By adjusting the position of the fixing bolt 39 in the long slot 38, the height of the arc-shaped pressing plate 37 can be adjusted, which can be used in cooperation with cardboard of different thicknesses and is convenient for adjustment.

[0026] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, etc. that are mature in the prior art. The machines, parts and equipment all adopt conventional models in the prior art. Plus, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0027] At the same time, the content not described in detail in this specification all belongs to the well-known prior art of those skilled in the art.

[0028] The implementation principle of a corrugated cardboard indentation device in this application is as follows:

[0029] When in use, the cardboard is placed into the chassis 1 and inserted under the conveying roller 31. Then, the height of the arc-shaped pressing plate 37 can be adjusted according to the thickness of the cardboard. When adjusting, first loosen the fixing bolt 39, then push the fixing bolt 39 to slide and adjust in the long slot 38 to change the position of the arc-shaped pressing plate 37. When adjusting to a suitable position, tighten the fixing bolt 39 to fix it. During operation, with the cooperation of the driving wheel 34 and the belt 35, the pulley 33 and the conveying roller 31 can be driven to rotate, and the roller wheels 32 on the conveying roller 31 can push the cardboard forward, which is convenient for loading and unloading.

[0030] In addition, with the cooperation of the drive motor 25, the cam 24 can be driven to rotate. When the cam 24 disengages from the upper inclined rod 23, it can push the upper inclined rod 23 to move downward. Since the bottom end of the upper inclined rod 23 is hinged to the lower inclined rod 22, and the bottom end of the lower inclined rod 22 is hinged to the knife press 21, the knife press 21 can be pushed to squeeze the cardboard downward, pressing a crease on the cardboard. For continuous reciprocating operation, a reciprocating spring 26 is also installed between the upper inclined rod 23 and the top wall of the chassis 1. When the long side of the cam 24 moves away from the upper inclined rod 23, with the cooperation of the reciprocating spring 26, the upper inclined rod 23 can be pulled back to its original position, thereby regularly pushing the knife press 21 to slide up and down, facilitating the creasing operation.

[0031] In addition, the position of the cam 24 can be changed by adjusting the electric push rod 243. Since the upper inclined rod 23 is inclined, when the cam 24 slides, the contact part with the upper inclined rod 23 will also change, resulting in a change in the frequency of the downward movement of the upper inclined rod 23. The frequency of the downward pressure of the knife press 21 can be controlled, and the spacing of the creases on the cardboard can be changed, facilitating adjustment.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
