In the previous article, we have introduced what the decoiler is and the classification of the decoiler. Through this article, we can quickly get to know the decoiler, but what kind of decoiler is the best for you? Next, we will teach you how to choose a decoiler that suits your workshop production needs.
There are generally three steps to determine a decoiler that suits you.
1.Identify the basic parameters of the material, width, thickness, weight, inner diameter, and outer diameter of the material.
You can roughly know the type of decoiler you need by first clarifying the basic properties of the material.
2.Understand your own processing and production situation to choose the configuration of the decoiler.
a. Frequency control configuration
This function enables the decoiler to freely adjust the speed according to the demand, increase the stability of the decoiler, make the material strip discharge more smoothly, and reduce jitter.(For example, when the customer uses the decoiler with the leveling machine, because of the frequency converter speed regulation, it will be relatively stable at startup, and the material will not be stretched and bent due to sudden startup.And it is relatively stable when stopped, and the material will not be loosened due to the inertia of the coil. )
b. Cylinder pressing arm device
The cylinder pressing arm is to press the outer ring of the material to avoid the problem of bulk material when the coil is uncoiled. Usually when the thickness of the material exceeds 2mm, it can be recommended to customers.
c. Adjustment of inner and outer diameters
The inner diameter of the international coil is 508mm and the outer diameter is 1200mm.
The inner diameter range is 450-530mm, and the maximum outer diameter is 1200mm. If it is not in this range, it needs to be customized.
d. Hydraulic expansion device
This device is installed on the decoiler to replace the standard manual expansion device, which ensures that the decoiler can be fully stretched and at the same time reduces the labor intensity of manual expansion. Usually, when the weight of the coil is 3 tons, it can be recommended to customers. (Of course, some customers also use it when it is less than 3 tons in order to save labor.)
e. Hydraulic loading trolley
It is recommended for customers to use when the weight of the coil exceeds 3 tons or the material is very wide.
f. Photoelectric induction device or proximity switch induction device
Used to replace standard touch sensor rods for unwinding non-conductive or film-coated materials. (If the customer is this material, this configuration needs to be adopted)
3. Clarify the size of your own production workshop, as well as the model and processing technology to be matched with the uncoiler in the future.
Because it is necessary to consider whether it needs to be matched with other models and processing technologies in the future, this will have further requirements on the uncoiler.Whether there are requirements on the surface of the material, if the surface of copper and aluminum needs to be coated, an additional coating device needs to be added at this time. If it is determined that the material needs to be covered, it is necessary to use variable frequency speed regulation to prevent the material from being pulled.
Because there are various production situations and needs, it is difficult for customers to consider them comprehensively. Therefore, the selection of the decoiler is very important, and it must be selected according to the needs, so as to truly ensure that it meets the needs of the post-processing technology.
So before deciding to buy an decoiler, understand your basic needs, and then consult Henli, we will give you the best buying advice.
As shown in the picture, this is a case we made for a Finnish customer. According to the production situation of the customer’s site, we designed a decoiler project, which perfectly meets the needs of the customer.
So don’t underestimate the decoiler, choose a correct decoiler to really improve the production efficiency.
