Abstract
Description
Technical Field
[0001] This utility model relates to the field of nozzle technology, and more specifically, to a coating device for drone parts with an adjustable nozzle structure. Background Technology
[0002] In the field of metal products, the processing of drone parts requires coating equipment to evenly coat the surface with anti-corrosion paint and other coating materials. This can form a barrier between the metal and the external environment (such as humid air, acid rain, corrosive chemicals, etc.), preventing or delaying the erosion of the metal by corrosive media, thereby extending the service life of metal products.
[0003] To maintain coating uniformity, atomized spraying is generally required, where gas and liquid collide to form atomized particles. However, existing devices do not allow for convenient adjustment of the atomized particle size to meet specific requirements, resulting in poor uniformity of the finished product. When spraying different materials, smaller particles adhere better but have lower spraying efficiency, while larger particles easily cause uneven coating. Therefore, we propose a coating device for UAV components with an adjustable nozzle structure. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a coating equipment for drone parts with an adjustable nozzle structure to solve the technical problem that the current nozzle structure is inconvenient to adjust the atomized particle size, which easily affects the processing efficiency and the quality of the finished product.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a coating equipment for drone parts with an adjustable nozzle structure, including a nozzle head, a rotary nozzle mechanism, a rotating mechanism, and an adjusting mechanism. Two nozzle heads are provided, and the two nozzle heads are respectively installed at both ends of an assembly frame. A positioning ring is sleeved on the outer side of each nozzle head. Feed pipes are installed through both sides of the upper end of each nozzle head. The rotating mechanism is rotatably installed inside the upper end of the nozzle head. The adjusting mechanism is installed inside the lower end of the nozzle head, and the adjusting mechanism and the rotating mechanism are connected by a linkage mechanism. The rotary nozzle mechanism is threadedly installed at the lower end of the nozzle head. The rotary nozzle mechanism consists of an assembly nozzle and an inner cone. The inner cone is located inside the assembly nozzle. A discharge hole is formed in a circular array on the outer side of the lower end of the assembly nozzle.
[0006] In use, the spraying liquid and airflow are introduced through two separate feed pipes. The spraying liquid enters the inner rotating cylinder, is guided through the insertion hole into the assembly nozzle, and then flows into the liquid collection ring of the inner cone. The airflow passes through the protrusion and enters the lifting cylinder through the air outlet, then is guided into the assembly nozzle through the inner side of the pressure cap. A narrow gap is formed between the lower end of the pressure cap and the inner cone. The airflow passes through this gap and blows towards the spraying liquid in the liquid collection ring. High-intensity air pressure atomizes the spraying liquid, causing the atomized particles to be sprayed outwards through the discharge hole. The rotating nozzle mechanism is assembled using a spiral method. The inner cone is inserted and positioned on the assembly hole. The convenient assembly and disassembly design facilitates maintenance and allows for easy analysis of the formation process. The inner cone structure of the atomizing particles is replaced to reduce maintenance difficulty. The motor on the upper side of the nozzle head is started to drive the drive teeth to rotate. The drive teeth mesh with the inner tooth groove of the inner rotating cylinder to drive it to rotate. The inner rotating cylinder drives the lifting cylinder to rotate through the linkage mechanism. During the rotation of the lifting cylinder, the upper end and the lower end of the upright rod are connected by the screw thread to achieve lifting and lowering. The distance between the pressure cap at the lower end of the lifting cylinder and the inner cone body becomes smaller, so that the liquid is subjected to stronger shearing force and abrupt breaking action when passing through the conical area, thereby making the atomized droplets smaller and more uniform. Through the above structural design, the atomized particle size can be adjusted by adjusting the distance between the pressure cap and the inner cone body, which can be adapted to the spraying operation of different materials and ensure the practicality of the device.
[0007] Preferably, an assembly hole is provided in the middle of the assembly nozzle, and the lower end of the inner cone is inserted into the assembly hole, and an annular liquid collection ring is provided at the lower outer end of the inner cone.
[0008] Preferably, the rotating mechanism is composed of an inner rotating cylinder, and a protrusion is provided in the middle of the inner rotating cylinder. Insertion holes are provided on both sides of the bottom of the inner rotating cylinder, and meshing grooves are provided in an annular array on the upper inner side of the inner rotating cylinder.
[0009] Preferably, the linkage mechanism consists of a feed tube and a connecting ring. The feed tube is installed through both upper ends of the connecting ring, and the upper end of the feed tube is inserted into the insertion hole. The inner side of the connecting ring is provided with a slider end.
[0010] Preferably, the adjusting mechanism consists of a pressure cap and a lifting cylinder, with the pressure cap fixed at the lower end of the lifting cylinder. An air vent and an adjusting groove are provided on the outer side of the upper end of the lifting cylinder, and the air vent and the adjusting groove are staggered. The slider end of the connecting ring is slidably installed in the adjusting groove.
[0011] Preferably, the lower end of the pressure cap has a conical notch, which is connected to the inner cone. The top of the nozzle head is fixed with a vertical rod, and the threaded end of the vertical rod is threadedly connected to the upper opening of the lifting cylinder.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model designs a rotary nozzle mechanism, in which the spraying liquid and airflow are introduced through two feed pipes respectively. After the spraying liquid enters the inner rotating cylinder, it is guided into the assembly nozzle through the insertion hole, and then flows into the liquid collection ring of the inner cone. The airflow enters the lifting cylinder through the air outlet after passing through the protrusion, and then is introduced into the assembly nozzle through the inner side of the pressure cap. A narrow gap is formed between the concave end of the pressure cap and the inner cone. The airflow blows the spraying liquid through the gap to the liquid collection ring, and the spraying liquid is atomized by high-intensity air pressure. Then, the atomized particles are sprayed outward through the discharge hole. The rotary nozzle mechanism is assembled by a spiral. The inner cone is inserted and positioned on the assembly hole. The convenient installation and removal design facilitates maintenance and makes it easy to replace the inner cone structure that forms the atomized particles, reducing the difficulty of maintenance.
[0014] 2. This utility model also incorporates a rotating mechanism. The motor on the upper side of the nozzle head drives the drive teeth to rotate. The drive teeth mesh with the inner tooth groove of the inner rotating cylinder, causing it to rotate. The inner rotating cylinder, through a linkage mechanism, drives the lifting cylinder to rotate. During the rotation of the lifting cylinder, the upper end and the lower end of the upright rod are connected by a threaded joint to achieve lifting and lowering. The distance between the lower end pressure cap and the inner cone of the lifting cylinder decreases, causing the liquid to experience stronger shearing and breaking forces when passing through the conical area. This results in finer and more uniform atomized droplets. Through the above structural design, the distance between the pressure cap and the inner cone can be adjusted to regulate the atomized particle size, adapting to the spraying operations of different materials and ensuring the practicality of the device.

The inner side of the connecting ring 702 is provided with a slider end. The spraying liquid and airflow are introduced through two feed tubes 101 respectively. After the spraying liquid enters the inner rotating cylinder 501, it is guided into the assembly nozzle 401 through the insertion hole 503, and then flows into the liquid collection ring port 403 of the inner cone 402. The airflow enters the lifting cylinder 603 through the air outlet 601 after passing through the protrusion 502, and then enters the assembly nozzle 401 through the inner side of the pressure cap 602. The lower end of the pressure cap 602 has a notch. A narrow gap is formed between the inner cone 402 and the sprayed liquid. The airflow passes through the gap and blows the sprayed liquid into the liquid collection ring 403. The sprayed liquid is atomized by high-intensity air pressure, and then the atomized particles are sprayed outward through the discharge hole 405. The rotary nozzle mechanism 4 is assembled by a spiral. The inner cone 402 is inserted and positioned on the assembly hole 404. The convenient installation and removal design facilitates maintenance and makes it easy to replace the inner cone 402 structure that forms the atomized particles, reducing the difficulty of maintenance.
[0024] like Figures 2 to 7As shown, this utility model relates to a coating equipment for drone parts with an adjustable nozzle structure, including a nozzle head 1, a rotating nozzle mechanism 4, a rotating mechanism 5, and an adjusting mechanism 6. The rotating nozzle mechanism 4 is threadedly installed at the lower end of the nozzle head 1. The rotating nozzle mechanism 4 consists of an assembly nozzle 401 and an inner cone 402. An assembly hole 404 is provided in the middle of the assembly nozzle 401, and the lower end of the inner cone 402 is inserted into the assembly hole 404. An annular liquid collection ring 403 is provided at the lower outer end of the inner cone 402. The inner cone 402 is located inside the assembly nozzle 401. An annular array of discharge holes 405 is provided on the lower outer side of the assembly nozzle 401. The adjusting mechanism 6 consists of a pressure cap 602 and a lifting cylinder 603. The pressure cap 602 is fixed to the lower end of the lifting cylinder 603. An air vent 601 and an adjusting groove 604 are provided on the upper outer side of the lifting cylinder 603, and the air vent 601 and the adjusting groove 604 are staggered.

The distance between the lower end of the lifting cylinder 603 pressure cap 602 and the inner cone 402 becomes smaller, so that the liquid is subjected to stronger shearing force and abrupt breaking action when passing through the conical area, thereby making the atomized droplets smaller and more uniform. Through the above structural design, the atomized particle size can be adjusted by adjusting the distance between the pressure cap 602 and the inner cone 402, which is suitable for spraying operations of different materials and ensures the practicality of the device.
[0025] Working Principle: This embodiment provides a coating device for drone parts with an adjustable nozzle structure. In use, the coating liquid and airflow are introduced through two feed pipes 101. After entering the inner rotating cylinder 501, the coating liquid is guided through the insertion hole 503 into the assembly nozzle 401, and then flows into the liquid collection ring 403 of the inner cone 402. The airflow passes through the protrusion 502 and enters the lifting cylinder 603 through the air outlet 601, then passes through the inner side of the pressure cap 602 into the assembly nozzle 401. A narrow gap is formed between the lower end recess of the pressure cap 602 and the inner cone 402. The airflow passes through this gap and blows towards the coating liquid in the liquid collection ring 403, atomizing the coating liquid through high-intensity air pressure. The particles are ejected outward through the discharge hole 405. The rotary nozzle mechanism 4 is assembled in a spiral manner. The inner cone 402 is inserted and positioned on the assembly hole 404. The motor on the upper side of the nozzle head 1 is started to drive the drive gear 103 to rotate. The drive gear 103 meshes with the inner tooth groove of the inner rotating cylinder 501 to drive it to rotate. The inner rotating cylinder 501 drives the lifting cylinder 603 to rotate through the linkage mechanism 7. During the rotation of the lifting cylinder 603, the upper end and the lower end of the vertical rod 102 are engaged to achieve lifting and lowering. The distance between the lower end pressure cap 602 of the lifting cylinder 603 and the inner cone 402 becomes smaller, so that the liquid is subjected to stronger shearing force and crushing effect when passing through the conical area, thereby making the atomized droplets finer and more uniform.
