[0020] 3. In order to further reduce the complexity of wiring between the regulating drive motor and the wiring contact A, the utility model sets the wiring contact A on one side of the station to reduce the complexity of wiring between the regulating drive motor and the wiring contact A. The utility model adopts a cylinder as a wiring drive component, which is low in cost and sensitive in response. The cylinder itself has a certain amount of redundancy. By controlling the air pressure in the cylinder, it can ensure that the wiring contact A and the wiring contact B are in good contact, avoiding the situation where poor contact between the wiring contact A and the wiring contact B affects the operation of the regulating drive motor.

[0021] 4. In order to avoid the influence of the wiring contact B on the rotation of the turntable, the utility model sets the wiring contact B on one side of the turntable mounting seat, and sets a through hole on the turntable mounting seat. When the adjustment drive power supply needs to be turned on, the wiring drive component drives the wiring contact B through the through hole to contact the wiring contact A to supply power to the adjustment drive motor. Such an arrangement can also make the structure between the turntable and the turntable mounting seat more compact.

[0022] 5. The adjustment assembly of the utility model is different from the existing gear rack adjustment assembly. The adjustment assembly of the utility model adopts the structural form of adjusting worm, adjusting worm wheel and adjusting screw. The worm, worm wheel and screw have self-locking properties. Compared with the existing gear rack adjustment assembly structure, the adjustment assembly of the utility model uses the characteristics of the worm wheel, worm and screw to achieve self-locking. After adjustment, it can ensure that the spacing between the movable plate and the left side plate remains unchanged. The gear rack structure also needs to add a locking structure to avoid the gear rack moving during operation and changing the spacing between the movable plate and the left side plate.

DETAILED DESCRIPTION

[0027] The following are exemplary embodiments of the present invention that are combined with the accompanying drawings to help fully understand the claims and their equivalents, wherein the specific details are only considered as exemplary and do not limit the scope of the present invention. Therefore, those of ordinary skill in the art can make various changes and modifications to the embodiments without departing from the scope and spirit of the present invention.

[0028] As a preferred embodiment of the present invention, refer to the attached specification Figure 1 , Attachment Figure 2 and attached Figure 3As shown, this embodiment discloses a multi-station turntable device, including a turntable 1 and a turntable mounting seat 2 for supporting and assembling the turntable 1, wherein a plurality of stations 3 are evenly distributed in the circumferential direction of the turntable 1, and a left side plate 4, a movable plate 5 and an adjustment component are installed on the station 3; the left side plate 4 and the movable plate 5 are arranged in parallel to form a clamping mechanism, and the adjustment component is configured to drive the movable plate 5 to move so as to adjust the distance between the movable plate 5 and the left side plate 4; an adjustment drive motor 7 is installed on the turntable 1, and a wiring contact A8 is arranged on the turntable 1, and the wiring contact A8 is connected to the adjustment drive motor 7, and a wiring contact A8 is arranged on the turntable mounting seat 2 There is a wiring contact B9; the wiring contact B9 is assembled on the turntable mounting base 2 through the wiring drive component 10; when the distance between the movable plate 5 and the left side plate 4 needs to be adjusted, the wiring contact A8 on the turntable 1 is rotated to a position corresponding to the wiring contact B9 on the turntable mounting base 2, and the wiring drive component 10 drives the wiring contact B9 to move toward and contact the wiring contact A8, and the wiring contact B9 is connected to the wiring contact A8 to provide power for the adjustment drive motor 7, and the adjustment drive motor 7 drives the adjustment components of multiple stations 3 to run synchronously through the transmission component to synchronously adjust the distance between the movable plates 5 and the left side plates 4 of the multiple stations 3.

[0029] Compared with the prior art, the utility model sets an adjustment drive motor 7 on the turntable 1, and drives the adjustment component to synchronously adjust the distance between the movable plate 5 and the left side plate 4 of each workstation 3 by adjusting the drive motor 7. The adjustment speed is fast and the downtime for adjustment is short, which can effectively improve the adjustment efficiency and thus improve the production and packaging efficiency.

[0030] The adjustment drive motor 7 needs a power line for power supply, and the turntable 1 rotates continuously in the working state, which brings difficulties to the layout of the power line of the adjustment drive motor 7. If a ring-shaped power connection ring is set to power the adjustment drive motor 7, the equipment cost will be greatly increased. The adjustment drive motor 7 does not need to maintain power supply continuously, and power supply is only required when the spacing between the movable plate 5 and the left side plate 4 is adjusted. Therefore, in order to further simplify the power line layout structure and cost of the adjustment drive motor 7, this embodiment adopts a wiring contact pair to supply power to the adjustment drive motor 7. When the spacing between the movable plate 5 and the left side plate 4 needs to be adjusted, the wiring contact A8 on the turntable 1 is rotated to a position corresponding to the wiring contact B9 on the turntable mounting seat 2, and the two wiring contacts are docked to realize the power supply to the adjustment drive motor 7, thereby realizing electric adjustment, simplifying the power supply structure of the adjustment drive motor 7.

[0031] As an implementation method of this embodiment, only one wiring contact A8 may be provided on the side of the turntable 1 close to the turntable mounting seat 2 to facilitate the connection between the wiring contact B9 and the wiring contact A8.

[0032] As a preferred implementation of this embodiment, multiple groups of wiring contacts A8 are evenly arranged on the side of the turntable 1 close to the turntable mounting seat 2, so that the turntable 1 can more quickly achieve the correspondence between the wiring contacts A8 and the wiring contacts B9.

[0033] As another implementation of this embodiment, the number of the wiring contacts A8 is consistent with the number of the workstations 3 on the turntable 1, and the wiring contacts A8 are arranged on one side of the workstations 3 on the turntable 1 to reduce the complexity of wiring between the adjustment drive motor 7 and the wiring contacts A8.

[0034] As another implementation of this embodiment, the wiring drive component 10 is a driving cylinder, and the wiring contact B9 is assembled at the extended end of the driving cylinder. When the distance between the movable plate 5 and the left plate 4 needs to be adjusted, the wiring contact A8 on the turntable 1 rotates to a position corresponding to the wiring contact B9 on the turntable mounting seat 2, and the driving cylinder extends to drive the wiring contact B9 to connect with the wiring contact A8. In this implementation, a cylinder is used as the wiring drive component 10, which is low in cost and sensitive in response. The cylinder itself has a certain amount of redundancy. By controlling the air pressure in the cylinder, it can be ensured that the wiring contact A8 is in good contact with the wiring contact B9, avoiding the situation where the wiring contact A8 and the wiring contact B9 have poor contact and affect the operation of the adjustment drive motor 7.

[0035] As another implementation method of this embodiment, refer to the attached Figure 2 As shown, the turntable mounting seat 2 is provided with a through hole 11 for the wiring contact B9 to pass through and connect with the wiring contact A8. In order to prevent the wiring contact B9 from affecting the rotation of the turntable 1, the present embodiment sets the wiring contact B9 on one side of the turntable mounting seat 2, and sets the through hole 11 on the turntable mounting seat 2. When the adjustment drive power supply needs to be turned on, the wiring drive assembly 10 drives the wiring contact B9 to pass through the through hole 11 and contact the wiring contact A8 to supply power to the adjustment drive motor 7. Such an arrangement can also make the structure between the turntable 1 and the turntable mounting seat 2 more compact.

[0037] Different from the existing rack and pinion adjustment assembly, the adjustment assembly of this embodiment adopts the structural form of adjusting worm 12, adjusting worm wheel 13 and adjusting screw 14. The worm, worm wheel and screw have self-locking properties. Compared with the existing rack and pinion adjustment assembly structure, the adjustment assembly of the utility model uses the characteristics of worm wheel, worm and screw to achieve self-locking. After adjustment, it can ensure that the spacing between the movable plate 5 and the left side plate 4 remains unchanged, while the rack and pinion structure needs to add a locking structure to prevent the rack and pinion from moving during operation and changing the spacing between the movable plate 5 and the left side plate 4. The utility model adopts the worm and gear structure as the adjustment assembly, which further simplifies the structure.

[0038] As an example of this embodiment, the movable plate 5 is further provided with a guide post 17, and the right side plate 6 is provided with a guide sleeve 18 for the guide post 17 to slide and penetrate, so as to ensure the stability of the movable plate 5 during the movement.
