近来对自制的日光灯晒图机做了一些改进,主要有以下几点:1.外形尺寸加大了,见图1。灯箱两侧的小门改用厚15毫米的木板制作,增加了若干φ12的小孔,以提高通风散热的能力。两侧小门装铁链,往下开,门上头安装两颗小碰珠,见图2。灯箱A部剖面图 Recently, some improvements have been made to the self-made fluorescent lamp plotters. The main points are as follows: 1. The dimensions have been increased. See Figure 1. The small doors on both sides of the light box were made of 15 mm thick wood, and a number of φ12 holes were added to improve the ventilation and heat dissipation. Install small chains on both sides of the door and open it downwards. Install two small balls on the door, as shown in Figure 2. Section A of the light box
