Description

Technical Field

[0001] This utility model mainly relates to the technical field of double-hole double-pressure cutter mechanism for carbonless printing paper, specifically a double-hole double-pressure cutter mechanism for carbonless printing paper. Background Technology

[0002] Customized printing paper is often needed in commercial activities. This type of printing paper is also known as cash register paper. It mainly refers to the paper roll used in cash registers to record cash transaction details. Cash register paper consists of at least two layers or more, so it is thicker than ordinary printing paper. When used for cash registers, the paper is mainly cut horizontally. During the cutting process, the cutting starts from the edge of the paper's surface coating. Since the surface coating contains a large amount of highly abrasive inorganic pigments, the higher the cutting force, the greater the wear on the cutter. Over time, the pressing parts inside the machine body are more likely to loosen, leading to poor cutting results in the later stages. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a double-hole, double-pressure cutter mechanism for carbonless printing paper. This invention utilizes the extension of a telescopic rod to drive a connecting plate downwards. The movement of the connecting plate drives a punching rod and a cutter downwards. The punching rod first contacts the printing paper and punches holes on both sides of the paper using pressure. Then, the cutter contacts the printing paper and cuts it along the edges of the holes on both sides, thereby improving cutting efficiency, reducing cutter wear, extending cutter lifespan, and ultimately providing greater convenience for users.

Two perforated rods, distributed laterally, are installed on the front side of the bottom of the connecting plate. A cutter is installed on the front side of the bottom of the connecting plate, located between the two perforated rods. A horizontal plate is installed on the bottom side of the inner wall of the box body via a support rod. A paper roller support device is provided at the bottom of the box body.

[0006] Furthermore, the paper roller support device includes two vertical plates distributed on the left and right, and each vertical plate is equipped with a locking rod, which can engage with the paper roller.

[0007] Furthermore, the two perforated rods are tapered.

[0008] Furthermore, the bottom edge of the cutter is inclined, with the left side higher and the right side lower.

[0009] Further, the bottom surface of the connecting plate is connected with spring mounting blocks on both sides, and a compression roller is rotatably mounted between the two mounting blocks.

[0010] Further, the top surface of the horizontal plate is provided with two through holes distributed left and right, a knife slot is arranged between the two through holes, and a strip-shaped through groove is arranged at the rear side of the top surface of the horizontal plate.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] The stretching of the telescopic rod can drive the connecting plate to move downward, the movement of the connecting plate can drive the punching rod and the cutter to move downward, the punching rod first contacts the printing paper and punches the two sides of the printing paper through pressure, then the cutter contacts the printing paper, and the cutter cuts the printing paper along the hole edges of the two sides of the printing paper, thereby improving the cutting efficiency, reducing the wear of the cutter, prolonging the service life of the cutter, and further conveniently using.
