Description

Technical Field

[0001] This utility model relates to the field of sheet metal spraying technology, and in particular to a sheet metal spraying device. Background Technology

[0002] Sheet metal is a processing technology. There is no complete definition of sheet metal to date. According to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold processing technology for thin metal sheets (usually less than 6mm), including shearing, punching, cutting, compounding, bending, riveting, splicing, and forming (such as car body). Its significant feature is that the thickness of the same part is consistent.

[0003] A patent with publication number CN110496736A discloses a sheet metal parts spraying device, including a supporting base plate, a transmission screw, and an auxiliary connecting rod, all rotatably connected to the top of which are damping couplings. Each damping coupling has a fixedly connected adsorption magnet on its top, and each adsorption magnet has an anti-slip surface on its top. An electric telescopic rod is fixedly connected to the bottom of an adjusting slider, outside the adjusting groove. A spraying carrier plate is fixedly connected to the output end of the electric telescopic rod away from the adjusting slider. A level detection controller is fixedly connected to the left side of the bottom of the spraying carrier plate, a paint storage tank is fixedly connected to the right side of the top of the spraying carrier plate, a high-pressure liquid pump is fixedly connected to the top of the spraying carrier plate, and an atomizing nozzle is fixedly connected to the middle position of the bottom of the spraying carrier plate. This invention relates to the field of sheet metal processing technology. This sheet metal parts spraying device achieves the goals of ensuring uniform sheet metal spraying, reducing labor costs, and improving the quality of sheet metal parts spraying.

[0004] When painting existing sheet metal, it needs to be fixed in a specific position. To prevent paint leakage, the sheet metal needs to be placed in a sealed environment. However, the sealed environment prevents the sheet metal from being flipped, resulting in only one side being painted. The painting box needs to be opened later to flip it over and fix it before a second painting. However, the sealed box is filled with a large amount of painting gas, and the door can only be opened after the painting gas has settled naturally. However, the natural settling speed of the painting gas is relatively slow, which wastes a lot of time in the entire painting process and seriously affects the painting efficiency. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that in the prior art, the sealed box is filled with a large amount of spraying gas, and the box door can only be opened after the spraying gas inside has settled naturally. However, the natural settling speed of the spraying gas is relatively slow, which wastes a lot of time in the entire spraying process and seriously affects the spraying efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a sheet metal spraying device, including a sheet metal spraying box and a detachable closed cover installed on the outer surface of the top of the sheet metal spraying box, a sealing door movably fitted onto the inner wall of the sheet metal spraying box, a water tank fixedly installed on the bottom surface of the sheet metal spraying box at the middle position, the interior of the water tank being filled with sodium bicarbonate solution, a shielding mesh plate fixedly connected to the inner wall of the water tank, and multiple return air pipes fixedly installed on the outer surface of the water tank, the other ends of the multiple return air pipes extending to the inner bottom wall of the sheet metal spraying box.

[0007] In one embodiment of the present invention, overlapping strips are fixedly connected to the inner walls on both sides of the sheet metal spray painting box, and a blocking block is provided on the top surface of the overlapping strip and at one side edge position. A limiting groove is formed on the inner walls on both sides of the sheet metal spray painting box and at the top edge position of the overlapping strip.

[0008] In one embodiment of the present invention, an overlapping plate is fixedly installed on one side surface of the sealing door, the bottom surface of the overlapping plate is movably overlapping the top surface of the overlapping strip, and limit rods are fixedly connected to both sides of the overlapping plate.

[0009] In one embodiment of this utility model, the outer surface of the limiting rod is movably sleeved on the inner wall of the limiting groove, and a slot is provided on the top surface of the overlapping plate at the middle position. Two sets of bearings are symmetrically fixedly installed on the inner walls of both sides of the overlapping plate.

[0010] In one embodiment of this utility model, a motor is fixedly installed on the outer surface of the sealing door, and the output end surface of the motor is movably connected to the inner wall surface of a set of bearings.

[0011] In one embodiment of the present invention, a flip plate disposed inside the slot is fixedly connected to the output end of the motor, and a support rod movably overlapping the inner wall of another set of bearings is fixedly connected to the other side surface of the flip plate.

[0012] In one embodiment of the present invention, a lower pressure strip is oscillatingly connected to the top surface of the flip plate and located at one side edge. A pin hole is provided on one end of the lower pressure strip. A docking groove is provided on the top surface of the flip plate and located at the other side edge. A pin rod provided on the inner wall of the pin hole is movably sleeved on the inner wall of the docking groove. A trapezoidal soft block is provided on the top surface of the flip plate.

[0013] In one embodiment of the present invention, a paint tank is fixedly installed on the top surface of the closed cover, and a paint spray head is fixedly installed on the bottom surface of the closed cover and at the two side edges. A paint spray pipe passing through the outer surface of the closed cover and disposed on the input end of the paint spray head is fixedly connected to the output end of the paint tank.

[0014] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0015] The sheet metal spraying device of this utility model, after spraying the coating liquid, uses return air pipes of different heights to absorb the gas inside the sheet metal spraying box, and guides the absorbed coating liquid into the interior of the water tank. As the gas and coating liquid spread and soak inside the water tank, the coating liquid is left in the sodium bicarbonate inside the water tank. As the bubbles rise, the filter screen on the inner surface of the water tank breaks the bubbles inside the sodium bicarbonate into smaller bubbles, thereby increasing the contact range and area between the bubbles and the sodium bicarbonate. The acidic solution inside the sodium bicarbonate allows the sodium bicarbonate to neutralize the coating liquid, thereby generating carbon dioxide and water, which greatly reduces the accumulation of harmful gases.

[0016] The sheet metal spraying device of this utility model utilizes limiting rods on both sides of the flip plate to slide on the inner wall of the limiting groove, thereby sealing the entrance of the sheet metal spraying box. At this time, the paint box is used to fill the spray head with coating gas. By using the tilt angle of the spray head, the coating is sprayed from top to bottom over a wide area, which allows the coating to be evenly covered on the surface of the sheet metal. At the same time, the flip plate is rotated by a motor. During the rotation, the flip plate can flip the sheet metal and apply the coating. Moreover, as the sheet metal is continuously flipped, the coating can be evenly spread on the four edges of the sheet metal.

[0017] The sheet metal spraying device of this utility model overlaps the sheet metal on the top surface of the flip plate, and the swinging pressure strip overlaps the surface of the sheet metal. The pressure strip is fixed to the outer surface of the flip plate by a pin rod passing through the pin hole. As the pressure strip is squeezed, the sheet metal is firmly positioned on the surface of the flip plate. The squeezing of the sheet metal can increase the friction and anti-slip force between the trapezoidal soft block and the sheet metal, so that the sheet metal can always be positioned on the outer surface of the flip plate without slight movement.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1 - Figure 6As shown, this utility model discloses a sheet metal spraying device, including a sheet metal spraying box 11 and a detachable closed cover 12 installed on the outer surface of the top of the sheet metal spraying box 11, a sealing door 13 movably sleeved on the inner wall of the sheet metal spraying box 11, a water tank 115 fixedly installed on the bottom surface of the sheet metal spraying box 11 at the middle position, the water tank 115 being filled with sodium bicarbonate solution, a shielding mesh 116 fixedly connected to the inner wall of the water tank 115, and multiple return air pipes 114 fixedly installed on the outer surface of the water tank 115, with the other end of the multiple return air pipes 114 extending to the bottom of the sheet metal spraying box 11. On the inner wall of the sheet metal spray paint box 11, overlapping strips 111 are fixedly connected to the inner walls on both sides. A blocking block 112 is provided on the top surface of the overlapping strip 111 and at one side edge. A limiting groove 113 is provided on the inner walls on both sides of the sheet metal spray paint box 11 and at the top edge of the overlapping strip 111. A paint box 121 is fixedly installed on the top surface of the closed cover 12. A spray nozzle 123 is fixedly installed on the bottom surface of the closed cover 12 and at both side edges. A spray pipe 122 is fixedly connected to the output end of the paint box 121, passing through the outer surface of the closed cover 12 and provided on the input end of the spray nozzle 123.

[0028] To remove chemicals from the sheet metal surface and paint vapors diffused inside the sheet metal spray booth 11, after spraying the paint, return air pipes 114 at different heights absorb the gases inside the sheet metal spray booth 11. The absorbed paint is then guided into the water tank 115. As the gases and paint diffuse and soak inside the water tank 115, the paint is left in the sodium bicarbonate inside the water tank 115. As the bubbles rise, the filter screen on the inner surface of the water tank 115 breaks the bubbles inside the sodium bicarbonate into smaller bubbles, thereby increasing the contact area between the bubbles and the sodium bicarbonate. The acidic solution inside the sodium bicarbonate neutralizes the paint, producing carbon dioxide and water. This greatly reduces the accumulation of harmful gases and decreases the density of paint vapors inside the sheet metal spray booth 11, preventing the paint vapors from spreading out when workers open the sheet metal spray booth 11 and thus avoiding potential health hazards to nearby employees.

[0029] Reference Figure 4 As shown, in one embodiment of the present invention, a lower pressure bar a2 is oscillatingly connected to the top surface of the flip plate 136 and located at one side edge. A pin hole a3 is provided on one end of the lower pressure bar a2. A docking groove is provided on the top surface of the flip plate 136 and located at the other side edge. A pin rod a4 provided on the inner wall of the pin hole a3 is movably sleeved on the inner wall of the docking groove. A trapezoidal soft block a1 is provided on the top surface of the flip plate 136.

[0030] The sheet metal is overlapped on the top surface of the flip plate 136. The swinging pressure bar a2 overlaps on the surface of the sheet metal, and the pressure bar a2 is fixed to the outer surface of the flip plate 136 by the pin rod a4 passing through the pin hole a3. As the pressure bar a2 is squeezed, the sheet metal is firmly positioned on the surface of the flip plate 136. The squeezing of the sheet metal can increase the friction and anti-slip force between the trapezoidal soft block a1 and the sheet metal, so that the sheet metal can always be positioned on the outer surface of the flip plate 136 without producing a slight movement effect.

[0031] Reference Figure 1 - Figure 6 As shown, in one embodiment of this utility model, an overlapping plate 132 is fixedly installed on one side surface of the sealing door 13. The bottom surface of the overlapping plate 132 is movably overlapped with the top surface of the overlapping strip 111. Limiting rods 133 are fixedly connected to both sides of the overlapping plate 132. The outer surface of the limiting rods 133 is movably sleeved on the inner wall of the limiting groove 113. A slot 134 is provided on the top surface of the overlapping plate 132 at the middle position. Two sets of bearings 135 are symmetrically fixedly installed on the inner walls of both sides of the overlapping plate 132. A motor 131 is fixedly installed on the outer surface of the sealing door 13. The output end surface of the motor 131 is movably overlapped with the inner wall of one set of bearings 135. A flipping plate 136 disposed inside the slot 134 is fixedly connected to the output end of the motor 131. A support rod is fixedly connected to the other side surface of the flipping plate 136 and movably overlapped with the inner wall of another set of bearings 135.

[0032] The limiting rods 133 on both sides of the flip plate 136 slide on the inner wall of the limiting groove 113, so that the sealing door 13 is closed at the entrance of the sheet metal spraying box 11. At this time, the paint box 121 fills the inside of the spray nozzle 123 with coating gas. Using the tilt angle of the spray nozzle 123, the coating liquid is sprayed from top to bottom over a wide area. The wide spray can make the coating liquid evenly cover the surface of the sheet metal. At this time, the motor 131 rotates the flip plate 136. During the rotation, the flip plate 136 can flip the sheet metal and apply the coating liquid. Moreover, as the sheet metal is continuously flipped, the coating liquid can be evenly spread on the four edges of the sheet metal.

[0033] Working principle: The sheet metal is overlapped on the top surface of the flip plate 136. The swinging pressure bar a2 overlaps on the surface of the sheet metal, and the pressure bar a2 is fixed to the outer surface of the flip plate 136 by the pin rod a4 passing through the pin hole a3. As the pressure bar a2 is squeezed, the sheet metal is firmly positioned on the surface of the flip plate 136. The squeezing of the sheet metal can increase the friction and anti-slip force between the trapezoidal soft block a1 and the sheet metal, so that the sheet metal can always be positioned on the outer surface of the flip plate 136 without producing a slight movement effect.

[0034] The limiting rods 133 on both sides of the flip plate 136 slide on the inner wall of the limiting groove 113, so that the sealing door 13 is closed at the entrance of the sheet metal spraying box 11. At this time, the paint box 121 fills the inside of the spray nozzle 123 with coating gas. The tilt angle of the spray nozzle 123 makes the coating sprayed from top to bottom over a wide area. The wide spray can make the coating evenly cover the surface of the sheet metal. At this time, the motor 131 rotates the flip plate 136. During the rotation, the flip plate 136 can flip the sheet metal and apply the coating. Moreover, as the sheet metal is continuously flipped, the coating can be evenly spread on the four edges of the sheet metal.

[0035] To remove chemicals from the sheet metal surface and paint vapors diffused inside the sheet metal spray booth 11, after spraying the paint, return air pipes 114 at different heights absorb the gases inside the sheet metal spray booth 11. The absorbed paint is then guided into the water tank 115. As the gases and paint diffuse and soak inside the water tank 115, the paint is left in the sodium bicarbonate inside the water tank 115. As the bubbles rise, the filter screen on the inner surface of the water tank 115 breaks the bubbles inside the sodium bicarbonate into smaller bubbles, thereby increasing the contact area between the bubbles and the sodium bicarbonate. The acidic solution inside the sodium bicarbonate neutralizes the paint, producing carbon dioxide and water, greatly reducing the accumulation of harmful gases.

[0036] Obviously, the above embodiments are merely illustrative examples for clarity and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
