Description

Technical Field

[0001] This utility model relates to the field of workpiece spraying technology, and more specifically to an online rolling spraying device for round tube workpieces. Background Technology

[0002] In order to improve the appearance and corrosion resistance of pipe fittings, paint is sprayed on the surface of the pipe fittings. When spraying paint, a rolling spraying device is used to drive the pipe fittings to rotate. During the rotation, the surface of the pipe fittings is fully sprayed.

[0003] A search revealed an existing patent (publication number: CN220294972U) that discloses an online rolling spraying device for plastic-coated composite steel pipes. In use, the plastic-coated steel pipe is placed on multiple drive wheels on the circumference of two rotating rods. Because the drive wheels have annular friction protrusions on their circumferences, the drive wheels rotate while simultaneously causing the plastic-coated steel pipe to roll on the processing table. Then, a spraying mechanism is used to spray the rolling plastic-coated steel pipe. However, the inventors discovered the following problem with the existing technology during the development of this invention: In the above-mentioned spraying device, the steel pipe is laid on the surface of the drive wheels, and the rotation of the drive wheels is used to drive the pipe to rotate. However, after spraying the pipe surface, the undried paint comes into contact with the drive wheels, which damages the paint surface of the pipe, thus affecting the paint spraying effect.

[0004] In view of this, the present invention proposes an online rolling spraying processing device for round tube workpieces to solve this problem. Utility Model Content

[0007] The pipe positioning assembly includes a geared motor fixedly installed on the right wall of the left side plate. A left cone seat is fixedly installed on the output shaft surface of the geared motor. A hydraulic rod is embedded in the surface of the right side plate. A connecting box is fixed to the telescopic end of the hydraulic rod. A right cone seat is rotatably connected to the left end of the connecting box. The positions of the left and right cone seats correspond to each other. A jacket is fixedly installed on the right side of the geared motor. The jacket is rotatably connected to the output end of the geared motor through a sealed bearing. A left air supply channel extending to the tip of the left cone seat is opened on the output shaft surface of the geared motor. A hot air blower is fixedly installed on the back of the left side plate. The air outlet of the hot air blower is connected to the inner cavity of the jacket through a pipe. A right air supply channel extending into the inside of the connecting box is opened at the tip of the right cone seat.

[0012] Furthermore, a second limiting slide bar is fixedly installed between the two mounting plates, and the right side plate is slidably connected to the second limiting slide bar; by setting the second limiting slide bar, the movement path of the right side plate can be restricted to ensure stable movement of the right side plate.

[0013] Furthermore, a hydraulic lifting rod is embedded in the surface of the base, and a lifting platform is fixedly installed at the telescopic end of the hydraulic lifting rod. The surface of the lifting platform is provided with an arc-shaped groove for external pipe fittings to be placed in. By setting up the hydraulic lifting rod and the lifting platform, when loading the pipe fittings to be processed, the pipe fittings are placed in the arc-shaped groove in advance, and then the lifting platform is raised and lowered by controlling the extension of the hydraulic lifting rod, so as to facilitate the loading of pipe fittings.

[0025] By setting up a hydraulic lifting rod 20 and a lifting platform 21, when loading the pipe fittings to be processed, the pipe fittings are placed in the arc-shaped groove in advance. Then, by controlling the extension of the hydraulic lifting rod 20, the lifting platform 21 is raised and lowered, so as to facilitate the loading of the pipe fittings.

[0026] A limit post 22 is fixedly installed at the bottom of the lifting platform 21, and a limit cylinder 23 is fixedly installed at the top of the base 1. The limit post 22 is inserted into the top of the limit cylinder 23.

[0027] Furthermore, by inserting the limiting post 22 inside the limiting cylinder 23, the movement path of the lifting platform 21 can be limited, thereby improving the stability of the lifting platform 21 during lifting.

[0028] The upper surface of the base 1 is provided with a left side plate 2 and a right side plate 3 respectively. A pipe positioning assembly is provided between the left side plate 2 and the right side plate 3. A spraying assembly is provided on the top of the left side plate 2.

[0029] The pipe positioning assembly includes a geared motor 4 fixedly installed on the right wall of the left side plate 2. A left cone seat 5 is fixedly installed on the output shaft surface of the geared motor 4. A hydraulic rod 6 is embedded in the surface of the right side plate 3. A connecting box 7 is fixed to the telescopic end of the hydraulic rod 6. A right cone seat 8 is rotatably connected to the left end of the connecting box 7. The positions of the left cone seat 5 and the right cone seat 8 are corresponding. A sleeve 9 is fixedly installed on the right side of the geared motor 4. The sleeve 9 is rotatably connected to the output end of the geared motor 4 through a sealed bearing.

A right air supply channel 12 extending to the inside of the connecting box 7 is opened at the tip of the right cone seat 8. The air inlet of the hot air blower 11 is connected to the inner cavity of the connecting box 7 through a hose.

[0030] The spraying assembly includes a top frame 13 welded to the top of the left side plate 2. A spraying pipe 14 is embedded on the surface of the top frame 13.

The hot air is then transported into the workpiece through the left air supply channel 10 and then returns to the air inlet of the hot air blower 11 through the right air supply channel 12. This achieves the purpose of continuously heating the workpiece, thereby increasing the drying speed of the paint on the workpiece surface. After the paint is dried, it is convenient for the pipes to be stored later, and there will be no situation where the paint on the surface of the pipes is stuck together, thus ensuring the quality of the workpiece spraying process.

[0035] The surfaces of both the left cone seat 5 and the right cone seat 8 are covered with a number of anti-slip toothed strips 15 in a circumferential array.

[0036] By setting the anti-slip rack 15, the friction between the left cone seat 5 and the right cone seat 8 when clamping the pipe can be increased, ensuring that the pipe can rotate when the left cone seat 5 rotates.

[0037] The left side plate 2 is fixedly connected to the base 1, and the right side plate 3 is movably connected to the base 1. Two mounting plates are fixedly installed on the surface of the base 1, and a transverse lead screw 17 is rotatably connected between the two mounting plates.

[0039] A second limiting slide bar 19 is fixedly installed between the two mounting plates, and the right side plate 3 is slidably connected to the second limiting slide bar 19.

[0040] By setting the second limit slide bar 19, the movement path of the right side plate 3 can be restricted, ensuring that the right side plate 3 moves stably.

[0041] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model.
