Description

Technical Field

[0001] This utility model relates to the field of metal spraying technology, specifically a rotatable metal surface spraying device. Background Technology

[0002] In the industrial manufacturing field, metal materials are widely used in various industries due to their high strength and high toughness. However, because metal surfaces are susceptible to environmental corrosion, oxidation, and physical wear, equipment life is shortened and performance is reduced. Therefore, metal workpieces are generally coated to improve their corrosion resistance, wear resistance, and aesthetics.

[0003] Currently, existing methods for surface coating of metal parts typically involve manual spraying. First, the metal parts are suspended using hooks, and then workers use spray guns to coat them. However, this method is inefficient and unsuitable for large-scale production. To overcome these shortcomings, existing technology (Chinese patent application number 202420800801.5, application date 2024-04-17) describes a surface coating device for automotive parts production. Through the coordinated arrangement of a motor, a first rotating rod, a drive gear, a driven gear, and a second rotating rod, the device rotates the workpiece suspended on the hook, allowing the spray head to evenly coat multiple metal parts, thereby improving coating efficiency. The device works by pulling down the hook to separate one end from the fixed block, creating a notch. The metal part is then suspended on the hook and released, causing the spring to extend and reset the hook, closing the notch. This prevents the metal part from detaching during rotation and adjustment. However, in actual operation, the device uses a single driving gear to power multiple driven gears, placing high demands on the motor's driving force and the strength of the rotating rod. Over time, this increases motor wear and axial wear on the rotating rod, leading to higher maintenance costs. Furthermore, hooking and unhooking the metal part requires manual pulling of each hook sequentially to compress the spring and expose the notch, resulting in high labor intensity and low work efficiency.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing equipment. Therefore, we have proposed a rotatable metal surface spraying device that can effectively solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a rotatable metal surface spraying device to solve the problems mentioned in the background art. Long-term operation of the aforementioned spraying device will aggravate motor wear and axial wear of the rotating rod, thereby increasing maintenance costs. Furthermore, when hooking and unhooking metal parts, it is necessary to manually pull each hook in turn to expose the notch of the compression spring, which results in high labor intensity and low work efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rotatable metal surface spraying device, including a support platform, a mounting frame fixedly welded to the top of the support platform, and a spraying mechanism movably mounted on the top of the mounting frame via a lifting mechanism.

[0007] The mounting bracket has an integrally formed fixed shell on its top inner wall. Inside the fixed shell, multiple rotating shafts are limited to rotate by bearings. The rotating shafts are evenly and horizontally arranged and correspond one-to-one with the nozzles of the spraying mechanism. The bottom end of each rotating shaft extends through to the outside of the fixed shell and is fixedly connected to a hook bracket. Inside the fixed shell, a drive rotation assembly is provided to drive the multiple rotating shafts to rotate synchronously.

[0008] The hook frame has an n-shaped structure, and the bottom of the front vertical rod has an inwardly protruding temporary hanging part. There is a gap between the temporary hanging part and the rear vertical rod of the hook frame. The bottom of the rear vertical rod of the hook frame is slidably connected to a sliding rod, and the rear end of the mounting frame is provided with a synchronous push-pull assembly to drive multiple sliding rods to slide synchronously.

[0009] Preferably, the drive rotation assembly includes worm gears fixedly connected to the outer wall of each shaft, a worm is rotatably connected between the two sides of the fixed housing, and the worm is driven by a motor mounted on the outer wall of the mounting frame, and each worm gear meshes with one end of the worm.

[0010] Preferably, the synchronous push-pull assembly includes sliding magnetic blocks fixedly connected to both ends of the sliding rod, an electric telescopic rod is installed at the rear end of the mounting frame, and the end of the electric telescopic rod is fixedly connected to the moving plate. Multiple electromagnets are fitted into the front end of the moving plate, and the electromagnets are evenly and horizontally arranged and correspond one-to-one with the sliding rods. When the electromagnets are energized, they will generate an attraction force with the sliding magnetic blocks at the rear end of the corresponding sliding rods.

[0011] Preferably, a fixed magnetic block is fitted into the inner wall of the end of the temporary hanging part, and the fixed magnetic block attracts the sliding magnetic block at the front end of the sliding rod to enhance the stability of the connection between the sliding rod and the end of the temporary hanging part.

[0012] Preferably, the movable plate has protrusions formed at both ends, and the inner sides of both sides of the mounting frame are provided with sliding grooves that match the protrusions, so as to ensure the stability of the movable plate being moved linearly by the electric telescopic rod.

[0013] Preferably, a filter screen is installed in the middle of the support platform to filter the paint dripping during spraying, and a collection box is placed below the filter screen to collect the filtered paint, and a pulley is installed at the bottom of the collection box.

[0014] Preferably, the filter screen is installed inside the mounting frame, and the front end of the support platform has an installation slot for the mounting frame to slide on, and the front end of the mounting frame is also provided with a handle to enable the filter screen to be disassembled and replaced.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This rotatable metal surface spraying device can effectively alleviate motor loss and axial wear of the shaft by setting a drive rotation component to replace the meshing transmission of multiple gears, thereby reducing the frequency of maintenance and reducing maintenance costs. Moreover, by setting the sliding rod and the synchronous push-pull component together, it is not necessary for the staff to pull each hook to compress the spring in turn, which reduces the labor intensity. Furthermore, the concentrated falling of metal parts greatly facilitates collection, thereby improving the overall work efficiency. The specific contents are as follows: (1) By setting a drive rotation component, the meshing transmission of multiple gears can be replaced by the cooperation of worm gear and worm, which can effectively alleviate motor loss and axial wear of the shaft, thereby reducing the frequency of maintenance and reducing maintenance costs.

[0016] By using the sliding rod and synchronous push-pull assembly, when hooking metal parts, you only need to temporarily hook them to the outside of the temporary hanging part through the notch at the bottom of the hook frame. Then, start the electric telescopic rod to drive the moving plate so that each sliding rod moves synchronously to insert with the temporary hanging part, thus sealing the notch with the sliding rod, and then perform rotational spraying.

[0017] By energizing the electromagnet, the magnetic attraction can be used to move the sliding rod to the point where it is disengaged from the temporary hanging part and the gap is exposed, allowing the metal parts to fall automatically from the gap. Finally, the fallen metal parts can be collected all at once. This structure eliminates the need for workers to pull each hook one by one, thus reducing labor intensity. In addition, the metal parts fall in a concentrated manner, making them easy to collect and effectively improving overall work efficiency.

[0018] The filter screen can filter the paint dripping during spraying, and it can also cushion and catch falling metal parts. The collection box can collect the filtered paint to reduce paint waste. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-2 , Figure 4 The present invention provides the following technical solution: a rotatable metal surface spraying device, including a support platform 1, a mounting frame 2 fixedly welded to the top of the support platform 1, and a spraying mechanism 4 movably mounted on the top of the mounting frame 2 through a lifting mechanism 3.

[0023] Furthermore, the top inner wall of the mounting bracket 2 is integrally formed with a fixed shell 5. Inside the fixed shell 5, multiple rotating shafts 6 are limited to rotate by bearings. The rotating shafts 6 are evenly and horizontally arranged and correspond one-to-one with the nozzles of the spraying mechanism 4. The bottom end of the rotating shaft 6 extends through to the outside of the fixed shell 5 and is fixedly connected to a hook bracket 9. The fixed shell 5 is provided with a drive rotation assembly for driving the multiple rotating shafts 6 to rotate synchronously.

[0024] Specifically, the drive rotation assembly includes worm gears 7 fixedly connected to the outer wall of each rotating shaft 6, and worms 8 rotatably connected between the two sides of the fixed housing 5. The worms 8 are driven by a motor mounted on the outer wall of the mounting bracket 2, and each worm gear 7 meshes with one end of the worm 8.

[0025] In use, the metal parts are first hooked onto each hook frame 9 in sequence. Then, the worm gear 8 is driven by the motor to rotate, which in turn drives the meshing worm wheels 7 to rotate synchronously. The rotating shaft 6 rotates accordingly, which in turn drives the hook frames 9 and the hooked metal parts to rotate synchronously. At this time, the lifting mechanism 3 drives the spraying mechanism 4 to descend to the same height as the metal parts, and the water pump is started to pump the paint to the nozzle for spraying. This achieves the effect of rotating and spraying the metal parts. This structure replaces the meshing transmission of multiple gears with the cooperation of worm wheels 7 and worm gear 8, which can effectively reduce motor wear and axial wear of the rotating shaft 6, thereby reducing the frequency of maintenance and reducing maintenance costs.

[0026] Example 2: Based on Example 1, please refer to... Figure 2 , Figures 5-6 The hook frame 9 has an n-shaped structure, and the bottom of the front vertical rod has an inwardly protruding temporary hanging part 10. There is a gap between the temporary hanging part 10 and the rear vertical rod of the hook frame 9. The bottom of the rear vertical rod of the hook frame 9 is slidably connected to a sliding rod 11, and the rear end of the mounting frame 2 is provided with a synchronous push-pull assembly to drive multiple sliding rods 11 to slide synchronously.

[0027] Specifically, the synchronous push-pull assembly includes sliding magnetic blocks 12 fixedly connected to both ends of the sliding rod 11, an electric telescopic rod 14 installed at the rear end of the mounting frame 2, and the end of the electric telescopic rod 14 fixedly connected to the moving plate 15. Multiple electromagnets 16 are fitted into the front end of the moving plate 15, and the electromagnets 16 are evenly and horizontally arranged and correspond one-to-one with the sliding rod 11. When the electromagnet 16 is energized, it will generate an attraction force with the sliding magnetic block 12 at the rear end of the corresponding sliding rod 11.

[0028] The temporary hanging part 10 has a fixed magnetic block 13 fitted into the inner wall of its end. The fixed magnetic block 13 is attracted to the sliding magnetic block 12 at the front end of the sliding rod 11. The attraction between the fixed magnetic block 13 and the front sliding magnetic block 12 enhances the stability of the connection between the sliding rod 11 and the end of the temporary hanging part 10, thereby preventing the metal parts from falling off the notch during the rotation and spraying process of the hook frame 9. It should be noted that the attraction force between the fixed magnetic block 13 and the sliding magnetic block 12 must be less than the attraction force between the electromagnet 16 and the sliding magnetic block 12 after the electromagnet is energized, so that the electromagnet 16 can drive the sliding rod 11 to move backward after being energized, so as to achieve the smooth removal of the metal parts.

[0029] Furthermore, the two ends of the movable plate 15 are formed with protrusions, and the inner sides of both sides of the mounting bracket 2 are provided with sliding grooves that are compatible with the protrusions. By limiting the sliding between the protrusions and the sliding grooves, the stability of the electric telescopic rod 14 pushing the movable plate 15 to move in a straight line can be ensured.

[0030] When hooking metal parts, they are first temporarily hooked onto the outside of the temporary hanging part 10 through the notch at the bottom of the hook frame 9. Then, the electric telescopic rod 14 is activated to move the moving plate 15 forward (at this time, the electromagnet 16 is de-energized), and pushes each sliding rod 11 to move synchronously to the end of the temporary hanging part 10 for insertion, thus sealing the notch with the sliding rod 11. Then, the electric telescopic rod 14 is used to move the moving plate 15 back to its original position to prevent obstruction of the rotation of the hook frame 9. After the spraying is completed and the surface coating is completely dry (the device can...), A drying mechanism is added to accelerate the drying speed of the surface coating. The moving plate 15 is moved closer to the hook frame 9 by the electric telescopic rod 14, and each electromagnet 16 is energized. The attraction between the electromagnet 16 and the sliding magnetic block 12 will drive the sliding rod 11 to move backward, so that it is disengaged from the insertion of the end of the temporary hanging part 10 and the notch is exposed. In this way, most metal parts will fall off automatically from the notch, and the few metal parts still hanging on the temporary hanging part 10 can be gently pushed to fall off. Finally, the fallen metal parts can be collected all at once.

[0031] In summary, this hook structure eliminates the need for workers to manually pull each hook to compress the spring, thus reducing labor intensity. Furthermore, the metal parts fall off in a concentrated manner, greatly facilitating collection and effectively improving overall work efficiency.

[0032] Example 3: Based on Example 2, please refer to... Figure 1 , Figure 3 A filter screen 17 is installed in the middle of the support platform 1, and a collection box 19 is placed below the filter screen 17. The bottom of the collection box 19 is equipped with casters. The filter screen 17 can filter the paint dripping during spraying, and the filter screen 17 can also buffer and catch falling metal parts. The filtered paint is collected by the collection box 19 to reduce paint waste. The casters at the bottom of the collection box 19 make it easy for workers to move the collection box 19 when it is full of paint.

[0033] Meanwhile, the filter screen 17 is installed inside the mounting frame 18, and the front end of the support platform 1 has an installation slot for the mounting frame 18 to slide on. The front end of the mounting frame 18 is also provided with a handle. By pulling the handle, the mounting frame 18 and the filter screen 17 can be quickly slid out from the front end of the installation slot, so as to realize the disassembly and replacement of the filter screen 17 and prevent the coating from solidifying on the filter screen 17 after long-term use, causing blockage and affecting the filtration efficiency.
