Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profile spraying, and particularly relates to an environment-friendly aluminum profile hanging spraying device. Background Art

[0002] In the aluminum profile processing technology, it is necessary to perform spraying treatment on the aluminum profile to form a coating layer to improve the performance of the aluminum profile. At the same time, the aluminum profile hanging device can hang and transport the aluminum profile, which can reduce the manpower consumption of manpower in the spraying and handling processes to a certain extent. However, when the existing hanging device sprays the aluminum profile, generally the aluminum profile is hung on the hanging rack and remains stationary, and then spraying is carried out. When it is necessary to spray the aluminum profile at different angles, it is necessary for workers to hold the spraying tool and stand at different positions, which is inconvenient to change the angle of the aluminum profile, resulting in excessive manpower consumption.

[0003] The invention patent with the authorization announcement number CN115569792B discloses a spraying device for aluminum profile production. The device drives the spray gun to reciprocate up and down in the vertical direction through a lifting mechanism to realize the spraying process of the vertically hung aluminum profile. At the same time, during the up and down reciprocating movement of the spray gun, the aluminum profile is intermittently rotated through a connecting mechanism, a rotating cylinder, a gear one, and a gear two, so as to realize the spraying operation on the outer surfaces around the aluminum profile, without the need for cyclic conveying, thus achieving the effect of improving the spraying operation efficiency. However, this device can only perform spraying operations on the outer surfaces around the aluminum profile and cannot perform spraying operations on the top and bottom of the aluminum profile, resulting in the inability to achieve full spraying of the aluminum profile, and the device has a complex structure and high maintenance costs. Summary of the Invention

[0004] The purpose of the present invention is to provide an environment-friendly aluminum profile hanging spraying device. By controlling the lifting and self-rotation of the aluminum profile and simultaneously cooperating with the spray gun to precisely adjust the spraying angle, it can achieve full and dead-angle-free spraying of the aluminum profile, with high spraying efficiency, good spraying effect, simple structure, convenient operation, and low maintenance costs.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions:

[0006] An environment-friendly aluminum profile suspension spraying device, comprising a spraying chamber and a conveying track. The conveying track passes through the spraying chamber, and a plurality of aluminum profile suspension components are arranged at intervals on the conveying track. Each aluminum profile suspension component is connected to the conveying track through a rotation adjustment mechanism. The rotation adjustment mechanism includes a gear disc and a gear disc mounting seat rotatably connected to the gear disc. The gear disc mounting seat is fixed on the conveying track, and the rotation center of the gear disc is rotatably connected to the gear disc mounting seat through a gear disc rotating shaft. The aluminum profile suspension component includes a hanging rod one and a hanging rod two symmetrically arranged on both sides of the axis of the gear disc. The upper ends of the hanging rod one and the hanging rod two are respectively connected to the gear disc through a rotation driving mechanism. An elevation driving mechanism is further provided at the top of the spraying chamber for driving the gear disc to rotate so as to drive the hanging rod one and the hanging rod two to lift alternately. Spray guns are respectively arranged on both sides of the spraying chamber for spraying the aluminum profiles suspended on the hanging rod one and the hanging rod two. Both spray guns are connected to a spray gun support through a spray angle adjustment mechanism.

[0007] By adopting the above technical solution, the aluminum profiles to be sprayed are respectively suspended on the hanging rod one and the hanging rod two in each aluminum profile suspension component. When the aluminum profile suspension component moves to the designated position in the spraying chamber along with the conveying track, the elevation driving mechanism drives the gear disc in the rotation adjustment mechanism to rotate, so that the hanging rod one and the hanging rod two lift alternately, ensuring that the aluminum profiles suspended on the hanging rod one and the hanging rod two can be accurately included within the spraying range of the spray gun whether it is the top, side or bottom. While the gear disc drives the hanging rod one and the hanging rod two to lift alternately, it can also cooperate with the rotation driving mechanism to drive the hanging rod one and the hanging rod two to rotate, so that the outer surfaces of the aluminum profiles suspended on the hanging rod one and the hanging rod two can be evenly sprayed, further ensuring the spraying quality. At the same time, during the operation of the spray gun, its spraying angle is adjusted in real time through the spray angle adjustment mechanism, so as to ensure that the top, side and bottom of the aluminum profile can be evenly and completely covered with the spraying material, truly realizing an all-round and dead-angle-free spraying effect, significantly improving the spraying quality and efficiency. The whole process does not require manual intervention, which not only greatly reduces the operation difficulty, but also significantly reduces the material waste during the spraying process. At the same time, the device has a simple structure and low maintenance cost, meeting the environmental protection requirements.

[0008] The further setting of the present invention is that: the elevation driving mechanism includes an elevation driving motor fixed on the top of the spraying chamber and an elevation driving gear coaxially and internally connected to the output shaft of the elevation driving motor. A rack one meshing with the elevation driving gear is arranged below the elevation driving gear. The rack one is fixed on a slider one slidably matched with a horizontal chute on the top wall of the spraying chamber. A rack two parallel to the rack one is further arranged at the bottom of the slider one. The rack two is used to mesh with the gear discs in each rotation adjustment mechanism in sequence.

[0009] By adopting the above technical solution, when the aluminum profile hanging assembly moves to the specified position in the spraying booth along with the conveying track, the toothed disc in the aluminum profile hanging assembly meshes with the second rack. At this time, the lifting drive motor starts, driving the lifting drive gear to rotate reciprocally in the positive and negative directions at a set frequency, thereby driving the first rack and the second rack to move synchronously and reciprocally along the transverse chute with the slider. During the reciprocating sliding of the second rack, it drives the synchronous reciprocating rotation of the toothed disc, causing the hanging rods I and II connected thereto to reciprocally alternate in lifting. During the reciprocating alternate lifting of the hanging rods I and II, the suspended aluminum profiles are driven to move up and down relative to the spray guns on both sides respectively, enabling the spray guns to accurately cover all surfaces of the aluminum profiles and ensuring uniform and non-missing spraying.

[0010] The further setting of the present invention is that: a longitudinal chute is provided on the toothed disc mounting seat, a second slider is provided in the longitudinal chute and is in sliding fit with it, a compression spring is provided between the bottom of the second slider and the bottom of the longitudinal chute, the toothed disc rotating shaft is fixedly connected to the second slider, and the toothed disc is rotatably connected to the toothed disc rotating shaft.

[0011] The further setting of the present invention is that: the highest point of the pitch circle of the toothed disc is higher than the pitch of the first rack, a chamfer of 30° - 60° is provided on one side of the toothed disc close to the conveying end of the conveying track, and the highest point of the circumference where the chamfer is located on the side close to the conveying end of the conveying track is lower than the pitch height of the second rack.

[0012] By adopting the above technical solution, during the process of the aluminum profile hanging assembly moving to the specified position in the spraying booth along with the conveying track, the chamfer on the side of the toothed disc in the aluminum profile hanging assembly close to the conveying end of the conveying track first contacts the tooth part of the second rack. As the conveying track continues to move, the second rack gradually presses the toothed disc, causing the toothed disc to be under downward pressure and gradually pressing the second slider and the compression spring until the highest point of the pitch circle of the toothed disc is at the same height as the pitch of the second rack. As the conveying track continues to move, the toothed disc gradually moves below the second rack, ensuring that when the aluminum profile hanging assembly moves to the specified position in the spraying booth along with the conveying track, the toothed disc just moves directly below the second rack. At this time, the toothed disc is in close contact with the second rack under the action of the compression spring and remains stably meshed with the second rack during the sliding of the second rack with the first slider, thereby effectively ensuring the reliable transmission between the second rack and the toothed disc.

[0013] A further setting of the present invention is that the rotation driving mechanism includes a sleeve one and a sleeve two sleeved on the upper ends of the first hanging rod and the second hanging rod respectively. The sleeve one and the sleeve two are respectively rotationally connected to a toothed disc through a first rotating shaft and a second rotating shaft. A first gear and a second gear are respectively arranged on the first rotating shaft and the second rotating shaft. The first gear and the second gear are respectively rotationally connected to the first rotating shaft and the second rotating shaft. The first gear and the second gear are respectively meshed with a driven toothed disc coaxially arranged with the toothed disc. The driven toothed disc is fixedly connected to the toothed disc rotating shaft. The upper ends of the first hanging rod and the second hanging rod penetrate through the sleeve one and the sleeve two and are respectively fixedly connected to a first bevel gear and a second bevel gear. The first bevel gear and the second bevel gear are respectively meshed with a third bevel gear and a fourth bevel gear rotationally connected coaxially on the first rotating shaft and the second rotating shaft. The third bevel gear and the fourth bevel gear are respectively connected to the first gear and the second gear through connecting rods.

[0014] By adopting the above technical solution, when the toothed disc rotates, the sleeve one and the sleeve two connected to it through the first rotating shaft and the second rotating shaft respectively rise or fall alternately, thereby driving the first hanging rod and the second hanging rod to rise and fall synchronously. Due to the self-weight of the first hanging rod and the second hanging rod and the weight of the suspended aluminum profiles, the first hanging rod, the second hanging rod and the suspended aluminum profiles will always remain in a vertical state. Since the driven toothed disc is fixedly connected to the initial disc rotating shaft, when the first gear and the second gear rotate relative to the toothed disc rotating shaft with the toothed disc, the driven toothed disc will remain stationary. At this time, the first gear and the second gear meshed with the driven toothed disc will rotate self. When the first gear and the second gear rotate self, they will respectively drive the third bevel gear and the fourth bevel gear to rotate self synchronously through the connecting rods. When the third bevel gear and the fourth bevel gear rotate self, they will drive the first bevel gear and the second bevel gear meshed with them to rotate self synchronously. When the first bevel gear and the second bevel gear rotate self, they will respectively drive the first hanging rod and the second hanging rod fixedly connected to them to rotate self synchronously, so that the first hanging rod and the second hanging rod can rotate horizontally while rising and falling, ensuring that the aluminum profiles can be fully sprayed.

[0015] A further setting of the present invention is that the spray angle adjusting mechanism includes an angle adjusting shaft fixedly connected to the spray gun. The two ends of the angle adjusting shaft are respectively rotationally connected to the spray gun support. The angle adjusting shaft is connected to the lifting driving motor through a synchronous driving mechanism.

[0016] By adopting the above technical solution, when the lifting driving motor rotates, it drives the angle adjusting shaft to rotate through the synchronous driving mechanism. When the angle adjusting shaft rotates, it drives the spray gun fixedly connected to it to rotate, thereby realizing precise adjustment of the spray angle and ensuring that the spray evenly covers the surface of the aluminum profiles.

[0017] A further setting of the present invention is that the synchronous driving mechanism includes a first synchronous pulley fixedly connected to the output shaft of the lifting driving motor and a second synchronous pulley fixedly connected to the angle adjusting shaft. The first synchronous pulley and the second synchronous pulley are driven by a synchronous belt between them.

[0018] By adopting the above technical solution, the angle adjustment shaft is connected to the output shaft of the lifting motor through a synchronous belt, realizing the synchronous movement of the angle adjustment shaft and the lifting drive motor. Through this linkage mechanism, not only can the spraying angle of the spray gun be accurately controlled under the condition of no additional power, improving the spraying efficiency and quality, but also the adjustment of the spraying angle can be synchronized with the lifting movement of the aluminum profiles on the hook one and the hook two, so as to ensure that the spraying angle always matches the height of the aluminum profiles, ensuring uniform spraying on the surface of the aluminum profiles, avoiding the problem of uneven spraying caused by angle deviation, and further improving the production efficiency and product quality.

[0019] A further setting of the present invention is: further comprising a synchronous belt pulley three, the synchronous belt pulley three is rotatably connected to the top of the spraying booth through a support seat, and the synchronous belt includes a synchronous belt one for driving between the synchronous belt pulley one and the synchronous belt pulley three and a synchronous belt two for driving between the synchronous belt pulley two and the synchronous belt pulley three.

[0020] By adopting the above technical solution, when the lifting drive motor rotates, it drives the synchronous belt pulley three to rotate through the synchronous belt pulley one and the synchronous belt one. When the synchronous belt pulley three rotates, it drives the synchronous belt pulley two to rotate through the synchronous belt two. When the synchronous belt pulley two rotates, it drives the angle adjustment shaft to rotate. The rotation of the angle adjustment shaft drives the spray gun to rotate synchronously, thereby realizing the adjustment of the spraying angle. The adjustment process is simple and the operation is convenient.

[0021] A further setting of the present invention is: a sealing cover is provided on the top of the spraying booth, and both the lifting drive mechanism and the synchronous drive mechanism are located inside the sealing cover.

[0022] By adopting the above technical solution, the setting of the sealing cover can effectively reduce the overflow of dust and paint mist during the spraying process, ensure the cleanliness of the operating environment, improve the safety protection level of the operators at the same time, ensure the high efficiency and environmental protection of the spraying operation, and further optimize the production process.

[0023] A further setting of the present invention is: the initial spraying directions of the two spray guns are respectively opposite to the top and bottom of the aluminum profiles on the hanging rod one and the hanging rod two before the gear disc rotates, and the diameters of the circumferences where the movement trajectories of the spraying points of the two spray guns are located during the angle adjustment are equal to the diameters of the circumferences where the movement trajectories of the hanging points of the hanging rod one and the hanging rod two on the gear disc are located when the gear disc rotates.

[0024] By adopting the above technical solution, before spraying, during the process that the aluminum profile hanging assembly moves to the designated position in the spraying room along with the conveying track, the first hanging rod, the second hanging rod and the aluminum profiles hung on the first and second hanging rods maintain balance under their own action. At this time, the first hanging rod, the second hanging rod and the two aluminum profiles are at the same height. At this time, the initial spraying directions of the two spray guns are opposite to the top and bottom of the aluminum profiles on the first and second hanging rods respectively. When the aluminum profile hanging assembly moves to the designated position in the spraying room along with the conveying track, the two spray guns start to spray the aluminum profiles. At this time, the gear disc starts to rotate and drives the aluminum profiles on the first and second hanging rods to rise and fall and rotate respectively. At the same time, the angles of the two spray guns change synchronously with the rising and falling aluminum profiles, ensuring that the aluminum profiles are sprayed in all directions without dead angles. Since the diameter of the circle where the movement trajectories of the spraying points of the two spray guns are located during the angle adjustment process is equal to the diameter of the circle where the movement trajectories of the hanging points of the first and second hanging rods on the gear disc are located when the gear disc rotates, when the two aluminum profiles rise or fall along with the first and second hanging rods and their horizontal distances from the center of the gear disc decrease or increase, the horizontal distance from the spraying point of the spray gun to the center of the gear disc decreases or increases synchronously during the rotation of the spray gun along with the angle adjustment shaft, ensuring that the horizontal distance between the spraying point of the spray gun and the surface of the aluminum profile always remains constant, thereby greatly improving the spraying quality and making the spraying effect present a uniform and beautiful appearance.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. In the present invention, the aluminum profiles to be sprayed are respectively hung on the first hanging rod and the second hanging rod in each aluminum profile hanging assembly. When the aluminum profile hanging assembly moves to the designated position in the spraying room along with the conveying track, the lifting drive mechanism drives the gear disc in the rotation adjustment mechanism to rotate, so that the first hanging rod and the second hanging rod alternately rise and fall, ensuring that the aluminum profiles hung on the first and second hanging rods can be accurately included in the spraying range of the spray gun whether it is the top, side or bottom. While the gear disc drives the first hanging rod and the second hanging rod to alternately rise and fall, it can also cooperate with the rotation drive mechanism to drive the first hanging rod and the second hanging rod to rotate, so that the outer surfaces around the aluminum profiles hung on the first and second hanging rods can also be evenly sprayed, further ensuring the spraying quality. At the same time, during the operation of the spray gun, its spraying angle is adjusted in real time through the spraying angle adjustment mechanism, so as to ensure that the top, side and bottom of the aluminum profile can be evenly and completely covered with the spraying material, realizing a truly all-round and dead-angle-free spraying effect, significantly improving the spraying quality and efficiency. The whole process does not require manual intervention, which not only greatly reduces the operation difficulty, but also significantly reduces the material waste during the spraying process. At the same time, the device has a simple structure, low maintenance cost and meets the environmental protection requirements.

[0027] 2. In the present invention, the angle adjustment shaft is connected to the output shaft of the lifting motor through a synchronous belt to achieve synchronous movement between the angle adjustment shaft and the lifting drive motor. Through this linkage mechanism, not only can the spraying angle of the spray gun be precisely controlled under the condition of no additional power, improving the spraying efficiency and quality, but also the adjustment of the spraying angle can be synchronized with the lifting movement of the aluminum profiles on the hook one and the hook two, thus ensuring that the spraying angle always matches the height of the aluminum profiles, ensuring uniform spraying on the surface of the aluminum profiles, avoiding the problem of uneven spraying caused by angle deviation, and further improving the production efficiency and product quality.

[0028] 3. Before spraying in the present invention, during the process that the aluminum profile hanging assembly moves to the designated position in the spraying room along the conveying track, the hanging rod one, the hanging rod two, and the aluminum profiles hanging on the hanging rod one and the hanging rod two maintain balance under their own action. At this time, the hanging rod one, the hanging rod two, and the two aluminum profiles are at the same height. At this time, the initial spraying directions of the two spray guns are opposite to the top and bottom of the aluminum profiles on the hanging rod one and the hanging rod two respectively. When the aluminum profile hanging assembly moves to the designated position in the spraying room along the conveying track, the two spray guns start to spray the aluminum profiles. At this time, the gear disc starts to rotate and drives the aluminum profiles on the hanging rod one and the hanging rod two to rise and fall and rotate respectively. At the same time, the angles of the two spray guns change synchronously with the rising and falling aluminum profiles, ensuring that the aluminum profiles are sprayed in all directions without dead angles. Since the diameters of the circumferences where the movement trajectories of the spraying points of the two spray guns are located during the angle adjustment process are equal to the diameters of the circumferences where the movement trajectories of the hanging points of the hanging rod one and the hanging rod two on the gear disc are located when the gear disc rotates, when the two aluminum profiles rise or fall with the hanging rod one and the hanging rod two and their horizontal distances from the center of the gear disc decrease or increase, the horizontal distance from the spraying point of the spray gun to the center of the gear disc decreases or increases synchronously during the rotation of the spray gun along with the angle adjustment shaft, ensuring that the horizontal distance between the spraying point of the spray gun and the surface of the aluminum profile always remains constant, thereby greatly improving the quality of spraying and making the spraying effect present a uniform and beautiful appearance.

The highest point of the circumference where the chamfer is located on the side close to the conveying end of the conveying track 2 is lower than the tooth top height of the second rack 65.

[0041] Further, the rotation driving mechanism 5 includes a sleeve one 501 and a sleeve two 502 sleeved on the upper ends of the first hanging rod 31 and the second hanging rod 32 respectively. The sleeve one 501 and the sleeve two 502 are respectively rotatably connected to the gear disk 41 through a first rotating shaft 503 and a second rotating shaft 504. A first gear 505 and a second gear 506 are respectively provided on the first rotating shaft 503 and the second rotating shaft 504.

The third bevel gear 510 and the fourth bevel gear 511 are respectively connected to the first gear 505 and the second gear 506 through a connecting rod 512.

[0042] Further, the spray angle adjusting mechanism 8 includes an angle adjusting shaft 81 fixedly connected to the spray gun 7. The two ends of the angle adjusting shaft 81 are respectively rotatably connected to the spray gun support 9. The angle adjusting shaft 81 is connected to the lifting drive motor 61 through a synchronous drive mechanism 11.

[0043] Further, the synchronous drive mechanism 11 includes a first synchronous pulley 111 fixedly connected to the output shaft of the lifting drive motor 61 and a second synchronous pulley 112 fixedly connected to the angle adjusting shaft 81.

[0045] Further, a sealing cover 12 is provided at the top of the spraying chamber 1. The lifting drive mechanism 6 and the synchronous drive mechanism 11 are both located inside the sealing cover 12.

[0046] Further, the initial spray directions of the two spray guns 7 are respectively opposite to the top and bottom of the aluminum profile on the first hanging rod 31 and the second hanging rod 32 before the gear disk 41 rotates. The diameter of the circle where the moving trajectories of the spray points of the two spray guns 7 are located during the angle adjustment is equal to the diameter of the circle where the hanging points of the first hanging rod 31 and the second hanging rod 32 on the gear disk 41 are located during the rotation of the gear disk 41.

[0047] The working principle of the present invention is as follows: The aluminum profiles to be sprayed are respectively suspended on the first hanging rod 31 and the second hanging rod 32 in each aluminum profile hanging assembly 3. At this time, during the process that the aluminum profile hanging assembly 3 moves along the conveying track 2 to the designated position in the spraying chamber 1, the first hanging rod 31, the second hanging rod 32, and the aluminum profiles suspended on the first hanging rod 31 and the second hanging rod 32 maintain balance under their own action. At this time, the first hanging rod 31, the second hanging rod 32, and the two aluminum profiles are at the same height. At this time, the initial spraying directions of the two spray guns 7 are opposite to the top and bottom of the aluminum profiles on the first hanging rod 31 and the second hanging rod 32 respectively;

[0048] When the aluminum profile hanging assembly 3 moves along the conveying track 2 to the designated position in the spraying chamber 1, the two spray guns 7 start to spray the aluminum profiles. At the same time, the lifting drive mechanism 6 drives the gear disk 41 in the rotation adjustment mechanism 4 to rotate, and drives the aluminum profiles on the first hanging rod 31 and the second hanging rod 32 to rise and fall respectively, ensuring that whether it is the top, side, or bottom of the aluminum profiles suspended on the first hanging rod 31 and the second hanging rod 32 can be accurately included within the spraying range of the spray guns 7. While the gear disk 41 drives the first hanging rod 31 and the second hanging rod 32 to alternately rise and fall, it can also cooperate with the rotation drive mechanism 5 to drive the first hanging rod 31 and the second hanging rod 32 to rotate, so that the outer surfaces of the aluminum profiles suspended on the first hanging rod 31 and the second hanging rod 32 can be evenly sprayed, further ensuring the spraying quality. At the same time, during the operation of the spray guns 7, their spraying angles are adjusted in real time through the spraying angle adjustment mechanism 8, so as to ensure that the top, side, and bottom of the aluminum profiles can be evenly and completely covered with the spraying material, realizing a truly all-round and dead-angle-free spraying effect. Since the diameter of the circle where the movement trajectories of the spraying points of the two spray guns 7 are located during the angle adjustment process is equal to the diameter of the circle where the movement trajectories of the suspension points of the first hanging rod 31 and the second hanging rod 32 on the gear disk 41 are located when the gear disk 41 rotates, when the horizontal distance between the two aluminum profiles and the center of the gear disk 41 decreases or increases during the process of rising or falling with the first hanging rod 31 and the second hanging rod 32, the horizontal distance from the spraying point of the spray gun 7 to the center of the gear disk 41 synchronously decreases or increases during the process of rotating with the angle adjustment shaft 81, ensuring that the horizontal distance between the spraying point of the spray gun 7 and the surface of the aluminum profile always remains constant, thus greatly improving the spraying quality and making the spraying effect present a uniform and beautiful appearance. The whole process does not require manual intervention, which not only greatly reduces the operation difficulty, but also significantly reduces the material waste during the spraying process. At the same time, the device has a simple structure, low maintenance cost, and meets the environmental protection requirements.
