[0009] The output end of the sensor abuts against one side of the rotating bracket, the sensor is electrically connected to the controller, and the controller is electrically connected to the motor.

[0010] In some embodiments, the wrapping roller set includes:

[0016] In some of the embodiments, the film on the roll is outputted by passing through a second rotating roller, a third rotating roller, a fifth rotating roller, a fourth rotating roller and a sixth rotating roller in sequence.

[0017] In some of the embodiments, the seventh rotating roller passes through the lower bracket plate and is rotatably connected to the base plate at one end thereof, and is sleeved with a first gear, the first gear is meshed with the second gear, the second gear is meshed with the third gear, an elastic mechanism is connected to the third gear, and the second gear and the third gear are both rotatably connected to the base plate.

[0028] When in use, place the gypsum board to be packaged under the opening of the protective cover, and pull the film on the roll to the left. At this time, the film drives the rotating bracket to rotate clockwise with the seventh rotating roller as the center. At the same time, the rotating bracket disengages from the sensor, and the sensor transmits a signal to the controller. The controller controls the motor to drive the first rotating roller to rotate, output the film on the roll, and package the gypsum board. At the same time, due to the clockwise rotation of the rotating bracket, the first gear, the second gear and the third gear are driven to rotate, and the third gear pulls the elastic mechanism. At this time, the spring is in an extended state. After the gypsum board is packaged, the film under the opening of the protective cover is disconnected. At this time, the spring returns to its original state under the action of its own elastic force, driving the first gear, the second gear and the third gear to rotate in the opposite direction, thereby causing the rotating bracket to rotate counterclockwise and reset until the rotating bracket abuts against the sensor again. At this time, the sensor transmits a signal to the controller, and the controller controls the motor to stop rotating, completing the entire gypsum board packaging. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Specifically, in the technical solution of the present invention, the sensor 3 cooperates with the controller to control the power on and off of the motor, thereby controlling the output and stop of the roll film. The sensor 3 adopts a contact sensor. Once the rotating bracket 2 is separated from the detection end of the sensor, the motor immediately starts working to output the film through signal transmission.

[0056] Preferably, the mounting plate 14 is mounted on one side of the base plate 1 by bolts;

[0057] Specifically, the mounting plate 14 connected by bolts is easy to disassemble, and since most of the components in the elastic mechanism are connected by hooks, the entire elastic mechanism can be disassembled by the bolts, which is more practical and more convenient for repair and maintenance.
