Technical field

The invention relates to the technical field of cigarette packaging equipment, and specifically discloses a tax stamp dotted line knife sharpening device for a tax stamp packaging machine.

Background technique

As a tax payment certificate for exported cigarettes, the tax stamp is pasted on the side of the small box of cigarette packs by means of a tax stamp device. Before pasting, the tax stamp is cut with a 45° dotted line by a dotted line knife, and the dotted line coincides with the side seam of the small box. When the lid of the small box is opened, the side seam of the lid can be opened to tear the dotted line, ensuring that the tax stamp will be invalidated. The YB55A small box transparent paper packaging machine can be used for transparent paper packaging of domestic cigarettes when the tax stamp device is detached. When engaged with the tax stamp device, it can be used for tax stamp pasting and box outer transparency of export cigarettes with tax stamps. paper packaging.

During the transportation process of tax stamps, the function of the tax stamp dotted line knife is to move with the counter stick to cut a 45-degree dotted line on the tax stamp. The function of cutting this 45-degree dotted line is to facilitate the opening of the lid of the hard-packed cigarette pack after the tax stamp is pasted on it.

Due to the long-term operation of the YB55A tax stamp packaging machine, the tax stamp dotted line knife will wear out, resulting in poor cutting quality of the 45-degree cutting dotted line on the tax stamp, including the inconspicuous cutting dotted line on the tax stamp or the wrong phase of the cutting dotted line. After the above phenomenon occurs, the process requirements for affixing tax stamps to export hard-box cigarette packs cannot be met, so the dotted line knife needs to be replaced and adjusted according to technical requirements. The dotted line knife is installed on the cylindrical cutterhead at an inclination of 45 degrees. The height of the cutting edge extending out of the cutterhead can be adjusted through the nut stud. The cutting edge curve is a spiral line located on the surface of the cylinder. The manufacturing is complicated, the precision is high, and the price is expensive. After wear and tear, they are usually replaced directly, resulting in greater waste. The invention provides an edge grinding device for a tax stamp dotted line knife, which can re-sharpen the worn tax stamp dotted line knife, and is of great significance for reusing the tax stamp dotted line knife and reducing equipment maintenance costs.

The utility model patent with announcement number CN202137699U discloses a manual blade sharpener, which includes a sharpener body. The sharpener body is provided with at least one blade fixing depression corresponding to the shape of the blade. The blade fixing depression has The sharpening part of the blade extends out of the relative position of the sharpener body, the sharpener body is also provided with a blade fixing device, and the sharpener body is also provided with a holding part; the utility model The new type is a special tool for manual sharpening of indexable blades for milling machines and lathes. It is suitable for sharpening blades with different angles and shapes. The clamping is firm and safe. It can reduce auxiliary working hours and improve the efficiency and quality of manual blade sharpening. It is suitable for fixing different specifications. blade, solving safety hazards.

Although the sharpener in the above disclosed technical solution can sharpen blades of different specifications, the blade needs to be removed from the cutterhead before sharpening. For tax stamp dotted line knives, due to the special installation angle, Disassembling and assembling back and forth will increase the installation procedure, and the angle requirements are high, resulting in installation errors and affecting product quality.
