  • Patent number: 11780119
    Abstract: A pressurizing pre-impregnating die head for a fiber reinforced plastic sheet machine is provided. The die head includes a body; at least one group of fiber channels arranged in a longitudinal hole-through manner in a middle of the body, and a fiber yarn conveyed in the fiber channel. The body includes a feeding port and discharging ports, which communicate with each other. The discharging ports are located in outer sides of the fiber channel. Thermoplastic base materials in a molten state are paved on two sides of the fiber yarn. The thermoplastic base materials may be paved on surfaces of the two sides of the fiber yarn when being extruded.

  • Patent number: 11454638
    Abstract: A sample rack transport apparatus for transporting a sample rack to a sample analyser, comprising: a bidirectional transmission track for bidirectionally transmitting a sample rack without passing through the sample analyser; a feed channel in parallel with the bidirectional transmission track, wherein the sample rack may be delivered from the bidirectional transmission track to the feed channel and to the sample analyser; an unloading cache region located between the bidirectional transmission track and the feed channel, the unloading cache region being used for storing the sample tack; and an unloading mechanism for delivering the sample rack in the feed channel to the unloading cache region for storage, or delivering the sample rack stored in the unloading cache region to the bidirectional transmission track. Also provided are a sample analysis device and a sample analysis system using the sample rack transport apparatus.
