Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0027] As Figures 1-5 shown, a device for metal product powder spraying, comprising a support frame 1 and a plurality of connecting ropes 2, the connecting ropes 2 are detachably connected with longitudinal and horizontal beams, a driving mechanism is arranged between the support frame 1 and the plurality of connecting ropes 2, the driving mechanism comprises:

[0028] A fixed block 31 is rotatably connected with the support frame 1; a motor 32 is fixedly connected inside the support frame 1, the motor 32 is electrically connected with an external power supply, a coupling (not shown in the drawing) is fixedly connected at one end of a motor 32 output shaft, a drive rod 33 is fixedly arranged on one side of the fixed block 31 close to the support frame 1, and the drive rod 33 is fixedly connected with the coupling (not shown in the drawing).

[0029] A plurality of connecting columns 34 are rotatably connected with the support frame 1, and one end of each connecting column 34 is fixedly connected with the connecting rope 2. The fixed block 31 is rotatably connected with a driving column 35 inside. The driving column 35 is fixedly connected with a plurality of synchronous wheels 36. The surface of each connecting column 34 is slidably connected with a linkage wheel 38. The synchronous wheels 36 and the linkage wheels 38 are drivingly connected with a synchronous belt 37. The driving column 35 and the driving rod 33 are provided with a driving assembly for rotating the driving column 35.

[0030] It should be noted that the connecting column 34 and the linkage wheel 38 are slidably connected through a shaft and a groove. The states of the two synchronous belts 37 are different. The synchronous wheel 36 and the synchronous belt 37 on one side are drivingly connected with an opening. The synchronous wheel 36 and the synchronous belt 37 on the other side are drivingly connected with an intersection. In this way, the length of the connecting rope 2 on the connecting column 34 remains the same.

[0031] The device for spraying metal product powder is connected with the connecting rope 2 fixedly connected with the longitudinal and transverse beams and the fixed block 31 that can rotate autonomously. When the fixed block 31 rotates, it can drive the connecting rope 2 to rotate, so that the longitudinal and transverse beam to be sprayed can rotate at a specified position.

[0035] In a further embodiment, a limiting groove 61 is formed in the fixed block 31, and a plurality of limiting teeth 62 are fixedly connected in the limiting groove 61, and the limiting teeth 62 are matched with the reversing cone 52 on the driving column 35.

[0036] In a further embodiment, a sliding groove 71 is formed in the driving rod 33, a sliding shaft 72 is fixedly connected to the surface of the driving rod 51, the sliding shaft 72 is matched with the sliding groove 71, a sliding spring 73 is fixedly connected in the sliding groove 71, and the other end of the sliding spring 73 is in contact with the sliding shaft 72; when the sliding spring 73 is in a relaxed state, the distance between the sliding shaft 72 and the sliding groove 71 is the farthest.

[0037] The working principle of the utility model is: first, the connecting rope 2 is fixed with the longitudinal beam, then the motor 32 is driven, the motor 32 drives the driving rod 33 and the driving rod 51 to rotate, the driving column 35 rotates through the reversing cone 52, and the connecting column 34 can be driven to rotate through the synchronous belt 37, the connecting rope 2 is wound, the longitudinal beam moves to the appropriate height, the cylinder 53 is started, the cylinder 53 pushes the driving column 35 to slide to the limiting groove 61, the re-rotation of the connecting column 34 is limited through the limiting teeth 62, and the sliding of the connecting column 34 will squeeze the driving rod 51 to move to the driving rod 33, then the reversing cone 52 on the surface of the driving rod 51 is in contact with the clamping shaft 55, the driving rod 33 is driven by the motor 32 again to drive the fixed block 31 to rotate, and then the longitudinal beam rotates.

[0038] The above embodiments are only used to illustrate the technical method of the utility model and not to limit it, although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical method of the utility model.
