The invention provides a bonding method for a non-
woven fabric handle of a packaging box. The bonding method includes the following steps that firstly, glue is applied to a plate; secondly, a strengthening belt is stuck to the glue applying position; thirdly,
punching is conducted at the position where the strengthening belt is bonded; fourthly, glue is applied to the strengthening belt and the plate; fifthly, the non-
woven fabric handle penetrates from the
punching position, the non-
woven fabric handle is stuck to the glue applying position of the strengthening belt and the plate, and laminating is conducted; sixthly,
ultrasonic welding is conducted on the non-woven fabric handle and the strengthening belt through an
ultrasonic welding device; and seventhly,
air cooling is conducted. According to the bonding method for the non-woven fabric handle of the packaging box, due to the fact that the strengthening belt is arranged at the position where the non-woven fabric handle is stuck, the stress area is enlarged, strength of the plate can be ensured, and tearing is prevented; and due to the fact that the non-woven fabric handle and the strengthening belt are integrally welded through the
ultrasonic welding technology,
instability of
hot melt glue is reduced, the bonding degree of two non-woven fabric belts is increased, the bearing capability is higher after integration, the handle
carton box is suitable for bearing larger and heavier goods, selectivity of clients is improved, and popularization is higher.
