Maximum Tension 1000N Atutomatic Constant Tension Controller KDT-A-1000 High Precisely
Introduction
The tension control of the tension controller refers to the ability to permanently control the tension of the tape as it is transported on the device. The automatic tension controller KDT-A-1000 is an automatic control system that realizes constant tension control. Its function is mainly to achieve synchronization between the rollers and continuously uniform control of rewinding and unwinding. Automatic tension control system consists primarily of an automatic tension controller, pressure sensor, magnetic powder brake or clutch. It is suitable for high-precision and high-speed tension control applications, and has the advantages of high control precision and good real-time performance.

Parameters

Automatic tension controller

​Manual tension controller

Features

1. Usually working with load cell.

2. Automatic tension adjustment according to the loadcell.
3. Fast and precise control the tension.
4. The rotation speed then pre-set tension maintain by the roller when printing material rotate through the printing machine, no matter what the size, width, material.
5. Tension sensors roller monitor the roller tension of the material and amend any changes of the tension.

6. Maximum tension can up to 1000N.

7. Mutli connection MODBUS RS485.

Control mode

1. Manual panel control.

According to the winding unwinding situation, the manual knob adjustment is manually performed to control the magnitude of the exciting current to obtain the required tension.

2. External PLC control.

The PLC needs to be equipped with a 10V analog output module. With the tension detector, automatic constant tension control can be formed, or manual adjustment can be made through the touch screen.

3. External potentiometer control

The short wiring of +10V and ADJ needs to be removed, and the panel knob must be twisted to the right.

Note: The magnetic powder brake and clutch wiring is not divided into positive and negative poles.

Application

1. Printing systems: conveyors and in-feeders
2. Wood-working systems: saws, wood-working machine, laminators
3. Testing systems: lab machines, durability testers, measuring systems
4. Food processing systems: meat cutting machines, cookie making machines, canning machines, noodle making machines

Feeding process:
Torque motor output torque, connected to magnetic powder brake, then the brake connects with the feeding shaft to feed the material. Electric torque-motor controller control the torque motor, tension controller control the magnetic powder brake, resulting in uniform material feed and proper speed.
Rewinding process:
Torque motor output torque, connected to magnetic powder clutch, then the brake connects with the rewinding shaft to collect the material. Electric torque-motor controller control the torque motor, tension controller control the magnetic powder clutch, resulting in uniform material rewind, proper speed and roll tight.

Advantages

1. Automatic unwind tension system deploys material tension detection roller.
2. The device will support auto-stop operation when material tension reaches the upper and lower limitation.
3. Unwinder device deploys automatic compensation tension control device.
4. The rotation speed then pre-set tension maintain by the roller when printing material rotate through the printing machine, no matter what the size, width, material.
5. Tension sensors roller monitor the roller tension of the material and amend any changes of the tension.

FAQ
1. When can I get the quotation?
We usually quoted within 24 hours after receiving your inquiry. If you are very urgent to get the price, please call us or tell us in your email, so that we can regard your inquiry priority.

2. How should I place the order?
Please let us know the model number based on our specs for powder clutch, powder brake, air clutch, air brake, electromagnetic clutch, electromagnetic brake and safety chucks. For air shaft and roller, please show us your drawing, or let us know your request, and then we will provide you drawing for confirmation.

3. What’s your MOQ basis?
Normally, we don’t have MOQ request, except the rollers.

4. What about the lead time for production?
