[0023] Example:

[0024] The following is combined with Figure 1-5 The utility model is described in further detail.

[0025] Cardboard folding edge wetting mechanism, such as Figure 1 and Figure 3 As shown, the main body is a gantry frame 1 with elevated tripods on both sides, and a through cavity is opened on the crossbeam of the frame 1. A sliding mechanism 2 is provided above the through cavity, and an infiltration mechanism 3 is provided at the front end of the sliding mechanism 2.

[0026] like Figure 2 As shown, the sliding mechanism 2 includes a slide rail 21 placed horizontally in the through cavity and eight running members 22 with a control module and a driving module. The eight running members 22 are installed on the slide rail 21 for reciprocating sliding. Each running member 22 can be driven and controlled independently, which is convenient for subsequent adjustment according to the guide edge line of the cardboard. Generally, the four running members 22 on the left can meet the wetting and folding of ordinary cardboard. The number of running members 22 involved can be increased if the folding structure is more complex. Each running member 22 is provided with an inclined water replenishing member at the front end, and the water replenishing member moves synchronously with the running member 22, that is, the water replenishing member can slide horizontally along the slide rail 21 with the help of the running member 22. The front end of the water replenishing member is provided with an installation port, and the water replenishing member is equipped with a special extensible water replenishing pipe. Four installation plug rods are provided in the installation port, and the installation plug rods are symmetrically arranged about the center of the installation port. The rod body of the installation plug rod is provided with a water outlet, and the water outlet is connected to the water replenishing pipe. The external wetting liquid is led from the water replenishing pipe to the installation plug rod in the water replenishing member, and then guided by the installation plug rod to the installed wetting contact 4. The wetting contact 4 is detachably connected to the water replenishing member. After the wetting contact 4 is installed, it is flush with the water replenishing member and inclined relative to the horizontal plane.

[0027] like Figure 4 and Figure 5 As shown, the rear end of the wetting contact 4 is provided with four corresponding installation slots 41 for docking the installation rod. The depth of the installation slot 41 is generally four-fifths of the length of the wetting contact 4. The water outlet on the installation rod slowly discharges liquid to uniformly and slowly wet the wetting contact 4, as well as to replenish the subsequent wetting liquid. Semi-conical protrusions are provided at both ends of the bottom of the wetting contact 4. The plane of the semi-conical protrusion faces outward and is flush with the side of the wetting contact 4. A conical protrusion is provided at the bottom center of the wetting contact 4. The two protrusions have the same height. The guide edge of the cardboard is wetted by these two protrusions, and the protrusion fits with the edge groove. Preferably, at least three slidable baffle members are provided in the through cavity, two baffle members are provided at the outermost ends, and a third baffle member is provided between the four water replenishing members on the left and the four water replenishing members on the right, which is used to limit the transmission of the cardboard. A transmission partition 5 is provided on the inner bottom surface of the through cavity. The front and rear ends of the transmission partition 5 are symmetrical and pressed downward. A conveyor belt is provided on the transmission partition 5. The conveyor belt contacts the bottom of the baffle member. The paperboard is transmitted through the conveyor belt and contacts the wetting contact 4. Driven by the conveyor belt, the paperboard moves backward relative to the wetting contact 4, and the guide edge line is aligned with the protrusion of the wetting contact 4 until the guide edge line of the entire paperboard is wetted. After the paperboard is wetted, it is more convenient to fold.

[0028] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
