In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0039] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0040] This embodiment provides an improved pill dispensing machine dispensing tray assembly, referring to Figures 1 to 6, which includes a loading tray 1. The loading tray 1 is in the shape of a disk, and a material protection barrel A11 is arranged along the circumference of the loading tray 1 to prevent the pills from rebounding and splashing into the external space when they fall into the loading tray 1, thereby reducing the loss of pills. A mounting through hole A13 is provided in the central part of the loading tray 1, and four positioning holes A14 are provided in a circular manner around the mounting through hole A13. The distance between the center of the positioning hole A14 and the axis of the loading tray 1 is L1. The mounting through hole A13 and the positioning hole A14 can subsequently provide installation space for other components to realize the relative movement between the loading tray 1 and other components. A material protection barrel B15 is arranged around the four positioning holes A14 away from the axis of the loading tray 1. The material protection barrel B15 cooperates with the material protection barrel A11 to limit the effective charging range of the pills in the rotating tray 1. The loading tray 1 is provided with four loading holes 12 in the middle area surrounded by the protecting tube A11 and the protecting tube B15. The four loading holes 12 are all of the same size and have the same spacing from each other. The center of each loading hole 12 is at a distance L2 from the axis of the loading tray 1. The four loading holes 12 are used to store pills, which can ensure that the stacking volume of the pills is consistent when loading.

[0041] The improved pill dispensing machine dispensing tray assembly also includes a dispensing tray 2, which is in the shape of a disk and has the same diameter as the loading tray 1. The upper surface of the dispensing tray 2 is in contact with the lower surface of the loading tray 1. A positioning frame 21 is fixed on the lower surface of the dispensing tray 2. The positioning frame 21 is also fixed on an external support structure that cannot be moved during operation. The positioning frame 21 is used to limit the position of the dispensing tray 2, and to limit its displacement and circumferential rotation. A mounting through hole B23 with the same diameter as the mounting through hole A13 is provided in the central part of the dispensing tray 2, and a placement groove 25 is provided around the mounting through hole B23 to provide installation space for the connecting piece that exceeds the bottom of the loading tray 1. A dispensing hole 22 is provided in the dispensing tray 2 at a length position L2 from the axis. The diameter of the dispensing hole 22 is slightly larger than the diameter of the loading hole 12, so that the pills in the loading hole 12 can fully fall into the dispensing hole 22. During the rotation of the loading tray 1 around the axis, at most only one of the loading holes 12 is connected to the discharge hole 22, so that the pills can fall. A receiving hopper 24 is arranged below the discharge hole 22, and a gap is left between the receiving hopper 24 and the discharge hole 22. The diameter of one end of the receiving hopper 24 close to the discharge tray 2 is slightly larger than the diameter of the discharge hole 22, and the diameter of the other end of the receiving hopper 24 is slightly smaller than the caliber of the filling container. The receiving hopper 24 is used to introduce the pills into the filling container during the canning process.

[0042] The improved pill dispensing machine material dispensing disc assembly further comprises a rotary transmission device 3. Figure 4The rotating transmission device 3 is cylindrical in shape, and its main body passes through the through space formed by the mounting through hole A13 and the mounting through hole B23. At the same time, the rotating transmission device 3 is connected to the loading tray 1 by bolts, so that the two components always maintain the same motion form when working.

[0043] The rotary transmission device 3 in this embodiment is composed of a pin shaft 31, a snap ring 32, a bolt 33, etc. The pin shaft 31 is a superimposed cylindrical shape in the axial direction, and the diameter of the bottom end thereof is larger and the same as the diameter of the mounting through hole A13, which can ensure that there will be no relative eccentricity and wear between the components during relative rotation; a snap groove 311 is provided at the bottom of the pin shaft 31 for keyway connection with the power device providing rotation, and the pin shaft 31 can transmit the force to rotate the rotary transmission device 3. The rotary transmission device 3 is provided with a snap ring 32 at one end of the top, and the snap ring 32 is sleeved on the outer periphery of the pin shaft 31 and fixed to the pin shaft 31 as a whole. A clamping cap 321 is provided on the top of the clamping ring 32 in a circular ring shape, and the inner diameter of the clamping cap 321 is the same as the diameter of one end of the top of the pin shaft 31; a clamping flange 322 is provided at the bottom of the clamping ring 32 in a circular ring shape, and a positioning hole B3221 is opened on the clamping flange 322, and the center length of the positioning hole B3221 from the axial center of the clamping flange 322 is L1, and it corresponds to the positioning hole A14 one by one, and the bolt 33 passes through the through channel formed by the positioning hole B3221 and the positioning hole A14 to fix the rotating transmission device 3 and the loading tray 1.

[0044] The improved pill dispensing machine material tray assembly also includes a fixed frame 4, a connecting frame 5 and a brush 6. In this embodiment, one end of the fixed frame 4 has a support base 42, which can stabilize its own position, and the other end is divergent in the horizontal direction, and five support arms 41 are extended outward, and the angle between two adjacent support arms 41 is 45 degrees. The support arms 41 are provided with positioning bolts B411 for connecting other components. The fixed frame 4 mainly provides support for other components, and the positioning frame 21 is fixed on the fixed frame 4. Two inserts 51 are provided on the upper part of the connecting frame 5. The inserts 51 are in the shape of elongated thin sheets, and a sliding groove B511 is opened along its length direction. The positioning bolt B411 can slide in the sliding groove B511. The lower part of the connecting frame 5 is provided with a groove-shaped member 52, and sliding grooves A521 are opened in the horizontal direction on the two side walls of the groove-shaped member 52, and the brush 6 can be inserted into the groove-shaped member 52. In this embodiment, two brushes 6 are provided, namely, brush A61 and brush B62. A positioning bolt A631 is provided on the brush handle 63, and the positioning bolt A631 can slide in the sliding groove A521. The brush A61 and the brush B62 are arranged along the radial direction of the charging tray 1. The brush head 64 of the brush 6 can be slightly bent, and the length of the brush head 64 is slightly greater than the shortest distance between the material protection tube A11 and the material protection tube B15. By adjusting the positional relationship between the connecting frame 5 and the support arm 41, the angle between the two brushes 6 can be changed. In this embodiment, the brush A61 and the brush B62 are separated by a support arm 41, and the angle between the two brushes 6 is designed to be 90 degrees. By adjusting the vertical position of the sliding groove B511, the height of the brush 6 can be adjusted, and the brush 6 can be made to contact the charging tray 1.

[0045] The improved pill dispensing machine material dispensing tray assembly further comprises a power source 7, the upper portion of which is provided with an extended rotating shaft 71, and the top of which is provided with a key 711 matching the card slot 311. When the rotating shaft 71 rotates, the rotary transmission device 3 and the loading tray 1 can be driven to rotate accordingly. The upper portion of the power source 7 is also provided with an extended electric push rod 72, and the working end of the electric push rod 72 can perform telescopic movement along its length direction.

[0046] The improved pill dispensing machine dispensing tray assembly also includes a baffle 8, the main part of which is placed in the gap between the discharge hole 22 and the receiving hopper 24, and is close to the lower surface of the discharge tray 2. The main structure of the baffle 8 is a thin disc, and can completely cover the discharge hole 22. The baffle 8 extends a force arm 81 along the diameter direction, and the resistance arm 81 is bent away from the discharge tray 2, and is L-shaped in the vertical direction. The bottom end of the force arm 81 is fixedly connected to the electric push rod 72, which can realize the automatic displacement of the baffle 8. When the discharge hole 22 coincides with the center of the loading hole 12, the electric push rod 72 automatically performs a telescopic movement, thereby driving the baffle 8 to automatically open, and the pills can fall smoothly into the canned container.

[0047] The reasons for filling differences can be roughly divided into the following points:

[0048] 1. During the filling process, the time for the pills to fall into the canning hole each time is too short, resulting in the canning hole not being fully filled, which leads to too large a difference in the packing density of the pills in the canning hole.

[0049] 2. During the canning process, the pills that pop out of the top of the canning hole are not cleaned manually in time, causing some pills that should have been cleaned away to be filled.

[0050] In addition, the pills that directly enter the filling container from the loading port have a long falling distance and may collide with the container, causing some pills to be damaged, thus affecting the quality of the pills in the filling container.

[0051] Reference Figure 1 to Figure 2 In this embodiment, before the power source 7 is turned on, the relative positions of the sliding groove B511 and the positioning bolt B411 are adjusted so that the brush 6 contacts the upper surface of the loading tray 1. Figure 3 At this time, the two brushes 6 divide the loading tray 1 into two areas a and b in the horizontal space. The area with a smaller coverage area is area a, which is the filling area, and the discharge hole 22 is fixedly set within the filling area; the other area is area b, which is the loading area, and the external lower hopper is fixed above the loading area. Continue to adjust the relative positions of the sliding groove A521 and the positioning bolt A631, so that the brush 6 is against the material protection barrel A11 and the material protection barrel B15 along the radial direction of the loading tray 1, and the sealing of the two areas is maintained to the greatest extent.

[0052] When the power source 7 is turned on, the rotating shaft 71 drives the pin shaft 31 to rotate, thereby driving the loading tray 1 to rotate. Since the position of the fixing frame 4 does not change during operation, the parts fixed to the fixing frame 4 will not change position either. Therefore, when the loading tray 1 rotates around the axis, the two areas a and b will not rotate around the axis relative to the entire pill distributor, but will always maintain a relatively fixed position.

[0053] In this embodiment, affected by the position of the external lower hopper and the blocking effect of the two brushes 6, after the pills fall from the lower hopper onto the loading tray 1, they will always be blocked in the loading area. At this time, the loading tray 1 rotates clockwise to drive the pills on its surface to roll. When the loading hole 12 is in the loading area, the pills automatically enter the loading hole 12 by gravity. The friction generated by the tiny collisions between the stacked pills and the pressure exerted by the upper pills can make the pills in the loading hole 12 continuously dense, thereby ensuring that the pills in the loading hole 12 have the same stacking density each time they are filled, reducing the difference in insufficient filling.

[0054] When the loading hole 12 enters the filling area through the brush A61, the pills that exceed the height of the loading hole 12 can be blocked in the loading area under the filtration of the brush A61, so that the volume of each filling is the volume of the loading hole 12, thereby avoiding the difference of excessive loading, and the soft brush 6 also minimizes the damage to the pills. During the working process, there are no extra pills on the surface of the filling area. When the loading hole 12 and the discharge hole 22 begin to form a through area, the pills gradually fall from the loading hole 12 into the discharge hole 22 and are held by the baffle 8. When the centers of the loading hole 12 and the discharge hole 22 completely overlap, all the pills fall completely into the discharge hole 22. At the same time, the electric push rod 72 drives the baffle plate 8 to automatically move, so that the baffle plate 8 is completely offset from the discharge hole 22, and the pills fall into the filling container through the loading hole 12, the discharge hole 22, and the receiving hopper 24 in sequence. In this embodiment, the height of the pills falling during filling is reduced, thereby reducing the potential energy of the pills and reducing the bumps and damages caused by the pills falling into the container.

[0055] When the loading hole 12 continues to rotate, the electric push rod 72 returns to its original position and drives the baffle 8 to cover the discharge hole 22 again. The electric push rod 72 automatically retracts and contracts again when the next loading hole 12 and the discharge hole 22 are connected, thereby achieving continuous filling. In this embodiment, the frequency of the electric push rod 72 automatically retracting and contracting once is 4 times the frequency of the loading plate 1 rotating one circle, thereby ensuring that the baffle 8 can automatically deflect each time the center of the loading hole 12 and the discharge hole 22 completely coincide.

[0056] When the discharge hole 12 re-enters the loading area through the brush B62, the loading hole 12 begins to be refilled with pills. At the same time, the enlarged loading area also allows the loading hole 12 to stay in the loading area for a longer time, so that the pills in the loading hole 12 are more compact, further avoiding filling differences and keeping the quality of each filling within a reasonable range of differences.

[0057] The utility model is easy to use. By controlling the position of the brush 6 on the charging tray 1, the area of ​​the charging area is adjusted, and the excess pills are automatically removed, so as to control the accumulation volume of the pills in the charging hole 12 during the charging process, and solve the disadvantage of the large difference in the dosage of the traditional dispensing device. At the same time, the utility model is easy to disassemble. The fixing frame 4, the connecting frame 5 and the brush 6 can be disassembled from each other, and the maintenance and replacement are simple, and the cost is low.
