Automatic doffing trolley of spinning machine
The invention relates to an automatic doffing trolley of a spinning machine. The automatic doffing trolley comprises a doffing trolley body and an automatic doffing device. The automatic doffing device is arranged on a bottom plate located on the upper portion of the doffing trolley body. A pre-loosening mechanism of the automatic doffing device is arranged on the bottom plate of the doffing trolley body through a spring steel plate. A pre-loosening block is fixed on the spring steel plate. When the trolley moves forwards, the pre-loosening block moves forwards along with the trolley, is inserted into the lower end of a bobbin, and enables the lower end of the bobbin to ascend along an oblique plane of the pre-loosening block. Then, under the action of a plane cam, the pre-loosening block abuts against the lower end of the bobbin, moves upwards in the direction parallel to the axis of a spindle blade and enables the full bobbin to break away from the spindle blade under the blocking action of a spindle hook. The bobbin bounced upwards enters a manipulator device. The upper ends of claws of the manipulator device clamp the upper end, without yarn, of the full bobbin and then pull the full bobbin out. The pre-loosening force of the pre-loosening mechanism is parallel to the axis of the spindle blade and has little influence on a spindle bearing. The manipulator device clamps the upper end, without the yarn, of the bobbin, and the quality index of the yarn can not be influenced.

System and method for producing and culturing liquid spawns of edible fungus
The invention discloses a system and a method for producing and culturing liquid spawns of an edible fungus. The system comprises a nutrient solution sterilized tank, a heat exchanger, a cooling-water machine set and a plurality of liquid spawn culture tanks, and further comprises a nutrient solution circulation pipeline, a nutrient solution sterilization and cooling pipeline, a nutrient solution conveying pipeline, a germ-free compressed air inlet pipeline, a blow-off pipeline and a liquid spawn conveying pipeline. The invention further discloses a method for producing and culturing the liquid spawns of the edible fungus by using the system. According to the system and the method provided by the invention, residue spawns in the liquid spawn culture tanks can be used as stock cultures for again culture, so that the infection risks due to successive vaccination can be avoided; the sterilization, the cooling, the conveying and the germ-free air supply of the spawns are completed in inclosed vessels and pipelines, so that the infection probability is zero; the movement of the liquid spawn culture tanks is avoided, so that the investment is reduced, safety and reliability are realized, the amount of used labor is reduced, and the labor intensity is reduced.
