Description

Technical Field

[0001] The utility model relates to the field of die-cutting machines, in particular to a die-cutting machine for packaging and printing. Background Art

[0002] A die-cutting machine is a mechanical device used for cutting, trimming, embossing, and shaping materials. This machine uses a die-cutting tool die to engrave the required shape or pattern onto materials such as paper, fabric, plastic, leather, metal sheets, etc. It is commonly used in the packaging industry for making boxes and packaging materials.

[0003] A Chinese patent document with the authorization announcement number CN219543463U proposes a die-cutting machine for packaging and printing, including a frame and a U-shaped frame. The two vertical sides of the U-shaped frame are respectively placed on the top of the frame. A rotating mechanism for rotating the U-shaped frame is provided on one side of the frame. A strip-shaped box slides horizontally below the horizontal side of the U-shaped frame, and a first cutting knife is horizontally arranged below the strip-shaped box. A fixing mechanism for fixing the first cutting knife is provided inside the strip-shaped box, and an electric telescopic rod is vertically installed at the center of the top of the horizontal side of the U-shaped frame. The output shaft of the electric telescopic rod is installed at the center of the top of the strip-shaped box.

[0004] In the above application, although the first cutting knife can be quickly installed and disassembled, ensuring the efficiency of replacing the first cutting knife, the position after each cutting knife replacement is not fixed, resulting in an unfixed engraving position of the cutting knife on the packaging, and thus prone to printing disorder problems. Summary of the Utility Model

[0005] A die-cutting machine for packaging and printing is proposed in view of the problems in the background art.

[0006] The utility model proposes a die-cutting machine for packaging and printing, including a machine body, a knife plate, an alignment component, and a limiting member. A die-cutting plate is arranged at the lower end of the machine body, and a cylinder is arranged at the top end; the telescopic end of the cylinder is connected with a fixing plate. The knife plate is detachably connected inside the fixing plate; a die knife for engraving the packaging is arranged at the lower end of the knife plate. The alignment component is arranged on the machine body to center-align the knife plate with respect to the fixing plate. The limiting member is arranged on the fixing plate to limit and fix the knife plate.

[0007] Preferably, the alignment component includes a motor arranged on the machine body; a connecting plate one is connected to the driving shaft of the motor, and a connecting plate two is rotatably connected to the top end of the driving shaft; four rotating plates are rotatably arranged in a circumferential array on the connecting plate one; the other ends of the four rotating plates are all rotatably connected with sliding plates; one ends of the connecting plate two corresponding to the four sliding plates are all connected with slide rails; the sliding plates are slidably connected to the slide rails; the other ends of the slide rails are all connected with fixing blocks; the fixing blocks are all arranged on the machine body.

[0008] Preferably, the fixing plate is square; the four groups of slide rails are respectively parallel to the four side edges of the fixing plate.

[0009] Preferably, through holes are provided at the front and rear ends of the fixed plate, and hole grooves are provided at both the left and right ends; the sliding plate pushes the knife plate through the through holes and hole grooves provided on the fixed plate so that the knife plate is centered and aligned with respect to the fixed plate.

[0010] Preferably, a connecting groove is communicated with the lower end of the through hole; the die knife on the knife plate imprints the package through the connecting groove.

[0011] Preferably, multiple groups of limiting members are provided on the fixed plate.

[0012] Preferably, the limiting member includes a screw threadedly connected to the upper end of the fixed plate; the lower end of the screw penetrates through the fixed plate and is connected with a rubber pad.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] (1) For this die-cutting machine for packaging printing, by starting the air cylinder, the retraction of the telescopic end of the air cylinder drives the fixed plate to move upward to the lower end of the second connecting plate, and then by starting the motor, the first connecting plate and multiple rotating plates are driven to rotate, thereby driving multiple sliding plates to slide along the corresponding slide rails, and further pushing the knife plate from all directions to the center position of the fixed plate. The knife plate can be centered and aligned with respect to the fixed plate, ensuring that no matter how the knife plate is replaced, the position where the die knife presses down is always fixed, guaranteeing the accuracy of the imprinting and preventing printing errors caused by the unfixed position of the die knife.

[0015] (2) For this die-cutting machine for packaging printing, by screwing the screw, the rubber pad moves downward to limit and fix the knife plate, preventing the knife plate from shaking and generating displacement during the die-cutting process, resulting in an inaccurate cutting position of the die knife and further causing packaging printing errors.
