我们设计了一种结构简单的10″×12″振动式滤线器,安装在点片摄影架后面,和点片联动(总称为振动式点片联动式滤线器)。滤线器厚1.8公分,重1.5公斤。使用时只要移动点片,滤线板就会自动来回摆动。主要结构如图所示。 1.滤线板,用废旧的粗纹滤线板裁制,如用轻型的密纹板则更好; 2.振动子,由弹簧片和微型轴承组成; 3.滑轮架,减少起动时的摩擦力; 4.联动板,用螺丝固定在点片架上; 5.滑杆,使点片架在滤线器上任意滑动,以保证不论摄全片或左、右半片时,片子的中线始终和滤线板的中线对准。本滤线器具有无噪音,结构简单,摆动
We designed a simple structure of 10 “× 12” vibrating filter installed in the back of the film camera stand, and the point film linkage (collectively referred to as vibrating point piece linked filter). Filter thickness of 1.8 cm, weight 1.5 kg. As long as the use of moving points, the filter board will automatically swing back and forth. The main structure as shown. 1. The filter board, the use of scrapped coarse filter board cut, such as the use of light-dense plate is better; 2. Vibrator, by the spring and micro-bearings; 3. Pulleys, to reduce the starting time Friction; 4. linkage plate, fixed with screws in the spot rack; 5. slider, the spot rack in the filter on any slide, to ensure that regardless of the film or the left and right half, the film’s center line Always align with the center line of the filter plate. The filter has no noise, simple structure, swinging
