Description

Technical Field

[0001] This utility model belongs to the field of cold-formed steel painting technology, and specifically relates to a spraying device for cold-formed steel processing. Background Technology

[0002] Spraying equipment for cold-formed steel is mainly used to spray anti-corrosion coatings onto cold-formed steel to improve its corrosion resistance and service life. This equipment typically includes the following parts: a spray box: used to contain the cold-formed steel and the spraying process, preventing the anti-corrosion coating from spreading into the workshop environment; and atomizing nozzles: multiple nozzles atomize the anti-corrosion coating and spray it out, evenly covering the surface of the cold-formed steel.

[0003] Existing spraying equipment for cold-formed steel processing involves personnel placing the cold-formed steel into a spraying box, followed by spraying anti-corrosion coating liquid through multiple atomizing nozzles. During the spraying process, the atomized anti-corrosion coating liquid diffuses inside the spraying box. Although this can prevent it from spreading throughout the workshop, when personnel open the spraying box to replace the coated cold-formed steel, they will inevitably inhale the anti-corrosion coating liquid, even while wearing masks. The anti-corrosion coating liquid contains harmful chemicals, and long-term inhalation can harm the respiratory system and health of operators, posing a potential threat to human health. Furthermore, although the spraying box can reduce the diffusion of anti-corrosion coating liquid in the workshop, some coating liquid will still escape when the spraying box is opened, affecting the air quality in the workshop. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a spraying device for cold-formed steel processing. The device is equipped with a function to collect and treat the anti-corrosion coating liquid that diffuses inside the spraying box, ensuring that personnel will not inhale the anti-corrosion coating liquid when opening the spraying box to replace cold-formed steel, significantly reducing health risks, reducing the release of harmful substances in the workshop, and improving the overall quality of the working environment.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a spraying device for cold-formed steel processing, including a spraying box, a cavity plate inside the spraying box, multiple spraying holes at the lower end of the cavity plate each equipped with an atomizing spray head, and liquid inlet holes on the left side of the cavity plate each equipped with a liquid inlet pipe. A box door panel is hinged to the front side of the spraying box. A coating liquid-containing gas collection and treatment mechanism is provided at the upper end of the spraying box. A rotating clamping mechanism is provided inside the spraying box. The coating liquid-containing gas collection and treatment mechanism includes a treatment box located at the upper end of the spraying box, which is connected to the interior of the spraying box. A filter plate is slidably arranged inside the treatment box. A handle is provided on the front side of the filter plate. A fan is provided on the top wall of the treatment box. Multiple slots are opened at the upper end of the interior of the treatment box. Multiple air inlet slots are opened on the right side of the spraying box. An electric push rod is provided on the right side of the spraying box. A sealing plate that cooperates with the air inlet slots is provided on the telescopic end of the electric push rod.

[0006] As a further improvement of this utility model, a liquid outlet pipe is provided at the lower end of the spray box, which is connected to the interior of the spray box, and a solenoid valve is connected in series in the middle of the liquid outlet pipe.

[0007] As a further improvement of this utility model, the rotating clamping mechanism includes two electric push rods that are rotatably arranged on the left and right sides inside the spray box via a rotating column. Each of the telescopic ends of the electric push rods is provided with a clamping plate, and the left and right positions of the multiple clamping plates are corresponding. An electric drive unit for driving the rotating column to rotate is provided on the left side of the spray box. The electric drive unit includes a motor located on the left side of the spray box, and the output shaft of the motor is connected to the left end of the leftmost rotating column through a coupling.

[0008] As a further improvement of this utility model, a control panel is provided on the front side of the spray box, and the fan, electric push rod one, electric push rod two, motor and solenoid valve are all electrically connected to the control panel.

[0009] As a further improvement of this utility model, the lower end of the spray box is provided with two support mounting brackets corresponding to the left and right positions, and the spray box and the support mounting brackets are fixed by welding.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Firstly, by opening the cabinet door, the cold-formed steel to be coated is placed between two clamping plates. Then, the electric push rod is activated via the control panel, causing the extension end to move the clamping plates closer together to clamp and fix the cold-formed steel. Next, the cabinet door is closed, and the liquid inlet pipe is connected to the external liquid pump, allowing the anti-corrosion liquid to enter the cavity plate and be sprayed onto the cold-formed steel through the atomizing spray head, thus achieving coating of the cold-formed steel. Alternatively, the motor can be activated via the control panel, and the output shaft drives the cold-formed steel between the two clamping plates on the rotating column to rotate, thereby quickly achieving rapid and comprehensive coating of the cold-formed steel.

[0012] Secondly, by controlling the liquid pump to shut off, and then controlling the electric push rod one to operate via the control panel, the telescopic end moves the sealing plate upward to expose the air inlet. The fan is then turned on via the control panel, and the impeller rotates, drawing the coating-containing gas generated during spraying into the treatment chamber. The gas is then adsorbed and filtered by the filter plate, and the filtered air is discharged through the inlet. External air enters the spraying chamber through the air inlet, thus collecting and filtering the coating-containing gas inside the spraying chamber. Personnel can then open the chamber door and use the electric push rod two via the control panel to remove the cold-formed steel. The system also collects and treats the anti-corrosion coating liquid that permeates the spraying chamber, ensuring that personnel do not inhale the anti-corrosion coating liquid when opening the spraying chamber to replace the cold-formed steel, significantly reducing health risks and minimizing the release of harmful substances into the workshop, thus improving the overall quality of the working environment.

[0013] Third, the anti-corrosion coating that is not sprayed onto the cold-formed steel will be stored at the bottom of the spray box. Personnel can open the solenoid valve through the control panel to discharge the anti-corrosion coating inside the spray box for reuse, thereby improving the utilization of the anti-corrosion coating.

[0014] Fourth, the support frame can provide stable support for the spraying device, ensuring more stable operation of the spraying device and improving the spraying quality of cold-formed steel. Attached Figure Description

A coating liquid-containing gas collection and treatment mechanism is provided at the upper end of the spraying box 101. The interior of the spray box 101 is equipped with a rotating clamping mechanism, which includes electric push rods 301 that are rotatably mounted on the left and right sides inside the spray box 101 via a rotating column. Each of the electric push rods has a clamping plate 302 on its telescopic end. An electric drive unit for driving the rotating column is located on the left side of the spray box 101. The electric drive unit includes a motor 303 located on the left side of the spray box 101. The output shaft of the motor 303 is connected to the left end of the leftmost rotating column via a coupling.

[0023] like Figure 1 , 4As shown, the coating liquid gas collection and treatment mechanism includes a treatment box 201 located at the upper end of the spray box 101. The treatment box 201 is connected to the interior of the spray box 101. A filter plate 202 is slidably arranged inside the treatment box 201. A handle is provided on the front side of the filter plate 202. A fan 203 is provided on the top wall of the treatment box 201. The filter plate 202 is located below the fan 203. Multiple slots are opened at the upper end of the interior of the treatment box 201. Multiple air inlets 206 are opened on the right side of the spray box 101. An electric push rod 204 is provided on the right side of the spray box 101. A sealing plate 205 is provided on the telescopic end of the electric push rod to cooperate with the air inlets 206.

[0024] like Figure 2 , 3 As shown, a liquid outlet pipe 108 is provided at the lower end of the spraying box 101. The liquid outlet pipe 108 is connected to the interior of the spraying box 101, and a solenoid valve 109 is connected in series in the middle of the liquid outlet pipe 108.

[0025] like Figure 1 As shown, a control panel 103 is provided on the front side of the spray box 101. The fan 203, electric push rod 1 204, electric push rod 2 301, motor 303 and solenoid valve 109 are all electrically connected to the control panel 103.

[0026] By opening the box door 102, the cold-formed steel to be sprayed is placed between the two clamping plates 302. Then, the electric push rod 301 is opened via the control panel 103, and the telescopic end drives the clamping plates 302 to move closer together to clamp and fix the cold-formed steel. Next, the box door 102 is closed, and then the liquid inlet pipe 107 is connected to the external liquid pump, so that the anti-corrosion liquid enters the cavity plate 105 and is sprayed onto the cold-formed steel through the atomizing spray head 106 to achieve the spraying of the cold-formed steel.

The telescopic end drives the sealing plate 205 to move upward, exposing the air inlet 206. Then, the fan 203 is opened via the control panel 103. The impeller rotates, causing the coating liquid-containing gas generated inside the coating box 101 to be drawn into the processing box 201. The coating liquid-containing gas is adsorbed and filtered by the filter plate 202. The filtered air is discharged through the slot, while the outside air enters the interior of the coating box 101 through the air inlet 206. This allows for the collection and filtration of the coating liquid-containing gas inside the coating box 101. Then, personnel can open the box door 102 and use the electric push rod 301 controlled by the control panel 103 to remove the cold-formed steel. The filter plate 202 sliding inside the processing box 201 can be removed and replaced by the handle.

[0028] The anti-corrosion coating liquid that is not sprayed onto the cold-formed steel will be stored at the bottom of the spray box 101. Personnel can open the solenoid valve 109 through the control panel 103 to discharge the anti-corrosion coating liquid inside the spray box 101 for reuse.
