The invention discloses a high-energy-storage-density anti-ferroelectric ceramic material and a preparation method thereof. The general chemical formula is (Pb < 0.98 > La < 0.02 >) (Zr < 0.7 > Sn < 0.3 >) < 0.995 > O < 3-x > wt% Al < 2 > O < 3 >, x is smaller than or equal to 0.7, Al2O3 is a sheet-shaped template, the Al2O3 sheet-shaped template is directionally arranged in the anti-ferroelectric ceramic material along the same direction through a tape casting preparation process, and the Al2O3 sheet-shaped template is regulated to be parallel to a test electrode through polishing and metal spraying on the upper surface and the lower surface parallel to the Al2O3 sheet-shaped template. According to the anti-ferroelectric ceramic material, the Al2O3 sheet-shaped template and the test electrode are arranged in parallel, so that the Al2O3 sheet-shaped template effectively disperses an applied electric field in the whole anti-ferroelectric ceramic material matrix, non-uniform distribution of a local electric field is reduced, improvement of the breakdown strength of the anti-ferroelectric ceramic material is facilitated, and the energy storage density of the anti-ferroelectric ceramic material is further improved.

The utility model relates to the technical field of rice noodle production, in particular to a double-screw automatic filling machine for nutritional rice noodle production, which comprises a support and an extension device, a thread device is arranged on the surface of the support, a material hopper is arranged at one end of the thread device, and a discharge pipe is arranged at one end of the thread device far away from the material hopper. A motor is arranged on the surface of the thread device, the extending device is arranged on the surface of the discharging pipe, the extending device comprises a first connector and a telescopic pipe, and the first connector is connected with the surface of the discharging pipe in a sleeving mode. According to the utility model, the extension device is arranged, so that the discharge pipe is effectively extended, the effect of extending the discharge pipe is achieved, and the problem that raw materials are easy to splash and scatter around a material receiving position due to a certain interval between the discharge pipe and the material receiving position when the equipment is used and the raw materials are conveyed and discharged is solved. The environment pollution of the equipment is avoided, and the practicability of the equipment is improved.

The utility model discloses a yarn bobbin fixing buckle structure of a wrap yarn machine, which comprises a pipe body, the left side and the right side of the pipe body are respectively closed, round blocks are connected to the left side and the right side of the pipe body in a penetrating manner, a rotating rod is sleeved in the pipe body, a through hole matched with the rotating rod is formed in each round block, and the through hole is communicated with the rotating rod. The left end and the right end of the rotating rod penetrate through the penetrating holes respectively and extend out of the pipe body, round pipes are arranged on the left side and the right side of the pipe body respectively, the rotating rod is sleeved with the round pipes through bearings, and the positions, close to the left side and the right side, of the rotating rod are sleeved with oval rings respectively. According to the technical scheme, through mutual cooperation of a rotating rod, an oval ring, a right trapezoid block, a second contact wheel and other components, the device can be effectively extended, so that the device can adapt to fixation of bobbins with different hole diameters, the application range and the use efficiency of the device are improved, the right side of an inserting rod can be driven to move while extension is conducted, and the practicability is high. Therefore, the multi-directional clamping can be realized, and the stability is improved.
