Description

Technical Field

[0001] This utility model relates to the field of star wheel conveying technology, and in particular to an adjustable conveying star wheel and a capping machine. Background Technology

[0002] After the bottles are filled, they need to be conveyed to the capping machine's capping head for capping. The bottles are usually conveyed by a star wheel conveyor, which separates the rows of bottles one by one, arranging them in an orderly manner before they enter the capping head for capping.

[0003] A common star wheel conveyor system includes a star wheel shaft, a bottle neck star wheel at the top of the shaft, several spaced-apart bottle neck slots on the outer circumference of the bottle neck star wheel, and a bottle body star wheel fitted onto the star wheel shaft below the bottle neck star wheel. The bottle body star wheel has several spaced-apart bottle body slots on its outer circumference. The bottle body star wheel is detachably connected to the bottle neck star wheel via several circumferentially spaced support pillars. During assembly, the bottle neck star wheel should be installed on the star wheel shaft first, ensuring the central axis of the bottle neck slots coincides with the axis of rotation of the capping head. Then, multiple support pillars are used to connect the bottle neck star wheel and the bottle body star wheel. However, due to assembly tolerances, the central axis of the bottle body slots may be spaced from the central axis of the bottle neck slots after installation. This prevents the bottle from simultaneously fitting into both the bottle neck and bottle body slots, requiring disassembly and adjustment of multiple support pillars for repeated calibration, which is time-consuming and affects the efficiency of the star wheel conveyor system's installation and debugging. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable conveyor star wheel and a capping machine. It has a simple structure and can rotate and selectively fix the second star wheel so that the central axis of the first gear groove and the central axis of the second gear groove are aligned, thus ensuring the installation efficiency of the adjustable conveyor star wheel.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] In a first aspect, an adjustable conveying star wheel is provided, comprising a drive shaft, a first star wheel, a second star wheel, and an adjusting member. The drive shaft is rotatably mounted on a machine base, and the axis of rotation of the drive shaft extends vertically. The first star wheel and the second star wheel are spaced apart on the drive shaft along the vertical direction, with the first star wheel located above the second star wheel. The outer peripheral wall of the first star wheel is evenly provided with a plurality of first deflector grooves around its own central axis, the first deflector grooves being used to define the bottle mouth. The outer peripheral wall of the second star wheel is evenly provided with a plurality of second deflector grooves around its own central axis, the second deflector grooves being used to define the bottle body. Along the vertical direction, each first deflector groove corresponds to a second deflector groove. The second star wheel is mounted on the drive shaft via the adjusting member, which can rotate around the central axis of the drive shaft and be selectively fixed, so as to rotate the second star wheel so that the central axis of the second deflector groove coincides with the central axis of the first deflector groove.

[0007] In one embodiment, the adjusting member includes a clamp, which includes a first connecting block and a second connecting block that are detachably connected. The first connecting block and the second connecting block are respectively provided with mounting grooves on their adjacent sides, and the two mounting grooves form a clamping groove for clamping the transmission spindle.

[0008] In one embodiment, the adjustable conveyor wheel further includes a first turntable for supporting the bottle, the first turntable being disposed on the drive shaft, and the clamp being disposed on the first turntable.

[0009] In one embodiment, the adjusting member further includes support rods, and multiple support rods are detachably connected to the clamp. The length of the support rods extends along the vertical direction, and all the support rods are detachably connected to the bottom side of the second star wheel.

[0010] In one embodiment, the second star wheel includes a third connecting block and a fourth connecting block, the third connecting block being detachably connected to the first connecting block via a plurality of the support rods, and the fourth connecting block being detachably connected to the second connecting block via a plurality of the support rods.

[0011] In one embodiment, one of the adjacent sides of the third connecting block and the fourth connecting block is provided with a positioning groove, and the other is provided with a positioning part, the positioning part being inserted into the positioning groove.

[0012] In one embodiment, the third connecting block is provided with the positioning groove, and the fourth connecting block is provided with the positioning part. The positioning groove forms an insertion interface at least through one side of the third connecting block along the vertical direction. A limiting part is provided protruding from the groove wall of the positioning groove and adjacent to the groove opening of the positioning groove. The limiting part is used to prevent the positioning part from coming out of the groove opening of the positioning groove.

[0013] In one embodiment, the adjustable conveying star wheel further includes a first arc-shaped guard plate, which is disposed on the machine base and spaced apart from the outer periphery of the first star wheel. The length of the first arc-shaped guard plate extends along the rotation direction of the first star wheel, and the bottle mouth is slidably disposed between the first dial groove and the first arc-shaped guard plate; and / or,

[0014] The adjustable conveyor wheel also includes a second arc-shaped guard plate, which is disposed on the machine base and spaced apart from the second star wheel. The length of the second arc-shaped guard plate extends along the rotation direction of the second star wheel, and the bottle body can be slidably disposed between the second dial groove and the second arc-shaped guard plate.

[0015] In one embodiment, the adjustable conveying star wheel further includes a transmission sub-shaft and a third star wheel. The transmission sub-shaft is rotatably mounted on the machine base, and the rotation axis of the transmission sub-shaft extends along the vertical direction. The transmission sub-shaft is spaced apart from the transmission main shaft. The third star wheel is mounted on the transmission sub-shaft and is located between the first star wheel and the second star wheel. The outer peripheral wall of the third star wheel is evenly provided with a plurality of third deflector grooves around its own central axis. When the bottle body is engaged between the second deflector groove and the third deflector groove, the central axis of the second deflector groove coincides with the central axis of the third deflector groove.

[0016] Secondly, a capping machine is provided, including a capping head and the aforementioned adjustable conveying star wheel. The capping head is slidably disposed above the adjustable conveying star wheel in a vertical direction. When the capping head rotates, the rotation axis of the capping head is respectively aligned with the central axis of the first dial groove and the central axis of the second dial groove.

[0017] The beneficial effects of this utility model are:

[0018] This utility model discloses an adjustable conveyor star wheel. By adjusting the second star wheel on the transmission main shaft, the second star wheel can be driven to rotate when the adjusting component rotates around the central axis of the transmission main shaft. This allows for precise alignment of the central axis of the second gear slot with the central axis of the first gear slot, ensuring that the bottle can be smoothly inserted into both the first and second gear slots simultaneously. This significantly saves time during installation and debugging, and effectively improves the overall fitting accuracy and assembly efficiency of the adjustable conveyor star wheel.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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 based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] like Figures 1 to 6As shown, an adjustable conveying star wheel in this embodiment includes a drive shaft 1, a first star wheel 2, a second star wheel 3, and an adjusting component 4. The drive shaft 1 is rotatably mounted on the machine base, and the axis of rotation of the drive shaft 1 extends vertically. The first star wheel 2 and the second star wheel 3 are spaced apart on the drive shaft 1 vertically, with the first star wheel 2 located above the second star wheel 3. The outer peripheral wall of the first star wheel 2 is evenly provided with a plurality of first deflector grooves 21 around its own central axis. The first deflector grooves 21 are used to limit the bottle mouth 10 of the bottle 100. 1. The outer peripheral wall of the second star wheel 3 is evenly provided with multiple second deflector grooves 31 around its own central axis. The second deflector grooves 31 are used to define the bottle body 102 of the bottle 100. In the vertical direction, each first deflector groove 21 is provided with a corresponding second deflector groove 31. The second star wheel 3 is set on the transmission main shaft 1 through an adjusting member 4. The adjusting member 4 can rotate around the central axis of the transmission main shaft 1 and be selectively fixed so that the second star wheel 3 is rotated so that the central axis of the second deflector groove 31 coincides with the central axis of the first deflector groove 21. That is, both the first deflector groove 21 and the second deflector groove 31 are arc-shaped grooves. During installation, the first star wheel 2 is fixed so that the first deflector groove 21 is aligned with the rotation axis of the capping head 200. Then, the adjusting member 4 is rotated so that the second star wheel 3 on the adjusting member 4 rotates, thereby aligning the central axis of the second deflector groove 31 with the central axis of the first deflector groove 21. Then, the adjusting member 4 is fixed to the transmission main shaft 1.

[0033] It is understandable that by setting the second star wheel 3 on the transmission main shaft 1 through the adjusting component 4, the second star wheel 3 can be driven to rotate when the adjusting component 4 rotates around the central axis of the transmission main shaft 1. This precisely adjusts the alignment of the central axis of the second gear wheel groove 31 with the central axis of the first gear wheel groove 21, ensuring that the bottle 100 can be smoothly inserted into the first gear wheel groove 21 and the second gear wheel groove 31 at the same time. This greatly saves time in the installation and debugging process and effectively improves the overall fit accuracy and assembly efficiency of the adjustable conveyor star wheel.

[0034] Furthermore, such as Figure 2As shown, the adjusting component 4 includes a clamp, which includes a detachably connected first connecting block 41 and a second connecting block 42. Mounting grooves are respectively formed on adjacent sides of the first connecting block 41 and the second connecting block 42, creating a clamping groove 43 for holding the transmission spindle 1. The first connecting block 41 and the second connecting block 42 are connected to clamp the transmission spindle 1, providing a stable clamping connection. This results in a simple structure and convenient disassembly, assembly, and adjustment. Simply moving the first connecting block 41 and the second connecting block 42 away from each other to open the clamping groove 43 allows the clamp to rotate. For example, the first connecting block 41 and the second connecting block 42 are arranged along a first direction. The first connecting block 41 has a threaded hole facing the second connecting block 42, and the second connecting block 42 has a through hole corresponding to the threaded hole. A bolt passes through the through hole and is screwed into the threaded hole to connect the second connecting block 42 to the first connecting block 41. Adjustment is convenient; simply loosening the bolt allows the clamp to rotate.

[0035] Optionally, such as Figure 1 As shown, the adjustable conveyor star wheel also includes a first turntable 5 for supporting the bottle 100. The first turntable 5 is mounted on the transmission main shaft 1, and the clamp is mounted on the first turntable 5. The first turntable 5 effectively supports and conveys the bottle 100. Combined with the first star wheel 2 limiting the bottle mouth 101 and the second star wheel 3 limiting the bottle body 102, this ensures that the bottle 100 remains stably in the predetermined position during conveying, reducing the possibility of the bottle 100 shifting or tilting due to vibration or external forces. Furthermore, the clamp, mounted on the first turntable 5, effectively supports the clamp, further improving the installation stability and reliability of the clamp.

[0036] Furthermore, the adjusting component 4 also includes support rods 44. Multiple support rods 44 are detachably connected to the clamp, and the length of the support rods 44 extends vertically. All support rods 44 are detachably connected to the bottom side of the second star wheel 3. By setting the support rods 44, the second star wheel 3 can be spaced above the first turntable 5, which can prevent the cap that falls from the capping head 200 onto the first turntable 5 from getting stuck with the second star wheel 3, thus improving the safety and operational stability of the adjustable conveyor star wheel.

[0037] Preferably, since current blow molding machines can produce several bottle types, and these bottle types typically have the same neck shape during blowing, while the bottle body shape varies, and the capping machine models are mostly fixed and relatively standard, only the appropriate second star wheel 3 needs to be replaced when the bottle body shape changes. Therefore, the second star wheel 3 includes a third connecting block 32 and a fourth connecting block 33. The third connecting block 32 is detachably connected to the first connecting block 41 via multiple support rods 44, and the fourth connecting block 33 is detachably connected to the second connecting block 42 via multiple support rods 44. When the second star wheel 3 needs to be replaced, simply detach the third connecting block 32 and the fourth connecting block 33 from the support rods 44 respectively and install new third connecting blocks 32 and the fourth connecting block 33 adapted to the product model.

[0038] Of course, support rods of different heights can also be replaced according to different bottle support requirements.

[0039] In addition, such as Figure 4 As shown, compared to the monolithic ring structure, when the second star wheel 3 needs to be replaced, its detachable connection between the third connecting block 32 and the fourth connecting block 33 facilitates direct disassembly and replacement. This reduces the need to remove other structures such as the first star wheel 2 to extract the second star wheel 3 from the transmission spindle 1, thus improving the convenience of replacing the second star wheel 3. Taking the third connecting block 32 as an example, the support rod 44 has a threaded hole, and the third connecting block 32 has a through hole. Bolts are screwed through the through hole into the threaded hole to connect the third connecting block 32 to the support rod 44, making disassembly and assembly convenient.

[0040] In some embodiments, such as Figure 5 As shown, a positioning groove 34 is provided on the side of the third connecting block 32 facing the fourth connecting block 33, and a positioning part 35 is provided on the side of the fourth connecting hole facing the third connecting block 32. The positioning part 35 is inserted into the positioning groove 34. Through the insertion and cooperation of the positioning part 35 and the positioning groove 34, the alignment accuracy of the third connecting block 32 and the fourth connecting block 33 can be effectively improved. Of course, in addition to the positioning groove 34 being provided on the side of the third connecting block 32 facing the fourth connecting block 33 and the positioning part 35 being provided on the side of the fourth connecting hole facing the third connecting block 32, the positioning groove 34 can also be provided on the side of the fourth connecting hole facing the third connecting block 32 and the positioning part 35 is provided on the side of the third connecting block 32 facing the fourth connecting block 33. Alternatively, both the third connecting block 32 and the fourth connecting block 33 can be provided with positioning parts 35 and positioning grooves 34. These are not all illustrated here.

[0041] Furthermore, taking the example of a positioning groove 34 on the third connecting block 32 and a positioning part 35 on the fourth connecting block 33, the positioning groove 34 forms an insertion interface at least through one side of the third connecting block 32 in the vertical direction. A limiting part 36 protrudes from the groove wall of the positioning groove 34 and is located near the groove opening of the positioning groove 34. The limiting part 36 is used to prevent the positioning part 35 from dislodging from the groove opening of the positioning groove 34. Through the cooperation of the limiting part 36 and the positioning part 35, the connection stability between the third connecting block 32 and the fourth connecting block 33 can be effectively improved, and the connection gap between the third connecting block 32 and the fourth connecting block 33 can be reduced.

[0042] Of course, the third connecting block 32 and the fourth connecting block 33 can be connecting blocks with the same structure. When the third connecting block 32 and the fourth connecting block 33 are connected, they are stacked about the center of the rotation axis of the transmission main shaft 1. Both the third connecting block 32 and the fourth connecting block 33 are provided with a positioning part 35 and a positioning groove 34.

[0043] In some embodiments, such as Figure 1 As shown, the adjustable conveyor star wheel also includes a first arc-shaped guard plate 6. The first arc-shaped guard plate 6 is disposed on the machine base and spaced apart from the outer periphery of the first star wheel 2. The length of the first arc-shaped guard plate 6 extends along the rotation direction of the first star wheel 2. The bottle mouth 101 of the bottle 100 can be slidably disposed between the first gear groove 21 and the first arc-shaped guard plate 6. The first arc-shaped guard plate 6 effectively protects the stability and safety of the bottle 100 during the conveying process, while reducing possible friction and collision between the bottle mouth 101 of the bottle 100 and the first star wheel 2, thus reducing the risk of damage. The length of the first arc-shaped guard plate 6 extends along the rotation direction of the first star wheel 2, providing continuous support for the rotation of the bottle 100 around the transmission main shaft 1, allowing the bottle mouth 101 to slide smoothly between the first gear groove 21 and the first arc-shaped guard plate 6, ensuring that the bottle 100 does not tilt or jam.

[0044] Optionally, the adjustable conveyor wheel also includes a second arc-shaped guard plate 7. The second arc-shaped guard plate 7 is disposed on the machine base and spaced apart from the second star wheel 3. The length of the second arc-shaped guard plate 7 extends along the rotation direction of the second star wheel 3. The bottle body 102 of the bottle 100 can be slidably disposed between the second turntable groove 31 and the second arc-shaped guard plate 7. It can be understood that the second turntable groove 31 enables the bottles 100 to be separated and transferred one by one. With the cooperation of the second arc-shaped guard plate 7, when the bottle 100 rotates on the first turntable 5, the bottle body 102 of the bottle 100 can slide stably between the second arc-shaped guard plate 7 and the groove wall of the second turntable groove 31, improving the stability and safety of the bottle 100 during the conveying process. The length of the second arc-shaped guard plate 7 extends along the rotation direction of the second star wheel 3, providing continuous support for the bottle body 102 and preventing the bottle 100 from tilting or jamming during the conveying process.

[0045] In other embodiments, such as Figure 1 As shown, the adjustable conveying star wheel also includes a transmission sub-shaft 8 and a third star wheel 9. The transmission sub-shaft 8 is rotatably mounted on the machine base, and its rotation axis extends vertically. The transmission sub-shaft 8 is spaced apart from the main transmission shaft 1. The third star wheel 9 is mounted on the transmission sub-shaft 8 and is located between the first star wheel 2 and the second star wheel 3. Multiple third deflector grooves 91 are evenly distributed around the outer peripheral wall of the third star wheel 9 along its central axis. When the bottle body 102 of the bottle 100 is engaged between the second deflector groove 31 and the third deflector groove 91, the central axis of the second deflector groove 31 coincides with the central axis of the third deflector groove 91. By introducing the transmission sub-shaft 8, which is spaced apart from the main transmission shaft 1, and the third star wheel 9 mounted on the transmission sub-shaft 8, the bottles 100 can be connected and transmitted in parallel transmission structures. For example, if a second turntable is mounted on the transmission sub-shaft 8, the connection and transmission of the bottles 100 between the first turntable 5 and the second turntable can be achieved through the placement of the third star wheel 9.

[0046] In addition, the adjustable conveyor wheel also includes a third arc-shaped guard plate, which is spaced apart from the third star wheel 9. The bottle body 102 of the bottle 100 can be slidably disposed between the third arc-shaped guard plate and the groove wall of the third turntable groove 91. It should be noted that the third arc-shaped guard plate should be partially inserted between the first star wheel 2 and the second star wheel 3 so that the bottle 100 can be guided by the third arc-shaped guard plate when it is connected between the first turntable 5 and the second turntable.

[0047] This utility model also provides a capping machine, such as Figures 1 to 6As shown, the capping machine includes a capping head 200 and the aforementioned adjustable conveyor star wheel. The capping head 200 is slidably positioned above the adjustable conveyor star wheel in a vertical direction. During capping rotation, the rotation axis of the capping head 200 coincides with the central axis of the first gear groove 21 and the central axis of the second gear groove 31, respectively. The adjustable conveyor star wheel of this capping machine uses an adjusting member 4 to mount the second star wheel 3 on the transmission main shaft 1. When the adjusting member 4 rotates around the central axis of the transmission main shaft 1, it can drive the second star wheel 3 to rotate, thereby precisely aligning the central axis of the second gear groove 31, the central axis of the first gear groove 21, and the rotation axis of the capping head 200. This ensures that the bottle 100 can smoothly and simultaneously be inserted into the first gear groove 21 and the second gear groove 31, and can be accurately positioned and capped by the capping machine. This greatly saves time during installation and debugging, and effectively improves the overall fit accuracy and assembly efficiency of the adjustable conveyor star wheel and the capping machine.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
