[0003] Metal composite fibers are typically woven into sets, fabrics, or laminated with resin to form boards. This invention prepares conductive rods from metal composite fibers, transforming the fibers from a loose, fluffy state into a solidified, shaped form.

[0027] Furthermore, the oscillating component includes two spaced-apart swing arms, which are arranged along a second direction on both sides of the fiber's travel trajectory within the sizing tank.
[0028] In a more specific embodiment, the drying module includes a drying chamber and a drying source, the drying source being disposed in the drying chamber and used to dry the conductive rod passing through the drying chamber.

[0054] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has proposed the technical solution of this utility model. The following will further explain and illustrate the technical solution, its implementation process and principle in conjunction with the accompanying drawings and specific implementation examples. Unless otherwise specified, the components involved in the embodiments of this utility model, such as motors, electric heating tubes, rollers, traction rollers, thermocouples, infrared sensors, pneumatic scissors, and pneumatic tilting tables, are all known in the art and can be obtained commercially. Their specific structures and working principles will not be described in detail here.
[0055] The present invention provides a metal composite fiber conductive rod preparation device, which is applicable to the preparation of conductive rods of carbon fiber, quartz fiber, glass fiber, carbon nanotube fiber and their metal composite fibers, that is, it is suitable for fiber bundles of various materials and specifications.
[0056] In a more typical implementation scheme, please refer to Figure 1 A metal composite fiber conductive rod preparation device includes one or more metal composite fiber conductive rod production lines 100. The multiple metal composite fiber conductive rod production lines 100 can be completely identical, and the multiple metal composite fiber conductive rod production lines 100 can be arranged in parallel at intervals. The following describes and explains the specific structural composition and working process of one of the metal composite fiber conductive rod production lines 100 as an example.
[0057] Specifically, the metal composite fiber conductive rod production line 100 includes a wire feeding module 110, a sizing module 120, a drying module 130, and a cutting module 140 arranged sequentially along a first direction. Fibers 201 and conductive rods 202 / 202 formed from the fibers can be drawn along the first direction from the wire feeding module 110, sequentially through the sizing module 120, the drying module 130, and to the cutting module 140. The wire feeding module 110 is used to carry the fibers and adjust the tension of the fibers / conductive rods during travel. The sizing module 120 is used to provide a sizing agent, fully combine the fibers with the sizing agent to form conductive rods, and shape the conductive rods. The drying module 130 is used to dry the conductive rods. The cutting module 140 is used to provide a traction force to continuously guide the fibers / conductive rods along the first direction and cut the conductive rods 202 to a specified length.
[0058] Please refer to the following for details. Figures 1-5The pay-off module 110 includes a pay-off bracket, a pay-off roller 114, and limit locks 115. The pay-off roller 114 and limit locks 115 are mounted on the pay-off bracket. The pay-off roller 114 is used to carry fibers (mainly fiber rolls 200) and can rotate around its own axis. The two limit locks 115 are located on both sides of the pay-off roller 114 and are movable, allowing them to move axially along the pay-off roller 114 and change their position relative to the roller. The distance and friction between cylinders 114; the sizing module 120 includes a sizing tank 121, a guide pulley 122, a first limiting hole 123, a limiting rod 125, and a shaping channel 126. The sizing tank 121 is used to contain the sizing agent. The guide pulley 122 and the first limiting hole 123 are arranged on the upstream side of the sizing tank 121 along a first direction. The limiting rod 125 is arranged inside the sizing tank 121. The shaping channel 126 is arranged on the downstream side of the sizing tank 121; drying Module 130 includes a drying chamber 131, a drying source, and a second limiting hole 135. The drying source is disposed in the drying chamber 131 and is used to dry the conductive rod passing through the drying chamber 131. The second limiting hole 135 is disposed on the downstream side of the drying chamber 131 along a first direction. The cutting module 140 includes a third limiting hole 141, a traction mechanism 142, a cutting execution mechanism 143, and an infrared sensing mechanism 146, which are sequentially spaced along the first direction. The pay-off roller 114, the guide pulley 122, the first limiting hole 123, the limiting rod 125, the shaping channel 126, the second limiting hole 135, and the third limiting hole 141 form a guiding structure to guide the fiber / conductive rod to travel along the first direction. The traction mechanism 142 is used to provide traction force so that the fiber located on the pay-off roller 114 passes sequentially through the pay-off module 110 and the sizing module 120, so that the formed conductive rod reaches the cutting module 140 via the drying module 130.
[0059] For details, please refer to the following document again. Figure 1 and Figure 2The wire feeding support includes a base 111, a vertical support 112, and a horizontal support 113. The vertical support 112 is vertically fixed to the base 111, and the horizontal support 113 is vertically fixed to the vertical support 112. A wire feeding roller 114 and two limit locks 115 are mounted on the horizontal support 113. The two limit locks 115 are located on both sides of the wire feeding roller 14 and are configured to move only along the axial direction of the wire feeding roller 114. By moving the limit locks 115, they contact the wire feeding roller 114, changing the axial pressure between them. This alters the frictional force generated between the limit locks 115 and the wire feeding roller 114, thereby adjusting the wire feeding tension. It is understood that the tension of the fiber / conductive rod during its movement is directly proportional to the frictional force between the limit locks 115 and the wire feeding roller 114. For example, the vertical support 112 is preferably a vertical shaft, and the horizontal support 113 is preferably a horizontal shaft. The fixing structure and method between the base 111, the vertical support 112 and the horizontal support 113 are known to those skilled in the art and are not limited here.
[0060] Specifically, the pay-off roller 14 is preferably a cylindrical structure open at both ends, and the limiting lock 115 is preferably a conical structure. The conical tip of the limiting lock 115 faces the pay-off roller 14 and extends into the interior of the pay-off roller 114 to maintain good contact between the two and avoid relative radial displacement between them. It can be understood that the maximum radial cross-sectional area of the conical limiting lock 115 is greater than the radial cross-sectional area of the pay-off roller 14. Preferably, the radial cross-sectional area of the middle region of the conical limiting lock 115 is greater than the radial cross-sectional area of the pay-off roller 14. Specifically, based on the configuration of the limiting lock 115 and the pay-off roller 114, the pay-off module 110 enables the fiber 201 to enter the sizing module 120 at a constant speed along the first direction under constant tension. Through the configuration of this utility model, the pay-off module 110 can control the fiber pay-off tension and solve the problem of axial bending of the conductive rod.
[0061] For details, please refer to the following document again. Figure 1 and Figure 3A first limiting hole 123 is disposed on the upstream side of the sizing tank 121 along the first direction (i.e., the fiber travel direction), and a shaping channel 126 is disposed on the downstream side of the sizing tank 121 along the first direction (i.e., the fiber travel direction). A limiting rod 125 is located between the first limiting hole 123 and the shaping channel 126. The limiting rod 125 is disposed inside the sizing tank 121. Furthermore, the first limiting hole 123 and the shaping channel 126 are located on the same horizontal plane. The horizontal height of the limiting rod 125 is lower than the horizontal height of either the first limiting hole 123 or the shaping channel 126. The first limiting hole 123 and the limiting rod... The guide bar 125 and shaping channel 126 are configured to form a sizing guide structure that guides the fiber through the sizing tank 121 and a tensioning structure that maintains a specified tension on the fiber as it passes through the sizing tank 121. Through this design, the guide bar 125 ensures that the fiber 201 is always immersed in the sizing agent located within the sizing tank 121 as it passes through, and also extrudes the gas trapped within the fiber 201, allowing the fiber 201 to be fully wetted by the sizing agent. After being impregnated with the sizing agent, the fiber passes through the shaping channel 126, where its cross-section shrinks, excess sizing agent is extruded, and it is initially shaped into a moist, uncured conductive rod 202. It is understood that the shaping channel 126 determines the diameter and roundness of the conductive rod 202's cross-section. For example, the shaping channel 126 can be disposed within a shaping tube, and the radial cross-sectional shape and area of the shaping channel 126 are the same as the radial cross-sectional shape and area of the desired conductive rod.
[0062] Specifically, the sizing tank 121 has a sizing agent inlet 1211 and a sizing agent inlet 1212 communicating with its internal accommodating cavity. The sizing agent supply mechanism and the filtration mechanism are connected to the sizing tank 121 via the sizing agent inlets 1211 and 1212, forming a loop for the sizing agent to circulate after filtration, thereby reducing the generation of liquid waste and achieving environmentally friendly production. Specifically, by setting a guide pulley 122, the fiber 201 contacts the guide pulley 122, which can reduce the contact friction of the fiber and reduce fiber wear.
[0063] It should be noted that the areas in direct contact with the fiber, such as the first limiting hole 123, the limiting rod 125, and the shaping channel 126, have smooth surfaces to minimize wear caused by the fiber coming into contact with other mechanisms.
[0064] For details, please refer to the following document again. Figure 3The sizing module 120 also includes a swing mechanism 123, disposed within the sizing tank 121 and located between the first limiting hole 123 and the limiting rod 125. The swing mechanism 123 is used to drive the fibers located in the sizing tank 121 to sway or vibrate along a second direction. By horizontally swaying the fibers 201 along the second direction, their contact with the sizing agent can be strengthened, air inside the fibers can be released, and the flow of the sizing agent near the fibers can be enhanced, making the concentration of the sizing agent and the solution near the fibers more uniform. More specifically, the swing mechanism 123 includes a swing component and a first driving assembly. The first driving assembly is connected to the swing component. The swing component sways under the drive of the first driving assembly, and the travel trajectory of the fibers in the sizing tank 121 intersects with the swing trajectory of the swing component. More specifically, the swing component includes two spaced-apart swing rods, which are disposed on both sides of the travel trajectory of the fibers in the sizing tank 121 along the second direction. Exemplarily, the first driving assembly can be a motor, etc., and the first driving assembly is preferably disposed outside the sizing tank.
[0065] For details, please refer to the following document again. Figure 4 The drying source is an electrothermal mechanism 132, which can be a heating wire, heating rod, etc. Preferably, the drying source includes multiple electrothermal mechanisms 132, which are spaced apart and arranged in parallel along a second direction, and distributed on both sides or around the running trajectory of the undried conductive rod 202. More specifically, the drying source may also include a height adjustment frame 134, which is disposed in the drying chamber 131. The electrothermal mechanisms 132 are disposed on the height adjustment frame 134, and the height adjustment frame 134 is used to drive the electrothermal mechanisms 132 to rise and fall, thereby changing the distance between the electrothermal mechanisms 132 and the conductive rod, and thus changing the temperature of the environment around the conductive rod. More specifically, the drying module 130 also includes a thermocouple 133, which is disposed in the drying chamber 131 and is used to monitor the temperature of the environment around the conductive rod.
[0066] For details, please refer to the following document again. Figure 5The cutting execution mechanism 143 is communicatively connected to the infrared sensing mechanism 146. The traction mechanism 142 allows the conductive rod to pass through and provides a traction force to continuously propel the fiber / conductive rod along a first direction. The infrared sensing mechanism 146 monitors the end position of the conductive rod and sends a cutting execution signal to the cutting execution mechanism 143. The cutting execution mechanism 143 cuts the conductive rod passing through the traction mechanism 142. More specifically, the traction mechanism 142 includes a second drive assembly and a traction roller group. The traction roller group includes two parallel traction rollers with a gap between them allowing the conductive rod to pass through and making frictional contact with the passing conductive rod. At least one traction roller is drive-connected to the second drive assembly and can rotate around its own axis under the drive of the second drive assembly. The traction force that propels the fiber / conductive rod continuously along the first direction comes from the friction between the conductive rod and the traction roller. By controlling the rotation speed of the traction roller, the baking time of the conductive rod in the drying module can be controlled. For example, the second drive assembly may be a rotary drive motor, etc.
[0067] Specifically, the infrared sensing mechanism 146 can be an infrared sensor, etc. The end of the conductive rod transmits a signal to the infrared sensing line, triggering a sensing signal. The cutting execution mechanism 143 receives the signal from the infrared sensing mechanism 146 and cuts the conductive rod. For example, the cutting execution mechanism 143 can be a pneumatic scissors, etc. Please refer again for more details. Figure 1 When multiple metal composite fiber conductive rod production lines 100 are set up, in order to avoid the influence between the infrared sensing mechanisms 146 of different metal composite fiber conductive rod production lines 100, a baffle 300 is also set between the cutting modules 140 of adjacent metal composite fiber conductive rod production lines 100 to prevent the multiple infrared sensing mechanisms 146 from affecting each other.
[0068] Specifically, the cutting module 140 may further include a track 145 extending along a first direction, an infrared sensing mechanism 146 disposed on the track 145, and the infrared sensing mechanism 146 being able to move along the track 145 and lock at any position on the track 145, thereby adjusting the length of the cut conductive rod. It should be noted that the specific structure of the track 145 and the configuration structure and method of the infrared sensing mechanism 146 and the track 145 are known in the art and are not specifically limited here.
[0069] Specifically, the cutting module 140 may further include a flipping table 144 and a conductive rod collecting mechanism 147. The conductive rod collecting mechanism 147 is disposed below the flipping table 144, which is disposed downstream of the cutting execution mechanism 143. The flipping table 144 is used to carry the conductive rods to be cut and the cut conductive rods, and to transfer the cut conductive rods to the conductive rod collecting mechanism 147. Specifically, after the cutting execution mechanism 143 cuts the conductive rod 202, the flipping table 144 flips accordingly, and the conductive rod falls into the conductive rod collecting mechanism 147. For example, the flipping table 144 may be a pneumatic flipping table 144, etc., and the rotation axis of the flipping table 144 is perpendicular to the second direction. It should be noted that the pneumatic flipping table 144 is known in the art.
[0070] As a preferred embodiment, the first limiting hole, the molding channel, the second limiting hole 135, and the third limiting hole 141 are preferably coaxially arranged.
[0071] For details, please refer to the following document again. Figure 1 Under the traction of the traction mechanism 142, the fiber travels along the first direction on the wire feeding module 110. The wire feeding module 110 makes the fiber enter the sizing module 120 at a constant speed along the first direction under constant tension. The wire feeding module 110 can control the fiber feeding tension and solve the problem of axial bending of the conductive rod.
[0072] In the sizing module 120, the fiber 201 from the pay-off module passes through the guide pulley 122, the first limiting hole 123, and the limiting rod 124, and is then immersed in the sizing agent. The swing mechanism 123 horizontally shakes the fiber 201 to ensure it is fully sized. After entering the shaping channel 126, the wetted fiber 201 is initially shaped into a moist conductive rod 202 and enters the drying module 130 along the first direction. The sizing module 120 ensures that the fiber is fully impregnated and shaped, solving the problems of hollow interior and poor cross-sectional roundness of the conductive rod. The swing mechanism horizontally shakes the fiber to enhance its contact with the sizing agent and release air inside the fiber. At the same time, it enhances the liquid flow near the fiber, making the concentration of the sizing agent and the solution body uniform near the fiber.
[0073] In the drying module 130, the moist conductive rod 202 from the sizing module 120 enters horizontally and at a uniform speed along the first direction, and is parallel to the electrothermal mechanism 132 inside the drying chamber 131. The moist conductive rod 202 gradually loses water and solidifies, and is eventually completely dried. The drying module 130 can dry the moist conductive rod and ensure that the conductive rod does not crack due to baking. The height of the electrothermal mechanism 132 is adjustable, and the baking temperature can be precisely controlled by using a thermocouple 133.
[0074] In the cutting module 140, the conductive rod from the drying module 130 passes through the third limiting hole 141, the traction mechanism 142, and the cutting execution mechanism 143, and then reaches the infrared sensing mechanism 146. The infrared sensing mechanism 146 is triggered, and the cutting execution mechanism 143 immediately cuts the conductive rod after receiving the signal. The flipping table 144 flips accordingly, and the cut conductive rod of a certain length finally falls into the conductive rod collecting mechanism 147.
[0075] After fibers are processed into conductive rods, the problem of bent conductive rods exists. Bent conductive rods are detrimental to downstream use, leading to an increased defect rate. The main factor causing the bending of the conductive rods is insufficient fiber tension. To address this problem, the fiber feeding module of this invention uses a conical limit lock to adjust the contact friction between the fiber feeding module and the roller as the roller carrying the fiber roll rotates around the transverse support. This allows for convenient and flexible control of the fiber feeding tension, effectively solving the problem of bent conductive rods.
[0076] The hollow interior of the conductive rod makes it prone to bending and deformation, affecting its use. Problems caused by this hollow interior include insufficient contact between the fiber and the sizing agent, air bubbles within the fiber, and loose fiber molding. To address this issue, this invention utilizes a limiting rod to immerse the fiber in the sizing agent, a oscillating mechanism to enhance the contact between the fiber and the sizing agent, and a molding channel to compress and mold the wet fiber. This process produces a dense, well-molded, moist conductive rod, thus solving the problem of the hollow interior.
[0077] Metal composite fibers are first sized and moistened, then excess sizing agent is extruded through a molding tube, resulting in a moist conductive rod after preliminary molding. At this stage, the conductive rod is in a softened state and is easily deformed by the size and position of the molding channel, affecting the roundness of its cross-section. To address this problem, this invention designs and horizontally installs a molding channel at the end of the sizing module, using molding channels of different sizes to mold fibers of different specifications. After the fiber horizontally exits the molding channel, it becomes a straight, moist conductive rod. The moist conductive rod continues horizontally into the drying module, thus solving the problem of poor cross-sectional roundness of the conductive rod.
[0078] Metal composite fibers are shaped to obtain moist conductive rods, which are then dried and cured in a drying device to obtain dry conductive rods. Finally, they are cut into conductive rod products of a certain length by a conductive rod cutting device. However, during the drying process, the conductive rods are prone to cracking due to excessive baking time or insufficient baking distance. To address this problem, this invention places two electric heating wires parallel to each other on both sides of the moist conductive rod. The lower support frame can adjust the height of the electric heating wires, thereby controlling the baking distance between the electric heating wires and the moist conductive rod. A thermocouple is fixed next to the moist conductive rod to monitor its baking temperature in real time. After the moist conductive rod passes horizontally and at a uniform speed through the drying module, a clean and cured conductive rod is obtained, solving the problem of conductive rod cracking.
[0079] To address the issue of inconsistent conductive rod lengths, this invention introduces a new design where, after the conductive rods have dried and cured, they enter the conductive rod cutting module. First, a traction mechanism forward-transmits the conductive rods. The rods then pass through a cutting execution mechanism and are conveyed on a pneumatic flipping table. When the front end of the conductive rod reaches the laser sensing line, a laser signal is triggered. Upon receiving the signal, the cutting execution mechanism randomly cuts the conductive rod. The cutting length error of the conductive rod can be controlled within 5 millimeters, meeting product length requirements and solving the problem of inconsistent conductive rod lengths.
[0080] This invention automates the entire process from fiber unwinding to conductive rod collection, saving labor costs. It can simultaneously sizing, drying, cutting, and collecting conductive rods from multiple fiber rolls. Furthermore, by adjusting the speed of the electric rollers and the oven temperature, the production speed of conductive rods can be significantly increased. The device described in this invention has a small footprint, low energy consumption, is simple to operate and maintain, and ensures safe, stable, and pollution-free production, effectively solving the problems of time-consuming, labor-intensive, and low-yield conductive rod production.
