Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a carton die-cutting mould and a die-cutting machine. Background Art

[0002] As a key equipment for post-press processing in the modern packaging and printing industry, carton die-cutting machines are mainly used to complete the precise cutting, creasing and partial folding of materials such as corrugated cardboard and cardboard. The mainstream die-cutting technologies on the market currently include flat die-cutting and round die-cutting.

[0003] Flatbed die-cutting machines are widely used in small and medium-sized batch production due to their simple structure and moderate cost. During operation, the die-cutting and creasing of the cardboard are achieved through the vertical movement between the upper and lower templates, and the two processes of die-cutting and creasing need to be carried out successively, that is, two die-cutting machines are required to complete them. If die-cutting and creasing are carried out at the same time, the creasing step will affect the accuracy of die-cutting, so two die-cutting machines are required, which leads to low production efficiency of the entire die-cutting and creasing. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a carton die-cutting die and a die-cutting machine, which solves the technical problem that the prior die-cutting and creasing processes require two die-cutting machines.

[0005] A carton die-cutting die according to an embodiment of the utility model comprises an upper die and a lower die which are vertically arranged;

[0006] The upper mold includes a connecting shaft and a mold plate, the center of the mold plate is rotatably connected to the connecting shaft, a rotating motor is provided on the connecting shaft, and the rotating motor is connected to the mold plate in a transmission manner;

[0007] The lower mold includes a fixed block and a bottom plate symmetrically arranged on both sides of the fixed block;

[0008] The upper mold plate is symmetrically provided with a cutting mold cavity and an indentation mold cavity, and the two bottom plates correspond to the cutting mold cavity and the indentation mold cavity respectively.

[0009] The technical principle of the utility model is that the cardboard first enters the bottom plate on one side and undergoes a die-cutting process through a cutting mold cavity. After that, a new cardboard enters the other bottom plate. The mold plate changes the positions of the cutting mold cavity and the creasing mold cavity by rotating a motor. The cutting mold cavity is used to carry out a die-cutting process for the new cardboard, and the creasing mold cavity is used to carry out a creasing process for the cut cardboard. That is, one die-cutting machine can be used to simultaneously complete the die-cutting and creasing processes of two cardboards, thereby effectively improving the working efficiency of the die-cutting machine.

[0010] Compared with the prior art, the utility model has the following beneficial effects: by controlling the rotation of the mold plate through a rotating motor, the relative positions of the cutting cavity and the creasing cavity are changed, which solves the technical problem that the existing die-cutting and creasing processes require two die-cutting machines.

[0011] Furthermore, the bottom plate is evenly provided with demolding elastic mechanisms, the cutting mold cavity and the indentation mold cavity of the mold plate are evenly provided with demolding protrusions, and demolding springs are provided under the demolding protrusions. The demolding protrusions on the cutting mold cavity and the indentation mold cavity correspond to the demolding elastic mechanisms on the two bottom plates respectively.

[0012] Furthermore, the demoulding elastic mechanism also includes a demoulding protrusion and a demoulding spring arranged at the lower side of the demoulding protrusion.

[0013] It assists demoulding and prevents the cardboard from getting stuck on the upper or lower mold.

[0014] Furthermore, a rectangular groove is provided on the bottom plate, an inclined hole is provided on the side of the rectangular groove, the demoulding elastic mechanism includes a T-shaped protrusion, a compression spring and an inclined top block, the large end of the T-shaped protrusion is installed in the rectangular groove, the compression spring is arranged between the T-shaped protrusion and the rectangular groove, inclined top blocks are arranged in the two inclined holes, a clamping block is provided on one side of the inclined top block, the clamping block can be inserted into the rectangular groove, and a magnet is provided on the top of the demoulding protrusion in the indentation mold cavity, and the magnet can adsorb the inclined top block.

[0015] When the cutting cavity completes the die-cutting process, the T-shaped protrusion and the compression spring will be stuck by the inclined top block; and when the creasing cavity completes the creasing process, the magnet absorbs the inclined top block and pulls the inclined top block upward, so that the T-shaped protrusion and the compression spring are not stuck and pop out smoothly to lift the cardboard.

[0016] Furthermore, the base plate and the fixed block are connected by a transmission shaft, and the transmission shaft is transmission-connected to a driving motor in the fixed block.

[0017] The bottom plate is driven to tilt by a driving motor, so that the cardboard after die-cutting and creasing can slide out easily.

[0018] According to a die-cutting machine described in an embodiment of the utility model, a carton die-cutting mold is installed in the die-cutting machine, a punching rod of the die-cutting machine is connected to a connecting shaft, and the fixing block is fixed on a working platform of the die-cutting machine.

[0019] Furthermore, support plates are provided on both sides of the punching rod, rollers are provided under the support plates, and the rollers are arranged close to the mold plate.

[0020] Used to assist in supporting the upper die.

[0021] Furthermore, support protrusions are provided on both sides of the working platform, and the support protrusions support the bottom plate.
