When winding with the existing winding device, the tension value of the tape in the device is constant after being set. However, after increasing the rotation speed during the operation of the device, due to the increase in the wind speed in the winding cage, irregular eddies will be generated, which will affect the winding of the tape, and then problems such as unstable tape tension and decreased SI performance of the wire pair will occur.

[0016] Embodiment

[0017] To solve the above technical problems, this embodiment provides an automatic tension-adjusting wrapping machine, as Figure 1 shown, which includes a frame 10 and a wrapping head 20. A docking support wheel assembly 30 for guiding and pressing the wire is further provided at the output end of the frame 10 where the wrapping head 20 is located. A detection component 21 for detecting the wind speed is provided on the wrapping head 20. The detection component 21 is communicatively connected to the control system. The detection component 21 can be a resistive, thermal, or ultrasonic wind speed sensor. By providing the detection component 21 on the wrapping head 20, when the wrapping head 20 wraps the wire, the wrapping tension of the wrapping head 20 can be adjusted according to the feedback of the detection component 21, thereby ensuring the physical properties and wrapping tension stability of the wire product. Then, by providing the docking support wheel assembly 30 at the output end of the wrapping head 20, after the wire is wrapped by the wrapping head 20, the wrapping layer wrapped on the surface of the wire is pressed and guided out by the docking support wheel assembly 30, realizing the monitoring of the wind speed of the wrapping head 20 to cooperate with the adjustment of the wrapping tension of the wire and ensuring the physical properties of the wire product.

[0018] In this embodiment, the wrapping head 20 can adjust the wrapping tension according to the feedback result of the detection component 21. The calculation formula for the actually required wrapping tension can be as follows:

[0019] F2 = F1 - f × b × v, where F2 is the actually applied tension value, F1 is the set tension value, f is the correction coefficient, b is the tape width, and v is the wind speed.

[0020] Specifically, as Figure 2 shown, a driving component 40 is further provided on the side of the frame 10 away from the docking support wheel assembly 30 where the wrapping head 20 is located. The driving end of the driving component 40 is connected to the wrapping head 20. By providing the driving component 40 on the frame 10 and connecting the driving end of the driving component 40 to the wrapping head 20, the driving component 40 can drive the wrapping head 20 to tension-wrap the wire, realizing the driving of the wrapping head 20 to perform the wrapping process.

[0021] In the above solution, the driving component 40 and the wrapping head 20 are electrically connected to the control system. By setting, the driving component 40 and the wrapping head 20 are electrically connected to the control system. Then, when the wire is being wrapped, the control system can monitor the wind speed in the wrapping head 20 through the detection component 21. When the wind speed reaches the critical value that affects the wrapping tension, the control system can adjust the corresponding required wrapping tension for the wrapping head 20 to ensure relatively stable wrapping tension, and gradually increase the rotation speed of the driving component 40 to improve the working efficiency of the wrapping head 20, realizing the adjustment of the driving component 40 and the wrapping head 20 according to the feedback of the detection component 21 to ensure stable wrapping tension of the wire.

[0022] Further, the butt pulley assembly 30 includes a guiding chute 31 provided on the frame 10. A connecting frame 32 is slidably arranged on the guiding chute 31. A butt pulley 33 for guiding and pressing the wire is arranged on one side of the connecting frame 32 close to the wrapping head 20. By providing a guiding chute 31 on the frame 10, a connecting frame 32 is slidably arranged on the guiding chute 31, and the connecting frame 32 is fixedly provided with a butt pulley 33. After the wire is wrapped, by connecting one end to the butt pulley 33, the wrapping layer on the surface of the wire is pressed and fixed by the butt pulley 33. Then, by sliding the connecting frame 32 on the guiding chute 31, the connecting frame 32 can be horizontally adjusted according to the guiding chute 31, further cooperating with the butt pulley 33 to press the wire, realizing guiding and outputting the wrapped wire and further pressing and fixing the wrapping layer on the surface of the wire.

[0023] In order to press and export the wire, as a preferred embodiment, a fixing frame 22 is further arranged on one side of the wrapping head 20 close to the butt pulley assembly 30. A through groove 221 for the wire and the butt pulley 33 to pass through is opened on the fixing frame 22. The detection component 21 is fixedly arranged on the fixing frame 22. By arranging a fixing frame 22 on one side of the wrapping head 20, opening a through groove 221 on the fixing frame 22, and fixedly arranging the detection component 21 on the fixing frame 22, the butt pulley 33 can press and fix the wire through the through groove 221. Then, by fixedly arranging the detection component 21 on the fixing frame 22, during the wrapping process of the wrapping head 20, the detection component 21 can monitor the wind speed of the wrapping head 20, realizing the cooperation with the butt pulley 33 to press and fix the wrapping layer of the wire.

[0024] Specifically, the butt pulley assembly 30 further includes an adjusting block 34. The connecting frame 32 is adjustably connected to the guiding chute 31 through the adjusting block 34. By providing an adjusting block 34 for adjusting the position of the connecting frame 32 relative to the guiding chute, the stroke distance of the connecting frame 32 can be adjusted through the adjusting block 34. Then, the installation position of the adjusting block 34 is adjusted according to the working conditions required for the butt pulley 33 to press the wire, realizing the adjustable installation position of the connecting frame to cooperate with the butt pulley 33 to press the wrapping layer of the wire.

[0025] In the above solution, the docking carrier roller 33 further includes a fixing block connected to the connecting frame 32. A plurality of pressing wheels for guiding and pressing down the wire are hinged on the fixing block. An elastic member for cooperating with the pressing wheels to tightly press the wire is also arranged on the opposite surfaces of the pressing wheels. By providing the fixing block and hinging a plurality of pressing wheels on the fixing block, the wire wound with the wrapping layer in the wrapping head 20 can be tightly pressed and led out through the pressing wheels. Then, by providing the elastic member, when pressing the wire, the elastic member acts on the pressing wheels hinged on the fixing block, making the contact between the pressing wheels and the wire closer, improving the effect of tightly pressing the wrapping layer, and ensuring that the pressing wheels press the wire tightly.

[0026] Further, a pressing wheel groove is formed on the pressing wheel, and the size of the pressing wheel groove matches that of the wire. By forming the pressing wheel groove on the pressing wheel, when the pressing wheel presses the wire, the wire can be tightly fitted into the pressing wheel through the pressing wheel groove, thereby tightly pressing the wire wrapping layer, realizing guiding and fixing the wire on the pressing wheel, and cooperating with the pressing wheel to press and output the wire.

[0027] Specifically, the fixing block is detachably connected to the lifting platform through fasteners. By using fasteners to detachably install the fixing block on the lifting platform, when the pressing wheel is damaged or needs regular maintenance, it is convenient for the staff to quickly disassemble the fixing block and repair or maintain the pressing wheels installed on the fixing block, realizing that the fixing block is detachably connected to the lifting platform for convenient subsequent device replacement and maintenance.

[0028] In summary, in one or more embodiments of the present application, the present application further provides a docking carrier roller assembly for guiding and pressing the wire at the output end of the rack where the wrapping head is located. A detection component for detecting the wind speed is arranged on the wrapping head. The detection component is communicatively connected to the control system. The detection component can be a resistive, thermal or ultrasonic wind speed sensor. By arranging the wrapping head on the rack and the detection component on the wrapping head, when the wrapping head wraps the wire, the wrapping tension of the wrapping head can be adjusted according to the feedback of the detection component, thereby ensuring the physical properties and the stability of the wrapping tension of the wire product. Then, by arranging the docking carrier roller assembly at the output end of the wrapping head, after the wire is wrapped by the wrapping head, the wrapping layer wrapped on the surface of the wire is tightly pressed and guided out through the docking carrier roller assembly, realizing monitoring the wind speed of the wrapping head to cooperate with adjusting the wrapping tension of the wire and ensuring the physical properties of the wire product.
