Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, specifically to a positioning device for powder dispensing. Background Technology

[0002] In the filling process of a tube-type airflow powder filling machine, ideally, the filling needle is inserted into the bottle mouth to prevent powder from spilling out of the bottle mouth during the filling process. However, if the non-standard vial has a small mouth, the filling needle cannot be inserted into the bottle and can only be filled above the bottle mouth. In this case, some powder will spill onto or around the bottle body. If the filling volume is large and the outer diameter of the filling needle is larger than the bottle mouth, filling cannot be performed.

[0003] CN106477081B discloses an airflow-injection type powder filling machine comprising: a buffer turntable; an accelerating turntable receiving vials from the buffer turntable; a feed star wheel receiving vials from the accelerating turntable; a feed sector star wheel dividing the vials from the feed star wheel into three groups and changing the continuous motion of the three groups of vials to intermittent motion; and a conveyor belt conveying the three groups of vials to the filling station in an intermittent motion manner. Next to the dispensing station is a powder tray containing medicine powder; a dispensing mechanism that draws medicine powder from the powder tray and dispenses it into each vial at the dispensing station; a discharge fan-shaped star wheel that divides the dispensed vials from the conveyor belt into three groups and changes the intermittent motion of the three groups of vials to continuous motion; and a stoppering mechanism that continuously stops each vial from the discharge fan-shaped star wheel; it discloses a structure for accurate dispensing, but it still cannot guarantee accurate dispensing for vials with different mouth sizes. Utility Model Content

[0004] The technical problem this invention aims to solve is the issue of powder spillage during the filling process of vials with different mouth sizes.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] First, a positioning device for powder dispensing is provided, including a conveying mechanism for conveying containers to be filled and a material picking station;

[0007] A positioning mechanism is provided above the conveying mechanism. The positioning mechanism includes a positioning sleeve. The positioning sleeve has a first conical hole (21) for positioning the bottle mouth. A lifting mechanism is connected to the positioning sleeve.

[0008] A filling needle is threaded through the positioning sleeve. The filling needle is connected to a moving mechanism. The moving mechanism is used to drive the filling needle to move up and down, and can also drive the filling needle to move back and forth between the material picking station and the positioning sleeve.

[0009] Furthermore, the conveying mechanism includes a bottle conveying plate on which several containers are placed along its conveying direction.

[0010] Furthermore, the lifting mechanism includes a lifting shaft, on which a mounting plate is provided, and on which a positioning sleeve is mounted.

[0011] Furthermore, the positioning sleeve and the mounting plate are detachably connected.

[0012] Furthermore, the lifting mechanism also includes a motor and a bracket. A synchronous belt connects the motor output shaft to the bracket. A sliding plate is mounted on the synchronous belt, and a lifting shaft is mounted on the sliding plate via a connector.

[0013] Furthermore, a dust cover is fitted onto the positioning sleeve, and a sealing ring is provided between the inner side of the dust cover and the side of the positioning sleeve.

[0014] Furthermore, the dust cover has a third conical hole for the filling needle to pass through.

[0015] Furthermore, a dust extraction pipe is connected inside the dust cover.

[0016] Furthermore, the top surface of the positioning sleeve is provided with a second conical hole that communicates with the first conical hole.

[0017] Furthermore, the moving mechanism includes a lifting and rotating plate, and the material picking station and the positioning sleeve are located on concentric circles on the rotation axis of the lifting and rotating plate.

[0018] This invention has the following advantages: The first conical hole on the positioning sleeve positions the bottle mouth of the container, and the second conical hole guides and positions the filling needle, ensuring that the filling needle is aligned with the bottle mouth during filling and preventing material spillage. Furthermore, the first conical hole allows for smooth filling even when the diameter of the filling needle is larger than the bottle mouth diameter, improving the device's performance. Simultaneously, the dust cover and suction channel ensure that any spilled powder is removed, maintaining the cleanliness of the entire device. Attached Figure Description

[0024] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] It should be noted that all directional indicators in this embodiment are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0026] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] This utility model provides a positioning device for powder dispensing, such as... Figure 1 and Figure 2 As shown, the container includes a bottle conveying plate 10 for transporting the container to be filled 50 and a material picking station 60. A filling needle 30 is provided above the bottle conveying plate 10. After the filling needle 30 picks up the material from the material picking station 60, it fills the material into the container 50 to complete one filling of the container 50.

[0029] like Figure 3 and Figure 4As shown, since the filling material is powder, if the filling needle 30 is not aligned with the container opening during the filling process, the powder may easily drift out of the bottle. Therefore, a positioning sleeve 20 is provided at the filling position. The positioning sleeve 20 has a first conical hole 21 at the position corresponding to the container 50. The first conical hole 21 positions the bottle opening. The positioning sleeve 20 is connected to a lifting mechanism. The lifting mechanism drives the positioning sleeve 20 to move downward. The first conical hole 21 guides and positions the bottle opening, and then the filling needle 31 fills the container 50.

[0030] Specifically, in this embodiment, the lifting mechanism includes a motor 43, a sliding plate 44, and a bracket 46. A lifting shaft 41 is mounted on the sliding plate 44 via a connector. A mounting plate 42 is provided on the lifting shaft 41, and a positioning sleeve 20 is mounted on the mounting plate 42. A synchronous belt 45 connects the motor 43 and the bracket 46. The sliding plate 44 is connected to the synchronous belt 45. The lifting shaft 41 is plugged into the bracket 46. When the motor 43 is working, the synchronous belt 45 drives the sliding plate 44 to move up and down, which in turn drives the lifting shaft 41 to move up and down. The movement of the lifting shaft 41 drives the mounting plate 42 to move, which in turn causes the positioning sleeve 20 to move up and down. When filling is required, the positioning sleeve 20 moves downward to position the container 50. After filling is completed, the positioning sleeve 20 moves upward to transfer the filled container 50 away and move the next container 50 to be filled to the positioning sleeve 20 for filling.

[0031] To accommodate different types of containers 50, the positioning sleeve 20 is detachably connected to the mounting plate 42 by bolts, and different positioning sleeves 20 can be replaced according to the different diameters of the bottle openings.

[0032] like Figure 4 As shown, to prevent powder spillage, a dust cover 22 is fitted onto the positioning sleeve 20. A sealing ring 23 is installed between the inner side of the dust cover 22 and the side of the positioning sleeve 20. A third conical hole 25 is provided in the dust cover 22 at the position corresponding to the filling needle 30. During the filling process, the filling needle 30 moves downward and enters the dust cover 22 under the guidance of the third conical hole 25. A dust suction pipe is connected inside the dust cover 20. When dust spills into the dust cover 22, the dust suction pipe can suck the dust away, ensuring the cleanliness of the entire equipment.

[0033] In this embodiment, the top surface of the positioning sleeve 20 is provided with a second conical hole 24 that communicates with the first conical hole 21. When the filling needle 30 moves downward, the second conical hole 24 guides and positions the filling needle 20, ensuring that the filling needle 30 can be aligned with the bottle mouth. At the same time, in order to prevent dust from adhering to the bottle mouth and affecting the stoppering effect, the small diameter of the first conical hole 21 is smaller than the diameter of the bottle mouth.

[0034] In this embodiment, the filling needle 30 is positioned between the material picking station 60 and the positioning sleeve 20 using a lifting and rotating plate 31. The lifting and rotating plate 31 is equipped with the filling needle 30, which can drive the filling needle 30 to revolve and move up and down. The material picking station 60 and the positioning sleeve 20 are located on concentric circles on the rotation axis of the lifting and rotating plate 31.

[0035] Specifically, when material needs to be picked up, the lifting and rotating plate 31 drives the filling needle 30 to revolve to the material picking station 60 to pick up the material. Then it continues to rotate, so that the filling needle 30 moves to the positioning sleeve 20. After that, the lifting and rotating plate 31 drives the filling needle 30 to move downward to carry out the filling work.

[0036] In this embodiment, two pairs of filling needles 30 are symmetrically installed on the lifting and rotating plate 31. While the two filling needles 30 on one side are picking up materials, the two filling needles 30 on the other side can perform the filling work, which effectively improves work efficiency.

[0037] It should be understood that the above description of the specific embodiments of this utility model is only for illustrating the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of this utility model should be covered by the protection scope of this utility model.
