The invention provides an ethylene / alpha-olefin copolymer as well as a preparation method and application thereof. The molar percentage content of an alpha-olefin ternary sequence EXXXE measured by a nuclear magnetic resonance carbon spectrum in the ethylene / alpha-olefin copolymer is 4.5%-13%; wherein E represents an ethylene-based structural unit, and X represents an alpha-olefin-based structural unit. Through the special design of the intrinsic fine chain structure, the polymer has high cross-linking reaction activity, high cross-linking vulcanization reaction speed and high cross-linking degree, also has good melt flowability, can be widely applied to packaging materials of photovoltaic modules, and has wide application prospects. On the basis of not needing to regulate and control the components and the use amount of a cross-linking auxiliary agent in the cross-linking process and not depending on a cross-linking process, the processing speed and the adhesive film strength of the photovoltaic packaging material are remarkably improved, meanwhile, the use amount of the cross-linking auxiliary agent can be reduced, and the preparation method has important significance on cost reduction and efficiency improvement of a photovoltaic module.

This utility model belongs to the technical field of corrugated cardboard processing equipment, and in particular to a corrugated cardboard flattening device. A flattening roller for flattening the corrugated cardboard is arranged directly above the support roller. Three support rollers and three flattening rollers are provided, and each pair corresponds to one support roller. A geared motor for providing power is installed on the side of the frame. A pulley frame for power transmission is installed between the output shaft of the geared motor and the end of one of the support rollers. A pressure adjusting component is provided between the frame and the flattening roller. This component can be adjusted by telescoping to directly change the pressure of the flattening roller on the corrugated cardboard. The operator can adjust the flattening pressure in real time according to the thickness, flute type, and material hardness of the cardboard: for thicker, harder double / triple corrugated cardboard, the pressure can be increased to ensure a smooth surface; for thinner, easily deformable single / E-flute cardboard, the pressure can be reduced to avoid corrugation crushing.

This invention relates to the field of hydraulic press technology and discloses a hydraulic press device for producing metal trash cans, including a main body with four positioning rods fixedly connected to the top of the main body. When the arc-shaped plate continues to press the top of the can and rotates, it provides guiding friction to the can body. At this time, the metal area at the top of the can body is bent and shaped as the arc-shaped plate rotates. When the can body pushes the arc-shaped plate upwards, the arc-shaped plate pre-presses the metal at the top of the can body. Then, when the arc-shaped plate drives the metal of the can body to rotate and curl the edge, it enhances the curling force while reducing the likelihood of cracks appearing in the metal body during the curling process. By assisting in increasing the curling strength of the metal body, the arc-shaped plate further improves the integrity of the curling angle and increases the curling efficiency.

The present application relates to a hydraulic cylinder piston annular groove grooving device, and relates to the field of hydraulic cylinder piston rod processing technology equipment, including a base, a chuck, a drive motor, a heat sink, a cooling fan and a tool are arranged on the base, a heat dissipation cavity is arranged in the tool, a heat exchange cavity is arranged in the heat sink, a heat exchange tube is connected between the tool and the heat sink, a drive device is arranged in the heat exchange tube, the output shaft of the drive motor is coaxially fixedly connected to a first drive bevel gear, the rotating shaft of the cooling fan is coaxially fixedly connected to a first driven bevel gear, and the first drive bevel gear is meshed with the first driven bevel gear. When the speed of the drive motor increases, the heat dissipation capacity increases accordingly; when the speed of the drive motor decreases, the heat dissipation capacity decreases accordingly. The heat dissipation capacity can be automatically adjusted as the processing intensity changes, the structural strength of the tool is maintained, and the tool life is extended. The present application has the effect of reducing the temperature fluctuation amplitude of the tool during the grooving process.

The invention relates to a hydraulic oil cylinder piston annular groove slotting device, and relates to the field of hydraulic oil cylinder piston rod machining technical equipment.The hydraulic oil cylinder piston annular groove slotting device comprises a base, a chuck, a driving motor, a cooling fin, a cooling fan and a cutter are arranged on the base, a cooling cavity is formed in the cutter, a heat exchange cavity is formed in the cooling fin, and a heat exchange pipe is connected between the cutter and the cooling fin; a driving device is arranged in the heat exchange pipe, an output shaft of the driving motor is coaxially and fixedly connected with a first driving bevel gear, a rotating shaft of the cooling fan is coaxially and fixedly connected with a first driven bevel gear, and the first driving bevel gear is meshed with the first driven bevel gear. When the rotating speed of the driving motor is increased, the heat dissipation capability is improved; and when the rotating speed of the driving motor is reduced, the heat dissipation capability is reduced. The heat dissipation capacity can be automatically adjusted along with the change of machining strength, the structural strength of the cutter is kept, and the service life of the cutter is prolonged. The method has the effect of reducing the temperature fluctuation amplitude of the cutter in the grooving process.
