DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A hot melt adhesive labeling machine with a clamping structure includes a labeling machine body 1. The labeling machine body 1 is a mature product of the prior art. The labeling components arranged inside are not described in detail in this scheme. For details, please refer to the prior art.

[0022] A mounting frame 2 is provided on the labeling machine body 1, and a lifting block 4 is provided on the mounting frame 2 through a telescopic mechanism. A plurality of rotating grooves 6 are installed on the bottom wall of the lifting block 4. A transmission cavity 8 is provided inside the lifting block 4. Screws 7 extending into the transmission cavity 8 are rotatably provided in the plurality of rotating grooves 6. A driving motor 9 is provided in the transmission cavity 8. The screw 7 is connected to the driving motor 9 through a rotating mechanism. A moving rod 12 is threadedly sleeved on the screw 7. A fixing rod 14 is provided on the moving rod 12 through an elastic mechanism, and a clamping block 5 is installed on the fixing rod 14.

[0023] The telescopic mechanism includes a telescopic cylinder 3 arranged on the mounting frame 2. The telescopic end of the telescopic cylinder 3 slides through the mounting frame 2 and is fixedly connected to the lifting block 4. The telescopic cylinder 3 can be extended and retracted to realize the lifting of the lifting block 4 and the pressing block 5 and other components.

[0024] The rotating mechanism includes a transmission gear 11 installed on the end of the screw 7, and a driving gear 10 is installed on the output shaft of the driving motor 9. The transmission gear 11 is meshed with the driving gear 10. As shown in the figure, the driving gear 10 and the transmission gear 11 are both bevel gears, and are in a vertical meshing relationship with each other.

[0025] The elastic mechanism includes a spring 15 elastically connected to the moving rod 12 , a connecting groove is provided on the fixed rod 14 , and the other end of the spring 15 is elastically connected to the inner wall of the connecting groove. The spring 15 plays a buffering role and enhances the clamping effect of the clamping block 5 .

[0026] A limit rod 13 is provided in the rotating groove 6 , the limit rod 13 is parallel to the screw rod 7 , and the limit rod 13 slides through the moving rod 12 , and the limit rod 13 plays a limiting role, which can effectively prevent the moving rod 12 from rotating with the screw rod 7 .

[0027] A protective pad is installed on the outer wall of the pressing block 5. The protective pad is made of rubber material. The rubber protective pad plays a protective role and can prevent the pressing block 5 from causing squeezing damage to the compressed product.

[0028] When the utility model is used, the material completes the labeling operation in the labeling machine body 1, and the entry and exit of the material are completed by the conveying device arranged on the labeling machine body 1. When the material is in the process of moving out and is directly below the lifting block 4 and other components, the conveying device stops running and starts the telescopic cylinder 3, the telescopic cylinder 3 drives the lifting block 4 to descend, and the lifting block 4 drives the pressing block 5 to contact the label on the material, and then the telescopic cylinder 3 continues to extend. At this time, the moving rod 12 compresses the spring 15, and cooperates with the fixed rod 14 and the pressing block 5 to enhance the pressing operation of the label to ensure its pasting effect.

[0029] In this solution, the size of the label will change, so it is necessary to adjust the spacing between the multiple clamping blocks 5. The adjustment steps are: start the drive motor 9 to drive the active gear 10 to rotate, and the active gear 10 cooperates with the transmission gear 11 to drive the screw 7 to rotate. When the screw 7 rotates, the moving rod 12 threadedly installed on it will drive the fixed rod 14 and the clamping block 5 to move. When it is adjusted to the appropriate spacing, the drive motor 9 can be turned off.

[0030] 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.
