The spray equipment that a kind of can seam is used
Technical field
The present invention relates to a kind of spray equipment, especially the spray equipment of using for a kind of can seam.
Background technology
In can manufacturing technology, need butt welded seam to carry out a kind of coating of coating after tank body welded and make it to be difficult for getting rusty.As shown in Figure 2, prior art generally is to adopt liquid coating also to brush with the thing of brush and so on.During brushing,, thereby make that the coating front and back amount of butt welded seam is inconsistent, the very easy quality problems that cause owing to liquid coating is to be delivered on the brush by the mode of dripping or the circle wheel rotates.And brush and be not easy to Artificial Control.
Summary of the invention
At the problems referred to above, the invention provides the spray equipment that a kind of can seam is used, coating can be brushed on the weld seam of tank body uniformly.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the spray equipment that a kind of can seam is used, it comprises that one is used to carry the conveying device of tank body, conveying track along conveying device is provided with the brush that is used to spray the shower nozzle of coating and is positioned at the shower nozzle downstream, this spray equipment also comprises the control device that is used to respond to the induction installation of weld seam and is used to control shower nozzle, and described induction installation is electrically connected mutually with described control device.
Preferably, shower nozzle shown in is an atomizer.
The present invention adopts above structure, has improved the quality of coating, and defect rate and percent defective are reduced.Simultaneously, because coating is even, can improve speed of production, production efficiency improves and has saved cost.

Accompanying drawing 1 is a structure principle chart of the present invention.
Accompanying drawing 2 is a traditional handicraft schematic diagram of the present invention.
In the above accompanying drawing: 1, conveying device; 2, shower nozzle; 3, brush; 4, induction installation; 5, tank body.
The specific embodiment
Below in conjunction with one of attached Fig. 1 and 2 preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be those skilled in the art will recognize that.
As shown in Figure 1, the spray equipment that a kind of tank body 5 weld seams are used, it comprises a conveying device 1, conveying track along conveying device 1 is provided with the brush 3 that is used to spray the shower nozzle 2 of coating and is positioned at shower nozzle 2 downstreams, this spray equipment also comprises the control device that is used to respond to the induction installation 4 of weld seam and is used to control shower nozzle 2, and described induction installation 4 is electrically connected mutually with described control device.
In the present embodiment, after tank body 5 welding, weld seam is by the exploration of conveying device 1 through induction installation 4, and induction installation 4 is sent to control device with the information of sensing, and control device can be determined the time and the spray amount of spraying by the control to shower nozzle 2.Driving lower tank 5 in conveying device 1 constantly moves, and control device control shower nozzle 2 ejection coating are to the commissure.This shower nozzle 2 is an atomizer 2.Atomizer 2 will have the liquid coating of pressure to be ejected in the air by shower nozzle 2, be vaporific effect and drop on the commissure uniformly.The follow-up brushing through brush 3 again of weld seam after the spraying makes it more even, thereby reaches better coating effect.
The present invention adopts above structure, has improved the quality of coating, and defect rate and percent defective are reduced.Simultaneously, because coating is even, can improve speed of production, production efficiency improves and has saved cost.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
