[0023] This specific embodiment is a ribbon clamping mechanism, and its structural schematic diagram is as follows Figure 1-Figure 5As shown, the clamping mechanism is installed inside the ribbon sticking machine body 1, and the clamping mechanism includes a gear 3 fixedly connected to the output end thereof, and the clamping mechanism also includes a rack 4 meshingly connected to the gear 3, and a mounting plate 5 is fixedly connected to the bottom of the rack 4, and a first cylinder 6 is fixedly connected to the mounting plate 5, and a sliding plate 7 is fixedly connected to the output end of the first cylinder 6, and a second cylinder 8 is fixedly connected to the sliding plate 7, and a fixed clamping jaw 9 is fixedly connected to the bottom of the second cylinder 8, and an L-shaped plate 10 is fixedly connected to the output end of the second cylinder 8, and a movable clamping jaw 11 is fixedly connected to the L-shaped plate 10, and a through groove 15 for the fixed clamping jaw 9 and the movable clamping jaw 11 to extend out and enter the interior of the ribbon sticking machine body 1 is provided on the top front side of the ribbon sticking machine body 1.

[0024] The motor mounting plate 21 is fixedly connected to the inner wall of the ribbon attaching machine body 1 , and the motor mounting plate 21 supports and fixes the motor 2 .

[0025] The mounting plate 5 is provided with a slide groove matched with the sliding plate 7, and the sliding plate 7 is slidably connected in the slide groove. The setting of the slide groove can prevent the sliding plate 7 from being offset during the movement.

[0026] The rack 4 is slidably installed inside the ribbon sticking machine body 1 through a sliding assembly. The sliding assembly includes a sliding rod 12 fixedly connected to the rack 4 and a sliding rail 13 fixedly connected to the inner wall of the ribbon sticking machine body 1. The sliding rod 12 cooperates with the sliding rail 13, and the sliding rod 12 is slidably connected to the sliding rail 13. The rack 4 can drive the sliding rod 12 to slide on the sliding rail 13 during the up and down movement. The coordinated setting of the sliding rod 12 and the sliding rail 13 can guide the movement of the rack 4.

[0027] A fixing block 14 is sleeved on the top of the rack 4 and the sliding rod 12, and the fixing block 14 is fixedly connected to the inner wall of the ribbon attaching machine body 1. A through hole for lifting and lowering the rack 4 and the sliding rod 12 is opened in the middle of the fixing block 14. Through the setting of the through hole, the rack 4 and the sliding rod 12 can move in the vertical direction, and can also play a certain guiding role in the movement of the rack 4 and the sliding rod 12.

[0028] There is a gap between the rack 4 and the sliding rod 12 and the motor mounting plate 21. The setting of the gap can satisfy the movement of the rack 4 and the sliding rod 12 in the vertical direction.

[0029] Working principle: the motor 2 drives the gear 3 to rotate clockwise, and the gear 3 can drive the rack 4 to move downward when it rotates clockwise. The rack 4 can drive the mounting plate 5 to move downward during the downward movement. The mounting plate 5 can drive the first cylinder 6 and the sliding plate 7 to move downward during the downward movement. The first cylinder 6 can also drive the sliding plate 7 to slide in the slide groove in the direction away from the ribbon sticking machine body 1 during the downward movement. When the sliding plate 7 moves downward, it can also drive the second cylinder 8 to move downward synchronously. The second cylinder 8 can drive the movable jaw 11 and the fixed jaw 9 to move downward during the downward movement. Therefore, when the gear 3 rotates clockwise, it can drive the first cylinder 6, the sliding plate 7, the second cylinder 8, the movable jaw 11 and the fixed jaw 9 to move downward synchronously, and when the whole moves downward, the first cylinder 6 can drive the movable jaw 11 and the fixed jaw 9 to extend from the through groove opened in the ribbon sticking machine body 1. The ribbon is positioned between the fixed clamp 9 and the movable clamp 11, and the bottom of the ribbon is positioned on the fixed clamp 9. At this time, the motor 2 is turned off, and the second cylinder 8 drives the L-shaped plate 10 to move downward. The L-shaped plate 10 can drive the movable clamp 11 to move downward until the movable clamp 11 and the fixed clamp 9 clamp the ribbon. Similarly, when the motor 2 drives the gear 3 to rotate counterclockwise, it can drive the first cylinder 6, the sliding plate 7, the second cylinder 8, the movable clamp 11 and the fixed clamp 9 to move upward synchronously, and when the first cylinder 6 drives the sliding plate 7 to slide in the first slide groove toward the direction close to the ribbon sticking machine body 1, the fixed clamp 9 and the movable clamp 11 can extend into the interior of the ribbon sticking machine body 1 through the through groove opened in the ribbon sticking machine body 1 during the upward movement. That is to say, under the action of the clamping mechanism, it can move both vertically and horizontally, and the ribbon can be moved to the paper box pasting place for pasting through the clamping mechanism.

[0030] To sum up, the utility model can realize automatic clamping of the ribbon through the setting of the clamping mechanism, and can move the ribbon to the pasting place of the paper box, and use the clamping mechanism to paste the ribbon to the paper box. Compared with manual positioning and pasting, it has the advantages of accurate positioning, high efficiency and low defective rate.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
