Packaging equipment of roof-shaped packing box

Abstract

The invention relates to packaging equipment of a roof-shaped packing box. The packaging equipment comprises a, bottom packaging equipment, b, filling equipment, c, nitrogen feeding equipment, d, top packaging equipment and e, a transmission mechanism, wherein the bottom packaging equipment comprises a central spindle, a rotating shaft, a bottom forming folding device and an ultrasonic wave sealing device; the top packaging equipment comprises a welding anvil and a plumb joint matched with each other; the surface of the welding side of the welding anvil comprises three welded gaskets in a combining manner; the surface of the welding side of the plumb joint is provided with countersinks in array distribution; an ultrasonic wave generator is arranged in the plumb joint and is close to or away from the welding anvil through air cylinder connection driving. The packaging equipment uses high-temperature nitrogen ultrasonic wave for sealing and forming and has the most remarkable advantages of not generating condensed water, not polluting food to avoid food safety loophole and protecting a product from oxidative deterioration.

Description

[technical field] [0001] The invention relates to a packaging device, in particular to a packaging device for gable packs. [Background technique] [0002] On the old-fashioned liquid filling machine, the roof pack (fresh house) product is sent from the packaging carton to the filling machine and then comes out of the filling machine outlet to become a complete and qualified product, which is roughly formed by bottom sealing, liquid product filling and Top sealing molding and other related processes. [0003] Such as image 3 as shown, image 3 discloses the structure of the bottom suture molding equipment in the prior art. In this equipment, a rotating shaft that rotates in the middle is included. The side of the rotating shaft is fixed with one end of the mandrel. At the station, the cartons set on the mandrel are heated by an electric heating furnace in sequence, folded and formed by the bottom folding forming mechanism, and finally bonded to the bottom pressing plate.

Problems solved by technology

[0009] The purpose of the present invention is to provide a new packaging structure to solve the problem that the furnace heating cannot be filled with nitrogen in the prior art

[0010] Another object of the present invention is to solve the problem that the conventional ultrasonic heating device heats and welds different heights and large-area plane welding is difficult

Makes it possible to apply ultrasonic welding to roof cladding welding
