Function:  The uncoiling part is to drive the blade expansion through the screw rod, fix the coil to the blade of the spindle of the frame, and limit the movement or spread of the coil. Change the material from the arc state of the material coil to the flat state output of de-stress

Frame:   The frame is mainly welded by steel plate, and the welding surface is polished. The box is welded and annealed to remove stress.

Tension Part: Adopts hand-operated drive connecting rod to move, expand the blade fixed material roll. Three groups of large blades are designed, the blade radians are consistent with the inner diameter of the material, the blade surface is treated by hard plating, smooth and wear-resistant, and the material will not be damaged during use. One of the blades is inlaid with a positioning ruler, which can be referred to the positioning.

Block A Frame:Fast change locking structure is used in A frame, the replacement is quick and firm, the locking square is consistent with the blade surface, and the blade is not damaged


Press Arm:The automatic cylinder drive is used to open and close, which can press the material and prevent the material from loose after removing the belt. During the automatic operation, the press wheel will automatically adjust the speed with the change of the material diameter. In order to achieve the linear speed matching between the press wheel and the coil to prevent the coil from spreading. Compressor wheel surface for PU materials, do not hurt the surface of the material.
Main Parts:The main parts such as main board, feeding slide seat and so on are machined by CNC machining center to ensure the consistency of the two parts size, and the machining parts have strict quality control procedures.

Roller Part:The Straightening rollers are arranged as upper 3 and lower 4, and the feeding rollers are arranged as upper and lower 1, all of which are made of high carbon chromium steel. After tempering, lathe processing, high frequency quenching, grinding, hard chromium plating, re-grinding. Surface hardness HRC58~62, chromium plating thickness one side 0.05 mm.

Straightening Adjustment: Adopt precision reducer to adjust the angle of leveling roller and display the position of roller by scale.

Power Part: Adopts Ac motor with reducer drive, frequency conversion governor speed regulation; then through the chain drive to the roller rotation.

Transmission Part: The transmission gear is installed on one side of the roller, all gears are nitriding and hard grinding. The transmission mode adopts the lower roller full drive, does not hurt the material surface.
Width Forming Device: Front and rear each group, the width forming plate adopts chromium steel, the surface is treated by high frequency chromium plating, and the manual retaining material is used to determine the width plate to ensure the diagonal accuracy of the material.
Support Part : The surface of the roller is treated with chromium plating without damaging the surface of the material.
Material Arc Control: To ensure that there is a reasonable buffer arc between the feeder and the l eveling machine. Frequency converter through the sensor feedback signal to the coil intermittent rotation discharge.

Power Supply: AC380V±10%,50HZ ±2% Three-phase five-wire system

Control Description:

1. Connection with punching machine: by connecting two groups of cam signals to control the relaxation and feeding action, the angle position of cam induction can be adjusted to adjust the action time of relaxation and feeding.
2. Parameter setting: the parameters such as feeding length, feeding speed, feeding times (output) are modified by color high-definition LCD touch screen. Setting does not need to adjust any mechanical mechanism, easy to learn.
3. Manual / automatic control: manual control can be used when adjusting die, control handle also needs to be used when manual control. Automatic control is the automatic operation of the feeder according to the cam signal of the punching machine.
4. Alarm / fault handling: when the output reaches or some locked alarm, the alarm screen will automatically pop up and tell the cause of the fault. The operator can see the cause of the fault and reset it accordingly.
5. Counting function: feed times up to the set number of stop and alarm.
6. Control handle: for the external hand control device, set point in, point back, single, relaxed / clamped function, in the mold adjustment operator use handle in the mold side operation, fast and convenient.
7. Emergency stop: equipped with emergency stop protection button, machine equipment problems can be photographed button stop feeder.
