mechanical properties

1、 Main components and functions of the equipment：

1.Material unwinding section:

a. The unwinding adopts a top cone unwinding method, using the top cone principle to automatically locate, position, and press the pole coil. The center of the polar roll unwinding is symmetrical. The concentricity and roundness are high during the unwinding motion of the polar coil. Avoiding the defects of loose and tight pole pieces and unstable tension during the unwinding process of the inflation shaft.

b. Adopting an automatic closed-loop tension control system, with a graphical LCD display, digital adjustable, and constant tension unwinding, the unwinding tension is automatically adjusted according to the size of the winding diameter. The pole tension is stable and the tension control accuracy is extremely high;

2.Correction system:

The high-performance correction guide is composed of ultrasonic testing (not affected by the appearance or shape of the pole piece), automatic correction guidance system, fiber optic sensor, high-speed microcomputer signal controller, and precision ball screw DC servo actuator to ensure the neat operation of the pole piece.

3.Connecting part:

Configure an independent feeding platform, with two sets of cylinders pressing the beginning and end of the material respectively, and manually complete the feeding with tape.

4.Unwinding traction part：

Drive the traction roller with a servo motor, synchronize with the tool line speed, and press the rubber roller on the active roller through the cylinders at both ends to achieve material compression, fully realizing separate control of unwinding and rewinding tension.

5.Adjust the floating roller：

Before the material enters the cutting die, a floating roller is configured to mainly improve and balance the defect of loose and tight sides of the material after rolling, so as to evenly distribute the tension of the materials on both sides and improve the cutting effect.

6.Cutting knife holder section：(Won the National Brick Award:ZL.0）

a. Adopting a movable adjustable precision knife holder, the knife holder is made of imported materials and refined through special processes, never changing

Shape and high cutting accuracy. The knife holder can be adjusted up and down, allowing the blade to be repeatedly ground more than 20 times

Greatly extended the service life of cutting tools and saved 600% of consumables.

b. Equipped with disc type precision cutting tools and suspended slitting method. The knife holder is equipped with a hydraulic trolley for motion transfer, which is convenient

Use when changing models of different specifications and blades on the device.

7.Roll up tension control system：

The precise tension sensor detects the applied force on the tension roller in real time, and the professional closed-loop tension controller directly controls the electrical proportional valve. Through the electrical proportional valve, the air pressure of the winding slip shaft is controlled to change the friction force of each unit on the slip shaft, thereby controlling the tension. The control system is completely closed-loop controlled, with high control accuracy and sensitive response. During operation, the set tension of the system is close to the actual tension. To avoid fluctuations in tension during startup and shutdown, there are also shutdown tension and reserve output tension to ensure continuous tension during startup and shutdown. The tension control system is designed with advanced technology, high control accuracy, and a wide range of tension settings.

8.Discharge adjustment roller：

Equipped with discharge digital adjustment rollers for visual fine-tuning, improving the quality of pole piece cutting.

9.Edge material traction device：

By using synchronous rubber rollers to pull the edge material, a certain amount of tension is generated to improve the cutting effect of the two edges of the material.

10.Efficient powder brushing, dust removal, and deburringSystem (Rong)Obtained national invention brick profit and practical brick profitZL.0）

a. Surface of polarizer: Use two sets of roller brushes (four in total) to clean the sliced polarizer with powder, and prepare

There is a dust hood and pipeline interface to facilitate customer dust collection.

b. Side of the polarizer: automatic powder/burr brushing function on the edge of the polarizer, the brush can be rotated and adjusted along the roll diameter direction

The width direction position of the pole roll can be adjusted arbitrarily, making it easy to adapt to the pole roll position and automatically suction

Remove dust and metal shavings from brushing;

c、 Tool surface: During cutting, the dust attached to the tool body is completely embedded and wiped and absorbed by carbon fiber,

Automatic dust collection.

11.Roll up section：

The upper and lower winding slip air expansion shafts are used for synchronous winding. The winding slip air expansion shaft adopts advanced internal expansion tensioning, making unloading convenient and fast. The winding speed is controlled by frequency conversion, ensuring that the winding and slitting line speed slip is always maintained during the equipment's start-up, acceleration, operation, deceleration, and shutdown processes Ensure stable system speed and tension.

12.Pneumatic compression device (pressure bar) for winding materials：

When the equipment stops running, it can compress the slitting material. This mechanism is very convenient to use during shutdown, short strip, and threading processes, and is compressed by a cylinder.

13.Detecting roll diameter：

Real time and * * detection of roll diameter size using German ultrasonic sensors. And display it on the touch screen.

14.Number of polarizer detection：

Fiber optic sensors detect the number of segmented pole pieces, which can be used to count the number of segmented pole pieces for the day, as well as for the week and month

Accumulated number of segmented poles, with multiple specifications to choose from.

15.Tool usage management function：

The system has a cumulative usage of 24 cutting specifications, which can effectively provide users with a basis for instant blade replacement. The operator only needs to select the cutting specification on the touch screen each time, and the system automatically accumulates the total number of meters already cut by the cutting die.

16.Material receiving roller：

After slitting, each pole piece is equipped with a pressing roller to improve the neatness of winding. Automated control through pneumatic and program linkage.

17.Main functions of human-machine interface：

Equipment debugging (manual mode): line speed debugging, manual function debugging.

Set the tangent line speed and servo motor acceleration/deceleration time.

Display the current cutting line speed, cutting meters, winding diameter, number of polarizer pieces, etc. of the device.

Polar chip specification management screen: Accumulated number of segmented polar chips per shift for different specifications.

Tool management screen: Accumulated cutting meters of different specifications of tool molds and tools used.

Fault display and fault alarm records, etc.

18. The key components of the machine are made of imported materials and undergo special processes such as high-temperature forging and vacuum heat treatment. They are processed by a machining center

One time processing molding, never deformed, with extremely high precision; During the assembly process, all rollers are subjected to parallelism and dynamic balancing

Strictly inspect and debug to ensure the stability and reliability of the machine during long-term use. （Winning the National Brick Award：
