Description

Technical Field

[0001] This utility model relates to the field of steel pipe production technology, specifically to a powder coating equipment for steel pipe support production. Background Technology

[0002] Steel pipe supports are a type of tubular metal structure that is widely used in various aspects of life, such as steel pipe furniture, including barbecue grills, outdoor iron furniture, folding chairs, and folding round tables. These items generally use steel pipes as the support structure. To prevent the steel pipe supports from rusting during use, they often need to be powder-coated on the outside of the steel pipes.

[0003] In the prior art, Chinese Patent Application No. CN202322811491.5 discloses a steel pipe powder coating device, relating to the field of steel pipe technology. The device includes a powder coating box, with a lead screw fixedly connected inside. One end of the lead screw extends to the outside of the powder coating box and is fixedly connected to a handwheel. The end of the lead screw away from the handwheel is threadedly connected to a threaded cylinder. One end of the threaded cylinder is fixedly connected to a limiting plate. Through the coordinated use of the handwheel, lead screw, threaded cylinder, limiting plate, and a first clamp, the device can be adjusted according to the specifications of the steel pipe during use, improving its applicability. Through the coordinated use of a motor, rotating shaft, second clamp, and first clamp, the device can rotate the steel pipe during use, improving the powder coating effect.

[0004] Based on the above information, it can be seen that in the existing powder coating operation, the spray nozzle is generally used to spray the rotating steel pipe. However, in actual use, the spray nozzle sprays out powder material during the powder coating process, and the sprayed powder cannot be completely adhered to the outside of the steel pipe, resulting in some waste. Utility Model Content

[0005] The purpose of this utility model is to provide a powder coating equipment for steel pipe supports to solve the problem of waste caused by inconvenient recycling mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a powder coating equipment for steel pipe supports, comprising a horizontally placed support base, a protective cover fixedly installed on the upper surface of the right end of the support base, a horizontally placed placement platform above the support base, and the placement platform being slidably connected to a guide rail fixedly installed on the upper surface of the support base; the main body of the steel pipe to be powder coated is placed in a groove of a limiting frame fixedly installed on the upper surface of the placement platform, and a recycling mechanism is provided inside the placement platform; a spray nozzle is installed at the top of the inner side of the protective cover, and the spray nozzle is connected to a storage tank fixedly installed on the upper surface of the protective cover via a delivery hose.

[0007] Preferably, the recycling mechanism includes a filter screen installed on the upper surface of the placement platform and a recycling bin fixedly installed on the outer surface of the front side of the protective cover, and the interior of the placement platform is configured as a hollow structure.

[0008] Preferably, a connecting spring is fixedly installed between the upper surface of the filter screen and the upper surface of the placement platform, and two bar magnets are fixedly installed on the upper surface of the filter screen.

[0009] Preferably, the position of the bar magnet corresponds vertically to the position of the cylindrical magnet, and the cylindrical magnet is coaxially fixedly installed with the friction roller, and the friction roller is rotatably connected to the limiting frame.

[0010] Preferably, the friction roller contacts and rubs against the outer surface of the steel pipe body, and a driven worm gear for driving its rotation is fixedly installed at the front end of the friction roller.

[0011] Preferably, the driven worm gear is meshed with the driving worm below, and the driving worm is driven to rotate by a drive motor fixedly mounted on the upper surface of the placement platform.

[0012] Preferably, the nozzle is fixedly connected to the mounting slider, and the mounting slider is slidably connected to an electric slide rail fixedly installed on the inner wall of the top of the protective cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the steel pipe support powder coating production equipment adopts a novel structural design, the specific details of which are as follows:

[0014] 1. The steel pipe body to be powder coated is pushed into the protective cover through the placement platform. Then, the powder in the storage tank is sprayed out through the nozzle inside the protective cover to achieve the purpose of powder coating. During this process, excess powder falls onto the filter screen (the filter screen can filter out the clumps of powder to ensure the recycling quality). Under the action of the air pump, it is transported to the recycling bin through the connecting hose for recycling, reducing material waste.

[0015] Furthermore, during the powder coating process, the mounting slider slides back and forth outside the electric slide rail, thereby using the mounting slider to drive the spray head to move synchronously, expanding the spraying area and improving the overall spraying uniformity.

[0016] 2. During the powder coating process, the drive motor drives the active worm gear to rotate. At this time, the driven worm wheel, which is meshed with the active worm gear, drives the friction roller to rotate. The friction between the friction roller and the steel pipe body drives the steel pipe body to rotate, thereby improving the uniformity of powder adhesion.

[0017] Furthermore, as the friction roller rotates, it drives the cylindrical magnet that is fixed to it to rotate synchronously. The interaction between the cylindrical magnet and the bar magnet causes the filter screen to vibrate up and down (the rotation of the cylindrical magnet continuously switches the magnetism of the surface corresponding to the bar magnet, thus intermittently attracting and repelling the bar magnet), thereby improving the filtration and screening effect.

[0025] 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.

[0026] Example 1: Please refer to Figures 1-3In order to achieve the purpose of powder coating on steel pipes, this embodiment provides the following technical solution, which specifically discloses: a horizontally placed support base 1, a protective cover 2 fixedly installed on the upper right surface of the support base 1, a horizontally placed placement platform 3 above the support base 1, and the placement platform 3 is slidably connected to the guide rail 101 fixedly installed on the upper surface of the support base 1. The main body 4 of the steel pipe to be powder coated is placed in the groove of the limiting frame 8 fixedly installed on the upper surface of the placement platform 3. A spray head 6 is installed at the top inner side of the protective cover 2, and the spray head 6 is connected to the storage tank 5 fixedly installed on the upper surface of the protective cover 2 through the delivery hose 7. The spray head 6 is fixedly connected to the mounting slider 19, and the mounting slider 19 is slidably connected to the electric slide rail 20 fixedly installed on the inner wall of the top of the protective cover 2.

[0027] When using the device, first place the steel pipe body 4 to be powder coated on the placement platform 3. At this time, the steel pipe body 4 is limited in the groove of the limit frame 8 above the placement platform 3. Then, push the placement platform 3 into the protective cover 2 (the placement platform 3 is slidably connected to the guide rail 101 above the support base 1). Then turn on the nozzle 6. At this time, the powder inside the storage tank 5 is transported to the nozzle 6 through the delivery hose 7 under the action of the pump and sprayed out, thereby spraying the powder onto the surface of the steel pipe body 4. During this process, the mounting slider 19 slides outside the electric slide rail 20, driving the nozzle 6 to move back and forth left and right, expanding the overall spraying range.

[0028] Example 2: Please refer to Figures 3-4 In order to achieve the purpose of recycling excess powder, this embodiment provides the following technical solution, which specifically discloses that: a recycling mechanism is set inside the placement platform 3, the recycling mechanism includes a filter screen 10 installed on the upper surface of the placement platform 3 and a recycling box 11 fixedly installed on the outer surface of the front side of the protective cover 2, and the interior of the placement platform 3 is set as a hollow structure.

[0029] Excess powder from the spraying falls onto the filter screen 10. At the same time, the pump body connected to the connecting hose 12 is turned on to generate negative pressure, which draws the powder above the filter screen 10 into the recycling box 11 through the connecting hose 12 to achieve the purpose of recycling. During this process, the filter screen 10 filters out the clumps of powder, ensuring the quality of the recycled powder.

[0030] Example 3: Please refer to Figures 5-6In order to improve the uniformity of spraying, this embodiment provides the following technical solution, specifically: a connecting spring 18 is fixedly installed between the upper surface of the filter screen 10 and the upper surface of the placement platform 3, and two bar magnets 17 are fixedly installed on the upper surface of the filter screen 10. The positions of the bar magnets 17 correspond vertically to the positions of the cylindrical magnets 16, and the cylindrical magnets 16 are coaxially fixedly installed with the friction roller 9. The friction roller 9 is rotatably connected to the limiting frame 8. The friction roller 9 contacts and rubs with the outer surface of the steel pipe body 4, and a driven worm gear 13 for driving its rotation is fixedly installed at the front end of the friction roller 9. The driven worm gear 14 is meshed and connected below the driven worm gear 13, and the driven worm gear 14 is driven to rotate by a drive motor 15 fixedly installed on the upper surface of the placement platform 3.

[0031] During the spraying process, the drive motor 15 on the upper surface of the placement platform 3 is turned on, and the drive motor 15 drives the active worm gear 14 to rotate. At this time, the driven worm wheel 13 connected to the active worm gear 14 drives the friction roller 9 to rotate. Under the friction force between the friction roller 9 and the steel pipe body 4, the steel pipe body 4 is driven to rotate, which improves the uniformity of powder adhesion. During the rotation of the friction roller 9, the cylindrical magnet 16 fixedly installed with it is driven to rotate. When the cylindrical magnet 16 rotates, it continuously switches the magnetic pole corresponding to the bar magnet 17, thereby realizing the intermittent adsorption and repulsion of the bar magnet 17. The bar magnet 17 drives the filter screen 10 to move synchronously. With the help of the connecting spring 18, the filter screen 10 vibrates up and down, which improves the filtration and screening speed of the filter screen 10 for powder.
