Off-road vehicle winch-type photoport machine features

This Fromwinch synthetic rope ATV winch is characterized by simple structure and operation, the price is cheaper, you can use continuous film, record length unlimited, high efficiency, is currently using more mid-range photoport type. The disadvantage is that the recording accuracy and set the quasi-phase degree is slightly lower, for this phototypesetting format is generally limited to 4 or 4 open below. There are two main reasons for the accuracy of the Fromwinch 12500lbs electric winch-type Phototypesetter: the first is that the film is not evenly formed by the film, when the phototypesetter used for a certain time later is more likely to result in register accuracy decline, and the second is due to the structure itself of. The film is recorded in one direction by the film movement, the other direction by the prism rotation deflection light, the prism turns a week to record a line, if the laser spot is round
Of the film in the middle of the film can be guaranteed to be circular, and in the film on both sides of the spot shape will become oval, shadow recording accuracy. Therefore, the greater the deflection angle of the laser beam, the laser to the middle of the film and the difference between the two sides of the greater the greater the spot deformation. To solve this problem, it is necessary to increase the distance between the prism and the film, reduce the deflection angle, and limit the recording format.
