[0014] Preferably, a control cabinet is further included, which is connected to the spray assembly by electrical signals, and is used to control the spray assembly to automatically spray the gas meter.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] An ultrasonic gas meter automatic spraying device, wherein the fixed seat assembly mainly fixes the gas meter to ensure the stable position of the gas meter during the spraying process; a track is slidably connected to the fixed seat assembly, and the gas meters can be sprayed in batches through the sliding connection between the track and the fixed seat assembly; the nozzle head changes the grease from a paste to an aerosol state through the air pressure provided by the pressurizing device, so that the grease is evenly dispersed, ensuring the control of the coating process.

[0017] Furthermore, the ultrasonic gas meter automatic spraying device controls the movement of the nozzle head through the cooperation of the cantilever assembly and the connecting rod assembly, thereby achieving efficient and high-quality spraying of the gas meter.

[0018] Furthermore, through the coordinated use of the first connecting rod and the second connecting rod, the connecting rod assembly can not only achieve a stable connection between the nozzle head and the cantilever assembly, but also can adjust the position of the nozzle head within a certain range.

[0019] Furthermore, the setting of the silo allows the grease to be stored directly near the nozzle head, avoiding problems such as blockage and leakage that may occur during the grease delivery process. In this way, the spraying operation can be carried out more continuously and stably, improving the spraying efficiency. The pressurizing device can ensure that the grease obtains sufficient pressure at the nozzle head, so that it can be sprayed at a higher speed and more uniform flow rate. This high-pressure spraying method helps the grease adhere better to the gas meter and improves the uniformity and coverage of the spraying.

[0020] Furthermore, the first cantilever and the second cantilever are supported by the rotating shaft to rotate relative to each other, thereby adjusting the angle and position of the nozzle head.

[0021] Furthermore, the fixing groove provided on the first cantilever provides accurate positioning and fixing for the assembly of the rotating shaft. The shape and size of the fixing groove match the rotating shaft, ensuring that the rotating shaft can be stably embedded therein and is not prone to shaking or deviation.

[0022] Furthermore, the arrangement of the driving device enables the first connecting rod to move up and down accurately during the spraying process, thereby achieving accurate control of the spraying height of the nozzle head.

[0023] Furthermore, the mobile tray, as the base part of the fixed seat assembly, is slidably assembled on the track. This design enables the mobile tray to move smoothly along the track, thereby driving the gas meter fixed thereon to adjust its position. The linear motion characteristics of the track ensure the accuracy and stability of the movement of the mobile tray, so that the gas meter can be accurately moved to the bottom of the spray assembly for spraying. The connector ensures a firm connection between the fixed frame and the mobile tray. The fixed frame ensures that the gas meter will not shake or shift during the spraying process.

[0024] Furthermore, one end of the first cantilever is connected to a column for supporting the spraying assembly. This design not only provides stable and reliable support for the spraying assembly, but also enhances the structural strength and stability of the entire spraying system.

[0025] Furthermore, the control cabinet realizes precise control of the spraying components through electrical signal connection, ensuring the efficient and stable operation of the ultrasonic gas meter automatic spraying device. Its application not only improves the spraying quality and efficiency, but also reduces the labor intensity and production costs of operators, providing strong support for the automated production of the gas meter manufacturing industry.

DETAILED DESCRIPTION

[0034] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0035] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0036] like Figures 1 to 4 As shown, an automatic spraying device for ultrasonic gas meters includes a fixed seat assembly 1, a track 2, a spraying assembly 3, a cantilever assembly 4, a connecting rod assembly 5, a column 6, and a control cabinet 7; the control cabinet 7 is connected to the spraying assembly 3 by electrical signals, and the control cabinet 7 is used to control the spraying assembly 3 to automatically spray the gas meter. The control cabinet 7 also has monitoring and alarm functions. It can monitor the working status of the spraying assembly and the remaining amount of grease in real time. Once an abnormal situation or insufficient grease is found, an alarm signal is issued in time to remind the operator to deal with it. This helps to ensure the continuity and stability of the spraying process and avoid the deterioration of spraying quality or production interruption due to equipment failure or insufficient grease. The control cabinet 7 improves the spraying quality and efficiency, reduces the labor intensity and production cost of the operator, and provides strong support for the automated production of the gas meter manufacturing industry.

[0037] Among them, the spraying assembly 3 includes a nozzle head 3-1, a pressurizing device 3-2 and a silo 3-3; a silo 3-3 for storing grease is installed above the nozzle head 3-1, and a pressurizing device 3-2 for providing pressure to the nozzle head 3-1 is connected above the silo 3-3. The direct connection between the pressurizing device 3-2 and the silo 3-3 ensures the stability and continuity of the grease supply. The grease in the silo 3-3 can flow smoothly to the nozzle head 3-1 after being subjected to the pressure applied by the pressurizing device 3-2, avoiding problems such as grease blockage or leakage, and improving the reliability of the spraying operation; the pressurizing device 3-2 generally achieves pressurization through a cylinder and a piston. The pressurizing device 3-2 uses air pressure to convert the grease paste into an aerosol through the fine-pore nozzle head 3-1, so that the grease is evenly dispersed to ensure the control of the coating process.

[0038] The spraying assembly 3 is mounted on the column 6. The column 6 serves as a supporting structure and can bear the weight of the spraying assembly 3 to ensure that it maintains a stable posture and position during operation; this helps prevent the spraying assembly 3 from shaking or shifting during the spraying process, thereby ensuring the accuracy and consistency of the spraying.

[0039] The connecting rod assembly 5 is used to connect the nozzle head 3-1 and the cantilever assembly 4, wherein the connecting rod assembly 5 includes a first connecting rod 5-1 and a second connecting rod 5-2; the first connecting rod 5-1 is assembled at one end of the cantilever assembly 4, and the second connecting rod 5-2 is used to connect the first connecting rod 5-1 and the nozzle head 3-1.

[0040] Furthermore, the cantilever assembly 4 includes a first cantilever 4-1, a second cantilever 4-2, and a rotating shaft 4-3 provided between the first cantilever 4-1 and the second cantilever 4-2, and the first cantilever 4-1 and the second cantilever 4-2 are rotatably connected via the rotating shaft 4-3. The first cantilever 4-1 is provided with a fixing groove 4-1-1 for assembling the rotating shaft 4-3, and the rotating shaft 4-3 passes through one end of the second cantilever 4-2 and is fitted into the fixing groove 4-1-1. The shape and size of the fixing groove 4-1-1 match the rotating shaft 4-3, ensuring that the rotating shaft 4-3 can be stably embedded therein and is not prone to shaking or deviation; the first cantilever 4-1 rotates around the column 6, and the second cantilever 4-2 rotates around the rotating shaft 4-3, thereby driving other components to rotate, so that the nozzle head 3-1 can be moved to an accurate position.

[0041] The other end of the second cantilever 4-2 is provided with a driving device 4-2-1 for controlling the up and down movement of the first connecting rod 5-1. The setting of the driving device 4-2-1 enables the first connecting rod 5-1 to move up and down accurately during the spraying process, thereby realizing accurate control of the spraying height of the nozzle head 3-1. This design can ensure that the spraying distance between the nozzle head 3-1 and the gas meter is always maintained within the optimal range, avoiding uneven spraying caused by too far a distance or grease waste caused by too close a distance.

[0042] The spraying assembly 3 is assembled on the top of the fixed seat assembly 1. The fixed seat assembly 1 is slidably assembled on the track 2 set next to the column 6. The fixed seat assembly 1 includes a fixed frame 1-1, a connecting piece 1-2 and a movable tray 1-3; the movable tray 1-3 is slidably assembled on the track 2, the connecting piece 1-2 is used to connect the fixed frame 1-1 and the movable tray 1-3, and the fixed frame 1-1 is used to fix the gas meter. The design of the fixed seat assembly 1 enables the ultrasonic gas meter automatic spraying device to stably fix the gas meter, and through the sliding of the movable tray 1-3 on the track 2, the position of the gas meter can be accurately adjusted. Through the movement of the fixed seat assembly 1 on the track 2, in conjunction with the automatic spraying of the spraying assembly 3, the ultrasonic gas meter automatic spraying device can perform batch spraying, and the accuracy and efficiency of the spraying operation are improved.

[0043] Furthermore, the automatic spraying device of the ultrasonic gas meter is linked with the robot, and the spraying component 3 is fixed at the end of the four-axis robot. Under the automatic control of the robot, the spraying component 3 can be moved to the specified position accurately and stably, with fast and reliable movements and good consistency.
