when the toothpick box 5 does not reach the lower part of the turnover barrel 61 or does not start moving, the quantitative motor 76 and the turnover motor 68 are started, the turnover barrel 61 in fig. 1 is turned clockwise by 90 degrees to reach the horizontal position of the axis, the quantitative plate 73 completely enters the storage groove 731, the gap is completely opened, the action is completed quickly, so that the toothpicks cannot tilt, the toothpicks which are pre-placed in the hopper 71 pass through the gap to fill the quantitative box 72, the filling can be controlled by time, after the time is up, the quantitative motor 76 is controlled to rotate reversely, the gap is completely blocked, the quantitative plate 73 enters the installation groove 732, then the pushing cylinder 78 can be started, the pushing plate 77 is driven to push the toothpicks in the quantitative box to the turnover barrel 61 which is placed horizontally, and the length of the piston rod of the pushing cylinder 78 is longer than that of the quantitative box 72, so that the toothpicks in the quantitative box 72 can be completely pushed to the turnover barrel 61, then the pushing cylinder 78 is restored, and the turnover barrel 61 is turned 90 degrees anticlockwise to reach the axis vertical position;

when the toothpick box reaches the position below the turnover barrel 61 which is provided with toothpicks and located at the vertical position, the turnover motor 68, the driving motor 171 and the corresponding sensors form servo closed-loop control, so that the position is quite accurate, at the moment, the switch cylinder 64 can be started, the turnover barrel cover 65 is driven to move rightwards together, when the connecting block 654 is basically attached to the outer wall of the turnover barrel 61, the turnover cavity 611 is completely opened, at the moment, the distance between the bottom end of the turnover barrel 61 and the upper end of the toothpick box 5 is only 3-5mm, the turnover barrel cover 65 moves rapidly, toothpicks in the turnover cavity 611 almost synchronously fall into the toothpick box 5, and the toothpick box is slightly larger than the volume required by pre-loading toothpicks when being arranged, so that the situation that toothpicks cannot be loaded is avoided, and then the turnover barrel cover 65 resets;

meanwhile, the rotating motor 84 is started, the rotating device 8 rotates to the position below the cover device 9, the cover cylinder 91 is started to drive the rubber sucker 95 to move downwards, when the rubber sucker is basically attached to the toothpick box cover, the negative pressure pump is started to generate negative pressure, the toothpick box cover is sucked and then moves upwards, and the rubber sucker stops moving when the rubber sucker is separated from the flange of the rotating plate 81, at the moment, the toothpick box cover which is pre-placed in the cover storage box 82 slides downwards to the lower plane of the rotating plate 81 under the action of gravity, and the next toothpick box cover falls on the inclined plane of the rotating plate 81;

when a toothpick box with toothpicks moves to the position right below the cover device 9, the cover cylinder 91 is started, when the toothpick box is close to the upper surface of the toothpick box, the cover motor 93 is started, as the toothpick box 5 is in threaded connection with the cover of the toothpick box, and the contact part of the outer surface of the toothpick box 5 and the limiting block 4 is provided with vertical grains for limiting relative rotation, downward and rotary motion is generated under the combined action of the cover cylinder 91 and the cover motor 93, the cover motion is completed, whether the cover is completed or not is controlled by the displacement of the cover cylinder 91, when the cover is completed, the rubber suction disc is released, and the cover cylinder 91 is reset;

then the completely packaged toothpick box continues to move, the toothpick box falls into the guide groove 10 due to the effect of downward overturning and gravity at the end of the conveyor belt 3, if the toothpick box does not fall by itself, the toothpick box passively falls under the action of the baffle 18, the height of the toothpick box is not too high easily, a buffer material is arranged in the guide groove 10, then the toothpick box is vertically fallen on the electronic scale 13 under the limitation of the guide pipe 12, the control system makes a determination of qualification through weighing the weight of the toothpick box, and the rotating direction of the screening motor 145 is controlled to push the toothpick box out of the qualification outlet 15 or the defective product outlet 16;

so will accomplish once more automatic packaging, it is required to explain once more, the utility model provides a turning device 6, proportioning device 7, rotary device 8, lid device 9, sieving mechanism 14 and drive arrangement 17 can the autonomous working, but also can the synchronous working, but before toothpick box 5 reachs turning device 6 under, should accomplish pack into the toothpick and turn over inside 61 turnover barrel and turning device 6 upset to vertical state, in order to avoid taking place to interfere because the small distance of turnover barrel 61 bottom and toothpick box 5 upper end, before toothpick box that is equipped with the toothpick reachs under lid device 9, should accomplish rubber suction cup 95 inhale the lid action, and rotate rotary device 8 to safe position, save time when avoiding interfering, and simultaneously, the internal diameter of stand pipe 12 should not be greater than toothpick box too much, avoid taking place the deflection in its inside.
