The important product - Dali circular knife 91212, can be used to process various textiles such as sheep wool, UV cloth, carbon fiber, banners, flag cloth, blackout cloth, etc.

The basic principle of circular knife is to use the motor to drive the blade to rotate at high speed to cut the material. Different materials can be processed by matching different blades.

The circular knife can choose different types of cutter heads according to needs.

Instructions for use and debugging

(1) Cutting head installation

Check if there is a gasket on the tool head coupling (the gasket may also be at the connection in the middle of the tool handle).

Align the M5 threaded fastening hole of the tool head with the M5-90 countersunk screw hole and insert it (pay attention to the groove at the connection when inserting, and connect it accordingly).

Finally, put in the M5-90 countersunk screw and tighten the screw with a hexagonal wrench to fix the tool head.

(2) Blade installation

Clamp the blade between the blade fixing ring and the blade tightening wire. Pay attention to the clamping surface of the blade fixing ring and the blade tightening wire when clamping.

E2 and long zero round cutter head

Direct-insert and B3 round cutter heads

Use an open-end wrench to tighten the blade screw, and then use an Allen wrench to tighten the blade counterclockwise. Finally, tighten the blade cover (which can also be removed and replaced with a presser foot assembly), and the blade installation is complete.

(3) Presser foot installation

Align the M3 cylindrical countersunk hole of the presser foot with the M3 threaded fastening hole of the cutter head, and then tighten the screw with a hexagonal wrench.

(4) Frequency adjustment

The frequency can be adjusted by rotating the adjustment hole on the driver. Insert a small cross screwdriver into the adjustment hole and turn it clockwise to increase the vibration frequency, and counterclockwise to decrease the vibration frequency. (Note: The adjustment knob is a precision electronic component and cannot be adjusted too large).

Wiring Instructions

The wiring of the 91212 round knife requires a switching power supply of 24V15A or above. It is recommended to use an independent power supply

Wiring 1 (the power cord of the knife handle is blue/yellow/black)

Wiring 2 (the power cord of the knife handle is red/yellow/black)

1V+	DC24V+
2GND	24V-orCOM
1MA—2MB—3MC	Connecting handle
1GND—3EN	Control signal line
5SV—8+5V	Short Circuit

Swap the three-phase wires of the motor to change the rotation direction of the blade

The blade rotation and cutting direction are shown as the arrows. To change the blade rotation direction, just swap any two of the three-phase wires (the three-phase wires at the driver or the handle can be swapped, and only one of the two places needs to be changed).

Precautions

Configure a separate switching power supply, it is recommended to configure 24V15A or above
Before powering on, confirm that the wiring is correct
Do not use too much force when tightening the blade
Non-professionals are not allowed to disassemble the blade head
Pay attention to safety when installing the blade
Pay attention to the direction of blade rotation! If it rotates in the opposite direction, the blade is easy to loosen
It is required to connect clean and dry compressed gas. (For example, use a pneumatic triplex to filter, reduce pressure and refuel the gas to ensure the normal operation of the pneumatic actuator and prevent malfunctions due to impurities, excessive air pressure or lack of oil.)
