[0019] The present invention provides a flat mask fabric unwinding device and method, which has the following beneficial effects:

[0020] (1) In the present invention, the movement of the slide rod away from the motor will drive the trapezoidal block to move away from the motor. The movement of the trapezoidal block away from the motor will lose the squeeze on the trapezoidal slider. The trapezoidal slider will reset under the elastic force of the No. 1 spring.

At the same time, the rotation of the rotating rod will drive the universal ball to rotate. The rotation of the universal ball will contact the unwinding disk, and the universal ball will provide support for the unwinding disk, thereby improving the stability during rotation.

[0021] (2) In the present invention, the downward movement of the connecting seat will drive the free end of the elastic telescopic plate to move downward, and the downward movement of the free end of the elastic telescopic plate will drive the rotating roller to move downward. The downward movement of the rotating roller will squeeze the fabric on the unwinding disk to prevent the fabric roll from loosening on the unwinding disk during unwinding, causing the fabric roll to collapse and affecting the unwinding efficiency. At the same time, the downward rotation of the rotating frame will drive the rotating roller to rotate downward. The rotating roller and the rotating roller will squeeze the fabric to prevent the fabric from wrinkling during unwinding, which will affect the sale of the fabric.

[0022] (3) In the present invention, the movement of the connecting frame in the direction away from the inner wall of the chassis will push the push plate to rotate, and the rotation of the push plate will drive the rotation of the rotating plate, and the rotation of the rotating plate will drive the guide wheel to rotate.

[0035] A method for using a flat mask fabric unwinding device comprises the following steps:

[0036] Step 1: When the unwinding reel 5 needs to be replaced, the revolving door 2 is opened, and the revolving door 2 is opened to break away from the contact with the rotating block 8. The rotating block 8 loses the squeeze and resets under the elastic force of the elastic telescopic rod 6 itself. The elastic telescopic rod 6 resets and drives the sliding rod 7 to move away from the motor 3;

[0037] Step 2: The slide bar 7 moves in a direction away from the motor 3, driving the trapezoidal block 9 to move in a direction away from the motor 3. The trapezoidal block 9 moves in a direction away from the motor 3 and loses the squeeze on the trapezoidal slider 10. The trapezoidal slider 10 is reset under the elastic force of the first spring. The trapezoidal slider 10 resets and loses the limit on the unwinding disk 5, so that the staff can quickly disassemble the unwinding disk 5, thereby improving the replacement efficiency.

[0038] Step 3: When the revolving door 2 is replaced, the revolving door 2 squeezes the rotating block 8 and the slide bar 7 to move in the direction close to the motor 3. The slide bar 7 moves in the direction close to the motor 3 to drive the trapezoidal block 9 to move in the direction close to the motor 3. The trapezoidal block 9 moves in the direction close to the motor 3 to push the trapezoidal slider 10 to move upward. The trapezoidal slider 10 moves upward to limit the unwinding disk 5 to prevent the unwinding disk 5 from shaking back and forth during the rotation process, resulting in deviation during unwinding;

[0039] Step 4: The revolving door 2 rotates to drive the rotating rod 11 to rotate, and the rotating rod 11 rotates to drive the universal ball 12 to rotate. The universal ball 12 rotates and contacts the unwinding disk 5, and the universal ball 12 provides support for the unwinding disk 5 to improve the stability during rotation.

[0040] When the present embodiment is working, when it is necessary to replace the unwinding disc 5, by opening the revolving door 2, the revolving door 2 will be out of contact with the rotating block 8 when it opens. The rotating block 8 loses the extrusion and will reset under the elastic force of the elastic telescopic rod 6 itself. The resetting of the elastic telescopic rod 6 will drive the sliding rod 7 to move in the direction away from the motor 3. The movement of the sliding rod 7 in the direction away from the motor 3 will drive the trapezoidal block 9 to move in the direction away from the motor 3. The movement of the trapezoidal block 9 in the direction away from the motor 3 will lose the extrusion on the trapezoidal sliding block 10. The trapezoidal sliding block 10 will reset under the elastic force of the No. 1 spring. The resetting of the trapezoidal sliding block 10 will lose the limit on the unwinding disc 5, so that the staff can quickly disassemble the unwinding disc 5, thereby improving the replacement efficiency, and at the same time When the revolving door 2 is replaced, the revolving door 2 will squeeze the rotating block 8 and the sliding rod 7 to move in the direction close to the motor 3. The movement of the sliding rod 7 in the direction close to the motor 3 will drive the trapezoidal block 9 to move in the direction close to the motor 3. The movement of the trapezoidal block 9 in the direction close to the motor 3 will push the trapezoidal sliding block 10 to move upward. The upward movement of the trapezoidal sliding block 10 will limit the unwinding disk 5 to prevent the unwinding disk 5 from rocking back and forth during the rotation process, resulting in deviation during unwinding. At the same time, the rotation of the revolving door 2 will drive the rotating rod 11 to rotate, and the rotation of the rotating rod 11 will drive the universal ball 12 to rotate. The rotation of the universal ball 12 will contact with the unwinding disk 5, providing support for the unwinding disk 5 through the universal ball 12, thereby improving the stability during rotation.

7. A method for using a flat mask fabric unwinding device, using the flat mask fabric unwinding device according to claim 6, characterized in that: The following steps are involved: Step 1: When the unwinding reel needs to be replaced, the revolving door is opened, and the revolving door is opened to break away from the contact with the rotating block. The rotating block loses the squeeze and resets under the elastic force of the elastic telescopic rod itself. The elastic telescopic rod resets and drives the sliding rod to move away from the motor; Step 2: The slide bar moves away from the motor, driving the trapezoidal block to move away from the motor. The trapezoidal block moves away from the motor and loses the squeeze on the trapezoidal slider. The trapezoidal slider is reset under the elastic force of the No. 1 spring. The trapezoidal slider resets and loses the limit on the unwinding disk, so that the staff can quickly disassemble the unwinding disk to improve the replacement efficiency. Step 3: When the revolving door is replaced, the revolving door squeezes the rotating block and the slide bar to move toward the motor. The slide bar moves toward the motor to drive the trapezoidal block to move toward the motor. The trapezoidal block moves toward the motor to push the trapezoidal slider to move upward. The trapezoidal slider moves upward to limit the unwinding disk to prevent the unwinding disk from shaking back and forth during rotation, resulting in deviation during unwinding. Step 4: The rotation of the revolving door drives the rotating rod to rotate, and the rotation of the rotating rod drives the universal ball to rotate. The universal ball rotates and contacts the unwinding disk, providing support for the unwinding disk through the universal ball to improve the stability during rotation.
