The utility model belongs to the field of ampoule bottle production, particularly relates to an ampoule bottle up-and-down turnover mechanism, and provides the following scheme aiming at the problems that frequent shutdown adjustment is needed, the manual intervention cost is high and secondary pollution is easily caused in the production process due to the fact that an existing mechanism cannot realize continuous and automatic turnover of row ampoule bottles, the ampoule bottle up-and-down turnover mechanism comprises a fixed frame, two connecting frames are symmetrically and fixedly arranged on one side of the fixing frame, and a motor is fixedly arranged at the top of the fixing frame; the fixing frame and the two connecting frames are provided with overturning assemblies, and the overturning assemblies are used for overturning and conveying the ampoule bottles. According to the utility model, through the arrangement of the overturning assembly, the automatic up-and-down overturning function of the row ampoule bottles in the connection transition of production steps is realized, so that the process requirements of subsequent detection and packaging links are effectively met, and the continuity and the automation degree of a production line are also remarkably improved; meanwhile, pollution risks and efficiency bottlenecks possibly caused by manual overturning are avoided.

This invention relates to the field of metal wire processing technology and discloses a forming device for tin wire processing, including a stabilizing component. The stabilizing component includes a guide plate, with stabilizing side plates fixed at both ends of the guide plate. A drive component for providing a power source is installed at one end of the stabilizing component. The drive component includes a motor fixed to the top of one end of the guide plate and a power rod rotatably connected to the two stabilizing side plates. A power transmission mechanism connects the motor and the power rod. By sliding two sets of independent feeding components on the guide plate, and the transmission component at its bottom can be moved along the power rod, the operator can quickly change the distance between the two sets of components by pushing either set of feeding components when the machine is stopped. This distance directly determines the single feeding length of the tin wire, thereby achieving stepless and rapid adjustment of the batch cutting length without replacing any parts, greatly improving the adaptability of the equipment to different specifications of products and the efficiency of production changeover.

The utility model discloses a cam belt tensioning mechanism and an amphibious vehicle. The cam belt tensioning mechanism comprises a mounting base, an adjusting bolt and a sliding bolt. A cam is arranged on the adjusting bolt, a pressing wheel is arranged on the sliding bolt, and tensioning adjustment of the transmission belt is achieved through rotation of the cam. The installation base is of a U-shaped structure and is provided with a sliding groove for the sliding bolt to move, and the adjusting bolt is fixed through the special-shaped hole and the adjusting nut. And the cam adopts an asymmetric shaft section design, and pushes the pressing wheel to continuously adjust the tension force during rotation. In a further optimized scheme, a rotating sleeve shaft is additionally arranged on the outer side of the cam, and friction is reduced. The mechanism is simple in structure, accurate in adjustment, suitable for tensioning control over the vehicle transmission belt, and particularly suitable for amphibious vehicles.
