开机前的准备： Pre-boot preparation: 1.1领复合膜：根据生产任务单的要求，确定需要加工的复合膜，到熟化室或规定位置领取复合膜。 The composite film is required according to the requirements of the production task list. The composite membrane that needs to be machined is determined to the ripening chamber or the specified position. 1.2领复合膜注意事项：检查复合膜的熟化时间和复合强度，查看复合膜上无有“工序流转单”根据“工序流转单”的序号分班组按时间先后顺序领取需要上机的复合膜。 Note: 1.2 led composite film check composite membrane curing time and strength of composite, check on the composite film is no more "process flow sheet," according to the serial number of the process flow sheet points shift according to the time sequence to get computer composite membrane. 1.3确定热封刀的规格：根据生产任务单和产品要求，确定纵、横向热封刀的数目和规格。根据相 Determine the specification of the heat sealing knife: determine the number and specification of the vertical and horizontal heat sealing knife according to the production task list and the requirement of the product. According to the phase 应的纵向和横向热封刀的位置，检查硅胶板和烫布（聚四乙烯漆布）的完好程度，必要时调整或更换。 The position of the vertical and horizontal heat sealing knife should be checked for the good condition of the silicone plate and the ironing cloth (polyethylene paint cloth) and adjust or replace when necessary. 1.4设定热封刀的温度：根据复合膜材料的性质和厚度，打开电源及各热封刀的开关，初步设定各 Set the temperature of the heat sealing knife: according to the properties and thickness of the composite film material, turn on the switch of the power supply and the heat sealing knife, and set the initial setting 热封刀的温度。 The temperature of the hot sealing knife.
