Currently, the tape is usually pasted on the surface of the magnetic strip manually by workers, and the magnetic strip is cut. However, on the one hand, the stability of manual tape sticking is insufficient, which can cause the tape to be skewed, and the tape can not be adhered when pressed by hand, so that the surface of the tape is puffy, which affects the normal layout of the product. At the same time, it is not convenient for workers to cut the magnetic strip. On the other hand, the use of manual tape sticking has low work efficiency and greatly increases the cost of labor.

During the process of tape sticking, the guide mechanism can be used to guide the glue sticking direction of the glue sticking mechanism, without stopping the glue sticking action and manually changing the direction, so as to effectively improve the efficiency of the tape sticking process. However, on the one hand, the invention cannot guarantee that the tension of the tape surface remains stable during the conveying process, which can cause the tape to warp and produce puffy surface.

[0020] In summary, the present application has the following beneficial effects:

[0021] 1. The joint butt joint device is provided with a group of symmetrically and synchronously counter-rotating rotary arms, and the adhesive tape fixing and cutting assembly is fixedly arranged at the end of the rotary arm, when the joint of the adhesive tape moves to between the adhesive tape fixing and cutting assembly, the adhesive tape fixing and cutting assembly fixes the new adhesive tape and the old adhesive tape and then cuts the joint of the adhesive tape, the cutting edge of the shearing knife is flush with the side end face of the mounting plate, so that the cutting end of the adhesive tape can be flush with the side end face of the mounting plate, so that the synchronous counter-rotation of the group of rotary arms can prevent the phenomenon of overlapping or spacing of the new adhesive tape and the old adhesive tape from occurring when the ports of the new adhesive tape and the old adhesive tape contact, so as to ensure that the adhesive tape pasted on the magnetic stripe is uniform in thickness everywhere, and the efficiency of pasting the adhesive tape is ensured;

When the cutting end of the new tape contacts the old tape, the sliding plate no longer abuts the tape on the mounting plate because the communication tape needs to be put into the tape communication groove. In order to avoid the tape from automatically sagging and affecting the normal communication of the tape, the U-shaped abutting plate abuts both ends of the tape to avoid the tape from sagging. After the communication tape is put in, the sliding plate rises to paste the communication tape to the joint of the new tape and the old tape to realize the communication.

[0023] 3. The tension adjusting device is arranged to enable the tape to be always taut and the tension of the tape to be adjusted, so that the tension of the tape is stable, thereby ensuring the quality of the tape pasting and avoiding the problem of tape hollowing. The tape flattening assembly can also exert a certain force on the tape at any time to make the tape pasting more flat. The arc-shaped conveying groove is arranged in the tape conveying seat to make the change of direction of the tape more stable during movement, further improve the flatness of the tape pasting, and also reduce the floor space occupied by the tape pasting equipment.
