[0023] In the embodiment, lap joint unit 2 includes vertical plate, vertical plate is arranged at the position of installation vertical block, and suction roller 201 is arranged on vertical plate, and suction fan is arranged on suction roller 201, and suction fan is used to control suction roller 201, and suction roller 201 is used to carry out negative pressure adsorption operation to new release paper after replacement, and lower roller is arranged below suction roller 201, and sawtooth cutter 202 is arranged at the position of one side of lower roller, and driving cutting cylinder 203 is arranged on sawtooth cutter 202, and driving cutting cylinder 203 is arranged on vertical plate, and sawtooth cutter 202 is used to cut old roll release paper to be replaced, and tension roller 204 is arranged below lower roller, and tension roller 204 is used to adjust release paper tension when replacing roll, wherein, it needs to be noted that the novel cutting mode is not limited to swing arm type.

[0024] In the embodiment, cloth storage frame unit 3 includes arcuate frame body, guide roller 301 is rotationally arranged at the position of one side of arcuate frame body bottom, guide roller 302 is rotationally arranged at the position of other side of arcuate frame body bottom, drive sprocket 303 is arranged at the position of one side of upper portion in arcuate frame body, first shaft stick is fixed in the middle shaft of drive sprocket 303, passive sprocket 304 is arranged at the position of one side of lower portion in arcuate frame body, second shaft stick is fixed in the middle shaft of passive sprocket 304, drive motor 311 is connected to the outer end of first shaft stick, and drive motor 311 is arranged on arcuate frame body.

By setting up the flip-type double-station release paper unwinding unit 1, the overlapping unit 2 and the cloth storage rack unit 3, the release paper can be unwound normally without stopping the machine, and the preparation work before overlapping is ensured. There is no need to shut down the system or slow down the speed to replace the release paper, which effectively improves production efficiency, ensures the quality of the film and reduces material loss. The tension roller 204 ensures that the tension of the release paper in the coating section is constant. 3 The cloth storage is controlled by the drive motor 311. The drive chain drives the cloth storage roller 306 to move up and down, and the torque of the drive motor 311 is set to control the cloth storage tension. When the new and old release paper rolls are switched and overlapped, the system sends a signal, and the cloth storage roller 306 is driven by the drive motor 311 to slowly descend, so that the cloth storage roller 306 stops at the lowest position. The normal unwinding of the release paper is controlled by the PID adjustment mode based on the feedback of the tension roller 204. The release paper unwinding adopts the speed control mode. The cloth storage tension of the cloth storage rack unit 3 is adjusted to the same tension as the production line. The working tension of the glue coating machine 5 is constant and the same working speed is maintained. The required length of the release paper is adjusted by the cloth storage rack unit 3. After the overlapping is completed, the release paper unwinding is switched to the PID adjustment mode, and the cloth storage roller 306 is programmed to slowly run to the high position, thereby making the system run smoothly and ensuring that the product quality is not affected by the roll change.

[0027] Working principle: When using this system, the first station 101 unwinds normally, and the second station 102 is loaded with a new roll of release paper and then affixes double-sided tape on the inner side of the release paper. When the first station 101 has about 100-300m of unwinding remaining, the second station 102 is controlled to flip to the first station 101. At this time, the first station 101 is loaded with a new roll of release paper, and the adsorption fan is turned on to make the adsorption roller 201 in a negative pressure state. The release paper is manually pulled to the position of the adsorption roller 201 and adsorbed, and the protective paper of the double-sided tape is peeled off. At this time, the second station 102 is unwound. After the tail of the old roll of release paper at the second station 102 reaches the meter alarm, press the overlap button, the suction roller 201 moves downward until it is pressed against the lower roller, and then rotates about 100mm, driving the cutting cylinder 203 to push the serrated cutter 202 to pierce the release paper, cutting off the old roll of release paper. At this time, under the adhesion of double-sided tape, the new roll of release paper and the old roll of release paper are successfully overlapped, the first station 101 starts to unwind normally, the second station 102 stops rotating, remove the old roll and replace it with a new roll, and then reload it into the second station 102.

[0028] Although the embodiments of the present application have been shown and described, it is to be understood that for the purpose of the present application, the embodiments can be changed, modified, replaced and varied in many ways without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended embodiments and their equivalents.
