Description

Technical Field

[0001] This utility model relates to powder dispensing equipment, and more particularly to a powder dispensing positioning dust removal device. Background Technology

[0002] Taking a screw-type powder filling machine as an example, to ensure accurate powder filling into vials, there are high requirements for the position of the vials at the filling station. For example... Figure 1 As shown, existing equipment typically uses synchronous belt structures, pulley structures, or traveling beam structures for bottle conveying. At the filling station, the deviation between the vial and the powder outlet of the screw filling machine is greater than 1mm. Figure 1 The 1-2 mm gap between the vial and the left-side grid can prevent some powder from being dispensed into the vial, resulting in inaccurate dispensing and dust accumulation at the dispensing station. Furthermore, due to the structural limitations of the screw filling machine, dispensing can only be done from above the vial opening, and there is a 3-5 mm height difference between the vial opening and the powder outlet, causing dust to be generated at the gap between the powder outlet and the vial opening. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a powder dispensing and positioning dust removal device with a simple structure that facilitates accurate positioning of the bottle, improves filling accuracy, and prevents dust.

[0005] As a further improvement to the above technical solution: the dust cover is provided with a first groove adapted to the powder outlet and a second groove adapted to the bottle opening.

[0006] As a further improvement to the above technical solution: both the first groove and the second groove are provided with sealing gaskets.

[0007] As a further improvement to the above technical solution: the inlet of the dust suction channel extends between the first groove and the second groove.

[0008] As a further improvement to the above technical solution: the bottle positioning component is provided with a bottle positioning groove.

[0009] As a further improvement to the above technical solution: the linkage mechanism includes a driving component, the driving component is connected to one of the bottle positioning components, a synchronization mechanism is provided between the two bottle positioning components, and a linkage mechanism is provided between the bottle conveying bottom rail and one of the bottle positioning components to rise and fall with the reciprocating movement of the bottle positioning component.

[0010] As a further improvement to the above technical solution: the bottle positioning component is provided on the slide, the slide is provided on the guide seat, the guide seat is provided with a rotating shaft and an eccentric shaft connected to the rotating shaft and arranged eccentrically, the slide is provided with a sliding groove, the eccentric shaft extends into the sliding groove, and the driving component is connected to one of the rotating shafts.

[0011] As a further improvement to the above technical solution: the synchronization mechanism includes a synchronization wheel disposed on the rotating shaft and a synchronization belt wound around the synchronization wheel.

[0012] As a further improvement to the above technical solution: the linkage mechanism includes a connecting rod, a lifting rod, and a guide sleeve disposed on the guide seat.

The lifting rod passes through the guide sleeve, and the bottle conveying bottom rail is connected to the upper end of the lifting rod.

[0013] As a further improvement to the above technical solution: a rolling element is provided at one end of the eccentric shaft that extends into the groove.

[0014] Compared with the prior art, the advantages of this utility model are: This utility model discloses a powder dispensing and positioning dust removal device. After the bottle is conveyed to the area below the powder outlet of the powder dispensing equipment, a linkage mechanism drives the bottle conveying bottom rail to rise, thereby reducing the distance between the bottle and the powder outlet and helping to prevent dust. At the same time, the bottle positioning components on both sides move closer together to clamp the bottle, which can perform secondary positioning of the bottle, aligning the bottle with the powder outlet. This helps to avoid problems such as powder not being able to enter the bottle and dust accumulation at the dispensing station, improving the accuracy of filling. The dust cover moves synchronously with the bottle positioning components, surrounding the powder outlet. The dust suction channel inside the dust cover can further remove dust through negative pressure suction, better protecting the cleanliness of the dispensing station. Compared with a fixed dust cover, the reciprocating dust cover helps to avoid the formation of sanitary dead zones in the aseptic laminar flow (fixed dust covers cannot be penetrated by laminar flow air, thus forming sanitary dead zones), meeting the requirements of aseptic dispensing. The bottle conveying bottom rail and the bottle positioning components are linked by a linkage mechanism, which helps to reduce the number of power sources and save equipment costs.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Figures 2 to 8 This invention illustrates one embodiment of the powder dispensing, positioning, and dust removal device. The powder dispensing, positioning, and dust removal device of this embodiment includes a liftable bottle conveying bottom rail 14. Bottle positioning components 2 (such as positioning plates, positioning blocks, etc.) are provided on both sides of the bottle conveying bottom rail 14, which can move closer or further apart from each other. A linkage mechanism 6 is provided between the bottle positioning components 2 and the bottle conveying bottom rail 14 to drive the bottle conveying bottom rail 14 to rise and fall and the bottle positioning components 2 to move back and forth. A dust cover 3 is provided on the bottle positioning components 2, and a dust suction channel 31 is provided on the dust cover 3.

[0029] In this embodiment of the powder dispensing and positioning dust removal device, after the bottle body 15 (e.g., vial) is conveyed to the area below the powder outlet 11 of the powder dispensing equipment, the linkage mechanism 6 drives the bottle conveying bottom rail 14 to rise, thereby reducing the distance between the bottle body 15 and the powder outlet 11, which helps prevent dust. At the same time, the bottle positioning parts 2 on both sides move closer together to clamp the bottle body 15, which can perform secondary positioning of the bottle body 15, so that the bottle body 15 is aligned with the powder outlet 11. This helps to avoid the problem of powder not being able to enter the bottle body 15 and the problem of dust accumulation at the dispensing station, thus improving the accuracy of the filling amount. The dust cover 3 moves synchronously with the bottle positioning parts 2, surrounding the powder outlet 11, specifically as follows: Figure 5 and Figure 6As shown, the dust suction channel 31 inside the dust cover 3 can further remove dust through negative pressure suction, better protecting the cleanliness of the dispensing station. Compared with a fixed dust cover 3, the reciprocating dust cover 3 helps to avoid the formation of sanitary dead zones in the aseptic laminar flow (fixed dust covers 3 will form sanitary dead zones because laminar airflow can never enter their interior), meeting the requirements of aseptic dispensing. The bottle conveying bottom rail 14 and the bottle positioning component 2 are linked by the linkage mechanism 6, which helps to reduce the number of power sources and save equipment costs.

[0030] After dispensing is completed, the bottle conveying bottom rail 14 descends, and the bottle positioning parts 2 on both sides move away from each other and disengage from the bottle body 15, as detailed below. Figure 4 As shown, this is to avoid hindering the continued downstream transport of bottle 15.

[0031] Specifically, such as Figure 2 and Figure 6 As shown, in this embodiment, the dust cover 3 is provided with a first groove 32 that matches the powder outlet 11 and a second groove 33 that matches the opening of the bottle body 15, so that the dust cover 3 can fit with the powder outlet 11 and the opening of the bottle body 15 to form a sealed dust removal area.

[0032] Furthermore, in this embodiment, sealing gaskets 34 are provided in both the first groove 32 and the second groove 33, which helps to ensure the sealing between the dust cover 3 and the powder outlet 11 and the mouth of the bottle body 15, and prevents dust leakage.

[0033] In a preferred embodiment, the inlet of the dust suction channel 31 extends between the first groove 32 and the second groove 33, which is beneficial for removing dust between the powder outlet 11 and the bottle body 15 and improving the dust suction effect.

[0034] Furthermore, in this embodiment, the bottle positioning component 2 is provided with a bottle positioning groove 21, which helps to prevent the bottle 15 from moving relative to the bottle positioning component 2 and improves stability. Preferably, the bottle positioning groove 21 is a V-shaped groove, which has a simple structure and can adapt to bottles 15 of different specifications.

[0035] See details Figure 2 , Figure 7 and Figure 8 In this embodiment, the linkage mechanism 6 includes a drive component 4, which is connected to one of the bottle positioning components 2. A synchronization mechanism 5 is provided between the two bottle positioning components 2, and a linkage mechanism is provided between the bottle conveying bottom rail 14 and one of the bottle positioning components 2, so that the two components move up and down with the reciprocating movement of the bottle positioning component 2. When dust removal is required, the drive component 4 drives the right bottle positioning component 2 to move back and forth. The left bottle positioning component 2 moves synchronously with the right bottle positioning component 2 under the drive of the synchronization mechanism 5, and the two move in opposite directions. When the right bottle positioning component 2 moves back and forth, the linkage mechanism drives the bottle conveying bottom rail 14 to move up and down, which helps to reduce the number of drive components 4 and save equipment costs.

[0036] Furthermore, in this embodiment, the bottle positioning component 2 is disposed on the slide 22, the slide 22 is disposed on the guide seat 23, the guide seat 23 is provided with a rotating shaft 24 and an eccentric shaft 25 connected to and eccentrically arranged with respect to the rotating shaft 24, the slide 22 is provided with a sliding groove 221, the eccentric shaft 25 extends into the sliding groove 221, and the driving component 4 (e.g., a motor) is connected to one of the rotating shafts 24. See details. Figure 7 and Figure 8 The driving component 4 drives the rotating shaft 24 to rotate, and the eccentric shaft 25 rotates around the rotating shaft 24. Under the guidance of the guide seat 23 (for example, through the guide rod and guide hole, or the guide rail and slider), the eccentric shaft 25 can move the slide block 22 to slide left and right during the rotation process. The eccentric shaft 25 can slide back and forth relative to the slide groove 221. That is, the slide block 22 only slides left and right and will not be driven to slide back and forth by the eccentric shaft 25. The structure is simple and the reliability is good.

[0037] In this embodiment, the synchronization mechanism 5 includes a synchronization pulley 51 mounted on the rotating shaft 24 and a synchronization belt 52 wound around the synchronization pulley 51. See details. Figure 3 When the rotating shaft 24 on the right side rotates under the drive of the driving component 4, it can drive the rotating shaft 24 on the left side to rotate synchronously through the synchronous pulley 51 and the synchronous belt 52. The structure is simple and has good reliability. Of course, in other embodiments, the synchronization mechanism 5 can also adopt gear transmission or sprocket and chain mechanism transmission, which will not be described in detail here.

[0038] Furthermore, in this embodiment, the linkage mechanism includes a connecting rod 61, a lifting rod 62, and a guide sleeve 63 disposed on the guide seat 23. One end of the connecting rod 61 is hinged to the slide 22, and the other end is hinged to the lower end of the lifting rod 62. The lifting rod 62 passes through the guide sleeve 63, and the bottle conveying bottom rail 14 is connected to the upper end of the lifting rod 62. See details. Figure 7 When the slide block 22 slides to the left, it causes the lower end of the connecting rod 61 to rotate clockwise. Under the guidance of the guide sleeve 63, the upper end of the connecting rod 61 pushes the lifting rod 62 upward, and the bottle conveying bottom rail 14 rises with the lifting rod 62. The structure is compact, occupies little space, and has good reliability. Conversely, when the slide block 22 slides to the right, it causes the lower end of the connecting rod 61 to rotate counterclockwise. The upper end of the connecting rod 61 causes the lifting rod 62 to descend, and the bottle conveying bottom rail 14 descends with the lifting rod 62.

[0039] In this embodiment, a rolling element 251 (such as a roller or rolling bearing) is provided at one end of the eccentric shaft 25 that extends into the slide groove 221. See details. Figure 8 The rolling element 251 can reduce the frictional resistance and wear between the eccentric shaft 25 and the slide groove 221, making the operation smoother.

[0040] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
