In the process of on-pole rice noodles production,a new type of the tipping bucket mechanism is developed in order to meet the needs of continuous,fast,stable fetching and feeding. According to the function requirements of the tipping bucket mechanism,the corresponding design scheme is put forward. Through the comparison,the form of motion and transmission of tipping bucket mechanism is determined. Based on the motion mechanism of the tipping bucket mechanism,the motion model is established based on the movement of the mechanism,which is also called the double slider mechanism. On this basis,the kinematics analysis is carried out,and the change rules of the angle,angular velocity and angular acceleration with sliding block chain moved is derived. In the process of production,the motion equation of the tipping bucket is established to make the bucket rotate at a constant speed. The change rule of sliding block chain speed is obtained from the theory when the tipping bucket is used as the original moving part,and the kinematics parameters are provided for the intelligent control of the mechanism.

A novel loop heat pipe used for data center with a liquid line wick is designed, and its one-dimensional steady-state mathematical model is developed based on the energy and thermodynamic equilibrium of each component and the simulation results were validated by comparing with the experimental data in this work. The compensation chamber of the loop heat pipe was removed, and a section of capillary wick was added in the end of liquid line in order to reduce heat leakage and vapor backflow and increase working medium circulation power. The mathematical model of the novel loop heat pipe can be used to predict the operating temperature of each characteristic point with small relative errors of

Based on the traditional structure of in plane switching liquid crystal display, a cylindrical liquid crystal micro-lens array driven by interdigital electrodes is proposed, and its performance is studied. Firstly, the director distribution and relative phase difference distribution of liquid crystal molecules were calculated, which shows that this structure can be used to fabricate cylindrical liquid crystal micro-lens. Then, by comparing lenses of difference sizes, it is found that narrow electrodes should be selected for lens production, and the centre of the electrode gap should be selected as the central axis of a single liquid crystal micro-lens. Finally, a certain electrode structure is selected to explore its focal length, focusing quality and zoom time. The results show that the focal length of the liquid crystal micro-lens decreases gradually with the increase of the driving voltage. When the driving voltage is between 3 Vrms and 5.5 Vrms, the liquid crystal micro-lens has good focusing quality, and its corresponding focal length changes from 1.63 mm to 20.28 mm. Based on this structure, when the liquid crystal lens is driven by the above two voltages alternately, the time required for liquid crystal molecules to reach stability is 2.35 s and 3.87 s respectively.
