[0044] The upper feeding device 81 includes a feed stop device 32 and a feed anti-retraction device 80. The structure of the feed stop device 32 is the same as that of the lower stop device 31 and is installed on the frame 1; the feed anti-retraction device 80 is installed on the frame 1 and is arranged opposite to the feed stop device 32. The feed anti-retraction device 80 is also located at the top of the descending device, and is used to push the material tray 91 onto the descending device.

The feed stop spring 815 is located between the feed stop seat 813 and the feed stop block 814, and is used to keep one end of the feed stop block 814 raised State, when the material tray 91 enters, the feed stop block 814 descends under the pressure of the lower end of the material tray 91 until the material tray 91 is completely moved to one end of the feed stop block 814, and then the feed stop block 814 rises under the action of the feed stop spring 815 and rests on one end of the material tray 91, and then the feed stop cylinder 812 is started, and the feed stop cylinder 812 drives the material tray 91 to enter the descending moving device of the descending device through the feed stop block 814, and rests on the feed stopping device 32, and then the material tray 91 follows the descending moving device and descends to the lower discharging device 82 under the action of the descending belt device.

[0045] The upper discharging device (22) adopts a magnetic drive conveying line or a roller conveying line.

[0046] The lower discharge device 82 includes a lower discharge rack 821, a magnetically driven discharge conveyor line 822, and discharge conveyor rollers 823. The lower discharge rack 821 is fixed to the bottom of the frame 1, and the magnetically driven discharge conveyor line 822 is mounted on the lower discharge rack 821. Ten discharge conveyor rollers 823 are symmetrically arranged on both sides of one end of the lower discharge rack 821 in an array, with five discharge conveyor rollers 823 on each side of the lower discharge rack 821. Lower guide rods 825 are also symmetrically mounted on the top of the lower discharge rack 821 to guide the material tray 91.

[0047] The bottom of the material tray 91 is provided with a magnet, which can be driven by magnetic force.

[0048] During operation, the material tray 91 filled with materials enters the lower feeding device 21 through the feeding conveyor line, and the lower magnetic drive conveyor line 211 pushes the material tray 91 to move to the lower stop device 31, and the lifting moving device 7 rises under the drive of the lifting belt device, and the lifting roller 72 passes through the lower conveying roller 212. The two sides of the material tray 91 are against the lifting roller 72 and rise with the lifting roller 72, and then enter between the lifting stop rods 41. The two ends of the material tray 91 are blocked by the lifting stop rods 41, and the two sides of the material tray 91 are blocked by the lifting moving plate 71, so that the material tray 91 will not separate from the lifting belt device. When the material tray 91 rises to the upper shifting device 5 at the top of the lifting belt device, the upper driving device drives the upper moving seat 55 to push the material tray 91 to move upward to the discharging device 22, and then the material tray 91 passes through the upper discharging device 22 into the discharging conveyor line, and then production is carried out. After production is completed, the empty material tray 91 or the material tray 91 loaded with products enters the upper feeding device 81 and the descending moving device of the descending device through the conveyor line. The feed stop device 80 pushes the material tray 91 to the feed blocking device 32 to prevent the material tray 91 from not fully entering the descending moving device. Then the material tray 91 follows the descending device to enter the lower magnetic drive conveyor line 211 of the lower discharging device 82. The lower magnetic drive conveyor line 211 drives the material tray 91 to move toward the external conveyor line, completing the ascending feeding and descending returning of the material tray 91, and realizing the circulation of the material tray 91.
