Technical Field

[0001] The present application relates to the technical field of optical film production equipment, and in particular to an automatic film rolling equipment for continuous production of optical films. Background Art

[0002] When producing optical films, automatic film rolling equipment is required to roll up the produced optical films.

[0003] Existing automatic film rolling equipment generally includes a frame and a winding roller. The frame is arranged at the end point of the optical film production line. The winding roller is detachably connected to the frame and is connected to the rotating motor so as to wind up the optical film by driving the winding roller to rotate through the rotating motor. When the optical film on the winding roller is wound to a certain thickness, the worker will use scissors or other cutting equipment to cut the optical film on the winding roller from the optical film produced by the production line, and then remove the wound winding roller from the frame, and then install a new winding roller on the frame and use the winding roller to continue to wind up the strip.

[0004] Because the automatic film rolling equipment cannot continue to roll up the strip produced by the optical film production line when the winding roller is replaced, workers need to shut down the optical film production line before replacing it every time, which slows down the production progress of the optical film production line.

[0005] In view of this, it is necessary to provide an automatic film rolling device for continuous production of optical films. Utility Model Content

[0006] In order to solve the problem that the existing automatic film rolling equipment needs to shut down the optical film production line when replacing the winding roller, thereby slowing down the production progress of the optical film production line, the present application provides an automatic film rolling equipment for continuous production of optical films.

[0007] The present application provides an automatic film rolling device for continuous production of optical films, which adopts the following technical solution: comprising a frame, a rotating rod, a material receiving assembly and a rotating frame driving device, wherein the middle portion of the rotating rod is hinged on the frame;

[0008] The material receiving assembly comprises a winding roller, a standby roller and a roller driving unit, wherein the winding roller is detachably connected to one end of the rotating rod, the standby roller is detachably connected to the other end of the rotating rod, and the roller driving unit is drivingly connected to the winding roller and the standby roller, and can drive the winding roller to rotate to wind up the optical film strip;

[0009] The turret driving device is connected to the rotating rod, and the turret driving device can drive the rotating rod to rotate and drive the winding roller and the standby roller to approach or move away from the discharge port of the optical film production line.

[0010] By adopting the above technical solution, when the optical film strip on the winding roller is wound to a certain thickness, the worker can drive the rotating rod to rotate by controlling the turntable driving device so that the winding roller and the spare roller can exchange positions, and then cut off the optical film strip connected to the winding roller, and then wind the cut optical film strip onto the spare roller, and finally drive the spare roller to continue to wind the optical film strip through the roller driving unit, so that the winding roller can be replaced while keeping the optical film production line working.

[0011] Specifically, the roller driving unit includes a driving gear, a driving motor, a gear reduction box and two driven gears. The driving gear is rotatably mounted on a hinge shaft between the rotating rod and the frame. The driving motor is arranged on the frame and the output shaft of the driving motor is transmission-connected to the input shaft of the gear reduction box. The output shaft of the gear reduction box is transmission-connected to the driving gear. A driven gear is provided on the rotating shafts of the winding roller and the spare roller. The driving gear is transmission-connected to the two driven gears through a chain.

[0012] By adopting the above technical solution, the driving motor can transmit power to the gear reduction box, so that the output shaft of the gear reduction box can drive the driving gear to rotate, and the driving gear can drive the driven gear to rotate through the chain, thereby driving the winding roller and the spare roller to rotate.

[0013] Furthermore, the roller driving unit further comprises two tensioning gears, wherein a tensioning gear is provided between each of the driven gears and the driving gear, and each of the tensioning gears can abut against the chain and tension the chain.

[0014] By adopting the above technical solution, the tensioning gear can tension the chain between the driven gear and the driving gear to increase the contact area between the chain and the driven gear and the driving gear, making it easier for the driving gear to transmit power to the driven gear.

[0015] Furthermore, it also includes a control component, which includes a controller and a display screen. The controller is electrically connected to the drive motor and the turntable drive device and can control the opening or closing of the drive motor and the turntable drive device. The display screen is arranged on the top of the frame and is electrically connected to the controller.

[0016] By adopting the above technical solution, workers can control the opening or closing of the drive motor and the turntable drive device through the controller, and the controller can display information such as whether the drive motor is turned on and whether the turntable drive device is turned on on the display screen, so that workers can understand this information intuitively.

[0017] Specifically, safety chucks are provided at both ends of the rotating rod, the winding roller is detachably connected to one of the two safety chucks, and the standby roller is detachably connected to the other of the two safety chucks.

[0025] When the spare roller needs to be replaced, the spare roller is located between the winding roller and the discharge port of the optical film production line, and the optical film strip passes through the bottom of the spare roller and between the pressure roller and is connected to the winding roller. When the pressure roller rotates upward around the hinge axis of the swing arm, the pressure roller can abut the optical film strip between the roller surfaces of the pressure roller and the spare roller.

[0026] By adopting the above technical scheme, when the spare roller needs to be replaced, the worker can drive the rotating rod to rotate the spare roller to a position between the winding roller and the discharge port of the optical film production line. At this time, the optical film strip will pass from the bottom of the spare roller and between the pressure roller and be connected to the winding roller; then the rotating motor is controlled to drive the swing arm to rotate upward, so that the swing arm drives the pressure roller to rotate upward around the hinge axis of the swing arm, and pass through the gap between the spare roller and the winding roller, and the pressure roller will abut against the optical film strip and lift the optical film strip upward during the movement, and finally abut the optical film strip between the pressure roller and the roller surface of the spare roller, so that the worker only needs to cut off the optical film strip between the pressure roller and the winding roller first, and then stick the end of the cut optical film strip on the spare roller, and then continue to wind the optical film strip through the spare roller, so that it is convenient for the worker to connect the optical film strip to the spare roller.
