[0002] In a general automatic painting production line, workpieces to be painted need to go through multiple spraying and cleaning processes before painting, and the cleaning liquid used for cleaning is a variety of different chemical agents. At present, the traditional method is that the workpieces to be cleaned are suspended on a conveying chain, and then the workpieces to be processed are sequentially passed through the juxtaposed spraying devices through the hanging conveying chain, and the nozzles on the branch pipes of the spraying devices spray the cleaning liquid to spray and clean the surface of the workpieces.

[0003] The above cleaning method has good effects and is generally welcomed. However, in the painting production line of appearance decorative plastic parts, the cleaned workpieces need to enter subsequent processes such as an oven and a spray booth. Among them, the hanging conveying chain is used in the spraying and cleaning process, while the ground conveying chain is used in parts such as the oven and the spray booth. Therefore, before entering the oven and the spray booth after coming out of the spraying channel, it is necessary to convert the hanging conveying chain into a ground conveying chain, which increases the costs such as equipment and personnel investment in the aspect of transfer and hanging.

Specific embodiments

[0020] Please refer to Figures 1-5 , a spray device in the form of a ground conveyor, comprising a support plate 1 and a spray shell 2. The number of support plates 1 is two. Two rotating shafts 3 are rotatably connected to the surface of the support plate 1. Two first sprockets 4 are fixed on the surface of the rotating shaft 3. A chain 5 is installed on the surface of the first sprocket 4. A chain plate 6 is fixed on the surface of the chain 5. A water through hole 7 is formed on the surface of the chain plate 6. A drive motor 8 is fixed on the surface of the front support plate 1. The output shaft of the drive motor 8 penetrates through the support plate 1 and is fixed to one side rotating shaft 3. A liquid storage tank 9 is arranged below the spray shell 2. A delivery pump 10 is communicated with the surface of the liquid storage tank 9. The top of the delivery pump 10 is communicated with a shunt pipe 12. A plurality of first spray pipes 11 and second spray pipes 13 are fixed on the inner wall of the spray shell 2. Nozzles 14 are communicated with the surfaces of the first spray pipes 11 and the second spray pipes 13. The shunt pipe 12 penetrates through the spray shell 2 and is communicated with the first spray pipes 11 and the second spray pipes 13;

[0021] When the driving motor 8 starts, it will drive the right rotating shaft 3 to rotate, and the first sprocket 4 on the surface of the rotating shaft 3 will drive the chain 5 to move synchronously, so that the chain plate 6 can move, enabling the workpiece to be cleaned to be conveyed on the surface of the chain plate 6. When the workpiece is conveyed into the spray housing 2, the transfer pump 10 extracts the water flow inside the liquid storage tank 9 and diverts it through the diversion pipe 12 into the first spray pipe 11 and the second spray pipe 13, and then sprays it out through the nozzles 14. Through the first spray pipe 11 and the second spray pipe 13 arranged vertically, the upper water flow can directly act on the surface of the workpiece, and the lower water flow can pass through the water passing holes 7 on the surface of the chain plate 6 and contact the workpiece, so that spraying can be carried out simultaneously from the top and bottom of the workpiece, ensuring that all surfaces of the workpiece, including the difficult-to-reach bottom and gaps, can be fully cleaned and covered, improving the comprehensiveness and efficiency of cleaning. And this double-sided spraying design increases the contact area and acting force between the water and the surface of the workpiece, shortens the time required to achieve the ideal cleaning effect, is conducive to improving production efficiency. Through the above design, it is possible to spray and clean the workpiece without hanging the workpiece, and the workpiece can be directly conveyed to the subsequent processing equipment after spraying and cleaning, thus greatly improving the processing efficiency of the workpiece.

[0022] Further, a blower 15 is provided on one side of the liquid storage tank 9, a drain pipe 16 is fixed to the inner wall of the spray housing 2, and a plurality of air outlets are opened at the bottom of the drain pipe 16; the surface of the blower 15 penetrates through the spray housing 2 through a pipe and is communicated with the drain pipe 16;

[0023] The blower 15 can convey high-pressure air into the drain pipe 16, so that the high-pressure air flow can blow towards the surface of the workpiece being conveyed through the air outlets, thereby enabling preliminary water drainage treatment of the cleaned workpiece and making it easier for the workpiece to be dried subsequently.

[0024] Further, a control valve 17 is connected to the bottom of the spray housing 2, a cleaning tank 18 is connected to the bottom of the control valve 17, and the bottom of the cleaning tank 18 is connected to the top of the liquid storage tank 9;

[0025] The water flow accumulated inside the spray housing 2 can flow into the cleaning tank 18 through the control valve 17, and then flow back to the liquid storage tank 9 from the cleaning tank 18, thereby realizing the recycling of the water flow after spraying.

[0026] Further, a filter screen 19 is fixed to the inner wall of the cleaning tank 18, and a cleaning door 20 is hinged to the surface of the cleaning tank 18;

[0027] The filter screen 19 can filter the water flow entering the cleaning tank 18, effectively intercepting the impurities mixed in the water and preventing the impurities from accumulating inside the liquid storage tank 9.

[0028] Furthermore, a plurality of support shafts 21 are rotatably connected to the surface of the support plate 1, and a second sprocket 22 is fixed to the surface of the support shaft 21. The second sprocket 22 meshes with the surface of the chain 5.

[0029] The combination of the second sprocket 22 and the support shaft 21 can support the chain 5, so that the chain plate 6 at the position inside the spraying shell 2 will not collapse inward.

[0030] Furthermore, the first sprocket 4, the chain 5 and the chain plate 6 are all made of stainless steel.

[0031] Stainless steel has extremely high resistance to a variety of chemical substances, can effectively resist the erosion of corrosive media such as acids, alkalis, and salts, and is suitable for working in an environment containing corrosive components, such as cleaning agents, moist or salty air. It can ensure that the first sprocket 4, the chain 5 and the chain plate 6 have a good service life.

[0032] Furthermore, water baffle curtains 23 are fixed to both the left and right sides of the surface of the spraying shell 2.

[0033] The water baffle curtains 23 can block the splashing water flow and reduce the water flow flying outside the spraying shell 2 during the spraying process.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
