Description

Technical Field

[0001] This utility model relates to the field of ultrasonic nozzles, specifically an ultrasonic coating nozzle. Background Technology

[0002] An ultrasonic nozzle consists of an ultrasonic transducer, a vibrator, and a nozzle. Its core structure is the ultrasonic transducer, which can convert electrical signals into high-frequency mechanical vibrations. The vibrations act on the liquid through the nozzle, thus atomizing the liquid into tiny particles. It is widely used for uniform coating of roll materials such as non-woven fabrics and glass. A larger coating width can be obtained by combining multiple heads in parallel, making it suitable for mass production coating processes.

[0003] Paint is applied to the surface of an object to be protected or decorated, forming a continuous film that adheres firmly to the object. When spraying paint, it is often sprayed out of the nozzle in the form of a mist. Traditional nozzles mainly achieve atomization by the shearing action of the liquid as it passes through the nozzle at high speed and the air. Under high pressure, the liquid passes through a narrow nozzle and generates intense friction with the surrounding air to form atomization. Because it depends on the pressure of the liquid and the size of the nozzle, the size of the droplets is usually difficult to control and is easily affected by factors such as flow rate and pressure. When spraying paint, the material is prone to clogging in the nozzle and the spraying effect is poor. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the difficulty in controlling the pressure of the liquid and the size of the nozzle and droplets during the spraying process, which are easily affected by factors such as flow rate and pressure, this invention proposes an ultrasonic coating nozzle.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: an ultrasonic coating nozzle, including a stainless steel outer box, a top cover fixedly connected to the top of the stainless steel outer box, a ring-shaped ultrasonic transducer movably connected to the top of the stainless steel outer box, a sound wave transducer shaft movably connected to the center of the ring-shaped ultrasonic transducer, the outer side of the sound wave transducer shaft penetrating through the center of the top of the top of the top cover, a temperature monitoring hole and a wiring terminal mounting hole respectively opened on the top of the top of the top cover, a conical titanium alloy nozzle fixedly connected to the bottom of the sound wave transducer shaft, the outer side of the conical titanium alloy nozzle penetrating through the interior of the stainless steel outer box, a sealing ring sleeved on the outer side of the bottom of the conical titanium alloy nozzle, a splash shield sleeved on the outer side of the sealing ring, and the splash shield being disposed on the outer side of the sound wave transducer shaft.

[0006] Preferably, the stainless steel outer box is fitted with a clamp seat on the outside, and the clamp seat is internally threaded with an internal hexagon bolt, which penetrates the interior of the clamp seat and is threadedly connected to the locking end.

[0007] Preferably, the outer side of the stainless steel outer box is provided with a pressure regulating valve air inlet, the inside of the pressure regulating valve air inlet is provided with a threaded groove, the outer side of the threaded groove is threaded with a pin, and the other end of the pin is rotatably connected to a pressure regulator.

[0008] Preferably, an air tube is fixedly connected to the top of the pin, and the air tube is made of a flexible material.

[0009] Preferably, the angle of the conical titanium alloy nozzle is set to 184°, and a 1mm annular gap air guide groove is opened between the tail end of the stainless steel outer box and the surface of the acoustic transducer shaft.

[0011] Preferably, the upper cover has positioning holes on both sides, and the positioning groove of the upper cover is located between the round hole grooves on both sides of the locking end.

[0012] The advantages of this utility model are:

[0013] This invention involves directing the slurry to be sprayed from the top into the internal shaft of the ultrasonic nozzle. The shaft is surrounded by a ring-shaped ultrasonic transducer, which emits a 60Hz frequency that is transmitted to the titanium alloy nozzle. This high-frequency vibration of the internal liquid transforms it into nano-sized droplets. An air inlet is located on the side of the outer casing, allowing gas to enter the nozzle's internal cavity and create pressure. This pressure is then released from the gap between the bottom nozzle and the outer casing, forming a vertical airflow that evenly distributes the droplets further. A pressure regulating device is added to the outside of the conical titanium alloy nozzle to control the internal gas pressure, thereby controlling the paint spray flow rate. A quick-installable anti-splash shield is also added to the outside of the conical titanium alloy nozzle to prevent excessive paint spraying and out-of-bounds coverage when spraying smaller areas, thus improving spray quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0024] This application discloses an ultrasonic coating nozzle. (Refer to...) Figure 1 and Figure 4An ultrasonic coating nozzle includes a stainless steel outer casing 1, with a top cover 3 fixedly connected to the top of the casing 1. A ring-shaped ultrasonic transducer 2 is movably connected to the top of the casing 1. The maximum amplitude of the ring-shaped ultrasonic transducer 2 is designed at the very front end of a conical titanium alloy nozzle 7. When liquid is transported from the rear of the conical titanium alloy nozzle 7 to the front end, it is atomized by the high-frequency ultrasonic vibration at the front end. The liquid mist can then be delivered to the object being coated or a specific space via a certain amount of carrier gas. The center position of the ring-shaped ultrasonic transducer 2 is movable. The acoustic transducer shaft 4 is dynamically connected, and the outer side of the acoustic transducer shaft 4 passes through the center of the top of the upper cover 3. The top of the upper cover 3 is provided with a temperature monitoring hole 8 and a wiring terminal mounting hole 10. The bottom end of the acoustic transducer shaft 4 is fixedly connected to a conical titanium alloy nozzle 7, and the outer side of the conical titanium alloy nozzle 7 passes through the interior of the stainless steel outer box 1. A sealing ring 5 is fitted on the outer side of the bottom end of the conical titanium alloy nozzle 7, and a splash guard 6 is fitted on the outer side of the sealing ring 5. The splash guard 6 is set on the outer side of the acoustic transducer shaft 4 to prevent spraying beyond the boundary.

[0025] Reference Figure 3 and Figure 4 The outer side of the stainless steel outer box 1 is fitted with a clamp seat 11. The clamp seat 11 is internally threaded with an internal hex bolt 14. The internal hex bolt 14 passes through the interior of the clamp seat 11 and is threadedly connected to the locking end 12. The internal hex bolt 14 is used to lock the locking end 12 and the clamp seat 11.

[0026] Reference Figure 4 The outer side of the stainless steel outer box 1 is provided with a pressure regulating valve air inlet 9. The air inlet 9 of the pressure regulating valve has a threaded groove 13 inside. When spraying is required, the pin 15 is inserted into the threaded groove 13 on the outer side of the stainless steel outer box 1. The other end of the pin 15 is rotatably connected to the pressure regulator 16. By rotating the knob on the outside of the pressure regulator 16, the pressure regulator 16 is adjusted. The device for regulating air pressure is used to control the internal gas pressure value, thereby controlling the amount of paint spraying flow.

[0027] Reference Figure 1 The top of the pin 15 is fixedly connected to an air tube 17, which is made of a flexible material and is used to connect to the outside and pressurize the internal air.

[0028] Reference Figure 2 The angle of the conical titanium alloy nozzle 7 is set to 184°, which makes the sound wave frequency transmission more uniform and efficient. A 1MM annular gap air guide hole is opened between the tail end of the stainless steel outer box 1 and the surface of the sound wave transducer core 4. The gas enters the internal cavity of the nozzle and forms air pressure. It comes out from the gap between the bottom nozzle and the outer box to form a vertical airflow, which can blow the mist droplets evenly to a farther place and effectively improve the uniformity of spray.

[0029] Reference Figure 2 The tapered titanium alloy nozzle 7 has an upper diameter of 4MM and a tail diameter of 0.8mm. The micro-hole design, which is larger at the top and smaller at the bottom, effectively reduces processing difficulty, increases yield, and reduces costs.

[0030] Reference Figure 1 The upper cover 3 has positioning holes on both sides. The positioning groove of the upper cover 3 is set between the round hole grooves on both sides of the locking end 12. The upper cover 3 is placed inside the locking end 12, and the locking end 12 and the clamp seat 11 are locked by the internal hex bolt 14 to limit the position of the upper cover 3.

[0031] Working principle: First, the slurry to be sprayed is introduced into the internal shaft of the ultrasonic nozzle through the top hole. The acoustic transducer shaft 4 is surrounded by the ring-shaped ultrasonic transducer 2. The ring-shaped ultrasonic transducer 2 emits a 60Hz frequency and transmits it to the conical titanium alloy nozzle 7, which transforms the internal liquid into nano-sized mist droplets through high-frequency vibration. The stainless steel outer box 1 has an air inlet on the side, and the gas enters the interior of the pressure regulator 16. The air pressure is generated inside the nozzle cavity and sprayed out from the gap between the bottom conical titanium alloy nozzle 7 and the stainless steel outer box 1, thus forming a vertical airflow that can evenly blow the mist droplets to a farther place for spraying paint. When using it for spraying, the pin 15 is inserted into the threaded groove 13 on the outside of the stainless steel outer box 1. The other end of the pin 15 is rotatably connected to the pressure regulator 16. By rotating the knob on the outside of the pressure regulator 16, the pressure regulator 16 is adjusted to regulate the air pressure and control the internal gas pressure value, thereby controlling the paint spraying flow rate. When it is necessary to spray a small area, the anti-splash cover 6 is set on the outside of the acoustic transducer shaft core 4 to limit the spraying range.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
