[0024] The quick-release assembly includes a support plate 15 placed horizontally on the vertical pole 2, and a fixing pin 16 is vertically arranged on the top of the support plate 15. A fixing hole matched with the fixing pin 16 is arranged on the mounting block 8, and a boss 17 is arranged on the top of the fixing pin 16. The diameter of the boss 17 is smaller than the diameter of the fixing pin 16, and a locking ring 18 is sleeved on the boss 17. The outer diameter of the locking ring 18 is the same as the diameter of the fixing pin 16 and the inner diameter thereof is larger than the diameter of the boss 17. A lockable pin cap 19 is also arranged on the top of the boss 17, and the pin cap 19 tightens the locking ring 18 to the boss 17.

[0029] The working principle of the utility model is as follows: the cardboard is conveyed in the conveying mechanism of the carton forming machine. When conveyed to the position of the crimping wheel 5 and the pre-pressing wheel 6, the pre-pressing wheel 6 will first pre-press the surface of the cardboard, which makes a shallow indentation on the surface of the cardboard, and then the crimping wheel 5 will perform secondary crimping along the position of the pressed shallow indentation, so as to produce the required indentation on the surface of the carton. According to the different specifications of the cardboard and the processing requirements, the depth of the surface indentation also has different requirements. The regulating cylinder 3 is controlled to make it move up and down with the wheel seat 4, the crimping wheel 5 and the pre-pressing wheel 6. When the regulating cylinder 3 controls the wheel seat 4 to move downward, the crimping wheel 5 and the pre-pressing wheel 6 will be closer to the cardboard, so that the pressed indentation is deeper, and when the regulating cylinder 3 controls the wheel seat 4 to move upward, the crimping wheel 5 and the pre-pressing wheel 6 will be away from the cardboard, so that the pressed indentation will be shallow, so that the depth of the indentation on the cardboard surface can be adjusted.
