Description

Technical Field

[0001] This utility model relates to the field of pipe coating technology, specifically to a surface coating device for steel pipe production. Background Technology

[0002] Steel pipes are used for transporting fluids and powdery solids, exchanging heat energy, manufacturing mechanical parts and containers, and are also an economical steel material. Currently, to prevent the surface of metal steel pipes from rusting, a layer of anti-rust paint is usually applied to the surface of the metal steel pipes.

[0003] For example, according to the authorization announcement number CN202222101343.X, this utility model relates to the field of pipe painting and discloses a steel pipe surface spraying device, including a base. Support plates are fixedly connected to the left and right sides of the top of the base. A second rotating shaft is rotatably connected to the middle of the adjacent side of each support plate. A rotating plate is fixedly connected to the side of each second rotating shaft away from the support plate. A support column is fixedly connected to the bottom of the inner wall of each rotating plate. A concave clamping block is fixedly connected to the top of each support column. A lead screw is threaded to the top of each rotating plate. A convex clamping block is fixedly connected to the bottom end of each lead screw. A handle is fixedly connected to the top of the outer wall of each lead screw. The end of each second rotating shaft away from the rotating plate penetrates the adjacent side of the support plate and the rotating plate. In this utility model, the uniform spraying of the steel pipe is achieved by combining the clamping action inside the rotating plate with the rotation driven by a first motor. Simultaneously, a hot air blower dries the steel pipe during the process, ensuring the spraying effect and improving efficiency.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of applying a layer of paint to the surface of metal steel pipes by manual brushing, which is time-consuming and labor-intensive, and where existing mechanical painting devices often have limited functionality, only able to spray paint a single type of steel pipe without being able to rotate the pipe, resulting in poor paint uniformity and the inability to dry the steel pipe in time after painting, thus greatly affecting the painting efficiency, compromising the painting effect, and causing great inconvenience to users, the painting device can only spray most of the steel pipe surface. However, the areas on both sides of the steel pipe that are clamped cannot be sprayed by the painting machine, requiring the user to manually rotate the steel pipe or manually brush the paint onto the areas that are not to be sprayed, thus limiting the painting equipment's capabilities. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a surface spraying device for steel pipe production, which has the advantage of comprehensive spraying. It solves the problem that while the spraying device can spray most of the steel pipe surface, the spraying machine cannot spray the areas on both sides of the steel pipe surface that are clamped, requiring the user to manually rotate the angle of the steel pipe or manually brush the areas to be sprayed, thus limiting the spraying equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surface spraying device for steel pipe production, comprising a base plate, a support column, a first moving roller, a sprayer, a second moving roller, a fan, and a first motor. The top two sides of the base plate are fixedly connected to the bottom of the support column. The two sides of the first moving roller are movably connected to the front inner side of the support column via pins. The surface of the first moving roller is threadedly connected to the inner wall of the sprayer. The two sides of the first moving roller are movably connected to the top inner side of the support column via pins. The inner wall of the fan is threadedly connected to the surface of the second moving roller. The right side of the second moving roller... A first motor is fixedly connected to the output end of the first motor through the outer side of the support column. A rotating groove is opened on the inner side of the support column. A rotating rod is slidably connected to the inner wall of the rotating groove. A second motor is fixedly connected to the outer side of the rotating rod away from the first motor. A fixed rod is fixedly connected to the inner side of the rotating rod. A double-acting screw is movably connected to the top and bottom of the inner wall of the fixed rod through a shaft pin. Moving plates are threaded to both sides of the surface of the double-acting screw. A support rod is fixedly connected to the inner side of the moving plate. A transmission assembly is fixedly connected to the top of the fixed rod. An auxiliary assembly is opened on the inner side of the support column.

[0007] In a preferred embodiment of this invention, the transmission assembly includes a third motor, the output end of which extends through to the top of the inner wall of the fixed rod and is fixedly connected to the top of the bidirectional lead screw. A control panel is fixedly connected to the left side of the front of the support column, and the control panel is electrically connected to the third motor via a wire.

[0008] As a preferred embodiment of this utility model, the auxiliary component includes a movable groove, which is opened on the inner side of the support column. A movable rod is slidably connected to the inner wall of the movable groove, and the inner side of the movable rod is fixedly connected to both sides of the outer side of the fixed rod.

[0009] As a preferred embodiment of this utility model, auxiliary rods are fixedly connected to both the top and bottom outer sides of the inner wall of the fixed rod, and the surface of the fixed rod is slidably connected to the inner wall of the movable plate.

[0010] As a preferred embodiment of this utility model, a fixing strip is fixedly connected to the left side of the front of the support column, an installation groove is provided on the front of the fixing strip, an installation strip is slidably connected to the inner wall of the installation groove, and a protective plate is fixedly connected to the front of the installation strip.

[0011] As a preferred embodiment of this invention, both sides of the surface of the movable rod are fixedly connected to blocking blocks, and a spring is movably sleeved on the surface of the movable rod.

[0012] As a preferred embodiment of this utility model, a shielding plate is fixedly connected to the left side of the fixing strip, and auxiliary plates are fixedly connected to the top and bottom of the protective plate. Several auxiliary plates are provided and are distributed at equal intervals.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a bidirectional lead screw, a moving plate, and a fixed rod, first aligns the notch of the steel pipe with the fixed rod, moves the fixed rod to the inside of the steel pipe, and then rotates the bidirectional lead screw. The moving plate moves up and down due to the rotation of the bidirectional lead screw while the moving plate remains stationary. Since the moving plate is fixedly connected to the fixed rod, the fixed rod can be fixed according to the diameter of the steel pipe, allowing the entire surface of the steel pipe to be sprayed. This solves the problem that while the spraying device can spray most of the steel pipe surface, the areas clamped on both sides of the steel pipe cannot be sprayed, requiring the user to manually rotate the angle of the steel pipe or manually apply paint to the unsprayed areas, thus limiting the spraying equipment's capabilities. This invention achieves a comprehensive spraying effect.

[0015] 2. This utility model, by setting up a transmission component, allows the user to place the steel pipe on the fixed rod. The control panel transmits an opening electrical signal to the third motor. After receiving the electrical signal from the control panel, the third motor will start to rotate. The rotation of the output end of the third motor drives the bidirectional lead screw to rotate, thereby moving the moving plate up and down. This allows the steel pipe to be quickly fixed between the support columns, thus achieving the effect of assisting in fixing the steel pipe.

[0016] 3. By setting up auxiliary components, when the user needs to place the steel pipe on the fixed rod, the fixed rod on either side of the steel pipe can be moved towards the support column. The movable rod can be moved into the interior of the support column, increasing the distance between the fixed rods. This allows the user to align the steel pipe with the support rod first. After the steel pipe is placed horizontally, the other end of the steel pipe can be aligned with another support rod, making it easier for the user to place the steel pipe. The movable groove can restrict the movement direction of the movable rod. At the same time, when the fixed rod rotates, it drives the movable rod to rotate, allowing the movable rod to move inside the movable groove, making its movement more stable, thus achieving the effect of assisting in the placement of the steel pipe.

[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4As shown, this utility model provides a surface coating device for steel pipe production, including a base plate 1, a support column 2, a first moving roller 3, a sprayer 4, a second moving roller 5, a fan 6, and a first motor 7. The top two sides of the base plate 1 are fixedly connected to the bottom of the support column 2. The two sides of the first moving roller 3 are movably connected to the front side of the inner side of the support column 2 through axle pins. The surface of the first moving roller 3 is threadedly connected to the inner wall of the sprayer 4. The two sides of the first moving roller 3 are movably connected to the top of the inner side of the support column 2 through axle pins. The inner wall of the fan 6 is threadedly connected to the surface of the second moving roller 5. The right side of the second moving roller 5 extends through to the outer side of the support column 2. The support column 2 is fixedly connected to the output end of the first motor 7. A rotating groove 8 is provided on the inner side of the support column 2. A rotating rod 9 is slidably connected to the inner wall of the rotating groove 8. The end of the rotating rod 9 away from the first motor 7 passes through to the outer side of the support column 2 and is fixedly connected to the second motor 10. A fixing rod 11 is fixedly connected to the inner side of the rotating rod 9. A double-acting screw 12 is movably connected to the top and bottom of the inner wall of the fixing rod 11 through a shaft pin. A moving plate 13 is threaded to both sides of the surface of the double-acting screw 12. A support rod 14 is fixedly connected to the inner side of the moving plate 13. A transmission assembly 15 is fixedly connected to the top of the fixing rod 11. An auxiliary assembly 16 is provided on the inner side of the support column 2.

[0024] refer to Figure 2 The transmission assembly 15 includes a third motor 151. The output end of the third motor 151 extends through to the top of the inner wall of the fixed rod 11 and is fixedly connected to the top of the bidirectional lead screw 12. A control panel 152 is fixedly connected to the left side of the front of the support column 2. The control panel 152 is electrically connected to the third motor 151 through wires.

[0025] As a technical optimization of this utility model, by setting up a transmission component 15, when the user places the steel pipe on the fixed rod 11, the control panel 152 transmits an opening electrical signal to the third motor 151. After receiving the electrical signal from the control panel 152, the third motor 151 will start to rotate. The rotation of the output end of the third motor 151 drives the bidirectional lead screw 12 to rotate, thereby allowing the moving plate 13 to move up and down, thus quickly fixing the steel pipe between the support columns 2, thereby achieving the effect of assisting in fixing the steel pipe.

[0026] refer to Figure 2 The auxiliary component 16 includes a movable groove 161, which is opened on the inner side of the support column 2. The inner wall of the movable groove 161 is slidably connected to a movable rod 162, and the inner side of the movable rod 162 is fixedly connected to the two sides of the outer side of the fixed rod 11.

[0027] As a technical optimization of this utility model, by setting the auxiliary component 16, when the user needs to place the steel pipe on the fixed rod 11, the fixed rod 11 on either side of the steel pipe can be moved towards the support column 2, and the movable rod 162 can be moved into the support column 2, so that the distance between the fixed rods 11 is increased. This allows the user to first align the steel pipe with the support rod 14. After the steel pipe is placed horizontally, the other end of the steel pipe is aligned with another support rod 14, which makes it easier for the user to place the steel pipe. The movable groove 161 can restrict the movement direction of the movable rod 162. At the same time, when the fixed rod 11 rotates and drives the movable rod 162 to rotate, the movable rod 162 can move inside the movable groove 161, making its movement more stable, thereby achieving the effect of assisting in the placement of the steel pipe.

[0028] refer to Figure 3 Auxiliary rods 17 are fixedly connected to both the top and bottom outer sides of the inner wall of the fixed rod 11, and the surface of the fixed rod 11 is slidably connected to the inner wall of the movable plate 13.

[0029] As a technical optimization of this utility model, by setting an auxiliary rod 17, when the bidirectional lead screw 12 rotates, the auxiliary rod 17 can restrict the movement direction of the moving plate 13, so that the moving plate 13 will not rotate with the bidirectional lead screw 12, thus avoiding the situation where the bidirectional lead screw 12 rotates and the moving plate 13 follows it, thereby achieving the effect of restricting the movement direction of the moving plate 13.

[0030] refer to Figure 4 A fixing strip 18 is fixedly connected to the left side of the front of the support column 2. An installation groove 19 is opened on the front of the fixing strip 18. An installation strip 20 is slidably connected to the inner wall of the installation groove 19. A protective plate 21 is fixedly connected to the front of the installation strip 20.

[0031] As a technical optimization of this utility model, by setting a fixing strip 18, a mounting groove 19, a mounting strip 20, and a protective plate 21, when the control panel 152 is used outdoors, the protective plate 21 is taken out, the left side of the mounting strip 20 on the back of the protective plate 21 is aligned with the mounting groove 19 on the right side of the fixing strip 18, and then the protective plate 21 is moved to the left side of the support column 2, so that the mounting strip 20 is completely moved into the interior of the mounting groove 19. The mounting groove 19 can restrict the movement direction of the mounting strip 20, so that the protective plate 21 covers the front of the control panel 152. The protective plate 21 can prevent the control panel 152 from being hit by external objects, thereby achieving the effect of protecting the control panel 152.

[0032] refer to Figure 3 Both sides of the surface of the movable rod 162 are fixedly connected to the blocking block 22, and the surface of the movable rod 162 is movably sleeved with a spring 23.

[0033] As a technical optimization of this utility model, by setting a blocking block 22 and a spring 23, the blocking block 22 can prevent the moving rod 162 from detaching from the support column 2, thus preventing it from leaving the support column 2. At the same time, the blocking block 22 can also help the moving rod 162 compress the spring 23. When the user installs the steel pipe, the moving fixed rod 11 is moved, causing the spring 23 to be compressed and contracted. When the user no longer applies force to the fixed rod 11, the rebound force of the spring 23 can push the fixed rod 11 back to its original position. At the same time, it can also strengthen the installation of the steel pipe to a certain extent, thereby achieving the effect of assisting the use of the fixed rod 11.

[0034] refer to Figure 2 and Figure 4 A baffle plate 24 is fixedly connected to the left side of the fixing strip 18, and auxiliary plates 25 are fixedly connected to the top and bottom of the protective plate 21. Several auxiliary plates 25 are provided and are distributed at equal intervals.

[0035] As a technical optimization of this utility model, by setting up a baffle plate 24 and an auxiliary plate 25, when the mounting strip 20 is completely moved into the mounting groove 19, the baffle plate 24 can prevent the mounting strip 20 from continuing to move to the left side of the fixing strip 18, so that it stays inside the mounting groove 19. When the user needs to remove the protective plate 21, the multiple auxiliary plates 25 can increase the contact area between the user and the protective plate 21, making it easier to move, thereby achieving the effect of assisting the use of the protective plate 21.

[0036] The working principle and usage process of this utility model are as follows: In use, first move the fixed rod 11 on either side of the steel pipe towards the support column 2. This moves the movable rod 162 into the support column 2, increasing the distance between the fixed rods 11. This allows the user to align the steel pipe with the support rod 14. When moving the fixed rod 11, the spring 23 is compressed and contracts. When the user stops applying force to the fixed rod 11, the spring 23's rebound force pushes the fixed rod 11 back to its original position, simultaneously reinforcing the steel pipe installation to some extent. After the steel pipe is placed horizontally, align the other end of the steel pipe with another support rod 14, facilitating the user's placement of the steel pipe. The movable groove 161 restricts the movement direction of the movable rod 162, while the rotation of the fixed rod 11 drives the movable rod 162. 2. During rotation, the moving rod 162 can move inside the moving slot 161. After the user places the steel pipe on the fixed rod 11, the control panel 152 transmits an opening electrical signal to the third motor 151. When the third motor 151 receives the electrical signal from the control panel 152, it will start to rotate. The output end of the third motor 151 rotates to drive the bidirectional lead screw 12 to rotate, which in turn allows the moving plate 13 to move up and down, thereby quickly fixing the steel pipe between the support columns 2. When the bidirectional lead screw 12 rotates, the auxiliary rod 17 can restrict the direction of movement of the moving plate 13, so that the moving plate 13 will not rotate with the bidirectional lead screw 12, thus avoiding the situation where the bidirectional lead screw 12 rotates and the moving plate 13 follows it, thereby achieving the effect of full spraying.

[0037] In summary, this surface coating device for steel pipe production, by setting up a bidirectional lead screw 12, a moving plate 13, and a fixed rod 11, first aligns the notch of the steel pipe with the fixed rod 11, moves the fixed rod 11 to the inside of the steel pipe, and then rotates the bidirectional lead screw 12. The moving plate 13 moves up and down due to the rotation of the bidirectional lead screw 12 while the moving plate 13 remains stationary. Since the moving plate 13 is fixedly connected to the fixed rod 11, the fixed rod 11 can be fixed according to the diameter of the steel pipe, allowing the entire surface of the steel pipe to be coated. This solves the problem that while the coating device can coat most of the steel pipe surface, the areas clamped on both sides of the steel pipe cannot be coated, requiring the user to manually rotate the angle of the steel pipe or manually apply the coating to the uncoated areas, thus limiting the coating equipment's capabilities.
