Description

Technical Field

[0001] The utility model provides a spraying machine for metal pipe fittings, and relates to the technical field of pipe fitting spraying. Background Art

[0002] Metal pipes are pipes made from metal. Through various processing techniques, they can be transformed into metal fittings with diverse functions, which are used in various fields of society, such as construction and machinery manufacturing. During the production and processing of metal pipe fittings, coatings are often applied to the outside of the fittings to protect them from corrosion, oxidation, and other environmental damage, as well as to enhance their aesthetics.

[0003] After searching, the Chinese patent with publication number CN220879318U discloses a surface spraying device for metal pipe products. When performing surface spraying operations on metal pipe fittings, this patent uses a clamp to clamp the two ends of the metal pipe product. After the spraying operation is completed, the limit box on one side of the fixed seat is separated from the clamping of the metal pipe fitting, and the hydraulic rod 2 pushes the slide in the opposite direction to drive the movable seat away from the fixed seat, and the hydraulic rod 1 is started to push the movable seat away from the paint spraying frame, so that one end of the metal pipe fitting can be tilted and extended to one side of the spraying equipment, making it convenient for the staff to receive the metal pipe product that has been sprayed, so that there is no need to remove the metal pipe product near the area with a strong smell of sprayed paint.

[0004] Although the aforementioned patent eliminates the need for workers to approach work areas with a strong paint odor, it still has some drawbacks in actual use: the fixture structure in the aforementioned patent is unstable and is manually driven. Workers must constantly turn the crank handles on both sides each time they load and unload materials. This makes it impossible to ensure that the force on both sides is equal when clamping and fixing the pipe. The pipe may become loose when it is subsequently rotated, and manual operation is inefficient. Furthermore, the aforementioned patent includes a spray rack. Although multiple nozzles are arranged on the spray rack, the nozzles and spray range are fixed, so it can only spray pipes of a fixed length, resulting in a relatively limited scope of application and a lack of practicality. Therefore, we propose a sprayer for metal pipes. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing spraying equipment has poor fixture stability, is cumbersome to operate and can only spray pipes of fixed length.

[0006] The cam is connected to the outer cover of the spraying machine to move the spraying machine toward the outer cover, and the cam is connected to the guide rail at the inner cover of the spraying machine to move the spraying machine toward the outer cover.

[0007] Preferably, a rotating seat is rotatably provided on one side of the spray seat and a hydraulic cylinder is fixedly connected to the other side. A rotating component is connected to the outer side of the rotating seat. The telescopic end of the hydraulic cylinder passes through the side wall of the spray seat. Two groups of clamps are provided, one group of clamps is rotatably connected to the telescopic end of the hydraulic cylinder, and the other group of clamps is fixed to the rotating seat.

[0008] Preferably, the rotating assembly includes a rotating shaft coaxially fixed to the rotating seat, a sprocket 1 coaxially fixed to the rotating shaft, a driving motor, a sprocket 2 coaxially fixed to the output shaft of the driving motor, and a chain connected between the sprocket 1 and the sprocket 2.

[0009] Preferably, a shield is fixedly connected to the spray seat, the shield is arc-shaped and is arranged on the outside of the electric guide rail, a slide groove is opened on the shield along the length direction, and the end of the nozzle away from the connecting hose passes through the slide groove.

[0010] Preferably, at least two top plates are provided.

[0011] Preferably, the outer side of the top plate is wrapped with a rubber sleeve.

[0012] Beneficial effects of the utility model:

[0013] The clamp adopts electric type, using electric push rod as the power source to push the top plate against the inner wall of the pipe to fix it. The structure is more stable and more convenient to use. It can also be applied to pipes of different diameters and lengths.

[0014] The nozzle is moved by an electric guide rail, and can be used for spraying with pipes of different lengths, thus expanding the scope of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1 to 5 The utility model provides a spraying machine for metal pipe fittings, including a spraying seat 1, a clamp 9 arranged on the spraying seat 1 and a spraying mechanism, the clamp 9 includes an end seat 16, an electric push rod 17 fixed to the inner side of the end seat 16, a guide sleeve 18 fixed to the outer side of the end seat 16, a push head 22 slidably placed on the inner side of the guide sleeve 18, and a top plate 19 arranged circumferentially around the guide sleeve 18, the telescopic end of the electric push rod 17 passes through the side wall of the end seat 16 and is fixed to the end of the push head 22, a push rod 20 is hinged between the top plate 19 and the push head 22, and an oblong hole 24 is opened on the side wall of the push rod 20, a rectangular through hole 21 is opened on the side wall of the guide sleeve 18 to match the push rod 20, and a limiting shaft 23 matching the oblong hole 24 is fixed to the inner side of the rectangular through hole 21, specifically, as Figure 4 、 Figure 5As shown, the clamp 9 is placed inside the end of the pipe fitting, and the electric push rod 17 is started to push the push head 22 to move inside the guide sleeve 18. Due to the restriction of the limit shaft 23, the push rod 20 will swing around the limit shaft 23, thereby pushing the top plate 19 outward so that the top plate 19 can contact the inner wall of the pipe fitting. As the electric push rod 17 continues to advance, the top plate 19 is pressed against the inner wall of the pipe fitting, so that the entire clamp 9 is tightened on the inside of the pipe fitting, which can not only fix the pipe fitting, but also be suitable for pipes of different diameters.

[0023] Furthermore, if Figure 4 、 Figure 5 As shown, at least two top plates 19 are provided, and a rubber sleeve is wrapped around the outside of the top plate 19. Specifically, at least two fulcrum points are provided to fix the pipe fittings. By wrapping the rubber sleeve, the friction between the top plate 19 and the pipe fittings is increased, thereby improving the fixing effect.

[0024] Furthermore, if Figure 1 、 Figure 2 As shown, the spraying seat 1 is rotatably provided with a rotating seat 5 on one side and a hydraulic cylinder 11 is fixedly connected to the other side. A rotating assembly is connected to the outer side of the rotating seat 5. The telescopic end of the hydraulic cylinder 11 passes through the side wall of the spraying seat 1. The clamps 9 are provided in two groups, one of which is rotatably connected to the telescopic end of the hydraulic cylinder 11, and the other group of clamps 9 is fixed to the rotating seat 5. Specifically, the hydraulic cylinder 11 can drive one group of clamps 9 to move left and right, thereby adapting to pipes of different lengths. After the pipe is fixed, the rotating seat 5 is driven to rotate by the rotating assembly, thereby driving the pipe to rotate.

[0025] Furthermore, if Figure 1 、 Figure 2 As shown, the rotating assembly includes a rotating shaft coaxially fixed to the rotating base 5, a sprocket 1 6 coaxially fixed to the rotating shaft, a drive motor 8, a sprocket 2 7 coaxially fixed to the output shaft of the drive motor 8, and a chain 10 connected between the sprocket 1 6 and the sprocket 2 7. Specifically, the drive motor 8 drives the sprocket 2 7 to rotate, the sprocket 2 7 drives the sprocket 1 6 to rotate through the chain 10, the sprocket 1 6 drives the rotating shaft to rotate, and the rotating shaft drives the rotating base 5 to rotate.

[0026] Furthermore, if Figure 1 、 Figure 3As shown, the spray mechanism includes an electric guide rail 2 fixed to one side of the spray base 1. The electric guide rail 2 includes a slide 14, to which a fixed bracket 15 is fixed. A nozzle 13 is fixed inside the fixed bracket 15. The nozzle 13 is provided with a nozzle at one end and is connected to a connecting hose 3, a material pump, and a material storage tank at the other end. Specifically, the electric guide rail 2 adopts existing technology. The electric guide rail 2 drives the nozzle 13 to move freely, coordinating with the rotation of the pipe, thereby spraying all around the pipe. It can also be used for pipes of different lengths.

[0027] Furthermore, if Figure 1 、 Figure 2 As shown, the spray station 1 is further fixed with a shield 4. The shield 4 is arc-shaped and covers the outer side of the electric guide rail 2. The shield 4 has a slide groove 12 along its length. The end of the nozzle 13 away from the connecting hose 3 passes through the slide groove 12. Specifically, the shield 4 is used to prevent paint from falling onto the electric guide rail 2.

[0028] Working Principle: First, place one end of the pipe outside the fixture 9 on the side of the rotating base 5. Activate the electric push rod 17 to tighten the fixture 9 against the inside of the pipe. Then activate the hydraulic cylinder 11 to drive the other set of fixtures 9 to the other end of the pipe. Activate the electric push rod 17 again to tighten the fixture 9 against the inside of the pipe, thereby securing both ends of the pipe. Then activate the drive motor 8 to rotate the pipe. Activate the pump to draw the paint from the storage tank into the connecting hose 3 and nozzle 13, and then spray it out from the nozzle. Activate the electric guide rail 2 to move the nozzle 13 along the length of the pipe, spraying all around the pipe.

[0029] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
