Referring to fig. 1, the present application provides an apparatus for twisting micro-nanofiber material, comprising: the device comprises a working device 10, a collecting device 20, an air supply device 30, a bracket 40 and a box body 50 provided with holes, wherein the air supply device 30 is connected with the working device 10, and the air supply device 30 is arranged at the holes of the box body 50 and is used for providing vertical air flow; the working device 10 is arranged above the air supply device 30 and is used for twisting micro-nano fiber materials; the bracket 40 is mounted to the edge of the case 50; and the collecting device 20 is mounted on the bracket 40, and the mounting position of the collecting device 20 corresponds to the working device 10 and is used for collecting micro-nanofiber yarns generated by twisting micro-nanofiber materials by the working device 10.
As described in the background art, the yarn is a product with certain fineness which is processed by micro-nano fiber materials, and can be widely used in textile fields such as weaving, rope making, thread making, knitting, embroidery and the like. Conventional yarns are all made from macroscopic, micro-sized fibrous materials by twisting. Therefore, the micro-nano fiber material is twisted into yarn, and is widely applied to the textile subdivision fields of weaving, rope making, thread making, knitting, embroidery and the like, and is a technology with great potential. However, since the fiber diameter of the micro-nanofiber material is extremely small, it is hardly visible to the naked eye, and the single micro-nanofiber material cannot be twisted or extracted by conventional technical means. Therefore, it is a difficult problem how to integrate and twist a single micro-nanofiber material into one micro-nanofiber bundle in order, thereby forming a micro-nanofiber yarn.
Aiming at the technical problems, the application provides equipment for twisting micro-nano fiber materials. It is mainly composed of a working device 10, a collecting device 20, an air supply device 30, a bracket 40 and a box 50. Wherein the housing 50 is provided with a plurality of holes. The air supply device 30 is connected with the working device 10, wherein the air supply device 30 is arranged at a hole of the box body 50, the working device 10 is arranged above the air supply device 30, the bracket 40 is arranged at the edge of the box body 50, the collecting device 20 is arranged on the bracket 40, and the installation position of the collecting device 20 corresponds to the installation position of the working device 10.
Referring to fig. 1, a plurality of holes are provided in the case 50, and a plurality of air supply devices 30 are provided at positions corresponding to the holes. Above the plurality of air supply devices 30, corresponding working devices 10 are provided. The interior of each working device 10 stores a liquid that is spinnable. The working device 10 can spray out spinnable liquid by virtue of centrifugal force generated by self rotation, and can prepare micro-nanofiber materials in air. And because the velocity of the vertical air flow provided by the air supply device 30 is very high, the force provided by the vertical air flow to which the micro-nanofiber material is subjected is much greater than the centrifugal force in the horizontal direction provided by the working device 10, so that the micro-nanofiber material can form ordered micro-nanofiber bundles in the vertical direction. And because the micro-nanofiber material is subjected to the vertical force provided by the vertical air flow and the centrifugal force in the horizontal direction provided by the working device 10, the micro-nanofiber bundles can be twisted in the air to finally form micro-nanofiber yarns, and the twisted micro-nanofiber yarns are collected by a plurality of corresponding collecting devices 20.
Further, since the case 50 is provided with a plurality of holes and the air supply devices 30 are provided at the holes, and the working devices 10 are provided at the positions corresponding to the air supply devices 30, a large amount of micro-nanofiber yarns can be produced. And because a plurality of collecting devices 20 are arranged corresponding to a plurality of working devices 10, the collecting devices 20 can collect the micro-nano fiber yarns in time, so that the micro-nano fiber yarns can not adhere in the air.
In summary, since the air supply device 30 is provided in the present application, the working device 10 is provided at the position corresponding to the upper side of the air supply device 30, and the air supply device 30 can provide vertical air flow. The operation device 10 can spray the spinnability liquid by virtue of centrifugal force generated by rotation of the operation device, and can form micro-nano fiber materials in air, wherein the micro-nano fiber materials can form ordered micro-nano fiber bundles under the action of vertical force provided by vertical air flow. The micro-nanofiber bundles can be twisted to form micro-nanofiber yarns under the action of centrifugal force in the horizontal direction and vertical force provided by vertical air flow. Therefore, the technical effects that the micro-nano fiber material can be efficiently and orderly integrated into micro-nano fiber bundles through the product structure, and the micro-nano fiber bundles are twisted to form the micro-nano fiber yarn are achieved. And further solves the technical problem that the prior art lacks equipment for efficiently and orderly integrating micro-nano fiber materials into micro-nano fiber bundles and twisting the micro-nano fiber bundles to form micro-nano fiber yarns.
Further, reference is made to fig. 2A and 2B. As can be seen from fig. 2A, the micro-nanofiber yarn was about 300 μm. In fig. 2B, the micro-nanofiber yarn obtained by twisting is shown at the upper part, and the micro-nanofiber bundle to be twisted is shown at the lower part. As can be seen from fig. 2B, the micro-nanofiber bundles can form micro-nanofiber yarns under the effect of vertical air flow.
Referring to fig. 2C, the single micro-nanofiber yarn is secondarily drawn during twisting, becoming finer. The surface of the micro-nano fiber yarn is rougher, which is beneficial to increasing the friction force of the micro-nano fiber yarn.
Alternatively, the air supply 30 provides a vertical air flow rate in the range of 4.5 to 20m/s.
Specifically, the air supply device 30 provides a vertical air flow with a velocity ranging from 4.5 to 20m/s, and the vertical air flow within this range has a velocity that enables the micro-nanofiber material ejected by the working device 10 to form an ordered micro-nanofiber bundle in the air.
Optionally, the working device 10 includes: a driving device 110, a spinning device 120 and an air hood 130, wherein the driving device 110 is connected with the spinning device 120 for providing driving force; the air cap 130 is disposed outside the spinning device 120 for changing the flow direction of the air stream; and a spinning device 120 for preparing the micro-nanofiber material.
Specifically, referring to fig. 3, the working device 10 is composed of a driving device 110, a spinning device 120, and an air cap 130. The air cap 130 is disposed outside the spinning device 120, and the driving device 110 is connected to the spinning device 120.
The driving device 110 can drive the spinning device 120 to rotate, and the spinning device 120 generates centrifugal force in the rotating process, and the spinnability liquid stored in the spinning device 120 can be sprayed out by virtue of the centrifugal force, so that the micro-nanofiber material is prepared in the air. Since the spinning device 120 generates a horizontal air flow during the rotation process, the air cap 130 can change the flow direction of the air flow in the horizontal direction and the vertical direction in order to change the direction of the micro-nano fiber material prepared in the air. Thus, the air flow changing the direction of flow via the air cap 130 and the vertical air flow provided by the air supply device 30 can form a combined air flow, and the air flow provides a greater force to the micro-nanofiber material. Thus, the micro-nanofiber material prepared by the spinning device 120 can orderly form micro-nanofiber bundles under the action of the force provided by the air-mixing flow.
Therefore, the technical effect of orderly integrating the micro-nano fiber materials into the micro-nano fiber bundles is achieved through the product structure.
Optionally, the spinning device 120 includes: a spinning part 121 and a feeding part 122, wherein the feeding part 122 is disposed below the spinning part 121 without contact; and the spinning member 121 is connected to the driving device 110.
Specifically, referring to fig. 4, the spinning device 120 is composed of a spinning member 121 and a feeding member 122. The feeding part 122 is disposed below the spinning part 121 in a non-contact manner, and can add spinnability liquid into the spinning part 121, and the spinning device 121 can spray the spinnability liquid stored in the spinning part by using centrifugal force generated by rotation of the spinning device, so that the filament-shaped micro-nano fiber material is finally prepared.
Therefore, the technical effect of being capable of generating continuous filiform micro-nano fiber materials is achieved through the product structure.
Optionally, the spinning part 121 includes: a canister 1211, wherein the canister 1211 is coupled to the drive 110 for storing the spinnability liquid.
Specifically, referring to fig. 4, the spinning device 121 includes a can 1211, and the can 1211 is connected to the driving device 110. The canister 1211 is used primarily to store a spinnability liquid, among other things.
Therefore, the product structure achieves the technical effects of storing spinnability liquid and providing necessary conditions for preparing the micro-nano fiber material.
Optionally, the spinning part 121 includes: needle 1212, needle mount tube 1213, needle clasp cap 1214, and needle clasp clip 1215, wherein needle 1212 is removably mounted to needle mount tube 1213; a needle clasp 1214 is wrapped around the needle 1212 and the needle mount tube 1213; and a needle fastening clip 1215 is provided on the outside of the canister 1211.
Specifically, referring to fig. 5 and 6, the spinning member 121 mainly includes a needle 1212, a needle mounting tube 1213, a needle fastening cover 1214, and a needle fastening clamp 1215. A plurality of needle mounting tubes 1213 are detachably mounted to the outer circumference of the can 1211, and a needle 1212 is detachably mounted to each of the needle mounting tubes 1213. Needle clasp 1214 wraps around needle 1212 and needle mount 1213 to protect needle 1212 and needle mount 1213. Wherein needle clasp cap 1214 is capable of tightly clasping needle 1212 and needle mount tube 1213, preventing needle 1212 and needle mount tube 1213 from loosening or falling out under the influence of a large centrifugal force. Needle clasp 1214, needle 1212, and needle mount tube 1213 are coaxial. And wherein, in order to ensure that the coaxial relationship of needle clasp 1214, needle 1212 and needle mounting tube 1213 does not deviate, the inside diameter tube diameter of needle clasp 1214 is the same as the outside diameter tube diameter of needle mounting tube 1213, so that needle clasp 1214 and needle mounting tube 1213 are able to fully conform. The needle fastening clip 1215 is provided outside the can 1211, and the needle fastening clip 1215 can tightly clamp the needle fastening cover 1214, preventing the needle fastening cover 1214, the needle 1212 and the needle mounting tube 1213 from falling off the can 1211 by centrifugal force, avoiding potential safety hazards.
Further, since the needle fastening clip 1215 wraps the can 1211, the needle mounting tube 1213, and a portion of the needle 1212, exposing only the tip of the needle 1212 outside the needle fastening clip 1215, no falling off of the needle 1212 and the needle mounting tube 1213 occurs during the rotation of the spinning member 121 itself.
During rotation of the spinning member 121 by the driving means 110, the spinnable liquid stored in the tank 1211 can flow to the needle 1212 through the needle mount tube 1213 by centrifugal force and be sprayed to the outside of the needle fastening jig 1215 through the needle 1212. In a dry environment, the spinnability liquid sprayed outside the needle fastening clamp 1215 gradually becomes a filiform micro-nanofiber material.
In addition, since needle 1212, needle mount tube 1213 and canister 1211 are configured in a three-phase, separate configuration, needle 1212 and needle mount tube 1213 are readily removable from canister 1211, and needle 1212 is readily removable from needle mount tube 1213. Thereby, the technical effect of facilitating cleaning of the needle mounting tube 1213 and the can 1211 and ensuring multiple uses of the needle mounting tube 1213 and the can 1211 is achieved.
Thus, the technical effect of ensuring that the needle 1212 and the needle mounting tube 1213 do not fall off and further ensuring that the spinning member 121 can operate normally is achieved by the above-described product structure.
Alternatively, the inner ring of the can 1211 has a polygonal shape, and the mounting position of the needle mounting tube 1213 corresponds to the position of the vertex of the inner ring of the can 1211.
Specifically, referring to fig. 7, the can 1211 is divided into an inner ring and an outer ring, and the inner ring of the can 1211 in the spinning member 121 in the related art is circular. A needle mounting tube 1213 is mounted on the outer race of the canister 1211 and a needle 1212 is mounted on the needle mounting tube 1213. Since the inner ring of the can 1211 is circular, the flow direction of the spinnability liquid stored in the can 1211 is normal, not toward the needle mounting tube 1213. Thus, during the flow of the spinnability liquid in the tank 1211, a phenomenon in which the spinnability liquid is deposited on the inner wall of the tank 1211 and forms gel may occur.
Specifically, referring to fig. 5, the can 1211 is divided into an inner ring and an outer ring, and the shape of the inner ring of the can 1211 is polygonal. A screw mounting hole is provided in the can 1211 to be connected, and the needle mounting tube 1213 can be mounted on the outer ring of the can 1211 through the screw mounting hole. Wherein the mounting position of the needle mounting tube 1213 corresponds to the position of the vertex of the inner ring of the can 1211. Since the inner ring of the can 1211 has a polygonal shape, the flowing direction of the spinnable liquid in the can 1211 is not a normal direction but a direction toward the vertex, that is, a direction of the needle mounting tube 1213 corresponding to the vertex. Thus, during spinning of the silk-like micro-nano fiber material, the working device 20 does not have spinnability liquid deposited on the inner wall of the can 1211 and formed gel, and eventually blocks the screw mounting hole, so that the spinning member 121 cannot work normally.
Thus, the technical effect that the deposition of the spinnability liquid on the inner wall of the can 1211 and the formation of gel can be prevented by the above-described product structure is achieved, and thus the normal operation of the spinning part 121 can be ensured.
Further, since the outer circumference of the can 1211 of the spinning device 20 is also circular in the related art, the needle mounting tube 1213 is in line contact with the outer wall of the can 1211. Since the needle mounting tube 1213 is in line contact with the outer wall of the can 1211, the spinning member 121 may be loosely mounted to the needle mounting tube 1213 during rotation.
The outer ring of the can 1211 in the present application is preferably selected to be polygonal, and the needle mounting tube 1213 is provided on the face of the outer ring of the polygonal can 1211. Thus, there is surface contact between the needle mounting tube 1213 and the canister 1211, and no gap exists between the needle mounting tube 1213 and the outer wall of the canister 1211. And since the sealing process is performed between the needle mounting tube 1213 and the can 1211 by using the sealing ring, there is no occurrence of a situation that the needle mounting tube 1213 is not firmly mounted or the spinnable liquid stored in the can 1211 flows out of the slit.
Optionally, the feeding part 122 includes: a feed tube 1221, a feed tube port 1222, and a peristaltic pump 1223, wherein the peristaltic pump 1223 is coupled to the feed tube 1221; and a feed conduit 1221 disposed below the canister 1211 in a non-contact manner and delivering the spinnable liquid into the canister 1211 via the feed conduit 1222.
Specifically, referring to fig. 4, the feeding part 122 is mainly composed of a feed pipe 1221, a feed pipe port 1222, and a peristaltic pump 1223. Peristaltic pump 1223 is primarily used to pump the spinnable liquid into tank 1211, and feed tube 1221 is primarily used to deliver the spinnable liquid. Wherein the input rate of the spinnability liquid can be controlled by the kinetic parameters of peristaltic pump 1223.
The worker adds the spinnability liquid to peristaltic pump 1223, and peristaltic pump 1223 pumps the spinnability liquid into feed tube 1221, with the spinnability liquid flowing along feed tube 1221 to feed port 1222 and from feed port 1222 into canister 1211. Wherein the feed introduction port 1222 is disposed inside the can 1211 without contact. Since the spinning member 121 is rotated at a high speed, the feed port 1222 is fixed. Therefore, if the spinning member 121 is in contact with the feed port 1222, a strong friction must be generated. Not only can cause potential safety hazards, but also noise can be generated. However, since the material guiding pipe 1222 and the tank 1211 are disposed in a non-contact manner in this embodiment, the potential safety hazards are greatly reduced, and the service lives of the feeding part 122 and the spinning part 121 are prolonged.
Therefore, the technical effect that the feeding rate can be controlled through the product structure is achieved, and the continuous micro-nano fiber material at the production position of the spinning package 120 is further ensured.
Optionally, the method further comprises: a sensor 60, wherein the sensor 60 is configured to measure the depth of the spinnability liquid in the tank 1211, and the sensor 60 is configured to be disposed inside the tank 1211, and detect the depth of the spinnability liquid in the tank 1211 by contact; or outside the can 1211, and the depth of the spinnable liquid within the can 1211 is detected in a non-contact manner.
Specifically, referring to fig. 2, the sensor 60 is disposed outside the can 1211, and the sensor 60 is mainly used to measure the depth of the spinnability liquid within the can 1211. Wherein the sensor 60 is a non-contact sensor. Among other things, there is a maximum threshold and a minimum threshold for the depth of the spinnability liquid that can be stored by the canister 1211. The depth of the spinnability liquid stored in the tank 1211 cannot be greater than the maximum threshold value and cannot be less than the minimum threshold value.
When the depth of the spinnability liquid in the tank 1211 reaches a maximum threshold, the supply 122 no longer delivers the spinnability liquid to the interior of the tank 1211; after the spinnable liquid in the tank 1211 is ejected by the spinning section 121, the depth of the spinnable liquid in the tank 1211 gradually decreases. When the sensor 60 measures that the depth of the spinnability liquid reaches the minimum threshold, the feeding unit 122 again delivers the spinnability liquid to the inside of the tank 1211 until the depth of the spinnability liquid in the tank 1211 reaches the maximum threshold.
Thus, the technical effect of ensuring continuous spraying of the spinnability liquid in the can 1211 is achieved by the above-described product structure.
Preferably, the sensor 60 may be a touch sensor. When the sensor 60 is a touch sensor, it is disposed inside the can 1211.
Optionally, the method further comprises: and a dehumidifying device 70, the dehumidifying device 70 being connected to the cabinet 50 for supplying dry air.
Specifically, referring to fig. 1, a dehumidifying apparatus 70 is connected to a side wall of the case 50, and the dehumidifying apparatus 70 serves to supply dry air. In this way, the whole operation device 10 can be ensured to operate in a constant and relatively stable dry environment, so that the spinnability of the spinnability liquid is ensured, the spinnability of the spinnability liquid is also prevented from being entangled with each other to form mucus, and finally the stability and uniformity of the structure and the morphology of the collected micro-nano fiber material are ensured.
Therefore, the product structure can provide dry air, so that the spinnability of spinnability liquid is ensured, and the technical effects of stability and uniformity of the prepared micro-nano fiber material are also ensured.
Optionally, the dehumidifying device 70 includes: a dehumidifier 710 and an exhaust pipe 720, wherein the dehumidifier 710 is connected with the exhaust pipe 720; and the exhaust duct 720 is connected with the case 50.
Specifically, referring to fig. 1, the dehumidifying apparatus 70 is composed of a dehumidifier 710 and an exhaust pipe 720. Wherein the dehumidifier 710 is used to discharge the dry air into the cabinet 50 through the air discharge pipe 720.
Thus, the technical effect of providing a dry environment is achieved by the product structure.
