The bedplate 2 is fixed and drives the supporting seat 1 to translate through the moving driving mechanism. The belt wheel 3 is driven to rotate by a rotation driving mechanism. Generally, the number of the belt pulleys 3 of the conveyor belt is two, and if several belt pulleys 3 are additionally arranged, the same number of supporting seats 1 are correspondingly arranged and still included in the concept solution of the present embodiment.

The hollow double-headed arrow in fig. 2 and 4 indicates the direction of translation of the support block 1.

In the embodiment, the bedplate 2 is provided with strip-shaped through holes 21, the number of the strip-shaped through holes 21 is equal to that of the supporting seats 1 and corresponds to that of the supporting seats one by one, and the strip-shaped through holes 21 are parallel to each other;

the movable driving mechanism is arranged below the bedplate 2, the central shafts 32 of the two belt wheels 3 respectively penetrate through the corresponding supporting seat 1 and the strip-shaped through hole 21 in sequence and then are connected with the movable driving mechanism in a transmission way, the central shaft 32 of at least one belt wheel 3 is connected with the rotary driving mechanism in a transmission way, and the two sealing rings 11 are respectively sleeved on the corresponding central shafts 32. The rotation driving mechanism is a motor. The motor is drivingly connected to the central shaft 32. When the movable driving mechanism is arranged below the bedplate 2, the medicine bottle and the movable driving mechanism can be prevented from forming cross contamination, and the sanitary and safe filling of the medicine bottle can be ensured.

Can inject two supporting seat 1 through bar through-hole 21 and all can only be to the back-and-forth movement of same straight line direction to can ensure that supporting seat 1 can coordinate the translation, the inconsistent condition of two supporting seat 1 moving direction can not appear.

In this embodiment, the rigid supporting member 12 is a sliding ring, each sliding ring and the sealing ring 11 are respectively embedded at the bottom end of the corresponding supporting seat 1, the bottom end of the sliding ring is in sliding contact with the platen 2, and each sealing ring 11 is sleeved outside the corresponding sliding ring. The sealing ring 11 is located outside the sliding ring, so that the sliding ring mainly bears the weight of the supporting seat 1, and the sealing ring 11 is prevented from being crushed by the supporting seat 1. The sliding ring slides on the bedplate 2 and is made of special materials, and the special materials have small frictional resistance and wear resistance.

In this embodiment, the bottom end of the supporting seat 1 is provided with a first annular groove 13 and a second annular groove 14, the second annular groove 14 is sleeved outside the first annular groove 13, and the first annular groove 13 is sleeved outside the corresponding central shaft 32; preferably, the protective sleeve 15 is further sleeved outside the central shaft 32, the protective sleeve 15 is fixedly connected with the bottom end of the support seat 1 to form a whole, and the first annular groove 13 is sleeved outside the protective sleeve 15. The protective sheath 15 protects the central shaft 32 from dust and impurities entering from this location and adhering to the central shaft 32.

The two sealing rings 11 are embedded in the corresponding second annular grooves 14, and the two sliding rings are embedded in the corresponding first annular grooves 13. First annular groove 13 has the fixed action to the slip ring, and is fixed comparatively stable, and the structure is comparatively simple, and supporting seat 1 passes through the slip ring and moves on platen 2, because the slip ring is littleer than supporting seat 1 frictional force and avoids supporting seat 1 directly to rub on platen 2 and move and produce the granule. The slip ring also can adopt other modes to fix in supporting seat 1 bottom, if can adopt welded mode, perhaps set up a draw-in groove and block the slip ring, as long as can fixed slip ring can. In contrast, the use of the first annular groove 13 for fixing and mounting the sliding ring is a simpler and more secure solution, and it is easier to control the height of the two supporting seats 1 to be the same. The second annular groove 14 is used for fixing and mounting the sealing ring 11.

A gap is arranged between the bottom end of the supporting seat 1 and the bedplate 2. The gap is formed when the height of the slip ring is greater than the depth of the first annular groove 13. The reference sign a in fig. 1 indicates this gap, and the platen 2 is not shown in fig. 1. Preferably, the gap is 0.3mm to 1 mm. It is further preferred that the clearance is 0.5mm, which means that the height of the slip ring is 0.5mm greater than the depth of the first annular groove 13. The support base 1 is directly arranged on the bedplate 2 through a rigid support 12, and a flexible support mode is not adopted, so that the height of the support base 1 is controllable.

The clearance is formed by the slide ring, and the distance of the clearance is not easily changed, and the seal ring 11 can be in a better sealing state. The situation that the sealing ring 11 is not sealed in place or the sealing ring 11 is abraded seriously due to the small gap can not occur.
