Spiral looper

• Simple and reasonable;
• The steel belt loop does not go off track；
• No loose circles；
• Large storage capacity;
• High productivity;
• Feeding is variable frequency speed regulation.

The size is determined according to the customer’s location, the width and thickness of the strip. The hopper is used to store and discharge materials to ensure the continuous operation of the main machine in order to meet the continuous operation of the welding pipe and photovoltaic production line. The number of storage circles in the loop is fixed. When the coil change, uncoiling, shearing, and butt welding stop feeding into the loop, the material close to the outer cage in the loop is pressed against the inner cage one circle at a time to ensure continuous discharge. When the steel strip is butt-welded, the loop is filled with material at a speed 2-3 times that of the welding pipe, so that the steel strip close to the inner cage is pressed against the outer cage one circle at a time under the action of runoff with a natural expansion trend until all of them are pressed against the outer cage and the material is full. At this time, the filling speed is equal to the welding pipe speed. This is the synchronization stage. The loop can ensure continuous feeding of the unit according to this cycle.

The biggest function of the spiral looper is that the spiral looper can store more materials and prevent scratches and creases on the strip steel, thereby increasing production capacity and the rate of finished products. It is fully prepared for the sizing of steel pipes, ensuring continuous operation without stopping, greatly increasing production. It is an auxiliary equipment for welding pipe lines, photovoltaic lines, and seismic support production lines, and can be customized according to the customer’s site size.
