The FX-320 back sealed powder automatic packaging machine is widely used for small bag packaging in pharmaceuticals, food, chemicals, pesticides, and other fields, such as automatic packaging of flour, medicinal powder, milk powder, nutritional foods, seasonings, wettable pesticide powders, and other materials. The screw type powder automatic packaging machine has back sealing (I-shaped sealing) and three side sealing (upper and lower sealing+one side sealing) according to different packaging effects. Four sided sealing (top and bottom sealing+left and right sealing). This page introduces the three sided sealed model. This machine adopts the control of the rotation angle of the stepper motor to control the extrusion amount (filling amount) of the screw. Different specifications of screws can be replaced separately to achieve precise adjustment of the filling amount within a certain range. During the packaging process, when the material in the bucket is not lower than the position of the cylinder, the measurement is relatively accurate. Storing the material too low will result in insufficient feeding of the screw and affect the extrusion volume (inaccurate filling volume). If this machine can be equipped with an automatic feeding machine, it can achieve a more automated packaging process without the need for manual feeding, saving manpower. The printing function of the production date can be optionally equipped with an electric ribbon coding machine, which can print different numbers (batch number, production team) every day by replacing the characters on the header of the coding machine; When ordering the machine, there are also other Chinese and English characters available for selection. If all the functions of this machine are fully equipped, it can automatically complete quantitative, bag making, filling, sealing (optional sealing effects such as mesh and straight lines), printing production date, cutting (cutting method: serrated cutting, easy to tear bag connection, etc.), counting until the product output is completed in one go.
