Description

Technical Field

[0001] This utility model relates to the field of wire coating technology, and in particular to a DC power cord insulation coating device. Background Technology

[0002] With the continuous development of technology, the application of DC power cords is becoming increasingly widespread, especially in communication, power, and electronic equipment, where the requirements for power cord insulation coating are also rising. To ensure the safety and stability of power cords, the quality of the insulation coating is paramount. Traditional DC power cord insulation coating equipment often relies on manual operation or simple automation technology, and problems such as paint waste, inconvenient recycling, and uneven coating still exist during the coating process. This not only affects the coating effect but also leads to wasted material costs. Therefore, developing equipment with an efficient paint recycling and closed-loop circulation system has become an important direction for improving DC power cord insulation coating technology.

[0003] Most existing DC power line insulation coating equipment uses a simple spraying system to spray coating onto the surface of the power line, achieving the coating effect by controlling the spraying method of the spray gun or nozzle. These devices are typically equipped with basic storage tanks and spraying devices, with the coating material transported from the storage tank to the spraying area via gravity or a pumping system. During the coating process, operators adjust the coating time and spray volume as needed. However, because the coating cannot be effectively recycled and reused, excess coating is usually discarded or needs to be replenished periodically, leading to material waste and increased costs.

[0004] However, the biggest problem with existing technologies is that the coatings cannot be effectively recycled and reused. Due to the lack of a closed-loop coating recycling system, excess or underutilized coatings are often wasted during the coating process, requiring continuous replenishment of new coatings, which directly leads to increased material costs. Furthermore, coating waste not only affects production costs but also has adverse environmental impacts. Therefore, a DC power line insulation coating device is proposed to address these issues. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a DC power line insulation coating device, which aims to improve the existing technology that lacks a closed-loop circulation system, resulting in waste of coating, ineffective recycling and reuse of coating, and the need for continuous replenishment, which increases material costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A DC power line insulation coating device includes a support frame, a spray box fixedly connected to the top of the support frame, a first fixing ring fixedly connected to the side wall of the support frame, a filter plate fixedly connected to the inner wall of the spray box, a trapezoidal column fixedly connected to the bottom of the spray box, and a circulation component provided at the bottom of the support frame. The circulation assembly includes a storage tank, the outer wall of which is located at the bottom of the support. A third connecting pipe is fixedly connected to the outer wall of the storage tank. A second circulation pump is fixedly connected to the top of the third connecting pipe. Another third connecting pipe is fixedly connected to the output end of the second circulation pump. One end of the third connecting pipe is fixedly connected to the inside of the spray box, and a spray nozzle is fixedly connected to the other end. A second connecting pipe is fixedly connected to the inside of the storage tank. A first circulation pump is fixedly connected to one end of the second connecting pipe. A first connecting pipe is fixedly connected to the output end of the first circulation pump. The outer wall of the first connecting pipe is fixedly connected to the bottom of the trapezoidal column.

[0007] As a further description of the above technical solution: A drying chamber is fixedly connected to the top of the support frame, a fan is fixedly connected inside the drying chamber, and a heating wire is fixedly connected to the inner wall of the drying chamber in a ring shape.

[0008] As a further description of the above technical solution: The top of the support is fixedly connected to a hollow trough plate, the inner wall of the hollow trough plate is rotatably connected to a rotating wheel, and the side wall of the hollow trough plate is set on the inner wall of the drying oven.

[0009] As a further description of the above technical solution: A second fixing ring is fixedly connected to the top of the bracket, and a collar is fixedly connected inside the second fixing ring.

[0010] As a further description of the above technical solution: A fixed post is slidably connected to the inner wall of the collar, and a clamping ring is fixedly connected to one end of the fixed post.

[0011] As a further description of the above technical solution: A baffle is fixedly connected to one end of the fixed column, and the side wall of the baffle is slidably connected to the side wall of the second fixed ring.

[0012] As a further description of the above technical solution: A spring is provided on the outer wall of the fixed column. One end of the spring is fixedly connected to the outer wall of the fixed column, and the other end of the spring is fixedly connected to one end of the collar.

[0013] As a further description of the above technical solution: The clamping ring sidewall is slidably connected to the second fixed ring sidewall, and the clamping ring sidewall is slidably connected to the spray box sidewall.

[0014] This utility model has the following beneficial effects: 1. In this utility model, paint is collected by a trapezoidal column at the bottom of the spray box, then transported through a first connecting pipe. A first circulation pump then pumps the paint through a second connecting pipe into a storage tank. Subsequently, a second circulation pump circulates the paint in the storage tank through a third connecting pipe, achieving a closed-loop paint circulation system. This solves the problem of paint waste without a closed-loop circulation system, the inability to effectively recycle and reuse paint, the need for continuous replenishment, which increases material costs, and reduces the material cost of the DC power line insulation coating equipment.

[0015] In this invention, the spring's rebound effect drives the fixed column to move, and the movement of the fixed column then moves the clamping ring at one end, achieving the effect of adaptive clamping of the circuit. This solves the problem that the inability to adaptively clamp the circuit means that the equipment cannot provide sufficient clamping force when facing power cords of different sizes, specifications, or shapes, resulting in uneven coating or inaccurate positioning, thus improving the adaptability of the DC power cord insulation coating equipment.
