[0010] A spraying device with an automatic surface changing function comprises: a base, a spraying pipe is provided on the base, the spraying pipe is connected to the base through a bracket, a feed port and a discharge port are respectively provided at both ends of the spraying pipe, a grinding device is provided on the side of the spraying pipe close to the feed port, a spraying device is provided on the side of the spraying pipe close to the discharge port, a plurality of rotating rollers are provided on the inner wall of the feed port, the plurality of rotating rollers are arranged around the axis of the feed port, the rotating rollers are arranged obliquely, and the rotating rollers are driven by a micro motor, the grinding device comprises a grinding chamber, the grinding chamber is provided in the spraying pipe, and the spraying device comprises: a spraying chamber, the spraying chamber is provided in the spraying pipe;

[0011] The staff feeds the workpiece into the spraying pipe, and the workpiece enters the spraying pipe through the feed port. After the workpiece enters, the controller controls the micro motor in the feed port to start, and the drive shaft in the micro motor drives the rotating roller to rotate. Since the rotating roller is arranged obliquely, the rotating roller contacts the surface of the workpiece when rotating. During the rotation of the rotating roller, the rotating roller drives the workpiece to rotate, thereby realizing automatic surface changing of the workpiece. Then the workpiece moves to the side close to the discharge port, and the workpiece rotates and moves to the side close to the grinding chamber. When the workpiece enters the grinding chamber, the controller controls the grinding device to start, and the grinding device immediately grinds the surface of the workpiece. The grinding device grinds the outer wall of the workpiece flat, thereby improving the adhesion of the spray coating on the surface of the workpiece, thereby improving the quality of the spray coating on the surface of the workpiece; when the workpiece is polished, the workpiece moves to the side close to the spray chamber. When the workpiece enters the spray chamber, the controller controls the spray device to start, and the spray device immediately sprays the surface of the workpiece. The workpiece is sprayed during its rotation, which improves the efficiency of spraying and thereby improves the quality of spraying. After spraying is completed, the workpiece is output from the discharge port.

[0012] Preferably, two conical tubes are provided in the polishing chamber, and the two conical tubes are symmetrically arranged at both ends of the polishing chamber, one of the conical tubes is close to the feed port, and the other conical tube is close to the spraying chamber. Several polishing plates are provided at the center of the polishing chamber, and the several polishing plates are arranged around the axis of the polishing chamber.

[0013] Preferably, an air delivery cavity is provided on the side of the spraying tube close to the polishing cavity, an air pump is provided on the base, the air delivery cavity is connected to the air pump through a pipeline, the air pump is connected to an external air source through a pipeline, and a plurality of air outlet pipes are provided in the conical tube on the side close to the feed port, and the plurality of air outlet pipes are arranged around the axis of the conical tube, one end of the air outlet pipe is connected to the air delivery cavity, and the other end of the air outlet pipe is connected to the polishing cavity, the polishing rod in the polishing plate passes through the polishing cavity, and the polishing rod in the polishing plate extends into the air delivery cavity, and the polishing rod in the polishing plate is a flexible rod.

[0014] Preferably, a dust collecting chamber is opened in the conical tube near the spraying chamber side, the dust collecting chamber is connected to the polishing chamber, a collecting box is provided on the base, the dust collecting chamber is connected to the collecting box through a pipe, and a plurality of conveying rollers are provided on the inner wall of the conical tube near the spraying chamber side, and the plurality of conveying rollers are arranged around the axis of the conical tube, and the conveying rollers are driven by a micro motor.

[0015] Preferably, a rotating ring is provided on the outer ring of the conical tube near the spray chamber side, the rotating ring is rotatably connected to the conical tube, a plurality of paddles are provided on the side of the rotating ring near the grinding plate, the plurality of paddles are arranged around the axis of the conical tube, the paddles are connected to the rotating ring, and an electromagnetic coil is provided on the side of the rotating ring away from the gas delivery chamber;

[0016] After the workpiece enters the spraying pipe through the feed port, the workpiece moves to the side close to the grinding chamber. During the movement of the workpiece, it first contacts the inner wall of the tapered tube close to the feed port, and then moves to the bottom of the grinding plate. The controller controls the air pump in the base to start, and the air pump immediately extracts the outside air and delivers it to the gas delivery cavity through the pipeline. Then the gas is blown from the side close to the discharge port to the feed port. During the gas delivery process, the gas flows through the nozzle, and turbulence will be generated after the gas passes through the nozzle. The turbulent flow continues to flow to the side close to the grinding rod in the grinding plate. When the turbulent flow hits the grinding rod, since the grinding rod is a flexible rod, the grinding rod is affected by the turbulent flow. Under the action of the grinding rod, the grinding plate swings, and the swing is transmitted to the grinding plate through the grinding rod, and the grinding plate also swings. During the swinging process, the grinding plate contacts the surface of the workpiece, so that the burrs on the surface of the workpiece are polished flat, thereby increasing the adhesion of the spray liquid, thereby improving the quality of the spraying on the workpiece surface. After the gas flows through the grinding rod, it continues to flow to the side close to the outlet pipe. The gas flows into the grinding chamber through the outlet pipe, and the gas is ejected outward from the outlet pipe. The ejected gas flows through the surface of the grinding plate and the workpiece, and the gas immediately cleans the debris on the surface of the grinding plate and the workpiece to prevent the debris from adhering to the surface of the workpiece, thereby affecting the subsequent spraying effect.

[0017] During the debris cleaning process, the controller controls the electromagnetic coil inside the conical tube near the spray chamber to be energized. When the electromagnetic coil is energized, it generates magnetic force, and the debris moves along the gas to the side near the dust collecting chamber. Since the outer wall of the conical tube is in an arc shape, the gas drives the debris to move along the outer wall of the conical tube. Due to the magnetic force generated by the electromagnetic coil, the debris will be adsorbed on the outer wall of the conical tube near the spray chamber. At this time, the rotating ring rotates under the influence of the magnetic force. During the rotation of the rotating ring, the rotating ring drives the paddle to rotate. During the rotation of the paddle, the paddle will pry the debris adsorbed on the outer wall of the conical tube, so that the debris moves to the side near the dust collecting chamber, so that the debris finally falls into the dust collecting chamber, and finally the debris is transported from the dust collecting chamber to the collection box through the pipeline;

[0018] After the workpiece is polished, it continues to move toward the spray chamber. When the workpiece moves, it passes through the tapered tube close to the spray chamber. Due to the magnetic force generated by the electromagnetic coil, the electromagnetic coil generates a large amount of heat. The heat is transferred to the surface of the workpiece through the tapered tube, causing the temperature of the workpiece surface to rise, thereby improving the quality of subsequent spraying.

[0019] Preferably, a plurality of nozzles are provided inside the spray chamber, and the plurality of nozzles are arranged around the axis of the spray chamber. A nozzle is provided on the side of the nozzle close to the spray pipe, and the nozzle is connected to the nozzle. A spray ring is provided on the outer wall of the spray pipe. The spray ring is a hollow structure, and the spray ring is filled with spray liquid. A pump is provided in the spray ring, and the nozzle passes through the air delivery chamber to connect to the spray ring.

[0020] Preferably, the spray coverage area of ​​each nozzle is 30°.

[0021] Preferably, the diameters of the feed port and the tapered tube are smaller than the diameters of the spray chamber and the discharge port;

[0022] When the polished workpiece enters the spray chamber, the controller controls the pump in the spray ring to start, and the pump transports the spray liquid in the spray ring, and the spray liquid is then transported to the nozzle. The spray liquid enters the nozzle through the nozzle. Since the spray coverage area of ​​the nozzle is 30° and the workpiece rotates, the spray liquid is sprayed on the surface of the workpiece faster. As the workpiece moves to the spray chamber, the workpiece is affected by the heat generated by the electromagnetic coil, and the temperature of the workpiece surface rises. After the spray liquid is sprayed on the surface of the workpiece, the spray liquid is affected by the heat and the spray The water molecules in the liquid are evaporated, so that the spray liquid is quickly solidified and formed on the surface of the workpiece, which improves the efficiency of the spray liquid solidification and avoids the phenomenon of sagging of the spray liquid, thereby improving the quality of the workpiece surface spraying. Since the diameter of the feed port and the tapered tube is smaller than the diameter of the spray chamber and the discharge port, the sprayed workpiece is prevented from contacting the spray liquid with the inner wall of the spray tube during the process of being transported to the discharge port, thereby avoiding the contact between the spray liquid and the inside of the spray tube, which causes the spray liquid on the workpiece surface to be scratched, further improving the efficiency of the workpiece surface spraying.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. During the gas delivery process, the gas flows through the nozzle, and turbulence will be generated after the gas passes through the nozzle. The turbulent flow continues to flow toward the side close to the grinding rod in the grinding plate. When the turbulent flow hits the grinding rod, the grinding rod is a flexible rod, so the grinding rod swings under the action of the turbulent flow, and the swing is transmitted to the grinding plate through the grinding rod, and the grinding plate also swings. During the swinging process, the grinding plate contacts the surface of the workpiece, so that the burrs on the surface of the workpiece are polished smooth, thereby increasing the adhesion of the spray liquid, thereby improving the quality of the spraying on the workpiece surface.

[0025] 2. As the workpiece moves toward the spray chamber, it is affected by the heat generated by the electromagnetic coil, and the temperature of the workpiece surface rises. After the spray liquid is sprayed on the surface of the workpiece, the spray liquid is affected by the heat, and the water molecules in the spray liquid are evaporated, causing the spray liquid to quickly solidify and form on the surface of the workpiece, thereby improving the efficiency of the spray liquid solidification and forming, avoiding the phenomenon of sagging of the spray liquid, and thus improving the quality of the workpiece surface spraying. Since the diameter of the feed port and the tapered tube is smaller than the diameter of the spray chamber and the discharge port, the sprayed workpiece is prevented from contacting the spray liquid with the inner wall of the spray tube during the process of being transported to the discharge port, thereby avoiding the phenomenon of scratching of the spray liquid on the workpiece surface after the spray liquid contacts the inside of the spray tube, further improving the efficiency of the workpiece surface spraying.

[0041] As a specific embodiment of the present invention, a dust collecting chamber 26 is opened in the conical tube 22 near the spraying chamber 31, and the dust collecting chamber 26 is connected to the polishing chamber 21. A collecting box is provided on the base 1, and the dust collecting chamber 26 is connected to the collecting box through a pipe. A plurality of conveying rollers 27 are provided on the inner wall of the conical tube 22 near the spraying chamber 31. The plurality of conveying rollers 27 are arranged around the axis of the conical tube 22, and the conveying rollers 27 are driven by a micro motor.

[0042] As a specific embodiment of the present invention, a rotating ring 28 is provided on the outer ring of the tapered tube 22 near the spray chamber 31. The rotating ring 28 is rotatably connected to the tapered tube 22. A plurality of paddles 29 are provided on the side of the rotating ring 28 near the grinding plate 23. The plurality of paddles 29 are arranged around the axis of the tapered tube 22. The paddles 29 are connected to the rotating ring 28. An electromagnetic coil is provided on the side of the rotating ring 28 away from the gas delivery chamber 24.

[0043] After the workpiece enters the spraying pipe 11 through the feed port 12, the workpiece moves to the side close to the grinding chamber 21. During the movement of the workpiece, it first contacts the inner wall of the tapered tube 22 close to the feed port 12. Then the workpiece moves to the bottom of the grinding plate 23. The controller controls the air pump in the base 1 to start. The air pump immediately extracts the outside air and delivers it to the gas delivery chamber 24 through the pipeline. Then the gas is blown from the side close to the discharge port 13 to the feed port 12. During the gas delivery process, the gas flows through the nozzle 33. After the gas passes through the nozzle 33, turbulence will be generated. The turbulent flow continues to flow to the side close to the grinding rod in the grinding plate 23. When the turbulent flow hits the grinding rod During the operation, since the grinding rod is a flexible rod, it swings under the action of turbulence, and the swing is transmitted to the grinding plate 23 through the grinding rod, and the grinding plate 23 also swings. During the swinging process, the grinding plate 23 contacts the surface of the workpiece, so that the burrs on the surface of the workpiece are polished flat. After the gas flows through the grinding rod, it continues to flow to the side close to the outlet pipe 25. The gas flows into the grinding chamber 21 through the outlet pipe 25, and the gas is ejected outward from the outlet pipe 25. The ejected gas flows through the grinding plate 23 and the surface of the workpiece, and the gas immediately cleans the debris on the grinding plate 23 and the surface of the workpiece to prevent the debris from adhering to the surface of the workpiece and affecting the subsequent spraying effect.

[0044] During the debris cleaning process, the controller controls the electromagnetic coil inside the conical tube 22 near the spray chamber 31 to be energized. When the electromagnetic coil is energized, a magnetic force is generated, and the debris moves along the gas to the side near the dust collecting chamber 26. Since the outer wall of the conical tube 22 is in an arc shape, the gas drives the debris to move along the outer wall of the conical tube 22. Due to the magnetic force generated by the electromagnetic coil, the debris will be adsorbed on the outer wall of the conical tube 22 near the spray chamber 31. At this time, the rotating ring 28 rotates under the influence of the magnetic force. During the rotation of the rotating ring 28, the rotating ring 28 drives the paddle 29 to rotate. During the rotation of the paddle 29, the paddle 29 will pry the debris adsorbed on the outer wall of the conical tube 22, so that the debris moves to the side near the dust collecting chamber 26. The debris will fall into the dust collecting chamber 26 and finally the debris is transported from the dust collecting chamber 26 to the collection box through the pipeline.

[0045] As the workpiece continues to move toward the spray chamber 31 after grinding, it passes through the tapered tube 22 close to the spray chamber 31. Due to the magnetic force generated by the electromagnetic coil, a large amount of heat is generated by the electromagnetic coil. The heat is transferred to the surface of the workpiece through the tapered tube 22, causing the surface temperature of the workpiece to rise.

[0046] As a specific embodiment of the present invention, a plurality of nozzles 32 are provided inside the spray chamber 31, and the plurality of nozzles 32 are arranged around the axis of the spray chamber 31. A nozzle 33 is provided on the side of the nozzle 32 close to the spray pipe 11, and the nozzle 33 is connected to the nozzle 32. A spray ring 34 is provided on the outer wall of the spray pipe 11. The spray ring 34 is a hollow structure, and the spray ring 34 is filled with spray liquid. A pump is provided in the spray ring 34, and the nozzle 33 passes through the air delivery chamber 24 and is connected to the spray ring 34.

[0047] As a specific embodiment of the present invention, the spray coverage area of ​​each nozzle 32 is 30°.

[0048] As a specific embodiment of the present invention, the diameters of the feed port 12 and the tapered tube 22 are smaller than the diameters of the spray chamber 31 and the discharge port 13;

[0049] When the polished workpiece enters the spray chamber 31, the controller controls the pump in the spray ring 34 to start, and the pump transports the spray liquid in the spray ring 34, and the spray liquid is then transported to the nozzle 33, and the spray liquid enters the nozzle 32 through the nozzle 33. Since the spray coverage area of ​​the nozzle 32 is 30 degrees and the workpiece rotates, the spray liquid is sprayed on the surface of the workpiece more quickly. Since the workpiece is affected by the heat generated by the electromagnetic coil during its movement to the spray chamber 31, the temperature of the workpiece surface rises. When the spray liquid After being sprayed on the surface of the workpiece, the spraying liquid is affected by the heat, and the water molecules in the spraying liquid are evaporated, so that the spraying liquid is quickly solidified and formed on the surface of the workpiece, avoiding the phenomenon of the spraying liquid dripping. Since the diameter of the feed port 12 and the tapered tube 22 is smaller than the diameter of the spraying chamber 31 and the discharge port 13, the sprayed workpiece is prevented from contacting the inner wall of the spraying tube 11 during the process of being transported to the discharge port 13, thereby avoiding the spraying liquid on the surface of the workpiece being scratched after contacting the inside of the spraying tube 11.

[0050] Working principle of the present invention:

[0051] The staff feeds the workpiece into the spraying pipe 11, and the workpiece enters the spraying pipe 11 through the feed port 12. After the workpiece enters, the controller controls the micro motor in the feed port 12 to start, and the drive shaft in the micro motor drives the rotating roller 121 to rotate. Since the rotating roller 121 is arranged obliquely, the rotating roller 121 contacts the surface of the workpiece when rotating. During the rotation of the rotating roller 121, the rotating roller 121 drives the workpiece to rotate, thereby realizing automatic surface changing of the workpiece. Subsequently, the workpiece moves to the side close to the discharge port 13, and the workpiece rotates and moves to the side close to the grinding chamber 21;

[0052] After the workpiece enters the spraying pipe 11 through the feed port 12, the workpiece moves to the side close to the grinding chamber 21. During the movement of the workpiece, it first contacts the inner wall of the tapered tube 22 close to the feed port 12. Then the workpiece moves to the bottom of the grinding plate 23. The controller controls the air pump in the base 1 to start. The air pump immediately extracts the outside air and delivers it to the gas delivery chamber 24 through the pipeline. Then the gas is blown from the side close to the discharge port 13 to the feed port 12. During the gas delivery process, the gas flows through the nozzle 33. After the gas passes through the nozzle 33, turbulence will be generated. The turbulent flow continues to flow to the side close to the grinding rod in the grinding plate 23. When the turbulent flow hits the grinding rod Since the grinding rod is a flexible rod, it swings under the action of turbulence, and the swing is transmitted to the grinding plate 23 through the grinding rod, and the grinding plate 23 also swings immediately. During the swinging process, the grinding plate 23 contacts the surface of the workpiece, so that the burrs on the surface of the workpiece are polished flat. After the gas flows through the grinding rod, it continues to flow to the side close to the outlet pipe 25. The gas flows into the grinding chamber 21 through the outlet pipe 25, and the gas is ejected outward from the outlet pipe 25. The ejected gas flows through the grinding plate 23 and the surface of the workpiece, and the gas immediately cleans the debris on the grinding plate 23 and the surface of the workpiece to prevent the debris from adhering to the surface of the workpiece, thereby affecting the subsequent spraying effect.

[0053] During the debris cleaning process, the controller controls the electromagnetic coil inside the conical tube 22 near the spray chamber 31 to be energized. When the electromagnetic coil is energized, a magnetic force is generated, and the debris moves along the gas to the side near the dust collecting chamber 26. Since the outer wall of the conical tube 22 is in an arc shape, the gas drives the debris to move along the outer wall of the conical tube 22. Due to the magnetic force generated by the electromagnetic coil, the debris will be adsorbed on the outer wall of the conical tube 22 near the spray chamber 31. At this time, the rotating ring 28 rotates under the influence of the magnetic force. During the rotation of the rotating ring 28, the rotating ring 28 drives the paddle 29 to rotate. During the rotation of the paddle 29, the paddle 29 will pry the debris adsorbed on the outer wall of the conical tube 22, so that the debris moves to the side near the dust collecting chamber 26. The debris will fall into the dust collecting chamber 26 and finally the debris is transported from the dust collecting chamber 26 to the collection box through the pipeline.

[0054] After the workpiece is polished, it continues to move toward the spray chamber 31. When the workpiece moves, it passes through the tapered tube 22 near the spray chamber 31. Due to the magnetic force generated by the electromagnetic coil, the electromagnetic coil generates a large amount of heat. The heat is transferred to the surface of the workpiece through the tapered tube 22, causing the temperature of the workpiece surface to rise.

[0055] When the polished workpiece enters the spray chamber 31, the controller controls the pump in the spray ring 34 to start, and the pump transports the spray liquid in the spray ring 34, and the spray liquid is then transported to the nozzle 33, and the spray liquid enters the nozzle 32 through the nozzle 33. Since the spray coverage area of ​​the nozzle 32 is 30 degrees and the workpiece rotates, the spray liquid is sprayed on the surface of the workpiece faster. Since the workpiece is moving towards the spray chamber 31, the workpiece is affected by the heat generated by the electromagnetic coil, and the temperature of the workpiece surface rises. When the spray liquid After being sprayed on the surface of the workpiece, the spraying liquid is affected by the heat, and the water molecules in the spraying liquid are evaporated, so that the spraying liquid is quickly solidified and formed on the surface of the workpiece, avoiding the phenomenon of the spraying liquid dripping. Since the diameter of the feed port 12 and the tapered tube 22 is smaller than the diameter of the spraying chamber 31 and the discharge port 13, the sprayed workpiece is prevented from contacting the inner wall of the spraying tube 11 during the process of being transported to the discharge port 13, thereby avoiding the spraying liquid on the surface of the workpiece being scratched after contacting the inside of the spraying tube 11.
