The size of the dust grid enclosing arc depends on the possibility of the machine structure. Appropriately increasing the dust grid enclosing arc, that is, increasing the number of dust rods, can increase the amount of debris, but this needs to be adapted to a certain degree of looseness. Too many dust sticks will not have much effect. The commonly used dust grid enclosing arc is 1/4-3/4 of the circumference of the hitter
A structure of elastic flat steel dust rod dust grid and triangular dust rod dust grid. In terms of design, the position of the dust grid seat should be adjustable to achieve appropriate spacing between the beater and the dust grid. To adapt to the situation where cotton blocks gradually loosen and increase in volume, this spacing is generally smaller at the inlet and larger at the outlet.
The wall panel for installing the dust grid seat has long holes to adjust the position of the dust grid seat. The adjustment of the installation angle and spacing of the dust grid is achieved by adjusting the position of the adjustment plate. The new machine design has conveniently placed this adjustment on the handwheel outside the machine.
Elastic flat steel dust rod is placed in the gap between the dust grid seat and the adjustment plate; The two ends of the triangular dust rod are welded to the adjustment rod and the fulcrum block, respectively. One end of the adjustment rod is hinged to the pin of the dust grid seat, while the other end is hinged to the pin of the adjustment plate. Whether it is the gap position or pin position of the dust grid seat and adjustment plate, as well as the geometric shape of the dust grid seat and adjustment plate, they should be determined using graphical methods based on the two extreme positions of the dust rod during design.
