1. The hourly output of the pillow packing machine was originally designed to be 60 tons / hour. At present, one third of enterprises have increased to more than 70 tons / hour, the highest of which has exceeded 90 tons / hour, which is 50% higher than the original design.

2. In the original design of the pillow type packaging machine, opening and closing the shutter is an operation that must be completed for each package of product. The mechanical failure rate of the shutter is high, which increases the labor intensity of workers. Some enterprises have replaced the original mechanical control machine with an electromagnetic (or pneumatic) control machine to achieve automatic bag unloading and increase the degree of automation of the packaging machine.

3． The weighing part of the original packaging machine uses a mechanical lever scale. It has the disadvantages of large size, low weighing accuracy, easy wear of the knife edge and holder, and large displacement during weighing. At present, many companies using pillow packaging machines have applied electronic scales to packaging machines, replacing mechanical lever scales, and have initially achieved the effects of high measurement accuracy, fast speed, and easy automatic control. Full automation broke a new path.
