The utility model relates to spinning equipment technical field, concretely is a kind of automatic doffing creel lifting mechanism, it includes: shell, one end of shell is fixedly connected with servo motor, the output end of servo motor passes through one end of shell and is fixedly connected with shaft coupling, one end of shaft coupling away from servo motor is fixedly connected with screw rod, and the other end of screw rod is rotatably connected in one end of shell;The outer surface of screw rod is connected with sliding table by screw thread, and one side of sliding table is fixedly connected with mounting plate and cylinder, slot is set up in sliding table interior, and cover is slidably connected in slot, and both ends of cover are fixedly connected in both ends of shell interior;Servo motor rotates and drives screw rod to rotate, under the action of screw rod and guide rail, sliding table can move up and down, the upper supporting plate and push plate can receive creel, after being moved to specified position with sliding table drive together, cylinder drives push plate and pushes out creel, solve the problem of low doffing precision, yarn cylinder is easily damaged or posture is bad.

The application discloses a winding framework, a cake coil and a transformer, comprising at least one annular framework unit, the annular framework unit having a first axial end and a second axial end, the first axial end being provided with a first spiral groove, the second axial end being provided with a second spiral groove, the first spiral groove being provided with a first positioning port for positioning a winding start end of a first wire cake, the second spiral groove being provided with a second positioning port for positioning a winding end of a second wire cake, a cake-to-cake turning opening being arranged at a position where the first spiral groove and the second spiral groove are connected, and the cake-to-cake turning opening being used for bending a winding tail end of the first wire cake to a winding start end of the second wire cake. The winding framework can realize the winding of positive and negative cakes without the cake turning operation, the winding is very simple, the production efficiency is significantly improved, and in addition, the bending operation of the wire is greatly reduced due to the cake turning operation, and then the risk of internal wire breakage damage is reduced.

The invention discloses a cathode-free solid-state battery based on a multi-hydrogen-bond polyurethane polymer and a preparation method, and belongs to the technical field of solid-state batteries. The negative-electrode-free solid-state battery comprises a positive electrode, an electrolyte layer and a copper foil current collector, wherein a polyurethane polymer with multiple hydrogen bonds is introduced into the electrolyte layer. The polyurethane polymer with multiple hydrogen bonds forms a dynamic cross-linked hydrogen bond network through a plurality of hydrogen bond donors and hydrogen bond receptors contained in a molecular chain, and has an excellent self-repairing function. The polymer is introduced into an electrolyte layer, real-time protection and repair of an electrolyte-electrode interface are realized by utilizing the self-repairing characteristic of the polymer, generation and expansion of interface cracks are effectively inhibited, and a more uniform and stable electrolyte / copper foil interface is constructed. And the uniform interface can guide lithium to be uniformly deposited on the surface of the copper foil current collector, so that the growth of lithium dendrites and the generation of dead lithium are avoided, and the coulombic efficiency, the rate capability and the long cycle stability of the negative-electrode-free solid-state battery are remarkably improved.
