Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 2 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a tank inner wall spraying device, including a support base 1, a spraying component 3, a connecting frame 4, a second rotary motor 5, and a hydraulic lifting rod 7;

[0027] The support base 1 consists of four L-shaped blocks, which are used to stably place the can 2 to be sprayed and to position the can 2. The spraying assembly 3 includes a spray gun 33, a support plate 31, a rotating mechanism 34, and a translation mechanism 35. The support plate 31 is located directly above the opening of the can 2 to be sprayed. In order to avoid the spray gun 33 interfering with the support plate 31 during the angle adjustment process, a U-shaped hole 32 is provided at the center of the support plate 31, and the spray gun 33 is located directly above the U-shaped hole 32.

[0028] The translation mechanism 35 includes a slide block 351, a slider 352, a reinforcing block 353, an electric push rod 354, and a fixing block 355. There are two slide blocks 351, which are symmetrically arranged on both sides of the U-shaped hole 32. The slider 352 is slidably connected to the upper end of the slide block 351. The reinforcing block 353 is arranged on one side of the slider 352. The telescopic end of the electric push rod 354 is connected to the reinforcing block 353, and the fixed end of the electric push rod 354 is connected to the fixing block 355. The fixing block 355 is fixed on the upper surface of the support plate 31. The movement of the slider 355 is controlled by the telescopic movement of the electric push rod 354, thereby adjusting the distance between the spray gun 33 and the side wall of the tank 2.

[0029] The rotating mechanism 34 includes a first rotating motor 341, a driving gear 342, a driven gear 343, and a connecting rod 344. The connecting rods 344 are symmetrically arranged on the outer side of the spray gun 33. One end of the connecting rod 344 is fixedly connected to the outer side of the spray gun 33, and the other end of the connecting rod 344 is rotatably connected to the slider 352 through a bearing ring. The driven gear 343 is sleeved on the outer side of one of the connecting rods 344. The driving gear 342 is meshed above the driven gear 343. The driving gear 342 is connected to the output shaft of the first rotating motor 341. The first rotating motor 341 is fixed on the upper end of the slider 352. The first rotating motor 341 controls the rotation of the driving gear 342, thereby controlling the rotation of the driven gear 343, which in turn drives the connecting rod 344 to rotate, adjusting the spray direction of the spray gun 33, and spraying paint onto the side wall and bottom of the tank 2.

[0030] The connecting frame 4 has a C-shaped structure and is located above the spraying assembly 3. The length of the connecting frame 4 is less than the inner diameter of the tank 2. The lower end of the connecting frame 4 is fixedly connected to the outer side of the support plate 31. The second rotary motor 5 is fixed to the upper end of the fixed plate 6. The output shaft of the second rotary motor 5 passes through the fixed plate 6 and is fixedly connected to the upper end of the connecting frame 4. The output shaft of the second rotary motor 5 coincides with the central axis of the tank 2. The entire spraying assembly 3 is rotated by the second rotary motor 5, so that the spray gun 33 rotates along the central axis of the tank 2 and sprays paint onto the side wall of the tank 2.

[0031] The telescopic end of the hydraulic lifting rod 7 is connected to the upper end face of the fixed plate 6, and the fixed end of the hydraulic lifting rod 7 is connected to the fixed frame 8. The extension and retraction of the hydraulic lifting rod 7 controls the movement of the spray gun 33 along the height direction of the tank 2 to uniformly spray the inner wall of the tank 3. The fixed frame 8 is set on one side of the support base 1, and the bottom of the fixed frame 8 is fixed to the ground. The entire fixed frame 8 has an L-shaped structure. A hydraulic pump 11 and a hydraulic oil tank 12 are set at the upper end of the fixed frame 8. The input end of the hydraulic pump 11 is connected to the output end of the hydraulic oil tank 12 through a pipeline, and the output end of the hydraulic pump 11 is connected to the input end of the hydraulic lifting rod 7 through a pipeline.

[0032] To prevent the pipeline from bending during the rotation of the spraying assembly 3, a placement rack 9 is fixed to the upper side of one side of the connecting frame 4. A storage tank 37 containing paint is fixed on the placement rack 9. A pump 36 is installed at the upper end of the connecting frame 4. One end of the pump 36 is connected to the storage tank 37 through a pipeline, and the other end of the pump 36 is connected to the spray gun 33 through a hose. During the rotation of the entire spraying assembly 3 controlled by the second rotary motor 5, the pump 36 and the storage tank 37 rotate together. To prevent interference between the placement rack 9 and the tank 2 during the descent of the spraying assembly 3 controlled by the hydraulic lifting rod 7, the distance between the fixed position of the placement rack 9 and the bottom of the connecting frame 4 is greater than the depth of the inner hole of the tank 2.

[0033] To improve the connection strength of the placement rack 9, a reinforcing rod 10 is provided between the lower end of the placement rack 9 and the connecting frame 4.

[0034] To achieve automated control, a control system 13 is provided at the lower end of the fixed frame 8. The control system 13 includes a controller and an operation panel electrically connected to the controller. The output end of the controller is electrically connected to the input ends of the first rotary motor 341, the electric push rod 354, the pump 36, the second rotary motor 5, and the hydraulic pump 11, respectively. The operation panel is provided with control buttons for controlling the operation of the first rotary motor 341, the electric push rod 354, the pump 36, the second rotary motor 5, and the hydraulic pump 11.

[0035] In use: Place the tank 2 to be sprayed on the support base 1 for positioning, then control the first rotary motor 341 to start. Under the meshing transmission of the drive gear 342 and the driven gear 343, adjust the tilt angle of the spray gun 33 so that the angle between it and the horizontal line is 15-30°. Then control the extension of the hydraulic lifting rod 7 so that the spray gun 33 drops to the spraying height corresponding to the tank 2. Control the distance between the spray gun 33 and the inner wall of the tank 2 by the electric push rod 354. Then turn on the pump 36 to draw the paint from the storage tank 38 and spray it onto the inner wall of the tank 2 through the spray gun 33. At the same time, turn on the second rotary motor 5 so that the spraying assembly 3 starts to rotate and sprays paint around the inner wall of the tank 2. Continuously control the extension of the hydraulic lifting rod 7 so that the spray gun 33 sprays paint evenly along the height direction of the tank 2.

[0036] After the side wall of the tank 2 is coated, the spraying direction of the spray gun 33 is adjusted by the first rotary motor 341 so that the angle between the spray gun 33 and the vertical direction is 30-45°. At this time, the hydraulic lifting rod 7 stops working, so that there is a certain space between the spray gun 33 and the bottom of the tank 2. The second rotary motor 5 continues to work to control the rotation of the spray gun 33 to spray the coating evenly on the bottom of the tank 2. The spray gun 33 is moved horizontally by the electric push rod 354 to adjust the spraying radius of the spray gun 33 and spray the bottom of the tank 2 evenly.

[0037] This invention enables one-time spraying of the two side walls and bottom of the tank without changing the machine, saving spraying time, ensuring spraying effect, and greatly improving ease of use.

[0038] The parts of the utility model not described in detail are prior art. Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model.
