The invention discloses an impact-proof automobile air bag rigidity detection device. The impact-proof automobile air bag rigidity detection device comprises an L-shaped operation bench (1). Two fixed blocks are arranged on a vertical surface of the operation bench (1) in an up-down manner. The fixed blocks include an upper fixed block (3) and a lower fixed block (4). A smooth through hole penetrating a screw (5) is formed in the upper fixed block (3). A circular groove for accommodating the bottom end of the screw (5) is formed in the upper surface of the lower fixed block (4). The screw (5) is in threaded connection with a movable block (6). The movable block (6) is connected with a horizontal upper extruding plate (8) through an upright column (7). A plurality of grooves (15) for accommodating heavy objects are formed in the upper surface of the upper extruding plate (8). The impact-proof automobile air bag rigidity detection device provided by the invention is high in automatic degree and is real and reliable in detection result, the upper extruding plat has an impact-proof function, and the universality is high.

The invention discloses a 3D printer with a rotating and autonomous coloring structure, which includes a main body shell, a coloring ring, a braking area, a driving gear and a movable base. The operating table is fixed, a control rod is arranged above the telescopic rod, a chute is arranged inside the coloring ring, a coloring nozzle is installed inside the chute, a fixed rotating shaft is arranged at the inner lower end of the braking area, and a fixed rotating shaft is installed above the fixed rotating shaft. There are vertically moving crawlers. Compared with the existing ordinary 3D printers, the 3D printer with a rotating and autonomous coloring structure has as few internal structures as possible while ensuring its printing performance, effectively reducing the production and use costs of the equipment, and discarding The original method of production relying on the basic color of the material can achieve simultaneous or independent coloring after processing, which greatly improves the scope of application of the entire equipment.

This application relates to a curing room for recycled concrete test blocks, which includes a curing room with an open side and a curing door covered on the opening. The inner wall of the curing room is provided with a humidifying component. For the maintenance boards arranged horizontally, the maintenance room is provided with a lifting assembly that drives several maintenance boards to move up and down sequentially, and the maintenance room is provided with a supporting assembly that fixes the maintenance boards moved to the designated positions. In the present application, the lifting component is driven to move downwards to reduce the height of the curing plate, which is convenient for staff to put and take concrete test blocks on the curing plate, and reduces the workload of the staff.

The present invention relates to the technical field of paper pulp whiteness detection during a pulping papermaking process, more particularly to a wet pulp sample placement apparatus and a control method thereof. The wet pulp sample placement apparatus comprises a first motor, a sliding track connected with the first motor, and a sliding block arranged on the sliding track, wherein the upper end portion and the lower end portion of the sliding track are respectively provided with an upper position limitation switch and a lower position limitation switch. The wet pulp sample placement apparatus further comprises a second motor, a rotation shaft and a tray, wherein the second motor is fixed on the sliding block, one end of the rotation shaft is connected with the second motor, the other end is connected with the tray, and the second motor is provided for driving the tray to rotate through the rotation shaft. The wet pulp sample placement apparatus further comprises a single-chip computer arranged inside the wet pulp sample placement apparatus, wherein the single-chip computer is respectively and electrically connected with the first motor, the second motor, the upper position limitation switch and the lower position limitation switch. The wet pulp sample placement apparatus has the following characteristics that: the structure is simple, up and down displacement can be achieved, 360 DEG rotation can be achieved, and the apparatus can be adopted to replace manual rotation of a sample requiring detection, such that the whiteness detection result of the sample is accurate.
