What is the function of the uncoiler? - WORLD MACHINERY

View Details

Decoiler is a term used in the printing industry to describe a device that helps unwind and level out coils of paper or other materials. Decoilers can be manual or automatic, and they are used in a variety of applications, such as commercial printing, packaging, and label printing. A decoiler can help improve the quality of your prints by ensuring that the material is unwound evenly and smoothly.

What is the structural composition of the decoiler?

The body of the uncoiler is a welded box-shaped structure, and the variable-frequency speed-regulating motor drives the real shaft to provide the main power for the uncoiler after being decelerated by the gear box. The reel of the uncoiler is a hollow shaft, which is supported on the gear box by two bearings, and a transmission spur gear is installed between the bearings. The gearbox is lubricated by forced lubrication and equipped with two constant speed motors for a closed-loop oil lubrication system. The mandrel is a cantilever structure, and its front end is supported by an external support bearing to maintain the rigidity and stability of the uncoiler when uncoiling.

What is the function of the uncoiler?

The uncoiler is a special equipment for metal plate leveling. It is used for leveling steel plates and uneven plates. It can be composed of uncoiling, leveling, shearing production lines and other plate product production lines according to relevant configurations. It is suitable for machinery, vehicles, metal products, household appliances, steel structures, decoration and other industries.

The uncoiler is one of the essential equipment in the welded pipe production line. One of its functions is to support the steel coil by tightening the inner hole of the steel coil; The other is to send the head of the steel strip to the leveling machine. Therefore, the performance of the uncoiler is very important to the entire production line. During years of design practice, the structure of the uncoiler has been continuously optimized and improved, so that the performance of the uncoiler has been improved.

What are the operating requirements of the uncoiler?

1.In the loading operation, a special person should cooperate with the forklift driver to make the steel coil material basically consistent with the center of the expanding and shrinking reel shaft, and then the forklift driver slowly put the steel coil material on the trolley.

2. The operator wants to raise or lower (lift trolley), adjust the steel coil material to the center of the expansion and contraction reel shaft (that is, the material can go into the expansion and contraction shaft), and at this time adjust the movable bearing seat at the top of the uncoiler to make it consistent with The uncoiler remains on the same level.

3. Adjust the expansion nut to make the four arc plates and the steel coil material expand tightly to avoid deformation and damage of the steel coil material during work.

4.When the steel coil material is swelled, turn the uncoiler by hand to observe whether the material can rotate freely, so as to avoid various hidden dangers in the work.

Working principle of decoilers

Decoiler is an auxiliary feeding equipment used in the automatic processing production line of coil stamping, leveling, laser cutting, and cutting line. Its function is to open the coil and lead out the material head so that it can enter the subsequent machine in the production line. The operation is very simple and fast.

The working principle of the uncoiler: expansion and contraction uncoiling method, the coil is vertically placed on the expansion and contraction drum, and when the expansion and contraction drum is tightened by the motor, it drives the expansion and contraction drum to rotate and open the coil. Then the material strip naturally hangs down after opening, and automatically stops when it contacts the induction bracket, and continues to feed after leaving the induction bracket.

The uncoiler is a supporting equipment for the leveling of metal plates. It can be used to form an uncoiling, leveling, and cutting production line and other sheet product production lines for leveling steel plates and uneven plates according to relevant configurations. The operation is very simple and fast.

Structure and unwinding of a decoiler machine

The uncoiler is a device designed specifically for unwinding metal coils and can be used for unwinding and rewinding of metal coils. It is widely used in the fields of home appliances, automobiles, hardware, electronics, etc., greatly improving production capacity and reducing labor costs.

The structure of the decoilers is simple. The heavy-duty standard material rack is composed of a frame, a material rack, tiles, a motor, a reducer, an electric box, and so on. The overall structure is compact and occupies a small area. The production efficiency can be further improved through reasonable wiring and equipment quantity.

Before the metal coil is stamped, it needs to be uncoiled by the decoilers and then fed to the punching machine by the feeder. So how does the uncoiler work? Firstly, the speed of the standard equipment is fixed at 15m/min. After the operator places the coiled material on the material rack, turn on the power, and the automatic and positive rotation knobs to start working. The material achieves the purpose of unwinding with the rotation of the material rack, and stops when the length of the unwound material reaches the stamping condition. The start and stop of the material rack are controlled by the induction bracket at the front end of the material rack.

In some companies, the load, material width, thickness, inner and outer diameter, uncoiling speed, and other parameters of the standard decoiler machine cannot meet their unwinding requirements, and can be customized according to customer needs. As an important link in the stamping process, the uncoiler is favored by major companies for its advantages of convenient operation, safety, reliability, and high cost performance. The market share is very large, and can be matched with leveling machine and feeder to form a complete set of automatic production line with the punching machine.
