DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0033] A secondary cable core straightening device, such as Figure 1 and Figure 2As shown, it includes a base 1, a fixing component 2, a support plate 3 and a straightening mechanism 4. Three fixing components 2 for installation and fixation are connected by bolts on the front and rear sides of the base 1. The fixing components 2 include mounting plates and threaded pins. Three mounting plates are connected by bolts on the front and rear sides of the base 1. Threaded pins for installation and fixation are threadedly connected on the mounting plates. Support plates 3 are connected to the upper sides of the left and right parts of the base 1. A straightening mechanism 4 for straightening the secondary used cable core and removing indentations is provided on the support plate 3 on the left.

[0034] It should be noted that when a used cable is to be reused, the cable needs to be straightened. At this time, the present device can be used to assist the operator in the operation. First, the base 1 is mounted on the operating platform through the fixing component 2, and then the straightening mechanism 4 is unfolded. Then, the cable is placed on the straightening mechanism 4, and then the straightening mechanism 4 is controlled to close to clamp the wire core. Then, the cable is pulled to the right, and the wire core is straightened by the straightening mechanism 4. The indentations on the wire core are squeezed out to avoid the indentations affecting the secondary use of the cable.

[0035] like Figure 1 and Figure 3 As shown, the straightening mechanism 4 includes a fixed seat 41, a sliding seat 42, an adjusting rod 43, a first guide rod 44, a roller 45 and a gear 46. The top of the left support plate 3 is connected to the fixed seat 41 by bolts, the upper rear side of the fixed seat 41 is connected to the first guide rod 44, the front of the fixed seat 41 is rotatably connected to the adjusting rod 43, the bottom of the adjusting rod 43 is provided with an anti-slip groove, the first guide rod 44 is slidably connected to the sliding seat 42 for cooperating with the fixed seat 41 to press the wire core, the front side of the sliding seat 42 is threadedly connected to the adjusting rod 43, and the front and rear sides of the fixed seat 41 and the sliding seat 42 are rotatably connected with rollers 45 for squeezing and removing the indentations on the wire core, and the rear sides of the rollers 45 are connected to gears 46, and the gears 46 are meshed with each other.

[0036] It should be noted that when straightening the cable core, the adjusting rod 43 is first rotated so that the sliding seat 42 drives the upper roller 45 to slide upward along the first guide rod 44 away from the fixed seat 41, and then the wire cores are spread out and placed on the fixed seat 41, and then the adjusting rod 43 is rotated in the opposite direction so that the sliding seat 42 slides downward along the first guide rod 44 and resets, thereby cooperating with the fixed seat 41 to clamp and press the wire core. After that, the operator holds the end of the cable and pulls the wire core to the right. During the movement of the wire core, it will be straightened under the cooperation of the sliding seat 42 and the fixed seat 41. When the wire core passes through the sliding seat 42 and the fixed seat 41, it will move between the rollers 45. By pulling the cable, the wire core moves between the rollers 45, so that the upper and lower rollers 45 start to rotate in opposite directions under the action of the gear 46, and then the indentations on the wire core are squeezed and smoothed to avoid the indentations affecting the secondary use of the cable. In summary, the scattered wire cores are clamped and pressed by the sliding seat 42 and the fixed seat 41, so that when the operator pulls the cable to the right, the wire core is straightened. After the straightening process, the wire core will pass through the rollers 45, and the indentations will be smoothed under the squeezing action of the rollers 45. At the same time, the rollers 45 can further straighten the wire core and achieve the effect of removing the indentations, so as to avoid the indentations affecting the secondary use of the cable.

[0037] like Figure 1 and Figure 4 As shown, it also includes a traction mechanism 5, which includes a drive assembly 51, a screw rod 52, a second guide rod 53, a sliding frame 54, a clamping assembly 55, a winding wheel 56, a cable 57 and a torsion spring 58. The support plates 3 are rotatably connected with the screw rod 52, and the right side of the screw rod 52 passes through the adjacent support plate 3. The drive assembly 51 is connected between the screw rod 52 and the support plate 3 on the right side. The drive assembly 51 includes a drive motor, a transmission wheel and a transmission belt. The top of the support plate 3 on the right side is connected to the drive motor by bolts. The output shaft of the drive motor and the right end of the screw rod 52 are both connected to the transmission wheel. A transmission belt is wound between the transmission wheels. The second guide rod 53 is connected between the inner sides of the front and rear parts of the support plate 3, and the second guide rods 53 are slidably connected to each other. There is a sliding frame 54 for placing the cable end, the sliding frame 54 is threadedly connected to the screw rod 52, and the sliding frame 54 is connected to a clamping assembly 55 for clamping and fixing the cable end. The clamping assembly 55 includes a threaded rod, a guide column and a clamping plate. The upper rear side of the sliding frame 54 is connected to the guide column, and the front of the sliding frame 54 is rotatably connected to the threaded rod. The guide column is slidably connected to the clamping plate, and the front of the clamping plate is threadedly connected to the threaded rod. The front side of the right support plate 3 is rotatably connected to a winding wheel 56, and a cable 57 is connected between the winding wheel 56 and the left front side of the sliding frame 54. A torsion spring 58 is connected between the cable 57 and the front of the roller 45 wound around the lower side, the winding wheel 56 and the support plate 3 on the right side, and the torsion spring 58 is wound around the winding wheel 56.

[0038] The cable 57 is then pulled out of the reel 56 and the torsion spring 58 is deformed under the force of the torsion spring 58. When the cable 57 is pulled out, the cable 57 drives the lower roller 45 to rotate, thereby causing the upper roller 45 to rotate in the opposite direction under the action of the gear 46. It should be noted that in the process of the sliding frame 54 sliding to the right, the sliding frame 54 cooperates with the clamping assembly 55 to drive the cable end to move to the right, thereby automatically The cable is pulled to achieve the effect of automatic straightening and removing indentations, thereby improving operational efficiency. After straightening is completed, the drive assembly 51 is turned off, and the clamping assembly 55 is controlled to open so that the clamping assembly 55 no longer clamps the cable end. After the straightened cable core is taken out, the drive assembly 51 is controlled to drive the screw rod 52 to rotate in the opposite direction, so that the sliding frame 54 slides to the left along the second guide rod 53 and resets. At this time, the cable 57 is no longer pulled. Under the action of the torsion spring 58, the winding wheel 56 rotates in the opposite direction and rewinds the cable 57. In summary, by controlling the clamping assembly 55 to cooperate with the sliding frame 54 to clamp and fix the cable end, the drive assembly 51 then drives the screw rod 52 to rotate so that the sliding frame 54 automatically slides to the right, thereby pulling the cable. During the pulling process, the cable drives the roller 45 to rotate automatically, thereby achieving the effect of automatically straightening the cable core and removing indentations, thereby improving operational efficiency.

[0039] like Figure 1 and Figure 5 As shown, it also includes a skin-breaking mechanism 6, which includes a connecting frame 61, a skin-breaking tool 62 and a stabilizing plate 63. Five connecting frames 61 are evenly connected to the top of the sliding seat 42 by bolts. The bottom of the connecting frame 61 is connected to a skin-breaking tool 62 for cutting and breaking the protective skin layer on the wire core. A stabilizing plate 63 for improving stability is connected between the upper left sides of the connecting frame 61.

[0040] It should be noted that when placing the cable, as the sliding seat 42 slides upward, the connecting frame 61 and the skin-breaking tool 62 will both move upward. After the cable core is placed, as the sliding seat 42 slides downward to reset, the skin-breaking tool 62 will be clamped with the corresponding core. When the cable core is automatically pulled to the right, the protective cortex on the core is cut and removed by the skin-breaking tool 62, which is convenient for replacing a new protective cortex when the cable is used for a second time, avoiding aging of the protective cortex due to long-term use, resulting in reduced protection effect. In summary, the cable automatically moves to the right, so that the upper side of the core can contact the skin-breaking tool 62, so that during the movement of the cable core, the protective cortex on the core is cut and broken by the skin-breaking tool 62, which is convenient for subsequent replacement of a new protective cortex, thereby increasing the safety of the cable when it is used for a second time.

[0041] like Figure 1 and Figure 6 As shown, it also includes a winding mechanism 7, which includes a connecting plate 71, a winding frame 72 and a servo motor 73. The right part of the base 1 is connected to the connecting plate 71 by bolts, and the top of the connecting plate 71 is connected to the winding frame 72 for winding the straightened cable core by bolts. A spool is rotatably connected to the winding frame 72, and a servo motor 73 is connected to the front side of the winding frame 72 by bolts. The output shaft of the servo motor 73 is connected to the spool.

[0042] It should be noted that after the cable core is straightened, the end of the cable is wound on the winding frame 72, and then the servo motor 73 is started so that the output shaft of the servo motor 73 drives the spool on the winding frame 72 to rotate, thereby winding the straightened cable core to avoid the cable being scattered and inconvenient to collect.

[0043] like Figure 1 and Figure 7 As shown, it also includes a skin guide mechanism 8, which includes a connecting block 81 and a baffle 82. The tops of the frontmost and rearmost connecting frames 61 are connected to the connecting blocks 81 by bolts, and baffles 82 are connected between the connecting blocks 81 for guiding and collecting the protective skin layer after cutting.

[0044] It should be noted that after the skin-breaking tool 62 cuts the protective cortex on the wire core, the cut protective cortex will fall downward due to gravity. At this time, the baffle 82 can guide the cut protective cortex waste, making it easier for the operator to collect the waste.

[0045] like Figure 1 and Figure 8As shown, a protective mechanism 9 is also included, which includes a fixing plate 91 and a protective frame 92. The upper right side of the connecting plate 71 is connected to the fixing plate 91 by bolts, and the top of the fixing plate 91 is connected to the protective frame 92 for protecting the cable core when it is wound.

[0046] It should be noted that as the winding frame 72 begins to collect the straightened cable cores, in order to prevent the ends of the cable cores from being thrown out due to the inertia of rotation, the protective frame 92 is used to shield and protect the right side of the winding frame 72, thereby shielding and limiting the straightened cable cores.

[0047] A method for using a secondary cable core straightening device, the specific steps are as follows:

[0048] Step 1: Install and fix the device using the fixing assembly 2, then rotate the adjusting rod 43 to slide the sliding seat 42 upward, and then control the clamping assembly 55 to expand;

[0049] Step 2: Spread the loose strands of the cable core and place them on the fixing seat 41. Place the end of the cable on the sliding frame 54. Then, control the sliding seat 42 to slide downward to compress the cable core. Control the clamping assembly 55 to close and clamp the cable end.

[0050] Step 3: Start the drive assembly 51 to rotate the screw 52, ​​allowing the sliding frame 54 to slide along the second guide rod 53 and pull the cable 57, thereby causing the roller 45 to rotate in the opposite direction. At the same time, the cable is pulled to the right. During the pulling process, the fixed seat 41 and the sliding seat 42 perform preliminary straightening of the wire core. The roller 45 performs secondary straightening of the wire core and smoothes the indentation. The skin-breaking cutter 62 cuts and removes the protective skin layer of the wire core, and the baffle 82 collects and guides the waste.

[0051] Step 4: After the straightening is completed, the end of the cable is wound on the winding frame 72, and the servo motor 73 is started to reel in the processed cable core.

[0052] The technical principles of the embodiments of the present invention have been described above in conjunction with specific embodiments.
