During the clamping operation, the plurality of movable jaws 5 or the fixed jaws 2 just fit in and correspond to the gaps of the placement device, so that the stacked paper sheets and book labels can be clamped and taken out.

[0030] As a technical optimization solution of the utility model, the cylinder 3 is located on the side away from the fixed clamping jaw 2, and the rectangular plate 1 is provided with a slide groove matching the strip plate 4. The slide groove enables the strip plate 4 to move stably on the rectangular plate 1 and also supports the strip plate 4.

[0031] As a technical optimization solution of the utility model, the buffer rod 8 is located inside the rectangular shell 7 and is symmetrically and parallelly provided with two springs 9, which are symmetrically arranged on both sides of the buffer rod 8. The two ends of the spring 9 are respectively fixedly connected to the buffer rod 8 and the rectangular shell 7, and the spring 9 enables the buffer rod 8 to move elastically and has a buffering effect.

[0032] As a technical optimization solution of the utility model, the telescopic control mechanism includes a motor 10 fixedly mounted on a rectangular housing 7. The motor 10 is located in the middle of the rectangular housing 7. The motor 10 is coaxially fixed with a wire drum 11. The motor 10 can control the forward and reverse rotation of the wire drum 11. The wire drum 11 is located inside the rectangular housing 7 and is wound with a belt rope 12. The two belt ropes 12 face the two ends of the rectangular housing 7 respectively, and the two belt ropes 12 are fixedly connected to the two buffer rods 8 respectively. When the motor 10 controls the wire drum 11 to rotate forward for one circle, the two belt ropes 12 will be reeled up, and then the two belt ropes 12 will be reset by one reverse circle. In this process, the two belt ropes 12 pull the two buffer rods 8 respectively, and under the left and right of the corresponding spring 9, the effect of approaching and separating the buffer rods 8 can be achieved.

A mounting plate 15 is fixed at one end of the sliding rod 13, and a flattening plate 16 is provided on the mounting plate 15 to slide parallel to it.

[0034] As a technical optimization solution of the utility model, an electric push rod 17 for pushing the leveling plate 16 to move is fixed on the mounting plate 15, and the length of the leveling plate 16 is longer than the length of the mounting plate 15. The electric push rod 17 can control the movement of the leveling plate 16, and can control the electric push rod 17 to move telescopically and align with the sides of the fixed clamping jaw 2 and the movable clamping jaw 5.

[0035] In the utility model, the working principle of the device is as follows:

[0036] When the device is in use, the mounting frame of the connecting frame 6 is fixedly installed with the existing mechanical arm, and the mechanical arm controls the connecting frame 6 to move the rectangular plate 1, for example, to the placement of paper and book labels. At this time, the mechanical arm controls a plurality of fixed clamps 2 and a plurality of movable clamps 5 to correspond to the upper and lower sides of the stacked paper and book labels, and then the cylinder 3 starts to control the strip plate 4 to move together with the plurality of movable clamps 5, and controls the plurality of movable clamps 5 to approach the plurality of fixed clamps 2, so as to achieve the effect of clamping the stacked book labels, and then the mechanical arm moves the paper and book labels to the sewing machine, and the cylinder 3 starts again to control the plurality of movable clamps 5 to separate from the plurality of fixed clamps 2, so as to release the paper and book labels, thereby achieving the effect of adding pages to the sewing machine.

[0037] After the addition of pages is completed, the robot arm pauses for a period of time, and the electric push rod 17 can control the movement of the flattening plate 16, and can control the electric push rod 17 to move and align with the fixed clamp 2 and the side of the movable clamp 5. At this time, the two flattening plates 16 move to the corresponding ends of the paper and book, and the motor 10 controls the wire drum 11 to rotate forward for one circle, and at the same time rewind the two belt ropes 12, and then reverses for one circle to reset the two belt ropes 12. In this process, the two belt ropes 12 pull the two buffer rods 8 respectively, and under the left and right of the corresponding spring 9, the buffer rods 8 can be approached and separated, so that the two flattening plates 16 can perform a slapping and sorting operation on the paper and book. The time when the robot arm pauses is the time when the slapping and sorting operation is performed. After the slapping and sorting operation is completed, the robot arm is reset. From the above operation, it can be seen that the device can realize highly efficient clamping and feeding operation and highly efficient sewing machine page adding operation. At the same time, it is not limited to a single clamping and feeding function. After the page adding is completed, the placed paper and book labels can be tapped and sorted at both ends to make the paper and book labels neat, thereby effectively improving the subsequent work efficiency of the sewing machine.

[0038] At the same time, the beating and sorting function of the device can be adjusted according to the length specifications of the paper, that is, the electric telescopic rods 14 at both ends can control the telescopic length adjustment of the sliding rod 13, that is, adjust the spacing between the two flattening plates 16 to meet the beating and sorting needs of papers of various lengths.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
