Description

Technical Field

[0001] This invention relates to the field of graphene fiber preparation technology, specifically to a graphene conductive fiber production equipment. Background Technology

[0002] Graphene fibers are mostly produced using a coating / impregnation method, in which conventional fibers are immersed in a graphene conductive slurry to form a conductive layer on their surface.

[0003] The core performance of graphene conductive fibers lies in their high 8×10 5 Its conductivity of S / m makes it approximately twice as conductive as copper, giving it a significant advantage in lightweight conductive materials. Furthermore, it also possesses high strength and flexibility, as well as excellent electrothermal and thermal management capabilities.

[0004] References such as CN201520967032.9, "Fiber Processing Apparatus and System for Preparing Graphene Fibers and Graphene Oxide Fibers," disclose an ionic liquid wetting and gelling system that wets the linear products extruded by the extrusion system in an ionic liquid; and a fiber stretching and collecting system that stretches and collects the ionic liquid-wetted linear products. This system achieves the preparation of graphene fibers of various diameters and the stretching effect on virgin fibers. Fiber preparation and stretching are achieved in a single line, resulting in fibers with stable properties and enabling continuous production.

[0006] Existing technologies involve processing and twisting raw material threads and then combining them with graphene slurry to produce graphene conductive fibers. However, these technologies have the following problems:

[0007] 1. There is currently a lack of tensile and resistance testing methods for graphene conductive fibers;

[0008] 2. Existing winding machines only stretch the graphene conductive fibers horizontally before winding, without stretching them at multiple angles. This makes them prone to accumulating and stacking at one end during winding.

[0009] 3. The existing constraint uses a pagoda spring to squeeze the pressure plate to vertically constrain the raw material line, which serves to clamp and guide the line and adjust the movement speed of the subsequent raw material line. The raw material line is not tensioned horizontally and vertically. Insufficient tension will result in insufficient contact area for the impregnated graphene, leading to different conductivity.

[0010] 4. Existing tension controllers have a tapered spring installed at an angle. However, this angled installation can cause the gripper structure to collide with the vertical column during rotation, resulting in rotational blockage.

[0011] To address these issues, we provide a graphene conductive fiber production equipment. Summary of the Invention

[0033] A row of wheels is installed on the side of the support frame facing the vertical column;

[0044] 1. This invention uses a conical spring to connect the extrusion plate and the rotating body. Both the extrusion plate and the rotating body extend into the conical spring to achieve a guiding and stable connection. Initially, the rotating body and the extrusion plate pass parallel to each other through the conical spring, maintaining good alignment. Secondly, the rotation of the knob is restricted to within the mounting opening by the mounting ring. The threaded connection pushes or retracts, causing the extrusion plate to move. A baffle then limits the movement, preventing the extrusion plate from disengaging from the threaded part.

[0045] 2. The raw material line of this invention is first connected to the central ring, then passes through a connecting groove on one side and abuts against the surface of the tensioning wheel, then passes through a connecting groove on the other side and returns to the central ring through the corresponding connecting hole; finally, it passes through the central hole through the row wheel. Three sets of connectors can connect three sets of raw material lines, using the same method to tension the raw material lines, thereby enhancing the mixed graphene effect of the tensioned and discharged raw material lines.

[0046] 3. This invention inserts graphene conductive fibers through a guide wheel on one side, and then the moving wheel turns upward to pass through the guide wheel on the opposite side. The tension of the graphene conductive fibers drives the moving wheel to change height, which can intuitively express the tension level and make it easy for the operator to observe whether it meets the standard.

[0047] 4. The present invention achieves tensioning and recycling of graphene conductive fibers by means of a triangularly distributed steering wheel, a fixed wheel inside a fixed sleeve, and a recycling cylinder; wherein, the nut seat on the lead screw rotates and reciprocates with the roller motor at the end of the lead screw, thereby pulling the graphene conductive fibers to move, and reciprocating along the axis on the surface of the recycling cylinder, thereby uniformly winding them on the surface of the recycling cylinder.

[0079] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0080] Example 1

[0081] Please see Figure 1-4 As shown in Figures 8-14, this invention provides a technical solution:

[0082] like Figure 1 As shown, a graphene conductive fiber production device is horizontally displayed, comprising:

[0083] Wire feeder 10, with multiple turns of raw material wire 100 wound around its surface;

[0084] Tension controller 120 guides and constrains the direction and tension of the raw material line 100;

[0085] Graphene immersion chamber 30;

[0086] Drying oven 40;

[0087] Tension controller 250;

[0088] Resistance detector 60 is used to detect the resistance of graphene conductive fiber 200;

[0089] The take-up device 70 winds and recycles the graphene conductive fiber 200. A smart monitoring control screen can also be added to monitor in real time the speed at which the raw material line enters the graphene impregnation tank, the remaining graphene slurry, tension detection, real-time resistance data, and take-up completion status. This is achieved by installing corresponding sensors or cameras at various points for detection. For example, resistance data is transmitted digitally via signal lines and then encoded before being decoded to obtain the data information. Take-up completion can be observed using a camera. The actual layout is not limited to a single horizontal orientation; it can also include bends, requiring the use of bend rollers to adjust the direction of the raw material line 100 or the graphene conductive fiber 200.

[0090] like Figure 2 The diagram shown is a structural diagram of a tension controller 1. The tension controller 1 20 includes a lower housing 1, a base plate 11 installed at the bottom, and an installation cavity opened at the top, with an adjuster 2 installed laterally.

[0091] The upper shell 3 has multiple sets of vertical columns 36 fixedly installed on the top, and a strip groove 32 is provided between adjacent vertical columns 36; a guide extrusion box 4 is detachably installed at the end, a tensioning wheel 47 and a row wheel 48 are installed inside the guide extrusion box 4, and a constraint plate 43 is installed on the top. The constraint plate 43 constrains the raw material line 100 through the tensioning wheel 47 and the row wheel 48 and through the guide extrusion box 4.

[0092] like Figure 4 As shown, the rotating body 8 has a rotating shaft 81 mounted at its bottom, which constrains its rotation within the mounting cavity. A gripper rod 82 is mounted at the top of the rotating body 8, and the top of the gripper rod 82 passes through and moves within a strip groove 32. The gripper rod and the vertical column form a shark gripper shape, creating a rotational-constrained material line effect. Figure 3 Mainly presented in Figure 2 The position gripper bar rotates to form a longitudinal limit, which constrains but does not block the passage of the raw material line.

[0093] A conical spring 9 is installed between the regulator 2 and the rotating body 8. The conical spring connects the regulator and the rotating body respectively, and serves to connect and adjust the pressure of the rotating body 5.

[0094] like Figure 4 As shown, the lower housing 1 has a side mounting opening 12, the adjuster 2 includes an adjusting rod, the adjusting rod is constrained to rotate within the mounting opening 12, and is provided with a threaded part 21; an extrusion plate 24 is mounted on the adjusting rod, the extrusion plate 24 has a threaded hole and is threadedly connected to the threaded part 21.

[0095] like Figure 8 As shown, when the constraint plate is opened, a guide cavity is provided inside the guide extrusion box 4. The two ends of the guide cavity extend to the two ends of the guide extrusion box 4 and are provided with a central hole 44. A support frame 45 is installed in the guide cavity, and a tensioning wheel 47 is installed at the end of the support frame 45.

[0096] A set of rollers 48 is installed on the side of the support frame 45 facing the vertical column 36; in this embodiment, three sets of rollers are arranged along the axial direction of the central hole. A bearing plate is installed outside the rollers, and a drive shaft is provided on the top of the bearing plate. The rollers rotate on the bearing plate through the drive shaft; mounting holes are opened on the bearing plate to position them in the guide cavity.

[0097] like Figure 2 As shown, a compression threaded shaft 37 is installed on the outer side of the guide compression box 4, and a collar portion 431 is installed on one side of the constraint plate 43. The collar portion 431 is sleeved on the compression threaded shaft 37. A position knob 38 is installed on the compression threaded shaft 37 and is threadedly connected to the compression threaded shaft 37 to limit the position of the constraint plate 43 downward. Furthermore, in conjunction with... Figure 8 As you can see, there are vertical guide holes inside to accommodate the insertion and installation of the constraint plate.

[0098] like Figure 8 As shown, the guide extrusion box 4 is laterally mounted with an installation plate 46, and the upper housing 3 is mounted with an installation plate 35 at the end away from the guide extrusion box 4. Both the installation plate 46 and the installation plate 35 are detachably connected to the upper housing 3. Positioning holes are provided at both ends of the bottom plate 11.

[0099] like Figure 7-9 As shown, the support frame 45 is cross-shaped, with a central ring 451 in the middle and a connecting hole on the central ring 451; the support frame 45 has a connecting groove 452 that extends to the end facing the tension wheel 41. Figure 7 and 9 The image shows three sets of directional connectors, with tensioning wheels installed at the ends of the connectors, forming an adjacent angle of 90°. (Example) Figure 13 As shown, connecting grooves are formed on both sides of the connector, and these connecting grooves extend into the central ring through connecting holes. Figure 14The winding distribution involves first connecting to the central ring, then passing through a connecting groove on one side to abut against the surface of the tensioning wheel, then passing through a connecting groove on the other side and returning to the central ring through the corresponding connecting hole; finally, it passes through the central hole via the row wheel. Three sets of connectors can connect three sets of raw material lines, using the same method to tension the raw material lines and achieve a hybrid graphene effect that enhances the output raw material lines.

[0100] Example 2

[0101] like Figure 1-7 As shown, this is another embodiment of the present invention, such as... Figure 6 As shown, the extrusion plate 24 has a mounting groove ring 241 on the side facing the rotating body 8, and the rotating body 8 has a mounting groove ring 83 on the side facing the extrusion plate 24; the outer diameter of the mounting groove ring 241 is larger than the outer diameter of the mounting groove ring 83, which is adapted to the different sizes of the ends of the conical spring 9, ensuring connection alignment and stability, and avoiding collision between the clamping rod and the vertical column after installation, which would cause the extrusion fixing inclined plate to be blocked;

[0102] Constraint opening slots 13 are provided at both ends of the mounting cavity to fit the mounting shaft 81; a mounting port 14 is installed on the side of the lower housing 1 that is opposite to the mounting port 12; a fixing inclined plate 84 is fixedly installed on the side of the rotating body 8 that is opposite to the conical spring 9, and the fixing inclined plate 84 passes through the mounting port 14.

[0103] like Figure 6 As shown, the top of the rotating body 8 is inclined and tilts upwards towards the fixed inclined plate 84 to ensure the initial connection effect; the gripper rod 82 is provided in multiple sets and the number is consistent with the strip groove 32.

[0104] like Figure 6 As shown, the adjusting rod includes a knob part 22 and a mounting ring part 23, with the mounting ring part 23 constrained within the mounting opening 12; the knob part 22, the mounting ring part 23, and the threaded part 21 are integrally formed, with the knob part 22 extending out of the lower housing 1; a guide plate 242 is provided on the extrusion plate 24, and a side plate 33 is provided on the upper housing 3, with a guide groove 34 provided on the side plate 33, and the guide plate 242 is installed and slides within the guide groove 34; the end of the adjusting rod away from the knob part 22 is inserted into the conical spring 9.

[0105] like Figure 4 The inner wall of the mounting cavity is equipped with two sets of baffles 15. The two sets of baffles 15 are used to restrict the movement of the extrusion plate 24 toward the rotating body 8. The distance between the two sets of baffles is less than the length of the extrusion plate. The distance between the baffles 15 and the rotating body 8 is greater than the distance from the end face of the spiral part toward the rotating body 8 to the rotating body 8.

[0106] In this embodiment, a conical spring is used to connect the extrusion plate and the rotating body. Both the extrusion plate and the rotating body extend into the conical spring to achieve a guiding and stable connection. Initially, the rotating body and the extrusion plate pass parallel to each other through the conical spring, maintaining good alignment. Furthermore, the rotation of the knob is restricted to within the mounting opening by the mounting ring. The threaded connection pushes or retracts, causing the extrusion plate to move, and a baffle further limits its movement, preventing the extrusion plate from disengaging from the threaded part.

[0107] In use, the raw material wire is first threaded through the central hole on one side, then tensioned by the corresponding connector, and then extended through the guide extrusion box via the rollers; subsequently, it passes between the vertical column and the gripper bar, and then through the tension controller through the second mounting plate. It is then dried in the drying oven; the tension controller then uses a winding gauge to measure tension changes, a resistance detector to check conductivity, and finally a take-up device to recover the graphene conductive fiber.

[0108] Example 3

[0109] like Figure 15-21 As shown, this is another embodiment of the present invention, based on embodiment 2.

[0110] like Figure 15 As shown, the graphene impregnation tank 30 has an internal accommodating cavity filled with graphene slurry 31 for the raw material line 100 to pass through.

[0111] like Figure 16 As shown, the drying chamber 40 has an internal drying chamber 41 and an external online temperature control cabinet 42. A temperature control sensor is embedded in the surface and extends into the drying chamber 41 to monitor the temperature and transmit it to the online temperature control cabinet. The online temperature control cabinet can display the temperature at the corresponding position through a display panel on its surface. The raw material line 100 used for impregnating graphene is dried into graphene conductive fiber 200.

[0112] like Figure 17As shown, the tension controller 50 includes a position frame 51 and a position frame 52. Guide wheels 53 are mounted on both position frames 51 and 52, and the guide wheels 53 movably abut against the graphene conductive fiber 200. A constraint clamp 54 is mounted on position frame 51, and a position post 55 is movably connected inside the constraint clamp 54. A rotating clamp 56 is hinged to the end of the position post 55, and a swing rod 57 is clamped inside the rotating clamp 56. A moving wheel 58 is connected to the end of the swing rod 57 away from the rotating clamp 56. If the load is insufficient, a weight can be added to the moving wheel to increase its mass. The moving wheel 58 movably abuts against the graphene conductive fiber 200. The graphene conductive fiber enters from the right side and then passes upwards through the moving wheel, passing through the guide wheel on the opposite side. When the graphene conductive fiber is loose, the downward rotation of the swing rod causes the moving wheel to descend; when the graphene conductive fiber is tight, the upward rotation of the swing rod causes the moving wheel to rise. Initially, the constraint clamp is manually opened and a position post is installed.

[0113] like Figure 18-21 As shown, the take-up device 70 includes a fixed frame 71, on which a steering wheel 72 is mounted, and a winding roller 73 is mounted on its lower side. A rotary motor 74 is mounted at the end of the winding roller 73, driving the winding roller 73 to rotate. A recovery cylinder 75 is detachably mounted on the winding roller 73, and graphene conductive fiber 200 is wound around the recovery cylinder 75. A lead screw 76 is mounted laterally on the winding roller 73, and the end of the lead screw 76 passes through the fixed frame 71 and is coaxially mounted with a winding roller motor, which controls the forward and reverse rotation of the lead screw 76. A nut seat 77 is mounted on the lead screw 76, and a fixed sleeve 78 is mounted on the nut seat 77. A fixed wheel 79 is installed inside the fixed sleeve 78, and the fixed wheel 79 movably abuts against the graphene conductive fiber 200. In this embodiment, the steering wheel, the fixed wheel inside the fixed sleeve, and the recovery cylinder are arranged in a triangular pattern, as shown in the figure. Figure 20 As shown, the graphene conductive fiber is tensioned and recycled; the nut seat on the screw rotates and reciprocates with the roller motor at the end of the screw, thereby pulling the graphene conductive fiber to move and reciprocate along the axis on the surface of the recycling cylinder, thus uniformly winding it on the surface of the recycling cylinder.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
