Description

Technical Field

[0001] This utility model relates to the field of uniform powder coating technology for guardrails, specifically a device for uniform powder coating of guardrail surfaces. Background Technology

[0002] Guardrails, as an important safety protection facility, are widely used in residences, highways, commercial areas, and public places, primarily for the protection of personal safety and equipment. Guardrails are ubiquitous in daily life, coming in various types, and the price per meter varies depending on the height. In the manufacturing process of guardrails, powder coating is an indispensable step; it not only enhances the guardrail's aesthetics but also strengthens its corrosion resistance and lifespan.

[0003] However, existing guardrail powder coating equipment has some significant technical shortcomings in practical applications. Specifically, most powder coating equipment often places the guardrail directly in the powder coating area during operation. This method easily leads to uneven powder coating, thus affecting the overall quality and appearance of the guardrail. In addition, although some powder coating equipment uses hooks to fix the guardrail, the guardrail may still wobble during the powder coating process. This wobble not only interferes with the uniformity of powder coating but may also cause unnecessary wear and tear on the powder coating equipment, ultimately affecting the powder coating effect. Utility Model Content

[0004] The purpose of this invention is to provide a device for uniform powder coating of guardrail surfaces to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a uniform powder coating device for a guardrail surface, comprising a processing table, a powder coating device being provided on one side of the processing table, an mounting frame being fixedly provided on the processing table, a rotating component being provided on both the mounting frame and the processing table, and a plug-in mechanism being provided on the rotating component through an adjustment mechanism, the plug-in mechanism being matched with the guardrail body.

[0006] Preferably, in order to facilitate the rotation of the guardrail body and to facilitate the powder coating process with the powder coating device, the rotating component includes a rotating shaft set on the processing table and under the mounting frame. A rotating plate is fixedly provided at the end of the rotating shaft. The two rotating plates are symmetrical about the center of the two rotating shafts. The top of the rotating shaft on the mounting frame is fixedly connected to the motor output end.

[0007] Preferably, in order to facilitate the adjustment of the position between the plug-in mechanism and the guardrail body, and to facilitate the positioning and fixing of guardrail bodies of different specifications and sizes, thereby improving applicability, the adjustment mechanism includes an adjustment groove opened at the end of the rotating plate away from the rotating shaft, an adjustment block is slidably fitted in the adjustment groove, and a fastening bolt is threaded onto the adjustment block.

[0008] Preferably, in order to facilitate the adjustment of the position between the plug-in mechanism and the guardrail body, and to facilitate the positioning and fixing of guardrail bodies of different specifications and sizes, thereby improving applicability, guide blocks are symmetrically provided on both sides of the adjusting block, and guide grooves matching the guide blocks are provided on the inner wall of the adjusting groove.

[0009] Preferably, in order to facilitate the adjustment of the position between the plug-in mechanism and the guardrail body, and to facilitate the positioning and fixing of guardrail bodies of different specifications and sizes, thereby improving applicability, the adjustment mechanism also includes a sleeve connected to the adjustment block. The sleeve is provided with a telescopic rod, and the end of the telescopic rod away from the sleeve is provided with a mounting plate, which is connected to the plug-in mechanism.

[0010] Preferably, in order to facilitate insertion into the inner wall of the guardrail body, avoid contact with the outer surface, not affect the powder coating process, and ensure stable and firm insertion, the insertion mechanism includes an insertion block set on the side wall of the mounting plate. The insertion block matches the guardrail body, and the insertion block is wrapped with a rubber sleeve. The insertion block and the mounting plate are equipped with positioning components.

[0011] Preferably, in order to ensure stability and firmness during insertion, a second limiting and fixing is performed after insertion. The positioning component includes a sliding cavity opened inside the insertion block and the mounting plate. The sliding cavity is symmetrically provided with a dial plate. The two dial plates are connected by a spring. The ends of the two dial plates that are far apart from each other are provided with positioning blocks. The positioning blocks slide out of the insertion block and are provided with rubber pads.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The rotating component design allows the guardrail body to rotate omnidirectionally during the powder coating process. The rotating shaft is driven by a motor, which in turn drives the rotating plate and the guardrail body to rotate, ensuring that the powder coating device can uniformly powder coat all surfaces of the guardrail. This avoids the powder coating dead corners that may occur in traditional powder coating methods. The insertion method of the plug block into the inner wall of the guardrail body avoids direct contact with the outer surface of the guardrail, thus not affecting the powder coating effect. The rubber sleeve wrapped around the plug block and the rubber pad in the positioning component further enhance the stability and firmness of the insertion, effectively preventing the guardrail from shaking or falling off during rotation or powder coating.

[0014] By adjusting the sliding engagement of the adjusting block within the adjusting groove and the relative movement of the sleeve and the telescopic rod, the positional relationship between the insertion mechanism and the guardrail body can be flexibly adjusted, enabling the device to adapt to guardrail bodies of different specifications and sizes. Adjustments can be easily made in both the horizontal and vertical directions, thereby ensuring the accuracy and stability of the insertion. Attached Figure Description

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.

[0021] Please see Figures 1-4This utility model provides an embodiment of a uniform powder coating device for a guardrail surface, including a processing table 11. A powder coating device 13 is installed on one side of the processing table 11. The figure shows a robotic arm and a spray gun, and is a partial illustration of the powder coating device 13. It also includes a powder supply tank, a powder pump and pipeline to transport powder to the spray gun, a powder recovery device and a powder spraying chamber, etc., to facilitate powder coating of the guardrail body 12. This is a relatively mature technology and will not be described in detail here. A mounting frame 14 is fixedly installed on the processing table 11. Both the mounting frame 14 and the processing table 11 are equipped with rotating components. The rotating components are equipped with a plug-in machine through an adjustment mechanism. The structure includes a plug-in mechanism that matches the guardrail body 12. To facilitate the rotation of the guardrail body 12 and the all-round powder coating of the guardrail body 12, the rotating component includes a rotating shaft 22 set on the processing table 11 and under the mounting frame 14. The top end of the rotating shaft 22 on the mounting frame 14 is fixedly connected to the output end of the motor 21. A rotating plate 23 is fixedly provided at the end of the rotating shaft 22. The two rotating plates 23 are symmetrical about the center of the two rotating shafts 22. An adjustment mechanism is provided at the end of the two rotating plates 23 away from the rotating shaft 22. The guardrail body 12 can be plugged and fixed diagonally through the plug-in mechanism on the adjustment mechanism to ensure stability during rotation and powder coating.

[0022] Please see Figures 1-4 To accommodate guardrail bodies 12 of different sizes and specifications, facilitate clamping and fixing, improve applicability, and avoid the dead corners in powder spraying caused by traditional direct placement or the wobbling caused by hooking, ensuring comprehensive and effective powder spraying, the adjustment mechanism includes an adjustment groove 41 located at the end of the rotating plate 23 away from the rotating shaft 22. An adjustment block 43 slides within the adjustment groove 41, and the adjustment block 43 reciprocates within the adjustment groove 41 to adjust the horizontal distance between the insertion block 54 in the insertion mechanism and the guardrail body 12, facilitating insertion and removal operations. A fastening bolt 45 is threaded onto the adjustment block 43, which can be tightened after adjustment to prevent slippage. Alternatively, it can be driven by an electric push rod, allowing the adjustment block 43 to slide within the adjustment groove 41 for automatic adjustment. Guide blocks 44 are symmetrically provided on both sides of the adjustment block 43. The inner wall is provided with a guide groove 42 that matches the guide block 44. The guide block 44 slides in the guide groove 42 and is guided and limited during the adjustment process to ensure stability during movement. The adjustment mechanism also includes a sleeve 32 connected to the adjustment block 43. The sleeve 32 is provided with a telescopic rod 33. The telescopic rod 33 slides up and down in the sleeve 32 to adjust the vertical distance between the plug block 54 and the guardrail body 12, adapting to guardrail bodies 12 of different heights and facilitating plug-in positioning. The telescopic rod 33 and the sleeve 32 can also be fastened with bolts to facilitate fixing after adjustment and prevent slippage. It can also be driven by an electric push rod to make the telescopic rod 33 slide up and down in the sleeve 32 to complete automatic adjustment. The end of the telescopic rod 33 away from the sleeve 32 is provided with a mounting plate 31.

[0023] To facilitate insertion and positioning with the guardrail body 12 without affecting subsequent rotation and powder spraying operations, the mounting plate 31 is connected to the insertion mechanism. The insertion mechanism includes an insertion block 54 set on the side wall of the mounting plate 31. The insertion block 54 matches the guardrail body 12, and the insertion block 54 is wrapped with a rubber sleeve 55 to increase the friction with the inner wall of the guardrail body 12 and ensure the insertion effect. The insertion block 54 and the mounting plate 31 are provided with positioning components. The positioning components include sliding cavities 52 opened inside the insertion block 54 and the mounting plate 31. The sliding cavities 52 are symmetrically slidably provided with levers 51. The two levers 51 are connected by a spring 53. The ends of the two levers 51 that are far apart from each other are provided with positioning blocks 56. The positioning blocks 56 slide out of the insertion block 54 and are provided with rubber pads 57. After insertion, the positioning blocks 56 and rubber pads 57 can be used to further position the insertion, ensuring a stable and firm insertion without affecting subsequent rotation and powder spraying operations.

[0024] Working Principle: In use, the guardrail body 12 is placed between two rotating plates 23, and one end of the bottom guardrail body 12 is aligned with the insertion block 54. By moving the two bottom rotating plates 51, the two rotating plates 51 move closer to each other, and the spring 53 contracts under force to store potential energy. The two positioning blocks 56 enter the sliding cavity 52. ​​Through the insertion of the insertion block 54 into the guardrail body 12, it resets under the action of the potential energy of the spring 53. The positioning block 56 moves out of the sliding cavity 52, and with the cooperation of the rubber pad 57 and the rubber sleeve 55, the bottom is initially positioned and fixed. Then, by adjusting the position of the upper insertion block 54, the telescopic rod 33 slides in the sleeve 32 to adjust the insertion block 54. 4. In the vertical direction, when the guardrail body 12 and the upper plug-in block 54 are at the same level, the positioning block 56 can be retracted into the sliding cavity 52 by pressing the lever 51. Then, the adjusting block 43 slides in the adjusting groove 41. The guide block 44 cooperates with the guide groove 42 to ensure the stability of the sliding. The plug-in block 54 is pushed into the guardrail body 12. Then, the positioning is fixed by the fastening bolt 45 to ensure the stability of the fixation. The powder coating device 13 can spray powder onto the guardrail body 12. After one side is powder coated, the motor 21 works, and the rotating shaft 22 and rotating plate 23 rotate and adjust the guardrail body 12 to facilitate the powder coating process on the next side.
