The existence of the three-dimensional porous graphite skeleton improves the energy conversion efficiency and heat transfer uniformity, and multiple phase change energy storage units are assembled together to form an energy storage device, which is expected to be applied to peak load shifting, waste heat recycling and reuse and periodic new energy rapid storage and release.

The utility model discloses an inverted push rod mechanism of a packaging machine supply line, which comprises a conveying rack, a bearing track mounted on the conveying rack and used for bearing and guiding products, a transmission chain belt mounted inside the conveying rack, and a first push rod and a second push rod alternately rotating on one side of the transmission chain belt at intervals. And open grooves matched with the first push rod and the second push rod are formed in the top of the bearing rail, and the guide assembly is installed on the conveying rack, used for guiding and limiting the first push rod and the second push rod and further used for changing the working state of the second push rod. The transmission chain belt, the first push rod, the second push rod and the guide assembly are used in a matched mode, the length of the first guide rod on the first push rod is different from that of the second guide rod on the second push rod, when the switch unit is opened or closed, the working state of the second push rod can be adjusted through the second guide rod, and the number of conveyed products can be changed.

The application discloses a low-rigidity thin-wall gear ring end face grinding tool, which comprises an electric permanent magnetic chuck, three fine-tuning precision lifting platforms, three arc-shaped clamping blocks and a flatness measuring device, the three fine-tuning precision lifting platforms and the three arc-shaped clamping blocks are alternately arranged on the surface of the electric permanent magnetic chuck with equal intervals. The application changes the traditional end face adsorption clamping into gear ring cylindrical surface clamping, changes the clamping force from axial to radial, and transfers the error to the non-sensitive direction of machining, so that the gear ring positioning can be rapidly realized, and the machining efficiency of the gear ring is improved; the end face will not be deformed and the error reflection problem will not occur under the large magnetic force, and the clamping force will not affect the precision of the end face grinding process. The electric permanent magnetic chuck is adopted for clamping, so that the deformation problem of the clamping position in the traditional clamping mode is avoided, and the end face grinding production efficiency is improved.

This utility model discloses a modular stator structure, characterized by comprising several stator core blocks arranged in an I-shape, each composed of a yoke and stator teeth, forming an integral stator core. Stator slots are formed between adjacent stator core blocks, and the stator teeth are T-shaped, with slot openings communicating with the slots between adjacent teeth. The structure also includes a filler for changing the number of stator slots without altering the stator core diameter. This utility model utilizes several stator core blocks assembled into an integral stator core, with each block composed of a yoke and stator teeth. The entire stator core is modularly assembled, which effectively improves utilization, saves silicon steel material, and reduces costs when pressing silicon steel sheets using a press.

The utility model relates to material turning baffle technical field discloses a kind of coarse mill baffle material turning device, including first baffle, second baffle and third baffle, second baffle and third baffle are sequentially spliced in the front end of first baffle, and form ladder shape, still be provided with the long screw rod that is through the first baffle, second baffle and third baffle are penetrated, the end of long screw rod is fixed with the abutment plate that is attached to the surface of third baffle, and the outer ring of other end of long screw rod is connected with the nut that is abutted on the surface of first baffle by screwing, the bottom both sides of first baffle, second baffle and third baffle are provided with arc edge.The utility model technical scheme is changed into three-stage ladder baffle by the original baffle, utilizes roller rotation power and baffle left and right propulsion power, so that ceramic raw materials are automatically turned when being pushed by reaction force through ladder position, realize automatic material turning action, reduce worker's labor intensity, effectively avoid the phenomenon that material turning times are not enough, and improve material turning efficiency.
