Description

Technical Field

[0001] The utility model relates to the technical field of band saw paper cutters, in particular to a cutting operation device of a band saw paper cutter. Background Art

[0002] Paper cutter is a commonly used printing auxiliary mechanical equipment, which is widely used in papermaking industry, printing plants, schools, enterprises and institutions. The main function of paper cutter is to cut paper, cardboard and other materials to meet different usage requirements. Paper cutter usually has an automatic switch system, which can automatically feed paper into the cutting area for cutting, greatly improving work efficiency. At the same time, paper cutter is also equipped with knives of different specifications to adapt to the cutting of paper of different materials and thicknesses. According to different uses and occasions, paper cutters can be divided into many types, such as manual paper cutter, CNC paper cutter, band saw paper cutter, etc.

[0003] The common cutting operation device of a band saw paper cutter is usually composed of a saw beam, a saw band (or saw blade), a guide device, a tensioning device, and a transmission mechanism. The saw band is installed on the saw beam, the guide device guides the movement trajectory of the saw band or saw blade, the tensioning device is used to adjust the tension of the saw band or saw blade, and the transmission mechanism is responsible for driving the saw beam and the saw band (or saw blade) to rotate at high speed. This is the common structure and use of the cutting operation device of the band saw paper cutter. The cutting operation device of the traditional band saw paper cutter will generate dust and debris when in use, which will scatter and fall, thereby causing harm to the cutting parts and surrounding staff. The cutting operation device of some band saw paper cutters collects dust and debris by adding dust collection equipment (such as a suction fan, etc.) around. However, this method cannot get close to the cutting structure, resulting in the inability to deal with the dust at the cutting structure in time, making the cutting structure prone to failures after long-term work. For this reason, a cutting operation device of a band saw paper cutter is proposed. Utility Model Content
