[0006] The film feeding unit includes a frame, film roll, front wheel, long feed channel, short feed channel, rear wheel, pressing roller, and film clamping cylinder. The long feed channel is equipped with a long clamping bar, an air suction mesh group, and a large negative pressure chamber. The short feed channel is equipped with a short clamping bar and a small negative pressure chamber.

[0007] The shearing unit includes a shearing cylinder, a collection ramp, and a collection box;

[0008] The feeding unit and the film-removing unit are respectively fixedly connected to the frame.

[0009] Furthermore, both the long and short material channels are provided with suction mesh groups on their surfaces.

[0010] Furthermore, long clamping bars and short clamping bars are provided on the sides of the long and short material channels.

[0011] Furthermore, the feeding device is fixed to the frame and can be adjusted left and right.

[0012] Furthermore, a scale is provided on the side of the frame.

[0018] Furthermore, the collecting ramp is located at the rear end of the shearing cylinder.

[0019] The present invention also provides a system and method for laminating and replacing the backing paper of signage products. The method uses the system described in any one of the above-mentioned inventions to perform lamination and backing paper replacement, and the steps are as follows:

[0020] Step 101: Place the roll film at the front end of the frame, separate the film and paper, place the transparent protective film on the long feed channel, and let the white release film pass through the upper front and rear wheels, overlap with the protective film, pass under the pressure roller, and pass through the open scissors.

[0021] Step 102: Start the large negative pressure chamber and the small negative pressure chamber. The suction net group will tightly adsorb the transparent protective film onto the long material channel and the short material channel. Start the discharge cylinder. The feeding unit will push out the product. The product will fall onto the transparent protective film. Start the clamping cylinder and the platform pushing cylinder. The film peeling unit will roll up and remove the auxiliary film.

[0022] Step 103: Disconnect the suction mesh group, start the film clamping cylinder, disconnect the platform push cylinder, clamp the overlapping film and move it to the end, so that the upper release paper, the middle product and the lower protective film are bonded together after passing through the pressure roller;

[0023] Step 104: After the finished product passes through the scissors and is in place, the cutting cylinder cuts the product, and the product falls into the collection box via the collection ramp.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] By separating the protective film and release paper in the roll film, the label products are placed in the middle by automatic feeding. The adhesive auxiliary film is removed by the film peeling unit, and then the label products are attached to the middle of the film paper. The scissors cut the blank area in the middle of the adjacent products to realize the collection of individual products. This system is reasonably designed, easy to use, and has high operation efficiency.
