A method and a device for separately taking out a carton for packaging ceramic tiles belong to the field of packaging machinery and specifically relate to a method and a device for taking out a single carton. The method comprises the steps that: cartons are piled up in a carton storage bin the bottom of which is open, and the front ends of the cartons are bent downwards; then a carton separator is inserted between the bottom carton and an adjacent carton above the bottom carton; the carton separator is moved backwards to separate the bottom carton from the adjacent carton above the bottom carton; and the bottom carton drops down so as to completely separate a carton at a time. Most of the cartons in the carton storage bin are supported by carton brackets; the cartons which are not supported by the carton brackets are in level states due to own intensity; when a sucker sucks the bottom carton, the adjacent carton above the bottom carton does not bend along with the bottom carton, so that a gap with a certain included angle is generated between two adjacent cartons, and a separation head is smoothly inserted between two cartons to ensure that only one carton is sucked at a time.

The invention belongs to the field of daily necessities, and in particular relates to an anti-teardown thermos bottle, which comprises a shell, the lower end of which is slidably connected with a base movable in the vertical direction, a cavity is provided in the base, and a cavity runs through and is slidably connected with A support rod, the upper end of the support rod is fixedly connected with a load-bearing base, and a plurality of fixed rods are fixedly connected to the side wall of the load-bearing base. There are multiple strip-shaped airbags that can move in the vertical direction at the gap between the inner tank and the shell, and the shell is composed of multiple vertical reinforcing rods and a soft shell connected between adjacent reinforcing rods. Composition, the bar-shaped airbag is arranged between two adjacent reinforcing rods, and the part of the supporting rod between the base and the load-bearing seat is covered with a spring. The present invention utilizes the gravity of the thermos bottle to increase the adsorption force between the base and the desktop, making the thermos bottle difficult to slide and having high safety.

The invention relates to a preparation method for a stretch wrap film, which belongs to the technical field of packaging materials. According to the method, carbon atoms in carbon nanotubes are hybridized by adopting SP2, so that the carbon nanotubes have high modulus and high strength, the carbon nanotubes have good mechanical properties, the carbon nanotubes with good flexibility can be stretched, and therefore the composite material which is prepared by adding the carbon nanotubes can show good strength, elasticity, fatigue resistance and isotropy. Because silica sol is adopted to wrap titanium dioxide and the carbon nanotubes in the method, titanium dioxide and the carbon nanotubes can be uniformly distributed and cannot be easily agglomerated; because the wrapping material is added, the silica sol which is a stable disperse system for silica colloid particles in water can act along with nanoscale titanium dioxide, so that the chemical property of the wrapping material is stable; moreover, as a continuous body with a spatial reticular structure, the silica sol has a large specific surface area to firmly adsorb the carbon nanotubes, and thereby the tensile strength of the stretch wrap film is effectively increased.

The invention discloses a method for preparing a renewable anti-bacteria fiber for adsorbing heavy metal motes. The preparation method comprises the following steps: dissolving cellulose acetate in a specific solvent; adding a certain amount of polyhydroxyl benzoyl chloride and a basic catalyst to generate polyhydroxyl benzene acid cellulose acetate; filtrating to remove the basic catalyst and solid salt formed by by-product, chlorine hydride; filtrating the liquor by adopting an industrial frequently-used vacuum silk imitation method, and evaporating a solvent to prepare a functional artificial fiber. According to the method for preparing a functional cellulose acetate fiber, the heavy metal motes can be effectively removed by an air filtration material and the fiber has the anti-bacteria function and can be reused.

The invention discloses a light-transmittance carrier, and a packaging apparatus for an electroluminescent device. The packaging apparatus for the electroluminescent device comprises the light-transmittance carrier; the light-transmittance carrier comprises an adsorption surface which is used for being attached with an adsorption object, a negative pressure air gap which is used for being adsorbed with the adsorption object, and a negative pressure interface which is used for being connected with a negative pressure apparatus; the negative pressure interface is formed in the light-transmittance carrier; and the light-transmittance carrier also comprises an air flow channel which is used for being connected with the negative pressure air gap and the negative pressure interface. The light-transmittance carrier is matched with the adsorption effect of the negative pressure apparatus; the light-transmittance carrier is applied to the packaging apparatus for the electroluminescent device, so that the phenomena of edge warping and deformation of glass or a PET film substrate or a cover plate caused in the temperature rise and cooling processes in the craft process in the UV adhesive curing process of the electroluminescent device can be effectively avoided; and therefore, the surface of the dual-layer glass or the dual-layer PET film is more smooth, so that the cutting yield can be improved, the IC bonding yield can be increased, and the service life of the product can be prolonged.

The improved adjustable double-sided adhesive tape cutting and transferring unit for disposable diaper producing apparatus features its increased movable cutter frame with cutting roller, bottom roller and air sucking valve mechanism; the increased eccentric wheel mechanism on the bottom roller; and the improved air sucking valve with double air passage. The unit can ensure the coincident back and front positions of adhered double-sided adhesive tape, stable adsorption and transfer, firm adhesion and high production efficiency.

The invention provides a vacuum chuck. The vacuum chuck comprises a vacuum nozzle and a piston vacuumizing device; the piston vacuumizing device is connected with the vacuum nozzle through a check valve; and when air is exhausted through the vacuum nozzle by the piston vacuumizing device, the check valve prevents air from flowing back to the vacuum nozzle. The vacuum chuck can suck a wafer firmlywithout being externally connected with a vacuum system for vacuum supply, is convenient to use, can be applied to any occasion, and saves production cost.

The invention provides a small fan with a suction cup. According to the small fan with the suction cup, the suction cup is arranged at the bottom of the small fan, so that the small fan can be firmlysucked to an office table top, and people do not need to worry about knocking down the fan when working at ordinary times.
