Description

Technical Field

[0001] This invention relates to the technical field of filling, and in particular to the technical field of automatic quantitative filling devices for dry suspensions. Background Technology

[0002] Dry suspensions are a type of suspension. After being dispersed in water, they should meet the quality requirements of suspensions. The particles in the suspension should be evenly dispersed and should not settle rapidly. After settling, they should not form cakes and should be quickly redispersed after shaking. In addition to effectiveness and chemical stability (which mainly depends on the properties of the active ingredient), an ideal suspension should also (1) settle slowly and be redispersible after gentle shaking; (2) the size of the suspended particles should remain unchanged during long-term storage; and (3) be easy to pour. The above refers to the physical stability of suspensions. Dry suspensions have the characteristics of solid preparations (granules), such as being easy to carry, convenient to transport, and having good stability, as well as the advantages of liquid preparations (easy to take and suitable for patients with difficulty swallowing, such as children and the elderly). Dry suspensions are generally filled using a filling machine.

Side baffles are installed on the upper ends of both sides of the production line body, and two side baffles are provided. Fixed frames are installed on both sides of the production line body, and two fixed frames are provided.

It is equipped with a second mounting base, and a high-pressure pump is mounted on the upper end of the second mounting base. There are six high-pressure pumps. A water storage tank is mounted on the upper end of the high-pressure pump. A water inlet is mounted on the upper end of the water storage tank.

[0004] Existing patent CN116534314A discloses a dual-head granule filling device for preparing oseltamivir phosphate dry suspension. The device uses a drive assembly to rotate a horizontal plate, which allows an arc-shaped tray on a limiting baffle to clamp the packaging can and move it upward to separate it from the conveyor belt. This ensures that the conveyor belt does not affect the position of the current packaging can when it transports subsequent packaging cans forward, allowing all packaging cans to be filled before being transported forward, thus effectively reducing the probability of filling omissions. However, it cannot remove bottles with insufficient filling volume. Summary of the Invention

When the electric flip plate 16 is flipped to be parallel to the discharge conveyor belt 12, the side of the electric flip plate 16 near the defective product collection frame 15 is an arc-shaped surface.

[0027] Working process of this invention: The automatic quantitative filling device for dry suspension of the present invention, taking a device with four discharge pipes 70 as an example, mainly includes the following steps during operation: Bottle waiting process: The fourth telescopic stop 30 (i.e., the downstream telescopic stop 30) extends along the direction of movement of the feeding conveyor belt 11. The bottle moves along the feeding conveyor belt 11 and is blocked when it reaches the bottle-dispatching wheel 2. The bottle-dispatching wheel 2 rotates, and the downstream bottle enters the first slot 20 of the bottle-dispatching wheel 2. Then, driven by the bottle-dispatching wheel 2, it moves and eventually leaves the bottle-dispatching wheel 2, continuing to move along the feeding conveyor belt 11 until the bottle is blocked by the telescopic stop 30. Then the third telescopic stop 30 extends, and the next bottle enters the downstream of the bottle-dispatching wheel 2 under the drive of the bottle-dispatching wheel 2 until it is blocked by the third telescopic stop 30. This process is repeated twice, until each telescopic stop 30 blocks one bottle. Then the stop 30 resets, and the four bottles that were originally blocked by the telescopic stop 30 are in a waiting state.

[0028] Bottle weighing and filling process: The linear slide 51 drives the first servo motor 53, the connecting rod 54, and the bottle-shifting plate 55 to move together towards the feed conveyor belt 11. After moving a certain distance, the movement stops. Then, the first servo motor 52 drives the rotating shaft 53 to rotate at a small angle. The rotating shaft 53 drives the connecting rod 54 and the bottle-shifting plate 55 to move a small distance towards the baffle plate. At this time, there are 4 bottles in standby state, 4 bottles located on the 4 first weighing devices 41, and 4 bottles located directly below the 4 discharge pipes 70. The bottles, including four bottles located on four second weighing devices 42, are inserted into the second slots 56 of the bottle-moving plate 55, with each bottle corresponding to one second slot 56. Then, the linear slide 51 drives the first servo motor 53, the connecting rod 54, and the bottle-moving plate 55 to move away from the feeding conveyor belt 11 until the first servo motor 53 returns to its initial position. At this point, the four bottles that were originally in a standby state have moved to the four first weighing devices 41. The bottles, originally located directly below the four discharge pipes 70, are now positioned on the four second weighing devices 42. These bottles are then moved onto the discharge conveyor belt 12. The transmission mechanism drives the rotating shaft 61 to rotate a small angle, which in turn drives the connecting arm 62 to rotate. The connecting arm 62 then moves the mounting rod 63 and the positioning plate 64 towards the baffle plate, until the third slot 65 on the positioning plate 64 and the baffle plate together clamp the bottles on the bottle-laying platform. The third slot 65 corresponds one-to-one with the bottles on the square bottle platform. Then, the filling mechanism 7 fills the four bottles below the discharge pipe 70. During the filling process, the four new bottles enter the standby state through the bottle standby process. After filling is completed, the first servo motor 53 drives the connecting rod 54 and the bottle moving plate 55 to reset. The transmission mechanism drives the connecting arm 62, the mounting rod 63 and the positioning plate 64 to reset through the rotating shaft 61. The first weighing device 41 weighs the empty bottles and the second weighing device 42 weighs the filled bottles. The weighing information is fed back to the control device.

[0029] Rejection process: Bottles moved onto the discharge conveyor belt 12 move along the conveyor belt 12. If the weighing information of a bottle indicates that the weight of the filling material is not up to standard, the control device calculates the time it takes for the bottle to reach the electric flip plate 16 based on the running speed of the discharge conveyor belt 12 and the position and time of the bottle's movement on the discharge conveyor belt 12. When the bottle approaches the electric flip plate 16, the electric flip plate 16 closes down, and the bottle is guided into the defective product collection box 15. Then the electric flip plate 16 resets. It should be noted that the distance between the two bottles is greater than the length of the electric flip plate 16.

[0030] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
