Description

Technical Field

[0001] The present invention belongs to the technical field of tank processing, and specifically relates to an automatic uniform spraying device for the interior of a tank. Background Technique

[0002] The invention patent with the publication number CN114289234A discloses a method for simultaneously spraying the inner and outer surfaces of an iron tank, including a base. On both sides of the top of the base, there are fixed columns. At the top of the base, there is a driving motor. The output end of the driving motor is fixedly connected to a placement table. On one side of the column, there is a drying fan. At the top of the column, there is a top plate fixedly connected. At the bottom of the top plate, there is a cylinder; this method for simultaneously spraying the inner and outer surfaces of an iron tank adjusts the device according to the size of the iron tank. The sleeve block can slide outside the fixed rod and can be fixed with an adjusting bolt after sliding to a suitable position. Then, the cylinder moves the fixed rod into the iron tank. The first spray head at the bottom of the fixed rod sprays paint inside the iron tank, and the second spray head sprays paint outside the iron tank. During the spraying process, the iron tank rotates at a constant speed, thereby achieving uniform spraying. This device realizes simultaneous spraying inside and outside, improves the spraying efficiency, and solves the problems of small spraying range and low efficiency. However, when this device sprays the tank, the tank is directly placed on the placement table, resulting in low stability during the tank processing. At the same time, during the process of spraying paint inside the tank, the atomized paint directly enters the air and pollutes the environment, and the device has a low uniformity in spraying the inside of the tank. Therefore, it needs to be improved. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic uniform spraying device for the interior of a tank to solve the problems mentioned in the background technique.

The pressure bar 27 is slidably connected with the base 1. The pressure bar 27 is welded with the pressure ring 28. The pressure ring 28 is slidably connected with the cushion ring 4. By bringing the tank body 3 into contact with the suction cup 22 and pressing down the suction cup 22, and discharging the air inside the cylinder body 21 by moving the piston 23, the cylinder body 21 is adsorbed by the suction cup 22, so that the tank body 3 is convenient to fix inside the device.

[0030] Among them, one end of the spring 24 is fixedly connected with the piston 23, and the other end of the spring 24 is fixedly connected with the cylinder body 21. By arranging the spring 24, the piston 23 is convenient to reset.

[0031] Among them, the driving mechanism 8 includes a toothed ring 81, a motor 82, a rotating shaft 83, a connecting sleeve 84, a limit pin 85, a gear 86, a cylinder 87, a cylinder rod 88, a guide seat 89, a support ring 810, and a convex block 811. The outside of the liquid inlet pipe 6 is fixedly sleeved with the toothed ring 81. The motor 82 is fixedly installed on the frame 5. The rotating shaft 83 of the motor 82 is rotatably connected with the frame 5. The outside of the rotating shaft 83 is slidably connected with the connecting sleeve 84. The limit pin 85 is slidably connected inside the connecting sleeve 84. The limit pin 85 is threadedly connected with the rotating shaft 83. The connecting sleeve 84 is welded with the gear 86. The gear 86 is meshed with the toothed ring 81. The cylinder 87 is fixedly installed on the frame 5. The cylinder rod 88 of the cylinder 87 is slidably connected with the frame 5. The cylinder rod 88 is welded with the guide seat 89. The outside of the sliding pipe 7 is fixedly sleeved with the support ring 810. The support ring 810 is slidably connected with the guide seat 89. By driving the gear 86 to rotate by the motor 82, the gear 86 drives the toothed ring 81 to rotate, then the liquid inlet pipe 6 rotates, then the spray head 10 rotates, and by driving the cylinder rod 88 to stretch and change by the cylinder 87, the spray head 10 can move up and down inside the tank body 3, so that the spraying inside the tank body 3 is more uniform.

[0032] Among them, the guide seat 89 is welded with the convex block 811, and the convex block 811 contacts the support ring 810. By arranging the convex block 811, the friction between the support ring 810 and the guide seat 89 is reduced.

[0033] Among them, the protection mechanism 9 includes a gland 91, a retaining ring 92, a ring groove 93, a slider 94, a compression spring 95, and a bellows 96. The gland 91 is movably connected to the outer side of the sliding tube 7, and the gland 91 contacts the tank body 3. The retaining ring 92 is slidably connected to the outer side of the sliding tube 7. The ring groove 93 is formed in the sliding tube 7. The slider 94 is welded to the retaining ring 92, and the slider 94 is slidably connected in the ring groove 93. The compression spring 95 is arranged on the outer side of the sliding tube 7. One end of the compression spring 95 is welded to the retaining ring 92, and the other end of the compression spring 95 is welded to the gland 91. By moving the sliding tube 7 into the tank body 3, the retaining ring 92 acts on the compression spring 95, so that the compression spring 95 presses the gland 91 against the tank body 3 to seal the tank body 3, avoiding the atomized paint from drifting out during the spraying process and reducing the environmental pollution during the use of the device.

[0034] Among them, the bellows 96 is adhered to the retaining ring 92, and the bellows 96 is adhered to the gland 91. By arranging the bellows 96, the compression spring 95 is protected.

[0035] The usage state of the present invention is as follows: during use, place the tank body 3 on the cushion ring 4, press down the tank body 3, causing the cushion ring 4 to deform. The tank body 3 comes into contact with the suction cup 22, causing the suction cup 22 to be pressed and deformed. At this time, press down the pressure ring 28, causing the pressure rod 27 to drive the slide rod 25 to move downward, causing the piston 23 to move downward and compress the spring 24, causing the air above the piston 23 to be discharged from the chute 26. Then release the pressure ring 28, and the spring 24 resets to cause the piston 23 to reset, creating a negative pressure at the upper end of the piston. As a result, the suction cup 22 adsorbs the tank body 3. By bringing the tank body 3 into contact with the suction cup 22 and pressing down the suction cup 22, and by moving the piston 23 to discharge the air in the cylinder body 21, the cylinder body 21 is adsorbed by the suction cup 22, making it convenient to fix the tank body 3 in the device. Then start the motor 82. When the motor 82 starts, the rotating shaft 83 rotates. The rotating shaft 83 drives the gear 86 to rotate, and the gear 86 drives the toothed ring 81 to rotate, thereby causing the liquid inlet pipe 6 to rotate. The liquid inlet pipe 6 drives the sliding pipe 7 to rotate. At the same time, start the cylinder 87. When the cylinder 87 starts, the cylinder rod 88 extends. The extension of the cylinder rod 88 drives the guide seat 89 to move, and the guide seat 89 drives the support ring 810 to move, causing the sliding pipe 7 to slide on the outside of the liquid inlet pipe 6, thereby causing the spray head 10 to move into the tank body 3. During this process, the pressure cover 91 comes into contact with the tank body 3. As the sliding pipe 7 continues to move downward, the retaining ring 92 acts on the compression spring 95, causing the compression spring 95 to elastically press the pressure cover 91 against the tank body 3 to seal the tank body 3. By moving the sliding pipe 7 into the tank body 3, the retaining ring 92 acts on the compression spring 95, causing the compression spring 95 to press the pressure cover 91 against the tank body 3 to seal the tank body 3, preventing the atomized paint from drifting out during the spraying process and reducing the environmental pollution during the use of the device. Then introduce paint through the liquid inlet pipe 6. The paint enters the spray head 10 through the sliding pipe 7 to spray the inner wall of the tank body 3. By driving the gear 86 to rotate through the motor 82, the gear 86 drives the toothed ring 81 to rotate, thereby causing the liquid inlet pipe 6 to rotate, causing the spray head 10 to rotate, and by driving the telescopic change of the cylinder rod 88 through the cylinder 87, the spray head 10 can move up and down in the tank body 3, making the spraying in the tank body 3 more uniform.
