The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a spray head for a continuous casting slab aluminum wire marking machine, such as... Figure 1-4As shown, the spray head of the continuous casting slab aluminum wire marking machine includes: a nozzle body 1 for spraying high-pressure gas, the nozzle body 1 being provided with a gas guide pipe 2; an isolation plate 3 installed on the nozzle body 1 for preventing material splashing back, the isolation plate 3 being provided with an exhaust port; a collector cylinder 4 fixed on the nozzle body 1 for assisting gas pressurization; a threaded cylinder 5 installed on the collector cylinder 4 and connectable to the aluminum wire marking machine for stabilizing the nozzle body 1; and an isolation structure provided inside the threaded cylinder 5 for isolating materials and filtering air.

[0024] In this embodiment, the isolation structure inside the isolation plate 3 and the threaded cylinder 5 effectively prevents material splashing and impurities from entering the spraying system, thereby greatly reducing the possibility of nozzle clogging. The design of the manifold 4 enhances the gas pressure and flow rate, allowing the aluminum wire to adhere more firmly to the steel billet, improving the uniformity and firmness of the spraying. The stable connection between the threaded cylinder 5 and the aluminum wire marking machine ensures that the spraying head will not shake or fall off during use, further improving the accuracy and reliability of the spraying.

[0025] In a further preferred embodiment of the present invention, the isolation structure includes: a cylinder 6 threadedly installed inside the threaded cylinder 5; a filter screen 7 fixed inside the cylinder 6 for isolating materials, the filter screen 7 also for filtering air, the number of the filter screen 7 being no less than three, and the plurality of filter screens 7 being arranged sequentially from the threaded cylinder 5 to the nozzle body 1 according to their mesh inner diameter length; and a handle 8 installed inside the cylinder 6 for providing an operating grip point.

[0026] In this embodiment, by increasing the number of filters 7 and adopting a step-by-step filtration design, the filtration effect is effectively improved, further reducing the possibility of nozzle clogging. The fine filtration of filters 7 ensures that the air entering the spraying system is pure and free of impurities, thereby improving the uniformity and adhesion of the spray. At the same time, the stable connection between the cylinder 6 and the threaded cylinder 5 also enhances the stability of the system. The design of the handle 8 allows operators to easily disassemble and clean the filters 7, reducing maintenance costs. In addition, the handle 8 can also serve as an auxiliary tool for installing and disassembling the cylinder 6, improving operational efficiency.

[0027] In a further preferred embodiment of the present invention, a fixing plate 9 is installed on one side of the nozzle body 1, an electric telescopic rod 10 is rotatably installed on the fixing plate 9, an extension frame 11 is installed on the output rod of the electric telescopic rod 10, and a cleaning hook 13 for cleaning impurities inside the nozzle body 1 is fixed on the extension frame 11.

[0028] In this embodiment, with the cooperation of the electric telescopic rod 10 and the extension frame 11, the cleaning hook 13 can flexibly and quickly extend into the inside of the nozzle body 1 for cleaning, which greatly improves the cleaning efficiency. Regularly cleaning the impurities and blockages inside the nozzle body 1 can extend the service life of the nozzle, reduce the frequency of nozzle replacement, and thus reduce maintenance costs. After cleaning, the nozzle body 1 can remain unobstructed, ensuring that high-pressure gas and molten aluminum wire can be sprayed out stably and evenly, thereby improving the coating quality and stability.

[0029] In a further preferred embodiment of the present invention, a blocking plate 12 for sealing the nozzle body 1 is fixed on the unblocking hook 13, and a sealing gasket 14 for increasing the sealing performance is installed on the blocking plate 12. The sealing gasket 14 can contact the isolation plate 3 to seal the exhaust port.

[0030] In this embodiment, the tight contact between the sealing gasket 14 and the isolation plate 3 effectively seals the exhaust port, preventing the leakage or entry of gas or impurities, thus improving the sealing performance and cleanliness of the nozzle. The design of the blocking plate 12 and the sealing gasket 14 allows for easy closure of the opening of the nozzle body 1 when cleaning or maintaining the nozzle, preventing the entry of external impurities. It also provides operators with a safer and more convenient working environment. By regularly cleaning and sealing the nozzle body 1, the erosion and wear of impurities on the inside of the nozzle can be reduced, thereby extending the service life of the nozzle and enhancing its durability.

[0031] In a further preferred embodiment of the present invention, a rotating shaft 15 is rotatably mounted on the fixed plate 9, and a transmission gear 16 is mounted on both the rotating shaft 15 and the electric telescopic rod 10. The two transmission gears 16 mesh with each other for transmission, and a power box 19 for driving the rotating shaft 15 to rotate is mounted on the fixed plate 9.

[0032] In this embodiment, when the power box 19 is started, it drives the rotating shaft 15 to rotate. Since the rotating shaft 15 and the transmission gear 16 on the electric telescopic rod 10 are meshed, the rotation of the rotating shaft 15 will drive the transmission gear 16 on the electric telescopic rod 10 to rotate, thereby adjusting the angle of the electric telescopic rod 10. No manual operation is required, which greatly improves the convenience of operation. The automated operation makes the process of clearing blockages and sealing the nozzle body faster and more efficient, reduces the waiting time of manual operation, and improves work efficiency.

[0033] In a further preferred embodiment of this utility model, the power box 19 is provided with a servo motor and a gear reducer. The output shaft of the servo motor is connected to the input shaft of the gear reducer, and the output shaft of the gear reducer is connected to the rotating shaft 15. The gear reducer is used to adjust the torque of the output shaft of the servo motor.

[0034] In this embodiment, when the servo motor starts, its output shaft begins to rotate and transmits power to the rotating shaft 15 through a gear reducer. The gear reducer reduces the speed of the servo motor through internal gear meshing and deceleration, while increasing the torque of the output shaft. In this way, the rotating shaft 15 can rotate at a stable and controllable speed and torque, thereby driving the electric telescopic rod 10 to perform precise telescopic movements. The fast response and precise control of the servo motor make the angle adjustment of the electric telescopic rod 10 faster and more efficient, thereby improving the working efficiency of the entire system.

[0035] In a further preferred embodiment of the present invention, the electric telescopic rod 10 is movably fitted with a protective cover 17 for protecting the transmission gear 16. The protective cover 17 is covered with double-sided adhesive 18 that can be adhered to the fixing plate 9. The double-sided adhesive 18 is used to connect the fixing plate 9 and the protective cover 17.

[0036] In this embodiment, when the protective cover 17 needs to be installed, the operator only needs to put the protective cover 17 on the outside of the electric telescopic rod 10 and stick it to the fixing plate 9 with double-sided tape 18. The protective cover 17 can prevent external impurities, moisture and other substances from entering the transmission system, avoiding failures or damage caused by these factors, thereby improving the safety of the system. By protecting the transmission gear 16, the protective cover 17 can ensure the normal operation of the transmission system, reduce downtime caused by damage to the transmission gear 16, thereby enhancing the reliability of the system. The use of double-sided tape 18 makes the installation and removal of the protective cover 17 simple and quick, without the need for additional tools or equipment, thereby simplifying the installation and maintenance process.

[0037] In a further preferred embodiment of this utility model, a support rod connected to the nozzle body 1 is installed on the collector cylinder 4 to support the collector cylinder 4, the air guide pipe 2 is made of high temperature resistant glass, and the air guide pipe 2 is connected to the exhaust port.

[0038] In this embodiment, high-pressure gas is introduced into the manifold 4 through the air guide pipe 2. After being guided by the manifold 4, it is evenly distributed into the interior of the nozzle body 1. The support rod ensures the stability and positional accuracy of the manifold 4, avoiding poor spraying effect caused by shaking or displacement. The air guide pipe 2, made of high-temperature resistant glass, can work stably for a long time in a high-temperature environment, ensuring the reliability and durability of the entire system, while also enabling visualization of the nozzle blockage status.

[0039] In summary, compared with related technologies, this device, by setting up the isolation plate 3, the collection cylinder 4, and the isolation structure, effectively prevents material splashing and impurities from entering the spraying system, greatly reducing the possibility of nozzle clogging. It also enhances gas pressure and flow rate, improving the uniformity and adhesion of the spray. Increasing the number of filter screens 7 and adopting a step-by-step filtration design further improves the filtration effect. The installation of the cleaning hook 13 and the blockage plate 12 structure facilitates the cleaning of impurities and blockages inside the nozzle, extending the nozzle's service life. The use of the power box 19 and the servo motor enables automated control of the electric telescopic rod 10, improving operational convenience and work efficiency.
