[0002] In the cable production process, especially when plastics and rubber are used as insulation and sheathing materials, a large amount of static charge is generated during the melting, extrusion, cooling, traction, and winding of raw materials in the extruder. This is due to the high-speed friction, contact, and separation between solid materials and between materials and the metal surfaces of equipment. If this is not effectively controlled and eliminated, it will seriously affect product quality, production efficiency, and operational safety.
[0003] Static electricity in the insulation or sheath surface strongly attracts dust, fibers, and impurities from the air, causing defects on the cable surface and affecting its appearance and performance. Since equipment heights vary during production, and most equipment has a fixed height, additional equipment is needed to adjust the air knife. Therefore, we propose a static electricity elimination and protection device for cable production to address these problems. Utility Model Content

[0023] The fixed ring seat 5 on the right side of the annular air knife 8 is sleeved on the outside of the mounting column 4. The auxiliary connecting rod 7 on the right side of the connecting seat 3 installed at the upper and lower ends of the annular air knife 8 is inserted into the rear end of the mounting column 4. The adjusting seat sleeve 14 is threaded on the adjusting screw 15 at the top of the mounting seat 6. The adjusting seat sleeve 14 drives the mounting column 4 to extend and retract outside the adjusting screw 15.
[0024] Specifically, such as Figure 1 and Figure 2 As shown, by setting up an air knife adjustment structure, during use, the adjustment screw 15 is fixed to the top of the operating table 10 through the mounting seat 6. Then, the annular air knife 8 is sleeved on the outside of the mounting column 4 through the fixing ring seat 5. The auxiliary connecting rod 7 on the right side of the connecting seat 3 is inserted into the rear end of the mounting column 4 and locked. By rotating the adjustment seat sleeve 14 outside the adjustment screw 15, the mounting column 4 is driven to rise and fall outside the adjustment screw 15, so that the mounting column 4 drives the annular air knife 8 to adjust its height, thereby realizing the air knife adjustment function.
[0025] The bottom of the operating table 10 is connected to a support frame 12. An electrostatic eliminator 13 is installed inside the support frame 12. An electrostatic duct 1 is connected to the left side of the electrostatic eliminator 13. A conveying pipe 2 is connected to the right side of the electrostatic duct 1. A support rod 22 is installed on the left side of the top front end of the operating table 10. A connecting sleeve 21 is installed at the front end of the support rod 22. A voltage measuring pen 20 is installed inside the connecting sleeve 21. A connecting wire 19 is connected to the rear end of the voltage measuring pen 20. A voltmeter 11 is installed on the top of the support frame 12.
[0026] The voltage measuring pen 20 is electrically connected to the voltmeter 11 via the connecting wire 19, and the voltage measuring pen 20 is inserted into the connecting sleeve 21 to fix the front end of the support rod 22;
[0027] Specifically, such as Figure 1 and Figure 3 As shown, by setting up a contact monitoring structure, when in use, the voltage measuring pen 20 is inserted into the connecting sleeve 21 at the front end of the support rod 22, and the detection head of the voltage measuring pen 20 is connected to the cable inside the annular air knife 8 to detect the voltage. The voltage measuring pen 20 transmits the voltage signal to the voltmeter 11 through the connecting wire 19 for easy viewing, thereby realizing the contact monitoring function.
[0028] The top rear end of the control panel 10 is equipped with a rear support column 9, and a telescopic rod column 16 is inserted inside the rear support column 9. A support wheel 18 is installed on the top of the telescopic rod column 16, and side locking knobs 17 are installed on both sides of the top of the rear support column 9.
[0029] The telescopic rod 16 at the bottom of the support wheel 18 is inserted into the top of the rear support column 9. The telescopic rod 16 extends and retracts at the top of the rear support column 9. The support wheel 18 extends and retracts at the top of the rear support column 9 through the telescopic rod 16. The side locking knob 17 is inserted on both sides of the rear support column 9 and contacts the telescopic rod 16 inside the rear support column 9.
[0030] Specifically, such as Figure 1 and Figure 4 As shown, by setting up a support adjustment structure, during use, the telescopic rod 16 at the bottom of the support wheel 18 extends and retracts at the top of the rear support column 9 as the height of the annular air knife 8 increases.

Then, the annular air knife 8 is fitted onto the outside of the mounting column 4 via the fixing ring seat 5. The auxiliary connecting rod 7 on the right side of the connecting seat 3 is inserted into the rear end of the mounting column 4 and locked. Rotating the adjusting seat sleeve 14 outside the adjusting screw 15 causes the mounting column 4 to rise and fall outside the adjusting screw 15, allowing the mounting column 4 to adjust the height of the annular air knife 8. Subsequently, as the annular air knife 8 rises, the telescopic rod 16 at the bottom of the support roller 18 extends to the top of the rear support column 9. After adjusting the height of the support roller 18, insert the side locking knobs 17 on both sides of the rear support column 9 into the rear support column 9 and connect them with the telescopic rod column 16 inside the rear support column 9. Fix the support roller 18 to the top of the rear support column 9 to support the cable. Finally, insert the voltage measuring pen 20 into the connecting sleeve 21 at the front end of the support rod 22, and connect the voltage measuring pen 20 to the cable inside the annular air knife 8 to perform voltage detection. Let the voltage measuring pen 20 transmit the voltage signal to the voltmeter 11 through the connecting wire 19 for easy viewing.
