[0038] Two groups of positioning rods 209 are provided on the surface of the opening 208 of the feeding tray 202, and each group of positioning rods 209 is provided on the surface of the feeding tray 202.

Only the positioning rod 209 at the lower right is fixedly installed with the extension block 207, so that when the material rotates under the operation of the turntable 205, when the material moves obliquely upward, the material contacts the extension block 207 of the positioning rod 209, so that the material can move obliquely upward under the action of the extension block 207, and at the same time, the four positioning rods 209 can position the material, so as to ensure that the material enters the collecting box 2010 in the same direction, so that the material can be arranged neatly.

[0040] The guide rod of the clamping electric push rod 402 is movably installed with four movable rods 403, and the two movable rods 403 are movably installed with a clamping plate 404. At the same time, an anti-slip pad is provided on the top of the clamping plate 404, so that the guide rod of the clamping electric push rod 402 can be moved by the operation of the clamping electric push rod 402 inside the installation box 401, so that the movable rod 403 can be rotated, and then the two clamping plates 404 can be rotated, so that the material at the discharge port 2011 of the collecting box 2010 can be clamped, so that the feeding of the material can be facilitated.

[0041] Working principle of this embodiment: When using the automatic device for material feeding, firstly according to Figure 1-7 , the staff puts the material into the positioning device 2 above the main body 1 of the material feeding device, so that the material is put into the feeding tray 202 above the fixed frame 201, so that the material can be set on the surface of the turntable 205, so that part of the material moves downward under the action of gravity due to the inclined setting of the turntable 205, and is set at the bottom of the feeding tray 202. Then, the positioning motor 204 connected to the mounting frame 203 is started, and the turntable 205 can be rotated by the positioning motor 204, so that the turntable 205 can drive the material on the surface to move, so that the material can be stuck in the inside of two adjacent blocks 206, and other materials not set in the inside of the two blocks 206 move downward under the action of gravity, and the above work is repeated until it is set in the inside of the two blocks 206.

[0042] At the same time, according to Figure 1-4 and Figure 6 The materials inside the two blocks 206 will come into contact with the extension block 207 at the bottom, so that the running trajectory of the materials can be changed through the extension block 207. At the same time, the top of the materials is just led out from the opening 208 of the feeding tray 202, so that the four positioning rods 209 can position the materials, so that the materials are neatly arranged on the surface of the collecting box 2010.

[0043] Next, according to Figure 1-2 and Figure 8, by starting the moving device 3 on the right side of the device body 1 to work, the second electric push rod 307 above the movable plate 306 can move the installation box 401 provided with the clamping device 4 upward, and at the same time, through the drive motor 305 above the movable block 302, the movable plate 306 is rotated under the action of the drive motor 305, so that the clamping device 4 can face the discharge port 2011 of the collection box 2010, finally, through the operation of the first electric push rod 301, the slider 303 under the movable block 302 moves on the surface of the guide rail 304, so that the clamping device 4 can approach the surface of the collection box 2010.

[0044] Then, according to Figure 1-2 and Figure 8-9 When the clamping plate 404 of the clamping device 4 is arranged inside the discharge port 2011, the guide rod of the clamping electric push rod 402 is moved by the operation of the clamping electric push rod 402 inside the installation box 401, so that the movable rod 403 can be rotated, and then the two clamping plates 404 can be rotated, so that the material at the discharge port 2011 of the collection box 2010 can be clamped, and under the action of the moving device 3, the clamping device 4 with the material is moved, so that the material can be placed on the surface of the workbench, and after the material processing is completed, the processed material can be removed by the cooperation of the clamping device 4 and the moving device 3. Finally, repeat the above work to complete the processing of multiple groups of materials, so that the automatic device for feeding multiple groups of materials can be used.
