Characteristics of single blade labyrinth type drip irrigation tape making machine: ¡ñ The diameter of tape is controlled by diameter gauge which is explored and invented by ourselves so that the measurement and control of diameter of tape is accurate, steady and reliable. ¡ñ The main machine motor, shaping part and tractor all adopt frequency conversion control system and they have characteristics of easy adjustment, reliable performance, stable work condition and low energy consumption. ¡ñ The barrel and screw of extruder adopt alloy materials after processing of hardening and tempering and ionitriding, which has features of high-hardness, high wear-resistance and long service life. Screw of extruder adopts special design which makes raw materials plasticized well and the line works steadily. ¡ñ The heating temperature of extruder and mold die head adopts automatic-control-temperature. The accuracy of controlling the temperature is high and it also economizes the energy obviously. ¡ñ The drip irrigation tape is curled by moment electrical machinery. The drip irrigation tape can overcome the tension emerged dffectively. The machine still has the equipment to calculate the length of the drip irrigation tape. The rolling length can be settled casually below 2500m(If meter prolonging is required, it can be ordered). The rolling machine has the functions of memory and automatic alarming etc. ¡ñ The whole machine is designed moderately, reasonably, beautifully and its automation degree is high.
