Description

Technical Field

[0001] This utility model relates to the field of spray coating technology, and in particular to a swing-type automatic spray coating device for spray coating. Background Technology

[0002] Spray coating is an important process in material surface treatment. It involves applying coatings to the surface of a workpiece using specific equipment, giving it protective, decorative, and other functions. Spraying equipment (such as spray guns and shot peening machines) atomizes coatings (paints, powders, etc.) into tiny particles. Through pressure, electrostatic adsorption, and other processes, these particles adhere to the workpiece surface, forming a uniform coating. The process encompasses workpiece pretreatment (cleaning, rust removal), coating preparation, spraying operation (controlling distance, angle, etc.), and curing and drying (natural drying, heat drying, etc.).

[0003] In the modern spray coating industry, automatic spray coating devices are widely used to improve spray coating efficiency and quality. Traditional automatic spray coating devices mostly employ fixed-angle or single-direction spraying methods. When spraying complex-shaped workpieces, this easily leads to spraying dead zones, resulting in uneven coating thickness and affecting the coating effect. Furthermore, some spray coating devices cannot flexibly adjust the spraying range and frequency during the spraying process, making it difficult to meet the needs of workpieces of different sizes and with different spraying process requirements. This not only reduces spray coating efficiency but also wastes paint. Therefore, it is necessary to design a swing-type automatic spray coating device for spray coating processes.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides a swing-type automatic spraying device for spraying processing, which solves the problems of traditional devices having fixed spraying angles and single directions, easy to leave dead corners on complex workpieces, uneven coating, and difficulty in adjusting the range and frequency, resulting in low efficiency and waste of paint.

[0006] The present invention adopts the following technical solution: an automatic oscillating spraying device for spraying processing. It mainly includes a machine base, an oscillating assembly, and a spraying assembly. The oscillating assembly includes a support platform mounted on the side of the machine base, a bracket mounted on the support platform, and two sets of extending rods connected by a connecting rod. The connecting rod has movable sleeves at both ends, and bolts are connected to the movable sleeves. Each set of movable sleeves has a rotating part mounted on its side. The chassis has an outwardly extending circular protrusion, and a fixed shaft is mounted on the protrusion. The surface of the fixed shaft has a first inner groove, and a rotating rod is sleeved in the inner groove of the fixed shaft. A rotating disk is mounted on a bearing at the center of the chassis shaft, and an eccentric shaft is mounted at the eccentric position of the rotating disk. The eccentric shaft has a second inner groove, and a groove adapted to the second inner groove is formed on the rotating rod. The spraying assembly is connected and installed between one end of the two sets of rotating rods.

[0007] Furthermore, the bolt is adapted to pass through and be threaded into the extension rod, while the extension rod has multiple sets of threaded blind holes that are adapted to the bolt.

[0008] Furthermore, a drive unit is installed on the side of the connecting rod. The drive unit includes a storage box installed on the side of the connecting rod. A connecting shaft is installed through a bearing on the storage box. The two ends of the connecting shaft pass through two sets of chassis and are fixedly connected to the corresponding rotating disks. A motor is installed on the side of the connecting rod away from the drive unit. The output end of the motor passes through the connecting rod and the storage box in sequence.

[0009] The motor output end is equipped with a first bevel gear, and the connecting shaft is fitted with a second bevel gear inside the storage box, with the second bevel gear meshing with the first bevel gear.

[0010] Furthermore, a sealing cover is fixedly installed on the storage box by fasteners. A rubber sealing ring is set on the mating surface of the sealing cover and the storage box to form a closed cavity. The sealing cover is made of corrosion-resistant metal sheet with chrome plating on the surface, which can effectively prevent paint droplets generated during the spraying process from entering the interior of the storage box.

[0011] Furthermore, a fixed cover is installed on the machine base, and a columnar material box is installed on the machine base. The material box stores paint. A top plate is connected to the top of the material box by fasteners. A driving component is installed on the top plate. The output end of the driving component passes through the top plate. A stirring shaft is installed at the output end of the driving component. The stirring shaft has stirring blades. A pump body is provided on the surface of the material box.

[0012] Furthermore, the spraying assembly includes a rotating shaft installed between one end of the two sets of rotating rods. Two sets of fixing sleeves are fastened to the rotating shaft by bolts. Spray nozzles are fixedly installed through the fixing sleeves. One end of the two sets of spray nozzles is connected to a storage pipe. One end of the storage pipe is connected to the output port of the pump body through a hose.

[0013] Furthermore, the combination of the fixed sleeve and the nozzle is defined as a spraying section, and multiple spraying sections can be arranged axially on the rotating shaft.

[0014] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0015] An automatic oscillating spraying device for spraying processes utilizes the mechanical transmission design of the oscillating component. When the rotating disc revolves around the chassis axis, the eccentric motion of the eccentric shaft drives the rotating rod to oscillate back and forth around the fixed axis via a groove. This enables the spraying component to achieve a periodic arc-shaped trajectory motion, overcoming the limitations of traditional fixed-angle spraying. It allows for multi-angle coverage of complex curved surfaces and recessed areas, effectively eliminating spraying dead angles and improving coating uniformity and smoothness. The movable sleeve, through bolts and multiple sets of threaded holes on the extension rod, can flexibly adjust and lock its position on the extension rod, thereby changing the initial angle of the rotating rod and precisely adjusting the oscillation range of the spraying component, enabling it to quickly adapt to workpieces of different sizes and shapes.

Detailed Implementation

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1 to 5 As shown, this utility model embodiment provides a swing-type automatic spraying device for spraying processing, including a material storage component 1, a swing component 2 and a spraying component 3;

[0028] The storage assembly 1 includes a machine base 11, and the swing assembly 2 includes a support platform 21 fixedly installed on the side of the machine base 11, and a bracket 22 fixedly installed on the support platform 21. The bracket 22 has a U-shaped structure and has two sets of extension rods (not shown in the figure). The two sets of horizontal extension rods are arranged in parallel and are movably connected by a connecting rod 23. The connecting rod 23 has movable sleeves 24 at both ends, and its inner wall is clearance-fitted with the outer wall of the extension rod, so that the connecting rod 23 can slide along the axial direction of the extension rod.

[0029] Furthermore, a bolt (not shown in the figure) is threadedly connected to the movable sleeve 24. The bolt is adapted to pass through and be threadedly connected to the extension rod. At the same time, multiple sets of threaded blind holes (not shown in the figure) are provided on the extension rod to match the bolt. When the movable sleeve 24 slides to the target position, the end of the bolt is screwed into the corresponding threaded hole by tightening the fastening bolt, thereby achieving the positioning and locking of the movable sleeve 24 and the extension rod.

[0030] A rotating part is installed on each of the two sets of movable sleeves 24. Each set of rotating parts includes a base 25 fixedly installed on the side of the movable sleeve 24. The base 25 has an outwardly extending circular protrusion, and a fixed shaft 26 is fixedly installed on the protrusion. The surface of the fixed shaft 26 has a first inner groove. A rotating rod 28 is sleeved in the inner groove of the fixed shaft 26. A rotating disk 27 is bearing installed at the axial position of the base 25. An eccentric shaft 29 is fixedly installed at the eccentric position of the rotating disk 27. The surface of the eccentric shaft 29 has a second inner groove. A waist groove 210 adapted to the second inner groove of the eccentric shaft 29 is opened on the rotating rod 28. The spraying assembly 3 is connected and installed between one end of the two sets of rotating rods 28.

[0031] When the rotating disk 27 revolves around the axis of the chassis 25, the eccentric shaft 29 moves eccentrically with the rotating disk 27, driving the rotating rod 28 to reciprocate around the fixed shaft 26 via the waist groove 210. Since the rotating disks 27 of the two rotating parts rotate synchronously, and the spraying assembly 3 is connected between the two sets of rotating rods 28, the spraying assembly 3 follows the rotating rod 28 in a periodic arc-shaped oscillation. By adjusting the position of the movable sleeve 24 on the extended rod, the initial angle of the rotating rod 28 can be changed, thereby adjusting the oscillation range of the spraying assembly 3. This oscillating spraying method allows the spray gun to spray the workpiece from multiple angles, effectively eliminating the dead angles caused by traditional fixed-angle spraying and improving coating uniformity.

[0032] Specifically, a drive unit is fixedly installed on the side of the connecting rod 23. The drive unit includes a storage box 212 fixedly installed on the side of the connecting rod 23. A connecting shaft 214 is installed through a bearing on the storage box 212. The two ends of the connecting shaft 214 are respectively fixedly connected to two sets of chassis 25 through the connecting rod 23 and the corresponding rotating disk 27. At the same time, a motor 211 is fixedly installed on the side of the connecting rod 23 away from the drive unit. The output end of the motor 211 passes through the connecting rod 23 and the storage box 212 in sequence.

[0033] The output end of the motor 211 is fixedly installed with a first bevel gear 213, and a second bevel gear 215 is sleeved on the connecting shaft 214 at the position inside the storage box 212. The second bevel gear 215 meshes with the first bevel gear 213 to form a 90-degree transmission structure.

[0034] After the motor 211 starts, the output shaft drives the first bevel gear 213 to rotate, which in turn drives the second bevel gear 215 and the connecting shaft 214 to rotate synchronously through gear meshing. Since both ends of the connecting shaft 214 are fixedly connected to two sets of rotating disks 27, the two sets of rotating disks 27 rotate synchronously and at the same speed. The eccentric shaft 29 of the rotating disk 27 moves in a circular motion with the rotating disk 27, and drives the rotating rod 28 to reciprocate around the fixed shaft 26 through the waist groove 210. Since the two sets of rotating rods 28 swing synchronously, the spraying assembly 3 connected between their free ends swings periodically in an arc shape, realizing multi-angle spraying.

[0035] Specifically, a sealing cover (not shown in the figure) is fixedly installed on the storage box 212 by fasteners. A rubber sealing ring (not shown in the figure) is provided on the mating surface of the sealing cover and the storage box 212 to form a closed cavity. The sealing cover is made of corrosion-resistant metal sheet with chrome plating, which can effectively prevent paint droplets generated during the spraying process from entering the interior of the storage box 212.

[0036] Specifically, a fixed cover 12 is fixedly installed on the machine base 11, and a columnar material box 13 is fixedly installed on the machine base 11. The material box 13 stores paint. A top plate 14 is connected to the top of the material box 13 by fasteners. A driving component 15 is fixedly installed on the top plate 14. The output end of the driving component 15 passes through the top plate 14, and a stirring shaft 16 is fixedly installed at the output end of the driving component 15. The stirring shaft 16 has stirring blades (not shown in the figure). The stirring blades are propeller-shaped or paddle-shaped.

[0037] Meanwhile, a pump body 17 is provided on the surface of the material box 13, and the pump body 17 is adapted to draw out the paint in the material box 13.

[0038] When the equipment starts, the drive unit 15 drives the stirring shaft 16 and stirring blades to rotate, continuously stirring the paint in the material tank 13 to prevent sedimentation or stratification and ensure uniform paint composition. The pump body 17 starts simultaneously, drawing paint from the bottom of the material tank 13 through negative pressure and transporting it to the spraying assembly 3 via pipeline. Driven by the oscillating component 2, the spraying assembly 3 performs periodic arc-shaped oscillations, evenly spraying the paint onto the workpiece surface. The paint flow rate can be precisely controlled by the pump body 17's speed or a regulating valve (not shown in the figure) to adapt to different spraying process requirements. When it is necessary to replace the paint or clean the material tank 13, the fasteners on the top plate 14 can be removed, and the top plate 14, along with the drive unit 15 and stirring shaft 16, can be disassembled as a whole for thorough cleaning of the inside of the material tank 13.

[0039] Specifically, the spraying assembly 3 includes a rotating shaft 31 fixedly installed between one end of two sets of rotating rods 28. Two sets of fixing sleeves 32 are fastened to the rotating shaft 31 by bolts. Spray nozzles 33 are fixedly installed through the fixing sleeves 32. One end of the two sets of spray nozzles 33 is connected to a material storage pipe 34. One end of the material storage pipe 34 is connected to the output port of the pump body 17 through a hose 35.

[0040] Pump body 17 draws paint from material tank 13 and delivers it to hose 35. The paint is then distributed to two sets of spray nozzles 33 via storage pipe 34. When swing assembly 2 drives rotating rod 28 to swing back and forth, rotating shaft 31 and fixed sleeve 32 swing synchronously, causing spray nozzles 33 to move along a preset arc trajectory to achieve full coverage spraying of the workpiece surface. At the same time, by adjusting the position of fixed sleeve 32 on rotating shaft 31, the distance between the two sets of spray nozzles 33 can be changed to accommodate workpieces of different widths.

[0041] Specifically, the fixed sleeve 32 and the nozzle 33 are combined to form a spraying unit. Multiple spraying units can be arranged axially on the rotating shaft 31, so that the number and spacing of the spraying units can be flexibly adjusted according to the workpiece size, shape and spraying process requirements to adapt to different spraying combinations.

[0042] In summary: After the device is started, the drive component 15 in the storage assembly 1 drives the stirring shaft 16 to rotate, continuously stirring the paint in the material box 13 to maintain the uniformity of the paint; the pump body 17 draws out the paint and delivers it to the nozzle 33 through the hose 35 and the storage pipe 34. At the same time, the motor 211 of the drive component 15 drives the first bevel gear 213 to rotate, and through the meshing second bevel gear 215, it causes the connecting shaft 214 to rotate, thereby driving the two sets of rotating disks 27 to rotate synchronously. The eccentric shaft 29 on the rotating disk 27 drives the rotating rod 28 to reciprocate through the waist groove 210, so that the spraying assembly 3 installed between the rotating rods 28 can achieve periodic arc-shaped oscillation. The multiple spraying parts in the spraying assembly 3 can flexibly adjust the number and spacing of the nozzles 33 according to the workpiece size and spraying process requirements to achieve precise paint spraying.

[0043] The modular design of the spraying unit allows for flexible adjustment of the number and spacing of the spray nozzles 33 according to the size, shape, and spraying process requirements of the workpiece, improving the adaptability of the device to different spraying tasks. The oscillating component 2, in conjunction with the eccentric transmission structure, enables the spray nozzles 33 to perform multi-angle oscillating spraying, effectively eliminating spraying dead angles and ensuring uniform coating coverage. The stirring and pumping design of the material storage component 1 avoids paint sedimentation and stratification, and combined with precise flow control, it ensures spraying quality while reducing paint waste. The sealing design and transmission structure of the drive unit ensure stable power transmission and reduce maintenance frequency.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
