Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe processing, in particular to an anti-corrosion coating applicator for stainless steel pipes. Background Art

[0002] In the production of stainless steel pipes, in order to ensure the service life of the pipes, an anti-corrosion coating needs to be applied to the surface of the pipes. When the traditional applicator works, it can only complete the coating work on the surface of the pipes. That is to say, the traditional applicator only has the function of spraying the coating on the surface of the pipes, and it is difficult to spray the coating onto the inner surface of the pipes. Therefore, after spraying the coating on the surface of the pipes, it is often necessary to remove the pipes from the applicator and use another method to spray the inner surface of the pipes, such as manually spraying the inner surface of the pipes with a spray gun. This undoubtedly increases the working intensity of the user, and the working steps are also relatively cumbersome, time-consuming, and inefficient.

[0003] In view of the above problems, the utility model is improved. Summary of the Invention

At the top of one end inside the bracket, a support device is provided. The support device includes a fixed block fixedly installed on the bracket. One end of the fixed block is fixedly installed with an inner pipe. An inner spray head is penetrated through the inner wall of the inner pipe. One end of the inner spray head penetrates to the outside of the bracket. The surface of the fixed block is provided with uniformly distributed sliding grooves. A slider is slidably installed inside the sliding grooves. One end of the slider is fixedly connected with a support plate located outside the fixed block. One end of the slider located inside the inner cavity of the sliding groove is fixedly connected with a spring. The end of the spring far from the slider is fixedly connected to the inner wall of the fixed block. An outer steel pipe workpiece is arranged outside the inner pipe. The end of the support plate extends into the inside of the steel pipe workpiece.

[0006] For the anti-corrosion coating applicator for stainless steel pipes as described above in the utility model, further: Two mounting frames are fixedly installed inside the bracket. Two relatively arranged outer spray plates are rotatably installed between the two mounting frames. Uniformly distributed outer spray heads are penetrated through the surface of the outer spray plates.

[0007] For the anti-corrosion coating applicator for stainless steel pipes as described above in the utility model, further: Pad blocks are fixedly installed on both sides of the bracket. Electric push rods are movably installed on the tops of the pad blocks. The output ends of the electric push rods are movably installed outside the outer spray plates.

[0008] The anti-corrosion coating applicator for stainless steel pipes of the present utility model as described above further includes: a guide rail is fixedly installed on one side of the bracket, a limiting groove is formed at the top of the guide rail, a limiting block is slidably installed inside the limiting groove, and an adjusting table is fixedly installed at the top of the limiting block.

[0009] The anti-corrosion coating applicator for stainless steel pipes of the present utility model as described above further includes: a positioning pin penetrates through the top of the adjusting table, a plurality of jacks I adapted to the positioning pin are formed on one side of the top of the adjusting table, and a plurality of jacks II adapted to the positioning pin are formed on one side of the top of the guide rail.

[0010] The anti-corrosion coating applicator for stainless steel pipes of the present utility model as described above further includes: rollers are fixedly installed on both sides of the bottom of the adjusting table, and the rollers roll closely on the surface of the guide rail.

[0012] In summary, the beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model adopts a structural design that can simultaneously apply anti-corrosion liquid to the inner and outer surfaces of steel pipes of different sizes. Only one working process is required to complete the application work on the inner and outer surfaces of the steel pipes, shortening the time of the steel pipe application work, improving the efficiency of the anti-corrosion coating application work of the steel pipes, ensuring the uniformity of the coating application on the steel pipe surface, and at the same time being able to meet the working requirements of steel pipes of different sizes, providing convenience for the user's work.

[0014] 2. Through the setting of the outer spray plate, outer spray head, cushion block and electric push rod, when applying the coating to the steel pipe workpiece, the electric push rod is started to work. The electric push rod will push the outer spray plate to flip towards the steel pipe workpiece. Finally, the two outer spray plates are combined together to "wrap" the steel pipe workpiece. Then, the coating material will be sprayed on the surface of the steel pipe workpiece through the outer spray head. At this time, the steel pipe workpiece is also rotating, so as to ensure that the coating material is evenly applied on the steel pipe workpiece and improve the quality of the coating application work of the steel pipe workpiece.

[0015] 3. Through the settings of the guide rail, adjustment table, limit block and limit groove, when the adjustment table moves, it will drive the limit block to slide in the limit groove. In this way, the limit groove can limit the movement of the limit block, and at the same time, it can also limit the movement of the adjustment table and the stepping motor, improving the stability of the adjustment table and the stepping motor during movement and providing convenience for the user's work.

[0016] 4. Through the settings of the first jack, the second jack and the positioning pin, the first jack and the second jack are respectively opened on the adjustment table and the guide rail.

[0017] 5. Through the setting of the roller, when adjusting the position of the stepping motor, the adjustment table will move on the guide rail, and at the same time, the roller will also roll accordingly. In this way, it can not only provide support for the movement of the adjustment table, but also improve the smoothness of the adjustment table during movement, providing assistance for the user's adjustment work.

[0018] 6. Through the settings of the stepping motor and the clamping mechanism, the steel pipe workpiece extends into the frame and is fixed by two adjusting screws and clamping blocks. The stepping motor is used to drive the clamping mechanism to rotate, so that the steel pipe workpiece can be driven to rotate, ensuring the normal progress of the coating work of the steel pipe workpiece. When in use, rotate the adjusting screw. Since the adjusting screw is installed on the frame by means of a threaded connection, when the adjusting screw is rotated, it will drive the adjusting screw to move towards the inside of the frame, and at the same time, the adjusting screw will also drive the clamping block to move. In this way, the two clamping blocks move towards each other to clamp and fix the steel pipe workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

Embodiment

[0027] A stainless steel pipe anti-corrosion coating applicator, including a bracket 1. At the top of one end inside the bracket 1, a support device 7 is provided. The support device 7 includes a fixed block 71 fixedly installed on the bracket 1. One end of the fixed block 71 is fixedly installed with a built-in pipe 16. An inner spray head 17 is penetrated through the inner wall of the built-in pipe 16. One end of the inner spray head 17 penetrates to the outside of the bracket 1. Uniformly distributed chutes 72 are formed on the surface of the fixed block 71. A slide block 73 is slidably installed inside the chute 72. One end of the slide block 73 is fixedly connected to a support plate 75 located outside the fixed block 71. One end of the slide block 73 located inside the inner cavity of the chute 72 is fixedly connected to a spring 74. The end of the spring 74 away from the slide block 73 is fixedly connected to the inner wall of the fixed block 71. A steel pipe workpiece 15 is arranged outside the built-in pipe 16. The end of the support plate 75 extends into the inside of the steel pipe workpiece 15.

[0028] The specific usage process is as follows: During operation, first start the electric push rod 6 to work. The electric push rod 6 pulls the outer spraying plate 3 outward to expand it. Then, adjust the position of the stepping motor 9. Therefore, the user needs to first pull out the positioning pin 12, and then push the stepping motor 9 outward. At the same time, the clamping mechanism 8 will also move outward accordingly. When the stepping motor 9 moves, the adjustment table 11 will also move along the guide rail 10. At the same time, the roller 18 will roll closely on the surface of the guide rail 10. In this way, it can not only provide support for the movement of the adjustment table 11, but also improve the smoothness of the movement of the adjustment table 11, providing assistance for the user's adjustment work. Among them, when the adjustment table 11 adjusts and moves, it will drive the limit block 13 to slide in the limit slot 14. In this way, the limit slot 14 can play a role in limiting the movement of the limit block 13, and at the same time, it can also play a role in limiting the movement of the adjustment table 11 and the stepping motor 9, improving the stability of the movement of the adjustment table 11 and the stepping motor 9, providing convenience for the user's work. Then, insert one end of the steel pipe workpiece 15 into the interior of the frame 81. Since the steel pipe workpiece 15 is inserted into the frame 81 and is fixed by two adjustment screws 82 and clamping blocks 83, and the stepping motor 9 is used to drive the clamping mechanism 8 to rotate, it can drive the steel pipe workpiece 15 to rotate, ensuring the normal progress of the coating work of the steel pipe workpiece 15. When in use, rotate the adjustment screw 82. Since the adjustment screw 82 is installed on the frame 81 by means of a threaded connection, when rotating the adjustment screw 82, it will drive the adjustment screw 82 to move into the interior of the frame 81. At the same time, the adjustment screw 82 will also drive the clamping block 83 to move. In this way, the two clamping blocks 83 move towards each other to clamp and fix the steel pipe workpiece 15. It should be noted that before fixing the steel pipe workpiece 15, the steel pipe workpiece 15 should first be sleeved on the inner pipe 16 and adjusted by moving the inner pipe 16, and finally fixed on the clamping mechanism 8. Then, move the stepping motor 9 back until the other end of the steel pipe workpiece 15 is sleeved on the support device 7. In the initial state, the support device 7 is in an expanded state. As the steel pipe workpiece 15 moves, multiple support plates 75 inside the steel pipe workpiece 15 will be squeezed and contract towards the center point of the fixed block 71. At the same time, the support plate 75 will drive the slider 73 to slide in the chute 72, and at the same time, the chute 72 will compress the spring 74 until the support plate 75 completely contracts and stops moving. At this time, the steel pipe workpiece 15 is also difficult to move further. Then, insert the positioning pin 12 back into the corresponding jack one and jack two, and the adjustment table 11 can be positioned at the current position, thus ensuring the stability of the adjustment table 11 and the stepping motor 9 after adjustment, providing convenience for the user's work. Then start the stepping motor 9 to work. The stepping motor 9 drives the clamping mechanism 8 to rotate, and the clamping mechanism 8 will drive the steel pipe workpiece 15 to rotate. At the same time, the steel pipe workpiece 15 will also rotate on the multiple support plates 75, but the support plates 75 will not rotate accordingly. It should be noted that some balls can also be arranged on the surface of the support plates 75 to provide assistance for the rotation of the steel pipe workpiece 15 and reduce friction.At the same time, it can also reduce wear and ensure the normal progress of the coating work of the steel pipe workpiece 15, providing convenience for the user's work. Then, control the electric push rod 6 to push the outer spray plate 3 to turn towards the steel pipe workpiece 15. Finally, the two outer spray plates 3 are combined together to "wrap" the steel pipe workpiece 15. Then, the coating material will be sprayed on the surface of the steel pipe workpiece 15 through the outer spray head 4. At this time, the steel pipe workpiece 15 is also rotating, so as to ensure that the coating material is evenly coated on the steel pipe workpiece 15 and improve the quality of the coating work of the steel pipe workpiece 15. It should be noted that the outer spray head 4 on the outer spray plate 3 and the inner spray head 17 on the inner pipe 16 will spray simultaneously, so as to complete the anti-corrosion coating spraying work on the inner and outer surfaces of the steel pipe workpiece 15 and improve the work efficiency of the user.

[0029] Therefore, by adopting a structural design that can simultaneously coat the inner and outer surfaces of steel pipes of different sizes with anti-corrosion liquid, the coating work on the inner and outer surfaces of the steel pipe can be completed in only one working process, shortening the time of the steel pipe coating work, improving the efficiency of the anti-corrosion coating work of the steel pipe, ensuring the uniformity of the coating on the steel pipe surface, and at the same time being able to meet the working requirements of steel pipes of different sizes, providing convenience for the user's work.

[0030] Two mounting brackets 2 are fixedly installed on the inner side of the bracket 1. Two relatively arranged outer spray plates 3 are rotatably installed between the two mounting brackets 2. The surface of the outer spray plate 3 is provided with evenly distributed outer spray heads 4 in a penetrating manner. Fixed blocks 5 are fixedly installed on both sides of the bracket 1. An electric push rod 6 is movably installed on the top of the fixed block 5. The output end of the electric push rod 6 is movably installed on the outer side of the outer spray plate 3.

[0031] Specifically, the settings of the outer spray plate 3, the outer spray head 4, the fixed block 5 and the electric push rod 6 are as follows. When coating the steel pipe workpiece 15, start the electric push rod 6 to work. The electric push rod 6 will push the outer spray plate 3 to turn towards the steel pipe workpiece 15. Finally, the two outer spray plates 3 are combined together to "wrap" the steel pipe workpiece 15. Then, the coating material will be sprayed on the surface of the steel pipe workpiece 15 through the outer spray head 4. At this time, the steel pipe workpiece 15 is also rotating, so as to ensure that the coating material is evenly coated on the steel pipe workpiece 15 and improve the quality of the coating work of the steel pipe workpiece 15.

[0032] A guide rail 10 is fixedly installed on one side of the bracket 1. A limit groove 14 is opened at the top of the guide rail 10. A limit block 13 is slidably installed inside the limit groove 14. An adjustment table 11 is fixedly installed on the top of the limit block 13.

[0033] Specifically, the settings of the guide rail 10, the adjustment table 11, the limit block 13 and the limit groove 14 cause the limit block 13 to slide within the limit groove 14 when the adjustment table 11 is adjusted and moved. In this way, the limit groove 14 can limit the movement of the limit block 13 and also limit the movement of the adjustment table 11 and the stepping motor 9, improving the stability of the adjustment table 11 and the stepping motor 9 during movement and providing convenience for the user's work.

[0034] A positioning pin 12 is provided through the top of the adjustment table 11. On one side of the top of the adjustment table 11, a plurality of first jacks adapted to the positioning pin 12 are provided. On one side of the top of the guide rail 10, a plurality of second jacks adapted to the positioning pin 12 are provided.

[0035] Specifically, due to the settings of the first jacks, the second jacks and the positioning pin 12, with the first jacks and the second jacks being respectively provided on the adjustment table 11 and the guide rail 10, after the adjustment work is completed, the user can insert the positioning pin 12 into the corresponding first jacks and second jacks to position the adjustment table 11 at the current position, thus ensuring the stability of the adjustment table 11 and the stepping motor 9 after adjustment and providing convenience for the user's work.

[0036] On both sides of the bottom of the adjustment table 11, rollers 18 are fixedly installed, and the rollers 18 roll closely on the surface of the guide rail 10.

[0037] Specifically, due to the setting of the rollers 18, when adjusting the position of the stepping motor 9, the adjustment table 11 will move on the guide rail 10, and at the same time, the rollers 18 will also roll accordingly. In this way, it can not only provide support for the movement of the adjustment table 11 but also improve the smoothness of the adjustment table 11 during movement, providing assistance for the user's adjustment work.

[0038] A stepping motor 9 is fixedly installed on the top of the adjustment table 11. A clamping mechanism 8 is fixedly installed on the output shaft of the stepping motor 9. The clamping mechanism 8 includes a frame 81 fixedly installed on the stepping motor 9. One end of the steel pipe workpiece 15 extends into the inner side of the frame 81. Adjusting screws 82 are provided through the top and bottom of the frame 81, and a clamping block 83 adapted to the steel pipe workpiece 15 is fixedly connected to the end of the adjusting screw 82 located inside the frame 81.

[0039] Specifically, with the stepper motor 9 and the clamping mechanism 8 provided, the steel pipe workpiece 15 extends into the frame 81 and is fixed by two adjusting screws 82 and clamping blocks 83. The stepper motor 9 is used to drive the clamping mechanism 8 to rotate, so as to drive the steel pipe workpiece 15 to rotate, ensuring the normal progress of the coating work of the steel pipe workpiece 15. When in use, rotate the adjusting screw 82. Since the adjusting screw 82 is installed on the frame 81 in a threaded connection manner, rotating the adjusting screw 82 will drive the adjusting screw 82 to move towards the inside of the frame 81. At the same time, the adjusting screw 82 will also drive the clamping block 83 to move. In this way, the two clamping blocks 83 moving towards each other can clamp and fix the steel pipe workpiece 15.
