Bonding method for non-woven fabric handle of packaging box

Abstract

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.

Description

Technical field [0001] The invention relates to the manufacturing field of packaging box handles, in particular to a method for bonding a packaging box non-woven fabric handle. Background technique [0002] Existing packaging boxes generally use plastic handles to be stuck in the openings on the packaging box, and some use non-woven handles. When using non-woven handles to produce such packaging boxes, you need to Punch two holes on the upper panel of the packing box, and then insert the two ends of the non-woven fabric handle through the two holes on the outer side of the upper panel, and then glue them to the inner side of the upper panel. This fixing method is not Reliable, small weighing, easy to fall off, and the cardboard attached to the non-woven handle is easy to tear due to uneven force. Summary of the invention [0003] In order to solve the problems in the prior art, the present invention provides a method for bonding non-woven fabric handles of packaging boxes. [0004...
