Description

Packaging equipment for improving packaging density and shaping of filamentous materials

Technical Field

The utility model relates to a filamentous material especially pipe tobacco packing technical field specifically is the equipment that can improve filamentous material packing density and plastic.

Background

Because filamentous material is mostly fluffy state, therefore density is lower, like pipe tobacco, tobacco stalk silk, reconstituted tobacco leaf silk etc. lower unit packaging weight leads to packing, storage, cost of transportation higher, and because fragile characteristic, impact, the vibration in transport, transportation can lead to material inside friction, striking and cause certain garrulous. Therefore, the packaging mode of improving the packaging density without causing the fragmentation of the material is an effective way for effectively reducing the packaging, storage and transportation cost of the materials.

Chinese patent publication No. CN201457743U discloses a tobacco leaf compression box filler, which compresses tobacco leaves at high density by mechanical force, thereby reducing gaps and lowering filling height, but once the filamentous material is compressed, a large amount of tobacco leaves are crushed. The vacuum packaging machine disclosed in chinese patent publication No. CN110775368A utilizes a vacuum-pumping mode to compress the volume of the material, so that the material can be preserved and protected against oxidation, and this mode can effectively prolong the shelf life of the product, but when packaging filamentous materials, the internal pressure is gradually reduced along with the vacuum-pumping, and under the action of the external atmospheric pressure, the material can be deformed by unshaped shrinkage in all directions, so that the shape of the vacuum-packaged material is irregular, which is unfavorable for storage and transportation, and along with the reduction of the pressure in the vacuum-pumping process, after the material is greatly shrunk, the edge lining bag film can be compressed by the atmospheric pressure and tightly attached, so as to form sealing, so that the air in the material cannot be continuously pumped out, and the vacuum-pumping effect is affected.
