[0001] This utility model relates to the field of spraying equipment technology, and in particular to a spraying device for uniform spraying. Background Technology

[0002] Powder coating equipment is suitable for surface powder coating of workpieces made of metal, plastic and other materials, and is especially suitable for coating production of automotive parts, home appliance shells and other products with high requirements for coating uniformity and quality.

[0003] In existing powder coating processes, the uniformity of the powder coating equipment has always been a key factor affecting the surface quality and protective performance of workpieces. Traditional powder coating equipment has some shortcomings. Existing equipment is relatively unstable when clamping workpieces, has poor positioning effect, and is prone to lateral slippage and tilting of workpieces during spraying, resulting in uneven spraying of workpieces, which affects the full spraying effect and reduces the spraying efficiency. To address these issues, a powder coating equipment with uniform spraying is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a powder coating device that produces uniform powder coating, thereby solving the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: a powder coating device for uniform powder coating, including a spraying machine platform, a spraying box fixedly installed on the upper part of the spraying machine platform, a control panel fixedly installed on the outer wall of the spraying box, a stirring structure fixedly installed on the upper part of the spraying box, two positioning seats symmetrically fixedly installed on the upper part of the spraying machine platform, threaded screws rotatably installed inside the two positioning seats, and connecting seats threadedly connected to the outer wall of the threaded screws, a positioning structure is provided on the upper part of the connecting seat, the positioning structure includes a support platform fixedly installed on the connecting seat, a limit slide rail symmetrically fixedly connected on the upper part of the support platform, and two sets of limit sliders symmetrically slidably connected to the outer wall of the limit slide rail, each set of limit sliders having a mounting seat fixedly installed on its upper end, two guide plates rotatably installed on the outer wall of the mounting seat, with one end of each guide plate rotatably installed on both ends of a rotating plate, and clamping plates fixedly installed on the outer walls of both mounting seats.

[0006] As a preferred embodiment of the above technical solution, one end of the threaded screw is fixedly connected to the output end of the drive motor inside the positioning seat, and two guide sliders are fixedly installed at the bottom of the support platform and are slidably connected to two guide rails respectively. The two guide rails are fixedly installed on the upper part of the spraying machine platform.

[0007] As a preferred embodiment of the above technical solution, a protrusion is fixedly installed on the outer wall of one of the mounting bases, and a cylinder is fixedly connected to one end of the protrusion. The cylinder is fixedly installed on the protrusion, the protrusion is fixedly installed on the support platform, and a placement plate is fixedly installed on the upper end of the support platform, and a workpiece is fixedly placed on the upper end of the placement plate.

[0008] As a preferred embodiment of the above technical solution, the rotating plate is rotatably mounted on the outer wall of the positioning column in the middle and the bottom of the positioning column is fixedly mounted on the support platform. Positioning shafts are fixedly mounted on both sides of the upper end of the rotating plate. The two guide plates are rotatably connected to the two positioning shafts respectively. Anti-slip pads are fixedly attached to the outer walls of the two clamping plates.

[0009] As a preferred embodiment of the above technical solution, the stirring structure includes a conical material cylinder fixedly installed at the upper end of the spray box, a drive module is provided at the upper end of the conical material cylinder, a stirring rod is provided below the drive module, a stirring frame is fixedly installed on the outer wall of the stirring rod, a spiral conveying blade is fixedly installed at the bottom of the stirring rod, and a discharge cylinder is fixedly installed at the bottom of the conical material cylinder.

[0010] As a preferred embodiment of the above technical solution, a discharge pipe is fixedly installed at the bottom of the discharge cylinder and a diversion pipe is fixedly installed at one end of the discharge pipe. A pump body is fixedly connected to one end of the discharge pipe. A limit buckle is fixedly sleeved on the outer wall of the diversion pipe and the upper end of the limit buckle is fixedly installed on the top of the inner side of the spray box. Multiple spray guns are fixedly installed at both ends of the diversion pipe, and the positions of the two sets of spray guns are relative to the positions of the workpieces.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The device of this utility model is equipped with a positioning structure. The mounting seat on the protrusion is driven by the driving cylinder to slide along the direction of the limiting slide rail using the limiting slider. The mounting seat drives the rotating plate on the guide plate to rotate around the positioning column as the center. This causes the other end of the rotating plate to drive another guide plate to move relative to it using the positioning shaft. This causes the two mounting seats to drive the two clamping plates to move relative to each other in a synchronous manner, so as to stably clamp and position the workpiece. This avoids the workpiece positioning effect being poor and causing tilting, which affects the uniform spraying effect. It is beneficial to stably position the workpiece and spray it evenly, thereby improving the spraying processing efficiency of the workpiece.

[0013] 2. This utility model device is equipped with a stirring structure. The stirring frame on the stirring rod is driven by the drive module to rotate along the inner wall of the conical material cylinder to stir the spray coating and prevent clumping, which would cause uneven powder output. At the same time, when the stirring rod rotates, it drives the spiral conveying blades to rotate along the inside of the feeding cylinder to control the powder output. The spray coating is then transported out from the distribution pipe through the driving pump body along the feeding pipe, and then sprayed out by two sets of spray guns. This helps to evenly stir the coating and prevent clumping, while controlling the feeding to avoid pipe blockage and affecting the spraying operation.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5As shown in the figure, this embodiment provides a uniform powder coating device, including a spraying machine base 1, a spraying box 3 fixedly installed on the upper end of the spraying machine base 1, a control panel 2 fixedly installed on the outer wall of the spraying box 3, a stirring structure 5 fixedly installed on the upper end of the spraying box 3, two positioning seats 41 symmetrically fixedly installed on the upper end of the spraying machine base 1, threaded screws 43 rotatably installed inside the two positioning seats 41, and connecting seats 45 threadedly connected to the outer wall of the threaded screws 43, a positioning structure 6 is provided on the upper end of the connecting seat 45, the positioning structure 6 includes a support platform 61 fixedly installed on the connecting seat 45, a limit slide rail 611 symmetrically fixedly connected to the upper end of the support platform 61, and two sets of limit sliders 612 symmetrically slidably connected to the outer wall of the limit slide rail 611, an mounting seat 65 fixedly installed on the upper end of each set of limit sliders 612, two guide plates 692 rotatably installed on the outer wall of the mounting seat 65, and one end of each guide plate 692 rotatably installed on both ends of the rotating plate 69, and a clamping plate 66 fixedly installed on the outer wall of each mounting seat 65.

[0024] like Figures 3 to 4 As shown, one end of the threaded screw 43 is fixedly connected to the output end of the drive motor 4 inside the positioning seat 41. Two guide sliders 44 are fixedly installed at the bottom of the support platform 61, and the guide sliders 44 are slidably connected to two guide rails 42 respectively. The two guide rails 42 are fixedly installed on the upper end of the spraying machine base 1. One of the mounting seats 65 has a protrusion 64 fixedly installed on its outer wall, and one end of the protrusion 64 is fixedly connected to a cylinder 63. The cylinder 63 is fixedly installed on the boss, and the boss is fixedly installed on the support platform 61. A placement plate 62 is fixedly installed on the upper end of the support platform 61, and a workpiece 7 is fixedly placed on the upper end of the placement plate 62. The middle part of the rotating plate 69 is rotatably installed on the outer wall of the positioning column 68, and the bottom of the positioning column 68 is fixedly installed on the support platform 61. Positioning shafts 691 are fixedly installed on both sides of the upper end of the rotating plate 69. The two guide plates 692 are rotatably connected to the two positioning shafts 691 respectively. Anti-slip pads 67 are fixedly attached to the outer walls of the two clamping plates 66.

[0025] By setting guide rail 42 and guide slider 44, the support platform 61 is relatively stable when moving, so that the workpiece 7 can be moved accurately according to the preset spraying area parameters. The movement of the support platform 61 is limited. The mounting seat 65 on the protrusion 64 is driven by the drive cylinder 63 to slide along the direction of the limit rail 612 using the limit slider 611. The mounting seat 65 drives the rotating plate 69 on the guide plate 692 to rotate around the positioning post 68. This causes the other end of the rotating plate 69 to drive another guide plate 692 to move relative to each other using the positioning shaft 691. This causes the two mounting seats 65 to drive the two clamping plates 66 to move relative to each other, so as to stably clamp and position the workpiece 7 and avoid the workpiece 7 from tilting due to poor positioning effect, which would affect the uniform spraying effect.

[0026] like Figure 5As shown, the stirring structure 5 includes a conical material cylinder 51 fixedly installed on the upper end of the spray box 3. A drive module 52 is provided on the upper end of the conical material cylinder 51, and a stirring rod 53 is provided below the drive module 52. A stirring frame 54 is fixedly installed on the outer wall of the stirring rod 53. A spiral conveying blade 55 is fixedly installed at the bottom of the stirring rod 53. A discharge cylinder 56 is fixedly installed at the bottom of the conical material cylinder 51. A discharge pipe is fixedly installed at the bottom of the discharge cylinder 56, and a diversion pipe 58 is fixedly installed at one end of the discharge pipe. A pump body 57 is fixedly connected to one end of the discharge pipe. A limit buckle 581 is fixedly sleeved on the outer wall of the diversion pipe 58, and the upper end of the limit buckle 581 is fixedly installed on the top of the inner side of the spray box 3. Multiple spray guns 59 are fixedly installed at both ends of the diversion pipe 58, and the positions of the two sets of spray guns 59 are opposite to the position of the workpiece 7.

[0027] By setting up a drive module 52, which includes a stirring motor, a worm gear, and a worm wheel, the stirring motor drives the worm gear to rotate, and the worm gear meshes with the worm wheel to rotate. This causes the worm wheel to drive the stirring frame 54 on the stirring rod 53 to rotate and cooperate within the conical material cylinder 51. At the same time, the worm gear and worm wheel are respectively rotated and installed inside the protective cover on the conical material cylinder 51. The design of the spiral conveying blades 55 facilitates the controlled feeding of the spray paint and avoids problems such as pipe blockage during the feeding process. Limit buckles 581 are set on both sides of the outer wall of the diversion pipe 58 to facilitate the limiting support of the two sets of spray guns 59. At the same time, the spray guns 59 adopt a double air duct design, with the inner air duct used to transport powder and the outer air duct providing annular compressed air to form a uniform atomization cone.

[0028] The working principle and process of this utility model are as follows: When it is necessary to spray the workpiece 7, the operator first places the workpiece 7 on the placement plate 62, then connects the external power supply, and drives the cylinder 63 on the drive boss to move the mounting seat 65 on the protrusion 64. The mounting seat 65 is limited by the two bottom limit sliders 612 sliding on the limit slide rail 611, causing the mounting seat 65 to drive the clamping plate 66 to move along the direction of the workpiece 7, causing the guide plate 692 to squeeze the rotating plate 69 to rotate around the positioning post 68 as the center, causing the rotation... When plate 69 rotates, it drives the mounting seat 65 on another guide plate 692 to move relative to each other, which in turn causes the two clamping plates 66 to move relative to each other to stably clamp and position the workpiece 7. Anti-slip pads 67 are provided on the outer wall of the clamping plates 66 to prevent the workpiece 7 from slipping due to poor positioning and affecting the uniformity of spraying. After the workpiece 7 is fixed, the drive motor 4 is turned on to drive the threaded screw 43 to rotate on the positioning seat 41, which causes the threaded screw 43 to drive the workpiece 7 on the connecting seat 45 to move precisely to the spraying position according to the pre-set spraying area parameters.

[0029] At this time, the driving module 52 drives the stirring frame 54 on the stirring rod 53 to rotate along the inner wall of the conical cylinder 51 to stir the spray coating material to prevent clumping and uneven powder output. At the same time, the stirring rod 53 drives the spiral conveying blade 55 to rotate along the inside of the feeding cylinder 56 to control the powder output. The driving pump body 57 drives the spray coating material to be transported out from the diversion pipe 58 along the feeding pipe. Then, it is sprayed out by two sets of spray guns 59 to fully spray the surface of the workpiece 7. Finally, the sprayed workpiece 7 is moved out to proceed to the next process.
