| 单翼迷宫式滴灌带生产时将配比好的多组份塑料原料放入挤出机中充分熔融，经挤出模具挤出、测径仪定径后进入成型轮，其迷宫型腔在成型轮中完成真空定型和冷却，成型后的制品经切刀切分后，分成两条，经冷却风道进入冷却水箱完成最后的冷却，已经成型的制品经牵引机送入收卷机。在生产过程中完成滴灌带的测量及控制，保证滴灌带生产中的正常运行及产品的品质。 Multicomponent plastic raw materials of single wing labyrinth type drip irrigation belt production will be fully proportioned into the machine by melt extrusion, extrusion die, extrusion gauge after sizing into the molding wheel, the labyrinth cavity in the forming wheel in vacuum forming and cooling and molding after cutting knife slitting, divided into two a cooling air duct into the cooling water tank, the final cooling products has been shaped by the tractor into the coiling machine. In the production process, the measurement and control of the drip irrigation belt are completed to ensure the normal operation and the quality of the product in the production of the drip irrigation belt. 灌带测径仪通过发射器两束特定光谱的平行光源，照在滴灌带管径变化最敏感的部位，经过特制光学滤波将周围环境的杂散光滤除后进入高灵敏工业CCD摄像机，以每分钟约4万次的速度接受图像，经由高速单片机DSP芯片处理电路、ND输入、PWM输出给比例阀控制通气量气压的大小来控制管径大小。 Irrigation belt diameter measuring instrument through two parallel light emitter specific spectrum, according to changes in diameter with drip irrigation, the most sensitive parts of the body, after a special optical filter to the surrounding environment of the stray light filtered into the highly sensitive industrial CCD camera, accept the image to about 40 thousand times per minute speed through the processing circuit, high speed DSP chip ND the input and output of the PWM to the proportional valve control ventilation pressure to control the size of diameter size. |
