Description

Technical Field

[0001] This application relates to the field of wire and cable production equipment technology, and in particular to a wire and cable winding tension adjustment mechanism. Background Technology

[0002] In the production process of wires and cables, the winding process is one of the key steps. The stability of the winding tension directly affects the winding quality of the cable. If the tension is too small, the cable winding is prone to problems such as loosening and interlayer misalignment; if the tension is too large, it may cause the cable to stretch and deform, damage the insulation layer, and affect the product performance.

[0003] Existing wire and cable winding equipment mostly adopts manual adjustment or simple mechanical tensioning structures. Manual adjustment relies on the operator's experience, has low adjustment accuracy, and cannot respond to tension changes in real time. Mechanical tensioning structures usually provide fixed tension through springs or counterweights, which is difficult to dynamically adjust according to changes in cable specifications or winding speed, resulting in poor adaptability. For example, when the cable diameter increases, the linear speed of the winding roller will change with the radius. If the tension is not adjusted in time, it will easily lead to tension fluctuations, affecting the winding quality. Therefore, a wire and cable winding tension adjustment mechanism is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a wire and cable winding tension adjustment mechanism to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this application for a wire and cable winding tension adjustment mechanism is as follows:

[0006] A wire and cable winding tension adjustment mechanism includes a base plate, a base fixedly connected to the top outer wall of the base plate, a winding roller provided on the outer wall of the base, and a tension adjustment assembly installed on the top outer wall of the base plate.

[0007] The tension adjustment assembly includes a lifting plate, connecting rods, a bidirectional lead screw, screw blocks, and a cable guide wheel. The two ends of the bidirectional lead screw are rotatably connected to the top outer wall of the base plate through a bearing seat. The two screw blocks are symmetrically threaded to the outer wall of the bidirectional lead screw. The bottom ends of the two connecting rods are rotatably connected to the top outer wall of the two screw blocks, and their top ends are rotatably connected to the bottom outer wall of the lifting plate.

[0008] The top outer wall of the lifting plate is rotatably connected to a reciprocating lead screw via two mounting seats, and a cable guide wheel is threaded onto the outer wall of the reciprocating lead screw.

[0009] Preferably, two pressure sensors are installed between the lifting plate and the two mounting seats. The fixed ends of the two pressure sensors are fixedly connected to the top outer wall of the lifting plate, and their force-bearing ends are fixedly connected to the bottom of the two mounting seats respectively.

[0010] Preferably, two limiting slide rods are fixedly connected to the outer walls of the two mounting seats opposite each other, and the two limiting slide rods pass through the cable guide wheel and are slidably connected to it.

[0011] Preferably, a stepper motor is fixedly mounted on the outer wall of one of the mounting bases, and the end of the output shaft of the stepper motor passes through the mounting base and is fixedly connected to one end of a reciprocating lead screw.

[0012] Preferably, a servo motor is fixedly installed on the top outer wall of the base plate, and the end of the output shaft of the servo motor is fixedly connected to one end of a bidirectional lead screw.

[0013] Preferably, the top outer wall of the base plate is fixedly connected with a plurality of telescopic columns, the telescopic ends of the plurality of telescopic columns are fixedly connected to the bottom outer wall of the lifting plate, and the plurality of telescopic columns are evenly distributed at the four corner edges of the lifting plate.

[0014] Preferably, the outer wall of the base is rotatably connected to a mounting plate, the take-up roller is detachably mounted on the outer wall of the mounting plate, and a secondary gear is fixedly connected to the outer wall of the mounting plate on the side opposite to the take-up roller.

[0015] Preferably, a winding motor is fixedly installed on the outer wall of the base, and the output shaft of the winding motor passes through the base and is fixedly connected to a main gear, which meshes with a secondary gear.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] This mechanism uses a tension detection component to capture tension-related signals in real time during the cable winding process and transmits these signals to the drive component. The drive component dynamically adjusts the tension adjustment assembly based on the signals, achieving automated and precise adjustment of the winding tension. This eliminates the need for operator experience and avoids the drawbacks of low precision and inability to respond to tension changes in manual adjustment. It also abandons the traditional mechanical tensioning structure that relies on springs or counterweights to provide fixed tension. The tension can be flexibly adjusted according to different cable specifications or the changes in the winding roller's linear speed with radius during winding, greatly improving equipment adaptability. This effectively prevents problems such as loose cable winding and interlayer misalignment due to insufficient tension, or cable stretching deformation and insulation damage due to excessive tension. It significantly improves cable winding quality and product performance. Furthermore, the overall structure of the mechanism is stable, and the cable arrangement component can cooperate to achieve uniform cable distribution, further ensuring winding effect, reducing equipment failure rate, and improving production efficiency.

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0023] This application discloses a wire and cable winding tension adjustment mechanism. (Refer to...) Figure 1-3 A wire and cable winding tension adjustment mechanism includes a base plate 1, which serves as the basic support for the entire mechanism and is placed on a horizontal working surface. The top outer wall of the base plate 1 is fixedly connected to a base 2 by welding. The base 2 is vertically arranged and is used to support winding-related components. The top outer wall of the base plate 1 is also fixedly installed with tension adjustment components by bolts, providing an installation foundation for the tension adjustment function.

[0024] The outer wall of the base 2 is rotatably connected to the mounting plate 3 via a bearing. The inner ring of the bearing is interference-fitted with the shaft section of the mounting plate 3, and the outer ring is interference-fitted with the mounting hole of the base 2, ensuring that the mounting plate 3 can rotate stably around its own axis. The take-up roller 4 is detachably mounted on the outer wall of the mounting plate 3 by bolts. The bolts pass through the flange hole of the take-up roller 4 and connect to the threaded hole of the mounting plate 3, which facilitates the replacement of different specifications of the take-up roller 4 according to the cable winding length requirements. The outer wall of the mounting plate 3 on the side opposite to the take-up roller 4 is fixed with a key. The secondary gear 6 is coaxially set with the mounting plate 3, and the two rotate synchronously.

[0025] The outer wall of the base 2 is fixedly mounted with a winding motor 5 by bolts. The output shaft axis of the winding motor 5 is perpendicular to the axis of the mounting plate 3. After the end of the output shaft of the winding motor 5 passes through the through hole of the base 2, the main gear 7 is fixed by a key. The main gear 7 meshes with the secondary gear 6 to form a transmission engagement. When the winding motor 5 is working, it can drive the mounting plate 3 and the winding roller 4 to rotate synchronously through the meshing of the main gear 7 and the secondary gear 6, thereby realizing the cable winding action.

[0026] The tension adjustment assembly includes a lifting plate 9, a connecting rod 15, a double-acting lead screw 16, screw blocks 17, and a cable guide wheel 19. The two ends of the double-acting lead screw 16 are rotatably connected to the top outer wall of the base plate 1 via bearing seats. The bearing seats are fixed to the base plate 1 by bolts. The shaft section of the double-acting lead screw 16 is interference-fitted with the inner ring of the bearing seat to ensure that the double-acting lead screw 16 can rotate stably around its own axis. The two screw blocks 17 are symmetrically threaded to the outer wall of the double-acting lead screw 16. The two sections of the threads on the outer wall of the double-acting lead screw 16 have opposite directions of rotation. When the double-acting lead screw 16 rotates, the two screw blocks 17 can synchronously move closer or further away along the axis of the double-acting lead screw 16.

[0027] The bottom ends of the two connecting rods 15 are rotatably connected to the top outer wall of the two screw blocks 17 via pins, and the top ends of the connecting rods 15 are rotatably connected to the bottom outer wall of the lifting plate 9 via pins, forming a scissor support structure. When the two screw blocks 17 move along the bidirectional screw 16, the lifting plate 9 can be pushed or pulled vertically by the connecting rods 15.

[0028] Multiple telescopic columns 8 are fixedly connected to the top outer wall of the base plate 1 by bolts. The multiple telescopic columns 8 are evenly distributed along the circumference of the lifting plate 9 at the four corner edges of the lifting plate 9. The telescopic ends of the telescopic columns 8 are fixedly connected to the bottom outer wall of the lifting plate 9 by bolts. The telescopic columns 8 are perpendicular to the lifting plate 9. When the lifting plate 9 rises and falls, the telescopic columns 8 extend and retract synchronously, which guides and supports the movement of the lifting plate 9 and prevents the lifting plate 9 from tilting or shaking.

[0029] The servo motor 18 is fixedly installed on the top outer wall of the base plate 1 by bolts. The output shaft axis of the servo motor 18 is collinear with the axis of the bidirectional lead screw 16. The end of the output shaft of the servo motor 18 is fixedly connected to one end of the bidirectional lead screw 16 through a coupling. When the servo motor 18 is working, it can directly drive the bidirectional lead screw 16 to rotate, providing power to the bidirectional lead screw 16.

[0030] Two pressure sensors 10 are fixed to the top outer wall of the lifting plate 9 by bolts. The force-bearing ends of the two pressure sensors 10 are fixed to the mounting base 11 by bolts. That is, the mounting base 11 is indirectly installed on the lifting plate 9 through the pressure sensors 10. The pressure sensors 10 can detect the pressure signal transmitted by the mounting base 11 in real time. This pressure signal is related to the cable winding tension.

[0031] Two limiting slide rods 14 are bolted to the outer walls of the two mounting seats 11. The two limiting slide rods 14 are arranged in a direction parallel to the axis of the reciprocating screw 12. The reciprocating screw 12 is rotatably connected between the two mounting seats 11 through a bearing. The shaft of the reciprocating screw 12 is interference-fitted with the inner ring of the bearing of the mounting seat 11 to ensure that the reciprocating screw 12 can rotate stably around its own axis. The wire guide wheel 19 is threaded to the outer wall of the reciprocating screw 12. At the same time, both limiting slide rods 14 pass through the sliding hole of the wire guide wheel 19 and slide with the wire guide wheel 19. The limiting slide rods 14 can restrict the wire guide wheel 19 from rotating with the reciprocating screw 12, so that the wire guide wheel 19 can only move smoothly along the axis of the reciprocating screw 12.

[0032] One of the mounting bases 11 has a stepper motor 13 fixedly mounted on its outer wall by bolts. The output shaft axis of the stepper motor 13 is collinear with the axis of the reciprocating lead screw 12. After the end of the output shaft of the stepper motor 13 passes through the through hole of the corresponding mounting base 11, it is fixedly connected to one end of the reciprocating lead screw 12 through a coupling. When the stepper motor 13 is working, it can drive the reciprocating lead screw 12 to rotate, thereby driving the cable winding wheel 19 to move back and forth along the axis of the reciprocating lead screw 12, so as to achieve uniform cable winding when the cable is wound up.

[0033] The servo motor 18 and the pressure sensor 10 are electrically connected by wires. The pressure sensor 10 can transmit the detected pressure signal to the controller of the servo motor 18. The controller determines the current tension of the cable based on the pressure signal and controls the servo motor 18 to adjust its speed and direction, thereby adjusting the rotation state of the bidirectional lead screw 16, realizing the dynamic adjustment of the height of the lifting plate 9, and ultimately achieving the purpose of adjusting the cable tension.

[0034] The implementation principle of the cable winding tension adjustment mechanism in this application embodiment is as follows: Before the equipment is started, one end of the cable to be wound is fixed on the outer wall of the winding roller 4. The cable passes through the groove of the wire feeding wheel 19 in sequence to complete the wire threading operation. The tension threshold required for cable winding is preset by the controller of the servo motor 18 to determine the target detection range of the pressure sensor 10.

[0035] Start the winding motor 5. The winding motor 5 drives the mounting plate 3 and the winding roller 4 to rotate through the meshing transmission of the main gear 7 and the auxiliary gear 6. The winding roller 4 begins to wind up the cable. At the same time, start the stepper motor 13. The stepper motor 13 drives the reciprocating screw 12 to rotate. Under the guidance of the limit slide rod 14, the cable tray 19 moves back and forth along the axis of the reciprocating screw 12, evenly distributing the cable on the outer wall of the winding roller 4.

[0036] During the winding process, the cable generates tension on the cable guide wheel 19. This tension is transmitted through the cable guide wheel 19 and the reciprocating lead screw 12 to the mounting base 11, and then from the mounting base 11 to the pressure sensor 10. The pressure sensor 10 detects the pressure signal in real time and transmits it to the controller of the servo motor 18.

[0037] If the detected pressure value is greater than the preset threshold, it indicates that the cable tension is too high. The controller controls the servo motor 18 to rotate in the forward direction, driving the bidirectional lead screw 16 to rotate, so that the two screw blocks 17 move closer along the bidirectional lead screw 16. Through the connecting rod 15, the lifting plate 9 is pushed up, and the cable guide wheel 19 rises with the lifting plate 9. The cable winding path is shortened, and the tension is reduced until the pressure value returns to the preset threshold range.

[0038] If the detected pressure value is less than the preset threshold, it indicates that the cable tension is too low. The controller controls the servo motor 18 to rotate in the opposite direction, driving the bidirectional lead screw 16 to rotate in the opposite direction, so that the two screw blocks 17 move away from the bidirectional lead screw 16. The lifting plate 9 is pulled down through the connecting rod 15, and the cable guide wheel 19 descends with the lifting plate 9. The cable winding path is extended, and the tension increases accordingly until the pressure value returns to the preset threshold range.

[0039] When the cable on the take-up roller 4 reaches the preset take-up length, turn off the take-up motor 5 and the stepper motor 13, loosen the bolts connecting the take-up roller 4 and the mounting plate 3, remove the take-up roller 4 and the cable, and complete one take-up operation. If you need to replace the cable with a different specification, you only need to replace the take-up roller 4 with the corresponding specification and adjust the preset tension threshold through the controller.
