In order to ensure the arrangement of the second motor 21 and the simultaneous movement of the two push plates 27, a dual-output-shaft motor is selected for driving the worm 25 to rotate by the second motor 21, each output shaft 23 of the second motor 21 is connected with the worm 25 through a coupler 22, so that the worm 25 drives the worm wheel 24, and the worm wheel 24 drives the second crank-slider mechanism 26 through a turbine shaft, so that the push plates 27 reciprocate. The turnover mechanism comprises a turnover plate 31, a torsion spring 32, a longitudinal limit plate 33, a limit bearing 34 and a limit spring 35, wherein the turnover plate 31 is L-shaped, and the longitudinal limit plate 33 is connected with one end (the upper end of a shorter section) of the turnover plate 31 through the limit spring 35. The side face (the side face of the longer section) of the turnover plate 31 is provided with a turnover plate through groove 36, the rack 10 is provided with a guide rod 37 matched with the turnover plate through groove 36, and the turnover plate through groove 36 ensures that the turnover plate 31 can turn back and forth and in space.

Each time the push plate 27 pushes out the material, the pressure plate 28 presses down the limit plate bearing 34, so that the limit plate 33 descends to a certain height to push out the material 40. It should be noted that the height of the descent of the limit plate 33 is related to its own length and the longitudinal length of the presser plate 28.
When the turnover device works, the first motor 11 drives the driving shaft through belt transmission, the driving shaft and the driven shaft rotate in a matching mode so as to realize transportation of the conveying belts 20, and a space is reserved between the two conveying belts 20 so that the turnover plate 31 can be used for realizing turnover movement.
