为了探讨影响卵形体轴向运动水平偏转角的主要因素，研究了铝质、塑料、鸡蛋和鸭蛋等4种卵形体基本特征参数和装置工作参数对卵形体水平偏转角的影响规律。结果表明，在固定输送辊中心距时，4种卵形体的水平偏转角与输送辊直径呈线性正相关关系，决定系数在0.950以上。在固定输送辊间隙时，4种卵形体的水平偏转角与输送辊直径呈线性负相关关系，决定系数在0.900以上。4种卵形体水平偏转角与输送辊间隙呈线性负相关关系，决定系数在0.900以上。输送辊转动线速度对卵形体的水平偏转角无显著影响。J/L值与卵形体水平偏转角呈线性负相关关系，决定系数为0.985。卵形体的倾角与水平偏转角呈线性负相关关系，决定系数在0.850以上。试验得出的最佳输送辊直径为Φ40 mm，最佳输送辊间隙为15~25 mm，最佳的输送辊转动线速度为50~70 mm/s。

In order to explore the main factors affecting the horizontal deflection angle of axial movement of an ovoid object, the effects of basic characteristics and device operating parameters on the horizontal deflection angle of ovoid objects (aluminum ovoid object, plastic ovoid object, chicken egg, and duck egg) were studied. The results showed that when the center distance of conveyor rollers was fixed, the horizontal deflection angle of four ovoid objects had a positive linear correlation with the diameter of conveyor rollers and the coefficient of determination was above 0.950. When the spacing of conveyor rollers was fixed, the horizontal deflection angle of four ovoid objects had a negative linear correlation with the diameter of conveyor rollers and the determination coefficient was above 0.900. The horizontal deflection angle of four ovoid objects had a negative linear correlation with the spacing of convey rollers, and the determination coefficient was above 0.900. The linear speed of conveyor roller rotation had no significant effect on the horizontal deflection angle of ovoid objects. The value of J/L had a negative linear correlation with the horizontal deflection angle of ovoid objects and the determination coefficient was 0.985. The obliquity of ovoid objects had a negative linear correlation with the horizontal deflection angle and the determination coefficient was above 0.850. The optimal operating parameters obtained from the test were as follows: the diameter of conveyor rollers: Φ40 mm; the spacing of conveyor rollers: 15-25 mm; the linear speed of the conveyor roller rotation: 50~70 mm/s.
