The invention provides a one-way door with plane door leaves and relates to a plate-shaped one-way revolving door capable of being opened in the positive direction and being closed in the reverse direction. The one-way door mainly solves that problem that the gap between the secondary door and the main door of the known plate-shaped one-way door cannot completely block reverse walking of pedestrian and the problems that one end of a folding type secondary door is directly fixed on a connecting rod, a crank connecting rod and a folding door are hinged unstably, the folding secondary door has great inertia during operation, and vibration and noise cannot be overcome. The one-way door comprises three main doors and a secondary door, wherein the three main doors are fixed on a main shaft; the secondary door is connected with the main shaft through a crank connecting rod mechanism; the top of the main shaft is connected with a driving gear of a speed reducer through a key. The one-way door is characterized in that an output shaft of the speed reducer is connected with a pulley through the crank connecting rod mechanism; the pulley is mounted on a rail at the upper end of a door body; the lower part of the pulley is connected with an arc-shaped secondary door edge of the secondary door; the other end of the secondary door is hinged with a secondary door winding drum; a torsional spring is fixed at the end part of the secondary door winding drum; the other end of the torsional spring is fixed on a torsional spring fixing shaft; the upper end of the pulley is connected with a balance belt wheel through a balance belt; the balance belt wheel is fixedly connected to a wheel shaft; one end of the wheel shaft is fixedly connected to the door body through the a balance torsional spring. In the rotating process of the main doors, one main door and the secondary door are contacted all the time and maintain a small gap, so pedestrian only can walk in one way. The one-way door is reasonable and compact in structure, and has a good effect and operates stably through repeated tests.

The invention discloses an assistance mechanism for a bottom seaming machine of a woven bag, comprising a stander, wherein a first ring-shaped conveyor belt is arranged on the stander, the stander is provided with an edge coiling device at the outer side of the first conveyor belt, the stander is provided with a synchronous conveying mechanism at the lower side of the edge coiling device, the conveying speed and the conveying direction of the synchronous conveying mechanism are matched with those of the first conveyor belt. The assistance mechanism has the beneficial effects that the conveying speed lost by coiling the edge at the bottom of the woven bag is effectively compensated, so that the woven bag is tidy in edge coiling, and good in sewing quality, the wrinkles can be avoided when the woven bag is conveyed, the sewing speed of the bottom seaming machine can be improved in multiples, and the original quality bottleneck of the woven bag can be broken through, so that about sixty woven bags can be seamed pre minute; and the bottom seaming machine is smooth to run, so that the number of the production line operator can be reduced from four to one, therefore, the assistance mechanism has considerable economic benefit in the current market that the labor cost is constantly improved.

The invention belongs to the technical field of rail transit, and particularly relates to an intelligent rail vehicle automatic catering trolley. The catering trolley comprises a trolley frame and wheels, and further comprises condensation plates, supporting columns, first shafts, placement boxes, first control units and condensation units. The condensation units and the first control units are arranged, and the first control units and the condensation units are matched with each other, so that on the one hand, the freshness of beverages is improved, the beverages are not likely to go bad, andtherefore the drinking taste of beverages is improved; on the other hand, adjustment can be conducted according to actual needs of beverages, so that the beverages are evenly frozen, and the beveragerefrigerating effect is improved; meanwhile, in the process that the placement boxes move downwards, first air bags are extruded by the placement boxes, the first air bags blow out cold air, and thecold air directly acts on the beverages through first holes, so that the beverage refrigerating efficiency is improved.
