In the invention:
the channel tube 2 is used for stacking pills 6 to be dispensed, and the pills 6 are stacked in a single row in the inner cavity of the channel tube 2; the limiting components 3 are used for controlling the number of pills falling down once in the inner cavity of the channel tube 2, wherein the position of each limiting component 3 corresponds to the position between two adjacent pills 6 in the channel tube 2, so that when different limiting components 32 are in limiting positions, the number of pills 6 falling down once in the channel tube 3 is different, for example, when the channel tube 3 is filled with pills 6, the pills 6 are counted from bottom to top, starting from the two pills at the bottom, the position between every two pills corresponds to one limiting component 3, when the number of pills to be discharged each time is determined, the corresponding limiting components 32 are adjusted to the limiting positions, for example, when three pills need to fall down each time, the limiting components 32 between the third pill counted from bottom to top and the fourth pill are adjusted to the limiting positions (see fig. 3), so that three pills can fall down each time;
it should be noted that, in the initial state, each limiting member 32 is not in a limiting gear position, and referring to fig. 5, each limiting member 32 is in the 12 o' clock direction shown in fig. 5;
the working principle of the embodiment is as follows:
firstly, a plurality of pills 6 are loaded in a leakage hopper 7 in advance;
subsequently, according to the number of going out the medicine at every turn, adjust the corresponding locating part 32 of each quantitative unloading subassembly, make it be in spacing gear (simultaneously, other locating part 32 all are not in spacing gear this moment), the adjustment process is as follows: poking the corresponding poking piece 35 with force by hand or tool through the first arc-shaped groove 12 of the housing 1 to rotate the poking piece 35, the rotation of the poking piece 35 will drive the annular sleeve 31 and the limit rod 32, the first spring 33 and the mark plate 34 fixed with the annular sleeve to rotate together until the mark plate 34 rotates to correspond to the window hole 11 of the housing 1, and the poking of the poking piece 35 is stopped, at this time, the number mark on the mark plate 34 can be seen from the outer side of the window hole 11, and at the same time, the limit piece 32 on the opposite side of the mark plate 34 just corresponds to the pressing block 41 and is positioned on the inner side of the pressing block 41, see fig. 3 and fig. 6; for example, when nine pills need to be discharged each time, the third limiting members 32 counted from bottom to top of the three quantitative blanking assemblies can be adjusted to limiting gears, as shown in fig. 1 and fig. 2, so that three pills can fall in a single channel tube 2 each time, and nine pills can fall in total in the three channel tubes 2; of course, the ninth limiting member 32 of one of the quantitative blanking assemblies can be adjusted to the limiting gear from bottom to top without adjusting the limiting members 32 of the other two quantitative blanking assemblies, so that nine pills can fall down each time; if the number of pills required to fall each time is more than ten, adjustment can be performed among the three quantitative blanking assemblies, and after the limiting pieces 32 are adjusted, the number of pills falling from the three channel pipes 2 is added to be equal to the preset number;
then, the motor 81 and the belt conveyor 9 are started simultaneously, the motor 81 drives the cams 82 to synchronously rotate after being started, the cams 82 intermittently contact the outer surface of the pressing block 41 when rotating, and the pressing block 41 can be driven to move to a limit position close to the channel tube 2 along the radial direction of the shell 1 every time of contact, as shown in fig. 9 and 10, in the process, the pressing block 41 pushes the limiting part 32 to move, and the bushing 5 also moves along with the pressing block 41, so that the needle body 321 of the limiting part 32 is inserted into the inner cavity of the channel tube 2, and the leak hole 51 of the bushing 5 moves to the position right below the channel tube 2, so that the pills above the needle body 321 are blocked by the limiting part 321 and cannot fall down, and the pills below the needle body 321 fall down from the leak hole 51, so that a single fixed number of pills are discharged, for example, each time each rotation of the cams 82 in the drawing, each channel tube 2 falls down three pills, and the total number of pills falling down by the three channel tubes 2 is nine; meanwhile, because the lower belt conveyor 9 is in continuous motion, pills falling each time can fall on different positions on the belt conveyor 9; in the rotating process of the cam 82, when the cam is separated from the pressing block 41 after contacting the pressing block 41 each time, the pressing block 41 returns to the initial position under the action of the second spring 42, meanwhile, the limiting member 32 also returns to the initial position under the action of the first spring 32, the needle body 321 is hidden in the second arc-shaped groove 21 again, the leakage plate 5 also returns to the initial position under the drive of the pressing block 41, and the leakage hole 51 and the opening at the bottom of the channel tube 2 are staggered again, namely, the state shown in fig. 1 and 2 is restored; therefore, the pills above the needle body 321 will fall and stack on the top of the nozzle plate 5, and part of the pills in the nozzle hopper 7 will enter the channel tubes 2; then, when the cam 92 rotates and then contacts the pressing block 41 again, the fixed number of pills fall down again in the channel tube 2;
that is, in short, each time the cams 82 rotate once, the pressing block 41 reciprocates, and a certain number of pills fall down in the channel tube 2. When the number of pills falling in a single time needs to be adjusted, the corresponding limiting parts 32 of each quantitative blanking assembly are adjusted to limiting gears, and meanwhile, other limiting parts 32 are not limited gears.
Wherein, can arrange a plurality of packing cartons on band conveyer 9, make it along with band conveyer 9 removes, and ensure the interval of each packing carton, make the pellet that falls in each time passageway pipe 2 can fall into different packing cartons respectively.
The invention realizes the quantitative distribution of the spherical pills, and the adjustment of different limiting parts 32 can also adjust the quantity of the pills which are quantitatively distributed each time, namely, the switching of different distribution quantities can be realized on a single device.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
