Description

Technical Field

[0001] The invention relates to the technical field of adhesive tape production equipment, in particular to a slitting mechanism of an adhesive tape slitting machine. Background Art

[0002] In the process of tape production, an eight-axis slitting machine is needed to slit the tape. The tape slitting machine is a machine that can cut the tape into several narrower tapes. The tape is pulled out by the rotation of the roller, and then cut by the knife to be cut into several narrower tapes. Finally, each narrow tape is curled on the receiving roller.

[0003] During the tape strip cutting process, heat is generated by the friction between the blade and the tape material and the plastic deformation of the material. Frictional heat comes from the interaction between the contact surface of the blade and the tape, while plastic deformation heat comes from changes in the internal structure of the material. Experimental data show that about 98%-99% of the cutting energy is converted into heat energy, of which the shear surface deformation heat is dominant, followed by the front face friction heat. Heat accumulation will cause the blade temperature to rise, causing three major problems: Deterioration of material properties: The tape may soften and become more sticky due to the increase in temperature, resulting in sticking to the knife, deformation of the cut, or adhesion of the tape. Shortened blade life: High temperature accelerates blade wear, reducing its hardness and wear resistance. Industrial tests show that for every 10°C increase in tip temperature, the blade life may be shortened by 30%-50%. Reduced processing accuracy: Thermal deformation will affect the stability of cutting dimensions. Especially in precision manufacturing, the error may reach more than 0.1mm.

[0004] In the existing technology, the tool is mostly cooled by spraying coolant externally. However, when cutting tape, the external coolant is easily splashed onto the tape, thereby affecting the quality of the tape. At the same time, the angle of the spray port needs to be adjusted multiple times to meet different cutting size requirements, which reduces the overall processing efficiency.
