[0002] After the stainless steel wire is produced and formed and processed through multiple processes, a protective film needs to be coated on its surface to improve the service life of the stainless steel wire and reduce the corrosion rate of the surface of the stainless steel wire by the external harsh environment. The existing stainless steel wire surface is often sprayed by electrostatic spraying. The stainless steel wire can be output continuously, and the spraying efficiency is high. Since the spraying gun is located on one side of the stainless steel wire and the stainless steel wire is in an open environment during spraying, the waste of paint is large, the working environment is polluted, and the spraying on the side far from the spraying gun is uneven.

The closed spray barrel structure avoids the escape of paint and saves materials. However, when it is used, spraying the stainless steel welding wire with a plurality of atomizing nozzles will cause a part of the paint to converge into droplets and then drip into the spray barrel, resulting in waste of some paint.

Detailed implementation manners

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and implementation manners.

[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 wherein Figure 1 is a schematic structural diagram of a preferred embodiment of the stainless steel wire electrostatic spraying device provided by the present utility model; Figure 2 is Figure 1 a schematic structural diagram of the collection assembly shown; Figure 3 is Figure 1 a schematic diagram of the internal structure of the spraying box shown; Figure 4 is Figure 1 a schematic structural connection diagram of the spraying cylinder and the first annular pipe shown; Figure 5 is Figure 1 a schematic structural diagram of the motor and the first conveying roller shown. A stainless steel wire electrostatic spraying device includes a spraying box 1, a paint box 2 is fixedly connected to the front surface of the spraying box 1, a conveying pump 3 is fixedly connected to the top of the paint box 2, and a connecting pipe 4 is communicated with the liquid outlet of the conveying pump 3;

[0026] A collection assembly 5 is arranged on the front surface of the spraying box 1. The collection assembly 5 includes a collection box 51, a temperature sensor 52, a stirring mechanism 53 and an extraction pump 54. The collection box 51 is fixedly connected to the front surface of the spraying box 1, the temperature sensor 52 is arranged at the bottom of the inner cavity of the collection box 51, the stirring mechanism 53 is arranged at the bottom of the inner cavity of the collection box 51, and the extraction pump 54 is arranged on one side of the collection box 51.

[0027] In the specific implementation process, as shown in Figure 1 、 Figure 2 and Figure 3 a collection pipe 6 is communicated with the inside of the collection box 51, and an extraction pipe 7 is communicated with the liquid inlet of the extraction pump 54.

[0028] A heating plate 8 is arranged on the inner wall of the collection box 51, and a PLC controller 9 is arranged on the front surface of the collection box 51.

[0029] One side of the inner wall of the spraying box 1 is fixedly connected with a spraying cylinder 10, inclined plates 11 are fixedly connected to both sides of the inner wall of the spraying box 1, and a collecting groove 12 is formed inside the spraying box 1.

[0030] It should be noted that: in the process of spraying the welding wire, part of the coating gathers on the surface of the welding wire to form coating droplets. The coating droplets can pass through the filter 14 to separate from the inside of the spray barrel 10, and then the coating drops on the top of the inclined plate 11. Under the action of the inclined plate 11, the coating droplets reach the collecting tank 12, and then the staff starts the extraction pump 54. Under the action of the extraction pump 54 and the extraction pipe 7, the droplets collected in the collecting tank 12 can be extracted and then transported to the inside of the collecting box 51. At the same time, through the PLC controller 9, the stirring mechanism 53 starts to operate, and the heating plate 8 starts to move, so that the coating in the collecting box 51 can be stirred and heated to prevent the coating from condensing during the collection process. After the welding wire is sprayed, the staff can process the collected coating through the collection pipe 6 for secondary use to reduce coating waste.

[0031] refer to Figure 3 and Figure 4 As shown, a first annular tube 13 is disposed on the outside of the spray barrel 10 , a filter screen 14 is disposed inside the spray barrel 10 , and a sealing ring 15 is disposed inside the spray barrel 10 .

[0032] One side of the first annular tube 13 is connected to a side tube 16 , an end of the side tube 16 away from the first annular tube 13 is connected to a second annular tube 17 , and an end of the connecting tube 4 away from the delivery pump 3 is connected to the top of the second annular tube 17 .

[0033] It should be noted that: when the welding wire is being sprayed, the welding wire passes through the inside of the spray barrel 10, and then the delivery pump 3 starts working. Under the action of the delivery pump 3, the paint inside the paint box 2 is extracted, and then transported through the connecting pipe 4. The paint enters the inside of the first annular tube 13 and the second annular tube 17, and then the welding wire is sprayed through the spray head.

[0034] refer to Figure 5 As shown, a motor 18 is fixedly connected to one side of the spray box 1 , a first conveying roller 19 is fixedly connected to the output end of the motor 18 , and a first connecting wheel 20 is fixedly connected to the outer side of the first conveying roller 19 .

[0035] The outer side of the first connecting wheel 20 is connected to the second connecting wheel 21 through a connecting belt transmission, the inner ring of the second connecting wheel 21 is fixedly connected to the second conveying roller 22, and the outer sides of the first conveying roller 19 and the second conveying roller 22 are both provided with a first friction sleeve 23.

[0036] A third conveying roller 24 is rotatably connected to one side of the spray box 1 , and a second friction sleeve 25 is disposed on the outer side of the third conveying roller 24 .

[0037] The top of the spray box 1 is connected to a purification box 26 , and an adsorption plate 27 is provided inside the purification box 26 .

[0038] It should be noted that when spray coating operation needs to be carried out on the wire feeding, the motor 18 is first started. Under the action of the motor 18, the first conveying roller 19 and the first connecting wheel 20 can be driven to rotate. Furthermore, the second connecting wheel 21 and the second conveying roller 22 can be rotated, so that the wire can be conveyed under the action of the first friction sleeve 23 and the second friction sleeve 25. At the same time, the gas generated during the spraying process can be processed by the adsorption plate 27 inside the purification box 26 to prevent the gas from affecting the surrounding working environment.

[0039] The working principle of a static spraying device for stainless steel welding wires provided by the present utility model is as follows:

[0040] When the staff performs spraying operation on the stainless steel welding wire through this device, part of the coating accumulates on the surface of the wire to form coating droplets. The coating liquid separates from the inside of the spraying cylinder 10 through the filter screen 14. Under the action of the inclined plate 11, the coating can accumulate inside the collecting groove 12. Under the action of the extraction pump 54, the coating collected inside the collecting groove 12 can be extracted and then conveyed to the inside of the collecting box 51. Then, the staff makes the stirring mechanism 53 and the heating plate 8 start working through the PLC controller 9, and then the coating inside the collecting box 51 can be stirred and heated to prevent the coating inside the collecting box 51 from coagulating. Then, the staff can uniformly process the collected coating through the collecting pipe 6, so that the collected coating can be reused, reducing coating waste.
