Description

Technical Field

[0001] This utility model relates to the field of paperboard production technology, and in particular to a paperboard production creasing mechanism. Background Technology

[0002] Cardboard is usually made from various plant fibers, and sometimes non-plant fibers are added. It is made on a cardboard machine. A creasing machine is a machine used to cut various sheet materials, such as cardboard, corrugated cardboard, plastic and leather. It is widely used in the printing, packaging, decoration and plastics industries. It is divided into manual creasing machines and automatic creasing machines.

[0003] A search revealed a paperboard creasing mechanism under publication number CN222756177U, comprising a processing frame, an adjustment component at the lower end of the processing frame, multiple placement plates on the adjustment component, a pressure groove on the upper part of each placement plate, a top plate on the upper inner side of the processing frame, and a creasing component on the top plate for use with the pressure groove. The creasing component includes an electric push rod, a connecting sleeve, two connecting plates, and two pressure plates. The electric push rod is located at the upper end of the top plate, and the connecting sleeve is located at the lower end of the electric push rod. Both connecting plates are inserted into the connecting sleeve, with one end of each connecting plate extending through the interior of the connecting sleeve. This invention, when used to creasing paperboard, can adapt to the creasing requirements of paperboard boxes of different sizes and specifications, and eliminates the need to replace the pressure plates, thus greatly ensuring the processing efficiency of the paperboard boxes.

[0004] While the above solution can adapt to the creasing needs of cardboard boxes of different sizes and does not require the replacement of the pressure plate, thus greatly ensuring the processing efficiency of cardboard boxes, the presence of dust particles on the cardboard itself can cause wear and tear on the cardboard after creasing, making the creasing process less safe. Therefore, we propose a cardboard production creasing mechanism. Utility Model Content

[0005] The main purpose of this utility model is to provide a cardboard production creasing mechanism. By setting up a cleaning unit and a creasing unit, it solves the problem that because the cardboard itself is covered with dust, the dust particles will cause wear to the cardboard after creasing, making the creasing unsafe.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cardboard production creasing mechanism includes a main unit, a cleaning unit and a creasing unit disposed above the main unit, and a cleaning unit disposed inside the main unit.

[0008] The cleaning unit includes a fixed base installed on the top of the main unit, a connecting spring installed on the inner top wall of the fixed base, a cleaning frame installed at the bottom of the connecting spring, and a cleaning component disposed inside the cleaning frame.

[0009] The indentation unit includes an indentation frame installed on the top of the main unit, a hydraulic telescopic rod installed on the inner top wall of the indentation frame, and an indentation component disposed below the hydraulic telescopic rod.

[0010] Preferably, the main unit includes a U-shaped seat, a conveyor belt movably disposed inside the U-shaped seat, and a first drive motor installed at the input end of the conveyor belt.

[0011] Preferably, the cleaning component includes a fixed shaft installed inside the cleaning frame and a cleaning roller movably installed on the periphery of the fixed shaft.

[0012] Preferably, the indentation component includes a fixed box installed at the telescopic end of the hydraulic telescopic rod, a movable groove formed on the side wall of the fixed box, a gear movably installed inside the fixed box, a second drive motor installed at the input end of the gear, a rack movably passing through the movable groove and meshing with the gear, and an indentation plate installed at one end of the rack located outside the fixed box.

[0013] Preferably, the integral structure composed of the rack and the indentation plate is divided into two sets, and the two sets of integral structures composed of the rack and the indentation plate are arranged on opposite sides of the gear.

[0014] Preferably, the cleaning unit includes a rotating shaft movably disposed inside the U-shaped seat and located below the conveyor belt, a cleaning roller mounted on the side wall of the rotating shaft, and a third drive motor mounted on the input end of the cleaning roller.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, through the inclusion of a cleaning unit and a creasing unit, when cardboard needs to be creasing, the cardboard is placed on a conveyor belt for transport. Under the elastic force of the connecting spring, the cleaning components inside the cleaning frame remain in contact with the surface of the cardboard. The cleaning rollers adhere dust to the surface of the cardboard, thus achieving dust removal before creasing and preventing wear caused by dust particles, thereby improving safety during creasing. After the dust removal is completed, the second drive motor drives the gear to rotate, and the gear meshes with the rack until the distance between the two creasing plates matches the creasing requirements of the cardboard. Then, the hydraulic telescopic rod extends and retracts, moving the creasing components up and down to complete the creasing work. This allows for convenient adjustment of the distance between the two creasing plates according to the creasing requirements of cardboard boxes of different sizes. Attached Figure Description
