[0024] The lifting feeding mechanism 5 includes a driving cylinder 51 and a contact pad 52. A driving cylinder 51 is provided on the outer wall of the top end of the support bottom plate 1 directly below the storage bucket 3. The output end of the driving cylinder 51 is connected to the outer wall of the bottom end of the contact pad 52. The contact pad 52 is slidably installed inside the storage bucket 3. An outlet 53 is opened on the outer wall of the side of the storage bucket 3 at the top end. A conveying groove 54 is provided on the outer wall of the side of the storage bucket 3 at the outlet 53.

When the driving cylinder 51 is started, its extending end will automatically extend to drive the contact pad 52 to slide inside the storage bucket 3. When the contact pad 52 moves upward, it will automatically drive the steel ball raw materials inside the bucket to move upward. When the steel balls move to the outlet 53, they will fall into the inside of the conveying groove 54 in sequence. Then, through the diversion of the conveying groove 54, they will automatically fall into the inside of the guide pipe 55.

When the drive motor 61 is turned on, it will automatically drive the limit shaft 62 to rotate, and then the limit shaft 62 will automatically drive the contact plate 63 to rotate. When the contact plate 63 contacts the contact rod 64 with the contact groove 66 inside the special-shaped block 65 during the rotation process, it will automatically push the special-shaped block 65 to rotate. When the special-shaped block 65 rotates, it will automatically drive the support shaft 6 7 rotates and then drives the transmission block 68 to rotate. The setting of the abutting installation cylinder 69 here plays a role of limiting support for the rotation of the transmission block 68. It is noted here that the side outer wall of the transmission block 68 is provided with four notches. When the above-mentioned material guide tube 55 stores materials normally, the steel ball at the bottom end thereof will abut against the top outer wall of the transmission block 68 or just fall into the notch outside the transmission block 68. Then, the rotation of the transmission block 68 will cause the notch on its side to be in a rotating state synchronously, so that the steel ball is guided to the specified position through the guide groove 610, so as to achieve the effect of feeding materials one by one.

[0026] When the utility model is in use and it is necessary to add steel ball raw materials into the storage barrel 3, only the sealing cover 42 needs to be rotated until the threaded ring 43 completely disengages from the inside of the threaded groove 44. During installation, only the sealing cover 42 needs to be adjusted to a proper position and then the threaded ring 43 can be screwed to the bottom end of the threaded groove 44 to complete the installation. The positioning installation plate 41 here plays an auxiliary supporting effect on the storage barrel 3; when it is necessary to eject the steel ball raw materials inside the storage barrel 3, first, the driving cylinder 51 needs to be started. After the driving cylinder 51 is started, its extending end will automatically extend to drive the abutting pad 52 to slide inside the storage barrel 3. When the abutting pad 52 moves upward, it will automatically drive the steel ball raw materials inside the barrel to move upward. When the steel balls move to the discharge port 53, they will fall into the inside of the conveying groove 54 in sequence. Then, through the diversion of the conveying groove 54, they will automatically fall into the inside of the guide pipe 55. At this time, the steel balls are stacked on top of each other in the guide pipe 55; when it is necessary to control the output of the steel balls one by one, first, the driving motor 61 needs to be started. After the driving motor 61 is started, it will automatically drive the limiting shaft 62 to rotate. Then, when the limiting shaft 62 rotates, it will automatically drive the abutting plate 63 to rotate. When the abutting rod 64 abuts against the abutting groove 66 inside the special-shaped block 65 during the rotation of the abutting plate 63, it will automatically push the special-shaped block 65 to rotate; when the special-shaped block 65 rotates, it will automatically drive the support shaft 67 to rotate and then drive the transmission block 68 to rotate. The setting of the abutting installation cylinder 69 here plays a limiting and supporting effect on the rotation of the transmission block 68. It should be noted here that there are four notches on the outer side wall of the transmission block 68. When the guide pipe 55 stores materials normally, the steel balls at its bottom end will abut against the outer wall of the top end of the transmission block 68 or just fall into the notches outside the transmission block 68. Then, with the rotation of the transmission block 68, the notches on its side will be in a rotating state synchronously, so as to convey the steel balls to the designated position through the guidance of the guide groove 610, thereby achieving the effect of feeding one by one.
