[0002] Steel drums, as common storage and transportation containers, are widely used in industries such as chemical, food, and pharmaceutical. To improve the corrosion resistance, rust prevention, and aesthetics of steel drums, their surfaces are usually coated to extend their service life. Especially at the bottom of the steel drum, due to long-term contact with the ground, wear and corrosion are more severe. The outer rim at the bottom often becomes a weak point in the coating wear, easily leading to corrosion and rust. Therefore, a steel drum bottom outer rim repair device is needed. This device can ensure the integrity of the bottom outer rim coating, accurately replenish and repair any coating defects, ensure the durability of the bottom outer rim of the steel drum, prevent the spread of localized corrosion, and improve the overall performance and lifespan of the steel drum.
[0003] Currently, there are various types of steel drum bottom outer ring patching devices on the market. However, these devices are usually only suitable for spraying steel drums of the same size. They are not convenient for flexibly adjusting the spraying spacing according to different specifications of steel drums, which makes it impossible to effectively guarantee the spraying accuracy and uniformity, thus affecting the coating quality and the durability of the steel drum.

[0005] This utility model is achieved by the following technical solution: a steel drum bottom outer ring patching device, including an adjustment mechanism, a body and an auxiliary mechanism, wherein the adjustment mechanism is located inside the body and the auxiliary mechanism is located inside the adjustment mechanism;
[0006] The adjustment mechanism includes a servo motor, the output end of which is fixedly connected to a worm gear.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention features an adjustment mechanism. A servo motor drives a worm gear to rotate, which, through a worm wheel, causes a bidirectional threaded rod to rotate. This drives a moving block to move synchronously inward or outward.

[0019] This invention, by setting an auxiliary mechanism, matches the weight of the fixed block with that of the servo motor, ensuring more stable rotation of the device and reducing swaying that may be caused by an unstable center of gravity during rotation. The baffle plate is used to prevent excessive displacement of the moving block, and the support base provides stable support for the bottom of the steel barrel, enhancing the safety and reliability of the device.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0028] Example:
[0029] Please combine Figure 1-5 The steel drum bottom outer ring patching device of this embodiment includes an adjustment mechanism 1, a body 2 and an auxiliary mechanism 3. The adjustment mechanism 1 is located inside the body 2 and the auxiliary mechanism 3 is located inside the adjustment mechanism 1.
[0030] The adjustment mechanism 1 includes a servo motor 11, the output end of which is fixedly connected to a worm gear 12. A worm wheel 13 meshes with the surface of the worm gear 12. A bidirectional threaded rod 14 is fixedly connected to the inner wall of the worm wheel 13. A moving block 15 is threadedly connected to the surface of the bidirectional threaded rod 14. A long plate 16 is fixedly connected to the surface of the moving block 15. An electric push rod 17 is installed at the lower end of the worm gear 12. A baffle 18 is fixedly connected to the output end of the electric push rod 17. A limit plate 19 is rotatably connected to the surface of the baffle 18. The cooperation between the worm gear 12 and the worm wheel 13 provides a uniform and stable torque, effectively ensuring the stability of the long plate 16 during movement.
[0031] The worm gear 13 is located at the upper end of the worm 12, and the long plate 16 is located at the bottom of the moving block 15.
[0032] The machine body 2 includes a fixed frame 21. A servo motor 22 is fixedly connected to the upper end of the fixed frame 21. A reducer 23 is fixedly connected to the upper end of the servo motor 22. A paint spraying pneumatic slip ring 24 is fixedly connected to the bottom of the fixed frame 21. A fixed plate 25 is fixedly connected to the bottom of the paint spraying pneumatic slip ring 24. A connecting plate 26 is fixedly connected to the bottom of the fixed plate 25. A fixed column 27 is fixedly connected to the inner wall of the long plate 16. A spray gun 28 is fixedly connected to the surface of the fixed column 27. The setting of the reducer 23 can make the power transmission of the servo motor 22 more stable and precise, reduce noise and vibration during operation, and further improve working accuracy.
[0033] Servo motor 11 is located at the front end of fixed plate 25, and the surface of bidirectional threaded rod 14 is rotatably connected to the inner wall of fixed plate 25.
[0034] The long plate 16 is located inside the connecting plate 26. The upper end of the electric push rod 17 is fixedly connected to the bottom of the connecting plate 26, which enhances the stability of the long plate 16 and keeps it parallel to the outer ring of the bottom of the steel barrel during adjustment. This ensures the precise position of the spray gun 28 during spraying and improves the consistency of the spraying.
[0035] The auxiliary mechanism 3 includes a fixed block 31, a baffle plate 32 is fixedly connected to the inner wall of the fixed plate 25, and a support base 33 is provided below the electric push rod 17. The baffle plate 32 can prevent the moving block 15 from exceeding the moving range, ensure the normal operation of the whole device, avoid failure or loss of control due to excessive displacement, and enhance the safety and reliability of the device.
[0036] There are two baffle plates 32, which are symmetrically distributed on the left and right sides with the worm gear 13 as the center. The inner wall of the baffle plate 32 is rotatably connected to the surface of the bidirectional threaded rod 14, and the front end of the fixing block 31 is fixedly connected to the rear end of the fixing plate 25.
[0037] The implementation principle of the steel drum bottom outer ring patching device in this embodiment is as follows: The operator starts the servo motor 11 by connecting an external power source. The servo motor 11 drives the worm gear 12 to rotate. The rotating worm gear 12 drives the bidirectional threaded rod 14 to rotate through the worm wheel 13. This causes the moving block 15 on the bidirectional threaded rod 14 to move synchronously inward or outward. Then, the moving block 15 drives the long plate 16 to move synchronously. The long plate 16 drives the spray gun 28 to move together through the fixed column 27. To adjust the distance between the spray gun 28 and the steel drum, after adjusting the appropriate distance, the operator connects an external power source to start the electric push rod 17. The output end of the electric push rod 17 extends, causing the baffle 18 to descend. Then, the baffle 18 causes the limiting plate 19 to descend as well, allowing the limiting plate 19 to contact the top of the steel drum for positioning and fixation. This ensures that the steel drum remains stable during edge patching of the bottom outer ring, preventing unnecessary shaking. After this, the operator connects an external power source to start the servo motor 22. Upon startup, the reducer 23 converts the high-speed rotation of the servo motor 22 into a lower speed suitable for spraying motion and increases the output torque, thereby ensuring smooth operation of the device. The servo motor 22 drives the spraying pneumatic slip ring 24 to rotate together. The rotating spraying pneumatic slip ring 24 drives the fixed plate 25 and the connecting plate 26 to rotate together. The connecting plate 26 drives the fixed column 27 to rotate, thereby causing the spray gun 28 on the fixed column 27 to rotate. Through the spraying pneumatic slip ring 24, the spray gun 28 can continuously spray paint while rotating. The outer ring at the bottom of the steel drum is sprayed. The fixing block 31 is located at the rear end of the fixing plate 25, and its weight is the same as that of the servo motor 11, so as to ensure that the device can rotate more stably. The baffle plate 32 can prevent excessive displacement of the moving block 15 and can effectively limit it. The support base 33 can provide stable support for the bottom of the steel drum. The entire device can precisely adjust the spacing of the spray gun 28 according to different steel drums. At the same time, it can also ensure the overall stability of the steel drum when spraying it, further improving the actual effect.
[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
