Description

Technical Field

[0001] This invention relates to the field of automatic spraying technology, specifically to an automatic spraying device. Background Technology

[0002] Automatic spraying equipment is a special tool that automatically covers metal and non-metal surfaces with protective or decorative layers, replacing manual labor with intelligent technology. It is generally used for reciprocating automatic spraying equipment in situations where the workpiece size is relatively fixed, the range of variation is small, large-scale production is carried out, and there is a workpiece conveying device.

[0003] In existing reciprocating automatic spraying equipment, the contouring program of the reciprocating sprayer can only adjust the extension and retraction, not the angle. Therefore, the reciprocating sprayer cannot achieve completely vertical spraying, resulting in a lower paint coverage on the side surface of the workpiece compared to other areas, leading to a thinner paint film on the side surface. While extending the contouring program or changing the gun shut-off time can allow the reciprocating machine to spray this area, it wastes paint and increases the cost of spraying. Furthermore, if side spraying is performed using fixed nozzles on the side, additional piping is required. When the equipment is not in use, the piping needs to be cleaned to prevent residual paint from solidifying and clogging the piping and nozzles. Cleaning and maintenance require disassembling the top and side nozzles separately, causing inconvenience in equipment cleaning.

[0004] Therefore, an automatic spraying device is proposed. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 6 The present invention provides a technical solution:

[0032] An automatic spraying device, such as Figure 1 As shown, it includes:

[0033] Base 1, with a transmission assembly 2 fixedly connected to its upper end;

[0034] Control component 3;

[0035] Exhaust pipe 5;

[0036] A spraying mechanism 4 is fixedly connected to the upper end of the base 1 near the control component 3. The spraying mechanism 4 can spray paint evenly onto the side surface of the workpiece during the spraying process.

[0037] In existing reciprocating automatic spraying equipment, the contouring program of the reciprocating sprayer can only adjust the extension and retraction, not the angle. Therefore, the reciprocating sprayer cannot achieve completely vertical spraying, resulting in a lower paint coverage on the side surface of the workpiece compared to other areas, leading to a thinner paint film on the side surface. While extending the contouring program or changing the cutoff time can allow the reciprocating machine to spray this area, it wastes paint and increases the cost of spraying. This invention, by setting up a spraying mechanism 4, first activates the transmission component 2, which transports the workpiece to the spraying mechanism 4 via a conveyor belt. The control component 3 sets the spraying conditions to match the spraying method with the workpiece, resulting in uniform paint film thickness on the upper and side surfaces of the workpiece. This improves the quality and efficiency of workpiece spraying, reduces paint waste, and saves production costs.

[0038] As one embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 3 As shown, the spraying mechanism 4 includes a first housing 41, a track 42, a moving component 43, a first spray gun 44, a second spray gun 45, a second spring 451, a first spring 46, a spraying pipe 47, a limiting plate 48, and rollers 49.

[0039] A first outer shell 41 is fixedly connected to the upper end of the base 1 near the control component 3. A track 42 is fixedly connected to one side of the inner surface of the first outer shell 41. A moving component 43 is slidably connected to the outer surface of the track 42. A first spray gun 44 is fixedly connected to the lower end of the moving component 43. A second spray gun 45 is symmetrically slidably connected to the lower outer surface of the first spray gun 44. A first spring 46 is fixedly connected to one end of the second spray gun 45. The first spray gun 44 is fixedly connected to the upper end of the first spring 46. A spraying pipe 47 is penetratingly connected to the outer surface of the second spray gun 45. Limiting plates 48 are symmetrically arranged at both ends of the outer surface of the track 42. A roller 49 is rotatably connected to the upper surface of the second spray gun 45 away from the first spray gun 44. A telescopic rod is inserted into the first spring 46. The two ends of the telescopic rod are fixedly connected to the corresponding first spray gun 44 and second spray gun 45, respectively.

[0040] To address the problems existing in the prior art, this invention, by setting up a spraying mechanism 4, firstly, activates the transmission component 2, which transports the workpiece to the spraying mechanism 4 via a conveyor belt. The control component 3 sets the spraying conditions to match the spraying method with the workpiece. Meanwhile, the moving component 43, propelled by a moving motor, moves on the track 42. The forward and reverse rotation of the built-in moving motor adjusts the direction of movement of the moving component 43, achieving reciprocating motion on the track 42. This, in turn, causes the first spray gun 44 to reciprocate on the track 42. Furthermore, the control component 3 adjusts the first spray gun 44 to spray paint onto the upper surface of the workpiece. When the moving component 43 moves to the position of the limiting plate 48, one end of the roller 49 contacts the limiting plate 48 and undergoes relative rolling motion. At this time, the second spray gun 45 at that end slides downward under the limitation of the limiting plate 48. At this point, the first spring 46... In the stretched state, when the nozzle of the second spray gun 45 is located at the center of the workpiece's side surface, the control component 3 controls the second spray gun 45 to spray paint via an electrical signal. Afterwards, the moving component 43 returns to its original position, and the second spray gun 45 at that end returns to its original height under the pull of the first spring 46. Similarly, the second spray gun 45 at the other end performs the same action. This method, by setting the second spray gun 45 so that when the first spray gun 44 completes its lateral displacement and reaches its end, the limiting plate 48 restricts the second spray gun 45 to spray the side surface of the workpiece. Rolling friction is used to position the second spray gun 45 on the side surface of the workpiece. During travel, the workpiece does not contact the second spray gun 45, achieving a uniform spraying effect on the workpiece's side surface and ensuring uniform paint film thickness on all surfaces of the workpiece. This avoids paint waste and saves production costs. Simultaneously, setting the second spray gun 45 on top of the first spray gun 44 reduces piping and makes cleaning easier compared to existing technologies.

[0041] As one embodiment of the present invention, such as Figure 4 , Figure 5 As shown, the inner surface of one end of the spraying pipe 47 is fixedly connected in a ring shape with a uniformly distributed first electric push rod 471, and a baffle 472 is fixedly connected to one end of the first electric push rod 471.

[0042] In practical work, since the height of most workpiece side surfaces is much smaller than the width of the workpiece top surface, the spray nozzles of general spray guns are circular, which is not conducive to spraying narrow surfaces and easily leads to paint waste. This invention sets up two baffles 472, which can activate the first electric push rod 471 to adjust the distance between the two baffles 472, thereby enlarging or shrinking the outlet of the spray pipe 47 and spraying paint sprays of different widths. By adjusting the baffles 472, the shape and size of the spray nozzle can be changed, making the sprayed paint flat and more effective for spraying narrow surfaces, thus avoiding paint waste.

[0043] As one embodiment of the present invention, such as Figure 4 As shown, uniformly distributed bouncing balls 473 are symmetrically fixedly connected to one side of the outer surface of the baffle 472. The bouncing balls 473 are spherical components made of rubber.

[0044] During the operation of the second spray gun 45, the paint is sprayed out from the spray pipe 47, impacting the baffle 472. Repeated impacts may cause the baffle 472 to loosen and shift, which is not conducive to the normal use of the baffle 472. The present invention provides a ball 473, which utilizes the elasticity of rubber. When the baffle 472 is subjected to impact, the ball 473 is squeezed. When the baffle 472 is not subjected to impact, the ball 473 returns to its original shape, thus limiting the position of the baffle 472 and preventing the baffle 472 from shifting and being difficult to recover.

[0045] As one embodiment of the present invention, such as Figure 2 As shown, a rotating component 481 is rotatably connected to the outer surface of the track 42 near the limiting plate 48 via a torsion spring 7. The limiting plate 48 is fixedly connected to the outer surface of the rotating component 481. A second electric push rod 40 is fixedly connected to the inner side surface of the first outer shell 41 near the limiting plate 48. The torsion spring 7 causes one end of the second electric push rod 40 to contact the limiting plate 48.

[0046] In practical work, the thickness of the workpiece varies, and the spraying effect is best only when the spraying pipe 47 is at the center of the side surface of the workpiece. This invention sets up a second electric push rod 40. When the second electric push rod 40 is activated, one end of the second electric push rod 40, which is fixedly connected to the limiting plate 48, pushes the limiting plate 48. The limiting plate 48 adjusts its angle with the rotating part 481 as the fulcrum. When the limiting plate 48 rotates downward, the downward height of the second spray gun 45 will increase, thereby realizing the adjustment of the downward height of the second spray gun 45 to adapt to workpieces of different thicknesses and ensure the spraying effect and quality.

[0047] As one embodiment of the present invention, such as Figure 2 , Figure 3 As shown, a second spring 451 is fixedly connected to the edge of the upper surface of the second spray gun 45, and one end of the second spring 451 is fixedly connected to the first spray gun 44.

[0048] During the descent of the second spray gun 45, the components are slidably connected, which may cause the second spray gun 45 to tilt or vibrate, which is not conducive to the normal operation of the spraying work. The present invention provides a second spring 451 to fix the end of the second spray gun 45 away from the first spray gun 44, thereby improving the stability of the second spray gun 45 during the movement and preventing the second spray gun 45 from tilting during the movement, thus improving work efficiency.

[0049] As one embodiment of the present invention, such as Figure 1 , Figure 6 As shown, a sewage discharge mechanism 6 is fixedly connected to the upper inner surface of the base 1 near the spraying mechanism 4. The sewage discharge mechanism 6 includes a second outer shell 61, a collection tray 62, a rotating motor 63, and a rotating plate 64. The second outer shell 61 is fixedly connected to the upper inner surface of the base 1 near the spraying mechanism 4. The collection tray 62 is fixedly connected to one end of the second outer shell 61 near the spraying mechanism 4. The rotating motor 63 is fixedly connected to the center of the lower inner surface of the collection tray 62. The rotating plate 64 is fixedly connected to one end of the output shaft of the rotating motor 63. The lower end of the rotating plate 64 is tightly connected to the lower inner surface of the collection tray 62.

[0050] In practical work, it is unavoidable that the paint does not completely adhere to the surface of the workpiece. Some paint settles after contact with air. If it falls directly onto the ground where the equipment is located, it is difficult to clean it later. This invention sets up a sewage discharge mechanism 6. During the spraying process, the paint that is not sprayed on the workpiece will fall from the spraying mechanism 4 into the sewage discharge mechanism 6. When the waste is in the collection tray 62, the output shaft of the rotating motor 63 rotates, causing the rotating plate 64 fixedly connected to it to rotate. The rotating plate 64 will scrape off the waste during the rotation. The scraped paint will fall into the second outer shell 61, thereby realizing the collection and reception of waste and avoiding the phenomenon of waste falling directly to the ground and causing pollution.

[0051] As one embodiment of the present invention, such as Figure 6 As shown, an installation block 65 is fixedly connected to the inner side surface of the second outer shell 61 near the collection tray 62. A third spring 66 is fixedly connected to one end of the installation block 65, and a cleaning block 67 is fixedly connected to one end of the third spring 66. One end of the cleaning block 67 is tightly connected to the rotating plate 64.

[0052] During the scraping process of the rotary plate 64 in the collection tray 62, the waste may adhere to the outer surface of the rotary plate 64. The accumulated waste will make it difficult for the rotary plate 64 to move, thereby reducing the cleaning efficiency of the rotary plate 64 and affecting the normal operation of the sewage discharge mechanism 6. The present invention sets up a cleaning block 67. When the rotary plate 64 rotates, it will slide and rub against the cleaning block 67. During the friction process, the cleaning block 67 will clean the waste adhering to the surface of the rotary plate 64. At the same time, the rotary plate 64 will push the cleaning block 67 to move towards the mounting block 65. During the movement, the third spring 66 is compressed, so that the cleaning block 67 can thoroughly clean the convex surfaces of the two rotary plates 64, ensuring the cleaning effect of the rotary plate 64 on the waste in the collection tray 62.

[0053] As one embodiment of the present invention, such as Figure 6 As shown, a water spray pipe 641 is connected through the center of the side surface of the rotary plate 64, and a water collection tank 68 is fixedly connected to one end of the second outer shell 61.

[0054] When waste falls into the collection tray 62, the rotating plate 64 may not clean the waste in time. As the moisture in the waste evaporates, the waste sticks to the surface of the collection tray 62 and is difficult to clean. After a long period of operation, the gap between the rotating plate 64 and the collection tray 62 may increase, causing component failure and hindering the normal cleaning work. This invention solves this problem by setting up a water spray pipe 641, connecting an external water source, and continuously spraying water into the collection tray 62 during the rotation of the rotating plate 64. This allows the waste to be cleaned by the rotating plate 64 along with the water flow, preventing the moisture in the waste from evaporating and ensuring that the rotating plate 64 can clean the waste.

[0055] As one embodiment of the present invention, such as Figure 6 As shown, a filter tank 681 is fixedly connected inside the water collection tank 68 near the collection plate 62. The filter tank 681 is connected to the collection plate 62, and a filter bag 682 is fixedly connected to the lower end of the filter tank 681.

[0056] When waste accumulates excessively and comes into contact with water, it will form viscous clumps, which will cause blockage of the drainage pipes and hinder the normal operation of the sewage discharge mechanism 6. This invention, by setting up components such as a filter tank 681, allows the mixture of waste and water to flow from the collection tray 62 to the water collection tank 68. At this time, the mixture first passes through the filter tank 681, and the mixture is filtered by the filter bag 682. The filtered liquid is discharged through the drainage pipe, preventing the clumps of paint from being discharged further and avoiding blockage of the pipes.

[0057] Usage: In use, the transmission assembly 2 is first activated, which transports the workpiece to the spraying mechanism 4 via a conveyor belt. The control assembly 3 sets the spraying conditions to match the workpiece. The moving assembly 43 uses a moving motor to make the first spray gun 44 reciprocate on the track 42. The control assembly 3 then adjusts the first spray gun 44 to spray paint onto the upper surface of the workpiece. When the moving assembly 43 moves to the position of the limiting plate 48, one end of the roller 49 contacts the limiting plate 48 and undergoes relative rolling motion. At this time, the second spray gun 45 at that end will be limited by the limiting plate 48. The spray pipe 47 slides downwards, at which point the first spring 46 is stretched. When the spray pipe 47 is at the center of the workpiece's side surface, the control component 3 controls the second spray gun 45 to spray paint via an electrical signal. Afterwards, the moving component 43 returns to its original position, and the second spray gun 45 at this end will return to its original height under the pull of the first spring 46. Similarly, the second spray gun 45 at the other end performs the same action. For workpieces of different specifications and with different spraying requirements, the first electric push rod 471 can be activated to adjust the distance between the two baffles 472, thereby enlarging or shrinking the outlet size of the spray pipe 47 and spraying paint sprays of different widths. Simultaneously, the second electric push rod 40 can be activated, causing the end of the second electric push rod 40 that is tightly connected to the limiting plate 48 to push the limiting plate 48. This allows the limiting plate 48 to adjust its angle using the rotating part 481 as a fulcrum, thereby adjusting the downward height of the second spray gun 45 to accommodate workpieces of different thicknesses. During the spraying process, any paint not sprayed onto the workpiece will fall from the spraying mechanism 4 into the waste discharge mechanism 6. When the waste material is in the collection tray 62, the output shaft of the rotating motor 63 rotates, causing the rotating plate 64 fixedly connected to it to rotate. The rotating plate 64 will scrape off the waste material during the rotation process. At the same time, the water source connected to the water spray pipe 641 releases water, spraying clean water onto the collection tray. Inside the collecting tray 62, the auxiliary rotating plate 64 removes waste. When the rotating plate 64 rotates, it slides and rubs against the cleaning block 67. During the friction process, the cleaning block 67 cleans the waste adhering to the surface of the rotating plate 64. At the same time, the rotating plate 64 pushes the cleaning block 67 towards the mounting block 65. During the movement, the third spring 66 is compressed, allowing the cleaning block 67 to thoroughly clean both rotating plates 64. The mixture of waste and water flows from the collecting tray 62 to the water collection tank 68. At this time, the mixture first passes through the filter tank 681, and the filter bag 682 filters the mixture to prevent the clumps of paint from being discharged further and to avoid clogging the pipes.
