[0027] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0028] The embodiment of the present application discloses a spraying mechanism for tire mold production.

[0029] Reference Figure 1 and Figure 2 A spraying mechanism for tire mold production includes a conveyor belt 1 and a support frame 2. The support frame 2 is fixed to the conveyor belt 1. A conveyor platform 11 is arranged on the conveyor belt 1. The conveyor belt 1 is used to transport the conveyor platform 11 so that the conveyor platform 11 moves along a preset path. A mold to be sprayed is placed on the conveyor platform 11, and the mold is not shown in the figure. The conveyor platform 11 is used to support the mold. The mold of the present application is mainly a tire mold.

[0030] The support frame 2 is provided with a spray box 21 , a lifting assembly 3 , a dust cover 12 and a stop assembly 4 .

[0031] Reference Figure 1 and Figure 2The spray box 21 is fixedly connected to the support frame 2, the output port of the spray box 21 is connected to a spray pipe 211, one end of the spray pipe 211 away from the spray box 21 is connected to a plurality of nozzles 212, and the spray pipe 211 is built with an automatic valve for opening and closing the nozzle 212. When the transport platform is located directly below the nozzle 212, the lifting assembly 3 drives the spray pipe 211 to move downward, the automatic valve will open, and the nozzle 212 will start to spray the mold.

[0032] Reference Figure 2 and Figure 3 The lifting assembly 3 includes a first driving member 31 and a connecting plate 32. The first driving member 31 is a cylinder. The first driving member 31 is fixed to the support frame 2. The output end of the first driving member 31 is fixedly connected to the connecting plate 32. The connecting plate 32 is detachably connected to the dust cover 12. The dust cover 12 is prism-shaped, hollow inside, and has an opening at the bottom, which is used to cover the mold on the conveying platform 11. The top of the dust cover 12 is detachably connected to the connecting plate 32.

[0033] In this embodiment, the disassembly connection is a bolt connection, and in other embodiments, it can also be a clamping connection. The bolt is a hexagonal head bolt.

[0034] The output end of the first driving member 31 faces the direction of the conveyor belt 1. Therefore, when the lifting assembly 3 drives the spray tube 211 to move toward the conveyor platform 11, the dust cover 12 can cover the mold on the conveyor platform 11. During the spraying process, the dust cover 12 can reduce the dispersion of the spray paint particles.

[0035] Reference Figure 2 and Figure 3 The spray pipe 211 outside the dust cover 12 is made of flexible material, so that when the lifting assembly 3 lifts the dust cover 12, the spray pipe 211 will not interfere with the lifting of the dust cover 12. The spray pipe 211 passes through the connecting plate 32, so that one end with the nozzle 212 is located inside the dust cover 12. A plurality of support blocks 213 are provided on the lower surface of the connecting plate 32, the upper part of the support block 213 is fixedly connected to the connecting plate 32, and the lower part of the support block 213 is sleeved on the spray pipe 211. The spray pipe 211 can be connected to the support pipe, so that when the first driving member 31 drives the connecting plate 32 to move downward, the dust cover 12 and the spray pipe 211 descend synchronously.

[0036] Reference Figure 3 and Figure 4The connecting plate 32 is also provided with an air hole 321, which faces away from the opening direction of the nozzle 212. The opening direction of the nozzle 212 is such that the air hole 321 is located above the nozzle 212. Since the dust cover 12 has covered the mold on the transport platform when the nozzle 212 is spraying the mold, in order to prevent the air pressure from increasing, during the spraying process, the gas in the dust cover 12 will come out from the air hole 321 to keep the air pressure inside the dust cover 12 and the external air pressure stable during operation.

[0037] Reference Figure 3 and Figure 4 The support frame 2 is provided with a dust box 23, the input port of the dust box 23 is connected to a dust pipe 22, the other end of the dust pipe 22 is connected to the dust cover 12, and the position where the dust pipe 22 is connected to the dust cover 12 is lower than the nozzle 212. An exhaust fan is provided in the dust box 23, and the input end of the exhaust fan is connected to the dust pipe 22, so that the dust pipe 22 can generate negative pressure to absorb the paint floating in the dust cover 12. The exhaust fan in this application is a prior art, and the specific connection method and structure are not repeated here, and it is only necessary to achieve that the dust pipe 22 generates negative pressure.

[0038] When the conveyor belt 1 is transporting the conveyor platform 11 , the stopper assembly 4 can limit the conveyor platform 11 from moving on the conveyor belt 1 .

[0039] Reference Figure 4 and Figure 5 The stop assembly 4 includes a second driving member 41 and a stop platform 42. The second driving member 41 is also a cylinder. The output end of the second driving member 41 is fixedly connected to the stop platform 42. The second driving member 41 can drive the stop platform 42 to move toward the conveying platform 11 to limit the conveying platform 11 from moving relative to the conveying frame. The moving direction of the stop platform 42 is perpendicular to the conveying path direction of the conveyor belt 1.

[0040] The stopper 42 has a baffle 421, and the second driving member 41 can drive the stopper 42. As the stopper 42 moves, the baffle 421 is located in the moving path of the conveyor 11. During the movement of the conveyor 11, the conveyor 11 is blocked by the baffle 421. At this time, the conveyor 11 is located just below the dust cover 12. Under the resistance of the baffle 421, the conveyor 11 remains motionless relative to the dust cover 12.

[0041] The stopper 42 also has a pushing portion 422. An extension plate 111 is fixed to the edge of the conveyor 11. The end of the pushing portion 422 facing the conveyor 11 is lower than the extension plate 111, and the end away from the stopper 42 is higher than the extension plate 111. Therefore, as the stopper 42 continues to move in the direction of pushing the conveyor 11, the pushing portion 422 can resist the extension plate 111 and lift the extension plate 111, so that the conveyor 11 moves in the direction of the dust cover 12. At this time, the bottom of the conveyor 11 is no longer in contact with the conveyor belt 1. The conveyor belt 1 no longer drives the conveyor 11 to move, and the upward movement of the conveyor 11 allows the nozzle 212 to approach the mold on the conveyor 11 faster. It can also enable the dust cover 12 to cover the mold on the conveyor 11 faster. The mold is in a sprayed state.

[0042] The conveying platform 11 is provided with a dustproof groove 112, which matches the bottom of the dust cover 12. A sealing ring 113 is detachably provided inside the dustproof groove 112. When the conveying platform 11 is located directly below the dust cover 12, under the action of the lifting assembly 3 and the stop assembly 4, the conveying platform 11 and the dust cover 12 approach each other, and the bottom of the dust cover 12 enters the dustproof groove 112 and abuts against the sealing ring 113, so that the dust cover 12 can cover the mold on the conveying platform 11.

[0043] The implementation principle of the embodiment is as follows: the mold to be sprayed is transferred to the conveyor table 11, and the conveyor belt 1 will drive the conveyor table 11 to move, so that the conveyor table 11 moves toward the support frame 2. The dotted arrow in the figure is the conveying direction of the conveyor belt 1. As the conveyor table 11 moves below the dust cover 12, the baffle 421 will resist the conveyor table 11, so that the conveyor table 11 will no longer move. The lifting component 3 drives the dust cover 12 and the nozzle 212 to move downward, and the stop component 4 drives the conveyor table 11 to move upward. After the dust cover 12 covers the mold of the conveyor table 11, the nozzle 212 starts spraying. After completion, the dust suction pipe 22 can absorb the paint dispersed in the air in the dust cover 12, and then the lifting component 3 is reset to make the dust cover 12 and the nozzle 212 move upward, and the stop component 4 allows the conveyor platform 11 to move downward. After the bottom of the conveyor platform 11 contacts the conveyor belt 1, the pushing part 422 leaves the extension plate 111, and as the stop component 4 continues to reset, the baffle 421 will move away from the conveyor platform 11. When the baffle 421 no longer resists the conveyor platform 11, the conveyor belt 1 will drive the conveyor platform 11 to move, allowing the conveyor platform 11 and the sprayed mold to come out of the support frame 2.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application; therefore, according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the above specific implementation modes and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention. Therefore: All equivalent changes made according to the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
