The upper layer base material passing through the limit rod is respectively located in the multiple limit parts for preventing the base material from deviating. The defect of this method is that the distance between adjacent limit rings is fixed. If the product needs to be changed, the limit rod suitable for the width of the upper layer label needs to be replaced, so it is necessary to improve. SUMMARY

The telescopic end of the linear mechanism 5 is connected with a rotating shaft 401 close to the other end of the rod body 1.
[0024] In actual use, the linear mechanism 5 drives the rotating shaft 401 close to the other end of the rod body 1 to move, so that the plurality of rotating shafts 401 move synchronously, and then the plurality of first blocking rings 2 move synchronously, thereby adjusting the distance between the first blocking ring 2 and the second blocking ring 3. Then the upper label base material 8 is pulled out to be between adjacent first blocking rings 2 and second blocking rings 3, and then the bottom paper 801 used for covering the adhesive on the upper label base material 8 is torn off, so that the side of the upper label base material 8 with the adhesive is wound to the upper side of the lower label, and as the lower label moves forward, it will drive the upper label base material 8 to move synchronously, thereby completing the composite pasting of the upper label base material 8.
