The first process in the production line of shear machine is to open roll, which will use the Decoiler Device. The Decoiler Device is used to support the steel coil, rotary steel coil. With the requirement of speed and plate quality, the type has gradually developed to the expansion drum type decoiler device. Decoiler device is equipped with driving mechanism. The rolling of the rolling material is driven by the driving roll. In order to deploy the roll bearing material and enter the printing device continuously and stably, the lateral adjustment mechanism and tension control mechanism are provided on the open and rewinding devices for controlling the lateral positioning and tension of the tape. In addition, some flexible printing presses using belt and material roll surface friction to produce the material roll braking force. The installation of material coil is divided into two types: core axis type and no core axis type. Due to the cone head clamping is easy to damage the edge of the coil, so now many flexible printing presses use the expansion core shaft clamp, expansion shaft can be divided into mechanical and pneumatic types. The Decoiler Device composed of guide screw, nuts, and expansion，rolling system and expansion drum, pressing roller and supporting device.

When the conveyor device feeding the material into the Decoiler Device, the hydraulic decoiler expands the claw plate to tighten the steel coil, and the rise and contraction should be cooperate with the roll to avoid break the car or the decoiler shaft.

Through the hand wheel rotation and the bidirectional wire rod, the steel coil is sent to the cutting bed smoothly by the feeding roller. If the customized model has a leveling roller must be adjusted according to the thickness of the processing plate. The guiding table should be able to guide normally. The guiding table is appropriate to touch the side of the plate, the plate is not touched, will make the ruler is not accurate, the plate is too large, will make the plate edge damage, pay attention to the model of no side guide according to different models. The measuring wheel measures the length and speed of the plate, to determine that the measuring wheel rotation is flexible.

It is equipped with gear and shaft box, leveler device, roller wheel, back roller, clip wheel, and feed guide plate. The leveler device’s main device power is DC 250KW DC motor. The leveler device flat wheel lift is gear reduction motor with brake. The leveler device system control is fully synchronized with the foot feed wheel of the shear bed. It is automatic brake system.

Basic capacity: 6mm~25mm T x 2050mmW hot-rolled steel roll and leveling feeding, etc. The maximum line speed is 40 meters.

The Pinching Device is used for pinching to convey the rolled steel strip. The Pinching Device is composed of the lower mounting frame and the upper mounting frame. The upper mounting frame is located directly above the lower mounting frame. The upper end of the lower mounting frame is fixed with a lower support frame. The upper end of the lower support frame is equipped with a power wheel. The power wheel is connected to the lower support frame, the drive motor is provided on one side of the power wheel, The lower end of the lower support frame is fixed with a lower connecting rod. The other end of the lower connecting rod is fixed and mounted. Need to clean the tape before pinching. Remove the iron scraps, beads, or oil stains from the steel strip surface. Prevent wear of the power and pressing wheels during pinching. Extend the service life of power and pressing wheels. At the same time preventing water droplets or oil stains can avoid skid phenomenon in the process of delivery, and can ensure the pinching effect.

Double Slitter Device is also known as double-blade vertical shear line, double-blade longitudinal cutting machine, and double-blade strip machine, is one kind of metal cutting equipment. The Double Slitter Device is suitable for the longitudinal cutting of the metal strip, and recoils the narrow strip into a roll.

The Double Slitter Device is equipped with upper and lower knife frame and smooth system and other components. The Double Slitter Device are arranged parallel to start the stop working system. The motor are equipped with a safety tooth coupling to ensure the safe use of the Double Slitter Device. The motor use external ventilation type DC motor and equipped with speed measuring motor that used to measure the speed of the DC motor.

The high-speed precision rotary shear device is composed of rotary shear box components (lower seat, middle and lower seat, middle seat, middle and upper seat, upper cover, transmission shaft, inclined gear set, upper and lower knife frame, knife body and smooth system) and other components. The reverse knife holder is equipped with a single blade, and two knife shafts are arranged parallel to start the stop working system. After the first shear cycle, the motor drives down the knife shaft by the reducer, and the upper and lower knife shaft is driven by the gear. The lower knife shaft is connected to the rotating device. The motor uses external ventilation type DC motor, and is equipped with speed measuring motor, used to measure the speed of the DC motor.

The device is composed of transmission device, shear seat and rotary shear box assembly and other components.
