Abstract

The invention discloses a die-cutting device, which relates to the fields of printing and packaging; it includes a frame, a die-cutting cylinder, a rolling knife and an adjustment mechanism. The frame is provided with a guide rail and a rack parallel to the guide rail, and the die-cutting cylinder is slidably connected. On the track, the die-cutting cylinder is provided with a mounting hole along the radial direction of the die-cutting cylinder and through the side wall of the die-cutting cylinder. The rolling knife and the adjustment mechanism are installed in the mounting hole, and the air control shaft connected to the frame is also included. , the die-cutting cylinder is set outside the air control shaft, and the air control shaft is provided with an air inlet and a number of air chambers arranged radially along the air control shaft. One end of the air chamber is connected to the air inlet, and the air chamber is connected to the air inlet. There is a pressure reducing valve; the end of the air control shaft is fixed with a transmission gear that meshes with the rack; the adjustment mechanism includes a cylinder, a thimble located in the cylinder and a spring sleeved outside the thimble; one end of the cylinder can be Connected with the air chamber, the thimble can slide along the inner cavity of the cylinder body, and one end of the thimble is fixed with the rolling knife. The device can change the length of the cut on the packaging material.

Description

technical field [0001] The invention relates to the fields of printing and packaging, in particular to a die-cutting device. Background technique [0002] As the main equipment for realizing die-cutting and creasing, die-cutting machine plays an irreplaceable and important role in the packaging and printing industries. In the manufacturing process of the packaging bag, it is necessary to cut the packaging material to be made into the packaging bag first, and the cut packaging material can be folded to form a packaging bag. Therefore, when cutting the packaging material, it is necessary to cut the packaging material into sections, that is, it is necessary to reserve a folding part of the packaging material. [0003] The existing cutting method for packaging materials is mainly to use a roller for cutting. The roller is provided with an arc-shaped cutter. The arc length of the cutter is less than the circumference of the roller. The arc length of the cutter is the The length...
