Description

Technical Field

[0001] This utility model relates to the field of spray painting technology, specifically a spray painting device. Background Technology

[0002] With the transformation of the manufacturing industry towards intelligence and greening, and the continuous improvement of consumers' requirements for product appearance quality, the importance of spraying technology in various fields has become increasingly prominent, and higher standards have been put forward for spraying efficiency and coating uniformity. Against this background, the development of innovative spraying equipment is not only the key to meeting the diversified needs of the market, but also an inevitable choice to promote the sustainable development of the manufacturing industry. Therefore, a spraying equipment has emerged.

[0003] However, existing painting equipment has the following problems: First, it relies on external clamping to fix parts, which creates obvious fixed contact areas on the surface of the parts. These areas are blocked by the clamps, resulting in the paint not being able to completely cover the parts during the spraying process, creating blind spots that affect the appearance quality and protective performance of the product. To compensate for the spraying defects in the fixed areas, a manual touch-up process is required, which not only significantly reduces production efficiency but also easily leads to secondary spraying color differences, runs, and other quality hazards, increasing production costs and product defect rates. Second, it is difficult to accurately control the spraying angle and distance when dealing with workpieces of different sizes and shapes, resulting in uneven coating thickness, surface defects, and other problems. Coatings that are not dried in time are easily scratched or contaminated with dust during the transfer process, increasing rework rates and costs.

[0004] To address these issues, we have provided a painting device. Utility Model Content

[0005] The purpose of this invention is to provide a painting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a painting device, comprising an outer frame, an inner support fixing mechanism installed inside the outer frame, and a spray drying mechanism provided above the outer frame.

[0007] Preferably, the internal support fixing mechanism includes a main motor fixedly connected to the bottom surface of the outer frame. The main motor drives a turntable fixedly connected to the top of its rotating shaft to rotate and spray the raw material fixed above the parts. An auxiliary motor is fixedly connected to the top surface of the turntable. The auxiliary motor drives a circular groove fixedly connected to the top of its rotating shaft to rotate. A limit frame is fixedly connected to the top surface of the turntable. Three sets of sliding rods are engaged in the groove of the limit frame. The bottom of the sliding rods is located in the circular groove. When the circular groove rotates, it drives the sliding rods to move in the groove. Under the limit of the limit frame, the three sets of sliding rods are converted into linear motion of internal support or outward expansion to fix the raw material.

[0008] Preferably, the spraying and drying mechanism includes a track fixedly connected to one side of the outer frame, a hydraulic telescopic rod fixedly connected to the bottom surface of the track groove, the hydraulic telescopic rod driving the carrier plate fixedly connected to its top surface to move up and down to adjust the spraying height, and a second hydraulic telescopic rod fixedly connected to one end of the carrier plate, the second hydraulic telescopic rod driving the U-shaped groove fixedly connected to its one end to move stably under the limitation of the bracket fixedly connected to one end of the carrier plate to adjust the spraying distance of the raw material.

[0009] Preferably, a motor is fixedly connected to one side of the U-shaped groove, and the motor shaft passes through the U-shaped groove to drive the spray gun fixedly connected to one end to rotate, thereby adjusting the angle during spraying. A paint bucket is fixedly connected to the top surface of the outer frame, and a paint pump is installed on the top surface of the paint bucket. A hose is fixedly connected to the bottom surface of the paint bucket, passes through the outer frame, and is fixedly connected to the spray gun inside. The paint pump transfers the paint in the paint bucket to the spray gun through the hose and then sprays it out.

[0010] Preferably, a fan is fixedly connected to the top surface of the outer frame, and several fans are installed at the bottom of the fan to perform the drying operation on the raw material after spraying.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model incorporates a circular groove and sliding rods to form an internal support and fixing mechanism. The main motor drives the turntable to rotate, causing the parts placed on it to rotate synchronously, achieving all-round spraying. The auxiliary motor drives the circular groove to rotate, and the curved groove on its inner wall cooperates with the bottom of the sliding rod. Under the constraint of the limiting frame, the rotational motion of the circular groove is converted into the radial linear motion of the three sets of sliding rods. When the circular groove rotates, the sliding rods expand outward along the limiting frame and are fixed by the end support block against the inner wall of the part. When rotating in the opposite direction, the sliding rods retract and release the fixation, ensuring that the parts are stable and do not shake during the spraying process, and that there are no external clamps to block the spraying area, ensuring that there are no dead corners in the spraying of the outer surface of the parts, reducing the manual touch-up process, and avoiding problems such as color difference and drip caused by secondary spraying. 2. This utility model incorporates a spray gun and a fan to form a spray drying mechanism. A hydraulic telescopic rod drives the carrier plate to move up and down, adjusting the height of the spray gun. The second hydraulic telescopic rod pushes the U-shaped groove in a linear motion, adjusting the distance between the spray gun and the raw material. This allows for quick adaptation to the spraying needs of workpieces of different sizes. Combined with the rotation function of the turntable, it achieves all-around spraying without dead angles. The motor drives the spray gun to rotate, allowing for flexible adjustment of the spraying angle. The paint pump on the top of the paint bucket draws paint from the bucket and delivers it to the spray gun through a hose, where it is sprayed evenly. After the spraying device has finished working, the fan starts to generate airflow. This airflow is evenly blown onto the surface of the sprayed raw material by the fan, thereby achieving rapid drying, improving overall production efficiency, and avoiding problems such as pinholes and whitening caused by natural drying.

[0023] Please see Figure 1-6 One embodiment of this utility model is a spray painting device, including an outer frame 1, an inner support fixing mechanism 2 installed inside the outer frame 1, and a spray drying mechanism 3 provided above the outer frame 1.

[0024] Furthermore, the inner support fixing mechanism 2 includes a main motor 201 fixedly connected to the bottom surface of the outer frame 1. The main motor 201 drives a turntable 202 fixedly connected to the top of its rotating shaft to rotate, causing the raw material fixed on the upper part to rotate and be sprayed. An auxiliary motor 203 is fixedly connected to the top surface of the turntable 202. The auxiliary motor 203 drives a circular groove 204 fixedly connected to the top of its rotating shaft to rotate. A limit frame 205 is fixedly connected to the top surface of the turntable 202. Three sets of sliding rods 206 are engaged in the groove of the limit frame 205. The bottom of the sliding rods 206 is located in the groove of the circular groove 204. When the circular groove 204 rotates, it drives the sliding rods 206 to move in its groove, and the three sets of sliding rods 206 are in the limit frame. The limiting mechanism 205 converts the linear motion of the material into an internal support or outward expansion to fix it. The main motor 201 drives the turntable 202 to rotate, causing the parts placed on it to rotate synchronously, achieving all-round spraying. The auxiliary motor 203 drives the circular groove 204 to rotate. Its inner wall curved groove cooperates with the bottom of the slide rod 206. Under the constraint of the limiting frame 205, the rotational motion of the circular groove 204 is converted into the radial linear motion of the three sets of slide rods 206. When the circular groove 204 rotates, the slide rods 206 expand outward along the limiting frame 205 and are fixed by the end support block against the inner wall of the part. When rotating in the opposite direction, the slide rods 206 retract and release the fixation, ensuring that the parts are stable and do not shake during the spraying process, and that there are no external clamps to block the spraying area.

[0025] Furthermore, the spraying and drying mechanism 3 includes a track 301 fixedly connected to one side of the outer frame 1. A hydraulic telescopic rod 302 is fixedly connected to the bottom surface of the groove of the track 301. The hydraulic telescopic rod 302 drives the carrier plate 303 fixedly connected to its top surface to move up and down to adjust the spraying height. A second hydraulic telescopic rod 304 is fixedly connected to one end of the carrier plate 303. Under the limitation of the bracket 305 fixedly connected to one end of the carrier plate 303, the second hydraulic telescopic rod 304 drives the U-shaped groove 306 fixedly connected to one end to move stably to adjust the spraying distance of the raw material. The hydraulic telescopic rod 302 drives the carrier plate 303 to move up and down to adjust the height of the spray gun 308. Under the guidance and limitation of the bracket 305, the second hydraulic telescopic rod 304 pushes the U-shaped groove 306 to move linearly to adjust the distance between the spray gun 308 and the raw material. It can quickly adapt to the spraying needs of workpieces of different sizes. Combined with the rotation function of the turntable 202, it can achieve all-round, dead-angle-free spraying.

[0026] Furthermore, a motor 307 is fixedly connected to one side of the U-shaped groove 306. The rotating shaft of the motor 307 passes through the U-shaped groove 306 and drives the spray gun 308 fixedly connected to one end to rotate, thereby adjusting the spraying angle. A paint bucket 309 is fixedly connected to the top surface of the outer frame 1. A paint pump 310 is installed on the top surface of the paint bucket 309. A hose 311 is fixedly connected to the bottom surface of the paint bucket 309, passing through the outer frame 1 and fixedly connected to the spray gun 308 inside. The paint pump 310 transfers the paint in the paint bucket 309 to the spray gun 308 through the hose 311 and then sprays it out. The rotating shaft of the motor 307 drives the spray gun 308 to rotate in the U-shaped groove 306, thereby achieving flexible adjustment of the spraying angle. The paint pump 310 on the top surface of the paint bucket 309 draws the paint from the bucket and delivers it to the spray gun 308 through the hose 311, thereby spraying it out evenly and achieving multi-angle spraying operation.

[0027] Furthermore, a blower 312 is fixedly connected to the top surface of the outer frame 1, and several fans 313 are installed at the bottom of the blower 312 to perform the drying operation on the raw material after spraying. After the painting device finishes working, the blower 312 starts to generate airflow, which is evenly blown onto the surface of the raw material after spraying by the fans 313, thereby achieving rapid drying and improving overall production efficiency.

[0028] Working principle: The main motor 201 drives the turntable 202 to rotate, causing the parts placed on it to rotate synchronously, achieving all-round spraying. The auxiliary motor 203 drives the circular groove 204 to rotate. The curved groove on its inner wall cooperates with the bottom of the slide bar 206. Under the constraint of the limiting frame 205, the rotational motion of the circular groove 204 is converted into the radial linear motion of the three sets of slide bars 206. When the circular groove 204 rotates, the slide bars 206 expand outward along the limiting frame 205 and are fixed by the end support block against the inner wall of the part. When rotating in the opposite direction, the slide bars 206 retract and release the fixation, ensuring that the parts are stable and do not shake during the spraying process, and that there are no external clamps obstructing the spraying area. The hydraulic telescopic rod 302 drives the carrier plate 303 to move up and down, realizing the adjustment of the height of the spray gun 308. Under the guidance and limitation of the bracket 305, the retractor 304 pushes the U-shaped groove 306 to make linear motion, realizing the adjustment of the distance between the spray gun 308 and the raw material. It can quickly adapt to the spraying needs of workpieces of different sizes. Combined with the rotation function of the turntable 202, it can achieve all-round, dead-angle-free spraying. The motor 307 drives the spray gun 308 to rotate in the U-shaped groove 306, realizing flexible adjustment of the spraying angle. The paint pump 310 on the top of the paint bucket 309 draws the paint in the bucket and delivers it to the spray gun 308 through the hose 311, and then sprays it evenly to realize multi-angle spraying operation. After the painting device finishes working, the fan 312 starts to generate airflow. This airflow is blown evenly to the surface of the sprayed raw material by the fan 313, thereby realizing rapid drying and improving the overall production efficiency.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
