uncoiler

Strong Power Output:

Adopts high-power variable-frequency motors (with optional power ranging from 5kW to 50kW) and high-precision gearboxes, with a maximum torque of up to 3000N・m and an adjustable uncoiling speed of 0-30m/min. Even when dealing with high-strength alloy coils and heavy-weight coils (with a single coil weight ≤ 80 tons), it can achieve stable and continuous uncoiling, and the single-shift processing capacity is increased by more than 50% compared with traditional equipment.

Whole-Line Linkage and Coordination:

It can seamlessly link with equipment such as levelers, shears, punch presses, and recoilers. Through the PLC control system, it realizes speed synchronization (with a synchronization error ≤ 0.5m/min), forming a full-process automated production line of "uncoiling - processing - conveying - recoiling". This eliminates the waiting time between processes, increases the overall efficiency of the production line by 40%, and meets the needs of large-batch and high-rhythm production.

IV. Comprehensive Safety Protection: Building a Solid Safety Barrier for Production

Upgraded Physical Protection:

Equipped with fully enclosed protective fences (height ≥ 2m, protective net aperture ≤ 30mm×30mm), anti-coil falling blocks (load-bearing ≥ 15 tons), emergency stop buttons (response time ≤ 0.2 seconds), and protective covers for key rotating parts. These prevent safety accidents caused by personnel accidental contact or coil loosening, and comply with international safety standards (such as CE and ISO).

Intelligent Safety Early Warning:

It monitors the equipment operation parameters in real time (motor temperature, reel load, tension value, oil pressure). When the parameters exceed the safe range (e.g., motor temperature ≥ 90℃, load exceeding 130% of the rated value), it automatically shuts down and issues an audible and visual alarm. At the same time, fault codes and handling suggestions are displayed on the operation screen, facilitating quick troubleshooting and reducing equipment damage and safety risks.

V. Low-Cost Operation: Reducing Long-Term Production Investment

Reduction of Material Loss:

Through precise tension control and centering technology, the material waste of coils caused by deformation and deviation is reduced. Calculated based on processing 200 tons of coils per day and a 0.5% reduction in waste rate, the annual material loss can be reduced by approximately 360 tons, directly saving hundreds of thousands of yuan in raw material costs.

Energy-Saving and Consumption-Reducing Design:

Adopts variable-frequency speed regulation technology, which reduces energy consumption by 40% when the equipment is running at no load; the hydraulic system is equipped with an energy-saving valve group, which reduces the loss and heating of hydraulic oil, and saves 20%-30% of electricity costs and hydraulic oil purchase costs annually.

Low Maintenance Cost:

Key components (reels, bearings, gears) are made of high-strength wear-resistant materials, and their surfaces are treated with special processes (such as chrome plating and nitriding), extending their service life by 60%; the equipment is equipped with a maintenance reminder function (such as lubrication cycle and component replacement early warning), which reduces the maintenance frequency and lowers the annual maintenance cost by more than 25%.

Product Details

I. Basic Product Information

1. Product Name

Uncoiler, also known as coil unrolling equipment, is a core front-end device in the coil processing production line. It is mainly used to unroll coiled metal or non-metallic materials, providing flat and continuous base materials for subsequent processing procedures.

2. Product Types

According to the driving method, load-bearing capacity and structural characteristics, it is mainly divided into the following types:

By driving method: Hydraulic uncoiler (driven by a hydraulic system, with strong power, suitable for heavy-weight coils) and mechanical uncoiler (relying on mechanical transmission, easy to operate, suitable for small and medium-batch production);

By load-bearing capacity: Light-duty uncoiler (single coil load ≤ 5 tons, suitable for thin and narrow-width coils), medium-duty uncoiler (single coil load 5-20 tons, meeting the needs of conventional metal coil processing), and heavy-duty uncoiler (single coil load ＞ 20 tons, up to 80 tons at maximum, used for high-strength and large-diameter alloy steel coils);

By structural form: Horizontal uncoiler (mainstream structure, small floor area, easy to link with subsequent equipment), vertical uncoiler (suitable for special coil placement needs, such as wide-width non-metallic coils), and double-head uncoiler (capable of alternate feeding, reducing downtime and improving production efficiency).

II. Core Configuration and Functions

1. Power Transmission System

Adopts a high-power variable-frequency motor (optional power range: 5-50kW), matched with a high-precision gearbox to achieve stepless speed regulation. The uncoiling speed ranges from 0 to 30m/min, which can be flexibly adjusted according to the subsequent processing rhythm;

The maximum output torque can reach 3000N・m, ensuring stable driving even when dealing with high-strength alloy coils and heavy-weight coils, and avoiding uncoiling jams.

2. Tension and Centering Control System

Intelligent tension control system: Adopts double closed-loop control technology to collect coil tension signals in real time and automatically adjust the braking force. The tension control error is ≤ ±2%, which prevents coil stretching deformation and wrinkling, and ensures the flatness of the uncoiled coil (the flatness error of metal coils is ≤ 0.1mm/m);

Precision centering device: Equipped with a laser + photoelectric dual centering system, the centering accuracy is ±0.05mm, and the horizontal adjustment range is ±50mm. It can automatically correct coil deviation, ensure that the coil center line is aligned with the feeding center line of subsequent equipment, and reduce the cutting waste rate to below 0.3%.

3. Safety Protection System

Physical protection: Fully enclosed protective fence (height ≥ 2m, protective net aperture ≤ 30mm×30mm) to prevent personnel from accidentally touching rotating parts; anti-coil falling block (load-bearing ≥ 15 tons) to avoid coil loosening and falling; emergency stop button (response time ≤ 0.2 seconds) to quickly cut off the equipment power supply;

Intelligent early warning: Monitors equipment operation parameters (motor temperature, reel load, tension value, oil pressure, etc.) in real time. When the parameters exceed the safe range (e.g., motor temperature ≥ 90℃, load exceeding 130% of the rated value), it automatically shuts down and issues an audible and visual alarm. At the same time, fault codes and handling suggestions are displayed on the operation screen to facilitate quick troubleshooting.

4. Auxiliary Functions

Automatic feeding and positioning: Some models are equipped with a hydraulic lifting platform and a coil clamping mechanism to realize automatic coil feeding and centering positioning, reducing the labor intensity of manual operation;

Parameter storage and recall: Equipped with a touch screen operation interface, which can store more than 100 sets of processing parameters. When switching between coils of different specifications, the preset parameters can be directly recalled without repeated debugging;

Whole-line linkage interface: Reserves a PLC control system interface, which can seamlessly link with equipment such as levelers, shears, punch presses, and recoiling machines to realize the full-process automation of "uncoiling - processing - conveying - recoiling".
