Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically to a multi-angle automatic powder spraying device. Background Technology

[0002] In the field of industrial powder coating, powder coating technology is widely used in industries such as automobile manufacturing, metal surface treatment, and appliance casing coating. Traditional powder coating equipment is mostly fixed in installation, with the spray gun position and angle not adjustable, or only supporting single-dimensional adjustment (such as height adjustment only). This leads to problems such as incomplete coating coverage, significant powder waste, and frequent manual adjustments when dealing with complex-shaped workpieces (such as curved surfaces and irregularly shaped parts) or products of different specifications. In addition, the spray gun spacing of existing equipment is usually fixed, making it difficult to adapt to different coating areas and precision requirements, limiting the versatility and production efficiency of the equipment, and requiring manual hand-held operation of the spray gun if multi-angle powder coating is needed. Therefore, there is an urgent need for an automated powder coating device that can flexibly adjust the height, angle, and spacing of the spray gun to meet diverse industrial powder coating needs. Utility Model Content

[0013] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. In the description of this invention, it should be noted that the terms "left," "right," "front," "rear," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0014] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described in terms of the embodiments and implementation methods.

[0015] The specific embodiments of this utility model are as follows: A multi-angle automatic powder coating device includes a base 7, on which a spraying device 9 is fixedly mounted. The spraying device 9 is connected to a spray gun 6 via a pipeline (existing technology, not shown in the figure and not described in detail). The device is characterized in that the base 7 is connected to a height adjustment component, which is fixed to the base 7. The height adjustment component is connected to an angle adjustment component, which is connected to the height adjustment component via the base 7. This allows for dual adjustment of the spatial position (height) and angle of the spray gun 6. The base 7 serves as a basic support, the spraying device 9 supplies powder to the spray gun 6 via pipeline, and the height adjustment component can move the angle adjustment component and the spray gun 6 up and down. The angle adjustment component can change the orientation angle of the spray gun 6, thus enabling multi-angle spraying. Through the adjustable height and angle design, the spray gun 6 can adapt to spraying requirements at different heights and tilt angles, solving the problem of limited coverage of traditional fixed spraying devices.

[0016] The height adjustment assembly includes a support plate 1, with a linear track 2 fixedly connected to the lower side of the support plate 1. The linear track 2 is fixed on the base 7. The linear track 2 is slidably connected to a movable block 11. One side of the movable block 11 is fixedly connected to a connecting plate 3 by symmetrically arranged bolts. The connecting plate 3 is connected to the angle adjustment assembly. A slider 10 is fixedly connected to one side of the movable block 11. The slider 10 is screwed to a first screw 12. The lower end of the first screw 12 is fixedly connected to the output shaft of a motor 8 fixed inside a motor 8 cavity. The upper end of the first screw 12 is rotatably connected to the support plate 1. The lower end of the first screw 12 is rotatably connected to the motor 8 cavity. The motor 8 cavity is fixed to the base 7.

[0017] Motor 8 drives the first screw 12 to rotate. Since the slider 10 is screwed to the first screw 12, the rotation of the screw 12 is converted into the linear motion of the slider 10. The slider 10 is fixed on the movable block 11. The movable block 11 is slidably connected to the base 7 through the linear track 2. Therefore, the movement of the slider 10 drives the movable block 11 to slide up and down along the linear track 2. The movable block 11 is connected to the angle adjustment component through the connecting plate 3, thereby realizing the height adjustment of the angle adjustment component and the spray gun 6.

[0018] The angle adjustment assembly includes a fixing block 5. One end of the fixing block 5 is fixedly connected to the connecting plate 3. The upper side of the fixing block 5 is rotatably connected to the end of the housing of the electric push rod 22. The telescopic rod end of the electric push rod 22 is rotatably connected to the upper end of the extension arm 20. The extension arm 20 is fixed to one upper end of the straight rod 15. The straight rod 15 is connected to the spray gun 6 through the spray gun 6 spacing adjustment assembly. The other end of the straight rod 15 is fixedly connected to the lower side of the hinge block 13. The hinge block 13 is rotatably connected to the other end of the fixing block 5.

[0019] The outer shell of the electric push rod 22 is rotatably connected to the fixed block 5, and the telescopic rod is rotatably connected to the extension arm 20. The extension arm 20 is fixed on the straight rod 15, and the other end of the straight rod 15 is rotatably connected to the fixed block 5 through the hinge block 13. When the telescopic rod of the electric push rod 22 extends or retracts, it pushes the extension arm 20 to rotate around the hinge block 13, thereby causing the straight rod 15 and the spray gun 6 to swing around the hinge point, so as to realize the angle adjustment (pitch angle) of the spray gun 6 in the vertical plane.

[0020] The spray gun 6 spacing adjustment assembly includes two pairs of second connecting rods 18. Each pair of second connecting rods 18 is rotatably connected to one end of the straight rod 15 on both sides. Each pair of second connecting rods 18 is arranged in parallel. The other end of each pair of second connecting rods 18 is rotatably connected to both ends of the spray gun bracket 19. The spray gun bracket 19 has a spray gun 6 slot. A retaining plate 23 is fixedly arranged on the upper side of the spray gun bracket 19 corresponding to the two sides of the spray gun 6 slot. The retaining plate 23 is made of elastic material and is used to limit the spray gun 6. The spray gun 6 is set in the spray gun 6 slot, and the retaining plate 23 can hold the spray gun 6.

[0021] Two pairs of second connecting rods 18 are respectively connected to the straight rod 15 and the spray gun bracket 19 to form a linkage mechanism. The spray gun bracket 19 has a slot, and the elastic plate 23 locks the spray gun 6 to fix the spray gun 6. When the position of the second connecting rod 18 changes, the spray gun bracket 19 moves accordingly, thereby changing the spacing between the spray guns 6. By adjusting the position of the spray gun bracket 19 through the linkage mechanism, the spacing of multiple spray guns 6 can be flexibly changed according to the width of the workpiece or the spraying range requirements. The spray gun 6 spacing adjustment assembly also includes a moving block 16, which is slidably connected to a groove 21 formed on the straight rod 15. The moving block 16 is screwed to a second screw 14, and the two ends of the second screw 14 are respectively rotatably connected to the straight rod 15. The two ends of the upper side of the moving block 16 are respectively rotatably connected to one end of a first connecting rod 17, and the other end of each first connecting rod 17 is respectively rotatably connected to the middle of the corresponding second connecting rod 18.

[0022] A knob is fixedly connected to one end of the second screw 14.

[0023] When the second screw 14 is rotated, the movable block 16, which is screwed to the screw 12, slides in the groove 21 of the straight rod 15. The movable block 16 is connected to the middle of the second connecting rod 18 through the first connecting rod 17. The sliding of the movable block 16 pushes the first connecting rod 17 to swing, thereby driving the second connecting rod 18 to rotate, so that the spray gun bracket 19 moves and the spacing is adjusted.

[0024] The knob can also be a stepper motor 8. The output shaft of the stepper motor 8 is fixed to the knob. The stepper motor 8 is fixed inside the protective cover. The protective cover fixes the straight rod 15, forming the second screw 14 drive system.

[0025] The method of using this utility model is as follows: In use, the base 7 of the multi-angle automatic powder spraying device is fixed in the powder spraying chamber. The pipeline connecting the spraying equipment 9 and the spray gun 6 is connected to ensure smooth powder delivery. According to production needs, the spray gun 6 is inserted into the slot of the spray gun bracket 19 and fixed by the elastic clamp 23. The motor 8 of the height adjustment component is started. The motor 8 drives the first screw 12 to rotate, which drives the slider 10 and the movable block 11 to slide up and down along the linear track 2, thereby adjusting the spray gun 6 to a suitable height. According to the surface shape of the workpiece, the electric push rod 22 of the angle adjustment component is started. The telescopic rod extends and retracts, pushing the extension arm 20 to rotate around the hinge block 13, which drives the straight rod 15 and the spray gun 6 to adjust. The tilt angle can be precisely adjusted by controlling the extension and retraction of the electric push rod 22 to ensure that the powder is evenly sprayed onto the workpiece surface. If the spacing of the spray gun 6 needs to be adjusted, the knob at one end of the second screw 14 can be manually rotated (or the screw 12 can be driven by the second screw 14 drive system). The rotation of the screw 12 causes the moving block 16 to slide in the slide groove 21 of the straight rod 15. The moving block 16 pushes the second connecting rod 18 to swing through the first connecting rod 17, thereby changing the position of the spray gun bracket 19 and realizing the precise adjustment of the spacing of the spray gun 6. After the adjustment is completed, the knob can be fine-tuned until the optimal spacing is achieved by observing the workpiece size or the spraying effect. After completing the above adjustments, start the spraying equipment 9 and begin the powder spraying operation. During the operation, the status of the spray gun 6, powder flow rate, and spraying effect can be monitored in real time. The height, angle, or spacing can be adjusted again according to actual needs to ensure that the spraying quality meets the standards.
