#coil #processing
The scrap baller is an excellent choice for us to dispose of waste materials. It rolls the cut edges into a ball and recycles them, and sorts the cut edges in a simple way. The scrap baller provided by BOYA adopts a unique modular design, and its processing performance and control accuracy have reached a high level.

Structure Advantage of Scrap Baller
Bridle scrap baller adopts mandrel and swing frame, guide the scrap from chute of the side trimmer winding into coil. Pit not required.

Tension scrap baller is applicable for thicker material, high strength, convenience to winding.
Non-tension scrap baller adopts mandrel and follow up frame to pull scrap edge out of pit and winding, no need to stop the unit for guiding the scrap edge, saving production time and meeting the requirements of continuous production.

Tension scrap baller is applicable for thicker and lower strength material.

Main Components for Scrap Baller
Scrap baller consists of 5 parts: Drive part, Snuber roll, Frame Part, Fixed base, transversal shifting device.

Drive part: Drive part is composed of shift base, frequency conversion motor, scroll, frequency conversion motor drives reel rotation to rewind the scrap edge to mandrel, frequency conversion motor installed on the shift base, when need to discharge scrap ball, oil cylinder push the shift base back, take the mandrel out of scrap ball, under the action of gravity and pressure roll, scrap ball will rolling out of the scrap baller and falling into scrap pit.

Snubber roll Part: Snubber roll part consists of oil cylinder and snubber roll, when working snubber roll give pressure to scrap ball by oil cylinder, after finished winding, snubber roll will push the scrap ball out so as to ready for next winding.
Frame Part: Frame part consists of frame, mandrel support base, stop disk, cylinder, etc, mandrel insert into support base by shifting cylinder when winding, to support the cantilever end of mandrel, avoid mandrel swing during winding scrap edge and increase the using life of equipment.

Fixed Base: The fixed base is the foundation of the scrap baller. The box is welded structure with stiffened plate in the middle to improve its rigidity. The post-welding aging treatment will improve its stability.

The shift cylinder is mounted on the base, and the shift base moves left and right under the action of the cylinder to complete the preparation of coiling and uncoiling. The flat cable oil cylinder is fixed on the inlet side of the coiler, and the side guide roller pushes the side scrap edge to move left and right reciprocately, ensure that the scrap edge is wound evenly on the reel.

Structure Advantage of Rotary Sheet Metal Shear for Annealing and Galvanizing Line

The single-side shearing knife box of the disc shears is for one use and one preparation, and can be quickly switched through the rotary mode, so that the unit can quickly change the tool without stopping the machine.

The disc cutter is equipped with a tool change and maintenance platform, which can realize online tool change and maintenance of the spare tool box.

The disc knife adopts the end face grinding method, the hydraulic nut is locked, the upper knife adopts the front rigid positioning, and the lower knife adopts the rear rigid positioning, which can greatly improve the convenience of equipment operation and maintenance and reduce the ineffective consumption of spare parts.

Equipped with cutter cleaning device and scraper mechanism, it can guarantee and prolong the service life of the disc blade.

Electromechanical and hydraulic control integrated products, equipped with reliable Siemens control system and optimized process adjustment template, can effectively ensure stable product quality.

Rewinding Line

https://www.boyamachinery.com/....products/rewinding-l
#tension #leveler
Rewinding/ recoiling lines will encounter the problem of strip skidding during the actual usage which can lead to production barriers like strip deviation, at the meantime, coil processing lines can affect the security of production equipment. With the pressure roller, tension rolls for the rewinding unit can prevent the strip from slipping on the surface of the rolls and get initial tension.

BOYA Rewinding Line Features

The force increase of tension roller unit was achieved by wrapping effect of each tension roll.

In the condition of the rewinding line wrapped around a roll was affected by a certain initial tension, the friction force between them reached a maximum number and the transfer power outreached the maximum friction, there will be skidding between the strip of recoiling line and the roll surface.

Automatic Sleeve Feeding arrangement system.

Entry Flattener with Quick Opening Feature.

Doctor blade to be provided for all entry/exit deflector rolls, bridle rolls, and turn rolls.

The Coil car will have auto coil shuffling to move the coils up to saddle one.

Full line canopy covers.

The Belt Wrapper is designed in such a way that it will be suitable for under and recoiled.

Tinplate and Carbon Steel.

Trimming Speed: 720Mpm Leveling Speed: 600Mpm

Rewinding Line Strengths

The coil car will be lifted up to the collapsed mandrel So that we can easily unload small coils from the mandrel.

Low pressure system to prevent damage when removing small coils.

Improve the flatter efficiency.

High precision and stable control system.

Safety and reliable production process.

Compact structure and easy maintenance, environmental protection.

Rewinding Line Working Principle
01
The recoiling line running speed also can affect the total friction between the strip and the roll surface. When the strip runs under a higher speed, the positive pressure of the strip on the roll surface is lower, and the gas passing between strip and roll surface in the entrance cannot be exited quickly, which can continue to accumulate with the increase of speed. Therefore, on the one hand, the actual wrap angle between the strip and the roll surface is reduced, on the other hand, the coefficient of friction between them is also diminished. Finally, all of them results in the decrease of the whole friction, which can be represent apparently under the poor incoming plate shape. In conditions of the same initial tension of tension roller unit, the entrance roller unit with a small force has a higher slip probability than the exit one with a higher force.

02
The slipping of any tension roll unit will cause scratches to the surface of the strip. In the rewinding line, the light damage can degrade product quality, while the heavy one will scrap the strip. So the slipping of the tension roll unit is extremely harmful to production.

03
At the same time, the slipping of any tension roll unit will have a direct effect on itself, which can make the roller surface smoother and smoother. The friction coefficient diminished rapidly, so we need to regrind the roll surface and the roll usage period will be shorted. In addition, the skidding of tension roller unit can cause motor output torque to fluctuate, impact the transfer decelerator, make gear failure and defect the decelerator.

04
In order to prevent slipping, rewinding line diameter is selected based on the principle that no plastic deformation occurs after the strip passed through the tension roller. The max thickness of coil processing line strip is the main factor to determine the max diameter of tension roller. The phenomenon that the slipping probability of cold-rolled thin strip steel is significantly increased under the large tension roll diameter. There should be a limit to the adaptation scope of strip, the diameter of tension roller is not the bigger the better. In order to add the friction coefficient as soon as possible, we need to increase the roughness of the roll surface.

05
Although we cannot eliminate the slipping of tension roll through the way of improve the electrical control of tension roller unit, we can provide the reasonable and perfect electrical control method which can benefit to diminish the degree of slippage. Therefore, we can decrease the wear of tension roll, and it is helpful for us to find and correct the slipping.
