摘要针对内镶贴片式滴灌带生产过程中在生产线选盘中滴头易反片、倒片,造成产品合格率低的问题,研究以提高滴灌带产出合格率为目标,创新设计了集正反面流道、中心打孔框和正反流道同一梳型进水口的滴头结构,并研制出高效内镶贴片式滴头。生产的内镶贴片滴灌带达到美国工程师协会(ASAE)和国际标准组织(ISO)中A类产品标准,水力性能好,产出合格率提高了2.97%,有效地解决了滴灌带生产过程中滴头反片、倒片的问题,提高了产品合格率。

AbstractThe inlaid patch type drip irrigation with production process in the production line of the selected disk anti sheet, rewind, caused low output of qualified rate. With improving the qualification of drip irrigation belt products as the goal, the positive and negative flow, center punch frames and shared comb type water inlet dropping head structure was designed, efficient embedded chip drop head was developed. Production of inlaid drip irrigation belt to achieve product standard of the American Society of Mechanical Engineers (ASAE) and the international standards organization (ISO) in class A, output to improve the qualified rate of 2.9%, an effective solution to the drip irrigation belt production process for film, rewind, and improve the qualified rate of the product output.

内镶贴片式滴灌带生产过程中滴头的传送是利用选盘旋转产生的离心力将滴头甩至选盘边缘的卡轨中,再不断运送到输送轨道进行滴灌带的生产。在生产线选盘上设计有多个选片气嘴,利用气流分别将堆叠的、未卡在卡轨中的反片、倒片滴头吹离卡轨,确保滴头在进入输送轨道是滴头流道成型面朝上,保证滴灌带的正常生产。但由于气嘴气流可靠性相对较差,不能完全吹走卡在卡轨内的反片及倒片,易导致设备故障,造成合格滴灌带产出率下降。在公司调查显示,内镶式贴片滴灌带生产中12%左右故障是由反片、倒片引起的,而此类故障直接导致的产品废品率占总废品率的12%以上。因此,设计一种生产加工时降低反片、倒片的现象的内镶片式滴头,对于保证生产的连续性和稳定性、降低机械故障率、提高滴灌带产出合格率是十分必要的。……
