Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil painting, more specifically, the present application relates to an oil painting drawing spray gun device. BACKGROUND

[0002] Oil painting refers to the process of artists using oil paints to create unique artistic effects and visual impact on the surface of canvas or other materials through specific brush strokes, color matching and composition techniques. In the process of oil painting, spray gun device as an important auxiliary tool can accurately control the amount and range of paint spraying, help artists achieve more delicate and rich picture effect, and improve the overall quality and artistic expression of the work.

[0003] According to the patent document: CN112172404A, a kind of oil painting drawing spray gun device, including gun rack and handle, the handle is fixedly arranged on the outer wall of one side of gun rack, the bottom outer wall of the gun rack is opened with equidistant distribution installation port, and the inner wall of installation port is provided with fixed cover, the inner wall of the fixed cover is threadedly connected with pigment tank, the outer wall of one side of the gun rack is opened with equidistant distribution fixed port, and the inner wall of fixed port is provided with spray pipe, the inside of the gun rack is provided with liquid pump, and the liquid pump is communicated with the one end of spray pipe at liquid discharge end, the liquid pump is communicated with the pigment tank at liquid suction end through liquid suction pipe, the outer wall of the handle is provided with equidistant distribution control switch, the gun rack is provided with protection mechanism, and the gun rack is also provided with anti-misoperation mechanism. The present application effectively avoids the phenomenon that the paint of one spray pipe affects the paint of other spray pipes during the spraying process of the spray pipe, so that the paint mixing phenomenon at the pipe opening of different spray pipes can be avoided, and the practicability is higher.

[0004] During oil painting, multiple colors are needed to enrich the oil painting picture, usually by mixing three primary colors to obtain suitable colors. However, different colors of paint are prone to interfere with each other during spraying, which may cause paint mixing at the pipe opening, affecting the final painting effect. In addition, due to the use of multiple colors of paint during oil painting, the corresponding relationship between different paint tanks and spray pipes lacks effective isolation in the traditional spray gun structure. When the operator switches colors, the paint remaining in the internal channel of the gun rack may flow back to the wrong paint tank through the liquid pump, causing color cross contamination. SUMMARY

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides an oil painting spray gun device. The technical problem to be solved by the present invention is that during the use of the spray gun, different colors of pigments are prone to interfering with each other, which may cause pigment mixing at the nozzle and affect the final painting effect. In addition, when painting with oils, since multiple colors of pigments are used at the same time, the traditional spray gun structure makes it difficult to effectively isolate the correspondence between different pigment tanks and the spray tube.

A cross-shaped turntable 228 is rotatably connected to the top of the outer wall of the toothed disc 224. A connecting upright 229 is fixedly connected to the top of the cross-shaped turntable 228 in a circular array. A top connecting plate 2210 is fixedly connected to the top of the multiple connecting uprights 229. The middle part of the bottom of the top connecting plate 2210 is rotatably connected to the top of the columnar upright 222. A transmission rod 2211 is fixedly connected to the top center of the top connecting plate 2210. A transmission rod drive disc 2212 is fixedly connected to the outer wall of the transmission rod 2211. The outer wall of the transmission rod drive disc 2212 is fitted onto the inner wall of the track 217 on the side away from the drive disc 216. The top of the transmission rod 2211 extends to the top of the top plate 213 and is fixedly connected to a fourth drive disc 2213. The outer wall of the fourth drive disc 2213 is fitted onto the inner wall of the second track 2110 on the side away from the second drive disc 219. A stirring rod control rod 2214 is rotatably connected to the top four sides of the cross turntable 228. Gears 2215 are fixedly connected to the top of each of the multiple stirring rod control rods 2214. The outer walls of the multiple gears 2215 mesh with the four sides of the outer wall of the gear disc 224.Multiple stirring rod control rotors 2214 are fixedly connected to the middle of their outer walls by control rotor transmission discs 2216. Each control rotor transmission disc 2216 has a fourth track 2217 fitted onto its outer wall. A second control rotor 22113 is fitted onto the inner wall of each fourth track 2217 on the side furthest from the control rotor transmission disc 2216. The bottom ends of each second control rotor 22113 are fixedly connected to the top of a cross-shaped turntable 228 on the side outside the multiple stirring rod control rotors 2214. The four sides of the outer wall of the cross-shaped turntable 228 are fixedly connected to the inner side of the outer wall of multiple pigment cans 22112. At the top, the top ends of multiple second control levers 22113 are all fixedly connected to second control lever transmission discs 2218. The outer walls of the multiple second control lever transmission discs 2218 are fitted with fifth tracks 2219. The inner walls of the multiple fifth tracks 2219, on the side away from the second control lever transmission discs 2218, are all fitted with fifth transmission discs 22110. The inner walls of the multiple fifth transmission discs 22110 are all fixedly connected to stirring rods 22111. The bottom ends of the multiple stirring rods 22111 extend through the middle of the top of multiple pigment tanks 22112 to the bottom of the inner wall of the pigment tank 22112. When it is necessary to change the color of the paint sprayed on the main body 1 of the spray gun, the inner walls of the four paint tanks 22112 respectively store cleaning water, red, blue and green. When changing, the motor 215 is started first, and the motor 215 drives the transmission disk 216 to rotate. The transmission disk 216 transmits power to the transmission rod transmission disk 2212 through the track 217, which in turn drives the transmission rod 2211 to rotate. The fourth transmission disk 2213 at the top of the transmission rod 2211 rotates accordingly. Through the second track 2110, the second transmission disk 219 and the columnar vertical rotating rod 218 rotate synchronously. The third transmission disk 2112 at the bottom of the columnar vertical rotating rod 218 transmits power to the nozzle changing mechanism 3 through the third track 2113 to change the nozzle. Meanwhile, the toothed disc 224 at the top of the columnar upright 222 remains stationary. The rotation of the top connecting disc 2210 drives the connecting uprights 229 on the four sides of the bottom to rotate. The rotation of multiple connecting uprights 229 in turn drives the cross disc 228 and the cross disc 228 on its inner wall to rotate together with the collar 226 on the outer wall of the columnar rotating tube 225. In turn, the rotation of the collar 226 and the cross disc 228 drives the four pigment can fixing plates 227 and the pigment cans 22112 on their inner walls to rotate together. During rotation, the gears 2215 at the top of the multiple stirring rod control rods 2214 mesh with the outer wall of the toothed disc 224. Since the toothed disc 224 remains stationary, when the collar 226 drives the pigment cans 22112 to rotate to different angles, the gears 2215 at the top of the stirring rod control rods 2214 will roll along the tooth grooves on the outer wall of the toothed disc 224, thereby driving the stirring rod control rods 2214 to rotate on their own axis. This rotation is achieved through... The second control lever 22113 rotates synchronously through the linkage of the control lever transmission disc 2216 and the fourth track 2217. The power is then transmitted to the fifth transmission disc 22110 via the second control lever transmission disc 2218 and the fifth track 2219. This ultimately drives the stirring rod 22111 to stir the pigment inside the pigment tank 22112, ensuring that the pigment is fully and evenly mixed. This ensures that the pigment can present the best color texture and consistency when painting with the spray gun. When the pigment tank 22112 of the target color rotates to the top of the feed funnel 223, the motor 215 stops running. At this time, the pigment in the pigment tank flows into the inner wall of the spray gun body 1 through the feed funnel 223, completing the pigment replacement process. If it is necessary to clean the pigment residue inside the spray gun body 1, the pigment tank 22112 storing cleaning water is rotated to the top of the feed funnel 223, and cleaning water is injected through the same process for rinsing.

[0022] like Figure 8 - Figure 11As shown, the nozzle replacement mechanism 3 includes a nozzle replacement assembly 31. A nozzle replacement control component 32 is located on the right side of the nozzle replacement assembly 31. The nozzle replacement assembly 31 includes a nozzle connecting collar 311. The rear inner wall of the nozzle connecting collar 311 is fixedly connected to the outer front wall of the spray gun body 1. A side limiting plate 312 is fixedly connected to the left side of the front side of the nozzle connecting collar 311. A columnar rotating rod 313 is located on the right side of the nozzle connecting collar 311. A second gear 314 is fixedly connected to the rear end of the columnar rotating rod 313. A third gear 315 meshes with the outer wall of the second gear 314. A nozzle connecting rod connecting ring 316 is fixedly connected to the outer wall of the columnar rotating rod 313 on one side of the front side of the nozzle connecting collar 311. A nozzle connecting rod 317 is fixedly connected in a ring array to the outer wall of the nozzle connecting rod connecting ring 316. Multiple nozzle connecting rods 317 are fixedly connected to their outer sides. The head replacement control component 32 includes a protective shell 321. The front left side of the protective shell 321 is fixedly connected to the outer wall of the columnar rotating rod 313 on the side behind the nozzle connecting rod connecting ring 316. The front inner wall of the protective shell 321 is rotatably connected to a conical tooth connecting rod 322. The rear end of the conical tooth connecting rod 322 is fixedly connected to a conical tooth 323. The outer wall of the conical tooth 323 meshes with a second conical tooth 324. The top of the second conical tooth 324 is fixedly connected to a conical tooth transmission rod 325. The top end of the conical tooth transmission rod 325 extends to the top of the protective shell 321 and is fixedly connected to a sixth transmission disc 326. The outer wall of the sixth transmission disc 326 is sleeved on the inner wall of the third track 2113 on the side away from the third transmission disc 2112. The rear outer wall of the conical tooth 323 is rotatably connected to the front inner wall of the protective shell 321. The front outer wall of the conical tooth connecting rod 322 is fixedly connected to the inner wall of the third gear 315. While changing the pigment, the sixth transmission disc 326 is driven to rotate simultaneously via the third transmission disc 2112 and the third track 2113. The rotation of the sixth transmission disc 326 drives the conical gear transmission rod 325 to rotate synchronously, which in turn drives the second conical gear 324 to rotate. The meshing of the second conical gear 324 and the conical gear 323 causes the conical gear connecting rod 322 to rotate accordingly. The conical gear connecting rod 322 then drives the third gear 315 to rotate. The third gear 315 meshes with the second gear 314, thereby driving the cylindrical rotating rod 313 to rotate. The rotation of the columnar rotating rod 313 causes the nozzle connecting rod connecting ring 316 to drive multiple nozzle connecting rods 317 and the nozzles 318 fixedly connected to their outer ends to rotate synchronously. When the required nozzle rotates to the position corresponding to the nozzle of the spray gun body 1 and the corresponding paint tank 22112 rotates to the corresponding position, the motor 215 stops running. At this time, the nozzle replacement is completed, ensuring that a suitable nozzle can be used for oil painting after changing the paint, so as to adapt to different paint characteristics and painting needs, and improve the quality and effect of oil painting.

[0023] Working principle of this invention: When it is necessary to change the pigment color sprayed by the main body 1 of the spray gun, the inner walls of the four pigment tanks 22112 respectively store cleaning water, red, blue and green. During replacement, the motor 215 is first started, driving the transmission disc 216 to rotate. The transmission disc 216 transmits power to the transmission rod 2212 via the track 217, which in turn drives the transmission rod 2211 to rotate. The fourth transmission disc 2213 at the top of the transmission rod 2211 rotates accordingly, driving the second transmission disc 219 and the columnar rotating rod 218 to rotate synchronously via the second track 2110. The third transmission disc 2112 at the bottom of the columnar rotating rod 218 drives the sixth transmission disc 326 to rotate simultaneously via the third track 2113. The rotating drive conical tooth transmission rod 325 rotates synchronously, which in turn drives the second conical tooth 324 to rotate. The meshing action of the second conical tooth 324 and the conical tooth 323 causes the conical tooth connecting rod 322 to rotate accordingly. The conical tooth connecting rod 322 then drives the third gear 315 to rotate. The third gear 315 meshes with the second gear 314, thereby driving the columnar rotating rod 313 to rotate. The rotation of the columnar rotating rod 313 causes the nozzle connecting rod connecting ring 316 to drive multiple nozzle connecting rods 317 and the nozzles 318 fixedly connected to their outer ends to rotate synchronously. At the same time, the toothed disc 224 at the top of the columnar upright rod 222 remains stationary. The rotation of the top connecting disc 2210 drives the connecting upright rods 229 on the four sides of the bottom to rotate. The rotation of multiple connecting upright rods 229 in turn drives the ten The rotary disc 228, along with the cross disc 228 on its inner wall and the collar 226 on the outer wall of the cylindrical rotating tube 225, rotate together. This rotation, in turn, causes the four pigment can fixing plates 227 and the pigment cans 22112 on their inner walls to rotate. During rotation, the gears 2215 at the top of the multiple stirring rod control rods 2214 mesh with the outer wall of the gear disc 224. Since the gear disc 224 remains stationary, when the collar 226 rotates the pigment cans 22112 to different angles, the gears 2215 at the top of the stirring rod control rods 2214 roll along the tooth grooves on the outer wall of the gear disc 224, thereby driving the stirring rod control rods 2214 to rotate. This rotation is controlled by the rod transmission disc 2216 and the fourth track 2217. The linkage causes the second control lever 22113 to rotate synchronously, and then the power is transmitted to the fifth transmission disc 22110 via the second control lever transmission disc 2218 and the fifth track 2219. Finally, the stirring rod 22111 drives the stirring action inside the paint tank 22112 to mix the paint thoroughly and evenly, ensuring that the paint can present the best color texture and consistency when painting with the spray gun. When the required nozzle rotates to the position corresponding to the nozzle of the spray gun body 1 and the corresponding paint tank 22112 rotates to the corresponding position, the motor 215 stops running. At this time, the replacement of the nozzle and paint is completed.
