Description

Technical Field

[0001] The utility model relates to the technical field of gas cylinder production, in particular to a surface spraying device for PRO gas cylinder production. Background Technique

[0002] Gas cylinders are containers used to store and transport gases, usually made of high-strength steel. They are widely used in industry, medicine, fire protection and daily life. For example, they store compressed air, oxygen, nitrogen, etc. The main purpose of spraying gas cylinders is to protect the surface of the cylinders from corrosion. During the use of gas cylinders, they are often exposed to various environmental factors such as moisture and salt, which may cause rust or corrosion on the surface of the cylinders. Spraying can form a protective film to prevent these environmental factors from damaging the cylinders, thereby extending their service life.

[0003] At present, the existing device (such as the patent publication number: CN210753443U) discloses a "spraying device". This device locks the spraying can in the tank body through a knob screw, makes the nozzle of the spraying can face the direction of the turntable, places the sample to be sprayed on the turntable cover inside the turntable, and fixes it with a strong magnet if necessary. Start the device, set the spraying parameters, and the turntable starts to rotate to make the spraying results of the samples highly consistent.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: When spraying workpieces with this device, only one workpiece can be sprayed at a time. In the case of a large processing volume, the processing efficiency of this device for workpieces is low, and the practicability is insufficient and needs to be improved. Summary of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the utility model provides a surface spraying device for PRO gas cylinder production, which solves the technical problem of insufficient practicability of the existing device.

[0007] (2) Technical Solutions

[0008] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0009] A surface spraying device for PRO gas cylinder production, including a spraying device body;

[0010] A plurality of auxiliary mechanisms are rotatably installed inside the spraying device body;

[0011] The auxiliary mechanism includes cylindrical members. A first gear is fixedly installed on the circumferential surface of each cylindrical member, and the first gears on each cylindrical member are meshed with each other. A stepped member is provided at the upper end of each cylindrical member, and a motor is embedded in the spraying device body.

[0012] Preferably: A feeding unit and a movable electric spray head unit assembly are respectively provided inside the spraying device body. The feeding port of the movable electric spray head unit assembly is connected to the feeding port of the spraying device body. A second gear is fixedly installed on the output shaft of the motor, and the second gear is meshed with the first gear.

[0013] Preferably: An electric push rod is provided at the upper end of the spraying device body. Springs are symmetrically and fixedly installed on the output shaft of the electric push rod. A square plate is fixedly installed at the lower end of each spring. A limit switch is embedded in the square plate, and the limit switch is adapted to the output shaft of the electric push rod.

[0014] Preferably: The button of the limit switch is of the compression reset type, and a plurality of rotating disks are rotatably installed at the lower end of the square plate.

[0015] Preferably: A flat-top conical member is fixedly installed at the lower end of each rotating disk. A PRO gas cylinder body is provided between each flat-top conical member and the stepped member. A stepped groove and a discharge port are respectively provided inside the PRO gas cylinder body. Each stepped groove is adapted to the stepped member, and each discharge port is adapted to the flat-top conical member.

[0016] (III) Beneficial effects

[0017] 1. By orienting the position of the stepped groove on the PRO gas cylinder body towards the position of the stepped member and placing it, and then waiting until the diameter of the discharge port of the PRO gas cylinder body reaches a matching stage with the diameter of the circumference of the flat-top conical member, at this time, the staff can turn on the motor, so that the output shaft of the motor drives the second gear to rotate and mesh with the first gear, thereby causing one of the first gears to rotate and mesh with the other first gears, so as to drive each cylindrical member and the PRO gas cylinder body to rotate, thus completing the synchronous processing of multiple PRO gas cylinders, improving work efficiency and practicability;

[0018] II. Orient the position of the stepped groove on the PRO gas cylinder body to be processed towards the stepped part and place it. Then, turn on the electric push rod, so that the output shaft of the electric push rod drives the square plate to descend together through the spring. When the diameter of the discharge port reaches a matching stage with the diameter of the circumference of the flat-top conical part, at this time, the flat-top conical part will be stuck at the discharge port. At the same time, the continuous downward pressure of the output shaft of the electric push rod will stretch the spring, and at the same time, the spring will contact the limit switch, thereby enabling the limit switch to send a signal to stop the electric push rod in time, and thus the automatic stop can be completed, which further facilitates the operation of the staff and improves portability.

Detailed Embodiment

[0025] In the embodiment of the present application, by providing a surface spraying device for PRO gas cylinder production, the technical problem of insufficient practicability of the existing device is effectively solved. The PRO gas cylinder body is placed with the position of the stepped groove facing the stepped part. Then, when the diameter of the discharge port of the PRO gas cylinder body reaches a matching stage with the circumference of the flat-top conical part, at this time, the staff can start the motor, so that the output shaft of the motor drives the second gear to rotate and mesh with the first gear, which in turn causes one of the first gears to rotate and mesh with the remaining first gears, thereby driving each cylindrical part and the PRO gas cylinder body to rotate, so as to complete the synchronous processing of multiple PRO gas cylinders, improve work efficiency and practicability. And by placing the PRO gas cylinder body to be processed with the position of the stepped groove facing the stepped part and starting the electric push rod, the output shaft of the electric push rod drives the square plate to descend together through the spring. When the diameter of the discharge port reaches a matching stage with the circumference of the flat-top conical part, at this time, the flat-top conical part will be stuck at the discharge port. At the same time, the continuous downward pressure of the output shaft of the electric push rod will stretch the spring, and the spring will contact the limit switch, so that the limit switch emits a signal to stop the electric push rod in time, and thus the automatic stop can be completed, which further facilitates the operation of the staff and improves portability.

[0026] Embodiment

[0027] As Figures 1 - 4 shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient practicability of the existing device, and the general idea is as follows:

[0028] In view of the problems existing in the prior art, the present utility model provides a surface spraying device for PRO gas cylinder production, including a spraying device body 11;

[0029] A plurality of auxiliary mechanisms are rotatably installed inside the spraying device body 11;

[0030] The auxiliary mechanism includes a cylindrical member 14. A first gear 15 is fixedly installed on the circumferential surface of each cylindrical member 14. The first gears 15 on each cylindrical member 14 are meshed with each other. A stepped member 16 is provided at the upper end of each cylindrical member 14. A motor 21 is embedded and installed inside the spraying device body 11. A feeding unit 12 and a movable electric spray head unit assembly 13 are respectively provided inside the spraying device body 11. The feeding port of the movable electric spray head unit assembly 13 is connected to the feeding port of the spraying device body 11. A second gear 22 is fixedly installed on the output shaft of the motor 21. The second gear 22 is meshed with the first gear 15. By placing the position of the stepped groove 18 on the PRO gas cylinder body 17 towards the position of the stepped member 16, and then when the diameter of the discharge port 19 of the PRO gas cylinder body 17 reaches a matching stage with the diameter of the circumference of the flat-top conical member 28, at this time, the staff can turn on the motor 21, so that the output shaft of the motor 21 drives the second gear 22 to rotate and mesh with the first gear 15, thereby causing one of the first gears 15 to rotate and mesh with the remaining first gears 15, so as to drive each cylindrical member 14 and the PRO gas cylinder body 17 to rotate, thus completing the synchronous processing of multiple PRO gas cylinders, improving work efficiency and practicability.

[0031] An electric push rod 23 is provided at the upper end of the spraying device body 11. Springs 24 are symmetrically and fixedly installed on the output shaft of the electric push rod 23. A square plate 25 is fixedly installed at the lower end of each spring 24. A limit switch 26 is embedded and installed inside the square plate 25. The limit switch 26 is adapted to the output shaft of the electric push rod 23. The button of the limit switch 26 is of the compression reset type. A plurality of rotating disks 27 are rotatably installed at the lower end of the square plate 25. A flat-top conical member 28 is fixedly installed at the lower end of each rotating disk 27. A PRO gas cylinder body 17 is provided between each flat-top conical member 28 and the stepped member 16. A stepped groove 18 and a discharge port 19 are respectively provided inside the PRO gas cylinder body 17. Each stepped groove 18 is adapted to the stepped member 16. Each discharge port 19 is adapted to the flat-top conical member 28. By placing the position of the stepped groove 18 on the PRO gas cylinder body 17 to be processed towards the position of the stepped member 16 and then turning on the electric push rod 23, the output shaft of the electric push rod 23 drives the square plate 25 to descend together through the spring 24. When the diameter of the discharge port 19 reaches a matching stage with the diameter of the circumference of the flat-top conical member 28, at this time, the flat-top conical member 28 will be stuck at the discharge port 19. At the same time, the continuous downward pressure of the output shaft of the electric push rod 23 will cause the spring 24 to stretch. At the same time, the spring 24 will contact the limit switch 26, so that the limit switch 26 emits a signal to stop the electric push rod 23 in time, thus completing automatic stop, further facilitating the operation of the staff and improving portability.

[0032] Working principle:

[0033] In the first step, when the workpiece needs to be processed, the staff can first place the position of the step groove 18 on the PRO gas cylinder body 17 to be processed toward the position of the step piece 16 and place it. After each step piece 16 is filled with workpieces, the staff can turn on the electric push rod 23 to make the output shaft of the electric push rod 23 drop, so that the output shaft of the electric push rod 23 drives the square plate 25 to drop together through the spring 24. At this time, the flat-top cone 28 will enter the inside of the discharge port 19. When the diameter of the discharge port 19 is equal to the square plate 25, the flat-top cone 28 will enter the inside of the discharge port 19. When the diameter of the circumference of the top cone 28 reaches a matching stage, the flat-top cone 28 will be stuck at the discharge port 19, and at the same time, the continued downward pressure of the output shaft of the electric push rod 23 will stretch the spring 24, and at the same time, the spring 24 will contact the limit switch 26, thereby causing the limit switch 26 (the limit switch 26, the electric push rod 23, the motor 21, the movable electric nozzle unit assembly 13 and the feeding unit 12 are all controlled by the PLC controller) to send a signal to stop the electric push rod 23 in time;

[0034] In the second step, the staff can then turn on the motor 21, so that the output shaft of the motor 21 drives the second gear 22 to rotate and mesh with the first gear 15, thereby causing one of the first gears 15 to rotate, and driving the PRO gas cylinder body 17 to rotate. Then the staff can turn on the feeding unit 12 and the movable electric spray head unit assembly 13, so that the paint of the feeding unit 12 is transported to the inside of the movable electric spray head unit assembly 13, and the movable electric spray head unit assembly 13 (the movable electric spray head unit assembly 13 is an existing structure, mainly composed of an atomizing nozzle and a screw vertical lift) will spray the paint, and at the same time move up and down to evenly spray the PRO gas cylinder body 17.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
