[0030] Please refer to Figures 1-6 , the present utility model provides a tension control mechanism for cable production, including a frame 1, and further including a mounting frame 2.

A plurality of symmetrically distributed mounting seats 10 are fixed to one side wall of the frame body b 9. One side wall of each two mounting seats 10 is jointly rotatably connected to a guide roller a 11.

[0031] Further, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, it is worth specifically explaining that the positioning component 6 includes a bearing plate 61 which is fixed to one side wall of the frame 1. A mounting plate 62 is slidably connected to the inner side of the bearing plate 61. A threaded rod a63 is threadedly connected to one side wall of the mounting plate 62. A runner 64 is fixed to one end of the threaded rod a63. The other end of the threaded rod a63 is rotatably connected to a sleeve 65. One end of the sleeve 65 is in contact with one side of the winding roller 5; a limiting rod 66 is slidably penetrated through one side wall of the mounting plate 62. A pull ring 67 is fixed to one end of the limiting rod 66. A spring 68 is sleeved on the outer surface of the limiting rod 66. One end of the spring 68 is fixed to one side wall of the pull ring 67. The other end of the spring 68 is fixed to one side wall of the mounting plate 62. A plurality of equally spaced limiting holes 69 are formed in one side wall of the bearing plate 61. The limiting rod 66 is adapted to the limiting holes 69. Through the setting of the positioning component 6, the winding roller 5 can be effectively positioned, so as to facilitate the staff to disassemble and assemble the winding roller 5 for use, which is beneficial for the staff to replace the winding roller 5 to wind the cable. Moreover, the positioning and installation effect of the winding roller 5 is good, which can avoid the situation of jamming when the winding roller 5 is running. It has good practicability, flexible and convenient operation, and strong structural reliability.

[0032] Further, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, it is worth specifically explaining that the wire guiding component 8 includes a guide groove 81 which is fixed to the inner side wall of the frame a7. A reciprocating lead screw 82 is rotatably connected to one side wall of the frame a7. A nut 83 is threadedly connected to the external thread of the reciprocating lead screw 82. The nut 83 is slidably connected to the inside of the guide groove 81. A bracket 84 is fixed to the top side wall of the nut 83. A guide wheel 85 is rotatably connected to one side wall of the bracket 84. A belt pulley 86 is fixed between the reciprocating lead screw 82 and the shaft body 3. A belt 87 is sleeved on the outer surfaces of the two belt pulleys 86. A support frame 88 is fixed to one side wall of the frame a7. A driving motor 89 is fixed to the top side wall of the support frame 88. One end of the output shaft of the driving motor 89 is coaxially fixed to one end of the reciprocating lead screw 82. Through the setting of the wire guiding component 8, the cable can be driven to reciprocally traction and move, so as to ensure that the cable is evenly wound around the outer surface of the winding roller 5, prevent the situation of mess or even jamming when winding the cable, and has good stability and smoothness for the cable winding work. Moreover, the working efficiency of the cable winding work is effectively improved.

[0033] This solution has the following working process: When technicians use this device, first, the winding roller 5 is sleeved on the surface of the shaft body 3. By pulling the pull ring 67, the limiting rod 66 moves after being stressed until it separates from the limiting hole 69, thus releasing the limiting state of the additional mounting plate 62. Then, the additional mounting plate 62 can be pushed to the appropriate position. By loosening the pull ring 67, due to the elastic action of the spring 68, the limiting rod 66 engages with the limiting hole 69 to complete the limiting of the additional mounting plate 62. By rotating the rotating wheel 64, the threaded rod a63 rotates synchronously, driving the sleeve 65 to move synchronously until the sleeve 65 is in contact with the winding roller 5, thus completing the positioning of the winding roller 5. When it is necessary to adjust the tension during cable winding, driven by the servo motor 128, the threaded rod b125 rotates synchronously. Using the threaded transmission between the threaded rod b125 and the threaded sleeve 126, the guide roller b123 moves after being stressed, so as to achieve the purpose of adjusting the tension of the cable during winding. Driven by the driving motor 89, the reciprocating lead screw 82 rotates synchronously. Using the threaded transmission between the reciprocating lead screw 82 and the lead screw sleeve 83, the lead screw sleeve 83 moves along the guide groove 81 after being stressed, thus driving the guide wheel 85 to move reciprocally. Using the transmission of the belt pulley 86 and the belt 87, the shaft body 3 rotates synchronously, driving the winding roller 5 to rotate synchronously, causing the cable to be evenly wound around the outer surface of the winding roller 5 to complete the winding of the cable.

[0034] According to the above working process, it can be seen that: Through the setting of the positioning component 6, the winding roller 5 can be effectively positioned, which is convenient for the staff to disassemble and assemble the winding roller 5 for use, facilitating the staff to replace the winding roller 5 for cable winding operations. Moreover, the positioning and installation effect of the winding roller 5 is good, which can avoid the situation of the winding roller 5 getting stuck during operation, having good practicability, flexible and convenient operation, and strong structural reliability. And through the setting of the wire guiding component 8, the cable can be driven to move reciprocally and tractionally, thus ensuring that the cable is evenly wound around the outer surface of the winding roller 5, preventing the cable from becoming messy or even getting stuck during winding. For the cable winding work, it has good stability and smoothness, and effectively improves the working efficiency of the cable winding work. And through the setting of the tension component 12, the tension of the cable during winding can be adjusted according to actual needs, effectively improving the stability during cable winding, avoiding the situation of messy rework due to insufficient tension during cable winding. For the cable winding work, it has good qualified guarantee, thus facilitating the adjustment of the tension of the cable to achieve the purpose of conveniently adjusting the cable tension.

[0035] Furthermore, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、Figure 5 and Figure 6 As shown in Figure 6 , it is worth specifically stating that a tension assembly 12 is provided on one side of the frame body b9. The tension assembly 12 includes two sliding grooves 121 which are symmetrically distributed and opened on the side wall of one side of the frame body b9. A slider 122 is slidably connected inside each of the two sliding grooves 121. A guide roller b123 is rotatably connected to the adjacent side walls of the two sliders 122. Two symmetrically distributed bearing seats 124 are fixed on the side wall of one side of the frame body b9. A threaded rod b125 is rotatably connected to the adjacent side walls of the two bearing seats 124. A threaded sleeve 126 is threadedly connected to the external thread of the threaded rod b125. One side wall of the threaded sleeve 126 is fixed to one side wall of one of the sliders 122. A base plate 127 is fixed on the top side wall of the frame body b9. A servo motor 128 is fixed on one side wall of the base plate 127. One end of the output shaft of the servo motor 128 is coaxially fixed to one end of the threaded rod b125. Through the setting of the tension assembly 12, the tension of the cable during winding can be adjusted according to actual needs, effectively improving the stability during the winding of the cable, and avoiding the situation of messy rework due to insufficient tension during the winding of the cable. For the cable winding work, it has good qualified guarantee, thus facilitating the adjustment of the tension of the cable and achieving the purpose of conveniently adjusting the cable tension.

[0036] Furthermore, as shown in Figure 1 and Figure 6 As shown in Figure 6 , it is worth specifically stating that the cross-sections of the two guide rollers a11 are located on the same horizontal plane, and the length value of the threaded rod b125 is greater than the opening length value of the sliding groove 121. Through the setting of the threaded rod b125 and the sliding groove 121, the situation that the threaded rod b125 is disconnected from the sliding groove 121 due to excessive transmission distance between the threaded rod b125 and the threaded sleeve 126 can be avoided.

[0037] Furthermore, as shown in Figure 1 and Figure 2 As shown in Figure 2 , it is worth specifically stating that two symmetrically distributed reinforcing rods 13 are fixed on the bottom side wall of the bearing plate 61. One end of the reinforcing rod 13 away from the bearing plate 61 is fixed to the side wall of one side of the frame 1. Through the setting of the reinforcing rod 13, the load-bearing capacity of the bearing plate 61 can be greatly improved, and the stability of the additional plate 62 during movement can be effectively improved.

[0038] Furthermore, as shown in Figure 1 and Figure 6 As shown in Figure 6 , it is worth specifically stating that the cross-section of the sleeve 65 is concave-shaped, and the central axis of the sleeve 65 is collinear with the central axis of the shaft body 3. Through the setting of the sleeve 65, the stability of the winding roller 5 sleeved on the surface of the shaft body 3 can be ensured, and the situation that the winding roller 5 gets stuck during operation can be effectively prevented.

[0039] In summary: Through the settings of the threaded rod b125 and the chute 121, it is possible to avoid the situation where the threaded rod b125 is disengaged from the chute 121 due to excessive transmission distance between the threaded rod b125 and the threaded sleeve 126. And through the setting of the reinforcing rod 13, the load-bearing capacity of the bearing plate 61 can be greatly improved, effectively improving the stability of the additional plate 62 during movement. And through the setting of the sleeve 65, the stability of the winding roller 5 sleeved on the surface of the shaft body 3 can be ensured, effectively preventing the winding roller 5 from jamming during operation.

[0040] Both the drive motor 89 and the servo motor 128 can be purchased on the market. The drive motor 89 and the servo motor 128 are both equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
