Commonly used ones include water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. During the production process of pipes, in order to prevent pipes from rusting and make them more beautiful, painting treatment is carried out on the pipes.

[0003] Currently, during the painting process of the surfaces of some shorter pipes, manual painting is usually used, which makes the painting operation more troublesome and there are also problems with poor painting quality on the pipe surfaces.

[0004] To solve the above problems, this application provides an automatic pipe surface painting device. Summary of the Invention

[0005] The automatic pipe surface painting device provided by this application adopts the following technical solutions:

A driving component is arranged between the lower sides of the two groups of supporting components. A painting component is arranged at the rear end of the main frame;

[0007] The supporting component includes a rotating rod that is rotatably sleeved through the inner cavity on one side of the upper end of the main frame. Discs are fixedly connected to both ends of the rotating rod. A cylinder is fixedly sleeved through the central positions of the rotating rod and the two discs. A clamping disc is fixedly installed at the driving end on one side of the cylinder. A retaining ring is fixedly connected to the end surface of the clamping disc facing away from the cylinder, and the retaining ring is located inside the main frame. A first gear is fixedly sleeved on the outer wall of the middle part of one of the discs. The first gear is located outside the main frame, and a second gear is provided directly below the first gear. A transmission chain is jointly meshed with the outer ends of the first gear and the second gear. Three connecting rods are evenly fixedly connected to the periphery of the opposite end surfaces of the two discs in a circumferential manner. The same side ends of the three connecting rods on each side are fixedly connected with sliding balls, and the three sliding balls on each side jointly slide through a sliding rail ring. The two sliding rail rings are both located outside the rotating rod, and the two sliding rail rings are respectively fixedly installed at the inner and outer surface positions of one side end of the main frame.

[0008] Through the above technical solutions, the clamping disc and the retaining ring achieve the clamping and positioning effect on the pipe.

[0009] Further, the driving assembly includes a dual-axis motor disposed inside the bottom end of the main frame. The driving ends on both sides of the dual-axis motor are each connected to a rotating shaft. One side of each of the two rotating shafts is respectively rotatably sleeved through the inner cavities on both sides of the bottom end of the main frame, and the opposite ends of the two rotating shafts are respectively fixedly connected to two second gears.

[0035] Embodiment:

[0036] An automated spray painting device for the surface of pipes is disclosed in the embodiments of the present application. Please refer to Figures 1 - 4 , which includes a main frame 1. Two sets of supporting components are symmetrically arranged at both ends of the main frame 1. A driving component is arranged at the position between the lower sides of the two sets of supporting components, and a spray painting component is arranged at the rear end of the main frame 1;

[0037] The supporting component includes a rotating rod 2 rotatably sleeved through the inner cavity on one side of the upper end of the main frame 1. Disks 3 are fixedly connected to both ends of the rotating rod 2. A cylinder 4 is fixedly sleeved through the central positions of the rotating rod 2 and the two disks 3. A clamping disk 5 is fixedly installed at the driving end on one side of the cylinder 4. A snap ring 6 is fixedly connected to the end surface of the clamping disk 5 facing away from the cylinder 4. The snap ring 6 is located inside the main frame 1. A first gear 7 is fixedly sleeved on the outer wall of the middle part of one of the disks 3. The first gear 7 is located outside the main frame 1. A second gear 8 is provided directly below the first gear 7. A drive chain 9 is meshed with the outer ends of the first gear 7 and the second gear 8. Three connecting rods 10 are fixedly connected to the periphery of the opposite end surfaces of the two disks 3 in a circumferentially uniform manner. Sliding balls 11 are fixedly connected to the same side ends of the three connecting rods 10 on each side. A slide rail ring 12 is slidably sleeved on one side of the three sliding balls 11 on each side. The two slide rail rings 12 are both located outside the rotating rod 2. The two slide rail rings 12 are respectively fixedly installed on the inner and outer surface positions of one side end of the main frame 1. The cooperation of the connecting rods 10, the sliding balls 11 and the slide rail rings 12 on one side of each disk 3 can prevent the disk 3 from directly contacting the surface of the main frame 1 and causing wear and large frictional resistance under the limiting rotation of the disk 3, thereby further improving the overall use effect.

[0038] The driving component includes a double-shaft motor 13 arranged at the inner position of the bottom end of the main frame 1. Shafts 14 are connected to the driving ends on both sides of the double-shaft motor 13. One sides of the two shafts 14 are respectively rotatably sleeved through the inner cavities on both sides of the bottom end of the main frame 1. The opposite ends of the two shafts 14 are respectively fixedly connected to the two second gears 8. A backing plate is fixedly installed on the outer wall of the bottom end of the double-shaft motor 13. The bottom of the backing plate is fixedly connected to the inner wall of the bottom end of the main frame 1. A protective cover 15 is arranged outside the double-shaft motor 13.

[0039] The protective cover 15 includes a cover body 151 sleeved outside the double-shaft motor 13. The cover body 151 is in a box-shaped structure with a hollow rectangle and no bottom end face. At the middle parts of the front and rear sides of the bottom end of the cover body 151, extension blocks 152 are fixedly installed. One side of each of the two extension blocks 152 is screwed and fixed to the inner wall of the bottom end of the main body frame 1 through a locking screw. Through slots 153 are respectively formed in a penetrating manner at the middle parts of the left and right sides of the bottom end of the cover body 151, and the two through slots 153 are respectively sleeved on the outer sides of the two rotating shafts 14 close to the double-shaft motor 13. Heat dissipation slots are respectively formed in a penetrating manner at the central positions of the front and rear sides of the cover body 151, and a plurality of louvers 154 are vertically, evenly and spacedly fixedly installed on the inner walls of each side of the heat dissipation slots. The setting of the protective cover 15 can protect the double-shaft motor 13 by means of the cover body 151, and can prevent it from being damaged by extrusion and affected by paint dripping. The extension blocks 152 and the locking screws on the cover body 151 can facilitate its disassembly, positioning, and at the same time, the two sides of the cover body 151 can accommodate and sleeve one side of the two rotating shafts 14 through the through slots 153. The setting of the heat dissipation slots and the louvers 154 on the cover body 151 can achieve an effective heat dissipation effect during the operation of the double-shaft motor 13. The main body frame 1 is in a "U"-shaped plate body structure, and base blocks 16 in a frustum shape are fixedly connected to the two sides of the bottom of the main body frame 1.

[0040] Please refer to Figure 1 and Figure 5 , the painting assembly includes a rectangular frame 17 fixedly installed at the rear end face position of the lower side of the main body frame 1. A threaded rod 18 is rotatably installed at the central position inside the rectangular frame 17. One end of the threaded rod 18 is connected to a driving motor 19, and the driving motor 19 is fixedly installed on the outer surface of one side of the rectangular frame 17. A moving seat 20 is screwed and installed on the outer wall of the threaded rod 18. The moving seat 20 is slidably sleeved on the inner wall of the rectangular frame 17, and a vertical plate 21 is fixedly connected to the top of the moving seat 20. A spraying gun 22 is fixedly sleeved at the upper end of the vertical plate 21, and a paint pipe 23 is connected to the rear end of the spraying gun 22. Limiting sliding grooves are respectively formed in an embedded manner at the middle parts of the front and rear sides of the moving seat 20. Limiting sliding bars are slidably sleeved through the inner walls of the two limiting sliding grooves, and the two limiting sliding bars are respectively fixedly installed at the two sides of the inner wall of the rectangular frame 17.

[0041] The implementation principle of the embodiment of this application is as follows: When in use, while hoisting the shorter pipe to the position between the two clamping discs 5, under the relative synchronous drive of the clamping discs 5 and the clamping rings 6 by the two cylinders 4 on both sides, the two clamping discs 5 indirectly clamp the two ends of the pipe stably. At this time, the two clamping rings 6 are respectively movably clamped at the inner wall positions of the openings at both ends of the pipe. Then, while starting the biaxial motor 13, the two rotating shafts 14 drive the two second gears 8 to rotate synchronously. At this time, due to the meshing states of the transmission chains 9 on both sides with the second gears 8 and the first gears 7, the first gears 7 on both sides are driven to rotate self - actively, indirectly causing the positioned pipe to perform a passive self - rotation movement. And during this process, each connecting rod 10 is driven by the disc 3, causing each sliding ball 11 to perform a circular sliding movement on the outer surface of the corresponding slide rail ring 12;

[0042] Meanwhile, while the paint pipe 23 supplies paint to the spray gun 22 (the paint pipe 23 is a flexible material hose, and one end of it is connected to an external paint spraying raw material supply device), the surface of the pipe can be painted. And under the drive of the drive motor 19 on the threaded rod 18, and the sliding limit states of the two limit slide bars and limit chutes on the moving seat 20, the moving seat 20 indirectly performs a linear reciprocating movement on the inner wall of the rectangular frame 17. Thus, by driving the spray gun 22 to perform a reciprocating movement through the vertical plate 21, the automatic and uniform painting of the pipe surface can be achieved.

[0043] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
