A) High quality technical personnel
Workshop technicians in addition to have professional technical knowledge, but also need to be very familiar with the operation of cutting equipment, more need to have a serious attitude.
B) clean and dust-free cutting environment
Carbon belts are easily affected by the environment in the process of production and cutting. The carbon strip is easy to absorb dust particles in the air, which will produce some white particles during printing, affecting the quality of the carbon strip. Therefore, the production and slitter of carbon belt must be completed in a clean and dust-free workshop environment, and the appropriate temperature and humidity of the workshop should be maintained to reduce the influence of dust on the production and slitter of carbon belt.
C) High quality slitting of carbon belt requires imported slitting equipment
The width of each roll of carbon belt is in millimeters. In the slitting workshop, the imported carbon belt slitting machine is essential to quickly and accurately slitting the carbon belt with a length of several hundred meters or thousands of meters into the specifications and lengths required by customers. The production speed of the old carbon belt scutters is very slow, and the width of the scutters can not be accurately controlled, resulting in large errors. Now the newly imported carbon belt scutters can not only meet the needs of fast scutters of manufacturers, but also accurately control the quality of carbon belts. Among them, the tension of carbon belt scutters and the flatness of carbon belt rewinding are the key points of production control.
C.a) effect of tension control on carbon band swarming
The control of tension will affect the tightness of carbon tape rewinding. When the tension is too high, the PET film with carbon strip will be extended and damaged, and the ink layer attached to the film will react, so it will cause the quality problem of carbon strip powder, such as the printing effect is not clear, and the scattered toner will pollute the goods and other serious quality problems.
But when the cutting tension of the carbon belt is too small, the carbon belt is easy to produce wrinkles, and the printing will present white lines, indentation and other poor printing quality problems. In addition, too small tension will lead to poor quality problems such as tube core movement and carbon slippage during transportation or assembly.
Each imported carbon belt slitting machine in the new set after the assembly still need to complete a lot of configuration and debugging work, in order to find the cutting quality carbon belt the most appropriate tension range, and this data is the key data after our technical personnel to carry out the necessary machine maintenance.
C.b) the effect of flatness control on carbon rewinding
The base film of the carbon strip is a PET film. In the printing process, the printer automatically stops its tension adjustment, and there will be a tensile force between the supply axis and the recovery axis. At this time, the force of the carbon strip will not be easily disconnected only when the force is average. Therefore, when rewinding the carbon strip, the carbon strip needs to be completely flat and keep parallel with the tube core, so that the edge of the carbon strip will have an average force and is not easy to break during the printing process. If the carbon tape rewinding is not smooth, the carbon tape will produce creases in the printing process, showing white lines, indentation and other problems of poor printing.
