[0037] like Figure 1-11 As shown, a seamless steel pipe efficient double-channel packaging device includes a clamping device, two first conveyor lines 1, two second conveyor lines 13, and a bundling device 14 located on the second conveyor line 13. The first conveyor line 1 has the same structure as the second conveyor line 13. The upper side of the first conveyor line 1 is connected to a plurality of conveyor shafts 102 arranged left and right through a bearing. Chain drive or belt drive is adopted between the conveyor shafts 102, and one of the conveyor shafts 102 is connected to a power motor. A plurality of groups of rollers 101 are arranged on the upper side of the first conveyor line 1, each group of rollers 101 has two, and the two rollers 101 are arranged in an eight-shaped shape. The lower end of the roller 101 is rotatably connected to a fixing seat 103 fixed to the first conveyor line 1 by bolts. The clamping device can The seamless steel pipe can be clamped onto the two first conveyor lines 1, the seamless steel pipe is in contact with the roller 101 and the conveyor shaft 102, the seamless steel pipe placed on the first conveyor line 1 is distributed in a hexagonal shape, the first conveyor line 1 can move the seamless steel pipe to the second conveyor line 13, and protective cover installation devices 2 are arranged on both sides of the second conveyor line 13, the protective cover installation device 2 includes a storage box 26, an adjustment plate 21 capable of multi-directional displacement adjustment on the storage box 26, a rotating disk 210 connected to the adjustment plate 21 through a bearing, and a plurality of suction cover assemblies 22 distributed in a hexagonal shape, the suction cover assembly 22 is arranged on the rotating disk 210, the adjustment plate 21 is connected to the driving motor 24 through bolts, and the driving motor 24 is connected to the rotating disk 210 through teeth;

[0038] The storage box 26 is provided with a hexagonal placement slot 28, and the cover body 215 is vertically adsorbed in the placement slot 28. The adjustment plate 21 is provided with a conveying slot 15 connected to the placement slot 28. The conveying slot 15 is connected to the discharge port of the vibrating material distribution plate 12 located on one side of the adjustment plate 21. The cover body 215 in the vibrating material distribution plate 12 passes through the conveying slot 15 and vertically enters the placement slot 28. The suction cover assembly 22 can adsorb the cover body 215 located in the placement slot 28. The maximum diameter of the cover body 215 is the same as the maximum diameter of the seamless steel pipe.

[0039] When in use, the clamping device clamps the seamless steel pipe and places it on one of the first conveyor lines 1 until the side shape of the seamless steel pipe on the first conveyor line 1 is a regular hexagon. Then, the conveying shaft 102 of the first conveyor line 1 rotates and drives the seamless steel pipe to move to the second conveyor line 13. The bundling device 14 bundles the seamless steel pipe, and the suction cover assembly 22 sucks the cover body 215 in the placement groove 28. Then, the adjustment plate 21 moves to the right. After the right movement is completed, the drive motor 24 works and drives the rotating disk 210 to rotate. The rotation angle of the rotating disk 210 can be set independently. After the rotating disk 210 rotates, the vibrating material distribution plate 12 transports the cover body 215 to the placement through the conveying groove 15 In the slot 28, the cover suction assembly 22 that has not sucked the cover body 215 at this time sucks the cover body 215 again, and according to the above process, after the rotating disk 210 rotates 360°, the cover suction assembly 22 sucks all the cover bodies 215, and then the adjustment plate 21 drives the cover body 215 to move out of the placement slot 28 through the rotating disk 210 and the cover suction assembly 22, and then the adjustment plate 21 drives the cover body 215 to move up to the two ends of the seamless steel pipe on the second conveyor line 13. At this time, the adjustment plate 21 drives the cover body 215 to move toward the seamless steel pipe, and the cover body 215 is inserted into the seamless steel pipe. After that, the cover suction assembly 22 no longer sucks the cover body 215 and resets to one side of the placement slot 28. At this time, the seamless steel pipe packaging is completed;

[0040] During the packaging process, the clamping device places the seamless steel pipe on another first conveyor line 1, thereby accelerating the packaging speed.

[0041] In this embodiment, the storage box 26 is fixed with two vertical plates 25 by bolts, and the vertical plates 25 are arranged on the side of the storage box 26 that is connected to the placement groove 28. The vertical plates 25 are provided with sliding grooves on the opposite sides. The side of the vertical plates 25 is connected with an electric telescopic rod 251 located on the storage box 26 by bolts to drive the cover body 215 to disengage from the placement groove 28 and not to contact the storage box 26 when the cover body 215 moves up. The side of the adjustment plate 21 is fixed with a sliding plate by bolts, and the sliding plate is slidably connected with the sliding groove. The front side of the sliding plate is provided with a toothed plate 211 fixed to the adjustment plate 21 by bolts. The side of the vertical plate 25 is installed with a driving motor 24 through a supporting plate. The driving motor 24 is key-connected with a driving gear 23, and the teeth of the driving gear 23 are connected to the toothed plate 211;

[0042] When it is necessary to drive the adjustment plate 21 to move right, the rod body of the electric telescopic rod 251 extends out, and the adjustment plate 21 is mobilized to move right through the vertical plate 25 and the sliding plate. When it is necessary to drive the adjustment plate 21 to move up, the rod body of the electric telescopic rod 251 is reset. When it is necessary to drive the adjustment plate 21 to move up, the drive motor 24 works and mobilizes the drive gear 23 to rotate clockwise. The drive gear 23 drives the adjustment plate 21 to move up through the tooth plate 211, and the sliding plate moves up along the slide groove. When the adjustment plate 21 needs to move down, the drive motor 24 drives the drive gear 23 to rotate counterclockwise.

[0043] In this embodiment, a mounting hole is provided at the center of the circular surface of the rotating disk 210, and a plurality of transverse plates 29 are fixed to the mounting hole by bolts. A through slot is provided on the transverse plate 29, and a plurality of fixed shafts 291 are fixed in the through slot in the transverse direction by bolts. The suction cover assembly 22 is located between the two transverse plates 29, and the upper and lower ends are inserted into the through slot and abut against the fixed shaft 291, so as to realize the fixing of the suction cover assembly 22;

[0044] When in use, the suction cover assembly 22 contacts the side wall of the through slot and the fixing shaft 291 , thereby ensuring that the suction cover assembly 22 is fixed stably.

[0045] In this embodiment, the suction cover assembly 22 includes a fixing ring 223 with both ends abutting against the fixing shaft 291, a suction plate 222 arranged concentrically with the fixing ring 223, and a plurality of fixing bolts 221 threadedly connected to the fixing ring 223. Figure 8 The four fixing bolts 221 in the cover 215 are arranged such that the diameter of the suction plate 222 is smaller than the inner diameter of the fixing ring 223. The fixing bolts 221 abut against the suction plate 222 so that the suction plate 222 is fixed to the fixing ring 223. A suction cup 218 is arranged on the side of the suction plate 222 facing the cover 215. The suction cup 218 is connected to the suction plate 222 through an electrically controlled telescopic rod 2181. The suction plate 222 is connected to the suction cup 218 through a hard telescopic tube. The suction plate 222 is connected to an air suction structure so that the suction cup 218 adsorbs the cover 215.

[0046] When the cover 215 needs to be adsorbed, the suction cup 218 contacts the side of the cover 215, wherein the side of the cover 215 is a plane. As the adjustment plate 21 moves, the suction cup 218 is squeezed and fits on the cover 215, and the suction component draws air from the suction cup 218, so that the suction cup 218 and the cover 215 are adsorbed and fixed, thereby facilitating the absorption of the cover 215. When it needs to be removed, gas is filled into the suction cup 218 through the suction component, and the suction cup 218 no longer adsorbs the cover 215. The suction cup 218 is telescopically adjusted through the electrically controlled telescopic rod 2181, which facilitates the absorption of the cover 215.

[0047] In the present embodiment, the adsorption disk 222 is provided with a through hole, which is respectively connected to the suction cup 218 and the suction structure, and an air pressure sensor 219 is arranged in the through hole. The suction structure includes a fixed plate 216B connected to the side of the adjustment plate 21 away from the storage box 26 by bolts, an air pressure adjustment plate 216A located on the side of the fixed plate 216B away from the adjustment plate 21, and a driving rod 216C fixed to the fixed plate 216B, the other end of the driving rod 216C is connected to the air pressure adjustment plate 216A, and the driving rod 216C can adopt an electric, pneumatic and hydraulic telescopic rod. The fixed plate 216B is embedded with a cylinder 217, and the cylinder 217 The through hole is connected by a pipeline, and an electric control valve is fixed on the pipeline by bolts. The cylinder 217 includes a cylinder body 2171 embedded in the fixing plate 216B, a piston 2172 located in the cylinder body 2171, and an elastic telescopic rod 2173 connected to the piston 2172. The elastic telescopic rod 2173 is a prior art, so it is not repeated here. The elastic telescopic rod 2173 is connected to the air pressure regulating plate 216A. When the electric control valve is in an open state, the elastic telescopic rod 2173 pushes the piston 2172 to move, and the spring in the elastic telescopic rod 2173 will not shrink, and the hard telescopic tube will not be deformed by the air pressure input by the cylinder 217.

[0048] When in use, the spring telescopic rod is in an extended state. When the cover 215 needs to be sucked, the driving rod 216C pushes the air pressure regulating plate 216A to move rightward. The air pressure regulating plate 216A pushes the piston 2172 to move through the elastic telescopic rod 2173. At this time, the cylinder 2171 extracts the air in the suction cup 218. When the suction cup 218 is adsorbed to the cover 215, the air pressure sensor 219 detects that the air pressure in the through hole corresponding to the suction cup 218 adsorbed to the cover 215 is reduced. At this time, the electric control valve located at the through hole is closed. Close, the rotating disk 210 rotates. During the rotation of the rotating disk 210, the driving rod 216C drives the air pressure regulating plate 216A to reset. When the electric valve connected to the cylinder 217 is in a closed state, the air pressure regulating plate 216A pushes the elastic telescopic rod 2173 to contract. At this time, the piston 2172 will not move. When the electric valve connected to the cylinder 217 is in an open state, the spring telescopic rod pushes the piston 2172 to reset. Then, the cover body 215 can be sucked according to the above process.

[0049] In this embodiment, the placement slot 28 is embedded with an electromagnet 27, and a magnetic suction plate 220 that can be adsorbed on the electromagnet 27 is embedded at the center of the left side of the cover 215. The electromagnet 27 and the suction cup 218 correspond to each other on the left and right sides. When in use, when the adjustment plate 21 is located on one side of the placement slot 28, the cover 215 falls into the placement slot 28, and then the electromagnet 27 works to adsorb the magnetic suction plate 220. According to the air pressure value detected by the air pressure sensor 219, the corresponding electromagnet 27 is controlled to no longer adsorb the magnetic suction plate 220. Plate 220, at this time, the adjustment plate 21 moves to the right and drives the corresponding cover body 215 to move out, and the magnetic plate 220 that is not adsorbed moves down, and the rotating disk 210 rotates to adjust the position of the suction cup 218. After the adjustment is completed, the suction cup 218 that is not adsorbed on the cover body 215 is driven by the electric-controlled telescopic rod 2181 to fit on the cover body 215 for adsorption. After the adsorption is completed, the electric-controlled telescopic rod 2181 drives the suction cup 218 to reset, and then follow the above process to make each suction cup 218 adsorb the cover body 215.

The upper side surface of the adjusting plate 21 is connected with the tooth grooves, and the teeth of the transmission gear 213 are connected to the teeth on the rotating disk 210.

[0051] When in use, the adjusting motor 214 drives the rotating disk 210 to rotate through the transmission gear 213 and the teeth, thereby facilitating the rotation adjustment of the rotating disk 210 .

[0052] In this embodiment, the cover bodies 215 in the placement grooves 28 are placed in a hexagonal shape and the side surfaces of the cover bodies 215 are in contact with the groove walls of the placement grooves 28 respectively, and the adjacent side surfaces of the cover bodies 215 are in contact.
