The drying source is arranged in the drying chamber 131 and is used to dry the conductive rod passing through the drying chamber 131.

The cutting module 140 includes a third limiting hole 141, a traction mechanism 142, a cutting actuator 143 and an infrared sensing mechanism 146 arranged in sequence along the first direction.

[0049] For details, please refer to Figure 1 and Figure 2The pay-off bracket includes a base 111, a vertical bracket 112 and a horizontal bracket 113. The vertical bracket 112 is vertically fixed on the base 111, and the horizontal bracket 113 is vertically fixed on the vertical bracket 112. The pay-off roller 114 and the limit lock 115 are arranged on the horizontal bracket 113. Two limit locks 115 are arranged on both sides of the pay-off roller 14. The limit lock 115 is configured to be able to move only along the axial direction of the pay-off roller 114. By moving the limit lock 115, the limit lock 115 is in contact with the pay-off roller 114 and the axial pressure between the two is changed, and the friction generated by the contact between the limit lock 115 and the pay-off roller 114 can be changed, so that the pay-off tension can be adjusted. It can be understood that the tension of the fiber / conductive rod during the travel process is proportional to the friction between the limit lock 115 and the pay-off roller 114. Exemplarily, 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 all known to those skilled in the art and are not limited here.

[0050] Specifically, the pay-off roller 14 is preferably a cylindrical tube structure with open ends, and the limit lock 115 is preferably a conical structure. The conical tip of the limit lock 115 faces the pay-off roller 14 and extends into the pay-off roller 114, so that the two maintain a good contact state and avoid relative displacement of the two production lines in the radial direction.

The limiting rod 125 is arranged inside the sizing tank 121, and the first limiting hole 123 and the shaping channel 126 are located in the same horizontal plane. The horizontal height of the position of the limiting rod 125 is lower than the horizontal height of the position of either the first limiting hole 123 or the shaping channel 126. The first limiting hole 123 and the limiting rod 125 are arranged on the downstream side of the sizing tank 121. 125 and the shaping channel 126 are configured to form a sizing guide structure for guiding the fiber to pass through the sizing tank 121, and a tensioning structure for maintaining a specified tension when the fiber passes through the sizing tank 121. Through such a design, the limit rod 125 can make the fiber 201 always immersed in the sizing agent located in the sizing tank 121 when passing through the sizing tank 121, and extrude the gas entrained in the fiber 201, so that the fiber 201 is fully wetted by the sizing agent. The fiber after being immersed in the sizing agent passes through the shaping channel 126, and the cross section shrinks in the shaping channel 126, and the excess sizing agent is squeezed out and is initially shaped into a wet and uncured conductive rod 202. It can be understood that the shaping channel 126 determines the diameter and roundness of the cross section of the conductive rod 202. Exemplarily, the shaping channel 126 can be arranged in 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 required conductive rod.

Specifically, by providing the guide pulley 122, the fiber 201 contacts the guide pulley 122, which can reduce the contact friction of the fiber and reduce the wear of the fiber.

[0053] It should be noted that the areas directly in 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 the wear caused by the fiber contacting with other mechanisms.

The swing mechanism 123 is used to drive the fiber in the sizing tank 121 to shake or vibrate along the second direction. By shaking the fiber 201 horizontally along the second direction, it can strengthen its contact with the sizing agent, release the air inside the fiber, and at the same time, enhance the flow of the sizing agent near the fiber, so that the concentration of the sizing agent and the solution body near the fiber is more evenly distributed. More specifically, the swing mechanism 123 includes a swing component and a first drive component, the first drive component is connected to the swing component in a transmission manner, and the swing component swings under the drive of the first drive component, and the fiber's travel trajectory in the sizing tank 121 intersects with the swing trajectory of the swing component.

More specifically, the drying source may also include a height adjustment frame 134, which is arranged in the drying chamber 131, and the electric heating mechanism 132 is arranged on the height adjustment frame 134, and the height adjustment frame 134 is used to drive the electric heating mechanism 132 to rise and fall, so as to change the distance between the electric heating mechanism 132 and the conductive rod, thereby changing the temperature of the environment around the conductive rod. More specifically, the drying module 130 also includes a thermocouple 133, which is arranged in the drying chamber 131 and is used to monitor the temperature of the environment around the conductive rod.

[0056] For details, please refer to Figure 5, the cutting actuator 143 is connected to the infrared sensing mechanism 146 for communication, the traction mechanism 142 allows the conductive rod to pass through and provides traction for traction of the fiber / conductive rod to move continuously along the first direction, the infrared sensing mechanism 146 is used to monitor the end position of the conductive rod and send a cutting execution signal to the cutting actuator 143, and the cutting actuator 143 is used to cut 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 traction rollers arranged in parallel, and a gap is formed between the two traction rollers for the conductive rod to pass through and to contact with the conductive rod passing through by friction, wherein at least one traction roller is connected to the second drive assembly in a transmission manner and can rotate around its own axis under the drive of the second drive assembly, the traction for traction of the fiber / conductive rod to move continuously along the first direction comes from the friction between the conductive rod and the traction roller, and the baking time of the conductive rod in the drying module can be controlled by controlling the rotation speed of the traction roller. Exemplarily, the second drive assembly can be a rotary drive motor, etc.

[0057] Specifically, the infrared sensing mechanism 146 may be an infrared sensor, etc., the end of the conductive rod is transmitted to the infrared sensing line, triggering a sensing signal, and the cutting actuator 143 receives the signal of the infrared sensing mechanism 146 to cut the conductive rod. Exemplarily, the cutting actuator 143 may be a pneumatic scissors, etc. For details, please refer to 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 arranged between the cutting modules 140 of adjacent metal composite fiber conductive rod production lines 100 to prevent the multiple infrared sensing mechanisms 146 from influencing each other.

[0058] Specifically, the cutting module 140 may further include a track 145 extending along the first direction, an infrared sensing mechanism 146 is disposed on the track 145, and the infrared sensing mechanism 146 can move along the track 145 and be locked at any position on the track 145, so as to adjust the length of the conductive rod after cutting.

The flip table 144 is used to carry the conductive rods to be cut and cut, and to transfer the conductive rods obtained after cutting to the conductive rod collection mechanism 147. Specifically, after the cutting actuator 143 cuts the conductive rod 202, the flip table 144 flips accordingly, and the conductive rod falls into the conductive rod collection mechanism 147. Exemplarily, the flip table 144 may be a pneumatic flip table 144, etc., and the rotation axis of the flip table 144 is perpendicular to the second direction.

[0060] As a preferred solution, the first limiting hole, the molding channel, the second limiting hole 135 and the third limiting hole 141 are preferably coaxially arranged.

[0061] For details, please refer to Figure 1 The fiber moves along the first direction from the pay-off module 110 under the traction of the traction mechanism 142. The pay-off module 110 allows the fiber to enter the sizing module 120 at a constant speed along the first direction under a constant tension. The pay-off module 110 can control the pay-off tension of the fiber to solve the problem of axial bending of the conductive rod. 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 immersed in the sizing agent. The swing mechanism 123 shakes the fiber 201 horizontally to make it fully sizing. After the wet fiber 201 enters the shaping channel 126, it is initially shaped into a wet conductive rod 202 and enters the drying module 130 along the first direction. The sizing module 120 makes the fiber fully impregnated and shaped to solve the problems of the hollow inside of the conductive rod and the poor roundness of the cross section. The swing mechanism shakes the fiber horizontally to strengthen its contact with the sizing agent and release the air inside the fiber; at the same time, the liquid flow near the fiber is enhanced to make the concentration of the sizing agent near the fiber and the solution body uniform.

[0062] In the drying module 130, the wet conductive rod 202 from the sizing module 120 enters horizontally at a uniform speed along the first direction, and is parallel to the electric heating mechanism 132 inside the drying chamber 131. The wet conductive rod 202 gradually loses water and solidifies, and is finally completely dried. The drying module 130 can dry the wet conductive rod and ensure that the conductive rod does not crack due to baking. The height of the electric heating mechanism 132 is adjustable, and the baking temperature can be accurately controlled by the thermocouple 133; In the cutting module 140, the conductive rods from the drying module 130 pass through the third limiting hole 141, the traction mechanism 142, and the cutting execution mechanism 143, and then reach the infrared sensing mechanism 146, triggering the infrared sensing mechanism 146. After receiving the signal, the cutting execution mechanism 143 immediately cuts the conductive rods, and the turning table 144 turns over accordingly, and the conductive rods with a certain length cut off finally fall into the conductive rod collecting mechanism 147.

[0063] After the fiber is prepared into a conductive rod, there is a problem of conductive rod bending. The bending of the conductive rod is not conducive to downstream use, resulting in an increase in the defective rate. The main factor causing the bending of the conductive rod is that the fiber tension is too low. To address this problem, when the roller carrying the fiber roll rotates around the transverse bracket, the pay-off module in the present invention uses a conical limit lock to adjust the contact friction between the roller and the roller, which can conveniently and flexibly adjust the fiber pay-off tension and effectively solve the problem of conductive rod bending.

[0064] The conductive rod is hollow inside, which makes it easy to bend and deform, affecting the use of the conductive rod. The problems caused by the hollow inside of the conductive rod are that the fiber fails to fully contact the sizing agent, bubbles are contained inside the fiber, and the fiber is not tightly molded. To solve this problem, the limit rod in the present invention immerses the fiber in the sizing agent, the swing mechanism strengthens the contact between the fiber and the sizing agent, and the molding channel squeezes and molds the wet fiber, thereby preparing a wet conductive rod with a tight interior and good molding, solving the problem of the hollow inside of the conductive rod.

[0065] The metal composite fiber is first sizing and moistening, and then passes through a molding tube to squeeze out excess sizing agent, and a wet conductive rod is obtained after preliminary molding. At this time, the conductive rod is in a softened state, and is easily deformed by the size and position of the molding channel, which affects the roundness of the cross section. To address this problem, the present invention designs and horizontally installs a molding channel at the end of the sizing module, and uses molding channels of different sizes to mold fibers of different specifications. After the fiber passes through the molding channel horizontally, it becomes a straight wet conductive rod, and the wet conductive rod continues to enter the drying module in the horizontal direction, solving the problem of poor roundness of the cross section of the conductive rod.

[0066] After the metal composite fiber is shaped, a wet conductive rod is obtained. After being dried and solidified by a drying device, a dry conductive rod is obtained. Finally, a conductive rod product with a certain length is obtained by passing through a conductive rod cutting device. However, during the drying process of the conductive rod, the conductive rod is easily cracked due to too long a baking time or too close a baking distance. In response to this problem, the present invention places two electric heating wires in parallel on both sides of the wet conductive rod. The support frame at the bottom can adjust the height of the electric heating wire, thereby controlling the baking distance between the electric heating wire and the wet conductive rod. A thermocouple is fixed next to the wet conductive rod to monitor its baking temperature in real time. After the wet conductive rod passes through the drying module horizontally and at a uniform speed, a conductive rod with a solidified and neat appearance can be obtained, thereby solving the problem of cracking of the conductive rod. Photos of the metal composite fiber and the conductive rod obtained by processing the metal composite fiber through the present invention are shown respectively as follows: Figure 6a , Figure 6b shown.

[0067] In order to solve the problem of different lengths of conductive rods, when the conductive rods after drying and curing of the present invention enter the conductive rod cutting module, the traction mechanism first transmits the conductive rods forward, and the conductive rods pass through the cutting actuator and are transmitted on the pneumatic flip table. When the front end of the conductive rod reaches the laser sensing line, the laser signal is triggered. After receiving the signal, the cutting actuator randomly cuts the conductive rods. The cutting length error of the conductive rods can be controlled within 5 mm, which meets the product length requirements and solves the problem of different lengths of conductive rods.

[0068] The present invention completes all the processes from fiber pay-off to conductive rod collection automatically, thus saving labor costs. The present invention can simultaneously size, dry, cut and collect conductive rods for multiple rolls of fiber. At the same time, by adjusting the speed of the electric roller and the temperature of the oven, the preparation speed of the conductive rods can be greatly improved. The device of the present invention occupies a small area, has low energy consumption, is easy to operate and maintain, and has safe, stable and pollution-free production and operation, effectively solving the problem of time-consuming, labor-intensive and low-capacity conductive rod preparation.
