At the same time, the pressure of the adjusting tube 20 on the adjusting rod 402 can increase the pressure of the clamping block 403 on the mother material 24, thereby improving the firmness of the fixation of the mother material 24 to be loaded.

[0034] In this embodiment, preferably, a support ring 6 is fixedly installed on the top of the slide 1, and the support tube 3 is rotatably installed in the support ring 6, so that the support tube 3 can be rotatably installed on the slide 1.

[0035] In this embodiment, preferably, a mounting plate 21 is fixedly installed on the left side of the top of the slide 1, and a multi-stage cylinder 22 is fixedly installed on the left side of the mounting plate 21. The output end of the multi-stage cylinder 22 passes through the mounting plate 21 and is fixedly installed with a push column 23, and the push column 23 is coaxially arranged with the two support tubes 3; the extension of the output end of the multi-stage cylinder 22 can push the push column 23 to move, and the push column 23 can push the mother material 24 to move after contacting with the mother material 24.

[0036] In this embodiment, preferably, the driving mechanism 2 includes a guide rail 201, a slide 202, a screw 203 and a second motor 204, the guide rail 201 is arranged at the bottom end of the slide 1, the slide 202 is slidably installed inside the guide rail 201, the slide 1 is fixedly installed on the slide 202, the top wall of the slide 202 is fixedly connected to the slide 1, the guide rail 201 is rotatably installed with a screw 203, the screw 203 passes through the slide 202, and the screw 203 is threadedly connected to the slide 202, the second motor 204 is fixedly installed at one end of the guide rail 201, and the output end of the second motor 204 is fixedly connected to the screw 203; the screw 203 can be driven to rotate by the second motor 204, and when the screw 203 rotates, it can drive the slide 202 to move, thereby driving the slide 1 to move.

[0037] Working principle: when feeding, the slide 1 is driven by the driving mechanism 2 to move so that the base material 24 moves into the atomizing chamber, and the third gear 11 is driven to rotate by the first motor 10, thereby driving the first gear 5 on the right side to rotate through the second gear 8, so that the support tube 3 on the right side drives the base material 24 inside to rotate, and cooperates with the plasma gun in the atomizing chamber to melt the end face of the base material 24 to form a molten liquid film, so that the liquid film is thrown out and broken into droplets, and these droplets are then atomized and solidified into spherical powder in an inert atmosphere, thereby realizing atomization powder making. As the base material 24 is consumed, after the support tube 3 stops rotating, the base material 24 can be pushed to the right by the multi-stage cylinder 22 in cooperation with the push rod 23, so that the base material 24 continues to extend into the atomizing chamber;

[0038] By setting the torsion spring 407, when the mother material 24 extends into the interior of the support tube 3, the elastic force of the torsion spring 407 causes the clamping block 403 to press against the outer peripheral wall of the mother material 24 to fix the mother material 24. When the support tube 3 rotates, under the action of centrifugal force, the counterweight block 404 is subjected to the centrifugal force outward, which is transmitted through the adjustment rod 402, so that the pressure of the clamping block 403 on the mother material 24 increases. The faster the rotation speed of the support tube 3, the greater the pressure of the clamping block 403 on the mother material 24, thereby ensuring the firmness of the fixation of the mother material 24.

[0039] When adding a new mother material 24, the mother material 24 is extended into the supporting tube 3 on the left, and the push rod 23 is pushed to the right by the multi-stage cylinder 22, so that the mother material 24 on the left moves to contact the end face of the mother material 24 on the right, and then the adjusting tube 20 is driven to move to the left by the hydraulic cylinder 18, so that the inclined surface 2001 of the adjusting tube 20 contacts the inner wall of the adjusting rod 402, thereby squeezing and locking the adjusting rod 402, so that the adjusting rod 402 and the supporting tube 3 are locked, so that the supporting tube 3 cannot rotate, and the pressure of the adjusting tube 20 on the adjusting rod 402 can increase the pressure of the clamping block 403 on the mother material 24, thereby improving the firmness of the fixing of the mother material 24, and when the connecting frame 19 moves to the left, the driving ring 25 drives the connecting tube 14 to move to the left, so that the first meshing disk 15 moves to the left, thereby the first meshing disk 15 and the second meshing disk 16 is separated, so that when the support cylinder 3 on the right side rotates, it is unable to drive the support cylinder 3 on the left side to rotate through the transmission assembly, and then the support cylinder 3 on the right side is driven to rotate at a high speed, so that the mother material 24 on the right side rotates at a high speed, while the mother material 24 on the left side remains stationary, so that the end faces of the two mother materials 24 are heated by friction and gradually melt and combine, and then the mother material 24 on the right side stops rotating, and the output end of the hydraulic cylinder 18 is controlled to contract to release the lock of the support cylinder 3 on the left side. At the same time, the first meshing disk 15 and the second meshing disk 16 of the transmission assembly are re-engaged, and the driving assembly drives the two support cylinders 3 to rotate synchronously through the transmission assembly, so that the two mother materials 24 rotate synchronously, and while the mother material 24 on the right side rotates at a high speed to atomize and powder, the contact surfaces of the two mother materials 24 gradually cool and fuse into shape, and this cycle repeats. When one mother material 24 is consumed, a new mother material 24 can be added from the left side.

[0040] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
