Description

Technical Field

[0001] The utility model relates to the technical field of cardboard cross-cutting devices, in particular to a corrugated cardboard cross-cutting device. Background Art

[0002] Due to its corrugated structure, corrugated paper has good shock absorption and mechanical properties. It is light in weight, widely used, low in freight, and recyclable, so it is suitable for various fields. Due to different demands, cross-cutting equipment is used during production to cut the excessively long cardboard into sections to improve processing efficiency.

[0003] The cardboard cross-cutting device in the prior art can cut the cardboard very well, but there are still some shortcomings when the cardboard cross-cutting device is used for a long time. Since the cardboard needs to be cut by the cross-cutting knife, the cross-cutting knife will easily become blunt when used to cut the cardboard for a long time, affecting the cutting effect of the cardboard. Since the cardboard cross-cutting device does not have a mechanism for grinding the cross-cutting knife, it is necessary to grind the cross-cutting knife manually, which increases labor, reduces work efficiency, and poses a safety hazard.

[0004] In view of this, the present technical solution proposes a corrugated cardboard cross-cutting device to better solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a corrugated cardboard cross-cutting device in order to solve the above-mentioned problems.

[0007] A fixing frame is fixed on both sides of the inner side of the gantry, and a guide rod is movably inserted into the front and rear of the fixing frame. An adjustment plate is fixed to the end of the guide rod opposite to the cardboard cross-cutting knife. A threaded rod is threadedly connected to the middle part of the fixing frame, and the threaded rod is rotatably connected to the adjustment plate.

[0008] A whetstone seat is installed on one side of the adjustment plate opposite to the cardboard cross-cutting knife through a connector, and a whetstone is fixed on one side of the whetstone seat away from the connector, and the whetstone fits the cardboard cross-cutting knife.

[0009] In a preferred embodiment, the gantry is a U-shaped structure, and the telescopic length of the hydraulic cylinder is greater than the height of the gantry.

[0010] In a preferred embodiment, the connection between the fixing frame and the gantry frame is an L-shaped structure, and the fixing frame and the gantry frame are mounted by bolts.

[0011] In a preferred embodiment, through holes adapted to the guide rods are provided at the front and rear ends of the fixing frame, and the guide rods are inserted into the through holes.

[0012] In a preferred embodiment, a handle is fixed to one end of the threaded rod away from the adjustment plate.

[0013] In a preferred embodiment, the connector includes a fixing sleeve fixedly connected to the adjustment plate and a connecting rod fixedly connected to the grindstone seat, a spring is fixed inside the fixing sleeve, a mounting cap is threadedly connected to the left side of the fixing sleeve, the connecting rod is inserted into the mounting cap, and a limiting disk is fixed at one end of the connecting rod away from the grindstone seat, and the limiting disk is inserted in the workbench and connected to the other end of the spring.

[0014] In a preferred embodiment, the mounting locations of the mounting cap and the fixing sleeve are both adapted threaded structures.

[0015] In a preferred embodiment, the diameter of the limiting plate is larger than the inner diameter of the connection point between the connecting rod and the mounting cap.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effect of the utility model is: it is convenient to better grind the cardboard cross-cutting knife with a whetstone, so that the cardboard cross-cutting knife is sharper when used, and the cardboard can be better cut.

[0017] 1. In the present invention, the hydraulic cylinder drives the cardboard cross-cutting knife to move its position, and at this time the cardboard cross-cutting knife can cut the cardboard on the workbench.

[0018] 2. In the present invention, the threaded rod is rotated by the handle, and the threaded rod drives the adjustment plate, the grindstone seat and the grindstone to move toward the position of the cardboard cross-cutter, so that the grindstone fits the cardboard cross-cutter. When the cardboard cross-cutter moves up and down, the cardboard cross-cutter rubs against the grindstone, and the cardboard cross-cutter can be polished, making it sharper when used, and the cardboard can be cut better.
