Product Description
The open top bag filling machine is specially designed for packing powdery and granular materials from 10 to 50 kg into open top bags. It uses the method of quantitative gravimeter and controls the feed rate with the output of the load cell to achieve the purpose of automatic packing.
There are various feeding methods for open top bag packing machines, including screw feeding, belt feeding, large and small valve feeding, vibrating feeding, etc. The equipment has a wide range of applications and can pack various powders, ultra-fine powders or fine powders, granular materials, and is widely used in all walks of life. In the actual packing process, the packing machine is usually used in combination with a sealing machine (seam sealing machine or heat sealing machine) and belt conveyor.
● Clamping device for bags
● Feeding by screw conveyor
● Feed vibrator, accuracy up to 2‰
● Belt conveyor feed
Working Principle
The open top bag filling machine consists of a control system, a feeder, a weighing sensor, a clamping device for bags, a selaing mechanism, a belt conveyor, a frame, and a pneumatic control system. The feeding system uses two-speed feeding, fast feeding ensures output, and slow feeding frequency conversion control ensures accuracy; bag clamp weighing system consists of weighing brackets, sensors and bag clamp arms; the frame supports the entire system, providing stability; The control system controls the feed valve and the bag clamp. The packing shape of the product adopts the clamping of the bag in place, and at the same time, there is enough material in the storage bin, the valve automatically opens, the material is discharged into the bag, and weighing is carried out at the same time. When the first target weight is reached, slow feed continues until the second target weight is reached, stop filling, display the final weighing and automatically lose the bag.
