Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached Figures 1-5 drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As shown in the figure, a painting device for the production of speed reducers includes a frame 1. A conveyor belt 2 and a painting mechanism 3 are arranged on the frame 1. The painting mechanism 3 includes a painting chamber 31, a lifting column 32, a mounting plate 33, a painting pipe 34, and a paint nozzle 35. The painting chamber 31 is arranged on the frame 1 above the conveyor belt 2. The lifting column 32 is longitudinally movably inserted through the top plate of the painting chamber 31 and is in transmission connection with a first driving source arranged on the painting chamber 31. The mounting plate 33 is arranged at the lower end of the lifting column 32 inside the painting chamber 31. A plurality of the painting pipes 34 are erected on the mounting plate 33 and are annularly arranged along the center of the mounting plate 33. The paint nozzle 35 is arranged at the lower end of the painting pipe 34, and the port of the paint nozzle 35 faces the axis of the mounting plate 33.

[0024] Specifically, the structure in which the lifting column 32 is longitudinally movably inserted through the top plate of the painting chamber 31 and is in transmission connection with the first driving source: A plurality of erected guide rods 37 are fixedly arranged on the lifting column 32. The guide rods 37 are inserted through the top plate of the painting chamber 31. A thread is formed on the circumferential side surface of the lifting column 32. A transmission sleeve 38 screwed onto the lifting column 32 is rotatably arranged on the top plate of the painting chamber 31. The first driving source is a motor 36. The motor 36 is in transmission connection with the transmission sleeve 38 through the cooperation of a synchronous belt and a synchronous pulley. Through the above structure, the motor 36 drives the transmission sleeve 38 to rotate through the cooperation of the synchronous belt and the synchronous pulley. The transmission sleeve 38 drives the lifting column 32 to longitudinally move on the top plate of the painting chamber 31 under the guiding action of the guide rods 37 through the thread cooperation with the lifting column 32.

[0025] In the above embodiment, a plurality of paint spraying tubes 34 are connected to an external paint supply device through a hose. The paint supply device is a prior art and will not be described in detail here. The reducer housing to be painted is placed on the conveyor belt 2. The conveyor belt 2 carries the reducer housing toward the paint spraying mechanism 3 so that the reducer housing enters the paint spraying room 31 and is located below the mounting plate 33. The motor 36 drives the lifting column 32 to move downward. The lifting column 32 drives the mounting plate 33 and the paint spraying tube 34 on the mounting plate 33 to move downward, so that the paint spraying tube 34 and the paint spraying nozzle 35 are moved to the peripheral side of the reducer housing. At the same time, the paint supply device transports paint to the paint spraying tube 34. Water causes paint to be sprayed out from the paint spray nozzle 35 and sprayed toward the reducer housing. In conjunction with the movement of the paint spray nozzle 35, the paint sprayed from the paint spray nozzle 35 toward the reducer housing fully covers the reducer housing from top to bottom, thereby achieving the painting operation of the reducer housing. The painted reducer housing leaves the paint spraying room 31 along with the conveyor belt 2. Through the above-mentioned structure and method, when performing the painting operation of the reducer housing, it is only necessary to place the reducer housing on the conveyor belt 2 to achieve the comprehensive painting operation of the reducer housing. The operation is convenient, and the coverage of the paint is sufficient, thereby ensuring the quality of the paint spraying, which is beneficial to saving manpower and improving production efficiency.

[0026] Preferably, the mounting plate 33 is provided with a plurality of adjustment grooves 332 extending radially along the mounting plate 33 and matching with the paint spray tube 34, a limiting ring 341 is formed on the peripheral side of the paint spray tube 34, and a limiting step 333 matching with the limiting ring 341 is formed on the lower end of the adjusting groove 332. The upper end of the paint spray tube 34 passes through the adjusting groove 332 and is screwed with a fastening nut 342 to keep the limiting ring 341 on the limiting step 333. The fastening nut 342 cooperates with the limiting ring 341 to vertically fix the paint spray tube 34 on the mounting plate 33. Through the above structure, loosening the fastening nut 342 can make the paint spray tube 34 slide in the adjusting groove 332, thereby adjusting the distance between the paint spray nozzle 35 and the reducer housing during the painting operation, and adapting to reducer housings of different specifications, saving paint water while ensuring the painting effect.

[0027] Preferably, the interior of the lifting column 32 is hollow to form a tube-penetrating cavity 321, and a plurality of tube-penetrating holes 322 that are connected to the tube-penetrating cavity 321 and correspond one-to-one to a plurality of paint spray pipes 34 are opened on the side surface of the lifting column 32. After one end of the hose connecting the paint spray pipe 34 and the paint supply equipment is connected to the paint spray pipe 34, the other end passes through the tube-penetrating hole 322 and extends into the tube-penetrating cavity 321, and then passes through the tube-penetrating cavity 321 and is connected to the paint supply equipment, which facilitates the wiring arrangement of the hose and avoids interference of the hose with the movement of the paint spray mechanism 3 during operation.

[0028] Further, the mounting disc 33 is rotatably arranged at the lower end of the lifting column 32, and a vertical transmission rod 331 is fixedly arranged on the mounting disc 33. A swing cylinder 39 is hinged on the lifting column 32, and the output shaft of the swing cylinder 39 is rotatably connected to the transmission rod 331.

[0029] In the above preferred embodiment, when the mounting disc 33 drives the paint spraying pipe 34 and the paint spraying nozzle 35 to longitudinally move for painting the speed reducer housing, the swing cylinder 39 drives the mounting disc 33 to reciprocally swing on the lifting column 32 through the transmission rod 331. The mounting disc 33 drives the paint spraying pipe 34 and the paint spraying nozzle 35 to reciprocally swing, so that the paint water sprayed from the paint spraying nozzle 35 is sprayed onto the speed reducer housing in a sweeping spray form, making the painting coverage area more sufficient, achieving a better painting effect, and the sweeping spray method is beneficial to saving paint water.

[0030] Furthermore, a drying mechanism 5 is arranged on the frame 1 behind the painting mechanism 3. The drying mechanism 5 includes a drying chamber 51 and a hot air blower 52. The drying chamber 51 is arranged on the frame 1 above the conveyor belt 2, and the hot air blower 52 is arranged on the top plate of the drying chamber 51 and is communicated with the inside of the drying chamber 51. The hot air blower 52 is a prior art, and its specific structure will not be described in detail here.

[0031] In the above preferred embodiment, the speed reducer housing after painting moves towards the drying mechanism 5 under the drive of the conveyor belt 2 and enters the drying chamber 51. The hot air blower 52 works to convey hot air into the drying chamber 51 to dry the speed reducer housing after painting, accelerating the drying speed of the paint water, thereby improving the production efficiency.

[0032] Preferably, a transition chamber 4 is arranged on the frame 1 between the painting chamber 31 and the drying chamber 51, and both ends of the transition chamber 4 are respectively communicated with the painting chamber 31 and the drying chamber 51. The transition chamber 4 plays a transitional role between the painting chamber 31 and the drying chamber 51, avoiding interference between the painting operation and the drying operation, and thus ensuring the painting and drying effects.

[0033] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
