Fully automatic zipper machinery is environmentally friendly, stable in quality, low in heat sealing temperature, good in air tightness, strong in tension, and durable in plastic clip chains. After many tests, it can completely replace similar imported products. Now let us summarize the three major system characteristics of the automatic zipper machine: 1. Hydraulic system: The function of the hydraulic transmission system is to realize the power supply of the injection molding machine according to the various actions required by the process, and to meet the requirements of each part of the injection molding machine. Requirements for required pressure, speed, temperature, etc. It is mainly composed of various hydraulic components and hydraulic auxiliary components, among which the oil pump and the motor are the power source of the injection molding machine. Various valves control oil pressure and flow to meet the requirements of the injection molding process. 2. Electrical control system: The electrical control system and the hydraulic system cooperate reasonably, which can realize the process requirements (pressure, temperature, speed, time) and various program actions of the injection machine. It is mainly composed of electrical appliances, electronic components, instruments, heaters, sensors, etc. There are generally four control methods, manual, semi-automatic, fully automatic, and adjustment. 3. Heating/cooling system: The heating system is used to heat the barrel and the injection nozzle. The barrel of the injection molding machine generally uses an electric heating ring as a heating device, which is installed outside the barrel and is detected by thermocouples in sections. Heat conduction through the cylinder wall provides a heat source for material plasticization; the cooling system is mainly used to cool the oil temperature. Too high oil temperature will cause various failures, so the oil temperature must be controlled. Another location that needs to be cooled is near the feeding port of the feeding tube to prevent the raw material from melting at the feeding port, resulting in the raw material being unable to be fed normally.
