This utility model discloses a double-belt double-sided inkjet camera, including a conveying mechanism. The conveying mechanism includes a feeding roller, a receiving roller, a guide roller group, and a double transport platform. The double transport platform includes a first transport platform and a second transport platform. The first transport platform is located above the second transport platform and the transport directions are opposite. A first inkjet carriage is arranged above the first transport platform, and a second inkjet carriage is arranged between the first transport platform and the second transport platform. This utility model, through the conveying mechanism and the cooperation of the first and second inkjet carriages, enables one-time inkjet printing of double-sided materials, improving production efficiency. The camera identifies the position marker group and transmits the position information to the second inkjet carriage through the system. The second inkjet carriage then adjusts the inkjet printing according to the position of the already printed pattern, aligning the pattern printed on both sides of the inkjet material.

The utility model relates to the technical field of mechanical assembly, in particular to a coupler aligning and centering device for a linear electric cylinder driving system. Comprising a shafting supporting assembly, a linear electric cylinder shell and a tool, the shafting supporting assembly is coaxially and fixedly installed in the linear electric cylinder shell, the shafting supporting assembly is positioned through a shaft shoulder of the linear electric cylinder shell, and a pin shaft of the tool is inserted into a hole of a coupler of the shafting supporting assembly. The fastening bolt is locked from the kidney-shaped hole in the side edge of the linear electric cylinder shell, and then the coupler is locked to the tool pin shaft. The shafting supporting assembly comprises a coupler, a connecting bolt, a shaft sleeve, a rolling bearing and a locking nut, the shaft sleeve is fixedly installed outside the coupler through the connecting bolt, one end of the shaft sleeve is sleeved with the rolling bearing, and the other end of the shaft sleeve is fixedly provided with the locking nut. The coaxiality of the rotating centers of the motor shaft, the coupler and the linear electric cylinder shell can be effectively guaranteed, and the assembly precision is greatly improved.

The utility model discloses a transformer oil tank structure, and relates to the technical field of power equipment. The top of the oil tank body is fixedly provided with a transformer top plate through bolts; the bottom of the transformer top plate is fixedly provided with a pressing frame; the bottom of the transformer top plate is provided with a sealing groove; the bottom of the transformer top plate is fixedly provided with a transformer body; t-shaped sliding grooves are formed in the inner sides of the oil tank body, limiting rods are fixedly installed on the inner bottom faces of the T-shaped sliding grooves, four connecting limiting assemblies used for improving the installation efficiency are symmetrically arranged in the oil tank body, the T-shaped sliding grooves are used in cooperation with the connecting limiting assemblies, a sealing assembly is arranged in the oil tank body, and the pressing frame is used in cooperation with the sealing assembly. By arranging the connecting limiting assembly, the problem that a transformer top plate mounting hole and an oil tank screw hole are difficult to align during mounting is solved, the mounting efficiency is improved, and the sealing assembly prevents oil liquid in the oil tank from leaking.
