Bag-in-bag packing equipment

Abstract

The invention discloses bag-in-bag packing equipment which comprises a first bag feeding type packer, wherein a first bag discharging working station is arranged at the outer circumference of a first indexing rotary table of the first bag feeding type packer. The bag-in-bag packing equipment is characterized by further comprising a second bag feeding type packer, wherein a second bag feeding working station, a bag opening and charging working station, a second heat-seal working station and a second bag discharging working station are arranged at the outer circumference of a second indexing rotary table of a second bag feeding type packer; the bag opening and charging working station is arranged over against the first bag discharging working station correspondingly; bag opening suction nozzles are arranged above a machine clamp on the bag opening and charging working station, and can open the mouth of a large packing bag clamped by the machine clamp on the bag opening and charging working station during work; a feeding hopper is arranged above the bag opening suction nozzles; bag-taking chucks are arranged between the feeding hopper and the first bag discharging working station, and can clamp a small packing bag on a machine clamp on the first bag discharging working station and transfer the small packing bag to the feeding hopper during work. The bag-in-bag packing equipment has the advantage that bag feeding-type automatic packing production of sleeving between the big packing bag and the small packing bag can be realized, so that sanitation is guaranteed, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of packaging machinery, in particular to a bag-in-bag packaging equipment capable of realizing the bag-in-bag automatic packaging production of a large bag covering a small bag. Background technique [0002] The bag-type packaging machine is used for the packaging of granules, various foods, seasonings, sauces, and liquids, and is widely used in the market. For some materials such as hot pot seasoning, if only one packaging bag is used for packaging, the damage will cause serious pollution. Therefore, it is generally necessary to use another outer packaging bag to cover the inner packaging bag for double-bag packaging with a large bag and a small bag. The work process is all done manually at present, the speed is slow, the labor intensity of the workers is high, and hygiene cannot be guaranteed. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present inve...

Problems solved by technology

For some materials such as hot pot seasoning, if only one packaging bag is used for packaging, the damage will cause serious pollution. Therefore, it is generally necessary to use another outer packaging bag to cover the inner packaging bag for double-bag packaging with a large bag and a small bag. The work process is currently done manually, the speed is slow, the labor intensity of the workers is high, and the hygiene cannot be guaranteed.
