[0030] In the description of the present invention, it should be understood that the terms "length," "width," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," and the like, indicating positions or location relationships, are based on the positions or location relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. Furthermore, in the description of the present invention, "plurality" means two or more, unless otherwise expressly and specifically defined.

[0031] The present invention provides Figure 1-8The illustrated assembly-type automatic sleeve unloading device comprises a workbench 1, a limiting cylinder 2 is provided above the workbench 1, an inclined unloading channel 3 is provided on one side of the limiting cylinder 2, a cutting mechanism is installed on the workbench 1, and an unloading mechanism is installed on the workbench 1; the cutting mechanism comprises a movable platform 4 located between the limiting cylinder 2 and the inclined unloading channel 3, a cutting knife 5 is connected to the upper end of the movable platform 4 by bolts, first rolling bearings 6 are installed at both ends of the limiting cylinder 2, and the lower end of the first rolling bearing 6 is installed on the workbench 1 through a first support rod 7, a plurality of first limiting holes 8 are opened on the limiting cylinder 2, a first limiting wheel 9 is installed on the first limiting hole 8, and a driving frame 10 is installed on the workbench 1. The driving frame 10 can drive the limiting cylinder 2 to rotate, and the driving frame 10 can drive the moving platform 4 to reciprocate; the loading and unloading mechanism includes a loading cylinder 11 located at the rear side of the limiting cylinder 2, and a plurality of second limiting holes 12 are opened on the loading cylinder 11, and a second limiting wheel 13 is installed on the second limiting hole 12. A pushing platform 14 is installed at the lower end of the limiting cylinder 2, and the driving frame 10 can drive the pushing platform 14 to reciprocate. A rotating platform 15 is installed between the inclined unloading channel 3 and the moving platform 4, and a plurality of rotatable limiting rods 16 are installed on the rotating platform 15. When the moving platform 4 reciprocates, it can drive the rotating platform 15 to rotate in one direction, and the first limiting wheel 9 and the second limiting wheel 13 can only rotate in one direction;

[0032] The process of this device for unloading steel pipes is as follows: one end of the steel pipe is passed through the loading cylinder 11 and the limit platform 2 to one side of the limit rod 16, and one end of the limit rod 16 is extended into the steel pipe. The limit cylinder 2 can be driven to rotate by the driving frame 10, and the steel pipe can be limited by the first limit wheel 9, which can drive the steel pipe to rotate. The driving frame 10 can drive the movable platform 4 to move, and the movable platform 4 can drive the cutting knife 5 to move, which can facilitate the cutting of the steel pipe. The cut steel pipe remains on the limit rod 16 to prevent the steel pipe from being thrown away. The movable platform 4 is then driven back to its original position by the driving frame 10. When the movable platform 4 returns to its original position, the rotating platform 15 can be driven to rotate, so that the rotating platform 15 and the limit rod 16 can drive the steel pipe to move, and the next limit rod 16 is rotated to one end of the steel pipe. On the other hand, the cut steel pipe is rotated to the side of the inclined unloading channel 3, which makes unloading easier. When the steel pipe rotates, the friction between the steel pipe and the second limiting wheel 14 can drive the loading barrel 11 to rotate, and then the driving frame 10 drives the pushing platform 14 and the loading barrel 11 to move in the direction close to the limiting barrel 2. The second limiting wheel 13 does not rotate at this time, and the friction between the second limiting wheel 13 and the steel pipe can drive the steel pipe to be loaded. At this time, the first limiting wheel 9 can rotate, which is convenient for loading the steel pipe. After the loading is completed, the pushing platform 14 and the loading barrel 11 can return to their original positions. At this time, the first limiting wheel 9 does not rotate, and the friction between the first limiting wheel 9 and the steel pipe can prevent the steel pipe from moving in the opposite direction. The rotation of the second limiting wheel 13 can reduce the friction when the loading barrel 11 returns to its original position.

[0033] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 , Instruction Manual Figure 4 , Instruction Manual Figure 6 and instructions attached Figure 7 The driving frame 10 includes a dual-axis output motor 17 installed on the upper surface of the workbench 1, and a first gear 18 is installed at one output end of the dual-axis output motor 17.

A dual-output reducer 20 is provided on one side of the dual-axis output motor 17 and is installed on the upper surface of the workbench 1. The rotating end of the dual-axis output motor 17 is connected to the power input end of the dual-output reducer 20. Guide grooves 21 are opened on both sides of the lower end of the mobile platform 4, and a guide block 22 is installed on the upper end of the workbench 1.

The second rack 24 is installed on the mobile platform 4 through a connecting rod 25. A transmission shaft 26 is provided on one side of the mobile platform 4, and a second rolling bearing 27 is installed at the lower end of the transmission shaft 26. The lower end of the second rolling bearing 27 is installed On the workbench 1, a third gear 28 is installed on the transmission shaft 26, and the third gear 28 can mesh with the first rack 23. A fourth gear 29 is provided above the third gear 28 and is installed on the transmission shaft 26. The fourth gear 29 can mesh with the second rack 24. A first bevel gear 30 is installed at the lower end of the transmission shaft 26, and a second bevel gear 31 is installed at one output end of the dual-output reducer 20. The second bevel gear 31 meshes with the first bevel gear 30. The other output end of the dual-output reducer 20 is connected to a transmission rod 32, and a third rolling bearing 33 is installed at one end of the transmission rod 32. The lower end of the third rolling bearing 33 is installed on the workbench 1 through a second support rod 34. The transmission rod 32 can drive the push table 14 to move back and forth.

When the third gear 28 and the first rack 23 are disconnected, the fourth gear 29 can mesh with the second rack 24.

[0034] The process of the driving frame 10 driving the limiting cylinder 2 to rotate and the moving platform 4 to move is as follows: the dual-axis output motor 17 is started to rotate, the dual-axis output motor 17 can drive the first gear 18 to rotate, the first gear 18 and the second gear 19 are meshed, and then the second gear 19 and the limiting cylinder 2 are driven to rotate, the dual-axis output motor 17 can also drive the dual-output end reducer 20 to rotate, after the dual-output end reducer 20 is decelerated, the second bevel gear 31 can be driven to rotate, the second bevel gear 31 is meshed with the first bevel gear 30, and then the transmission shaft 26 can be driven to rotate, the transmission shaft 26 can drive the third gear 28 and the fourth gear 29 to rotate, and then the third gear 28 can be firstly engaged with the first gear The gear 23 is engaged, which can drive the first rack 23 and the movable platform 4 to move. The guide groove 21 and the guide block 22 can ensure the moving direction of the movable platform 4. When the movable platform 4 moves, the cutting knife 5 can cut the steel pipe. Since the third gear 28 has teeth only at one-fourth of the position, when the third gear 28 is disconnected from the first rack 23, the movable platform 4 stops moving, and then the fourth gear 29 can be engaged with the second rack 24, thereby driving the second rack 24 and the movable platform 4 to move in the opposite direction, thereby facilitating the movable platform 4 to return to its original position. The dual-output reducer 20 can also drive the transmission rod 32 to rotate, and the transmission rod 32 can drive the push platform 14 to move.

Only one-quarter of the fifth gear 44 has teeth. When the fourth gear 29 is disconnected from the second rack 24, the fifth gear 44 can mesh with the third rack 45. When the fifth gear 44 is disconnected from the third rack 45, the third gear 28 can mesh with the first rack 23.

[0036] The process of the transmission rod 32 driving the pushing platform 14 to move is as follows: when the transmission rod 32 rotates, it can drive the fourth bevel gear 43 to rotate, and the fourth bevel gear 43 is meshed with the third bevel gear 42, which can then drive the third bevel gear 42, the rotating rod 40, and the fifth gear 44 to rotate.
