1.Hydraulic uncoiler-上海中吉机械有限公司官网

1) each decoiler The sprocket is driven by the hydraulic motor, and the main knot is driven by the sprocket, so that the steel coil rotates with the spindle,
2) to achieve the purpose of active unrolling . Both the base and frame of the decoiler adopt a rectangular tube welding structure, which fully guarantees the rigidity of the equipment.
3) Roll: four pieces Nesting (boots), two sizes of 508 and 610 are provided. When the 508 steel coil is switched to the 610 inner hole steel coil, four arc plates are installed on the original uncoiler to automatically hold the constant tension control;
4) Auxiliary support: in polyurethane During continuous line production, the steel plate butt joint should be minimized, so the load of the decoiler is higher. At the same time, in order to sag one end of the cantilever decoiler spindle to prevent the steel coil from deviating, the machine adopts additional auxiliary support to ensure that it can withstand 10 tons of the steel coil spindle. Will not deform.
The auxiliary support of this uncoiler adopts Fast hinge type, the operation is very convenient, in order to achieve fast-tracking board head-to-tail docking to perform non-stop production. In order to meet the requirement of rapid switching of steel plates in the state of small coils, this machine adopts V-shaped block auxiliary clamping to reduce the stroke of the oil cylinder and perform rapid coil change to achieve non-stop production.
All the above measures ensure that the steel coil is replaced The time can be completed in 45 seconds,
5) Transmission system: front and back The mandrel of the unwinding and unwinding machine is driven by the motor and the reducer to realize the active cutting of the steel plate. It can also be used for the recycling of the unprocessed plate; when the active cutting, it can maintain the synchronization with the production speed, and there is ultrasonic detection Control the unwinding speed to track the speed of the host, and the whole process is controlled by frequency conversion.
6) Center adjustment device: The center line shall prevail, 75mm on the left and right sides, plus a ruler and a stop. The center line of the coil is based on the center of the entire production line. There is an obvious mark ruler display. The adjustment of the coil center of the decoiler is realized by a hydraulic cylinder, which is convenient to adjust and easy to operate;
7) The pressing mechanism is passed The cylinder swings the pressing arm. When the air cylinder rises, the material pressing arm is released; when the air cylinder descends, the material pressing arm is pressed tightly. When actively uncoiling, the pressing arm must press the steel coil tightly.
8) Lifting trolley: lifting The trolley is driven by an oil motor to move the trolley along the guide rail. The lifting mechanism is a lifting platform with a hydraulic cylinder passing through the connecting rod to complete the loading and unloading actions. The lifting platform and the walking platform adopt a rectangular tube and steel plate mixed welding structure, and the appearance is beautiful.
