Description

Technical Field

[0001] The invention relates to the field of spraying equipment, and more specifically to a surface spraying equipment for a stainless steel grooved pipe. Background Art

[0002] Stainless steel grooved pipe is a kind of pipe made of stainless steel material, which is widely used in chemical, petroleum, food processing, pharmaceutical and other industries. This type of pipe is designed to transport various fluids, including water, gas and chemicals, etc., and due to its material characteristics, it has excellent corrosion resistance, durability and long service life.

[0003] In order to enhance the corrosion resistance of stainless steel grooved pipes, improve their appearance or add specific functionality, the surface of stainless steel grooved pipes is usually sprayed with paint. The spraying work is usually carried out on the stainless steel grooved pipes after all machining and forming processes are completed to ensure that the coating is not damaged during the processing.

[0004] During the spraying process of stainless steel grooved pipes, due to the influence of environmental factors, the processing workshop is prone to be in a humid state. In a high humidity environment, the moisture content in the air increases, which will cause the solvent in the coating to be difficult to evaporate quickly. This not only makes the fluidity of the coating on the surface of the stainless steel grooved pipe worse, but also easily forms bubbles and pinholes. This situation not only weakens the protective performance of the coating, but also significantly reduces its appearance quality. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) In this scheme, when the hot air blower blows hot air to the stainless steel grooved pipe body, the fan blade 1 and the cross plate cooperate to achieve uniform preheating of the stainless steel grooved pipe body. After the paint is sprayed on the surface of the stainless steel grooved pipe body, the paint can maintain a low viscosity, flow and flatten better, help reduce or eliminate bubbles and pinholes in the coating, improve the smoothness of the coating, and help speed up the evaporation rate of the solvent and reduce the possibility of solvent residue in the coating, thereby improving the protective performance of the coating.

[0021] (2) In the spraying process, the ball reciprocates to hit the inner wall of the circular cavity and vibrates the circular plate. The shock wave is transmitted to the stainless steel grooved tube body and causes the surface of the stainless steel grooved tube body to vibrate slightly. The slight vibration can make the coating more evenly distributed on the entire surface, especially for workpieces with complex shapes or concave and convex structures. It helps to fill small gaps and reduce thickness differences. At the same time, it can enhance the contact between the coating molecules and the substrate to a certain extent, which theoretically helps to improve the adhesion of the coating.

[0022] (3) In this scheme, the large gear and the front small gear are matched. The large gear will drive the front small gear to rotate rapidly, and the front small gear will drive the fan blade 2 to rotate synchronously. At this time, the fan blade 2 can blow the surface of the stainless steel grooved tube body after spraying. The appropriate airflow can help the solvent in the paint evaporate from the surface faster, thereby accelerating the drying speed of the coating, which is beneficial to improving production efficiency. At the same time, the continuous airflow can blow dust and other particulate matter in the surrounding environment away from the spraying area, reducing the possibility of these impurities adhering to the wet coating.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 6 , a stainless steel grooved pipe surface spraying equipment, comprising a base 1, a support plate 2 is fixedly installed on the top of the base 1, and also includes:

[0033] A clamping assembly, the clamping assembly includes two groups of circular frames 3 arranged above the base 1, the circular frame 3 close to the side of the support plate 2 is fixedly installed on the base 1, and the circular frame 3 away from the side of the support plate 2 is slidably installed on the base 1, circular plates 4 are rotatably installed in the two groups of circular frames 3, a stainless steel groove tube body 7 is contacted between the two groups of circular plates 4, a telescopic spring 5 is directly fixedly installed on the top of the circular frame 3 away from the side of the support plate 2 and the base 1, a motor 6 is fixedly installed on one side of the support plate 2, the circular plate 4 close to the side of the support plate 2 is fixedly installed on the output shaft of the motor 6, and a preheating assembly is provided on the side of the support plate 2 away from the motor 6.

[0034] The preheating assembly includes a fixed cylinder 14 fixedly mounted on the support plate 2, the fixed cylinder 14 is rotatably mounted with the adjacent circular plate 4, a hot air blower 15 is arranged below the fixed cylinder 14, the hot air blower 15 is fixedly mounted with the base 1, and the output end of the hot air blower 15 is fixedly mounted with the fixed cylinder 14, and two groups of circular plates 4 are respectively provided with multiple groups of through openings 16, and the inner cavity of each group of the through openings 16 near the side of the fixed cylinder 14 is rotatably mounted with a fan blade 17, and each group of the fan blade 17 is fixedly mounted with a cross plate 18 at one end near the stainless steel grooved pipe body 7;

[0035] A top frame 8 is fixedly mounted on one side of the support plate 2, a threaded rod 9 is rotatably mounted inside the top frame 8, a motor 10 is fixedly mounted on one side of the support plate 2, an output shaft of the motor 10 is fixedly mounted on the threaded rod 9, a T-shaped block 11 is threadedly mounted on the threaded rod 9, the T-shaped block 11 is slidably mounted on the top frame 8, a nozzle 12 is fixedly mounted on the bottom of the T-shaped block 11, and a hose 13 is fixedly mounted on the top of the nozzle 12.

[0036] First, the user connects the hose 13 to the external paint output pipe, and then pulls the left circular plate 4 to move to the left, so that there is a gap between the two groups of circular plates 4 to place the stainless steel grooved pipe body 7. The left circular plate 4 squeezes the telescopic spring 5 while moving to the left. After the gap between the two groups of circular plates 4 is vacated, the stainless steel grooved pipe body 7 is placed between the two groups of circular plates 4, and the right end of the stainless steel grooved pipe body 7 is stuck on the right circular plate 4. Then, the pressure applied to the left circular plate 4 is canceled, and under the action of the telescopic spring 5, the stainless steel grooved pipe body 7 is placed between the two groups of circular plates 4. , the telescopic spring 5 returns to its initial state and pushes the circular plate 4 on the left to move to the right and get stuck at the left end of the stainless steel grooved tube body 7. At this time, the two groups of circular plates 4 can clamp and fix the stainless steel grooved tube body 7. Turn on the motor 16, and the output shaft of the motor 16 will drive the circular plate 4 on the right to rotate. Through the clamping force, the stainless steel grooved tube body 7 and the circular plate 4 on the left can be driven to rotate synchronously. The two groups of circular plates 4 rotate in the circular frames 3 on their outer sides respectively. At the same time, turn on the hot air blower 15, and the output end of the hot air blower 15 will The fixed cylinder 14 is blown with wind adapted to heat the stainless steel grooved pipe body 7. The hot wind in the inner cavity of the fixed cylinder 14 will be discharged into the inner cavity of the stainless steel grooved pipe body 7 through the right groups of through-ports 16. When the hot wind enters the inner cavity of the right groups of through-ports 16, the wind force will drive the fan blade 17 to rotate. The fan blade 17 will drive the cross plate 18 thereon to rotate while the rotation is being carried out. The right circular plate 4 can drive each group of cross plates 18 to rotate in a circle while the cross plate 18 itself will also rotate. The rotation of the cross plate 18 can realize the improvement of the heat dissipation of the stainless steel grooved pipe body 7. The right side opening 16 is changed to discharge the wind path into the stainless steel grooved pipe body 7, and the wind is dispersed, so that the hot wind can be evenly diffused in the inner cavity of the stainless steel grooved pipe body 7, and the stainless steel grooved pipe body 7 is evenly heated, so that the temperature of the entire surface of the stainless steel grooved pipe body 7 is consistent, and the speed of the hot wind is also reduced, which can increase the contact time of the hot wind with the inner cavity wall of the stainless steel grooved pipe body 7, thereby improving the heating efficiency of the stainless steel grooved pipe body 7, and playing the role of preheating the stainless steel grooved pipe body 7;

[0037] After heating the stainless steel grooved pipe body 7, the motor 2 10 is turned on, and the output end of the motor 2 10 will drive the threaded rod 9 to rotate. When the threaded rod 9 rotates, it will drive the T-shaped block 11 to move to the right in the inner cavity of the top frame 8. When the T-shaped block 11 moves, it will drive the nozzle 12 to move synchronously. When the nozzle 12 is turned on, the surface of the stainless steel grooved pipe body 7 can be evenly sprayed. By uniformly preheating the stainless steel grooved pipe body 7, after the paint is sprayed on the surface of the stainless steel grooved pipe body 7, the paint can maintain a low viscosity, flow better and be smoother, which helps to reduce or eliminate bubbles and pinholes in the coating, improve the smoothness of the coating, and at the same time help to accelerate the evaporation rate of the solvent and reduce the possibility of solvent residue in the coating, thereby improving the protective performance of the coating.

[0038] like Figures 3 to 5 As shown, a circular cavity 19 is opened on the side wall of the circular plate 4 near the fixed cylinder 14, and an L-shaped plate 20 is provided in the inner cavity of the circular cavity 19. The L-shaped plate 20 is fixedly installed on the bottom of the inner cavity of the fixed cylinder 14, and a column 21 is slidably installed on the L-shaped plate 20. A return spring 22 is fixedly installed between the column 21 and the L-shaped plate 20, and a ball 23 is rollingly installed on the bottom end of the column 21. Arc plates 24 are evenly fixedly installed on the inner cavity wall of the circular cavity 19, and the bottom of the ball 23 is in contact with the adjacent arc plate 24.

[0039] A circular plate 25 is rotatably mounted on one side of the inner cavity of the circular cavity 19 close to the fixing cylinder 14 , and the circular plate 25 is fixedly mounted to the L-shaped plate 20 .

[0040] In the initial state, the ball 23 is in contact with the top of the lowermost arc-shaped plate 24, and the return spring 22 is in a compressed state. When the motor 6 drives the right circular plate 4 to rotate, the right circular plate 4 will drive the groups of arc-shaped plates 24 in the inner cavity of the circular cavity 19 to move synchronously. When the lowermost arc-shaped plate 24 moves out of the bottom of the ball 23, under the action of the return spring 22, the return spring 22 restores the initial state and pushes the column 21 to move downward. When the column 21 moves downward, it will drive the ball 23 to move downward synchronously, so that the column 21 can drive the ball 23 to hit the inner cavity wall of the circular cavity 19. When the next group of arc-shaped plates 24 moves to the position of the ball 23, the arc of the arc plate 24 The setting of the surface can realize that the arc plate 24 pushes the ball 23 to drive the column 21 to move upward and squeeze the reset spring 22. At this time, during the rotation of the right circular plate 4, the ball 23 can reciprocate and hit the inner wall of the circular cavity 19, and vibrate the circular plate 4. The shock wave will be transmitted to the stainless steel grooved pipe body 7, and the surface of the stainless steel grooved pipe body 7 will vibrate slightly. The slight vibration can make the coating more evenly distributed on the entire surface, especially for workpieces with complex shapes or concave-convex structures, which helps to fill small gaps and reduce thickness differences. At the same time, it can enhance the contact between the coating molecules and the substrate to a certain extent, which theoretically helps to improve the adhesion of the coating.

[0041] The right circular plate 4 will rotate on the annular plate 25 during the rotation process. The setting of the annular plate 25 can realize sealing of the inner cavity of the circular cavity 19, preventing the hot air blown by the hot air blower 15 to the inner cavity of the fixed cylinder 14 from being discharged into the inner cavity of the circular cavity 19, and avoiding the situation where the temperature of the inner cavity parts of the circular cavity 19 increases and the sliding friction increases, thereby effectively improving the sliding effect of the parts, facilitating the impact work, and further effectively improving the service life of the parts.

[0042] like Figure 1 and Figure 2As shown, a baffle 26 is fixedly installed on one side of the T-shaped block 11, and a top plate 27 is fixedly installed on the side of the baffle 26 away from the T-shaped block 11. Two groups of small gears 29 are rotatably installed on the top of the top plate 27, and a large gear 30 is arranged between the two groups of small gears 29. The large gear 30 is rotatably installed with the top plate 27.

[0043] Teeth 31 are evenly installed on the inner wall of the top frame 8, the small gear 29 close to the teeth 31 is meshed with the adjacent teeth 31, and the small gear 29 away from the teeth 31 is meshed with the large gear 30, a belt is installed between the small gear 29 close to the teeth 31 and the large gear 30, and a fan blade 28 is fixedly installed on the bottom end of the small gear 29 away from the teeth 31.

[0044] The small gear 29 at the rear side is in a non-meshing state with the large gear 30, and the small gear 29 at the front side is in a meshing state with the large gear 30. When the output end of the motor 2 10 drives the threaded rod 9 to rotate, the nozzle 12 is driven to move to the right through the T-block 11 and the surface of the stainless steel grooved pipe body 7 is sprayed. When the T-block 11 moves to the right, it drives the baffle 26 and the top plate 27 to move synchronously. When the top plate 27 moves to the right, the small gear 29 at the rear side rotates on the meshing teeth 31 through the setting of each group of teeth 31, and the small gear 29 at the rear side drives the large gear 30 to move synchronously through the belt Rotation, through the cooperation between the large gear 30 and the front small gear 29, the large gear 30 will drive the front small gear 29 to rotate quickly, and the front small gear 29 will drive the fan blade 28 to rotate synchronously. At this time, the fan blade 28 can blow the surface of the stainless steel groove pipe body 7 after spraying appropriately. The appropriate airflow can help the solvent in the paint to evaporate from the surface faster, thereby accelerating the drying speed of the coating, which is beneficial to improving production efficiency. At the same time, the continuous airflow can blow dust and other particulate matter in the surrounding environment away from the spraying area, reducing the possibility of these impurities adhering to the wet coating;

[0045] By setting the baffle 26 , it is possible to block the spraying of the nozzle 12 and the blowing of the second fan blade 28 , thereby playing a blocking role and preventing the blowing of the second fan blade 28 from affecting the spraying work of the nozzle 12 .

[0046] like Figure 4 As shown, one side of each group of the through openings 16 away from the fixed tube 14 is contacted with a sealing block 32, and each group of the sealing blocks 32 is arranged on a side away from the stainless steel grooved tube body 7, and an elastic rope 33 is fixedly installed between each group of the sealing blocks 32 and the inner cavity of the adjacent through openings 16.

[0047] The sum of the elastic forces of the elastic ropes 33 of each group is smaller than the elastic force of the telescopic spring 5 .

[0048] The output end of the hot air blower 15 is used to blow the fixed tube 14 to heat the stainless steel grooved tube body 7. The hot air will be discharged into the inner cavity of the fixed tube 14 through the right groups of through ports 16. The initial state of each group of elastic ropes 33 is in a stretched state. The elastic ropes 33 will pull the sealing block 32 to pre-seal the through ports 16 on the left. When the hot air starts to enter the stainless steel grooved tube body 7, the gas in the stainless steel grooved tube body 7 cannot be discharged. When the pressure in the stainless steel grooved tube body 7 increases, the pressure will push the sealing block 32 on the left side away from the left end of the left through port 16 and stretch the elastic rope 33. When the sealing block 32 is away from the left through port 16, the gas in the stainless steel grooved tube body 7 will be discharged through the left through port 16. The pre-sealing effect of the sealing block 32 can effectively collect heat and improve the heating efficiency of the stainless steel grooved tube body 7.

[0049] like Figure 1 and Figure 2 As shown, the two groups of circular plates 4 are provided with anti-slip patterns on one side close to the stainless steel grooved pipe body 7 .

[0050] The speed ratio between the large gear 30 and the meshing small gear 29 is 1:5.

[0051] By setting the anti-slip texture, the friction force of the contact between the two groups of circular plates 4 and the stainless steel grooved tube body 7 can be increased, so that the right circular plate 4 can drive the stainless steel grooved tube body 7 and the left circular plate 4 to rotate synchronously while rotating, which can improve the stability during rotation. By setting the speed ratio of the large gear 30 to the front small gear 29 to 1:5, the large gear 30 can drive the front small gear 29 to rotate 5 circles when it rotates 1 circle, so as to drive the fan blade 28 to rotate quickly and blow an appropriate amount of wind during the spraying movement.

[0052] Working principle: first connect the hose 13 to the external paint spraying pipe, then pull the left circular plate 4 to clamp and fix the stainless steel grooved pipe body 7 with the cooperation of the telescopic spring 5, then turn on the motor 1 6 to drive the right circular plate 4 to rotate, and make the stainless steel grooved pipe body 7 rotate, and at the same time turn on the hot air blower 15 to blow air into the stainless steel grooved pipe body 7 for preheating. When the hot air is blown into the stainless steel grooved pipe body 7 through the right groups of ports 16, the hot air can be evenly dispersed in the inner cavity of the stainless steel grooved pipe body 7 through the cooperation of the fan blade 17 and the cross plate 18. After the stainless steel grooved pipe body 7 is preheated, turn on the motor 2 10 to drive the nozzle 12 to move to the right to heat the stainless steel grooved pipe. The surface of the main body 7 is sprayed. During the movement of the nozzle 12 for spraying, the fan blade 28 will blow an appropriate amount of air to the surface of the stainless steel grooved tube main body 7 after the paint is sprayed, so as to achieve blowing while spraying. While the right circular plate 4 rotates, the column 21 will drive the ball 23 to reciprocate and impact the inner cavity of the circular cavity 19, and cause the stainless steel grooved tube main body 7 to vibrate slightly. After the spraying is completed, the motor 2 10 is controlled to make the threaded rod 9 drive the nozzle 12 to move to the left and reset, so as to spray the next stainless steel grooved tube main body 7. Stop spraying during the resetting process, and after pulling the left circular plate 4 and the right circular plate 4 to leave a gap, the stainless steel grooved tube main body 7 after spraying can be easily disassembled.

[0053] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
