[0026] Specifically, as Figure 2As shown, the first motor 308 and the second motor 405 are AC asynchronous motors, which mainly consist of stator, rotor, bearing, shell, cooling system and terminal, and the working principle is based on electromagnetic induction phenomenon. When AC current passes through the stator winding, a rotating magnetic field is generated between the stator and the rotor, and then an induced current is generated in the rotor. This induced current interacts with the rotating magnetic field to generate electromagnetic force, which drives the rotor to rotate, thereby realizing the conversion of mechanical energy.

[0027] Specifically, as shown in the figure, Figure 1 The control panel is electrically connected with the powered equipment in the device. The control panel sends control instructions to each component through control signal lines. These signal lines can be analog signal lines such as 4-20mA current signals, digital signal lines such as RS485 communication interfaces, or simple switch signal lines. The control signals sent by the control panel are transmitted to the control units of each component through the signal lines. Through the buttons or touch screen interface on the control panel, the start and stop operations of each component can be realized. After receiving the start instruction, the controller will send corresponding control signals to start each component. When receiving the stop instruction, it will send a stop signal to stop each component. The working parameters of each component are set on the control panel interface. These parameter settings will be converted into corresponding control signals and sent to the control units of each component, thereby realizing accurate adjustment of the working state of the components. The control panel has the function of monitoring the running state of each component and can display the working parameters and state information of each component in real time.

[0028] Specifically, as shown in the figure, Figure 2 The first telescopic rod 401 and the second telescopic rod 406 mainly consist of motor, reducer, telescopic rod body, control system, guide component and limit switch. When the motor is powered on, a driving torque is generated. The high-speed rotation is converted into low-speed high-torque rotary motion through the reducer. The output shaft of the reducer is connected with the inner tube or outer tube of the telescopic rod. When the output shaft of the reducer rotates, the rotary motion is converted into linear motion of the telescopic rod through a screw pair or other transmission mechanism. The control system adjusts the speed and direction of the motor according to the preset parameters, thereby controlling the speed and direction of the telescopic rod. When the telescopic rod reaches the preset position, the limit switch sends a signal to stop the motor through the control system, thereby realizing accurate positioning of the telescopic rod.

[0029] In implementation, the following steps are performed:

[0030] 1) Rotate the threaded rod 302 to adjust the first U-shaped block 307 and the pressure roller 309 to descend;

[0031] 2) Then cooperate with the extension rod 305 and the first spring 306 to make the pressure roller 309 fully adhere to the surface of the material for film covering;

[0032] 3) Then open the second telescopic rod 406 to drive the lifting plate 407 to move, cooperate with the articulated rod 408 to drive the vertical plate 409 to move to play the role of alignment and adjustment;

[0033] 4) Finally, open the first telescopic rod 401 and the second motor 405 to drive the conveyor belt 403 and the sponge layer 404 to rotate, thereby playing the role of alignment and anti-curling.

[0034] In summary, the anti-curling mechanism of the laminating machine, rotating the threaded rod 302 can drive the top plate 303 to move downward, through the movement of the top plate 303 to drive the first U-shaped block 307 and the compression roller 309 to move downward, thereby adjusting the distance between the compression roller 309 and the conveying belt 2, then through the alignment and anti-curling structure 4 to adjust the material, the material enters the inside of the protective cover 301, opens the first motor 308 to drive the compression roller 309 to rotate, and through the first spring 306 cooperates with the extension sleeve 304 and the extension rod 305 to make the compression roller 309 and the outer surface of the material more closely, the laminating film appears bubbles, thereby achieving the purpose of conveniently adjusting the height of the compression roller 309, increasing the practicability of the device, opening the second telescopic rod 406 to drive the lifting plate 407 to move, through the movement of the lifting plate 407 to drive the articulated rod 408 and the vertical plate 409 to move along the auxiliary rod, thereby adjusting the distance between the vertical plates 409, thereby ensuring that the material is adjusted before entering the protective cover 301, then after laminating, open the first telescopic rod 401 to drive the second U-shaped block 402 to descend, and start the second motor 405 to drive the conveyor belt 403 to rotate, and through the rotation of the conveyor belt 403 to drive the sponge layer 404 to rotate, and to be combined with the laminated material to absorb excess moisture to prevent curling, thereby achieving the purpose of conveniently aligning the material and preventing curling.
