The utility model discloses a material conveying turning structure of an aluminum material extruding machine, which relates to the field of profile processing, and adopts the technical scheme that the material conveying turning structure comprises a base and a baffle plate positioned on the top surface of one side of the base, the top surface of the base is connected with a speed brake in a sliding manner, one side of the speed brake close to the baffle plate is fixedly connected with a sliding rod, and magnetic blocks are linearly arrayed on the sliding rod; the baffle is fixedly connected with a copper ring, the sliding rod penetrates through the copper ring, and the magnetic block can penetrate through the copper ring. According to the utility model, the speed reducing plate abuts against the raw material and pushes the sliding rod to slide relative to the copper ring, when the magnet passes through the copper ring, the magnet is subjected to resistance based on electromagnetic induction and Lenz's law, so that the movement of the speed reducing plate and the raw material is slowed down, the kinetic energy is smaller when the raw material is contacted with the baffle plate, and the higher the raw material rolling speed is, the more obvious the speed reducing effect is; the surface of the raw material is prevented from generating flaws to influence the quality of the aluminum profile.

This invention relates to a spoiler device for automotive wind tunnel testing. The spoiler device is installed in an automotive wind tunnel testing apparatus, which includes a wheel rotation unit and a moving belt unit. The wheel rotation unit includes a working belt and a wheel rotation unit chamber. The working belt is installed at one end of the wheel rotation unit chamber, and a gap exists between the working belt and the wheel rotation unit chamber. The spoiler device includes a spoiler installed within the gap between the working belt and the wheel rotation unit chamber. Compared with existing technologies, this invention has advantages such as reducing the influence of the aerodynamic characteristics of the wheel rotation unit on the surrounding flow field by installing a spoiler between the working belt and the wheel rotation unit chamber, thereby reducing aerodynamic drag errors during testing; the spoiler can be a strip plate, a brush, or an air pipe, adapting to the needs of different wheel rotation unit rotation speeds and shapes.

This utility model relates to a labyrinth-type anechoic return air chamber suitable for HVAC systems, comprising: an anechoic chamber with an air inlet and an air outlet; multiple sound-absorbing baffles are arranged on the inner wall of the anechoic chamber, and the multiple sound-absorbing baffles are staggered to form a labyrinth channel for airflow; the air inlet and the air outlet are respectively connected to the two ends of the labyrinth channel; wherein, an arc-shaped air guide plate connected to the inner wall of the anechoic chamber is provided at each corner of the labyrinth channel. This application uses multiple sound-absorbing baffles in the anechoic chamber to form a labyrinth channel. The tortuous path of the labyrinth channel causes noise waves to be reflected multiple times, thereby effectively reducing noise. Furthermore, the longer anechoic path of the labyrinth channel has a better noise reduction effect and a deceleration effect on the airflow. By setting the arc-shaped air guide plate, the airflow smoothly turns, reducing airflow pressure loss and reducing eddies generated at the turns of the labyrinth channel, thus reducing the noise generated by eddies and ensuring the noise reduction effect.

This invention relates to a packaging box printing apparatus, specifically to the field of packaging box printing technology. It includes an offset printing unit, a secondary printing unit, and a connecting device, arranged sequentially from back to front. The offset printing unit includes an offset unloading conveyor belt, the secondary printing unit includes a secondary printing drive belt, and the connecting device includes a diversion mechanism and multiple transfer conveyors. One end of the diversion mechanism connects to the offset unloading conveyor belt, and the other end connects to each of the transfer conveyors. Each transfer conveyor connects to the secondary printing drive belt of a secondary printing unit. This application utilizes a connecting device to link the offset printing unit and the secondary printing unit, merging the offset printing and inkjet printing processes together. This eliminates the cumbersome operation of unloading, transferring, and reloading after offset printing, thus improving production efficiency.
