Abstract: A device for manufacturing a storage container by integrally winding multiple bundles of fibers in a double-layer spiral circumferential direction. The device includes a rotary drive unit and two radial slide drive units provided at two sides of the rotary drive unit, each of the two radial slide drive units is provided with several spiral winding guide wire tubes in a circumferential array and drives the spiral winding guide wire tubes to perform a radial telescopic movement, the rotary drive unit drives the spiral winding guide wire tubes on the two radial slide drive units to perform a rotation movement, the rotary drive unit is connected to the two radial slide drive units by means of brackets, and a rack plate is connected to one side of each of the two radial slide drive units away from the rotary drive unit.

Abstract: A device for continuously applying a transverse tension in an annealing process of an ultra-thin strip, including an unfolding and receiving mechanism for unwinding and winding the strip and an orthopedic mechanism for correcting the strip including an annealing furnace, and two orthopedic assemblies fixedly arranged inside the annealing furnace; the two orthopedic assemblies are symmetrically arranged on both sides of the strip, are parallel to an advancing direction of the strip and correspond to side edges of the strip, and include annular guide rails; each annular guide rail is fixedly connected with the annealing furnace and is slidably connected with an orthopedic part; the orthopedic part corresponds to each side edge of the strip, and each annular guide rail is internally provided with a driving part; the driving part is in transmission connection with the orthopedic part, and the orthopedic part is communicated with an air source part.

Abstract: The invention discloses a traceability system for pesticide residues, the main points of the technical scheme: the traceability system for pesticide residues, comprising the following steps; step 1, collecting the basic properties of a variety of pesticides commonly used in crops; step 2, collecting the degradation properties of pesticides in many different types of soils; step 3, collecting the rainfall, irrigation conditions and other agricultural operation factors; step 4, predicting the risk of pesticide residues on the surface of the soil after use, and speculating on the transfer pollution of pesticides to crops; step 5, predicting the pesticide residues available to leach into groundwater after pesticide use; step 6, predicting the pesticide residues available to leach into surface water after pesticide use.
