[0017] (3) Beneficial effects:

[0018] A. The automatic coating assembly in the overhead bare wire automatic coating device is arranged such that the bare wire passes through the rotating tubes on both sides of the coating box, and the bare wire passes through the rubber ball. The compressed air generated by the control air pump is input into the first turbine pump through the air supply pipe and discharged through the air outlet elbow. The circulation of compressed air drives the first turbine pump, which drives the half gear to rotate through the transmission shaft. The cooperation of the half gear teeth and the tooth grooves drives the lifting rod to lift and lower reciprocately. The pressure roller at the bottom of the lifting rod reciprocates and squeezes the rubber ball. The reciprocating deformation of the rubber ball can suck the coating in the coating box through the rotating tube and the suction tube. The coating enters the rubber ball to coat the bare wire passing through. During the extrusion of the rubber ball, the coating sucked in the rubber ball is sprayed into the rotating tube. The coating in the rotating tube can be fully and effectively coated on the outer wall of the bare wire. The compressed air discharged from the air outlet elbow is blown out at the first blowing hood, which plays the role of blowing and drying the bare wire after the coating process, which is beneficial to the condensation of the coating on the bare wire.

[0019] B. During the automatic coating process of the bare wire passing through the rubber ball, the rotation of the air pump will drive the first pulley to rotate through the installation shaft, and the coordinated transmission of the belt will drive the second pulley and the rotating tube to rotate, thereby driving the rubber ball to rotate in the inner ball groove, so that the rubber ball can stir the paint in the inner ball groove to avoid the occurrence of paint condensation problems. The rotating rubber ball and rotating tube disturb the paint sucked inside, so that the paint is evenly coated on the outer wall of the conveyed bare wire. During the rotation of the rotating tube, the internal paint brush will fully brush the outer wall of the conveyed bare wire, thereby improving the efficiency and effect of automatic coating of the bare wire.

[0020] C. Through the setting of the pressing and grinding component, during the conveying of the bare wire in the guide groove at the top of the wire holder, the overhead wire feeding roller will synchronously drive the second turbine pump to work during its operation, and the generated compressed air is input into the end tube through the air injection pipe. The pressure increase in the end tube drives the piston and the connecting rod to move downward, thereby driving the connecting frame and the grinding roller to move downward. The grinding roller is pressed on the bare wire on the guide groove. During the conveying of the bare wire, the grinding roller rotates to grind the outer wall of the bare wire, which is beneficial to the subsequent coating of the bare wire. When the pressure in the end tube reaches the threshold of the pressure relief valve, the excess air is discharged through the exhaust elbow and the second blowing hood, and the bare wire conveyed after grinding is blown to dust, and the grinding chips on the outer wall of the bare wire are blown off, which is beneficial to the subsequent coating of the bare wire. The second turbine pump works by suctioning inside the wire holder through the suction pipe, so that the waste chips generated by the grinding of the bare wire are sucked into the inside of the wire holder through the filter, thereby realizing the function of collecting the waste chips generated by the grinding of the bare wire.

A tooth groove 612 is opened on the outer wall of one side of the lifting rod 605, and the half gear 611 is meshed with the tooth groove 612. An air pump 613 is installed on the top outer wall of the paint box 5, and the air delivery end of the air pump 613 is connected to the air delivery pipe 614.

During the overhead conveying process of the bare wire of the overhead bare wire automatic coating device, the bare wire passes through the rotating tubes 603 on both sides of the coating box 5, so that the bare wire passes through the rubber ball 602. During the coating process, the air pump 613 is controlled to work, and the generated compressed air is input into the first turbine pump 615 through the air delivery pipe 614 and discharged through the air outlet elbow 616. The compressed air circulates in the first turbine pump 615 to drive the first turbine pump 615, thereby driving the half gear 611 to rotate through the transmission shaft 610.

It will drive the second pulley 10 and the rotating tube 603 to rotate, thereby driving the rubber ball 602 to rotate in the inner ball groove 601, so that the rubber ball 602 can stir the paint in the inner ball groove 601 to avoid the occurrence of paint condensation problems. The rotating rubber ball 602 and the rotating tube 603 disturb the internally sucked paint, so that the paint is evenly coated on the outer wall of the conveyed bare wire. During the rotation of the rotating tube 603, the internal paint brush 12 will fully brush the outer wall of the conveyed bare wire, thereby improving the efficiency and effect of automatic coating of the bare wire.

[0037] Furthermore, a bearing 19 is embedded in the rotating connection between the rotating tube 603 and the paint box 5, and oil seals are installed on the inner walls of the paint box 5 on both sides of the bearing 19, so that the rotating tube 603 rotates more smoothly, and the oil seals prevent the paint in the paint box 5 from flowing out.

[0042] Beneficial effects of the present invention: The automatic coating assembly 6 in the overhead bare wire automatic coating device is set up, the bare wire passes through the rotating tubes 603 on both sides of the coating box 5, and the bare wire passes through the rubber ball 602. The compressed air generated by the control air pump 613 is input into the first turbine pump 615 through the air pipe 614 and discharged through the air outlet elbow 616. The compressed air circulates in the first turbine pump 615 to drive the first turbine pump 615, thereby driving the half gear 611 to rotate through the transmission shaft 610, and the cooperation of the tooth portion of the half gear 611 and the tooth groove 612 will drive the lifting rod 605 to reciprocate and lift, and the bottom of the lifting rod 605 The pressure roller 606 will reciprocately squeeze the rubber ball 602 in the paint box 5. The reciprocating deformation of the rubber ball 602 can suck the paint in the paint box 5 through the rotating tube 603 and the suction tube 618. The paint enters the rubber ball 602 to coat the bare wire passing through. During the squeezing process of the rubber ball 602, the paint sucked in the rubber ball 602 is sprayed into the rotating tube 603. The paint in the rotating tube 603 can be fully and effectively coated on the outer wall of the bare wire. The compressed air discharged from the air outlet elbow 616 is blown out at the first blowing hood 617, which plays the role of blowing and drying the bare wire after the coating process, which is beneficial to the condensation of the paint coated on the bare wire.

[0043] Furthermore, during the process of automatic coating of the bare wire passing through the rubber ball 602, the rotation of the air pump 613 will drive the first pulley 9 to rotate through the installation shaft 8, and the coordinated transmission of the belt 11 will drive the second pulley 10 and the rotating tube 603 to rotate, thereby driving the rubber ball 602 to rotate in the inner ball groove 601, so that the rubber ball 602 can stir the paint in the inner ball groove 601 to avoid the occurrence of paint condensation problems.

The pressure rise in the end tube 702 drives the piston 703 and the connecting rod 704 to move downward, thereby driving the connecting frame 706 and the grinding roller 707 to move downward. The grinding roller 707 is pressed on the bare wire on the guide groove 13. During the bare wire conveying process, the grinding roller 707 rotates to press the bare wire. The outer wall of the conductor is polished to facilitate the subsequent coating of the bare conductor. When the pressure in the end tube 702 reaches the threshold of the pressure relief valve 712, excess air is discharged through the exhaust elbow 711 and the second blowing hood 713, and the bare conductor transported after polishing is blown to dust, and the polishing chips on the outer wall of the bare conductor are blown off, which is beneficial to the subsequent coating of the bare conductor. The second turbine pump 708 works by suctioning inside the conductor holder 4 through the suction pipe 15, so that the waste chips generated by the polishing of the bare conductor are sucked into the inside of the conductor holder 4 through the filter 14, thereby realizing the function of collecting the waste chips from the polishing of the bare conductor.

During the operation of the overhead wire feeding roller 2, the second turbine pump 708 is driven to work synchronously. The generated compressed air is input into the end tube 702 through the air injection pipe 709. The pressure rises in the end tube 702, driving the piston 703 and the connecting rod 704 to move downward, thereby driving the connecting frame 706 and the grinding roller 707 to move downward. The grinding roller 707 is pressed on the bare wire on the guide groove 13. During the bare wire conveying process, the grinding roller 707 rotates to grind the outer wall of the bare wire, which is beneficial to the later bare wire. During the coating of the wire, when the pressure in the end tube 702 reaches the threshold of the pressure relief valve 712, the excess air is discharged through the exhaust elbow 711 and the second blowing hood 713, and the bare wire transported after grinding is blown to blow dust, and the grinding chips on the outer wall of the bare wire are blown off, which is beneficial to the subsequent coating of the bare wire. The second turbine pump 708 works to suck inside the wire holder 4 through the suction pipe 15, so that the waste chips generated by the grinding of the bare wire are sucked into the inside of the wire holder 4 through the filter screen 14, so as to collect the grinding waste chips of the bare wire. During the overhead transportation of the bare wire, the bare wire passes through the rotating tubes 603 on both sides of the coating box 5, so that the bare wire passes through the rubber ball 602. During the coating process, the air pump 613 is controlled to work, and the compressed air generated is input to the The compressed air is discharged from the first turbine pump 615 through the air outlet elbow 616. The compressed air circulates in the first turbine pump 615 to drive the first turbine pump 615, thereby driving the half gear 611 to rotate through the transmission shaft 610. During the transmission process, the teeth of the half gear 611 and the tooth groove 612 drive the lifting rod 605 to move downward along the bobbin 604. During the process, the limit block 607 moves downward to compress the first spring 608. When the toothless part of the half gear 611 rotates to the tooth groove 612, the lifting rod 605 is driven to reset and move upward under the action of the first spring 608. The continuous rotation of the half gear 611 causes the lifting rod 605 to reciprocate and lift. The pressure roller 606 at the bottom of the lifting rod 605 reciprocates and squeezes the rubber ball 602 in the paint box 5. The reciprocating deformation of the rubber ball 602 can suck the paint in the paint box 5 through the rotating tube 603 and the suction tube 618, and the paint enters the rubber ball 602 to coat the bare wire passing through. During the extrusion process of the rubber ball 602, the paint sucked in the rubber ball 602 is sprayed into the rotating tube 603. The paint in the rotating tube 603 can be fully and effectively coated on the outer wall of the bare wire. The compressed air discharged from the air outlet elbow 616 is blown out at the first blowing hood 617, which plays the role of blowing and drying the bare wire after the coating process, which is beneficial to the condensation of the paint coated on the bare wire. The rotation of the air pump 613 drives the first pulley 9 to rotate through the installation shaft 8, and the coordinated transmission of the belt 11 drives the second pulley 10 and the rotating tube 603 to rotate.Thus, the rubber ball 602 is driven to rotate in the inner ball groove 601, so that the rubber ball 602 can stir the paint in the inner ball groove 601 to avoid the occurrence of paint condensation. The rotating rubber ball 602 and the rotating tube 603 disturb the internally sucked paint, so that the paint is evenly coated on the outer wall of the conveying bare wire. During the rotation of the rotating tube 603, the internal paint brush 12 will fully brush the outer wall of the conveying bare wire, thereby improving the efficiency and effect of the automatic coating of the bare wire.
