Description

Technical Field

[0001] The utility model relates to the technical field of transfer paper cutting, in particular to a cutting device for heat sublimation transfer paper. Background Art

[0002] A slitter is a mechanical device that slits wide-width paper, mica tape or film into multiple narrow-width materials, and is commonly used in papermaking machinery, wire and cable mica tape, and printing and packaging machinery. When producing and processing heat sublimation digital transfer paper, it is necessary to slit wide-width paper. Sometimes, it is necessary to cut papers with different widths on the same slitter. Therefore, it is necessary to develop a transfer paper slitting structure with a freely adjustable slitting distance.

[0003] A transfer paper slitting structure with a freely adjustable slitting distance described in a patent document with the publication number of CN218593091U changes the slitting shaft and the slitting knife into a split type. At the same time, an adjustment area is arranged on the slitting shaft. The slitting knife can adjust its position in the adjustment area through screw thread cooperation to adjust the distance between two adjacent slitting knives, and then the slitting knife is positioned by an elastic buckle, so as to slit transfer papers with different widths.

[0004] However, there are still certain defects in the actual use of this device. Since the slitting knife is in screw thread cooperation in the adjustment area, when the operator adjusts the position of the slitting knife, he will contact the slitting knife, causing a safety hazard; and because the annular blade rotates around the slitting shaft in a circular motion to cut the paper, it is easy to displace along the screw thread direction under the action of friction during cutting, thereby affecting the cutting width.

[0005] Based on this, a cutting device for heat sublimation transfer paper is now provided, which can eliminate the disadvantages of the existing device. Summary of the Utility Model
