[0002] A large number of handbags are needed in modern life, and the handbag machine is an automatic handbag forming equipment. The equipment needs to be able to automatically complete the bag making, folding, and bottom gluing processes of the handbag. In the bag making process of the handbag machine, it is first necessary to use the creasing wheel to press multiple indentations on the paper so that it can be folded into the corresponding paper bag shape according to these indentations in the subsequent process. In order to ensure that it can adapt to paper bags of different sizes, there are high requirements for the position of the indentation, and the creasing wheel needs to be able to be adjusted in the axial position and fixed after adjustment.

[0003] In the prior art, after searching, it was found that on September 14, 2011, the applicant Wenzhou Zhengbo Printing Machinery Co., Ltd. designed the "Axial Positioning Self-locking Device for Crimp Wheels", and the recorded scheme stated that "a row of rack-shaped slots are axially arranged on the outer circumferential surface of the Crimp Wheel shaft, and the first and second radial through holes are axially arranged on the inner wall of the axial hole of the Crimp Wheel, and an axial through hole is arranged on the side of the Crimp Wheel, and the axial through hole intersects the first and second radial through holes perpendicularly, and a tongue pressing block is installed in the axial through hole, and a protrusion is arranged on the upper surface of the middle part of the tongue pressing block, and the protrusion abuts against the shaft. On the upper surface of the inner wall of the through hole, the tooth block is installed in the first radial through hole from top to bottom and is connected to the inner end of the tongue pressing block, the spring and the set screw are installed in the first radial through hole from bottom to top in sequence, and the top end of the spring is against the lower surface of the tongue pressing block, the pressure pin is installed in the second radial through hole and is against the lower surface of the outer end of the tongue pressing block. We can find that the technology designs a wire pressing wheel, a tongue block and a spring, but the overall structure is very complicated, which is not conducive to maintenance and processing. In view of this, the applicant designs a completely different technical solution. Utility Model Content
