How to reduce the film waste during the adjustment of bag-making machine and improve the operation efficiency

Film feeding time and heat sealing time of dingmao machine bag making machine can be set separately. On this basis, derived only ding MAO machine bag making machine functional heat sealing waiting time ". This function mainly plays an important role in the necessary adjustment operation when the bag-making machine starts or replaces the roll film. The bag-making machines of other companies, when adjusting brick transport, slow down the film feeding time in order to control the waste of film, and then adjust the operation while fine-tuning the position of heater and incision. At this time, the heater's heat sealing time, which is proportional to the film feed time, also becomes longer. In order to reduce the load of the heater, it is necessary to lower the temperature of the heater in advance.

Then, a series of fine tuning work, such as shortening the feed time of the film, confirming the heat sealing strength and the appearance of the finished bag while gradually increasing the temperature of the heater, should be done before the fine tuning is about to end and enter the formal operation. In the past, this adjustment mode not only wastes time, but also wastes more film in the adjustment process.

As for the heat sealing waiting time function of Ding MAO Machinery, in the adjustment operation stage, as long as the heat sealing time is set at 0.5 seconds, the temperature of the heater is adjusted to 200 degrees as the set value, and the feed time of the film is set at 0.25 seconds < the same as the set value in the formal operation >. In this way, the "gap" time between the heater rising after a heat seal and the next heater falling is the heat seal waiting time. This time can be set separately, assuming 1.25 seconds, it is very easy to adjust the heater or cutting position. And after the fine tuning, as long as the heat sealing waiting time is set to 0 seconds, it can be simply transferred to the formal operation.

Through this film feed time (film transfer speed) and heat sealing time (control part of the heater up and down action) respectively set the function, in the adjustment stage can greatly reduce the film waste, so as to improve the production efficiency. Heat sealing waiting time function is another important reason for ding MAO machine bag making machine to be selected by the majority of customers.
