Description

Technical Field

[0001] This utility model relates to the field of insulator core rod processing technology, and in particular to an insulator core rod adhesive coating device. Background Technology

[0002] The insulator core rod is the core component of transmission line insulators, typically made of epoxy resin-impregnated glass fiber, providing mechanical strength and primary electrical insulation. The adhesive coating (such as silicone rubber or epoxy) serves three key functions: first, it seals the tiny pores on the core rod surface, preventing moisture intrusion that could lead to hydrolytic fracture; second, it bonds the core rod to the metal fittings at both ends (flanges, ball joints), ensuring effective transmission of mechanical loads; and third, the elastic adhesive layer buffers the stress caused by the difference in thermal expansion between the metal and composite materials, improving interfacial stress distribution and enhancing overall weather resistance.

[0003] The existing insulator core rod coating process has two main defects: First, the coating uniformity is poor. Traditional fixed spraying or manual operation makes it difficult to ensure that the thickness of the adhesive layer around the core rod is consistent in both direction, often resulting in local accumulation or missed coating, due to the lack of stable rotation drive and precise nozzle layout. Second, there is serious waste of adhesive and a high risk of pollution. Excess adhesive that drips or splashes cannot be effectively recycled, and the open working environment leads to the direct release of volatile organic compounds, as it lacks an integrated closed circulation system and exhaust gas treatment interface. These defects stem from the low degree of equipment automation and the lack of environmental protection design, which restricts product quality and production cost control. Utility Model Content

The turntable 2 and the turntable 17 correspond to the two ends of the core rod. Under the action of cylinder 5, the height of turntable 2 can be adjusted, which facilitates the adjustment and fixation of the mandrel. In order to improve the fixation effect of the mandrel, anti-slip pads are provided at the contact ends of the two turntables, which can greatly improve the stability of the mandrel during rotation and spraying. A high-elasticity sealing strip is designed on the edge of the door of the spray box 1, and a standard interface is reserved in the non-functional area on the rear side of the spray box 1 to allow users to connect external exhaust pipes and exhaust gas treatment devices (such as activated carbon adsorption towers) as needed in the future to remove and treat the VOCs generated during the spraying process.

[0027] An arc-shaped frame 15 is fixedly connected to one end of the inner side of the spray box 1. A collection box 18 is correspondingly provided at the bottom of the spray box 1. Several through holes 14 are opened through the bottom of the spray box 1. The sprayed glue can be collected in the collection box 18 by setting the through holes 14. Slide grooves 4 are opened at both ends of the bracket 6. Slide rods 8 are fixedly connected inside the slide grooves 4. Slider 3 is slidably connected on the slide rods 8. The two ends of the drive box 7 are fixedly connected to the slider 3. By setting the slide rods 8 and slider 3, the lifting stability of the drive component can be greatly improved. An adjustable pressure valve and a pressure sensor are integrated in the air circuit system of the cylinder 5. The control system presets or automatically adjusts the appropriate clamping pressure according to the diameter of the mandrel and sets an upper limit value to prevent damage to the mandrel.

[0028] A liquid storage tank 13 is installed at one outer end of the collection tank 18. A delivery pipe 9 is installed through the top of the liquid storage tank 13. The other end of the delivery pipe 9 is installed inside the arc-shaped frame 15. Several nozzles 26 are installed at the inner end of the arc-shaped frame 15. A delivery pump 10 is installed in the middle of the delivery pipe 9. A return pipe 12 is installed through one end of the collection tank 18 near the liquid storage tank 13. The other end of the return pipe 12 is installed above the liquid storage tank 13. A return pump 11 is installed in the middle of the return pipe 12. Activating the delivery pump 10 can... The glue inside the storage tank 13 is transported to the inside of the arc frame 15 through the delivery pipe 9 and sprayed outward along the nozzle 26 to complete the glue application on the surface of the mandrel. Excess glue enters the collection box 18 through the through hole 14 and can be reused after being filtered by the filter screen 19, reducing the overall glue application cost. The connection between the nozzle 26 and the delivery pipe 9 inside the arc frame 15 is designed as a standard quick-connect or threaded quick-tight connector. Operators can easily remove individual nozzles for cleaning or replacement by opening the box door 16.

[0029] Mounting plates 20 are fixedly connected to both ends of the inner side of the collection box 18. Filter screens 19 are installed inside the mounting plates 20. A connecting frame 23 is fixedly connected to the upper end of the mounting plates 20. A rod 21 is slidably connected inside the connecting frame 23. A door 16 is provided on the outer side of the collection box 15. A slider 25 is fixedly connected to the lower end of the rod 21. A groove 24 is provided inside the connecting frame 23. A spring 22 is fitted on the rod 21. One end of the spring 22 is fixedly connected to the top of the inner side of the connecting frame 23, and the other end is fixedly connected to the slider 25. The slider 25 is slidably connected inside the groove 24. The filter screen 19 and the mounting plate 20 are all provided with limiting grooves that are compatible with the slider 25. After long-term use, the filter screen 19 needs to be disassembled and cleaned. At this time, the staff opens the box door 16 and pulls the plug rods 21 at both ends upward. Under the action of the spring 22, the plug rods 21 can drive the slider 25 to move upward and leave the limiting groove inside the filter screen 19 and the mounting plate 20. The staff can then pull the filter screen 19 outward to remove it, which improves the filtration effect and convenience of the entire device. The delivery pump 10 in this device is a pneumatic diaphragm pump, and the return pump 11 is a peristaltic pump.

[0030] Working principle: During use, the operator opens the door of the spray box 1, then places one end of the insulator core rod to be coated with glue into the turntable 17. Subsequently, the upper cylinder 5 is activated to drive the drive assembly downward, so that the turntable 2 can contact the other end of the core rod, thus fixing the core rod. Then, the door is closed, and the delivery pump 10 is activated to deliver the glue inside the storage tank 13 through the delivery pipe 9 to the inside of the arc frame 15, and spray it outward along the nozzle 26 to complete the glue coating operation on the surface of the core rod. In order to improve the overall glue coating uniformity, the motor inside the drive box 7 is activated to drive the turntable 2 to rotate, so that the core rod inside can rotate for spraying, which greatly improves the uniformity of the insulator core rod during glue coating.
