Description

Technical Field

[0001] This utility model relates to the field of cigarette box packaging printing, specifically a batch feeding mechanism for cigarette box packaging printing. Background Technology

[0002] For example, Chinese patent CN220011482U discloses a batch feeding mechanism for cigarette boxes, including two pushing devices for simultaneously feeding multiple cigarette boxes, and a frame device for supporting a rotating adjustment station. The frame device is equipped with a lifting device for switching lifting stations, and the two pushing devices are symmetrically mounted on the lifting device. The frame device includes a support platform with a drive shaft installed in the middle. A second gear is installed at the bottom of the drive shaft, and a first gear meshes with one side of the second gear. A first motor is installed below the first gear. The lifting device includes a support plate with four linear guide rails evenly distributed on it. This batch feeding mechanism for cigarette boxes, through its dual-station rotating feeding design, reduces auxiliary time and speeds up feeding; through its lifting and forward movement design, it increases the accuracy of feeding positioning; and through its gear meshing transmission design, it ensures smooth and precise transmission.

[0003] The existing feeding mechanism has a fixed positioning box structure, which cannot be adjusted to accommodate cigarette boxes of different sizes. When multiple cigarette boxes are placed side by side in the positioning box, there may be gaps between the cigarette boxes and the positioning box, and these gaps cannot accommodate another cigarette box. This causes the cigarette boxes to shift when the positioning box rotates or moves, making it impossible for the printing press to position them accurately. The boxes need to be realigned during printing. Therefore, the positioning box of the existing feeding mechanism can only be used for one size of cigarette box. When feeding cigarette boxes of different sizes, a matching positioning box must be replaced, resulting in significant limitations in the use of this feeding mechanism. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a batch feeding mechanism for cigarette box packaging printing. This technical solution solves the problem mentioned in the background art that the existing feeding mechanism has a fixed structure of positioning box, which cannot adjust the width of the positioning box according to different specifications of cigarette boxes. When multiple cigarette boxes are placed side by side in the positioning box, there may be a gap between the cigarette box and the positioning box, and this gap cannot accommodate another cigarette box. This will cause the cigarette boxes to shift when the positioning box rotates or moves, and the printing press cannot accurately position them. They need to be straightened again during printing. Therefore, the positioning box of the existing feeding mechanism can only be used for placing cigarette boxes of one specification. When placing and feeding cigarette boxes of different specifications, a matching positioning box must be replaced, which results in a significant limitation in the use of the feeding mechanism.

The rotation of the bidirectional lead screws drives the two sliding sleeves to move away from or towards each other. Then, with the cooperation of the push rod, the side plates are moved. By moving the two side plates closer together or further apart, the distance between the two side plates is adjusted, so that multiple cigarette boxes placed side by side fit snugly between the two side plates. This ensures that the cigarette boxes do not move when the U-shaped feeding plate moves or rotates. Through the combination of the above structures, this feeding mechanism can be applied to feeding cigarette boxes of different specifications, thus broadening its applicability. The length of the pusher plate is adjustable, allowing it to be adjusted to a suitable length according to the distance between the two side plates, facilitating the complete ejection of the cigarette boxes from the U-shaped feeding plate after printing.

[0015] 2. This utility model, by setting up a rotating component, a locking component, and a limiting groove, allows the worker to quickly rotate the rotating table through the rotating component. Then, the locking component and the limiting groove work together to quickly limit and fix the rotating table after rotation. Compared with the existing feeding mechanism that uses a gear motor to drive the pallet to rotate, the rotating component of this feeding mechanism rotates faster during use, saves power resources, and requires less effort to rotate, resulting in a higher cost-performance ratio.
