The ricefield eel trapping device comprises a supporting rod, a plurality of strip-shaped rods are arranged on the peripheral side of the outer portion of the supporting rod in parallel, at least two annular bases are arranged from one end to the other end of the surface of the supporting rod, and the edges of the annular bases are rotationally connected with a plurality of elastic supporting rods inclining towards the same direction. The strip-shaped rods are rotationally connected with the tail ends of the elastic supporting rods correspondingly, when the supporting pipes move back and forth along the supporting rods, the strip-shaped rods are folded or unfolded towards the supporting pipes at the same time, and when the elastic supporting rods are approximately perpendicular to the axes of the supporting pipes, the ends of the supporting pipes and the supporting rods are fixed through positioning devices. When the monopterus albus collecting net is used, monopterus albus can enter the supporting net body from the first conical net, and then the monopterus albus can enter the collecting net body from the second conical net. According to the monopterus albus trapping device, the supporting net body is supported by the strip-shaped rods, so that the supporting net body can be always kept in an open state in water and cannot incline or deform.

The utility model relates to paper box sealing field especially relates to a paper box sealing folding device, including folding table, the top of folding table is provided with mounting bracket, and the top of mounting bracket is provided with hydraulic cylinder, and the output end of hydraulic cylinder is connected with connecting table through hydraulic rod, the bottom of connecting table is provided with mounting shaft, and the bottom of mounting shaft is rotatably installed with folding mechanism, and the folding mechanism is connected with mounting shaft as main guide bar, and the bottom end of main guide bar is provided with elastic hinge, and the tail end of main guide bar is connected with pressing rod through elastic hinge. In the utility model, first through the folding mechanism that folding table top mounting bracket bottom set can carry out sealing folding to paper box, and through the conveyance of conveying roller can guarantee that it will not be skew, and through the hydraulic rod of top and the electric telescopic rod of side edge can adjust the position of folding mechanism when facing different size paper box folding, convenient to fold different size paper box.

The utility model relates to the technical field of printing paper carding equipment, and discloses paper carding equipment for a printing machine, which comprises a printing machine body, a conveying table is fixedly mounted on one side, close to the lower end, of the printing machine body, and square carding blocks which are symmetrical in pairs are fixedly mounted at the upper end of the end of one side of the conveying table. The center of one side of each square carding block is rotationally provided with a double-screw rod, the outer side walls of the double-screw rods are rotationally provided with threaded sleeves in a pairwise symmetrical mode, and the lower ends of the threaded sleeves are fixedly provided with limiting clamping plates. The width between the two limiting clamping plates is flexibly adjusted so as to adapt to feeding of paper of different sizes, the side edges of the paper are limited through a progress channel formed by the limiting clamping plates, and meanwhile, the two pressing rotating rollers which are symmetrical to each other and can be adjusted in a rolling mode are arranged, so that warpage generated by the paper can be pressed when the paper is carded and moved.
