[0002] At present, there are roughly two types of packaging tapes popular in the domestic packaging market. One is OPP transparent tape, which is suitable for low-end and simple packaging. Its characteristic is that the sealing and packaging operation is convenient. The disadvantage is that the box is not flat after sealing, and its material is not easy to decompose and is not environmentally friendly. The other is kraft paper tape, which is gradually becoming popular in daily life and industrial packaging because of its environmentally friendly material.

[0003] After the cartons are connected by metal nails, it is necessary to tape the inner surface of the cartons, that is, stick kraft paper tape on the metal nails to prevent the metal nails from scratching the products.

[0004] The existing method of sticking kraft paper tape on metal nails is to do it manually. The specific process is to open the box by hand, then stick the kraft paper tape on the metal nail, and then cut the kraft paper tape with a knife. For mass production, this method requires more manpower to complete, and the labor cost is extremely high; and there are many subjective factors when it is done manually, and it is difficult to ensure that it is accurately stuck on the metal nail.

[0026] A driving wheel 10 is provided on the fixing seat 1 through a wheel seat 12. The driving wheel 10 slightly protrudes from the upper surface of the fixing seat 1 and is at the same level as the fixing upper wheel 2. The driving wheel 10 is powered by an external motor to rotate, which is conducive to pushing the carton forward. The tilting arm 5 is provided with a staggered notch 52 that can stagger the wheel seat 12 to avoid interference with the tilting action of the tilting arm 5. The overall structure is compact and the occupied space is reduced.

[0027] The driving wheel 10 drives the floating upper pasting wheel 3 to rotate through the linkage gear set 11, which is more conducive to the transportation of the kraft paper tape and the early pasting effect. The linkage gear set 11 includes a first gear 111, a second gear 112, a third gear 113, a fourth gear 114 and a fifth gear 115.
