When the clamping roller 310 clamps the old aluminum film and cuts the old aluminum film, the rotary driving part 314 drives the clamping roller 310 to rotate so as to wind the free end (tape splicing end) of the old aluminum film, which can ensure that the old aluminum film is stably clamped by the tape splicing assembly 30 and ensure that the surface of the old aluminum film to be attached is accurately butted with the adhesive tape on the new aluminum film when the tape splicing assembly 30 butts the old aluminum film and the new aluminum film.
In the present disclosure, the transfer portion 32 includes a swing arm 320 and a deflection driving portion 321. The pinch roller 310 is connected with the swing arm 320, and the swing arm 320 is driven by the deflection driving part 321 to drive the pinch roller 310 to deflect. The deflection driving part 321 may include a deflection motor, an output shaft of which is disposed at one end of the swing arm 320, and the pinch roller 310 is disposed at the other end of the swing arm 320. When the deflection motor works, the clamping roller 310 can deflect, so that the clamping roller 310 is moved to the position of the new aluminum film, namely the position of the gummed paper on the new aluminum film on the first unreeling shaft 10a or the second unreeling shaft 10b, and the splicing of the new aluminum film and the old aluminum film is realized. It should be noted that, in an embodiment, the swing arm 320 may be provided with an edge finding mechanism, and the swing amplitude of the swing arm 320 can be calculated by combining the roll diameter of the new aluminum film, and the output of the deflection motor is adjusted, so that the swing arm 320 is ensured to move the pinch roller 310 to the adhesive tape of the new aluminum film, and the roll change of the new aluminum film and the old aluminum film is realized.
It should be noted that the reloading device further comprises a position sensor 40, and the position sensors 40 are arranged on both unreeling shafts 10. It should be noted that the position sensor 40 may be a color sensor. The color sensor is used for acquiring the position of the gummed paper on the new aluminum film so as to determine the preset position.
It should be noted that, in the present disclosure, a feeding system is also provided, and the feeding system has the above-described reloading device. By the aid of the reloading device, coil replacing time of a loading system can be saved, and loading efficiency is improved; meanwhile, the roll changing device is an automatic roll changing device, so that the labor cost of roll changing is saved.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
