechanism 3. The horizontal drive motor 301 drives the horizontal drive gear 302 to rotate. The horizontal drive gear 302 meshes with the drive tooth groove 202. Therefore, while the horizontal drive gear 302 is rotating, the horizontal drive mechanism 3 can move horizontally on the gantry support frame 2, so as to achieve the purpose of horizontal movement of the horizontal drive mechanism 3.

[0035] To ensure the stability of the horizontal drive mechanism 3's movement, such as Figure 4 As shown, the horizontal drive mechanism 3 is connected to symmetrically distributed limit wheel support rods 305. Limit rollers 306 are rotatably mounted on the limit wheel support rods 305. The limit rollers 306 abut against the lower side of the gantry support frame 2. The limit rollers 306 are connected to the bottom of the horizontal drive mechanism 3 through the limit wheel support rods 305. The limit rollers 306 abut against the bottom of the gantry support frame 2, which can ensure the stability of the operation of the horizontal drive mechanism 3. The gantry support frame 2 is provided with a cutting groove 201. The cutting mechanism 6 is slidably disposed inside the cutting groove 201. The horizontal drive mechanism 3 must ensure the movement of the cutting mechanism 6 while it is moving. Therefore, the cutting groove 201 is provided on the gantry support frame 2. While the horizontal drive mechanism 3 is moving, it drives the cutting mechanism 6 to slide inside the cutting groove 201.

[0036] The horizontal drive mechanism 3 performs horizontal movement, while the cutting mechanism 6 slides vertically. Figure 1 As shown, a vertical drive motor 303 is fixedly mounted on one side of the guide limiting plate 307 on the horizontal drive mechanism 3. A vertical drive gear 304 is mounted on the output end of the vertical drive motor 303. A tool holder drive gear 604 that meshes with the vertical drive gear 304 is mounted on one side of the cutting mechanism 6. A tool holder drive gear 604 is fixedly mounted on one side of the cutting mechanism 6. After the vertical drive motor 303 is started, the vertical drive gear 304 rotates to drive the cutting mechanism 6 to slide vertically, thereby cutting the nanowires 7. A guide limiting plate 307 is fixedly mounted on the horizontal drive motor 301. A limiting guide strip 308 is fixedly mounted inside the guide limiting plate 307. A guide groove 605 is opened on one side of the cutting mechanism 6. The guide groove 605 is slidably connected to the limiting guide strip 308. In order to ensure the stability of the movement of the cutting mechanism 6, the limiting guide strip 308 on the guide limiting plate 307 can be slidably mounted inside the guide groove 605, thereby ensuring the stability of the sliding of the cutting mechanism 6.

[0037] In addition, to facilitate the replacement of the cutter head 602 later, the cutter head 602 is snapped into the cutter holder 601, which facilitates the replacement of the cutter head 602 later and improves the flexibility and practicality of the device.

[0038] The bottom of the transport plate 1 is provided with several support columns 8, and the water cooling mechanism 4 is located at the bottom of the transport plate 1. The support columns 8 support the transport plate 1, thereby improving the stability of the transport plate 1. At the same time, the water cooling mechanism 4 is located at the bottom of the transport plate 1, thereby improving the space utilization rate.

[0039] like Figures 1-9 As shown, the principle of the shearing device for producing nano-yarns provided in this embodiment is as follows:

[0040] Multiple nanowires 7 are arranged on the upper side of the transport plate 1. The horizontal drive mechanism 3 can cut multiple nanowires 7 simultaneously, improving the range of use and flexibility. The cutting mechanism 6 is slidably arranged directly above the nanowires 7. As the cutting mechanism 6 moves downward, the V-shaped cutting nozzle 603 on the cutter head 602 cuts the nanowires 7. When the yarn passes through the nanomaterial coating and pressure chamber, its surface is coated with a nanofilm. After drying in the drying channel and being wound up, nanoscale yarn is obtained. The traditional method is to cut the nanowires 7 with a flat blade. However, the flat blade will squeeze the nanowires 7 during the cutting process. Compared with the traditional flat blade, the V-shaped cutting nozzle 603 can reduce the squeezing of the nanowires 7, thereby reducing the damage to the nanofilm on the surface of the nanowires 7 and improving the cutting accuracy.

[0041] Nanofiber yarns are temperature sensitive; high temperatures may cause the material to soften or degrade. Therefore, they need to be cut at room temperature or lower. Thus, the cutting temperature needs to be controlled during the cutting process. Water pump 401 is connected to one end of water cooling hole 101 through water inlet pipe 403, and water tank 402 is connected to the other end of water cooling hole 101 through drain pipe 404. Water pump 401 draws liquid from inside water tank 402 and then passes it through water cooling hole 101. As the liquid passes through water cooling hole 101, it carries away the heat from transport plate 1, achieving the purpose of heat dissipation for transport plate 1, avoiding material softening or degradation, ensuring the quality of nanofiber 7, and improving the cutting precision.
