The support frame 1 is fixedly connected to the material changing rack 342, and the material changing rack 342 is slidably connected to the material changing plate 341. The bottom end of the material changing plate 341 is fixedly connected to a fourth connecting rod 344, and one end of the fourth connecting rod 344 is fixedly connected to the fourth telescopic cylinder 343.

[0068] When the material in the first material tray 222 or the second material tray 224 is used up, the fourth telescopic cylinder 343 is started, so that the fourth telescopic cylinder 343 drives the fourth connecting rod 344 to move downward, and the fourth connecting rod 344 drives the material changing plate 341 to slide downward in the material changing rack 342, and then the first material tray 222 or the second material tray 224 that has run out of material is taken out, and then the fourth telescopic cylinder 343 is started again to push the material changing plate 341 upward to reset through the fourth connecting rod 344.

[0069] In a specific embodiment, the volume of the first material tray 222 is preset to be smaller than that of the second material tray 224, that is, the area of ​​the first material tray 222 is smaller than that of the second material tray 224, the volume of the first material plate 3325 is the same as that of the first material tray 222, and the volume of the second material tray 224 is the same as that of the second material plate 3325, and the spacing between the multiple material columns on the first material plate 3325 and the spacing between the multiple second material columns 3323 on the second material plate 3325 are a, and the through holes are arranged between the multiple second material columns 3323, the spacing between the multiple through holes is also a, and the spacing between the through holes and the second material columns 3323 is 0.5a;

[0070] When it is necessary to take material from the first material tray 222, the started first telescopic cylinder 3312 drives the sliding frame and the fixed frame 3321 to move toward the first telescopic cylinder 3312, so that the sliding plate 3311 drives the first rack 3211 to mesh and rotate with the first gear 3221, so that the first gear 3221 drives the third gear 3231 to move through the first rotating rod 3222, so that the third rack 3233 drives the first transport clamp 312 to slide on the material changing plate 341 in the first sliding frame 311, and then the first transport clamp 312 transports the first material tray 222 to the material changing plate 341, and the third telescopic cylinder 3316 is started, so that the third telescopic cylinder 3316 drives the first material taking plate 3325 to move on the second material taking plate 3325 through the third connecting rod 3317. The first material picking column 3322 of the first material picking plate 3325 is made to correspond to the through hole of the second material picking plate 3325, and the volume of the first material picking plate 3325 is the same as the first material tray 222. At the same time, the second telescopic cylinder 3314 is started, so that the second telescopic cylinder 3314 drives the second material picking column 3323 of the second material picking plate 3325 to move downward through the second connecting rod 3315, so that the second material picking column 3323 can only move downward against the first material tray 222 to slide upward in the fixing frame 3321, so that the second material picking plate 3325 moves upward, and the first material picking column 3322 is inserted into the through hole to pick up the first material tray 222 through the first electromagnet 3326, so as to obtain the milling cutter workpiece on the first material tray 222. Correspondingly, the spacing between the milling cutter workpieces corresponds to the through hole, which is a;

[0071] When taking materials from the second material tray 224, it is only necessary to start the second telescopic cylinder 3314 to drive the second material taking plate 3325 in the fixed frame 3321 to move downward, so that the second material taking plate 3325 drives the second material taking column 3323 to move downward, and the second material taking column 3323 absorbs and takes materials from the second material tray 224 through the second electromagnet 3327, thereby obtaining the milling cutter workpiece on the second material tray 224. Correspondingly, the spacing between the milling cutter workpieces corresponds to the through hole, which is a; it can be seen from the spacing between the through hole and the second material taking column 3323 is 0.5a, so that the spacing between the material of the first material tray 222 and the material of the second material tray 224 is 0.5a.

[0072] It can be understood that, when picking up materials for the first time, the milling cutter workpiece is first obtained through the first picking column 3322. At this time, the milling cutter workpiece obtained for the first time is arranged at a spacing a, and then reset to the top of the second picking plate 3325, which does not affect the subsequent second picking up of materials; when picking up materials for the second time, the milling cutter workpiece is obtained through the second picking column 3323. Similarly, the milling cutter workpiece obtained for the second time is arranged at a spacing a. However, the spacing between the through hole (corresponding to the first picking column 3322) and the second picking column 3323 is 0.5a. In fact, the milling cutter workpieces obtained twice are arranged at a spacing of 0.5a, so that as many milling cutter workpieces as possible can be obtained within a limited space. That is to say, in the limited space of the picking plate 3325, the milling cutter workpieces can be more densely distributed through the spatial staggered setting. On this basis, through the setting of the above-mentioned gears and racks, plus the overlap of the first material picking plate 3325 and the second material picking plate 3325, it means that in the sliding direction of the sliding frame, the first material picking plate 3325 and the second material picking plate 3325 are overlapped, thereby reducing the overall width of the milling cutter workpiece loading device of the milling cutter welding machine, reducing the overall footprint, and reducing site costs, that is, achieving intensive material picking and reducing the space occupied by the device.
