Intorduction Belt conveyor as an important bulk material conveying equipment, and its obvious advantages, has been widely used in every industry.
To avoid such problems, the roller into permanent block, while the tape is magnetized, using the same poles repel magnetic force generated by non-contact magnetic material handling.
Conclusion The foregoing analysis and calculations show that, if the conveyor belt outside the tiny magnetic interference, both the X and Y directions, the magnet support system can be spontaneously adjusted to the stable equilibrium state, but is limited to a slight interference Design displacement, and if the external source of interference is strong, it may result in failure of the adaptive regulation, such as large displacement deviation phenomenon and material contained mutations increases, etc., if the above phenomenon is encountered, only by means of the external Additional adjustment system to make corrections, such as the addition of suitable anti-magnetic cushion belt conveyor deviation tensioning device, magnetic aligning roller group class or transporting materials for screening before blanking.

To modify a rough metal surface by materials with low surface free energy is main method; it could be known that the rough structure is necessary for preparing the metal superhydrophobic surface.
Here, PP was used as the low surface free energy material to coat the surface of aluminum alloy.
The obtained materials possess superhydrophobicity after treated with pp.

They are material supply module, sealing module, cutting module, frame module, power module, conveyor module, packaging film module and the electric or control system module according to characteristics of vertical four edge-sealing bag packaging machine.
The reconstruction of application for: when productivity and bag length are increased, we can raise the motor speed, conversely, reduce motor speed. when bag width and the column number of bag are changed, we can use new longitudinal sealing roller, horizontal sealing roller, coding roller, longitudinal cutting roller, horizontal cutting roller and fracture line roller to replace olds under adjusting distance of two supporting plates, in witch the other parts are normal use and the frame module is unchanged and material supply module only change the material tube number.
For example: the column number of bag of material supply module, sealing module and cutting module is the same or not, the bag width of material supply module, sealing module and cutting module is the same or not, the width and thickness of two supporting plate of material supply module, sealing module and cutting module are the same or not, the height of frame module whether meets combined height requirements of material supply module, sealing module and cutting module, and the dimensions and parameters of engine whether correspond to material supply module, sealing module and cutting module.
