The distance between the opener beater and the dust rod

      The gap between the opener beater and the dust rod gradually increases from the inlet to the outlet to meet the needs of the gradual loosening of the cotton block and the increase in volume. The inlet gauge is 8mm and the outlet is 18mm. When the amount of brocade supplied is large or the cotton block is large, this corner distance needs to be enlarged accordingly. However, due to the troublesome adjustment of this distance, it is generally not adjusted when the changes in the properties of the raw cotton are not very significant.

      The distance between the dust bar and the dust bar is mainly determined by the impurity content and the amount of impurities in the fed raw cotton, and is generally adjusted within the range of 5-8 mm. Properly enlarging this distance can improve the noil rate and impurity removal efficiency of the single-hand roll machine, but white flowers should be avoided.

       The weights of the heavy hammer and the heavy hammer rod of the opener are respectively WI and w2, their rotational moments to the plate shaft are MI and Iv12, and the weight of the rocker is 72. Its rotational torque to the rocker axis is M3. In order to make the rocker plate to sense the most fluctuation of cotton stored in the cotton box, the rocker plate should always have the tendency to swing forward around the axis of the rocker plate and press the cotton pile, then MI+M2 should be larger than M3'an moment difference MI+ M2-Ms should be greater than zero. When the rocking plate swings forward, it will be under the pressure of the cotton pile in the cotton box. Let the vertical pressure of the cotton pile to the insert plate be N and the horizontal pressure to be F. The sum of the moments generated by them on the shaft of the rocking plate is M. The following formula should be satisfied in the equilibrium state,

When the cotton storage volume in the cotton box gradually increases i, M4 gradually sings louder, which will make the shaker swing backward until the cotton storage volume reaches the specified maximum value. The rocker reaches the limit position of the rear swing, and the linkage mechanism is triggered. , so that the rear cotton feeding machinery stops feeding persimmons. But at this time, the stud market is still catching cotton and outputting it outward, and the cotton storage in the cotton box gradually decreases, so M4 also decreases, and the rocking plate swings forward until the cotton storage is reduced to the minimum required by the regulations. When the value is reached, the rocking plate reaches the limit position of the front swing, and triggers the linkage mechanism, so that the rear cotton feeder starts to feed cotton. In this way, the fluctuation range of the amount of cotton stored in the j cotton box can be controlled. When the rocking board is at the limit position of the front swing, the angle α between the board and the horizontal line is called the driving angle, and the central angle y between the limit position of the rocking board and the horizontal line is called the closing angle. The angle J between the extreme positions is called the swing angle. From Figure 2-29, it can be seen that if there are any two corners of Ziquake, the third angle can be calculated from the above formula.
