Chain wheel transmission guide mechanism for use in condom production
A chain wheel transmission guide mechanism for use in condom production having a rack and a mold frame. The rack is provided with a chain wheel assembly and an auxiliary rail assembly arranged in parallel with a chain of the chain wheel assembly. The auxiliary rail assembly has an upper load bearing guide rail and a lower limiting guide rail respectively disposed on the top and bottom of the rack. The chain wheel assembly has a chain wheel and a chain connected to the mold frame, and the mold frame is movably and cooperatively connected to an auxiliary rail assembly through a sliding part.
Fixing assembly for mounting UV lamps, curing device having the same, and curing method using the same
A fixing assembly for mounting UV lamps includes a base, a first gear and a plurality of mounting modules. The first gear is arranged on one side of the base; the mounting modules are arranged around the first gear. The mounting module includes a first driving assembly, a second driving assembly and a support frame. The first driving assembly is used to drive the second driving assembly and the support frame to move circumferentially around the first gear in a considerably horizontal plane, and the second driving component is used to drive the support to move back in a considerably vertical direction. The support frame is used for mounting UV lamp. The flexibility of the fixing assembly is improved. The UV lamp may comprehensively irradiate and cure the photosensitive adhesive.
COMPOSITE LAMINATE HEATING TOOL AND METHOD FOR FORMING SAME
A composite laminate heating tool broadly comprising a substructure, a facesheet, and number of expansion joints. The substructure supports the facesheet but does not need to have the same or a similar CTE as the facesheet because the facesheet is free to expand relative to the substructure. The expansion joints provide an interface between the facesheet and the substructure so that the facesheet can thermally expand relative to the substructure while being fully supported by the substructure. Each expansion joint includes a guide attached to the substructure and a support member translatable relative to the guide and aligned radially from a centroid or center of expansion of the facesheet so as to have a single degree of freedom.
Photosensitive resin composition for forming cell culture substrate
A photosensitive resin composition for cell culture substrates that enables the low-cost manufacture of a cell culture substrate, that can easily form patterns of various shapes when providing a pattern on the surface of a cell culture substrate, has low cytotoxicity, and that can form a cell culture substrate; a cell culture substrate that is formed using the photosensitive resin composition; and a cell culture substrate manufacturing method that uses the photosensitive resin composition. The photosensitive resin composition includes a photopolymerizable monomer and a photopolymerization initiator. The photopolymerizable monomer contains a defined amount of a polyfunctional monomer that is at least trifunctional, and the content of the photopolymerization initiator is within a prescribed range.
Molding equipment of composite material and molding method of composite material
According to one implementation, a molding equipment of a composite material includes a vessel, a decompression system and a heating medium supply system. The vessel houses a molding target sealed by a sealing object. The decompression system performs bending forming of the molding target and pressurization on the molding target after the bending forming by decompressing a region surrounded by the sealing object in the vessel. The heating medium supply system supplies a heating medium into the vessel. The heating medium is supplied for the bending forming, and heating and curing of the molding target under the pressurization.
