Description

Technical Field

[0001] This invention relates to the field of gas cylinder sandblasting and rust removal technology, specifically to a sandblasting and rust removal device for the inner and outer walls of gas cylinders. Background Technology

[0002] As special pressure-bearing equipment, gas cylinders inevitably experience rust on their inner and outer walls during transportation and use. To ensure safe operation, regular inspection and maintenance of gas cylinders are essential. Sandblasting is a crucial step in removing rust and preparing the cylinders for subsequent inspection and coating.

[0003] Currently, there are various sandblasting devices available on the market for rust removal from gas cylinders. These devices can achieve automated sandblasting treatment of the cylinder surface to a certain extent. However, in actual production applications, most existing devices focus on automating the sandblasting process itself, such as the rotation of the gas cylinder and the movement of the nozzle.

[0004] In the entire operation process, the loading, processing, and unloading of gas cylinders are often independent steps, lacking effective mechanical linkage and coordination. After the operator places a gas cylinder at the processing station, the equipment starts working; after completion, the equipment stops, waiting for the operator to unload the processed cylinder before loading the next one. This step-by-step, intermittent operation mode results in long idle waiting times during cylinder changes, reducing the overall utilization rate of the equipment and the continuity of the production line, thus affecting the overall rust removal efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a sandblasting rust removal device for the inner and outer walls of gas cylinders. This device solves the problems of existing gas cylinder sandblasting rust removal devices where the gas cylinder loading, processing, and unloading processes are independent, lack effective mechanical linkage and connection, and adopt a step-by-step, intermittent operation mode, resulting in long idle waiting time during equipment material changeover, low overall utilization rate and production continuity, and affecting overall rust removal efficiency.

[0010] Preferably, both the second and third rotating rods are provided with synchronous pulleys at their left ends, and the outer walls of the two synchronous pulleys are connected by a synchronous belt.

[0011] Preferably, a guide rod one is fixedly connected to the inner wall of the front support frame, and the outer wall of the guide rod one is slidably connected to the inner wall of the movable frame one. A guide rod two is fixedly connected to the front side of the top end of the bottom rod, and the outer wall of the guide rod two is slidably connected to the inner wall of the tray.

[0012] Preferably, one end of the first connecting rod is rotatably connected to the rear end of the first movable frame, and the other end of the first connecting rod is rotatably connected to the right end of the bottom rod. One end of the second connecting rod is fixedly connected to the outer wall of the first rotating rod, and the other end of the second connecting rod is fixedly connected to the outer wall of the baffle.

[0013] Preferably, a motor is mounted on the rear right side of the movable frame via a fixed frame, and the drive end of the motor is connected to a threaded rod.

[0015] Preferably, the toothed plate and the gear are on the same horizontal line. After the gear moves backward and meshes with the toothed plate, it rotates 90°. The top of the base plate is provided with a slide rail for moving the first and second moving frames. The bottom end of the arc plate is arc-shaped. The baffle and the support plate together form an L shape.

[0016] Working Principle: Place the gas cylinder requiring rust removal onto the clamping rod. Then, start motor one, which drives the moving frame one and the clamping rod to move towards the left-side arc-shaped plate via a threaded rod. The gas cylinder nozzle on the clamping rod passes through the spray nozzle two. When the gas cylinder reaches the top of the arc-shaped plate, the clamping rod places the cylinder onto the plate. During the movement of moving frame one, connecting rod one drives moving frame two backward. When moving frame two moves backward, the gear and toothed plate mesh, causing rotating rod one to rotate 90°. This, in turn, causes the baffle and support plate to rotate around rotating rod one. After the gas cylinder is placed, start motor one, which drives moving frame one to move to the right. This, through the aforementioned linkage, returns the baffle and support plate to their original positions. Once moving frame one returns to its original position, place another gas cylinder requiring rust removal onto the plate. The gas cylinder to be derusted is placed on the clamping rod. At this time, the fixing rod at the front end of the support plate abuts against the bottom rear end of the arc plate. Then, the second motor is started, driving the second and third rotating rods to rotate simultaneously. This, in turn, drives the gas cylinder to rotate via the rollers. The second electric push rod drives the second nozzle to extend into the gas cylinder, and the first nozzle moves via the electric slide rail and sliding sleeve. Through the camera on the outer wall of the second nozzle, the second and first nozzles are moved to the end of the gas cylinder. The sand material in the storage box is transferred to the first and second nozzles through the conveying pipe via the control panel, and the inner and outer walls of the gas cylinder are sandblasted to remove rust. After the sandblasting is completed, the camera performs a 360° scan of the inner and outer walls of the gas cylinder. The AI ​​vision algorithm compares the surface texture in real time to determine whether it meets the Sa2.5 standard. If any missed areas or rust residue are found, additional spraying is performed using nozzle two and nozzle one. Once the target is met, motor two is turned off to stop the rotation of the gas cylinder. Then, electric push rod one pushes rotating rod two upwards, causing the arc plate to rotate around the hinge on the top side of the rear end of the base frame. During the rotation, because the fixed rod abuts against the bottom side of the rear end of the arc plate, the rotating arc plate will press the arc plate downwards, causing the support plate to move downwards and compressing the spring, causing the gas cylinder on the arc plate to roll onto the support plate. Then, electric push rod one returns the arc plate to its original position. After that, motor one is started to move another gas cylinder that needs sandblasting and rust removal from the clamping rod to the arc plate, and moves the moving frame two backwards. Through gears and toothed plates, the baffle and support plate rotate 90°, unloading the gas cylinder from the support plate.

[0017] This invention provides a sandblasting rust removal device for the inner and outer walls of gas cylinders. It has the following beneficial effects: 1. This invention mechanically links the feeding and conveying action of the gas cylinder with the flipping action of the unloading platform by setting up a linkage structure of a first movable frame, a first connecting rod, a second movable frame, gears and toothed plates. This realizes the synchronous operation of feeding and unloading preparation work, simplifies the operation process, and improves the overall level of automation and work efficiency.

[0018] 2. This invention utilizes an electric push rod to lift an arc-shaped plate, and with the help of a fixed rod that cleverly abuts against the bottom of the arc-shaped plate, it achieves the automatic and stable transfer of processed gas cylinders from the processing platform to a pallet. This design avoids the need for manual handling and reduces labor intensity.

[0019] 3. This invention, through the separate arrangement of inner and outer wall nozzles and the precise drive of the electric slide rail and electric push rod, can achieve comprehensive sandblasting and rust removal of the inner and outer surfaces of the gas cylinder. Furthermore, the integrated camera in the nozzle, combined with a visual algorithm, enables real-time monitoring and re-spraying of rust removal quality, ensuring the uniformity and reliability of the treatment effect and achieving a high cleaning standard.

[0020] 4. This invention ensures the stability and accuracy of key components during movement by providing guide rods for both the movable frame and the support plate. Simultaneously, the use of a synchronous belt to connect two rotating rollers provides stable and synchronized rotational drive for the gas cylinder, laying a solid structural foundation for achieving a uniform sandblasting effect.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example: Please refer to Figures 1 to 5 This invention provides a sandblasting rust removal device for the inner and outer walls of gas cylinders, which aims to solve the problems of low automation, cumbersome loading and unloading processes, and poor coordination between various actions in the existing sandblasting rust removal devices for the inner and outer walls of gas cylinders.

[0025] like Figure 1 and Figure 2 As shown, the sandblasting rust removal device for the inner and outer walls of the gas cylinder includes a base plate 1, which serves as the installation platform for the entire device. Multiple functional components responsible for conveying, processing, and unloading the gas cylinder are integrated at its top. Two support frames 2 are fixedly connected to the right side of the top of the base plate 1, forming the framework for the conveying mechanism. A slide rail is provided along the length of the rear side of the top of the base plate 1, and a movable frame 9 is slidably connected to the slide rail. A storage box 32 is fixedly connected to the front side of the top of the base plate 1 for storing and supplying the sand required for the sandblasting operation. A base frame 21 is fixedly connected to the middle of the top of the base plate 1 to support the rotating processing platform of the gas cylinder. A fixing plate 41 is fixedly connected to the left side of the top of the base plate 1 for installing the sandblasting components for processing the inside of the gas cylinder. A toothed plate 12 is also fixedly connected to the rear side of the top of the base plate 1, serving as part of the linkage mechanism. A control panel 40 is fixedly connected to the left side of the front of the base plate 1 for centralized control of the equipment by the operator.

[0026] The conveying mechanism is built on support frame 2. A threaded rod 3 is rotatably connected to the inner wall of the rear support frame 2. A movable frame 4 is threadedly connected to the threaded rod 3 through its internal threaded sleeve. A motor 6 is mounted on the rear right end of the movable frame 4 via a fixed frame. The drive end of the motor 6 is fixedly connected to the end of the threaded rod 3, driving the threaded rod 3 to rotate, thereby enabling the movable frame 4 to perform precise linear reciprocating motion along the axial direction of the threaded rod 3. To ensure the smoothness and guidance of the movable frame 4's movement, a guide rod 7 is fixedly connected to the inner wall of the front support frame 2, with the outer wall of the guide rod 7 slidingly passing through the inner wall of the movable frame 4. Two parallel clamping rods 5 are fixedly connected to the top left end of the movable frame 4 for clamping the gas cylinder to be processed.

[0027] The core linkage structure of this device is achieved by connecting movable frame 4 and movable frame 9. The rear end of movable frame 4 is connected to the structure of movable frame 9 via a connecting rod 8. Specifically, one end of connecting rod 8 is rotatably connected to the rear end of movable frame 4, and the other end is rotatably connected to the right end of the base rod 15, which forms part of movable frame 9. This connection method allows movable frame 4 to drive movable frame 9 to slide on the slide rail at the top of the base plate 1 via connecting rod 8 when it is moving linearly, thus realizing the mechanical linkage between the loading action and the unloading preparation action.

[0028] The unloading mechanism of this device is integrated on the movable frame 2 9, and through its cooperation with the toothed plate 12 fixed on the base plate 1, it achieves precise linkage with the loading action. Please refer to the following for details. Figure 1 and Figure 2 A rotating rod 10 is rotatably connected between the inner walls of the movable frame 2 9, and a gear 11 is fixedly connected to the middle of the outer wall of the rotating rod 10. The gear 11 and the toothed plate 12 fixed to the rear side of the base plate 1 are on the same horizontal line. When the movable frame 2 9 moves backward under the drive of the connecting rod 8, the gear 11 meshes with the toothed plate 12. The rolling of the gear 11 on the toothed plate 12 converts the linear motion of the movable frame 2 9 into the rotational motion of the rotating rod 10. Its transmission ratio is precisely designed so that after the movable frame 2 9 completes one stroke, the rotating rod 10 rotates exactly 90°.

[0029] Both sides of the outer wall of the rotating rod 10 are connected to baffles 14 via connecting rods 2 13. One end of connecting rod 2 13 is fixedly connected to the outer wall of the rotating rod 10, and the other end is fixedly connected to the outer wall of the baffle 14, forming a rigid connection. This allows the rotational motion of the rotating rod 10 to be directly transmitted to the baffles 14, causing them to rotate synchronously. The inner walls of the two baffles 14 are connected to a support plate 16 via an elastic component. The baffles 14 and the support plate 16 together form an L-shaped structure for receiving and unloading gas cylinders. A fixing rod 20 is also fixedly connected to the front end of the support plate 16 for subsequent linkage with the gas cylinder rotation processing platform.

[0030] Please refer to Figure 1 The structure of the elastic component is described below. The component includes a slider 17 located on the inner wall of the baffle 14 and capable of sliding up and down. The bottom end of the slider 17 is fixedly connected to the support plate 16. A spring 18 connects the bottom rod 15, which connects the lower parts of the two baffles 14, to the slider 17. Specifically, one end of the spring 18 is connected to the slider 17, and the other end is connected to the bottom rod 15. To ensure that the support plate 16 moves smoothly up and down under the action of the spring 18, a guide rod 19 is fixedly connected to the front of the top end of the bottom rod 15. The outer wall of the guide rod 19 is slidably connected to the inner wall of the support plate 16, providing precise motion guidance. This structure allows the support plate 16 to undergo a cushioned downward pressure relative to the baffles 14 when subjected to external force.

[0031] The sandblasting of the gas cylinders is carried out on a processing platform located on the base frame 21. An arc-shaped plate 22 is rotatably connected to the rear top side of the base frame 21 via a hinge. The bottom end of the arc-shaped plate 22 is rounded to facilitate the placement and rolling of the gas cylinders. Parallel rotating rods 24 and 25 are rotatably connected to the inner wall of the arc-shaped plate 22. Rollers 27 are fixedly connected to the outer walls of both rotating rods. The rollers 27 are rotatably connected to the top of the arc-shaped plate 22 to support and drive the rotation of the gas cylinders. To increase the friction between the rollers 27 and the outer wall of the gas cylinder, ensuring stable rotation of the gas cylinders, rubber rings 28 are fixedly connected to the outer walls of the rollers 27.

[0032] The rotational driving force of the gas cylinder is provided by motor 23, which is installed at the left end of the arc plate 22. The driving end of motor 23 is fixedly connected to the end of rotating rod 24. To achieve synchronous rotation of the two rollers 27, synchronous pulleys are provided at the left ends of rotating rod 24 and rotating rod 25. The outer walls of the two synchronous pulleys are connected by synchronous belt 26 to form a synchronous transmission system.

[0033] This device is equipped with internal and external wall sandblasting systems. The external wall sandblasting system includes a moving component located at the top of the storage tank 32, consisting of an electric slide rail 33 and a sliding sleeve 34 slidably connected to its top. The bottom end of nozzle 35 is fixedly connected to the sliding sleeve 34 and, driven by the electric slide rail 33, can reciprocate along the cylinder axis to sandblast the outer wall of the cylinder. The internal wall sandblasting system is mounted on a fixed plate 41. The right end of the fixed plate 41 is connected to a pipe 38 via an electric push rod 37. The right end of the pipe 38 is rotatably connected to nozzle 39. By extending or retracting the electric push rod 37, nozzle 39 can be precisely inserted into the cylinder. Both nozzles and cameras are installed at the rear end of nozzle 35 and on the outer wall of nozzle 39 for real-time sandblasting operations and quality inspection. Both nozzles are connected to the storage tank 32 via a feed pipe 36 to obtain sand.

[0034] The automatic unloading function of the device is achieved through a lifting assembly. This lifting assembly includes a fixed block 31 located at the rear end of the storage bin 32, with an electric push rod 30 rotatably connected to the rear end of the fixed block 31. A rotating sleeve 29 is fixedly connected to the extended end of the electric push rod 30, and the inner wall of the rotating sleeve 29 is rotatably connected to the outer wall of a rotating rod 24. When the electric push rod 30 extends, it pushes the rotating rod 24 upward, causing the entire arc-shaped plate 22 to flip upward around its rear hinge. During this process, the fixed rod 20, previously in a contact position, with its outer wall abutting the bottom rear end of the arc-shaped plate 22, is subjected to the pressure of the flipped arc-shaped plate 22, thereby pressing the support plate 16 downward, completing the transfer of the gas cylinder from the processing platform to the unloading mechanism. A method for sandblasting rust removal of the inner and outer walls of a gas cylinder includes the following steps: Step 1: Loading and initial positioning of the gas cylinder to be processed: Place the gas cylinder that needs to be derusted horizontally on the two parallel clamping rods 5 on the top left side of the moving frame 4, ensuring that the cylinder axis is consistent with the conveying direction and the cylinder mouth faces the left fixed plate 41.

[0035] Step 2, Lateral Conveying and Linkage Avoidance: Start motor 6 to drive threaded rod 3 to rotate, which in turn drives moving frame 4 to move smoothly to the left processing area along guide rod 7; Linkage action: As the moving frame 4 moves to the left, the connecting rod 8 at the rear end pulls the moving frame 9 to slide backward in sync. Flipping and Avoidance: When the second mobile frame 9 slides, the gear 11 on it meshes with the fixed toothed plate 12 on the rear side of the base plate, converting linear motion into rotational motion, driving the first rotating rod 10 to rotate precisely 90°, and then driving the baffle 14 and the support plate 16 to flip through the second connecting rod 13, making room for the gas cylinder to fall.

[0036] Step 3: Positioning and docking of the gas cylinder with the processing platform: The moving frame 4 continues to move to the left, allowing the gas cylinder nozzle to pass through the nozzle 39, and finally the gas cylinder body sits on the roller 27 at the top of the arc plate 22. At this time, the gas cylinder axis is parallel to the rotating rod 24 and the rotating rod 25.

[0037] Step 4: Conveying Mechanism Reset and Next Round of Material Preparation: After the gas cylinder is positioned, motor 6 reverses, driving the moving frame 4 and clamping rod 5 to reset to the right. During the reset process, connecting rod 8 pushes the moving frame 9 forward, gear 11 disengages from toothed plate 12, and baffle 14 and support plate 16 return to a vertical position under gravity or the reset mechanism. The fixed rod 20 abuts against the rear bottom side of the arc-shaped plate 22, entering the unloading standby posture. The operator can then place the next gas cylinder on the clamping rod 5 on the right, achieving material preparation without stopping the machine.

[0038] Step 5, Gas Cylinder Rotation Drive: Start motor 23 to drive rotating rod 24 to rotate, which in turn drives rotating rod 3 25 to rotate synchronously through synchronous belt 26. This causes the two rollers 27 with rubber rings 28 to drive the gas cylinder to rotate at a constant speed, creating conditions for uniform sandblasting.

[0039] Step 6, Simultaneous sandblasting of inner and outer walls: Inner wall treatment: Activate electric push rod 2 37 to push pipe 38 and nozzle 2 39 into the gas cylinder to the preset depth; External wall treatment: Start the electric slide rail 33 to drive the nozzle 35 to reciprocate linearly along the axis of the gas cylinder; Sandblasting execution: The sand in the storage tank 32 is transported to nozzle one and nozzle two through the conveying pipe 36 to simultaneously sandblast and remove rust from the inner and outer walls of the gas cylinder.

[0040] Step 7, Visual Quality Inspection and Intelligent Re-spraying: Images of the gas cylinder surface are captured using cameras at the rear of nozzle 1 (35) and the outer wall of nozzle 2 (39). AI visual algorithms then compare the surface texture in real time. If the system determines that the Sa2.5 standard has not been met and there are missed sprays or rust residues, the system will automatically adjust the nozzle position for precise respraying. If the system determines that the target has been met, it will automatically proceed to the next step.

[0041] Step 8, Finished Product Unloading and Transfer: Platform Tilting: Turn off motor 23, and the gas cylinder stops rotating. Start the electric push rod 30 to extend and lift the rotating rod 24 upward, causing the arc plate 22 to tilt upward around the rear hinge of the base frame 21; Buffering and receiving: When the arc plate 22 flips, its rear bottom side presses the fixing rod 20, which drives the tray 16 to move down along the inner wall of the baffle 14, compressing the spring 18 to buffer and move down. The processed gas cylinder rolls onto the tray 16. Platform reset: Electric push rod 30 retracts, arc plate 22 returns to flat, and support plate 16 resets under the action of spring 18, carrying the gas cylinder waiting to be unloaded.

[0042] Step Nine, Cyclic Unloading: When the next work cycle starts, i.e., when Step Two is executed again, the moving frame 2 9 moves backward again and drives the pallet 16 to rotate 90°, automatically tilting and unloading the gas cylinders processed in the previous cycle into the collection area. At the same time, the new gas cylinder falls onto the arc plate 22. This completes a full automated cycle.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
