[0052] like Figure 6 As shown, the medicine hopper 1-4 includes a bottom plate 1-4a and baffles 1-4b arranged on both sides of the bottom plate 1-4a. The bottom plate 1-4a extends obliquely downward from the second vibrating corrugated plate 1-3 to the bottom of the negative pressure roller 2-1, and an arc-shaped avoidance groove 1-4c is formed on one end of the baffle 1-4b facing the negative pressure roller 2-1.

[0053] In order to improve the accuracy of counting filling, Fig.11 and Fig.12 As shown, a combing plate 1-5 is provided on the upper side of the medicine hopper 1-4 facing the negative pressure roller 2-1, and a plurality of combing holes 1-5a corresponding to the multiple rows of pill suction holes 2-1h are provided on the combing plate 1-5. The combing holes 1-5a can allow a pill 7 adsorbed on the negative pressure roller 2-1 to pass through to brush off the adhered pills adsorbed on the negative pressure roller 2-1, and the adhered pills are scraped off into the medicine hopper 1-4, ensuring that one pill 7 is adsorbed in each pill suction hole 2-1h on the negative pressure roller 2-1, thereby ensuring the accuracy of the pill suction counting.

[0054] The supporting mechanism comprises two supporting assemblies 2-2 arranged on both axial sides of the negative pressure roller 2-1, and the negative pressure joint 2-1d and the supporting part 2-1e are rotatably supported on the two supporting assemblies 2-2 respectively.

[0055] like Figure 7 and Figure 8 As shown, the support assembly 2-2 includes a support plate 2-2a and a plurality of support bearings 2-2b arranged on the support plate 2-2a, and the negative pressure joint 2-1d / support portion 2-1e is supported between the plurality of support bearings 2-2b.

[0056] In order to improve the stability of the structure, a first sliding groove 2-1f matching the four support bearings 2-2b is provided on the negative pressure joint 2-1d, and a second sliding groove 2-1g matching the four support bearings 2-2b is provided on the support part 2-1e. When the negative pressure roller 2-1 rotates, the negative pressure joint 2-1d and the support part 2-1e roll in the first sliding groove 2-1f and the second sliding groove 2-1g respectively.

[0057] The driving mechanism 2-3 includes a driving motor 2-3a, a driving gear 2-3b arranged at the power output end of the driving motor 2-3a, and a driven gear 2-3c arranged on the first end cover 2-1b. The driven gear 2-3c is meshed with the driving gear 2-3b. The driving motor 2-3a rotates to drive the driving gear 2-3b to rotate, and further drives the driven gear 2-3c to rotate, thereby driving the negative pressure roller 2-1 to rotate, so that the negative pressure roller 2-1 rotates to the pill suction position and the filling position in turn to complete the pill suction and filling.

[0058] The filling device 3 is used to fill the pellets adsorbed on the negative pressure roller 2-1 into the packaging bottle 6, such as Fig. 9 and Fig.10 As shown, it includes a filling funnel mechanism arranged below the negative pressure roller 2-1 and a brush plate 3-2 arranged between the filling funnel mechanism and the negative pressure roller 2-1, the upper end of the brush plate 3-2 is close to the negative pressure roller 2-1 and there is a gap between the negative pressure roller 2-1, and the lower end of the brush plate 3-2 extends to the feed port of the filling funnel mechanism. The filling funnel mechanism includes a plurality of filling funnels 3-3 arranged at intervals along the axial direction of the negative pressure roller 2-1, and each filling funnel 3-3 corresponds to at least one row of pill suction holes 2-1h.

[0059] Among them, the gap between the end of the brush plate 3-2 close to the medicine hopper 1-4 and the negative pressure roller 2-1 is smaller than the height of the pills 7 protruding from the surface of the negative pressure roller 2-1. In this way, when the negative pressure roller 2-1 that adsorbs the pills 7 rotates to the position of the brush plate 3-2, the brush plate 3-2 can brush off the adsorbed pills 7.

[0060] In this example, each row of pill suction holes 2-1h includes 50 pill suction holes 2-1h, each filling funnel 3-3 corresponds to two rows of pill suction holes 2-1h, and each filling funnel 3-3 corresponds to a packaging bottle 6 below, that is, one packaging bottle 6 can hold 100 pills.

[0061] In order to facilitate the installation of the filling funnel mechanism and the brush plate 3-2, the filling device 3 also includes a mounting plate 3-1, the brush plate 3-2 is fixed above the mounting plate 3-1, and the filling funnel mechanism is installed on the side of the mounting plate 3-1. Specifically, the brush plate 3-2 includes a guide plate 3-2a and side plates 3-2b arranged on both sides of the guide plate 3-2a in the length direction. The gap between the guide plate 3-2a and the negative pressure roller 2-1 gradually decreases from the filling funnel 3-3 to the medicine hopper 1-4. When the negative pressure roller 2-1 that absorbs the pellets 7 passes through the brush plate 3-2, the upper end of the guide plate 3-2a contacts the pellets 7 and brushes the pellets 7 off, and the pellets 7 roll down into the filling funnel 3-3 through the guide plate 3-2.

[0062] The bottle feeding device 4 is arranged below the filling device 3, and is used for inputting empty packaging bottles 6 and outputting filled packaging bottles 6. A conveyor belt mechanism commonly used in the prior art can be adopted. In order to facilitate filling, a bottle blocking mechanism 4-1 is provided at the filling position below the negative pressure roller 2-1. The bottle blocking mechanism 4-1 blocks multiple packaging bottles 6 corresponding to the negative pressure roller 2-1 below the filling device 3 to wait for filling.

[0063] In order to improve the filling accuracy, a detection device 5 is also provided on the side wall of the negative pressure roller 2-1, which is used to detect the position of the leaked pills on the negative pressure roller 2-1. For example, multiple monitoring cameras can be arranged along the axial direction of the negative pressure roller 2-1 to take pictures and monitor the negative pressure roller 2-1, and transmit the monitoring data to the control unit. The control unit determines the packaging bottle 6 corresponding to the position of the leaked pills and removes it by the rejection device in the subsequent process.

[0064] The working principle of the utility model is:

[0065] The pellets in the hopper 1-1 are transported to the medicine hopper 1-4 through the first vibrating corrugated plate 1-2 and the second vibrating corrugated plate 1-3, and the negative pressure roller 2-1 rotates clockwise. A group of packaging bottles 6 are blocked by the bottle blocking mechanism 4-1 under the negative pressure roller 2-1, and the pill suction holes 2-1h on the surface of the cylinder 2-1a absorb the pellets 7 in turn and rotate in the direction of the brush plate 3-2. When the absorbed pellets 7 move to the position of the brush plate 3-2, the brush plate 3-2 brushes the pellets 7 into the filling funnel 3-3, completing the filling of multiple packaging bottles 6. The next group of empty packaging bottles 6 are blocked under the negative pressure roller 2-1, waiting for the next filling cycle.

[0066] In summary, the filling device can improve filling efficiency, operate stably, ensure filling accuracy, and increase the service life of the equipment.
