The utility model provides an adjustable air window for a coal mine, which belongs to the technical field of mine ventilation and comprises a frame body and a plurality of louvre blades, the louvre blades are respectively and uniformly arranged in a hollow cavity of the frame body through a rotating shaft, one end of the rotating shaft is provided with an adjusting gear, and the adjusting gear is meshed with an adjusting rack. The adjusting rack is connected with a sliding mechanism, a servo motor is arranged on one side of the frame body, the output end of the servo motor is connected with a transmission mechanism, and the transmission mechanism is connected with a rotating shaft. The transmission mechanism comprises a plum coupling, a corner device, a pin coupling and a speed reducer, the output end of the servo motor is connected with the speed reducer, the speed reducer is connected with the corner device through the pin coupling, and the corner device is connected with one end of the rotating shaft through the plum coupling. Through the design of the transmission mechanism and the sliding mechanism, the transmission efficiency can be effectively improved, accurate adjustment of the ventilation quantity is achieved, and safety, reliability, high efficiency and energy conservation are achieved.

The utility model discloses a kind of ceramic tile horizontal calibration installation auxiliary devices of self-adaptive adjustment, it is related to building engineering field.The utility model includes auxiliary device, ceramic tile, auxiliary device includes fixed rod, fixed rod lower side is fixedly connected with connecting bolt, connecting bolt outside is threadedly connected with nut, the lower side of nut is installed with connecting plate, the below of connecting bolt is connected with connecting rod, the lower side of connecting rod is installed with limit rod, by replacing limit plate, adjacent ceramic tile gap width is quickly matched, staggered layout further disperses single-point pressure, prevent ceramic tile deviation, rectangular friction block enhances the controllability of manual operation, guarantee the stability of adjustment under construction humid environment, the center integrated structure of limit rod and connecting rod eliminates assembly gap, ensure that pressure vertical transmission entire device is through mechanical linkage and realizes once installation completion horizontal calibration and gap control, reduce construction error rate and shorten construction period.

This utility model relates to the field of food traceability technology and discloses a coding device for food traceability, including a support plate 1. Two connecting plates are fixedly connected to one side of the support plate 1. A second support plate is fixedly connected to one end of each of the two connecting plates. A conveyor belt is installed between the connecting plates and the second support plate. A motor 1 is installed on one side of the second support plate. A fixing rod 1 is fixedly connected to the top of the support plate 1. The other end of the fixing rod 1 is fixedly connected to one side of the second support plate. An adjustment component is installed at the bottom of the fixing rod 1. A second fixing rod 2 is fixedly connected to the top of the first support plate. A moving component is installed in the middle of the second fixing rod 2. A dust removal component is provided on one side of the second support plate. In this utility model, the motor 2 drives the bidirectional threaded rod to rotate, thereby driving the moving rods on both sides to move. The limiting plate adjusts its position with the moving rods, adjusting the product position and improving the efficiency of coding.
